Description

Technical Field

[0001] This invention relates to the field of dry heat sterilization cabinet technology, and in particular to a multi-layer dry heat sterilization device for the production of erythromycin eye ointment. Background Technology

[0002] The multi-layer dry heat sterilization device for the production of erythromycin eye ointment is applied to the aseptic production process of erythromycin eye ointment. It adopts the principle of dry heat air sterilization and has a multi-layer bearing structure (multi-layer shelves, multi-layer mesh belt / conveyor layer) inside the equipment. It sterilizes and removes pyrogens from materials that are not resistant to moisture and heat, such as eye ointment packaging containers, production equipment, and oil phase matrix. It is a special closed high-temperature sterilization device that complies with the GMP specifications for pharmaceuticals.

[0003] Currently, workers place the filled aluminum tubes of erythromycin eye ointment onto high-temperature resistant metal trays, and then sequentially send several trays into the multi-layer shelves of a dry heat sterilizer. During placement, the aluminum tubes must be uniformly placed horizontally and evenly, avoiding stacking or compression, to ensure smooth circulation of hot air within the sterilizer and even heating of all tubes, thus guaranteeing the sterilization effect. After placement, the sterilization process can be started. The sterilizer heats up naturally, and once the internal temperature reaches the specified sterilization temperature for the aluminum tubes, a constant temperature timer is initiated to maintain the specified time to meet sterilization standards. However, during the process of transferring trays to the shelves, the trays are prone to shifting due to accidental contact by workers or the movement of hot air within the cabinet, causing the aluminum tubes to stick together, resulting in uneven heating and affecting the sterilization effect. To ensure all aluminum tubes reach the required sterilization temperature, the operating time of the sterilizer's heating phase must be extended, thus increasing equipment energy consumption. Therefore, this invention provides a multi-layer dry heat sterilization device for erythromycin eye ointment production to meet this requirement. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a multi-layer dry heat sterilization device for the production of erythromycin eye ointment. By setting auxiliary components, it can not only increase the heating rate of aluminum tubes during the operation of the dry heat sterilization cabinet and shorten the working time of the dry heat sterilization cabinet, thereby reducing the energy consumption of the equipment, but also complete the positioning and fixing of aluminum tubes before they are placed on the shelf. This prevents multiple aluminum tubes from sticking together due to operator error during the transfer stage or displacement caused by the hot airflow during the sterilization stage, ensuring uniform heating of the aluminum tubes and effectively improving the overall sterilization effect. This solves the problem of uneven heating of individual aluminum tubes caused by mutual sticking, which in turn prolongs the heating time of the dry heat sterilization cabinet and increases the energy consumption of the equipment.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting auxiliary components, not only can the heating rate of aluminum tubes be increased during the operation of the dry heat sterilizer, shortening the working time of the dry heat sterilizer and thus reducing the energy consumption of the equipment; it can also complete the positioning and fixing of aluminum tubes before they are placed on the shelf, preventing multiple aluminum tubes from sticking together due to operator mishandling during the transfer stage or displacement caused by the hot airflow during the sterilization stage, ensuring uniform heating of aluminum tubes and effectively improving the overall sterilization effect.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0022] The multi-layer dry heat sterilization apparatus for the production of erythromycin eye ointment provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0023] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0024] like Figures 1 to 10As shown, an embodiment of the present invention provides a multi-layer dry heat sterilization device for the production of erythromycin eye ointment, including a dry heat sterilization cabinet 1. A shelf 2 is installed inside the dry heat sterilization cabinet 1, and a tray base 3 is installed on the shelf 2. The tray base 3 is a U-shaped metal plate. Several first clearance grooves 4 are symmetrically formed on the outer walls of both sides of the tray base 3. The first clearance grooves 4 are square grooves, and there are four first clearance grooves 4 in total, arranged symmetrically in pairs. First guide plates 7 are symmetrically fixedly connected to the inner walls of both sides of the tray base 3 near the top. The first guide plates 7 are inclined square metal plates. The outer walls of both sides of the tray base 3 near the first clearance grooves 4... A fixed connection is provided, consisting of four square metal plates, arranged symmetrically in pairs. A first handle 6, a cylindrical metal cylinder, is fixedly connected to the end of each connecting column 5 furthest from the tray base 3. The ends of the two connecting columns 5 on the same side of the tray base 3 furthest from the tray base 3 are both fixedly connected to the outer wall of the same first handle 6. Operators can grip two first handles 6 to place and remove the tray base 3. An auxiliary component is installed on the tray base 3 to increase the heating rate of the aluminum tube. This auxiliary component includes several first partitions 8 and several first sliding grooves 18. The first partition 8 is fixedly connected to the bottom inner wall of the tray base 3. Several first partitions 8 are arranged in a linear array. The first partition 8 is a square metal plate. Several second partitions 9 are symmetrically fixedly connected to the outer walls of both sides of the first partition 8. The second partitions 9 are inclined square metal plates. The overall outline formed by the cooperation between the first partitions 8 and the second partitions 9 is fishbone shaped. In use, the operator places aluminum tubes in the gaps between every two first partitions 8. In the heating section of the dry heat sterilizer 1, hot air blows from one side of the tray base 3 to the other side and passes through the gaps between every two first partitions 8. When the hot air flows through the gaps, it is affected by the fixed connection. The second partitions 9 on the outer walls of both sides of the first partition 8 guide the airflow to form a circulation. With the cooperation of multiple second partitions 9, the flow rate of hot air passing through the gap can be slowed down, allowing the aluminum tube to absorb the heat carried by the hot air more fully. By setting auxiliary components, this application can not only increase the heating rate of the aluminum tube during the operation of the dry heat sterilizer 1 and shorten the working time of the dry heat sterilizer 1, thereby reducing the energy consumption of the equipment; it can also complete the positioning and fixing of the aluminum tube before placing it on the shelf 2, avoiding multiple aluminum tubes from sticking together due to operator mishandling during the transfer stage or displacement caused by the hot air flow during the sterilization stage, ensuring uniform heating of the aluminum tube and effectively improving the overall sterilization effect.

