DIY simple construction vacuum cleaner

DIY construction vacuum cleaner: how to make from the old, instruction and video

Construction vacuum cleaner. a necessary thing during repair and construction work. It’s just worth the equipment is quite expensive. Not every master can afford to buy such an unit, and a household vacuum cleaner will not be able to cope with a lot of dust and construction waste. As a rule, such a purchase is made by professionals who make money in construction work. However, if the device is required from case to case, from the current situation there is a way out. You can make a construction vacuum cleaner with your own hands. You will need an old vacuum cleaner, several construction and electric parts that are always in the household. The missing elements can be bought in the store. And also patient and highlight a little time to create a construction vacuum cleaner.

The construction vacuum cleaner differs from the household with the following nuances:

• There are more filters in the construction vacuum cleaner to delay large and small particles. Increased filtration area allows you not to overload the engine, reduce the period of time between cleaning the device.
• Household vacuum cleaner is not designed for a high load. In its production, more attention is paid to design and compact sizes.
• Building vacuum cleaners have a large size, impact.resistant, durable, designed for all types of construction dust.
• In the domestic vacuum cleaner, the incoming air is used to cool the engine. Plaster particles cannot be removed by a filter system that are installed in a domestic vacuum cleaner. The use of a vacuum cleaner has not been for its intended purpose, will quickly remove it from the working condition.
• The power of building vacuum cleaners starts from the value of 850 W. For households, this is the ultimate value.
• Technical characteristics of building vacuum cleaners allow you to work without a break for a long time. In this case, the engine does not overheat.

The principle of operation is the same for all types of vacuum cleaners. The fan that comes to working condition using an electric motor creates a vacuum in the system. Dust particles fall into the flow of air and undergo cleaning on filters. After that, the air is thrown out.

Before starting the manufacture of a construction vacuum cleaner with your own hands, you should know what types of devices are:

Cyclone building vacuum cleaners

The work is based on the use of centrifugal force. Thanks to this force, the absorbed garbage is sent to the tank. During operation, the device is very noisy. The cause of the noise is the blows of garbage particles against the wall of the container and about each other.

The principle of operation of the cyclone vacuum cleaner is shown below in the figure:

Vacuum cleaners with a built.in aquafilter

In simple words, this is a vacuum cleaner with a water filter. The principle of operation is that air with dust particles passes through a layer of water. The dirt remains in the water, and the purified air is thrown out.

Save models

Models differ depending on the type of vacuumber. There are disposable and reusable, paper and fabric options for bags for collecting dust.

Construction vacuum cleaners are separated depending on the purpose:

There are models that are included as soon as the equipment forming waste begins to work. Such a sample device can also be made with your own hands. In the “Video” section, you can find out how to make it and what you need for this.

What construction vacuum cleaners can be done with your own hands. The principle of work and purpose

Water filter vacuum cleaner

With the help of a construction vacuum cleaner equipped with an aquafilter, you can clean any surface. In addition, a model with a water filter, perfectly cleans the air in the working room. This is important in the case of work in which a lot of dust is formed.

Before starting work, follow the scheme of the future vacuum cleaner.

What will be required for the manufacture of a construction vacuum cleaner with a water filter from a household vacuum cleaner:

• A bucket of plastic. Choose containers with a lid. The volume of the bucket should be at least 10 liters.
• Adapters for connecting plumbing pipes and fittings.
• Plastic panel.
• On the side surface of the bucket we cut out two holes. The diameter of the holes and adapters must match.
• In one of the holes we insert an adapter with a pipe that should not reach the bottom of the container by about a couple of centimeters. In the process of work, this hole will be connected to a hose to suck dust.
• We cut a circle from the PVC sheet and install over the adapter. The diameter of the circle should be such that it is fixed in the upper third of the capacity. Part of the plastic circle, which is located opposite the holes. is cut off. This is necessary for free air advance through the system.
• Insert the pipe into the next hole. The hose from the vacuum cleaner will join it.
• To fix all the details, we use a sealant for plastic.
• 2.5 liters of water are poured into the bucket. Self.made waterfilter cover with a lid.
• We attach the hoses. Construction vacuum cleaner with aquafilter is ready.

