Description

Technical Field

[0001] This invention belongs to the field of waste composting technology, specifically a waste composting auxiliary aeration device and its usage method. Background Technology

[0002] Composting aims to transform agricultural waste, municipal sludge, and other organic waste into stable, harmless humic organic fertilizer through aerobic fermentation by microorganisms, achieving volume reduction, harmlessness, and resource utilization. Traditional composting often suffers from insufficient oxygen supply, leading to localized anaerobic conditions, producing malodorous gases such as hydrogen sulfide, and also has a long fermentation cycle and uneven maturation. Introducing a ventilation device to forcibly fill the waste pile with air can significantly improve composting efficiency: on the one hand, it ensures the oxygen needs of aerobic microorganisms, accelerating the degradation rate of organic matter; on the other hand, it promotes heat and moisture loss, preventing overheating of the pile and inhibition of microbial activity, while also removing volatile odorous substances and reducing secondary pollution.

[0003] Significant drawbacks exist when handling materials containing fine slag and debris: under the compaction of the pile, fine slag is easily squeezed into and retained inside the air injection port, while accumulating at the air outlet to form a dense filter cake layer, causing physical blockage. This not only leads to a surge in airflow resistance and severely uneven air distribution, but can even cause pipeline paralysis. Furthermore, because the fine slag is tightly embedded, conventional methods are difficult to use to clear the blockage, resulting in high operation and maintenance costs.

[0004] Therefore, the present invention provides an auxiliary aeration device for waste composting and a method of using it. Summary of the Invention

[0014] Preferably, a sealing ring is fixedly connected to the inner wall of the telescopic groove, the sealing ring is sleeved on the outer side of the telescopic block, and its inner wall is tightly fitted to the outer side of the telescopic block.

[0015] A method for using a waste composting auxiliary aeration device, applicable to the aforementioned waste composting auxiliary aeration device, includes the following steps: S1: When not injecting air, use the movable cover to seal the air injection tank. When injecting air, remove the movable cover from above the air injection tank. S2: After use, start motor one to make the cleaning plate rotate to wipe and clean the foreign objects attached to the filter screen, so that the foreign objects are loosened on the filter screen; S3: After wiping and cleaning, activate the electric push rod two to move the scraper on the vent pipe and scrape away foreign objects from the vent pipe and filter screen.

[0016] The beneficial effects of this invention are as follows: 1. In the initial state of this invention, the movable cover covers the filter screen, preventing direct contact between the compost residue and the filter screen. During gas injection, an electric push rod drives the movable cover to move horizontally, exposing the filter screen, allowing gas to pass through the screen and enter the compost pile. After gas injection, the movable cover returns to its original position, and a motor is started to rotate the cleaning plate. Combined with the telescopic traction of the electric push rod, the outer wall of the ventilation pipe and the surface of the filter screen are thoroughly wiped, loosening fine debris. A scraper then collects and removes the loosened foreign matter. This design effectively solves the problems of easy clogging of the gas injection port and uneven airflow or even pipeline paralysis caused by biofilm scaling in traditional devices. Online cleaning can be completed without disassembling the pipeline, significantly reducing maintenance frequency and costs. At the same time, it ensures uniform gas distribution and ventilation efficiency, extends the service life of the device, and improves the stability and automation level of the composting process.

