Description

Technical Field

[0001] This utility model belongs to the field of microbial fermentation tank technology, specifically relating to a microbial fermentation tank with defoaming function. Background Technology

[0002] A microbial fermenter is a device used for the deep liquid culture of microorganisms, possessing the functions of sterilization and controlled fermentation conditions. It is an indispensable core piece of equipment in the microbial fermentation process and is widely used in the fermentation of enzymes, yeasts, antibiotics, amino acids, vitamins, and other products.

[0003] During the microbial fermentation process in a microbial fermenter, bubbles are generated. The presence of bubbles not only affects the fermentation efficiency but also the fermentation environment. Therefore, defoaming treatment is required inside the fermenter. However, the existing defoaming method involves adding a defoaming agent to the fermenter. This method is difficult to achieve rapid defoaming and has low defoaming efficiency. Therefore, we propose a microbial fermenter with defoaming function. Utility Model Content

[0004] The purpose of this invention is to provide a microbial fermenter with defoaming function to solve the problem mentioned in the background art that the existing defoaming method of fermenters is to add a defoaming agent into the fermenter, which makes it difficult to quickly defoam after the defoaming agent is added, resulting in low defoaming efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbial fermentation tank with defoaming function, comprising a tank body and a tank lid that are interlocked and connected together, wherein the tank lid is provided with a tossing defoaming mechanism, and the tank body is provided with a plurality of oscillating defoaming mechanisms;

[0006] The defoaming mechanism includes a fixed frame and a second motor fixedly mounted on the surface of the can lid. The first motor is fixedly mounted on the surface of the fixed frame. A threaded rod is rotatably mounted on the inner wall of the fixed frame. The output shaft of the first motor is fixedly connected to the threaded rod. A threaded plate is threadedly mounted on the outer surface of the threaded rod. An inner rotating shaft is rotatably mounted on the threaded plate. An outer rotating cylinder for the inner rotating shaft to pass through is rotatably mounted on the inner rotating shaft. A gear is fixedly mounted on the end of the output shaft of the second motor. A gear is fixedly mounted on the outer surface of the outer rotating cylinder. The gears are meshed and used together. A mounting ring is detachably mounted on the bottom end of the inner rotating shaft. Several bubble scrapers are fixedly mounted on the surface of the mounting ring.

[0007] The vibration defoaming mechanism includes a fixed frame fixedly installed on the outer surface of the tank. A fixed block is fixedly installed on the side of the fixed frame. A motor three is fixedly installed on the side of the fixed block. A disc is eccentrically fixedly installed on the outer surface of the output shaft of the motor three. Several sliding rods are slidably installed on the fixed frame. A sliding plate and a mounting shell are fixedly installed at both ends of the sliding rods, respectively. The sliding plate is arranged in close contact with the disc. A spring one is fixedly installed between the sliding plate and the fixed frame. A spring two is fixedly installed on the inner wall of the mounting shell. A knocking head is fixedly installed at the end of the spring two.

[0008] The above-mentioned scheme utilizes a combination of a toggle defoaming mechanism and a vibration defoaming mechanism. The rotation of the foam scraper rapidly removes foam from the fermentation liquid surface, while the tapping head vibrates the tank, causing air bubbles below the surface to rise rapidly under the force of vibration. This effectively improves defoaming efficiency and prevents prolonged bubble retention that could contaminate the fermentation environment. Furthermore, the use of a threaded rod and threaded plate in conjunction with an outer rotating cylinder and an inner rotating shaft allows for vertical movement of the inner rotating shaft, which in turn moves the foam scraper vertically. This allows for adaptive adjustment based on the fermentation liquid level, enhancing versatility and simplifying operation.

[0009] In the above scheme, it should be noted that motor one, motor two and motor three are all electrically connected to an external power supply.

[0010] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the fixed frame, and a guide groove is provided on the side of the threaded plate to cooperate with the guide bars.

[0011] With the above scheme, when the threaded rod rotates and drives the threaded plate to move, the threaded plate will slide on the surface of the guide bar through the guide groove. The cooperation between the guide bar and the guide groove can ensure the stable movement of the threaded plate and prevent tilting and shaking.

[0012] In a preferred embodiment, a number of limiting strips are fixedly installed on the outer surface of the inner rotating shaft, and a number of limiting grooves are opened on the inner wall of the outer rotating cylinder. The limiting strips and the limiting grooves are used in sliding cooperation.

