Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pharmaceutical intermediate processing, and particularly relates to a drying device for pharmaceutical intermediate processing. Background Technique
[0002] A pharmaceutical intermediate refers to a compound generated during the drug synthesis process that has not yet been converted into the final drug. They usually play a key role in the synthesis pathway and are precursors or components of the final drug molecule. To ensure the purity and reactivity of the pharmaceutical intermediate and avoid negative impacts on the efficacy and safety of the final drug, it is necessary to perform drying treatment on it to remove excess solvents or moisture.
[0003] The commonly used drying method in the prior art is to bake by heating until the moisture is completely evaporated. However, this method has certain limitations, mainly that it cannot ensure uniform heating of the pharmaceutical intermediate and uniform evaporation of moisture, which leads to caking of the pharmaceutical intermediate, thus having an adverse impact on the quality and yield of the final product. Therefore, the prior art needs to be further optimized to improve the uniformity and efficiency of the drying process. Content of the Utility Model
[0004] The purpose of the utility model is to provide a drying device for pharmaceutical intermediate processing to solve the problems existing in the prior art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is a drying device for pharmaceutical intermediate processing, including a bottom platform. Above the bottom platform, there is a motor. Above the motor, there is a processing tray. Inside the processing tray, there are heating wires. Above the heating wires, there is a partition plate. Above the bottom platform, multiple hydraulic cylinders are symmetrically arranged with the motor as the center. One end of the hydraulic cylinder away from the bottom platform is provided with a connecting plate. On the connecting plate, a processing box is arranged through a connecting column. The inside of the processing box is a cavity and the bottom of the processing box is in an open state. On the inner side wall of the processing box, there are multiple large fans. Above the processing box, there is an inclined feeding bin. The inside of the feeding bin is communicated with the processing box. A bin cover is arranged on the feeding bin.
[0006] Preferably, a filter screen is arranged at the opening above the feeding bin, and an exhaust fan is arranged inside the filter screen.
[0007] Preferably, an embedding plate is arranged on the bottom platform, and an embedding groove is opened on the embedding plate. The bottom of the processing box is adapted to the embedding groove.
[0008] Preferably, multiple temperature sensors are arranged on the inner side wall of the processing box.
[0009] Preferably, moving wheels are arranged below the bottom platform.
[0010] Preferably, a control panel is provided on the outer side wall of the processing box.
[0011] Compared with the prior art, the advantages and positive effects of the present utility model are that
[0012] In the present utility model, the heating wires are distributed along the processing tray. By driving the processing tray to rotate through a motor, the heating wires can uniformly heat the entire partition plate. The uniform heating temperature can prevent some areas from overheating or overcooling, thereby avoiding the problem of uneven temperature during the heating of the pharmaceutical intermediate. This helps to avoid the decomposition or caking of the pharmaceutical intermediate caused by local overheating, thereby improving the quality of the final product. The rotation of the processing tray causes the pharmaceutical intermediate to continuously turn over during the heating process. This turning effect ensures the uniform heating of the material. The continuous turning of the material helps to avoid the pharmaceutical intermediate from staying fixed on the processing tray and forming caking. In this way, not only can the material be heated more uniformly, but also the evaporation speed of water can be accelerated because the turned-over material is exposed to the heating source for a longer time and the area in contact with the hot air increases. The rotating processing tray causes the material to continuously change its position during the heating process, thereby reducing the adhesion and caking opportunities between the materials. Reducing the caking phenomenon can improve the processing efficiency of the pharmaceutical intermediate, prevent uneven heating of the material caused by caking during the processing, and thus ensure the purity of the pharmaceutical intermediate and improve the quality of the final product. Through this design, the cooperation between the rotation of the processing tray and the heating wires can significantly improve the drying uniformity of the pharmaceutical intermediate, reduce the caking phenomenon, thereby improving the efficiency of the overall production process and the quality of the final product, and ultimately improving the purity and production efficiency of the pharmaceutical intermediate.

