Detailed implementation manners
[0020] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text is only used to describe a multi-channel microbial fermentation culture device of the present utility model or several specific implementation manners, and does not strictly limit the specific protection scope claimed by the present utility model. As used herein, the terms up and down and left and right do not limit their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent. The following details the specific features of the multi-channel microbial fermentation culture device:
[0021] Refer to Figures 1-4 , a multi-channel microbial fermentation culture device according to an embodiment of the present utility model includes a tank body 1, a tank cover 7, a motor 9, a fan blade 14, a feeding port 10, a discharging port 3, an air inlet 4, a sight glass 6, a detection hole 11, an air vent 12, and a cooling layer 19. The feeding port 10, the detection hole 11, and the air vent 12 are fixedly installed on the tank cover 7. The discharging port 3 and the air inlet 4 are fixedly installed at the bottom of the tank body 1. The motor 9 is fixed on the tank body 1. The motor shaft of the motor 9 penetrates through the tank body 1 and fixes the rotating shaft 15. The sight glass 6 is fixedly installed on one side of the tank body 1. The cooling layer 19 is fixedly installed on the surface of the tank body 1. An air ventilation component is arranged at the bottom inside the tank body 1. This is a conventional structure of the multi-channel microbial fermentation culture device, and basic microbial fermentation culture is realized through the above structure.
[0022] However, there are still deficiencies in the microbial fermentation culture devices on the market. The existing air ventilation components are basically in the form of single-channel input, which has problems such as uneven gas distribution and low ventilation efficiency. Then, in order to improve this problem, the inventor adopts a multi-channel input form, and the specific structure is: multiple gas transmission channels are arranged at the bottom.
[0023] A gas storage space 20 is fixedly installed at the bottom inside the tank body 1, and is cooperatively fixedly communicated with at least two one-way valve air outlets 16, so that air can be evenly injected into the tank, improving the mixing effect of oxygen and microorganisms.
[0024] In addition, the current stirring shaft and stirring blades are longitudinally arranged in the stirring tank, which accelerates the linear rising process of the bubbles and results in a short dissolved oxygen time. Due to the obstruction of the longitudinal upward force, the upper part of the fermentation broth cannot be fully mixed with the lower part. Therefore, this structure has the defects of uneven stirring and poor oxygen mixing effect. For this reason, the inventor considered making the stirring shaft into a horizontally rotating structure, which can change the linear rising process of the bubbles and drive the circulating flow of the upper and lower liquids, so as to achieve the purpose of uniform stirring and good oxygen mixing effect.
[0025] The horizontally rotating structure includes a rotating block 18 installed on the rotating shaft 15. A pair of fan blades 14 are horizontally rotatably arranged on the rotating block 18. A driving assembly is installed on the rotating block 18 to drive the fan blades 14 to rotate horizontally, and the driving assembly is used to drive the fan blades 14 to rotate horizontally to improve the stirring uniformity and oxygen mixing effect.
[0026] Furthermore, to optimize the stirring effect, the inventor considered making the rotating directions of the two fan blades 14 opposite to each other to form a better eddy current effect in the tank body 1 to optimize the material mixing effect in the tank.
[0027] Specifically, the driving assembly includes a driving bevel gear 22 rotatably installed in the rotating block 18. The driving bevel gear 22 meshes with two driven bevel gears 21 at the same time. Each driven bevel gear 21 is fixed to one of the fan blades 14. When the driving bevel gear 22 is driven to rotate, the two driven bevel gears 21 rotate in opposite directions, driving the two fan blades 14 to rotate in opposite directions.
[0028] In addition, the stirring range of the fan blade 14 is around the fan blade 14, resulting in an unsatisfactory mixing effect in the space far from the fan blade 14.
[0029] Furthermore, considering making the two fan blades 14 move up and down to expand the stirring range, the implementation method is to make the rotating block 18 into a lifting type. Specifically, a threaded hole 26 is opened on the rotating block 18. The rotating shaft 15 penetrates through the threaded hole 26. A threaded rod 25 is arranged on the rotating shaft 15 and is threadedly connected to the threaded hole 26. A second chute 31 is opened on the rotating shaft 15. A second slider 32 is fixed on the driving bevel gear 22. The second slider 32 is slidably arranged in the second chute 31.
[0030] In addition, a pair of first chutes 24 are opened on the side wall of the tank body 1. A first slider 23 is slidably installed in the first chutes 24. One end of the fan blade 14 is rotatably arranged on one of the first sliders 23.
[0031] The way to realize the lifting movement of the fan blade 14 is that when the rotating shaft 15 rotates driven by the motor 9, the whole rotating block 18 moves downward or upward through the cooperation of the threaded hole 26 and the threaded rod 25. After rotating a certain number of revolutions, the motor 9 runs in the reverse direction, thereby driving the rotating block 18 to move in the reverse direction.
[0032] (The specific installation structure diagram of the multi-channel microbial fermentation culture device is not shown, but this part of the content is conventional technology. How the tank body 1 and the tank cover 7 are installed and what connection method is used are all conventional technologies in this field).
[0033] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. They all fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
