Description

Technical Field

[0001] The utility model relates to the technical field of bioengineering equipment, in particular to a ventilation volume control device for microbial fermented feed. Background Technique

[0002] Fermentation tanks are usually used in the fermentation of microbial feed. Since gases are usually generated during the fermentation of microbial feed, a ventilation volume control device is usually installed on the fermentation tank to prevent the gas from expanding excessively and causing dangers such as deformation or explosion of the fermentation tank. At the same time, it is necessary to ensure that there is a certain amount of reaction gas in the fermentation tank to promote the reaction.

[0003] A stirring device is usually installed on the fermentation tank to stir the fermented feed. Since the fermented feed contains moisture, the motor cannot be in direct contact with the fermented feed. The stirring motor is usually installed outside the fermentation tank body, and the motor shaft penetrates through the fermentation tank body. This may cause problems such as bacterial contamination due to insufficient mechanical sealing. Moreover, bubbles may be generated during the fermentation of microbial feed, thereby affecting the fermentation process. However, traditional fermentation tanks generally do not have a defoaming function. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , a ventilation volume control device for microbial fermentation feed, including a base 1. A motor 101 is fixedly installed at the bottom of the inner wall of the base 1. The top end of the movable shaft of the motor 101 is fixedly installed with a magnetic chuck 102. A fermentation tank 103 is fixedly installed at the top end of the base 1. The fermentation tank 103 is made of glass. A stirring and defoaming device 2 is movably arranged in the fermentation tank 103. While stirring the microbial fermentation feed in the fermentation tank 103, the stirring and defoaming device 2 can also eliminate the foam on the surface of the microbial fermentation feed. An exhaust valve 3 and an intake valve 4 are fixedly installed at the top end of the base 1. The intake valve 4 is located on one side of the exhaust valve 3. When the air pressure in the fermentation tank 103 is too high, the exhaust valve 3 will automatically open, and the gas in the fermentation tank 103 will be automatically discharged. When it is necessary to inject gas into the fermentation tank 103, it can be injected through the intake valve 4.

[0021] Specifically, the stirring and defoaming device 2 includes a rotating shaft 201 made of metal. The rotating shaft 201 is movably arranged in the fermentation tank 103. A propeller blade 202 is fixedly installed on the outer wall of the rotating shaft 201. A through groove is formed in the center of the rotating shaft 201. The rotating shaft 201 is movably connected to a foam board 203 through the through groove. The foam board 203 can slide up and down in the through groove in the center of the rotating shaft 201. An anti-foaming rake 204 is fixedly installed on the outer wall of the foam board 203. Spikes are fixedly installed at the bottom of the anti-foaming rake 204. The movable shaft of the motor 101 rotates to drive the magnetic chuck 102 to rotate. The magnetic chuck 102 rotates to drive the rotating shaft 201 to rotate. The rotating shaft 201 rotates to drive the foam board 203 to rotate. The foam board 203 rotates to drive the anti-foaming rake 204 to rotate. The anti-foaming rake 204 rotates to break the foam on the surface of the microbial fermented feed.

[0022] Specifically, the exhaust valve 3 includes an exhaust port 301 fixedly installed at the top of the fermentation tank 103. A groove is formed at the top of the exhaust port 301. A rubber strip is fixedly installed in the groove to increase the sealing performance. An exhaust cover 302 is movably connected in the groove. A support rod a 303 is fixedly installed on the inner wall of the exhaust port 301. A sleeve a 304 and a spring a 305 are fixedly installed at the top of the support rod a 303. The sleeve a 304 is located in the center of the spring a 305. A movable column a 306 is movably connected in the sleeve a 304. By setting the sleeve a 304 and the movable column a 306, the exhaust cover 302 can only move linearly up and down. The top of the movable column a 306 is fixedly connected to the bottom of the exhaust cover 302. When the air pressure in the fermentation tank 103 is too high, the air pressure will push the exhaust cover 302 upward, causing the exhaust cover 302 to gradually disengage from the groove at the top of the exhaust port 301. When the exhaust cover 302 completely disengages from the groove at the top of the exhaust port 301, the gas overflows. When the air pressure in the fermentation tank 103 returns to the normal level, the spring a 305 pulls the exhaust cover 302 to engage in the groove at the top of the exhaust port 301.

