Description

Technical Field

[0001] This invention relates to the field of sewage suction and purification technology, specifically to a mobile sewage suction and purification vehicle and its purification method. Background Technology

[0002] Sewage suction and purification is an environmentally friendly treatment technology that mainly refers to the use of sewage suction and purification vehicles to treat sewage from sewage pipes and other sources on-site, achieving solid-liquid separation, purification to meet emission standards, and resource recycling. It integrates "extraction, treatment, separation, purification, and recycling," enabling on-site operation and immediate purification, directly transforming pollutants into usable resources at the source, and can be described as a "mobile micro sewage treatment station."

[0003] In current sewage suction operations, the lowering and retraction of the suction hose mostly rely on manual operation. During the manual lowering and retraction process, the position and depth of the suction hose need to be adjusted repeatedly, and the suction hose must withstand the dragging resistance of the sewage inside the pipe. The operation is laborious, and the sewage adhering to the outer wall of the suction hose can easily stain the workers' clothes, causing secondary pollution and posing hygiene and safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile vacuuming and purification vehicle and its purification method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a mobile sewage suction and purification vehicle and its purification method, comprising a sewage tank, and further comprising: The extraction component includes a slide frame, a rotating rod rotatably connected to the surface of the slide frame, a rubber rod fixedly connected to the surface of the rotating rod, a toothed bracket rotatably connected to the end of the rotating rod away from the slide frame, a limiting cavity provided at the end of the sewage tank, a support plate fixedly connected to the inner wall of the limiting cavity, a protective frame fixedly connected to the inner wall of the limiting cavity, the toothed bracket extending to the top outer end of the protective frame at the end away from the rotating rod, and the inner wall of the toothed bracket slidably connected to the surface of the support plate. A solid-liquid separation component, comprising a sludge pressing plate, a drain rack connected to the top of the sludge pressing plate, a filter rack fixedly connected to the bottom of the sludge pressing plate, and the bottom of the drain rack connected to the filter rack; The processing component includes a movable frame, a round rod fixedly connected to the bottom of the movable frame, a stirring plate fixedly connected to the bottom of the round rod, a sieve hole opened at the bottom of the inner wall of the sewage tank, a groove opened at the bottom of the sewage tank, an inclined frame fixedly connected to the inner wall of the groove, and a discharge valve pipe connected to the bottom of the inclined frame.

[0006] Furthermore, a mounting base is fixedly connected to the lower surface of the sewage tank, a transport vehicle is provided below the sewage tank, the sewage tank is installed at the transport location of the transport vehicle via the mounting base, and a dosing device is provided on the top of the sewage tank.

[0007] Further, the extraction component includes an extraction pump, the bottom of which is fixedly connected to the top of the sewage tank. The inlet of the extraction pump is connected to a bend, the bottom of which is connected to a drop pipe. The bottom of the drop pipe is connected to an automatic valve, and the bottom of the automatic valve is connected to a suction pipe. The outlet of the extraction pump is connected to a discharge pipe. The end of the suction pipe away from the extraction pump penetrates the sewage tank and extends into its interior. The sewage tank has a separation chamber inside, and an isolation plate is fixedly connected to its inner wall. A driving device is fixedly connected to the inner wall of the protective frame. A sliding groove is formed at the end of the limiting chamber away from the protective frame. The end of the sliding plate away from the rotating rod is slidably connected to the inner wall of the sliding groove. An automatic three-way valve is connected to the end of the discharge pipe away from the extraction pump. The surface of the three-way valve is connected to a telescopic pipe. A collection rack is slidably connected to the inner wall of the sewage tank. A bracket is fixedly connected to the bottom of the inner wall of the collection rack. The top of the bracket is fixedly connected to the bottom of the slide frame and the bottom of the toothed frame, respectively. When the rotating rod rotates, it will drive the slide frame to slide inside the slide groove. The slide frame supports the rotating rod and improves the stability of the rotating rod when it moves. When the slide frame moves, it will push the collection rack to move synchronously. When the suction pipe retracts into the limiting cavity, the collection rack will be located below the suction pipe. The collection rack is used to collect the sewage in the suction pipe, preventing the sewage in the suction pipe from dripping everywhere when the suction pipe moves with the transport vehicle. When it is necessary to collect sewage through the suction pipe, the automatic valve is activated to open, so that the suction pipe and the vertical pipe are connected to each other to treat the sewage.

