Description

Technical Field

[0001] This utility model relates to the field of anaerobic fermentation tank technology, and in particular to an anaerobic fermentation tank for high-concentration organic waste. Background Technology

[0002] With the development of agriculture, food processing, and municipal industries, the output of high-concentration organic waste has increased dramatically. Large quantities of waste, such as livestock manure, kitchen waste, and crop straw, have accumulated, causing serious environmental and resource problems. Anaerobic fermentation technology has emerged to address this need, enabling the reduction, harmlessness, and resource utilization of organic waste, converting it into biogas, biogas residue, and biogas slurry. A search revealed Chinese patent CN221854572U, which discloses an anaerobic fermentation tank for high-concentration organic waste, belonging to the field of anaerobic fermentation. The tank includes a tank body and a cover plate connected to the top wall of the tank. The inner wall of the cover plate is threaded with evenly distributed fixing bolts, one end of which passes through the cover plate and is connected to the tank. The tank is connected by threads, and a bearing ring is fixedly connected to the inner wall of the tank. A uniformly distributed sliding rod is slidably connected to the inner wall of the bearing ring. A set of separation plates is fixedly connected to the top wall of the sliding rod. A stirring rod is rotatably connected to the inner wall of the tank. A limiting groove is opened on the inner wall of the stirring rod. A telescopic rod is slidably connected to the inner wall of the stirring rod through the limiting groove. An anti-clogging component is connected to the outer wall of the telescopic rod to prevent the filter tank from clogging. A mixing component is connected to the outer wall of the stirring rod to improve the fermentation efficiency of organic matter. By setting the anti-clogging component, the separation plate is shaken, which makes it easier for organic matter to pass through the filter tank and makes it more convenient to use. The mixing component facilitates the stirring of organic matter from all sides, which improves the fermentation efficiency.

[0003] The high-concentration organic waste anaerobic fermentation tank device in the above-mentioned patent has the following shortcomings: the device improves the fermentation quality by chopping and stirring the organic waste, but the flat design of the bottom of the tank and the lack of a discharge mechanism make it difficult to discharge the fermented waste residue from the tank. Over time, the waste residue inside will be difficult to discharge, making the device less practical. Therefore, a high-concentration organic waste anaerobic fermentation tank was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-concentration anaerobic fermentation tank for organic waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-concentration anaerobic fermentation tank for organic waste includes a box body. A conical bottom end is fixedly connected to the bottom of the box body, and a discharge pipe is fixedly connected to the bottom of the conical bottom end. A cover is screwed to the bottom of the discharge pipe. A drive motor is fixedly connected to the middle of the top of the box body. A cylinder is fixedly connected to the bottom output end of the drive motor through the box body. A bottom plate is fixedly connected to the bottom of the cylinder.

A auger is fixedly connected to the bottom of the round rod at the discharge pipe.

[0007] As a further embodiment of this utility model, a conical cover is fixedly connected to the inner side of the box near the top. A through hole is opened in the middle of the bottom of the conical cover. The conical cover allows organic waste to fall through the cutter. Sliding rods are fixedly connected to both sides of the middle of the bottom of the conical cover. The same disc is slidably sleeved between the circumferential surfaces of the two sliding rods. Multiple sieve holes are opened at equal intervals at the bottom of the disc. Limiting blocks are fixedly connected to the bottom of the two sliding rods. A circular hole adapted to the sleeve is opened in the middle of the disc.

[0008] As a further embodiment of this utility model, a cylindrical inclined block is fixedly connected to the bottom of the disc, and the cylindrical inclined block is slidably sleeved on the circumferential surface of the sleeve. A protrusion is fixedly connected to the sleeve near the cylindrical inclined block. Through the cooperation of the cylindrical inclined block and the protrusion, the disc vibrates under the action of gravity as the sleeve rotates.

[0009] As a further embodiment of this utility model, a plurality of cutters are fixedly connected to the circumferential surface of the sleeve near the conical cover, and a plurality of stirring rods are fixedly connected to the circumferential surface of the sleeve at the bottom of the conical cover.

[0012] As a further embodiment of this utility model, the top of the box is provided with a feed inlet, and a sealing cap is screwed onto the feed inlet.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention employs a drive motor, a cylinder, ratchet, a ratchet gear, and a auger. When the drive motor rotates forward, the auger does not rotate. When material needs to be discharged, the drive motor is reversed, causing the cylinder to rotate. Through the cooperation of the auger and the conical bottom, waste is easily discharged from the tank, effectively solving the problem of difficult waste discharge mentioned in the background technology. This facilitates waste discharge, timely cleaning of the fermentation tank, effectively improves the efficiency of the fermentation tank, reduces adverse effects on the fermentation process, and avoids affecting the normal progress of the next round of fermentation.

