Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a high-temperature aerobic fermentation tank. Background Technology

[0002] The high-temperature aerobic fermentation tank is constructed with a double-layered insulated stainless steel tank and has an internal stirring paddle, aeration system, and temperature and humidity sensors. Through forced ventilation and mechanical stirring, aerobic microorganisms such as Bacillus and Actinomycetes efficiently degrade organic matter at a high temperature of 55-75℃, achieving rapid composting. It is suitable for organic waste with high moisture content, such as kitchen waste, sludge, livestock and poultry manure, straw and distiller's grains, Chinese medicine residue, and food processing waste.

[0003] Chinese patent discloses a high-temperature aerobic fermentation tank (authorization announcement number CN220537718U). This patented technology suffers from uneven oxygen input and low heating efficiency, leading to long fermentation cycles and low organic fertilizer production efficiency. This application provides a high-temperature aerobic fermentation tank with a drive shaft inside the tank, on which a stirring rod is mounted. The stirring rod has a jet nozzle. During operation, high-temperature oxygen-rich steam enters the stirring rod through a guide pipe inside the drive shaft and then enters the tank through the jet nozzle. Compared to traditional oxygen injection, this solution allows for sufficient contact between oxygen and the material while providing the necessary temperature for fermentation. The tank also has baffles perpendicular or parallel to the side walls. The collision between the fermentation material and the baffles causes radial flow, preventing the formation of a central vortex and avoiding excessive stirring that could damage the mycelium of the fermenting microorganisms.

[0004] However, this patent still has shortcomings. While achieving uniform aeration, it makes cleaning the aeration structure difficult, requiring separate cleaning when the fermenter is empty. Sulfur-containing organic matter and proteins are decomposed by anaerobic bacteria in the anoxic area, forming hydrogen sulfide. High-salt raw materials such as kitchen waste and feces, combined with moisture evaporation in the high-temperature aerobic environment, cause sodium chloride / calcium sulfate to concentrate and precipitate. Acidic gases and salt crystals lead to equipment corrosion and scaling, inevitably requiring cleaning while the equipment is empty. Each cleaning session involves long downtime, affecting material fermentation, and has low cleaning efficiency. H2S accumulation also poses a risk of poisoning to workers. Therefore, those skilled in the art have provided a high-temperature aerobic fermenter to solve the problems mentioned in the background. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-temperature aerobic fermenter, comprising a fermenter, a cleaning cylinder, an arched plate, an installation pipe, and a second motor. The cleaning cylinder is located at the upper end of the fermenter, and a flow port is provided between the cleaning cylinder and the fermenter. An installation pipe is located inside the flow port, and one-way valves arranged in a ring array are provided on the outer wall of the installation pipe. An annular seat is located inside the cleaning cylinder, and a sleeve is fitted onto the outer side of the installation pipe. A rotating ring, rotatably mounted inside the annular seat, is fitted onto the outer wall of the sleeve. A third motor is located inside the upper end of the cleaning cylinder, and a gear ring is fitted onto the outer wall of the sleeve. A gear that meshes with the gear ring is located at the output end of the third motor. Brushes arranged in a ring array are provided on the inner wall of the sleeve. An arched plate is fitted onto one end of the installation pipe outside the cleaning cylinder. A second motor is located at one end of the cleaning cylinder, and a screw threaded onto the arched plate is located at the output end of the second motor. A pressurized air pump is located at the rear end of the cleaning cylinder.

[0008] Furthermore, a guide rod is provided at one end of the cleaning cylinder, and one end of the guide rod is slidably inserted into the inside of the arched plate; a limit ring is provided at the upper end of the screw.

[0009] Specifically, the arched plate, which is threaded onto the screw, is prevented from completely detaching from the screw by a limiting ring, and the guide rod is slidably installed inside the arched plate to guide its movement.

