The fermentation bag has four pull rings. One side of the PVC mesh fabric fermentation bag has a feed hole, inside which a PVC feed pipe is fixedly installed. The opening of the PVC feed pipe extends to the bottom inner wall of the PVC mesh fabric fermentation bag. The other side of the PVC mesh fabric fermentation bag has a discharge hole, inside which a PVC discharge pipe is fixedly installed. The opening of the PVC discharge pipe extends to the bottom inner wall of the PVC mesh fabric fermentation bag. Four tension limiting components are symmetrically arranged on both sides of the PVC mesh fabric fermentation bag to prevent displacement during use. The pull rings are used in conjunction with the tension limiting components.
[0006] As a preferred technical solution of this utility model, the tensioning and limiting component includes a fixing column, which is disposed on one side of the PVC mesh fermentation bag. A U-shaped mounting bracket is fixedly installed on the top of the fixing column. Circular holes are opened on both sides of the U-shaped mounting bracket. A winding roller is rotatably installed inside the circular holes. Two discs are symmetrically fixedly installed on the outer side of the winding roller. Several levers are fixedly installed on the outer side of the discs. A handwheel is fixedly installed at one end of the winding roller.
[0007] As a preferred technical solution of this utility model, the tensioning and limiting component further includes two sliding grooves. The two sliding grooves are symmetrically opened on both sides of the inside of the U-shaped mounting bracket. A rectangular groove is opened on the bottom surface of the inside of the sliding groove. An arc-shaped guide groove is opened on one side of the inside of the rectangular groove. A slider is movably installed inside the sliding groove. A spring is fixedly installed on the top of the slider. The other end of the spring is fixedly installed on the top surface of the inside of the sliding groove. A movable groove is opened on the opposite side of the two sliders.

The steel wire rope on the outside of the winding roller is connected to the hook and the pull ring on the top of the chamber. The steel wire rope can be manually wound clockwise by turning the handwheel. During winding, the lever pushes the limiting baffle to rotate, and the guide rod moves along the arc-shaped guide groove to release the obstruction to the winding roller. After releasing the lever, the limiting baffle returns to its original position due to gravity, preventing the winding roller from rotating counterclockwise in a vertical state. This fixes the tension of the steel wire rope and prevents the fermentation chamber from shifting or deforming due to internal air pressure or external force, ensuring the stability of the device structure.

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0023] Figures 1-7 are the preferred embodiments of this utility model. The utility model will be further described below with reference to Figures 1-7.
[0024] A fermentation device for livestock manure includes a PVC mesh fermentation bag 1. Several hanging buckles 2 are symmetrically fixedly installed on the outer side of the PVC mesh fermentation bag 1. A hanging rope 201 is movably installed inside each hanging buckle 2. A first mounting hole 3 is opened at the top of the PVC mesh fermentation bag 1, and a pressure reducing valve 4 is fixedly installed inside the first mounting hole 3. A second mounting hole 5 is opened at the top of the PVC mesh fermentation bag 1, and an exhaust pipe 6 is fixedly installed inside the second mounting hole 5. A gate valve 7 is fixedly installed at the other end of the exhaust pipe 6. Four pull rings 8 are symmetrically fixedly installed at the top of the PVC mesh fermentation bag 1. A feed hole is provided on one side of the PVC mesh fermentation bag 1. A PVC feed pipe 9 is fixedly installed inside the feed hole. The opening of the PVC feed pipe 9 extends to the bottom inner wall of the PVC mesh fermentation bag 1. A discharge hole is provided on the other side of the PVC mesh fermentation bag 1. A PVC discharge pipe 10 is fixedly installed inside the discharge hole. The opening of the PVC discharge pipe 10 extends to the bottom inner wall of the PVC mesh fermentation bag 1. Four tension limiting components are symmetrically arranged on both sides of the PVC mesh fermentation bag 1 to prevent displacement of the PVC mesh fermentation bag 1 during use. The pull ring 8 is used in conjunction with the tension limiting components.
