Description

Technical Field

[0001] The present invention relates to the technical field related to fermentation tanks, in particular to a multi-layer biological fermentation tank. Background Art

[0002] As a microbial cultivation reactor, the fermentation tank can mix materials evenly and achieve efficient synthesis of target products by providing a controllable physical and chemical environment for microorganisms or cells. Fermentation tanks are very common in current industrial applications, replacing traditional fermentation containers such as culture bottles, sauce jars and wine cellars, greatly improving efficiency and output.

[0003] A multi-layer fermentation tank is a device used in biological fermentation processes. Its design feature is that the tank has a multi-layer structure inside, and the material flows from top to bottom. Each layer undergoes a specific reaction, and the bacteria are propagated in the upper layer, and the easily degradable substrates are quickly consumed. The lower layer is in the main fermentation stage, and the product is synthesized in large quantities. At present, the same stirring structure is used in multi-layer fermentation tanks, but the diffusion of the upper layer bacteria requires sufficient mixing and stirring of the fermented material. When the bacteria diffuse and degrade the substrate in the upper layer, the decomposition products are very likely to leave adhesions on the inner wall of the fermentation tank. During the fermentation process of the lower layer bacteria, the fermentation products cannot be quickly stirred and mixed, because the fermentation products will die due to the force during the high-speed centrifugation process, resulting in contamination of the fermentation liquid, which reduces the purity of the fermentation liquid, and fails to distinguish and mix the fermented materials in different states in the upper and lower layers.

When the cleaning scraper 30 is pushed out and abuts against the inner wall of the fermentation tank body 10, the cleaning scraper 30 can be used to complete the cleaning of the upper layer of the fermentation tank body 10. A pushing component for pushing the scraper is provided inside the stirring drum 20, and the pushing component includes a plurality of components installed on the four sides of the stirring drum 20. The fermentation tank body 10 is provided with a support rod 31 around it, and a barrel 40 for storing baking powder is provided on the top of the fermentation tank body 10. A quantitative component for quantitatively discharging the fermentation tank body 10 is provided at the bottom of the fixed plate 11. The fermentation tank body 10 is provided with a breaking plate 57 for mixing and breaking up the fermented material after fermentation. A rotating cylinder 12 for driving the breaking plate 57 to move is installed at the bottom of the fixed plate 11. A twisting component for driving the breaking plate 57 to twist is provided inside the rotating cylinder 12. The fermentation tank body 10 is provided with a rotating disk 60 for assisting mixing of the fermented material at the top of the breaking plate 57.

[0033] See Figure 7 、 Figure 10 、 Figure 11 and Figure 13 The fermentation tank body 10 is fermented in layers through the fixed plate 11, and the fermentation substrate and fermentation bacteria powder in the upper layer of the fermentation tank body 10 are fully mixed and stirred by the stirring rod 27 on the stirring drum 20 and the supporting rod 31. The cleaning scraper 30 is pressed against the inner wall of the fermentation tank body 10 by the pushing component inside the stirring drum 20, and then the cleaning scraper 30 is rotated to scrape and clean the inside of the fermentation tank body 10. When the fermentation substrate and the fermentation bacteria powder are mixed, the fermentation bacteria powder in the barrel 40 is quantitatively injected through the quantitative component, and the twisting component in the rotating drum 12 is used to drive the scattering plate 57 to twist and stir in the lower layer of the fermentation tank body 10. The scattering amplitude is small, which protects the bacteria in the fermentation product, and then the rotating disk 60 assists in diverging and mixing the fermentation product to prevent the fermentation product from agglomerating.

