Description

Technical Field

[0001] This invention relates to the field of composting fermentation technology, specifically to a high-efficiency composting fermentation device for treating agricultural and livestock solid waste. Background Technology

[0002] Composting and fermentation of agricultural and livestock solid waste (such as livestock and poultry manure, straw, and livestock wastewater residue) is a key technology for realizing resource utilization. Its core is to transform organic matter into humus-rich organic fertilizer through microbial metabolism. However, existing composting and fermentation devices often suffer from frequent bottom-layer decay problems due to material characteristics (high moisture content, easy compaction) and insufficient environmental control. Furthermore, it is difficult to accurately process materials from different areas, seriously affecting composting efficiency and product quality.

[0003] Current high-efficiency composting fermentation devices for agricultural and livestock solid waste treatment typically use a monolithic fermentation tank without internal layering or isolation design. Due to gravity, agricultural and livestock solid waste accumulates at the bottom first, easily forming an anaerobic environment due to high compaction and poor aeration, leading to the putrefaction of the bottom material. Because of the lack of a separating structure, solid particles of putrefied material can spread to the middle and upper layers with the stirring device, contaminating the normal fermentation area, resulting in a decline in the overall quality of the material in the tank, and even requiring complete emptying, causing resource waste and efficiency loss. Furthermore, the putrefied material at the bottom of the fermentation tank is in close contact with the tank bottom, and the leachate is trapped by the material and cannot flow, resulting in poor leachate drainage and affecting subsequent composting treatment.

[0004] To address the above issues, a highly efficient composting and fermentation device for treating agricultural and livestock solid waste is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency composting fermentation device for treating agricultural and livestock solid waste. By using this device, the problems mentioned above are solved, such as the lack of a separation structure, which causes solid particles of decaying materials to diffuse to the middle and upper layers with the stirring device, polluting the normal fermentation area and resulting in poor leachate discharge.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency composting fermentation device for treating agricultural and livestock solid waste includes a fermentation tank. Three gas sensors at different heights are installed through the surface of the fermentation tank. A driving agitator is installed inside the fermentation tank. Two pushing components at different heights are installed on the surface of the driving agitator, and both pushing components are slidably connected to the fermentation tank. An isolation membrane is installed on one side of each pushing component. Two sealing components corresponding to the isolation membrane are installed inside the fermentation tank, with one end of each sealing component penetrating and connected to one side of the fermentation tank. A hollow tube is fixedly installed at one end of the driving agitator and rotatably connected to the bottom of the fermentation tank. A filter plate is sleeved on the surface of the hollow tube and contacts the bottom of the fermentation tank. A lifting component is fixedly installed at one end of the fermentation tank, with its output end slidably connected to the hollow tube and attracting the filter plate. Cleaning components are fixedly installed on the surface of the hollow tube and contact the bottom of the fermentation tank and the filter plate. A discharge hole is opened through one end of the fermentation tank.

[0008] Furthermore, the fermenter has three viewing doors at different heights on its surface, a discharge door near the bottom, four horizontal plates inside, and a support plate at the bottom.

[0009] Furthermore, the driving stirring component includes a support frame and a motor fixed inside the support frame. The support frame is fixedly connected to the fermentation tank, and a shaft is fixedly installed at the output end of the motor. The shafts are rotatably connected to the fermentation tank and the support plate. Two sets of threaded grooves are correspondingly provided on the surface of the shafts, and three stirring rods are respectively installed on the surface of the shafts.

[0010] Furthermore, the pushing component includes a first support seat and a second support seat disposed on the surface of the shaft. Both ends of the isolation membrane are fixedly connected to the first support seat and the second support seat. The first support seat is in contact with the surface of the shaft. A plurality of first connecting rods are rotatably connected to the surface of the first support seat. A second connecting rod is hinged to one end of each first connecting rod, and one end of the second connecting rod is rotatably connected to the second support seat. A protective cylinder is installed on one side of both the first and second support seats. The protective cylinders are slidably connected to the shaft and the cross plate. Limiting rods are fixedly installed on both sides of the protective cylinders. Both limiting rods are slidably connected to the cross plate.

[0011] Furthermore, a first housing is fixedly installed on one side of the first support base. The first housing is slidably connected to the shaft. A first electromagnet is installed inside the first housing. A first threaded plate is slidably connected inside the first housing. A first magnet block is fixedly installed on one side of the first threaded plate. Several first springs are fixedly installed on one side of the first threaded plate and are fixedly connected to the first housing. Two hooks are fixedly installed on one side of the first housing.

