Description

Technical Field

[0001] This invention belongs to the technical field of composting devices, and relates to a microbial fertilizer composting device and its usage method. Background Technology

[0002] Composting and fermentation of organic waste such as livestock and poultry manure, straw, and livestock wastewater residue is a key technology for achieving resource utilization and waste reduction. Its core principle is to convert organic matter into humus-rich organic fertilizer through the metabolic activities of aerobic microorganisms. Currently, industrially applied composting and fermentation devices mostly adopt a vertical tank structure, utilizing a stirring device in conjunction with an oxygen supply system for aerobic fermentation.

[0003] In vertical fermenters, compost material accumulates at the bottom due to its own weight, resulting in excessive compaction, reduced porosity, and significantly decreased aeration. This compaction makes it difficult for oxygen to penetrate to the bottom, limiting the activity of aerobic microorganisms and easily leading to the formation of localized anaerobic fermentation zones, which in turn cause the bottom material to rot and deteriorate. Once the bottom material has rotted, during agitation, the solid particles, anaerobic microorganisms, and harmful metabolites produced by the rot will be diffused to the middle and upper layers. This not only contaminates the material that was originally in a normal fermentation state but also causes a significant decline in the overall quality of the material in the fermenter.

[0004] To address the above problems, this invention proposes a microbial composting device and its usage method. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a microbial fertilizer composting device and its usage method.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a microbial fertilizer composting device, comprising... Tank body; A ventilation shaft is rotatably mounted inside the tank, and a sleeve is fitted on the outer side of the ventilation shaft; An isolation mechanism is disposed inside the tank and located outside the sleeve. The isolation mechanism includes a sliding ring, an electrically controlled rotating ring, and a partition cloth. The sliding ring is slidably disposed along the axial direction of the tank body, and the electrically controlled rotating ring is rotatably connected to the inner side of the sliding ring. The two ends of the spacer cloth are respectively connected to the sliding ring and the electrically controlled rotating ring; a detector is connected to the sliding ring. When an anaerobic putrefaction zone is formed at the bottom of the tank, the sliding ring drives the electrically controlled rotating ring and the partition cloth to slide to a preset height above the anaerobic putrefaction zone and remain fixed. The electrically controlled rotating ring rotates relative to the sliding ring and drives one end of the partition cloth to rotate, so that the partition cloth is twisted and deformed and wrapped tightly around the outside of the sleeve, thereby dividing the interior of the tank into an anaerobic putrefaction zone below the partition cloth and a normal fermentation zone above the partition cloth.

[0007] Furthermore, the tank body is internally fixedly connected to two fixed rods parallel to the ventilation shaft, and the sliding ring is slidably connected to the two fixed rods; The sliding ring is equipped with a brake-equipped electric roller, which abuts against the outer side of the fixed rod to drive the sliding ring to slide along the axial direction of the fixed rod and lock it at a preset height.

[0008] Furthermore, a baffle for cutting off its internal air passage is slidably connected to the outer side of the ventilation shaft; the ventilation shaft is rotatably connected to an annular rotating shell that communicates with the second sliding cavity where the baffle is located, and a rectangular rod is fixedly connected to the annular rotating shell, and the sleeve is slidably connected to the rectangular rod. The sleeve has a first sliding cavity, and a piston block is slidably connected in the first sliding cavity. A spring is connected between the piston block and the sleeve. The annular rotating shell is connected to the first sliding cavity via a metal flexible tube.

[0009] Furthermore, the spacer includes a fabric layer and a rubber layer fixedly connected to two opposite surfaces of the fabric layer; The outer side of the sleeve is provided with a friction layer or multiple friction protrusions.

[0010] Furthermore, a reciprocating spiral groove is provided on the inner side of the sleeve, and the sleeve is installed by cooperating with the outer side of the ventilation shaft through the reciprocating spiral groove; When the partition cloth is tightly wrapped around the outside of the sleeve corresponding to the preset height position and the baffle blocks the ventilation shaft, the ventilation shaft rotates relative to the sleeve during rotation, causing the sleeve to move up and down reciprocally along the axial direction of the ventilation shaft. When the brake with the electric roller is released, the sleeve drives the entire isolation mechanism and the materials in the normal fermentation zone to move up and down synchronously through the partition cloth.

