Existing equipment usually adopts a simple centrifugal drying method, which cannot apply continuous pressure to the raw materials, resulting in poor dehydration effect and lack of effective drug recovery structure, causing raw material waste. At the same time, in the dehydration process, pharmaceutical raw materials are prone to sticking to the outer wall of the filter cartridge, affecting the dehydration efficiency.

[0003] Therefore, there is an urgent need for a centrifugal dehydration device that can improve dehydration efficiency, reduce drug loss, and is easy to operate. Utility Model Content

[0006] Furthermore, a guide ring is provided between the lower end of the filter cylinder and the outer cylinder, and the guide ring discharges the splashed water downwards.

[0007] Furthermore: a filter ring is fixed to the lower end of the outer cylinder and the lower end of the guide ring, and a water-collecting ring is fixed to the outside of the filter ring.

[0008] Furthermore: a scraper is fixed to the inner wall of the outer cylinder, and the end of the scraper is abutted against the outer wall of the filter cylinder.

[0009] Furthermore, the guide rod can be adjusted by rotating the thread to change the downward pressure position of the pressure plate inside the filter cylinder.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6This utility model provides a technical solution: a centrifugal dehydration and drying device for pharmaceutical raw materials; specifically, it includes a base 1 and an outer cylinder 5, with a filter cylinder 4 rotatably arranged inside the outer cylinder 5. A support frame 2 is fixed at the lower end of the base 1, and a motor 3 is fixedly connected inside the support frame 2. The output end of the motor 3 is matched and corresponding to the lower end of the filter cylinder 4. The motor 3 drives the filter cylinder 4 to rotate, and the pharmaceutical raw materials are placed inside the filter cylinder 4. Then, the cover 6 set at the upper end of the outer cylinder 5 is closed. The motor 3 drives the filter cylinder 4 to rotate at high speed, and the pharmaceutical raw materials are removed. The filter cylinder 4 is rotated at high speed to remove water, which is a known technology and will not be described in detail here. A limiting groove 10 is provided on the inner side wall of the filter cylinder 4. A pressure plate 8 is provided inside the filter cylinder 4. A slider 9 is fixedly connected to the side wall of the pressure plate 8. The slider 9 is located in the limiting groove 10 and slides up and down. The pressure plate 8 rotates with the rotation of the filter cylinder 4. A guide rod 7 is threadedly connected to the cover 6. The threaded rotation of the guide rod 7 presses the pressure plate 8 down. It can rotate downward after rotating for a period of time, so that the water removed is drier.

[0022] A guide ring 12 is provided between the lower end of the filter cylinder 4 and the outer cylinder 5. The guide ring 12 discharges the water that has been spun out to the lower side. A filter ring 13 is fixed at the lower end of the outer cylinder 5 and the lower end of the guide ring 12. The filter ring 13 can prevent the raw material particles of the medicine from flowing out of the filter ring 13, thereby reducing the loss of medicine. A water receiving ring 14 is fixed on the outside of the filter ring 13. The water is collected and discharged through the water receiving ring 14, which enables centralized management and improves the efficiency of spun drying.
