A separation component 9 is provided inside the left side space of the recycling bottom shell 2. The separation component 9 includes a separation partition 91 fixedly connected to the left side space inside the recycling bottom shell 2.

The follower screen plate 92 includes a connecting rod 921 fixedly connected to the front of the connecting slide tube 625. A follower plate assembly 922 is fixedly connected to the bottom of the connecting rod 921.

The follower plate assembly 922 is located in the closed space formed by the adjacent separation partition 91. The right side of the front of the circulation housing 1 is connected to a secondary separation pipe 10. The end of the secondary separation pipe 10 is inclined downward.

The right side of the inside of the recovery bottom housing 2 is a low temperature air intake zone 11. The right side of the bottom of the circulation housing 1 is connected to an air intake plate 12.

[0021] During use, the gas carrying impurities from the production of antibacterial dressings enters the interior of the circulation housing 1 through the air inlet 3. The gas passes through the follow-up inner frame 62, and impurities of different diameters carried in the gas are intercepted by the corresponding inclined filter plate group 623. The impurities fall along the space inside the corresponding separation constraint frame 8, enter the left side of the interior of the recycling bottom shell 2, and finally fall into the corresponding recycling container. The gas leaving the circulation housing 1 re-enters the circulation housing 1 through the transfer pipe 4. At this time, the gas enters the right side area inside the circulation housing 1, and finally leaves from the exhaust port 5. When the gas passes through the drive assembly 7, the airflow drives the sliding impeller tube 71 to rotate, the sliding impeller tube 71 drives the eccentric block 72 to rotate, the eccentric block 72 drives the follower slide rod 621 to slide back and forth, the follower slide rod 621 drives the mounting plate 622 to drive the inclined filter plate assembly 623 to slide back and forth, so that the inclined filter plate assembly 623 vibrates periodically to prevent the inclined filter plate assembly 623 from clogging. At the same time, the follower screen plate 92 also slides back and forth under the drive of the follower slide rod 621 to prevent clogging in the left side area of ​​the inner wall of the recovery bottom shell 2. The motor periodically drives the active outer frame 61 to rotate 180 degrees, thereby periodically replacing the inclined filter plate group 623 for impurity recovery. During the rotation, the impurities attached to the inner wall of the separation constraint frame 8 are loosened under the influence of centrifugal force. Impurities of different volumes and sizes slide horizontally and then vertically in the corresponding vertical arrangement area. When the impurities slide vertically from the vertical arrangement area, they are subjected to the combined action of centrifugal force and their own gravity, and are finally thrown to the outside of the secondary separation tube 10 when the separation constraint frame 8 is connected to the secondary separation tube 10. The air pump discharges the low-temperature air from the outside into the low-temperature air intake zone 11 inside the recovery bottom shell 2. The low-temperature gas enters the air intake plate 12 from the low-temperature air intake zone 11, thereby reducing the temperature on the right side of the inner wall of the circulation shell 1 separated by the partition scraper 63.
