[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Please see Figures 1-3As shown, this embodiment provides an auxiliary inoculation sterilization cover for a microbial fermenter, including a base 1, a fermenter body 2 rotatably mounted on the top of the base 1, a drive motor for driving the fermenter body 2 to rotate mounted on the base 1, a feed pipe 3 fixedly connected to the top of the outer peripheral wall of the fermenter body 2, a discharge pipe 4 fixedly connected to the bottom of the outer peripheral wall of the fermenter body 2, valves installed on both the feed pipe 3 and the discharge pipe 4, a support frame 5 fixedly mounted on the top of the base 1, heating plates 6 fixedly mounted on both sides of the support frame 5 at positions corresponding to the fermenter body 2, the top plate of the fermenter body 2 being made of transparent material, a sterilization cover 7 fixedly mounted on the top of the fermenter body 2, a door 8 hinged to one side of the outer peripheral wall of the sterilization cover 7, and an ultraviolet sterilization lamp 9 fixedly mounted on the inner peripheral wall of the sterilization cover 7;

[0021] Microorganisms are introduced into the fermentation body through the feed pipe 3, and microorganisms can be discharged from the fermentation tank body 2 through the discharge pipe 4. The heating plate 6 generates heat and rotates the fermentation tank body 2, which enables the heating plate 6 to heat the fermentation tank body 2 evenly. The ultraviolet sterilization lamp 9 inside the sterilization hood 7 can be replaced or repaired by opening the box door 8.

[0022] A collection box 10 is rotatably installed through the top of the fermenter body 2. The collection box 10 is made of transparent material. Two mounting cylinders 11 are threaded through the bottom plate of the collection box 10. An annular scraper 12 is fixedly installed on the inner circumferential wall of the mounting cylinder 11. The annular scraper 12 is made of rubber material. A stirring rod 13 is slidably installed through the annular scraper 12. A connecting plate 14 is fixedly installed at the top of the two stirring rods 13. A rotating cylinder 15 is rotatably installed at the center of the top of the sterilization hood 7. A spline rod 16 is slidably installed through the inner circumferential wall of the rotating cylinder 15. A lifting plate 17 is fixedly installed at the top of the spline rod 16. An electric push rod that drives the lifting plate 17 to move up and down is installed on the support frame 5.

[0023] The lifting plate 17 drives the spline rod 16 to move vertically up and down. This vertical movement of the spline rod 16, via the connecting plate 14, causes the two stirring rods 13 to move simultaneously up and down. When the two stirring rods 13 move upwards simultaneously, they are scraped downwards by the annular scraper 12 within the two mounting cylinders 11, scraping the microorganisms adhering to the outer wall of the stirring rods 13 into the fermenter body 2. Then, the stirring rods 13 enter the sterilization hood 7, where they are sterilized by the ultraviolet sterilization lamp 9. Since both the fermenter body 2 and the collection box 10 are made of transparent material, the ultraviolet sterilization lamp 9 can also sterilize the microorganisms within the fermenter body 2. When the stirring rods 13 move downwards... When in motion, the stirring rod 13 is scraped from bottom to top by the annular scraper 12, thereby scraping away any dust that may be adhering to the outer surface of the sterilized stirring rod 13 into the collection box 10, and then being introduced into the fermentation tank body 2. When the fermentation tank body 2 drives the sterilization hood 7 to rotate synchronously, the spline rod 16 is in a state of relative rotation with the sterilization hood 7 through the rotating cylinder 15. Therefore, under the action of the spline rod 16, the stirring rod 13 is in a state of relative rotation with the fermentation tank body 2. Thus, the stirring rod 13 will stir the microorganisms in the fermentation tank body 2 to promote uniform heating of the microorganisms. Opening the door 8 allows for cleaning of the top of the collection box 10, and the installation cylinder 11 can be rotated out from the top of the fermentation tank body 2 for replacement and maintenance.

[0024] In use, this invention first introduces microorganisms into the fermenter body 2 through the feed pipe 3. Then, the heating plate 6 is turned on to heat the outer wall of the fermenter body 2. Next, the ultraviolet sterilization lamp 9 is turned on, and its light shines through the top plate of the fermenter body 2 to sterilize the microorganisms. The fermenter body 2 is then rotated to ensure even heating. Simultaneously, the stirring rod 13, constrained by the spline rod 16, rotates relative to the fermenter body 2, thus stirring the microorganisms and ensuring uniform heating and irradiation by the ultraviolet sterilization lamp 9. After fermentation is complete, the discharge pipe 4 is opened to collect the fermented microorganisms, and then the process is repeated. The lowering plate 17 drives the spline rod 16 upward until both stirring rods 13 are completely inside the sterilization hood 7. During this process, the outer peripheral wall of the stirring rod 13 is subjected to the action of the annular scraper 12 from top to bottom to scrape the microorganisms adhering to the stirring rod 13 into the inner cavity of the fermentation tank body 2. The stirring rod 13 is sterilized by ultraviolet germicidal lamp in the sterilization hood 7. Then, when the next batch of microorganisms needs to be fermented, the lowering plate 17 drives the spline rod 16 downward again until both stirring rods 13 are completely inside the fermentation tank body 2. During this process, the outer peripheral wall of the stirring rod 13 is subjected to the action of the annular scraper 12 from bottom to top to scrape the dust adhering to the stirring rod 13 into the collection box 10 to keep the outer peripheral wall of the stirring rod 13 clean, so as not to contaminate the next batch of microorganisms during stirring.

[0025] When the ultraviolet lamp malfunctions or the annular scraper 12 is worn, the door 8 can be opened to directly replace or repair the ultraviolet lamp. Then, the mounting cylinder 11 can be rotated to remove it from the top of the fermenter body 2, making it convenient to repair and replace the annular scraper 12 inside the mounting cylinder 11.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
