Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a pharmaceutical hot air circulating drying oven that is easy to handle. Background Technology

[0002] Drugs are substances used to prevent, treat, and diagnose diseases. During the drug manufacturing process, they undergo drying. The main reason for drying is to prevent the drugs from getting damp, maintaining their chemical properties, physical characteristics, packaging integrity, and efficacy stability. For some biological agents, such as insulin, moisture can lead to reduced efficacy or even inactivation. Therefore, maintaining dryness is crucial to ensuring the quality and safety of pharmaceuticals. Currently, there are various types of pharmaceutical hot air circulating drying ovens on the market, but some shortcomings still exist.

[0003] Existing pharmaceutical hot air circulating drying ovens dry drugs by placing them inside the oven. However, the dried drugs are difficult to remove from the oven, and a large amount of water vapor is generated during the drying process. Without treating the water vapor, the drying efficiency of the drugs will be affected. For example, Chinese utility model patent CN213147180U discloses a hot air circulating drying device for biopharmaceuticals, which includes a drying oven. Several support legs are fixedly connected to the bottom of the drying oven. Two load plates are provided inside the drying oven and are fixedly connected to the drying oven. Several ventilation holes are opened on the load plates. The bottom inner wall of the drying oven is equipped with a drying chamber, which is a cavity structure with an open top. This utility model describes a hot air circulating drying device for biopharmaceuticals, belonging to the technical field of drying ovens. It involves placing a desiccant inside the drying oven and heating the interior with heating wires to dry the medicinal materials. Simultaneously, air circulation within the oven reduces the water vapor content, improving drying efficiency and facilitating desiccant replacement for future use. A pull ring allows for easy movement of the fixed ring. However, this device, which involves placing the medicine inside and heating the interior with heating wires, can lead to uneven drying. Therefore, we propose a convenient hot air circulating drying oven for pharmaceuticals to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a convenient hot air circulating drying oven for pharmaceuticals, to solve the problems mentioned in the background art. In current hot air circulating drying ovens for pharmaceuticals, the drugs are dried by placing them inside the oven. After the drugs are dried, it is difficult to quickly remove them from the oven. At the same time, the drugs placed inside the oven have a certain thickness, and the heating wires heating the inside of the oven will result in uneven drying. In addition, water vapor is generated during the drying process, and without treating the water vapor, the drying efficiency will be greatly reduced.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical hot air circulating drying oven that is easy to handle, comprising:

[0006] The drying chamber body is placed directly on the ground;

[0007] Also includes:

[0008] A rotating shaft is provided with a convenient picking and placing mechanism on its outer side. The convenient picking and placing mechanism includes a connecting block, a sliding block, a filter box, a support plate, a rotating plate, and bolts. The connecting block is installed at equal angles on the outer side of the rotating shaft, and a sliding block is slidably connected inside the connecting block. The filter box is fixedly installed outside the sliding block, and the support plate is tightly attached to the bottom of the filter box.

[0009] A drying mechanism is provided inside the upper part of the drying oven body. The drying mechanism includes a filter frame, a filter tray, a handle, a threaded plate, and a fixing block. The filter frame is fixedly installed inside the upper part of the drying oven body, and the filter tray is slidably arranged inside the filter frame. A handle is installed on the front side of the middle part of the filter tray, and the threaded plate is symmetrically and tightly attached to the front side of the filter tray.

[0010] Preferably, a rotating shaft is rotatably mounted inside the drying oven body, and a first bevel gear is fixedly mounted above the rotating shaft.

[0011] Preferably, a second bevel gear is meshed with the right side of the first bevel gear, and a motor is connected to the right end of the second bevel gear.

[0012] Preferably, a rotating disk is fixedly connected to the lower part of the rotating shaft, and a spring is fixedly installed at an equal angle above the rotating disk, and a support plate is connected above the spring.

[0013] Preferably, a rotating plate is rotatably connected to the outer side of the support plate, and the rotating plate is attached to the lower outer side of the filter box, and the rotating plate and the filter box are fixedly connected by bolts.

