[0048] Preferably, the main shaft 20 is connected with the annular magnet 30 through a plurality of supporting rods, and the two ends of the scraper 40 are located on the inner and outer sides of the annular magnet 30.

[0049] In the working process, the recycled aluminum melt is first introduced into the flow guide groove 10, and then the main shaft 20 drives the annular magnet 30 to rotate under the driving of the motor. Since a part of the annular magnet 30 is located in the flow guide groove 10, the annular magnet 30 can continuously contact the recycled aluminum melt in the flow guide groove 10, so as to suck away the iron slag mixed in the recycled aluminum melt through magnetic force, and then the iron slag adsorbed on the surface of the annular magnet 30 is scraped away through the scraper 40 arranged on the two sides of the annular magnet 30.