[0034] See Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8A driving motor 13 and a fermentation cover 14 are provided on the top of the fermentation tank body 10. The top of the mixing drum 20 is installed on the output end of the driving motor 13. A first motor 21 is fixedly installed on the inner top of the mixing drum 20. The output end of the first motor 21 is connected to a screw 22. The screw 22 is threadedly connected to a pushing frame 23 that is movable inside the mixing drum 20. The top of the pushing frame 23 is threadedly connected to the screw 22, and the bottom of the pushing frame 23 is movable through the outer periphery of the screw 22. The pushing assembly also includes a pushing block 32 that is movable inside the support rod 31. The support rod 31 is provided with a fixed slide groove 33 at one end near the mixing drum 20. The pushing block 32 is moved by a fixed slide The groove 33 slides inside the support rod 31, and an L-shaped pushing rod 24 is fixedly installed at the bottom of the pushing frame 23, and a pushing column 25 is fixedly installed at the bottom end of the L-shaped pushing rod 24. The pushing block 32 is provided with an inclined groove 34 that matches the size of the pushing column 25, and the pushing column 25 moves in the inclined groove 34. The pushing block 32 is fixedly installed with a connecting rod 35 at the end away from the mixing drum 20, and the cleaning scraper 30 is fixedly installed at the end of the connecting rod 35 away from the mixing drum 20. A limiting rod 26 is fixedly installed inside the pushing frame 23, and the pushing frame 23 moves through the limiting rod 26. A number of stirring rods 27 for mixing and stirring the fermented material are evenly installed on the periphery of the mixing drum 20.

[0035] See Figure 6 、 Figure 7 and Figure 8 The first motor 21 drives the pushing frame 23 on the screw 22 to realize downward movement under the action of the limiting rod 26, driving the pushing column 25 to descend synchronously. Due to the limitation of the inclined groove 34, the pushing block 32 moves horizontally in the fixed slide groove 33. At this time, the pushing block 32 will move away from the side of the mixing drum 20. The pushing block 32 drives the cleaning scraper 30 to fit the inner wall of the fermentation tank body 10 through the connecting rod 35, and then the driving motor 13 drives the mixing drum 20 to rotate, and the mixing drum 20 drives the cleaning scraper 30 to scrape and clean the adhesion on the inner wall of the fermentation tank body 10.

[0036] See Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 and Figure 11The fixed plate 11 is provided with a discharge hole 15 with an electromagnetic valve, and a plurality of auxiliary rods 68 for assisting in stirring the fermented material after fermentation are evenly installed at the bottom of the rotating disk 60. The torsion assembly also includes a second motor 50 fixedly installed on the rotating cylinder 12, and the second motor 50 is connected to the active swing arm 51 through a rotating shaft. The rotating cylinder 12 is movably provided with a fixed rotating shaft 61 at the end away from the second motor 50, and the fixed rotating shaft 61 is fixedly installed with a driven swing arm 62 at the end close to the second motor 50. The upper and lower ends of the rotating cylinder 12 are connected to the torsion plate 54 through a rotating shaft, and a connecting rotating shaft 55 is fixedly installed between the torsion plates 54. The connecting rotating shaft 55 movably passes through the motion block 63, and the motion block 63 is fixedly installed with a T-shaped motion rod 64. The two ends of the T-shaped motion rod 64 are respectively movably passed through the active swing arm 51 and the driven swing arm 62. The torsion plate 54 at the bottom of the rotating cylinder 12 is equipped with a torsion rod 53, and the breaking plate 57 is evenly installed on the bottom outside of the torsion rod 53.

[0037] See Figure 9 、 Figure 10 and Figure 11 The second motor 50 drives the active swing arm 51 to rotate, and the active swing arm 51 drives the T-shaped motion rod 64 to rotate and swing synchronously. The other end of the T-shaped motion rod 64 will also drive the driven swing arm 62 on the fixed shaft 61 to rotate synchronously. During the rotation process, the active swing arm 51 and the driven swing arm 62 drive the motion block 63 to move on the connecting shaft 55 through the T-shaped motion rod 64. When the motion block 63 rotates to the highest and lowest points of the connecting shaft 55, the torsion plate 54 and the T-shaped motion rod 64 remains horizontal in the vertical direction, and when the moving block 63 rotates to the middle of the connecting shaft 55, the active swing arm 51 and the driven swing arm 62 will move from the vertical state to the horizontal state, driving the misaligned twisting between the torsion plate 54 and the T-shaped motion rod 64, thereby driving the torsion rod 53 under the torsion plate 54 to twist back and forth, and the torsion rod 53 will drive the breaking plate 57, the breaking rod 56 and the annular toggle plate 52 to twist and rotate the fermentation product back and forth, and mix and stir the fermented product.