[0017] 2. When cleaning the filter screen, some fine debris may pass through the screen and fall into the pipe. After cleaning, start motor two to drive the take-up and release shaft to rotate, winding up the take-up and release rope, and pulling the dust pusher plate to move along the pipe axis, gathering the scattered mud, sand, fibers, and other foreign objects towards the insertion ring; at the same time, the rubber elastic band is stretched and stores energy. After cleaning, simply release the limit of the insertion ring to remove the foreign objects from the vent pipe. This design realizes the mechanized cleaning of foreign objects accumulated inside the venting device, avoiding the high-intensity work of manually disassembling and unblocking the pipe, effectively preventing airway blockage and increased airflow resistance caused by sludge accumulation in the pipe, and further improving the maintenance-free cycle and long-term operational reliability of the device.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 5 and Figure 7 and Figure 8 As shown in the figure, an auxiliary aeration device for waste composting according to an embodiment of the present invention includes an aeration pipe 1, one end of which is sealed, and an aeration groove 2 is provided at the top of the aeration pipe 1. The air injection groove 2 is movably inserted with a connector frame 6, and a filter screen 7 is fixedly connected inside the connector frame 6. The connector frame 6 is flush with the outer side of the air pipe 1. A pair of symmetrically distributed connecting blocks 3 are fixedly connected to the outside of the ventilation pipe 1. An electric push rod 4 and a drive controller 1 are fixedly connected to the side of the connecting block 3. The same movable cover 5 is fixedly connected to the telescopic ends of the pair of electric push rods 4. The inner wall of the movable cover 5 abuts against the outer side of the vent pipe 1. An arc-shaped groove 8 is provided on the inner top wall of the movable cover 5. An electric push rod 2 9 and a drive controller 2 are fixedly connected to the inner side wall of the arc-shaped groove 8. A connecting plate 10 is fixedly connected to the telescopic end of the electric push rod 2 9. Several motors 11 and a start / stop controller are fixedly connected to the inner wall of the connecting plate 10. A cleaning plate 12 is fixedly connected to the output end of the motors 11. There is a gap between the top of the cleaning plate 12 and the bottom of the connecting plate 10. The bottom of the cleaning plate 12 abuts against the top of the vent pipe 1. A pair of round blocks 13 are fixedly connected to the side of the connecting plate 10. A scraper 14 is fixedly connected to the side of the round blocks 13 away from the connecting plate 10. The bottom of the scraper 14 abuts against the outside of the vent pipe 1.

[0023] Existing technologies have significant drawbacks when processing materials containing fine slag and debris: under the compaction of the pile, fine slag is easily squeezed into and retained inside the air injection port, while accumulating at the air outlet to form a dense filter cake layer, causing physical blockage. This not only leads to a surge in airflow resistance and severely uneven air distribution, but can even cause pipeline failure. Furthermore, because the fine slag is tightly embedded, conventional methods are difficult to use to clear the blockage, resulting in high operation and maintenance costs. The present invention is used in the following steps: Step 1: In the initial state, the position of the movable cover 5 is as follows: Figure 1 As shown, the movable cover 5 is used to cover the filter screen 7 to prevent foreign objects from adhering to the filter screen 7; When injecting gas, start the electric push rod 4, and its telescopic end pulls the movable cover 5 to the side closer to the connecting block 3 until the movable cover 5 is removed from the filter screen 7. Then inject gas into the vent pipe 1, so that the gas passes through the filter screen 7 and enters the waste. Step 2: After the air injection is completed, start the electric push rod 4 again to push the movable cover 5 back to its original position. At this time, a certain amount of foreign matter will adhere to the surface of the filter screen 7 and the outside of the air pipe 1 near the filter screen 7. To remove foreign objects, motor 11 needs to be started, so that its output end drives the cleaning plate 12 to rotate on the outside of the vent pipe 1. Then, electric push rod 9 is started, so that its telescopic end pulls the connecting plate 10 and all its mechanisms to move together. Thus, the cleaning plate 12 is used to wipe and clean different positions on the vent pipe 1 and the filter screen 7, so that the foreign objects are loosened. After loosening the foreign objects using the cleaning plate 12, the scraper 14 is used to push away the loosened foreign objects and pile them up, thereby cleaning the surface of the filter screen 7 and preventing it from becoming clogged.

[0024] In summary, in the initial state, the movable cover 5 covers the filter screen 7, preventing direct contact between the compost residue and the filter screen 7. During gas injection, the electric push rod 4 drives the movable cover 5 to move horizontally, exposing the filter screen 7, allowing gas to pass through the screen and enter the compost pile. After gas injection, the movable cover 5 returns to its original position, and the motor 11 starts to rotate the cleaning plate 12. Combined with the telescopic traction of the electric push rod 9, the outer wall of the ventilation pipe 1 and the surface of the filter screen 7 are thoroughly wiped, loosening fine debris. The scraper 14 then collects and removes the loosened foreign matter. This design effectively solves the problems of easy clogging of the gas injection port and uneven airflow or even pipeline paralysis caused by biofilm scaling in traditional devices. Online cleaning can be completed without disassembling the pipeline, significantly reducing maintenance frequency and costs. Simultaneously, it ensures uniform gas distribution and ventilation efficiency, extends the service life of the device, and improves the stability and automation level of the composting process.

