Description

TECHNICAL FIELD

[0002] The pump station is a device that can increase the pressure of low-pressure fluid, and the integrated prefabricated pump station has the advantages of small volume and high automation, and has been widely used in the discharge and transfer of urban sewage and industrial wastewater. Due to the reasons of space closure of the integrated pump station and sewage as the transportation medium, there are two problems, one is that the toxic and harmful gases are easy to accumulate in the pump station, which threatens the maintenance personnel, and the other is that the pump station is easy to be blocked, which affects the normal operation of the pump station.

[0003] The prior art discloses a pump station cylinder with waste gas purification function, which provides a filtering and burning device, and the purpose is to burn and discharge the harmful gas in the integrated pump station. This scheme has the disadvantages of high cost and easy accidents in the combustion process. Moreover, the harmful gas generated in the integrated pump station is not much, and can be degraded by the self-cleaning ability of the environment. The prior art discloses an air inlet and outlet structure for effectively removing harmful gas. The device uses an air inlet device to automatically discharge the harmful gas in the pump station. However, the air inlet device often has a motor, and when the flammable gas in the pump station exceeds the standard, the risk of flash explosion is easy to occur. For the blocking problem of the integrated pump station, the prior art discloses an integrated lifting pump station with a anti-blocking monitoring mechanism. This scheme uses a pulverizer and a grid to avoid blockage. However, the sediment and impurities in the sewage will gradually deposit at the bottom of the pump station. When a large amount of sediment is sucked into the water pump at the same time, the risk of blockage still exists. SUMMARY
