Four second rotating shafts 19 are arranged laterally outside the two limiting rods 16 under the fixed plate 14, and the second rotating shafts 19 are rotatably mounted on the lower surface of the fixed plate 14. The four second rotating shafts 19 arranged laterally on both sides of the two limiting rods 16 and the two first rotating shafts 18 at both ends of the four sliding plates 17 are respectively located on both sides of the ends of the three sets of screening components and on the outside of the two adjacent side plates 10. Threaded holes are provided through the sides of the four sliding plates 17. A threaded rod 20 is simultaneously installed inside the lower housing 3. The feed inlet 5 is installed at the higher end of the lower housing 3, and the discharge outlet 6 is installed at the lower end of the lower housing 3. Both rotating shafts 7 are parallel to each other at the bottom of the lower housing 3 and are parallel to each other. The diameter of the screen holes of the three filter cylinders 9 increases sequentially from the feed inlet 5 to the discharge outlet 6. The center lines of the side plate 10 and the toothed ring 11 coincide with the center line of the filter cylinder 9. The fixing strip 12 is parallel to the center line of the filter cylinder 9. The rotating shafts 7 are parallel to the center line of the filter cylinder 9. The limiting plate 15 is perpendicular to the fixing plate 14. The screening assembly is located directly below the limiting adjustment assembly. Both limiting rods 16 are parallel to the fixing plate 14.The central axis of the first rotating shaft 18 is parallel to the central axis of the second rotating shaft 19. Both the first rotating shaft 18 and the second rotating shaft 19 are perpendicular to the fixed plate 14. The threaded rods 20 in the limit adjustment components inside the lower housing 3 and the upper housing 4 are respectively mounted with rotating disks 21 through the lower housing 3 and the upper housing 4. Motors 13 are respectively mounted on the ends of the two rotating shafts 7. The two motors 13 are respectively mounted on the outer wall of the lower housing 3 by fixing components. Feed pipes 22 and discharge pipes 23 are respectively provided on the outer side of the three sets of screening components. The feed pipe 22 is rotatably installed inside the feed inlet 5, and the discharge pipe 23 is rotatably installed inside the discharge outlet 6. Side plates 10 are respectively installed at the other ends of the feed pipe 22 and the discharge pipe 23. Toothed rings 11 are respectively installed on the other sides of the side plates 10 installed on the feed pipe 22 and the discharge pipe 23. Three slag discharge ports 25 are arranged horizontally at the bottom of the lower housing 3, and the three slag discharge ports 25 are respectively located directly below the filter cylinders 9 of the three screening components. Partition plates 24 are respectively installed on both sides of the openings of the three slag discharge ports 25 at the bottom of the lower housing 3.

[0026] During operation, existing rotary screens suffer from low screening efficiency and poor screening effect, and the replacement of the drums is inconvenient and slow, affecting production efficiency. In this solution, two motors 13 are controlled to drive in the same direction. When the two motors 13 are running, they will drive two rotating shafts 7 to rotate in the lower housing 3. The toothed rings 11 at the ends of the two adjacent filter cylinders 9 mesh with the same gear 8, which is mounted between the two rotating shafts 7. When the rotating shafts 7 rotate, they will drive the adjacent toothed rings 11 to rotate through the gear 8, which in turn drives the filter cylinders 9 to rotate. The slag is fed in from the feed inlet 5 and enters the three filter cylinders 9 from the feed pipe 22. After entering the three filter cylinders 9, the slag gradually... The filter cylinder 9 rolls out towards the discharge pipe 23. As it rotates, the filter cylinder 9 agitates the slag inside via the fixing bar 12, screening the slag. The screened slag falls from the bottom of the lower housing 3 and is discharged from the slag outlet 25 at the bottom of the lower housing 3. Larger minerals enter the discharge pipe 23 and are finally discharged from the discharge outlet 6. The rotation of the filter cylinder 9 drives the first rotating shaft 18 and the second rotating shaft 19 to rotate under the fixing plate 14 via the side plates 10 at both ends. When the filter cylinder 9 needs to be replaced, the rotating disc 21 is rotated. The rotation of the rotating disc 21 drives the threaded rod 20 to rotate, which in turn drives the sliding plate 17 to slide on the limit rod 16. As the sliding plate 17 moves... This will cause the first rotating shaft 18 to move, and when the sliding plate 17 moves, it will cause the first rotating shaft 18 to move away from its corresponding second rotating shaft 19, thereby causing the side plates 10 at both ends of the adjacent filter cylinder 9 to be unrestricted. Then, the upper housing 4 will be flipped open from above the lower housing 3, and the filter cylinder 9 to be replaced can be taken out from the lower housing 3. At this time, the toothed ring 11 at the end of