Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical technology, and specifically relates to an electric heating drying oven for pharmaceutical experiments. Background Technology

[0002] Electric heating drying ovens are drying equipment widely used in various fields such as chemical, pharmaceutical, electronics, and food industries. Their working principle involves using heat provided by electric heating elements to circulate hot air through a blower, drying materials at a constant temperature. In the pharmaceutical field, they are mainly used for dry heat sterilization of pharmaceutical packaging materials, drying of agricultural and sideline products, and drying of laboratory samples. They are a highly practical and efficient drying device.

[0003] Existing drying ovens have a single blowing method and poor air circulation. When medicines are piled up inside the drying oven, the airflow generated by ordinary centrifugal fans cannot penetrate the piled-up medicine layer, making it impossible for the moisture inside the medicine to be discharged in time. Medicines piled up at the bottom or inside are prone to incomplete drying, resulting in uneven drying and failing to meet the strict requirements of pharmaceutical experiments for consistent drying effects.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention is an electric heating drying oven for pharmaceutical experiments, including a drying oven, a blower assembly installed on the drying oven, a rotating assembly installed inside the drying oven, and multiple ventilation components evenly installed on the rotating assembly. The blower assembly is used to transport hot air into the inner cavity of the drying oven, and a portion of the hot air is transported to the ventilation components through the rotating assembly and then enters the inner cavity of the drying oven through the ventilation components. The rotating assembly can drive the ventilation components to rotate.

[0006] The blower assembly includes a blower device, which is installed on the top surface of the drying chamber. A connecting elbow is installed on the blower device, and a ventilation box is installed at one end of the connecting elbow. Both ends of the bottom surface of the ventilation box are equipped with air supply pipes that communicate with the interior of the box. The lower end of the air supply pipes communicates with the interior of the drying chamber. A connecting pipe that communicates with the interior of the ventilation box is also installed on the bottom surface of the ventilation box. The connecting pipe communicates with the inner cavity of the rotating assembly.

[0007] The rotating assembly includes a rotating tube, the upper end of which is rotatably mounted on the top surface of the drying chamber. A connecting pipe is rotatably mounted on the upper end of the rotating tube and communicates with its interior. Ventilation components are evenly inclined and mounted on the outer circumference of the rotating tube.

[0008] The ventilation system includes a main duct, which is inclinedly set on the outer circumference of the rotating pipe and communicates with its interior. Multiple secondary ducts are staggered on the main duct. Both the ends of the main duct and the ends of the secondary ducts are inlaid with spheres. More than 1 / 2 of the sphere is located inside the main duct or secondary duct, and the diameter of the opening end face of the main duct and the secondary duct is smaller than the diameter of the sphere.

[0009] A driven gear is coaxially mounted on the upper end of the rotating tube, and a drive device is installed on the top surface of the drying chamber. The drive end of the drive device is equipped with a driving gear, which meshes with the driven gear.

[0010] A feed hopper is provided at the top of the outer periphery of the drying oven. The feed hopper is connected to the inner cavity of the drying oven. A cover plate is provided at the opening of the feed hopper, which can completely cover the opening of the feed hopper.

[0011] The bottom of the outer perimeter of the drying chamber is equipped with an openable and closable discharge hopper door.

[0012] This utility model has the following beneficial effects: This invention can divert the hot air generated by the blower to the ventilation box via a connecting bend. Part of the hot air is evenly blown onto the surface of the medicine through the air supply pipe, while the other part is directly transported to the interior and lower layers of the medicine stack through the rotating pipe and main and auxiliary pipes. At the same time, the drive device drives the rotating pipe and its connected main and auxiliary pipes to rotate continuously, dynamically agitating the medicine during the hot air delivery process. This breaks the heat blind zone caused by the static stacking of medicine in traditional drying ovens. Through the synergistic effect of hot air penetration and mechanical agitation, the medicine can achieve all-round, dead-angle-free drying while in motion, avoiding batch quality differences caused by incomplete drying, and fully meeting the stringent standards of consistency and accuracy of drying effect in pharmaceutical experiments.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] Please see Figure 1 , Figure 2 As shown: This embodiment provides an electric heating drying oven 1 for pharmaceutical experiments, including a drying oven 1, a blower assembly 2 installed on the drying oven 1, a rotating assembly 3 installed inside the drying oven 1, and multiple ventilation components 4 evenly installed on the rotating assembly 3. The blower assembly 2 is used to transport hot air into the inner cavity of the drying oven 1, and a portion of the hot air is transported to the ventilation components 4 through the rotating assembly 3 and then enters the inner cavity of the drying oven 1 through the ventilation components 4. The rotating assembly 3 can drive the ventilation components 4 to rotate.

