Description

Technical Field

[0001] The utility model relates to the technical field of powder production, in particular to a drying device for powder production. Background Art

[0002] Before the powder is processed into tablets, capsules, etc., it is necessary to dry the powder to reduce the moisture in the powder and avoid the deterioration of the powder. In the prior art, the powder is usually directly laid flat in the drying box, and there is a lack of turning of the powder during the drying process, so that the powder on the surface of the tray will be dried faster. That is, under the action of high temperature, the upper part of the powder in the tray is dried and caked first, while the lower part of the powder is not completely dried. This will lead to the problem that the dried powder in the upper part blocks the evaporation of moisture in the lower wet powder, thereby reducing the drying speed of the powder. At the same time, it may also cause the upper powder to be over-dried, resulting in the problem of powder denaturation. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As can be seen from the specification 1-5, the present application specifically designs a drying device for powder production, which improves the existing drying box body 1. A tray rack 2 is arranged in the drying box body 1. A rotating support member is arranged in layers on the tray rack 2. A fixed gear ring 3 is sleeved outside the rotating support member. A fixed shaft 4 is arranged on one side of the fixed gear ring 3. A driving gear 5 is installed on the fixed shaft 4. The driving gear 5 meshes with the fixed gear ring 3. The upper end of the fixed shaft 4 penetrates through the upper end face of the drying box body 1 and is connected to the driving mechanism 6. A tray card slot 7 is arranged on the rotating support member. A circular tray 8 is placed on the tray card slot 7. Guiding columns 9 are symmetrically arranged on both sides of the tray rack 2. A moving seat 10 is slidably installed on the guiding columns 9. A raking component is installed on the side of the moving seat 10. A lifting and adjusting structure is arranged on the top of the drying box body 1. The moving end of the lifting and adjusting structure extends into the drying box body 1 and is connected to the moving seat 10. Among them, the rotating support member includes an annular track 11, a rotating ring 12 and a supporting ring 13. The annular track 11 is arranged on the tray rack 2. The rotating ring 12 is rotationally matched with the annular track 11. The fixed gear ring 3 is welded to the outside of the rotating ring 12. The supporting ring 13 is assembled and connected to the rotating ring 12. The driving mechanism 6 can be used to drive the fixed shaft 4, and then the rotation adjustment of the circular tray 8 can be realized through the cooperation of the driving gear 5 and the fixed gear ring 3. The lifting and adjusting structure can realize the control and adjustment of the raking component in the height direction. The raking component is extended into the circular tray 8. While the drying box body 1 is drying and heating, the circular tray 8 is controlled to rotate, and the raking component is used to rake the powdery medicine raw materials in the circular tray 8, so as to improve the uniformity and drying efficiency of the powder drying, and thus solve the problems that the medicine powder is dried unevenly and the upper medicine powder may be over-dried in the prior art.

[0019] In the specific implementation process, as a preferred setting, the above-mentioned lifting and adjusting structure includes an upright frame 14, a cylinder 15, a cross beam 16 and a guiding member. The upright frame 14 is arranged on the drying box body 1. The cylinder 15 is arranged on the upright frame 14 in the vertical direction. The cross beam 16 is installed on the telescopic end of the cylinder 15. The guiding members are symmetrically arranged on both sides of the cylinder 15 and one end of each guiding member is connected to the cross beam 16. The guiding member includes a guiding sleeve 17 and a sliding rod 18. Through holes are symmetrically formed in the top of the drying box and penetrate through it. The guiding sleeve 17 is embedded in the through hole. The sliding rod 18 is slidably inserted into the guiding sleeve 17, with its upper end connected to the cross beam 16 and its lower end extending into the drying box body 1 and connected to the moving seat 10. During use, place the circular tray 8 loaded with powder into the tray card slot 7 in the tray rack 2. Control the telescopic end of the cylinder 15 to expand, thereby pushing the cross beam 16 downward. During the downward movement of the cross beam 16, the sliding rods 18 on both sides are pushed to move downward under the limiting action of the guiding sleeve 17, and the moving seat 10 is pushed to move downward along the guiding column 9. As a result, the raking component connected to the side wall of the moving seat 10 extends into the circular tray 8. During the rotation of the circular tray 8, the raking component rakes the powder, thereby improving the drying uniformity and operation efficiency. The raking component includes a connecting seat 19, an L-shaped rod 20 and a raking claw 21. The connecting seat 19 is assembled and connected to the side wall of the moving seat 10. The L-shaped rod 20 is welded to one end of the connecting seat 19 and extends above the tray. The raking claws 21 are uniformly welded to the lower end of the L-shaped rod 20 in the horizontal direction. Further, the raking claws 21 on the two L-shaped rods 20 at the same horizontal height are arranged staggeredly, which can effectively improve the uniformity of raking the powder. The powder is raked by the raking claws 21 at the lower part of the L-shaped rod 20. When the drying operation is completed, control the moving seat 10 to move upward so that the L-shaped rod 20 and the raking claws 21 move above the circular tray 8, facilitating the removal of the circular tray 8.
