[0013] 1. Compared with the traditional sandblasting machine, the utility model uses compressed air to push the abrasive to form a high-speed jet to wash the object to process the surface of the object. The abrasive and the debris washed off the surface of the object will diffuse in the air, forming a large amount of smoke and dust, which brings inconvenience and pollution to the working environment.

[0014] 2. When removing slag and dust, the fan inhales air with smoke and dust, which enters the filter chamber through the slag removal pipe. The large solid particles in the air are first filtered through the filter to prevent the large solid particles from entering the fan and causing fan failure. The filtered smoke and dust enter the fan through the smoke and dust pipe, and then enter the water tank through the dust removal pipe. The water in the water tank is used to wash away the fine particles in the smoke and dust. Finally, the clean air is discharged through the exhaust pipe to solve the problem that the sandblasting machine will generate a lot of smoke and dust during use, which increases the practical value of the device.

[0015] 3. When in use, if the device needs to be moved, just push the table top directly. The wheels under the table legs allow users to push the device with less effort. The outer shell can be rotated through the rotating rod so that the wheels can rotate in any direction, allowing the device to move in all directions.
