Description

Technical Field

[0001] The invention relates to the technical field of biological agriculture and related industries, and in particular to a feed secondary fermentation tank and a fermentation method thereof. Background Art

[0017] A secondary fermentation method for feed,

[0018] Step 1: The feed and fermentation liquid to be fermented are pressurized into the connecting ring through a water pump and then enter the water inlet pipe through the connecting ring;

[0019] The second step: the feed enters the fermentation tank from the water inlet pipe, and then begins to accumulate in the fermentation tank. After the feeding is completed, the connecting ring can be sealed to allow the feed and fermentation liquid in the fermentation tank to begin fermentation.

[0020] The present invention provides a feed secondary fermentation tank and a fermentation method thereof, which have the following beneficial effects:

[0021] 1. The present invention provides an injection mechanism. When the extruded feed mixed with the fermentation liquid enters the fermentation tank through the water inlet pipe, the blades in the water inlet pipe are moved. The inclined surface of the blade drives the water inlet pipe to start rotating. The water inlet pipe and the connecting ring are rotatably connected and rotate relatively. Therefore, the water inlet pipe drives the spray plate at the bottom to rotate together, and the fermentation mixture enters the spray plate and is sprayed out through the several spray holes below the spray plate. When a large amount of fermentation mixture is pressurized and put into the fermentation tank, it will naturally spread out evenly through the several spray holes, preventing the fermented materials from adhering to each other after being put in and sinking to the bottom, which affects the fermentation situation.

[0022] 2. The present invention provides an injection mechanism and realizes an outward centrifugal force on the liquid in the spray hole through the rotation of the spray disk, so that when the liquid leaves the spray hole, it will be quickly thrown outward and contact the inner wall of the fermentation tank to start flowing downward along the inner wall of the fermentation tank, thereby avoiding the problem of directly putting the fermentation mixture into the fermentation tank, which would cause a large amount of foam to be generated when the fermentation product and the fermentation liquid are rushed into the fermentation tank when the water level is low, thereby affecting the fermentation stability. By allowing the fermentation mixture to flow evenly along the inner wall of the fermentation tank, it is fully separated, and adhesion and agglomeration to the bottom are reduced, while also ensuring the high efficiency and stability of the fermentation.

[0023] 3. The present invention is provided with an injection mechanism. When the fermentation liquid is injected, the connecting rod, the sliding sleeve A and the sliding sleeve B will automatically descend together and rotate to complete the real-time stirring of the injected fermentation liquid. After the injection is stopped, the built-in springs inside the connecting rod, the sliding sleeve A and the sliding sleeve B will pull them back to their original positions, so that the lifting slider slides and rises on the slide bar, rises above the liquid surface of the fermentation liquid and remains stationary, thereby not participating in the fermentation process and without human control and interference, realizing fully automatic injection mixing and fermentation static recovery, improving work efficiency and ensuring the uniform mixing effect of fermentation.

[0024] 4. The present invention sets a layer turning mechanism so that when the fermentation liquid is injected into the fermentation tank, the connecting rod, the sliding sleeve A and the sliding sleeve B will automatically go down into the accumulated fermentation liquid, and automatically open through the three toggle plates to further penetrate into the bottom of the fermentation liquid and enhance the mixing and layer turning effect of the fermentation liquid, so that when the fermentation liquid is tossed by several toggle plates, it will continuously separate from the hollow part in the middle of the toggle plates, thereby achieving a sufficient layer turning and mixing effect on the fermentation mixture.

DETAILED DESCRIPTION

[0039] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a feed secondary fermentation tank, comprising a fermentation tank 2, a support leg 1 is fixedly connected to the bottom of the fermentation tank 2, and an injection mechanism 3 is arranged on the top of the fermentation tank 2.

[0040] The injection mechanism 3 comprises:

[0041] A connecting ring 301 is a circular sleeve-shaped structure. The inner wall of the connecting ring 301 is rotatably connected to a water inlet pipe 302. The outer wall of the water inlet pipe 302 is fixedly connected to a bearing sleeve 303. The water inlet pipe 302 is rotatably connected to the top of the fermentation tank 2 through the bearing sleeve 303. The connecting ring 301 is used to connect to the water pipe to inject fermented materials.

[0042] The blade 304 is a tilted and twisted plate-like structure. The outer wall of the blade 304 is fixedly connected to the inner wall of the water inlet pipe 302. The other side of the blade 304 is fixedly connected to a rotating shaft 305. The rotating shaft 305 is a circular rod-like structure. The bottom of the water inlet pipe 302 is fixedly connected to a spraying disc 306.

[0043] When in use, the feed and fermentation liquid to be fermented are pressed into the connection ring 301 by a water pump, enter the water inlet pipe 302 through the connection ring 301, and enter the fermentation tank 2 from the water inlet pipe 302, and then begin to accumulate in the fermentation tank 2. After the feeding is completed, the connection ring 301 can be sealed to allow the feed and fermentation liquid in the fermentation tank 2 to start fermentation.

