NOVELTY - The utility model claims a device for preparing graphene oxide powder, comprising a drying box body, a drying chamber, a collecting groove and a packing auger, the plurality of tray right ends are respectively installed in the drying chamber through a hinge shaft horizontally set at front and back direction; a gap is left between the tray and the right side wall of the drying chamber; the drying chamber is fixedly installed with a pushing element at the left upper position; the pushing element push rod is vertically set downwards; the left end of the plurality of trays are respectively hinged with an inclined pull rod; the right end of the inclined pull rod is hinged on the push element push rod. The utility model claims a graphene oxide powder preparation device, the push rod drives the tray from the horizontal state to the inclined state, pouring the oxidized graphene powder after drying, improving the graphene oxide powder collecting rate and bottom performance, improving the graphene oxide powder preparation speed.
