Simple maintenance-free sewage lifting device

Abstract

The invention discloses a simple maintenance-free sewage lifting device which comprises a water collection tank. A lifting regulation valve is arranged on the lateral surface of the water collection tank; the lifting regulation valve is connected with the water collection tank by a flexible check valve; a liquid storage device is arranged in the water collection tank; the liquid storage device is fixed in the water collection tank; a sewage buffer pipe is transversely arranged on the liquid storage device; one end of the sewage buffer pipe is connected with a float valve; one end of the float valve is connected with the sewage buffer pipe; the other end of the float valve is fixed on the inner wall of the water collection tank; a compression tube is arranged on the lower surface of the float valve; the compression tube is sleeved with the float valve. The simple maintenance-free sewage lifting device not only can drain sewage, but also can prevent the sewage from flowing back, can achieve the effects of no maintenance and no cleaning, realizes long-term effective safety operation, can better meet the design and use requirements of an underground bathroom, has a compact structure, works stably and has obvious application value.

Description

technical field [0001] The invention relates to a lifting device, in particular to a simple maintenance-free sewage lifting device. Background technique [0002] The continuous exaggeration and construction of the city makes the urban land increasingly tense, which forces people to continue to develop underground, and the subsequent drainage problem of underground buildings also brings great difficulties to people. Sewage pumps are used to treat underground sewage. This method has a high failure rate and is no longer suitable for the needs of modern life. In modern architectural design, building a bathroom in the basement of a building is often encountered in the process of design. One method is to collect the sewage from sanitary ware and then use a submersible pump to lift it to the outdoor basement sewage pump well. The method is to automatically discharge the sewage in the toilet into the outdoor underground sewage pump well. There is a disadvantage in these two types o...

Problems solved by technology

[0002] The continuous exaggeration and construction of the city makes the urban land increasingly tense, which forces people to continue to develop underground, and the subsequent drainage problem of underground buildings also brings great difficulties to people. Sewage pumps are used to treat underground sewage. This method has a high failure rate and is no longer suitable for the needs of modern life.

In modern architectural design, building a bathroom in the basement of a building is often encountered in the process of design. One method is to collect the sewage from sanitary ware and then use a submersible pump to lift it to the outdoor basement sewage pump well. The method is to automatically discharge the sewage from the toilet into the outdoor underground sewage pump well. Both of these two methods have a disadvantage, and they cannot better improve the sewage treatment.
