High-gradient magnetic filter and method for the separation of weakly magnetisable particles from fluid media ( 2 ) in a circuit, embodied as a compact, low-maintenance unit with low repair requirements, comprising a housing ( 1 ), for the high gradient magnetic filter, with means for directing the flowing medium ( 2 ) in a pipe system with a feed ( 3 ) and return ( 4 ), a magnetic circuit ( 5 ), forming the high-gradient magnet filter in which at least one filter ( 8 ) is arranged in a filter chamber ( 7 ), formed between the pole faces ( 6 ) of the magnetic circuit ( 5 ), through which the medium ( 2 ) for purification flows, at least one permanent magnet ( 9 ), arranged in the magnetic circuit ( 5 ), for generation of a magnetic field between the pole faces ( 6 ). The magnetic circuit ( 5 ) is separated and sealed off from the flowing medium, the magnetic field between the pole faces ( 6 ) may be alternately switched on and off by means of the permanent magnet ( 9 ), whereupon the discharge and the operation of separating off the particles from the flowing medium may be achieved simply and economically. |