[0012] Furthermore, a second housing is fixedly installed on one side of the second support base. The second housing is slidably connected to the shaft. A second electromagnet is installed inside the second housing. A second threaded plate is slidably connected inside the second housing. A second magnet block is fixedly installed on one side of the second threaded plate. Several second springs are fixedly installed on one side of the second threaded plate and are fixedly connected to the second housing. Two vertical plates are installed inside the second housing. L-shaped rods are fixedly installed on both sides of the second threaded plate and are slidably connected to the second housing. A support rod is fixedly installed at one end of the L-shaped rod. The support rods are slidably connected to the two vertical plates. Two rectangular holes corresponding to the hooks are opened through one side of the second housing.

[0013] Furthermore, the sealing element includes a concave circular plate and a circular air bladder installed inside the concave circular plate. A connecting pipe is connected to one side of the circular air bladder, and the connecting pipes are all connected through the concave circular plate and one side of the fermentation tank. One end of the connecting pipe is connected to an air pump, and a solenoid valve is installed on the surface of the connecting pipe.

[0014] Furthermore, permanent magnet sheets are installed on the inner wall of the filter plate.

[0015] Furthermore, the lifting component includes a cylinder and a hydraulic cylinder fixed inside the cylinder. The output end of the hydraulic cylinder is slidably connected to the hollow tube, and a strong magnet is fixedly installed at the output end of the hydraulic cylinder. The strong magnet attracts the permanent magnet sheet.

[0016] Furthermore, the cleaning component includes a fixing ring and scraping frame plates fixed on both sides of the fixing ring. Several base plates are fixedly installed inside the scraping frame plates. A third spring is fixedly installed on one side of the base plate. A scraper is slidably connected inside the scraping frame plates. The third spring is fixedly connected to the scraper. The filter plate is in contact with the scraper.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When hydrogen sulfide gas is produced in the compost at the bottom of the fermenter, the driving agitator causes the two pushers to open. At this time, the pushers can open the isolation membrane, causing the isolation membrane to extend into a circular plate shape towards the inner wall of the fermenter until it contacts the inner wall, dividing the fermenter into three layers: upper, middle, and lower. The bottom layer directly isolates the already decomposed compost, the middle layer acts as a "transition buffer zone" to intercept and separate putrefactive microorganisms or harmful substances that diffuse from the bottom layer, and the upper layer can retain uncontaminated compost to the greatest extent. The multi-layer structure can reduce the risk of putrefactive bacteria breaking through a single barrier, allowing more time for subsequent processing. Furthermore, after dividing the fermenter into multiple layers, the driving agitator can turn over the compost in each layer, avoiding local compost compaction caused by isolation and reducing the risk of diffusion.

[0019] When the compost at the bottom of the fermentation tank begins to decompose and leachate is produced, the filter plate is raised by the lifting mechanism. This pushes the compost pile upwards a certain distance, separating the solids and liquids through the filter plate. At this point, a gap exists between the compost pile and the bottom of the tank. Due to gravity, the black leachate can flow into the gap between the filter plate and the bottom of the tank. The agitator then drives the cleaning mechanism to rotate, which cleans the leachate in the gap through the discharge port and removes it from the bottom of the fermentation tank. This improves the cleaning effect of the leachate and prevents the problem of leachate retention. Attached Figure Description

[0030] 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.

[0031] To address the technical problems of insufficient separation structure leading to contamination of normal fermentation areas by putrefactive materials and poor leachate drainage, such as... Figures 1-9 As shown, the following preferred technical solutions are provided:

[0032] like Figures 1-2As shown, a high-efficiency composting fermentation device for treating agricultural and livestock solid waste includes a fermentation tank 1. Three gas sensors 2 at different heights are installed through the surface of the fermentation tank 1. The gas sensors 2 can monitor the gas in the compost inside the fermentation tank 1. Since the essence of composting is abnormal microbial metabolism under anaerobic conditions, the bottom layer is prone to forming local anaerobic zones due to material compaction and poor air permeability. Anaerobic bacteria will decompose organic matter to produce hydrogen sulfide. At this time, the gas sensors 2 can monitor in real time whether hydrogen sulfide gas is produced inside the compost. The gas sensors 2 can directly, quickly and specifically capture hydrogen sulfide gas, making them the optimal single choice for detecting the composting at the bottom layer. The fermentation tank 1 is equipped with a driving agitator 3, which can turn and agitate the compost inside the fermentation tank 1, allowing the compost to fully contact oxygen. Two pushers 4 at different heights are installed on the surface of the driving agitator 3, and both pushers 4 are slidably connected to the fermentation tank 1. An isolation membrane 5 is installed on one side of the pushers 4.