[0011] Furthermore, a plurality of stirring rods connected to the outer side of the ventilation shaft are fixedly connected to the internal air passage, and each stirring rod is provided with a plurality of exhaust holes; The top and bottom of the tank are respectively fixedly connected to a first fixed shell and a second fixed shell. The ventilation shaft is provided with a first through hole communicating with the first fixed shell and a second through hole communicating with the second fixed shell.

[0012] Furthermore, a filter plate is fixedly connected to the bottom of the tank, and the bottom of the tank is provided with a discharge port equipped with an electrically controlled valve; The sliding ring has an arc-shaped cavity inside, and an arc-shaped filter plate is fixedly connected inside the arc-shaped cavity. A spring-loaded bellows telescopic tube is connected between the sliding ring and the filter plate, and the spring-loaded bellows telescopic tube communicates with the arc-shaped cavity.

[0013] Furthermore, the top of the tank is provided with a feeding port, and the bottom of the side wall of the tank is provided with a discharge door.

[0014] The method of using a microbial composting device according to the present invention includes the following steps: S1. Control the sliding ring to slide axially within the tank, and use a detector to detect the fermentation status of the material at different heights inside the tank; S2. When an anaerobic putrefaction zone is detected at the bottom of the tank, and the height boundary of the anaerobic putrefaction zone is determined according to the signal output by the detector, the sliding ring is controlled to slide to a preset height above the height boundary of the anaerobic putrefaction zone and locked. S3. Control the electrically controlled rotating ring to rotate relative to the sliding ring. The electrically controlled rotating ring drives one end of the partition cloth to rotate, causing the partition cloth to twist and deform, and its central diameter to shrink and finally wrap tightly around the outside of the sleeve. Thus, the taut partition cloth divides the inside of the tank into the lower anaerobic putrefaction zone and the upper normal fermentation zone.

[0015] S4. Introduce oxygen at a first pressure and a first flow rate into the normal fermentation zone, and introduce oxygen at a second pressure and a second flow rate into the anaerobic putrefaction zone, wherein the second pressure is greater than the first pressure and the second flow rate is greater than the first flow rate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: by moving the sliding ring up and down, the material in the tank is detected. When the anaerobic putrefaction zone is detected, the sliding ring is stopped at a preset height above the anaerobic putrefaction zone. Then, the sleeve is twisted and wrapped tightly with the partition cloth to separate the normal fermentation zone from the anaerobic putrefaction zone, thereby preventing the spread of putrefaction material and harmful microorganisms from the bottom layer to the upper layer of normal material, thus ensuring the fermentation quality.

[0017] When the sleeve is tightly wrapped with a partition cloth, the baffle separates the ventilation shaft, allowing oxygen to be injected into the normal fermentation zone at the first pressure and first flow rate, while oxygen is injected into the anaerobic putrefaction zone at the second pressure and second flow rate to salvage the putrefied material.

[0018] If the rescue is successful, remix the materials. If the rescue is unsuccessful, open the discharge door to remove the spoiled material from the tank, reducing waste and ensuring the normal fermentation of the remaining material, thus guaranteeing fermentation quality.

Detailed Implementation

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

[0022] Example 1: As Figures 1-12 As shown, the technical solution adopted by the present invention is as follows: A microbial fertilizer composting device (refer to...) Figure 1 and Figure 2 The microbial composting device provided in this embodiment includes a vertically arranged tank 1, a ventilation shaft 16, and an isolation mechanism.

[0023] like Figure 1 As shown, the top of the tank 1 is equipped with a sealable feeding port 2 for feeding composting materials such as livestock and poultry manure, straw, and livestock wastewater residue, as well as related additives, into the tank. A filter plate 4 is horizontally fixedly connected inside the tank 1. The liquid seeping out during the composting fermentation process flows through the filter plate 4 to the bottom of the tank 1. The bottom of the tank 1 is equipped with a discharge port 5 with an electrically controlled valve. By periodically controlling the electrically controlled valve to open the discharge port 5, the liquid at the bottom of the tank 1 can be drained in a timely manner.

[0024] Meanwhile, the bottom of the side wall of tank 1 is also equipped with an openable and closable discharge door 3, which is used to discharge materials after fermentation or to clean up irreparable rotten materials in case of failure to salvage.

