Abstract
Description
Technical Field
[0001] This invention belongs to the field of solid-liquid mixing technology for fermented feed, and particularly relates to a solid-liquid mixing device for biological fermented feed and its control method. Background Technology
[0002] Bio-fermented feed is a new type of feed made by fermenting feed ingredients with beneficial microorganisms, with microbial fermentation technology as the core. During the fermentation process, microorganisms can decompose the indigestible components in the feed and transform them into easily absorbed small molecule nutrients, thereby improving the nutritional value of the feed. The organic acids, alcohols and other flavor substances produced by fermentation can improve the smell and taste of the feed, increase the animal's feed intake, and are rich in a large number of beneficial microorganisms, such as lactic acid bacteria, yeast and Bacillus. After entering the animal's intestines, they can regulate the intestinal microecological balance and enhance immunity.
[0003] When producing bio-fermented feed, it is necessary to mix solid feed pellets with liquid bacterial solution to promote feed fermentation. Currently, the bacterial solution is usually poured directly into the mixing tank and mixed with the solid feed before stirring. However, because some solid materials are hygroscopic, when the bacterial solution is poured into the mixing tank, the liquid bacterial solution is prone to clumping with the solid materials, which hinders the penetration and uniform diffusion of the liquid bacterial solution. Summary of the Invention
[0004] To address the aforementioned problems, this invention proposes a biological fermentation feed solid-liquid mixing device and its control method, which can more accurately solve the problems described above.
[0005] This invention is achieved through the following technical solution: This invention proposes a solid-liquid mixing device for bio-fermented feed, comprising a base, a storage cylinder fixedly connected to the upper surface of the base, a processing cylinder fixedly connected to the upper surface of the storage cylinder, a conveying cylinder fixedly connected between the processing cylinder and the storage cylinder, the conveying cylinder penetrating the storage cylinder, a discharge port provided on the outer side of the conveying cylinder, a support plate provided on the outer side of the processing cylinder, a vertical pipe slidably arranged on the upper surface of the storage cylinder, three liquid delivery pipes connected to the outer side of the vertical pipe, a spray nozzle installed at the lower end of the liquid delivery pipes, a fixing ring fixedly connected to the outer side of the three liquid delivery pipes, a fixing plate fixedly connected to the lower surface of each fixing ring, and multiple stirring rods fixedly connected to the lower surface of each of the three fixing plates, the stirring rods and the spray nozzles being arranged alternately.
[0006] In one example, a first drive motor is installed inside the base. The main shaft of the first drive motor is fixedly connected to a round rod. The round rod extends upward through the storage cylinder and the processing cylinder. The round rod is located inside the conveying cylinder. Spiral conveying blades are fixedly connected to the outer side of the round rod. The lower end of the conveying cylinder is open.
[0007] In one example, the processing cylinder has a circular through groove, and a vertical tube is located in the circular through groove. An electric push rod is fixedly connected to the upper surface of the processing cylinder. The telescopic rod of the electric push rod is fixedly connected to a horizontal plate. The vertical tube passes through the horizontal plate and is rotatably connected to the horizontal plate. A second drive motor is fixedly connected to the upper surface of the processing cylinder. A gear is fixedly connected to the main shaft of the second drive motor. A gear ring is rotatably connected to the top inside the processing cylinder. The gear ring meshes with the gear, and the vertical tube passes through the gear ring.
[0008] In one example, the bottom surface of the inner side of the processing cylinder is fixedly connected to an isolation cylinder, and the outer side of the isolation cylinder is provided with multiple square through slots. The vertical pipe passes through the isolation cylinder, and the outer side of the conveying cylinder is provided with two square slots. A slider is slidably connected in the square slots, and the slider is fixedly connected to the support plate. A guide rod is fixedly connected in the square slots, and the guide rod passes through the slider. A first spring is fixedly connected between the slider and the slot.
[0009] In one example, the lower surface of the fixing ring is fixedly connected to three mounting plates, and the lower surface of each of the three mounting plates is fixedly connected to a first scraper.
[0010] In one example, the agitator includes a fixed tube, which is fixedly connected to a fixed plate. A sliding rod is slidably connected inside the fixed tube, and a second spring is fixedly connected between the sliding rod and the fixed tube.
[0011] In one example, a rotating plate is rotatably connected between the isolation cylinder and the processing cylinder. Multiple vertical rods are fixedly connected to the lower surface of the rotating plate, and a second scraper is fixedly connected to the lower end of each vertical rod. The lower surface of the second scraper abuts against the bottom surface inside the processing cylinder. A toggle rod is fixedly connected to the outside of the vertical tube. One end of the toggle rod passes downward through the rotating plate and is slidably connected to the rotating plate.
