Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and specifically relates to a pH adjustment mechanism for a fermentation tank. Background Technique

[0002] Fermentation refers to the process by which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microorganisms themselves, or directly produce metabolites or secondary metabolites. Sometimes, fermentation is also written as fermentation, and its definition varies depending on the usage occasion. Generally speaking, fermentation mostly refers to a certain decomposition process of organisms for organic matter.

[0003] In the process of mechanized production, the fermentation of products or microorganisms is usually carried out in a fermentation tank. A fermentation tank refers to a device used in industry for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plates, with a volume ranging from 1 m³ to hundreds of m³. In design and processing, attention should be paid to strict and reasonable structure, being able to withstand steam sterilization, having a certain operating flexibility, minimizing internal accessories (to avoid dead corners), having strong material and energy transfer performance, and being able to be adjusted to facilitate cleaning, reduce pollution, being suitable for the production of various products, and reducing energy consumption.

[0004] However, when adjusting the internal pH value of a fermentation tank, the adjusting reagent can only be placed at a single position inside the fermentation tank, and then stirring is carried out. The time for the adjusting reagent to diffuse in the fermentation tank is slow and the diffusion is uneven, resulting in a long time and low efficiency for adjusting the internal pH value of the fermentation tank. Therefore, it does not meet the existing requirements. For this reason, we propose a pH adjustment mechanism for a fermentation tank. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pH adjustment mechanism for a fermentation tank, so as to solve the problems raised in the above background technique, that is, when adjusting the internal pH value of a fermentation tank, the adjusting reagent can only be placed at a single position inside the fermentation tank, and then stirring is carried out. The time for the adjusting reagent to diffuse in the fermentation tank is slow and the diffusion is uneven, resulting in a long time and low efficiency for adjusting the internal pH value of the fermentation tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pH adjustment mechanism for a fermenter, comprising a fermenter body, a sealing cap detachably mounted on the top of the fermenter body, and adjusting reagent injection tanks fixedly mounted on both sides of the top of the fermenter body. Two symmetrically positioned booster pumps are detachably mounted inside the fermenter body. A connecting pipe is fixed to the input end of each booster pump, and an output pipe is fixed to the output end of each booster pump. A fixing ring is fixed between the two output pipes. A rotating inner ring is rotatably mounted inside the fixing ring. A rotating flow channel is provided between the fixing ring and the rotating inner ring. The output pipe communicates with the rotating flow channel. A rotating distribution pipe is fixed to the inner side of the rotating inner ring. Multiple nozzles are linearly arrayed on both sides of the rotating distribution pipe, and each nozzle has a solenoid valve inside.

[0007] Preferably, a partition is fixed inside the rotary distribution tube, which divides the inside of the rotary distribution tube into two reagent flow chambers. The two reagent flow chambers are rotationally symmetrical, with one end of the reagent flow chamber being closed and the other end being open and connected to the rotary flow channel.

[0008] Preferably, both ends of the partition are fixed with movable sealing plates, the movable sealing plates are circular and their edges slide in contact with the inner wall of the fixed ring and the inner wall of the rotating inner ring.

[0009] Preferably, the positions of the two movable sealing plates are rotationally symmetrical about the center point of the partition, and there is an inclined angle between the movable sealing plates and the partition.

[0010] Preferably, a sealing plug is installed on the inner side of the top of the regulating reagent injection container, and the sealing plug is T-shaped and made of rubber.

[0011] Preferably, the top end of the connecting tube is bent at a 90-degree arc towards the regulating reagent injection tank and inserted into the inner wall of the fermenter body, and the top end of the connecting tube coincides with the bottom axis of the regulating reagent injection tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves adding the regulating reagent to the regulating reagent injection tank, and starting the booster pump to extract the regulating reagent through the connecting pipe and inject it into the inner side of the rotating flow channel through the output pipe. This causes the regulating reagent to push the moving sealing plate and the rotating distribution pipe to rotate around the axis of the fixed ring. During this process, the regulating reagent enters the rotating distribution pipe from the gap between the partition plate and the end of the rotating distribution pipe, and is sprayed outward through the nozzle. This ensures that the regulating reagent falls evenly inside the fermenter, shortens the diffusion time of the regulating reagent, and improves the efficiency of pH adjustment inside the fermenter.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a pH adjustment mechanism for a fermenter is provided. A sealing cover 2 is detachably installed on the top of the fermenter body 1. Adjustment reagent injection tanks 3 are fixedly installed on both sides of the top of the fermenter body 1. A sealing plug 4 is installed on the inner side of the top of the adjustment reagent injection tank 3. The sealing plug 4 is T-shaped and made of rubber.