[0025] like Figure 2 As shown, the ventilation shaft 16 is rotatably mounted inside the tank 1, with both ends penetrating the tank 1 axially. Figure 1 As shown, a motor 15 is fixedly installed on the outer side of the top of the tank 1. The motor shaft of the motor 15 is fixedly connected to the top of the ventilation shaft 16 to drive the ventilation shaft 16 to rotate inside the tank 1.

[0026] Multiple sleeves 26 are fitted onto the outer side of the ventilation shaft 16. For example... Figure 2 As shown, in this embodiment, four sleeves 26 are fitted on the outer side of the ventilation shaft 16.

[0027] like Figure 7 As shown, a reciprocating spiral groove 25 is provided on the ventilation shaft 16 at the position where it mates with the sleeve 26. A guide block is connected to the inner side of the sleeve 26 and is slidably disposed within the reciprocating spiral groove 25. When the ventilation shaft 16 rotates relative to the sleeve 26, the sleeve 26 moves up and down reciprocally along the ventilation shaft 16.

[0028] The length of a single reciprocating spiral groove 25 is less than the length of the sleeve 26, so that the reciprocating spiral groove 25 is always located inside the sleeve 26, avoiding direct contact between the reciprocating spiral groove 25 and the material.

[0029] like Figure 2 and Figure 4 As shown, the isolation mechanism is located inside the tank 1 and outside the sleeve 26. Specifically, two fixed rods 6 parallel to the venting shaft 16 are fixedly connected inside the tank 1, and the two fixed rods 6 are symmetrically distributed on both sides of the venting shaft 16.

[0030] The isolation mechanism includes an annular sliding ring 7, an electrically controlled rotating ring 10, and a cylindrical flexible partition 11. The sliding ring 7 is slidably connected to two fixed rods 6. Electric rollers 8 with brakes are installed on both sides inside the sliding ring 7. These electric rollers 8 are driven by a built-in first drive motor and equipped with independent electromagnetic brakes. When the electromagnetic brakes are energized, the sliding ring 7 is locked at its current height. The first drive motor is not self-locking; when the first drive motor is off, the electric rollers 8 with brakes can rotate freely and abut against the outer side of the corresponding fixed rod 6.

[0031] By controlling the forward and reverse rotation of the electric roller 8 with brake, the sliding ring 7 can be driven to slide up and down along the fixed rod 6 inside the tank 1. When the brake is locked, the sliding ring 7 can be stably locked at any preset height.

[0032] A detector 9 is installed on the sliding ring 7. The detector 9 detects the fermentation status of the material inside the tank 1.

[0033] In one embodiment, detector 9 is a multi-parameter composite fermentation sensor. To accurately and sensitively determine whether an anaerobic environment has formed at the bottom of tank 1, detector 9 specifically integrates a dissolved oxygen (DO) sensor, a redox potential (ORP) sensor, and a temperature sensor. Detector 9 can also employ other types of sensors as needed to detect the fermentation status.

[0034] like Figure 4 As shown, the electrically controlled rotating ring 10 is coaxially rotatably connected to the inner side of the sliding ring 7. Its specific driving structure can be as follows: a gear ring is fixedly connected to the outer side of the electrically controlled rotating ring 10, a second drive motor is fixedly connected inside the sliding ring 7, and a gear is fixedly connected to the second drive motor and meshes with the gear ring, thereby driving the electrically controlled rotating ring 10 to rotate relative to the sliding ring 7.

[0035] One end of the spacer 11 is fixedly connected to the sliding ring 7, and the other end is fixedly connected to the electrically controlled rotating ring 10. When the electrically controlled rotating ring 10 rotates relative to the sliding ring 7, one end of the spacer 11 rotates, thereby causing the middle part of the spacer 11 to gradually twist and gradually wrap around the corresponding sleeve 26.

[0036] like Figure 12 As shown, the spacer 11 in this embodiment adopts a specially designed three-layer sandwich flexible composite structure, which includes a high-strength flexible fabric layer 111 in the middle. In this embodiment, the flexible fabric layer 111 is preferably aramid woven fabric or carbon fiber woven fabric. Rubber layers 112 are fixedly connected to both opposite surfaces of the fabric layer 111. The design of the rubber layer 112 serves two purposes: firstly, it prevents the fabric layer from directly contacting the compost material and being corroded, thus providing protection; secondly, it increases the contact friction between the spacer 11 and the outer friction layer of the sleeve 26 when the spacer 11 is twisted, preventing slippage.

