Efficient Sealed Continuous Graphitization Furnace

Abstract

The invention relates to an efficient sealing continuous graphitization furnace, comprising a furnace body, wherein a sealing cover is arranged above the furnace body, and is provided with a feeding hopper and a volatile matter discharge device; the furnace body is internally provided with a graphite heating chamber, the graphite heating chamber is divided into a pre-heating roasting area, a slow heating area and a free heating area from top to bottom along the axial direction, the center of the graphite heating chamber is provided with an anode electrode, a cathode electrode is arranged at the outer ring of the anode electrode, and graphite to be heated is arranged between an anode and a cathode; the bottom end of the graphite heating chamber is communicated with an inlet end of a sealing rotary cooler through a dump valve, and a discharge end of the sealing rotary cooler is connected with a load weighing device. The efficient sealing continuous graphitization furnace provided by the invention has the advantages that the quality is stable, the technical indexes such as the graphitization quality, the graphite purity and the specific surface area can be easily ensured, the energy consumption is low, a volatile matter can be effectively discharged, and the aims of being efficient and environment-friendly are realized.

Description

technical field [0001] The invention relates to a graphitization furnace, in particular to a high-efficiency sealed continuous graphitization furnace. Background technique [0002] High-purity graphite is widely used in battery anode materials, nuclear graphite in the nuclear industry, military high-temperature-resistant graphite and stealth materials, anti-corrosion materials, conductive materials, metallurgical industry, petrochemical industry, etc. It is a very important industrial material. [0003] At present, the main equipment used to produce graphitized powder at home and abroad includes Aqisun graphitization furnace, serial graphitization furnace and electrode heating graphitization furnace. Both the Acheson furnace and the series furnace use resistance heat transfer to heat graphite, the heating efficiency is low (the effective utilization rate of power is about 30%), the graphite heated in the furnace is uneven, the heating temperature of graphite is low, and the ...
