Description

A special fermentation tank for plant-based acid fermentation pulp with high bioavailability Technical Field

[0001] This invention belongs to the field of microbial fermentation tank technology, specifically referring to a special fermentation tank for plant-based acidic fermentation pulp with high bioavailability. Background Technology

[0002] Fermentation refers to the process of preparing microbial cells themselves, or their direct or secondary metabolites, by means of the life activities of microorganisms.

[0003] During fermentation, the fermentation tank needs to be stirred regularly to help the raw materials and microorganisms distribute nutrients evenly within the tank, ensuring that all microorganisms have access to sufficient nutrients to promote their growth and metabolic activities, thereby improving the utilization rate of microorganisms. Stirring can also improve heat transfer and mixing, helping to maintain the uniformity of temperature within the fermentation tank and control the acidity value.

[0004] However, traditional fermenters do not have a self-reversing stirring structure and cannot change the stirring direction inside the fermenter according to the growth status of microorganisms. This results in uneven distribution of nutrients and acidic environment inside the fermenter, which inhibits the activity of microorganisms. Therefore, in order to break the regularity of stirring in the fermenter and improve the bioavailability inside the fermenter, a special fermenter for plant-based acidic fermentation pulp with high bioavailability is proposed. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a dedicated fermenter for plant-based acidic fermentation pulp with high bioavailability. By incorporating a reversing component and a pressure stabilizing component, when the gas pressure inside the fermenter increases, the pressure stabilizing component releases the pressure and simultaneously drives the reversing component to change the transmission direction of the stirring shaft. This allows the fermenter to automatically adjust the frequency of the stirring shaft's rotation according to the growth status of the microorganisms, effectively solving the problems of current fermenters being unable to automatically change the stirring direction and having low bioavailability.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a special fermenter for plant-based acidic fermentation pulp with high bioavailability, including a tank assembly, a dividing box, a reversing assembly, an outer shell frame, a pressure stabilizing assembly, and a synchronous belt.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] (1) In order to solve the problem that traditional fermenters cannot change the direction of stirring on their own, resulting in uneven distribution of nutrients and acidic environment in the fermenter and inhibition of microbial activity, the present invention sets up a reversing component and a pressure stabilizing component, which can change the rotation direction of the stirring shaft on its own during the process of balancing the gas pressure in the fermenter, thereby breaking the regularity of stirring in the fermenter and effectively improving the uniformity of the microbial fermentation environment and bioavailability.

[0018] (2) In this process, the pressure stabilizing component drives the reversing component to change the transmission direction of the stirring shaft. During the depressurization process, the pressure stabilizing component causes the screw to rotate and the rotating rod to rotate under the transmission action of the synchronous belt, so that the reversing plate can be in different positions, and the spindle can mesh with the first bevel gear or the second bevel gear respectively, so that the transmission from the active bevel gear to the stirring shaft can go through different transmission processes, change the rotation direction of the stirring shaft, and realize the self-change of the stirring direction in the fermenter during the depressurization process.

[0019] (3) In addition, when the gas pressure in the fermenter is too high, the trigger block triggers the elastic telescopic rod to retract, and under the tension of the reset spring, the sealing head is separated from the exhaust port, thereby discharging the gas in the fermenter from the sliding sleeve, so that the gas pressure in the fermenter is kept within a suitable range.

[0020] (4) In addition, the gas pressure in the fermenter changes with the activity of microorganisms, and the pressure relief frequency of the pressure stabilizing component changes with the activity of microorganisms. Thus, it can automatically change the frequency of the stirring shaft rotation according to the growth status of microorganisms, thereby improving the activity and utilization of microorganisms in the fermenter.

[0036] As shown in Figures 1-11, this invention proposes a special fermenter for plant-based acidic fermentation pulp with high bioavailability, including a tank assembly 1, a dividing box 2, a reversing assembly 3, an outer frame 4, a pressure stabilizing assembly 5, and a synchronous belt 6.

The bracket 305 is fixedly connected to... On the dividing box 2, the first bevel gear 306 is rotatably connected to the bracket 305, and the second bevel gear 307 is rotatably connected to the outer casing 4. Both the first bevel gear 306 and the second bevel gear 307 have keyways 308 in their middle sections.