[0037] To further increase the friction between the spacer 11 and the sleeve 26, multiple friction protrusions or friction layers are provided on the outer surface of the sleeve 26.

[0038] Reference Figure 4 and Figure 9 The sliding ring 7 has an annular arc-shaped cavity 12 inside, and an arc-shaped filter plate 13 is fixedly connected inside the arc-shaped cavity 12. A spring-loaded corrugated telescopic tube 14 connects the sliding ring 7 and the filter plate 4. The top end of the spring-loaded corrugated telescopic tube 14 communicates with the inside of the arc-shaped cavity 12, and the bottom end passes through the filter plate 4 and is fixedly connected to the filter plate 4. In this way, the liquid produced in the normal fermentation zone above will pass through the arc-shaped filter plate 13 into the arc-shaped cavity 12, and then be directly guided to the space below the filter plate 4 through the spring-loaded corrugated telescopic tube 14, realizing the uninterrupted cross-zone discharge of waste liquid.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The outer side of the ventilation shaft 16 is fixedly connected to multiple stirring rods 23 that communicate with its interior, and each stirring rod 23 has multiple vent holes 24. The top of the tank body 1 is fixed with a first fixed shell 18, and the top of the ventilation shaft 16 has multiple first through holes 17 that communicate with the inner cavity of the first fixed shell 18. The first fixed shell 18 is connected to a first gas supply pipe 19 that introduces oxygen at a first pressure and a first flow rate.

[0040] A second fixed shell 21 is fixed to the bottom end of the tank body 1. The bottom end of the ventilation shaft 16 has multiple second through holes 20 that communicate with the inner cavity of the second fixed shell 21. The second fixed shell 21 is connected to a second gas supply pipe 22 that introduces oxygen at a second pressure and a second flow rate. Preferably, the second pressure is 2 to 3 times the first pressure, and the second flow rate is 2 to 3 times the first flow rate.

[0041] Within each section of the venting shaft 16 corresponding to each sleeve 26, the venting shaft 16 is slidably connected to multiple baffles 27 for cutting off the internal air passage. A second sliding cavity is provided on the venting shaft 16 to slidably engage with the baffles 27. For example... Figure 10As shown, a first sliding cavity is formed on the outer wall of the sleeve 26, and a piston block 29 is slidably connected in the first sliding cavity. A return spring 30 is connected between the piston block 29 and the sleeve 26. Multiple annular rotating shells 28 are also rotatably connected to the outer side of the ventilation shaft 16, and each annular rotating shell 28 corresponds to a multiple baffle 27. The annular rotating shell 28 communicates with the second sliding cavity where the corresponding baffle 27 is located.

[0042] The annular rotating shell 28 is connected to the first sliding chamber where the corresponding piston block 29 is located via a metal hose 31. The first sliding chamber, the second sliding chamber, and the metal hose 31 are all filled with extrusion fluid, such as hydraulic oil.

[0043] When the spacer 11 is twisted and tightly wrapped around the outside of the sleeve 26, the spacer 11 applies a radially inward clamping force to the sleeve 26, forcing the side wall of the sleeve 26 to undergo a radially inward contraction micro-deformation, causing the piston block 29 to move into the first sliding cavity. The extruded fluid in the first sliding cavity enters the annular rotating shell 28, and then pushes the baffle 27 to move, causing the baffle 27 to block the ventilation shaft 16.

[0044] A rectangular rod 32 is fixed to the top of the annular rotating shell 28, and the rectangular rod 32 is slidably connected to the sleeve 26.

[0045] Working principle: Initially, the sliding ring 7 is located in the lower region of the tank 1. The sleeve 26, under its own weight, is positioned at the top of the annular rotating shell 28, and the top of the rectangular rod 32 abuts against the sleeve 26. At this time, the piston block 29 is extended outwards under the elastic action of the spring 30, and due to hydraulic balance, the baffle 27 is retracted within the second sliding chamber. At this time, as... Figure 6 As shown, the interior of the ventilation shaft 16 is completely open from top to bottom, and is in a fully connected state.

