Desilting method for prefabricated pump station

Abstract

The invention discloses a desilting method for a prefabricated pump station, and particularly relates to a desilting device for the prefabricated pump station. The desilting device comprises a base connected with a pump, four desilting channels formed in the base, a slope guide structure connected with the four desilting channels, and a material passing structure used for preventing the desilting channels from being blocked, wherein the slope guide structure is fixed to the base and communicates with the four desilting channels; one end of the material passing structure is arranged in the four desilting channels, and the other end of the material passing structure is located outside the base; and silt in sewage slides downwards to a large liquid guide groove and a small liquid guide groove on the face according to the action of gravity and is guided to flow in the direction of a liquid discharging hole, discharging and fixing are conducted, a piston rod contracts towards the interior of an air box, the lower portion of the liquid discharging hole is blocked through a filter barrel, solid impurities are pushed to move towards a solid discharging hole in the moving process till the solid impurities retreat out of an outer ring, filtering of particle impurities is completed, and blockage caused by excessive accumulation is avoided.

Description

technical field [0001] The invention relates to the field of dredging, in particular to a dredging method for a prefabricated pump station. Background technique [0002] The integrated prefabricated pumping station is widely used in many fields such as tap water source water intake, sewage, rainwater, industrial wastewater transportation, etc. Due to the complex composition of the source water, it contains various particles, rags, paper products, wood products, rubber products, plastic products and various soft products, among which a considerable part of the heavier particles enters the cylinder with the incoming water and settles to The bottom of the cylinder is not easily discharged by the water pump. [0003] The base of the traditional pumping station uses a flat base, and there is a large gap between the pump and the base, which cannot quickly pump sewage, and the flat base is easy to accumulate silt and water, which affects the efficiency of the pump; sewage particle...
