The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] like Figures 1 to 4 As shown, the utility model is a fermentation tank cooling device, comprising: a tank body 1, a cooling mechanism for cooling the tank body 1; the cooling mechanism comprises: an outer cooling component for cooling the outer side of the tank body 1, and an inner cooling component for cooling the inside of the tank body 1;

[0030] The outer cooling assembly includes: a cooling shell 6 sleeved on the outer edge of the tank body 1 , a cooling water tank 2 for cooling water, and a return water pipe 7 inserted and installed between the cooling shell 6 and the cooling water tank 2 . The internal cooling assembly includes: a circulating pump 3 fixedly mounted on the top of the cooling water tank 2, a water inlet pipe 5 plugged and installed between the circulating pump 3 and the cooling water tank 2, the bottom end of the water inlet pipe 5 extending to the inner cavity of the cooling water tank 2 near the bottom, a mounting shell 8 fixedly mounted on the top of the tank body 1, a rotating pipe 9 rotatably mounted on the side walls of the tank body 1 and the mounting shell 8, a connecting pipe 14 rotatably mounted on the top of the rotating pipe 9, the other end of the connecting pipe 14 is plugged and installed on the top of the circulating pump 3 and a connecting pipe 3 12 rotatably mounted on the bottom of the rotating pipe 9, the other end of the connecting pipe 3 12 passes through the bottom of the tank body 1, and is plugged and installed on the side wall of the cooling shell 6 and fixedly installed on the side wall of the rotating pipe 9, the connecting pipes 10 located at the top and bottom are both connected to the rotating pipe 9, a plurality of connecting pipes 10 are distributed in a circular array on the outer edge of the rotating pipe 9, connecting pipes 2 11 are plugged and installed on the side walls of adjacent connecting pipes 10, and a plurality of connecting pipes 2 11 are staggered from top to bottom.

[0031] When cooling the tank body 1, by starting the circulation pump 3, the circulation pump 3 sucks out the cold water in the cooling water tank 2 through the water inlet pipe 5, and transports it to the rotating pipe 9 through the connecting pipe 1 4. The cold water in the rotating pipe 9 enters the interlocking pipe 10 located at the top. Since the connecting pipe 2 11 is inserted between the adjacent interlocking pipes 10, the cold water flows through the interlocking pipe 10 located at the top to the inner cavity of the interlocking pipe 10 located at the bottom in turn, and then flows into the inner cavity of the rotating pipe 9 through the inner cavity of the interlocking pipe 10 located at the bottom. At this time, since the rotating pipe 9, the interlocking pipe 10, and the connecting pipe 2 11 are all filled with cold water, the inner wall of the tank body 1 can be cooled down.

[0032] At the same time, the cooling water enters the inner cavity of the cooling shell 6 through the connecting pipe 3 12, and then gradually fills the cooling shell 6, and the cooling shell 6 filled with cold water cools the outside of the tank body 1;

[0033] Finally, the water flows back to the cooling water tank 2 through the return pipe 7, completing the cooling cycle.

[0034] The present application can cool not only the outside of the tank body 1 but also the inside of the tank body 1 through the cooling mechanism, so that the cooling effect of the fermentation tank is better, the cooling efficiency is improved, and great convenience is brought to the user. It solves the problem that the existing cooling device can only cool the outside of the tank body 1 or can only cool the inside of the tank body 1 when in use, resulting in unsatisfactory cooling effect, low cooling efficiency, and great inconvenience to the user.

[0035] It is added here that, since the plurality of connecting pipes 11 are arranged in a staggered manner from top to bottom, the cold water can fill the interlocking pipe 10 in sequence from top to bottom, thereby ensuring the cooling effect of the interlocking pipe 10.

[0036] A motor 13 is fixedly mounted on the top of the mounting shell 8 , a driving gear 14 is fixedly mounted on the power output shaft of the motor 13 , a driven gear 15 is meshedly mounted on one side of the driving gear 14 , and the driven gear 15 is fixedly sleeved on the outer edge of the rotating tube 9 .

[0037] When the tank body 1 is cooled, the motor 13 is started, the motor 13 drives the driving gear 14 to rotate, the driving gear 14 drives the driven gear 15 to rotate, the driven gear 15 drives the rotating tube 9 to rotate, the rotating tube 9 drives the interlocking tube 10 and the connecting tube 2 11 to rotate, and the fermentation liquid inside the tank body 1 can be fully stirred by the rotation of the interlocking tube 10 and the connecting tube 2 11, so that the microorganisms are evenly distributed in the fermentation liquid, and the fermentation speed and effect are improved; on the other hand, the fermentation liquid is cooled evenly and fully, and the cooling effect of the fermentation liquid is further improved.

[0038] Working principle: When in use, by starting the circulation pump 3, the circulation pump 3 sucks out the cold water in the cooling water tank 2 through the water inlet pipe 5, and transports it to the rotating pipe 9 through the connecting pipe 1 4. The cold water in the rotating pipe 9 enters the interlocking pipe 10 located at the top. Since the connecting pipe 2 11 is inserted between the adjacent interlocking pipes 10, the cold water flows through the interlocking pipe 10 located at the top to the inner cavity of the interlocking pipe 10 located at the bottom in turn, and then flows into the inner cavity of the rotating pipe 9 through the inner cavity of the interlocking pipe 10 located at the bottom. At this time, since the rotating pipe 9, the interlocking pipe 10, and the connecting pipe 2 11 are all full of cold water, the inner wall of the tank body 1 can be cooled; at the same time, the cooling enters the inner cavity of the cooling shell 6 through the connecting pipe 3 12, and then gradually fills the cooling shell 6. The cooling shell 6 filled with cold water cools the outside of the tank body 1; finally, the water flows back to the cooling water tank 2 through the return pipe 7 to complete the cooling cycle.
