Problems solved by technology

However, there is a defect in the use of the gas lift pipe, that is, when the sewage liquid level line of the sewage to be lifted in the sewage pool is low, and the lift required to lift the sewage is high, the gas lift pipe cannot lift the sewage up, because a single The maximum head of the gas riser is 1.5 times the height of the liquid level line of the sewage to be lifted in the sewage tank. If it exceeds this range, the gas riser will not be able to complete the lifting of the sewage

Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0017] Such as figure 1 As shown, a sewage lifting device includes an air source, a first gas lift pipe 100 , and a sewage multi-stage lifting structure 200 for multi-stage lifting of the sewage output by the first gas lift pipe 100 . The gas source supplies gas to the first gas riser 100 .

[0018] The sewage multi-stage lifting structure 200 is composed of a plurality of single-stage sewage lifting parts 210; when setting, according to specific needs, the number of single-stage sewage lifting parts 210 can be one, two, three, four, five, six Wait a minute. All single-stage sewage lifting parts 210 are matched and connected in turn to form multi-stage lifting; each single-stage sewage lifting part 210 is composed...

Abstract

The invention relates to sewage lifting equipment. The sewage lifting equipment comprises a gas source, a first gas lifting pipe and a sewage multistage lifting structure used for conducting multistage lifting on sewage output by the first gas lifting pipe; the sewage multistage lifting structure is composed of multiple single-stage sewage lifting members; the single-stage sewage lifting members are sequentially connected in a matched mode to form multistage lifting. The sewage lifting equipment has the advantages that when the required sewage lifting height is 1.5 times larger than the height of the liquid level line of to-be-lifted sewage in a sewage tank, lifting can still be conducted; meanwhile, the gas source is only used as power in the whole equipment, the whole structure of the sewage lifting equipment is simplified, use of other equipment is reduced, and the energy is saved; in the sewage lifting process, the lifting flow of the sewage can be changed by adjusting the gas supply quantity of the gas source, and therefore the situation that due to the fact that the flow is too large, the next sewage treatment process is affected is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage lifting device. Background technique [0002] At present, pumps are used for lifting sewage in sewage treatment equipment, and it is difficult to find a pump with a suitable specification to meet the needs of pump lifting. The main two factors are the head and flow of the pump, and the head of the pump is too small , the sewage cannot be lifted up, and the lift of the pump is too large, which will affect the next sewage treatment process. When the flow rate of the pump is too large, there will be insufficient sewage supply for small sewage treatment, which leads to the need to use backflow during sewage treatment It is a waste of energy to make up for it, and it is difficult to manufacture a pump with a small flow rate, and the cost is high, which is rarely seen in the market at present. [0003] In order to solve these problems, people have developed the use o...
