Description

Technical Field

[0001] The present invention relates to the technical field of smelting furnaces, and particularly to an aluminum alloy smelting furnace with a conditioning and filtering function. Background Art

[0002] During the aluminum alloy smelting process, the metal loss that cannot be recycled due to aluminum oxidation and the interaction between aluminum and the furnace wall and refining agent is called burning loss. The total of burning loss and the metal contained in the slag is called melting loss. When using an aluminum alloy smelting furnace for smelting, due to different furnace charges, the slag amount is 2% - 5% of the furnace charge amount, and the aluminum content in the slag is about 40 - 60% of the slag amount. Therefore, correctly treating aluminum furnace slag and recovering the aluminum in the slag to reduce melting loss is of great significance.

[0003] The Chinese invention patent "CN114812170A" discloses an aluminum alloy smelting furnace with a conditioning and filtering function. In the present invention, a clamping rod is driven by a connecting rod to clamp the aluminum alloy smelting residue located at the top of the furnace body. At the same time, the residue in the furnace body is placed into the discharge chute, and then the residue in the discharge chute is rolled into the waste residue box by rotating a handwheel. Compared with manual slag scraping by workers with a slag bar, some residue dust is raised and exposed to the air, affecting the physical health of workers. At the same time, the scattered waste residue needs to be cleaned up twice later, which is time-consuming and laborious.

[0004] During the use of the above technical solution, although the clamping rod can be used to clamp the residue, since the position of the residue floating on the liquid surface is not fixed, the clamping rod needs to be accurately positioned each time it clamps, and it is difficult to ensure the stability after clamping the residue, so that the clamping rod is easy to break away after clamping the residue, and it is also difficult to clamp some smaller residues, thus affecting the filtering effect of the residue. Therefore, we propose an aluminum alloy smelting furnace with a conditioning and filtering function. Summary of the Invention
