Description

Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, in particular to a high-safety feed additive fermentation equipment. Background Art

[0002] In the production process of feed additives, fermentation equipment is one of the key core devices. With the development of animal husbandry and feed industry, higher requirements are placed on the quality and safety of feed additives. Especially during the fermentation process, the sanitary condition of the equipment directly affects the safety and stability of the final product.

[0003] At present, widely used fermentation equipment usually adopts a built-in stirring mechanism to stir the materials to promote material exchange and uniform heating during the fermentation process. However, this structural design has certain defects in actual application: due to the complex composition of feed additives, some materials have strong adhesion. After fermentation is completed, they are easy to stick to internal components such as the stirring shaft and stirring blades, forming difficult-to-remove residues. These residues not only affect the cleanliness of the equipment, increase the difficulty of cleaning and maintenance costs, but may also cause cross-contamination, thereby affecting the quality and safety of subsequent batches of products.

[0004] In addition, during the fermentation process, as the metabolic activities of microorganisms proceed, a certain amount of gas is often released. Especially when certain specific strains of bacteria are used or regulators are added, the gas production phenomenon is more obvious. If these gases cannot be discharged in time, the internal pressure of the fermentation box will gradually increase. Excessive internal pressure will not only interfere with the normal fermentation environment, affect the fermentation effect and product stability, but long-term operation may also cause the fermentation box to deform, and even cause safety hazards such as sealing failure and leakage. Summary of the Invention

[0005] In view of this, the present invention provides a high-safety feed additive fermentation equipment, which can overcome the shortcomings of existing fermentation equipment in which materials easily stick to the stirring mechanism inside the equipment during use, thereby increasing the difficulty of cleaning and affecting the quality and safety of subsequent batches of products. In addition, the internal air pressure of the fermentation equipment will increase, affecting the fermentation effect and product stability.

[0028] like Figure 3 and Figure 4As shown, the sealing assembly includes a fixed sleeve 11, a vertical rod 12, a connecting spring 13, a block 14 and a one-way valve 15. Four fixed sleeves 11 are symmetrically connected to the top of each fermentation cylinder 6.

A one-way valve 15 is installed in the middle of each block 14. The one-way valve 15 only allows the gas in the fermentation cylinder 6 to be discharged outward to prevent external contamination.

[0029] like Figure 1 、 Figure 5 and Figure 6 As shown, the feeding assembly includes a rotating frame 16, a servo motor 17, a rotating rod 18, a lifting cylinder 19, a guide rod 20, a docking cylinder 21, an elastic tube 22 and a lifting mechanism. The upper part of the connecting frame 5 is rotatably connected to the rotating frame 16, and a servo motor 17 is installed in the middle of the pressure plate 10. The output shaft of the servo motor 17 is connected to the rotating rod 18, and the rotating rod 18 slides through the middle of the rotating frame 16.

The lower front side of the rotating frame 16 is slidably connected to the lifting cylinder 19, and the inner bottom of the lifting cylinder 19 is conical. shape, and four arc-shaped holes 1901 are spaced circumferentially at the lower part of the lifting cylinder 19, and the arc-shaped holes 1901 correspond one to one to the inclined surfaces on the block 14. Three guide rods 20 are connected to the rotating frame 16 at intervals, and a docking cylinder 21 is slidably connected between the three guide rods 20. An elastic tube 22 is connected between the upper end of the lifting cylinder 19 and the lower end of the docking cylinder 21. The rotating frame 16 is provided with a lifting mechanism for driving the lifting cylinder 19 and the docking cylinder 21 to lift and lower; the lifting mechanism includes a mounting frame 23 and a two-way cylinder 24, and two mounting frames 23 are symmetrically connected to the rotating frame 16. The two mounting frames 23 are both equipped with a two-way cylinder 24, and the telescopic rods on the upper and lower sides of the two-way cylinder 24 are respectively connected to the lifting cylinder 19 and the docking cylinder 21.

[0030] like Figure 7 and Figure 8As shown, it also includes a retaining ring 25, a return spring 26, a second drive motor 27 and a baffle 28. The retaining ring 25 is slidably connected to the lower part of the outer wall of the lifting cylinder 19, and the retaining ring 25 blocks the outer side of the arc hole 1901. A return spring 26 is connected between the top of the retaining ring 25 and the upper part of the outer wall of the lifting cylinder 19. The return spring 26 is wrapped around the outer side of the lifting cylinder 19. The second drive motor 27 is installed on the docking cylinder 21. The baffle 28 is rotatably connected inside the docking cylinder 21, and the front end of the rotating shaft of the baffle 28 passes through the outer wall of the docking cylinder 21 and is connected to the output shaft of the second drive motor 27.

