A multi-stage grinding and stirring device for graphene slurry

Abstract

The invention discloses a graphene slurry multistage grinding and stirring device which comprises a reaction kettle body. Sealing covers are mounted at the upper end and the lower end of the reaction kettle body; a motor frame is arranged at the upper end of the corresponding sealing cover; a driving motor is arranged in the motor frame; a driving main shaft is connected to the lower end of the driving motor; and a hopper-type feeding device is arranged at the upper end of the sealing cover. Three grinding and stirring mechanisms are mounted on the driving main shaft through a fixing clamping block; multistage screening plates are arranged between the grinding and stirring mechanisms; a discharging port is formed in the lower end of the reaction kettle body; a conical grinding mechanism is arranged at the right end of the discharging port; and the conical grinding mechanism is mounted at the lower end of the driving main shaft. When stirring blades rotate, grinding rods make contact with graphene slurry firstly, after the graphite slurry collides grinding particles of grinding sections, hard particles inside the slurry are well crushed and collided, thus internal slurry grinding is achieved, graphene slurry stirring and grinding integration is achieved, multistage processing is well conducted, the finer effect is achieved, and the graphene slurry multistage grinding and stirring device is worth popularizing.

technical field [0001] The invention relates to the technical field of grinding and stirring, in particular to a graphene slurry multistage grinding and stirring device. Background technique [0002] Graphene is a carbon atom with sp 2 The honeycomb planar film formed by hybridization is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called single atomic layer graphite. The common powder production methods of graphene are mechanical exfoliation method, redox method, and SiC epitaxial growth method, and the film production method is chemical vapor deposition (CVD). Due to its very good strength, flexibility, electrical conductivity, thermal conductivity, and optical properties, it has made great progress in the fields of physics, materials science, electronic information, computers, aerospace and other fields. One of the most important properties of graphene is its unique Carrier properties and massless Dirac fermion properties. [000...

Problems solved by technology

[0005] However, after the initial production of the graphene slurry, it needs to be well ground and stirred. However, during the stirring process, it is easy to cause the material to follow the rotation of the stirring device, resulting in uneven stirring of the graphene slurry. It is usually separated from the stirring process, which increases the difficulty of operation. If the material is directly ground to a certain size during grinding, the grinding efficiency of graphene slurry will be low. Therefore, a graphene slurry is designed.
