Abstract

The invention discloses a graphite expansion furnace used for preparing graphite paper, and belongs to the technical field of graphite paper production equipment. The graphite expansion furnace comprises a pedestal. The pedestal is provided with a horizontally arranged furnace body. One end of the furnace body is provided with a material inlet, and the other end of the furnace body is provided with a material outlet. The furnace body is provided with a graphite circulating pipeline made of a metal material. Two ends of the graphite circulating pipeline are respectively connected to the material inlet and the material outlet. The external surface of the graphite circulating pipeline is covered with a thermal insulation layer. The periphery of the thermal insulation layer is provided with inductance elements. According to the graphite expansion furnace, no fuel burns in a process of heating the graphite circulating pipeline and the process produces no gas containing chemical components, thereby effectively controlling the sulphur content in graphite worms, reducing greatly the sulphur content in the graphite paper, and improving the rate of finished products of the graphite paper. The thermal insulation layer is designed, and therefore the inductance elements generate no heat, the thermal conversion efficiency is high, energy consumption is low and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of graphite paper production equipment, and in particular relates to a graphite expansion furnace for preparing graphite paper. Background technique [0002] Graphite paper is widely used in the dynamic and static sealing of machines, pipes, pumps, and valves in industries such as electric power, petroleum, chemical industry, instrumentation, and machinery. It is an ideal new sealing material to replace traditional seals such as rubber, fluoroplastics, and asbestos. [0003] During the preparation process of graphite paper, high-carbon graphite flakes need to be expanded. At present, the existing graphite expansion furnaces in China use liquefied petroleum gas or diesel as fuel to heat the graphite expansion furnace cavity to about 900°C, and then use wind force to feed the expandable graphite raw materials. The expandable graphite flakes at high temperatures The acid radical ions between them will be viole...
