Circulating water filtering device for geothermal energy

The utility model discloses a circulating water filtering device for geothermal energy, which comprises a shell box, a water outlet pipe is arranged at the lower end of one side of the shell box, a filtering box is fixedly connected to the center of the inner wall of the shell box, and a plurality of through holes are formed in the two ends of the filtering box in a penetrating manner; the geothermal water filtering device has the advantages that the filtering frame is driven to ascend and descend through the second sliding groove and the sliding block, rapid dismounting is achieved, impurities are cleaned away after geothermal water is filtered, under the interaction of the reciprocating lead screw and the lead screw nut, the filtering effect is good, and the service life of the geothermal water filtering device is prolonged. By matching with rotation of fan blades, a water source can be further driven to rotate, a mixing box is matched for filtering, a filtering frame and a filtering box are used for interc
