Nanometer material preparation device for material automatic grading

Abstract

The invention discloses a nanometer material preparation device for material automatic grading. The nanometer material preparation device comprises a feeding unit, a crushing unit, a grading unit, a discharging unit and a controlling unit. The controlling unit is electrically connected with the feeding unit, the crushing unit, the grading unit and the discharging unit. The feeding unit is used forreceiving first materials added externally. The crushing unit is used for crushing the first materials to obtain second materials. The grading unit is used for detecting the diameters of the second materials. If the diameters of the second materials are less than or equal to the preset value, the second materials are used as intended materials. The discharging unit is used for discharging the intended materials. The feeding unit is used for adding the materials, the crushing unit crushes the materials, the grading unit judges material grades and distributes the materials, the discharging unitdischarges the materials meeting the production requirements, so that the diameters of the discharged nanometer material is within a certain range, the problem that the nanometer material particles are uneven is solved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a nanomaterial preparation device for automatically grading materials. Background technique [0002] There are many methods for preparing nanoparticles, mainly including: vacuum condensation method, using vacuum evaporation, heating, high-frequency induction and other methods to vaporize raw materials or form equal particle bodies, and then quench. It is characterized by high purity, good crystal structure, and controllable particle size, but requires high technical equipment. The physical pulverization method is to obtain nanoparticles by mechanical pulverization, electric spark explosion and other methods. It is characterized by simple operation and low cost, but the product has low purity and uneven particle distribution. The mechanical ball milling method uses the ball milling method to control appropriate conditions to obtain nanoparticles of pure elements, alloys or...
