This utility model discloses a
positive pressure smelting industrial electric furnace, relating to the field of
smelting equipment technology. The utility model includes a furnace body and a furnace cover. A
flue gas treatment component is provided on one side of the top of the furnace cover, and a feeding component is provided on the other side of the top of the furnace cover. The
flue gas treatment component includes a
combustion cylinder located on one side above the furnace cover. An overflow
pipe is fixedly connected to the bottom of the
combustion cylinder, and the bottom end of the overflow
pipe extends to the upper inner side of the furnace body. This utility model introduces
carbon monoxide from the furnace body into the
combustion cylinder for combustion through the overflow
pipe on the combustion cylinder. The heat generated by the combustion is used to heat the water in the sleeve through heat exchange fins, solving the problem of difficulty in recovering and reusing the
waste heat generated by
carbon monoxide combustion in existing systems. Simultaneously, the
threaded rod in the mounting frame drives the collar and the feeding pipe to rise and fall, ensuring that the
discharge end of the feeding pipe is always above the
molten pool inside the furnace body, solving the problem of difficulty in preventing some
powder from clogging the furnace
flue during the feeding process.
