Description

Technical Field

[0001] This application relates to the field of sand processing cooling technology, and more specifically, to a cooling device for sand processing equipment. Background Technology

[0002] Sand cooling equipment is an indispensable supporting equipment for lost foam casting. It comes in a wide variety of types with excellent performance. It is economical and easy to operate manually. It has dust removal and screening functions. The fully automatic type has a high degree of automation and has functions such as cooling, dust removal and screening, which has reached the standard of intelligent equipment use.

[0003] In related technologies, in order to solve the problem that most sand cooling devices have poor cooling effect and excessively large shells, resulting in a significant reduction in heat dissipation, for example, the prior art patent with publication number CN213997693U provides a cooling device for sand processing equipment. This device puts sand into the feed inlet, turns on motor two, and drives the fan blades to rotate through the operation of motor two. Cold air is drawn in from the outside through the ventilation port, thereby achieving the effect of cooling the sand as it falls from the feed inlet.

[0004] Although the existing technical solution mentioned above uses a motor to drive the fan blades to rotate and draw in cold air through the ventilation opening to cool the sand as it falls from the feed inlet, air cooling mainly relies on air convection and heat conduction for heat dissipation. The heat capacity of air is relatively low, resulting in poor heat dissipation effect of air cooling. Furthermore, heat dissipation during the falling process leads to uneven cooling, affecting the overall efficiency of sand cooling.

[0005] In view of this, we propose a cooling and temperature reduction device for sand processing equipment. Utility Model Content