[0025] As one implementation method in this embodiment, such as Figures 3 to 5 and Figure 9As shown, several first sliding grooves 18 are symmetrically formed on the inner walls of both sides of the first clearance groove 4. Each first sliding groove 18 is a circular groove. A sliding post 19 is slidably connected to the inner wall of the first sliding groove 18. The sliding post 19 is a circular metal cylinder. Because the outer contour of the sliding post 19 matches the inner contour of the first sliding groove 18, the sliding post 19 can slide on the inner wall of the first sliding groove 18. A limiting plate 20 is fixedly connected to one end of the sliding post 19 near the central axis of the first clearance groove 4. The limiting plate 20 is a square metal plate, and its outer contour matches the inner contour of the first clearance groove 4. The limiting plate 20 can slide on the inner wall of the first clearance groove 4. A spring 21 is sleeved on the outer wall of the sliding column 19. One end of the spring 21 is fixedly connected to the outer wall of the first clearance groove 4 near the first sliding groove 18, and the other end of the spring 21 is fixedly connected to the outer wall of the limiting plate 20 near the first sliding groove 18. When the limiting plate 20 is subjected to force and slides along the inner wall of the first clearance groove 4 toward the first sliding groove 18, the sliding column 19 will slide synchronously along the inner wall of the first sliding groove 18 under the action of the limiting plate 20. At this time, the spring 21 will be subjected to force and deform along its bending direction.

[0026] like Figures 7 to 9 As shown, a limiting block 22 is fixedly connected to the outer wall of the limiting plate 20 on the side away from the sliding column 19. The limiting block 22 is a metal triangular prism. A second abutting block 23 is fixedly connected to the bottom outer wall of the limiting plate 20 on the side away from the sliding column 19. The second abutting block 23 is a trapezoidal metal column. A sliding cylinder 38 is fixedly connected to the top inner wall of the first clearance groove 4. The sliding cylinder 38 is a metal cylinder. A first sliding plate 24 is slidably connected to the outer wall of the sliding cylinder 38. The first sliding plate 24 is a square metal plate. A second sliding groove 25 is formed on the outer wall of the first sliding plate 24. The second sliding groove 25 is a circular groove. Because the inner contour of the second sliding groove 25 is similar to the outer contour of the sliding cylinder 38... The first sliding plate 24 can slide along the outer wall of the sliding cylinder 38. A tension spring 39 is sleeved on the outer wall of the sliding cylinder 38. One end of the tension spring 39 is fixedly connected to the top inner wall of the first clearance groove 4, and the other end of the tension spring 39 is fixedly connected to the top outer wall of the first sliding plate 24. When the tension spring 39 is subjected to force, it will deform along its bending direction. A support plate 26 is fixedly connected to the outer wall of the first sliding plate 24 near the central axis of the tray base 3. The support plate 26 is a square metal plate. A third guide plate 27 is symmetrically fixedly connected to the outer walls of both sides of the support plate 26. The third guide plate 27 is an inclined square metal plate. The third guide plate 27 can cooperate with the first guide plate 7 to guide the hot air.

