High-temperature furnace capable of continuously producing artificial graphite

Abstract

The invention discloses a high-temperature furnace capable of continuously producing artificial graphite. The furnace comprises a furnace lining, a working layer of the furnace lining is sequentiallyprovided with a water-cooled jacket, a low-temperature light heat preservation layer, a medium-temperature layer and a high-temperature layer from outside to inside, the upper portion of the furnace lining is provided with a furnace cover matched with the furnace lining, the furnace cover is provided with a smoke outlet, a graphite electrode positive electrode and a furnace top discharging hole, and the inner wall of the high-temperature layer is provided with a graphite electrode negative electrode; characteristics of a high-temperature fluidized bed are used for reference; the production mode of the traditional graphitization furnace is changed; a masonry or pouring process of a multi-layer structure is adopted; the water-cooled jacket is adopted by the outer layer, so that the operationenvironment is improved; inert gas can be introduced through a first distribution valve and a second distribution valve installed at the bottom of the graphite electrode negative electrode, the temperature of the discharged material is reduced, meanwhile, the temperature of the inert gas entering the furnace is increased, it is guaranteed that energy consumption is not greatly increased, the discharged material is cooled again through a heat energy recovery device, and the requirement for the proper temperature is met.

Description

technical field [0001] The invention relates to a high-temperature furnace, in particular to a high-temperature furnace capable of continuously producing artificial graphite. Background technique [0002] The current graphitization furnace basically adopts the structure of feeding from the upper part and discharging from the bottom, and calcining and graphitizing in the high temperature zone in the middle. A graphite electrode positive pole is installed on the top of the furnace, and the negative pole of the furnace is installed in the bottom area of ​​the furnace side. [0003] The advantage of this kind of kiln is that the construction difficulty is low, and the disadvantage is that the insulation effect of the furnace lining is relatively poor. The graphite electrode of the furnace core is often aggravated by side oxidation and electric sparks, and the temperature uniformity of the furnace core is not ideal, so production often occurs. The product quality fluctuates grea...
