[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] This invention provides an anaerobic microbial feed fermentation device, such as... Figure 1 and Figure 2As shown, it includes: a tank body 1, the overall shape of the tank body 1 is cylindrical, the tank body 1 has a built-in stirring component for stirring materials, the top of the tank body 1 is equipped with a feed inlet 101 and the bottom of the tank body 1 is equipped with a discharge outlet 102, both the feed inlet 101 and the discharge outlet 102 are equipped with sealing plates to block the feed inlet 101 and the discharge outlet 102, and the side of the tank body 1 is equipped with an air extraction pipe 2, the air extraction pipe 2 is connected to the input end of an air extraction device, the air extraction device is an existing air extraction pump.

[0022] The materials were set as anaerobic microbial feed.

[0023] To stir the material inside the tank 1, a stirring component is used to stir the material. The stirring component includes a drive component 21, a rotating rod 22, and an arc plate 23. The drive component 21 is a drive motor as in the prior art. A rotating rod 22 is vertically arranged at the center of the inside of the tank 1. The drive component 21 is installed at the center of the top of the tank 1. The top of the rotating rod 22 is connected to the output end of the drive component 21. The surface of the rotating rod 22 is connected to the arc plate 23 by multiple side rods, and the outer arc surface of the arc plate 23 is attached to the inner side wall of the tank 1.

[0024] Specifically, the sealing plate of the feed inlet 101 is opened, and the material is fed into the tank 1 through the feed inlet 101. The material gradually accumulates inside the tank 1 until the material feeding is completed, and then the feed inlet 101 is sealed with the sealing plate.

[0025] The vacuum system is activated, using the vacuum pipe 2 to extract oxygen from inside tank 1, creating a negative pressure environment and reducing the oxygen content inside. The drive unit 21 is then activated, causing the rotating rod 22 at its output end to rotate clockwise inside tank 1. This clockwise rotation of the rod 22, along with multiple side rods, causes the arc-shaped plate 23 to rotate synchronously. The arc-shaped plate 23 slides along the inner wall of tank 1 using its outer arc surface, and in conjunction with the side rods, it stirs the material inside tank 1. After a period of stirring, the material undergoes anaerobic fermentation during the stirring process.

[0026] After fermentation is complete, the sealing plate of the discharge port 102 is opened, and the driving component 21 causes the rotating rod 22 to rotate in both directions, ensuring rapid discharge of materials.

[0027] In this embodiment, by rotating the rotating rod 22 in both directions, the counterclockwise rotating rod 22 uses the side rod to make the arc plate 23 scrape the material on the inner side wall of the tank 1, so as to avoid the material from accumulating on the inner side wall of the tank 1. The clockwise rotating rod 22 uses the side rod and the arc plate 23 to continue to stir the material, and the arc plate 23 can quickly discharge the material from the discharge port 102.

[0028] To extract oxygen from inside tank 1, gas is extracted using an extraction component and an extraction pipe 2. Figures 1 to 6The extraction components include: a top pipe 3, an extraction chamber 4, and an inner pipe 5. The inner pipe 5 has a built-in filter frame, which includes a bottom plate 6, a pressure plate 7, and a top ring 8. The top pipe 3 is fixed to the top surface of the tank body 1. An extraction chamber 4 is located on the top inner side of the tank body 1. The top pipe 3 is positioned at the top of the extraction chamber 4, and its bottom end is connected to the extraction chamber 4. The bottom end of the extraction pipe 2 is also connected to the extraction chamber 4. The inner pipe 5 is vertically inserted into a groove 401 on the bottom surface of the extraction chamber 4, and the top of the outer circumference of the inner pipe 5 is attached to the inner wall of the groove 401.

[0029] Since the filter frame is installed at the center of the inner tube 5, the bottom plate 6 is located at the center of the bottom surface of the inner tube 5, and the bottom plate 6 seals the bottom opening of the inner tube 5, the top surface of the bottom plate 6 is connected to the bottom surface of the top ring 8 by multiple side strips 9, the outer convex surface of the side strips 9 is attached to the inner side wall of the inner tube 5, the top ring 8 is located at the top opening of the inner tube 5, the pressure plate 7 is spirally installed on the top surface of the top ring 8, and the pressure plate 7 cooperates to seal the top opening of the inner tube 5. Filter holes are opened on the surfaces of the pressure plate 7 and the bottom plate 6. The filter frame has a built-in filter element, which is the filter cotton in the prior art.

[0030] The filter frame is secured to the top of the inner tube 5 by a connecting frame, which includes a side frame 10 and a cover plate 11. Two opposing side frames 10 are fixed to the outer circumference of the inner tube 5. The side frames 10 have an overall L-shaped structure. The top of the two side frames 10 are connected to the cover plate 11, which seals the top opening of the top tube 3. A vertical groove 301 is formed on the inner side wall of the top tube 3, and the side frames 10 slide inside the vertical groove 301. Two side grooves 402 are formed on the inner side wall of the through groove 401, and the side frames 10 are vertically inserted into the side grooves 402.

[0031] Specifically, filter elements are filled between multiple side strips 9, and the filter frame carrying the filter elements is vertically inserted into the inner tube 5. When the top surface of the top ring 8 is flush with the top surface of the inner tube 5, the pressure plate 7 is screwed onto the top of the top ring 8, and the filter frame cooperates to limit the pressure plate 7 until the bottom surface of the pressure plate 7 is attached to the top surface of the inner tube 5.

[0032] Holding the cover plate 11, the side frame 10 at the bottom of the cover plate 11 corresponds to the vertical groove 301 on the inner side wall of the top pipe 3. The cover plate 11 is moved down, causing the side frame 10 to move down inside the vertical groove 301 until the inner pipe 5 is inside the through groove 401. While the inner pipe 5 moves down inside the through groove 401, the cover plate 11 causes the side frame 10 to move down inside the side groove 402 until the bottom surface of the cover plate 11 is attached to the top opening of the top pipe 3. At this time, the inner pipe 5 and the filter frame block the through groove 401, and the locking part limits the side groove 402.