[0044] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0045] The spraying disc 306 is a semicircular block structure, an opening is formed at the top of the spraying disc 306 , and a spraying hole 307 is formed at the bottom of the spraying disc 306 .

[0046] The spray hole 307 is connected to the inside of the water inlet pipe 302 through an opening, and the inside of the water inlet pipe 302 is connected to the inside of the connecting ring 301. A fixing part 308 is fixedly connected to the bottom of the spray plate 306, and a rotating rod 309 is fixedly connected to the bottom of the fixing part 308. One end of the rotating rod 309 is rotatably connected to the bottom of the inner wall of the fermentation tank 2 through a bearing.

[0047] The outer wall of the fixing member 308 is hinged with a hinge block A310, the inner wall of the hinge block A310 is hinged with a connecting rod 311, the outer wall of the connecting rod 311 is slidably connected with a sliding sleeve A312, the outer wall of the sliding sleeve A312 is slidably connected with a sliding sleeve B313, and the connecting rod 311, the sliding sleeve A312 and the sliding sleeve B313 are internally provided with built-in springs.

[0048] One end of the sliding sleeve B313 is hinged with a hinge block B314, the outer wall of the hinge block B314 is fixedly connected with a lifting slider 315, the outer wall of the lifting slider 315 is slidably connected with a slide bar 316, and the outer wall of the slide bar 316 is slidably connected to the inner wall of the fermentation tank 2.

[0049] When the squeezed feed mixed with the fermentation liquid enters the fermentation tank 2 through the water inlet pipe 302, the blade 304 in the water inlet pipe 302 will be moved, and the inclined surface of the blade 304 will drive the water inlet pipe 302 to start rotating. The water inlet pipe 302 and the connecting ring 301 are rotatably connected and rotate relatively, so the water inlet pipe 302 will drive the spray plate 306 at the bottom to rotate together, and the fermentation mixture enters the spray plate 306 and is sprayed out through the several spray holes 307 under the spray plate 306. When a large amount of fermentation mixture is pressurized and put into the fermentation tank 2, it will naturally spread evenly through the several spray holes 307 to prevent the fermented materials from sticking to each other after being put in. The problem of the liquid adhering to each other and sinking to the bottom, which affects the fermentation condition, and the rotation of the spraying plate 306 realizes that the liquid in the spraying hole 307 has an outward centrifugal force, so that when it leaves the spraying hole 307, it will be quickly thrown outward and contact the inner wall of the fermentation tank 2, and start to flow downward along the inner wall of the fermentation tank 2, avoiding the problem that the fermentation mixture is directly put into the fermentation tank 2, which causes a large amount of foam generated when the fermentation material and the fermentation liquid are rushed into it when the water level is low, and the fermentation stability is affected. By allowing the fermentation mixture to flow down evenly along the inner wall of the fermentation tank 2, it is fully separated, reducing adhesion and agglomeration and sinking to the bottom, and also ensuring the high efficiency and stability of the fermentation;

[0050] When the spray disc 306 rotates, it will synchronously drive the rotating rod 309 and the hinge block A310 below to rotate synchronously, and the hinge block A310 will drive the connecting rod 311, the sliding sleeve A312, and the sliding sleeve B313 to rotate synchronously. The sliding sleeve B313 drives the lifting slider 315 to rotate through the hinge block B314, and the lifting slider 315 is connected to the sliding bar 316 in a lifting sliding manner. The five sliding bars 316 are connected to the rotating ring 317, and the rotating ring 317 is on the inner wall of the fermentation tank 2. The hinge block B314 is connected by rotation, so that the sliding bar 316 rotates on the inner wall of the fermentation tank 2 through the lifting slider 315. When the spraying disc 306 does not rotate, the connecting rod 311, the sliding sleeve A312 and the sliding sleeve B313 are pulled back to their original position by the elastic force of the built-in spring. When the spraying disc 306 rotates, the lifting slider 315 is pushed by the hinge block B314 and the sliding sleeve B313 to slide down on the sliding bar 316 due to the centrifugal force. The sleeve B313, the sliding sleeve A312, and the connecting rod 311 change their angles together, and the connecting rod 311 is hinged and rotated on the hinge block A310 to descend, so that when the fermentation liquid is injected, the connecting rod 311, the sliding sleeve A312, and the sliding sleeve B313 will automatically descend together and rotate to complete the real-time stirring of the injected fermentation liquid, and after the injection is stopped, the built-in spring inside the connecting rod 311, the sliding sleeve A312, and the sliding sleeve B313 will pull them back to their original positions, so that the lifting slider 315 slides and rises on the slide bar 316, rises to the surface of the fermentation liquid and remains stationary, so as not to participate in the fermentation process and not to interfere with the fermentation. When injecting, it will automatically rotate and descend through centrifugation, driving the connecting rod 311, the sliding sleeve A312, and the sliding sleeve B313 to stir the liquid and complete automatic mixing, and then no human control and interference are required, so as to realize the fully automatic injection mixing and fermentation static recovery work, improve the work efficiency, and ensure the uniform mixing effect of the fermentation;

[0051] Example 3: Please refer to Figure 1-13 On the basis of the first and second embodiments, the present invention provides a technical solution: a rotating ring 317 is fixedly connected to the top of the slide bar 316, the outer wall of the rotating ring 317 is rotatably connected to the inner wall of the fermentation tank 2, and the outer wall of the sliding sleeve B313 is provided with a layer turning mechanism 4.

