[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0043] Example 1:

[0044] like Figures 1 to 12 As shown, a biological fermentation tank includes a fermentation tank body 1.

[0045] A synchronous shaft 23 is installed inside the fermentation tank body 1, and a stirring assembly is installed on the synchronous shaft 23. The stirring assembly includes a sleeve 24, a stirring base plate 241 is installed on the back of the sleeve 24, and an expansion plate 242 is plugged into the stirring base plate 241; this design enables the stirring range to be flexibly expanded according to actual needs, ensuring that the fermentation raw materials can be fully stirred in every corner of the tank, greatly improving the uniformity of raw material mixing, significantly promoting the contact frequency between microorganisms and nutrients, and thereby effectively accelerating the fermentation reaction speed, greatly improving the production amount and quality of fermentation products.

[0046] The fermenter body 1 also houses a deflection assembly for changing the angle of the stirring base 241. This assembly includes a circular frame 3, which is slidably connected to a rocker arm 34 mounted at the center of rotation of the sleeve 24. The bottom of the frame 3 aligns with the wavy guide rail 331 on the fermenter body 1. This unique structure allows the frame 3 to flexibly move up and down in response to the undulations of the wavy guide rail 331 during operation. This coordinated operation with the rocker arm 34 drives the sleeve 24 and stirring base 241 to change angles. This multi-angle stirring method comprehensively covers every area within the fermenter, fundamentally eliminating the occurrence of localized dead zones and ensuring that every portion of raw material fully participates in fermentation, laying a solid foundation for an efficient and stable fermentation process.

[0047] The fermentation tank body 1 is also equipped with an expansion component that changes the stirring area during the movement of the deflection component. The expansion component includes an extrusion block 36 installed on the side wall of the synchronization shaft 23 and having a V-shaped groove 361. The V-shaped groove is used to guide the expansion plate 242 to slide out from the stirring base plate 241; when the stirring base plate 241 rotates to an inclined state under the action of the deflection component, the distance between the end of the stirring base plate 241 and the outer shell of the fermentation tank body 1 will become longer accordingly. At this time, the expansion component responds quickly, and the expansion plate 242 extends in time under the guidance of the V-shaped groove 361, perfectly filling the stirring blank area caused by the increase in the spacing, further expanding the stirring range, and making the stirring effect more comprehensive and in-depth, effectively ensuring the uniformity and stability of the raw material mixing during the fermentation process.

[0048] The fermentation tank body 1 is also equipped with a collection assembly that collects raw materials toward the stirring assembly. This collection assembly includes a relatively swinging clamp 433 that swings along an inner groove 421 defined by the rotational center of the sleeve 24. During operation, the swinging of clamp 433 cleverly directs the raw materials dispersed within the tank toward the stirring assembly, resulting in a more concentrated distribution of the raw materials. This design greatly enhances the stirring assembly's effect on the raw materials, effectively reduces energy loss during the stirring process, significantly accelerates the mixing of raw materials, provides a more favorable environment for microbial growth and fermentation, and effectively promotes the efficient development of the fermentation reaction.

[0049] like Figures 1 to 12As shown, in a specific embodiment, a sight glass 14 is provided on the side wall of the fermentation tank body 1, through which the operator can observe the internal conditions of the fermentation tank body in real time and intuitively, timely grasp the fermentation process, and provide a basis for precise control. An exhaust pipe 15 is also installed on the side wall of the fermentation tank body 1. The exhaust pipe is used to discharge the exhaust gas generated during the fermentation process in a timely manner, maintain the stability of the gas environment in the tank, and ensure the smooth progress of the fermentation reaction. A spare pipe 16 and a feeding hopper 17 are installed on the top of the fermentation tank body 1. Suitable valves are installed inside the spare pipe 16 and the feeding hopper 17. The above structure is convenient for adding special materials or performing emergency operations according to actual needs during the fermentation process. A feed pipe 13 is also installed on the fermentation tank body 1, and a cover plate 131 is installed on the feed pipe 13 by bolts. This design not only ensures the convenience of feeding, but also ensures the good sealing of the tank body after the feeding is completed, preventing external impurities from entering and affecting the fermentation effect.

[0050] like Figures 1 to 12 As shown, further, four support legs 12 are installed at the bottom of the fermentation tank body 1, and an adjustment frame 121 is installed at the bottom of the four support legs 12 by screwing. The setting of the adjustment frame 121 enables the fermentation tank to flexibly adjust the height according to different working scenarios and needs, thereby enhancing the versatility and adaptability of the equipment. A discharge port 11 is provided at the bottom of the fermentation tank body 1. The discharge port 11 is interconnected with the inner cavity of the fermentation tank body 1, and a sealing plate 111 is installed at the bottom of the discharge port 11. After the fermentation is completed, the sealing plate 111 can be easily opened to discharge the fermentation product through the discharge port 11, and during the fermentation process, the sealing plate 111 can effectively ensure the sealing of the tank body.

