Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, and more specifically, it relates to a landfill leachate denitrification, cleaning, and dosing equipment. Background Technology

[0002] In the field of modern waste management, the treatment of landfill leachate, especially the denitrification process, is a complex and crucial task. Leachate contains various nitrogen oxides, such as organic nitrogen, ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen. Their composition and concentration vary depending on the source of the waste and the treatment method. Denitrification technology is key to preventing eutrophication of water bodies, and its importance is self-evident. However, existing denitrification technologies still face many challenges.

[0003] First, denitrification filters face the problem of incomplete cleaning during actual operation. Traditional filter designs often neglect the effective treatment of sludge and foreign matter, leading to the gradual accumulation of large amounts of sludge and impurities inside the filter. These accumulations not only reduce the treatment efficiency of the filter but may also cause filter media blockage, thus seriously affecting the denitrification effect of the entire system. The accumulation of sludge may also lead to the formation of anaerobic zones, which not only affects the denitrification process but may also generate foul odors, negatively impacting the operating environment. In addition, the presence of foreign matter may damage the equipment and increase maintenance costs. These factors combined significantly reduce the overall efficiency of landfill leachate denitrification equipment, affecting not only treatment quality but also potentially increasing operating costs.

[0004] Secondly, adding carbon and alkali sources is a common practice in the denitrification process. However, the existing pipeline systems have limitations. They are usually designed with a fixed flow rate and lack a flexible adjustment mechanism. This design cannot adapt to changes in demand under different operating conditions. For example, when leachate water quality fluctuates or the treatment load changes, the spraying speed cannot be adjusted in time. This design may lead to the overuse or underuse of carbon and alkali sources, affecting the efficiency and stability of the entire denitrification process. In some cases, improper spraying speed may cause drastic fluctuations in pH, which in turn affects microbial activity and may even lead to the failure of the treatment system.

[0005] Furthermore, although some equipment manufacturers have attempted to address these issues by introducing speed control devices, these solutions are often overly simplistic and fail to adequately consider the complexity of the actual operating environment. These speed control devices typically employ basic mechanical structures, and in actual operation, the equipment may be affected by various external factors, such as pump vibration, pipeline resonance, or even vibrations from the external environment. These factors can all lead to unexpected changes in the adjusted flow rate. Instability in the flow rate not only affects the denitrification effect but may also result in waste or insufficient reagents, increasing operating costs. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a landfill leachate denitrification cleaning and dosing device, which has the following beneficial effects:

[0019] 1. The treatment device solves the problem of incomplete cleaning of denitrification filters in existing technologies through innovative design. The combination of components such as the frame, conveyor belt, and baffles achieves effective separation of sewage and solid waste. The filter holes on the conveyor belt and baffles allow sewage to pass through smoothly while blocking garbage and foreign objects above. The drive motor drives the conveyor belt to move continuously, ensuring that solid waste can be transported to the sewage outlet for discharge in a timely manner. This design not only improves the efficiency of sewage treatment but also greatly reduces the risk of filter clogging and extends the service life of the equipment. At the same time, the rotating spray design of the nozzles and sprayers increases the contact area between sewage and carbon and alkali sources, significantly improving denitrification efficiency.

By rotating the control sleeve, the entire control device can be driven to work, thereby changing the passing volume of carbon and alkali sources and realizing flexible adjustment of delivery and spraying speed. This design can not only adapt to the changing needs under different working conditions, but also ensure the accuracy and stability of the adjustment.

[0021] 3. The ingenious design of the reinforcement mechanism solves the problem of unstable flow rate after adjustment. Combined with components such as plates, limit sleeves, and limit rods, it forms a multi-layered locking system. The design of springs and push springs ensures that each component can automatically reset, increasing the system's reliability and simplifying operation. The design of the arc-shaped groove and clearance hole ensures the stability of the locking. This multi-layered locking mechanism significantly improves the stability after adjustment, effectively preventing flow rate changes caused by factors such as equipment vibration, and extending equipment life. This innovative design not only improves the stability of the equipment but also significantly enhances the accuracy and reliability of adjustment, ensuring the continuous and stable operation of the denitrification process.

The sleeve 11 is threadedly fitted onto the outside of the adjusting rod 10. A reinforcing mechanism is provided on the outside of the fixed tube 6. The reinforcing mechanism includes a mating plate 12, a limiting sleeve 13, a limiting rod 14, a clearance hole 15, a spring 16, a return block 17, a connecting block 18, an arc groove 19, and a limiting plate 20. The mating plate 12 is rotatably fitted onto the outside of the fixed tube 6, the limiting sleeve 13 is slidably fitted onto the outside of the fixed tube 6, the limiting rod 14 is connected to one side of the limiting sleeve 13, the clearance hole 15 is opened at one end of the arc groove 19, the two ends of the spring 16 are respectively connected to the return block 17 and the connecting block 18, the return block 17 is fixedly connected to one side of the mating plate 12, the connecting block 18 is fixedly connected to the outside of the fixed tube 6, the arc groove 19 is opened on the mating plate 12, and the limiting plate 20 is fixedly set on the limiting rod 14.

