Vertical continuous induction type high-temperature graphitization furnace

The invention discloses a vertical continuous induction type high-temperature graphitization furnace. The graphitization furnace comprises a furnace body shell, a hopper positioned above the furnace body shell, and a discharging pipe positioned at the bottom of the furnace body shell, wherein the hearth inside the furnace body shell is divided into four areas from top to bottom, namely a preheating area, a heating area, a temperature reducing area and a cooling area; every two adjacent areas are communicated with each other or isolated from each other by a corresponding isolating material part having an opening and closing function; a discharging port of the hopper is connected with a feeding hole of the preheating area by a valve; a heat insulating layer is arranged in the peripheral direction of the outer wall of the hearth; a heater is arranged between the inner wall of the shell and the heat insulating layer segment outside the heating area; a cooling system is arranged outside the discharging pipe so that the cooling area is formed inside the discharging pipe. The graphitization furnace disclosed by the invention has the advantages of greatly increasing the yield and quality of a graphitized material, satisfying the technological requirements of thermal treatment of a cathode material of a power battery and improving the quality of the battery.