[0012] In one example, the bottom surface inside the processing cylinder is conical, and the side wall of the processing cylinder is fixedly connected to a discharge pipe.
[0013] A method for controlling the solid-liquid mixing of bio-fermented feed includes the following steps: Step 1: The first drive motor starts, driving the spiral blades to rotate, causing the solid material in the storage cylinder to rise into the processing cylinder and fall onto the tray; Step 2: The second drive motor drives the vertical pipe to rotate through gears and a gear ring. The vertical pipe drives the stirring rod and the spray nozzle to rotate. The stirring rod moves the material, so that the solid material is spread out on the pallet. The bacterial liquid is transported to the spray nozzle through the vertical pipe and sprayed out in a mist. Step 3: The electric push rod pushes the vertical pipe down, causing the stirring rod to push the support plate down, so that the support plate is lowered to the square through groove of the isolation cylinder. The vertical pipe continues to rotate, causing multiple first scrapers to rotate on the support plate, scraping the material and causing the material to gather on one side of the first scraper. As the first scraper rotates, under the action of centrifugal force, the material is thrown out of the isolation cylinder and falls into the processing cylinder. Step 4: The first spring pushes the tray to reset, and solid-liquid mixing continues. The vertical tube rotates, driving the stirring rod to stir the material on the tray. The vertical tube drives the rotating plate to rotate through the stirring rod. The rotating plate drives the second scraper to scrape the already processed material at the bottom of the processing cylinder, causing the material to move. Under the action of centrifugal force, the material enters the discharge pipe and leaves the processing cylinder.
[0014] The bio-fermented feed solid-liquid mixing equipment and its control method proposed in this invention can bring the following beneficial effects: Firstly, by setting up a vertical pipe and a stirring rod, solid materials fall onto the tray after being discharged from the discharge port on the conveying pipe. Rotating the vertical pipe drives the spray nozzle and the stirring rod to rotate, first stirring and spreading the material. The bacterial solution is then transported to the spray nozzle through the vertical pipe and sprayed out in a mist. When spraying, the stirring rod continuously stirs the material to turn over the solid material, avoiding the formation of grooves. By continuously turning over the solid material while spraying the bacterial solution, the mixing effect between the solid material and the bacterial solution is improved, avoiding uneven distribution of the bacterial solution and affecting feed fermentation. Secondly, by setting up a first scraper, after the solid material on the tray is mixed with the bacterial solution, the vertical pipe descends, causing the first scraper to press against the tray and push it down to the square through groove. Then the vertical pipe continues to rotate, causing multiple first scrapers to rotate on the tray, scraping the material and causing it to accumulate on one side of the first scraper. As the first scraper rotates, under the action of centrifugal force, the material is thrown out of the isolation cylinder and falls into the processing cylinder, which facilitates the cleaning of the material on the tray and can speed up the process and reduce residue. Thirdly, by setting a second scraper, when the pallet is reset and solid-liquid mixing continues, the vertical pipe drives the stirring rod to stir the material on the pallet. At the same time, the vertical pipe drives the rotating plate to rotate through the actuating rod. The rotating plate drives the second scraper to scrape the material that has been processed at the bottom of the processing cylinder, so that the material moves. When the material reaches the discharge pipe, the processed material enters the discharge pipe and leaves the processing cylinder under the action of centrifugal force. Attached Figure Description

[0023] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.
