AI Technical Summary

Technical Problem

Traditional sewage pumps have complex filtration structures, are difficult to maintain, are prone to corrosion, and have unstable filtration effects, allowing impurities to easily enter the pump body and cause damage.

Method used

A sewage pump with a built-in filter structure was designed. It adopts a filter installation mechanism with a sliding groove and a slider, and is fixed with a screw, which facilitates the installation and replacement of the filter disc. The cleaning mechanism drives the rotating shaft through the impeller assembly to achieve real-time cleaning of the filter disc.

Benefits of technology

It improves filtration efficiency, simplifies the maintenance of the filter disc, prevents impurities from entering the pump body, and extends the service life of the equipment.