[0051] Example 2:

[0052] The difference between Example 1 and this example is that: Figures 1 to 12 As shown, a back plate 22 is mounted on top of the fermenter body 1, to which a drive motor 2 is bolted. A coupling 21 is mounted on the output end of the drive motor 2. A synchronous shaft 23 is mounted at the rotation center of the coupling 21, and the synchronous shaft 23 flexibly extends through the outer shell of the fermenter body 1. This structural design ensures that the power of the drive motor 2 can be efficiently and stably transmitted to the synchronous shaft 23, driving the stirring assembly, deflection assembly, expansion assembly, and convergence assembly to work together, providing continuous and powerful power support for the entire fermentation process, ensuring the precise operation of each component, and further improving fermentation efficiency and quality.

[0053] like Figures 1 to 12As shown, in a specific embodiment, a push rod 31 is mounted on the top of the roll-shaped frame 3. The top of the push rod 31 is movably inserted into a positioning cover 311 mounted on the side wall of the synchronization shaft 23. A top plate 312 is mounted on the top of the push rod 31. The top plate 312 slides in a chamber defined within the positioning cover 311. A compression spring 313 is provided between the side wall of the chamber and the end surface of the top plate 312. The compression direction of the compression spring 313 is aligned with the movement direction of the push rod 31. The compression spring 313 exerts a downward force on the push rod 31 at all times, ensuring that the roll-shaped frame 3 on the push rod 31 can always fit in contact with the wave guide rail 331.

[0054] like Figures 1 to 12 As shown, the bottom of the circular frame 3 is mounted with a push rod 32, and a ball 321 is mounted at the bottom of the push rod 32. The ball 321 rolls on the surface of a wave guide 331. A guide block 33 is mounted at the bottom of the wave guide 331, and the guide block 33 is mounted on the bottom of the fermenter body 1. A synchronization frame 343 is mounted on the side wall of the circular frame 3, and a slide rod 342 is mounted on the synchronization frame 343. A rocker arm 34 has a strip groove 341 formed on its surface, and the slide rod 342 slides within the strip groove 341. A connecting frame 243 is rotatably mounted on the side wall of the sleeve 24, and the connecting frame 243 is mounted on the side wall of the synchronization shaft 23, with the rocker arm 34 located outside the connecting frame 243. This series of precise structural connections and coordination enables the circular frame 3, guided by the wave guide 331, to accurately drive the sleeve 24 and the stirring base 241 to change angles, achieving all-round, seamless stirring, further optimizing the stirring effect and improving the mixing quality of the fermentation raw materials.

[0055] Example 3:

[0056] The difference between Example 2 and this example is that: Figures 1 to 12 As shown, a synchronization rod 35 is movably inserted into the sleeve 24. One end of the synchronization rod 35 is connected to the expansion plate 242. The other end of the synchronization rod 35 is installed with a guide ball 351, which is slidably set in the V-shaped groove 361. A baffle 352 is installed on the synchronization rod 35, and the baffle 352 is slidably set in the inner cavity of the sleeve 24. A return spring 353 is installed on the synchronization rod 35, and one end of the return spring 353 is clamped in the inner cavity of the sleeve 24, and the other end is clamped on the baffle 352. This structural design allows the expansion plate 242 to extend and retract more smoothly and accurately under the guidance of the V-shaped groove 361. When the stirring base plate 241 tilts, the expansion plate 242 is extended in time to expand the stirring area, and can be quickly reset when not needed, ensuring the efficiency and flexibility of the stirring process and further improving the adaptability of the equipment to different fermentation conditions.

[0057] like Figures 1 to 12As shown, in a specific embodiment, the collecting assembly includes a fixing plate 434 installed at the bottom of the synchronous shaft 23, and a clamping arm 43 is rotatably installed on the fixing plate 434, and the clamping arm 43 and the clamping plate 433 are connected to each other. A notch 431 is provided on the clamping arm 43, and a fixing block 432 is slidably provided on the notch 431, and a push plate 432 is installed on the fixing block 432, and a slide plate 41 is installed on the top of the push plate 4. The slide plate 41 and the limit rod 411 installed on the side wall of the synchronous shaft 23 are movably penetrated, and a limit plate 412 is installed at the end of the limit rod 411, and a limit spring 413 is sleeved on the limit rod 411. One end of the limit spring 413 is clamped on the side wall of the synchronous shaft 23, and the other end of the limit spring 413 is clamped on the slide plate 41, and a protrusion 422 is installed on the side wall of the push plate 4, and a turntable 42 is installed at the rotation center of the sleeve 24, and the protrusion 422 is fitted with the inner groove 421 opened on the side wall of the turntable 42. The above structure enables the gathering component to achieve relative swinging of the clamping plate 433 through the precise cooperation between the turntable 42 and the push plate 4 when working, and efficiently gather the raw materials to the stirring component, further improving the concentration of the raw materials, enhancing the stirring effect, reducing energy waste, accelerating the mixing speed of the raw materials, and effectively promoting the rapid progress of the fermentation reaction.