[0033] The separator 5 is made of a material with high ductility and high wear resistance, such as TPU separator 5. TPU (thermoplastic polyurethane elastomer) has good elasticity and wear resistance, with a high elongation at break, reaching 300%-1000%, allowing it to be stretched and bent significantly without breaking. It also has excellent surface wear resistance, making it suitable for applications requiring dynamic deformation and wear resistance. It resists friction from hard particles in composting to a certain extent. The driving agitator 3 causes the two pushing components 4 to open, thus opening the separator 5 and causing it to form a circular plate shape towards the fermentation process. The inner wall of tank 1 extends until it contacts the inner wall of fermentation tank 1, dividing fermentation tank 1 into three layers: upper, middle, and lower. The bottom layer directly isolates the already decomposed compost, the middle layer serves as a "transition buffer zone" to intercept decomposed microorganisms or harmful substances that spread from the bottom layer, and the upper layer can retain uncontaminated compost to the greatest extent. The multi-layer structure reduces the risk of decomposed bacteria breaking through a single-layer barrier, allowing more time for subsequent processing. Furthermore, after dividing fermentation tank 1 into multiple layers, the driving agitator 3 can turn over the compost in each layer, avoiding local compost compaction caused by isolation and reducing the risk of spread.

[0034] The fermenter 1 is equipped with two sealing elements 6 corresponding to the isolation membrane 5. These sealing elements 6 improve the sealing reliability between the isolation membrane 5 and the inner wall of the fermenter 1. One end of each sealing element 6 is connected through to one side of the fermenter 1. A hollow tube 7 is fixedly installed at one end of the driving agitator 3. The hollow tube 7 is rotatably connected to the bottom of the fermenter 1. A filter plate 8 is fitted onto the surface of the hollow tube 7. The filter plate 8 supports and filters the compost, better separating the compost from the leachate. The filter plate 8 is in contact with the bottom of the fermenter 1. A lifting element 9 is fixedly installed at one end of the fermenter 1. The output end of the lifting element 9 is slidably connected to the hollow tube 7, and the output end of the lifting element 9 attracts the filter plate 8. When there is rotten material at the bottom of the fermenter 1, the rotten material... The filter plate 8 is in contact with the bottom of the tank, with no gap between them. Black leachate leaves dead corners. The lifting component 9 lifts the filter plate 8, which pushes the putrefied material upwards a certain distance. At this time, there is a gap between the putrefied material and the bottom of the tank. Due to gravity, the black leachate can flow into the gap between the filter plate 8 and the bottom of the tank. The hollow tube 7 is fixedly installed with a cleaning component 10, and the cleaning component 10 is in contact with the bottom of the fermentation tank 1 and the filter plate 8. One end of the fermentation tank 1 has a discharge hole 20. At this time, the cleaning component 10 is rotated by the driving agitator 3. The cleaning component 10 cleans the leachate in the gap through the discharge hole 20 and removes it from the bottom of the fermentation tank 1. This can improve the cleaning effect of the leachate and prevent the problem of leachate retention.

[0035] Three gas sensors 2 can monitor the gas content of the compost inside the fermentation tank 1. Due to the compaction and poor permeability of the material at the bottom of the fermentation tank 1, local anaerobic zones are easily formed. Anaerobic bacteria decompose organic matter and produce hydrogen sulfide. At this time, the gas sensors 2 can monitor in real time whether hydrogen sulfide gas is produced inside the compost. When hydrogen sulfide gas is produced in the compost at the bottom of the fermentation tank 1, the gas sensors 2 transmit the data to the controller (the controller is existing technology and is not shown in the figure). The controller drives the stirring component 3, which in turn causes the two pushing components 4 to open. The pushing components 4 can open the isolation membrane 5 and make the isolation membrane 5 extend into a circular plate shape towards the inner wall of the fermentation tank 1 until it contacts the inner wall of the fermentation tank 1, dividing the fermentation tank 1 into three layers: upper, middle and lower. The bottom layer directly isolates the already decomposed compost. The middle layer acts as a "transition buffer zone" to intercept the decaying microorganisms or harmful substances that diffuse from the bottom layer and separate the harmful substances. The upper layer can retain the uncontaminated compost to the greatest extent. The multi-layer structure can reduce the risk of decaying bacteria breaking through a single layer barrier and buy more time for subsequent processing.

