Abstract
Description
磁性体が混じった液体を通す液体通路と、
前記液体通路中で一部が液面上方に露出するように配置され、回転することで、外周面に吸着された磁性体を搬送する回転ドラムと、
前記回転ドラムの内方に配置された磁石と、
を備え、
前記回転ドラムと液面とが交差する交差位置から液面より高い方の磁力よりも、前記交差位置から液面よりも低い方の磁力の方が大きい構成とした。
続いて、ドラム型分離装置1の動作について説明する。ドラム型分離装置1においては、回転ドラム20が回転駆動された状態で、クーラント液が液体通路10に流される。クーラント液が回転ドラム20と流路枠15との間を通過すると、クーラント液に含まれる磁性体kが磁石30(永久磁石33)に引き付けられて回転ドラム20の外周面に吸着される。角度範囲W3に配置された永久磁石33は強い磁力を発生させるため、クーラント液の流れに逆らって磁性体kを回転ドラム20へ吸着させることができる。
図5は、ドラム内の永久磁石の変形例を示す図である。