[0031] First, the device is installed in the designated position so that the docking cylinder 21 is located directly below the feeding pipe of the feeding device; then each fermentation cylinder 6 is placed in each placement groove 501 respectively, and then the hydraulic cylinder 9 drives the pressure plate 10 to move downward so that the pressure plate 10 is pressed on the top of the fermentation cylinder 6, thereby fixing the position of the fermentation cylinder 6, and then the two-way cylinder 24 drives the lifting cylinder 19 and the docking cylinder 21 to move away from each other (the lifting cylinder 19 moves downward and the docking cylinder 21 moves upward), the elastic tube 22 is stretched so that the docking cylinder 21 can dock with the feeding pipe of the feeding device, and the lifting cylinder 19 will drive the retaining ring 25 to move downward, and then the lifting cylinder 19 and the retaining ring 25 will both pass through the circular hole 1001. When the bottom of the retaining ring 25 is at the top of the fermentation cylinder 6 When in contact, the bottom of the lifting cylinder 19 will just come into contact with the top of the block 14, and the baffle 25 will be blocked by the fermentation cylinder 6 and stop moving downward, while the lifting cylinder 19 will continue to move downward, and the return spring 26 will be compressed, so that the baffle 25 will no longer block the outside of the arc hole 1901, and the lifting cylinder 19 will squeeze the block 14 to move downward, so that the block 14 will no longer block the through hole 601, and the lifting cylinder 19 can pass through the through hole 601 into the fermentation cylinder 6, and the block 14 drives the vertical rod 12 to move downward, and the connecting spring 13 is stretched, and then the baffle 28 is driven by the second drive motor 27 to rotate ninety degrees to open, so that the baffle 28 no longer blocks the inside of the docking cylinder 21, and then the feed additive is delivered to the docking cylinder 21 through the feeding equipment, and the feed additive in the docking cylinder 21 The feed additive will fall down into the lifting cylinder 19 through the elastic tube 22. Since the bottom of the lifting cylinder 19 is conical, the feed additive in the lifting cylinder 19 will fall down into the fermentation cylinder 6 through the arc hole 1901, thereby automatically completing the feeding of the feed additive. When a certain amount of feed additive is loaded into the fermentation cylinder 6, the feeding device is controlled to stop delivering the feed additive, and then the baffle 28 is driven by the second drive motor 27 to rotate 90 degrees and close, so that the baffle 28 blocks the inside of the docking cylinder 21 again, and then the lifting cylinder 19 and the docking cylinder 21 are driven by the two-way cylinder 24 to move to the side close to each other to reset (the lifting cylinder 19 moves upward and the docking cylinder 21 moves downward), and the elastic tube 22 returns to its original state, so that the docking cylinder 21 The feeding pipe of the feeding equipment is separated, and the lifting cylinder 19 is separated from the block 14. At this time, the connecting spring 13 will return to its original state, driving the vertical rod 12 and the block 14 to move upward and reset, so that the block 14 blocks the through hole 601 again. At the same time, the reset spring 26 will return to its original state, so that the retaining ring 25 can block the outside of the arc hole 1901 again. Then the lifting cylinder 19 can drive the retaining ring 25 to move upward and reset and separate from the fermentation cylinder 6. Then the servo motor 17 drives the rotating frame 16 to rotate ninety degrees. The rotating frame 16 can drive the lifting cylinder 19 to rotate ninety degrees to the top of the next fermentation cylinder 6. Repeat the above operation to automatically add the feed additive to the next fermentation cylinder 6. When the appropriate amount of feed additive is added to all the fermentation cylinders 6,The left rotating block 4 can be driven to rotate by the first driving motor 7 and the universal coupling 8, thereby driving the connecting frame 5 and the right rotating block 4 to rotate together, and the connecting frame 5 can drive the fermentation cylinder 6 thereon to rotate, so that the feed additives in the fermentation cylinder 6 can be rolled and mixed inside it, so as to promote the material exchange and uniform heating during the fermentation process. During the rotation of the connecting frame 5 and the fermentation cylinder 6, the pressing plate 10 presses the fermentation cylinder 6, so that the material in the fermentation cylinder 6 can be prevented from splashing out. At the same time, since the baffle 28 blocks the inside of the docking cylinder 21 and the baffle ring 25 blocks the outside of the arc hole 1901, even if there is material remaining in the docking cylinder 21, the baffle 28 blocks the outside of the arc hole 1901. No material splashing will occur inside the receiving cylinder 21, elastic tube 22 and lifting cylinder 19. After mixing is completed, the first drive motor 7 is turned off, and the hydraulic cylinder 9 drives the pressing plate 10 to move upward and reset, so that the pressing plate 10 is separated from the fermentation cylinder 6. The fermentation cylinder 6 can then be replaced to ferment the next batch of feed additives. The removed fermentation cylinder 6 needs to be placed in a designated location, and the one-way valve 15 is connected to the exhaust pipe so that the gas generated by the fermentation inside the fermentation cylinder 6 can be discharged into the designated container through the one-way valve 15 and the exhaust pipe, which is convenient for collection and subsequent resource utilization. The independently designed fermentation cylinder 6 is also easy to clean.
