[0002] Oxygen-enriched side-blowing smelting furnace is a high-tech environmentally friendly equipment, mainly used in the steel industry and non-ferrous metal industry. Its working principle is to continuously add solid raw materials such as rare earth alloys into the furnace, heat and melt them through oxygen side-blowing, and realize rapid oxidation-reduction reaction in the furnace while adding reducing agents, thereby ensuring the control of furnace temperature, melt composition and atmosphere. After drying, sludge, waste activated carbon, limestone, quartz stone, carbon concentrate and other materials are mixed and transported to the discharge port of the smelting furnace by a fixed conveyor belt.

[0003] The traditional fixed belt used for feeding materials in oxygen-enriched side-blown smelting furnaces has the following three disadvantages. First, when the discharge port of the smelting furnace is blocked, the fixed belt hinders the cleaning of the discharge port; second, when the smelting furnace is improperly controlled and flames rise, the belt will burn; third, when the furnace is shut down or dead or the ingredients are unqualified, the equipment conveying materials to the belt cannot be stopped. If the conveyor belt is stopped, it will cause material accumulation or overload and fall, and the material on the belt cannot be cleaned in time, affecting normal production. Utility Model Content