So that the procedure is clear, see

A household vacuum cleaner, cyclone filter and a set of hoses will be required. Modules can be combined in one container. This simplifies the task. To implement the second option, you must first prepare details and tools:

Tank about 40 liters. The volume of the tank can be larger. It is important to choose it in such a way as not to allow the passage of pollution to the vacuum cleaner. Experience shows that it is impractical to set a container with a capacity of less than 10 liters.

A segment of the plumbing pipe. To ensure a smooth transition from the container to the hose, you can use plastic adapters, couplings.

• A hole is cut out on the side surface of the tank to enter the pipe or adapter. It is important to observe the direction of the pipe. by tangent to the wall of the container and the oblique section at the input of the pipe. Otherwise, when the pipe is cut at a right angle, it is impossible to achieve a full separation of solid particles and air. The oblique angle allows you to form the right direction of the air masses.
• On the surface of the lid also make a hole under the pipe. Introduce the pipe into a container to a depth of about 10 cm.
• The input and output pipe should have the same diameter. Suitable plumbing pipes for 50 mm.
• To ensure a reliable tight connection, the joints between the pipe and the container are treated with sealant.
• The tank cover should fit tightly at the top. This will increase the performance of the installation.
• Test the finished installation. Correct the admissed shortcomings in work.

If the process description is not clear, look

The scheme below presents the principle of the construction vacuum cleaner.

The sequence of actions in the manufacture of a vacuum cleaner:

• The containers are connected to each other so that the cover of one bucket is attached to the lid of another bucket.
• For fixation, silicone glue is used. For reliability, the necessary construction metizes are used nuts and bolts.
• A hole in the form of a circle with a diameter of about 50-70 centimeters is drilled in the center of the united surface.
• In the side surface of the container, which is below, the hole is drilled. This place of connection of the hose through which dust is absorbed. The pipe from the hose is inserted into the hole so that the flow of air masses is directed by tangent to the wall of the bucket. This location of the pipe helps to create the effect of “cyclone”.
• The engine from the old vacuum cleaner is placed on the upper capacity cover. A hole of the desired diameter is also made under it. The installation site of the engine can be shifted to the side to attach the filter without interference. However, you can use the experience of experienced masters and install the engine in the center. To understand the filter mounting method, watch the video at the end of this section.
• The engine is attached to the lid using a clamp from a durable wire. Tightness is provided with silicone glue or sealant.
• There are no clear restrictions on choosing a filter. For a capacity of 25 liters, a filtering device with a diameter of 25 cm is suitable. The length of the filter in this case is about 40 cm.
• To fasten the car filter, use the hairpin of the desired length.
• The motor can be covered with a body from an old vacuum cleaner. Some craftsmen use a simple bucket, providing it with the necessary holes, fasteners and a switch. The solution depends on your imagination and skill.

Mini vacuum cleaner from plastic pipes and a hair dryer from a hairdryer

From the remains of plastic sewer pipes you get an excellent mini vacuum cleaner for a home workshop. With the help of this homemade, you can quickly put things in order on the desktop.

As an engine, the master uses a motorbike motor (along with the impeller). But you can take any other suitable engine, and make the impeller for the shaft yourself.

First of all, we cut off a piece of a plastic sewer pipe. And then it will be necessary to cut off part of the bell. The author also cuts off a ring from the revision.

In a previously cut off a piece of PVC pipe, paste the plug. Previously, the plastic itself must be made with rough with sandpaper.

Inside the pipe (already on the opposite side of the plug), the master glues a plastic ring. A part of the thread cut off from the revision will be based on this ring. it also needs to be glued to supergli.

The main stages of work

At the next stage, cut off the bottom from the plastic plug. cut it, heat it with a hairdryer and bend, turning the edges in different directions.