[0008] Furthermore, the automatic valve is located at the top of the inner wall of the limiting cavity, the suction pipe is located inside the limiting cavity, the suction pipe is a flexible hose, the bottom of the vertical pipe penetrates the sewage tank and extends into the interior of the sewage tank, there are two separation chambers, the two separation chambers are symmetrically arranged with the limiting cavity as the center, the surface of the collection rack is in contact with the inner wall of the limiting cavity, and the collection rack is located below the suction pipe.

[0009] Furthermore, there are two rotating rods, which are arranged one above the other and symmetrically about the drive device. The toothed frame meshes with the output end of the drive device, and the surface of the rubber rod is in contact with the surface of the suction pipe.

[0010] Furthermore, the solid-liquid separation component includes a telescopic water suction pipe, the bottom of which is fixedly connected to the top of the sludge pressing plate. The end of the telescopic water suction pipe away from the sludge pressing plate is connected to a transfer valve. The end of the transfer valve away from the telescopic water suction pipe is connected to the surface of the vertical pipe. A linkage frame is fixedly connected to the top of the sludge pressing plate. An electric push rod is fixedly connected to the top of the inner wall of the linkage frame. A water inlet is provided at the bottom of the telescopic water suction pipe. The end of the automatic three-way valve away from the sewage discharge pipe is connected to a water outlet pipe.

[0011] Furthermore, the bottom of the electric push rod penetrates through the sewage tank and extends to the inner wall of the limiting cavity. The surface of the electric push rod is fixedly connected to the top of the inner wall of the limiting cavity. There are two sludge pressing plates, which are symmetrically arranged with the limiting cavity as the center. The surface of the sludge pressing plates is adapted to the inner wall of the separation cavity. The sludge pressing plates are located above the separation cavity. The bottom of the telescopic tube is connected to the top of the sludge pressing plates.

[0012] Furthermore, the processing component includes an electric telescopic frame, the end of which is fixedly connected to the inner wall of the sewage tank. A sealing plate is fixedly connected to the telescopic end of the electric telescopic frame, a pull plate is fixedly connected to the surface of the sealing plate, a push plate is fixedly connected to the end of the pull plate away from the sealing plate, a cylindrical rod is fixedly connected to the end of the push plate away from the pull plate, and an inclined plate is fixedly connected to the end of the cylindrical rod away from the push plate. The end of the movable frame away from the cylindrical rod is fixedly connected to the top of the toothed frame. A water level measuring device is installed on the top of the inner wall of the sewage tank. A sealing door is hinged to the end of the sewage tank away from the limiting cavity. A positioning groove is formed on the surface of the isolation plate.

[0013] Furthermore, there are two sealing plates, which are symmetrically arranged around the limiting cavity. The two sealing plates are fixedly connected by a synchronization plate. The surface of the sealing plate is in contact with the inner wall of the separation cavity, the surface of the pusher plate is in contact with the inner wall of the positioning groove, the end of the cylindrical rod away from the pusher plate extends into the interior of the sewage tank, the bottom of the inclined plate is in contact with the bottom of the inner wall of the sewage tank, and the screen holes and the grooves are interconnected.

[0014] Furthermore, a purification method for a mobile vacuum and purification vehicle includes the following steps: S1: During operation, the drive device pushes the two toothed frames to move closer to each other. The suction pipe is lowered into the sewage pipe along with the movement of the rubber rod, automatically lowering the suction pipe and preventing impurities on the surface of the suction pipe from adhering to the worker's clothes when lowering it, while also improving the ease of use of the suction pipe. After the sewage discharge is completed, the drive device pushes the two toothed frames to move away from each other, and the rubber rod squeezes the suction pipe upward to retract, completing the storage of the suction pipe. S2: Under the operation of the pump, the sewage enters the interior of the telescopic pumping pipe through the inlet. At this time, the automatic three-way valve starts to work, connecting the sewage pipe and the outlet pipe. After entering the interior of the sewage pipe, the sewage enters the interior of the sewage tank through the outlet pipe and is separated from solid impurities. S3: When the mobile frame moves, it pulls the round rod and the stirring plate to move back and forth inside the sewage tank. When the stirring plate moves, it mixes the sewage in the sewage tank, so that the sewage and flocculant are mixed together. S4: The electric telescopic frame moves back and forth and pushes the pusher plate to move back and forth inside the separation chamber. When the pusher plate moves back and forth, it will push the impurities to disperse and gather, avoiding a large amount of impurities from accumulating at the discharge point and causing blockage. The method of dispersing and gathering is used to unload impurities, which can avoid impurity blockage.

