Description

Technical Field

[0001] The utility model relates to the technical field of tablet medicine granulation, and more specifically to a tablet granulation drying device. Background Art

[0002] Tablet granulation is the process of adding appropriate excipients to drug raw materials in the form of powder, block, etc., and then making them into granular materials with a certain particle size and fluidity through mixing, granulation and other processes. A certain amount of binder or wetting agent is usually added during the granulation process, which will cause the granules to contain more water. If not dried, the moisture may cause chemical changes in the drug, such as hydrolysis and oxidation, during subsequent storage and processing, thereby affecting the stability and efficacy of the drug. Therefore, a tablet granulation drying device is used for drying treatment in the production process. However, the existing tablet granulation drying device has low drug drying efficiency, which is not conducive to production.

[0003] In response to the above problems, regarding the technical problem that the existing tablet granulation and drying device has low drug drying efficiency and is not conducive to production, after a lot of searches, a tablet granulation and drying device with patent publication number CN221324943U was found, which belongs to the field of tablet drug granulation technology. The device is equipped with a drying bin, a guide plate and a nozzle. The granulated material is sent into the drying bin and flows along the guide plate. The nozzle is set at one end and the bottom of the guide plate. The nozzle at one end can blow the material away to reduce the accumulation of the material. The nozzle at one end can cooperate with the nozzle at the bottom of the guide plate to dry the blown material.

[0004] However, the aforementioned tablet granulation and drying device still has some problems. For example, when the material is granulated into tablets and falls onto the moving guide plate, the tablets are still undried. When the airflow from the nozzle hits the undried tablets, the tablets can easily be blown away. To address these problems, the present invention provides a tablet granulation and drying device.

[0023] The following is a combination of the appended examples of the present invention Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0024] See also Figure 1-4 In the embodiment of the present invention, a tablet granulation and drying device includes a device body 1, a granulation mechanism 7, a feed port 2 and a discharge port 3, a belt transmission mechanism 8, which is arranged inside the device body 1 relative to the granulation mechanism 7, and a fixed box 17 is fixedly connected to the belt transmission mechanism 8 in the device body 1. The fixed box 17 is a hollow structure with an opening at one end facing the belt transmission mechanism 8. A heating plate 18 is provided at the opening of the fixed box 17. The heating plate 18 is arranged adjacent to and parallel to the belt transmission mechanism 8. An air inlet 16 and an air outlet 13 are penetrated at both ends of the fixed box 17. A fan 10 is fixedly connected, and the air outlet of the fan 10 is connected to the air inlet 16. The first fixed plate 14 is fixed in an inclined shape in the device body 1. The first fixed plate 14 is located at the bottom of the discharge end of the belt transmission mechanism 8. A guide plate 12 with an arc-shaped structure is fixedly connected to the first fixed plate 14. The end of the guide plate 12 facing away from the first fixed plate 14 is fixedly connected to the fixed box 17 at the top of the exhaust port 13. The arc groove of the guide plate 12 faces the gap between the discharge end of the belt transmission mechanism 8 and the guide plate 12. The end of the first fixed plate 14 facing away from the guide plate 12 is connected to the discharge port 3.

[0025] Specifically, the heating rod is extended along the transmission direction of the belt transmission mechanism 8. When the material enters the granulating mechanism 7 from the feed port 2, the granulating mechanism 7 granulates the material. The granulated material falls on the belt transmission mechanism 8. At this time, the heating plate 18 is heated, and the temperature reaches a preset value. As the belt transmission mechanism 8 moves, the tablets flow through the bottom of the heating plate 18 for drying and fall onto the first fixed plate 14 along the discharge end of the belt transmission mechanism 8. At the same time, the fan 10 in the device body 1 is started, and the air is sucked in from the outside and sent to the air inlet 16 of the fixed box 17 through the air outlet. The air passes through the fixed box 17 and opens. The heating plate 18 at the opening is heated to form hot air, which is blown out from the exhaust port 13 of the fixed box 17 to the guide plate 12. Since the two ends of the guide plate 12 are respectively connected to the first fixed plate 14 and the exhaust port 13, the hot air will pass through the guide plate 12 and blow toward the first fixed plate 14, thereby dispersing and further heating the fallen tablets. The tablets on the first fixed plate 14 are finally discharged to the discharge port 3. The overall structure is simple to operate. The hot air generated by the heating plate 18 and the fan 10 is used to dry the tablets to avoid damage to the tablets before they are formed, thereby improving the drying efficiency of the tablets.

[0026] It should be noted that the installation and operation methods of the device body 1, the granulating mechanism 7, the feed port 2 and the discharge port 3, and the belt transmission mechanism 8 can refer to the patent document of a tablet granulating and drying device with patent announcement number CN221324943U. At the same time, in order to prevent the fan 10 from taking away a large amount of heat generated by the heating plate 18, the temperature of the heating plate 18 can be appropriately increased or multiple heating plates 18 can be installed so that the tablets on the belt transmission mechanism 8 can reach the required temperature for drying, while ensuring that sufficient hot air is discharged from the exhaust port 13 to further air-dry the tablets. In this embodiment, the installation method and circuit connection of the heating plate 18 are prior art.

