Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, and in particular to an air-sealing device for an HMPP prefabricated pump station. Background Technology

[0002] HMPP prefabricated pumping station, short for high modulus polypropylene prefabricated pumping station, is a prefabricated sewage treatment equipment that integrates well shaft, water pump, internal pipeline, valve, liquid level control and other components.

[0003] Utility model patent application publication number 202222395100.1 discloses a gas-isolating device for a prefabricated pumping station, including a housing. The housing contains a mesh plate, with inlets and outlets on both sides of the mesh plate and the side walls of the housing. The housing also contains a partition with multiple through holes. An external gas recovery mechanism is located outside the housing for gas recovery. An internal stirring mechanism promotes the separation of gas and wastewater. When filtering wastewater, this device uses the stirring mechanism to agitate the wastewater, promoting the separation of harmful gases from the wastewater. The separated wastewater is then absorbed by the gas recovery mechanism, thus achieving a gas-isolating effect. This prevents toxic gases from dissolving in impurities or diffusing into the gas stream, protecting workers from potential harm.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when the device is used, it promotes the separation of gas and wastewater by stirring. However, the device contains a large number of metal parts, which are prone to corrosion when immersed in water for a long time, resulting in a reduction in the service life of the device. At the same time, it also uses drive components such as motors, which require additional electricity and frequent maintenance to prevent damage, thus making it impossible to guarantee the service life and reducing the effectiveness of the device.

[0005] Therefore, it is necessary to invent an air-sealing device for HMPP prefabricated pumping stations to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an air-blocking device for HMPP prefabricated pumping stations. By installing a baffle on the inner side of the prefabricated pumping station body, with an air jet and an inner air collection groove on the inner side of the baffle, and an air supply pipe at the top of the baffle connected to the inner air collection groove via a connecting pipe, air can be effectively supplied to inject air into the sewage inside the prefabricated pumping station body. This effectively agitates the sewage, allowing harmful gases to be discharged from the sewage and easily expelled through the exhaust assembly above, thus significantly improving the air-blocking effect. This addresses the problem in the prior art where the aforementioned equipment promotes gas-wastewater separation through agitation, but the equipment contains numerous metal components that are prone to corrosion after prolonged immersion in water, reducing its lifespan. Furthermore, the use of drive components such as motors requires additional electricity and frequent maintenance to prevent damage, further compromising the device's lifespan and reducing its effectiveness.
