▎ 摘　　要

NOVELTY - A device comprises feeding device main body (1), preheating device main body (2), sedimentation device main body (3) and cooling device main body (4). The feeding device main body, preheating device main body, sedimentation device main body and cooling device main body are connected by electric closing door (5). The preheating device main body is provided with worm. The two ends of worm are connected with inner wall of preheating device main body through first bearing. One side of worm is provided with fan assembly. The outer portion of worm is sleeved with gear ring. The gear ring is fixedly connected with worm. The inner wall of top portion of preheating device main body is provided with first through hole. One side of gear ring is provided with gear. One side of gear is provided with motor. The top portion of preheating device main body is provided with sealing cover. The motor is fixedly connected with mounting plate. The top end of mounting plate passes through sealing cover. USE - Graphene growth device. ADVANTAGE - The device can make hot air in the pre-heating device main body uniformly distributed in the main body, so that preheating effect of graphite is better, thus replacing and repairing the motor in a convenient manner. The device allows the connecting plate to move downwards so that the limiting plate passes through the through-hole, and the bottom end of limiting plate moves to the limiting groove so as to allow the limiting inserting plate to be fixed relative to the sealing cover, thus avoiding limiting flashboard shaking in an effective manner.