[0035] A connecting rod 21 is provided on the inner side of the corresponding fixed tube 6 and the control sleeve 3. The prism sleeve 9 is connected to the inner wall of the control sleeve 3 through the connecting rod 21, and the outer side of the adjusting sleeve 11 is connected to the inner wall of the corresponding fixed tube 6 through the connecting rod 21.

[0036] A push spring 22 is connected to one side of the limiting sleeve 13. The push spring 22 is sleeved on the outside of the limiting rod 14, and the other end of the push spring 22 is in contact with the mating plate 12.

[0037] The outer wall of the fixed tube 6 is provided with a positioning groove 23, the side wall of the control sleeve 3 is provided with a positioning rod 24, and the outer wall of the control sleeve 3 is connected with a return spring 25. One end of the positioning rod 24 is inserted into the positioning groove 23, and the other end of the positioning rod 24 is connected to the outer wall of the control sleeve 3 through the return spring 25.

[0038] In this embodiment, when it is necessary to adjust the conveying speed and spraying speed of the carbon source and alkali source, the mating plate 12 is first rotated, causing the mating plate 12 to move the clearance hole 15 and the arc groove 19. At the same time, the mating plate 12 will move the return block 17 connected on one side. Then, the return block 17 will cooperate with the connecting block 18 to compress the spring 16. When the spring 16 is compressed to its limit, the clearance hole 15 will be concentric with the limiting plate 20. Then, the limiting sleeve 13 is pushed, and the limiting sleeve 13 will drive the limiting rod 14 and the limiting plate 20 to pass through the clearance hole 15. At the same time, the limiting sleeve 13 will cooperate with the mating plate 12 to compress the push spring 22. When the push spring 22 is compressed to its limit, the corresponding limiting plate 20 will pass through the clearance hole 15 and reach the other side of the mating plate 12. Then, the mating plate 12 is released, causing the spring 16 to push the return block 17 to reset. The return block 17 then drives the mating plate 12 to rotate and reset. The mating plate 12 then drives the arc groove 19 and the clearance hole 15 to reset. The limiting rod 14 then enters the arc groove 19. At the same time, the limiting sleeve 13 is limited to one side of the mating plate 12 through the cooperation of the limiting rod 14 and the corresponding limiting plate 20. At this time, the outer side of the positioning rod 24 loses the limitation of the inner wall of the limiting sleeve 13. Then, the control sleeve 3 is rotated, and the control sleeve 3 drives the positioning rod 24 to move. Then, the side wall of the positioning groove 23 presses against one end of the positioning rod 24. Due to the rounded corner structure of the edge of the positioning groove 23 and the end of the positioning rod 24, one end of the positioning rod 24 slides out of the positioning groove 23. The other end of the positioning rod 24 will cause the return spring 25 to stretch. At the same time, the control sleeve 3 will drive the prism sleeve 9 to rotate through the connecting rod 21. Then the prism sleeve 9 will drive the prism rod 8 to rotate. Then the prism rod 8 will drive the adjusting rod 10 and the blocking rod 7 to rotate. Since the adjusting sleeve 11 and the adjusting rod 10 are connected by threads, and the adjusting sleeve 11 will not rotate, the adjusting rod 10 will move spirally along the threads on the inner side of the adjusting sleeve 11. Then the adjusting rod 10 will drive the prism rod 8 to slide along the prism sleeve 9. Then the prism rod 8 will drive the blocking rod 7 to slide in the flow pipe 4, which will change the number of open flow holes 5, thereby changing the volume of carbon source and alkali source passing through, and thus changing the delivery speed and spraying speed of carbon source and alkali source. The purpose is to adjust the control sleeve 3 until it is properly adjusted, then stop rotating it and allow the return spring 25 to engage the positioning rod 24 into the corresponding positioning groove 23. Then, rotate the mating plate 12 again, causing it to push the return block 17 against the spring 16. Simultaneously, the mating plate 12 will move the arc-shaped groove 19 and the clearance hole 15. When the clearance hole 15 moves to a position concentric with the limit plate 20, the push spring 22 will push the limit sleeve 13 to reset. Then, the limit sleeve 13 will move the limit rod 14 and the limit plate 20 to reset. After the push spring 22 has fully reset, release the mating plate 12. The spring 16 will push the return block 17 to reset the mating plate 12. Then, the mating plate 12 will move the arc-shaped groove 19 and the clearance hole 15 to a position not corresponding to the limit rod 14.At this point, the limiting rod 14 and the mating plate 12 cooperate to form a stable limit on the limiting sleeve 13, preventing the limiting sleeve 13 from sliding. Then, the inner wall of the limiting sleeve 13 again limits the outer end of the positioning rod 24, preventing the positioning rod 24 from moving. Then, the positioning rod 24 and the positioning groove 23 cooperate to form a limit on the control sleeve 3, preventing the control sleeve 3 from rotating, thereby ensuring the stability after the flow rate adjustment.

