Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the attached Figures 1-5 The aeration type high-efficiency double-tower fermentation tank shown includes a base 1, two tank bodies 2 are supported on the top end of the base 1, a discharge port 3 is provided on one side of the bottom end of each tank body 2, a feed port 4 is provided on the top end of each tank body 2, a stirring mechanism 5 is provided on each tank body 2, the two stirring mechanisms 5 are jointly connected to a fan 7, the air inlet end of the fan 7 is connected to a filter cartridge 8, the filter cartridge 8 is connected to an intake pipe 11, exhaust valves are installed on the top ends of the tank bodies 2, a pressure detector is provided on one side of the exhaust valve, a detachable filter element is provided in the filter cartridge 8, a sealing cover is provided on the feed port 4, a sealing gasket is provided in the sealing cover, a first bracket 9 is supported on the top of each tank body 2, and a second bracket 10 is jointly supported by the two tank bodies 2.

[0024] During specific implementation, setting two tanks 2 can increase the total fermentation capacity and facilitate the simultaneous use of raw materials in different fermentation periods. During the fermentation process, the stirring mechanism 5 can stir the raw materials inside the tank 2 to fully mix the raw materials. During the stirring process, when the fan 7 operates, it can extract external gas. After filtering the external impurities through the filter element in the filter cartridge 8, the gas enters the stirring mechanism 5 and then is dispersed inside the stirring mechanism 5 to aerate the raw materials inside the tank 2, increasing the aeration range. Thereby, the oxygen content in the tank 2 can be increased to facilitate the rapid decomposition of microorganisms into organic matter and improve the fermentation efficiency. During the aeration process, the air pressure detector detects the air pressure inside the tank 2. When the set value is reached, the exhaust valve opens for exhaust to avoid the situation of explosion due to excessive air pressure inside the tank 2, thereby improving the safety of fermentation.

[0025] The stirring mechanism 5 includes a motor 501, a rotating rod 502, a driving gear 503, a stirring cylinder 504, a follower gear 505, and an aeration pipe 506. The motor 501 is installed on the first bracket 9. The output end of the motor 501 is connected to the rotating rod 502. The bottom end of the rotating rod 502 is installed with the driving gear 503. The stirring cylinder 504 is rotatably installed at the top of the tank 2. The top of the stirring cylinder 504 is installed with the follower gear 505. The follower gear 505 and the driving gear 503 are meshed and connected. A plurality of aeration pipes 506 are installed on the stirring cylinder 504, and each aeration pipe 506 is communicated with the inside of the stirring cylinder 504.

[0026] During specific implementation, when the motor 501 operates, the rotating rod 502 rotates, so that the driving gear 503 meshes with the follower gear 505 to rotate, causing the stirring cylinder 504 to rotate, and thus the aeration pipes 506 stir and mix the raw materials, improving the uniformity and mixing efficiency of the raw material mixing. And by rotatably installing the charging pipe 6 at the top of the stirring cylinder 504, during the rotation of the stirring cylinder 504, it can be avoided that the charging pipe 6 rotates along with it, thereby avoiding the torsion of the charging pipe 6, and thus ensuring the stability of gas transmission. And through the aeration of each rotating aeration pipe 506, the aeration range can be increased, further improving the uniformity of oxygen distribution in the raw materials.

[0027] The top of the stirring cylinder 504 is rotatably installed with a charging pipe 6. The top end of the charging pipe 6 is fixedly arranged on the second bracket 10. The exhaust ends of the fans 7 are connected with two air delivery pipes 12. Each air delivery pipe 12 is installed with a solenoid valve 13, and one end of each air delivery pipe 12 is respectively connected with the corresponding charging pipe 6.

[0028] During specific implementation, the operation of the blower 7 enables the filter element to filter the external air. The corresponding air delivery pipe 12 is controlled to open through the solenoid valve 13. Thus, with the cooperation of the two solenoid valves 13, the start and stop of the inflation of different tanks 2 can be controlled, thereby avoiding gas waste when the tanks 2 are not in use. During the aeration process, the tank 2 is in a sealed state, and the incoming gas is filtered by the filter element, thereby improving the cleanliness of the incoming gas and avoiding the influence of external microorganisms on the fermentation of raw materials. In this way, not only can the fermentation efficiency be improved, but also fermentation deterioration can be avoided.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
