ABSTRACT:
A magnetic separator for fluids has a non-magnetic container which is divided into a trapping portion and an accumulating portion. A fluid containing magnetic particles to be removed therefrom is introduced via an inflow pipe and discharged via a discharge pipe located in the top and bottom, respectively, of the trapping portion. A pair of electrodes are mounted in opposite end walls of the container, and a plurality of magnetizable wires are strung across the container in parallel between the electrodes. The electrodes are electrically connected to a mechanism for generating alternating current whose frequency components are harmonics of the fundamental frequency of vibration of the magnetizable wires. The container is situated between a pair of magnets which produce a magnetic field whose strength increases from the trapping portion to the accumulating portion. The magnetic field strength is preferably a maximum in the accumulating portion at a position removed from the end wall of the accumulating portion.