[0052] The layer turning mechanism 4 includes an elastic strip 401, one end of which is fixedly connected to the outer wall of the sliding sleeve A312, and the other end of which is fixedly connected to a toggle plate 402, and the outer wall of the toggle plate 402 is fixedly connected to a rotating shaft 403.

[0053] The outer wall of the rotating shaft 403 is rotatably connected to the limit plate 404, and the outer wall of the limit plate 404 is fixedly connected to the outer wall of the sliding sleeve B313. The outer wall of the toggle plate 402 is fixedly connected to a pull rope 405, and the other end of the pull rope 405 is fixedly connected to another toggle plate 402. The outer wall of another toggle plate 402 is fixedly connected to another pull rope 405, and one end of another pull rope 405 is fixedly connected to a third toggle plate 402. The outer wall of the third toggle plate 402 is fixedly connected to an elastic rope 406, and one end of the elastic rope 406 is fixedly connected to the outer wall of the sliding sleeve B313. The bottom of the toggle plate 402 is fixedly connected to a support plate 407, and the support plate 407 is used to support another toggle plate 402.

[0054] When the lifting slider 315 is thrown out and slides down on the slide bar 316, the connecting rod 311, the sliding sleeve A312 and the sliding sleeve B313 are stretched relative to each other, and the internal built-in spring is pulled to deform, so that the distance between the elastic strip 401 on the sliding sleeve A312 and the toggle plate 402 is separated, thereby pulling the toggle plate 402, and the toggle plate 402 is turned down under the rotation of the rotating shaft 403. The toggle plate 402 turns down by itself and the sliding sleeve B313 drives the limiting plate 404 to the circumferential rotation of the toggle plate 402, thereby increasing the stirring area in the fermentation liquid, and deeply stirring and turning the fermentation liquid entering the fermentation tank 2 to avoid sedimentation. At the same time, after the toggle plate 402 is turned up, the pull rope 405 will pull the other toggle plate 402, and the other toggle plate 402 will also be turned up. The third toggle plate 402 is pulled by another pull rope 405 connected thereto, and the third toggle plate 402 is connected to the elastic rope 406 for limiting position, so that all three toggle plates 402 are pulled apart and connected to each other by the pull rope 405, and the pull rope 405 is stretched by elastic deformation, so that each toggle plate 402 rotates and opens, so that when the fermentation liquid is injected into the fermentation tank 2, the connecting rod 311, the sliding sleeve A312, and the sliding sleeve B313 automatically go down to the accumulated fermentation liquid, and automatically open through the three toggle plates 402, further penetrate into the bottom of the fermentation liquid, and enhance the mixing and turning effect of the fermentation liquid, so that when the fermentation liquid is tossed by several toggle plates 402, it will be continuously separated from the hollow part in the middle of the toggle plates 402, so as to achieve a sufficient turning and mixing effect on the fermentation mixture;

[0055] When the injection is stopped, everything is reset. The toggle plate 402 connected to the elastic rope 406 is pulled back to the original position by the elastic rope 406, and the sliding sleeve A312 and the sliding sleeve B313 are reset. The elastic strip 401 pushes the toggle plate 402 back to the original position by elastic force and lifts it up without touching the fermentation liquid. When the toggle plate 402 is lifted up, another toggle plate 402 is lifted up through the supporting plate 407 below, so that all three toggle plates 402 are reset.

When the fermentation liquid is injected, the connecting rod (311), the sliding sleeve A (312), and the sliding sleeve B (313) automatically descend together and rotate together, so as to stir the injected fermentation liquid in real time, and when the injection is stopped, After injection, the internal springs of the connecting rod (311), the sliding sleeve A (312), and the sliding sleeve B (313) pull them back to their original positions, so that the lifting slider (315) slides and rises on the slide bar (316), rises to the surface of the fermentation liquid and remains stationary, so that it does not participate in the fermentation process and does not interfere with the fermentation. When injected, it automatically rotates and descends through centrifugation, driving the connecting rod (311), the sliding sleeve A (312), and the sliding sleeve B (313) to stir the liquid, thereby completing automatic mixing.

2. A feed secondary fermentation method, based on the feed secondary fermentation tank according to claim 1, characterized in that: The first step: the feed and fermentation liquid to be fermented are pressurized into the connecting ring (301) by a water pump, and then enter the water inlet pipe (302) through the connecting ring (301); Step 2: The feed enters the fermentation tank (2) from the water inlet pipe (302) and then begins to accumulate in the fermentation tank (2). After the feed is added, the connecting ring (301) can be sealed to allow the feed and fermentation liquid in the fermentation tank (2) to begin fermentation.