[0014] Preferably, the outer side of the threaded plate is threaded with a fixing block, and the fixing block is symmetrically fixedly installed below the filter frame.

[0015] Preferably, the inner wall of the drying oven body is provided with heating wires, and the outer side of the drying oven body is equipped with an air duct, and an air pump is provided at the upper center of the air duct.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This convenient hot air circulating drying oven for pharmaceuticals is designed with a convenient loading and unloading mechanism, which makes it easy to place the medicine inside the oven and quickly remove it after drying, thus greatly improving the efficiency of medicine drying. At the same time, a rotating mechanism is provided to place the medicine into the filter box, which can rotate and vibrate, greatly improving the uniformity of medicine drying. In addition, a drying mechanism is provided to dry the water vapor generated during the medicine drying process, further improving the efficiency of medicine drying.

[0017] 1. The device comprises a drying chamber body, a rotating shaft, a connecting block, and a sliding block. The rotating shaft is rotatably mounted in the middle of the drying chamber body, and the connecting block is installed at equal angles on the outside of the rotating shaft. The inside of the connecting block is connected to the sliding block, which is located inside the filter box. The filter box contains the medicine to be dried. A first bevel gear is installed at the upper end of the rotating shaft, and the right side of the first bevel gear is meshed with a second bevel gear. When the motor connected to the right end of the second bevel gear is turned on, the second bevel gear can rotate. At this time, the first bevel gear and the rotating shaft will rotate together, and the filter box will also rotate. The medicine inside the filter box will move inside the filter box as it rotates, thereby achieving uniform drying of the medicine.

[0018] 2. The filter box is equipped with a support plate, a rotating plate, a spring, and a rotating disk. The support plate is tightly attached to the bottom of the filter box, and the rotating plate is rotatably connected to the outside of the support plate. The rotating plate is fixedly connected to the filter box with bolts. At the same time, a spring is set below the support plate, and the bottom of the spring is fixedly connected to the rotating disk. The rotating disk is fixedly set at the lower end of the rotating shaft. That is, when the rotating shaft rotates, the rotating disk will also rotate. In addition, the spring has elasticity. That is, when the filter box rotates, the sliding block and the connecting block installed inside the filter box are slidably connected. Under the action of inertia, the filter box will also vibrate up and down, which will further improve the uniformity of drug drying.

[0019] 3. It is equipped with a filter screen box, a rotating plate, and bolts. The rotating plate and the filter screen box are fixed together by bolts. At the same time, the sliding block installed inside the filter screen box is slidably connected to the connecting block. That is, after the medicine is dried, the bolts fixing the filter screen box and the rotating plate can be unscrewed and the filter screen box can be pulled out. Since the rotating plate is rotatably connected to the support plate attached to the bottom of the filter screen box, the rotating plate will detach from the filter screen box at this time. The filter screen box can be taken out from the front of the drying oven body. The top cover set on the top of the filter screen box can be opened, so that the medicine inside the filter screen box can be poured out.

[0020] 4. Equipped with a filter rack and filter drawer, the filter rack is fixedly installed inside the upper part of the drying chamber. The filter drawer is located inside the filter rack and can hold desiccant. When the air pump is started, it draws in hot air from inside the drying chamber, which enters from below the air duct and then from above, thus circulating the hot air. When the hot air enters the drying chamber from above, it passes through the desiccant in the filter drawer. The desiccant absorbs the water vapor in the hot air, greatly improving the drying efficiency of the medicine.

