Metal nano material preparation device and method

Abstract

The invention discloses a metal nano material preparation device and method. The device comprises a stirring box for pretreating processing raw materials, the discharge end of the stirring box is connected with a drying box for quickly drying a solid-liquid mixture through a discharge pipe; the discharging end of the right side of the drying box is connected with a cyclone separator used for separating materials in the solid-liquid mixture through a communicating pipe, a collecting box used for collecting solid materials is arranged at a discharging opening in the lower end of the cyclone separator, and an exhaust pipe is arranged at the upper end of the cyclone separator; a feeding end and a water adding end are arranged at the upper end of the stirring box. The stirring device is designed for overcoming the defects of an existing device, the stirring effect is greatly improved, lump-shaped materials deposited in the stirring device can be crushed in time, collision of fluid can be promoted while crushing is conducted, the mixing effect is good, the preliminary treatment effect on the materials is guaranteed, later machining is guaranteed, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of nanomaterial processing equipment, in particular to a metal nanomaterial preparation device and method. Background technique [0002] Metal nanomaterials refer to polycrystalline metal materials whose grain size is on the order of nanometers (usually less than 100nm). Its crystal grains are fine and its grain boundary volume fraction is very large, so it exhibits many performance characteristics that ordinary metal materials do not have. The high strength of nanomaterials stems from the obstruction of dislocation movement by a large number of grain boundaries. This strengthening method is different from the traditional alloy strengthening and deformation strength, and is an extreme state of grain refinement strengthening; the application research of nanotechnology is developing at a high speed in the four major fields of semiconductor chips, cancer diagnosis, optical new materials and biomolecular tracki...

Problems solved by technology

[0003] The existing metal nanomaterials preparation device has many processes in the production process, and it is easy to stir very unevenly, so that the particle size of the prepared nanomaterials is uneven, and the use is limited. The existing patent announcement number CN206351252U patent announcement A preparation device for metal nanomaterials is developed. The device stirs the material and water by setting a stirring plate. This stirring method itself cannot remove impurities with unqualified volume in the material, and it is also inconvenient to process the agglomerated material. Stirring problem