[0015] The present invention has the following beneficial effects: This invention automates the lowering of the suction pipe into the sewage pipe as the rubber rod moves, preventing impurities from adhering to workers' clothing during the lowering process. It also improves the ease of use, eliminating the need for disassembly and reassembly during sewage discharge. The lowering length of the suction pipe is adjusted by the movement of two toothed brackets. After sewage discharge, the drive device reverses. During this reversal, the two toothed brackets move away from each other through meshing, causing the rubber rod to compress the suction pipe upwards, thus retracting it and enhancing convenience.

[0016] In this invention, wastewater, under pressure, enters the interior of the drainage frame through the filter frame. The filtered wastewater then flows above the pressure plate. When treatment of the wastewater above the pressure plate is required, an automatic valve closes, and a transfer valve opens. The suction generated by the pump enters the telescopic suction pipe through the transfer valve. Under the operation of the pump, the wastewater enters the telescopic suction pipe through the inlet. At this time, an automatic three-way valve starts operating, connecting the drain pipe and the outlet pipe. After entering the drain pipe, the wastewater enters the wastewater tank through the outlet pipe, separating from solid impurities. This allows for separate treatment of wastewater and impurities, preventing impurities from affecting the treatment effect.

[0017] The movable frame of this invention moves a circular rod and an agitator plate back and forth inside the wastewater tank during movement. The agitator plate mixes the wastewater in the tank during this movement, ensuring the wastewater is combined with the flocculant, thus improving the wastewater treatment effect. This invention features an electric telescopic frame that reciprocates and pushes a pusher plate reciprocating inside the separation chamber. During this reciprocating motion, the pusher plate disperses impurities, preventing large accumulations and blockages at the discharge point. This dispersion method effectively unloads impurities, avoiding blockages. As the pusher plate moves, it pushes a sloping panel via a cylindrical rod, opening the sealing door. The sloping panel then pushes the solidified impurities out of the sealing door. As the sloping panel moves towards the partition plate, it uses its inclined surface to scoop up the impurities. Finally, the flat surface of the sloping panel removes the impurities from the sealing door, improving the ease of impurity handling and preventing accumulation of impurities inside the wastewater tank that would be difficult to clean.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The sewage tank 3 is installed at the transport location of the transport vehicle 1 via the mounting base 2. A dosing device 7 is set on the top of the sewage tank 3.

[0025] The extraction component 4 includes an extraction pump 10, the bottom of which is fixedly connected to the top of the sewage tank 3. The inlet of the extraction pump 10 is connected to a bend 18, the bottom of which is connected to a drop pipe 19. The bottom of the drop pipe 19 is connected to an automatic valve, and the bottom of the automatic valve is connected to a suction pipe 14. The outlet of the extraction pump 10 is connected to a drain pipe 11. The end of the suction pipe 14 away from the extraction pump 10 passes through the sewage tank 3 and extends into its interior. The sewage tank 3 has a separation chamber 15 inside, and an isolation plate 12 is fixedly connected to its inner wall. A drive device 29 is fixedly connected to the inner wall of the protective frame 24. A sliding groove 21 is provided at the end of the limiting cavity 13 away from the protective frame 24. The end of the sliding plate frame 22 away from the rotating rod 23 is slidably connected to the inner wall of the sliding groove 21. An automatic three-way valve 17 is connected to the end of the drain pipe 11 away from the extraction pump 10. The surface of 17 is connected to a telescopic tube 16. The inner wall of the sewage tank 3 is slidably connected to a collection rack 20. The bottom of the inner wall of the collection rack 20 is fixedly connected to a support 26. The top of the support 26 is fixedly connected to the bottom of the slide frame 22 and the bottom of the toothed frame 28 respectively. The suction pipe 14 is lowered into the sewage pipe as the rubber rod 25 moves. The suction pipe 14 is lowered automatically, which avoids the impurities on the surface of the suction pipe 14 from adhering to the worker's clothes when the worker lowers the suction pipe 14. At the same time, it improves the convenience of using the suction pipe 14. There is no need to disassemble and install the suction pipe 14 during sewage discharge. The lowering length of the suction pipe 14 is adjusted by the moving distance of the two toothed frames 28. After the sewage discharge is completed, when the drive device 29 moves away from each other, the rubber rod 25 will squeeze the suction pipe 14 upward to retract and complete its storage, improving convenience.