[0027] In the embodiment of the present utility model, Figure 3 and Figure 4 As shown, a partition 15 is fixedly connected to the fixed box 17, and the partition 15 has an end face inclined along the direction from the air inlet 16 to the air outlet 13, so that a cavity with a gradually decreasing cross-sectional area from the air inlet 16 to the air outlet 13 is formed between the partition 15 and the heating plate 18, and the diameter of the air inlet 16 is larger than the diameter of the air outlet 13. Specifically, such a design makes the flow rate of the hot air in the fixed box 17 gradually accelerate, thereby enhancing the drying effect on the material. The hot air enters the larger cross-sectional area area from the air inlet 16, and as it flows toward the air outlet 13, the cross-sectional area gradually decreases, and the wind speed increases, thereby improving the heat exchange efficiency between the hot air and the material.

[0028] In the embodiment of the present utility model, Figure 1As shown, an air inlet 5 connected to the fan 10 is provided through the device body 1. Specifically, the air inlet 5 provides an air source for the fan 10. The fan 10 sucks in external air and sends it into the air inlet 16 of the fixed box 17 through a pipeline.

[0029] In the embodiment of the present utility model, Figure 3 As shown, it also includes a scraper 11, which is arranged at the discharge end of the belt transmission mechanism 8. The scraper 11 is fixedly connected to the device body 1. The scraper 11 has an inclined surface inclined toward the first fixed plate 14. Specifically, when the tablets on the belt transmission mechanism 8 reach the discharge end, the scraper 11 can scrape off the tablets adhered to the belt and make them fall onto the first fixed plate 14 along the inclined surface, thereby avoiding tablets from remaining on the belt and improving the material collection efficiency.

[0030] In the embodiment of the present utility model, Figure 3 As shown, a support block 19 is fixedly connected to one end of the device body 1 facing the first fixed plate 14 away from the guide plate 12. A second fixed plate 22 fixedly connected to the support block 19 is provided between the first fixed plate 14 and the discharge port 3. The second fixed plate 22 is connected to the discharge port 3. The second fixed plate 22 is tilted from the support block 19 to the discharge port 3. The inclination direction of the second fixed plate 22 is opposite to that of the first fixed plate 14. The support block 19 is provided with a concave drainage groove 20 at the discharge end of the first fixed plate 14. The bottom of the drainage groove 20 is connected to the top of the second fixed plate 22. As shown in the figure, a plurality of The filter holes 9 and the receiving grooves 21 are fixedly connected to the device body 1 opposite to the multiple filter holes 9. Specifically, when the tablets on the first fixed plate 14 fall onto the second fixed plate 22 and are discharged to the discharge port 3, the drainage groove 20 can play a guiding role, so that the material falls accurately on the second fixed plate 22, avoiding the scattering of the material and ensuring the orderly flow of the material. At the same time, it can also guide the airflow on the first fixed plate 14; secondly, during the sliding process of the material on the second fixed plate 22, there may be some fine particles or impurities, which can fall into the receiving grooves 21 through the filter holes 9, thereby realizing the preliminary filtration of the material and improving the product quality.

[0031] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, a control mechanism 6 for controlling the heating plate 18, the belt transmission mechanism 8, the fan 10 and the granulating mechanism 7 is fixedly connected to the outside of the device body 1, and a mounting plate 4 is detachably connected to the device body 1. Specifically, the control mechanism 6 can adjust the temperature of the heating plate 18, the speed of the belt transmission mechanism 8, the air volume of the fan 10 and other parameters as needed to achieve precise control of the drying process. The detachable design of the mounting plate 4 facilitates maintenance and overhaul of the device. It should be noted that the method of connecting the control mechanism 6 to the above-mentioned structure is a prior art.

[0032] Working principle: The heating rod is extended along the transmission direction of the belt transmission mechanism 8. When the material enters the granulating mechanism 7 from the feed port 2, the granulating mechanism 7 granulates the material. The granulated material falls on the belt transmission mechanism 8. At this time, the heating plate 18 is heated, and the temperature reaches the preset value. As the belt transmission mechanism 8 moves, the tablets flow through the bottom of the heating plate 18 for drying, and fall onto the first fixed plate 14 along the discharge end of the belt transmission mechanism 8. At the same time, the fan 10 in the device body 1 is started, and the air is sucked in from the outside and sent to the air inlet 16 of the fixed box 17 through the air outlet. The air is heated when passing through the heating plate 18 at the opening of the fixed box 17 to form hot air, which is blown out from the exhaust port 13 of the fixed box 17 to the guide plate 12. The two ends of the plate 12 are respectively connected to the first fixed plate 14 and the exhaust port 13, so the hot air will pass through the guide plate 12 and blow toward the first fixed plate 14, thereby dispersing and further heating the fallen tablets. Subsequently, the tablets on the first fixed plate 14 fall onto the second fixed plate 22 and are discharged toward the discharge port 3. The drainage groove 20 can play a guiding role, so that the material falls accurately on the second fixed plate 22. During the sliding process of the material on the second fixed plate 22, there may be some fine particles or impurities. These particles and impurities can fall into the receiving groove 21 through the filter hole 9. The overall operation is simple. The hot air generated by the heating plate 18 and the fan 10 is used to dry the tablets to avoid damage to the tablets before they are formed, thereby improving the drying efficiency of the tablets.
