Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting auxiliary devices, in particular to an iron chip removing device for producing high-quality aluminum alloy using recycled aluminum. Background Art

[0002] When recycling and processing recycled aluminum through a double-chamber furnace, aluminum waste of different specifications will be added to the two feed ports. Large aluminum ingots / tubes and other casting structures that are discarded due to production quality not meeting the requirements are generally put into the furnace through the feed port on the front side of the furnace door, while aluminum waste recycled from life by other means is required to be crushed into smaller pieces and then added through another feed port. The inventor noticed that most of these small pieces of waste contain some iron products. Although the iron slag can be removed by other means after the aluminum in the furnace is melted, if the iron filings can be screened once before the aluminum waste is put into the furnace, it can provide better protection and purification for the entire recycled aluminum process; this is the technical problem that needs to be solved at present.
