The invention relates to an electric furnace electrode sealing device, and belongs to the field of electrode configuration. A base is internally provided with an insulating and heat-resistant electrode hole brick and is fixed to a furnace cover through insulation connection. An A type pressing block, a B type pressing block, an inner sealing ring and an outer sealing ring in a sealing cylinder arecombined to form a labyrinth sealing device. The inner side flexible sealing ring is in direct contact with a graphite electrode and is responsible for the dynamic sealing of the graphite electrode.The sealing cylinder is fixed to the base by a clamping buckle, and the problem that the graphite electrode and a lower base electrode hole are not easy to center when installed can be solved; and anelastic compression device can adjust the pressure of an inner pressure block of the sealing cylinder on the flexible inner and outer sealing ring, then the tightness degree of contacting of the sealing rings and the electrode is adjusted to achieve the effect of regulating the seal. The electrode sealing device has compact structure, convenient adjustment and maintenance, the problem of dynamic sealing of the electric furnace electrode in solid waste resource at high temperature and charged is solved, and closed smelting in a furnace is realized.
Description
technical field [0001] The invention belongs to the field of electrode configuration, and in particular relates to an electrode sealing device for an electric furnace for recycling solid waste. Background technique [0002] Traditional metallurgical electric furnaces do not have high requirements on the sealing of electrode holes. For example, steelmaking electric arc furnaces and ladle refining furnaces are equipped with small refractory covers at the electrode holes of the furnace cover to insulate and isolate the electrodes. Heat and anti-splash effect, in order to prevent the electrode from moving and colliding with the small furnace cover of the refractory material, there will be a large gap at the electrode hole. [0003] The traditional ferroalloy submerged thermal electric furnace is large in size. When the electrode diameter is graphite electrode, the diameter is generally above Φ700mm. When using self-baking electrode, the diameter can reach Φ2000mm, so the shape o...