[0046] Normal fermentation and intermittent stirring: The material is fed into the tank 1 through the feeding port 2 and then naturally fermented. During the fermentation process, the motor 15 starts at preset intervals, driving the ventilation shaft 16 and each stirring rod 23 to rotate synchronously. At the same time, the pump connected to the first gas supply pipe 19 injects atmospheric pressure oxygen into the first fixed shell 18, which enters the ventilation shaft 16 through the first through hole 17 and is discharged through the exhaust holes 24 of each stirring rod 23, providing oxygen for the aerobic microbial metabolism in the tank 1. The rotation of the stirring rods 23 ensures that the oxygen is fully mixed with the material.

[0047] State detection and boundary locking: Since the bottom material is prone to localized anaerobic putrefaction zones due to gravity compaction, the electric roller 8 with a brake is activated every once in a while, causing the sliding ring 7 to drive the detector 9 to slide up and down along the fixed rod 6 inside the tank 1 to monitor the material status at different heights online.

[0048] When detector 9 detects that an anaerobic putrefaction zone has been formed at the bottom, i.e., the compost has already decomposed, as sliding ring 7 moves upward, at the instant when detector 9 can no longer detect the signal of the anaerobic putrefaction zone, this height position is determined to be the highest boundary position of the anaerobic putrefaction zone, i.e., the boundary height.

[0049] The sleeve 26 adjacent to the boundary height of the anaerobic putrefaction zone is defined as the target sleeve 26. When the sliding ring 7 moves to the preset height, that is, the position corresponding to the target sleeve 26, the brake on the electric roller 8 with brake automatically locks, fixing the sliding ring 7 at the preset height.

[0050] The rotation of the partition cloth 11 achieves physical isolation and adaptive gas path cutoff: After the sliding ring 7 is locked, the electrically controlled rotating ring 10 rotates, causing one end of the spacer cloth 11 to rotate. Since the other end of the spacer cloth 11 is fixed on the stationary sliding ring 7, the spacer cloth 11 as a whole begins to undergo torsional deformation. As the number of torsional rotations increases, the diameter of the middle part of the spacer cloth 11 shrinks and wraps tightly around the target sleeve 26.

[0051] Because the fabric layer 111 is taut and cannot be stretched, and the double-sided rubber layer 112 is in close contact with the friction protrusions on the outside of the sleeve 26, a fixed connection is formed between the partition cloth 11 and the sleeve 26, which physically divides the inside of the tank 1 into an anaerobic putrefaction zone below the partition cloth 11 and a normal fermentation zone above the partition cloth 11, thus intercepting the upward spread of contamination from the putrefaction microorganisms at the bottom.

[0052] Meanwhile, as the spacer 11 is wrapped tightly around the sleeve 26, it pushes the piston block 29 to overcome the elastic force of the spring 30 and move into the target sleeve 26. The piston block 29 presses the extruded fluid in the first sliding chamber into the second sliding chamber where the baffle 27 is located through the metal hose 31 and the annular rotating shell 28, thereby driving the baffle 27 to block the venting shaft 16 and completely block and cut off the internal air passage of the venting shaft 16, dividing the interior of the venting shaft 16 into two independent parts.

[0053] Next, the brake on the electric roller 8 with the brake is unlocked, allowing it to rotate freely. Then, the motor 15 is started, driving the venting shaft 16 to rotate. The venting shaft 16 drives the stirring rod 23 to rotate, thus stirring the materials.

[0054] For the normal fermentation zone above, the first gas supply pipe 19 continues to inject atmospheric pressure oxygen into the ventilation shaft 16 above the sealing baffle 27, and discharges it through the stirring rod 23 above, maintaining efficient aerobic fermentation.

[0055] For the anaerobic putrefaction zone below, the second gas supply pipe 22 activates the high-pressure pump, injecting oxygen at a second pressure and second flow rate into the ventilation shaft 16 below the sealing baffle 27, which is then discharged through the stirring rod 23 below. Combined with the dispersing effect of the stirring rod, the high-pressure oxygen forcibly penetrates and breaks down the anaerobic environment of the compacted material at the bottom, initiating a rescue fermentation process.