[0025] like Figure 4 and Figure 6 As shown, a dust suction hole 15 is provided on the inner top wall of the arc-shaped groove 8. The interior of the movable cover 5 is a hollow structure. An air pump and a dust suction controller are installed inside the movable cover 5. The dust suction hole 15 is connected to the interior of the movable cover 5. The bottom of the movable cover 5 is provided with a pair of symmetrically distributed dust outlet grooves 18. A pair of symmetrically distributed rectangular blocks 16 are fixedly connected to the inner wall of the dust outlet grooves 18. The bottom of the pair of rectangular blocks 16 is fixedly connected to the same sealing plate 17 by fasteners. The sealing plate 17 is movably inserted into the inside of the dust outlet grooves 18. The dust outlet grooves 18 are connected to the inside of the movable cover 5. There is a gap between the dust suction hole 15 and the outside of the ventilation pipe 1. When cleaning the filter screen 7, the air pump can be started to suck up air so that the scraped foreign objects can pass through the dust suction hole 15 and enter the interior of the movable cover 5. Finally, the sealing plate 17 is removed from the dust outlet 18 at regular intervals so that the collected foreign objects can be removed from the dust outlet 18. This makes it easy to remove foreign objects from the filter screen 7 and the air pipe 1 in a timely manner and greatly improves the convenience of personnel to remove foreign objects.

[0026] like Figure 1 As shown, an alarm 19 is fixedly connected to the top of the movable cover 5. An alarm controller and a dust collection sensor are installed inside the movable cover 5. Both the alarm 19 and the dust collection sensor are electrically connected to the alarm 19 via wires. Once a set amount of foreign objects has been collected inside the movable enclosure 5, the alarm 19 will emit an audible signal to remind personnel to remove the foreign objects from the movable enclosure 5 in a timely manner.

[0027] like Figure 3As shown, a pair of symmetrically distributed insertion slots 20 are provided on the inner wall of the air injection groove 2, and a pair of mounting blocks 21 that are adapted to the insertion slots 20 are fixedly connected to the outer side of the insertion frame 6. The mounting blocks 21 are installed in the insertion slots 20 by fasteners. The fastener is a bolt. After the plug frame 6 is inserted into the air injection groove 2, the mounting block 21 will enter the plug groove 20. Then, the mounting block 21 is fixed in the plug groove 20 using bolts, thereby fixing the plug frame 6 in the plug groove 20.

[0028] like Figure 4 As shown, a sealing frame 22 is fixedly connected to the inner wall of the movable cover 5, and the bottom of the sealing frame 22 is tightly fitted to the outer side of the vent pipe 1. The sealing frame 22 can improve the sealing between the movable cover 5 and the vent pipe 1, preventing foreign objects from coming into contact with the filter screen 7 through the connection between the two.

[0029] like Figure 2 As shown, a fixing groove is provided on the outer side of the vent pipe 1, and an annular plate 23 is fixedly connected inside the fixing groove. Friction patterns are engraved on the top of the annular plate 23, and the outer side of the annular plate 23 is flush with the outer side of the vent pipe 1. After the foreign matter is collected into the moving hood 5, the cleaning plate 12 and the scraper 14 are moved over the annular plate 23. The annular plate 23 is used to scrape off the foreign matter attached to the bottom of the two plates, improving their cleanliness. Then, the foreign matter scraped off from the bottom of the two plates is sucked into the moving hood 5 for temporary storage.

[0030] like Figure 8 and Figure 9 As shown, a connecting frame 24 is fixedly connected to the inner wall of the plug frame 6. An air blowing hole 25 is opened on the side of the connecting frame 24 near the filter screen 7. A cavity is opened inside the connecting frame 24. An air pump and an air blowing controller are installed inside the cavity. The cavity is connected to the air blowing hole 25. During the process of gas passing through filter screen 7 and moving into the waste residue, air pump 2 can be started to blow air into the cavity. Then the gas will move out from the air blowing hole 25 and spray onto filter screen 7, thereby clearing filter screen 7 by reverse blowing, so that it is not easily blocked by foreign objects during the air injection process.

