Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to an anti-blocking device for sewage pumps. Background Art

[0002] Sewage pumps are often used to transport urban sewage, and sewage often contains some entangled or bunched fibers or a large amount of mud, so the flow channel of this type of pump is easy to be blocked. Once the pump is blocked, the pump will not work properly or even burn the motor, resulting in poor sewage discharge, which has a serious impact on urban life and environmental protection. Existing sewage pumps often have a filter at the water inlet of the sewage pump to prevent the influx of foreign matter, but silt, entangled or bunched fibers are easy to stick to or entangle on the filter, so that the filter is blocked, which also causes the sewage pump to fail to work properly.
