Description

TECHNICAL FIELD

[0001] The utility model relates to the field of iron removal equipment, especially to a permanent magnet impurity removal equipment for aluminum ash. BACKGROUND

[0002] Aluminum ash is a typical hazardous solid waste produced in the process of aluminum electrolysis, processing and regeneration. It is mainly divided into electrolytic aluminum ash and aluminum alloy ash according to different sources. With the improvement of environmental protection consciousness and sustainable development concept, various technologies have emerged in the past few decades based on the importance of resource recycling and the requirement of environmental protection, mainly including the preparation of alumina, aluminum chloride water purifying agent, building materials and road materials, various refractory materials, etc.

[0003] Before the recycling of aluminum ash, it needs to be de-ironed to remove the magnetic material in the aluminum ash. The market generally uses electromagnet to magnetically attract and remove impurities. The existing technology (publication number: CN107115965B, publication date: 2019.03.12) discloses a silicon carbide powder de-ironing device and its use method, which uses a first screening device and a second screening device to remove magnetic material. The first screening device uses an electromagnet for magnetic attraction. After the electromagnet rotates, the magnetic material can be transported to the first collection box for recycling by powering off the electromagnet and the scraper. However, when the electromagnet is powered off, the entire magnet has no magnetic attraction effect. After a certain amount of material is input into the hopper, the input of the hopper needs to be stopped, which cannot achieve the effect of continuously inputting material for magnetic attraction and impurity removal, resulting in low efficiency. The existing permanent magnet scheme also has the problem of poor impurity removal effect. Since the permanent magnet has a longer service life than the electromagnet, it is necessary to design a permanent magnet impurity removal equipment for large quantities of aluminum ash. SUMMARY