[0027] When the staff prepares to place the aluminum tube onto this device, they can first press the tray plate 26 towards the bottom of the tray base 3. At this time, the tray base 3 will drive the four first sliding plates 24 to slide synchronously towards the bottom of the tray base 3 along the outer walls of the four sliding cylinders 38. Simultaneously, the tension spring 39 will be stressed and deform along its bending direction. During this process, the two sides of the first sliding plate 24 will respectively abut against the inclined surfaces of the two limiting blocks 22. At this time, the limiting blocks 22 will drive the limiting plate 20 to slide along the inner wall of the first clearance groove 4 towards the first sliding groove 18. The sliding column 19 will slide synchronously along the inner wall of the first sliding groove 18 under the drive of the limiting plate 20. The spring 21 will be stressed and deform along its bending direction until the first sliding plate 24 no longer abuts against the inclined surface of the limiting block 22. At this time, the spring 21 will no longer be stressed and deform along its bending direction. The curved direction restores the deformation and drives the limiting plate 20 to slide along the inner wall of the first clearance groove 4 towards the central axis of the first clearance groove 4. At the same time, the sliding column 19 will slide synchronously along the inner wall of the first sliding groove 18 under the action of the limiting plate 20. The limiting block 22 will move synchronously towards the central axis of the first clearance groove 4 under the action of the limiting plate 20. At this time, the top outer wall of the first sliding plate 24 will abut against the bottom outer wall of the limiting block 22. In this way, the first sliding plate 24 will be limited by the limiting block 22, so that the tension spring 39 remains in a deformed state. The above structure not only allows the pressing of the tray 26 to fix the pressed tray 26 in an appropriate position, which is convenient for subsequent aluminum tube positioning and fixing; it can also guide the hot air inside the dry heat sterilizer 1 during the sterilization process, allowing the aluminum tube on this device to fully absorb the heat of the hot air, shortening the heating time of the aluminum tube and reducing the energy consumption of the equipment.

[0028] As one implementation method in this embodiment, such as Figure 7 and Figure 8 As shown, the top outer wall of the tray 26 is provided with several second clearance grooves 28 arranged in a linear array. The second clearance grooves 28 are fishbone-shaped grooves. The inner wall contour of the second clearance grooves 28 is adapted to the outer wall contour formed by the cooperation of the first partition 8 and the second partition 9. Therefore, the second clearance grooves 28 can provide clearance space for the first partition 8 and the second partition 9 during the movement of the tray 26. The top outer wall of the tray 26 is provided with several pairs of third clearance grooves 29 arranged in a linear array. The third clearance grooves 29 are square grooves, and two third clearance grooves 29 are a pair. Each pair of third clearance grooves 29 is opened between two second clearance grooves 28. A third abutment block 30 is fixedly connected to the bottom outer wall of the tray 26 near the third clearance grooves 29. The third abutment block 30 is a square metal column, and the two outer walls of the third abutment block 30 near the bottom are provided with chamfers.

[0029] like Figure 6As shown, several pairs of movable buckles 10 are fixedly connected to the inner bottom wall of the tray base 3. A support plate 11 is rotatably connected to each movable buckle 10. The support plate 11 is a square metal plate. A first elastic plate 12 is fixedly connected to the top of the support plate 11. The first elastic plate 12 is a C-shaped metal plate. When the first elastic plate 12 is subjected to force, it will deform along its bending direction. A second elastic plate 17 is fixedly connected to the outer wall of the support plate 11 near the first elastic plate 12. The second elastic plate 17 is a C-shaped metal plate. When the second elastic plate 17 is subjected to force, it will deform along its bending direction. A first abutting block 16 is fixedly connected to the outer wall of the bottom of the plate 11 away from the second elastic plate 17. The first abutting block 16 is a square metal column. A clamping plate 13 is fixedly connected to the end of the first elastic plate 12 away from the support plate 11. The clamping plate 13 is an arc-shaped metal plate. A second guide plate 14 is fixedly connected to the end of the clamping plate 13 away from the first elastic plate 12. The second guide plate 14 is an inclined square metal plate. Several anti-slip grooves 15 are provided on the outer wall of the clamping plate 13 away from the second elastic plate 17. The anti-slip grooves 15 are square grooves, and the several anti-slip grooves 15 are arranged in an arc-shaped array.

