Description

Technical Field

[0001] This invention belongs to the field of water treatment system technology, and particularly relates to an integrated pump station anti-clogging device and its anti-clogging method. Background Technology

[0002] An integrated pumping station is a pressurization device used to lift sewage, rainwater, drinking water, and wastewater. It is manufactured and assembled in a factory and then transported to the site for installation. The existing patent CN111910741A discloses an integrated intelligent interception pump station for backflow prevention, which relates to the field of interception well technology. It addresses the problem that when the intercepting main pipe of a newly built intelligent interception well is connected to the sewage network, the sewage network is already built and its elevation cannot be changed. Since the elevation of the intercepting main pipe in the interception well is low, an integrated pump station is still needed to lift the sewage in the intercepting pipe into the sewage network. This would double the amount of work required for the interception project at the newly built outlet, and the project cost and land use would also increase accordingly. An overflow pipe is installed on one side of the integrated pump station tank, and the overflow pipe and the overflow pipe are integrated into one structure. An inlet pipe is installed on one side of the integrated pump station tank, and an inlet end connector is installed on one side of the inlet pipe. The inlet end connector is fixedly connected to the inlet pipe through a flange. However, when sewage enters the pump through the inlet pipe, it will carry a large amount of silt into the pump station. Due to the reduced flow rate, the silt will gradually settle at the bottom of the pump station to form sludge. When there is too much sludge, it will block the sewage pipe, affecting the discharge of sludge and also aggravating the wear of the water pump. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical problems by providing an integrated pump station anti-clogging device and method, which can promptly clean up silt in the pump station, prevent silt blockage, and thereby improve the operating efficiency and sewage discharge capacity of the pump station.

[0004] In view of this, the present invention provides an integrated pump station anti-clogging device and its anti-clogging method, characterized in that it includes a pump body, wherein an inlet pipe is provided inside the pump station body, and further includes: A crushing device, wherein one end of the water inlet pipe is provided, and the crushing device is used to crush waste in sewage; A cleaning device is installed at the bottom of the pumping station and is connected to a crushing device. The cleaning device is used to clean the silt inside the crushing device and the pumping station. A sewage discharge device is installed at the bottom of the pumping station and is used to remove silt from the pumping station.

[0005] In this technical solution, the crushing device can crush larger volume garbage mixed in the sewage, so that the sewage can flow smoothly in the pump. The cleaning device, connected to the crushing device, can effectively scrape and agitate the debris remaining inside the crushing device and the sludge deposited at the bottom of the pump station, preventing the sludge from accumulating and hardening for a long time. The sewage discharge device, with the cooperation of the cleaning device, promptly discharges the cleaned sludge from the pump station body, thereby effectively improving the overall operational stability and service life of the pump station.

[0006] Furthermore, the pulverizing device includes: A crushing box is fixedly installed at one end of the feed inlet. A screen is provided on the side of the crushing box near the center of the pump body. The screen is used to discharge wastewater from the crushing box. A rotating shaft is rotatably disposed inside the crushing box along the length of the crushing box. A crushing blade is fixedly disposed on the rotating shaft along the axial direction. Multiple crushing blades are disposed along the circumferential direction. Mesh holes are disposed on the crushing blades. Multiple mesh holes are disposed in sequence. The first motor is fixedly installed outside the crushing chamber, and its output end is connected to one end of the rotating shaft.

[0007] In this technical solution, sewage enters the pulverizing box through the inlet pipe. Under the rotation of the rotating shaft driven by the first motor, multiple pulverizing blades rotate. After fully cutting and pulverizing the garbage in the sewage, the pulverized garbage and sewage flow into the pump station through the screen. The multiple mesh holes on the pulverizing blades help reduce water flow resistance during the pulverizing process, improve the efficiency of sewage passing through the pulverizing box, and at the same time, they can further cut and filter some smaller fibrous impurities, making the pulverizing effect more refined.

[0008] Furthermore, the cleaning device includes: The pump body has a platform fixedly installed at its upper part, and the platform is circular. A rinsing mechanism is installed on the platform and connected to the pulverizing box. The rinsing mechanism is used to rinse the residual waste in the pulverizing box. An inner wall cleaning mechanism is provided on the inner circumference of the pump body, and the inner wall cleaning mechanism is used to clean the sludge on the inner circumference of the pump body. A bottom cleaning mechanism is provided at the bottom of the pump body and is used to clean the sludge at the bottom of the pump body.