[0038] See Figure 9 、 Figure 10 and Figure 11 A ring-shaped toggle plate 52 is fixedly installed between the breaking-up plates 57, and a number of breaking-up rods 56 are evenly installed on the breaking-up plate 57 located at the lowest end of the torsion rod 53. A first bevel gear 65 is fixedly installed on the fixed rotating shaft 61 at the end away from the second motor 50. The bottom side of the first bevel gear 65 is meshed with the second bevel gear 66. A rotating shaft 67 is fixedly installed on the bottom of the second bevel gear 66, and the rotating disk 60 is fixedly installed at the bottom end of the rotating shaft 67.

[0039] The fixed rotating shaft 61 on the driven swing arm 62 is driven to rotate by the T-shaped motion rod 64, and the first bevel gear 65 on the fixed rotating shaft 61 engages with the second bevel gear 66 to drive the rotating shaft 67 to rotate synchronously, and the rotating disk 60 under the rotating shaft 67 cooperates with the auxiliary rod 68 to assist in mixing and stirring the fermentation product.

[0040] See Figure 2 、 Figure 3 、 Figure 10 、 Figure 12 and Figure 13 The bottom of the barrel 40 is mounted on the top of the fermentation tank body 10 through the feed seat 70. The bottom of the fermentation tank body 10 is installed with a supporting foot 16. The quantitative component includes a triangular limit seat 41 fixedly mounted on the top of the fermentation tank body 10. The top of the triangular limit seat 41 is provided with a T-shaped slide 42. The triangular limit seat 41 is slidably connected to a T-shaped slider 43 in the T-shaped slide 42. A movable plate 44 is fixedly installed on the top of the T-shaped slider 43. A third motor 46 is connected to one side of the top of the fermentation tank body 10 through a motor seat 45. The output end of the third motor 46 is connected to a rotating disk 47 through a rotating shaft. The rotating disk 47 is fixedly installed with an arc-shaped movable rod 48 for interval-moving the movable plate 44. The movable plate 44 is provided with an arc-shaped groove 49 that matches the arc-shaped movable rod 48, and the arc-shaped movable rod 48 moves in the arc-shaped groove 49. The movable plate 44 is fixedly installed with a connecting rod 71 on the side close to the feed seat 70. The connecting rod 71 is fixedly installed with a feed baffle 72 that moves inside the feed seat 70. A feed channel 73 is provided inside the feed seat 70, and the feed baffle 72 moves in the feed channel 73. The feed baffle 72 has a feed hole 74 that matches the size of the feed channel 73.

[0041] See Figure 10 、 Figure 11 、 Figure 12 and Figure 13 , the rotating disk 47 is driven to rotate by the third motor 46. When the rotating disk 47 drives the movable plate 44 on the limit base to move to one end away from the barrel 40 through the arc motion rod and the arc groove 49, the connecting rod 71 on the movable plate 44 pulls the feeding hole 74 on the feeding baffle 72 to align with the feeding channel 73 of the feeding seat 70, and the feeding channel 73 is opened. The fermentation bacteria powder in the barrel 40 enters the fermentation tank body 10 through the feeding channel 73. When the movable plate 44 approaches one end of the barrel 40, the connecting rod 71 drives the feeding hole 74 on the feeding baffle 72 to be staggered with the feeding channel 73, and the feeding baffle 72 is used to block the feeding channel 73, so that the fermentation bacteria powder no longer enters the fermentation tank body 10, and the fermentation bacteria powder in the barrel 40 is evenly and quantitatively injected into the fermentation tank body 10.

[0042] How it works: See Figure 1 and Figure 2, fermentation bacteria powder is injected into the barrel 40, and the fermentation substrate is injected through the fermentation cover 14 on the top of the fermentation tank body 10. The driving motor 13 drives the stirring drum 20 to rotate inside the fermentation tank body 10. The stirring drum 20 drives the stirring rod 27 and the support rod 31 to mix and stir the fermentation substrate and the fermentation bacteria powder, using the fermentation bacteria powder to expand and multiply, and quickly consumes the easily degradable fermentation substrate.

