[0052] Meanwhile, when the slider 611 is in transition from the highest point of the arc-shaped convex end 520 to the annular slide 510, the slider 611 gradually moves downward and synchronously drives the connecting block 621 to move downward through the connecting frame 612, at this time, the spring two 627 first releases its elastic force, so that the slide column 622 and the mounting column 631 synchronously move downward with the connecting block 621, while the jacking column 624 is in a static state, in this process, the connecting rod 632 gradually separates from the top constraint 637 and rotates, so that the side support plate 634 rotates into the mounting groove 628, when the connecting rod 632 moves downward with the mounting column 631 to contact the bottom constraint 636 again, the bottom constraint 636 can drive the connecting rod 632 to continue to rotate, ensuring that the connecting rod 632 can drive the side support plate 634 to be fully hidden in the mounting groove 628 through the guide block 633 and the guide groove 635, providing a prerequisite for the re-entry of the jacking column 624, and the side support plate 634 can form a spiral flow field inside the reaction combination 300 by unfolding and folding, and this unique flow field form makes the reaction reagent, reaction gas and reaction heat better enter the inside of the fragments along a specific path.

[0053] The bottom constraint 636 preferably adopts a cylindrical structure with a U-shaped cross-section with a hole in the middle, and the top constraint 637 preferably adopts a cylindrical structure with a convex-shaped cross-section with a hole in the middle.

[0056] The rotating frame 420 can support the reaction frame 310 in the recycling tank body 100 in a suspended state in the recycling tank body 100 by cooperating with the support protrusion 440, so that the debris on the reaction frame 310 can be fully pyrolyzed and gasified, and the device can recover high-quality fibers; when the recovered fibers on the reaction frame 310 need to be recovered, the reaction frame 310 at the top of the recycling tank body 100 can be lifted first, and then the rotating frame 420 below it is rotated to an angle close to the recycling tank body 100, so that the reaction frame 310 below the rotating frame 420 can be conveniently hoisted, improving the recovery quality and recovery efficiency of the device.

[0057] In a preferred embodiment, the limiting block 430 can limit the rotation angle of the rotating frame 420, so that it changes from a vertical state to a horizontal state, or from a horizontal state to a vertical state, so as to ensure that the rotating frame 420 can effectively and sufficiently support the reaction frame 310.