In the lid from the revision we drill two holes: we insert a piece of pvc pipe into the first hole, in the second. a plastic discharge by 90 degrees. The previously made part must be glued to the pipe segment.

Using two transitions from large diameter to small, we make a case, inside of which we put a motor from a hair dryer. As a hose for a vacuum cleaner, we use corrugation.

At the last stage, we start assembly.

How to make a vacuum cleaner from plywood and wood

What is the most important problem in the carpentry workshop? Correctly! A lot of wood dust. To make cleaning effective, we recommend using not a household vacuum cleaner, but a construction.

True, such an unit is not cheap, so we offer you an alternative option. to make a vacuum cleaner for a carpentry workshop with your own hands.

To make a vacuum cleaner, we will use those materials that there are always plenty in the carpentry workshop. plywood and wood.

We also need an electric motor, a corrugated hose and a sewer plastic pipe. As a filter we will use a filter for the aquarium.

The author of YouTube Ayo Bikin Sendiri shared his personal experience in the manufacture of a vacuum cleaner for a carpentry workshop.

The main stages of work

First of all, it will be necessary to make the impeller. From plywood we cut out two circles of the same diameter.

In one of them, drill a hole under the connecting sleeve (so that you can put on the shaft of the electric motor), in the other we cut out the hole.

The author made a woods on a strip saw blade. Glue the blades to the first disk, glue the second disk with a hole on top.

At the next stage, from plywood we collect the box of the required size.

He will have two side walls. The electric motor will be attached to the first. The second wall will simply tightly close the box.

We place the impeller in an additional case, inside which we make a duct channel (how to make it. shown in the video).

Next, collect the frame from wooden rails and pull the soft filler for the aquarium filter. In this case, it is a synthetic winterizer.

Install a homemade filter inside the box, having previously fastened two stops.

Additionally, drill a hole through which the dust will fall into the housing and glue a piece of a sewer plastic pipe. We collect everything together. We put on a corrugated hose on the pipe.

All dust will be assembled inside the case in front of the filter. It is very simple to remove it from the body. The replacement of the filter will not take much time.

DIY vacuum cleaner for garage

Many motorists and not only have a garage that periodically needs cleaning. In such cases, a household vacuum cleaner can not always cope with the amount of garbage, and the acquisition of a special construction vacuum cleaner is not the pleasure of cheap. In this case, you can build a vacuum cleaner for a garage with your own hands.

Scheme

A homemade vacuum cleaner of two buckets is performed (you can use conventional thin-walled paint containers). A safety ring is installed inside each bucket, which will prevent their compression under the influence of vacuum. Rings can be made of plywood, 12-15 mm thick. In this case, their diameter should correspond to the size of the containers, and the width is about 10 mm.

The lid of the lower bucket is screwed to the bottom of the upper, not forgetting to previously apply a layer of silicone between them. Then a hole is drilled, with a diameter of 40 to 70 mm.

A hole under the hose is made in the wall of the lower container. At the same time, the air flow should be directed along the wall, which will make it possible to work with a cyclone effect. A hole under the turbine is marked and cut out on the second cover. The location of the turbine should be shifted somewhat to the side. This is due to the placement of the filter. it is fixed with a hairpin, which is located in the center. The engine can be used by any, including from the old household vacuum cleaner. Usually, these are turbines from Buran, which had wide popularity at one time and could be found in almost any house. Attach it to the cover with the help of a wire clamp (since there is no possibility), and also do not forget about the layer of silicone for sealing.

The filter also put any. In the case of 25-liter paint buckets, the best option will be the filter whose diameter does not exceed 250 mm and long to 430 mm. A small.sized bucket may act as a cover of a motor compartment. Turning button. a regular light switch. It will also require the basis on which a homemade device will be installed. They can become plywood support on the wheels.

DIY vacuum cleaner for workshop

For people who are densely engaged in woodworking, sooner or later the issue of efficient removal of chips and sawdust is acute or later, especially when working indoors. As practice shows, with large volumes, even strong industrial vacuum cleaners often cannot cope, the filters of which are too quickly clogged with waste. That is why, so often masters resort to independent assembly of the device, which shows excellent results when collecting garbage and dust.

