Description

Technical Field

[0001] This utility model relates to the technical field of sealed storage devices for chicken fat feed additives, and more specifically, it relates to sealed storage devices for chicken fat feed additives. Background Technology

[0002] In the development of the modern feed industry, chicken oil, as an important nutritional additive, is directly related to the overall quality and effectiveness of feed through its quality maintenance and safe storage. However, the current market for sealed storage devices for chicken oil feed additives suffers from several technical deficiencies.

[0003] Existing sealed storage devices for chicken fat feed additives generally suffer from serious problems due to unreasonable insulation structure design. Most storage devices adopt a simple single-layer metal tank structure, lacking an effective insulation layer design. This makes the storage environment temperature highly susceptible to external climate changes. More seriously, temperature fluctuations cause chicken fat to repeatedly undergo thermal expansion and contraction, accelerating fat emulsification and fatty acid chain breakage, which greatly increases the rate of quality deterioration during storage. This causes huge economic losses and quality control pressure for feed production enterprises that need long-term storage and large-scale use. The lack of a reasonable insulation structure design forces enterprises to increase the frequency of testing or shorten the usage cycle, greatly increasing production costs and management burden.

[0004] Secondly, most chicken fat sealing storage devices on the market currently only use simple storage tanks for sealing and storage. In modern chicken fat storage, to prevent oxidation and deterioration, inert gases such as nitrogen and carbon dioxide are usually filled into the storage tank to replace oxygen. Although this operation effectively extends the shelf life of chicken fat, it also brings additional pressure risks. When the ambient temperature rises, the gas inside the tank expands, causing the internal pressure to rise. Similarly, when the chicken fat itself undergoes microbial action that produces gas or when the oxidation reaction intensifies, it will also lead to an abnormal increase in internal pressure. Without a pressure relief device, this pressure accumulation may damage the sealing structure, causing product leakage and contamination at best, and rupture of the storage tank or even an explosion at worst. This not only causes direct economic losses but also threatens the production environment and personnel safety of enterprises. It is particularly noteworthy that this risk is more significant when inert gas is filled, because the inert gas replacement operation often increases the initial pressure, making the overall system pressure higher. Once an abnormal temperature rise or unexpected gas generation occurs, it is easier to exceed the pressure limit of the tank.

[0005] Furthermore, even though some advanced equipment is equipped with pressure relief devices, the protection thresholds of these devices are usually fixed. In actual production environments, the ideal storage conditions and safety parameters for chicken oil products of different specifications and quality grades vary significantly: high-purity chicken oil has higher requirements for oxidation protection and requires more precise pressure control; while some products with added antioxidants can withstand relatively relaxed pressure fluctuations. At the same time, seasonal temperature changes have a significant impact on the storage system. More importantly, the ideal storage pressure should be adjusted according to the characteristics of specific batches of products, such as different parameters like initial temperature, acid value, and peroxide value, in order to optimize storage conditions and extend shelf life. However, pressure relief devices with fixed thresholds cannot adapt to these complex and ever-changing actual needs. This inflexible design not only fails to provide the optimal storage environment for different products, but also fails to cope with system pressure fluctuations caused by seasonal temperature changes, and cannot optimize storage conditions for specific batches of products. This seriously restricts feed companies' ability to finely control product quality, ultimately affecting the nutritional value and market competitiveness of finished feed. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a sealed storage device for chicken oil feed additives, which has the following beneficial effects: 1. The insulation device effectively solves the technical problem of poor insulation performance in traditional chicken oil storage devices by combining the cavity structure formed between the outer shell and the inner shell with a detachable insulation layer. This insulation device adopts a triple protection design of "outer shell - insulation layer - inner shell". The cavity formed between the outer shell and the inner shell serves as the basic insulation layer, while the detachable special insulation layer in the cavity provides additional heat insulation protection. This design significantly reduces the impact of external temperature fluctuations on the chicken oil in the inner shell, effectively avoiding repeated thermal expansion and contraction of chicken oil caused by drastic temperature changes. This inhibits fat emulsification and fatty acid chain breaking processes, and significantly slows down the rate of quality deterioration during storage. This series of innovative designs significantly reduces the pressure on enterprises to control temperature fluctuations, reduces the frequency of testing, and shortens the usage cycle. It saves feed production enterprises a lot of production costs and management burden, while ensuring the stable quality of chicken oil additives during long-term storage.

