Technical Field

[0001] The utility model relates to the technical field of pump stations, in particular to a multifunctional sewage treatment pump station. Background Art

[0002] At present, in the process of sewage treatment, pump stations are generally used to transport and transfer sewage. However, sewage contains a large amount of particulate matter, which will damage the water pump when entering the pump station. Therefore, the existing technology generally uses a filtering device to filter the sewage entering the water pump. However, the filtering device will quickly accumulate a lot of particulate matter, and the mesh on the filtering device will quickly become clogged, so the water pump needs to stop working. At this time, the transportation and transfer of sewage will be delayed, and the staff need to enter the pump station to clean the filtering device. In addition, the water pump in the pump station makes a lot of noise when working. Utility Model Content

When cleaning the anti-blocking filter mechanism, it can ensure that one of the water pumps maintains a working state, and will not delay the transportation and transfer of sewage. The staff does not need to enter the pump station to open and clean the anti-blocking filter mechanism. The annular filter screen in the anti-blocking filter mechanism is easy to clean, and a sound insulation board is provided to reduce the noise spreading outward from the pump station, which can effectively solve the problems in the background technology.
