Embodiment 1

[0031] A device using method for preparing graphene by jet pulverization, the steps are as follows:

[0032] ①Put the graphene raw material and steel powder raw material into the mixed material feeding hopper and steel powder feeding hopper respectively, adjust the feeding speed of the mixed material feeding hopper and steel powder feeding hopper so that the mass ratio of the feeding material is 1 :1;

[0033] ②The graphene raw material and steel powder are collided and rubbed in the jet mill, and the graphene raw material is crushed. When the graphene powder and steel powder pass through the holding tube, the steel powder is adsorbed to the wall of the holding tube by the electromagnet, while the graphene The powder enters the cyclone separator, the qualified particles enter the pulse filter to be intercepted, and the unqualified particles enter the recovery chamber;

[0034] ③The steel powder on the wall of the containing pipe can be discharged from the discharge port throu...

Abstract

The invention discloses a device for preparing graphene through jet milling. The device comprises a mixture feed hopper, a steel powder feed hopper, a jet mill, a cyclone separator, a recovery chamber, a pulse filter and an exhaust fan. The mixture feed hopper and the steel powder feed hopper are connected to the jet mill. The cyclone separator is connected with a discharge port of the jet mill through a pipeline. The recovery chamber is connected to the lower portion of the cyclone separator. The pulse filter is connected with the upper end of the cyclone separator through a pipeline. The exhaust fan is connected with an exhaust port of the pulse filter. Graphene raw materials are subjected to pretreatment. Breakable sodium chloride and magnesium chloride are led in through intercalators. Smashing of graphene is facilitated. The smashing effect is improved. The device has the advantages of being simple in structure, easy to operate, good in smashing effect and the like.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a device and method for preparing graphene by jet pulverization. Background technique [0002] Graphene is a two-dimensional crystal composed of carbon atoms with only one atomic thickness. The most potential application of graphene at present is to become a substitute for silicon, to manufacture ultra-miniature transistors, and to produce future supercomputers. Replace silicon with graphene, and computer processors could run hundreds of times faster. Plus, graphene is almost completely transparent, absorbing only 2.3 percent of light. On the other hand, it is so dense that even the smallest gas atoms (hydrogen atoms) cannot penetrate. These characteristics make it ideal as a raw material for transparent electronics, such as transparent touch displays, light-emitting panels and solar panels. As a new type of nanomaterial with the thinnest, highest strength, and strongest ele...