[0016] 2. The protective device innovatively solves the prominent problem of the lack of a safe pressure relief mechanism in traditional chicken fat storage devices through the ingenious combination of fixed pipes, fixed rods, pressure relief pipes, connecting rods, springs, fixed frames, protective plates, and push sleeves. The core working principle of this device is to use the preset pressure applied to the protective plate by the spring and the balance mechanism of the internal gas pressure. More innovatively, the connecting rod adopts a variable diameter design. Its wider part forms a seal when it is fitted with the protective plate, while the narrower part provides a gas passage, ensuring that the pressure relief process is controllable and orderly. This pressure relief device can not only effectively prevent damage to the sealing structure and the risk of explosion caused by abnormal increase in internal pressure under inert gas filling conditions, but also realize rapid resealing after pressure relief through an automatic reset mechanism without manual intervention, which greatly improves the safety and reliability of the system and provides a solid guarantee for the safety of the enterprise's production environment and personnel.

[0017] 3. The adjustment mechanism, through the ingenious coordination of the moving hole, fixed block, circular block, shifting spring, shifting block, control sleeve, moving plate, outer sleeve, moving sleeve, moving rod, reset block, and reset spring, creatively solves the technical bottleneck of the traditional pressure relief device's fixed and unadjustable threshold. The essence of this mechanism's design lies in its precise adjustability of the threshold and the stability after adjustment: the operator only needs to simply change the pre-compression degree of the spring to achieve precise adjustment of the pressure relief threshold. Particularly noteworthy is the multi-locking design employed in this adjustment mechanism, ensuring high stability of the adjusted parameters: this multi-safety design maintains the set parameters unchanged even under long-term use and vibration conditions. More importantly, this mechanism achieves the ability to adjust the pressure relief threshold, making... Operators can set optimal pressure relief thresholds for chicken oil products of different specifications and quality grades: higher purity chicken oil can be set with more precise pressure control parameters, while products with added antioxidants can use relatively lenient settings. Similarly, in response to seasonal temperature changes, the pressure relief threshold can be lowered in summer to accommodate gas expansion, while the threshold can be raised in winter to maintain better sealing. For specific batches of products with different characteristics such as initial temperature, acid value, and peroxide value, targeted personalized settings can also be made, truly optimizing storage conditions and extending shelf life. This flexible and precise adjustment capability significantly improves feed companies' level of refined control over product quality, ultimately enhancing the nutritional value and market competitiveness of finished feed.

[0024] The insulation device includes an inner shell 23, an insulation layer 24, and a cavity 25. The insulation layer 24 is detachably installed in the cavity 25. The inner shell 23 is located inside the outer shell 1, and the cavity 25 is opened between the outer shell 1 and the inner shell 23.

