Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermenters, specifically a fermenter that facilitates the adjustment of internal pressure. Background Technology
[0002] A fermenter is an industrial device used for microbial fermentation. Its main function is to provide a sealed environment that allows microorganisms to ferment efficiently. Its working principle involves using mechanical agitation or air distribution devices to mix the materials evenly while simultaneously introducing sterile air to maintain the oxygen needs of the microorganisms. In the early stages of fermentation, as yeast activity increases and carbon dioxide production occurs, the pressure inside the fermenter gradually increases. In the middle stages of fermentation, as the fermentation process stabilizes, the rate of pressure increase slows and fluctuates within a relatively stable range. In the later stages of fermentation, as fermentation nears its end, the metabolic activity of the microorganisms weakens, the amount of gas produced decreases, and the pressure inside the fermenter may begin to gradually decrease.
[0003] However, existing fermenters are completely sealed environments, making it impossible to effectively regulate the pressure inside the tank. Both excessive and insufficient pressure can have a significant negative impact on the fermented material. Therefore, it is necessary to design a pressure regulating mechanism for the fermenter to facilitate the regulation of the pressure inside the tank. Utility Model Content
[0004] The purpose of this invention is to provide a fermenter that facilitates pressure adjustment within the tank, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fermentation tank that facilitates pressure adjustment, comprising: a fermentation tank and a top cover, wherein the fermentation tank and the top cover are directly connected and installed by screws; a pressure adjustment mechanism mounting hole is provided on the surface of the top cover; one end of an adjustment tank is inserted and fixed into the pressure adjustment mechanism mounting hole; a valve plate is slidably connected to the adjustment tank; a gas storage tank is provided at the top of the adjustment tank by threaded connection; and a lower adjustment channel and an upper adjustment channel are provided on the inner wall of the adjustment tank.
[0006] Preferably, the regulating barrel has an annular cylindrical structure, and a lifting plate is fixed on the inner wall of the regulating barrel. The lifting plate has a circular plate structure, and several sets of air holes are opened on the surface of the lifting plate.
[0007] Preferably, one end of a spring is fixed to the bottom of the lifting plate, and the other end of the spring is fixed to the top of the valve plate.
[0008] Preferably, a guide rod is fixed to the bottom end of the hoisting plate. The guide rod has a rectangular rod structure, and a guide hole is opened on the surface of the valve plate. The guide rod is movably inserted into the guide hole.
[0009] Preferably, the lower adjustment channel has a "U" shaped groove structure, and the lower adjustment channel has two openings on the inner ring surface of the adjustment barrel, with the two openings of the lower adjustment channel being distributed vertically.
[0010] Preferably, the upper adjustment channel has an "S" shaped groove structure, and the upper adjustment channel has an opening on the inner ring and outer ring surface of the adjustment barrel, and the openings of the upper adjustment channel on the outer ring and inner ring of the adjustment barrel are distributed vertically.
[0011] Preferably, the height of the opening of the lower adjustment channel in the upper prescription is higher than the height of the opening of the upper adjustment channel in the lower prescription.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention proposes a fermenter for easy pressure adjustment. The gas storage tank is filled with sterile air. Initially, the gas pressure in the fermenter and the gas storage tank is equal and at the optimal pressure for fermentation. At this time, the valve plate simultaneously seals the opening above the lower adjustment channel and the opening below the upper adjustment channel. As fermentation progresses, when the pressure in the fermenter becomes too high, gas from the fermenter enters the regulating tank through the pressure regulating mechanism mounting hole on the top cover surface, pushing the valve plate upwards. As the valve plate moves upwards, the opening at the bottom of the upper adjustment channel opens, and gas from the top cover exits through the upper opening of the upper adjustment channel into the regulating tank. The gas is discharged, thereby reducing the air pressure in the top cover. When the pressure in the fermenter is too low, the air pressure in the gas storage tank is greater than that in the fermenter. At this time, the gas in the gas storage tank enters the regulating tank and pushes the valve plate downward. As the valve plate moves down, the upper opening of the lower regulating channel opens, while the lower opening of the upper regulating channel remains blocked. At this time, the gas in the gas storage tank enters the lower regulating channel through the upper opening and then enters the fermenter through the lower opening, thereby restoring the air pressure in the fermenter to a certain extent and enabling the fermenter to have a pressure regulating function.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: a fermenter for easy pressure adjustment, comprising: a fermenter 1 and a top cover 2, the fermenter 1 and the top cover 2 being directly connected by screws; a pressure adjustment mechanism mounting hole 3 is provided on the surface of the top cover 2, one end of an adjustment tank 4 is inserted and fixed in the pressure adjustment mechanism mounting hole 3, a valve plate 7 is slidably connected to the adjustment tank 4, and a gas storage tank 13 is provided at the top of the adjustment tank 4 by a threaded connection; a lower adjustment channel 5 and an upper adjustment channel 6 are provided on the inner wall of the adjustment tank 4; the lower adjustment channel 5 has a "U" shaped groove structure, and two openings are provided on the inner ring surface of the lower adjustment channel 5, which are distributed vertically; the upper adjustment channel 6 has an "S" shaped groove structure, and one opening is provided on the inner and outer ring surfaces of the upper adjustment channel 6, which are distributed vertically; the height of the upper opening of the lower adjustment channel 5 is higher than the height of the lower opening of the upper adjustment channel 6.
