Description

Technical Field

[0001] This utility model relates to the technical field of refining apparatus for processing chicken oil as a feed additive, and more specifically, it relates to refining apparatus for processing chicken oil as a feed additive. Background Technology

[0002] In the field of modern feed additive production, chicken oil is an important nutritional additive, and its refining quality directly affects the overall nutritional value and palatability of the feed. However, the chicken oil refining equipment currently on the market has many technical defects in the design of the heating system.

[0003] Traditional chicken fat refining equipment for feed additives generally suffers from uneven heating and large temperature fluctuations. Specifically, common refining equipment often uses a single point or a few heating sources to heat the refining tank. This localized heat source design leads to a significant temperature gradient within the tank. This uneven heating state results in insufficient release of the effective components in the chicken fat raw material, which not only affects the extraction efficiency but may also cause oxidation and deterioration of the chicken fat in some high-temperature areas, producing off-flavors and harmful substances. This seriously affects the refining quality of chicken fat and the retention rate of its nutritional components.

[0004] Secondly, to address the aforementioned uneven heating issue, some equipment manufacturers have introduced water bath heating technology, attempting to achieve uniform heating through the circulation of hot water around the tank wall. Theoretically, this method can provide a more balanced heat distribution. However, in practical applications, most water bath heating devices use a fixed flow rate for hot water delivery, lacking the ability to adjust the flow rate in real time according to process requirements. This makes it difficult to provide precise heat control when dealing with different batches of chicken fat raw materials, different refining stages, and different ambient temperature conditions. For example, when the initial temperature of the raw material is low, a higher heat transfer efficiency is needed for rapid heating, while approaching the target temperature requires a reduced heat transfer rate to avoid temperature overshoot. Similarly, in the early and later stages of refining, due to changes in material properties, the optimal heating temperature and rate should also differ. However, a fixed-flow-rate water circulation system cannot adapt to these changing needs, resulting in completely uncontrollable heating temperature and rate. Either insufficient heating affects refining efficiency, or overheating leads to a decline in product quality. In mass production environments, it is particularly difficult to ensure consistent product quality, severely restricting the improvement of production efficiency and the optimization of energy utilization efficiency.

[0005] Furthermore, to address the aforementioned issues, some advanced equipment has attempted to achieve flexible control of the heating medium delivery speed through adjustable flow rate systems. While these systems have initially achieved flow rate regulation, they exhibit significant reliability deficiencies under long-term operating conditions. First, the regulating components are often simply designed and lack necessary fixing measures, making them prone to slight displacement under the long-term impact of high-temperature water flow, causing carefully adjusted settings to gradually deviate. Second, the mechanical vibrations generated during the operation of the refining equipment are transmitted to the regulating components through the structure, accelerating the loosening trend of the regulating mechanism. More seriously, this loosening and deviation often occur gradually and are difficult for operators to detect in time. When the flow rate changes accumulate to a level sufficient to affect the heating effect, it may have already resulted in a large number of defective products. This design, which seems to solve the flow rate regulation problem but introduces stability risks, forces operators to frequently check and readjust the flow rate parameters, increasing labor intensity and operational complexity. Moreover, repeated adjustments make it difficult to standardize the production process, failing to meet the comprehensive requirements of modern feed additive production for high stability, high precision, and low labor input.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a refining device for processing chicken oil as a feed additive, which has the following beneficial effects:

[0019] 1. The heating device innovatively solves the technical problem of uneven heating in traditional chicken oil refining equipment through the ingenious combination of the outer shell, input pipe, inner shell, output pipe, and heating chamber. The biggest technical highlight of this device is the spiral guide plate set in the heating chamber, which makes the heating medium flow along the spiral path, realizing all-round heating of the inner shell, eliminating local hot spots and temperature gradients. At the same time, the stirring rack in the inner shell is linked with the motor, which further enhances the uniform distribution of heat by continuously rotating the mixed materials. This dual heat transfer mechanism of "external circulation heating and internal stirring homogenization" enables heat to be efficiently and evenly transferred to the chicken oil raw materials in the inner shell, ensuring all-round balanced heating from top to bottom and from inside to outside. After completing the heat transfer, the heating medium flows back to the external heater through the output pipe to form a closed-loop circulation system. This not only improves energy utilization efficiency, but also ensures the continuity of the heating process and the stability of temperature through continuous circulation. This innovative heating device effectively solves the problems of insufficient component release and local oxidation and deterioration caused by local heating in traditional equipment, and significantly improves the quality stability and effective component retention rate of chicken oil refining, providing important technical support for feed additive production.