[0013] By using the above solution, the use of limit strips in conjunction with limit grooves can ensure the stability of the inner rotating shaft's up-and-down movement, and also ensure that the inner rotating shaft rotates synchronously when the outer rotating cylinder rotates.

[0014] In a preferred embodiment, a limiting ring is fixedly installed on the outer surface of the bottom end of the inner rotating shaft, the mounting ring and the limiting ring are fitted together, and a bolt is threaded between the mounting ring and the inner rotating shaft.

[0015] Using the above solution, the limiting ring together achieves a limiting and blocking effect on the mounting ring. When used with bolts, it enables convenient locking between the mounting ring and the inner rotating shaft. The threaded connection has good stability and is not easy to loosen.

[0016] In a preferred embodiment, an alignment strip is fixedly installed on the lower surface of the limiting ring, and an alignment slot is provided on the inner wall of the mounting ring for the alignment strip to be inserted.

[0017] By adopting the above solution, the alignment strip is used in conjunction with the alignment slot, which facilitates the alignment and insertion of the mounting ring and improves the ease of assembly.

[0018] In a preferred embodiment, a limiting ring two is fixedly installed on the outer surface of the striking head, and the limiting ring two is slidably attached to the inner wall of the mounting shell.

[0019] By adopting the above solution, the setting of the second limiting ring can prevent the striking head from detaching from the mounting shell during movement, thus achieving a good limiting and protection effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This microbial fermenter with defoaming function uses a combination of a tossing defoaming mechanism and a shaking defoaming mechanism. The rotation of the foam scraper enables the rapid scraping and defoaming of foam on the surface of the fermentation liquid, while the tapping head taps the tank body, causing the bubbles below the surface of the fermentation liquid to move upward quickly under the force of vibration. This effectively improves the defoaming efficiency and prevents bubbles from remaining for a long time and polluting the fermentation environment.

[0022] This microbial fermenter with defoaming function uses a threaded rod and threaded plate in conjunction with an outer rotating cylinder and an inner rotating shaft. The rotation of the threaded rod enables the inner rotating shaft to move up and down, which in turn enables the foam scraper to move up and down. This allows for adaptive adjustment based on the fermentation liquid level, improving its versatility and making operation and adjustment convenient. Attached Figure Description

[0030] Please see Figure 1-6 This utility model provides a microbial fermentation tank with defoaming function, including a tank body 1 and a tank cover 2 that are interlocked and connected together. The tank cover 2 is provided with a tossing defoaming mechanism 3, and the tank body 1 is provided with a plurality of oscillating defoaming mechanisms 4.

[0031] The defoaming mechanism 3 includes a fixed frame 5 and a motor 13 fixedly installed on the surface of the can lid 2. A motor 6 is fixedly installed on the surface of the fixed frame 5. A threaded rod 7 is rotatably installed on the inner wall of the fixed frame 5. The output shaft of the motor 6 is fixedly connected to the threaded rod 7. A threaded plate 8 is threadedly installed on the outer surface of the threaded rod 7. An inner rotating shaft 9 is rotatably installed on the threaded plate 8. An outer rotating cylinder 12 for the inner rotating shaft 9 to pass through is rotatably installed on the inner rotating shaft 9. A gear 14 is fixedly installed at the end of the output shaft of the motor 13. A gear 2 15 is fixedly installed on the outer surface of the outer rotating cylinder 12. Gear 14 and gear 2 15 mesh with each other. An installation ring 10 is detachably installed at the bottom end of the inner rotating shaft 9. Several bubble scraping blades 11 are fixedly installed on the surface of the installation ring 10.

[0032] The vibration defoaming mechanism 4 includes a fixed frame 16 fixedly installed on the outer surface of the tank 1. A fixed block 17 is fixedly installed on the side of the fixed frame 16. A motor 18 is fixedly installed on the side of the fixed block 17. A disc 19 is eccentrically fixedly installed on the outer surface of the output shaft of the motor 18. Several sliding rods 20 are slidably installed on the fixed frame 16. A sliding plate 21 and a mounting shell 23 are fixedly installed at both ends of the sliding rods 20, respectively. The sliding plate 21 is closely fitted to the disc 19. A spring 22 is fixedly installed between the sliding plate 21 and the fixed frame 16. A spring 31 is fixedly installed on the inner wall of the mounting shell 23. A striking head 24 is fixedly installed at the end of the spring 31.