[0025] The bottom of the outer shell 1 and the inner shell 23 are detachably provided with a base 26. The inner side of the base 26 has a concave structure. The can lid 2 is provided with a feed pipe 27. The top of the feed pipe 27 is detachably provided with a pipe cap 28. The outer shell 1 is provided with an output pipe 29. One end of the output pipe 29 passes through the outer shell 1 and the inner shell 23 and is connected to the base 26. The side wall of the output pipe 29 is provided with multiple inlet slots 30. In this embodiment, when the device is needed, the pipe cap 28 is opened, and chicken oil is added to the inner shell 23 through the feed pipe 27. After the addition is complete, inert gas can be added as needed. After the filling is complete, the pipe cap 28 is reinstalled on the top of the feed pipe 27, and the output pipe 29 is closed by the connected valve. The concave design of the output pipe 29, the inlet groove 30, and the inner side of the base 26 are all for easy discharge. The double-layer design of the outer shell 1 and the inner shell 23 provides a certain degree of heat preservation. The heat preservation layer 24 set in the cavity 25 further blocks the temperature transmission, thereby effectively reducing the impact of external temperature fluctuations. When the internal pressure exceeds the set threshold, the protective plate 9 is pushed open, allowing The protective plate 9 slides along the connecting rod 6, causing it to slide along the slide rail 31 and the slide groove 32. The protective plate 9 will cause the rubber ring 41 on one side to disengage from the sealing groove 42 in the fixing frame 8. Then, the protective plate 9 and the push frame cooperate to compress the spring 7. Gas will then enter the fixing pipe 3 through the gap between the thinner part of the connecting rod 6 and the protective plate 9, and be discharged through the pressure relief pipe 5. After the pressure is released, the spring 7 pushes the protective plate 9 to slide and reset along the slide rail 31 and the slide groove 32. Then, the protective plate 9 will cause the multiple rubber rings 41 on one side to re-clamp into the sealing groove 42, and the protective plate 9 will move to the wider part of the connecting rod 6 to achieve resealing.

[0026] Please see Figures 3-5 As a further implementation of the overall equipment: multiple slide rails 31 are fixedly provided in the fixed pipe 3, and slide grooves 32 are opened on the outer side of the push sleeve 10 and the protective plate 9, and the slide grooves 32 are adapted to the slide rails 31.

[0027] A reset rod 33 is fixedly provided on one side of the reset block 21, and a reset hole 34 is provided in the fixed block 12. The reset rod 33 slides into the reset hole 34.

[0028] The shift block 15 has a shift groove 35, and a plurality of shift rails 36 are fixedly provided on one side of the control sleeve 16. The shift rails 36 are adapted to the shift groove 35. A shift wheel 37 is rotatably provided on one side of the shift block 15. The shift wheel 37 is engaged between two corresponding round blocks 13.

[0029] A movable spring 38 is movably sleeved on the outside of the movable rod 20. One end of the movable spring 38 is in contact with the movable plate 17. A guide groove 39 is opened on the outside of the fixed tube 3. A guide block 40 is fixedly installed on the inside of the movable sleeve 19. The guide block 40 slides in the guide groove 39.

[0030] The protective plate 9 has multiple rubber rings 41 on one side, and the fixing frame 8 has multiple sealing grooves 42 on one side, with the rubber rings 41 inserted into the sealing grooves 42.

