[0002] Construction sand and gravel need to be cleaned before use. The existing method is to add production raw materials and circulating water into the raw material pool at the same time for stirring, and then screen and separate the sand and gravel. The sand and gravel enter the next process of the production line, and the mud water enters the sewage pool. The mud water is transported through the pipeline by the slurry pump.

The clean water has a height difference in the process of entering the clean water pool, and there will be potential energy. However, the existing production system does not convert the potential energy in the water recovery process, resulting in energy loss. Utility Model Content
