Abstract

The invention discloses a freeze-drying device for aminated graphene production, comprising a closing mechanism, moving mechanisms for driving the device to move, a storage mechanism and a fixing mechanism. The moving mechanisms are mounted on the two sides of the closing mechanism. By providing a recovery mechanism, condensate water in a closed box enters a collection box through water permeableholes and then enters a water tank through a drain pipe, so that the condensate water can be recycled, and the practicability of the device is improved; by providing a cooling mechanism, the contact area of a circulating pipe and a support table is increased by adopting a U-shaped structure, so that the cooling effect of the device is effectively improved; and by providing a stirring mechanism, afirst motor and a second motor cooperate to drive a stirring rod to perform lifting type stirring, so that the stirring rod can comprehensively stir aminated graphene in a storage box, the aminated graphene can be uniformly freeze-dried, and therefore the time required for complete freeze-drying of the aminated graphene is shortened.

Description

technical field [0001] The invention relates to the technical field of aminated graphene production, in particular to a freeze-drying device for the production of aminated graphene. Background technique [0002] Graphene is a carbon atom with sp 2 The hybrid orbitals form a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. The common powder production methods of graphene are mechanical exfoliation method, redox method, and SiC epitaxial growth method, and the film production method is chemical vapor deposition (CVD). Aminated graphene is also a kind of graphene. [0003] A freeze-drying device is needed in the production process of aminated graphene, and the existing freeze-drying device has the...
