▎ 摘　　要

NOVELTY - The device has a second spring whose two ends are sleeved on a second limit post. The second limiting posts are welded vertically on the rear end of the clamp block and the inner wall of the chute of an inlet (4). A plugging device consists of a plug, a support block, a first sliding bar, a cylindrical rod, a first spring, a limit block, a rectangular frame and Composed of anti-slipping. The plug is fixed in the inlet, one side of the plug is welded with the support block, and the support block is vertically welded with the cylindrical rod. The first sliding strip is welded on both sides of the cylindrical rod, and the upper portion of the cylindrical rod is inserted into the rectangular block. The upper end of the rectangular frame is vertically welded to the inner wall of the inlet. The upper portion of the cylindrical rod is sleeved with the first spring, and the upper end of the cylindrical rod is welded with the anti-dropping block. USE - Original refinement classification storage device for graphene production. ADVANTAGE - The conveying pipe is fixed in the entrance of the storage barrel, so that the conveying pipe does not loose when the graphene is conveyed, so that the graphene conveying and storing process is safer, more reliable and efficient. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the original refinement classification storage device for graphene production. Base (1) Storage barrel (2) Fixing frame (3) Inlet (4) Delivery pipe (5)
