AI Technical Summary
Existing sand removal machines are not efficient at crushing larger sand blocks when vibrating on the screen plate, and the sand storage bins after sand removal do not have a cooling function, which affects the working efficiency of the cooling drum.
A production line including a sand crusher, an elevator, a cooling sand silo, and a water bath cooling drum was designed. The sand crusher rapidly crushes sand blocks by using a movably connected grid plate and a screen plate with asynchronous vibration frequencies. The cooling sand silo discharges heat through a vent plate and a guide hood. The water bath cooling drum undergoes secondary cooling through spray pipes and a flow equalization plate.
It improves the efficiency of sand removal, enables rapid crushing and secondary cooling of the molding sand, improves cooling efficiency, and meets the reuse requirements of lost foam molding sand.
