The invention has the working principle that impurities in materials are filtered through the first filter screen plate 7, meanwhile, when the first filter screen plate 7 is blocked, the transmission mechanism drives the transmission tube 6 and the first filter screen plate 7 to rotate, and meanwhile, the first filter screen plate 7 is self-cleaned by matching with the filter box and the second filter screen plate 14, so that the materials entering the centrifugal pump are filtered, and meanwhile, the filtered impurities are self-cleaned under the condition that the centrifugal pump is not stopped, so that the working stability of the centrifugal pump is greatly improved.
The transmission pipe 6 is supplied with liquid through the water inlet pipe, then the transmission pipe 6 washes the centrifugal pump impeller through the cleaning pipe 41 and the cleaning spray head 42, chemical agents are introduced into the second connecting pipe 51 and the transmission pipe 6 through the pump body 52 and the pipeline, and then the transmission pipe 6 washes and cleans the surface of the centrifugal pump impeller 8 through the cleaning pipe 41 and the cleaning spray head 42, so that the centrifugal pump impeller 8 is comprehensively self-cleaned.
The transmission rod 63 is driven to move through the electric telescopic rod 68, the transmission rod 63 drives the connecting plate 64 and the electromagnetic iron plate 65 to move, the electromagnetic iron plate 65 drives the second cleaning hairbrush 67 to clean the side face of the centrifugal pump impeller, meanwhile, the permanent magnet iron plate 66 is adsorbed on the surface of the centrifugal pump impeller 8, and then the permanent magnet iron plate 66 and the second cleaning hairbrush 67 are driven to rotate through the centrifugal pump impeller 8 to clean the inner surface of the centrifugal pump housing 3 comprehensively, so that the inner surface of the centrifugal pump housing 3 and the side face dirt of the centrifugal pump impeller 8 are cleaned comprehensively, the influence of the dirt on the centrifugal pump is reduced, and the working stability of the centrifugal pump is improved.
The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
