Description

Technical Field

[0001] The utility model relates to the technical field of sewage lifting equipment, in particular to a separated sewage lifting pump station. Background Art

[0002] In the sewage treatment and discharge system, sewage lifting pump stations play a vital role. They are responsible for collecting sewage from low-lying areas or far away from the treatment plant and lifting it to an appropriate height for subsequent treatment or discharge. However, when using traditional sewage lifting pump stations, there are still the following problems:

[0003] The traditional sewage lifting pump station is not effective in separating solids and liquids from sewage, especially for sewage containing a large amount of solid waste, such as rainwater and domestic sewage in urban drainage systems. If effective solid-liquid separation is not performed, it will not only increase the burden on subsequent treatment equipment, but may also cause pipe blockage and affect the normal operation of the entire system.

[0004] Currently, most sewage lifting pump stations on the market use simple filters or grilles for solid-liquid separation. Although this method can reduce the amount of solid waste entering the subsequent treatment system to a certain extent, the separation effect is limited, and the separated waste needs to be cleaned frequently, which is not convenient to use.

[0005] In view of the above problems, the utility model document proposes a separate sewage lifting pump station. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the existing sewage lifting pump station in the prior art, such as the poor solid-liquid separation effect of the existing sewage lifting pump station and the inconvenience in cleaning the waste residue, and to propose a separation type sewage lifting pump station.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A water collecting tank, the water collecting tank is used to collect sewage, a separation box and a fixing plate are fixedly installed on one side of the water collecting tank, the separation box is located above the fixing plate, and the bottom of the fixing plate is flush with the bottom of the water collecting tank;

[0010] It also includes a sewage pump, which is fixedly installed on the top of the fixed plate, one end of the water inlet of the sewage pump is connected to the inside of the water collecting tank through a pipeline, and one end of the water outlet of the sewage pump is fixedly installed with a water outlet pipe, and the water outlet pipe is used to discharge sewage;

[0011] It also includes a solid-liquid separation component, which is used to filter and separate solid waste residues in sewage.

[0012] In a possible design, the solid-liquid separation component includes a guide plate fixedly mounted on the inner wall of the separation box, the guide plate being tilted to ensure that the sewage falling thereon can be smoothly retained, a water inlet is provided on one side of the water collecting box, the water collecting box is connected with the separation box through the water inlet, one end of the guide plate extends into the water inlet to ensure that the sewage can smoothly fall into the water collecting box, two support plates are fixedly mounted on the inner wall of the separation box, the two support plates are both located above the guide plates, through holes are provided inside the two support plates, a separator is rotatably arranged between the two support plates, an inlet pipe is fixedly mounted on the top of the support plate located above, one end of the inlet pipe cooperates with an adjacent through hole for transporting sewage into the separator, a slag discharge pipe is fixedly mounted on the bottom of the support plate located below, one end of the slag discharge pipe cooperates with an adjacent through hole, and the other end of the through hole is fixedly passed through one side of the separation box, and the slag discharge pipe is used to discharge solid waste separated in the separator.

[0013] In a possible design, the separator is composed of a mounting base plate, a mounting top plate, and a separation filter tube. The separation filter tube is located between the mounting base plate and the mounting top plate and is fixedly connected to the mounting base plate and the mounting top plate. A plurality of filter holes are provided on the outer wall of the separation filter tube. The mounting base plate and the mounting top plate are rotatably connected to adjacent support plates through protrusions, respectively. A sewage discharge hole is provided at a position of the mounting base plate deviating from the center of a circle, and the sewage discharge hole cooperates with an adjacent through hole. An arc groove is provided inside the mounting top plate, and the arc groove cooperates with the adjacent through hole.

[0014] In a possible design, a reduction motor is fixedly mounted on the bottom inner wall of the separation box, and a rotating shaft is fixedly mounted on one end of the output shaft of the reduction motor. One end of the rotating shaft rotates through the guide plate and is fixedly connected to the bottom end of the protrusion of the mounting base. The reduction motor is used to drive the separator to rotate, thereby periodically aligning the sewage discharge hole, the arc groove and the adjacent through hole.

