High-purity graphite purification system

Abstract

The invention relates to a high-purity graphite purification system, the high-purity graphite purification system comprises a purification furnace, the purification furnace is in a vertically arranged cylindrical shape, the purification furnace comprises a furnace body, an air guide ring, an air inlet ring and a heating column, the furnace body is a cylindrical shell, the upper end and the lower end of the furnace body are respectively provided with an air outlet and a discharge port, the upper part of the furnace body is provided with a feed port, and the upper part of the furnace body is provided with a discharge port; the air guide ring and the air inlet ring are correspondingly arranged on the inner side and the outer side of the circumference of the furnace body respectively, the lower end of the air guide ring is fixedly connected with the furnace body in a sealed mode, a gap is reserved between the upper end of the air guide ring and the inner wall of the circumference of the furnace body, and an opening of the section of the air inlet ring is fixedly connected with the outer side of the circumference of the furnace body in a sealed mode. The air inlet ring communicates with the air outlet end of an inert gas source, and the heating column is coaxially and fixedly arranged in the furnace body. The invention aims to solve or at least alleviate the problems of high energy consumption and non-uniform heating during purification of the existing graphite high-temperature purification equipment, and provides the high-purity graphite purification system.

Description

technical field [0001] The invention relates to the technical field of graphite purification, in particular to a high-purity graphite purification system. Background technique [0002] Graphite is an important non-metallic mineral resource. It has high temperature resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, self-lubricating, thermal conductivity, and electrical conductivity. It is widely used in metallurgy, machinery, electronics, chemical industry, and light industry. , military industry, national defense, aerospace and refractory industries. [0003] In particular, special industries such as national defense and aerospace have very high requirements on the quality of graphite, and the finished graphite products obtained by conventional purification methods cannot meet the demand. At present, most of the graphite raw ore is firstly purified by flotation method, and then purified again by alkali-acid method. At this time, the c...