[0021] 5. Equipped with a handle, threaded plate, and fixing block, the filter tray is tightly fitted to the threaded plate on both the left and right sides of the front. The outer side of the threaded plate is threadedly connected to the fixing block fixedly installed below the filter frame. To replace the desiccant inside the filter tray, rotate the threaded plate to detach it from the fixing block, then pull it out of the fixing block. This separates the threaded plate from the filter tray. Then, pull the handle installed on the front side of the center of the threaded plate to pull the filter tray out of the filter frame, allowing you to replace the desiccant inside.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a convenient hot air circulating drying oven for pharmaceuticals, comprising a drying oven body 1; a convenient loading and unloading mechanism located on the outside of the rotating shaft 2, facilitating the removal of the filter box 5 from the interior of the drying oven body 1, and facilitating the handling of the medicine inside the filter box 5; and a rotating mechanism located inside the drying oven body 1, enabling the filter box 5 to rotate, thereby ensuring uniform drying of the medicine placed inside the filter box 5.The drying mechanism, located inside the upper part of the drying chamber body 1, absorbs the water vapor generated during drug drying, further improving the drying efficiency. First, open the front door of the drying chamber body 1, then open the top cover of the filter box 5. Pour the drug to be dried into the filter box 5. After pouring, close the top cover of the filter box 5 and the front door of the drying chamber body 1. Turn on the heating wire 19 inside the drying chamber body 1 to heat the interior. Then turn on the motor 13. Starting the motor 13 will cause the connected second bevel gear 12 to rotate. When the second bevel gear 12 rotates, the first bevel gear 11 meshing on the left will also rotate. Since the first bevel gear 11 is fixedly installed... Above the rotating shaft 2, and at equal angles on its outer side, a connecting block 3 is provided. The connecting block 3 is connected to a sliding block 4 installed inside the filter box 5. That is, when the first bevel gear 11 rotates, the rotating shaft 2 and the filter box 5 will also rotate. Since a rotating disk 10 is fixedly installed at the lower end of the rotating shaft 2, and a spring 9 is provided at equal angles above the rotating disk 10, the upper part of the spring 9 is fixedly connected to the support plate 6. The support plate 6 is tightly fitted to the lower part of the filter box 5. Furthermore, a rotating plate 7 is rotatably installed on the outer side of the support plate 6. The rotating plate 7 is fixedly connected to the filter box 5 by bolts 8. Because the spring 9 has elasticity, when the filter box 5 rotates, the spring 9 will vibrate up and down, meaning the filter box 5 can both rotate and... The system vibrates up and down to ensure even drying of the medicine inside the filter box 5. A filter frame 14 is installed above the drying chamber body 1, with a filter tray 15 slidingly mounted inside. A desiccant is placed inside the filter tray 15. When the air pump 21 is turned on, since it is located above the middle of the air duct 20, it draws hot air from inside the drying chamber body 1 into the lower part of the air duct 20, then back up to the upper part of the air duct 20 before entering the drying chamber body 1. This process repeats to circulate the hot air. Because the drying process generates water vapor, the hot air entering the drying chamber body 1 passes through the desiccant inside the filter tray 15, which absorbs the water vapor in the hot air. The filter tray 15 is designed to further improve the efficiency of drug drying. The front left and right sides of the filter tray 15 are tightly fitted with threaded plates 17. The threaded plates 17 are threadedly connected to the fixing blocks 18 installed below the filter frame 14. Rotating the threaded plates 17 disengages them from the fixing blocks 18, allowing the filter tray 15 to be pulled out by grasping the handle 16 on the front side of the middle section. This allows the filter tray 15 to be pulled out of the filter frame 14, replacing the desiccant inside. After the drug drying is complete, the bolts 8 securing the rotating plate 7 and the filter box 5 can be unscrewed, separating the rotating plate 7 and the filter box 5. The filter box 5 can then be removed from the drying chamber body 1, allowing the drug inside to be taken out.

