NOVELTY - The utility model claims a device used for CVD for continuous graphite alkene preparing, comprising tube-type furnace and quartz pipe, the pipe through the quartz tube type furnace, two end the quartz pipe is respectively equipped with the first flange and the second flange, and the first flange set with outer side, inner side of the first flange set with the first bracket, outer side of the second flange provided with an air outlet, the inner side of the second flange set with the second bracket, the first bracket and the second bracket to the opposite side respectively set with the first rolling shaft and the second rolling shaft, a flexible substrate is wound on the roller of the first traction and to the second roller, motor driving the second rotary roller, the first roller and the second roller are as can disassemble type roller. This utility model with new type furnace as base, by using continuous substrate for avoiding repeatedly heating and cooling the substrate and change process, increase efficiency of graphene prepared by method heating area and, at the same time reducing can consume, increase energy use rate.
