[0002] Ammonium sulfate is an inorganic salt, mainly used as a fertilizer, suitable for various soils and crops. It can also be used in textiles, leather, medicine and other aspects. Ammonium sulfate is suitable as a nitrogen fertilizer variety because it has the advantages of fast fertilizer efficiency and high stability. It is also one of the main raw materials for compound fertilizers by the granulation method, suitable for general soils and crops, which can make the branches and leaves grow vigorously, improve the fruit quality and yield, and increase the ability of crops to resist disasters. Ammonium sulfate can be used as a basal fertilizer, top dressing and seed fertilizer. During the raw material production and processing process, it needs to be cooled by a cooling drum.

[0003] After retrieval, the Chinese patent publication number: CN220658251U discloses a discharge assembly for a fertilizer cooling drum. By using a screening assembly on the cooling drum, the cooled fertilizer particles can be screened out during the discharge process of the cooling drum, improving the production quality.

[0035] Referring to Figures 1-3 , a thread groove 5 is opened on the surface of the connecting cylinder 2, a positioning hole 7 is opened on the surface of the second screening cylinder 4, several groups of positioning holes 7 are opened, and several groups of positioning holes 7 are arranged in a circumferential array with the center point of the second screening cylinder 4 as the axis of symmetry. An avoidance groove 8 is opened on the outer wall of the connecting cylinder 2, and three groups of avoidance grooves 8 are opened, which are arranged at equal distances with the center point of the connecting cylinder 2 as the center. The inner wall of the avoidance groove 8 is threadedly connected with a threaded rod 9, and the number of threaded rods 9 arranged is the same as that of the avoidance grooves 8. The triangular positioning between the connecting cylinder 2 and the threaded cylinder 6 is realized by connecting the three threaded rods 9 with the positioning holes 7, increasing the stability of their connection. An annular groove 10 is opened on the surface of the connecting cylinder 2, and a moving block 11 is slidably connected to the inner wall of the annular groove 10. There are two groups of moving blocks 11, and they are arranged in a mirror image with the axis of symmetry of the collar 12. The outer wall of the moving block 11 is fixedly connected with a collar 12, and the bottom of the collar 12 is fixedly connected to the bottom plate through a support column. An insertion hole 13 is opened through the surface of the collar 12, a positioning plate 14 is fixedly connected to the side wall of the collar 12, a bolt 15 is threadedly connected to the inner wall of the positioning plate 14, an insertion post 16 is arranged on the outer wall of the insertion hole 13, a mounting plate 17 is slidably connected to the surface of the insertion post 16, and a cleaning brush 18 is fixedly connected to the top of the mounting plate 17. The cleaning brush 18 cleans the outer wall of the second screening cylinder 4, and the bristles can be embedded into the screening holes of the second screening cylinder 4 to prevent blockage between the first screening cylinder 3 and the second screening cylinder 4.

[0036] Referring to Figures 3-4, the outer wall of the threaded cylinder 6 is threadedly connected to the inner wall of the threaded groove 5. After the threaded cylinder 6 is completely embedded in the threaded groove 5, the second sieve cylinder 4 will be in contact with the connecting cylinder 2. One end of the threaded cylinder 6 away from the threaded groove 5 is fixedly connected to the outer wall of the first sieve cylinder 3. The outer wall of the second sieve cylinder 4 is rotatably connected to the outer wall of the threaded cylinder 6. Rotating the second sieve cylinder 4 can adjust the alignment degree of the sieve holes between the second sieve cylinder 4 and the first sieve cylinder 3, facilitating the adjustment of the particle size of the screening. The inner wall of the positioning hole 7 is threadedly connected to the outer wall of the threaded rod 9. The inner wall of the insertion hole 13 is adapted to the inner wall of the insertion post 16. The inner wall of the insertion post 16 is threadedly connected to the outer wall of the bolt 15. One end of the cleaning brush 18 away from the mounting plate 17 is in contact with the outer wall of the second sieve cylinder 4.

[0037] Referring to Figures 4-5 , a promoting structure is provided on the surface of the mounting plate 17. The promoting structure includes a slider 19. A fixing plate 22 is provided at the bottom of the mounting plate 17. The mounting plate 17 can slide horizontally on the surface of the insertion post 16 for a certain distance. A chute 20 is opened on the upper surface of the fixing plate 22. A spring 21 is fixedly connected to the inner wall of the chute 20.

The top of the slider 19 is fixedly connected to the outer wall of the mounting plate 17 on the side away from the cleaning brush 18. The bottom of the slider 19 is slidably connected to the inner wall of the chute 20. One end of the spring 21 away from the chute 20 is fixedly connected to the outer wall of the slider 19. The outer wall of the fixing plate 22 is fixedly connected to the outer wall of the insertion post 16 on the side close to the mounting plate 17. When the second sieve cylinder 4 rotates integrally with the cooling drum body 1, the cleaning brush 18 will clean and discharge the blocked particles inside it. The cleaning brush 18 will drive the slider 19 to slide in the chute 20 under force, and the spring 21 helps the slider 19 to reset.

[0038] Working principle: the sieve drum 1 3 and the sieve drum 2 4 screen the particles after cooling so that smaller particles can be discharged directly. When the spacing between the sieve holes of the sieve drum 1 3 and the sieve drum 2 4 needs to be adjusted, the operator manually reverses the threaded rod 9 to make the threaded rod 9 gradually disengage from the corresponding positioning hole 7 and move toward the inner wall of the connecting cylinder 2. When the three groups of threaded rods 9 are all disengaged from the corresponding positioning holes 7, the sieve drum 2 4 is manually rotated to rotate on the threaded cylinder 6. After judging the distance between the sieve holes, the threaded rod 9 is rotated forward in sequence to gradually insert it into the positioning hole 7 to position the sieve drum 2 4. At the same time, when the sieve drum 1 3 and the sieve drum 2 4 screen the particles, the cleaning brush 18 cleans the inside of the sieve hole to reduce the risk of blockage. At the same time, during the rotation of the sieve drum 2 4, a certain force is applied to the cleaning brush 18, so that the mounting plate 17 drives The slider 19 slides in the slide groove 20 for a distance, and the spring 21 is deformed, so that the cleaning brush 18 can move back and forth to prevent the cleaned particles from being embedded in the bristles of the cleaning brush 18. The cleaned particles fall downward through the through hole 23 and are stored in the collection box placed outside. When the screen cylinder 1 3 and the screen cylinder 2 4 need to be cleaned after long-term use, first repeat the above steps on the threaded rod 9 to separate it from the positioning hole 7, manually hold the screen cylinder 1 3 and the screen cylinder 2 4 and reverse them at the same time, the threaded cylinder 6 will gradually separate from the threaded groove 5, and the screen cylinder 1 3 and the screen cylinder 2 4 can be removed for cleaning. At the same time, reverse the bolt 15 until it gradually disengages from the plug post 16, and then apply force to the fixing plate 22 to pull it outward, the plug post 16 will disengage from the inside of the socket 13, which is convenient for cleaning the cleaning brush 18, thereby improving the cleanliness after cooling during production.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
