Description

Production equipment and preparation method of graphite with refined structure
Technical Field
The invention relates to a production device and a preparation method of graphite with a refined structure.
Background
China is a big country for producing artificial diamonds, the development speed is extremely high, and the yield is continuous and the world is the first for many years. In the domestic huge artificial diamond tool and product industry, the hot-pressing sintering process of the diamond drill bit and the saw blade bit adopts graphite as a mould. This is because the carbon-graphite product has a series of excellent characteristics such that its melting point is high, and its mechanical strength does not decrease but increases at high temperatures. The average grain diameter of the graphite is 45-55 mu m, so that the graphite has an insufficiently compact microstructure, larger pores, lower machinable finish, low oxidation resistance and shorter service life, and is generally 4-6 times.
The ultrafine powder refers to micro solid particles with the size between molecules, atoms and bulk materials, generally refers to the range of 1-100 μm, and comprises various material particles such as metal, nonmetal, organic, inorganic, biological and the like. Ultrafine powders are generally classified into micron-sized, submicron-sized and nano-sized powders. The powder with the grain diameter larger than l mu m is called micron material, the powder with the grain diameter smaller than l mu m and larger than O.1 mu m is called submicron material, and the powder with the grain diameter between 0.001 and O.1 mu m (i.e. l to 100 mu m) is called nano material. The material is ultra-refined, especially in the submicron and nanometer state, and its dimensions are between those of atoms, molecules and bulk materials, so it is called the fourth state of matter. Along with the ultra-fining of the substance, the surface molecular arrangement, the electronic distribution structure and the crystal structure of the substance are changed, and the peculiar surface effect, small-size effect, quantum effect and macroscopic quantum tunnel effect which are not possessed by the block material are generated, so that the ultra-fine powder has a series of excellent physical, chemical and surface and interface properties compared with the conventional block material, and can obtain the extraordinary effect when in use. The graphite has strong greasiness and toughness, and the superfine graphite powder is widely applied to various fields due to the unique performance of the superfine graphite powder. How to obtain the superfine graphite powder is always a hot point and a difficulty of graphite deep processing.
The raw materials of the superfine graphite are natural crystalline flake graphite and artificial graphite. Flake graphite: the graphite in scaly and thin-leaf crystalloid is generally (1.2.0) × (0.1.0) mm in size, 4-5 mm in maximum and 0.02-0.05 mm in slice thickness, is mostly distributed in dip-dyed and flaxen shapes in rocks and has obvious directional arrangement; microcrystalline graphite: the diameter of the crystal is generally less than 1 micron, the crystal is an aggregate of microcrystalline graphite, and the crystal form can be seen only under an electron microscope; artificial graphite: anthracite, coke or petroleum coke is used as raw material, after being crushed, coal tar and pitch are added for kneading, after being extruded or compression molded, the mixture is roasted in an electric furnace in a mode of isolating air. The amorphous carbon material is obtained by roasting at 800-1300 ℃ for about 200-250 h. If the carbon is crystallized by roasting at 2400-2800 ℃ for 60-70 h to obtain the artificial graphite, the ultrafine powder has a large specific surface area and high surface energy and the particles are in an extremely unstable state, so that the ultrafine powder is attracted to each other and has a stable tendency, and the tendency causes the particles to agglomerate to influence the application effect of the artificial graphite. The ultrafine powder with poor dispersibility completely loses the original superiority in actual use, and the using effect is opposite, so that the dispersing technology of the ultrafine powder is the most key technology in the ultrafine powder technology in a certain sense.
The pretreatment of graphite powder comprises the processes of flotation, dehydration, drying and the like, but the prior art has low graphite crushing efficiency and cannot realize energy-saving utilization.
