[0003] Application No. 202322247812.3 discloses a fermenter for biotechnology, which is equipped with a motor, a rotating rod and a concave cleaning blade. When it is necessary to clean the debris that is blocked on the outside of the filter barrel, the motor is started to drive the rotating rod to rotate. When the motor rotates, it drives the concave cleaning blade at the bottom of the rotating rod to rotate, and the concave cleaning blade cleans the outside of the filter barrel.

[0004] When the stirring blades of the above-mentioned application stir the organisms and fermentation agents, it is difficult for the organisms and fermentation agents to mix evenly, and the substances tend to settle at the bottom. At the same time, the filter can directly filter the organisms and fermentation liquid before they have fully fermented, which will affect the fermentation effect. Utility Model Content

[0023] 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.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a fermenter for biotechnology, including a fermentation tank body 1, a fermentation chamber 2 inside the fermentation tank body 1, a filter groove 3 inside the fermentation tank body 1 at the bottom of the fermentation chamber 2, a discharge port 4 inside the fermentation tank body 1 between the fermentation chamber 2 and the filter groove 3, a feed pipe 25 connected inside the fermentation tank body 1 at the top of the fermentation chamber 2 for easy insertion of fermentation raw materials into the fermentation chamber 2, a stirring shaft 5 rotatably connected inside the fermentation chamber 2, stirring blades 6 installed on both sides of the stirring shaft 5, a motor 22 installed on the top of the fermentation tank body 1, the output end of the motor 22 connected to the stirring shaft 5, driving the stirring shaft 5 to rotate, so that the stirring blades 6 can stir the biological materials and... The fermentation agent is stirred to accelerate fermentation. A scraper frame 28 is connected to the outer wall of the stirring shaft 5 and to one side of the stirring blade 6. As the stirring shaft 5 rotates, it facilitates the scraping off of substances adhering to the inner wall of the fermentation chamber 2, accelerating the discharge of nutrient solution. Multiple flaps 7 are connected to the outer side of the stirring blade 6. A groove 11 is formed inside the stirring shaft 5, and a first gear 12 is rotatably connected inside the groove 11. An internal gear ring 13 is installed at the top of the fermentation chamber 2 and outside the stirring shaft 5. The first gear 12 meshes with the internal gear ring 13, so that when the stirring shaft 5 rotates, the first gear 12 rotates under the action of meshing with the internal gear ring 13. A limiting groove 8 is formed inside the stirring shaft 5 and at the bottom of the groove 11. A first bevel gear 9 and a second bevel gear 9 are rotatably connected inside the limiting groove 8. Gear 10 meshes with the first bevel gear 9 and the second bevel gear 10. The second bevel gear 10 is connected to two stirring blades 6, and the first bevel gear 9 is connected to the first gear 12, so that the two stirring blades 6 and the first gear 12 drive each other. As the first gear 12 rotates, it drives the stirring blades 6 and the flap 7 to rotate, turning the fermentation liquid up and down to make it more evenly mixed. A chute 14 is opened inside the biological fermentation tank 1 and on one side of the filter tank 3. A slider 15 is slidably connected inside the chute 14. A sealing plate 16 is connected to one side of the slider 15 and inside the feed port 4. A filter screen 18 is installed inside the filter tank 3 to facilitate the filtration of the fermentation liquid. An electric push rod 17 is installed inside the filter tank 3 and at the bottom of the filter screen 18. The output end of the push rod 17 is connected to a unclog plate 19. Multiple unclogging teeth 20 are installed on the top of the unclog plate 19. A support rod 21 is connected to one side of the unclog plate 19. One end of the support rod 21 passes through the slide groove 14 and connects to the slider 15. Simultaneously, as the electric push rod 17 pushes the unclog plate 19 up and down, the sealing plate 16, under the action of the support rod 21, enters the discharge port 4, sealing the discharge port 4 or being pulled out from the discharge port 4, opening the discharge port 4, and controlling the discharge of fermentation liquid from the filter tank 3. The unclogging teeth 20 on the unclog plate 19 then pass through the filter screen 18 to unclog it. A replenishment box 23 is installed on the top of the biological fermentation tank 1, located to the side of the motor 22. A drain pipe 24 is connected to the bottom of the replenishment box 23, with one end of the drain pipe 24 extending into the fermentation chamber 2.A solenoid valve is installed inside the drain pipe 24. Nutrient solution from the replenishment box 23 is introduced into the fermentation chamber 2 through the drain pipe 24. This works in conjunction with the feed inlet 4 for feeding and replenishment, facilitating control of the concentration of inhibitory substrates. An inlet pipe 26 is connected to the top of the replenishment box 23. A controller 29 is installed on the outer wall of the bio-fermentation tank 1. The controller 29 is electrically connected to the electric push rod 17, the solenoid valve, and the motor 22. A discharge pipe 27 is connected to one side of the bio-fermentation tank 1 near the filter tank 3, facilitating the discharge of fermentation liquid from the filter tank 3. Valves are installed inside the discharge pipe 27, feed pipe 25, and inlet pipe 26.

[0025] In summary, this biotechnology fermenter, during use, feeds the organisms and fermentation agent into the fermentation chamber 2 inside the fermentation tank 1 through the feed pipe 25. The motor 22 drives the stirring shaft 5 to rotate, and the stirring blades 6 on the stirring shaft 5 stir the organisms and fermentation agent, assisting fermentation. Since the first gear 12 inside the stirring shaft 5 meshes with the internal gear ring 13 on the fermentation chamber 2, the first gear 12 rotates as the stirring shaft 5 rotates. Similarly, the first bevel gear 9 meshes with the second bevel gear 10, which is connected to the first gear 12 and the stirring blades 6 respectively. The second bevel gear 10 drives the first gear 12, causing the two stirring blades 6 to rotate. The flaps 7 on the two stirring blades 6 rotate accordingly, tumbling the fermentation liquid up and down. After fermentation for a period of time and the production of new substances, the electric push rod 17 in the filter tank 3 drives the unblocking plate 19 to move down. Through the connection between the support rod 21 on one side of the unblocking plate 19 and the slider 15 in the slide 14, and the connection between the slider 15 and the sealing plate 16 in the discharge port 4, the sealing plate 16 moves down and is pulled out from the discharge port 4, opening the discharge port 4 and discharging part of the fermentation liquid in the fermentation chamber 2 into the filter tank 3. After being filtered by the filter screen 18, the electric push rod 17 pushes the unblocking plate 19 and the sealing plate 16 to reset, so that the sealing plate 16 blocks the discharge port 4 again. Multiple unblocking teeth 20 on the unblocking plate 19 pass through the filter holes of the filter screen 18 to unblock it. At this time, the solenoid valve in the drain pipe 24 is opened to introduce the nutrient solution in the replenishment box 23 into the fermentation chamber 2 for replenishment.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
