NOVELTY - The utility model claims a graphene preparation technology field, relating to an air inlet device of graphene powder production device and graphene powder production device. It comprises an air inlet pipe, the lower end of the air inlet pipe is connected with an air outlet structure for dispersing the gas, the air inlet pipe is further connected with a lifting device for driving the air inlet pipe to lift. The utility model drives the air inlet lifting through the lifting device, so that the air outlet depth position of the air inlet device is adjustable in the production process, and the operation is convenient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene powder production device.
