Cut-up type blow-down pump

Abstract

Aiming at the defect of easy blow-down pump winding in the prior art, the invention discloses a cut-up type blow-down pump which can effectively cut long fibers and is not easily blocked. The cut-up type blow-down pump comprises a pump body, a motor, an impeller arranged in the pump body and a motor shaft connected with the motor and the impeller. The motor shaft is sheathed by a bush. The pump body is formed by fixedly connecting a base, a front cover and a rear cover. The impeller is arranged between the front cover and the rear cover. The body of the front cover is provided with a materialinlet through which materials can enter. A surface position of the front cover, which is positioned in the pump body, is provided with a front cover stationary cutter which is cooperated with the impeller during cutting. The base is provided with a material outlet through which materials can be discharged. The material inlet takes the shape of heart.

Description

technical field [0001] The invention relates to a chopping sewage pump, in particular to a chopping sewage pump for removing feces containing long fibers. Background technique [0002] The Chinese utility model patent named "chopped sewage pump", the patent number is ZL200420082659.8, the authorized announcement date is October 19, 2005, and the authorized announcement number is CN2735052Y discloses a chopped sewage pump, which includes The pump body, the submersible motor, the impeller placed on the motor shaft and the front pump cover, the head of the impeller is equipped with more than two protruding movable blades, and the front pump cover is equipped with more than two uniformly distributed fixed blades. When the chopping sewage pump is working, when the long fiber enters the pump inlet, under the action of centrifugal force, it moves from the center to the outside, and enters between the movable blades rotating at high speed, thereby cutting the long fiber, but because...

[0002] The Chinese utility model patent named "chopped sewage pump", the patent number is ZL200420082659.8, the authorized announcement date is October 19, 2005, and the authorized announcement number is CN2735052Y discloses a chopped sewage pump, which includes The pump body, the submersible motor, the impeller placed on the motor shaft and the front pump cover, the head of the impeller is equipped with more than two protruding movable blades, and the front pump cover is equipped with more than two uniformly distributed fixed blades. When the chopping sewage pump is working, when the long fiber enters the pump inlet, under the action of centrifugal force, it moves from the center to the outside, and enters between the movable blades rotating at high speed, thereby cutting the long fiber, but because the long fiber passes through The inlet is very smooth when entering, so it is easy to block the sewage pump
