Efficient sewage pumping station constructed by municipality

Abstract

The invention relates to an efficient sewage pumping station constructed by a municipality. The efficient sewage pumping station comprises a main body, a first underground wall body, a water inlet pipe, a first electric valve, a cutting pump, a first liquid level alarm, a second liquid level alarm, a third liquid level alarm, a main pump, an auxiliary pump, a second underground wall body, a main pump coupling device, an auxiliary pump coupling device, a second electric valve, a drain pipe, a control cabinet, a biogas generator, a biogas collection tank, a first warehouse body, a second warehouse body and the ground. According to the efficient sewage pumping station, a liquid level alarm is installed to monitor the liquid level of sewage, and the liquid level is fed back to the control cabinet; when the liquid level is very low, a pump is stopped and water is stored; when the liquid level reaches the pump starting liquid level, the main pump starts to work; when the liquid level is very high, the auxiliary pump starts to work together, thus the efficient discharge of the sewage is realized. Bamboo charcoal sound insulation cotton is arranged, on the one hand the noise generated during the work of a motor is absorbed, and uncollected odor gas is absorbed and used well. The power can be re-supplied when the system is powered down, and the back-up energy is provided for the system.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a high-efficiency sewage lifting pump station for municipal construction. Background technique [0002] In today's society, for large and medium-sized cities, due to the large area of ​​sewage to be treated, sewage treatment plants have been built to achieve sewage treatment in a centralized manner. The centralized treatment of sewage needs to centrally transport the large area of ​​sewage discharged to the sewage treatment plant. In the process of sewage transportation, due to the long distance, the sewage pipes are buried very deep underground. A pumping station is set in the middle of the project, and the sewage is lifted and then transported to a further place through the sewage pipeline. This pumping station is the sewage lifting station. The role of the sewage lifting station is to lift the distant sewage to the sewage treatment plant for centralized treatme...

AI Technical Summary

Problems solved by technology

Since the sewage pump has been operating in a harsh environment in contact with sewage for a long time, the service life of the sewage pump has been reduced. At the same time, because it is fixed in the sump through a coupling device, the installation is cumbersome, and the maintenance cost is high and inconvenient.

[0004] Existing sewage lifting pump stations usually have a relatively simple structure and relatively single function. The gas generated by the sewage is generally sealed. During the maintenance and repair process, the odor gas enters the process of manual maintenance, which greatly increases the work difficulty. At the same time, once the system fails to provide power, the foreign matter in the sewage cannot be crushed and cut, and the water in the system cannot be discharged. In addition, the existing technology cannot start and stop the pump according to the liquid level. The degree of intelligence At the same time, in winter, the weather is very cold and the sewage freezes, which greatly reduces the working efficiency of the sewage pumping station