[0024] like Figures 1-6As shown, an embodiment of the present invention proposes a solid-liquid mixing device for bio-fermented feed, characterized in that it includes a base 1, a storage cylinder 2 fixedly connected to the upper surface of the base 1, a processing cylinder 3 fixedly connected to the upper surface of the storage cylinder 2, a conveying cylinder 4 fixedly connected between the processing cylinder 3 and the storage cylinder 2, the conveying cylinder 4 penetrating the storage cylinder 2, a discharge port provided on the outer side of the conveying cylinder 4, a support plate 5 provided on the outer side of the processing cylinder 3, a vertical pipe 6 slidably arranged on the upper surface of the storage cylinder 2, three liquid delivery pipes 7 connected to the outer side of the vertical pipe 6, and a spray nozzle installed at the lower end of the liquid delivery pipes 7. The head 8 and the three infusion tubes 7 are fixedly connected to the outer side of the fixing rings 9. The lower surface of each fixing ring 9 is fixedly connected to the fixing plate 10. The lower surface of each of the three fixing plates 10 is fixedly connected to multiple stirring rods 11. The stirring rods 11 are staggered with the spray nozzles 8. This device is placed in a sterile workshop. The side wall of the storage cylinder 2 is connected to the feeding pipe. The storage cylinder 2 stores solid materials. The conveying cylinder 4 is used to convey the solid materials in the storage cylinder 2 upward into the processing cylinder 3. Compared with downward conveying, when the material is conveyed upward, it falls into the tray after leaving the conveying cylinder 4. On plate 5, the degree of material accumulation can be reduced to a certain extent. Only a certain weight of solid material is conveyed at a time. After the solid material detaches from the discharge port on the conveying pipe, it falls onto plate 5. Plate 5 is annular, and solid material tends to clump together on it. At this time, the vertical pipe 6 is rotated, which drives the spray nozzle 8 and the stirring rod 11 to rotate. The lower end of the stirring rod 11 abuts against plate 5. When rotating, the stirring rod 11 moves the material, causing the solid material to spread out evenly on plate 5. A rotating joint is installed at the upper end of the vertical pipe 6. The upper end is connected to a flexible hose, one end of which is connected to the bacterial solution storage tank. A water pump is installed between the bacterial solution storage tank and the flexible hose. When the solid material is spread on the tray 5, the water pump draws out the bacterial solution and delivers it to the spray nozzle 8 through the vertical pipe 6. The solution is then sprayed out in a mist. At the same time, the stirring rods continuously stir the material. The rotation trajectories of all the stirring rods are different, which can both turn the solid material over and avoid the formation of grooves. By continuously turning the solid material over, the mixing effect between the solid material and the bacterial solution is improved, and the uneven distribution of the bacterial solution is avoided, which would affect the fermentation of the feed.
[0025] like Figure 2 As shown, a first drive motor 12 is installed inside the base 1. The main shaft of the first drive motor 12 is fixedly connected to a round rod. The round rod passes through the storage cylinder 2 and the processing cylinder 3 upwards. The round rod is located inside the conveying cylinder 4. A spiral conveying blade 13 is fixedly connected to the outside of the round rod. The lower end of the conveying cylinder 4 is open. When conveying solid materials, the first drive motor 12 starts and drives the spiral blade to rotate, causing the solid materials in the storage cylinder 2 to rise. The lower end of the storage cylinder 2 is conical, which facilitates the accumulation of materials at the opening at the lower end of the conveying cylinder 4, and facilitates the upward conveying of materials by the spiral conveying blade 13. When it reaches the discharge port, it leaves the conveying cylinder 4 under the swinging of the spiral conveying blade 13 and falls onto the pallet 5.
[0026] like Figure 2As shown, the processing cylinder 3 has a circular through groove, and the vertical tube 6 is located in the circular through groove. An electric push rod 14 is fixedly connected to the upper surface of the processing cylinder 3. The telescopic rod of the electric push rod 14 is fixedly connected to the horizontal plate 15. The vertical tube 6 passes through the horizontal plate 15 and is rotatably connected to the horizontal plate 15. A second drive motor 16 is fixedly connected to the upper surface of the processing cylinder 3. The main shaft of the second drive motor 16 is fixedly connected to a gear 17. A gear ring 18 is rotatably connected to the top inside the processing cylinder 3. The gear ring 18 meshes with the gear 17. The vertical tube 6 passes through the gear ring 18. When the material falls onto the pallet 5, the stirring rod 11 abuts against the pallet 5. The second drive motor 16 drives the vertical tube 6 to rotate through the gear 17 and the gear ring 18. The vertical pipe 6 drives the stirring rod 11 and the spray nozzle 8 to rotate, stirring the material and spraying bacterial solution. After spraying, the electric push rod 14 pushes the vertical pipe 6 down, causing the stirring rod 11 to push the tray 5 down, so that the tray 5 falls to the square through slot of the isolation cylinder 19. The staff takes out the material on the tray 5 through the square through slot, so that the mixed material enters the treatment cylinder 3. The tray 5 rises back to its original position, waiting for the conveying cylinder 4 to transport the material to the tray 5 for the second time, so as to stir and spray bacterial solution for continuous processing. A key is provided between the vertical pipe 6 and the toothed ring 18, so that the vertical pipe 6 can slide on the toothed ring 18, and the toothed ring 18 can drive the vertical pipe 6 to rotate.
[0027] like Figure 2 and Figure 3 As shown, the bottom surface of the processing cylinder 3 is fixedly connected to the isolation cylinder 19. The outer side of the isolation cylinder 19 is provided with multiple square through slots. The vertical pipe 6 passes through the isolation cylinder 19. The outer side of the conveying cylinder 4 is provided with two square slots. The slider 20 is slidably connected in the square slots. The slider 20 is fixedly connected to the pallet 5. The guide rod 21 is fixedly connected in the square slots. The guide rod 21 passes through the slider 20. The first spring 22 is fixedly connected between the slider 20 and the trough. When the solid material on the pallet 5 is mixed with the bacterial liquid, it descends to the square through slot for unloading. During this process, the first spring 22 is compressed. When the unloading is completed, the first spring 22 pushes the pallet 5 to reset and continue the solid-liquid mixing.
