Sewage anti-blockage machine

Abstract

The invention provides a sewage anti-blockage machine which comprises a filter bin and a backwashing bin communicated with the bottom surface of the filter bin, wherein a sewage inlet and a filtering water outlet are formed in the side wall of the filter bin; the horizontal position of a filter plate is arranged between the sewage inlet and the filtering water outlet; a through hole is formed in the center of the filter plate; a device for collecting and discharging impurities passes through the through hole and is vertically arranged in the filter bin; the device for collecting and discharging impurities comprises a water resistance part, a lower connecting rod and a plug which are sequentially connected from top to bottom; the lower end of the water resistance part is connected with a cylindrical filter screen which does not have a lower bottom wall; the size of the plug is matched with that of a communicating hole between the filter bin and the backwashing bin; the device for collecting and discharging impurities enters the backwashing bin through the communicating hole; the filtered water is used by a hot pump, the return water of the hot pump is used for carrying out backwashing on the inner wall of the filter screen, and the device for collecting and discharging impurities is reset to the initial position after backwashing. The sewage anti-blockage machine is simple in structure, is capable of collecting and discharging the impurities while guaranteeing the filter area and the filter efficiency, and is capable of continuously working.

Description

technical field [0001] The invention relates to the field of sewage filtration, in particular to a sewage anti-blocking machine. Background technique [0002] Sewage reuse technology has been widely used in recent years, but the sewage contains a lot of impurities. Some equipment (such as heat pumps) need to filter the sewage before use. Need to stop related equipment to remove impurities on the surface of the filter device or replace the filter equipment, which is quite troublesome for equipment that needs to work continuously. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a sewage anti-blocking machine that has a simple structure, can collect and discharge impurities while ensuring the filtration area and filtration efficiency, and can work continuously. [0004] In order to achieve the above object, the present invention provides a sewage anti-blocking machine, comprising a cylindrical...
