Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, and in particular to a drying device for producing graphene powder materials. Background Art

[0002] Graphene is a new material with hybrid connected carbon atoms tightly stacked into a single-layer two-dimensional honeycomb lattice structure. It has excellent optical, electrical and mechanical properties and has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery. Graphene powder materials need to be dried during the production process. The existing drying equipment keeps graphene in a static state during the drying process and can only dry the surface. The accumulation of graphene leads to incomplete drying inside or increased drying time, which reduces the drying efficiency and quality. The wet graphene will adhere to the inner wall of the box, resulting in graphene residue in the box and incomplete discharge, thus wasting graphene. Utility Model Content
