Abstract
Description
Technical Field
[0001] This utility model relates to the field of pill processing technology, and in particular to a rotary drying device for pills. Background Technology
[0002] As a common form of pharmaceutical preparation, pills are usually made by mixing powders and excipients and processing them into spherical or pellet shapes for easy carrying and administration by patients. They usually also require a hot air blower to provide drying treatment to remove moisture from the pills and ensure their long-term stability.
[0003] The pill drying process involves feeding the pills into a rotating chamber, closing the chamber, and then starting the rotation to allow the pills to tumble thoroughly. Simultaneously, a hot air blower heats the pills, evaporating the moisture and extending their shelf life. However, hot air drying is inherently unstable; pills closer to the hot air source may become over-dried, while those further away may not dry completely, affecting the overall drying effect and the quality of the pills. Utility Model Content
[0004] The technical problem this invention aims to solve is that traditional hot air drying can easily lead to uneven heating of pills, affecting the quality of the pill products.

A connecting rod is rotatably provided at the output end of the stirring chamber. Multiple electric heating plates are provided around the connecting rod. A feed inlet is connected to the top of one side of the silo, and a discharge outlet is connected to the bottom of the other side. A toothed ring is fixedly provided at the center of the silo.
[0007] The top two sides of the rotating frame are fixedly connected to annular rotating rails, and the bottom side of the rotating frame is fixedly connected to a rotating motor. The output end of the rotating motor is fixedly connected to a gear that meshes with a gear ring. The hopper is rotatably connected to the rotating frame through the annular rotating rails.
[0008] As a further improvement of this utility model, the top of the silo is connected to an exhaust duct, and a ventilation fan is fixedly connected to the inner wall of the exhaust duct. The exhaust duct is located at the top of the discharge port.
[0009] As a further improvement of this utility model, a purification filter plate is snapped into the bottom end of the exhaust duct, and the purification filter plate is located below the ventilation fan.
[0010] As a further improvement of this utility model, an air pipe mounting bracket is provided on the outer side of the exhaust duct.
[0011] As a further improvement of this utility model, a plurality of rotating grooves that are rotatably connected to the annular rotating track are fixedly arranged around the hopper body.
[0012] As a further improvement of this utility model, a plurality of guide posts are fixedly connected around the discharge port.
[0013] As a further improvement of this utility model, the connecting rod is fixedly connected with a guide vane.
[0014] As a further improvement of this utility model, the electric heating plate is alternately arranged around the guide vane and fixedly connected to the connecting rod.
[0015] As a further improvement of this utility model, the heating temperature of the electric heating plate decreases sequentially from the inlet side to the outlet side.
[0016] The beneficial effects of this invention are as follows: This invention uses electric heating plates distributed on the connecting rod to heat the pellets inside the chamber. The electric heating plates provide a stable heat source, effectively improving the heating efficiency of the pellets. Furthermore, the cooperation between the rotating motor and the mixing chamber ensures that the connecting rod and the chamber rotate evenly.

[0025] This utility model provides the following: Figure 1-4 As shown, a rotary drying device for pills includes a chamber 1 and a rotating frame 2;
[0026] The silo 1 is configured as a horizontal cylindrical structure. A stirring chamber 3 is fixedly connected to one side of the silo 1. A connecting rod is rotatably provided at the output end of the stirring chamber 3. Multiple electric heating plates 4 are provided around the connecting rod. A feed inlet is connected to the top of one side of the silo 1, and a discharge outlet is connected to the bottom. Both the feed inlet and the discharge outlet are provided with caps. A toothed ring 6 is fixedly provided on the center side of the silo 1.
[0027] The top two sides of the rotating frame 2 are fixedly connected to annular rotating rails 7, and multiple rotating grooves 13 that are rotatably connected to the annular rotating rails 7 are fixedly arranged around the hopper 1. The rotating grooves 13 help to ensure the stability of the rotation of the hopper 1 on the annular rotating rails 7. The bottom side of the rotating frame 2 is fixedly connected to a rotating motor 8, and the output end of the rotating motor 8 is fixedly connected to a gear that meshes with a gear ring 6. The hopper 1 is rotatably connected to the rotating frame 2 through the annular rotating rails 7.
[0028] like Figure 4 As shown, the top of the chamber 1 is connected to an exhaust duct 9, and a ventilation fan is fixedly connected to the inner wall of the exhaust duct 9. The exhaust duct 9 is located at the top of the discharge port. The exhaust duct 9 is used to discharge the reaction gas and odor inside the chamber 1. A purification filter plate 10 is snapped into the bottom of the exhaust duct 9. The purification filter plate 10 is located below the ventilation fan. The purification filter plate 10 is used to adsorb and purify the discharged gas.
[0029] like Figure 4As shown, an air pipe mounting bracket 11 is fitted on the outside of the exhaust duct 9; multiple mounting guide pillars 12 are fixedly connected around the discharge port; the air pipe mounting bracket 11 and the mounting guide pillars 12 facilitate the installation of the exhaust conveying pipe and the material receiving container, respectively.
[0030] like Figure 2 As shown, a guide vane 5 is fixedly connected to the connecting rod; the guide vane 5 serves as a guide for the discharge of the pills. Electric heating plates 4 are alternately arranged around the guide vanes 5 and fixedly connected to the connecting rod; this ensures sufficient contact with the pills. The heating temperature of the electric heating plates 4 decreases sequentially from the inlet side to the outlet side; this prevents the pills from being overheated.
[0031] Working principle: In the specific implementation of this utility model, the cover on the feed port side is removed, a certain amount of pills is placed into the chamber 1, and then the feed port is closed. The rotating motor 8 is started, so that the gear at the output end rotates slowly clockwise, causing the gear ring 6 to drive the chamber 1 to rotate on the rotating frame 2. At the same time, the rotating grooves 13 on both sides of the chamber 1 are guided by the annular rotating rail 7 to ensure the stability of the rotation of the chamber 1. The stirring chamber 3 drives the connecting rod to rotate slowly counterclockwise to ensure that the pills are heated evenly. Finally, the pills in the chamber 1 are moved to the discharge port side under the guidance of the guide vane 5. Then, the rotating motor 8 is stopped, the sealing plate on the discharge port side is removed, and the material receiving container is connected to the discharge port by the installation guide post 12. By driving the stirring chamber 3, the connecting rod drives the guide vane 5 to rotate out to the discharge side. At the same time, the exhaust conveying pipe is connected to the air pipe mounting bracket 11, and the ventilation fan on the inner wall of the exhaust duct 9 is started. After passing through the purification filter plate 10, the exhaust operation in the chamber 1 is completed.
