Description

Technical Field

[0001] This invention relates to the field of landfill technology, and more specifically to a backwashing and unblocking structure for preventing siltation in landfill drainage layers. Background Technology

[0002] With the acceleration of urbanization, the amount of municipal solid waste and various types of solid waste generated is increasing daily. Landfill, as a common and widely used method of solid waste disposal, undertakes an important task of waste treatment globally. As a key component of landfills, the landfill drainage layer plays an indispensable role in the timely and effective discharge of leachate, and is an important barrier to ensure the safe and stable operation of landfills.

[0003] The drainage layer plays a crucial role in landfills, its primary task being the timely and effective removal of leachate generated during the landfilling process. After landfilling, factors such as microbial decomposition and rainwater erosion produce large amounts of leachate containing high concentrations of organic matter, heavy metals, and pathogens. If the leachate is not removed promptly, it accumulates within the landfill, raising the water level. This increases the weight of the waste and may trigger geological disasters such as landfill subsidence and landslides.

[0004] When existing landfill drainage layers are in use, the leachate collection holes are easily blocked by particulate sediments and microorganisms carried by the leachate, making it difficult for leachate to be discharged. This can lead to a rise in leachate levels, which can easily pollute the soil and groundwater. Manual cleaning is inefficient and cannot reach deep into the pipes. Furthermore, high-pressure flushing alone is not suitable for the environment inside the pipes, resulting in limited cleaning effectiveness and repeated blockages, which affect the discharge of leachate and the stable operation of the drainage layer. Summary of the Invention

[0005] The purpose of this invention is to provide a backwashing and unblocking structure for preventing siltation in landfill drainage layers, and to solve the following technical problems: When existing landfill drainage layers are in use, the leachate collection holes are easily blocked by particulate sediments and microorganisms carried by the leachate, making it difficult for leachate to be discharged.

[0015] As a further embodiment of the present invention: a plurality of sprockets are fixed on one side of the movable plate, the sprockets are fixedly connected to the reciprocating lead screw, a chain is engaged on the sprocket, a protective shell is fixed on one side of the movable plate, and the sprockets and the chain are both located inside the protective shell.

[0016] The beneficial effects of this invention are: (1) The motor is turned so that the reciprocating screw rotates, which causes the ball nut to drive the moving frame to move back and forth, which causes the cleaning column to drive the cleaning brush to move. The cleaning brush moves back and forth to clean the collection pipe, reducing the residue of particulate impurities and facilitating the discharge of permeate. At the same time, the high-pressure water pump is turned so that the rotating jet nozzle rotates and sprays. The moving frame drives the rotating jet nozzle to move back and forth to spray and clean the pipe and the guide layer, reducing the blockage of the pipe and collection hole by particulate impurities, reducing the accumulation of permeate, and reducing the pollution to the soil and groundwater. With the reciprocating cleaning brush, the cleaning effect on the pipe is further improved, the cleaning dead corners are reduced, the repeated blockage of the pipe is reduced, and the discharge of permeate is facilitated. (2) When the cleaning column moves, it drives the rotating gear to rotate on the moving rack, which in turn drives the cleaning brush to move and rotate, improving the cleaning effect on the pipeline. At the same time, the high-pressure airflow enters the sliding pipe through the connecting pipe and is sprayed out through the rotating jet nozzle to clean the collection hole on the collection pipe, reducing the residue of particulate impurities. The airflow backwashes the guide layer. The arc-shaped scraper moves through the cleaning telescopic rod to scrape and clean large particulate impurities in the pipeline. The cleaning brush further improves the cleaning effect, making it easier to unclog the pipeline and the guide layer. The spring in the cleaning telescopic rod causes the arc-shaped scraper to be forced against the collection pipe. The rotating jet nozzle moves and cleans the pipeline after scraping, flushing the residual particulate matter in the pipeline, reducing cleaning dead angles, reducing the residue of particulate matter, reducing repeated clogging of the pipeline, making it easier to clean manually, and making it easier to operate the pipeline and the guide layer stably.