[0043] See Figure 10 、 Figure 11 、 Figure 12 and Figure 13 When the feed material is fed into the fermentation tank body 10, the third motor 46 on the motor base 45 drives the rotating disk 47 to rotate, and the arc-shaped movable rod 48 of the rotating disk 47 moves in the arc-shaped movable rod 48. When the rotating disk 47 drives the movable plate 44 on the limit base to move away from one end of the barrel 40 through the arc-shaped motion rod, the movable plate 44 pulls the feeding hole 74 on the feeding baffle 72 to align with the feeding channel 73 of the feeding seat 70, and the feeding channel 73 is opened, and the fermentation bacteria powder in the barrel 40 enters the fermentation tank body 10 through the feeding channel 73. When the movable plate 44 is close to one end of the barrel 40, the connecting rod 71 drives the feeding hole 74 on the feeding baffle 72 to stagger with the feeding channel 73, and the feeding baffle 72 is used to block the feeding channel 73, so that the fermentation bacteria powder no longer enters the fermentation tank body 10, thereby realizing the fermentation bacteria powder in the barrel 40 being uniformly and quantitatively injected into the fermentation tank body 10.

[0044] See Figure 9 、 Figure 10 、 Figure 11 After a certain period of fermentation, the discharge hole 15 on the fixed plate 11 is opened to allow the fermented product to enter the bottom of the fermentation tank body 10. The second motor 50 drives the active swing arm 51 to rotate, and the active swing arm 51 drives the T-shaped motion rod 64 to rotate and swing synchronously. The T-shaped motion rod 64 will also drive the driven swing arm 62 on the fixed shaft 61 to move synchronously. The active swing arm 51 and the driven swing arm 62 drive the motion block 63 to move on the connecting shaft 55 during the rotation process. When the motion block 63 is rotated, the motion block 63 is rotated ... When the block 63 rotates to the highest and lowest points of the connecting shaft 55, the torsion plate 54 and the T-shaped motion rod 64 remain horizontal. When the motion block 63 rotates to the middle of the connecting shaft 55, it drives the torsion plate 54 and the T-shaped motion rod 64 to undergo misaligned torsion, thereby driving the torsion rod 53 under the torsion plate 54 to twist back and forth. The torsion rod 53 will drive the breaking plate 57, the breaking rod 56 and the annular toggle plate 52 to twist and rotate the fermentation product back and forth, thereby mixing and stirring the fermented product.

[0045] When the active swing arm 51 drives the fixed rotating shaft 61 on the driven swing arm 62 to rotate through the T-shaped motion rod 64, the first bevel gear 65 on the fixed rotating shaft 61 engages with the second bevel gear 66 to rotate, and the rotating shaft 67 at the bottom of the second bevel gear 66 drives the rotating disk 60 to mix and stir the fermented products in a small range, and the auxiliary rod 68 under the rotating disk 60 cooperates with the breaking plate 57 to mix the fermented products.

[0046] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 After the fermentation tank body 10 is finished fermenting, it is necessary to clean the upper layer inside the fermentation tank body 10 and clean the adhesion of the decomposed substrate on the inner wall of the fermentation tank body 10 during the entire fermentation process. Such adhesion is generally difficult to clean. The first motor 21 drives the pushing frame 23 on the screw 22 to move downward under the limit of the limit rod 26. The pushing frame 23 drives the pushing column 25 to move downward in the inclined groove 34 of the pushing block 32 through the L-shaped pushing rod 24. When the pushing column 25 is in the process of descending, the pushing column 25 is driven to move downward in the inclined groove 34 of the pushing block 32. Due to the limitation of the inclined groove 34, the pushing block 32 moves horizontally in the fixed slide groove 33. At this time, the pushing block 32 will move away from the side of the mixing drum 20. The pushing block 32 drives the cleaning scraper 30 to fit the inner wall of the fermentation tank body 10 through the connecting rod 35, and then drives the mixing drum 20 to rotate through the driving motor 13. The mixing drum 20 drives the cleaning scraper 30 to scrape and clean the adhesion on the inner wall of the fermentation tank body 10, and the cleaning scraper 30 thoroughly cleans the inner wall of the fermentation tank body 10.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