The second bevel gear 307 rotates, and the first bevel gear 306 and the second bevel gear 307 rotate in opposite directions. When the spline shaft 303 engages with the keyway 308 on the first bevel gear 306, the rotation of the driving bevel gear 309 drives the stirring shaft 301 to rotate via the first bevel gear 306, the spline shaft 303, and the spline 302. The gear shifting transmission structure includes a fixed plate 312, a worm gear 313, a turntable 314, a lifting frame 317, and a guide telescopic rod 319. The fixed plate 312 is fixedly connected to the outer casing 4, and the worm gear 313 rotates... The rotating plate 314 is fixedly connected to the fixed plate 312, the turntable 314 is fixedly connected to the worm gear 313, the eccentric column 315 is fixedly connected to the turntable 314, the lifting frame 317 is provided with a sliding groove 318, the sliding slider 316 is slidably connected in the sliding groove 318, the sliding slider 316 is rotatably connected to the eccentric column 315, the two ends of the guide telescopic rod 319 are fixedly connected to the lifting frame 317 and the outer shell frame 4 respectively, the guide telescopic rod 319 provides guidance for the lifting frame 317 to move up and down, and the reversing plate 304 is fixedly connected to the lifting frame 317.

[0038] The pressure relief structure includes a pressure testing cylinder 501, a sensing piston 502, a drive rod 503, a sealing sleeve 504, a sliding sleeve 505, a sealing shaft 507, a lifting platform 510, a tension spring 511, and a return spring 512.

The gas pressure inside the fermenter can push the sensing piston 502 to move. The drive rod 503 is fixedly connected to the sensing piston 502. The sealing sleeve 504 is fixedly connected to the dividing box 2, and the sliding sleeve 505 is slidably connected inside the sealing sleeve 504. The bottom of the sliding sleeve 505 is provided with... The fermenter has an exhaust port 506, a sliding sleeve 505, and a sealing shaft 507, all of which extend into the interior of the tank assembly 1. A sealing head 508 is located at the bottom of the sealing shaft 507, controlling the opening and closing of the exhaust port 506. A cavity exists between the sliding sleeve 505 and the sealing shaft 507. When the exhaust port 506 and the sealing head 508 disengage, gas inside the fermenter is discharged from the cavity. A limit guide rod 509 is fixedly connected to the bottom of the lifting platform 510, and the limit guide rod 509 is slidably connected to the sealing shaft 507. Two ends of a tension spring 511 are fixedly connected to the lifting platform 510 and the sealing shaft 507, respectively, and the tension spring 511 maintains the connection between the exhaust port 506 and the sealing head 508. A tight fit maintains a seal. A reset spring 512 is located between the lifting platform 510 and the dividing box 2. When the bottom of the trigger block 515 and the top of the push block 518 disengage, the tension of the reset spring 512 causes the lifting platform 510 and the sealing shaft 507 to move downwards as a whole, thereby causing the exhaust port 506 to disengage from the sealing head 508. A connecting plate 513 is fixedly connected to the drive rod 503, and a sliding sleeve 505 is fixedly connected to the connecting plate 513. The transmission structure includes a screw rod 523, a one-way ratchet 524, a driven ratchet 525, and a driving synchronous wheel 526. The screw rod 523 is rotatably connected to the outer casing 4, and the one-way ratchet 524 is fixedly connected to the screw rod 523. The moving ratchet 525 is rotatably connected to the housing frame 4. The driven ratchet 525 is engaged with the one-way ratchet 524. When the threaded block 519 moves upward, the rotation of the one-way ratchet 524 cannot drive the driven ratchet 525 to rotate. When the threaded block 519 moves downward, the rotation of the one-way ratchet 524 drives the driven ratchet 525 to rotate. The driving synchronous wheel 526 is fixedly connected to the driven ratchet 525. The top of the drive rod 503 is fixedly connected to the lifting plate 517. The threaded block 519 is fixedly connected to the lifting plate 517. The threaded block 519 is threadedly connected to the screw rod 523. When the threaded block 519 moves, it drives the screw rod 523 to rotate.

[0039] In addition, a drive motor 311 is fixedly installed on the outer casing 4, and the output end of the drive motor 311 is fixedly connected to the main shaft 310. The driving bevel gear 309 is fixedly connected to the main shaft 310. A rotating rod 320 is rotatably connected to the fixed plate 312, and a worm gear 321 is fixedly connected to the rotating rod 320. The worm gear 321 is meshed with the worm wheel 313. A driven synchronous pulley 322 is fixedly connected to the rotating rod 320. A synchronous belt 6 is installed on the driven synchronous pulley 322 and the driving synchronous pulley 526. During a depressurization process, under the deceleration action of the worm gear 321 and the worm wheel 313, the threaded block 519 moves down each time, driving the worm wheel 313 to rotate 180 degrees. This allows the flower shaft 303 to mesh with the first bevel gear 306 or the second bevel gear 307 respectively, thereby realizing the rotation of the stirring shaft 301.

