Embodiment 1

[0026] see Figure 1-4 , an embodiment provided by the present invention: an anti-clogging water pump for sewage treatment and transportation, comprising a centrifugal pump body 1, a base 11 is provided at the lower end of the centrifugal pump body 1, and a pump with an impeller inside is fixedly installed in the middle of the base 11 Body 12, one side of the pump body 12 is provided with a motor fixedly installed on the base 11 and used to drive the impeller, the motor is a three-phase asynchronous motor commonly used in centrifugal pumps on the market, and also includes a filter device 2, which is fixedly installed On the other side of the pump body 12, the filter device 2 includes a filter water inlet 21 on the upper end, a filter water outlet 22 on one side, a flush water end 23 installed on the outside of the filter water inlet 21 pipeline, and a filter water outlet 23 on the other side. The sewage discharge end 24 on one side and the filter screen 201 installed inside, t...

Embodiment 2

[0034] see Figure 5 , an embodiment provided by the present invention: the difference from Embodiment 1 is that the center lines of the filter water outlet 22, the water inlet end of the pump body 12, the shaft of the impeller and the shaft of the motor are all collinear, and the filter water inlet The pipeline at end 21 is perpendicular to the pipeline at filter water outlet 22, the centerlines of the pipeline at filter water inlet 21, the pipeline at filter water outlet 22, the pipeline at flush water end 23, and the pipeline at sewage discharge end 24 are all in the same plane, and the pipeline at the flush water end The 23 pipeline is perpendicular to the filter screen 201, which is more convenient to flush the filter screen 201. The angle between the sewage discharge end 24 pipeline and the filter water inlet 21 pipeline is greater than 90 degrees, and the sewage discharge end 24 pipeline and the filter water outlet 22 pipeline The angle between them is greater than 90 d...

Abstract

The invention discloses an anti-clogging water pump for sewage treatment and transportation, relates to the structural field of centrifugal pumps, and solves the complicated problem that pipe fittings need to be removed for regular cleaning of the anti-clogging filter device of the sewage treatment pump. The invention includes a centrifugal pump body and a filter device, the filter device is fixedly installed on one side of the pump body, the filter device includes a filter water inlet end, a filter water outlet end, a flushing water end, a sewage discharge end and a filter screen, the filter water inlet end pipeline and The pipes at the filtered water outlet intersect, the pipes at the filtered water outlet are connected to the water inlet of the pump body, the pipes at the sewage discharge end intersect with the pipes at the filtered water inlet, the pipes at the sewage discharge end intersect with the pipes at the filtered water outlet, and the edge of the filter screen Completely cut off the connection between the filtered water inlet and the filtered water outlet. The invention can filter the sewage through the filter screen, and the filter screen can be cleaned simply and conveniently through the flushing end and the sewage discharge end.

Description

technical field [0001] The invention relates to the structural field of centrifugal pumps, in particular to an anti-clogging water pump for sewage treatment and transportation. Background technique [0002] Sewage treatment pumps mostly use cantilever single-stage single-suction centrifugal pumps, which are pumps that transport liquids by the centrifugal force generated when the impeller rotates. Centrifugal pumps are mainly composed of impellers, pump bodies, pump shafts, seals and motors. Partially composed. [0003] At present, the sewage treatment pump is used to transport sewage, and the sewage contains a lot of impurities, which is easy to cause blockage. In order to prevent the sewage treatment pump from being blocked, a type of crushing centrifugal pump has appeared on the market, that is, a knife set is installed at the front end of the impeller for Cutting sundries, but this is not only easy to damage, but also makes a lot of noise, and the small and hard sundries...