[0039] Please see Figures 1-5 As one embodiment of the processing device: the processing device includes a frame 26, a feed pipe 27, a mounting chamber 28 and a through hole 29. The frame 26 is installed above the processing box 1, the feed pipe 27 is connected above the mounting chamber 28, and the through hole 29 is opened at the bottom of the mounting chamber 28.

[0040] A drive roller 30 is movably installed inside the frame 26. A conveyor belt 31 is sleeved on the outside of the drive roller 30. A partition 32 is connected to the outside of the conveyor belt 31. Filter holes 33 are opened on both the partition 32 and the conveyor belt 31. A drive motor 34 is detachably installed on one side of the frame 26. The output end of the drive motor 34 is connected to one end of one of the drive rollers 30. A limit wheel 35 is movably installed inside the frame 26. A drain port 36 is opened on one side of the frame 26.

[0041] The treatment box 1 is equipped with a spray pipe 37, and a nozzle 38 is connected to the outside of the spray pipe 37. One end of the spray pipe 37 is connected to the corresponding fixed pipe 6, and the spray pipe 37 and the fixed pipe 6 are rotatably connected. The other end of the spray pipe 37 is connected to the output end of the reduction motor 39. The reduction motor 39 is detachably installed on one side of the treatment box 1.

[0042] A storage tank 40 is installed on one side of the processing tank 1, a conveying pump 41 is installed on one side of the storage tank 40, a conveying pipe 42 is installed on one side of the fixed base 2, the input end of the conveying pump 41 is connected to the bottom of the storage tank 40, the output end of the conveying pump 41 is connected to one end of one of the fixed pipes 6 through the conveying pipe 42, and a discharge pipe 43 is connected to one side of the processing tank 1.

[0043] More specifically, when the equipment is needed, first connect the output end of the external conveying equipment to the feed pipe 27. Then, sewage and foreign objects are conveyed into the installation chamber 28 through the feed pipe 27. Next, turn on the drive motor 34 installed on one side of the frame 26. The drive motor 34 drives the transmission roller 30 connected to the output end to rotate. The transmission roller 30 then drives the outer conveyor belt 31 to run. At the same time, the conveyor belt 31 drives the partition 32 to move. Sewage flows through the filter holes 33 on the conveyor belt 31 and the partition 32 to the bottom of the installation chamber 28. Meanwhile, garbage and foreign objects are blocked above the conveyor belt 31. The partition 32 then drives the garbage and foreign objects to move along the conveyor belt 31. When they reach the drain port 36 on one side of the frame 26... When the wastewater enters the bottom of the installation chamber 28, it will fall into the collection device of the external equipment through the drain outlet 36. At this time, the wastewater will enter the treatment tank 1 through the through hole 29. Then, the transfer pump 41 is turned on, and the transfer pump 41 extracts the carbon source and alkali source stored in the storage tank 40 and transports them to the spray pipe 37 through the transfer pipe 42 connected to the output end of the transfer pump 41. Then, it is atomized and sprayed out through the nozzle 38 connected to the outside of the spray pipe 37. At the same time, the reduction motor 39 installed on one side of the treatment tank 1 is turned on, and the reduction motor 39 drives the spray pipe 37 to rotate. Then, the spray pipe 37 drives the nozzle 38 to rotate, realizing all-round rotational spraying, increasing the contact area between the wastewater and the carbon source and alkali source, thereby accelerating the treatment efficiency. The treated wastewater will be transported to the next process for further treatment through the discharge pipe 43.

