[0021] Example

[0022] Please see Figure 1 , Figure 2 , Figure 3 ,and Figure 4 This utility model provides a technical solution: a filtration device for pharmaceutical production, including a processing cylinder 1, a rotating assembly 2 movably connected inside the processing cylinder 1, a positioning plate 5 fixedly connected to one side surface of the upper half of the processing cylinder 1, a rotating rod 6 movably connected to the outer side of the positioning plate 5, six rotating rods 6 arranged in a circumferential array evenly distributed, a rotating disk 7 movably connected to the upper end of the rotating rod 6, and a linkage ring 10 movably connected to the lower end of the rotating rod 6. The processing cylinder 1 is divided into two parts, the upper half and the lower half are connected to each other, and the lower half of the processing cylinder 1 can also be used as a carrier after filtration.

[0023] The two ends of the rotating rod 6 are fixedly connected with snap-fit ​​balls 9. The rotating disk 7 and the linkage ring 10 are both provided with spherical holes 8 on one side surface. There are six spherical holes 8 on one side surface of the rotating disk 7 and the linkage ring 10. The six spherical holes 8 are evenly distributed in a circumferential array. The positions of the two sets of linkage rings 10 and the rotating disk 7 are corresponding to each other. The six rotating rods 6 use the snap-fit ​​balls 9 at both ends to splice the rotating disk 7 and the linkage ring 10 into a synchronously moving structure.

[0024] A conical frame 11 is provided at the lower end of the linkage ring 10, and a snap ring 12 is fixedly connected to the upper end of the conical frame 11. A filter screen 13 is provided between the linkage ring 10 and the snap ring 12. The conical frame 11 is snapped at the lower end of the linkage ring 10 by the snap ring 12. The upper end of the conical frame 11 is used to facilitate the placement of the filter screen 13. The conical frame 11 uses the snap ring 12 to snap at the lower end of the linkage ring 10 while securing the position of the filter screen 13.

[0025] A spring 14 is provided on the outside of the rotating rod 6. One end of the spring 14 is fixed to one end of the rotating rod 6, and the other end of the spring 14 is fixedly connected to one side surface of the positioning plate 5. The spring 14 is used to stabilize the back-and-forth movement of the rotating rod 6 on one side of the positioning plate 5 and prevent misalignment and displacement.

[0026] A linkage rod 15 is fixedly connected to the upper end of the rotating disk 7, and an adjusting block 16 is fixedly connected to the upper end of the linkage rod 15. A snap-fit ​​groove 17 is provided at the upper end of the processing cylinder 1. The adjusting block 16 and the snap-fit ​​groove 17 are mutually adapted to each other. The adjusting block 16 snaps and moves inside the snap-fit ​​groove 17. At the same time, moving one end of the adjusting block 16 can drive the rotating disk 7 and the related lower part of the whole to rotate and the filter screen 13 to be used.

[0027] The lower end of the conical frame 11 is movably connected to a guide rod 18. A central slot 19 is opened on one side of the inner surface of the lower half of the treatment cylinder 1. One end of the guide rod 18 is movably connected to the inside of the central slot 19. The filtered agent is guided to the inside of the lower half of the treatment cylinder 1 through the guide rod 18.

[0028] The outer side of the processing cylinder 1 is fixedly connected to the feed hopper 3, and the inner side of the processing cylinder 1 is fixedly connected to the discharge pipe 4. The inner side of the feed hopper 3 and the inner side of the discharge pipe 4 are interconnected. One end of the discharge pipe 4 is directly opposite the center position of the positioning plate 5 and the other end is directly opposite the center position of the filter screen 13. The medicine to be filtered is poured in through the inlet of the feed hopper 3. The medicine flows through the discharge pipe 4 and flows out from one end of the discharge pipe 4 into the interior of the filter screen 13.

[0029] Before using the filtration device, the entire unit is sterile cleaned. After cleaning, the corresponding filter screen 13 is placed on the upper end of the conical frame 11 as needed. At the same time, the position of the filter screen 13 is secured by the snap ring 12, which is fastened to the lower end of the linkage ring 10. This ensures that the filter screen 13 is stably placed during use and makes it quicker and more convenient to replace. Then, the required filtration agent is poured in through the inlet of the feed hopper 3. The agent flows through the discharge pipe 4 and flows out from one end of the discharge pipe 4 into the interior of the filter screen 13. Then, the adjusting block 16 is rotated, which drives the rotating disk 7 and the relevant components at the lower end to rotate in linkage. When the filter screen 13 rotates in a circle, it can make full use of all parts of the filter screen 13 for filtration, thereby effectively increasing the filtration area. A larger filtration area means that it can hold more impurities, extend the service life of the filter, and reduce the frequency of replacing the filter screen 13. The filtered agent flows into the lower half of the processing cylinder 1. After filtration, the entire unit is removed for the next operation. At the same time, the entire unit is sterile cleaned again for the next use.
