摘要： Disclosed is a high-temperature flue gas recovery apparatus for a melting furnace, which relates to copper production, including a preheating chamber and a feeding mechanism, a lower end of the preheating chamber being in communication with a feeding port of the melting furnace, the feeding mechanism being disposed above the preheating chamber to deliver feedstock into the preheating chamber, a plurality of layers of buffer mechanisms layered in an upper-lower manner being provided in the preheating chamber, each layer of the buffer mechanism including a buffer element and a drive element, the drive element driving the corresponding buffer element to move such that the feedstock on the buffer element of an upper-layer buffer mechanism falls onto the buffer element of a lower-layer buffer mechanism, a gap allowing a gas to pass through being provided between the buffer mechanisms and an inner wall of the preheating chamber. The solution may recover the high-temperature flue gas produced by the melting furnace to preheat the feedstock, thereby enhancing the energy utilization ratio during the production process; moreover, with the plurality of buffer mechanisms, the solution may charge the feedstock into the melting furnace in small quantity per time and in multiple times, facilitating accurate control of the feeding rate and amount of the feedstock.