[0009] In this technical solution, after the water in the rinsing mechanism rinses the crushing box, it flows into the pump body, which softens the sludge inside the pump body and dilutes the sludge, thus facilitating its discharge.

[0010] Furthermore, the rinsing mechanism includes: A high-pressure flushing pipe is installed through the top of the crushing box along its length. The high-pressure flushing pipe is equipped with high-pressure nozzles, and multiple high-pressure nozzles are installed along the length of the crushing box. A medium-pressure flushing pipe is provided, which runs through the grinding chamber along its length and is located on the side of the grinding chamber near the grid. The medium-pressure flushing pipe is equipped with a medium-pressure nozzle, and multiple medium-pressure nozzles are provided along the length of the grinding chamber. The medium-pressure flushing pipe is arranged parallel to the high-pressure flushing pipe. A water tank is fixedly mounted on a platform. A high-pressure pipe and a medium-pressure pipe are installed on the water tank. The high-pressure pipe and the medium-pressure pipe are respectively connected to a high-pressure flushing pipe and a medium-pressure flushing pipe. A high-pressure pump is installed on the high-pressure pipe, and a medium-pressure pump is installed on the medium-pressure pipe.

[0011] In this technical solution, the water in the water tank is delivered to the high-pressure flushing pipe and the medium-pressure flushing pipe by the high-pressure pump and the medium-pressure flushing pipe, respectively. After the crushing device completes the garbage crushing operation, the high-pressure nozzle sprays high-pressure water to wash the stubborn debris attached to the inner wall of the crushing box and the crushing blades; the medium-pressure nozzle sprays medium-pressure water to wash the surface of the grid and prevent the grid mesh from being blocked by small impurities.

[0012] Furthermore, the inner wall cleaning mechanism includes: The scraper is rotatably disposed inside the pump body along the pump body axis. The end of the scraper near the inner wall of the pump body is inclined and the inclined end of the scraper is in contact with the inner wall of the pump body. A connecting rod is fixedly disposed at the end of the scraper away from the inner wall of the pump body. A rotating rod is rotatably mounted on a platform along the axis of the pump body. A connecting shaft is fixedly mounted on the rotating rod, and one end of the connecting shaft is connected to one end of the connecting rod. The second motor is fixedly mounted on the platform, and its output end is connected to one end of the rotating rod.

[0013] In this technical solution, when the second motor starts, it drives the rotating rod to rotate around the axis of the pump body. The connecting shaft on the rotating rod rotates synchronously, driving the scraper connected to the connecting rod to make a circular motion along the inner wall of the pump body, thereby cleaning the sludge on the inner wall of the pump body, preventing the sludge from gradually thickening and affecting the effective volume of the pump station, and at the same time avoiding corrosion damage to the inner wall of the pump body caused by the sludge.

[0014] Furthermore, the bottom cleaning mechanism includes: A cleaning rod is horizontally positioned at the bottom of the pump body, and one end of the cleaning rod is fixedly connected to one end of the rotating rod. A brush is rotatably mounted on a cleaning rod, and the top end of the brush is fixedly connected to the bottom surface of the pump body.

[0015] In this technical solution, when the rotating rod rotates under the drive of the second motor, it drives the cleaning rod to rotate, which in turn drives the brush to perform circumferential cleaning at the bottom of the pump body. The brush is in close contact with the bottom surface of the pump body. During the rotation, it can thoroughly scrub and disturb the sludge deposited on the bottom surface, breaking up the originally hardened sludge and making it easier for it to be discharged by the subsequent sewage discharge device, effectively preventing the sludge from forming dead corners and accumulating at the bottom.

[0016] Furthermore, the high-pressure flushing pipe includes: The first flushing pipe is fixedly installed between the rotating shafts, and the high-pressure nozzle of the first flushing pipe is rotatable. The second flushing pipe is located on the side wall of the crushing chamber. There are two second flushing pipes, and the high-pressure nozzles on the second flushing pipes are directionally inclined.

[0017] In this technical solution, the high-pressure nozzles on the first and second flushing pipes can flush the rotating shaft and the crushing blades in both directions, making the rotating shaft and the crushing blades cleaner, preventing debris from clogging the mesh of the crushing blades, thereby improving the working efficiency of the crushing blades.