[0036] Furthermore, after dividing the fermentation tank 1 into multiple layers, the driving agitator 3 can turn and toss the compost in each layer, avoiding local compost compaction caused by isolation and reducing the risk of spread. When the compost at the bottom of the fermentation tank 1 shows signs of decay and produces leachate, the lifting device 9 lifts the filter plate 8, which can push the decayed material upwards a certain distance. At this time, there is a gap between the decayed material and the bottom of the tank, and the black leachate can flow into the gap between the filter plate 8 and the bottom of the tank due to gravity. At this time, the driving agitator 3 drives the cleaning device 10 to rotate, and the cleaning device 10 cleans the leachate in the gap through the discharge hole 20 and removes it from the bottom of the fermentation tank 1, which can improve the cleaning effect of the leachate and prevent the problem of leachate retention.

[0037] like Figures 3-7 As shown, the surface of the fermentation tank 1 is equipped with three viewing doors 11 at different heights. The three viewing doors 11 at different heights correspond to the upper, middle and lower layers separated inside the fermentation tank 1. By opening the viewing doors 11, the compost in different layers can be aerated as needed. For example, through the bottom viewing door 11, high-pressure oxygen can be introduced into the compost, with a flow rate 2-3 times that of normal fermentation, for 1-2 hours, to forcibly break the anaerobic environment. At the same time, the compost is stirred to break up the compacted putrefied material at the bottom, allowing oxygen to fully penetrate and restoring the putrefied material at the bottom to a normal fermentation state as much as possible. The fermentation tank 1 is equipped with a discharge door 12 near the bottom, four horizontal plates 13 are installed inside the fermentation tank 1, and a support plate 14 is installed at the bottom of the fermentation tank 1.

[0038] The driving agitator 3 includes a support frame 31 and a motor 32 fixed inside the support frame 31. The support frame 31 is fixedly connected to the fermentation tank 1. A shaft 33 is fixedly installed at the output end of the motor 32. The shaft 33 is rotatably connected to the fermentation tank 1 and the support plate 14. Two sets of threaded grooves 34 are correspondingly provided on the surface of the shaft 33. The pusher 4 can be driven to open the isolation membrane 5 through the corresponding threaded grooves 34. Three stirring rods 35 are respectively installed on the surface of the shaft 33. The motor 32 can drive the shaft 33 to rotate. The rotation of the shaft 33 can drive the three stirring rods 35 to rotate. The three stirring rods 35 can turn over the compost in the upper, middle and lower layers.

[0039] The pushing component 4 includes a first support base 41 and a second support base 42 disposed on the surface of the shaft 33. Both ends of the isolation membrane 5 are fixedly connected to the first support base 41 and the second support base 42. The first support base 41 is in contact with the surface of the shaft 33. Several first connecting rods 43 are rotatably connected to the surface of the first support base 41. A second connecting rod 44 is hinged to one end of each first connecting rod 43, and one end of the second connecting rod 44 is rotatably connected to the second support base 42. A protective cylinder 45 is installed on one side of both the first support base 41 and the second support base 42. The protective cylinder 45 provides protection. When the first support base 41 and the second support base 42 move relative to each other, the protective cylinder 45 can be moved. The protective cylinder 45 can protect the threaded groove 34, preventing compost inside the fermenter 1 from adhering to the surface of the threaded groove 34. The protective cylinder 45 is slidably connected to the shaft 33 and the cross plate 13. Limiting rods 46 are fixedly installed on both sides of the protective cylinder 45. Both limiting rods 46 are slidably connected to the cross plate 13. When the first support 41 and the second support 42 move relative to each other, the first connecting rod 43 and the second connecting rod 44 will also move relative to each other. At this time, the two rotating first connecting rods 43 and the second connecting rod 44 can push the isolation membrane 5 to extend until it contacts the sealing element 6 on the fermenter 1. Therefore, the fermenter 1 can be divided into upper, middle and lower layers by the two sets of isolation membranes 5.

