Separator for magnetic removal of solid particles from fluid media

Claim 1

A separator for magnetic removal of solid particles from a fluid medium, comprising: means defining a flow chamber; an inlet connection for introducing the fluid medium into said chamber; an outlet connection for discharging the fluid medium from said chamber; a rod-type ferromagnetic filter packing arranged within said chamber and comprising a plurality of elongate rods oriented so that their longitudinal axes substantially extend along the direction of flow of the fluid medium, said rods being in line contact with one another along lateral surfaces thereof during operation, to enable the fluid medium to flow through said packing, wherein said packing is composed of two parts, a first one of said parts comprising a first base and a first group of about one-half of said plurality of rods, each of said rods of said first group having one end connected to said first base and an opposite free end, a second one of said parts comprising a second base and a second group of about the other one-half of said plurality of rods, each of said rods of said second group having one end connected to said second base and an opposite free end, said first and second parts facing each other so that rods of said first group are disposed between rods of said second group, said rods being substantially cone-shaped and tapering towards the free ends thereof; and also comprising means for moving at least one of said parts towards and away from said other of said parts; and a magnetic system for magnetizing said packing.
