NOVELTY - The utility model claims an ultrasonic graphene preparation device, relating to graphene preparation technology field, comprising a base, the upper end of the base is provided with a furnace body, and the upper end of the base close to one side of the furnace body is provided with a vacuum pump; one side of the vacuum pump is provided with a processing box; the upper end of the furnace body is provided with a furnace cover; the upper end of the furnace cover is connected with a foam discharging pipe; one end of the foam discharging pipe is connected with a foam pump on the upper surface of the processing box; the inner part of the furnace body is provided with an inner cylinder; and a vacuum cavity is set between the furnace body and the inner cylinder. The utility model solves the problem that the traditional ultrasonic processing graphene, the sound wave is harmful to the body of the worker, and through the action of foam suction disc matched with the foam pump, the flocculent graphene generated in the ultrasonic treatment can be extracted, which not only improves the graphene ultrasonic treatment effect in the inner cylinder; and it can carry out secondary treatment to the flocculent graphene, so that the ultrasonic treatment efficiency of graphene is higher.