[0031] Example 2: Figure 10-12As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plug-in ring 26 is movably inserted inside the vent pipe 1, a pair of symmetrically distributed telescopic grooves 27 are opened on the outer side of the plug-in ring 26, one end of a pair of springs 28 is fixedly connected to the inner wall of the telescopic groove 27, the other end of the pair of springs 28 is fixedly connected to the same telescopic block 29, and a pair of limiting grooves 30 adapted to the telescopic block 29 are opened on the inner wall of the vent pipe 1; The insertion ring 26 has an internal mounting cavity, which contains an air pump and a mounting controller. The mounting cavity communicates with the telescopic groove 27. A pair of symmetrically distributed semicircular blocks 35 are fixedly connected to the side of the plug ring 26. A motor 36 and a winding controller are fixedly connected to one of the semicircular blocks 35. A take-up and release shaft 37 is fixedly connected to the output end of the motor 36. The take-up and release shaft 37 is rotatably connected between the pair of semicircular blocks 35. One end of a pair of take-up and release ropes 31 is fixedly connected to the take-up and release shaft 37. The other end of the pair of take-up and release ropes 31 is fixedly connected to the same dust pusher plate 32. The inner wall of the vent pipe 1 is provided with several round holes 33. One end of a rubber elastic band 34 is fixedly connected to the inner wall of the round hole 33. The other end of the rubber elastic band 34 is fixedly connected to the dust pusher plate 32. In the initial state, the rubber elastic band 34 is at its original length. When the telescopic block 29 enters the limiting groove 30, the spring 28 is in a stretched state.

[0032] When using this invention, the insertion ring 26 is inserted into the vent pipe 1, and the air pump 3 is started to inject air into the telescopic groove 27, so that the gas pushes one side of the telescopic block 29 into the limiting groove 30, thereby improving the stability of the insertion ring 26 in the vent pipe 1. During the cleaning process of filter screen 7, a certain amount of foreign objects will pass through filter screen 7 and fall into ventilation pipe 1. After cleaning filter screen 7, motor 2 36 needs to be started so that its output end drives the take-up and release shaft 37 to rotate and take up the take-up and release rope 31, thereby causing the take-up and release rope 31 to pull the dust pusher plate 32 to move together towards the plug ring 26. When the dust pusher plate 32 moves, it will push the foreign objects in the vent pipe 1, causing the foreign objects to gather together and move towards the insertion ring 26. At the same time, the rubber elastic band 34 will be stretched by the dust pusher plate 32. Finally, remove the foreign object from the vent pipe 1. After removal, rotate the motor 2 36 so that the rubber elastic band 34 pulls the dust pusher 32 back to its original position.

[0033] In summary, during the cleaning of filter screen 7, some fine debris will pass through the screen and fall into the pipe. After cleaning, the second motor 36 is started to drive the take-up and release shaft 37 to rotate, winding up the take-up and release rope 31, which pulls the dust pusher plate 32 to move along the pipe axis, gathering the scattered mud, sand, fibers and other foreign objects towards the insertion ring 26; at the same time, the rubber elastic band 34 is stretched and stores energy. After cleaning, simply release the limit of the insertion ring 26 to remove the foreign objects from the vent pipe 1. This design realizes the mechanized cleaning of foreign objects accumulated inside the venting device, avoiding the high-intensity work of manually dismantling and unblocking the pipe, effectively preventing airway blockage and increased airflow resistance caused by sludge accumulation in the pipe, and further improving the maintenance-free cycle and long-term operational reliability of the device.

[0034] like Figure 11 As shown, a sealing ring is fixedly connected to the inner wall of the telescopic groove 27. The sealing ring is sleeved on the outer side of the telescopic block 29, and its inner wall is tightly fitted to the outer side of the telescopic block 29. The sealing ring can improve the sealing performance of the telescopic block 29 in the telescopic groove 27 and prevent air leakage at the connection between the two.

[0035] like Figure 13 As shown, a method for using a waste composting auxiliary aeration device, applicable to the aforementioned waste composting auxiliary aeration device, includes the following steps: S1: When not injecting air, use the movable cover 5 to seal the air injection groove 2. When injecting air, remove the movable cover 5 from above the air injection groove 2. S2: After use, start motor 11 to make cleaning plate 12 rotate to wipe and clean the foreign objects attached to filter screen 7, so that the foreign objects are loosened on filter screen 7. S3: After wiping and cleaning, start the electric push rod 29 to move the scraper 14 on the air pipe 1 to scrape away foreign objects on the air pipe 1 and the filter screen 7. S4: After cleaning the filter screen 7, start the motor 2 36 to wind up the take-up rope 31, so that the dust pusher 32 moves inside the vent pipe 1 to push the foreign objects that have fallen from the filter screen 7 into the vent pipe 1 toward the opening end of the vent pipe 1, and then remove the foreign objects.
