Sewage pump

Abstract

The invention discloses a sewage pump. The sewage pump comprises a pump shell, wherein an impeller is arranged in the pump shell, and a power shaft is arranged on the right side of the pump shell; anoutlet pipe and an inlet pipe are arranged on the outer side of the pump shell; a first protruding block and a second protruding block are arranged on the portions, on two sides of the inlet pipe, ofthe pump body respectively, a first rotating groove is formed in the first protruding block, and a second rotating groove and a third rotating groove are formed in the second protruding block; the first protruding block and the second protruding block are provided with cover plates covering the first rotating groove, the second rotating groove and the third rotating groove; a first rolling shaft is rotatably connected in the first rotating groove, a second rolling shaft is rotatably connected in the second rotating groove, and a filtering belt penetrating through the third rotating groove andthe inlet pipe is wound between the first rolling shaft and the second rolling shaft; and a cleaning assembly is arranged in the third rotating groove, and a motor is fixedly mounted on the second protruding block. The sewage pump not only is simple in structure, but also can clean the filtering belt automatically.

Description

technical field [0001] The invention belongs to the field of sewage pumps, in particular to a sewage pump. Background technique [0002] The structure of the existing sewage pump includes a motor, an impeller and a pump casing, and a water inlet and a water outlet arranged on the pump casing. The impeller is arranged in the pump casing and connected with the rotating shaft of the motor. The sewage pump needs to install a filter screen at the water inlet. Since the working medium of the sewage pump has more impurities, there will be more impurities on the filter screen over time, which will reduce the water flow in the pipeline and slow down the flow rate, resulting in the working efficiency of the sewage pump. reduce, resulting in air suction, and often need to manually clean the filter, which will waste a lot of manpower and material resources, and will also affect the progress of the project. Contents of the invention [0003] The object of the present invention is to p...

Problems solved by technology

The sewage pump needs to install a filter screen at the water inlet. Since the working medium of the sewage pump has more impurities, there will be more impurities on the filter screen over time, which will reduce the water flow in the pipeline and slow down the flow rate, resulting in the working efficiency of the sewage pump. Reduced, air suction phenomenon occurs, and the filter screen is often cleaned manually, which will waste a lot of manpower and material resources, and will also affect the progress of the project
