NOVELTY - The utility model claims a fusion liquefying device for preparing graphene, comprising a first reaction kettle and the second reaction kettle, the first reaction kettle and the second reaction kettle is filled with rock wool, the upper surface of the first reaction kettle by bolt is fixed with an upper cover; The utility model claims an electric heating pipe to make the temperature in the second reaction kettle is increased, raw material under the combined action of high temperature and stirring to make the raw material fully and quickly liquefying, rock wool and prevent the heat generated by the electric heating tube of spreading, effectively reduces the loss of the heat. it greatly improves the utilization rate of the resource, increase caused by air pressure in the second reaction kettle, when the air pressure in the second reaction kettle reaches a certain level, the air pressing supporting plate away from the choke plug groove, the gas overflowing from the groove and a through hole, an air purifier of the harmful substance and odour in the gas cleaning, effectively prevents the gas from polluting the environment, situation also prevents the crock.
