Problems solved by technology

Among them, a commonly used integrated sewage treatment equipment is a sewage lifting pump station, which is often used in the process of sewage treatment. The sewage enters the lifting pump station. After the sewage reaches a certain height, the motor is started to automatically discharge the sewage through the control program. However, after the lifting pump station is used for a long time, there will be more sediment at the bottom of the cylinder, and the fluidity of the sediment is poor. In addition, the long-term accumulation and solidification make it difficult to remove the sediment The accumulation of sediment will reduce the sewage capacity of the cylinder, increase the frequency of motor work, and reduce the working efficiency of the motor. Therefore, special solutions are required.

Embodiment Construction

[0010] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0011] refer to figure 1 As shown, the program-controlled sewage lifting pump station of the present invention includes a cylinder body 1, the side wall of the cylinder body 1 is provided with a water inlet 2 and a water outlet 8, the bottom of the cylinder body 1 is provided with a lifting pump 3, and the top of the cylinder body 1 is provided with There is an exhaust pipe 4 and a control box 5. The control box is equipped with PLC control circuit boards and switches and other components. The lift pump 3 is connected to the water outlet 8 through the drain pipe 6. Of course, since the lift pump is relatively mature equipment, its specific The structure has multiple, also can have multiple changes, and the structure of the present invention is all applicable.

[0012] The present invention also includes a sewage flushing pipe 7, which ...

Abstract

The invention provides a programmed type sewage lifting pump station. The programmed type sewage lifting pump station comprises a barrel, wherein a water inlet and a water outlet are formed in the side wall of the barrel, a lifting pump is arranged on the bottom of the barrel, an air exhaust pipe and a control box are arranged on the top of the barrel, and the lifting pump is connected with the water outlet through a water draining pipe; the programmed type sewage lifting pump station further comprises a pollutant flushing pipe, wherein the pollutant flushing pipe is positioned on the bottom of the barrel, the pollutant flushing pipe communicates with the water draining pipe, and an electromagnetic valve is arranged on the pollutant flushing pipe. The special pollutant flushing pipe is arranged on the bottom of the barrel, through program settings, after the programmed type sewage lifting pump station is used for a period of time, a motor is automatically started and the electromagnetic valve on the pollutant flushing pipe is started, the sewage in the barrel continuously flushes for driving the deposited dirt to be flushed up again, the flushing increases the fluidity of the sediment, so that the accumulation and curing of the sediment can be avoided, after flushing is carried out for a period of time, through the water draining pipeline, the sewage in the barrel is completely drained, and thus the accumulation problem of the sediment is effectively solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a program-controlled sewage lifting pump station. Background technique [0002] All kinds of industrial sewage or domestic sewage are produced in industrial production and social life. With the improvement of people's awareness of environmental protection, the requirements for environmental protection are gradually increasing. Disorderly like that. Among them, a commonly used integrated sewage treatment equipment is a sewage lifting pump station, which is often used in the process of sewage treatment. The sewage enters the lifting pump station. After the sewage reaches a certain height, the motor is started to automatically discharge the sewage through the control program. However, after the lifting pump station is used for a long time, there will be more sediment at the bottom of the cylinder, and the fluidity of the sediment is poor. In addition, the long-term accumul...