[0017] (3) When the reciprocating screw rotates, the first bevel gear rotates, which drives the second bevel gear to rotate, causing the adjusting screw to rotate. The adjusting screw moves on the fixed frame, driving the moving plate and the motor to move up and down reciprocally, so that the cleaning brush and the rotating jet nozzle move up and down reciprocally, further improving the cleaning effect on the pipeline, reducing cleaning dead angles, reducing the residue of particles, reducing repeated clogging of the pipeline, facilitating manual cleaning, and facilitating the stable operation of the pipeline and the guide layer.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figure 1 - Figure 3As shown, the present invention is a backwashing and unblocking structure for preventing siltation in the drainage layer of a landfill. It includes a frame 1, a fixed frame 2 fixed on the frame 1, the fixed frame 2 being funnel-shaped for placing garbage, a guide layer 3 fixed inside the frame 1, and multiple collection pipes 12 fixed at the lower end of the guide layer 3. The collection pipes 12 have arrayed collection holes for discharging leachate. A fixed box 4 is fixed on one side of the frame 1. An unblocking mechanism is provided between the fixed box 4 and the frame 1. The unblocking mechanism includes a reciprocating moving component and a lifting component. A cleaning brush 16 is provided on the reciprocating moving component, and two symmetrical rotating jet nozzles 17 are provided on one side of the cleaning brush 16. The reciprocating moving component drives the cleaning brush 16 and the rotating jet nozzles 17 to move back and forth, and the lifting component drives the cleaning brush 16 and the rotating jet nozzles 17 to move up and down to clean the pipes. The reciprocating moving assembly includes a drain pipe 11 fixed to one end of the collecting pipe 12, one end of the collecting pipe 12 extending out of the frame 1. Both the collecting pipe 12 and the drain pipe 11 are inclined. A moving plate 9 is provided inside the drain pipe 11. A motor 10 is fixed on the moving plate 9. Multiple reciprocating screws 13 are rotatably connected to the moving plate 9. The output end of the motor 10 passes through the moving plate 9 and is fixedly connected to the reciprocating screws 13. The reciprocating screws 13 extend into the collecting pipe 12. The reciprocating screws 13 are fixedly connected to a moving frame 14 by ball nuts. Two symmetrical cleaning columns 15 are provided on the moving frame 14. The cleaning columns 15 are fixedly connected to the cleaning brush 16. A water tank 5 is fixed inside the fixed box 4. A high-pressure water pump 6 is fixed to one side of the water tank 5. A water pipe 7 is fixed to the outlet end of the high-pressure water pump 6. A connecting pipe 8 is fixed to one end of the water pipe 7. Multiple sliding pipes 18 are fixed to the connecting pipe 8. The sliding pipes 18 are fixedly connected to the rotating jet nozzle 17. A cover plate is hinged to the fixed box 4. The movable frame 14 is rotatably connected to the rotating jet nozzle 17 and the cleaning column 15. A protective shell 33 is fixed on the movable plate 9. The reciprocating screw 13 is located inside the protective shell 33. A moving groove is opened on one side of the protective shell 33. The movable frame 14 extends out of the protective shell 33 and is located in the moving groove.

[0023] Specifically, staff transport the garbage to the frame 1 using a transport vehicle. The garbage is contained by a fixed frame 2, which is funnel-shaped to allow leachate to flow into the diversion layer 3. The garbage is blocked by geotextile, filter screen, and gravel layer, allowing the leachate to flow into the diversion layer 3, collect through the collection hole into the collection pipe 12, and then into the drain pipe 11. The collection pipe 12 and the drain pipe 11 are inclined to facilitate the discharge of leachate. The leachate discharged from the drain pipe 11 enters the filter box 34 for filtration, and then is pumped by an external water pump to the treatment device for processing and reuse. The dredging mechanism improves the cleaning effect of the pipes and the diversion layer 3, reduces the recurrence of clogging, facilitates the discharge of leachate, reduces pollution to soil and groundwater, and facilitates the stable operation of the pipes and the diversion layer 3. Specifically, the motor 10 is operated, causing the reciprocating screw 13 to rotate, which in turn causes the ball nut to drive the moving frame 14 to move back and forth within the moving groove. This movement of the moving frame 14 restricts the movement of the cleaning column 15, causing the cleaning brush 16 to move. The two cleaning brushes 16 then move back and forth to clean the collection pipe 12, reducing the residue of particulate impurities and facilitating the discharge of the permeate. Then, the operator adds an appropriate amount of cleaning solution to the water tank 5 and operates the high-pressure water pump 6, allowing the cleaning solution to enter the connecting pipe 8 through the water pipe 7, and then through the connecting pipe 8 into the multi-channel system. A sliding tube 18 causes the rotating jet nozzle 17 to rotate and spray. The moving frame 14 drives the rotating jet nozzle 17 to move back and forth, spraying and cleaning the pipe and the guide layer 3, reducing the blockage of pipe and collection hole by particulate impurities, reducing the accumulation of leachate, and reducing pollution to soil and groundwater. In conjunction with the reciprocating cleaning brush 16, the cleaning effect on the pipe is further improved, reducing cleaning dead corners, reducing repeated blockage of the pipe, and facilitating the discharge of leachate. The reciprocating screw 13 is protected by the protective shell 33 to reduce the impact of particulate matter on the reciprocating screw 13.

