Filtering and self-collecting type submersible sewage pump

Abstract

The invention belongs to the technical field of pumps, and particularly relates to a filtering and self-collecting type submersible sewage pump which comprises a centrifugal pump, a shell and a filtering part. According to the filtering and self-collecting type submersible sewage pump, the centrifugal pump works, sewage in the shell is sucked into the centrifugal pump through the filtering part, large particles are blocked below by a horn mouth structure, the particles blocked below the horn mouth structure move upwards along the surface of the horn mouth structure under the action of water flow, then the particles enter a collecting structure, and the filtered sewage is discharged by the centrifugal pump, so that the sewage is conveyed; and most of conventional sewage pumps are internally provided with crushing mechanisms, when particles are hard and cannot be crushed or more particles enter, the particles can hinder rotation of an impeller, normal work of the sewage pump is affected, and the submersible sewage pump separates the particles from sewage, so that the situation that rotation of the impeller of the centrifugal pump is hindered by the particles is avoided, then stable work of the centrifugal pump is achieved, and then stable work of the submersible sewage pump is achieved.

Description

technical field [0001] The invention belongs to the technical field of pumps, in particular to a filtering self-collecting submersible sewage pump. Background technique [0002] The sewage pump is a kind of centrifugal impurity pump. The sewage pump can not only need to install the bottom valve and irrigation water like the general self-priming clean water pump, but also can absorb and discharge the liquid containing large solid particles and long fiber impurities. It can be widely used in municipal sewage projects In industries such as river and pond farming, sewage pumps have the characteristics of being able to transport liquids containing hard solids and fibers, as well as particularly dirty, sticky and slippery liquids, and are widely used in sewage treatment in various fields. [0003] Most of the conventional sewage pumps are equipped with a crushing mechanism in the sewage pump to crush larger particles. When the particles are too hard to be crushed or too many parti...

AI Technical Summary

Problems solved by technology

The present invention is mainly used to solve the problem that most of the conventional sewage pumps are equipped with a crushing mechanism in the sewage pump. When the particles are relatively hard and cannot be broken or too many particles enter, the rotation of the impeller will be hindered and the normal operation of the sewage pump will be affected.