[0023] Specifically, the intake valve 4 includes an intake port 401 fixedly installed at the top of the fermentation tank 103. A support rod b 402 is fixedly installed on the inner wall of the intake port 401. A sleeve b 403 and a spring b 404 are fixedly installed at the bottom of the support rod b 402. The sleeve b 403 is located in the center of the spring b 404. A movable column b 405 is movably connected to the inner wall of the sleeve b 403. By setting the sleeve b 403 and the movable column b 405, the intake cover 406 can only move linearly up and down. The bottom of the movable column b 405 is fixedly installed with an intake cover 406. An intake bayonet 407 and a limiting ring 408 are fixedly installed on the inner wall of the intake port 401. The limiting ring 408 is located at the bottom of the intake bayonet 407. The intake bayonet 407 and the intake cover 406 are mutually engaged. By setting the limiting ring 408, it is possible to prevent the movable column b 405 from moving downward excessively and affecting the rotation of the anti-foaming rake 204.

[0024] Specifically, an air compressor 104 is provided on one side of the base 1. A control panel 105 is fixedly installed on the air compressor 104. The air outlet of the control panel 105 is fixedly connected to an air delivery pipe 106. The air delivery pipe 106 is movably connected to the exhaust valve 3 or the intake valve 4. When it is necessary to inject reaction gas into the fermentation tank 103, the air delivery pipe 106 is sleeved on the intake port 401, the air compressor 104 is started, and the intake air volume is controlled through the control panel 105. The gas squeezes the intake cover 406 to move downward, and the intake cover 406 gradually disengages from the intake bayonet 407. When the intake cover 406 completely disengages from the intake bayonet 407, the reaction gas enters the fermentation tank 103. When the gas injection is completed, the spring b404 pulls the intake cover 406 to engage in the intake bayonet 407 to prevent gas leakage.

[0025] Specifically, a water storage tank 107 is fixedly installed at the top of the fermentation tank 103. The top of the fermentation tank 103 is connected through a feeding port 108. A movable cover 109 is movably connected to the feeding port 108. A handle is fixedly installed at the top of the movable cover 109. Microbial fermentation feed can be injected into the fermentation tank 103 through the feeding port 108, and then a certain amount of clear water is injected into the water storage tank 107. Finally, the movable cover 109 is covered. The clear water and the movable cover 109 form a sealed space in the fermentation tank 103. When it is necessary to inject reaction gas into the fermentation tank 103, the air delivery pipe 106 is sleeved on the intake port 401, the air compressor 104 is started, and the intake air volume is controlled through the control panel 105. The gas squeezes the intake cover 406 to move downward, and the intake cover 406 gradually disengages from the intake bayonet 407. When the intake cover 406 completely disengages from the intake bayonet 407, the reaction gas enters the fermentation tank 103. When the gas injection is completed, the spring b404 pulls the intake cover 406 to engage in the intake bayonet 407 to prevent gas leakage.

[0026] Working principle of the utility model: When in use, microbial fermentation feed can be injected into the fermentation tank 103 through the feeding port 108, and then a certain amount of clear water is injected into the water storage tank 107. Finally, the movable cover 109 is covered. The clear water and the movable cover 109 form a sealed space in the fermentation tank 103. The motor 101 is started. The movable shaft of the motor 101 rotates to drive the magnetic chuck 102 to rotate. The rotation of the magnetic chuck 102 drives the rotation of the rotating shaft 201. The rotation of the rotating shaft 201 drives the rotation of the foam board 203 and the propeller blade 202. The propeller blade 202 stirs the microbial fermentation feed. The rotation of the foam board 203 drives the rotation of the defoaming rake 204. The rotation of the defoaming rake 204 breaks the foam on the surface of the microbial fermentation feed by external force. When the air pressure in the fermentation tank 103 is too high, the air pressure will push the exhaust cover 302 to move upward, causing the exhaust cover 302 to gradually disengage from the groove at the top of the exhaust port 301. When the exhaust cover 302 completely disengages from the groove at the top of the exhaust port 301, the gas overflows. When the air pressure in the fermentation tank 103 returns to the normal level, the spring a305 pulls the exhaust cover 302 to engage in the groove at the top of the exhaust port 301.
