Description

Technical Field

[0001] The invention relates to the technical field of waste slag recovery, and in particular to a waste slag recovery device for copper smelting. Background Art

[0002] Copper smelting is still dominated by pyrometallurgy, and its output accounts for about 85% of the world's total copper output. Pyrometallurgy generally involves first increasing the copper content of raw ore with a few percent or thousandths of copper to 20-30% through mineral processing, and then smelting it in a closed blast furnace, reverberatory furnace, electric furnace or flash furnace as copper concentrate. The resulting matte is then sent to a converter for blowing into crude copper, and then oxidized, refined and impurity-removed in another reverberatory furnace, or cast into anode plates for electrolysis to obtain electrolytic copper with a grade of up to 99.9%.

[0003] A lot of waste slag will be generated during the copper smelting process. In order to save costs and protect the environment, the waste slag needs to be recycled. The device for recycling waste slag is particularly important. The copper slag itself may be accompanied by a relatively high temperature, and the smelting furnace is at different heights, so it is not very convenient to recycle. Those skilled in the art have conducted research and improvements on this, such as a waste slag recovery device for copper smelting with application number CN202020915709.5. This technical solution drives the chain up and down through the forward and reverse rotation of the motor to adjust the height of the box, which is convenient for recycling waste slag at different heights. However, this technical solution cannot cool the waste slag that has just been discharged, which is not conducive to subsequent collection and processing.
