Description

TECHNICAL FIELD

[0001] The utility model relates to foundry surface sand cleaning technical field, concretely to a foundry surface sand cleaning device. BACKGROUND

[0002] Sand casting is a casting method for producing castings in sand molds. Since sand casting has lower cost, simpler production process and shorter production cycle than other casting methods, castings such as exhaust branch pipes of automobiles are produced by clay wet sand process. After the exhaust branch pipe is completed by casting, it is cleaned.

[0003] The application number CN202322457723.1 discloses a wet sand foundry surface sand cleaning device, which comprises a bottom plate and other structures. The hollow shaft and the brush disc can be rotated by the setting of the rotating motor, the driving gear and the driven gear. The inner wall of the casting is cleaned by the brush disc. The dust and debris generated during cleaning are absorbed by the setting of the dust suction fan, the connecting pipe, the dust collection box, the dust suction hose and the dust suction cover. The dust and debris are not only collected conveniently, but also prevented from floating into the air to affect the workshop environment. The above structure can collect the sand while cleaning and avoid the floating of the sand dust. However, the dust generated by the polishing of the edge position of the brush disc will float around, which cannot be absorbed by the dust suction mechanism in the application, so the dust removal effect is poor.
