The limit block contacts the surface of the rotating plate, and the rotating plate is limited in one direction by the limit block.

[0014] The present invention provides a silicon material circulation drying device, which has the following beneficial effects:

[0015] (1) In this invention, the L-shaped frame moves toward the silicon material box, which drives the pulley frame to move toward the silicon material box. The pulley frame contacts the silicon material box to adjust the position of the silicon material box, ensuring that the silicon material box can accurately enter the fin heating device to prevent heat loss during heating. The downward movement of the slide bar will drive the rotating plate to rotate, and the rotation of the rotating plate will drive the connecting plate to rotate upward. The upward rotation of the connecting plate will adjust the position of the silicon material box to prevent the device from colliding with the fin heating device during the rising process due to inaccurate alignment, posing a safety hazard.

[0016] (2) In this invention, the movement of the trapezoidal block toward the drainage hole will push the sealing plate downward, and the downward movement of the sealing plate will seal the drainage hole to prevent the drainage hole from opening during the drying process, causing heat to flow out through the drainage hole, resulting in heat loss and reduced drying efficiency. The elastic force of the No. 5 spring drives the sliding long plate to reset, and the reset of the sliding long plate will push the liquid at the bottom of the silicon material box toward the drainage hole, thereby improving the drainage effect.

[0017] (3) In the present invention, the connecting rod moves toward the inner wall of the silicon material box, which drives multiple scraping plates to move toward the inner wall of the silicon material box. The scraping plates move toward the inner wall of the silicon material box to scrape off the liquid on the inner wall of the partition, thereby preventing the liquid from remaining on the inner wall of the partition and affecting the drying effect. The upward movement of the rotating plate drives the partition upward. When the short rod is separated from the rotating plate, the partition is reset under its own gravity. The vibration generated by the reset of the partition will shake off the liquid attached to the silicon material, thereby improving the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
