Abstract

The invention discloses a preparation equipment of graphene nanoplatelets. The equipment comprises a mixing chamber, a grinding chamber and a calcining chamber, wherein the mixing chamber, the grinding chamber and the calcining chamber are fixedly connected from the upper part to the lower part in sequence; a first cavity is formed inside the mixing chamber; a feeding opening is formed in the topof the mixing chamber; a rotating shaft penetrates through the center of the top of the mixing chamber; a second cavity is formed inside the grinding chamber; a stirring rack is fixedly connected withthe mixing chamber section of the rotating shaft; the stirring rack comprises a stirring rack body and two cross rods; crushing teeth are arranged on the stirring rack body and the two cross rods; agrinding roller is arranged in the grinding section of the rotating shaft; a third cavity is formed inside the calcining chamber; a calcining vessel is arranged in the third cavity; a spray gun at thetop of the left side of the calcining chamber penetrates through the third cavity; a gas supply pipe is arranged at the top of the right side of the calcining chamber. The equipment can prepare graphene nanoplatelets in bulk with low cost, and solves the problems of low yield, small size and high cost in the existing graphene preparation technology.

Description

technical field [0001] The invention relates to the field of nanomaterial production equipment, in particular to a preparation equipment of graphene microchips. Background technique [0002] Graphene, as the thinnest, strongest, and strongest new type of nanomaterial found so far, is called "black gold" and is the "king of new materials". Scientists even predict that graphene will "completely change the 21st century" ". Graphene is a single-layer sheet structure material composed of carbon atoms. Because of its high strength, high thermal conductivity, high electrical conductivity and high specific surface area, it has attracted extensive attention from researchers. A disruptive new technology and new industrial revolution sweeping the world. [0003] The exfoliation of graphene microflakes from expanded graphite can be accomplished by existing technical means, but limited by production cost and product performance factors, there is still no industrial application. Theref...