[0015] In a possible design, a pressure reducing pipe is provided in the water inlet pipe, and the pressure reducing pipe is used to simply store the sewage in the water inlet pipe to avoid an increase in the pipe pressure in the water inlet pipe when the separator is closed.

At this time, the transportation of sewage can be temporarily stopped, and the sewage will be temporarily stored in the pressure reducing pipe; when the sewage discharge hole is aligned with the adjacent through hole, the solid waste residue in the separator will enter the residue discharge pipe through the sewage discharge hole, and finally be discharged from the inside of the separator. As the sewage treatment proceeds, the discharge of solid waste residue will gradually and automatically be exhausted; when the sewage water level in the water collecting tank gradually rises and reaches the preset position, the liquid level switch will send a signal to control the sewage pump to start, and the sewage pump can pump out the sewage in the water collecting tank to complete the sewage transportation; when the sewage water level drops to a certain position, the liquid level switch will send a signal again to control the sewage pump to shut down, so as to realize the intermittent operation of the sewage pump and save energy.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Reference Figure 1-5 A sewage lifting pump station includes: a water collecting tank 1, a separation tank 2, a fixed plate 7, a sewage pump 8, a water outlet pipe 4 and a solid-liquid separation component.

[0032] First, the water collecting tank 1 is the main part of the entire pumping station and is used to collect sewage to be treated. A separation box 2 and a fixed plate 7 are fixedly installed on one side of the water collecting tank 1. The separation box 2 is located above the fixed plate 7, and the bottom of the fixed plate 7 is flush with the bottom of the water collecting tank 1. This design not only ensures the stability of the structure, but also facilitates the installation of subsequent components.

[0033] A sewage pump 8 is fixedly installed on the top of the fixed plate 7. The water inlet 9 of the sewage pump 8 is connected with the interior of the water collecting tank 1 through a pipe so as to suck the sewage in the water collecting tank 1; at the same time, an outlet pipe 4 is fixedly installed at one end of the water outlet of the sewage pump 8. The outlet pipe 4 is responsible for discharging the treated sewage from the pump station, entering the subsequent treatment process or discharging it to a designated location.

[0034] In order to achieve solid-liquid separation of sewage, the present embodiment further provides a solid-liquid separation component; the component includes a guide plate 10 fixedly mounted on the inner wall of the separation box 2, and the guide plate 10 is tilted to ensure that the sewage can flow down smoothly and fall into the water collecting tank 1 after preliminary guidance; a water inlet 9 is provided on one side of the water collecting tank 1, and the water inlet 9 is connected to the separation box 2, and one end of the guide plate 10 extends into the water inlet 9 to ensure that the sewage can flow smoothly into the water collecting tank 1.

[0035] Two support plates 14 are fixedly installed on the inner wall of the separation box 2. The two support plates 14 are both located above the guide plate 10. Through holes 15 are provided inside the two support plates 14 for the circulation of sewage and the discharge of solid waste residues; a separator 11 is rotatably arranged between the two support plates 14, and a water inlet pipe 3 is fixedly installed on the top of the upper support plate 14, one end of which is connected to the adjacent through hole 15 for conveying sewage to the separator 11 for treatment; a slag discharge pipe 5 is fixedly installed on the bottom of the lower support plate 14, one end of which is also connected to the adjacent through hole 15 for discharging the solid waste residue separated in the separator 11.

[0036] The specific structure of the separator 11 includes a mounting base plate 16, a mounting top plate 17 and a separation filter tube 18 located therebetween. A plurality of filter holes are provided on the outer wall of the separation filter tube 18 for filtering solid waste residues in sewage. The mounting base plate 16 and the mounting top plate 17 are rotatably connected to the adjacent support plates 14 through the protrusions thereon respectively, so as to realize the rotation function of the separator 11. A drain hole 19 is provided at a position deviating from the center of the circle on the mounting base plate 16. The drain hole 19 cooperates with the adjacent through hole 15 and is used to discharge solid waste residues when the separator 11 rotates to a specific position. An arc groove 20 is provided inside the mounting top plate 17. The arc groove 20 also cooperates with the adjacent through hole 15 to facilitate the injection of sewage.