[0020] 2. The speed control device, through the ingenious coordination of connecting pipes, control sleeves, linkage pipes, drive gears, rotating shafts, control plates, and driven wheels, effectively solves the technical defect of non-adjustable flow rate in traditional water bath heating devices. The core innovation of this device lies in its precise flow rate adjustment mechanism: changes in the angle of the control plate and control holes directly alter the flow cross-sectional area within the connecting pipe, thereby achieving precise control of the heating medium flow rate. This design allows operators to flexibly adjust the flow rate of the heating medium according to the specific needs of different refining stages: when the initial temperature of the raw material is low, the flow rate can be increased to improve heat transfer efficiency and rapidly raise the temperature; when approaching the target temperature, the flow rate can be decreased to avoid temperature overshoot; similarly, in the early and late stages of refining, different optimal flow rates can be set according to changes in material characteristics. This flow rate adjustment mechanism greatly improves the accuracy and controllability of the heating process, perfectly adapting to the heating needs of different batches of chicken oil raw materials, different refining stages, and different ambient temperature conditions, ensuring product quality consistency, while optimizing energy utilization efficiency and providing a reliable guarantee for process standardization in mass production.

[0021] 3. The locking mechanism, through the precise coordination of the shifting wheel, circular blocks, moving rod, moving hole, moving plate, moving sleeve, shifting block, and shifting spring, creatively solves the technical problem of insufficient structural stability in traditional adjustable flow rate systems. This mechanism employs a multi-locking design: First, multiple shifting blocks, under the action of the shifting spring, securely engage the shifting wheel between two adjacent circular blocks, forming the first physical lock; second, the moving sleeve, through the tight fit between its inner wall and the outer wall of the shifting wheel, forms the second limiting protection; finally, the shifting plate, through the misalignment of the moving hole and the moving rod, ensures that the moving sleeve cannot move unexpectedly, forming the third safety barrier. Even under harsh conditions such as long-term impact from high-temperature water flow and equipment vibration during operation, this triple locking mechanism can firmly maintain the setting state of the speed regulating device, solving the persistent problem of easy loosening and displacement of traditional regulating components. At the same time, the locking mechanism is also easy to operate: this innovative locking design not only ensures long-term stability of the heating flow rate and avoids product quality fluctuations caused by flow rate drift, but also significantly reduces the frequency of inspection and adjustment by operators, reduces labor intensity, achieves a high degree of standardization of the production process, and perfectly meets the comprehensive requirements of modern feed additive production for high stability, high precision and low labor input.

[0031] Please see Figures 1-5 A refining device for processing chicken oil as a feed additive includes a housing 1, a heating device inside the housing 1, and a speed regulating device on the outside of the housing 1. The speed regulating device includes a connecting pipe 2, a control sleeve 3, a linkage pipe 4, a drive gear 5, a rotating shaft 6, a control plate 7, and a driven wheel 8. The control sleeve 3 is rotatably connected to one end of the connecting pipe 2, and the linkage pipe 4 is fixedly connected to the control sleeve 3, with one end of the linkage pipe 4 inserted into the connecting pipe 2. The drive gear 5 is fixedly mounted at one end of the linkage pipe 4, the rotating shaft 6 is fixedly mounted on one side of the driven wheel 8, and the control plate 7 is fixedly mounted on one side of the driven wheel 8. The driven wheel 8 is rotatably mounted inside the connecting pipe 2 via the rotating shaft 6, and the driven wheel 8 meshes with the drive gear 5. A locking mechanism is provided on the outside of the connecting pipe 2. The locking mechanism includes a shifting wheel 9, a round block 10, a moving rod 11, a moving hole 12, a moving plate 13, a moving sleeve 14, a shifting block 15, and a shifting spring 16. The shifting wheel 9 is rotatably installed on one side of the shifting block 15. The shifting wheel 9 is engaged between two corresponding round blocks 10. Multiple round blocks 10 are fixedly installed on the outer wall of the connecting pipe 2. The moving rod 11 is fixedly installed on one side of the moving sleeve 14. The moving hole 12 is opened on the moving plate 13. The moving sleeve 14 is slidably installed on the outside of the connecting pipe 2. Multiple shifting blocks 15 are movably arranged on one side of the control sleeve 3. The two ends of the shifting spring 16 are respectively connected to two adjacent shifting blocks 15.

