Patent ID: 8891584

Claim:
A shaft high temperature continuous graphitizing furnace, comprising: a closed furnace body, a cooling area below the furnace body, a discharging outlet below the cooling area, a discharging device connected with the discharging outlet, a cooling system connected with the cooling area, a flue connected with the furnace body, and a desulfurizing device connected between the flue and the furnace body; wherein the furnace body comprises a shaft cylindrical structure, a feeding inlet at an upper end thereof, and an electrode pair; wherein the electrode pair comprises an upper electrode located at the top of the furnace body and a lower electrode located at the bottom of the furnace body, configured to form an umbrella or truncated cone shaped electric field having a lower cross section area greater than its upper cross section area between the upper electrode and the lower electrode that forms a high temperature area around the discharging outlet which ensures raw materials in the area can be heated during falling; and wherein the flue of the furnace body is in a circular four-hold shape, and the discharging device uses an automatic control system.