[0018] Furthermore, a first high-pressure ball valve and a second high-pressure ball valve are respectively installed on the first flushing pipe and the second flushing pipe.

[0019] In this technical solution, during the cutting and crushing process, due to excessive plastic and fiber entanglement on the rotating shaft, the sensor detects that the rotational speed of the rotating shaft has slowed down, making it unable to effectively cut and crush the waste. The sensor sends a signal to close the water inlet and control the first and second high-pressure ball valves to start working. The first and second high-pressure ball valves increase the water pressure in the first and second flushing pipes to 300-400 bar, thereby dispersing the entangled material on the rotating shaft, ensuring stable operation of the crushing device and preventing damage to the motor.

[0020] Furthermore, the water tank is equipped with a heating element, which is used to heat the water in the water tank.

[0021] In this technical solution, high-pressure water flow combined with high temperature softens and disperses tangled materials such as fibers and plastics. When the sensor detects a slowdown in the rotational shaft's speed, it sends a signal to the heating element in the water tank, heating the water to over 80 degrees Celsius. This hot water is then piped into the pulverizing chamber through a high-pressure pipe, thereby softening the tangled materials on the rotating shaft and facilitating its cleaning. An integrated anti-clogging device for pumping stations and its anti-clogging method are disclosed. Based on the aforementioned integrated anti-clogging device, the anti-clogging method includes the following steps: S1. Garbage shredding: Sewage flows into the shredding box through the inlet pipe. The shredding blades inside the box shred the garbage in the sewage. Then, the sewage carrying the shredded garbage is discharged through the mesh of the grille. S2. Grinding Chamber Cleaning: The water tank of the rinsing mechanism supplies water to the high-pressure rinsing pipe and the medium-pressure rinsing pipe through a high-pressure pump and a medium-pressure pump, respectively. The high-pressure nozzle sprays high-pressure water to rinse the inner wall of the grinding chamber and the debris on the grinding blades, while the medium-pressure nozzle sprays medium-pressure water to rinse the surface of the grid. The rinsed wastewater mixes with the cleaned sludge. During the grinding process, the rotating shaft may become entangled with debris, causing its rotation to slow down. The sensor detects the rotation speed of the rotating shaft. When the rotation speed of the rotating shaft is lower than the minimum speed specified by the sensor, the sensor sends a signal to close the water inlet and control the first and second high-pressure ball valves to pressurize the water flow in the first and second rinsing pipes to 300-400 bar. At the same time, a signal is sent to the heating element on the water tank to heat the water to above 80 degrees Celsius, so that the high-pressure hot water can soften and disperse the debris on the rotating shaft through the high-pressure nozzle, ensuring stable operation of the rotating shaft. If the rotation speed of the rotating shaft is not lower than the minimum speed specified by the sensor, the process continues to step 2. S3. Pump body cleaning: Start the second motor to drive the rotating rod to rotate, which will cause the scraper of the inner wall cleaning mechanism to move in a circular motion along the inner wall of the pump body to scrape off the sludge attached to the inner wall. At the same time, the cleaning rod of the bottom cleaning mechanism will rotate with the rotating rod, which will drive the brush to scrub the sludge deposited at the bottom of the pump body and break up the hardened sludge. S4. Sludge Discharge: The sludge mixture that has been broken up and diluted at the bottom by the cleaning device is extracted from the outside of the pump station body through the sewage discharge device, completing a complete cleaning and sewage discharge operation.

[0022] The beneficial effects of this invention are: 1. The crushing device can break down larger-volume garbage mixed in sewage, so that sewage can flow smoothly in the pump. The cleaning device, connected to the crushing device, can effectively scrape and agitate the debris remaining inside the crushing device and the sludge deposited at the bottom of the pump station, preventing the sludge from accumulating and hardening over a long period of time. The sewage discharge device, in cooperation with the cleaning device, promptly discharges the cleaned sludge from the pump station body, thereby effectively improving the overall operational stability and service life of the pump station.

