The upper end of the slag discharge cover plate 207 is hinged to the outer surface of the lifting furnace cover 2, and the waste slag storage box 3 is located below the outer end of the slag discharge port 206; under normal circumstances, the slag discharge cover plate 207 covers the outside of the slag discharge port 206 to seal the slag discharge port 206 and reduce the loss of heat inside the smelting furnace. When the slag discharge push bucket 9 moves to the right, the slag discharge cover plate 207 is pushed outward by the slag discharge push bucket 9 to rotate it outward, thereby opening the slag discharge port 206 to discharge the slag of the molten metal.

The dividing shaft 1003 and the dividing and selecting plate 1004 are controlled to rotate by the dividing drive 11, so that the material is transferred to the dividing port 1002 and connected thereto, and the material is fed through the dividing port 1002 and the feed port 208. This feeding method can realize the non-opening feeding of the smelting furnace, avoid the loss of heat energy during the feeding process, and avoid the blockage caused by the metal melt agglomeration caused by excessive feeding at a single time.

[0024] The working principle of this embodiment: First, during the metal smelting process of the smelting furnace, the lifting furnace cover 2 is lifted by the lifting device and covers the upper opening of the smelting furnace body 1. When adding materials, an appropriate amount of metal materials is put into the feeding hopper 1001, and the energy-saving feeder 10 is isolated by the material selection plate 1004 inside the energy-saving feeder 10.

The scraping of the inner wall of the slag hopper 7 collects and pushes the slag inside the slag hopper 7, and the waste slag in the slag hopper 7 is pushed to the right by the slag discharge pushing bucket 9. As the slag discharge pushing bucket 9 moves to the right, the slag discharge cover 207 is pushed to the right, so that the slag discharge cover 207 is rotated by the thrust, and the slag discharge port 206 is opened, so that the slag discharge pushing bucket 9 pushes the slag through the slag discharge port 206 and pushes it into the waste slag storage box 3 for collection. There is no need to manually open the cover to clean the slag, which reduces the heat loss during the opening of the smelting furnace.
