Description

Technical Field

[0001] The utility model relates to the technical field of iron removal equipment, in particular to an iron removal device. Background Art

[0002] Iron removers are divided into flat plate magnetic separators, flat plate iron removers, drum iron removers and other equipment. It is a device that can generate a strong magnetic field attraction. It can remove ferromagnetic impurities mixed in the material to ensure the safe and normal operation of mechanical equipment such as crushers and grinders in the conveying system. At the same time, it can effectively prevent accidents caused by large and long iron pieces scratching the conveyor belt, and can also significantly improve the quality of raw materials. According to its iron unloading method, it can be divided into manual unloading, automatic unloading and program-controlled unloading. Due to different usage occasions and magnetic circuit structures, various series of products have been formed.

[0003] The existing drum type iron remover is mainly used to remove iron from powder and crushed residual anode. Although a large number of iron removers have been used and iron has been removed from materials of various particle sizes, the iron removal effect is not good. For example, when used for anode carbon iron removal in a carbon plant, the iron content of the anode after treatment is still as high as 550ppm or more, which is far from the target of 450ppm.

[0022] On the secondary conveyor belt, after being scraped and limited by the dust suppression hood Ⅱ, the iron chips are transmitted to the secondary active roller through the secondary conveyor belt.

The results show that the iron content of the fine residual material before iron removal is 4700ppm, and the iron content of the fine residual material after iron removal by the two-stage belt iron remover is reduced to 970ppm. The iron removal effect is obvious and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