[0023] 2. During the cutting and shredding process, due to excessive plastic and fiber entanglement on the rotating shaft, the sensor detects that the shaft's rotation speed has slowed down, making it unable to effectively cut and shred the waste. The sensor sends a signal to close the water inlet and activate the first and second high-pressure ball valves. These valves increase the water pressure in the first and second flushing pipes to 300-400 bar, which in turn signals the heating element in the water tank to heat the water to over 80 degrees Celsius. The hot water is then introduced into the shredding chamber through the high-pressure pipe, thus dispersing the entangled material on the rotating shaft, ensuring stable operation of the shredding device, and preventing damage to the motor.

Sewage discharge device 4 is installed at the bottom of the pumping station and is used to discharge silt from the pumping station.

[0031] The crushing device 3 can crush larger volume garbage mixed in the sewage so that the sewage can flow smoothly in the pump. The cleaning device, connected to the crushing device 3, can effectively scrape and agitate the debris remaining inside the crushing device 3 and the sludge deposited at the bottom of the pump station, preventing the sludge from accumulating and hardening for a long time. The sewage discharge device 4, with the cooperation of the cleaning device, promptly discharges the cleaned sludge from the pump station body, thereby effectively improving the overall operational stability and service life of the pump station.

[0032] The pulverizing device 3 includes: The crushing box 5 is fixedly installed at one end of the feed inlet. A grid 6 is provided on the side of the crushing box 5 near the center of the pump body 1. The grid 6 is used to discharge the sewage in the crushing box 5.

The first motor 10 is fixedly installed outside the crushing box 5, and the output end of the first motor 10 is connected to one end of the rotating shaft 7.

[0033] Wastewater enters the pulverizing chamber 5 through the inlet pipe 2. Under the rotation of the rotating shaft 7 driven by the first motor 10, multiple pulverizing blades 8 rotate. After fully cutting and pulverizing the garbage in the wastewater, the pulverized garbage and wastewater flow into the pump station through the screen 6. The multiple mesh holes 9 on the pulverizing blades 8 help reduce water flow resistance during the pulverizing process and improve the efficiency of wastewater passing through the pulverizing chamber 5. At the same time, it can also further cut and filter some smaller fibrous impurities, making the pulverizing effect more refined.

[0034] The cleaning device includes: Platform 11, the upper part of the pump body 1 is fixedly provided with platform 11, and platform 11 is circular; A rinsing mechanism 12 is installed on the platform 11 and connected to the crushing box 5. The rinsing mechanism 12 is used to rinse the garbage remaining in the crushing box 5. The inner wall cleaning mechanism 13 is disposed on the inner circumferential wall of the pump body 1, and the inner wall cleaning mechanism 13 is used to clean the sludge on the inner circumferential wall of the pump body 1. Bottom cleaning mechanism 14 is disposed at the bottom of pump body 1 and is used to clean the sludge at the bottom of pump body 1.

[0035] After rinsing the pulverizing box 5, the water in the rinsing mechanism 12 flows into the pump body 1, which softens the sludge inside the pump body 1 and dilutes the sludge, thus facilitating its discharge.

[0036] The rinsing mechanism 12 includes: A high-pressure flushing pipe 15 is provided, which runs through the top of the crushing box 5 along the length of the crushing box 5. A high-pressure nozzle 16 is provided on the high-pressure flushing pipe 15, and multiple high-pressure nozzles 16 are provided along the length of the crushing box 5. A medium-pressure flushing pipe 17 is installed inside the crushing box 5 near the grid 6 along the length of the crushing box 5. A medium-pressure nozzle 18 is installed on the medium-pressure flushing pipe 17. Multiple medium-pressure nozzles 18 are installed along the length of the crushing box 5. The medium-pressure flushing pipe 17 is arranged parallel to the high-pressure flushing pipe 15. Water tank 19 is fixedly installed on platform 11.

[0037] Water in water tank 19 is pumped to high-pressure flushing pipe 15 and medium-pressure flushing pipe 17 by high-pressure pump 22 and medium-pressure pump 23 respectively. After the crushing device 3 completes the garbage crushing operation, high-pressure nozzle 16 sprays high-pressure water to wash the stubborn debris attached to the inner wall of crushing box 5 and crushing blade 8; medium-pressure nozzle 18 sprays medium-pressure water to wash the surface of grid 6 to prevent the grid 6 mesh from being blocked by small impurities.

