Description

Technical Field

[0001] The present application relates to the technical field of impeller production and processing, and in particular to a sand processing device for casting a water pump impeller. Background Art

[0002] After the water pump impeller is cast, it usually needs to be polished to ensure surface smoothness and quality. Considering the complex structure of the water pump impeller, the common treatment method is to use sandblasting equipment for surface polishing.

[0003] However, since conventional sandblasting equipment uses fluid to drive sand through the nozzle to spray at high speed, the spraying process itself causes certain wear to the nozzle, making the nozzle a vulnerable part, resulting in the nozzle of the sand processing equipment being easily worn out, increasing maintenance costs.

[0004] Conventional sandblasting equipment has certain problems because the sand is driven through the fluid of the high-speed nozzle, which may cause wear to the nozzle, making it a consumable part.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0012] The sand falling assembly comprises a sand bucket arranged on a bucket-shaped shell frame, and a screen is arranged at the lower end of the sand bucket for slowing down the falling of sand materials.

[0013] Preferably, a rotating cylinder is provided on the side of the bucket-shaped shell frame, and the rotating cylinder is transmission-connected with the support arm to drive the support arm to rotate, thereby realizing the flipping of the insertion shaft around the support arm.
