Sewage lifting device provided with seal structure

Abstract

The invention discloses a sewage lifting device provided with a seal structure, which comprises a water collecting header; a lift-control valve, which is connected to the water collecting header by a flexible check valve , is arranged on a side face of the water collecting header; a liquid storage device provided with a sewage buffer tube in a lateral direction is arranged in the water collecting header in a fixing way; one end of the sewage buffer tube is connected with a floating valve; one end of the floating valve is connected with the sewage buffer tube, the other end of the floating valve is fixed on the inner wall of the water collecting header, and a lower surface of the floating valve is provided with a pressure tube, which is connected in the floating valve in a sleeving way. The sewage lifting device provided with the seal structure is capable of discharging sewage and preventing reverse flow of sewage, and the device is maintenance-free, cleaning-free, effective in long term, safe in operation, compact in structure, and stable in work, can better meet design and use requirements of an underground bathroom and has significant application value.

Description

technical field [0001] The invention relates to a lifting device, in particular to a sewage lifting device provided with a sealing structure. 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 t...

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.