One end of the rotating shaft 13 rotates through the guide plate 10 and is fixedly connected to the bottom end of the protrusion of the mounting base 16; when the reduction motor 12 is started, it will drive the separator 11 to rotate, so that the sewage discharge hole 19, the arc groove 20 and the adjacent through hole 15 are periodically aligned, thereby realizing the regular discharge of solid waste.

[0038] The present application can be used in the technical field of sewage lifting equipment, and can also be used in other fields applicable to the present application.

[0039] Example 2

[0040] refer to Figure 3 , 4 , improved on the basis of Example 1: a separated sewage lifting pump station, which is applied to the technical field of sewage lifting equipment;

[0041] In addition, in order to improve the stability and safety of the system, a pressure reducing pipe 6 is provided in the water inlet pipe 3 for simply storing the sewage in the water inlet pipe 3 to avoid a sharp increase in the pipe pressure in the water inlet pipe 3 when the separator 11 is closed.

[0042] Finally, a liquid level switch 21 is fixedly installed on the inner wall of one side of the water collecting tank 1. The liquid level switch 21 is located below the guide plate 10 and is electrically connected to the sewage pump 8 for real-time monitoring of the water level inside the water collecting tank 1. When the water level reaches a preset value, the liquid level switch 21 will send a signal to control the sewage pump 8 to start and discharge the sewage in the water collecting tank 1. When the water level drops to a certain range, the sewage pump 8 will stop to ensure the normal operation of the pump station. The liquid level switch 21 is specifically a float liquid level switch, which is the same as that in the patent with announcement number CN221235370U.

[0043] The sewage pump 8 and the pressure reducing pipe 6 are both provided with protective shells on the outside, which are fixedly connected to the water collecting box 1 and the separation box 2 to protect the equipment and improve the sealing performance and aesthetics of the device.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the sewage pump 8 and the reduction motor 12 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0045] The working principle and use process of this technical solution are as follows: when in use, turn on the power supply and start the reduction motor 12. The reduction motor 12 can drive the separator 11 to rotate slowly through the rotating shaft 13, and then the sewage will be transported to the separator 11 through the water inlet pipe 3; when the separator 11 is rotating, when the arc groove 20 is aligned with the adjacent through hole 15, the sewage can enter the separator 11 normally, and the liquid part in the sewage will pass through the separation filter tube 18 and fall on the guide plate 10, and finally pass through the water inlet 9 along the guide plate 10 and be stored in the water collecting tank 1, while the solid waste residue in the sewage will be left in the separator 11, completing the solid-liquid separation of the sewage; when the separator 11 rotates, the sewage discharge hole 19 at the bottom of the separator 11 will periodically align with the adjacent through hole 15, and at this time the arc groove 20 at the top will align with the adjacent through hole 15. The shaped groove 20 will be staggered with the adjacent through hole 15, at which time the transportation of sewage can be temporarily stopped, and the sewage will be temporarily stored in the pressure reducing pipe 6; when the sewage discharge hole 19 is aligned with the adjacent through hole 15, the solid waste residue in the separator 11 will enter the residue discharge pipe 5 through the sewage discharge hole 19, and finally complete the discharge from the inside of the separator 11. As the sewage treatment proceeds, the discharge of the solid waste residue will gradually and automatically be exhausted; when the sewage water level in the water collecting tank 1 gradually rises and reaches the preset position, the liquid level switch 21 will send a signal to control the sewage pump 8 to start, and the sewage pump 8 can pump out the sewage in the water collecting tank 1 to complete the transportation of sewage; when the sewage water level drops to a certain position, the liquid level switch 21 will send a signal again to control the sewage pump 8 to shut down, so as to realize the intermittent operation of the sewage pump 8 and save energy.
