PURPOSE:To surely convey out attracted matters in a liquid through a simple mechanism, by providing a comb-structured scraper which extends from a plate and by constructing a main body in the manner that it gradually extends away from a horizontal rotary shaft in the rotating direction of magnetizable discs. CONSTITUTION:A liquid such as waste water supplied from an inlet port 7 comes into contact rotating magnetizable discs 4 so that magnetic substances such as iron contained in the liquid are attracted on the side and peripheral surfaces of the discs. The attracted substances 10 are moved with the rotation of the discs 4. The substances attracted on the side surfaces are once peeled off when the substances reach comb members 92. The peeled substances are thereafter attracted again on the rotating magnetizable discs 4. Such peeling-off and attraction are repeated so that the substances are moved on the comb members 92 to the peripheral parts of the discs 4 and then conducted to fixed plates 93. The substances covey on the comb members are conjoined to those substances peeled off by the roots 92 of the comb members and located n the peripheral parts of the magnetizable discs. The conjoined substance are conveyed on the fixed plates and picked out from a removing section 94. |
