[0002] Sewage pumping stations are part of municipal engineering. How to ensure long-term operation of the pumping station after construction is one of the problems that need to be solved. A large amount of garbage or debris is often generated during the operation and maintenance of sewage pipe networks. Traditional sewage grilles are vertical in shape, and the aperture size is controlled to limit large pieces of garbage from entering the pump.

[0003] When the existing sewage pump water inlet grille is in use, since the sewage contains a lot of debris, although some of these debris can be filtered by the grille, a considerable part of them will still enter the sewage pump, which is easy to cause blockage inside the sewage pump and affect the normal use of the sewage pump. After the grille filters some of the debris, it will be troublesome for people to take the grille out of the sewage pipe for cleaning. In order to solve the shortcomings of the existing technology, we propose a debris crushing grille for the water inlet of the sewage pump. Utility Model Content
