[0001] This application relates to the technical field of drug drying, and specifically to a drying device for a pharmaceutical tablet production workshop. Background Art

[0002] During the production and manufacturing of pharmaceutical tablets, a drying device is required to remove the moisture in the pharmaceutical tablets to keep them dry.

[0003] Chinese Patent Grant Publication No.: CN218329123U provides a drying oven for pharmaceutical granules. This solution uses an electric heating wire to increase the temperature of the granule drying oven to heat the pharmaceutical granules and dry the moisture inside. After heating and drying for a certain period of time, an electric push rod is used to push and adjust the rotating plate, so that the adjusting rotating plate moves on the fixed connecting plate and moves into the medicine placement box, thereby flipping the pharmaceutical granules to heat and dry the surface thereof, so that the surface of the pharmaceutical granules is evenly heated, and thus the speed of heating and drying the pharmaceutical granules is increased.

[0004] However, this solution requires the user to place the medicine separately in multiple particle holes, and the number of medicines it can carry is extremely limited, which is not suitable for the drying work of a large batch of medicines.

[0024] In order to enable those skilled in the art of this technology to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0025] As Figures 1-3 shown, this application provides a drying device for a pharmaceutical tablet production workshop, including a bracket 1, a drying box 2 fixedly connected to the bracket 1, a feed hole 6 and a discharge hole 7 are respectively opened at the upper and lower ends of the drying box 2, and a drum 8 is rotatably connected to the inner end of the drying box 2. A servo motor 4 is installed at the outer end of the drying box 2, the output end of the servo motor 4 is fixedly connected to the drum 8, a plurality of baffles 9 are fixedly connected to the outer end of the drum 8, the plurality of baffles 9 are arranged at equal intervals in a ring shape, a plurality of air inlet holes 10 are opened at the outer end of the drum 8, a plurality of air outlet holes 3 are opened at the outer end of the drying box 2, a hot air blower 5 is installed on the bracket 1, the output end of the hot air blower 5 is fixedly connected to a hot air pipe 11, a feed box 12 is fixedly connected to the top of the drying box 2, the feed box 12 is communicated with the feed hole 6, and the length of the feed hole 6 is less than the length of the drum 8.

[0026] During the manufacturing process of pharmaceutical tablets, a drying device is required to remove moisture from the pharmaceutical tablets to keep them dry. In this solution, the user can place a large number of pharmaceutical tablets in the feed box 12. The pharmaceutical tablets can pass through the feed hole 6 to the inner cavity of the air outlet 3, and then fall onto the surface of the drum 8. The multiple baffles 9 divide the surface of the drum 8 into multiple areas of equal area. Starting the servo motor 4 can drive the drum 8 to rotate slowly in the inner cavity of the drying box 2, and then through continuous rotation, the pharmaceutical tablets in the feed box 12 can gradually fall between the multiple pairs of baffles 9, and the pharmaceutical tablets can be separated into multiple portions. Such a configuration makes it convenient for users to dry large quantities of medicines, saves a lot of time in placing medicines, and also avoids the situation where a large number of medicines are piled up together and the moisture cannot be discharged well. Since the length of the feed hole 6 is smaller than the length of the drum 8, the area between the two adjacent baffles 9 will not be filled with medicines, but a certain amount of free space will be left. In this way, during the continuous rotation of the drum 8, the medicines will roll back and forth between the two adjacent baffles 9, so that the outer surface of the medicines is evenly heated, avoiding the situation where one side of the medicines abuts against an object when the medicines are stationary and cannot be heated.

[0027] like Figure 2 and 4 As shown, the baffle 9 is set to be made of flexible material, and the outer end of the baffle 9 is in contact with the inner wall of the drying box 2, the hot air pipe 11 passes through the side walls of the drying box 2 and the drum 8 respectively and extends to the inner cavity of the drum 8, and the outer end of the hot air pipe 11 is provided with a plurality of through holes connected to the inner cavity, an electric push rod 14 is installed on the bracket 1, and the output end of the electric push rod 14 is fixedly connected to a blanking plate 13, the blanking plate 13 matches the discharge hole 7, and the length of the discharge hole 7 matches the length of the drum 8.

[0028] During the rotation of the drum 8, the user can start the hot air blower 5, which injects hot air into the hot air pipe 11. The hot air enters the inner cavity of the drum 8 through the multiple through holes at the outer end of the hot air pipe 11, and then passes through the multiple air inlet holes 10 to enter the area between the drying box 2 and the drum 8, and then fully contacts the medicine to make the medicine fully heated. The excess hot air can be discharged outward through the air outlet 3 along with the water vapor emitted after the medicine is dried. The baffle 9 is set to a flexible material to reduce the damage to the medicine caused by the extrusion of the baffle 9. After the drying is completed, the user starts the electric push rod 14 to drive the unloading plate 13 to move downward, so that the unloading plate 13 is separated from the discharge hole 7. Since the length of the discharge hole 7 matches the length of the drum 8, as the drum 8 continues to rotate, the medicine therein will gradually be discharged through the discharge hole 7, thereby realizing the one-time loading and unloading of large quantities of medicines. The apertures of the air inlet hole 10 and the air outlet hole 3 are both set to be extremely narrow, allowing only hot air and water vapor to pass through, and the medicine will not fall into them.

[0029] Working principle:

[0030] During use, the user uniformly places a large quantity of pharmaceutical tablets into the feed box 12. The drugs come to the inner cavity of the air outlet hole 3 through the feed hole 6, and then fall onto the surface of the drum 8. The user starts the servo motor 4 to drive the drum 8 to slowly rotate in the inner cavity of the drying box 2. Through the continuous rotation of the drum 8, the drugs in the feed box 12 gradually fall between multiple pairs of baffles 9, gradually separating the drugs into multiple portions, and causing the drugs to roll back and forth between two adjacent baffles 9. At the same time, the user starts the hot air blower 5, and the hot air blower 5 injects hot air into the hot air pipe 11. Through multiple through holes at the outer end of the hot air pipe 11, the hot air enters the inner cavity of the drum 8, and then enters the area between the drying box 2 and the drum 8 through multiple air inlet holes 10, and then fully contacts the drugs, causing the drugs to be fully heated. The excess hot air, along with the water vapor emitted after the drugs are dried, can be discharged outward through the air outlet hole 3. After the drying is completed, the user starts the electric push rod 14 to drive the blanking plate 13 to move downward, so that the blanking plate 13 is separated from the discharge hole 7. Since the length of the discharge hole 7 matches the length of the drum 8, as the drum 8 continues to rotate, the drugs therein will gradually be completely discharged through the discharge hole 7, thus realizing the one-time feeding and one-time discharging of a large quantity of drugs.

[0031] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
