The graphitization furnace includes a heat preservation cylinder, both ends of the heat preservation cylinder are rotatably connected with end covers through bearings, the end covers are connected with legs, electric heating rods are fixed between the two end covers, internal thread blades are fixed in the heat preservation cylinder, a feed port is fixed at the top of one end cover, a discharge port is fixed at the bottom of the other end cover, an external gear is fixed outside the heat preservation cylinder, the external gear is meshed with the power gear, and the power gear is connected with the rotary power device. The technical structure is simple, easy to use, makes full use of the heat of the heater, and reduces the heat insulation requirements of the heat insulation shell.
A continuously producible high-temperature graphitization furnace, comprising an integral furnace lining, a furnace cover and an annular flue on the top. The integral furnace lining is integrally cast and includes a heat preservation layer, a medium temperature layer, a high temperature layer and a working layer. The heat preservation layer is wrapped on the outer wall of the medium temperature layer, and the medium temperature layer is wrapped on the outer wall of the high temperature layer and the outer wall of the working layer, the installation end of the furnace cover is fixedly installed on the top of the high temperature layer and the working layer, and is connected to the annular flue of the furnace roof through a pipeline. The pipeline is fixedly installed on the top of the insulation layer and the medium temperature layer. The annular flue and the furnace cover form a top insulation area; This technology realizes rapid heating, effectively reduces power consumption, reduces the volatilization of dust and smoke, and improves the working environment.
Packing for anode sealing of graphitization furnace. This technology uses the characteristics of clay, bentonite and ultrafine powder to ensure that the sealing filler is easy to apply. The filler is added with anti-oxidation components, such as silicon carbide, carbon black or graphite, which can preferentially react with air to ensure that the cathode of the electrode is not oxidized by air. In addition, the reaction characteristics of the filler kyanite, andalusite, time, MgO and other components at high temperatures ensure the high-temperature expansion performance of the filler and block the air channel, thereby prolonging the service life of the negative electrode. Therefore, the sealing packing can prolong the service life of the graphitizing furnace.
The structure and construction method of the combined graphite furnace head and furnace tail are characterized in that the top is provided with an open groove structure for installing the electrode and the carbon slider around it. It fundamentally solves the common technical problem of inconvenient installation and maintenance of the overall furnace head and furnace tail outer wall structure of the graphitization furnace, which is of great significance to reduce the labor intensity of workers and improve the installation and production efficiency.
The continuous graphitization furnace can reduce the influence of harmful gases on the graphitization of materials, improve product quality, and can continuously graphitize materials. The graphitization furnace flue gas desulfurization and dust removal process is separated from dust removal and desulfurization, combined with gravity dust removal, water washing dust removal and electric field dust removal, to fully remove the flue gas discharged from the graphitization furnace, to achieve a purification standard discharge, which greatly improves the dust removal effect and saves A large number of exhaust gas processors.
