Integrated pump station combined grille desilting device and use method thereof

Abstract

The invention relates to an integrated pump station combined grille desilting device and a use method thereof. The integrated pump station combined grille desilting device comprises a pump station cylinder and a submersible sewage pump arranged in the pump station cylinder, a water inlet pipe penetrates through the pump station cylinder, and one end, arranged in the pump station cylinder, of the water inlet pipe is connected with a water inlet filter screen and a trash holding grille; a second grille is arranged in the pump station cylinder, a plurality of water spraying structure branch pipesare arranged in the pump station cylinder below the second grille, the water spraying structure branch pipes are communicated with a water outlet pipeline connected with the submersible sewage pump,openings of the water spraying structure branch pipes face downwards, and control valves are arranged on the water spraying structure branch pipes; a sediment density detector with an alarm is installed at the bottom in the pump station cylinder and connected with the control valves on the water spraying structure branch pipes. Compared with a traditional desilting device, the device focuses on cleaning impurities in incoming flow sewage and impurities deposited at the bottom of a pump station cylinder, and the problem that the impurities in the cylinder cannot be cleaned up is solved.

Description

Technical field [0001] The invention relates to an integrated pump station combined grid dredging device and a use method thereof, and belongs to the technical field of prefabricated pump stations. Background technique [0002] As a new type of pumping station, integrated pumping station has been widely used in water conservancy engineering, municipal engineering and other fields due to its small size, no land occupation index, low manufacturing and installation costs, and convenient maintenance. The main body of the pumping station is mainly composed of cylinder, water pump, grille, hoisting chain, pipeline, valve and other components. Its working principle is mainly as follows: sewage enters the collection tank inside the pump station cylinder through the inlet pipe. According to the continuous rise of the liquid level, the water pump system starts, and the sewage passes through the centrifugal submersible sewage pump, pressure pipe, valve and the outlet pipe in turn. Outflow ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, in order to solve the problem that the impurity particles inside the cylinder body of the integrated pumping station cannot be effectively removed, and to improve a combined grid desilting device for the integrated pumping station and its use method, thereby improving Desilting efficiency, improving self-cleaning effect, reducing costs