[0032] Existing drying ovens dry the medication by placing it inside the oven. However, once the medication is dried, it is difficult to quickly remove the contents of the oven. Therefore, this embodiment addresses this issue by employing the following technical solution: Figure 4 , Figure 5 and Figure 6 As shown, the convenient loading and unloading mechanism includes a rotating shaft 2 located in the middle of the drying oven body 1. A connecting block 3 is installed at an equal angle on the outside of the rotating shaft 2. The inside of the connecting block 3 is slidably connected to a sliding block 4 fixedly installed on the rear side of the filter box 5. At the same time, a support plate 6 is tightly attached to the bottom of the filter box 5, and a rotating plate 7 is rotatably connected to the outside of the support plate 6. The rotating plate 7 is fixedly connected to the filter box 5 by bolts 8. That is, after the medicine is dried, the bolts 8 fixing the filter box 5 and the rotating plate 7 can be unscrewed and pulled out. Since the rotating plate 7 and the support plate 6 attached to the bottom of the filter box 5 are rotatably connected, the rotating plate 7 and the filter box 5 will detach at this time, and the filter box 5 can be taken out from the front side of the drying oven body 1. The top cover of the filter box 5 can be opened, so that the medicine inside the filter box 5 can be poured out.

[0033] Example 2: In existing drying ovens, the drugs placed inside the oven have a certain thickness, and the heating wire 19 heats the inside of the oven, resulting in uneven drying. Therefore, this example uses the following technical solution, such as... Figure 3 , Figure 5 and Figure 6 As shown, the rotating mechanism includes a rotating shaft 2 located in the middle of the drying chamber body 1. A connecting block 3 is mounted at an equal angle to the outside of the rotating shaft 2. The inside of the connecting block 3 is connected to a sliding block 4, which is located inside the filter box 5. The filter box 5 contains the medicine to be dried. A first bevel gear 11 is mounted on the upper end of the rotating shaft 2. The right side of the first bevel gear 11 is meshed with a second bevel gear 12. When the motor 13 connected to the right end of the second bevel gear 12 is turned on, the second bevel gear 12 can rotate. At this time, the first bevel gear 11 and the rotating shaft 2 will rotate together, causing the filter box 5 to rotate as well. The medicine inside the filter box 5 will then be circulated within the filter box 5. The filter box 5 is designed to move, allowing for uniform drying of the medicine. A support plate 6 is tightly fitted to the bottom of the filter box 5, and a rotating plate 7 is rotatably connected to the outside of the support plate 6. The rotating plate 7 is fixedly connected to the filter box 5 by bolts 8. A spring 9 is installed below the support plate 6, and its lower part is fixedly connected to a rotating disk 10. The rotating disk 10 is fixedly located at the lower end of the rotating shaft 2. Therefore, when the rotating shaft 2 rotates, the rotating disk 10 also rotates. Furthermore, the spring 9 has elasticity; that is, when the filter box 5 rotates, the sliding block 4 installed inside the filter box 5 is slidably connected to the connecting block 3, and under the action of inertia, the filter box 5 will also vibrate up and down, further improving the uniformity of medicine drying.

[0034] Example 3: Existing drying ovens generate water vapor during the drug drying process. Failure to treat this water vapor significantly reduces the drying efficiency. Therefore, this example addresses this issue by implementing the following technical solution: Figure 2 , Figure 3 and Figure 5 As shown, the drying mechanism includes a filter frame 14 disposed above the interior of the drying chamber body 1. A filter tray 15 is disposed inside the filter frame 14, and desiccant can be placed inside the filter tray 15. When the air pump 21 is started, it draws in hot air from inside the drying chamber body 1, which enters from below the air duct 20 and then from above the air duct 20, thus circulating the hot air. When the hot air enters the drying chamber body 1 from above, it passes through the desiccant placed inside the filter tray 15. The desiccant then reacts with the desiccant in the hot air... The filter absorbs water vapor, thereby greatly improving the drying efficiency of the drug. In addition, the front left and right sides of the filter tray 15 are tightly fitted with the threaded plate 17, and the outer side of the threaded plate 17 is threadedly connected to the fixing block 18 fixedly installed below the filter frame 14. That is, if the desiccant inside the filter tray 15 needs to be replaced, the threaded plate 17 can be rotated to disengage it from the fixing block 18, and the handle 16 installed on the front side of the middle of the threaded plate 17 can be pulled out of the filter frame 14 to replace the desiccant inside the filter tray 15.