Scheme

There are many different chip separator schemes. One of the most effective designs is considered a separator-submarver, the assembly of which is performed in stages. First of all, the separator itself gathers:

You can do almost everything with your own hands. Quite often, during construction work, there is not enough construction vacuum cleaner that would help remove garbage and do more and more. Thanks to the advice of Novate.ru can quickly create a completely reliable model of a construction vacuum cleaner using ordinary and some improvised means. With such an invention, dust and sawdust will not be annoyed during the repair, and you will not have to spend money on professional inventory.

Homemade cyclone from household vacuum cleaner

This type of construction vacuum cleaner, independently made of home, is best suited for cleaning chips from wood or metal. But it does not cope with cement dust so well, for this purpose it is better to use the second option presented in this article. A homemade cyclone from a household chips cleaning can quite effectively absorb kilograms of garbage even without a frequent change of filter bags if you build a “separator” for it with your own hands.

Collection of improvised means

This will require: a regular vacuum cleaner; sewage system for 90 degrees with a diameter of 4 cm from polypropylene; a bucket with a lid of dense plastic, for example, from putty; plastic sewer pipe with a diameter of 4 cm; Crown 40 mm, which can be replaced with an ordinary stationery knife.

Beginning of work

First you need to make a hole in the bucket cover right in the center. It will be most convenient to use the crown. If it is not, you can cut the hole with a clerical knife, first for convenience, making the opening of the opening with an awl. The second hole is made closer to the edge of the lid, not reaching the rib of stiffness. Two sewer taps are inserted into the prepared holes.

So that the air does not pass and the bounces are held as well as possible, it is recommended to glue them. To improve clutch and enhance gluingness will help process the edges of the plastic edges with a file or sandpaper. The glue must be applied with a thermal pistol, a thick layer, so that it performs and ensures complete tightness.

The final stage of work

The next step is the connection of the sewer drive with the right angle. This will complete the creation of the design of the improvised separator. Now you need to put on a lid with taps on a bucket. A hose for air intake from a vacuum cleaner is connected to the central hole. A hose is inserted into the corner connection, in which it will be convenient to remove construction garbage in the future. Now you can proceed to the use of a vacuum cleaner.

Useful advice: sealing rings will help to improve the work of a home.made construction vacuum cleaner, which in size will correspond to corrugated hoses of a household vacuum cleaner.

Additional recommendations

To create an effective model, you should pay attention to some subtleties. /

So that a construction vacuum cleaner made of ordinary household works, it is better to work, it is better to take a bucket that will be higher. The power of the vacuum cleaner should more or less correspond to the size of the additional design. If there are several buckets in stock, then they can be used sequentially, thereby improving air purification. At the same time, you will not have to take out the garbage and clean the buckets. For a domestic vacuum cleaner of high power, it is best to use not a plastic bucket, but a metal. dense material will not be subject to curvature and deformations.

An improved version of a building vacuum cleaner made of household

Construction dust cleaning will be effective with an improved version of a home.made vacuum cleaner. /

In order for a homemade construction vacuum cleaner to effectively absorb not only large construction garbage, but also dust, and does not break, it should be supplemented with a previous model with a slight improvement. This role will play a filter bag, which should not be made of tissue material. To extend the service life of this element and make it reusable, you should adjust the bag to the size of a plastic bucket, if necessary. After that, fix the lower edge using a plastic cable canal and a piece of polypropylene pipe.

A longitudinal cut is made on the tube, the width of which will be about half a centimeter. Then this part is coated with glue and glued to the bag-filter of the vacuum cleaner. A prepared tube is inserted into the slot. Inside the bucket, the filter bag is connected to the rubber adapter from the corrugation. The lid of the bucket should be tightly closed. Due to the fact that the reusable filter is used, all the dust will get there, and not overload the household vacuum cleaner, not intended for very intensive cleaning of construction dust. If you do not take care of such an addition, the vacuum cleaner will constantly overheat and may burn out.

