The invention relates to the technical field of accessory devices of electric furnaces, in particular to an energy-saving and environmentally-friendly electric furnace for preparing high-carbon ferrochrome. According to the energy-saving and environmentally-friendly electric furnace, heat in high-temperature exhaust gas generated by the electric furnace can be reutilized to reduce the waste of theheat and improve the protection of the work environment and practicability; added furnace materials can be preheated and dried to prevent surging caused by adding the low-temperature or damp furnacematerials into liquid metal to be mixed with slag, thereby avoiding scald accidents caused by splashing of the furnace materials and improving safety; and meanwhile cleaning of scum is facilitated sothat using reliability can be improved. The energy-saving and environmentally-friendly electric furnace comprises a furnace shell, a transformer, a furnace cover, a graphite electrode, a tap hole, a slag removal port, a base, a support seat, a roll air cylinder, a fixing frame, a charging box, a feeding motor, a feeding pipe, a heat conducting coil pipe, a first exhaust pipe, a support plate, a rotating shaft, a spiral conveying blade, a treatment tower, a negative pressure fan, an activated carbon adsorption device, a tubular heat exchanger, a communication air duct , a second exhaust pipe and a sealing device.
Description
technical field [0001] The invention relates to the technical field of electric furnace attachments, in particular to an energy-saving and environment-friendly electric furnace for preparing high-carbon ferrochrome. Background technique [0002] As we all know, the energy-saving and environment-friendly electric furnace for preparing high-carbon ferrochrome is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Electric furnaces can be divided into resistance furnaces, induction furnaces, electric arc furnaces, plasma furnaces, electron beam furnaces, etc. Compared with the fuel furnace, the advantages of the electric furnace are: the atmosphere in the furnace is easy to control; the material is heated quickly; the heating temperature is high; the temperature is easy to control; the production process is easier to realize mechanization and automation; And it is more environmentally friendly, which is conducive to alleviating th...
