Description

Technical Field

[0001] This utility model relates to the field of microbial inoculant fermentation technology, specifically a microbial inoculant fermentation tank. Background Technology

[0002] Microbial inoculants are live bacterial preparations made from fermentation broth containing target microorganisms that have been industrially propagated and then adsorbed using adsorbents. Microbial inoculants have wide applications in agriculture, including increasing crop yields, improving the quality of agricultural products, and enhancing soil nutrients. Currently, fermentation tanks are commonly used for the fermentation of microbial inoculants.

[0003] However, existing microbial inoculant fermenters use a fixed pH sensor inside the tank to monitor the internal pH level and ensure it's suitable for microbial fermentation. Because the fermenter is relatively tall, the pH sensor can only detect pH values ​​in one area, leading to situations where other areas have significantly different pH levels and cannot be detected. This hinders fermentation within the optimal pH range and makes it inconvenient to remove and repair the pH sensor. Therefore, innovative designs based on existing microbial inoculant fermenters are urgently needed to address these issues. Utility Model Content

The outer side of the locking pin 10 is movably nested with the inner side of the horizontal plate 11. The outer side of the locking pin 10 is threadedly installed above the horizontal plate 11. A gasket is nested on the outer side of the locking pin 10. The gasket is located between the horizontal plate 11 and the locking member 12. Tightening plates are provided on both sides of the locking member 12. By rotating the tightening plates, the locking member 12 can be removed from the locking pin 10, thereby allowing the horizontal plate 11 to be removed from the locking pin 10.

[0018] A limiting ring 13 is nested and fixed at the top of the outer side of the threaded column 5. A push rod is fixed on the outer wall of the limiting ring 13. The push rods are distributed at equal angles about the central axis of the limiting ring 13. A rubber sleeve is fixed at the bottom of the limiting ring 13. The bottom of the rubber sleeve is in close contact with the top of the tank 1. The limiting ring 13 can be rotated by the push rod, which facilitates the disassembly between the threaded column 5 and the threaded hole 4, so that the hollow movable plate 7 and the pH sensor 8 can be removed from the inside of the tank 1.

[0019] A rotating shaft 14 is rotatably installed at the top center of the tank 1. An agitator 15 is fixed inside the tank 1 on the outer wall of the rotating shaft 14. The upper end of the rotating shaft 14 is fixedly connected to the bottom output end of the motor 16. The outer wall of the motor 16 is fixed to the top of the tank 1 by bolts. By starting the motor 16, the agitator 15 can be driven to rotate, so that the microorganisms and the culture medium can be mixed together, which is conducive to the fermentation of microorganisms.

[0020] The top of the tank 1 is equipped with a feeding hopper 17, and the top of the feeding hopper 17 is threaded with a sealing cap. The bottom of the tank 1 is equipped with a discharge pipe. Microorganisms and culture medium can be injected into the tank 1 through the feeding hopper 17. The top of one side of the tank 1 is equipped with an exhaust gas discharge pipe, which is connected to an external air purification device for purifying the gas discharged from the tank 1. The air purification device is existing equipment and will not be described in detail again. The top of one side of the tank 1 is also equipped with an air delivery pipe, which is connected to an external sterile air generator for injecting air into the tank 1. The sterile air generator is existing equipment and will not be described in detail again. The acid feed pipe 2, the alkali feed pipe 3, the discharge pipe, the exhaust gas discharge pipe, and the air delivery pipe are all equipped with electromagnetic valves. The electromagnetic valves are electrically connected to the control cabinet.

[0021] Working Principle: When using this microbial inoculant fermenter, firstly, the prepared microorganisms and culture medium are poured into the tank 1 through the feed hopper 17. The sealing cap is then installed on top of the feed hopper 17. Next, the motor 16 is started, driving the rotating shaft 14 and the stirring element 15 to rotate, mixing the microorganisms and culture medium together. Then, the cylinder 9 is activated, causing the horizontal plate 11, the hollow movable plate 7, and the pH sensor 8 on the hollow movable plate 7 to move up and down reciprocally inside the tank 1. The vertical movement distance of the pH sensor 8 is equal to the distance between the pH sensors, allowing the pH sensor 8 to detect the pH of the bacterial solution over a large vertical area inside the tank 1, ensuring... The accuracy of the pH value of the bacterial solution inside tank 1 is ensured, which is beneficial to the fermentation of microorganisms inside tank 1. When the pH sensor 8 detects that the pH value inside tank 1 is not suitable for microbial fermentation, the pH sensor 8 transmits a signal to the external control cabinet. The control cabinet controls the pump on the alkali storage tank or acid storage tank to pump the alkali or acid into the tank 1. When the pH sensor 8 detects that the pH value inside tank 1 is suitable for microbial fermentation, the pH sensor 8 transmits a signal to the external control cabinet. The control cabinet controls the pump on the alkali storage tank or acid storage tank to stop working, thereby ensuring that the pH inside tank 1 is always at a suitable value for microbial fermentation, which is beneficial to microbial fermentation. When the pH sensor 8 needs to be disassembled for maintenance, the locking part 12 is rotated by the screw plate to separate the locking part 12 from the threaded connection of the locking post 10. Then, the limit ring 13 is pushed by the push rod, and the limit ring 13 drives the threaded post 5 to rotate, so that the threaded post 5 is separated from the threaded connection of the threaded hole 4. Then, the hollow movable plate 7 and the pH sensor 8 are pulled out from the inside of the tank 1 through the threaded hole 4, so that the pH sensor 8 can be easily disassembled from the inside of the tank 1 for maintenance.
