Abstract:
1. A device for magnetic separation of a fluid containing first particles of magnetic or magnetizable material and second particles of non-magnetic or non-magnetizable material to be separated, the device comprising: at least two magnet arrangements, each configured to generate a magnetic induction, the at least two magnet arrangements arranged flush with one another with respect to a center axis, wherein neighboring magnet arrangements have an opposing pole arrangement and are disposed spaced at a distance d from one another for generating a cusp field, and at least one conveying line configured to transport the fluid, wherein longitudinal axis of the at least on conveying line, at least in the area of the magnet arrangements, is routed through a plane aligned perpendicular to the center axis between neighboring magnet arrangements, wherein the at least one conveying line has at least one branch downstream of the center axis in the direction of transport of the fluid, and wherein a cross section of the least one conveying line is disposed entirely in one area in which a product of the magnetic induction of the respective magnet arrangement and a gradient of the respective magnetic induction is positive, and wherein an area of a wall of the conveyor line, which is located at a maximum or minimum perpendicular distance from the center axis, runs along a line at which the gradient of the respective magnetic induction is equal to zero.