Often household problems can be solved independently using improvised means. And these 10 tips from homegrown inventors will help with household chores.

How to make a construction vacuum cleaner from improvised means

Taking to build or repair something, it is not necessary to put up with an abundance of dust “in the process”. In such cases, it is easiest to use a special construction device, but it is worth considering that the of such devices are high, and the need for its use may not exceed several times. It is more advisable to collect a construction vacuum cleaner with your own hands. In the article, the master plumber will tell you how to make a construction vacuum cleaner from improvised means.

The principle of operation and technical characteristics

The basis of the homework is the usual household vacuum cleaner. Instead of a standard dust collection bag, we connect a larger container through the connecting hose, for example, a galvanized technical bucket. The garbage absorption hose remains the same, and is connected directly to the capacity.

Its main task is when absorbing coarse dust or chips, prevent it from getting into a vacuum cleaner. This is possible due to gravity and friction forces, thanks to which large particles of garbage move along the spiral trajectory along the walls of the container, gradually settling on its bottom. It turns out such a separator for separating different fractions of pollution. And for cleaning the room it remains to combine the entire device with a single platform and make it convenient to move.

• Household vacuum cleaner;
• A tin bucket for garbage with a tightly closed lid;
• Taps for sewer drains made of polypropylene, inclined at an angle of 90 degrees. 40 mm (2 pcs);
• Additional hose for a vacuum cleaner.

We start working with the preparation of the capacity cover. In it, drill holes for the corners.

One in the center, the second with the edge of the lid near the stiffener rib.

If the milling cutter for holes does not fit in size, the holes after drilling can be slightly rubbed by wrapping the pipe or other round blank with sandpaper.

Insert the plastic corners in the adjusted holes. We set the central with lateral eyeliner, the extreme. with a vertical.

We adjust the absorption hose from the vacuum cleaner in size, and connect to the central corner on the lid of the bucket.

The end of the hose, if it is not removable, it is necessary to cut.

We collect a mobile cart from plywood. We mark the cutting of plywood to the dimensions of the vacuum cleaner and the funded capacity, and cut it out with an electrician.

From the remnants of the plywood sheet, we cut out the sides for the cart of arbitrary width.

Between the vacuum cleaner and a bucket, we mount a plywood partition, which will replace us with a handle for a cart.

Platform, pen and two sides are connected to self.tapping screws. In order not to break down the layered plywood, it is worthwhile to pre.sprinkle the fasteners with a smaller diameter drill. It is better not to glue the connections, because if necessary, the cart will be easier to disassemble.

Before fixing the partition, cut a hole in it under the hilt. We use the same mill for pipes with an electric screwdriver for this, and the jigsaw.

On the back of the platform, we fix the four furniture wheels on the rotary axis with self.tapping screws.

Now you can paint the finished product with aerosol or any other paint. This will extend the life of the cart, and will make its appearance more attractive, and the surface is less than the brand.

Having put out both elements on the cart-a vacuum cleaner and a bucket-it remains to pull them off any belt-piece and connect them to the network. It is very easy to move such a device, and if necessary, you can disassemble and bring directly to any machine in the workshop, saving time and effort for tiring cleaning!

Homemade inexpensive cyclone for household vacuum cleaner

This review shows the process of making a home.made inexpensive cyclone for a conventional household vacuum cleaner. This device will come in handy during cleaning in a home workshop and garage.

For the manufacture of cyclone, a large plastic bucket (for example, from paint) and segments of sewer PVC pipes will be required.

First of all, it will be necessary to make the basis of the mobile platform. For this, the master cuts out two narrow boards and two. wide. You can also use plywood or wood-based.

The main stages of work

At the next stage, we connect the boards with the help of screws. After that, it will be necessary to screw the wheels. The site is ready.

From the boards sawn down in size, the author makes two racks that are interconnected by a jumper. A plastic bucket will rest on this jumper.

