It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0039] The present application provides a separation device for magnetic materials, including a bracket, a rotating magnetic drum, a driving mechanism, a scraping structure and a collecting structure. Powder is placed in the cavity of the rotating magnetic drum, and the rotating magnetic drum is driven to rotate by the driving mechanism. The magnetic material in the powder is adsorbed to the magnetic area, and the magnetic material adsorbed by the rotating magnetic drum in the magnetic area is scraped off by the scraping part, and the magnetic material is collected by the collecting structure. In this way, the magnetic material in the powder can be screened and collected in the rotating magnetic drum, which effectively reduces dust in the magnetic separation process and is conducive to improving the working environment.

[0040] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0042] In this embodiment, the powder is placed in the cavity of the rotating magnetic cylinder 2, and the rotating magnetic cylinder 2 is driven to rotate by the driving mechanism 3. The magnetic material in the powder is adsorbed to the magnetic area to realize the screening of the magnetic material in the powder; when the driving mechanism 3 drives the rotating magnetic cylinder 2 to rotate, the scraper part 42 is stationary relative to the rotating magnetic cylinder 2, and the scraper part 42 can scrape off the magnetic material adsorbed by the rotating magnetic cylinder 2 in the magnetic area, and collect the magnetic material through the collecting structure 5, thereby realizing the screening and collection of the magnetic material in the powder in the rotating magnetic cylinder 2, effectively reducing the dust in the magnetic separation process, and helping to improve the working environment.

Among them, the motor drive mode can be adopted, the output shaft of the motor is connected to the rotating shaft 32, and the rotating shaft 32 is driven to rotate by the motor; the manual drive mode can also be adopted, and the rotating shaft 32 is rotated by the operator. At this time, in order to facilitate operation, a rocker 34 can be connected to the rotating shaft 32, and the rotating shaft 32 is driven to rotate by rotating the rocker 34.

[0055] In order to improve the stability of the rotation process, two fixing blocks 31 can be set, and the two ends of the rotating shaft 32 are respectively set on the two fixing blocks 31, and the gear 33 is set between the two fixing blocks 31. In this way, the gear 33 can be better supported.
