▎ 摘　　要

NOVELTY - The device has a tank (1) in which one side is connected to a vacuum machine (2) through a pipe, and the other side is connected with a nitrogen transfer machine (3) through a pipe. A through hole is opened in a middle portion of the bottom end of the tank, and one end of the third spring are welded and fixed to a bottom wall of an interlayer. The other end is welded and fixed to one side of the fixing block, and the other side of the fixing block is provided with a groove. A bearing is welded and fixed in the groove, and a rotating shaft (11) is inserted and fixed in the middle of the bearing. A toothed sleeve is welded and fixed on the inner wall of the hole. The top end of a hydraulic rod (8) is fixed with a tray (9) by screws, and the middle part of the tank is fixed with a sealing block (4) by screws. The through hole is provided with an inner wall which is connected to an opening and closing plate through a hinge. USE - Storage device for finished graphene product. ADVANTAGE - The disk is rotated so that the through hole on the fixed disk and the through hole on the sealing block are aligned with the through hole on the case, thus facilitating the release of the graphene glass tube without causing damage to the glass tube. The storage device automatically opens and closes under the action of the second spring by the opening and closing plate on the sealing block, so that the box can ensure a certain sealing in the case of easy handling, so that the graphene in the box is not oxidized. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the storage device for the graphene finished product.
