Specific embodiments
[0023] As Figures 1 to 5 shown, a uniform air-flow drying device for refined cotton processing includes a hot blast stove 1 for providing high-temperature air flow. The hot blast stove 1 is connected to a drying cylinder 2 through a feed pipe 17. An upward-opening feed port is connected to the outside of the feed pipe 17. The numbers of the drying cylinders 2 and the feed pipes 17 are both set to be multiple. The two drying cylinders 2 are connected through the feed pipe 17. One end of the feed pipe 17 is connected to a cyclone 18. The refined cotton raw material enters the drying cylinder 2 through the feed port by the feed pipe 17, and is drawn into the cyclone 18 together with the hot air around the pipeline by a fan. The dried refined cotton raw material is then released from the cyclone 18, and the waste hot air and water vapor are discharged from above the cyclone 18. A hollow cylinder 3 is fixedly connected to the middle of the drying cylinder 2. A barrier member 4 is hermetically slid inside the hollow cylinder 3. Heat dissipation holes 5 are opened on the barrier member 4. An elastic component for resetting the barrier member 4 is arranged on the top of the barrier member 4; the elastic component includes a first telescopic rod 6 and a spring 7. The spring 7 is arranged outside the first telescopic rod 6. A support frame 8 is fixedly connected to the inner wall of the drying cylinder 2. The support frame 8 and the barrier member 4 are fixed through a second telescopic rod 9, and the elastic component is fixedly connected to the support frame 8.
[0024] During specific operation, the high-temperature air flow blown out by the hot blast stove 1 pushes the moist refined cotton raw material into the cavity of the drying cylinder 2 from the bottom of the drying cylinder 2. A barrier member 4 is arranged inside the hollow cylinder 3. The moist refined cotton raw material is first pushed onto the surface of the barrier member 4. As the refined cotton accumulates, the surface of the heat dissipation holes 5 on the barrier member 4 is blocked. At this time, the air pressure inside the drying cylinder 2 near the hot blast stove 1 increases. Therefore, the high-temperature air flow can push the barrier member 4 to move upward along the drying cylinder 2 against the action force of the elastic component. Since the inner diameter of the hollow cylinder 3 is smaller than the inner diameter of the drying cylinder 2, and the barrier member 4 is limited by the second telescopic rod 9, the barrier member 4 moves from the cavity of the hollow cylinder 3 to the inner cavity of the drying cylinder 2. At this time, a gap is generated between the barrier member 4 and the inner wall of the drying cylinder 2. One side of the barrier member 4 close to the feed port of the drying cylinder 2 is set as an arc surface. The barrier member 4 with an arc surface makes the blocked refined cotton more convenient to be discharged from the gap under the blowing force of the high-temperature air flow. Since the elastic force of the elastic component is greater than the thrust of the high-temperature air flow blown out by the hot blast stove 1, the barrier member 4 is reset under the action force of the elastic component and continues to intercept the refined cotton. By means of the barrier member 4, the time of the refined cotton in the drying cylinder 2 can be effectively extended, the drying degree of the refined cotton is improved, and the drying effect is ensured.
[0025] As Figures 4 to 6 shown, a partition plate 10 is rotatably connected inside the barrier member 4 in a sealed manner. One side of the partition plate 10 close to the elastic component is fixedly connected with a connecting rod 11. One end of the connecting rod 11 contacts the elastic component. A sleeve 12 is sleeved outside the elastic component. The sleeve 12 is fixedly connected to the support frame 8. A threaded groove 13 is formed inside the sleeve 12. A sliding block 14 is fixedly connected to the outside of the connecting rod 11. One end of the sliding block 14 is arranged in the threaded groove 13 and is slidably matched with it. A loosening component is arranged on one side of the barrier member 4 away from the elastic component.
[0026] The loosening component includes a first dispersing member 15. The first dispersing member 15 is fixedly connected to one side of the barrier member 4. A second dispersing member 16 is arranged inside the first dispersing member 15. The second dispersing member 16 is fixedly connected to one side of the partition plate 10.
[0027] A plurality of first comb teeth are annularly distributed on both the first dispersing member 15 and the second dispersing member 16, and the plurality of first comb teeth on the first dispersing member 15 and the second dispersing member 16 are staggeredly distributed.
[0028] The cross-sectional shape of the second dispersing member 16 away from the central part of the partition plate 10 is triangular, which is convenient for the intercepted delicate cotton to be located between the comb teeth of the first dispersing member 15 and the second dispersing member 16.
[0029] During specific operation, as the surface of the heat dissipation hole 5 is blocked by refined cotton, while the barrier member 4 moves towards the discharge port of the drying cylinder 2 against the acting force of the elastic component, the partition plate 10 moves along with the barrier member 4. When the partition plate 10 moves, it drives the connecting rod 11 to move against the acting force of the elastic component. The movement of the connecting rod 11 enables the slider 14 to slide within the threaded groove 13. The sliding of the slider 14 within the threaded groove 13 can drive the connecting rod 11 to rotate. The rotation of the connecting rod 11 drives the partition plate 10 to rotate. During this process, the barrier member 4 always moves in a straight line under the limit of the second telescopic rod 9. That is to say, during this process, the first dispersing member 15 in the loosening component rotates, while the second dispersing member 16 remains stationary. Through the staggered distribution of a plurality of first comb teeth on the first dispersing member 15 and the second dispersing member 16, the refined cotton is dispersed horizontally. Then, through the installation of a plurality of second comb teeth arranged in parallel in the vertical direction on each first comb tooth, the refined cotton is dispersed vertically upwards. The refined cotton is dispersed in multiple directions through the first brush teeth and the second comb teeth arranged on the first dispersing member 15 and the second dispersing member 16. Combined with the high-temperature airflow blown out by the hot blast stove 1, the drying degree of the refined cotton can be further improved, and the drying effect can be enhanced.