[0025] In this implementation scheme, a PVC mesh fermentation tank 1 is constructed using PVC mesh fabric, which is UV resistant, acid and alkali corrosion resistant, and has high airtightness, allowing for stable use in an anaerobic fermentation environment for manure. It features an inlet and outlet port on the side, and a first mounting hole 3 and a second mounting hole 5 on the top. A sealed structure is formed through hot-melt welding. By controlling the liquid level at the top, an anaerobic environment is created, allowing the manure to completely ferment into biogas slurry, eliminating harmful substances such as E. coli and parasite eggs. The cost is only about 10% of that of a traditional concrete manure tank. The fermented biogas slurry can be used as organic fertilizer for resource utilization. Hangers 2 are symmetrically fixed to the PVC mesh tank. The outer side of the PVC mesh fermentation bag 1 provides a connection point for the lifting rope 201, facilitating the transportation and installation of the PVC mesh fermentation bag 1. The lifting rope 201 is movably installed inside the lifting buckle 2 and is connected to external lifting equipment during transportation and installation. The PVC mesh fermentation bag 1 is smoothly lifted and placed in the pre-set groove by the pulling force. The first mounting hole 3 is opened at the top of the PVC mesh fermentation bag 1 for fixing and installing the pressure reducing valve 4. The pressure reducing valve 4 is installed in the first mounting hole 3 at the top. When the biogas pressure inside the bag exceeds the set value, the pressure reducing valve 4 can be opened to release gas, preventing the bag from rupturing due to excessive gas pressure, ensuring the safety of the fermentation process, and avoiding abnormal gas pressure. To prevent explosions and other hazards, the second mounting hole 5 is used to fix the exhaust pipe 6. The other end of the exhaust pipe 6 is connected to the gate valve 7 to discharge the biogas produced during fermentation to an open area. The gate valve 7 controls the exhaust volume to prevent biogas accumulation from affecting fermentation efficiency or causing safety hazards. The gate valve 7 is manually operated to control biogas emission and can adjust the exhaust frequency according to the fermentation process to ensure that the gas pressure inside the bladder is stable within the range required for anaerobic fermentation. The pull ring 8 is connected to the hook 12 of the tensioning and limiting component, serving as the point of application of the tension of the wire rope 11. The tensioning and limiting component restricts the position of the bladder to prevent it from shifting. The feed hole is opened in the PVC mesh fabric fermentation area. At the bottom of the bladder 1, a PVC feed pipe 9 is fixedly installed to provide a channel for the input of manure. The PVC feed pipe 9 facilitates the uniform input of livestock and poultry manure from the bottom into the PVC mesh fermentation bladder 1. The discharge hole is used to fixally install a PVC discharge pipe 10 to provide a channel for the discharge of biogas slurry after fermentation. The PVC discharge pipe 10 can smoothly discharge the biogas slurry after fermentation. The tensioning and limiting component, through the cooperation of components such as the fixing column 13, U-shaped mounting frame 14, winding roller 15, and steel wire rope 11, allows for manual adjustment and locking of the tension to prevent the PVC mesh fermentation bladder 1 from shifting due to internal pressure or external factors during use, thus ensuring the stable operation of the device.
[0026] Specifically, the tensioning and limiting assembly includes a fixing post 13, which is set on one side of the PVC mesh fermentation bag 1. A U-shaped mounting bracket 14 is fixedly installed on the top of the fixing post 13. Circular holes are opened on both sides of the U-shaped mounting bracket 14. A winding roller 15 is rotatably installed inside the circular holes. Two discs 16 are symmetrically fixedly installed on the outer side of the winding roller 15. Several levers 17 are fixedly installed on the outer side of the discs 16. A handwheel 18 is fixedly installed at one end of the winding roller 15.
[0027] In this embodiment, a fixed column 13 is embedded on one side of the PVC mesh fermentation bag 1 to provide stable support for the tensioning and limiting component, ensuring the stability of the entire component when pulling the PVC mesh fermentation bag 1. The U-shaped mounting bracket 14 provides mounting support for the winding roller 15, ensuring that the winding roller 15 can rotate stably, and at the same time provides a mounting frame for components such as the slide chute 20. The winding roller 15 is driven to rotate by the handwheel 18 to wind up or release the wire rope 11. The tension of the wire rope 11 pulls the top pull ring 8 of the PVC mesh fermentation bag 1, thereby achieving the traction and limiting of the position of the PVC mesh fermentation bag 1. To prevent displacement, the disc 16 is symmetrically installed on the outside of the take-up roller 15, providing mounting support for the lever 17. The lever 17 rotates with the take-up roller 15, pushing the limit baffle 19 to flip when the wire rope 11 is being wound, thus releasing the obstruction to the take-up roller 15 and ensuring smooth winding. After winding is completed, the limit baffle 19 resets to prevent the take-up roller 15 from reversing, maintaining the tension of the wire rope 11 and limiting the position of the PVC mesh fermentation bag 1. The handwheel 18 provides a point of leverage for manual operation of the take-up roller 15. By rotating the handwheel 18, the rotation of the take-up roller 15 is controlled, thereby adjusting the tension of the wire rope 11.
