Description

Technical Field

[0001] The utility model belongs to the technical field of phosphate ore smelting, and in particular relates to a large electric furnace with lifting electrodes. Background Art

[0002] The electric furnace method for producing yellow phosphorus involves adding a mixture of phosphate rock, silica, and coke to an electric furnace. Silica acts as a flux, and coke acts as a reducing agent and conductor. Electrode rods are introduced to convert electrical energy into heat, melting it to produce a chemical reduction reaction, which sublimates the phosphorus. The phosphorus-containing furnace gas is condensed, washed, refined, and separated to obtain the finished phosphorus. The phosphorus furnace is mainly composed of a furnace body, electrodes and an electrode lifting device, an electric furnace transformer, and monitoring and control instruments. Traditional electrode lifting circuits usually heat the furnace body by inserting electrode rods. However, electrode rods are consumables and require frequent replacement due to repeated wear and tear from the ore after heating. The traditional electrode rod replacement process is cumbersome, and when there are multiple electrode rods, each electrode rod needs to be disassembled and replaced with a new one, which is time-consuming and labor-intensive, and has low replacement efficiency.