[0040] A first housing 411 is fixedly installed on one side of the first support base 41. The first housing 411 is slidably connected to the shaft 33. A first electromagnet 412 is installed inside the first housing 411. A first threaded plate 413 is slidably connected inside the first housing 411. The first threaded plate 413 matches the threaded groove 34. A first magnet block 414 is fixedly installed on one side of the first threaded plate 413. Several first springs 415 are fixedly installed on one side of the first threaded plate 413. In the initial state, the elastic force of the first springs 415 causes the first threaded plate 413 to retract into the first housing 411. The first springs 415 can play a connecting role and are fixedly connected to the first housing 411. Two hooks 416 are fixedly installed on one side of the first housing 411.

[0041] When the first electromagnet 412 is energized, it generates a strong repulsive force on the first magnet block 414, which pushes the first threaded plate 413 to move until it contacts the threaded groove 34 on the surface of the shaft 33. At this time, since the limiting rod 46 is slidably connected to the cross plate 13, it can limit the first support seat 41. Therefore, when the shaft 33 rotates, it can drive the first housing 411 to move through the engagement of the threaded groove 34 and the first threaded plate 413, allowing the first connecting rod 43 and the second connecting rod 44 to rotate relative to each other. When the first electromagnet 412 is de-energized, the elastic force of the first spring 415 causes the first threaded plate 413 to retract into the interior of the first housing 411. At this time, the first threaded plate 413 no longer contacts the threaded groove 34. Therefore, when the shaft 33 rotates, it no longer drives the first support seat 41 to move. This allows for conversion according to needs and improves applicability.

[0042] A second housing 421 is fixedly installed on one side of the second support base 42. The second housing 421 is slidably connected to the shaft 33. A second electromagnet 422 is installed inside the second housing 421. A second threaded plate 423 is slidably connected inside the second housing 421. The second threaded plate 423 matches the threaded groove 34. A second magnet block 424 is fixedly installed on one side of the second threaded plate 423. Several second springs 425 are fixedly installed on one side of the second threaded plate 423. In the initial state, the elastic force of the second springs 425 causes the second threaded plate 423 to retract to the second... Inside the housing 421, a second spring 425 serves as a connector, and the second spring 425 is fixedly connected to the second housing 421. Two vertical plates 426 are installed inside the second housing 421. L-shaped rods 427 are fixedly installed on both sides of the second threaded plate 423, and the L-shaped rods 427 are slidably connected to the second housing 421. A support rod 428 is fixedly installed at one end of the L-shaped rod 427, and the support rods 428 are slidably connected to the two vertical plates 426. Two rectangular holes 429 corresponding to hooks 416 are opened through one side of the second housing 421.

[0043] When the second electromagnet 422 is energized, it generates a large repulsive force on the second magnet block 424, which pushes the second threaded plate 423 to move until the second threaded plate 423 contacts the threaded groove 34 on the surface of the shaft 33. At the same time, the L-shaped rod 427 can push the support rod 428 to move. Since the limiting rod 46 is slidably connected to the cross plate 13, it can limit the second support seat 42. Therefore, when the shaft 33 rotates, it can drive the second housing 421 to move through the cooperation of the threaded groove 34 and the second threaded plate 423.

[0044] The two opposing threaded grooves 34 can simultaneously drive the second support 42 and the first support 41 to move relative to each other, allowing the first connecting rod 43 and the second connecting rod 44 to rotate relative to each other until the first housing 411 and the second housing 421 come into contact. Then, the two hooks 416 are inserted into the second housing 421 through the rectangular hole 429. Subsequently, the second electromagnet 422 and the first electromagnet 412 are no longer energized. At this time, the elastic force of the second spring 425 and the first spring 415 causes the first threaded plate 413 and the second threaded plate 423 to retract into the first housing 411 and the second housing 421. The support rod 428 then contacts the two hooks 416, forming a snap-fit ​​that fixes the first housing 411 and the second housing 421 together. At this point, the first threaded plate 413 and the second threaded plate 423 no longer contact the threaded grooves 34. Therefore, when the shaft 33 rotates, it no longer drives the first support 41 and the second support 42 to move. This allows for conversion as needed, improving applicability. Conversely, the operation can separate the first support 41 and the second support 42.

