The invention discloses a centrifugal pump used for environment-friendly equipment. The centrifugal pump comprises a centrifugal pump body and a water inlet pond. The water inlet pond is located on one side of the centrifugal pump body. A connecting pipe is fixedly mounted on the side, close to the water inlet pond, of the centrifugal pump body. A water outlet pipe is fixedly mounted on the side,away from the connecting pipe, of the centrifugal pump body. A connecting bend is fixedly mounted on the side, close to the water inlet pond, of the connecting pipe. A water inlet pipe is fixedly mounted at the bottom end of the connecting bend. A water inlet connector is fixedly mounted at the bottom end of the water inlet pipe. A filter net is fixedly mounted on the bottom side of the water inlet connector. A slide groove is formed in the bottom side of the filter net. Two slide blocks are mounted in the slide groove in a sliding mode. The bottom sides of the two slide blocks extend to the outside of the slide groove. The centrifugal pump is simple in structure, two first connecting rods and two second connecting rods move and drive mounting blocks to move, the mounting blocks move to drive bristlebrushes to coat the filter net, the problem that filth on the bottom side of the filter net causes blockage is effectively solved, and the centrifugal pump is convenient to use.
