[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: a centrifugal screening device for kaolin processing, comprising a main mounting box 1, a secondary mounting box 2 installed at the bottom of the main mounting box 1, and the secondary mounting boxes 2 being installed in a stacked structure; both the main mounting box 1 and the secondary mounting box 2 are provided with screening chambers 3, and screening structures are installed inside the screening chambers 3; one end of both the main mounting box 1 and the secondary mounting box 2 is fixedly connected to a feed pipe 5, and the top of the feed pipe 5 is fixedly connected to a feed hopper 6; both the main mounting box 1 and the secondary mounting box 2 are provided with guide plates 9 at the bottom, and the guide plates 9 extend outward toward the outside of the main mounting box 1 and the secondary mounting box 2 to form a discharge trough 10, and the discharge trough 10 at the bottom of the main mounting box 1 and the feed hopper 10 at the end of the secondary mounting box 2 are connected to the feed hopper 6. The buckets 6 are aligned with each other. The main mounting box 1 and the auxiliary mounting box 2 are provided with a discharge chamber 4 at the end away from the feed pipe 5. The top of the auxiliary mounting box 2 is fixedly connected to the upper mounting frame 7, and the bottom of the auxiliary mounting box 2 is fixedly connected to the lower mounting frame 8. The bottom of the main mounting box 1 is fixedly connected to the lower mounting frame 8. The lower mounting frame 8 at the bottom of the main mounting box 1 and the upper mounting frame 7 at the top of the auxiliary mounting box 2 are connected to each other. The main mounting box 1 and the auxiliary mounting box 2 are connected to each other through the upper mounting frame 7 and the lower mounting frame 8 at their top and bottom to form a stacked structure. The discharge chamber 4 is fixedly connected to the buffer plate 11. The buffer plate 11 and the discharge chamber 4 are both installed with bearings. The bottom of the discharge chamber 4 is provided with a discharge pipe 12.

[0026] First, the kaolin particles that have undergone preliminary crushing are fed into the feed pipe 5 from the top of the main mounting box 1 through the feed hopper 6. A screw rod 16 is installed inside the feed pipe 5. The screw rod is driven by a pulley connected to its end, so that it rotates continuously inside the feed pipe. As the screw rod 16 rotates, the kaolin material is evenly pushed into the screening chamber 3 inside the main mounting box 1.

[0027] After the kaolin enters the screening chamber 3 of the main installation box 1, it undergoes preliminary screening through the built-in screening structure. The screening structure uses cylindrical screens 14 with different aperture sizes to separate fine kaolin particles smaller than the aperture size of the cylindrical screen 14. Impurities and lumps larger than the aperture size of the cylindrical screen 14 remain on the cylindrical screen 14 for further processing. Qualified fine particles fall from the screening structure onto the guide plate 9. The guide plate is designed with a certain inclination angle to ensure that the material can move smoothly downwards under the action of gravity.

[0028] The bottom of the guide plate 9 extends to form the discharge trough 10. The vibration generated during the operation of the entire device will further push the fine kaolin particles to slide along the plate until they enter the discharge trough 10. After the material slides into the discharge trough 10, it will be discharged directly from the main installation box and fall into the feed hopper 6 at the end of the auxiliary installation box 2, ready to enter the next round of screening.

[0029] The kaolin discharged from the main installation box 1 re-enters the auxiliary installation box 2 and undergoes secondary screening through the same screening structure. The screening process in the auxiliary installation box 2 is similar to that in the main installation box, but since it has already undergone screening once, the remaining impurities and large particle clumps are more easily separated. At the same time, this step can supplement the screening of qualified particles that were not completely separated in the first screening, further improving the purity.

[0030] Finally, large particles or agglomerated materials that fail to pass through the screening aperture will be collected in the discharge chamber 4 and discharged uniformly through the discharge pipe 12. The qualified kaolin after each screening will continue to slide into the next feed hopper 6 for repeated screening until the required purity is met.

[0031] Example 2: Based on Example 1, a screening structure is also disclosed, the specific structure of which is as follows: The screening structure includes fixed partitions 13 installed at both ends of the screening chamber 3, and a cylindrical screen 14 is fixedly connected between the two fixed partitions 13. The diameter of the top cylindrical screen 14 is larger than that of the bottom cylindrical screen 14. A spiral rod 16 is installed at one end of the cylindrical screen 14, and the spiral rod 16 is rotatably connected to the inside of the feed pipe 5. An equally spaced, ring-shaped stirring strips 15 are rotatably connected inside the cylindrical screen 14. The stirring strips 15 are installed on a rotating shaft, and the end of the rotating shaft away from the spiral rod 16 passes through the middle of the buffer plate 11 and the discharge chamber 4. The rotating shaft is installed inside the bearing between the discharge chamber 4 and the buffer plate 11. At the same time, pulleys are fixedly connected to the ends of the spiral rod 16 and the rotating shaft.

[0032] The screening structure is supported by fixed partitions 13 installed at both ends of the screening chamber 3. A cylindrical screen 14 is set between the fixed partitions, and kaolin is fed into the cylindrical screen 14 through the feed pipe 5. One end of the cylindrical screen is connected to the screw rod 16, and the other end is fixed between the buffer plate 11 and the discharge chamber 4 through a bearing. The rotating shaft is driven to rotate by a belt pulley, which drives the stirring bar 15 inside the cylindrical screen to rotate and stir at high speed.

[0033] The stirring bars 15 are distributed in a ring at equal intervals. During rotation, they can continuously turn and disperse the kaolin particles in the cylindrical screen, accelerating the process of the particles passing through the aperture of the cylindrical screen 14. Particles smaller than the aperture of the cylindrical screen 14 fall quickly to the guide plate 9 during the tumbling process. Particles or impurities larger than the aperture are retained in the cylindrical screen and gradually pushed to the discharge chamber 4. During the screening process, impurities or lumps that do not meet the specifications will be sent to the discharge chamber 4 with the rotation of the stirring bars. The bottom of the discharge chamber is equipped with a buffer plate 11 to reduce the impact of lumps or impurities on the inner wall of the discharge chamber and avoid damage to the equipment. The impurities are finally discharged into the external collection container through the discharge pipe 12.

[0034] After screening, qualified kaolin falls through the cylindrical screen 14 onto the guide plate 9. The inclined design and vibration function of the guide plate further push the particles downward and finally slide into the discharge chute 10. The qualified kaolin particles enter the next feed hopper through the discharge chute and enter the next round of screening to ensure that the purity meets the expected standard.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium.
