NOVELTY - The utility model claims a storage and transportation barrel for storing graphene powder, comprising a barrel body main body; the bottom of the barrel body main body is provided with a first lower cover; the first lower cover is provided with a vacuum one-way valve; the vacuum one-way valve is provided with a filter cloth; when the storage and transportation barrel is in graphene powder packaging condition; after the vacuum one-way valve is connected with the external vacuum generating device, the vacuum negative pressure environment can be formed in the barrel main body. The utility model, in the process of packaging graphene powder, the vacuum one-way valve set on the barrel bottom wall of the storage and transportation barrel can make the barrel body form a vacuum negative pressure environment, so as to effectively avoid the dust pollution caused by floating flying of graphene powder with small density, reducing the material loss caused by graphene powder flying.
