Technical field

The present invention relates to the technical field of integrated pumping stations, and more specifically, to an integrated sewage lifting pumping station.

Background technique

Sewage treatment plants generally use gravity flow to pass through various structures and equipment during the operation process. However, due to the limitations of the terrain and geology of the factory area. A lifting pump station must be added at the pre-treatment area to lift the sewage to a certain height before it can be operated according to the gravity flow method. The function of the sewage lifting pumping station is to lift the sewage from the upstream to the height required by the subsequent treatment unit so that it can achieve gravity flow. Lifting pump stations generally consist of water pumps, collection tanks and pump rooms. In the integrated sewage lifting pumping station in the existing technology, under normal circumstances, the sewage at the bottom of the pumping station cannot be drained cleanly, and there is a certain amount of accumulated water, impurities, dirt, sludge, etc. The impurities, dirt, sludge and accumulated water When water does not flow for a long time, it is easy to turn black, smelly, rot and produce harmful gases, and it is easy to breed mosquitoes and other pests. It has a negative impact on the surrounding people and livestock. Therefore, how to clean the accumulated water, impurities and sludge in the integrated sewage lifting pump in a timely manner is an urgent problem that needs to be solved.

Embodiment 3: Referring to Figures 6 to 8, this embodiment is structurally similar to Embodiment 2. The difference is that a liquid guide hole 44 is provided in the center of the liquid separator 4, and the bottom of the liquid separator 4 is in contact with the bottom of the pump. A dirt-containing cavity 21 is formed between 2, and the rotating shaft 5 extends through the liquid guide hole 44 to the dirt-containing cavity 21.
