▎ 摘　　要

NOVELTY - The method involves fixing a furnace body (1) and an argon storage shell (2). The furnace body is fixedly embedded in the top of the argon storage shell. A trigger type exhaust mechanism (3) is provided with the top surface of the furnace body. A driving mechanism (4) is arranged between the bottom surface and the inner side of the argon storage shell. The driving mechanism is provided in transmission connection with an upper sealing component (5) and a rotary placing mechanism (6) from bottom to top. A stirring mechanism (7) is mounted on the upper sealing component. A lower sealing component (8) is mounted on the rotary placing mechanism. A roasting crucible (9) is placed on the roof of the top side of the rotary placing mechanism. USE - Method for forging high performance aluminum alloy used in material preparation technology field. Can also be used in research of mechanical properties, e.g. mechanical strength. ADVANTAGE - The method enables effectively simplifying carboxylating graphene preparation step without transferring, reduces vacuumizing operation times, improves drying efficiency of mixed powder and input efficiency of argon gas, so as to effectively improve preparation efficiency of carboxylated graphene with needle-shaped anatase titanium oxide coating on a surface. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a trigger type exhaust mechanism. 1Furnace body 2Argon storage shell 3Trigger type exhaust mechanism 4Driving mechanism 5Upper sealing component 6Rotary placing mechanism 7Stirring mechanism 8Lower sealing component 9Roasting crucible
