Title: Improvements in or relating to magnetic separators
IPC: B03C1/14
Filed: 1946-06-05
Abstract: 612,888. Magnetic-separators. NEILL & CO. SHEFFIELD), LTD., J., and BOWER, W. L. June 5, 1946, No. 17050. [Class 72] In a magnetic separator for extracting ferrous particles from liquids of the type comprising a rotary member having a separating surface to one side of which a stream of liquid containing the particles is fed and on the other side of which is disposed one or more magnets, the rotary member is driven by the movement of the liquid fed to and co-acting with a portion of the separating surface which is subjected to a magnetic-field to attract ferrous particles from the liquid and means are provided for subjecting an adjacent portion of the separating surface to another magnetic-field to repel ferrous particles therefrom, the two portions of the separating surface passing successively through these two fields. The separating surface may be a drum freely mounted and provided with vanes which may be adjustable extending outwardly from its cylindrical surface, or may be one or two discs provided with vanes, the liquid in either case being directed to impinge on the vanes to cause rotation. As shown in Fig. 1, the liquid enters at 26 to impinge on magnetic vanes 18 adjustably attached to side discs 16 to which is also attached the non-magnetic separating surface 14. The liquid causes the drum to rotate and passes through the gaps between the vanes 18 and the drum surface 14, the magnetic particles extracted being retained on the drum surface by the arcuate fixed magnets 23 to be carried round and either fall freely or be ultimately repelled from the drum by the magnet 24 having its poles reversed with respect to those of the magnets 23. Filtered liquid thus leaves by the exit 31 and ferrous particles at 32. In a modification, Fig. 3 (not shown), two sets each of oppositely inclined vanes are arranged adjacent the walls 16 of the drum each set having a separate supply chute, and a rubber wiper bears on the clear central portion of the drum surface between the sets of vanes to remove magnetic particles. In the form shown in Fig. 5, a non- magnetic disc 41 carries vanes 46 which may be curved and adjustable, the filtered liquid leaving at 52 and the magnetic particles retained on the disc by the annular magnets 43 of Wand U section being delivered at 53, its removal therefrom being aided by centrifugal force in addition to the repulsion by magnets 44. This arrangement is said to be particularly suitable for high speed rotation. In a modification of this type the vanes 46 may be enclosed between two discs 41, each having its own set of magnets, in which case a central steel rib may be provided in the vane space as a flux intensifier. The magnets may be either permanent or electro-magnets. Specifications 534,895 and 535,008 are referred to.