[0056] At this time, because the target sleeve 26 is tightly wrapped and fixed by the partition cloth 11, the ventilation shaft 16 will rotate relative to the target sleeve 26 when it rotates. Under the action of the reciprocating spiral groove 25, the sleeve 26 moves up and down reciprocally relative to the ventilation shaft 16. The sleeve 26 drives the sliding ring 7 and the material in the normal fermentation zone above to move up and down reciprocally in the tank 1 through the taut partition cloth 11, which further increases the uniformity of oxygen and material mixing.

[0057] The liquid produced by the material above the partition cloth 11 during fermentation enters the arc-shaped cavity 12 through the arc-shaped filter plate 13, and then flows into the tank 1 below the filter plate 4 through the spring corrugated telescopic tube 14.

[0058] The gas produced during fermentation of the material above the partition cloth 11, as well as any excess oxygen, will be discharged through the exhaust pipe at the top of the tank 1. The gas produced during fermentation of the material below the partition cloth 11, as well as any excess oxygen, will be discharged through the filter plate 4 and the outlet 5.

[0059] After implementing the above-mentioned rescue process for a period of time, the ventilation shaft 16 is stopped rotating, and the injection of oxygen into the ventilation shaft 16 is stopped. The diaphragm 11 is opened by reverse control of the electronic control ring 10, the piston block 29 is reset under the action of the spring 30, and the baffle 27 is retracted.

[0060] Then, the sliding ring 7 drives the detector 9 to re-detect the bottom material. If the detector 9 detects that the indicators of the original bottom anaerobic putrefaction zone have returned to the normal fermentation range, it indicates that the high-pressure aeration rescue was successful. Afterwards, the material in tank 1 undergoes normal fermentation, intermittent stirring, and detection.

[0061] If detector 9 detects that the bottom material is still in an anaerobic putrefaction state and cannot be reversed, it indicates that this part of the material has completely failed. Rotate the electrically controlled rotating ring 10 to control the partition cloth 11 to tighten and wrap the target sleeve 26 again, re-establishing physical isolation. While keeping the upper normal fermentation zone firmly supported by the partition cloth 11 and sliding ring 7, manually or automatically open the discharge door 3 at the bottom of the tank 1 to separately remove the bottommost irreversible putrefied material from the tank 1.

[0062] After cleaning, close the discharge gate 3. Then, control the electrically controlled rotating ring 10 to rotate in the opposite direction, causing the partition cloth 11 to completely loosen and return to its initial state, thus removing the separation from the inside of the tank 1. Without the support of the partition cloth 11, the material inside the tank 1 naturally falls back to the bottom of the tank 1 under its own weight. The target sleeve 26 falls back to the top of the corresponding annular rotating shell 28 under its own weight, and the piston block 29 and baffle 27 return to their initial state. This allows the remaining material to continue normal fermentation and intermittent stirring, thereby minimizing losses.

[0063] Example 2: In this example, at least two detectors 9 are provided, and both detectors 9 are mounted on the sliding plate 7. One detector is positioned above the partition cloth 11, and the other is positioned below the partition cloth 11. The upper detector 9 is used to perform routine inspection work.

[0064] When the partition cloth 11 is twisted and deformed and its middle part shrinks and wraps tightly around the outside of the sleeve 26, the detector 9 below is located inside the anaerobic putrefaction zone, so that the material index parameters during the rescue fermentation process can be monitored by the detector 9 below without untying the partition cloth 11.

[0065] After a period of rescue efforts, if the rescue is successful and the material below returns to normal aerobic fermentation standards, the electrically controlled rotating ring 10 is reversed to release the partition cloth 11. The target sleeve 26 falls back under its own weight, and the corresponding piston block 29 moves outward and resets under the elastic action of the spring 30. The baffle 27 moves and resets, thus canceling the separation of the air passage inside the ventilation shaft 16. Finally, the brake of the electric roller 8 with brake is unlocked. The material in the tank 1 then proceeds with the normal fermentation process.

[0066] If the material at the bottom remains in an irreversible anaerobic putrefaction state, open the discharge door 3 at the bottom of tank 1 and clean out the waste material. After cleaning and closing the discharge door 3, control the electrically controlled rotating ring 10 to rotate in the opposite direction to loosen the partition cloth 11, restoring it to its initial relaxed state, thereby canceling the lifting and separating effect on the material inside tank 1. The material in a normal fermentation state will naturally fall back to the bottom of tank 1 under its own gravity, and then the normal fermentation process can continue.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