[0018] After the medicine is placed inside the drying chamber 1, the blower assembly 2 is activated to heat the air into hot air, which is then continuously delivered into the inner cavity of the drying chamber 1. During the process of the hot air entering the drying chamber 1, part of the hot air directly acts on the medicine inside the chamber, while the other part enters the rotating assembly 3. The rotating assembly 3 can be driven to rotate, thereby driving the ventilation component 4 to rotate, which stirs the medicine inside the drying chamber 1, allowing the medicine to be dried in a dynamic state. At the same time, the hot air entering the rotating assembly 3 is transmitted to the ventilation component 4, which releases the hot air to various areas of the inner cavity of the drying chamber 1 at different angles and positions. This ensures that the hot air can fully and evenly contact all parts of the medicine, preventing the medicine that is not fully dried due to accumulation inside. It also accelerates the evaporation and discharge of moisture on the surface and inside the medicine, allowing the medicine to undergo more uniform and efficient drying treatment in the drying chamber 1, meeting the strict requirements of pharmaceutical experiments for the consistency of drying effects.

[0019] like Figures 1-3As shown, the blower assembly 2 includes a blower device 5, which is installed on the top surface of the drying chamber 1. A connecting bend 6 is installed on the blower device 5, and a ventilation box 7 is installed at one end of the connecting bend 6. Air supply pipes 8, which communicate with the interior of the ventilation box 7, are installed at both ends of the bottom surface of the ventilation box 7. The lower end of the air supply pipes 8 communicates with the interior of the drying chamber 1. A connecting pipe 9, which communicates with the interior of the ventilation box 7, is also installed on the bottom surface of the ventilation box 7. The connecting pipe 9 communicates with the inner cavity of the rotating assembly 3. By activating the blower device 5, hot air is generated and transmitted to the ventilation box 7 through the connecting bend 6. The ventilation box 7 can directly deliver a portion of the hot air to the inner cavity of the drying chamber 1 through the air supply pipes 8. In the process, another portion of hot air is delivered to the rotating component 3 through the connecting pipe 9, and then to the ventilation component 4 through the rotating component 3. Under the synergistic effect of the rotating component 3 and the ventilation component 4, this portion of hot air can penetrate deep into the interior and lower areas of the drug stack, and cooperate with the hot air delivered by the air supply pipe 8 to form a three-dimensional hot air circulation path. Even if the drugs are stacked, the hot air released by the rotating ventilation component 4 can continuously change direction and blow into the interior of the stacked drugs, accelerating the discharge of moisture inside the drugs and achieving uniform drying of the drugs. This solves the problem of incomplete drying of drugs caused by poor airflow circulation in the traditional drying oven 1.

[0020] like Figures 1-5 As shown, the rotating assembly 3 includes a rotating tube 10, the upper end of which is rotatably mounted on the top surface of the drying chamber 1. A connecting pipe 9 is rotatably mounted on the upper end of the rotating tube 10 and communicates with its interior. Ventilation components 4 are evenly inclined and mounted on the outer circumference of the rotating tube 10. A driven gear 14 is coaxially arranged on the upper end of the rotating tube 10. A driving device 15 is mounted on the top surface of the drying chamber 1. The driving device 15 includes, but is not limited to, a geared motor. A driving gear 16 is provided at the driving end of the driving device 15. The driving gear 16 meshes with the driven gear 14. When the driving device 15 is started, the driving gear 16 is driven to rotate, thereby causing the driven gear 14 to rotate. The rotating pipe 10 drives the ventilation component 4 on it to rotate evenly. A portion of the hot air generated by the blower 5 is delivered to the rotating pipe 10 through the connecting pipe 9. The hot air is then delivered to the ventilation component 4 through the rotating pipe 10, which in turn drives the ventilation component 4 to rotate, stirring the medicine inside the drying chamber 1 and allowing it to be dried in a dynamic state. At the same time, the ventilation component 4 can also deliver a portion of the hot air directly to the interior of the stacked medicine, avoiding the hot air only acting on the surface of the stacked medicine and allowing it to penetrate directly into the interior of the medicine, so that the medicine can be dried more evenly and efficiently in the drying chamber 1.

