Description

Technical Field

[0001] This utility model relates to the field of bioengineering technology, and in particular to a reaction tank for fermentation of lactic acid bacteria in microbial distiller's grains feed. Background Technology

[0002] Microbial distillers' grains fermentation reactors provide a sealed environment for lactic acid bacteria fermentation. By controlling conditions such as temperature and humidity, lactic acid bacteria decompose sugars and other components in the distillers' grains under suitable conditions, producing beneficial substances such as lactic acid. It is mainly used in animal husbandry. For example, in cattle and sheep farming, fermented distillers' grains are more nutritious, palatable, and can increase feed intake, reduce feed costs, and promote healthy livestock growth.

[0003] A fermentation reactor typically consists of a tank body, a temperature controller, inlet and outlet ports, and an exhaust port. The tank body provides a closed fermentation space to prevent contamination by other microorganisms. The temperature controller ensures a suitable fermentation environment for the fermenting material. The exhaust port removes carbon dioxide produced during fermentation. The inlet port is used to add the treated fermenting material, and the outlet port allows the fermented material to flow out of the tank based on its fluid properties. In existing technologies, some fermentation reactors rely on the fluid properties of the fermented material to allow the fermented material to flow out of the reactor. However, this can lead to a situation where the fermented material becomes too viscous, resulting in poor flowability and accumulation at the discharge port, causing blockages and significantly impacting subsequent discharge. To address this issue, a reaction tank for microbial fermentation of distillers' grains with lactic acid bacteria is proposed. Utility Model Content

As a further description of the above technical solution: The outer wall of the connecting rod is slidably connected to a guide ring, the outer wall of the guide ring is fixedly connected to the bottom of the baffle, and the other end of the connecting rod is fixedly connected to one side of the outer wall of the vibrating plate.

[0006] This utility model has the following beneficial effects: 1.

The rotation of the eccentric wheel drives the rotating column at the bottom to rotate, and the rotation of the rotating column drives the rotating plate to rotate. The rotation of the rotating plate drives the connecting rod to reciprocate through the action of the rotating rod.

At this time, the insulation sleeve can keep the internal environment warm while preventing the heat from being directly transferred to the fermentation material inside the tank, which would cause the fermentation material to become inactive due to excessive temperature, thus providing a better fermentation environment for the fermentation material.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a reaction tank for microbial fermentation of lactic acid bacteria from distillers' grains, comprising a tank body 1. The inner wall of the tank body 1 is provided with a heating component for uniformly heating the internal temperature, providing a suitable temperature environment for lactic acid bacteria fermentation. The outer wall of the tank body 1 has a discharge port, and baffles 2 are fixedly connected to both sides of the discharge port. The baffles 2 are used to fix and support related components. A vibrating plate 3 is slidably connected to the inner wall of the baffles 2. The vibrating plate 3 vibrates the viscous material at the discharge port through reciprocating motion to avoid discharge blockage. A fixing plate 15 is fixedly connected to the outer wall of the baffles 2. The fixing plate 15 is used to install and fix components such as a drive motor 14. The drive motor 14 is fixedly connected to the outer wall of the fixing plate 15. After the drive motor 14 is started, it drives the fixing column 12 to rotate.

[0012] A fixed column 12 is fixedly connected to the drive end of the drive motor 14, and an eccentric wheel 29 is fixedly connected to the other end of the fixed column 12. The rotation of the fixed column 12 drives the eccentric wheel 29 to rotate. The rotating bearing 13 facilitates the rotation of the fixed column 12 on the inner wall of the fixed plate 15. A connecting bearing 10 is fixedly connected to the bottom of the eccentric wheel 29, and a rotating column 11 is fixedly connected to the inner wall of the connecting bearing 10. The rotation of the eccentric wheel 29 drives the rotating column 11 at the bottom to rotate. The connecting bearing 10 facilitates the rotation of the rotating column 11 inside the eccentric wheel 29, so that the rotating column 11 can rotate with the rotation of the eccentric wheel 29. A rotating plate 9 is fixedly connected to the other end of the rotating column 11. The rotation of the rotating column 11 drives the rotating plate 9 to rotate. A rotating rod 8 is fixedly connected to the inner wall of the rotating plate 9. The rotation of the rotating plate 9 drives the connecting rod 7 to reciprocate through the action of the rotating rod 8. A connecting plate 4 is fixedly connected to the outer wall of the baffle 2. The connecting plate 4 is used to install and fix components such as the sliding rod 6.

[0013] A sliding rod 6 is slidably connected to the inner wall of the connecting plate 4. The outer wall of the sliding rod 6 is fixedly connected to the inner wall of the vibrating plate 3. When the vibrating plate 3 reciprocates, the sliding rod 6 further ensures the linear motion of the vibrating plate 3. A limit sleeve 5 is fixedly connected to the outer wall of the sliding rod 6. The limit sleeve 5 is used to prevent the sliding rod 6 from coming off the connecting plate 4. A guide ring 30 is slidably connected to the outer wall of the connecting rod 7. The outer wall of the guide ring 30 is fixedly connected to the bottom of the baffle 2. The function of the guide ring 30 is to facilitate the control of the linear reciprocating motion of the connecting rod 7, thereby limiting the motion trajectory of the connecting rod 7. The other end of the connecting rod 7 is fixedly connected to the outer wall of one side of the vibrating plate 3. The reciprocating motion of the connecting rod 7 drives the vibrating plate 3 to reciprocate.

