1. A high-temperature flue gas recovery apparatus for a melting furnace, comprising: 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 comprising 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 for a gas to pass through being provided between the buffer mechanisms and an inner wall of the preheating chamber,
wherein the feeding mechanism comprises a flue-gas collection hood, a transverse movement assembly, and a pusher assembly disposed above the transverse movement assembly, a lower end of the flue-gas collection hood being in communication with the preheating chamber, an exhaust pipe being provided on the flue-gas collection hood, the transverse movement assembly being transversely movable relative to the flue-gas collection hood, one end of the transverse movement assembly extending into the flue-gas collection hood, the pusher assembly comprising a lift drive and a lift plate, the lift drive being mounted on the preheating chamber, and the lift drive driving the lift plate to lift.