[0020] In actual use, the gas storage tank 13 is filled with sterile air. Initially, the gas pressure in the fermenter 1 and the gas storage tank 13 is equal and both are at the most favorable pressure for fermentation. At this time, the valve plate 7 simultaneously seals the opening above the lower regulating channel 5 and the opening below the upper regulating channel 6. As fermentation progresses, when the pressure in the fermenter 1 becomes too high, the gas in the fermenter 1 enters the regulating tank 4 through the pressure regulating mechanism mounting hole 3 on the surface of the top cover 2, pushing the valve plate 7 upward. As the valve plate 7 moves upward, the opening at the bottom of the upper regulating channel 6 opens, and the gas in the top cover 2 is discharged from the regulating tank 4 through the opening at the top of the upper regulating channel 6, thereby allowing the top cover to... The gas pressure in tank 2 is reduced; when the pressure in fermenter 1 is too low, the gas pressure in storage tank 13 is greater than that in fermenter 1. At this time, the gas in storage tank 13 enters regulating tank 4 and pushes valve plate 7 downward. As valve plate 7 moves downward, the upper opening of lower regulating channel 5 opens, while the lower opening of upper regulating channel 6 remains blocked. At this time, the gas in storage tank 13 enters lower regulating channel 5 through the upper opening and then enters fermenter 1 through the lower opening of lower regulating channel 5, thereby restoring the gas pressure in fermenter 1 to a certain extent and enabling fermenter 1 to have a pressure regulating function.
[0021] Example 2: Based on Example 1, in order to achieve the hoisting of valve plate 7, the adjusting barrel 4 has an annular cylindrical structure, and a hoisting plate 8 is fixed on the inner wall of the adjusting barrel 4. The hoisting plate 8 has a circular plate structure, and several sets of air holes 12 are opened on the surface of the hoisting plate 8. One end of the spring 10 is fixed at the bottom end of the hoisting plate 8, and the other end of the spring 10 is fixed at the top end of the valve plate 7. A guide rod 9 is fixed at the bottom end of the hoisting plate 8. The guide rod 9 has a rectangular rod structure, and a guide hole 11 is opened on the surface of the valve plate 7. The guide rod 9 is movably inserted into the guide hole 11.
[0022] A lifting plate 8 is fixed in the regulating tank 4, and a spring 10 is fixed between the valve plate 7 and the lifting plate 8. When the valve plate 7 moves up and down under the guidance of the guide rod 9 and the guide hole 11, the spring 10 can be compressed or stretched, so that the valve plate 7 is suspended below the lifting plate 8 while allowing the valve plate 7 to move up and down within a certain range. At the same time, several sets of air holes 12 are opened on the surface of the lifting plate 8 to allow gas to pass through.
[0023] Example 3: Based on Example 2, in order to prevent the sterile gas in the gas storage tank 13 from being wasted or contaminated, the height of the opening of the lower adjustment channel 5 at the upper position is higher than the height of the opening of the upper adjustment channel 6 at the lower position.
