Carbon nanotube powder semi-finished product storage device

The utility model discloses a carbon nano tube powder semi-finished product storage device which structurally comprises a supporting stand column, an observation window, a fixing transverse rod, a buffering and damping mechanism, a thermometer, a barometer, a storage barrel, a fixing bolt, a sealing top cover and a top end cover plate. According to the carbon nano tube powder semi-finished product storage device, the carbon nano tube powder is structurally placed in the storage barrel to bear force, and the supporting stand columns are matched with the fixing transverse rods to support the carbon nano tube powder; furthermore, a buffering and damping mechanism connected to the lower end of the supporting stand column is matched and fixed through an internal mounting seat, and a second meshing plate at the lower end is matched with rotating gears at the two ends for driving to perform displacement buffering; and a second spring contracts towards the upper end to achieve preliminary buffering, and a buffering s