[0026] The automatic valve is located at the top of the inner wall of the limiting cavity 13. The suction pipe 14 is located inside the limiting cavity 13. The suction pipe 14 is a flexible hose. The bottom of the vertical pipe 19 passes through the sewage tank 3 and extends into the sewage tank 3. There are two separation chambers 15. The two separation chambers 15 are symmetrically arranged with the limiting cavity 13 as the center. The surface of the collection rack 20 is in contact with the inner wall of the limiting cavity 13. The collection rack 20 is located below the suction pipe 14.

[0027] There are two rotating rods 23, which are arranged vertically and symmetrically with the drive device 29 as the center. The toothed frame 28 meshes with the output end of the drive device 29, and the surface of the rubber rod 25 contacts the surface of the suction pipe 14.

[0028] The solid-liquid separation component 5 includes a telescopic suction pipe 31, the bottom of which is fixedly connected to the top of a sludge-pressing plate 32. A transfer valve 30 is connected to the end of the telescopic suction pipe 31 away from the sludge-pressing plate 32. A vertical pipe 19 is connected to the surface of the transfer valve 30 away from the telescopic suction pipe 31. A linkage frame 35 is fixedly connected to the top of the sludge-pressing plate 32, and an electric actuator 37 is fixedly connected to the top of the inner wall of the linkage frame 35. A water inlet 36 is opened at the bottom of the telescopic suction pipe 31. An outlet pipe 34 is connected to the end of an automatic three-way valve 17 away from the drain pipe 11. After being pressurized, the wastewater passes through a filter frame 38 and enters the interior of a drain frame 33. At this point, the filtered wastewater... The wastewater will flow to the top of the sludge press plate 32. When the wastewater above the sludge press plate 32 needs to be treated, the automatic valve is activated and closed, and the transfer valve 30 is opened. The suction generated by the pump 10 during operation will enter the interior of the telescopic suction pipe 31 through the transfer valve 30. Under the operation of the pump 10, the wastewater enters the interior of the telescopic suction pipe 31 through the inlet hole 36. At this time, the automatic three-way valve 17 starts to operate, connecting the sewage pipe 11 and the outlet pipe 34. After the wastewater enters the interior of the sewage pipe 11, it enters the interior of the wastewater tank 3 through the outlet pipe 34 and is separated from solid impurities, so that the wastewater and impurities can be treated separately, avoiding the wastewater containing impurities from affecting the treatment effect.

[0029] The bottom of the electric push rod 37 penetrates the sewage tank 3 and extends to the inner wall of the limiting cavity 13. The surface of the electric push rod 37 is fixedly connected to the top of the inner wall of the limiting cavity 13. There are two sludge pressing plates 32. The two sludge pressing plates 32 are symmetrically arranged with the limiting cavity 13 as the center. The surface of the sludge pressing plates 32 is adapted to the inner wall of the separation cavity 15. The sludge pressing plates 32 are located above the separation cavity 15. The bottom of the telescopic tube 16 is connected to the top of the sludge pressing plates 32.

[0030] The processing component 6 includes an electric telescopic frame 40. The end of the electric telescopic frame 40 is fixedly connected to the inner wall of the sewage tank 3. A sealing plate 42 is fixedly connected to the telescopic end of the electric telescopic frame 40. A pull plate 41 is fixedly connected to the surface of the sealing plate 42. A pusher plate 44 is fixedly connected to the end of the pull plate 41 away from the sealing plate 42. A cylindrical rod 52 is fixedly connected to the end of the pusher plate 44 away from the pull plate 41. An inclined plate 49 is fixedly connected to the end of the cylindrical rod 52 away from the pusher plate 44. A movable frame 46 is located away from the cylindrical rod 52. One end of 1 is fixedly connected to the top of the toothed frame 28. A water level measuring device 45 is installed on the top of the inner wall of the sewage tank 3. A sealing door 48 is hinged to the end of the sewage tank 3 away from the limiting cavity 13. A positioning groove 53 is opened on the surface of the isolation plate 12. When the moving frame 46 moves, it pulls the round rod 51 and the stirring plate 47 to move back and forth inside the sewage tank 3. When the stirring plate 47 moves, it mixes the sewage in the sewage tank 3, so that the sewage and the flocculant are mixed together, thereby improving the sewage treatment effect.

