The top of the water circulation device body is provided with a water trap, and the bottom of the water circulation device body is fixedly installed with a mobile platform. The top of the mobile platform is provided with an inclined support column. The interior of the water circulation device body is provided with a water source filter layer, and the water source filter layer is used to filter and clean the water source for beneficiation".