The assembled design must be fixed on the basis. Please note that the support jumper should be located at a certain height so that it can be installed under it with a vacuum cleaner.

In the lid of the plastic bucket, two holes must be drilled. In them, the author inserts segments of sewer pipes.

At the last stage, it remains only to paint the site and racks with a stain (or paint), after which you can start the final assembly.

Shipable valves for cyclone from plywood and PVC pipes

Many masters have long acquired cyclones. However, one thing is one thing. if you connect one machine to it and forget it, and it’s quite another. to constantly connect different hoses from different machines.

In order not to rearrange these hoses every time, the author decided to make simple gate valves for cyclone from pieces of plywood and PVC pipes.

First of all, we saw off the plywood from a sheet of three identical stripes. Dimensions. approximately by eye.

Next, we saw them into three rectangular and six square blanks in which it is necessary to drill holes under the diameter of the PVC pipe (50 mm).

It will also be necessary to cut off six pieces of PVC pipes: three pieces with a bell and three. without a bell.

The main stages of work

At the next stage, we glue segments of a plastic pipe into square blanks from plywood. With the help of two barnies, we connect part of the valve body to each other.

A valve itself is placed between them. a rectangular piece of plywood with a hole. On the ends of this valve, the author fasten pieces of plywood, so that it is more convenient to take on it.

Similarly, we make the other two valves. We attach a plastic tee to the cyclone, and the gate valves to it.

Homemade vacuum cleaner for the carpentry workshop ⁠ ⁠

It all started with the fact that I began to fall asleep with sawdust. Any action with the power tool generates sawdust. I tried to take advantage of the Kerherov construction vacuum cleaner immediately, but it stops working after 5 minutes of work. The filter just clogs. Therefore, it was decided to make a vacuum cleaner yourself. Honestly, this is my third vacuum cleaner, and there will be many more, people ask to repeat.

It all starts with a capacity. It was decided to do the container independently, because I could not find a barrel without narrowing for 100 liters and light. Therefore, I made a frame of plywood and filled it with cellular polycarbonate. There is a ring inside so that the barrel does not collapse.

With the help of a milling circul, he cut the rings and made the separator’s body, into which a stream with garbage enters the tangent and under the influence of centrifugal force falls through a slot down the barrel. The foolish.fiber stove for a round wall took a fool, do not repeat my mistakes! Plywood 3 or 4mm is better suited for this. The pipe is made of plug.in chopper 50mm.

The separator is covered with a hole with a hole on which the filter housing is mounted. The filter element is used from the injector VAZ car, they have an affordable price.

On the lid of the filter case, the engine is mounted from a powerful vacuum cleaner with a native dumpfer ring, which reduces sound and vibration.

So that the barrel does not crush when the hose is overlapped in it installed a safety valve. Simple and reliable design, you can even adjust even 🙂

The case is covered with Shumka. Installed switch and outlets for connecting power tools.

The block of the vacuum cleaner is assembled from the connected load with the shutdown delay. A peculiar current relay. 🙂 The photo is a prototype.

Here is a photo of the vacuum cleaner test. Near Kerher. He has wheels from the old chair to drag him behind him 🙂 and a pen to shake.

The vacuum cleaner took its place on the stand in the corner and climbs out of there only for cleaning. The hose from it goes under the ceiling along with the cable to connect the tool to all the workshop working surfaces.

I will post a photo of the other brothers of my vacuum cleaner. First option. It has been working for a long time in a strange garage, the owner asks to repeat 🙂 a bucket of 25 liters. A trial option without any frills, pure functionality.

This terrible monster has my father. not a very stable design, but it is just a beast! When the air is overlapped, half a meter of the hose sucks inside and collapses a bucket. 🙂

Soon I will make a cap for a CNC on a three.phase asynchronik and another “household” vacuum cleaner on order.