[0031] Two sealing plates 42 are provided, symmetrically arranged around the limiting cavity 13. The two sealing plates 42 are fixedly connected by a synchronization plate 43. The surface of the sealing plate 42 contacts the inner wall of the separation cavity 15, and the surface of the pusher plate 44 contacts the inner wall of the positioning groove 53. The end of the cylindrical rod 52 away from the pusher plate 44 extends into the interior of the sewage tank 3. The bottom of the inclined plate 49 contacts the bottom of the inner wall of the sewage tank 3. The screen hole 50 and the groove 55 are interconnected. The electric telescopic frame 40 reciprocates and pushes the pusher plate 44 to reciprocate inside the separation cavity 15. When the pusher plate 44 reciprocates, it pushes impurities. In the event of aggregation, to prevent a large amount of impurities from accumulating at the discharge point and causing blockage, the aggregation method is used to unload the impurities, which can avoid blockage. When the pusher plate 44 moves, it pushes the inclined plate 49 to move via the cylindrical rod 52, opening the sealing door 48. When the inclined plate 49 moves, it pushes the solidified impurities out of the sealing door 48. When the inclined plate 49 moves towards the isolation plate 12, it uses its inclined surface to scoop up the impurities. Finally, the plane of the inclined plate 49 removes the impurities from the sealing door 48, improving the convenience of impurity handling and preventing impurities from accumulating inside the sewage tank 3 and making it inconvenient to clean.

[0032] A purification method using a mobile vacuum and purification vehicle includes the following steps: S1: During operation, the drive unit 29 pushes the two toothed frames 28 to move closer to each other. The suction pipe 14 is lowered into the sewage pipe along with the movement of the rubber rod 25. The automatic lowering of the suction pipe 14 avoids impurities on the surface of the suction pipe 14 from adhering to the worker's clothes when the worker lowers the suction pipe 14, and at the same time improves the ease of use of the suction pipe 14. After the sewage is discharged, the drive unit 29 pushes the two toothed frames 28 to move away from each other. The rubber rod 25 will squeeze the suction pipe 14 upward to retract, completing the storage of the suction pipe 14. S2: Under the operation of the pumping pump 10, the sewage enters the interior of the telescopic pumping pipe 31 through the inlet 36. At this time, the automatic three-way valve 17 starts to operate, connecting the sewage pipe 11 with the outlet pipe 34. After the sewage enters the interior of the sewage pipe 11, it enters the interior of the sewage tank 3 through the outlet pipe 34 and is separated from solid impurities. S3: When the moving frame 46 moves, it pulls the round rod 51 and the stirring plate 47 to move back and forth inside the sewage tank 3. When the stirring plate 47 moves, it mixes the sewage in the sewage tank 3, so that the sewage and the flocculant are mixed together. S4: The electric telescopic frame 40 moves back and forth and pushes the pusher plate 44 to move back and forth inside the separation chamber 15. When the pusher plate 44 moves back and forth, it will push the impurities to disperse and gather, so as to avoid a large number of impurities accumulating at the discharge point and causing blockage. The impurities are discharged by dispersing and gathering, which can avoid impurity blockage.