[0030] When the worker presses the tray plate 26 towards the bottom of the tray base 3, the third abutment block 30 moves synchronously with the tray plate 26. At this time, the inclined surface of the bottom of the third abutment block 30 abuts against the outer wall of the first abutment block 16. As the third abutment block 30 abuts, the originally inclined support plate 11 rotates on the movable buckle 10 under the action of the first abutment block 16, and remains perpendicular to the tray base 3. During this process, the first elastic plate 12, the clamping plate 13, and the second guide plate 14 move synchronously with the movable buckle 10. At this time, the second elastic plate 17 is subjected to force and deforms along its bending direction, thus... This facilitates the subsequent fixing of the aluminum tube. When the support plate 26 is no longer limited, the tension spring 39 is no longer under force and returns to its original deformation along its bending direction, driving the first sliding plate 24 to move towards the top of the first clearance groove 4. The support plate 26 will move synchronously with the first sliding plate 24 towards the top of the tray base 3. The third abutment block 30 will move synchronously with the support plate 26. At this time, the inclined surface at the bottom of the third abutment block 30 no longer abuts against the outer wall of the first abutment block 16. The second elastic plate 17 is no longer under force and returns to its original deformation along its bending direction, driving the support plate 11 to reset. This allows for the subsequent release of the fixing of the aluminum tube. When the staff places the cap of the aluminum tube into the gap between the two first partition plates 8, the cap will slide between the two clamping plates 13 under the guidance of the two second guide plates 14. The clamping plates 13 will tilt due to the pressure of the cap. During this process, the first elastic plate 12 will be stressed and undergo elastic deformation along its own bending direction. At the same time, under the elasticity of the two first elastic plates 12, the corresponding clamping plates 13 will clamp the cap of the aluminum tube. With the help of the anti-slip groove 15, the aluminum tube can be clamped and fixed. The above structure can adapt to different specifications of aluminum tubes within a certain range and complete the positioning and fixing. At the same time, it can also prevent multiple aluminum tubes from shifting and sticking together due to accidental contact by personnel or the impact of hot air flow during sterilization during the transfer process, avoid uneven heating of the aluminum tubes, and ensure the sterilization effect of the dry heat sterilizer 1 on the aluminum tubes.

[0031] As one implementation method in this embodiment, such as Figures 3 to 5 , Figure 9 and Figure 10As shown, a third elastic plate 31 is symmetrically fixedly connected to both ends of the first handle 6. The third elastic plate 31 is a C-shaped metal plate. When the third elastic plate 31 is subjected to force, it will deform along its bending direction. A second handle 32 is fixedly connected to the end of the third elastic plate 31 away from the first handle 6. The second handle 32 is a square metal column. A second sliding plate 33 is symmetrically fixedly connected to both ends of the outer wall of the second handle 32 away from the first handle 6. The second sliding plate 33 is a square metal plate. A third sliding groove 3 is formed on the outer wall of the second sliding plate 33 near the second handle 32. 4. A fourth sliding groove 35 is provided on the outer wall of the second sliding plate 33 away from the second handle 32. The third sliding groove 34 and the fourth sliding groove 35 are both square grooves with arcs at both ends. A fourth abutment block 36 is symmetrically fixedly connected to the outer walls of the second sliding plate 33 near the third sliding groove 34. A fifth abutment block 37 is symmetrically fixedly connected to the outer walls of the second sliding plate 33 near the fourth sliding groove 35. The fourth abutment block 36 and the fifth abutment block 37 are both trapezoidal metal blocks, and the inclined surfaces on the fourth abutment block 36 and the fifth abutment block 37 face the inclined surface on the second abutment block 23.

[0032] After the aluminum tube is sterilized, the worker grasps the first handle 6 and hooks the second handle 32 with their fingers, pulling the second handle 32 towards the first handle 6. At this time, the third elastic plate 31 will be stressed and deform along its bending direction, while the two second sliding plates 33 will move towards the first handle 6 under the action of the second handle 32. Subsequently, the fourth abutment block 36 will move synchronously under the action of the second sliding plate 33. The inclined surface of the fourth abutment block 36 will abut against the inclined surface of the second abutment block 23. Under the pushing of the fourth abutment block 36, the second abutment block 23 will drive the limiting plate 20 along the first clearance. The inner wall of the groove 4 slides towards the first sliding groove 18, and at the same time, the limiting block 22 moves synchronously under the action of the limiting plate 20. At this time, the bottom outer wall of the limiting block 22 no longer abuts against the top outer wall of the first sliding plate 24, thus releasing the limiting of the tray 26. This releases the fixation of the aluminum tube, and the staff can tilt the tray base 3 to pour out the sterilized aluminum tube placed on the tray base 3. With the above structure, the fixation of the aluminum tube can be released by pressing the second handle 32, and the aluminum tube placed on the tray base 3 can be poured out quickly, avoiding affecting the work efficiency of the staff.