[0014] Reference Figures 2 to 4 The heating assembly includes a heating plate 16, the outer wall of which is fixedly connected to the inner wall of the tank 1. After the heating plate 16 is activated, it conducts heat to the inside of the heat transfer tube 17. The top of the heating plate 16 is fixedly connected to the heat transfer tube 17, which further transfers heat to the heat conduction coil 18, so that the heat can be quickly conducted to the entire interior of the tank 1, achieving uniform heating of the fermentation material inside the tank. The outer wall of the heat transfer tube 17 is fixedly connected to multiple heat conduction coils 18, which expand the area of ​​heat conduction, so that the heat can be distributed more widely and evenly inside the tank 1.

[0015] An insulation sleeve 19 is fixedly connected to the inner wall of the tank 1. The insulation sleeve 19 can keep the internal environment warm, reduce heat loss, and prevent heat from being directly transferred to the fermentation material inside the tank 1, thus preventing the fermentation material from becoming inactive due to excessive temperature. The outer walls of multiple heat-conducting rings 18 are in contact with the outer wall of the insulation sleeve 19, ensuring that heat can be effectively transferred to the inside of the insulation sleeve 19. An insulation inner liner 21 is fixedly connected to the inner wall of the insulation sleeve 19 to further enhance the insulation effect and provide a stable temperature environment for fermentation. A sealing ring 20 is set inside the top of the tank 1. The outer wall of the sealing ring 20 is in contact with the outer wall of the insulation sleeve 19, which plays a sealing role, preventing heat from being lost from the top of the tank 1 and also preventing external impurities from entering the tank.

[0016] An electric push rod 26 is fixedly connected to the inner wall of the insulated inner liner 21. A connecting block 28 is fixedly connected to the other end of the electric push rod 26. When the electric push rod 26 is activated, it drives the connecting block 28 and the sealing plate 27 connected thereto to move upward, opening the discharge port so that the material that has reacted well inside can flow outward. A sealing plate 27 is fixedly connected to the outer wall of the connecting block 28. The outer wall of the sealing plate 27 is slidably connected to the inner wall of the insulated inner liner 21. During the fermentation process, the sealing plate 27 plays a sealing role to prevent material leakage and the entry of external impurities. An electric push rod 22 is fixedly connected to the outer wall of the insulated inner liner 21. A fixing rod 23 is fixedly connected to the other end of the electric push rod 22. When the electric push rod 22 is activated, it can drive the fixing rod 23 and the sealing cover 24 to move, thereby sealing or opening the top of the tank 1.

[0017] A sealing cap 24 is fixedly connected to the bottom of the fixing rod 23. The sealing cap 24 is in contact with the top of the tank 1. During the fermentation process, the sealing cap 24 seals the top of the tank 1 to prevent heat loss and the entry of outside air and impurities. Multiple one-way vent valves 25 are fixedly connected to the top of the sealing cap 24. During the fermentation process, the one-way vent valves 25 can allow the internal fermentation material to expel excess gas, while preventing outside air from entering the tank, thus maintaining the gas pressure balance inside the tank and the stability of the fermentation environment.

[0018] Working principle: When it is necessary to discharge the reacted material inside the fermenter, the electric push rod 26 starts and drives the sealing plate 27 to move upward. At this time, the reactants inside flow outward. During the flow, due to the high viscosity of the reactants, the material accumulates at the outlet, causing a blockage. At this time, the drive motor 14 starts and drives the fixed column 12 to rotate. The rotating bearing 13 facilitates the rotation of the fixed column 12 on the inner wall of the fixed plate 15. The rotation of the fixed column 12 drives the eccentric wheel 29 to rotate. The rotation of the eccentric wheel 29 drives the rotating column 11 at the bottom to rotate. The connecting bearing 10 facilitates the rotation of the rotating column 11 on the inner wall of the fixed plate 15. The rotation of the inner wheel 29 and the rotation of the rotating column 11 drive the rotating plate 9 to rotate. The rotation of the rotating plate 9 drives the connecting rod 7 to reciprocate through the action of the rotating rod 8. The guide rod facilitates the linear reciprocating motion of the connecting rod 7. The reciprocating motion of the connecting rod 7 drives the vibrating plate 3 to reciprocate. While the vibrating plate 3 is reciprocating, the sliding rod 6 on the outside of the vibrating plate 3 further ensures the linear motion of the vibrating plate 3. The limiting sleeve 5 is used to prevent the sliding rod 6 from dislodging from the connecting plate 4. The reciprocating motion of the vibrating plate 3 vibrates the viscous material at the outlet to avoid blockage of the discharge.

[0019] When the fermentation material needs to react inside the tank 1, the heating plate 16 is activated first. The heating plate 16 conducts heat to the inside of the heat transfer tube 17, and the heat transfer tube 17 further transfers the heat to the heat conduction coil 18, so that the heat can be quickly conducted to the entire inside of the tank 1. At this time, the insulation sleeve 19 can keep the internal environment warm while preventing heat from being directly transferred to the fermentation material inside the tank 1, which would cause the fermentation material to become inactive due to excessive temperature. During this period, the one-way vent valve 25 can allow the internal fermentation material to expel excess gas.