[0021] like Figure 1 , Figure 2 , Figure 4As shown, the ventilation component 4 includes a main pipe 11, which is inclinedly installed on the outer circumference of the rotating pipe 10 and communicates with its interior. The inclined installation can utilize the pressure of the hot air itself and the centrifugal force generated by the rotation to make the hot air flow quickly and smoothly in the main pipe 11. Multiple secondary pipes 12 are staggered on the main pipe 11. Both the ends of the main pipe 11 and the ends of the secondary pipes 12 are inlaid with spheres 13. More than 1 / 2 of the spheres 13 are located in the main pipe 11 or the secondary pipes 12, and the diameter of the opening end face of the main pipe 11 and the secondary pipes 12 is smaller than the diameter of the spheres 13. The hot air inside the main pipe 11 can be diverted to the multiple secondary pipes 12, so that the hot air is blown from the ends of the main pipe 11 and the secondary pipes 12 into the drying chamber 1 and directly penetrates into the medicine. The rotating and inlaid spheres 13 can block the medicine accumulated inside the drying chamber 1, preventing it from entering its inner cavity from the ends of the main pipe 11 or the secondary pipes 12 and affecting the blowing effect.

[0022] like Figure 1 , Figure 5 As shown, a feeding hopper 17 is provided at the top of the outer periphery of the drying chamber 1. The feeding hopper 17 communicates with the inner cavity of the drying chamber 1. A cover plate 18 is provided at the opening of the feeding hopper 17. The cover plate 18 can completely cover the opening of the feeding hopper 17. When the cover plate 18 is opened, the medicine can be poured into the inner cavity of the drying chamber 1 through the feeding hopper 17. After the medicine is added, the cover plate 18 is closed. The cover plate 18 can completely cover the opening of the feeding hopper 17, forming a good sealing effect, effectively preventing the hot air inside the drying chamber 1 from leaking out, maintaining a stable high-temperature environment inside the chamber and the normal operation of the hot air circulation system. At the same time, it also prevents external dust, moisture and other impurities from entering the chamber, avoiding contamination of the medicine and affecting the quality of the medicine.

[0023] like Figure 1 As shown, the bottom of the outer periphery of the drying chamber 1 is provided with an openable discharge chamber door 19. During the drying process, the discharge chamber door 19 is in a closed state, forming a good sealing structure to prevent hot air from leaking out of the drying chamber 1 and to prevent cold air, dust and other impurities from entering. After the medicine is dried, the discharge chamber door 19 is opened. Since the door is located at the bottom of the drying chamber 1, the medicine can slide directly from the drying chamber 1 into the external collection container under the action of gravity.

[0024] The working principle of the electric heating drying oven 1 for pharmaceutical experiments provided by this utility model is as follows: Medicines are poured into the drying oven 1 through the feed hopper 17. Then, the blower 5 is activated to generate hot air. The hot air is transmitted to the ventilation box 7 through the connecting bend 6. The ventilation box 7 can directly deliver a portion of the hot air into the inner cavity of the drying oven 1 through the air supply pipe 8, and deliver another portion of the hot air to the inside of the rotating pipe 10 through the connecting pipe 9. The rotating pipe 10 then delivers the hot air to the main pipe 11 and the auxiliary pipe 12. Thus, the hot air is blown into the drying oven 1 from the ends of the main pipe 11 and the auxiliary pipe 12, allowing the portion of hot air entering the rotating pipe 10 to penetrate deep into the interior and lower part of the medicine stack. The layered area prevents the medicines accumulated inside from not being fully dried. The sphere 13 can block the medicines accumulated inside the drying chamber 1, preventing them from entering the inner cavity from the end of the main pipe 11 or the auxiliary pipe 12. After the drive device 15 is started, the meshing of the drive gear 16 and the driven gear 14 can drive the rotating tube 10 to rotate, so that the main pipe 11 and the auxiliary pipe 12 can follow the rotating tube 10 to rotate. This can agitate the medicines inside the drying chamber 1, so that they are dried in a moving state, which further improves the drying efficiency and achieves uniform drying of the medicines. This solves the problem of incomplete drying of medicines caused by poor airflow circulation in traditional drying chambers 1.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