[0033] In use, after the transport vehicle 1 transports the sewage tank 3 to the sewage treatment plant, the drive unit 29 is activated to begin operation. During operation, the drive unit 29 pushes two toothed frames 28 to move closer together. As the toothed frames 28 move, they push the rubber rod 25 synchronously via the rotating rod 23. The suction pipe 14 is lowered into the sewage pipe along with the rubber rod 25. This automated lowering of the suction pipe 14 avoids impurities from adhering to workers' clothing during the lowering process, and also improves the ease of use of the suction pipe 14, eliminating the need for disassembly and installation during sewage discharge. The length of the suction pipe 14 is adjusted by the movement distance of the two toothed brackets 28. After the sewage discharge is completed, the drive device 29 reverses. When the drive device 29 reverses, it pushes the two toothed brackets 28 to move away from each other through meshing. The rubber rod 25 will squeeze the suction pipe 14 upward to retract and complete its storage, improving convenience. After the suction pipe 14 is lowered into the sewage pipe, the extraction pump 10 is started to start the operation. Under the operation of the extraction pump 10, the suction pipe 14 will transfer the sewage to the inside of the sewage pipe 11. The automatic three-way valve 17 discharges the sewage into the separation chamber 15 through the telescopic pipe 16 for separation. When the drive device 29 pushes the tooth frame 28 to move back and forth and closer to each other, the rubber rod 25 will pull the suction pipe 14 up and down inside the sewage pipe as it moves. When the suction pipe 14 moves up and down, it will stir and flush the sewage and sediment in the pipe, making the hardened sludge loose and easier to be carried away by the suction pipe. After the wastewater enters the separation chamber 15, when the electric actuator 37 moves downward, it pushes the pressure plate 32 downward through the linkage frame 35. As the pressure plate 32 moves downward, it enters the separation chamber 15 and squeezes the wastewater. Under pressure, the wastewater passes through the filter frame 38 and enters the drainage frame 33. At this point, the filtered wastewater flows above the pressure plate 32. When the wastewater above the pressure plate 32 needs to be treated, the automatic valve closes, the transfer valve 30 opens, and the suction generated by the pump 10 during operation flows through the transfer valve 30. Sewage enters the interior of the telescopic pumping pipe 31 under the operation of the pumping pump 10 through the inlet 36. At this time, the automatic three-way valve 17 starts to operate, connecting the sewage pipe 11 and the outlet pipe 34. After entering the sewage pipe 11, the sewage enters the sewage tank 3 through the outlet pipe 34 and is separated from solid impurities, so that the sewage and impurities can be treated separately, avoiding the sewage containing impurities from affecting the treatment effect. The dosing device 7 is started to add flocculant into the sewage tank 3, and the flocculant is used to treat the fine impurities in the sewage. When the toothed frame 28 lowers and retracts the suction pipe 14, it pulls the moving frame 46 to move inside the sewage tank 3. During this movement, the moving frame 46 pulls the round rod 51 and the stirring plate 47 to reciprocate inside the sewage tank 3. The stirring plate 47 mixes the sewage in the sewage tank 3, allowing the sewage to mix with the flocculant, thus improving the treatment effect. After opening the discharge valve pipe 56, the treated sewage is discharged through it. After the sewage is discharged, the flocculant impurities remain inside the sewage tank 3. The electric telescopic frame 40 is activated to push the sealing plate 42 towards the outer end of the separation chamber 15. During this movement, the sealing plate 42 pulls the pusher plate 44 via the pull plate 41. The pusher plate 44 pushes the impurities in the separation chamber 15 towards the sealing plate 42. When there are too many impurities inside the separation chamber 15, the electric telescopic frame 40 reciprocates and pushes the pusher plate 44 into the separation chamber 15. The internal reciprocating movement of the pusher plate 44 causes impurities to disperse and aggregate during its reciprocating movement, preventing a large amount of impurities from accumulating at the discharge point and causing blockage. This dispersion and aggregation method for unloading impurities avoids blockage. As the pusher plate 44 moves, it pushes the inclined plate 49 via the cylindrical rod 52, opening the sealing door 48. The inclined plate 49 then pushes the solidified impurities out of the sealing door 48. When the inclined plate 49 moves towards the isolation plate 12, it uses its inclined surface to scoop up the impurities. Finally, the plane of the inclined plate 49 removes the impurities from the sealing door 48, improving the ease of impurity handling and preventing impurities from accumulating inside the wastewater tank 3 and becoming difficult to clean. When clean water is added to the wastewater tank 3 and the separation chamber 15, the pusher plate 44 and the inclined plate 49 move, pushing the clean water to rinse their interiors. After rinsing, the impurities are directly discharged from the separation chamber 15 and the wastewater tank 3, improving the ease of cleaning the wastewater tank 3.