[0033] By using a combination of a toggle defoaming mechanism 3 and a vibration defoaming mechanism 4, the foam scraper 11 is rotated to quickly scrape and defoam the foam on the surface of the fermentation liquid. The tapping head 24 taps the tank 1, causing the bubbles below the surface of the fermentation liquid to move upward quickly under the force of vibration, thereby effectively improving the defoaming efficiency and preventing bubbles from remaining for a long time and contaminating the fermentation environment. By using a threaded rod 7 and a threaded plate 8 in conjunction with an outer rotating cylinder 12 and an inner rotating shaft 9, the rotation of the threaded rod 7 can realize the up and down movement of the inner rotating shaft 9, which in turn realizes the up and down movement of the foam scraper 11. This allows for adaptive adjustment according to the height of the fermentation liquid, improving the versatility of use and making operation and adjustment convenient.

[0034] Several guide bars 25 are fixedly installed on the inner wall of the fixed frame 5. The side of the threaded plate 8 is provided with guide grooves that cooperate with the guide bars 25. When the threaded rod 7 rotates to drive the threaded plate 8 to move, the threaded plate 8 will slide on the surface of the guide bars 25 through the guide grooves. The cooperation between the guide bars 25 and the guide grooves can ensure the stable movement of the threaded plate 8 and prevent tilting and shaking.

[0035] Several limiting strips 26 are fixedly installed on the outer surface of the inner rotating shaft 9, and several limiting grooves are opened on the inner wall of the outer rotating cylinder 12. The limiting strips 26 and the limiting grooves are used in sliding cooperation. By using the limiting strips 26 in cooperation with the limiting grooves, it can ensure the stability of the up and down movement of the inner rotating shaft 9, and also ensure that the outer rotating cylinder 12 will drive the inner rotating shaft 9 to rotate synchronously when it rotates.

[0036] A limiting ring 27 is fixedly installed on the outer surface of the bottom end of the inner rotating shaft 9. The mounting ring 10 and the limiting ring 27 are closely fitted together. A bolt 28 is threaded between the mounting ring 10 and the inner rotating shaft 9. The limiting ring 27 acts as a limiting and blocking effect on the mounting ring 10. When used with the bolt 28, the mounting ring 10 and the inner rotating shaft 9 can be easily locked. The threaded connection has good stability and is not easy to loosen.

[0037] Alignment strip 29 is fixedly installed on the lower surface of the limiting ring 27. Alignment slot is provided on the inner wall of the mounting ring 10 for the alignment strip 29 to be inserted. The alignment strip 29 is used in conjunction with the alignment slot to facilitate the alignment and insertion operation of the mounting ring 10 and improve the ease of assembly operation.

[0038] A limiting ring 20 is fixedly installed on the outer surface of the striking head 24. The limiting ring 20 is slidably attached to the inner wall of the mounting shell 23. The setting of the limiting ring 20 can prevent the striking head 24 from detaching from the mounting shell 23 when it moves, and plays a good role in limiting protection.

[0039] During use, remove the tank lid 2 to check if the bubble scraper 11 needs replacement. If replacement is needed, unscrew bolt 28. After unscrewing bolt 28, unlock the mounting ring 10, then remove the bubble scraper 11. Install the new bubble scraper 11 by inserting the mounting ring 10 into the alignment slot and alignment strip 29. After insertion, tighten bolt 28 to complete the installation and locking. Then, add the microbial fermentation material into the tank body 1, close the tank lid 2, and begin microbial fermentation. When bubbles are generated during fermentation, adjust the height of the bubble scraper 11 according to the fermentation liquid level. To adjust, start motor 6. Motor 6 drives the threaded rod 7 to rotate, which in turn drives the threaded plate 8 to move up and down, thereby driving the bubble scraper 11 to move up and down through the inner rotating shaft 9. Once the bubble scraper 11 is in contact with the surface of the fermentation liquid, stop motor 16 and then start motor 2 13 and motor 3 18. Motor 2 13, in conjunction with gear 1 14 and gear 2 15, drives the outer rotating cylinder 12 to rotate. The outer rotating cylinder 12, through the limiting strip 26, drives the inner rotating shaft 9 to rotate the bubble scraper 11. The rotation of the bubble scraper 11 is used to quickly eliminate bubbles on the surface of the fermentation liquid. At the same time, motor 3 18 drives the disc 19 to rotate. The rotation of the disc 19 drives the sliding plate 21 to move the sliding rod 20, which in turn drives the striking head 24 through the mounting shell 23. The striking head 24 is used to strike the tank 1, causing the bubbles below the surface of the fermentation liquid to float upwards to the surface of the fermentation liquid and be defoamed in conjunction with the bubble scraper 11.
