▎ 摘　　要

NOVELTY - Device comprises a heating furnace body (1) and a reaction chamber body (2) and a feeding device (3) fixedly disposed in the reaction chamber body, a transportation material device (4), and a material collecting device (5). The transport material device is a platform disposed parallel to the inner wall of the reaction chamber. The upper end of the platform is in contact with the feeding device. The transportation material device is disposed under the platform, The reaction chamber includes an inlet end disposed at a lower end and an outlet end disposed at an upper end, and the reaction chamber is further coupled with a rotating device. USE - The device is useful for preparing graphene copper powder. ADVANTAGE - The device: avoid the problem that the material is bonded at a high temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene copper powder by using the device comprising (i) horizontally placing initial position of the reaction chamber, adding and the copper powder in the feeding device, (ii) opening the mechanical pump at the outlet end to pump air, and passing the shielding gas argon gas and the reducing gas hydrogen gas from the inlet end, (iii) starting the heating furnace body, raising the temperature in the reaction chamber to reach the target temperature, and introducing carbon source methane, and (iv) starting the rotating device to increase the angle between the reaction chamber and the horizontal plane, and the copper powder leaks from the feeding device to the material transport device, reacting with the methane cracking product, and the product falls through the collecting material device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for preparing graphene copper powder.
