The water inlet of the traditional old pumping station adopts a salvage grille decontamination machine. In the design, the rake teeth are used to form a group of continuous working mechanism. Under the transmission of the reduction motor, the rake teeth are driven by the sprocket to run in the working direction. The rake teeth of the horizontal axis clean up the floating and suspended matter in the liquid. When the rake teeth move to the top of the equipment, due to the relative movement between each group of rake teeth due to the guide wheel and the curved rail, most of the rake teeth It falls by gravity, and the other part is brushed by the rotating brush. The fallen grid slag is transported by the screw conveyor for secondary treatment. The salvaged slag is foul-smelling and contains a large amount of sewage, which requires manual transportation and treatment. The work is cumbersome, the cost is high, the working environment is harsh, and there is secondary pollution.

Therefore, the renovation project of the old pumping station urgently needs to solve this problem. The river and sea garbage crushing and pressing integrated machine can be added to the original pumping station without changing the working conditions to crush, squeeze, dehydrate and transport the slag salvaged from the grid. The amount of work will not increase, and it will be greatly compressed. The volume of garbage reduces the workload and changes the working environment. There is no secondary pollution. It is an indispensable product for the transformation of old pumping stations.
