Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve preparation, in particular to a system for processing materials after pelletization. Background Art

[0002] Molecular sieves are synthetic hydrated aluminosilicates (zeolites) or natural zeolites that have the ability to screen molecules. Their structure consists of many channels with uniform pore sizes and neatly arranged pores. Molecular sieves of different pore sizes separate molecules of different sizes and shapes.

[0003] Most molecular sieves are spherical, and their sizes are mostly in the millimeter or micron order, so they can also be called molecular sieve microspheres. Molecular sieves are mostly prepared using a pelletizer. The main principle is to put powdered raw materials into the pelletizer, and then spray water or binder into the pelletizer. Under the action of continuous rotation, the powder gradually sticks into balls. However, the final product contains not only molecular sieves that meet the requirements, but also molecular sieves that are oversized, molecular sieves that are too small, and unformed powders. Therefore, they need to be screened, the large particles are crushed again, and sent back to the pelletizer together with the small particles for processing. The whole process involves a large number of material transfer operations, which are very cumbersome and labor-intensive for workers. Therefore, a more efficient and reasonable material handling system needs to be designed. Utility Model Content

DETAILED DESCRIPTION

[0018] Example

[0019] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3 As shown, the post-pelleting material processing system of this embodiment includes a first screening device 10, a crushing device 21 connected to the first screening device 10, a storage device provided below the first screening device 10, and a pelletizer 30 provided below the storage device; the discharge end of the crushing device 21 is connected to the storage device. Specifically, when in use, the molecular sieve microspheres produced by the pelletizer 30 are transferred to the first screening device 10 for screening, the large particles that do not meet the requirements are transferred to the crushing device 21 and crushed into powder and then sent to the storage device for temporary storage, the particles that meet the requirements are discharged and collected, and the small particles and powder are discharged into the storage device. When adding materials to the pelletizer 30, part of the materials in the storage device can be added to perform the pelletizing operation. In this way, the entire operation of converting powder to molecular sieve microspheres can be completed efficiently and automatically, which can significantly reduce and reduce the workload and labor intensity of workers, and automatically recycle the microspheres and powder that do not meet the requirements.

[0020] The first screening device 10 in this embodiment includes a shell 11, a first sieve plate 12 arranged in the shell 11, a second sieve plate 13 arranged below the first sieve plate 12, a first discharge hopper 14 connected to the side wall of the shell 11, a second discharge hopper 15 connected to the side wall of the shell 11, and a first discharge pipe 16 connected to the first discharge hopper 14; the aperture of the first sieve plate 12 is larger than the aperture of the second sieve plate 13; the first discharge hopper 14 is arranged above the first sieve plate 12; the second discharge hopper 15 is arranged above the second sieve plate 13; the first discharge pipe 16 is connected to the feed end of the crushing device 21. Specifically, large particles of molecular sieve microspheres will remain on the first sieve plate 12 and be discharged into the crushing device 21 through the first discharge hopper 14 and the first discharge pipe 16. Small particles of molecular sieve microspheres and micropowder will pass through the second sieve plate 13 and be discharged into the storage device. The molecular sieve microspheres that meet the requirements between the first sieve plate 12 and the second sieve plate 13 will be discharged through the second discharge hopper 15 and temporarily stored. It should be noted that the first screening device 10 is a vibrating screening device, so a vibration motor needs to be connected to the housing 11 to improve the screening efficiency.

[0021] In this embodiment, the first sieve plate 12 is tilted, with the side of the first sieve plate 12 near the first discharge hopper 14 lower than the opposite side. The second sieve plate 13 is tilted, with the side of the second sieve plate 13 near the second discharge hopper 15 lower than the opposite side. Specifically, the tilted first and second sieve plates 12, 13 facilitate material discharge.

[0022] The discharge end of the pulverizing device 21 in this embodiment is connected to a second screening device; the second screening device includes a housing 23, a third sieve plate 24 disposed within the housing 23, and a second discharge pipe 25 disposed at the lower end of the housing 23; the second discharge pipe 25 is connected to the storage device; the aperture of the third sieve plate 24 is the same as the aperture of the second sieve plate 13. Specifically, the powder discharged from the pulverizing device 21 must also be screened to ensure that its particle size meets the requirements. The pulverizing device 21 can be a conventional pulverizer or grinder, as long as the particle size of the discharged powder meets the requirements.

[0023] In this embodiment, the upper end of the box 23 is connected to the crushing device 21 via the support column 22. Specifically, the crushing device 21 itself generates continuous high-frequency vibration during operation. By connecting the crushing device 21 to the box 23, the crushing device 21 can vibrate the second screening device, thereby improving the screening efficiency.

[0024] The storage device in this embodiment includes a storage box 17 connected to the lower end of the housing 11, a third discharge pipe 18 provided at the lower end of the storage box 17, and a valve provided on the third discharge pipe 18; the third discharge pipe 18 is arranged to face the pelletizing machine 30. Specifically, the first screening device 10 and the second screening device are always in operation and discharging material, but the discharge rate is not constant. Therefore, the discharged material needs to be temporarily stored in the storage box 17. When it is needed, the valve on the third discharge pipe 18 is opened to allow the material to enter the pelletizing machine 30.

[0025] In summary, the post-pelletizing material processing system of this embodiment, when in use, transfers the molecular sieve microspheres produced by the pelletizer 30 to the first screening device 10 for screening, transfers the large particles that do not meet the requirements to the crushing device 21, crushes them into powder, and then sends them to the storage device for temporary storage, discharges and collects the particles that meet the requirements, and discharges the small particles and powder into the storage device. When adding materials to the pelletizer 30, part of the materials in the storage device can be added for pelletizing operation. In this way, the entire operation of converting powder to molecular sieve microspheres can be completed efficiently and automatically, which can significantly reduce and reduce the workload and labor intensity of workers, and automatically recycle the microspheres and powder that do not meet the requirements.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