[0044] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the conveying speed and spraying speed of the carbon source and alkali source, firstly rotate the mating plate 12, causing the mating plate 12 to move the clearance hole 15 and the arc groove 19. At the same time, the mating plate 12 will move the return block 17 connected on one side. Then, the return block 17 will cooperate with the connecting block 18 to compress the spring 16. When the spring 16 is compressed to its limit, the clearance hole 15 will be concentric with the limiting plate 20. Then, push the limiting sleeve 13. The limiting sleeve 13 will drive the limiting rod 14 and the limiting plate 20 through the clearance hole 15. At the same time, the limiting sleeve 13 will cooperate with the mating plate 12 to compress the push spring 22. When the push spring 22 is compressed to its limit, the corresponding limiting plate 20 will just pass through the clearance hole 15 and reach the mating hole 15. On the other side of the mating plate 12, the mating plate 12 is released, causing the spring 16 to push the return block 17 to reset. The return block 17 then drives the mating plate 12 to rotate and reset. The mating plate 12 then drives the arc groove 19 and the clearance hole 15 to reset. The limiting rod 14 then enters the arc groove 19. At the same time, the limiting sleeve 13 is limited to one side of the mating plate 12 through the cooperation of the limiting rod 14 and the corresponding limiting plate 20. At this time, the outer side of the positioning rod 24 loses the limitation of the inner wall of the limiting sleeve 13. Then, the control sleeve 3 is rotated, and the control sleeve 3 drives the positioning rod 24 to move. Then, the side wall of the positioning groove 23 presses against one end of the positioning rod 24. Due to the rounded corner structure of the edge of the positioning groove 23 and the end of the positioning rod 24, one end of the positioning rod 24 slides out of the positioning groove 23. Simultaneously, the other end of the positioning rod 24 will cause the return spring 25 to stretch. At the same time, the control sleeve 3 will drive the prism sleeve 9 to rotate via the connecting rod 21. Then, the prism sleeve 9 will drive the prism rod 8 to rotate. Then, the prism rod 8 will drive the adjusting rod 10 and the blocking rod 7 to rotate. Since the adjusting sleeve 11 and the adjusting rod 10 are connected by threads, and the adjusting sleeve 11 will not rotate, the adjusting rod 10 will move spirally along the threads on the inner side of the adjusting sleeve 11. Then, the adjusting rod 10 will drive the prism rod 8 to slide along the prism sleeve 9. Then, the prism rod 8 will drive the blocking rod 7 to slide in the flow pipe 4, thereby changing the number of open flow holes 5, thus changing the volume of carbon source and alkali source passing through, thereby changing the delivery speed and spraying of carbon source and alkali source. The purpose of adjusting the speed is to stop rotating the control sleeve 3 after it is properly adjusted, so that the return spring 25 drives the positioning rod 24 to engage in the corresponding positioning groove 23. Then, rotate the mating plate 12 again, so that the mating plate 12 drives the return block 17 to press against the spring 16. At the same time, the mating plate 12 will drive the arc groove 19 and the clearance hole 15 to move. When the clearance hole 15 moves to a position concentric with the limit plate 20, the push spring 22 will push the limit sleeve 13 to reset. Then, the limit sleeve 13 will drive the limit rod 14 and the limit plate 20 to reset. After the push spring 22 has fully reset, release the mating plate 12. The spring 16 will push the return block 17 to reset the mating plate 12. Then, the mating plate 12 will drive the arc groove 19 and the clearance hole 15 to a position that does not correspond to the limit rod 14.At this point, the limiting rod 14 and the mating plate 12 cooperate to form a stable limit on the limiting sleeve 13, preventing the limiting sleeve 13 from sliding. Then, the inner wall of the limiting sleeve 13 again limits the outer end of the positioning rod 24, preventing the positioning rod 24 from moving. Then, the positioning rod 24 and the positioning groove 23 cooperate to form a limit on the control sleeve 3, preventing the control sleeve 3 from rotating, thereby ensuring the stability after the flow rate adjustment.

[0045] When the equipment is needed, first connect the output end of the external conveying equipment to the feed pipe 27. Then, sewage and foreign objects are conveyed into the installation chamber 28 through the feed pipe 27. Next, turn on the drive motor 34 installed on one side of the frame 26. The drive motor 34 drives the transmission roller 30 connected to the output end to rotate. The transmission roller 30 then drives the outer conveyor belt 31 to run. At the same time, the conveyor belt 31 drives the partition 32 to move. Sewage flows through the filter holes 33 on the conveyor belt 31 and the partition 32 to the bottom of the installation chamber 28. Meanwhile, garbage and foreign objects are blocked above the conveyor belt 31. The partition 32 then drives the garbage and foreign objects to move along the conveyor belt 31. When they reach the drain port 36 on one side of the frame 26, they will be discharged. Wastewater falling through the drain outlet 36 into the external collection device will then enter the treatment tank 1 through the through hole 29 at the bottom of the installation chamber 28. At this time, the transfer pump 41 is turned on, and the carbon source and alkali source stored in the storage tank 40 are extracted and transported to the spray pipe 37 through the transfer pipe 42 connected to the output end of the transfer pump 41. Then, the wastewater is atomized and sprayed out through the nozzle 38 connected to the outside of the spray pipe 37. At the same time, the reduction motor 39 installed on one side of the treatment tank 1 is turned on, and the reduction motor 39 drives the spray pipe 37 to rotate. The spray pipe 37 then drives the nozzle 38 to rotate, realizing all-round rotational spraying, increasing the contact area between the wastewater and the carbon source and alkali source, thereby accelerating the treatment efficiency. The treated wastewater will be transported to the next process for further treatment through the discharge pipe 43.