Specific embodiments
[0020] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0022] Embodiment 1, as Figures 1-5As shown in the figure, the specific design of the above-mentioned key components will be described in detail below: A drying device for processing pharmaceutical intermediates includes a bottom platform 1. Above the bottom platform 1 is a motor 12. Above the motor 12 is a processing tray 13. Inside the processing tray 13 is a heating wire 15. Above the heating wire 15 is a partition 14. Above the bottom platform 1, a plurality of hydraulic cylinders 3 are symmetrically arranged with the motor 12 as the center. One end of the hydraulic cylinder 3 away from the bottom platform 1 is provided with a connecting plate 4. On the connecting plate 4, a processing box 6 is provided through a connecting column. The inside of the processing box 6 is a cavity and the bottom of the processing box 6 is in an open state. A plurality of large fans 16 are arranged on the inner side wall of the processing box 6. Above the processing box 6 is an inclined feed bin 7. The inside of the feed bin 7 is communicated with the processing box 6. A bin cover 8 is arranged on the feed bin 7. The heating wire 15 is arranged in the processing tray 13 and is driven by the motor 12 to rotate the processing tray 13. This configuration ensures that the heating wire 15 can uniformly heat the partition 14 on the processing tray 13 and then uniformly apply heat to the material. During the rotation process, the heat transfer from the heating wire 15 to the material is more sufficient, avoiding the problem of uneven local heating. The partition 14 is arranged above the heating wire 15 to make the heat generated by the heating wire 15 form a uniform heat flow above the partition 14. The partition 14 can prevent the heating wire 15 from directly contacting the material, thus avoiding the direct impact of excessive heating on the material and also helping to make the heat more evenly distributed on the entire surface of the material. A plurality of hydraulic cylinders 3 are symmetrically arranged on the bottom platform 1 to support and adjust the height position of the processing box 6, ensuring an internal sealing effect during the heating process of the material, improving the uniformity of heating temperature, and also being able to lift the processing box 6 under the action of the hydraulic cylinders 3 to facilitate the removal of the material above the processing tray 13. The inside of the processing box 6 is a cavity and the bottom is in an open state, designed to form a sealed chamber, facilitating covering the processing tray 13 and enhancing the overall heating effect. Through the setting of the embedding groove 11, the bottom of the processing box 6 just fits into the embedding groove 11 to form a sealed space, while avoiding the problem of the open bottom. A plurality of large fans 16 are installed on the inner side wall of the processing box 6, which are responsible for circulating hot air in the processing box 6, ensuring that the material can obtain uniform heat during the heating process and promoting the evaporation of moisture. The feed bin 7 is inclined to facilitate the inflow of the material into the processing box 6. The bin cover 8 can prevent external impurities from entering. Through the uniform arrangement of the heating wire 15 and the rotation of the processing tray 13, the heating wire 15 can uniformly heat the entire partition 14, enabling the material to obtain uniform heat. This uniform heating reduces the decomposition or caking phenomena in the material due to uneven temperature. The rotating processing tray 13 continuously tumbles the material, thus preventing the material from being fixed and caking during the heating process. The tumbling effect increases the contact area between the material and hot air, improves the evaporation rate of moisture, and reduces the chance of caking. The continuous tumbling of the material can not only prevent caking but also improve the evaporation rate of moisture, making the processing process more efficient. The uniform heating and efficient moisture evaporation together improve the processing efficiency of the pharmaceutical intermediate.Due to uniform heating, reduced caking, and improved processing efficiency, the purity and quality of the final product are enhanced. The stable production process ensures the consistency of the pharmaceutical intermediate, thereby improving the quality of the final product. In short, this design optimizes the cooperation between heating and the fan to ensure uniform heating and efficient processing of the material, thus improving production efficiency while ensuring the quality of the pharmaceutical intermediate, with significant practical value.
[0023] To enhance the overall structural flexibility and convenience, a filter screen 10 is provided at the opening above the feeding bin 7. An exhaust fan 18 is arranged inside the filter screen 10. The filter screen 10 serves to filter debris. An embedding plate 5 is provided on the bottom platform 1, and an embedding groove 11 is formed on the embedding plate 5. The bottom of the processing box 6 is adapted to the embedding groove 11. A plurality of temperature sensors 17 are arranged on the inner side wall of the processing box 6. Moving wheels 2 are provided below the bottom platform 1. A control panel 9 is arranged on the outer side wall of the processing box 6. The material flows from the feeding bin 7 into the processing box 6 under the action of gravity, which helps to improve the efficiency of material processing. The feeding bin 7 not only facilitates the discharge of the material but also helps to centrally discharge the hot air in the processing box 6. Opening the cover 8 allows the hot air in the processing box 6 to be discharged from the feeding bin 7, preparing for subsequent processing steps. The exhaust fan 18 inside the filter screen 10 can help improve the fluidity of the hot air and accelerate the discharge of heat from the processing box 6 through the feeding bin 7. The design of the embedding plate 5 and the embedding groove 11 on the bottom platform 1 enables the bottom of the processing box 6 to be fittingly embedded in the embedding groove 11. The embedding groove 11 can ensure the stability of the processing box 6 on the platform, preventing it from moving or tilting. The stable installation reduces potential safety hazards during operation, ensures the safety of the equipment and the material processing process, and guarantees the bottom seal of the processing box 6, improving the uniformity of the hot air inside the processing box 6. The temperature sensors 17 are installed on the inner side wall of the processing box 6 to monitor the temperature changes during the processing in real time, helping the operator understand the processing environment. The provision of the moving wheels 2 enables the entire processing device to be conveniently moved. The control panel 9 is used to operate and control the entire system, including functions such as the fan and temperature regulation, controlling and monitoring the various functions of the equipment, and improving the overall operation efficiency. The core advantage of this design lies in improving the stability, efficiency, and safety of material processing. The large fan 16 improves air fluidity and temperature control, the embedding groove 11 provides stable support, the temperature sensors 17 provide real-time monitoring, the moving wheels 2 increase the flexibility of the equipment, and the control panel 9 simplifies the operation process. Overall, this design provides an effective, flexible, and safe solution for material processing.