[0032] The heating device includes an input pipe 17, an inner shell 18, an output pipe 19, and a heating chamber 20. The input pipe 17 is fixedly connected to the outer wall of the outer shell 1, the inner shell 18 is located inside the outer shell 1, the output pipe 19 is fixedly connected to the bottom of the outer shell 1, and the heating chamber 20 is opened between the outer shell 1 and the inner shell 18. One end of the linkage pipe 4 is inserted into the input pipe 17, and one end of the input pipe 17 is rotatably connected to the control sleeve 3.

[0033] The heating chamber 20 is equipped with a guide plate 21, which has a spiral structure design.

[0034] The top of the outer shell 1 is detachably equipped with a motor 22, and the inner shell 18 is rotatably equipped with a stirring rack 23. The top of the stirring rack 23 passes through the top of the outer shell 1 and is connected to the output end of the motor 22.

[0035] The outer shell 1 has a feed inlet 24 on the top, and a feed cover 25 is detachably provided on the feed inlet 24. The bottom of the inner shell 18 is connected to a discharge pipe 26.

[0036] In this embodiment, when the equipment is needed to refine the oil, the feed cover 25 is first opened, and the raw material is fed into the inner shell 18 through the feed port 24. Then, the heater connected to the connecting pipe 2 is turned on, so that the heater heats the heating medium. After heating, the heating medium is transported through the connecting pipe 2 to the input pipe 17, and then through the input pipe 17 to the heating chamber 20. The heating medium then flows spirally along the guide plate 21 of the spiral structure to achieve uniform heating of the inner shell 18. Then it flows into the bottom of the heating chamber 20 and then flows back to the external heater through the output pipe 19 set at the bottom, realizing the recycling of the heating medium. At the same time, the motor 22 is turned on, so that the motor 22 drives the stirring rack 23 to rotate in the inner shell 18 to achieve stirring and further ensure the uniformity of heating. After the refining is completed, the valve and output pump connected to the discharge pipe 26 are opened to transport the refined chicken oil to the next process.

[0037] Please see Figures 3-5 As a further implementation of the overall equipment: multiple shift rails 27 are fixedly provided on one side of the control sleeve 3, and a shift groove 28 is provided in the shift block 15, which is adapted to the shift rails 27.

[0038] A movable spring 29 is movably sleeved on the outside of the movable rod 11. The movable spring 29 is connected to one side of the movable sleeve 14, and the other end of the movable spring 29 abuts against one side of the movable plate 13.

[0039] The control plate 7 has multiple control holes 30.

[0040] More specifically, when it is necessary to adjust the flow rate of the heating medium, firstly, rotate the moving plate 13 so that the moving plate 13 drives the moving hole 12 to rotate to a position concentric with the moving rod 11. Then, push the moving sleeve 14, which drives the moving rod 11 to slide into the moving hole 12. The moving sleeve 14, in conjunction with the moving plate 13, compresses the moving spring 29. Then, the moving sleeve 14 no longer limits the position of the shift wheel 9. Then, rotate the control sleeve 3 so that the control sleeve 3 drives the shift rail 27 set on one side to rotate. Then, the shift rail 27 drives multiple shift blocks 15 to rotate through the shift groove 28, so that the shift blocks 15 drive... The shifting wheel 9, located on one side, rolls out from between the two circular blocks 10. The shifting wheel 9 then drives the shifting block 15 to slide outwards along the shifting rail 27 and the shifting groove 28. The shifting block 15 then drives the shifting spring 16 to stretch outwards. Simultaneously, the control sleeve 3 drives the inner linkage tube 4 to rotate, causing the linkage tube 4 to drive the active gear 5 at one end to rotate. The active gear 5 then drives the driven wheel 8, which meshes with it, to rotate synchronously. The driven wheel 8 then drives the control plate 7, mounted on one side, to rotate, causing the control plate 7 to change its angle. This, in turn, causes the control plate 7 to drive the control hole 30 to change its angle. The change in angle between the control plate 7 and the control hole 30 alters the flow area within the connecting pipe 2, thereby changing the flow rate. Once the appropriate flow rate is achieved, the control sleeve 3 is stopped from rotating, and the shifting rail 27, in conjunction with the shifting groove 28, drives the shifting block 15 and the shifting wheel 9 to rotate between the corresponding two circular blocks 10. Then, the shifting spring 16 resets, pulling the shifting block 15 inward along the shifting rail 27 and the shifting groove 28, causing the shifting block 15 to engage with the shifting wheel 9 between the corresponding two circular blocks 10. The moving sleeve 14 is then released, and the moving spring 29 pushes the moving sleeve 14 to slide back to its original position. The moving rod 11 slides back to its original position. After the moving spring 29 is fully reset, the moving rod 11 no longer limits the moving hole 12. Then, the moving plate 13 is rotated again, causing the moving plate 13 to rotate the moving hole 12 to a position that does not correspond to the moving rod 11. Then, the moving rod 11 limits and supports the moving sleeve 14 to one side of the moving plate 13, so that the inner wall of the moving sleeve 14 limits the outer wall of the shift wheel 9. This prevents the shift wheel 9 and the shift block 15 from moving outward, thus limiting the control sleeve 3 and preventing the control sleeve 3 from rotating. This ensures the structural stability after the flow rate adjustment and ensures the stable delivery of the heating medium.