[0024] Example 2 Based on Example 1, please refer to Figure 2 , Figure 4 , Figure 5 As shown, a rotating gear 20 is fixed to one end of the cleaning column 15, and a moving rack 21 is fixed to the moving plate 9. The moving rack 21 meshes with the rotating gear 20. The moving plate 9 is fixedly connected to the fixed shell 19, and the moving rack 21 is located inside the fixed shell 19. The fixed shell 19 and the rotating gear 20 are slidably arranged. A high-pressure air pump 24 is fixed inside the fixed box 4. The air outlet of the high-pressure air pump 24 is fixedly connected to the connecting pipe 8. Solenoid valves are fixed to both the air outlet of the high-pressure air pump 24 and the water pipe 7. Two symmetrical cleaning telescopic rods 22 are fixed on the moving frame 14. An arc-shaped scraper 23 is fixed to the telescopic end of the cleaning telescopic rod 22. A spring is fixed inside the cleaning telescopic rod 22. The arc-shaped scraper 23 is adapted to the collection pipe 12. The sliding pipe 18 is a flexible hose.

[0025] Specifically, when the cleaning column 15 moves, the rotating gear 20 moves, causing the rotating gear 20 to rotate on the moving rack 21, thus rotating the cleaning column 15 and causing the cleaning brush 16 to move and rotate, improving the cleaning effect on the pipeline. Then, the high-pressure air pump 24 is operated, allowing high-pressure airflow to enter the sliding tube 18 through the connecting pipe 8 and be sprayed out through the rotating jet nozzle 17 to clean the collection holes on the collection pipe 12, reducing the residue of particulate impurities. The airflow also backwashes the guide layer 3, reducing the blockage of the collection pipe 12 and the guide layer 3, facilitating the discharge of permeate. An additional controller controls the solenoid valve to open or close. The high-pressure water pump 6 and high-pressure air pump 24, through the cleaning telescopic rod 22, drive the arc-shaped scraper 23 to move, scraping and cleaning large particles of debris in the pipe. The cleaning brush 16 further enhances the cleaning effect, facilitating the unblocking of the pipe and the guide layer 3. The spring inside the cleaning telescopic rod 22 causes the arc-shaped scraper 23 to be forced against the collection pipe 12, improving the cleaning effect on the pipe. In conjunction with the rotating jet nozzle 17, the pipe is cleaned after scraping, flushing away residual particles in the pipe, reducing cleaning dead corners, reducing particle residue, reducing repeated blockage of the pipe, facilitating manual cleaning, and ensuring the stable operation of the pipe and the guide layer 3.

[0026] Example 3 Based on Example 1, please refer to Figure 4 , Figure 6 , Figure 7 As shown, a transmission box 25 is provided on one side of the movable plate 9. A bevel gear 26 is fixed on the reciprocating screw 13. A bevel gear 27 is rotatably connected inside the transmission box 25. The bevel gear 26 meshes with the bevel gear 27. An adjusting screw 29 is fixed on the bevel gear 27. A fixing bracket 28 is fixed to the upper end of the drain pipe 11. The adjusting screw 29 extends out of the transmission box 25 and is fixedly connected to the fixing bracket 28 through a ball nut. A filter box 34 is fixed to one end of the drain pipe 11. A limiting telescopic rod 30 is fixed on the movable plate 9. The telescopic end of the limiting telescopic rod 30 is fixedly connected to the drain pipe 11. Multiple sprockets 31 are fixed on one side of the movable plate 9. The sprockets 31 are fixedly connected to the reciprocating screw 13. A chain 32 meshes on the sprockets 31. A protective shell 33 is fixed on one side of the movable plate 9. The sprockets 31 and the chain 32 are all located inside the protective shell 33.

[0027] Specifically, when the reciprocating screw 13 rotates, it causes the first bevel gear 26 to rotate, which in turn drives the second bevel gear 27 to rotate, causing the adjusting screw 29 to rotate. The adjusting screw 29 moves on the fixed frame 28, causing the telescopic rod 30 to extend and retract, thus restricting the moving plate 9. This causes the moving plate 9 and the motor 10 to move up and down reciprocally, which in turn causes the cleaning brush 16 and the rotating jet nozzle 17 to move up and down reciprocally, improving the cleaning effect on the pipeline, reducing cleaning dead angles, reducing particulate residue, reducing repeated clogging of the pipeline, facilitating manual cleaning, and facilitating the stable operation of the pipeline and the guide layer 3. When the motor 10 rotates, it causes the sprocket 31 to rotate, which drives the chain 32 to rotate, causing multiple reciprocating screws 13 to rotate, cleaning multiple collection pipes 12. The sprocket 31 and chain 32 are protected by the protective shell 33.