[0038] The inner wall cleaning mechanism 13 includes: Scraper 24 is rotatably disposed inside the pump body 1 along the axis of the pump body 1. The end of the scraper 24 near the inner wall of the pump body 1 is inclined and the inclined end of the scraper 24 is in contact with the inner wall of the pump body 1. A connecting rod 25 is fixedly disposed at the end of the scraper 24 away from the inner wall of the pump body 1. A rotating rod 26 is rotatably mounted on a platform 11 along the axis of the pump body 1. A connecting shaft 27 is fixedly mounted on the rotating rod 26, and one end of the connecting shaft 27 is connected to one end of the connecting rod 25. The second motor 28 is fixedly mounted on the platform 11, and its output end is connected to one end of the rotating rod 26.

[0039] When the second motor 28 starts, it drives the rotating rod 26 to rotate around the axis of the pump body 1. The connecting shaft 27 on the rotating rod 26 rotates synchronously, driving the scraper 24 connected to the connecting rod 25 to make a circular motion along the inner wall of the pump body 1, thereby cleaning the sludge on the inner wall of the pump body 1, preventing the sludge from gradually thickening and affecting the effective volume of the pump station, and at the same time avoiding corrosion damage to the inner wall of the pump body caused by the sludge.

[0041] When the rotating rod 26 rotates under the drive of the second motor 28, it drives the cleaning rod 31 to rotate, which in turn drives the brush 32 to perform circumferential cleaning at the bottom of the pump body 1. The brush 32 is in close contact with the bottom surface of the pump body 1. During the rotation, it can thoroughly scrub and disturb the sludge deposited on the bottom surface, breaking up the originally hardened sludge and making it easier for it to be discharged by the subsequent sewage discharge device 4, effectively preventing the sludge from accumulating in dead corners at the bottom.

[0042] Example 2: like Figure 1-5 As shown, the high-pressure flushing pipe 15 includes: The first flushing pipe 29 is fixedly disposed between the rotating shafts 7, and the high-pressure nozzle 16 of the first flushing pipe 29 is rotatable. The second flushing pipe 30 is installed on the side wall of the crushing box 5. There are two second flushing pipes 30. The high-pressure nozzle 16 on the second flushing pipe 30 is directionally inclined.

[0043] The high-pressure nozzles 16 on the first flushing pipe 29 and the second flushing pipe 30 can flush the rotating shaft 7 and the crushing blade 8 in both directions, making the rotating shaft 7 and the crushing blade 8 cleaner and preventing debris from clogging the mesh 9 of the crushing blade 8, thereby improving the working efficiency of the crushing blade 8.

[0044] A first high-pressure ball valve 33 and a second high-pressure ball valve 34 are respectively provided on the first flushing pipe 29 and the second flushing pipe 30.

[0045] During the cutting and shredding process, due to excessive plastic and fiber entanglement on the rotating shaft 7, it is necessary to close the water inlet, stop the motor, and clean the rotating shaft 7. The water pressure in the first flushing pipe 29 and the second flushing pipe 30 is increased to 300-400 bar through the first high-pressure ball valve 33 and the second high-pressure ball valve 34, which can disperse the entangled material on the rotating shaft 7, ensure that the shredding device 3 can operate stably, and avoid damage to the motor.

[0046] The water tank 19 is equipped with a heating element 35, which is used to heat the water in the water tank 19.

