A cylindrical passage 2 having a fluid inlet 5 at the top and a fluid outlet 3 and a powder outlet 4 at the bottom.
A cylindrical magnetic field generating device 7 using a permanent magnet is arranged concentrically within the interior, and this device 7 is connected to gears 7a,
It is connected to a rotational drive source M via Ma (or chain or belt), and can be rotationally driven by this rotational drive source M. Further, in the passage 2, a scraper 8 is provided at a position corresponding to between the fluid outlet 3 and the powder outlet 4, and is in sliding contact with the outer circumferential surface of the magnetic field generator 7.

体が集中化、高濃度化して取り出される。 Now, when the fluid to be treated (undiluted solution) W 0 mixed with magnetic powder is introduced from the inlet 5, the magnetic powder is attracted and adsorbed onto the surface of the magnetic field generator 7. Since the magnetic field generator 7 is rotated counterclockwise by the motor M, the magnetic powder is transferred in the F direction. The transferred magnetic powder is peeled and separated from the surface of the magnetic field generator 7 by the scraper 8, and is transferred toward the take-out port 4, where the magnetic powder is concentrated and concentrated as W 2 and taken out. It can be done.
一方、処理すべき流体W0は流体出口３に到達

A fluid containing magnetic powder may be brought into contact with the inner peripheral surface.

A plurality of nine rows of permanent magnets inclined with respect to the axis are embedded and fixed in the inner circumferential surface of the magnetic field generating device 11 so as to be arranged and configured in the same manner as described above. Furthermore, a flow path 12 having a fluid inlet 15, an outlet 13 and a particle outlet 14 is arranged concentrically inside the magnetic field generator 11. Also in this configuration, when the magnetic field generator 11 is rotationally driven by the motor M, the magnetic powder attracted by the magnetic field of the magnetic field generator 11 is separated and transferred to the outlet side. The fluid W1 from which the magnetic powder has been removed flows out from the outlet 13 and is used again as a coolant.