[0031] More specifically, when the pressure relief threshold needs to be adjusted, firstly, the moving plate 17 is rotated forward, causing the reset block 21 mounted on one side to rotate forward. Then, the reset block 21 causes the reset rod 33 to rotate along the reset hole 34 opened in the fixed block 12. Then, the reset block 21 and the fixed block 12 cooperate to compress the reset spring 22. At the same time, the moving plate 17 causes the moving hole 11 to rotate. When the reset spring 22 is compressed to its limit, the moving hole 11 rotates to a position concentric with the moving rod 20. Then, the moving sleeve 19 is pushed, causing the moving sleeve 19 to drive the guide block 40 to slide along the guide groove 39. The moving sleeve 19 also causes the moving rod 20 to slide into the moving hole 11. At the same time, the moving sleeve 19 and the moving plate 17 cooperate to compress the moving spring 38. Sleeve 19 no longer limits the outer side of the shift wheel 37, and then rotates the control sleeve 16 clockwise, causing the control sleeve 16 to drive the shift block 15 to rotate via the shift rail 36 and shift groove 35. Then, the shift block 15 drives the shift wheel 37 to roll out between the two round blocks 13, causing the shift wheel 37 to drive the shift block 15 to slide outward along the shift rail 36 and shift groove 35, and causing the shift block 15 to drive the shift spring 14 to stretch outward. At the same time, the control sleeve 16 drives the inner sleeve set on the inner side to rotate clockwise. Since the inner sleeve is connected to the push sleeve 10 by threads, and the slide rail 31 and slide groove 32 limit the push sleeve 10, the push sleeve 10 will not rotate. Then, the push sleeve 10 will slide along the slide rail 31 and slide groove 32, so that the distance between the push sleeve 10 and the protective plate 9 is... The shortening of the spring 7 by the push sleeve 10 and the protective plate 9 compresses the spring 7 to a certain extent, thus increasing the thrust exerted by the spring 7 on the protective plate 9. This makes the protective plate 9 more difficult to open due to the greater pressure it needs to withstand. To open the protective plate 9 with less pressure, the control sleeve 16 is rotated in the opposite direction. Once the appropriate threshold is reached, the rotation of the control sleeve 16 is stopped, and the shift rail 36 and the shift groove 35 work together to rotate the shift block 15 between the two corresponding circular blocks 13. Then, the shift block 15 moves the shift wheel 37 between the two corresponding circular blocks 13. Finally, the shift spring 14 resets and pulls the shift block 15 to slide inward along the shift rail 36 and the shift groove 35, thus opening the shift plate. The positioning wheel 37 engages between the two corresponding circular blocks 13. Then, the moving sleeve 19 is released. The moving spring 38 pushes the moving sleeve 19, causing the guide block 40 to slide and reset along the guide groove 39. The moving sleeve 19 then causes the moving rod 20 to slide and reset. Once the moving spring 38 is fully reset, the moving rod 20 no longer limits the moving plate 17 through the moving hole 11. Then, the reset spring 22 pushes the reset block 21 to rotate and reset. The reset block 21 then causes the reset rod 33 to rotate and reset along the reset hole 34. Simultaneously, the reset block 21 will rotate and reset the moving hole 11 through the moving plate 17 to a position not concentric with the moving rod 20. The moving rod 20 then provides limiting support for the moving sleeve 19. Combined with the limiting effect of the guide block 40 and the guide groove 39 on the moving sleeve 19, this prevents the moving sleeve 19 from sliding.Then, the inner wall of the movable sleeve 19 limits the outer side of the shift wheel 37, preventing the shift wheel 37 and the shift block 15 from moving outward. This limits the control sleeve 16 from rotating, thus ensuring the structural stability after threshold adjustment and guaranteeing stable pressure relief protection.

[0032] In summary, during the use or operation of the entire equipment: When the equipment needs to be used, open the pipe cover 28 and add chicken oil into the inner shell 23 through the feed pipe 27. After adding, inert gas can be added as needed. After filling, reinstall the pipe cover 28 onto the top of the feed pipe 27, and the output pipe 29 is closed by the connected valve. The concave design of the output pipe 29, the inlet groove 30, and the inner side of the base 26 are all for easy discharge. The double-layer design of the outer shell 1 and the inner shell 23 provides a certain degree of heat preservation. The heat preservation layer 24 set in the cavity 25 further blocks temperature transmission, thereby effectively reducing the impact of external temperature fluctuations. When the internal pressure exceeds the set threshold, the protective plate 9 is... Pushing open the protective plate 9 causes it to slide along the connecting rod 6 and along the slide rail 31 and the groove 32. The protective plate 9 also causes the rubber ring 41 on one side to disengage from the sealing groove 42 in the fixing frame 8. Then, the protective plate 9 and the pusher frame work together to compress the spring 7. Gas then enters the fixing pipe 3 through the gap between the thinner part of the connecting rod 6 and the protective plate 9, and is discharged through the pressure relief pipe 5. After the pressure is released, the spring 7 pushes the protective plate 9 to slide and reset along the slide rail 31 and the groove 32. Then, the protective plate 9 causes the multiple rubber rings 41 on one side to re-engage into the sealing groove 42, and the protective plate 9 moves to the wider part of the connecting rod 6 to achieve resealing.