[0058] The present invention also discloses a biological fermentation system, comprising a controller and a monitoring module and a control module electrically connected to the controller;

[0059] The monitoring module includes a temperature sensor, a pH sensor, and a dissolved oxygen sensor arranged inside the fermentation tank body 1, which are used to monitor the temperature, pH, and dissolved oxygen concentration data in the fermentation environment in real time and transmit the data to the controller; the control module includes a heating device, a cooling device, a feeding device, and a ventilation device connected to the fermentation tank body 1. The controller controls the heating device and the cooling device to adjust the temperature in the fermentation tank, controls the feeding device to add nutrients, and controls the ventilation device to adjust the gas composition and flow in the tank according to the data feedback from the monitoring module, so as to maintain the biological fermentation process in the optimal environmental conditions.

[0060] The implementation principle of a biological fermentation tank and a fermentation system thereof of the present invention is as follows:

[0061] When it is necessary to stir the fermentation raw materials inside the fermentation tank body 1.

[0062] The operator activates drive motor 2, which rotates through coupling 21, driving synchronous shaft 23. This in turn drives the stirring assembly, deflection assembly, expansion assembly, and collection assembly to work in tandem. This collaborative operation allows each component to work together, significantly improving the overall efficiency of the fermenter and avoiding issues such as uneven stirring and irrational material distribution that can arise when a single component operates.

[0063] During operation of the stirring assembly, the sleeve 24 rotates along with the synchronous shaft 23, driving the stirring base 241 to stir the raw materials in the fermentation tank body 1. Continuous stirring by the stirring base 241 allows the fermentation raw materials to be fully mixed, accelerates the contact between microorganisms and nutrients, promotes the fermentation reaction, and increases the production rate of the fermentation product.

[0064] During the rotation of the stirring assembly, the deflection assembly comes into play, causing the ball 321 at the bottom of the circular frame 3 to roll along the wavy guide rail 331. Due to the undulating shape of the wavy guide rail 331, the circular frame 3 moves up and down. At the same time, the circular frame 3 is slidably connected to the rocker arm 34 via the slide rod 342, ultimately driving the sleeve 24 and the stirring base 241 to change angles. The advantage of this design is that by changing the stirring angle, the raw materials at different locations in the fermentation tank can be stirred, effectively avoiding the occurrence of localized stirring dead spots and ensuring that all raw materials in the tank are fully stirred.

[0065] During this process, the expansion assembly begins to operate, causing the synchronization rod 35 on the expansion plate 242 to deflect synchronously. During this deflection, when the guide ball 351 at one end of the synchronization rod 35 contacts the V-groove 361 of the extrusion block 36, the synchronization rod 35, guided by the V-groove 361, overcomes the elastic force of the return spring 353 and pushes the expansion plate 242 out of the stirring base plate 241. This is because when the stirring base plate 241 rotates to the tilted state, the distance between the end of the stirring base plate 241 and the outer shell of the fermentation tank body 1 increases. At this time, the extension plate 242 extends, just enough to fill the mixing gap caused by this increased distance, thereby increasing the mixing area, making the mixing more comprehensive and sufficient, and allowing the raw materials to be mixed more evenly, which helps to improve the consistency and stability of the fermentation.

[0066] At the same time, the collection component is also working. When the sleeve 24 rotates, the coaxially connected turntable 42 rotates accordingly. When the inner groove 421 on the side wall of the turntable 42 fits with the protrusion 422 on the side wall of the push plate 4, the push plate 4, under the push of the turntable 42, drives the clamping arm 43 to rotate around the fixed plate 434 through the fixed block 432, causing the clamping plate 433 to swing relative to each other, gathering the raw materials to the stirring component, making the raw materials more concentrated and enhancing the stirring effect. The collection component concentrates the raw materials, allowing the stirring component to act on the raw materials more efficiently during stirring, reducing energy waste, and at the same time speeding up the mixing speed of the raw materials and improving the fermentation reaction rate.

[0067] The fermentation system plays a role throughout the fermentation process. The temperature sensor, pH sensor, and dissolved oxygen sensor monitor the temperature, pH value, and dissolved oxygen concentration data in the fermentation tank body 1 in real time, and transmit these data to the controller. Based on the received data, if the temperature is too high, the controller controls the cooling device to start cooling; if the temperature is too low, the controller controls the heating device to increase the temperature. When the pH value or dissolved oxygen concentration deviates from the optimal value, the controller controls the feeding device to add the corresponding regulating substance, or controls the ventilation device to adjust the gas flow and composition, so as to maintain the biological fermentation process in the optimal environmental conditions at all times and ensure that the fermentation process is carried out efficiently and stably. The fermentation system accurately controls the environmental parameters in real time, which can provide the most suitable conditions for microbial growth and fermentation reactions, effectively shorten the fermentation cycle, improve the yield and quality of fermentation products, reduce production costs, and enhance the competitiveness of products in the market.
