Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 3, in this embodiment, a centrifugal pump with a cleaning device is disclosed, which includes a driving motor 2 and a centrifugal pump case 3 connected together through a transmission shaft 1, the centrifugal pump case 3 is provided with a water inlet 301 and a water outlet 302, one end of the transmission shaft 1 penetrates through the centrifugal pump case 3 and then is in power connection with an impeller 4 located in the centrifugal pump case 3, and the other end of the transmission shaft 1 is in power connection with the driving motor 2. The impeller 4 comprises a wheel disc 401 in power connection with the transmission shaft 1, a plurality of blades 402 are evenly distributed on one side wall of the wheel disc 401 in a circumferential mode, in order to remove impurities on the inner wall of the centrifugal pump shell 3, the tail end of each blade 402 is provided with a notch, a rotatable cleaning roller 403 is arranged in the notch, each cleaning roller 403 comprises a roller body 403-1 and a plurality of bristles arranged on the outer wall of the roller body 403-1, and the roller body 403-1 is connected to the notch through a pin shaft and can rotate. The cleaning roller 403 brushes against the inner wall of the centrifugal pump case 3 during rotation of the vane 402. In addition to this embodiment, the cleaning roller 403 can be replaced with a crushing roller for crushing the impurities in the water.

In order to remove impurities on the impeller 4, a plurality of bristles fixed on the wheel disc 401 are arranged between any two adjacent blades 402.