[0028] like Figure 4 , Figure 5 as well as Figure 6As shown, three mounting plates 23 are fixedly connected to the lower surface of the fixed ring 9. The lower surfaces of the three mounting plates 23 are all fixedly connected to the first scraper 24. The stirring rod 11 includes a fixed tube 111, which is fixedly connected to the fixed plate 10. A sliding rod 112 is slidably connected inside the fixed tube 111. A second spring is fixedly connected between the sliding rod 112 and the fixed tube 111. When the solid material on the tray 5 is mixed with the bacterial liquid, the vertical pipe 6 descends, the fixed tube 111 descends, and the sliding rod 112 retracts into the fixed tube 111, so that the first scraper 24 abuts against the tray 5, pushing the tray 5 down to the square through groove. Then the vertical pipe 6 continues to rotate, so that multiple first scrapers 24 rotate on the tray 5, scraping the material and causing the material to gather on one side of the first scraper 24. As the first scraper 24 rotates, under the action of centrifugal force, the material is thrown out of the isolation cylinder 19 and falls into the processing cylinder 3. When the material on the tray 5 is cleaned by the first scraper 24, the speed is accelerated and the residue is reduced.
[0029] like Figure 4 , Figure 5 as well as Figure 6 As shown, a rotating plate 25 is rotatably connected between the isolation cylinder 19 and the processing cylinder 3. Multiple vertical rods 26 are fixedly connected to the lower surface of the rotating plate 25, and a second scraper 27 is fixedly connected to the lower end of each vertical rod 26. The lower surface of the second scraper 27 rests against the bottom surface inside the processing cylinder 3. A toggle rod 28 is fixedly connected to the outer side of the vertical pipe 6. One end of the toggle rod 28 penetrates downwards through the rotating plate 25 and is slidably connected to it. The bottom surface inside the processing cylinder 3 is conical. A discharge pipe is fixedly connected to the side wall of the processing cylinder 3. When the mixed material on the pallet 5 is discharged into... Inside the processing cylinder 3, because the bottom surface of the processing cylinder 3 is conical, the mixed material gathers on the side inside the processing cylinder 3, while the tray 5 returns to its original position and continues to mix. When the vertical pipe 6 rotates, it drives the stirring rod 11 to stir the material on the tray 5. The vertical pipe 6 drives the rotating plate 25 to rotate through the actuating rod 28. The rotating plate 25 drives the second scraper 27 to scrape the already processed material at the bottom of the processing cylinder 3, causing the material to move. When the material reaches the discharge pipe, the already processed material enters the discharge pipe and leaves the processing cylinder 3 under the action of centrifugal force.
[0030] A method for controlling the solid-liquid mixing of bio-fermented feed, using the bio-fermented feed solid-liquid mixing equipment according to claims 1-8, includes the following steps: Step 1: The first drive motor 12 starts, driving the spiral blades to rotate, causing the solid material in the storage cylinder 2 to rise into the processing cylinder 3 and fall onto the tray 5; Step 2: The second drive motor 16 drives the vertical pipe 6 to rotate through the gear 17 and the gear ring 18. The vertical pipe 6 drives the stirring rod 11 and the spray nozzle 8 to rotate. The stirring rod 11 moves the material, so that the solid material is spread out on the pallet 5. The bacterial liquid is transported to the spray nozzle 8 through the vertical pipe 6 and sprayed out in a mist. Step 3: The electric push rod 14 pushes the vertical pipe 6 down, causing the stirring rod 11 to push the support plate 5 down, so that the support plate 5 is lowered to the square through groove of the isolation cylinder 19. The vertical pipe 6 continues to rotate, causing multiple first scrapers 24 to rotate on the support plate 5, scraping the material and causing the material to gather on one side of the first scraper 24. As the first scraper 24 rotates, under the action of centrifugal force, the material is thrown out of the isolation cylinder 19 and falls into the processing cylinder 3. Step 4: The first spring 22 pushes the tray 5 to reset, and the solid-liquid mixing continues. The vertical pipe 6 rotates, driving the stirring rod 11 to stir the material on the tray 5. The vertical pipe 6 drives the rotating plate 25 to rotate through the stirring rod 11. The rotating plate 25 drives the second scraper 27 to scrape the material that has been processed at the bottom of the processing cylinder 3, causing the material to move. Under the action of centrifugal force, the material enters the discharge pipe and leaves the processing cylinder 3.