[0041] In summary, when using or operating the equipment: First, open the feed cover 25, then feed the raw material into the inner shell 18 through the feed inlet 24. Next, turn on the heater connected to the connecting pipe 2 to heat the heating medium. After heating, the heating medium is transported through the connecting pipe 2 to the input pipe 17, and then through the input pipe 17 to the heating chamber 20. The heating medium then flows spirally along the guide plate 21 of the spiral structure, achieving uniform heating of the inner shell 18. It then flows to the bottom of the heating chamber 20 and returns to the external heater through the output pipe 19 at the bottom, achieving the recycling of the heating medium. Simultaneously, turn on the motor 22 to drive the stirring frame 23 to rotate within the inner shell 18, achieving stirring and further ensuring uniform heating. After refining, open the valve and output pump connected to the discharge pipe 26 to transport the refined chicken oil to the next process.

[0042] When the flow rate of the heating medium needs to be adjusted, firstly, rotate the moving plate 13 so that the moving plate 13 drives the moving hole 12 to rotate to a position concentric with the moving rod 11. Then, push the moving sleeve 14, which drives the moving rod 11 to slide into the moving hole 12. The moving sleeve 14, together with the moving plate 13, presses against the moving spring 29. Then, the moving sleeve 14 no longer limits the position of the shift wheel 9. Then, rotate the control sleeve 3 so that the control sleeve 3 drives the shift rail 27 set on one side to rotate. Then, the shift rail 27 drives multiple shift blocks 15 to rotate through the shift groove 28, so that the shift blocks 15 drive the shift rail 27 on one side to rotate. The shifting wheel 9 rolls out from between the two circular blocks 10, then the shifting wheel 9 drives the shifting block 15 to slide outward along the shifting rail 27 and the shifting groove 28. The shifting block 15 then drives the shifting spring 16 to stretch outward. Simultaneously, the control sleeve 3 drives the inner linkage tube 4 to rotate, causing the linkage tube 4 to drive the active gear 5 at one end to rotate. The active gear 5 then drives the driven wheel 8, which meshes with it, to rotate synchronously. The driven wheel 8 then drives the control plate 7 mounted on one side to rotate, causing the control plate 7 to change its angle. This, in turn, causes the control plate 7 to drive the control hole 30 to change its angle. The change in angle between the control plate 7 and the regulating hole 30 alters the flow area within the connecting pipe 2, thereby changing the flow rate. Once the appropriate flow rate is achieved, the control sleeve 3 is stopped from rotating, and the shifting rail 27, in conjunction with the shifting groove 28, drives the shifting block 15 and the shifting wheel 9 to rotate between the corresponding two circular blocks 10. Then, the shifting spring 16 resets, pulling the shifting block 15 inward along the shifting rail 27 and the shifting groove 28, causing the shifting block 15 to engage with the shifting wheel 9 between the corresponding two circular blocks 10. The moving sleeve 14 is then released, and the moving spring 29 pushes the moving sleeve 14 to slide back to its original position. The moving sleeve 14 then... The movable rod 11 slides back to its original position. After the movable spring 29 is fully reset, the movable rod 11 no longer limits the movable hole 12. Then the movable plate 13 is rotated again, causing the movable plate 13 to drive the movable hole 12 to rotate to a position that does not correspond to the movable rod 11. Then the movable rod 11 limits and supports the movable sleeve 14 to one side of the movable plate 13, so that the inner wall of the movable sleeve 14 limits the outer wall of the shift wheel 9, thereby preventing the shift wheel 9 and the shift block 15 from moving outward, thus limiting the control sleeve 3 and preventing the control sleeve 3 from rotating. This ensures the structural stability after the flow rate adjustment and ensures the stable delivery of the heating medium.

For all the fixed connections mentioned above, welding is preferred.
