DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In order to adjust the height-to-diameter ratio of the fermenter, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a tank body, a stirring assembly, a support frame 1 and a lifting mechanism. The tank body includes an upper part 2, a middle part 3 and a lower part 4. The support frame 1 is arranged on the lower surface of the lower part 4. The upper part 2, the middle part 3 and the lower part 4 are connected by a flange fastening ring 5. The lifting mechanism is used to lift the upper part 2 of the tank body to achieve height adjustment of the tank body. When the height of the fermentation tank needs to be adjusted, the lifting plate 9 is driven by the telescopic air pump 10. As the roller 8 slides in the slide groove 7, the lifting plate 9 moves upward. The upper part 2 of the tank body is driven to move with it, and before the upper part 2 of the tank body moves, the flange fastening ring 5 is screwed to separate the lower part 4 of the tank body from the middle part 3 of the tank body. After the upper part 2 of the tank body moves, the middle part 3 of the tank body is disassembled, and the lifting plate 9 is driven by the telescopic air pump 10 again to directly connect the upper part 2 of the tank body with the lower part 4 of the tank body, thereby completing the change of the overall height of the fermentation tank. The overall structure is simple and easy to use. The height-to-diameter ratio of the same fermentation tank can be adjusted, which reduces the cost of early test investment, and the diameter-to-height ratio is adjusted entirely by automatic control.

[0020] In order to facilitate the installation of the tank upper part 2 on the tank lower part 4, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lifting mechanism includes a vertical plate 6 arranged on one side of the tank body, and the vertical plate 6 is provided with a slide groove 7 toward one side of the tank body, and a roller 8 is arranged in the slide groove 7, and a lifting plate 9 is connected to the roller 8 through a connecting plate. When the telescopic air pump 10 drives the lifting plate 9 to rise or fall, the roller 8 slides in the slide groove 7 to support the movement of the upper part 2 of the tank body and improve the stability of the upper part 2 of the tank body during movement. The lifting plate 9 is connected to the upper part 2 of the tank body at one end away from the roller 8. A telescopic air pump 10 is arranged between the vertical plate 6 and the tank body, and the power output end of the telescopic air pump 10 is connected to the lower surface of the lifting plate 9. The telescopic air pump 10 drives the lifting plate 9 to move, thereby driving the upper part 2 of the tank body to rise or fall. The tank body is provided with a stirring assembly, which includes a motor 11 provided at the upper part 2 of the tank body, a first stirring rod 12 connected to the power output end of the motor 11, the first stirring rod 12 is provided in the tank body, and the first stirring rod 12 is provided with a second stirring rod 13 and a third stirring rod 14 in sequence downward, and the material in the tank body can be stirred by the first stirring rod 12, the second stirring rod 13 and the third stirring rod 14. The first stirring rod 12, the second stirring rod 13 and the third stirring rod 14 are detachably connected by a connecting ring 15. When the upper part 2 of the tank body moves upward, the middle part 3 of the tank body is driven to move, at which time the middle part 3 of the tank body is separated from the lower part 4 of the tank body, and the second stirring rod 13 and the third stirring rod 14 are exposed, and the second stirring rod 13 and the third stirring rod 14 are disassembled through the connecting ring 15, so that after the middle part 3 of the tank body is removed, the upper part 2 of the tank body is directly installed on the lower part 4 of the tank body through the flange fastening ring 5. Stirring blades 16 are arranged at equal intervals around the outer sides of the first stirring rod 12, the second stirring rod 13 and the third stirring rod 14, and the stirring blades 16 are used to improve the stirring performance of the material.

[0021] During use, first, when the height of the fermentation tank needs to be adjusted, the lifting plate 9 is driven by the telescopic air pump 10. As the roller 8 slides in the slide groove 7, the lifting plate 9 moves upward, driving the upper part 2 of the tank body to move with it. Before the upper part 2 of the tank body moves, the flange fastening ring 5 is screwed to allow the lower part 4 of the tank body to be separated from the middle part 3 of the tank body. After the upper part 2 of the tank body moves, the middle part 3 of the tank body is disassembled. At this time, the second stirring rod 13 and the third stirring rod 14 are disassembled through the connecting ring 15, and the lifting plate 9 is driven by the telescopic air pump 10 again, so that the upper part 2 of the tank body is directly connected to the lower part 4 of the tank body, thereby completing the change of the overall height of the fermentation tank.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
