NOVELTY - Graphene film drying device includes left drying chamber provided with first outer hood and first inner hood; first hot air return passage formed between first outer hood and first inner hood, first outer hood cover provided outside of first inner hood; and first air outlet duct and first return air duct provided at top portion of left drying chamber; and right drying chamber provided with second outer hood and second inner hood; second hot air return passage formed between second outer hood and second inner hood; second outer hood cover provided outside of second inner hood; and second outlet air duct and second return air duct provided on top portion of right drying chamber. USE - Graphene film drying device. ADVANTAGE - The gas heated by electric heating box enters left drying chamber from right drying chamber through heat recovery passage, and gas in left drying chamber is heated into right drying chamber through another heat recovery passage, so that heat can be recycled. The rolling conveyor can turn film over so that film can be uniformly dried. DETAILED DESCRIPTION - Graphene film drying device comprises left and right drying chambers (1, 2). The left drying chamber is provided with first outer hood and first inner hood, such that first hot air return passage is formed between first outer hood and first inner hood; and first outer hood cover provided outside of first inner hood; and first air outlet duct and first return air duct provided at top portion of left drying chamber. The right drying chamber is provided with second outer hood and second inner hood, such that second hot air return passage is formed between second outer hood and second inner hood; second outer hood cover provided outside of second inner hood; and second outlet air duct and second return air duct provided on top portion of right drying chamber. The first outer hood is connected to electric heating box inlet through first air outlet duct. The electric heating box outlet is connected to second inner air hood through second return air duct. The second outer air hood is connected to inlet of circulating fan (3) through second air outlet duct. The circulating fan outlet is connected to first inner hood through first return air duct. The device also includes first rolling conveyor provided below first inner hood, and second rolling conveyor provided below second inner hood. The first rolling conveyor comprises feed roller (7) at right entrance of left drying chamber and first drive roller (10) below feed roller, and steering roller (6) provided between feed roller and first drive roller. The second rolling conveyor includes second drive roller at entrance of right drying chamber, discharge roller provided at right side exit of right drying chamber, and guide roller (8) provided at second drive roller and discharge roller. The first and second drive rollers are in same horizontal position. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of graphene film drying device.
