[0002] Molecular sieve catalysts need to be ground during the preparation process. Grinding can refine the particles of molecular sieve catalysts, making them more uniform in size. At the same time, sieving after grinding can classify the catalyst particles according to different particle size ranges.
[0003] Conventional screening equipment uses a sieve screen inside the equipment for grading and screening. However, the traditional sieve screen is fixed in a fixed position inside the equipment, which means that the molecular sieve cannot make sufficient contact with the surface of the sieve screen after grinding. This results in a lower screening effect of the molecular sieve and a reduction in the overall screening efficiency.
[0004] Therefore, we propose a molecular sieve catalyst grinding, classification and screening device to solve the above problems. Utility Model Content

A rolling groove is formed inside one side of the annular plate, and a roller is rolled and embedded inside the rolling groove. The roller has a slot in its wall, and one end of the screening screen is inserted into the slot. A placement plate is fixed inside the other side of the annular plate, and a baffle is provided at the upper end of the placement plate. A rotating groove is formed on the inner side wall of the annular plate to cooperate with the rotation of the baffle. A vertical rod is fixed on the inner wall of the rotating groove. The baffle is rotatably sleeved on the outside of the vertical rod. A torsion spring is sleeved on the wall of the vertical rod, and the two ends of the torsion spring are fixedly connected to the vertical rod and the baffle, respectively.

Detailed Implementation To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This utility model discloses a molecular sieve catalyst grinding, grading and screening device.
[0023] This utility model provides a molecular sieve catalyst grinding, grading and screening device as shown in Figures 1-4, including a screening box 1 and a grinding feed pipe 2 fixedly installed on the upper side of the screening box 1. A vibration motor 6 is fixedly installed at the bottom of the screening box 1. A box door is provided on the front side of the screening box 1. Multiple rotating rods 3 are rotatably arranged at intervals on both sides of the screening box 1. An annular plate 4 is fixedly installed between two adjacent rotating rods 3. An elastic air bag 22 is fixedly installed on both sides of the annular plate 4. The outer side of the elastic air bag 22 contacts and cooperates with the inner side wall of the screening box 1. A screening mesh 5 is embedded inside each annular plate 4. A reciprocating rotation mechanism is provided at the rear end of the multiple rotating rods 3.
[0024] Before sieving the molecular sieve, the molecular sieve is ground by a grinding device, and after grinding, the raw material is fed into the screening box 1 through the grinding feed pipe 2. At this time, the molecular sieve raw material comes into contact with the screening mesh 5 inside the top annular plate 4, and the molecular sieve is initially screened. As the screening work proceeds, multiple rotating rods 3 drive the screening mesh 5 to swing back and forth, so that the molecular sieve can make full contact with the surface of the screening mesh 5 over a large area, which can improve the screening of the molecular sieve. At the same time, with the longitudinal cooperation of multiple screening meshes 5, the molecular sieve can be graded and screened, which improves the screening effect and the preparation effect of the molecular sieve.
[0025] In order to enable multiple sieve screens 5 to reciprocate and oscillate effectively for screening of molecular sieves, such as Figure 1-2As shown, the reciprocating rotation mechanism includes a vertical plate 7, and transmission gears 8 are fixedly sleeved on the rear ends of multiple rotating rods 3. Each transmission gear 8 is meshed with a drive rack 9. Multiple drive racks 9 are fixedly connected to the vertical plate 7. A drive motor 10 is fixedly installed on the outer wall of the screening box 1. A slide rod 11 is fixedly installed on the outer wall of the vertical plate 7. A slide tube 12 is slidably sleeved on the outer side of the slide rod 11. The longitudinal sections of the slide rod 11 and the slide tube 12 are both square. The slide tube 12 is fixedly connected to the screening box 1. A rotating plate 13 is fixedly installed at the end of the output shaft of the drive motor 10. A connecting rod 14 is fixedly installed on the outer wall of both the rotating plate 13 and the slide tube 12. A connecting plate 15 is rotatably sleeved on the outer side of the two connecting rods 14.
[0026] Before the screening operation begins, the drive motor 10 is turned on. At this time, the drive motor 10 drives the rotating plate 13 to rotate. Under the rotational connection of the connecting rod 14 and the connecting plate 15, the slide rod 11 slides back and forth in the slide tube 12. Through the connection of the vertical plate 7, multiple drive racks 9 move laterally back and forth. At this time, under the meshing action of the drive racks 9 and the transmission gear 8, the transmission gear 8 drives the rotating rod 3 to rotate back and forth, causing the annular plate 4 and the screening screen 5 to swing back and forth, thus effectively oscillating and screening the molecular sieve.
[0027] To facilitate the easy disassembly and replacement of the screening screen 5, as shown in Figures 3-4, a rolling groove is provided inside one side of the annular plate 4. A roller 16 is rolled and embedded inside the rolling groove. A slot 17 is provided on the wall of the roller 16. One end of the screening screen 5 is inserted into the slot 17. A placement plate 18 is fixedly provided inside the other side of the annular plate 4. A baffle 19 is provided at the upper end of the placement plate 18. A rotating groove is provided on the inner side wall of the annular plate 4 to cooperate with the rotation of the baffle 19. A vertical rod 20 is fixedly provided on the inner wall of the rotating groove. The baffle 19 is rotatably sleeved on the outside of the vertical rod 20. A torsion spring 21 is sleeved on the wall of the vertical rod 20. The two ends of the torsion spring 21 are fixedly connected to the vertical rod 20 and the baffle 19, respectively.
[0028] When using the screening screen 5, one end of the screening screen 5 is inserted into the slot 17, while the other end is set in the baffle 19 and the placement plate 18. When the screening screen 5 needs to be disassembled and replaced, the baffle 19 can be rotated so that the baffle 19 rotates around the vertical rod 20. At this time, one end of the screening screen 5 can be pulled to make the screening screen 5 tilt. At this time, the other end of the screening screen 5 rotates synchronously under the rotation cooperation of the roller 16 and the rolling groove. Then, the lower end of the screening screen 5 can be directly pulled out from the slot 17.
[0029] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
