Here we are with another brand new structure by the ‘make it extreme’ team, a Sandblaster.
This structure is capable for multiple uses such as removing the rust from old objects and coatings as well as writing on many different kinds of materials like glass, stone and others.
Our own design of the particular structure aims to recycle the sand in order to be able to use it more than once.
Step 1: Tanks
Thus, we used two tanks to reach this particular outcome as when the one tank is in use for sandblasting the other one which is not in use, it will be able to keep the sand in it. Therefore, after the sand is ran out from the tank which was used for sandblasting and with the help of some valves the function is reversed by carrying out the same process with the second tank this time. In the future, we are planning to make a recycling system for the sand, as well.
To create the two tanks, first we took four tanks of domestic LPG (liquefied petroleum gas) to cut them and then, we made two larger ones. Our tanks are linked with screws in the middle in order to enable us to access their inside surface, if it is necessary.
Step 2: Air - Pressure Regulator - Valves
The air is inserted by a robe which is connected with an air compressor and it passes through with the help of a pressure regulator. Then, the air in the tank pressures the sand and another supply connects with the valve, in which the sand is mingled with the air (mixing valve) and next, it moves towards the sandblaster gun within a robe. Therefore, opening the valve we realize that the sand comes out of it in a great speed and hitting our object we have the outcome that we just mentioned above. The inlet of our tank, where the sand is inserted, it opens when the pressure of the tank is in zero and automatically, closes when the air is inserted in our tank. This fact makes the placement of the sand and our sand blaster extremely easy to use.
The indications regarding the pressure applied in our tanks are showed by two pressure gauges that each one is placed per tank. Also, for safety issues, we placed two safety air valves 12 bar on our tanks as well as two exhaust valves that remove the air from the tanks when is necessary.
Step 3: Paint - Test
To make our sand bluster even easier to use, four wheels have been placed to become a movable tool, easy to be used in our workplace, too.
Reaching pressures of 8 bar from our compressor, our sand bluster works great and it has excellent results. Also, putting some water in our tanks, we can clean our place from dirt that cannot be easily removed with the water pressure in our home. In addition, putting some sand in one of the two tanks and water in the other we can transform our structure into a hydro-sand blaster in no time…