[0028] Specifically, the tensioning and limiting assembly also includes two slide grooves 20, which are symmetrically opened on both sides of the inside of the U-shaped mounting bracket 14. A rectangular groove 23 is opened on the bottom surface of the inside of the slide groove 20, and an arc-shaped guide groove 24 is opened on one side of the inside of the rectangular groove 23. A slider 21 is movably installed inside the slide groove 20, and a spring 22 is fixedly installed on the top of the slider 21. The other end of the spring 22 is fixedly installed on the top surface of the inside of the slide groove 20. Movable grooves are opened on the opposite side of the two sliders 21.
[0029] In this embodiment, a chute 20 is provided to provide a track for the slider 21 to move up and down. Simultaneously, the internal rectangular groove 23 and arc-shaped guide groove 24 provide a path for the guide rod 26 to move, ensuring the accuracy of the flipping and resetting actions of the limiting baffle 19. This guarantees the limiting effect of the tensioning limiting component on the PVC mesh fermentation bag 1. The rectangular groove 23 provides space for the guide rod 26 to move upwards with the limiting baffle 19 during unlocking. The arc-shaped guide groove 24 cooperates with the guide rod 26, guiding the guide rod 26 along the arc-shaped trajectory when the lever 17 pushes the limiting baffle 19 to flip, allowing the limiting baffle 19 to flip smoothly and release the obstruction to the winding roller 15, facilitating the winding of the wire rope 11. After winding, the guide rod 26 resets, restoring the limiting baffle 19 to a vertical state, preventing the winding roller 15 from flipping, and maintaining the control over the PVC mesh fermentation bag 1. The traction limit is achieved by an arc-shaped guide groove 24, which allows the limit baffle 19 to rotate clockwise in only one direction. The slider 21 is movably installed inside the slide groove 20, with its top connected to the spring 22. A movable groove is provided on the side for installing the movable rod 25 of the limit baffle 19. When the wire rope 11 needs to be unlocked and released, the limit baffle 19 is manually pulled up, and the slider 21 slides upward and compresses the spring 22, providing support for the movement of the limit baffle 19. When the wire rope 11 is unlocked and released, the spring 22 releases its elastic force, pushing the limit baffle 19 back to its initial position, ensuring that the tensioning limit assembly has a stable traction limit force on the PVC mesh fermentation bag 1 and preventing the bag's position from shifting. The movable groove is used to movably mount the movable rod 25 of the limit baffle 19, linking the slider 21 with the limit baffle 19. During the upward movement and downward reset of the limit baffle 19, the slider 21 can be driven to move up and down within the slide groove 20 by the movable rod 25.
[0030] Specifically, the tensioning and limiting assembly also includes a limiting baffle 19, which is movably installed inside the U-shaped mounting bracket 14. Movable rods 25 are fixedly installed on both sides of the limiting baffle 19, and the movable rods 25 are movably sleeved inside the movable groove. Guide rods 26 are fixedly installed on both sides of the limiting baffle 19, and the guide rods 26 are movably sleeved inside the rectangular groove 23. The guide rods 26 are used in conjunction with the arc-shaped guide groove 24.
[0031] In this embodiment, by setting a limiting baffle 19, which is connected to the slider 21 via the movable rod 25 and cooperates with the guide rod 26 and the arc-shaped guide groove 24, the one-way limiting of the take-up roller 15 is achieved. When the wire rope 11 is wound up, the lever 17 pushes the limiting baffle 19 to flip, releasing the obstruction to the take-up roller 15. After winding is completed, the limiting baffle 19 returns to the vertical state due to gravity, preventing the take-up roller 15 from rotating counterclockwise, locking the tension of the wire rope 11, and preventing the PVC mesh fermentation bag 1 from displacing due to internal pressure or external factors. When the movable rod 25 is unlocked, the limiting baffle 19 is manually pulled up, and the movable rod 25 drives the slider 21 to move up, ensuring that the movement of the limiting baffle 19 is smooth and avoiding jamming. When the guide rod 26 is wound up, it moves along the arc-shaped guide groove 24 to guide the flipping angle of the limiting baffle 19. When unlocking, it moves up along the rectangular groove 23.
[0032] Specifically, a wire rope 11 is fixedly installed on the outer side of the take-up roller 15, and a hook 12 is fixedly installed on the other end of the wire rope 11. The hook 12 is used in conjunction with the pull ring 8.
[0033] In this embodiment, a steel wire rope 11 is fixed to the outside of the winding roller 15. The steel wire rope 11 has high strength and converts the rotational force of the winding roller 15 into a traction force on the top of the PVC mesh fermentation bag 1. This counteracts the expansion or displacement of the bag caused by the buoyancy of biogas and the pressure of manure, thus maintaining the stability of the PVC mesh fermentation bag 1. The hook 12 is fixed to the other end of the steel wire rope 11 and is detachably connected to the top pull ring 8 of the PVC mesh fermentation bag 1. This ensures that the tension of the steel wire rope 11 is accurately transmitted to the top of the bag, while also facilitating installation and maintenance. Together with the tensioning and limiting component, it achieves positional constraint on the PVC mesh fermentation bag 1.
