▎ 摘　　要

NOVELTY - The device has a sealing mechanism (1) whose two sides are provided with a moving mechanism (2). The sealing mechanism is provided with a storage mechanism (3). Two sides of the storage mechanism are provided with a fixing mechanism (4). A recycling mechanism (5) is fixed on the sealing mechanism. A cooling mechanism (6) is installed below the sealing mechanism. A stirring mechanism (7) is fixed above the sealing mechanism. The recycling mechanism is provided with a collecting box that is formed with a water permeable hole. An outer side of a rotating shaft is fixed with a stirring rod. USE - Freeze-drying device for production of aminated graphene. ADVANTAGE - The practicability of the device is improved. The contact area of the circulating pipe and the supporting table is increased by setting the cooling mechanism. The cooling effect of the device is effectively improved. By setting the stirring mechanism, the first motor and the second motor cooperate to drive the stirring rod to lift and stir, so that the stirring rod fully stir the aminated graphene in the storage tank, and the aminated graphene is uniformly freeze-dried, to shorten the time for completely freeze-drying the aminated graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of freeze-drying device for production of aminated graphene.
