Abstract

The invention relates to the technical field of environmental protection equipment, and discloses a sewage lifting system, comprising a water intake pipe connected to a sump, the water intake pipe is fixedly connected with a separation pipe with a filter screen, and the separation pipe is far away from one end of the water intake pipe The sewage pump is connected through the connecting pipe, and the other end of the separation pipe is connected with the collecting pipe. The sewage lifting system separates the large garbage in the sewage first, and the filtered sewage is accelerated by the sewage pump and then collected to drive the large garbage to be discharged, reducing the damage to the blades of the sewage pump caused by the large garbage, and at the same time enhancing the ability to discharge large garbage. Reduce the accumulation of large garbage. Secondly, the water hammer phenomenon is used for secondary pressurization, which improves the lifting capacity of the system. In the discharge stage, large garbage is directly collected and discharged with high-pressure and high-speed sewage, which shortens the length of the process in which large garbage participates. , reduce the number of turns of large garbage, further reduce flow resistance and energy consumption, and improve the efficiency of power equipment.

Description

technical field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a sewage lifting system. Background technique

[0002] Most of the basement drainage in China is to design a cement brick sump in the basement, and the toilet sewage, bathroom sewage and washbasin sewage are discharged into the sump through the same layer of pipes. Install two submersible pumps in the water pit, which is what we usually call "one pit with two pumps" underground sewage discharge method.

[0003] Although the double pumps work alternately to ensure the reliability of sewage discharge. However, because the composition of the sewage is too complex and contains a lot of large impurities, it is easy to cause the submersible pump to be blocked or damaged. Although most of the problems can be solved by adding a filter screen and a rotating cutting head, on the one hand, the long-term After use, there is a phenomenon that the filter screen is ...
