[0022] Tank 1: A stirring shaft 12 is rotatably connected to its middle section. Liquid bacteria and nutrient solution are added to the interior of tank 1. The middle section of the stirring shaft 12 is fixedly connected to the upper end of the cooling pipe 2 (the cooling pipe 2 runs through the interior of the stirring shaft 12, with its two openings located at the upper end of the stirring shaft 12). The cooling pipe 2 is made of stainless steel. A double-channel rotary joint 3 is located at the upper end of tank 1. The upper end of the cooling pipe 2 is fixedly connected to the lower end of the double-channel rotary joint 3. A water tank 5 and a circulating pump 6 are located on the upper surface of tank 1. The outlet pipe at the rear end of the double-channel rotary joint 3 is connected to the interior of the water tank 5. The upper end of the stirring shaft 12 drives the rotor of the double-channel rotary joint 3 to rotate synchronously. The rotor at the lower end of the double-channel rotary joint 3 and the stator at the upper end rotate relative to each other. To ensure the continuity of the flow channels, the pumping end of the circulating pump 6 is connected to the lower end of the water tank 5. The outlet end of the circulating pump 6 is equipped with a cooling shell 4. The circulating pump 6 pumps the water from the water tank 5 into the cooling shell 4. The upper end of the cooling shell 4 is connected to the inlet pipe at the front end of the double-channel rotary joint 3. The cooled water flows into the cooling pipe 2 through the double-channel rotary joint 3, where it cools the fermentation broth of the bacteria through the wall of the cooling pipe 2. After circulating in the cooling pipe 2, the water is discharged into the water tank 5 through the double-channel rotary joint 3. Thus, the water in the water tank 5 circulates under the action of the circulating pump 6, achieving cooling inside the tank 1. A cooling plate 7 is provided on the left side of the cooling shell 4. The input end of the cooling plate 7 is electrically connected to the output end of the controller 8. The cooling plate 7 absorbs heat from the cooling shell 4. Cooling shell 4 cools the internal flowing water. A heat sink 9, made of aluminum alloy, is located on the hot end of the left side of the cooling element 7. A cooling fan 10 is located on the left side of the heat sink 9. The input of the cooling fan 10 is electrically connected to the output of the controller 8. The cooling fan 10 accelerates the airflow speed on the surface of the heat sink 9, thereby dissipating heat from the cooling element 7. An insulation sleeve 11, made of foamed rubber, is fixedly fitted around the outside of the cooling shell 4 to reduce the influence of external air on the cooling shell 4. A temperature sensor 19 is located at the detection hole at the bottom of the tank body 1. The output of the temperature sensor 19 is electrically connected to the input of the controller 8. A worm gear 13 is located at the upper end of the outer arc surface of the stirring shaft 12. A worm 14 is rotatably connected to the upper surface of the tank body 1. The worm 14 and the worm gear... The tank body 1 is connected by a 13-meshing joint. A motor 15 is mounted on the upper surface of the tank body 1. The output shaft of the motor 15 is fixedly connected to the rear end of the worm gear 14. The input end of the motor 15 is electrically connected to the output end of the controller 8. The motor 15 drives the stirring shaft 12 to rotate via the worm gear 14 and worm wheel 13. The stirring shaft 12 drives the cooling pipe 2 to rotate. The lower end of the cooling pipe 2 is shaped like a horizontal "8," thus agitating the fermentation liquid and ensuring uniform cooling. A guide shell 16 is located at the lower end of the outer arc surface of the tank body 1. A fan 17 is located at the air inlet on the outer arc surface of the tank body 1. Two air outlets 18 are opened on the outer arc surface of the guide shell 16. The outer arc surface of the guide shell 16 is fixedly connected to the right side of the controller 8. The input end of the fan 17 is electrically connected to the output end of the controller 8, and the fan 17 operates.Air is blown into the interior of the guide shell 16 to accelerate the airflow speed on the surface of the tank 1, and then discharged through the air outlet 18, thereby cooling the liquid bacteria through the wall of the tank 1;

[0023] It also includes a controller 8, which is set on the outer arc surface of the tank 1. The input end of the circulating pump 6 is electrically connected to the output end of the controller 8, and the input end of the controller 8 is electrically connected to an external power source. The controller 8 facilitates the automatic control of electrical appliances. The temperature sensor 19 detects the temperature inside the tank 1 and transmits the detection result to the controller 8.

[0024] The working principle of the liquid microbial fermentation tank with cooling device provided by this utility model is as follows: During use, liquid microbial culture and nutrient solution are added to the inside of the tank 1. Temperature sensor 19 detects the temperature inside the tank 1 and transmits the detection result to controller 8. When the internal temperature is high, controller 8 controls the circulation pump 6, cooling element 7, motor 15, and cooling fan 10 to operate. The circulation pump 6 pumps water from the water tank 5 to the inside of the cooling shell 4. The cold end of the cooling element 7 is fixedly connected to the left side of the cooling shell 4. The cooling element 7 absorbs heat from the cooling shell 4, and the cooling shell 4 cools the flowing water inside. The cooled water flows into the cooling pipe 2 through the double-channel rotary joint 3, cools the fermentation liquid of the microbial culture through the wall of the cooling pipe 2, circulates in the cooling pipe 2, and then discharges into the water tank 5 through the double-channel rotary joint 3. The water circulates under the action of the circulating pump 6, which can cool the inside of the tank 1. The motor 15 drives the stirring shaft 12 to rotate through the worm 14 and worm wheel 13. The stirring shaft 12 drives the cooling pipe 2 to rotate. The lower end of the cooling pipe 2 is in a horizontal figure-eight shape, which agitates the fermentation liquid to ensure uniform cooling. The upper end of the stirring shaft 12 drives the rotor of the double-channel rotary joint 3 to rotate synchronously. The rotor at the lower end of the double-channel rotary joint 3 and the stator at the upper end rotate relative to each other, while ensuring the connection of the flow channel. At the same time, the fan 17 works to blow air into the inside of the guide shell 16, which accelerates the air flow speed on the surface of the tank 1. The air is then discharged through the air outlet 18, which cools the liquid bacteria through the wall of the tank 1. The cooling fan 10 accelerates the air flow speed on the surface of the heat sink 9 to dissipate heat from the cooling plate 7.

[0025] It is worth noting that the circulating pump 6, cooling chip 7, controller 8, cooling fan 10, motor 15, and temperature sensor 19 disclosed in the above embodiments can be freely configured according to the actual application scenario.
