Two-way crushing cylinder

Abstract

The invention discloses a two-way crushing cylinder, comprising a crushing cylinder body for crushing solid impurities in sewage, the upper end of the crushing cylinder body communicates with a water inlet pipe, and the lower end of the crushing cylinder body communicates with a sewage pump through a drainage pipe The middle part of the crushing cylinder is provided with a through installation hole. The middle wall of the crushing cylinder at the installation hole divides the inner space of the cylinder into a left area and a right area. The top of the installation hole is facing the water inlet pipe. In the middle of the water inlet, a shunt crushing motor is fixedly installed on the middle wall of the crushing cylinder at the installation hole, the output shaft of the shunt crushing motor extends vertically upwards and passes through the middle wall, and the output shaft of the shunt crushing motor is installed There is a split flow crushing cutter head, and the split flow crushing cutter head is facing the water inlet of the water inlet pipe. The large-diameter polymerized solid debris is crushed by the shunt crushing motor for the first round, and then flows down through the left and right areas after crushing, the effect of impurity crushing is good, and the efficiency of shunting and sewage discharge is higher.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a bidirectional crushing cylinder used for a sewage lifter. Background technique [0002] The sewage riser is a kind of drainage equipment, which is used in basements, ships, vehicles and other places far away from the drainage standpipe and where the drainage conditions are not good. It can collect and treat domestic water in the bathroom. It is usually an overall system that can solve public health problems in some special places. The automatic sewage lifter can be mainly used for the discharge of sewage from sanitary ware in basements and places far away from drainage risers that do not have self-flowing sewage, and can also be used in places with poor drainage conditions such as ships and vehicles. [0003] However, there are generally solid substances such as feces in sewage, which need to be crushed by using a sewage lifter. The common crushing mechanisms ...

Problems solved by technology

[0003] However, there are generally solid substances such as feces in the sewage, which need to be crushed with a sewage lifter. Common crushing mechanisms are single-directional crushing devices, and the crushing efficiency needs to be improved.