Ready to answer your questions, ask.

quality work! We periodically install vacuum cleaners, mainly in the cottages, but also in one apartment, they got into a vacuumade. The power system of 40mm with diameter, in the walls, in the desired places, spreads out rosets for connecting the hose. The vacuum cleaner itself, the size of yours, is put in technical means with an exhaust outward. all. On the sockets, the contacts are low.current. hose with a brush, 10 meters. but surprisingly light, on an ordinary vacuum cleaner others.Just like sockets, “scoops” are placed. Slop at the floor level, with a knife lever. Pressed. Everything was sucked that he took her. In short, everything is so that the housekeeper is happy! ))

At first it seemed that it was for the pseudo.boiling layer installation.

At my work, I use a homemade filter for a vacuum cleaner for toner, and this is a much thinner, light and everywhere of a testable crap. And something tells me that my filter is cheaper and more efficient. As a case, I use a regular plastic barrel of 100l. with a lid and a squeezing clamp. Filter element. Airmer from KAMAZ or double from the MAZ and one and the other in the form of a bucket with a bottom. As a cyclone, some S-shaped rubber pipe from an unknown machine (found in the garbage dump), but to be honest, it is effective only for the first 10 kg. toner, and in total about 20. The filter with a long stilett is attached to the lid there and the output pipe. Input in the body of the barrel at the top. To enhance the plastic ring of aluminum from a thick cable inside the barrel and a phonern pancake on the lid. Any vacuum cleaner without alteration and parsing. I think that the filtering element from heavy trucks here is more suitable than Vazovsky, just imagine what volume of air drives a powerful diesel and the difference in price is not significant and is going to- everything is versed in a couple of minutes.

Explanations according to the scheme of a home.made vacuum cleaner:

Automatic machines (2x poles) QF1 and QF2 protect the circuits for connecting the power tool (Roset XS1), respectively, and the control circuit of the engine of the vacuum cleaner. When the tool is turned on, the current of its load flows through the diodes VD2-VD4 and VD5, they are selected according to the directory due to a large voltage drop in them at a direct current. On a chain of three diodes, when one (we call it “positive”) half.wave of the current, a pulsating voltage drop is created, which is through the fu1 fuse, the diode of the VD1 and the resistor R2 charges the capacitor C1. FURDER FU1 and varistor RU1 (16 volts) protect the control scheme from damage during overstrain, which can occur, for example, during a breakdown) in the diodes of VD2-VD4 diodes. Schottky diode VD1 was selected with a small voltage drop (to “save” the already small volts) and prevents the discharge of capacitor C1 during a “negative” half.wave of current through the diode VD5. The resistor R2 limits the capacitor charge current C1. The voltage obtained on C1 opens the OPTRON DA1, the thyristor of which is included in the control control circuit of the engine speed controller. A variable resistor R4 to regulate the engine speed is selected the same face value as in the board of the vacuum cleaner regulator (it is removed) and made in remote (in the body from the dimmer) to accommodate the upper cover of the vacuum cleaner. The resistor r is parallel to it. S2 switch “VKL/Off” in the break of the circuit of the resistor R4 serves to manually turn on the vacuum cleaner. Switch S1 “automatic/manual”. In manual control mode, S1 is turned on and the regulator current goes along the R4 (R). S2 chain. S1. In automatic mode, the S1 is turned off and the regulator current goes along the R4 (R) chain (r)-4 DA1 outputs. After disconnecting the power tool due to the large capacitance of the capacitor C1 and the inertia of the engine, the vacuum cleaner continues to operate about 3-5 seconds. This time is enough to draw the remains of garbage from the hose into the vacuum cleaner.

Automatic launch scheme is assembled on a layout board. Switches S1, S2, dimmer body (for placing a variable resistor R4) and the XS1 socket are selected from one not very expensive series, so to speak for aesthetics. All elements are placed on the upper cover of the vacuum cleaner, swept of a 16 mm woody boat and a pasted PVC edging. In the future, it will be necessary to make isolated housings for boards in order to protect the parts under voltage from an accidental touch.

