At present, the housing construction in China is mainly divided into five categories: enterprise unit housing, hospitals, hotels, high-rise buildings and residential housing. Generally, the contemporary houses constructed are all equipped with underground sewage treatment rooms. Since the area of sewage to be treated is very large, sewage treatment plants have been built to achieve sewage treatment in a centralized manner. The centralized treatment of sewage requires the large-area sewage discharged to be centrally transported to the sewage treatment plant. During the sewage transportation process, due to the long distance, the sewage needs to be lifted by a sewage lift station and then sent to the sewage treatment plant through a sewage pipeline.

[0003] The sewage lift pump stations used in the existing technology in China usually adopt the way of sump for sewage discharge. The sewage lift pump station mainly includes: a sump, a sewage pump, a liquid level controller and an electric control box. The sewage pump and the liquid level controller are arranged inside the sump, and both are connected to the electric control box through their respective cables. Among them, the sewage pump is fixed in the sump through a coupling device. When the water level in the sump starts to rise and reaches the height set by the liquid level controller, the liquid level controller activates the electric control box, and the electric control box starts to start the sewage pump. The sewage pump lifts and transports the sewage to the outdoor drainage well or the municipal pipe network.

[0033] As Figures 1-4 shown, this embodiment provides a sewage lift pump station.

[0034] A sewage lift pump station includes,

[0035] A water collecting tank 100, including at least two sewage inlets 101 and one sewage outlet, and the sewage inlet 101 is located in the area near the bottom of the box body 110, and the sewage outlet is located at the top of the water collecting tank 100;

[0036] Sewage pumps 300, at least two are provided, and each sewage pump 300 is provided with a sewage pipe 400 communicated with the sewage outlet;

[0037] A sewage connection 500 is provided at the sewage outlet, and the water inlet of the sewage connection 500 is connected at the sewage outlet;

[0038] Each sewage pump 300 is controlled to start and stop separately.

[0039] The above is the basic scheme of this embodiment.

[0040] Specifically refer to Figure 1 and Figure 2As shown, the sewage inlet 101 is arranged on the two side walls of the box body 110 and close to the bottom of the box body 110, and the sewage outlet is arranged on the top; the sewage enters the water collecting box 100 from the sewage inlet 101 on both sides, and under the action of the sewage pump 300, the sewage is lifted from the sewage pipe 400 to the sewage outlet, and output to the outside from the sewage connector 500;

[0041] The present embodiment is provided with a controller 200 to control the sewage pump 300. By setting a program in the controller 200, the sewage pump 300 can be started and stopped for use individually, or started and stopped for use simultaneously, and can also be set to be used alternately.

[0042] A plurality of sewage pumps 300 are provided. When two sewage pumps 300 are used at the same time, the load of a single sewage pump 300 is reduced, and the sewage lifting efficiency is improved, thereby extending the service life of the sewage pump 300.

[0043] When the amount of sewage is small, only one sewage pump 300 is started or two sewage pumps 300 are set to start at the same time, thereby reducing the working time of a single sewage pump 300 and extending the service life of the sewage pump 300.

[0044] In this embodiment, the sewage discharge joint 500 is configured as a constricted structure along the sewage discharge direction.

[0045] The two sewage pipes 400 are both connected to the input port of the sewage joint 500 , and are output from the output port after being merged in the sewage joint 500 .

[0046] The sewage connector 500 is configured to have a constricted structure, with the large end being used to connect the two sewage pipes 400 and the small end being used to connect external pipe fittings, thereby meeting the assembly requirements of the pipe fittings.

[0047] Specifically, to facilitate connection with external pipelines, in this embodiment, the sewage joint 500 includes a water collecting section 510 and a connecting section 520; the water collecting section 510 is a necked structure, and the connecting section 520 is connected to the necked side of the water collecting section 510 for connection with external pipe fittings.

[0048] Specific reference Figure 3 As shown, a groove 122 is provided at the top of the water collecting box 100, and a flange 511 is provided outwardly at the lower end of the water collecting section 510 of the sewage discharge joint 500, and the flange 511 is fixed in the groove 122;

[0049] The top of the water collecting tank 100 is provided with a mounting groove, and the mounting groove is connected to the bottom of the embedded groove 122; the upper end of the sewage pipe 400 extends into the mounting groove;

[0050] The upper end of the sewage pipe 400 is provided with a pipe cover.

[0051] In this embodiment, a water level monitoring component is further included. The water level monitoring component at least includes a low water level pipe 610 and a high water level pipe 620;

[0052] The lower end position of the low water level pipe 610 is lower than the lower end position of the high water level pipe 620.

[0053] Specifically referring to Figure 2 and Figure 4 As shown, the upper ports of the high water level pipe 620 and the low water level pipe 610 are flush. When sewage enters the water collection tank 100 through the sewage inlet 101, as the water level rises, it first contacts the lower end of the low water level pipe 610 and then contacts the lower end of the high water level pipe 620.

[0054] Among them, pneumatic switches 700 are arranged at the upper ends of both the low water level pipe 610 and the high water level pipe 620, and the sewage squeezes the gas in the pipes to activate the pneumatic switches 700.

[0055] In this embodiment, the control mode of the pneumatic switch 700 for the sewage pump 300 is that the start and stop of the sewage pump 300 are controlled by the state that both of the two pneumatic switches 700 are activated or not activated.

[0056] When the water level in the water collection tank 100 continues to rise after reaching the lower end of the low water level pipe 610, the gas in the low water level pipe 610 is compressed, thereby activating the pneumatic switch 700 on the low water level pipe 610, and the controller 200 receives the first activation signal;

[0057] As the water level rises, it reaches the lower end of the high water level pipe 620, and continues to rise to squeeze the gas in the high water level pipe 620, so as to activate the pneumatic switch 700 at the upper end of the high water level pipe 620, and the controller 200 receives the second activation signal;

[0058] When the controller 200 receives the activation signals of the two pneumatic switches 700, the program in the controller 200 is activated, and the sewage pump 300 starts to pump the sewage out of the water collection tank 100;

[0059] As the sewage is discharged, the water level in the water collection tank 100 drops. When the water level in the water collection tank 100 drops below the lower port of the high water level pipe 620, the pneumatic switch 700 at the upper end of the high water level pipe 620 closes, and the controller 200 receives the first closing signal;

[0060] When the water level continues to drop and drops below the lower port of the low water level pipe 610, the pneumatic switch 700 at the upper end of the low water level pipe 610 closes, and the controller 200 receives the second closing signal;

[0061] When the controller 200 receives the two closing signals, it controls the sewage pump 300 to close, and so on in a cycle.

[0062] In this embodiment, the water level monitoring device is disposed between two sewage pumps 300 , and the sewage outlet is located at the top of the area between the two sewage pumps 300 .

[0063] The shape of the sewage pump 300 is approximately cylindrical, and there will be a large space between the two sewage pumps 300. Therefore, in this embodiment, the space is reasonably utilized, two sewage pipes 400 and a water level detection device are set at this position, and the structures on both sides of the water collecting tank 100 are made symmetrical, the length of the sewage pipe 400 is shortened as much as possible, and the occupancy of the internal space is reduced.

[0065] Specific reference Figure 1 As shown, the top of the sewage pump 300 is embedded in the pump port 121 to form a whole with the tank cover 120. At the same time, the handle 310 on the sewage pump 300 extends above the tank cover 120. When the sewage pump 300 needs to be replaced and repaired, it can be directly lifted out from the pump port 121 without disassembling the water collecting tank 100.