[0028] The working principle of this invention is as follows: Workers transport garbage to the frame 1 using a transport vehicle. The garbage is contained by a fixed frame 2. The fixed frame 2 is funnel-shaped, which allows leachate in the garbage to flow into the guide layer 3. The garbage is blocked by geotextile, filter screen and gravel layer, allowing the leachate to flow into the guide layer 3, into the collection pipe 12 through the collection hole, and then into the drain pipe 11. The collection pipe 12 and the drain pipe 11 are set at an incline to facilitate the discharge of leachate. The leachate discharged from the drain pipe 11 enters the filter box 34 for filtration, and then is pumped by an external water pump to the treatment device for processing and reuse. Then, the motor 10 is operated, causing the reciprocating screw 13 to rotate, which in turn causes the ball nut to drive the moving frame 14 to move back and forth. The moving frame 14 moves within the moving groove, thus restricting its movement. This causes the cleaning column 15 to drive the cleaning brush 16 to move, resulting in the upper and lower cleaning brushes 16 reciprocating to clean the collection pipe 12, reducing the residue of particulate impurities and facilitating the discharge of the permeate. Then, the operator adds an appropriate amount of cleaning solution to the water tank 5 and operates the high-pressure water pump 6, allowing the cleaning solution to enter the connecting pipe 8 through the water pipe 7. Multiple sliding tubes 18 are inserted, causing the rotating jet nozzle 17 to rotate and spray. The moving frame 14 drives the rotating jet nozzle 17 to move back and forth, spraying and cleaning the pipes and guide layer 3, reducing particulate impurities from clogging the pipes and collection holes, reducing the accumulation of permeate, and reducing pollution to the soil and groundwater. Combined with the reciprocating cleaning brush 16, the cleaning effect on the pipes is further improved, reducing cleaning dead zones and repeated pipe blockage. Then, as the cleaning column 15 moves, the rotating gear 20 moves, driving the rotating gear 20 to move the rack 2. The rotating movement of the cleaning column 15 causes the cleaning brush 16 to rotate, improving the cleaning effect on the pipeline. Then, the high-pressure air pump 24 is operated, allowing high-pressure airflow to enter the sliding tube 18 through the connecting pipe 8 and be sprayed out through the rotating jet nozzle 17 to clean the collection holes on the collection pipe 12, reducing the residue of particulate impurities. The airflow also backwashes the guide layer 3, reducing the blockage of the collection pipe 12 and the guide layer 3, facilitating the discharge of permeate. An additional controller controls the solenoid valve to turn the high-pressure water pump 6 and the high-pressure air pump 24 on or off. Pump 24, through cleaning telescopic rod 22, drives arc-shaped scraper 23 to move, scraping and cleaning large particles of debris in the pipe. In conjunction with cleaning brush 16, the cleaning effect is further improved, which facilitates the unblocking of the pipe and the guide layer 3. Through the spring in the cleaning telescopic rod 22, the arc-shaped scraper 23 is forced to contact the collection pipe 12, which improves the cleaning effect of the pipe. In conjunction with the rotating jet nozzle 17, the pipe is cleaned after scraping, and residual particles in the pipe are flushed, reducing cleaning dead corners, reducing particle residue, and reducing repeated blockage of the pipe. Then, when the reciprocating screw 13 rotates, the first bevel gear 26 rotates, which drives the second bevel gear 27 to rotate, causing the adjusting screw 29 to rotate. The adjusting screw 29 moves on the fixed frame 28, causing the telescopic rod 30 to extend and retract, restricting the moving plate 9, and driving the moving plate 9 and the motor 10 to move up and down reciprocally, causing the cleaning brush 16 and the rotating jet nozzle 17 to move up and down reciprocally, improving the cleaning effect on the pipeline, reducing cleaning dead angles, reducing the residue of particles, reducing repeated clogging of the pipeline, facilitating manual cleaning, and facilitating the stable operation of the pipeline and the guide layer 3. When the motor 10 rotates, the sprocket 31 rotates, driving the chain 32 to rotate, causing multiple reciprocating screws 13 to rotate, cleaning multiple collection pipes 12. The sprocket 31 and chain 32 are protected by the protective shell 33.

[0029] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