[0010] Furthermore, the upper end of the cleaning cylinder is provided with a water inlet pipe, the lower end of the cleaning cylinder is provided with a drain pipe, the lower end of the drain pipe is provided with a sealing plug, and the upper end of the cleaning cylinder is embedded with a sealing ring that is slidably installed with the installation pipe.

The installation pipe is slidably supported inside the cleaning cylinder through the sealing ring, and the opening and closing of the drain pipe is controlled by the sealing plug.

[0012] Furthermore, a sealed bearing is embedded inside the upper end of the mounting tube, and an insert tube is rotatably inserted inside the sealed bearing. A flexible tube connected to the output end of the pressurized air pump is provided at the upper end of the insert tube.

[0013] Specifically, the sealed bearing provides rotational support for the insertion tube, and the airflow delivered by the hose is effectively transported into the installation tube through the support tube.

[0014] Furthermore, the inner walls of the upper and lower sides of the ring seat are rotatably equipped with balls arranged in a ring array, and the inner walls of the upper and lower ends of the rotating ring are provided with ring rails that fit with the balls.

[0015] Specifically, the rotating ring guides the balls through the ring rail, reducing the rotational resistance and friction of the rotating ring and improving the rotational stability of the sleeve.

[0020] Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] This invention utilizes a high-pressure air pump to deliver gas into the installation pipe. The gas is then evenly distributed into the fermentation tank via longitudinally distributed one-way valves. Combined with the fermentation tank's built-in stirring structure, the gas undergoes thorough fermentation in a high-temperature, aerobic environment. Simultaneously, the installation pipe slides longitudinally inside the side of the fermentation tank. When cleaning is required, it is directly lifted into the cleaning cylinder and positioned inside the sleeve. A brush inside the sleeve scrapes the installation pipe and one-way valves. At this time, a cleaning solution is injected into the cleaning cylinder, which, in conjunction with the brush, performs the scrubbing. This allows for convenient cleaning of the gas delivery structure without shutting down the system. The automatic cleaning is convenient, time-saving, and efficient, avoiding workers being in a toxic environment and improving cleaning safety.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A ring seat 26 is provided inside the cleaning cylinder 5. A sleeve 21 is sleeved on the outer side of the installation pipe 9. A rotatable device is fitted on the outer wall of the sleeve 21 and is mounted inside the ring seat 26. The rotating ring 28 of the part, the motor 24 is installed inside the upper end of the cleaning cylinder 5, the gear ring 23 is sleeved on the outer wall of the sleeve 21, the output end of the motor 24 is provided with a gear 25 that meshes with the gear ring 23, the inner wall of the sleeve 21 is provided with brushes 22 arranged in a ring array, the mounting tube 9 is located on the outer side of the cleaning cylinder 5 and the arched plate 6 is sleeved on one end, the cleaning cylinder 5 is provided with a motor 19, the output end of the motor 19 is provided with a screw 18 that is threadedly installed with the arched plate 6, and the rear end of the cleaning cylinder 5 is provided with a pressurized air pump 15.

[0038] A guide rod 14 is provided at one end of the cleaning cylinder 5. One end of the guide rod 14 is slidably inserted into the inside of the arched plate 6. A limit ring 17 is provided at the upper end of the screw 18.

[0039] The upper end of the cleaning cylinder 5 is provided with a water inlet pipe 7, the lower end of the cleaning cylinder 5 is provided with a drain pipe 20, the lower end of the drain pipe 20 is provided with a sealing plug 1, and the upper end of the cleaning cylinder 5 is embedded with a sealing ring 29 that is slidably installed with the installation pipe 9.

[0040] A sealed bearing 30 is embedded inside the upper end of the mounting tube 9. A tube 31 is rotatably inserted inside the sealed bearing 30. A flexible hose 16 connected to the output end of the pressurized air pump 15 is provided at the upper end of the tube 31.

[0041] The inner walls of the upper and lower sides of the ring seat 26 are rotatably equipped with balls 27 arranged in a ring array, and the inner walls of the upper and lower ends of the rotating ring 28 are provided with ring rails that fit with the balls 27.