[0034] Specifically, the PVC mesh fermentation bag 1 is made of PVC mesh fabric, and the inside of the slide groove 20 has limit grooves on both sides. Limit blocks are fixedly installed on both sides of the slider 21, and the limit blocks are movably sleeved inside the limit grooves.
[0035] In this embodiment, by setting a limiting groove, which is opened on both sides inside the slide groove 20, a sliding fit structure is formed with the limiting blocks on both sides of the slider 21, the movement trajectory of the slider 21 is precisely restricted, so that it can only slide up and down along the limiting groove, avoiding lateral displacement or shaking of the slider 21 in the slide groove 20. The limiting blocks are fixedly installed on both sides of the slider 21 and movably sleeved in the limiting groove. Through the cooperation with the limiting groove, the movement direction of the slider 21 is constrained, ensuring the verticality and stability of the slider 21 when it moves up and down in the slide groove 20.
[0036] In summary, when using this invention, a placement groove of similar size to the PVC mesh fermentation bag 1 is excavated on a flat surface using mechanical equipment. A layer of cotton quilt is laid inside the placement groove to provide insulation and cushioning, reducing the impact of external ambient temperature on the fermentation temperature of the manure inside the PVC mesh fermentation bag 1, and preventing the PVC mesh fermentation bag 1 from being damaged by direct contact with hard objects on the ground. The PVC mesh fermentation bag 1 is connected to a lifting device via a hook 2 and a rope 201, allowing it to be smoothly lifted and placed into the placement groove. The PVC mesh fermentation bag 1 is made of PVC mesh fabric, which has excellent UV resistance and can withstand outdoor sunlight. The fermentation chamber 1 is designed to effectively resist acid and alkali corrosion from manure and has good airtightness to prevent biogas leakage. It features an inlet and outlet port at the bottom, with PVC inlet pipe 9 and PVC outlet pipe 10 installed for manure input and biogas discharge respectively. A first mounting hole 3 and a second mounting hole 5 are located at the top, with a pressure reducing valve 4 and an exhaust pipe 6 installed respectively. A gate valve 7 is installed at the other end of the exhaust pipe 6. By controlling the liquid level, a closed anaerobic environment is formed at the top of the PVC mesh fermentation chamber 1, allowing manure to ferment under anaerobic conditions. The generated biogas can be discharged through the exhaust pipe 6, which is then led to an open area. The pressure reducing valve 4 automatically regulates the internal pressure to prevent excessive pressure.
[0037] During fermentation, to prevent the PVC mesh fermentation bag 1 from shifting due to internal pressure or external factors, the fixing posts 13 should first be buried around the placement groove, and the positions of the fixing posts 13 should correspond to the four pull rings 8 symmetrically fixed at the top of the PVC mesh fermentation bag 1. Then, hook 12 at one end of the tensioning and limiting component's wire rope 11 onto the pull rings 8 at the top of the PVC mesh fermentation bag 1, connecting the wire rope 11 to the pull rings 8. Manually turn the handwheel 18 clockwise to rotate the take-up roller 15. The take-up roller 15 drives the outer disc 16 and the lever 17 to rotate. The lever 17 pushes the limiting baffle 19 to rotate. At this time, the guide rods 26 on both sides of the limiting baffle 19 move along the arc-shaped guide groove 24 in the rectangular groove 23. The limiting baffle 19 flips over to release the obstruction to the take-up roller 15. 15. Wind the steel wire rope 11 clockwise to pull the top of the PVC mesh fermentation bag 1. When the lever 17 disengages from the limiting baffle 19, the limiting baffle 19 returns to a vertical state due to gravity. When the hand leaves the handwheel 18, the limiting baffle 19 prevents the winding roller 15 from rotating counterclockwise, fixing the tension of the steel wire rope 11 and limiting the PVC mesh fermentation bag 1. If it is necessary to release the steel wire rope 11, manually pull the limiting baffle 19 upward. The movable rods 25 on both sides move in the movable groove of the slider 21, driving the slider 21 to move upward in the slide groove 20 to compress the spring 22. The guide rod 26 moves upward along the rectangular groove 23. At this time, manually rotate the handwheel 18 counterclockwise to release the steel wire rope 11. After the release is completed, release the limiting baffle 19. The spring 22 resets and pushes the limiting baffle 19 back to its initial position.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
