VORRICHTUNG UND VERFAHREN ZUM ABTRENNEN VON MAGNETISCHEN ODER MAGNETISIERBAREN PARTIKELN AUS EINER FLÜSSIGKEIT

摘要

A device is provided to separate magnetic or magnetizable particles from a liquid by using a magnetic field. The device includes two limbs made of a soft-magnetic material. An air gap is provided between be two poles of the limbs. The air gap can receive one or more liquid containers. A head piece is arranged in a fixed or detachable manner on one of the two poles. One or more magnetizable bars are disposed in a fixed or movable manner on the head piece, in the vertical direction. One or more permanent magnets are arranged in a movable manner on at least one point of the device, such that a magnetic field can be produced between the two poles and the magnetic field can be activated or deactivated by moving the magnet(s). The region of the device where the movable magnet(s) are arranged is at least partially surrounded by a material that screens the magnetic field.
