Abstract:
A magnetic filtration system for filtering magnetisable material from a fluid in which said magnetisable material is in suspension comprising:inlet means; outlet means; a plurality of collection units disposed between the inlet means and the outlet means; each collection unit comprising a magnet and at least two plates or plate arrays disposed on other side of the magnet so that the plates or plate arrays have opposing polarities, wherein portions of the plates or plate arrays extend beyond part or all of an edge or edges of said magnet, facing plates of each of said collection units have one or a plurality of apertures and facing pole pieces between said apertures create magnetic flux fields which define one or more collection regions of magnetic attraction and magnetisable material collection, to facilitate collection of said magnetisable material in the collection regions between exposed facing plate portions, wherein facing collection regions in each said collection unit are disposed between facing aperture such that said magnetic flux fields generated in the collection regions facilitate collection of said magnetisable material in a volume sandwiched between exposed facing plate portions, and wherein the respective plates of adjacent collection units having like polarity are disposed adjacent to one another so as to substantially restrict the collection of said magnetisable material to the collection regions.
