▎ 摘　　要

NOVELTY - Base metal flake heating device for preparing graphene by chemical vapor deposition (CVD) method comprises a bottom plate (1) and a top plate (2). The top plate is arranged vertically above the bottom plate in parallel. Support column (3) is provided between the bottom side of the top plate and the bottom plate. The middle part of the top side of the bottom plate is fixedly connected with a bottom support tube (5). The board body of the top board is provided with a plurality of sliding holes distributed in a divergent manner. The two ends of the sliding rod (6) are respectively fixedly connected with a bottom limit plate and a top limit plate. The top side of the top limit plate is fixedly connected with a column. The top of the upright column is fixedly connected with a supporting foot, which is provided with a card hole. A card post is provided in the card hole. The top of clamping column extends to top side of the supporting foot and fixedly connected to the limiting side column. USE - Used as base metal flake heating device for preparing graphene by chemical vapor deposition (CVD) method. ADVANTAGE - The device: has strong applicability, good carrying effect on the carrying container, and good heating effect; is easy to use; and meets people's use needs in production and life. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the base metal flake heating device for preparing graphene by chemical vapor deposition (CVD) method.