[0015] This invention utilizes a cutter, stirring rod, disc, and protrusions to ensure that organic waste is shredded upon entering the chamber. The stirring rod further facilitates mixing with microorganisms, thereby improving fermentation quality. Attached Figure Description

[0024] Reference Figures 1-5 A high-concentration anaerobic fermentation tank for organic waste includes a housing 1. A conical bottom end 101 is fixedly connected to the bottom of the housing 1. A discharge pipe 102 is fixedly connected to the bottom of the conical bottom end 101. A cover 103 is screwed to the bottom of the discharge pipe 102. A drive motor 2 is fixedly connected to the middle of the top of the housing 1. A cylinder 9 is fixedly connected to the bottom of the drive motor 2 through the housing 1. A bottom plate 901 is fixedly connected to the bottom of the cylinder 9. A sleeve 4 is fixedly connected to the middle of the bottom of the bottom of the bottom plate 901. A fixing plate 501 is fixedly connected between the bottom of the inner side of the housing 1. A round rod 5 is rotatably sleeved in the middle of the fixing plate 501. A round hole adapted to the round rod 5 is opened in the middle of the fixing plate 501. The round rod 5 slides... The movable sleeve is installed on the inner circumference of the sleeve 4. The top of the round rod 5 is fixedly connected to the ratchet 503. Three ratchet teeth 902 are rotatably connected at equal intervals at the top edge of the inner side of the cylinder 9, and each ratchet tooth 902 is adapted to the ratchet 503. A spring is fixedly connected to the outer side of each ratchet tooth 902, and each spring is fixedly connected to the inner side wall of the cylinder 9. Through the arrangement of the ratchet teeth 902 and the ratchet 503, when the drive motor 2 reverses, the round rod 5 does not move. When the drive motor 2 rotates forward, the round rod 5 and the auger 502 rotate. The bottom of the round rod 5 is fixedly connected to the auger 502 at the discharge pipe 102. Through the arrangement of the auger 502, the waste material at the bottom of the conical bottom 101 can be discharged smoothly.

[0025] In this embodiment, a conical cover 6 is fixedly connected to the inner side of the box 1 near the top. Slide rods 601 are fixedly connected to both sides of the bottom middle of the conical cover 6. The same disc 7 is slidably sleeved between the circumferential surfaces of the two slide rods 601. Multiple sieve holes 701 are opened at equal intervals at the bottom of the disc 7. Limiting blocks are fixedly connected to the bottom of the two slide rods 601. A circular hole adapted to the sleeve 4 is opened in the middle of the disc 7.

[0026] In this embodiment, a cylindrical inclined block 702 is fixedly connected to the bottom of the disc 7, and the cylindrical inclined block 702 is slidably sleeved on the circumferential surface of the sleeve 4. A protrusion 8 is fixedly connected to the sleeve 4 near the cylindrical inclined block 702. Through the cooperation of the cylindrical inclined block 702 and the protrusion 8, under the action of gravity, the disc 7 vibrates continuously up and down as the sleeve 4 rotates.

[0027] In this embodiment, multiple cutters 404 are fixedly connected to the circumferential surface of the sleeve 4 near the conical cover 6. The multiple cutters 404 ensure that the organic waste at the bottom of the conical cover 6 and the top of the disc 7 is chopped and fed into the bottom of the box 1. Multiple stirring rods 403 are fixedly connected to the circumferential surface of the sleeve 4 at the bottom of the conical cover 6. The multiple stirring rods 403 ensure that the waste organic matter and microorganisms are fully mixed. A low rod 401 is fixedly connected to the bottom of the sleeve 4, and a round hole adapted to the round rod 5 is opened in the middle of the low rod 401.

[0028] In this embodiment, scrapers 402 are fixedly connected to both ends of the top of the low rod 401. Both scrapers 402 are in contact with the adjacent box 1. The scrapers 402 can prevent organic waste from adhering to the inner wall of the box 1.

[0029] In this embodiment, an exhaust pipe 3 is fixedly connected to one side of the box 1, and a solenoid valve 301 is fixedly installed on the exhaust pipe 3. The exhaust pipe 3 and the solenoid valve 301 facilitate the discharge of biogas after fermentation.

[0030] In this embodiment, a feed inlet 104 is provided on the top of the box 1, and a sealing cap is screwed onto the feed inlet 104.

[0031] Working principle: During use, close the cover 103, open the drive motor 2 and the sealing cover on the top of the feed inlet 104, and add organic waste into the inner wall of the box 1 through the feed inlet 104. Due to the rotation of the drive motor 2, the organic waste entering the conical shroud 6 is shredded by the cutter 404 through the rotation of the sleeve 4 and the cutter 404. At the same time, as the sleeve 4 rotates with the protrusion 8, the disc 7 vibrates up and down under the cooperation of the cylindrical inclined block 702 and gravity, so that the shredded organic waste enters the bottom of the box 1 through the screen holes 701. At the same time, add an appropriate amount of microorganisms, close the top of the feed inlet 104. The sealed cover isolates oxygen, and the drive motor 2 continues to rotate. The stirring rod 403 and scraper 402 stir the organic waste and microorganisms, and then the fermentation reaction takes place. When the fermentation is completed, the biogas produced is discharged through the exhaust pipe 3. Then the drive motor 2 is turned in reverse. The ratchet 902 and ratchet gear 503 make the round rod 5 rotate with the drive motor 2, which makes the auger 502 rotate. This allows the fermented waste residue to be discharged from the discharge pipe 102 without clogging the inside of the box 1. At the same time, the conical cover 6 and the conical bottom 101 further prevent the organic waste from clogging.