[0047] High-pressure water flow combined with high temperature softens and disperses tangled materials such as fibers and plastics. The heating element 35 on the water tank 19 heats the water to over 80 degrees Celsius, and the hot water is then introduced into the pulverizing chamber 5 through the high-pressure pipe 20 to soften the tangled materials on the rotating shaft 7, facilitating its cleaning. An integrated anti-clogging device for pumping stations and its anti-clogging method are disclosed. Based on the aforementioned integrated anti-clogging device, the anti-clogging method includes the following steps: S1. Garbage shredding: Sewage flows into the shredding box 5 through the inlet pipe 2. The shredding blades 8 inside the box shred the garbage in the sewage. Then, the sewage carrying the shredded garbage is discharged through the mesh 9 of the grille 6. S2. Cleaning of the pulverizing chamber 5: The water tank 19 of the rinsing mechanism 12 supplies water to the high-pressure rinsing pipe 15 and the medium-pressure rinsing pipe 17 respectively through the high-pressure pump 22 and the medium-pressure pump 23. The high-pressure nozzle 16 sprays high-pressure water to rinse the inner wall of the pulverizing chamber 5 and the debris on the pulverizing blades 8, and the medium-pressure nozzle 18 sprays medium-pressure water to rinse the surface of the grid 6. The wastewater after rinsing mixes with the cleaned sludge. During the pulverizing process, the rotating shaft 7 is entangled by the tangled material, causing the rotation of the rotating shaft 7 to slow down. The sensor will detect the rotation speed of the rotating shaft 7. When the rotational speed of the rotating shaft 7 is lower than the minimum speed specified by the sensor, the sensor emits a signal to close the water inlet and control the first high-pressure ball valve 33 and the second high-pressure ball valve 34 to pressurize the water flow in the first flushing pipe 29 and the second flushing pipe 30 to 300-400 bar. At the same time, it sends a signal to the heating element 35 on the water tank 19 to heat the water to above 80 degrees Celsius, so that the high-pressure hot water can soften and disperse the entangled material on the rotating shaft 7 through the high-pressure nozzle 16, ensuring that the rotating shaft 7 can operate stably. S3. Pump body 1 cleaning: Start the second motor 28, drive the rotating rod 26 to rotate, drive the scraper 24 of the inner wall cleaning mechanism 13 to make a circular motion along the inner wall of the pump body 1, scrape off the sludge attached to the inner wall, and at the same time, the cleaning rod 31 of the bottom cleaning mechanism 14 rotates with the rotating rod 26, drive the brush 32 to brush the sludge deposited at the bottom of the pump body 1, and break up the hardened sludge. S4. Sludge Discharge: The sludge mixture that has been broken up and diluted at the bottom by the cleaning device is extracted from the outside of the pump station body through the sewage discharge device 4, completing a complete cleaning and sewage discharge operation.

[0048] The embodiments of this application have been described above with reference to the accompanying drawings.

10. The anti-clogging method of the integrated pump station anti-clogging device according to claim 1, characterized in that, Includes the following steps: S1. Garbage crushing: Sewage flows into the crushing box (5) through the inlet pipe (2). The crushing blades (8) in the box crush the garbage in the sewage. Then the sewage carrying the crushed garbage is discharged through the mesh (9) of the grid (6). S2. Cleaning of the crushing box (5): The water tank (19) of the rinsing mechanism (12) supplies water to the high-pressure rinsing pipe (15) and the medium-pressure rinsing pipe (17) respectively through the high-pressure pump (22) and the medium-pressure pump (23). The high-pressure nozzle (16) sprays high-pressure water to rinse the inner wall of the crushing box (5) and the debris on the crushing blades (8). The medium-pressure nozzle (18) sprays medium-pressure water to rinse the surface of the grid (6). The wastewater after rinsing is mixed with the cleaned sludge. During the crushing process, the rotating shaft (7) is entangled by the entangled material, which causes the rotation of the rotating shaft (7) to slow down. The sensor will detect the rotation speed of the rotating shaft (7). When the rotation speed of the rotating shaft (7) is lower than that of the sensor, the sensor will detect the rotation speed of the rotating shaft (7). When the specified minimum speed is reached, the sensor emits a signal to close the water inlet and control the first high-pressure ball valve (33) and the second high-pressure ball valve (34) to pressurize the water flow in the first flushing pipe (29) and the second flushing pipe (30) to 300-400 bar. At the same time, a signal is sent to the heating element (35) on the water tank (19) to heat the water to above 80 degrees Celsius, so that the high-pressure hot water can soften and disperse the entangled material on the rotating shaft (7) through the high-pressure nozzle (16), ensuring that the rotating shaft (7) can operate stably. If the speed of the rotating shaft (7) is not lower than the specified minimum speed of the sensor, the process of step 2 continues. S3. Pump body (1) cleaning: Start the second motor (28) to drive the rotating rod (26) to rotate, which will drive the scraper (24) of the inner wall cleaning mechanism (13) to make a circular motion along the inner wall of the pump body (1) to scrape off the silt attached to the inner wall. At the same time, the cleaning rod (31) of the bottom cleaning mechanism (14) rotates with the rotating rod (26) to drive the brush (32) to brush the silt deposited at the bottom of the pump body (1) and break up the hardened silt. S4. Sludge discharge: The sludge mixture that has been broken up and diluted at the bottom by the cleaning device (4) is pumped out of the pump station body to complete a complete cleaning and sewage discharge operation.
