Working Principle of Sand Blasting Booths

Working principle of Sand Blasting Booths

The honeycomb type wind recycling Sand Blasting Booths mainly includes two parts: one part is the sand blasting system; The other part is the sand recovery, separation and dust removal system.
The working principle of the sandblasting system in the sandblasting room is that the sand material is stored in the sandblasting tank of the sandblasting host. When sandblasting is carried out, the combined valve on the sandblasting tank acts to jack up the sand sealing bracket on the sandblasting tank and pressurize the sandblasting tank. At the same time, the sand valve and the booster valve under the sandblasting tank of the sandblasting host are opened. In this way, since the sandblasting tank has been pressurized, the sand material is forced out from the sand inlet of the sand valve of the sandblasting host to the sand outlet, and the sand material at the sand outlet of the sand valve is accelerated by boosting the air flow. The accelerated sand mixture flows through the sandblasting pipe to the high-speed spray gun. In the high-speed spray gun, the sand is further accelerated (the booster air flow is accelerated to supersonic speed), and then the accelerated sand is sprayed onto the surface of the workpiece to be processed at a high speed to achieve the purpose of surface cleaning and strengthening of sandblasting.

Sand Blasting Booths' working principle of the sand material recovery, separation and dust removal system of the sandblasting room is: the air flow outside the sandblasting room enters the sandblasting room through the louvers on both sides of the sandblasting room, and then enters the sandblasting studio through the uniform flow plate on the top of the sandblasting room. A top-down air flow is formed in the cross section of the sandblasting room, and the sand material, dust, cleaning materials, etc. in the sandblasting room enter the abrasive separation system through the honeycomb sand absorption floor, The abrasives and dust are separated. The useful sand enters the sandblasting tank for continuous recycling. The dust and dirt enter the dust removal system with the air flow. After filtering by the dust removal system, the clean air is discharged into the atmosphere. The dust and dirt are stored in the dust drum for regular cleaning.
