PROBLEM TO BE SOLVED: To enable to remove iron powders stuck to a pipe for removing iron, exactly and without scattering, and to maintain iron-removing performance constant. SOLUTION: This device is provided with plural iron removing pipes 12 arranged zigzag on a frame 11, cylindrical bar magnets 13 respectively enabling to insert and pull out against respective iron removing pipes 12, a cylinder 15 for magnets which move respective bar magnets 13 so as to enable to insert and pull out them against the iron removing pipes 12 via a magnet holding plate 14 held with the one ends of the bar magnets 13 in one body, and iron- made iron removing rings 16 engaged outside the iron removing pipes 12 and reciprocally sliding on the outer peripheral surfaces of the iron removing pipes 12 in the shaft direction by a magnetic force of the bar magnets 13, in accordance with an inserting and pulling-out operations of the bar magnets 13 against the insides of the iron removing pipes 12. |
