Feeding method and equipment of anode refining furnace

Abstract

The invention discloses a feeding method and the feeding equipment of an anode refining furnace. Feeding is realized in a way that: through a connecting chute between a converting furnace and the anode refining furnace, hot crude copper produced by the converting furnace automatically flows into a feed inlet on the upper part of a headwall of the anode refining furnace due to an altitude difference between the converting furnace and the anode refining furnace, and then enters the anode refining furnace for refining. In the equipment, the feed inlet is fixedly arranged on the upper part of the headwall of the anode refining furnace by a bracket, aslant rotates with the anode refining furnace, forms the altitude difference of at least 1 cm with a copper placement opening of the converting furnace, and is jointed with the connecting chute. As the feed inlet and a smoke outlet are arranged on the two headwalls of the anode refining furnace respectively, the method has the advantages of low cost, small discharged smoke amount, high temperature and the favorability for waste heat recovery and treatment. The equipment has the characteristics of simple structure, low cost, secure operation, the capacity of avoiding the high-altitude lifting and delivery of high-temperature melt, high furnace sealing property, less air leakage, the favorability for flue gas waste heat recovery and subsequent flue gas treatment, and particular application to copper smelting plants adopting a copper continuous converting process.

Description

Technical field [0001] The present invention relates to an anode refining furnace, and in particular to a charging method and equipment for an anode refining furnace. Background technique [0002] The feeding ports of existing anode refining furnaces are all located at the top of the furnace body. A copper smelting plant that needs to use continuous feeding for anode refining, if the feeding port is set at the top of the furnace body, and the flue gas is discharged from the feeding port while feeding, a complex and expensive smoke collecting hood needs to be installed above it, and the feeding port and collector The gaps in the hood will suck in a large amount of cold air, resulting in a large amount of exhaust gas. At the same time, the smoke components will be diluted and the temperature of the smoke will be lowered, which is not conducive to the recovery of waste heat from the flue gas and the treatment of the flue gas. Contents of the invention [0003] A technical pr...

Problems solved by technology

Copper smelters that need to use continuous feeding for anode refining, if the feeding port is set at the top of the furnace body, and the flue gas is discharged from the feeding port at the same time as feeding, a fume collecting hood with complex structure and high cost needs to be installed above, and the feeding port and collecting A large amount of cold air will be inhaled through the gaps in the hood, resulting in a large amount of exhausted smoke, while diluting the components of the smoke and reducing the temperature of the smoke, which is not conducive to the recovery of waste heat from the smoke and the treatment of the smoke
