[0035] The working principle of a vulcanization drying device provided by the present utility model is as follows: When performing vulcanization operation on the drying tank 1, first, the drug is transported to the material area 13 in the drying tank 1 through the feed port 7. Then, with the help of the compressor 3, a vacuum state is created inside the drying tank 1. After that, the air blower is used to blow air on the material, so that fine particles adhere to the filter bag 10 in the filter area 11 for drying and filtering. Then, a spraying operation is carried out through the spraying area 12, and at the same time, an adhesive is added to mix the material, causing the material to sink. Then, the exhaust gas in the drying tank 1 is guided and released through the induced draft fan 6 with the help of the exhaust valve 9. At this time, the mixing, drying, and granulation operations are completed.

[0036] During the vulcanization drying process of the drug, it is necessary to use the filter bag 10 in the internal filter area 11 of the drying tank 1 to adsorb and filter the particles. At this time, in order to facilitate the shedding of the fine particles on the surface of the filter bag 10, the servo motor 401 drives the eccentric block 402 and the slide plate 404 to perform reciprocating motion, so that the gear 407 on one side of the slide plate 404 rotates relative to the rack 406. At the same time, the gear 407 drives the relative shaking between the mounting frame 410 at the upper end of the entire filter bag 10 and the rotating shaft 408. During this process, with the help of the connecting groove 412 opened on the side wall of the mounting frame 410, the moving ring 413 in the connecting groove 412 drives the shaking between the entire top frame 411, the filter bag 10, and the bottom frame 417, so that the entire filter bag 10 vibrates, effectively and conveniently shaking off the drug particles on the surface of the filter bag 10.

[0037] When the filter bag 10 in the entire drying tank 1 is used for a long time, in order to facilitate the replacement and disassembly of the filter bag 10, at this time, with the help of the positioning frame 51 on the surface of the bottom frame 417 and the top frame 411, the position of the auxiliary frame 52 in the positioning frame 51 is rotated, and then the driving shaft 53 on the surface of the auxiliary frame 52 is rotated and adjusted, so that the two moving plates 56 on the surface of the driving shaft 53 squeeze and fix the filter bag 10, thereby performing replacement limit on the filter bag 10.