[0042] The lower end of the mounting pipe 9 is provided with a base plate 11 with a radius greater than that of the stroke port 8. The upper end of the fermentation tank 1 is provided with an exhaust pipe 4 controlled by a valve. The upper end of the fermentation tank 1 is provided with a feed inlet 2. The upper end of the feed inlet 2 is provided with a sealing plug 2.

[0043] A motor 3 is installed at the upper end of the fermentation tank 1. A rotating shaft 12 is installed at the output end of the motor 3 and is rotatably installed inside the fermentation tank 1. Stirring rods 13 arranged in a ring array are installed on the outer wall of the rotating shaft 12.

[0044] In this embodiment, during fermentation, motor 13 drives the rotating shaft 12 to drive the stirring rod 13 to mechanically stir the material. At the same time, the pressurized air pump 15 introduces high-temperature oxygen-rich steam into the installation pipe 9 through the insertion tube 31 via the hose 16. Finally, it is evenly sprayed into the fermentation tank 1 through the one-way valve nozzle 10 to promote full contact between oxygen and material and maintain a suitable temperature. When cleaning is required, motor 29 drives the screw 18 to rotate, which drives the arched plate 6 to rise longitudinally along the guide rod 14, so that the installation pipe 9 enters the cleaning cylinder 5 through the stroke port 8. Because motor 324 drives the gear 25 to mesh with the gear ring 23, it drives the rotating ring 28 to rotate along the ring seat 26. The brush 22 on the inner wall of the sleeve 21 rotates synchronously to scrape the outer wall of the installation pipe 9 and the one-way valve nozzle 10.

[0045] Simultaneously, cleaning liquid is injected into the cleaning cylinder 5 through the water inlet pipe 7. Soaking and brushing are combined to remove the blockage and salt crystals from the one-way valve nozzle 10. The waste liquid after cleaning is discharged through the drain pipe 20. After cleaning, the motor 2 19 is reversed to reset the installation pipe 9 into the fermentation tank 1. The bottom plate 11 covers the stroke port 8 to prevent liquid leakage, and the fermentation operation can be resumed.

[0046] Traditional fermenters 1, due to their fixed jet structure, are prone to clogging of the one-way valve 10 caused by material adhesion or salt crystallization. This requires manual cleaning after shutdown, which is inefficient and poses a risk of H2S poisoning. By using a liftable installation pipe 9, the one-way valve 10 is placed inside the material during fermentation to achieve uniform oxygen supply. During cleaning, it is raised into an independent cleaning cylinder 5, where rotating brushes 22 and circulating cleaning fluid automatically remove dirt. Maintenance can be completed without stopping the machine, significantly reducing cleaning time.

[0047] To prevent the cleaning solution from seeping into the fermenter 1 and affecting the materials, the annular array of one-way valves 10 and the mechanical stirring of the stirring rod 13 work together to enhance the contact efficiency between oxygen and materials. Combined with the high-pressure aerobic environment inside the fermenter 1, the materials are fully fermented. In addition, the independent design of the cleaning cylinder 5 prevents the fermenter 1 from being idle, improves the continuous operation capability, and reduces the risk of workers being exposed to toxic gases.

[0048] Addressing the issues of long downtime, severe equipment corrosion, and high worker safety risks associated with traditional cleaning technologies, this device solves these problems through its online cleaning function. The liftable jet structure allows for rapid switching between fermentation and cleaning modes, resolving the uneven oxygen supply issue caused by clogged one-way valve nozzles. The cleaning fluid circulation system effectively dissolves salt crystals and organic matter, reducing equipment corrosion. The automated cleaning process eliminates the need for manual entry into the tank, reducing the risk of exposure to toxic gases such as H2S. This achieves high efficiency and convenient maintenance in high-temperature aerobic fermentation, improving organic fertilizer production efficiency while ensuring equipment stability and operational safety. It is suitable for large-scale treatment of high-moisture organic waste such as kitchen waste and livestock manure.