[0040] In addition, the lifting platform 510 is provided with an elastic telescopic rod 514, and a trigger block 515 is fixedly connected to the elastic telescopic rod 514. A fixing block 516 is fixedly connected to the outer casing 4. The bottom of the fixing block 516 is set with an incline. The trigger block 515 is located below the fixing block 516. The top of the trigger block 515 is set with an incline, and the bottom of the trigger block 515 is set with a flat surface. A push block 518 is fixedly connected to one end of the lifting plate 517 near the trigger block 515. The top of the push block 518 is set with a flat surface, and the bottom of the push block 518 is set with an incline. A guide rail 520 is fixedly connected to the outer casing 4. The lifting platform 510 is slidably connected to the guide rail 520. A positioning block 521 is fixedly connected to the bottom of the guide rail 520. A slide rail 522 is fixedly connected to the outer casing 4. The lifting plate 517 is slidably connected to the slide rail 522.

[0041] In addition, the top of the tank assembly 1 is provided with a feed inlet 7, and the bottom of the tank assembly 1 is provided with a discharge outlet 8.

[0042] In terms of specific use and working principle, during biological fermentation in the fermenter, the gas produced by the activity of microorganisms increases the gas pressure inside the tank assembly 1. This gas pressure pushes the sensing piston 502 and drive rod 503 upwards, causing the top plane of the push block 518 to align with the bottom plane of the trigger block 515. This, in turn, lifts the trigger block 515 upwards. The lifting platform 510 and the sealing shaft 507 move upwards accordingly. The drive rod 503, through the connecting plate 513, drives the sliding sleeve 505 to move upwards synchronously. Under the tension of the tension spring 511, the sealing head 508 at the bottom of the sealing shaft 507 aligns with the exhaust port 506 at the bottom of the sliding sleeve 505, keeping the exhaust port 506 closed. When the inclined surface at the top of the trigger block 515 contacts the inclined surface of the fixed block 516, the... When the elastic telescopic rod 514 is compressed, the trigger block 515 moves away from the push block 518, causing the top of the push block 518 to separate from the bottom of the trigger block 515. Under the tension of the return spring 512, the lifting platform 510 and the sealing shaft 507 both move downward. The lifting platform 510 moves along the guide rail 520 to the positioning block 521 and stops. At this time, the sealing head 508 disengages from the exhaust port 506, allowing the gas in the tank assembly 1 to be discharged from the cavity formed between the sealing shaft 507 and the sliding sleeve 505. As a result, the gas pressure in the fermenter decreases, and the sensing piston 502 and the drive rod 503 move downward. When the inclined surface at the bottom of the push block 518 contacts the inclined surface at the top of the trigger block 515, the elastic telescopic rod 514 is compressed, and the push block 518 can return to below the trigger block 515.

[0043] The movement of the threaded block 519 is driven by the threaded structure on the threaded rod 523 to rotate. When the lifting plate 517 and the threaded block 519 move downward, the threaded rod 523 drives the one-way ratchet 524 to rotate. The one-way ratchet 524 drives the driven ratchet 525 and the driving synchronous wheel 526 to rotate. Under the transmission of the synchronous belt 6, the rotating rod 320 and the worm gear 321 are driven to rotate, which in turn drives the worm wheel 313 and the turntable 314 to rotate. The turntable 314 drives the slider 316 to slide in the slide groove 318 through the eccentric column 315. At the same time, the lifting frame 317 can move up or down. Under the deceleration effect of the worm gear 321 and the worm wheel 313, the threaded block 519 moves down and drives the worm wheel 313 to rotate 180 degrees each time.

[0044] During fermentation, the drive motor 311 is periodically activated to stir the fermentation tank. The output of the drive motor 311 drives the main shaft 310 and the drive bevel gear 309 to rotate. The drive bevel gear 309 drives the second bevel gear 307 and the first bevel gear 306 to rotate in opposite directions. The movement of the lifting frame 317 drives the reversing plate 304 and the spline 303 to move along the spline 302, so that the spline 303 can drive the first bevel gear 306 and the second bevel gear 307 to rotate respectively. When the spline 303 is engaged in the keyway 308 of the first bevel gear 306, the rotation of the first bevel gear 306 is transmitted through the spline. The transmission of 303 and spline 302 drives the stirring shaft 301 to rotate, thereby driving the stirring blades in the tank assembly 1 to stir the fermentation raw materials. When the spline 303 is engaged in the keyway 308 of the second bevel gear 307, the rotation of the second bevel gear 307 drives the stirring shaft 301 to rotate through the transmission of the spline 303 and spline 302, so that the stirring shaft 301 can obtain different directions of rotation. After a pressure release, it can change the direction of rotation of the stirring shaft 301 by itself, breaking the regularity of stirring of the fermentation raw materials in the tank assembly 1 and improving the uniformity of nutrient distribution in the raw materials and microbial culture medium.
