▎ 摘　　要

NOVELTY - The device has a drying cylinder (1), where the inner cavity of the drying cylinder is provided with an inner and outer drying mechanism (2). The left side of the inner drying mechanism is provided on the left side with a limiting supporting mechanism (3). The bottom of the dried cylinder is fixedly installed with a discharge port (4), and the bottom of drying cylinder near the bottom is fixed with a feeding port (5) close to the top. The inner and the drying mechanism comprises an inner cylinder (201) located in the inner chamber of the dryer (1). A fixing cylinder (202) is fixed on the inner left side, where the left side is jointed with the left right side of inner cavity. The left surface of inner cylinder is connected with a conveying port (203) and a limiting ring (204) is installed on the outer side of conveyor (203). USE - Device for preparing drying ultra-wide type AFG material e.g. graphene material and graphene of hot two-dimensional material. ADVANTAGE - The inner cylinder plays a role of supporting, so that the inner cylinder rotates more stable, and through the matching between the handle and the connecting plate and the limiting rod and the moving ring. The drying device for preparing ultra-wide type AFG material, effectively solves the problem that it is easy to make the graphene of the heating cylinder to cause the problem of the drying of the graphene is not sufficient. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a device for preparing drying ultra-wide type AFG material. 2Inner and outer drying mechanism 201Inner cylinder 202Fixing cylinder 203Conveying port 204Limiting ring 205External rotating heating mechanism 206Internal stirring heating mechanism
