Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing equipment, in particular to a dust removal device for a shot blasting machine. Background Art

[0002] When in use, the shot blasting machine needs to eject projectiles at high speed for surface grinding. In a closed environment, the shot blaster ejects projectiles to impact the surface of the casting, knocking off sand, scale, burrs, rust and other debris on the surface of the casting. The knocked-down impurities are sent to the shot blaster again for recycling together with the projectiles by the shot circulation device. During the transportation process, the impurities mixed in the projectiles are separated by the dust separator. After the projectiles hit the surface of the casting, they will be knocked down together with sand, scale, dust and other particles of different sizes. Therefore, in order to recycle the projectiles, other impurities need to be separated from the projectiles. During the separation process, a large amount of dust is mixed in the exhaust gas, which makes it difficult to handle the inside of the machine later and affects the grinding effect.