[0021] The fermenter body 1 has two symmetrically positioned booster pumps 6 that are detachably installed inside. The input end of the booster pump 6 is fixed with a connecting pipe 5. The top end of the connecting pipe 5 is bent at a 90-degree arc towards the regulating reagent injection tank 3 and inserted into the inner wall of the fermenter body 1. The top end of the connecting pipe 5 is aligned with the bottom axis of the regulating reagent injection tank 3. The top of the regulating reagent injection tank 3 is sealed with a sealing plug 4 to ensure that the inside of the fermenter body 1 remains sealed when no regulating reagent is added.

[0022] An output pipe 7 is fixed to the output end of the booster pump 6. A fixed ring 8 is fixed between the two output pipes 7. A rotating inner ring 9 is rotatably installed on the inner side of the fixed ring 8. A rotating flow channel 14 is provided between the fixed ring 8 and the rotating inner ring 9. The output pipe 7 is connected to the rotating flow channel 14. A rotating distribution pipe 10 is fixed to the inner side of the rotating inner ring 9. Multiple nozzles 11 are linearly arrayed on both sides of the rotating distribution pipe 10. A solenoid valve is provided inside the nozzle 11. The pH adjustment reagent prepared by the external agent is injected into the rotating flow channel 14 through the connecting pipe 5, the booster pump 6, and the output pipe 7 by adjusting the reagent injection tank 3. Then, the adjustment reagent enters the rotating distribution pipe 10 through the rotating flow channel 14 and is sprayed into the fermenter body 1 through the nozzles 11, thereby adjusting the pH value inside the fermenter body 1.

[0023] A partition 12 is fixed inside the rotary distribution tube 10. The partition 12 divides the inside of the rotary distribution tube 10 into two reagent flow chambers. The two reagent flow chambers are rotationally symmetrical, and one end of the reagent flow chamber is closed, while the other end is open and connected to the rotary flow channel 14. This allows the regulating reagent to enter the rotary distribution tube 10 from both ends without interfering with each other. The regulating reagent is then sprayed into the fermenter body 1 through the nozzles 11 on both sides of the rotary distribution tube 10.

[0024] Movable sealing plates 13 are fixed at both ends of the partition 12. The movable sealing plates 13 are circular and their edges slide in contact with the inner wall of the fixed ring 8 and the inner wall of the rotating inner ring 9. The positions of the two movable sealing plates 13 are rotationally symmetrical about the center point of the partition 12. There is an inclined angle between the movable sealing plates 13 and the partition 12. The two movable sealing plates 13 divide the rotating flow channel 14 into two spaces that do not interfere with each other, so that the regulating reagent can only flow in a single direction inside the rotating flow channel 14 and push the movable sealing plates 13. As a result, the rotating distribution tube 10 moves in a circle around the axis of the rotating inner ring 9 under the drive of the movable sealing plates 13, thereby spraying the regulating reagent evenly inside the fermenter body 1.

[0025] Working principle: When the pH value inside the fermenter body 1 changes and needs adjustment, the operator first needs to determine the degree of pH change inside the fermenter body 1. Then, the corresponding amount and concentration of pH adjusting reagent are prepared externally. Next, the sealing plug 4 at the top of the adjusting reagent injection tank 3 is removed, and the adjusting reagent is added into the adjusting reagent injection tank 3 from the top. Then, the power supply of the booster pump 6 is turned on and started. The booster pump 6 draws the pH adjusting reagent from the adjusting reagent injection tank 3 and injects it into the rotating flow channel 14 through the output pipe 7. After entering the rotating flow channel 14, the adjusting reagent fills the space between the two moving sealing plates 13. Simultaneously, the moving sealing plate 13 is pushed to make a unidirectional circular motion around the axis of the fixed ring 8 inside the rotating channel 14. At the same time, the adjusting reagent enters the rotating distribution tube 10 through the gap between the partition plate 12 and the end of the rotating distribution tube 10, and is sprayed into the fermenter body 1 from the nozzle 11. When the moving sealing plate 13 makes a circular motion, the rotating inner ring 9 at the top rotates around the axis of the fixed ring 8, so that the rotating distribution tube 10 rotates freely around the center of the rotating inner ring 9. This allows the nozzle 11 at the top of the rotating distribution tube 10 to spray the adjusting reagent evenly into the fermenter body 1, shortening the diffusion time of the adjusting reagent and improving the efficiency of pH adjustment inside the fermenter.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