the removed filter cylinder 9 will separate from the adjacent toothed ring 11. Then, the required filter cylinder 9 will be placed in the notch position, so that the side plates 10 and toothed ring 11 at both ends of the inserted filter cylinder 9 are respectively located between the partition plates 24 on both sides of the opening of the slag discharge port 25, and the teeth of the toothed ring 11 at both ends of the inserted filter cylinder 9 correspond to the teeth of the toothed ring 11 at the end of the adjacent filter cylinder 9, so that the teeth of the inserted filter cylinder 9 at both ends... The toothed ring 11 and the toothed ring 11 at the end of the adjacent filter cylinder 9 simultaneously mesh with the gear 8. Then, the upper housing 4 is flipped over and placed on the lower housing 3. At this time, the first rotating shaft 18 and the second rotating shaft 19 set under the fixed plate 14 will be located on the outside of the side plates 10 at both ends of the three filter cylinders 9 respectively. Then, the rotating disk 21 is rotated again, so that when the threaded rod 20 rotates, it drives the second rotating shaft 19 to move closer to its corresponding first rotating shaft 18 through the sliding plate 17. Under the close clamping of the first rotating shaft 18 and the second rotating shaft 19, the side plates 10 at both ends of the adjacent filter cylinders 9 will be squeezed, thereby connecting the ends of the adjacent filter cylinders 9 and achieving the screening function. Compared with the traditional drum screen, it is more convenient and faster to replace the drum, and the screening efficiency is higher.

[0027] Working principle: By controlling two motors 13 to drive in the same direction, the two motors 13 will drive two rotating shafts 7 to rotate inside the lower housing 3. The toothed rings 11 at the ends of the two adjacent filter cylinders 9 mesh with the same gear 8, which is mounted between the two rotating shafts 7. When the rotating shafts 7 rotate, they will drive the adjacent toothed rings 11 to rotate through the gear 8, which in turn drives the filter cylinders 9 to rotate. The slag is fed in from the feed inlet 5 and enters the three filter cylinders 9 from the feed pipe 22. After entering the three filter cylinders 9, the slag will gradually roll out towards the discharge pipe 23. When the filter cylinders 9 rotate, the fixed strips 12 will agitate the slag inside. During the turning process, the filter cylinder 9 can screen the slag inside. The screened slag falls from the bottom of the lower shell 3 and is discharged from the slag discharge port 25 at the bottom of the lower shell 3. Larger minerals enter the discharge pipe 23 and are finally discharged from the discharge port 6. When the filter cylinder 9 rotates, it drives the first rotating shaft 18 and the second rotating shaft 19 to rotate under the fixed plate 14 through the side plates 10 at both ends. When the filter cylinder 9 needs to be replaced, the rotating disk 21 is rotated. When the rotating disk 21 rotates, it drives the threaded rod 20 to rotate. When the threaded rod 20 rotates, it drives the sliding plate 17 to slide on the limit rod 16. When the sliding plate 17 moves, it drives the first rotating shaft 18 to move. The control makes the sliding plate 17 move and drive the first rotating shaft 18 to move. The first rotating shaft 18 moves away from its corresponding second rotating shaft 19, thereby freeing the side plates 10 at both ends of the adjacent filter cylinder 9 from restriction. Then, the upper housing 4 is flipped open from above the lower housing 3, allowing the filter cylinder 9 to be replaced to be removed from the lower housing 3. At this point, the toothed ring 11 at the end of the removed filter cylinder 9 will separate from the adjacent toothed ring 11. The required filter cylinder 9 is then placed in the notch position, with the side plates 10 and toothed ring 11 at both ends of the inserted filter cylinder 9 positioned between the partitions 24 on both sides of the slag discharge port 25 opening, and the teeth of the toothed ring 11 at both ends of the inserted filter cylinder 9 corresponding to the teeth of the toothed ring 11 at the end of the adjacent filter cylinder 9. The gear ring 11 of the part meshes with the gear 8 at the same time. Then the upper housing 4 is flipped over and covered on the lower housing 3. At this time, the first rotating shaft 18 and the second rotating shaft 19 set under the fixed plate 14 will be located on the outside of the side plates 10 at both ends of the three filter cylinders 9 respectively. Then the rotating disk 21 is rotated again, so that when the threaded rod 20 rotates, it drives the second rotating shaft 19 to move closer to its corresponding first rotating shaft 18 through the sliding plate 17. Under the close clamping of the first rotating shaft 18 and the second rotating shaft 19, the side plates 10 at both ends of the adjacent filter cylinders 9 will be squeezed, thereby connecting the ends of the adjacent filter cylinders 9 and achieving the screening function. Compared with the traditional drum screen, it is more convenient and faster to replace the drum, and the screening efficiency is higher.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
