The honeycomb type wind recycling sandblasting room mainly consists of two parts: one part is the sandblasting system; the other part is the sandblasting system. Material recovery, separation and dust removal system.

The working principle of the blasting system in the blasting room is: the sand is stored in the blasting In the sand tank, when the sandblasting operation is performed, the combined valve on the sandblasting tank will act to lift up the sand-sealing support on the sandblasting tank and pressurize the sandblasting tank. At the same time, the sand valve under the sandblasting tank of the sandblasting host is opened, and the booster valve is opened. In this way, since the sandblasting tank has been pressurized, the sand is forcibly pressed out from the sand inlet of the sand valve of the sandblasting host to the sand outlet, and the sand at the sand outlet of the sand valve is accelerated by boosting the airflow. The accelerated sand-air flow mixed flow passes through the sandblasting pipe to the high-speed spray gun. In the high-speed spray gun, the sand is further accelerated (boosting the air flow to supersonic speed), and then the accelerated sand is sprayed at a high speed to the workpiece. Treat the surface of the workpiece to achieve the purpose of surface cleaning and strengthening of sandblasting operations.

The working principle of the sand material recovery, separation and dust removal system in the blasting room is: The air flow enters the sandblasting room through the shutters on both sides of the sandblasting room, and then enters the sandblasting studio through the uniform flow plate at the top of the sandblasting room, forming a top-to-bottom airflow in the cross section of the sandblasting room. The sand, dust and cleaning materials in the room enter the abrasive separation system through the honeycomb sand suction floor, and the abrasive and dust are separated through the abrasive separator. The dirt enters the dust removal system with the airflow, and after being filtered by the dust removal system, the clean air is discharged into the atmosphere, and the dust and dirt are stored in the dust tube for regular cleaning.
