AI Technical Summary
During use, the filter screen of the existing sewage pump is prone to clogging, which leads to a decrease in sewage discharge efficiency, requires manual cleaning, and affects the operation of the equipment.
Design a filter cleaning mechanism that uses sewage discharged by the sewage pump to flush the filter surface through a flushing pipe and nozzle, removing attached foreign matter and keeping the filter unobstructed.
It effectively reduces filter clogging, improves the sewage pump's discharge efficiency, reduces equipment energy consumption, and minimizes manual intervention.

Abstract
Claims
1. An anti-clogging structure for a sewage pump, comprising: The main body of the sewage pump (1) is provided with a drive motor and an impeller, and the bottom of the main body of the sewage pump (1) is provided with a suction port (2); A filter screen (3) is disposed in the inlet (2); Discharge pipe (4), which is provided on one side of the sewage pump body (1) for discharging sewage; Its characteristic is that it further includes: A filter screen (3) cleaning mechanism is provided on the discharge pipe (4); The filter screen (3) cleaning mechanism guides the sewage in the discharge pipe (4) back to the suction port (2) and washes the surface of the filter screen (3) during the process of the sewage pump discharging sewage.
2. The anti-clogging structure of a sewage pump according to claim 1, characterized in that, The filter (3) cleaning mechanism also includes: A flushing pipe (50) is provided, one end of which is connected to a discharge pipe (4) for introducing a portion of the discharged wastewater as flushing water. Nozzle (51), the nozzle (51) is disposed on one side of the inlet (2), the nozzle (51) is connected to the flushing pipe (50) to receive flushing water introduced in the flushing pipe (50) and spray the flushing water onto the surface of the filter screen (3); A control valve (52) is connected in series on the flushing pipe (50) to control the opening and closing of the flushing pipe (50).
3. The anti-clogging structure of a sewage pump according to claim 2, characterized in that, The nozzle (51) further includes: A horizontal flow divider (510) is provided at the outlet of the nozzle (51) at any time. The horizontal flow divider (510) extends horizontally along the width direction of the nozzle (51). A vertical flow divider (511) is disposed in the nozzle (51). The vertical flow divider (511) extends along the length direction of the nozzle (51) and is in the shape of a zigzag plate.
4. The anti-clogging structure of a sewage pump according to claim 3, characterized in that: The height of the nozzle (51) changes along the spray direction of the nozzle (51) in a decreasing-increasing-decreasing trend.
5. The anti-clogging structure of a sewage pump according to claim 4, characterized in that: The filter screen (3) is arranged at an angle.