[0024] The opening of the lower regulating channel 5 at the top is higher than the opening of the upper regulating channel 6 at the bottom. When the gas pressure in fermenter 1 is too high, valve plate 7 moves upward, and the gas in fermenter 1 is discharged through the upper regulating channel 6, preventing it from entering the area above valve plate 7 and thus avoiding contamination of the sterile gas in gas storage tank 13. When the gas pressure in fermenter 1 is too low, valve plate 7 moves slightly downward, opening the upper opening of the lower regulating channel 5 while keeping the lower opening of the upper regulating channel 6 blocked, allowing gas from gas storage tank 13 to enter the regulating channel. After passing through the lower regulating channel 5, the gas enters the area below the valve plate 7 through the lower regulating channel 5, and cannot be discharged through the upper regulating channel 6, thus preventing waste. External air will also not enter through the upper regulating channel 6, preventing contamination. At the same time, if the pressure in the fermenter 1 is too low, the gas in the fermenter 1 will not move upward through the lower regulating channel 5. As the pressure in the fermenter 1 and the gas storage tank 13 tends to be balanced, the valve plate 7 gradually returns to its original position, re-sealing the upper opening of the lower regulating channel 5, thus preventing the gas in the fermenter 1 from contaminating the sterile air in the gas storage tank 13.
[0025] In actual use, the gas storage tank 13 is filled with sterile air. Initially, the gas pressure in the fermenter 1 and the gas storage tank 13 is equal and both are at the most favorable pressure for fermentation. At this time, the valve plate 7 simultaneously seals the opening above the lower regulating channel 5 and the opening below the upper regulating channel 6. As fermentation progresses, when the pressure in the fermenter 1 is too high, the gas in the fermenter 1 enters the regulating tank 4 through the pressure regulating mechanism mounting hole 3 on the surface of the top cover 2 and pushes the valve plate 7 upward. As the valve plate 7 moves upward, the opening at the bottom of the upper regulating channel 6 opens, and the gas in the top cover 2 is discharged from the regulating tank 4 through the opening at the top of the upper regulating channel 6, thereby reducing the gas pressure in the top cover 2. When the pressure is too low, the gas pressure in the gas storage tank 13 is greater than that in the fermentation tank 1. At this time, the gas in the gas storage tank 13 enters the regulating tank 4 and pushes the valve plate 7 downward. As the valve plate 7 moves downward, the upper opening of the lower regulating channel 5 opens, while the lower opening of the upper regulating channel 6 remains blocked. At this time, the gas in the gas storage tank 13 enters the lower regulating channel 5 through the upper opening and then enters the fermentation tank 1 through the lower opening, thereby restoring the gas pressure in the fermentation tank 1 to a certain extent, thus enabling the fermentation tank 1 to have a pressure regulating function. A lifting plate 8 is fixed in the regulating tank 4, and a spring 10 is fixed between the valve plate 7 and the lifting plate 8. When the valve plate 7 is in the lower regulating channel 4, the gas pressure in the fermentation tank 1 is restored to a certain extent, thus enabling the fermentation tank 1 to have a pressure regulating function. A lifting plate 8 is fixed in the regulating tank 4, and a spring 10 is fixed between the valve plate 7 and the lifting plate 8. When the guide rod 9 and guide hole 11 move up and down, the spring 10 can be compressed or stretched, thus allowing the valve plate 7 to move up and down within a certain range while suspending the valve plate 7 below the suspending plate 8. Meanwhile, several sets of air holes 12 are provided on the surface of the suspending plate 8 to allow gas to pass through. The opening height of the upper part of the lower regulating channel 5 is higher than the opening height of the lower part of the upper regulating channel 6. When the gas pressure in the fermenter 1 is too high, the valve plate 7 moves upward, and the gas in the fermenter 1 is discharged through the upper regulating channel 6, preventing it from entering the position above the valve plate 7 and thus avoiding contamination of the sterile gas in the gas storage tank 13. When the gas pressure in the fermenter 1 is too low, the valve plate 7 moves slightly downward, allowing the lower regulating channel 5 to move upward. The upper opening of the regulating channel 5 is open, while the lower opening of the regulating channel 6 remains blocked. This allows the gas in the gas storage tank 13 to enter the regulating barrel 4 and then pass through the lower regulating channel 5 into the area below the valve plate 7, preventing it from being discharged through the upper regulating channel 6 and thus avoiding waste. External air also does not enter through the upper regulating channel 6, preventing contamination. Simultaneously, when the pressure in the fermenter 1 is too low, the gas in the fermenter 1 will not move upward through the lower regulating channel 5. As the pressure in the fermenter 1 and the gas storage tank 13 tends to balance, the valve plate 7 gradually returns to its original position, re-blocking the upper opening of the lower regulating channel 5, thus preventing the gas in the fermenter 1 from contaminating the sterile air in the gas storage tank 13.
