Energy-saving efficient carbon pipe furnace

Abstract

The invention discloses an energy-saving efficient carbon pipe furnace which comprises an external structure and an internal structure. The external structure comprises a furnace head pipe, a large-current transformer, a first copper plate, a second copper plate, a top beam, a cover plate fastening screw, a cover plate, a top beam support, a heat preserving material inlet, an end cover, a furnace shell, a furnace body support, a furnace tail cooling water jacket water outlet, a furnace tail cooling water jacket, a furnace tail cooling water jacket water inlet and a cooling water jacket water inlet. The internal structure is arranged in the external structure. The internal structure comprises a fixing bolt, a copper electrode, a cooling water jacket, a graphite electrode sleeve, a first isolating steel sleeve, a second isolating steel sleeve, a furnace tail pipe, a transition flange, a cooling water jacket water outlet and a heating carbon pipe. Compared with the prior art, the energy-saving efficient carbon pipe furnace has the advantages that the structure is simple and exquisite, the function is complete, the purification efficiency is high, the graphite purification degree is high, a part is not prone to damage, the heat preserving effect is good, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of graphite purification, in particular to an energy-saving and high-efficiency carbon tube furnace. Background technique [0002] The existing graphite purification process is usually crushed after the graphite ore is mined, and then most of the impurities such as stones with high density are removed by flotation, and then the graphite with low purity is cleaned with acid. Usually, the purity of acid-washed graphite can reach more than 95%, but compared with the graphite purity required by graphite electrodes and artificial diamond industries, it is far from enough, so high-temperature purification graphite equipment is required in the subsequent process. [0003] At this stage, there are three kinds of graphite purification equipment commonly used in industry. According to the output of a single equipment from large to small, they are Acheson furnace, large graphite purification furnace and carbon tube furnace. [...
