Continuous full-automatic control wrapping system for graphene powder

Abstract

The invention discloses a continuous full-automatic control wrapping system for graphene powder. The system comprises a wrapping mechanism, an operating platform, an independent electrical control cabinet and a stepped supporting plate; and one side of the operating platform is rotatably connected with the stepped supporting plate. According to the system provided by the invention, a screw feederis provided with a screw feeding rod extending to the inner wall of the thick end of a special-shaped quartz furnace tube, and the outer wall of the thin end, close to a collection tank, of the special-shaped quartz furnace tube is provided with a radio frequency coil, so that the above structure can shorten the preparation process time of the material; wrapping of the graphene powder is completedthrough heating and cooling of the radio frequency coil and the inclined wrapping mechanism; quartz baffles are welded in the special-shaped quartz furnace tube, polytetrafluoroethylene strips extending to the inner wall of the special-shaped quartz furnace tube and adhering to the quartz baffles are fixed at the inner wall of a pair of magnetofluids, in the process of collision of the polytetrafluoroethylene strips and the quartz baffles, the powder material is prevented from being agglomerated into a block, and therefore the surface properties of the powder material are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of graphene powder coating material equipment, in particular to a continuous automatic control graphene powder coating system. Background technique [0002] For the existing carbon material coating equipment on the market, vacuum atmosphere sintering equipment is mostly used. The matrix powder material is mainly put into the quartz tube, and after the carbon material film is grown on the matrix through reaction, due to the high temperature in the quartz chamber, it is necessary to carry out the sintering process first. After cooling down, put the new matrix material into the sample after taking the sample, and then carry out the temperature rise reaction, and the preparation of the target material is cycled in turn. This further prolongs the process time for preparing the material, and the repeated heating and cooling requires a large power consumption, which greatly increases the preparation cost. [0003]...

[0003] In addition, the metal powder is easy to connect into a block due to agglomeration at high temperature, which is not conducive to the full contact of the reaction gas. The carbon atoms produced by cracking will deposit and diffuse on the block material to form a film. The particle size is large and the specific surface area is relatively small, which affects the surface properties of carbon-coated materials
