[0016] In summary, the technical effects and advantages of this invention are as follows:

[0017] 1. In this invention, when coarsely grinding silica particles, the silica particles are placed in a processing box. Guided by a guide block, the silica particles fall between the active roller and the driven roller. The drive motor starts, causing the active roller and bottom gear to rotate. The bottom gear drives the driven gear to rotate, causing the driven roller to rotate. The active roller and driven roller work together to coarsely grind the silica particles. When fine grinding is required, the threaded sleeve is rotated, causing it to move away from the driven gear on the threaded rod. Under the spring force, the driven gear slides on the round rod and aligns with the external gear. Then, the U-shaped rod is unlocked, and the pulling block is pushed, causing the U-shaped rod to slide on the fixed block. This allows the two sliding blocks to slide within the sliding holes, moving the driven roller towards the active roller, causing the driven gear to mesh with the external gear. Finally, the U-shaped rod is locked, facilitating fine grinding of the silica particles. This method is simpler, more convenient, and more practical.

[0018] 2. In this invention, when it is necessary to unlock the U-shaped rod, pull the pull tab, and the anti-detachment cap will drive the locking rod to move away from the fixed block, thus unlocking the U-shaped rod. Then, pull or push the pull block to move the U-shaped rod, which facilitates the adjustment of the driven roller. After the adjustment is completed, release the pull tab, and under the tension of the tension spring, drive the locking rod to move towards the fixed block and insert it into the lock hole, locking the U-shaped rod, making it more convenient to use.

[0019] 3. In this invention, during use, silica particles are placed into the filter box, cleaning solution is added to the mounting shell, the stirring motor is started, driving the stirring rod to rotate and stir the cleaning solution. Simultaneously, the motor starts, driving the gears to rotate. With the engagement of the gears, the motor drives the T-shaped slider to slide within the slide rail via the connecting rod, causing the flipping rod to move and agitate the silica particles. With the assistance of the stirring motor, impurities on the silica particles are cleaned. Then, the dial is turned, causing the filter box to rotate around the clamping block with the assistance of the rotating block. The filter box filters the silica particles, and then the silica particles are poured into the processing box. This facilitates cleaning and filtering of the silica particle core and makes it convenient to use. Attached Figure Description

[0042] The working principle of this invention is as follows: When coarsely grinding silica particles, the silica particles are placed in the processing box 1 and fall between the driving roller 2 and the driven roller 3 via the guide block 8. The drive motor 403 starts, driving the driving roller 2 and the bottom gear 40 to rotate. The bottom gear 40 drives the driven gear 402 to rotate, causing the driven roller 3 to rotate. With the cooperation of the driving roller 2 and the driven roller 3, the silica particles are coarsely ground. When fine grinding is required, the threaded sleeve 702 is rotated, causing the threaded sleeve 702 to move away from the driven gear 403 on the threaded rod 703. The movement of the U-shaped rod 100, under the elastic force of the spring 70, causes the driven gear 402 to slide on the round rod 601 and align with the external gear 401. Then, the U-shaped rod 100 is unlocked, and the pulling block 101 is pushed, causing the U-shaped rod 100 to slide on the fixed block 102. This allows the two sliding blocks 60 to slide in the sliding hole, causing the driven roller 3 to move towards the driving roller 2, so that the driven gear 402 meshes with the external gear 401. The U-shaped rod 100 is then locked, which facilitates the fine grinding of silica particles. It is simpler and more convenient to use, and has good practicality.

[0043] When it is necessary to unlock the U-shaped rod 100, pull the pull tab 1201. The anti-disengagement cap 1103 drives the locking rod 1101 to move away from the fixing block 102, thus unlocking the U-shaped rod 100. Then, pull or push the pull block 101 to move the U-shaped rod 100, which facilitates the adjustment of the driven roller 3. After the adjustment is completed, release the pull tab 1201. Under the tension of the tension spring 120, the locking rod 1101 moves towards the fixing block 102 and is inserted into the locking hole 1102, locking the U-shaped rod 100 and making it more convenient to use.

[0044] In use, silica particles are placed into the filter box 501, and cleaning solution is added to the mounting shell 50. The stirring motor 140 is started, driving the stirring rod 1401 to rotate and stir the cleaning solution. At the same time, the motor 130 is started, driving the gear 1301 to rotate. With the cooperation of the gear 1302, the motor 130 drives the T-shaped slider 903 to slide in the slide rail 902 through the connecting rod 901, causing the flipping rod 90 to move and flip the silica particles. With the cooperation of the stirring motor 140, impurities on the silica particles are cleaned. Then, the dial 502 is turned, causing the filter box 501 to rotate around the clamping block 503 with the cooperation of the rotating block 504. The filter box 501 filters the silica particles. Then, the silica particles are poured into the processing box 1, which facilitates the cleaning and filtering of the silica particle core and is convenient to use.
