Sewage pump with self-cleaning function

Abstract

The invention discloses a sewage pump with the self-cleaning function. The pump comprises a pump body, a filter plate, smashing wheels and scraping plates, a buffer cavity is formed in a water inlet of the pump body, the filter plate is fixedly arranged at the position, close to the water inlet, in the buffer cavity, first moving grooves are formed in the positions, below the filter plate, of thefront inner wall and the back inner wall of the buffer cavity, the symmetric scraping plates are arranged in the moving grooves in a sliding manner, the scraping plates are tightly attached to the filter plate, a first motor and a synchronous wheel are fixed to the two sides of each first moving groove, the output ends of the first motors are fixedly provided with the synchronous wheels which areconnected through a synchronous belt, the scraping plates are fixedly connected with the upper and the lower of the synchronous belt, second moving grooves are formed in the positions, below the firstmoving grooves, of the front and rear inner walls of the buffer cavity, second motors are symmetrically arranged in the second moving grooves in a sliding manner, the output ends of the second motorsare fixedly provided with rotating shafts, the rotating shafts are fixedly provided with the smashing wheels, and shaft sleeves are arranged at the positions, on the two sides of the smashing wheels,of the rotating shafts.

Description

technical field [0001] The invention relates to a sewage pump with self-cleaning function, which belongs to the technical field of sewage pump equipment. Background technique [0002] The sewage pump is a kind of pump connected with the motor and submerged into the liquid to work at the same time. The liquid for farmland irrigation or sewage treatment often contains a large amount of impurities, resulting in a large amount of impurities remaining in the pump body after the sewage pump is finished. Residue, the traditional sewage pump does not have automatic cleaning work, and often requires staff to clean up, which is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide a sewage pump with self-cleaning function to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a sewage pump w...
