Abstract

The invention belongs to the technical field of pumps, and particularly relates to a submersible sewage pump. The submersible sewage pump comprises a pump body, a first impeller, a second impeller, a rotating shaft and a crushing part. The first impeller, the crushing part and the second impeller are driven by the rotating shaft to synchronously rotate at a high speed, when the first impeller rotates, sewage in a crushing cavity and a suction cavity is sucked into a discharge cavity, then the sewage enters a sewage discharge pipeline, when the second impeller rotates, the second impeller generates acting force on the sewage between blades, then the sewage in the suction cavity enters the crushing cavity, sewage in a sewage pool is discharged into the sewage discharge pipeline under the combined action of the first impeller and the second impeller, and then sewage conveying is realized; and the crushing part is arranged on the first impeller and the second impeller to crush large-size sundries, then the sewage has a very high flowing speed when the crushing part crushes the sundries, then the influence of the sundries on the flowing speed of the sewage is reduced, and then the sewage discharge efficiency of the sewage pump is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pumps, in particular to a submersible sewage pump. Background technique [0002] Sewage pump is a kind of centrifugal pump, which can transport liquids containing hard solid particles, fibers and other impurities, as well as thick liquids, and even sludge. It has the characteristics of strong transport capacity and fast transport speed, and is widely used. In various fields of sewage treatment. [0003] Most of the existing sewage pumps are equipped with a crushing mechanism at the inlet of the sewage pump to prevent debris from entering the sewage pump and crushing outside the sewage pump. Before the debris is broken, it will hinder the sewage from entering the sewage pump and reduce the speed of sewage entering the sewage pump. , which affects the sewage discharge efficiency of the sewage pump. Contents of the invention [0004] In order to make up for the deficiencies of the prior art, the inventio...