[0045] like Figure 9 As shown, permanent magnet plates 81 are installed on the inner wall of the filter plate 8. These permanent magnet plates 81 act as a connection, enabling the filter plate 8 to move. The lifting component 9 includes a cylinder 91 and a hydraulic cylinder 92 fixed inside the cylinder 91. The output end of the hydraulic cylinder 92 is slidably connected to the hollow tube 7. A strong magnet 93 is fixedly installed at the output end of the hydraulic cylinder 92, and the strong magnet 93 attracts the permanent magnet plates 81. The hydraulic cylinder 92 can push the strong magnet 93 upwards inside the hollow tube 7. The magnetic attraction between the strong magnet 93 and the permanent magnet plates 81 causes the filter plate 8 to move upwards synchronously. The filter plate 8 lifts the compost, and the filter plate 8 and the hollow tube 7 slide only by magnetic attraction, eliminating the need for sealed bearings or rigid connectors, thus eliminating leakage channels from the structure. The attraction force of the strong magnet 93 and the permanent magnet 81 is greater than the sum of the total weight of the filter plate 8, the compost, and the sliding friction. Secondly, when rotating, the sliding contact part between the hollow tube 7 and the filter plate 8 will generate circumferential friction, but this friction is much smaller than the magnetic driving force and will not hinder the lifting. If the rotation and lifting actions are carried out simultaneously, the relative movement between the magnets can reduce the jamming caused by static attraction and may even improve the smoothness of the lifting.

[0046] The cleaning component 10 includes a fixing ring 101 and scraping frame plates 102 fixed on both sides of the fixing ring 101. Several base plates 103 are fixedly installed inside the scraping frame plates 102. A third spring 104 is fixedly installed on one side of the base plate 103. A scraper 105 is slidably connected inside the scraping frame plates 102. The third spring 104 is fixedly connected to the scraper 105. The filter plate 8 is in contact with the scraper 105. When the hollow tube 7 rotates, it can drive the fixing ring 101 and the scraping frame plates 102 to rotate. The scraping frame plates 102 can clean the leachate in the gap through the discharge hole 20 to the bottom of the fermenter 1, which can improve the cleaning effect of the leachate and prevent the problem of leachate retention. When the filter plate 8 moves upward, the spring force of the third spring 104 causes the scraper 105 to move upward and contact the filter plate 8. Therefore, one side of the filter plate 8 can also be cleaned, improving the scraping effect.

[0047] To address the technical problem of poor sealing due to composting during the separation process, such as... Figure 8 As shown, the following preferred technical solutions are provided:

[0048] The sealing element 6 includes a concave circular plate 61 and a circular air bladder 62 installed inside the concave circular plate 61. A connecting pipe 63 is connected to one side of the circular air bladder 62, and the connecting pipe 63 is connected to both the concave circular plate 61 and the fermenter 1. One end of the connecting pipe 63 is connected to an air pump 64, and a solenoid valve 65 is installed on the surface of the connecting pipe 63. After the isolation membrane 5 extends, it contacts the groove in the concave circular plate 61. At this time, the circular air bladder 62 in the concave circular plate 61 is fully filled with air, which can prevent compost from entering the groove. When the isolation membrane 5 contacts the circular air bladder 62, the circular air bladder 62 is pushed by the continuous squeezing force. At this time, the solenoid valve 65 is opened, which can release some of the gas inside the circular air bladder 62, so that the edge of the isolation membrane 5 is completely filled with the circular air bladder 62, changing from rigid full filling to flexible fit. It adapts to the shape of the edge of the isolation membrane 5 and deforms accordingly. The residual pressure ensures that the circular air bladder 62 and the isolation membrane 5 are in close contact, forming a multi-layer seal, which is better than the initial full filling state.

[0049] After the isolation membrane 5 separates from the circular air bladder 62, the solenoid valve 65 is closed, and the circular air bladder 62 is re-inflated to full pressure by the air pump 64. During the expansion process, any small amount of compost residue that may be adhering to the inner wall of the concave circular plate 61 or the surface of the circular air bladder 62 will be completely pushed out of the concave circular plate 61 and fall into the composting area below. Therefore, the initial full-inflation state is restored, which can prepare for the next contact of the isolation membrane 5. Thus, the sealing and cleaning functions are deeply integrated, which improves the sealing reliability between the isolation membrane 5 and the inner wall of the fermenter 1, and avoids secondary pollution of residual compost through active cleaning.