[0033] When the air extraction equipment is started, since the inlet 101 and outlet 102 are blocked, the air extraction equipment uses the air extraction pipe 2 to extract the air inside the air extraction chamber 4. The air extraction chamber 4 is under negative pressure, and the air inside the tank 1 enters the air extraction chamber 4 through the filter frame.

[0034] Air enters the inner tube 5 through multiple filter holes on the surface of the bottom plate 6. The filter holes on the surface of the bottom plate 6 filter out the material inside the tank 1, and the filter element inside the inner tube 5 adsorbs the mist material in the air. The filtered air enters the air extraction chamber 4 through the filter holes on the surface of the pressure plate 7. At this time, the air extraction pipe 2 extracts the filtered air inside the air extraction chamber 4, completing the oxygen extraction process of the tank 1.

[0035] In this embodiment, the top opening of the top pipe 3 is sealed by the cover plate 11, and the material inside the tank 1 is filtered by the filter rack to prevent the material from being discharged through the exhaust pipe 2, thereby preventing unfermented material from being discharged from the inside of the tank 1 and ensuring the fermentation effect of the material.

[0036] To lock the pressure plate 7 at the top of the inner tube 5, the filter frame is locked using a locking mechanism. Figure 3 , Figures 5 to 8 In the middle, the locking part includes: side block 12, outer plate 13 and sliding plate 14; two opposing side blocks 12 are provided on the outer side of the inner tube 5, the inner side of the side block 12 is attached to the outer side of the inner tube 5, the outer plate 13 is fixed on the outer side of the side block 12, the two side blocks 12 correspond one-to-one with the two side frames 10, the outer plate 13 on the outer side of the side block 12 is inserted into the slide groove 15, the outer side of the side block 12 is attached to the inner side wall of the side frame 10, the top surface of the side block 12 is provided with a top groove, and the sliding plate 14 is connected to the top groove by a sliding part.

[0037] The side frame 10 includes a vertical plate and a horizontal plate. The bottom end of the vertical plate is fixed to the outer side of the inner tube 5 by the horizontal plate. The bottom surface of the side block 12 is penetrated by the horizontal plate by the vertical rod 16, and the bottom end of the vertical rod 16 is screwed with a nut 17. The top surface of the nut 17 is attached to the bottom surface of the horizontal plate.

[0038] To limit the pressure plate 7, the sliding plate 14 is adjusted by a sliding part, which includes a square rod 18, a screw 19, and a fastening sleeve 20. The square rod 18 is fixed on both sides of the sliding plate 14, and the top groove is provided with square grooves 121 on both sides. The square rod 18 slides inside the square grooves 121. The screw 19 is fixed on the outer end of the square rod 18, and the fastening sleeve 20 is spirally sleeved on the surface of the screw 19.

[0039] Specifically, after the pressure plate 7 and the top ring 8 lock the filter frame, the side block 12 is pulled down. The outer plate 13 on the outer side of the side block 12 moves down inside the slide groove 15. The moving side block 12 makes the vertical rod 16 approach the horizontal plate until the bottom end of the vertical rod 16 penetrates the horizontal plate, and the nut 17 is screwed onto the bottom end of the vertical rod 16.

[0040] Loosen the fastening sleeve 20 and pull the slide plate 14. The slide plate 14 moves out of the top groove. The moving slide plate 14 causes the square rod 18 to slide inside the square groove 121 until the inner end of the slide plate 14 is at the top of the pressure plate 7. Tighten the fastening sleeve 20. The fastening sleeve 20 rotates on the surface of the screw 19. The rotating fastening sleeve 20 fits against the side of the side block 12. The screw engagement between the fastening sleeve 20 and the screw 19 completes the locking of the slide plate 14.

[0041] Tighten nut 17. The screw engagement between nut 17 and vertical rod 16 causes vertical rod 16 to move down inside the horizontal plate. The downward movement of vertical rod 16 causes side block 12 and locking part to move down. When the bottom surface of slide plate 14 is in contact with the top surface of pressure plate 7, the pressure of slide plate 14 causes the bottom surface of pressure plate 7 to be in contact with the opening on the top surface of inner tube 5, ensuring that the air inside tank 1 enters the air extraction chamber 4 through the filter frame.

[0042] In this embodiment, the screw engagement between the fastening sleeve 20 and the screw 19 facilitates locking the slide plate 14 at different positions on the top of the side block 12. Under the rotation effect of the nut 17, the slide plate 14 can limit the pressure plate 7 at the top opening of the inner tube 5, ensuring that the air inside the tank 1 enters the air extraction chamber 4 through the filter frame.

[0043] This invention also provides a method for fermenting anaerobic microbial feed, referring to... Figures 1 to 8 As shown, it includes the following steps: Open the sealing plate of the feed inlet 101 and feed the material into the tank 1 through the feed inlet 101. The material gradually accumulates inside the tank 1 until the material is fed in. Then, use the sealing plate to block the feed inlet 101.

[0044] Start the vacuum equipment. The vacuum equipment uses the vacuum pipe 2 to extract oxygen from inside the tank 1, so that the inside of the tank 1 is in a negative pressure state, thereby reducing the oxygen content inside the tank 1.

[0045] The material inside the tank 1 is stirred by a stirring component, and the material undergoes anaerobic fermentation during the stirring process.

[0046] After fermentation is complete, the sealing plate of the discharge port (102) is opened, and the driving component (21) causes the rotating rod (22) to rotate in both directions to ensure the rapid discharge of materials.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