[0033] The working principle of the technical solution provided by this invention is as follows: In use, the operator first presses the tray plate 26 towards the bottom of the tray base 3. At this time, the tray base 3 will cause the four first sliding plates 24 to slide synchronously along the outer walls of the four sliding cylinders 38 towards the bottom of the tray base 3. Simultaneously, the tension spring 39 will be stressed and deform along its bending direction. During this process, the two sides of the first sliding plates 24 will respectively abut against the inclined surfaces of the two limiting blocks 22. The limiting blocks 22 will then cause the limiting plates 20 to slide along the inner wall of the first clearance groove 4 towards the first sliding groove 18. The sliding cylinder 19 will slide synchronously along the inner wall of the first sliding groove 18 under the influence of the limiting plates 20. The spring 21 will be stressed and deform along its bending direction. The direction of deformation occurs until the first sliding plate 24 no longer abuts against the inclined surface of the limiting block 22. At this time, the spring 21 is no longer under force and recovers its deformation along its bending direction, and drives the limiting plate 20 to slide along the inner wall of the first clearance groove 4 towards the central axis of the first clearance groove 4. At the same time, the sliding column 19 will slide synchronously along the inner wall of the first sliding groove 18 under the action of the limiting plate 20. The limiting block 22 will move synchronously towards the central axis of the first clearance groove 4 under the action of the limiting plate 20. At this time, the top outer wall of the first sliding plate 24 will abut against the bottom outer wall of the limiting block 22. In this way, the first sliding plate 24 will be limited by the limiting block 22, so that the tension spring 39 remains in a deformed state.

[0034] At the same time, the third abutment block 30 will move synchronously with the tray 26. At this time, the inclined surface at the bottom of the third abutment block 30 will abut against the outer wall of the first abutment block 16. As the third abutment block 30 abuts, the originally inclined support plate 11 will rotate on the movable buckle 10 under the drive of the first abutment block 16 and remain perpendicular to the tray base 3. During this process, the first elastic plate 12, the clamping plate 13 and the second guide plate 14 will move synchronously with the movable buckle 10, and the second elastic plate 17 will be subjected to force and deform along its bending direction. Subsequently, the staff placed the cap of the aluminum tube in the gap between the two first partition plates 8. The cap of the aluminum tube slid down between the two clamping plates 13 under the guidance of the two second guide plates 14. The clamping plates 13 were tilted by the pressure of the cap of the aluminum tube. During this process, the first elastic plate 12 was subjected to force and underwent elastic deformation along its own bending direction. At the same time, under the elasticity of the two first elastic plates 12, the corresponding clamping plates 13 were driven to clamp the cap of the aluminum tube, and the anti-slip groove 15 was used to clamp and fix the aluminum tube.

[0035] After the aluminum tube is sterilized, the worker grasps the first handle 6 and hooks the second handle 32 with their fingers, pulling the second handle 32 towards the first handle 6. At this time, the third elastic plate 31 will be stressed and deform along its bending direction, while the two second sliding plates 33 will move towards the first handle 6 under the action of the second handle 32. At this time, the fourth abutment block 36 will move synchronously under the action of the second sliding plate 33, and the inclined surface of the fourth abutment block 36 will abut against the inclined surface of the second abutment block 23. Under the push of the fourth abutment block 36, the second abutment block 23 will drive the limiting plate 20 to slide along the inner wall of the first clearance groove 4 towards the first sliding groove 18. At the same time, the limiting block 22 will move synchronously under the action of the limiting plate 20. At this time, the bottom outer wall of the limiting block 22 no longer abuts against the first sliding groove 18. The limiting effect on the tray 26 is released on the top outer wall of the first sliding plate 24. At this time, the tension spring 39 is no longer under force and returns to its original deformation along its bending direction, and drives the first sliding plate 24 to move towards the top of the first clearance groove 4. The tray 26 will move synchronously with the first sliding plate 24 towards the top of the tray base 3. The third abutment block 30 will move synchronously with the tray 26. At this time, the inclined surface at the bottom of the third abutment block 30 no longer abuts against the outer wall of the first abutment block 16. The second elastic plate 17 is no longer under force and returns to its original deformation along its bending direction, and drives the support plate 11 to reset. In this way, the fixation on the aluminum tube can be released. During this process, the tray 26 will lift the aluminum tube, and the staff can tilt the tray base 3 to pour out the sterilized aluminum tube placed on the tray base 3.