[0033] When the pressure relief threshold needs to be adjusted, firstly, rotate the moving plate 17 clockwise, causing the reset block 21 mounted on one side to rotate clockwise. Then, the reset block 21 causes the reset rod 33 to rotate along the reset hole 34 opened in the fixed block 12. Then, the reset block 21 and the fixed block 12 cooperate to compress the reset spring 22. At the same time, the moving plate 17 causes the moving hole 11 to rotate. When the reset spring 22 is compressed to its limit, the moving hole 11 rotates to a position concentric with the moving rod 20. Then, push the moving sleeve 19, causing the moving sleeve 19 to drive the guide block 40 to slide along the guide groove 39. The moving sleeve 19 also causes the moving rod 20 to slide into the moving hole 11. At the same time, the moving sleeve 19 and the moving plate 17 cooperate to compress the moving spring 38. The outer limit of the shift wheel 37 is removed, and then the control sleeve 16 is rotated clockwise. This causes the control sleeve 16 to drive the shift block 15 to rotate via the shift rail 36 and the shift groove 35. Then, the shift block 15 drives the shift wheel 37 to roll out between the two round blocks 13. This causes the shift wheel 37 to drive the shift block 15 to slide outward along the shift rail 36 and the shift groove 35, and causes the shift block 15 to drive the shift spring 14 to stretch outward. At the same time, the control sleeve 16 drives the inner sleeve set on the inner side to rotate clockwise. Since the inner sleeve is connected to the push sleeve 10 by threads and the slide rail 31 and the slide groove 32 limit the push sleeve 10, the push sleeve 10 will not rotate. Then, the push sleeve 10 will slide along the slide rail 31 and the slide groove 32, shortening the distance between the push sleeve 10 and the protective plate 9. This causes the push sleeve 10 and the protective plate 9 to compress the spring 7, increasing the pushing force exerted by the spring 7 on the protective plate 9. This makes the protective plate 9 more difficult to open due to the increased pressure it requires. To open the protective plate 9 with less pressure, the control sleeve 16 is rotated in the opposite direction. Once the appropriate threshold is reached, the rotation of the control sleeve 16 is stopped, and the shift rail 36 and shift groove 35 work together to rotate the shift block 15 between the two corresponding circular blocks 13. Then, the shift block 15 moves the shift wheel 37 between the two corresponding circular blocks 13. Finally, the shift spring 14 resets and pulls the shift block 15 to slide inward along the shift rail 36 and shift groove 35, thus shifting the position. Wheel 37 engages between the two corresponding circular blocks 13. Then, the movable sleeve 19 is released. The movable spring 38 pushes the movable sleeve 19, causing the guide block 40 to slide and reset along the guide groove 39. Then, the movable sleeve 19 causes the movable rod 20 to slide and reset. When the movable spring 38 is fully reset, the movable rod 20 no longer limits the movable plate 17 through the movable hole 11. Then, the reset spring 22 pushes the reset block 21 to rotate and reset. Then, the reset block 21 causes the reset rod 33 to rotate and reset along the reset hole 34. At the same time, the reset block 21 will rotate and reset the movable hole 11 through the movable plate 17 to a position that is not concentric with the movable rod 20. Then, the movable rod 20 provides limiting support for the movable sleeve 19. With the limiting of the movable sleeve 19 by the guide block 40 and the guide groove 39, the movable sleeve 19 will not slide.Then, the inner wall of the movable sleeve 19 limits the outer side of the shift wheel 37, preventing the shift wheel 37 and the shift block 15 from moving outward. This limits the control sleeve 16 from rotating, thus ensuring the structural stability after threshold adjustment and guaranteeing stable pressure relief protection.