To power the vacuum cleaner, a three.core flexible cable was selected in the rubber insulation of KG 32.5 (5 meters) and a fork with grounding contact (do not forget about electrical safety and fight with static electricity). Given the short.term intermittent operating mode of the vacuum cleaner, together with the power tool, the selected cross.section of the cable is enough so as not to heat up. A thicker cable (for example, kg 34), respectively, more severe and rude, which would create an inconvenience when using a vacuum cleaner. It was decided to refuse from the cable watching device that was in the donor vacuum cleaner, since the contacts existing there would not withstand the total load of the vacuum cleaner and the power tool.

The upper cover is fixed using a hairpin and a lamb nut.

For the convenience of removing the upper cover, the engine is connected to the control circuit through the connector. The body of the engine and the vacuum cleaner join the protective grounding conductor. To cool the regulator circuit in an output pipe, a small hole drilled to create an air duct inside the motor compartment case.

In order for a garbage bag to be inserted into the garbage collection, the upper edge was pushed by the rubber seal for doors cut along the rubber.

And so that the garbage bag does not suck inside the cyclone due to the air leaks through leaks, it is necessary to make a small hole in it.

The dilution and testing of the resulting vacuum cleaner took place already during the repair, so to speak in “combat” conditions. The craving, of course, is many times more powerful than that of a household vacuum cleaner, which would not have been enough for a couple of minutes of work with construction garbage. Relatively heavy garbage from concrete almost completely besieges in the garbage collection and an additional filter does not need to be cleaned for a long time, while the thrust is uniform and does not depend on the degree of filling the garbage collection. The dust from putty (in the form of flour) is very light and, accordingly, is worse filled with a cyclone, which makes the auto.filter periodically clean. The task of making a dust supply was not set and therefore not carried out on this function of the test.

The resulting device eventually turned out to be operational and has already passed the check when repairing one room. Now I am considering it more likely as an acting layout from the series “It will turn out or not for the sake of interest”.

The main disadvantages of this design:

-poor frustration of light fine dust, which can be solved by introducing the second stage of smaller cyclones.

I would like to thank all my friends, who helped with ideas and materials in the construction of this “Pepelats”. And special thank you very much to my beloved wife Yulia for supporting me in my hobbies.

We proceed to the creation of a construction vacuum cleaner

Initially, it is necessary to do a garbage collector that needs to be finalized. Armed with a screwdriver, unscrew the wheels from the base of the vacuum cleaner and tightly glue all the obtained holes obtained with tape. After the nameplate is removed, its hole also needs to be sealed with tape.

All fixers are removed. Now with the help of a corner grinder, it is necessary to free the case from all the rivets and put a plug, previously wrapped in insulating tape. Then make a hole in the bottom with a drill, size 43-45 mm. As a gasket, the seal is taken, approximately 3-5 mm in thickness.

In the garbage collection, which was converted, you need to add a gasket, centering the pipe and bucket cover. Take a drill for 2 mm and use a drill to make holes that will continue to hold the lid.

Next, holes are made outside the suction pipe. Before doing this, it is necessary to put the marks at an angle of 15 degrees. Using metal scissors, make a hole. After that, attach the pipe using screws. For maximum tightness, it is necessary to carefully soak the bandage with glue and wrap it around the pipe.

The nuances of such an apparatus

In order to assemble your construction vacuum cleaner, you must have a power unit on hand, the turnover of which should be at least 6,000. As for the improvised material, it can almost always be found at home. As a donor for the engine, you can use not only the old vacuum cleaner, but also the washing machine.

Some craftsmen use power units from kitchen machines for a homemade vacuum cleaner, but do not forget about their tendency to frequent breakdowns due to the inability to withstand high load.

If the power unit is found, then you need to take care of its tightness. You will also need a fan. Very often, an ordinary bucket is taken as a housing for the vacuum cleaner, in which a hole is made. Naturally, a garbage container and a filter that can be made with your own hands are needed.

The presented videos shows several variations of the assembly of a construction vacuum cleaner. It is recommended to study them if you decide to create a home.made model.
