How to assemble the sandblasting unit with their own hands - a simple guide for quick assembly

Old gas cylinder will find new life as sandblasting

You do not know how and what to collect sandblaster with their hands? Then you will be useful to my experience in this field. I'll tell you what materials and parts you need to prepare and give a simple assembly instructions from the beginning to the test run.

How does sandblaster

Work powerful industrial plants forcing operators to wear protective suits and masks

The principle of operation is simple sandblasting - compressed air or water entrain abrasive material which is a high speed acts on those or other surfaces.

Due to the increase and decrease the amount of material passing through the nozzle can be adjusted and abrasive consumption spot area of ​​contact with the surface. That is, the more abrasive passes through the nozzle of the second, the greater part of the surface can be cleaned. But at the same time, abrasive consumption will increase by several times.

Water sand blasting their own hands can be collected on the basis of the garage washing Karcher

By varying the pressure with which the air is supplied, it is possible to make an impact on the work surface of the abrasive weaker or stronger. If relieve pressure, a jet of sand hardly go astray paint layer. Increasing the pressure, it is possible to ensure that the sand leave micro-relief on metal.

The compact sandblasting machine factory production works in the same way as the self-made counterparts, but looks neater

Currently produced Fitting abrasive action, which is supplied under pressure either air or water. Due to the simplicity and ease of use of the most widely used modification of operating on compressed air.

Sand in the air plants should be dry, otherwise it will clog the nozzle

As an abrasive used sand, chippings and other plastic particulate abrasives with a grain size of not more than 3 mm. In order to provide maximum cleaning efficiency, the machine is filled only seeded and only pre-dried sand.

What can you gather yourself

Among the requirements for a self-made apparatus, note the simplicity of the assembly with his own hands and efficacy. The unit will be assembled by a simple diagram of the available components.

The device, which will collect, so simple that even drawings are not needed - will be sufficient ordinary schemes

Sandblaster The device is as follows:

• As the receiver applies a gas cylinder;
• Above the balloon is backfilled in dry sand, also through the top nozzle will be supplied to the air under pressure;
• In addition, compressed air is supplied to the balloon down to the outlet.

Thus, the sand will fall under gravity and under pressure into the bottom pipe. Immediately sand will be picked up and a stream of compressed air directed to the nozzle.

Now that the principle of the sandblaster is clear, we will prepare the necessary materials and components.

What is needed in order to collect sandblasting

Illustration	Description of materials and components
	Gas bottle of 50 liters. Needed one standard steel cylinder. The price of the new bottle is about 2 thousand. rubles, b / u option can be bought for about 500 rubles.
	Compressor. To work sandblasting equipment need a compressor with a capacity of 800 liters or more. Optimal - Garage installation with a discharge pressure to 12 atmospheres. Since the work will be carried out with dry sand, it is desirable that the compressor has been provided an oil separator.
	Bulk flow filter. Needed flow water filter replaceably filler in the flask. In place of the regular filter element are covered with the silica gel beads, and the device will dry the air flow fed into the cylinder.
	silica beads. Silica need a lot, so it is best not to buy bags and a large package from a pet store. Silica need enough to fill the flow-through filter flask.
	oxygen hose. Thus the hose will connect all of the elements in the structure. Ordinary hose is not suitable, since, because of the high pressure air will poison both the attachment areas, and in areas of kinks and abrasions.
	Yokes tightening galvanized. In order to attach a rubber hose to the fitting or to the threaded portion of the tube, require metallic clamp, which is worn on top of the hose and tightened due scroll screw.
	Ball valve. It will need at least two taps. Valves need to adjust the air inlet to the system and to adjust the intensity of the abrasive jet at the exit from the nozzle. Stop valves should be made of brass, as cheap cranes silumin body quickly break .
	hydraulic fittings. In the course of the cylinder connections with other components of the system will take several ebbs and tees. Tees, you can buy ready-made, and the sleeves can be cut into dies.
	Fitting threaded quick. This kind of fittings required to connect all components of a rubber hose into a single system.

Assembly Instructions

Illustration	Description stage
	Preparing the balloon for receiver. If the container b / y, twist the valve and fill the internal volume of water. Thus, from a cylinder will come out all traces of the gas and the subsequent assembly will be secure.
	Install faucet and fittings. In place of the nozzle neck is screwed with a ball valve and with two tee fittings.
	Mounting supports. In the upper part of the cylinder 3-4 welds support. supports design may be different, as long as the inverted bottle on a stand has been steady and unsteady; In addition, the pillars height should be such that the bottle upside down state does not touch the floor crane.
	Mounting the air supply unit. The bottom of the cylinder is welded tee; To one allotment tee welded tubular extension to which is secured a compressed air supply hose; All connections in this node qualitatively boil continuous suture, in order to ensure maximum tightness.
	Sealing plugs on top of the cylinder. Compound cylinder and plug should be as dense, because, if the air is bled, fail to achieve the desired compression. To seal in the stopper can be pressed into the rubber ring or as shown in the image, to apply a rubber insert.
	Install an air dryer. By using an existing tubular extension cord through the tee mounted filter, the inside of which will be laid silica gel; At the entrance to the filter installed ball valve.
	Compound dryer with the bottom nozzle. By the withdrawal of the tee near the dryer hose attached; The other end of the hose connected to the nozzle near the bottom of the container supports. Both compounds prihvatyvaet and tightened with clamps.
	Installation of handles for carrying pot. To the receiver it easier to move from place to place on both sides of the cylinder are welded handles. Due arms, can be assembled structure will move together.
	Manufacturing of nozzle. Peskostruek nozzle should have a cross section of 3-4 mm. Made nozzle must be of metal or of materials similar in strength. In our case, it has been applied the finished ceramic insulator, which is used in electrical work.
	gun assembly. Impromptu nozzle through the hose section attached to the ball valve, and the whole structure is fixed more protracted clamps; screwed piece of tubing 30 cm long with the free end of the tee.
	Setting the quick connector on the filter. In the ball valve, after-flow filter, quick-set through a hose fitting, which will be connected through the air supply from the compressor; Connection is made specially through the hose, so that it was flexible; Lots connection clamps are tightened.
	Connect a hose from the compressor. Hose designed for high pressure compressor with quick connect connector.
	filling of desiccant. The flask flow filter silica beads fall asleep. Complete filling enough for about a week of daily use of the unit.
	Trial run. After homemade sandblaster ready sand fall asleep the neck including a compressor and wait 5-10 minutes until the pressure in the receiver rises to 4 atmospheres. After this, open the screen on the output from the receiver, and then on the nozzle. Try to keep the gun firmly, because of the high pressure, it will be taken out of the hands .

To summarize

We have considered the simple assembly instructions sandblaster, and now you can collect the same setup on their own. Questions on the assembly unit can be specified in the comments.
