[0002] A fermentation tank is a closed container or bioreactor mainly for culturing microbial strains or cells, which can be used for research, analysis and production. The existing microbial fermentation engineering has higher requirements for fermentation tanks, not only requiring hygienic conditions, but also requiring oxygen control and temperature control. For the large-scale cultivation of strains, various growth conditions of microbial strains need to be considered, including temperature, pH value, oxygen, seed age and inoculation amount.

[0003] When the fermentation tank ferments, it is easy to generate heat, which will cause the temperature to be too high. A cooling device needs to be installed to cool down the fermentation tank. Most of the existing cooling devices for fermentation tanks are wound around the outer wall of the fermentation tank and use flowing cooling water for cooling. However, the cooling effect is limited to the position of the installation part, resulting in poor cooling effect. And the cooling water is usually directly discharged after cooling the fermentation tank, reducing the utilization rate of water resources. Summary of the Utility Model

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0022] As Figures 1-4 shown, the present invention provides a technical solution: a cooling device for a fermentation tank, including a cooling tank 1 and a fermentation tank 2. The bottom of the cooling tank 1 is fixedly connected with a bottom column 11. The bottom of the fermentation tank 2 is fixedly connected to the bottom end of the inner wall of the cooling tank 1. The top of the fermentation tank 2 is fixedly connected with a feed pipe 21. The bottom end of the surface of the fermentation tank 2 is fixedly connected with a discharge pipe 22. Both the feed pipe 21 and the discharge pipe 22 penetrate through the inner wall of the cooling tank 1. The bottom of the cooling tank 1 is fixedly connected with a water storage tank 4. The outer wall of the water storage tank 4 is respectively fixedly installed with a water inlet pipe 41 and a water outlet pipe 42 on one side. The outer wall of the water storage tank 4 on the other side is fixedly connected with a connecting block 43. The top of the connecting block 43 is movably installed with a water pump 5. The inner wall of the cooling tank 1 is movably installed with a water guide pipe 12. The water guide pipe 12 is installed around the inside of the cooling tank 1. The surface of the water guide pipe 12 is fixedly installed with a sprinkler head 13. The surface of the water guide pipe 12 is provided with a fixed block 14. One side of the fixed block 14 is fixedly connected with the inner wall of the cooling tank 1. The water pumping end of the water pump 5 is located inside the water storage tank 4. The water outlet end of the water pump 5 is fixedly installed with a connecting pipe 51. The top of the connecting pipe 51 is fixedly connected with the bottom of the water guide pipe 12.

[0023] In this embodiment, cooling water is added into the water storage tank 4 through the water inlet pipe 41. The fermentation tank 2 is located inside the cooling tank 1, and the water guide pipe 12 is wound around the surface of the fermentation tank 2. When the temperature inside the fermentation tank 2 is too high, the water pump 5 is started to pump the cooling water inside the water storage tank 4 into the water guide pipe 12. The cooling water sprays out from each nozzle 13 on the surface of the water guide pipe 12 and evenly sprays onto the outer wall of the fermentation tank 2. Moreover, the cooling water flows downward on the surface of the fermentation tank 2, increasing the contact area between the cooling water and the outer wall of the fermentation tank 2 and making the cooling inside the fermentation tank 2 more uniform. Embodiment

[0024] As Figures 1-4 shown, a ventilation opening 101 is provided on the surface of the cooling tank 1, a drain opening 102 is provided at the bottom of the cooling tank 1, a mounting bracket 3 is fixedly installed at the top end of the cooling tank 1. The inside of the mounting bracket 3 is a hollow structure. The mounting bracket 3 penetrates through the top of the cooling tank 1. A fixing plate 31 is fixedly installed inside the mounting bracket 3. A fan 32 is fixedly installed at the bottom of the fixing plate 31. The input shaft of the fan 32 is connected to a control motor. An opening 401 is provided at the top of the water storage tank 4, and the opening 401 communicates with the drain opening 102.

[0025] In this embodiment, when the cooling water covers the outer wall of the fermentation tank 2, then the control motor is started to drive the fan 32 to rotate, so that the fan 32 blows air into the cooling tank 1, increasing the air flow rate on the surface of the fermentation tank 2, and thus making the evaporation rate of the cooling water faster. Since the cooling water is in an endothermic state during evaporation, the cooling effect on the fermentation tank 2 is improved. The cooling water that is not evaporated on the surface of the fermentation tank 2 flows to the bottom of the cooling tank 1, and the accumulated water drips into the water storage tank 4 through the drain opening 102 to collect and recycle the excess cooling water.

[0026] The working principle of this embodiment: When the temperature inside the fermentation tank 2 is too high and needs to be cooled down, cooling water is added into the water storage tank 4. The water pump 5 is started to pump the cooling water inside the water storage tank 4 into the water guide pipe 12. The cooling water sprays out from each nozzle 13 on the surface of the water guide pipe 12 and evenly sprays onto the outer wall of the fermentation tank 2, increasing the contact area between the cooling water and the outer wall of the fermentation tank 2. Then the control motor is started to drive the fan 32 to rotate, so that the fan 32 blows air into the cooling tank 1, increasing the air flow rate on the surface of the fermentation tank 2, and thus making the evaporation rate of the cooling water faster, improving the cooling effect on the fermentation tank 2. The cooling water that is not evaporated on the surface of the fermentation tank 2 flows to the bottom of the cooling tank 1 and drips into the water storage tank 4 through the drain opening 102 to collect and recycle the excess cooling water, reducing the waste of water resources.
