Description

Technical Field

[0001] The utility model belongs to the technical field of anode furnaces, and in particular relates to a chute device and an anode furnace with the chute device. Background Art

[0002] In order to improve the use and processing performance of copper, it is necessary to remove impurities in crude copper, such as nickel, lead, arsenic, etc., and recover valuable metals such as gold and silver. This is the refining process of crude copper. The process is generally divided into two stages. One is to refine crude copper into anode copper by pyrometallurgy, and the other is to electrolytically refine anode copper into electrolytic copper. Pyrometallurgy refining of crude copper is generally carried out in an anode furnace. At present, the copper discharge equipment of the anode furnace is generally a combination of a movable chute and a fixed chute. The molten copper flows out of the copper outlet and directly falls into the movable chute, and then flows into the fixed chute from the movable chute. Because the height difference between the copper outlet of the furnace body and the movable chute is about 4m (in the early stage of copper discharge), the molten copper falls vertically into the movable chute and splashes severely. Each furnace casting process will cause a large amount of condensed copper to splash in and around the chute, the regional temperature is too high, and the equipment is damaged to varying degrees.
