[0009] The pump body is connected to the box body through the main water pumping pipeline, and a ball valve is provided at the connection between the main water pumping pipeline and the first water pumping pipeline and the second water pumping pipeline.

[0010] Furthermore, the inclination angle of the first filter is smaller than the inclination angle of the second filter.

[0040] This embodiment provides an integrated sewage lifting pump, comprising:

[0041] A box 1, one side of which is provided with a sewage inlet pipe 2, and a first filter screen 3, a second filter screen 4 and an oblique flow plate 5 are arranged inside, wherein the first filter screen is arranged in the upper middle part of the box, the second filter screen is arranged in the lower middle part of the box, and the oblique flow plate is arranged at the bottom of the box;

[0042] A pumping pipeline, part of which is arranged in the box, includes a first pumping pipeline 6, a second pumping pipeline 7 and a main pumping pipeline 8, wherein the first pumping pipeline and the second pumping pipeline are arranged in an unenclosed space formed by a water-blocking baffle 12 and a side away from the sewage inlet pipeline box;

[0043] The pump body 9 is connected to the box body through the main water pumping pipeline. A ball valve 10 is provided at the connection between the main water pumping pipeline and the first water pumping pipeline and the second water pumping pipeline.

[0044] The ball valve is a three-way ball valve, which includes a handle, a valve stem and a valve seat. The handle 1001 is connected to the valve seat 1003 through the valve stem 1002 .

[0045] Specifically, the inclination angle of the first filter is smaller than the inclination angle of the second filter.

[0046] Preferably, the inclination angle of the first filter screen should be no less than 5°.

[0047] The first filter screen has a smaller inclination angle than the second filter screen, which helps the sewage to gradually deposit solid particles during the filtering process and reduce the clogging of the filter screen.

[0048] Specifically, the first filter screen and the second filter screen are fixed in the box body by a blocking bar 11;

[0049] The two groups of blocking bars below the first filter screen and the two groups of blocking bars below the second filter screen are respectively arranged opposite to each other in the horizontal direction.

[0050] The barrier bars are used to fix the filter net. Setting them opposite to each other in the horizontal direction helps to evenly distribute the flow of sewage and enhance the filtering effect.

[0051] Specifically, there is no corresponding relationship between the two groups of blocking bars below the first filter screen and the two groups of blocking bars below the second filter screen in the vertical direction.

[0052] There is no corresponding relationship between the blocking bars in the vertical direction, which means that their functions are independent and will not interfere with each other, and it is more convenient to replace the filter.

[0053] Specifically, the height from the water suction port of the first water suction pipeline to the bottom of the box is higher than the height from the water suction port of the second water suction pipeline to the bottom of the box.

[0054] The height from the first pumping pipe to the bottom of the tank is higher than the height from the second pumping pipe to the bottom of the tank, which helps to perform more effective suction according to the distribution of solid particles in the sewage.

[0055] Specifically, the inner diameter of the first water pumping pipeline is smaller than the inner diameter of the second water pumping pipeline.

[0056] The inner diameter of the first pumping pipeline is smaller than that of the second pumping pipeline, and is used to control the flow or adapt to sewage of different filtration levels.

[0057] Specifically, the cross-sectional shape of the barrier strip is a quadrilateral;

[0058] Among them, the inclination angle of one side matches the inclination angle of the corresponding filter screen.

[0059] The quadrilateral cross section with one side tilted at an angle matching the filter helps to improve the stability and filtering efficiency of the filter.

[0060] Specifically, the sewage outlet 13 is arranged on a side close to the second pumping pipeline.

[0061] The water outlet is arranged on a side close to the second water pumping pipeline, which helps to improve the cleaning efficiency when cleaning the box.

[0062] Specifically, one end of the high side of the inclined flow plate is connected to a box body close to the first pumping pipeline.

[0063] One end of the high side of the inclined flow plate is connected to a box body close to the first pumping pipeline, which helps to further optimize the water flow, reduce vortex and short-circuit flow, and improve the performance of the pump.

[0064] Specifically, the distance from the water-blocking baffle to the bottom of the box body is smaller than the distance from the second pumping pipeline to the bottom of the box body.

[0065] The distance between the water-blocking baffle and the bottom of the box is smaller than the distance from the second pumping pipeline to the bottom of the box, which helps to maintain a certain water level difference and improve the pumping efficiency.

[0066] Specifically, the working principle of the integrated sewage lifting pump is as follows: when in use, open the sewage inlet pipe, and the sewage passes through the first filter, the second filter and the oblique flow plate in turn. When passing through the first filter, since the first filter is provided with an inclined angle, the sewage can pass through slowly at a certain flow rate. Due to the first filter, the sewage is filtered for the first time. At this time, larger particles of sand and gravel are filtered out. When passing through the second filter, smaller particles of sand and gravel are filtered out to enhance the filtering effect. After flowing through the oblique flow plate, the sewage sediment is on the side of the box body close to the second pumping pipe. When the sewage reaches the pumping port of the first pumping pipe, adjust the ball valve, start the pump body, and extract sewage. After the sewage sediment accumulates to a certain thickness, adjust the ball valve, and use the second pumping pipe to extract sewage. When cleaning the box body, opening the sewage outlet can speed up the cleaning speed and improve the cleaning efficiency.

Without departing from the principle of the utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the utility model.

[0068] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model; for those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
