    • 专利摘要:
    An arcuate shaped magnetic system is housed in a fixed cryostat within a rotating drum. A slurry containing magnetizable particles is charged into an operating area defined by the magnetic system at the lower part of the drum and magnetic particles adhering to the drum are removed as the drum rotates the same to a discharge location. The cryostat has an outer wall which conforms to the shape of the drum and houses a sector-shaped refrigeration tank. The refrigeration tank has an arcuate wall section conforming to the shapes of the cryostat wall and the drum and is positioned in close proximity to the outer cryostat wall only in the operating area in order to minimize inward heat transfer.

    FIELD OF THE INVENTION The invention relates to the field of mineral processing.
    A magnetic drum separator is known, which includes a non-magnetic drum, a magnetic system located inside the drum, a dewatering device, a power supply and discharge pipe Ij.
    A magnetic drum separator is also known, which includes a drum, a cryostat placed inside the drum, a tank with refrigerant, placed inside a cryostat and a sector-shaped magnetic system in cross section, placed in a tank with refrigerant and made of superconducting coils mounted on the frame, inside and outside the surface of which is made in an arc and placed axially to the drum, the power supply and discharge pipes 2.
    A disadvantage of the known separators is their low productivity.
    The aim of the invention is to increase the performance of the separator.
     This is achieved by the fact that the superconducting coils are fixed on the outer surface of the frame and image (yony to the surface of the drum of the same name.

    poles, the coils have an ellipse or raster and are oriented by the longitudinal axis along the frame axis, and by the transverse axis 5 along the arc yrma, the transverse axis of the coil winding to the longitudinal axis of the winding decreases from internal coils to external coils, and the distance between the coils of the coil in the direction of the longitudinal axis, there is more distance between them in the direction of the transverse axis; the cryostat is made in the form of a cylinder, with the outer wall of the nostrone and the drum made of one piece. 15 In FIG. 1 shows a front separator, a general view, in FIG. 2 a magnetic system with coils in the form of an ellipse; in fig. 3 - magnetic system with coils in the form I & racetrack, in FIG. 4 shows section A-A in FIG. 3, in FIG. 5 - placement of turns in the winding coils; on fig.b location of the coils in the frame.
    The separator includes a drum 1, 28 cryostat 2, a capacity 3 with refrigerant, a magnetic system consisting of a roma 4, the outer and inner surfaces of which are made in an arc, and superconducting coils 5, 30 placed on the outer surface
    rma 4. The separator also has a bath 6, a supply pipe 7, a discharge device 8, a discharge pipe 9 for the magnetic fraction, a discharge device 10 for the non-magnetic fraction, cores 11, a horn 12 regulator, turns 13-16 of the winding coil, the ratio of the transverse axis which to the longitudinal la / b) decreases from internal coils to external coils and the distance between the winding coils in the direction of the longitudinal axis is greater than the distance between them in the transverse axis direction, the coils 5 are connected to a voltage source so that a single current is excited in them Board, that allows to create a magnetic field in the separation zone, where the field lines have the direction shown in FIG. 2, 3, and 4. Making the coils in the form of an ellipse or a raster, orienting them with the longitudinal axis along the generatrix of the chassis and the transverse axis along the arc surface of the chassis and exciting current in one direction in them, creates in the separation zone a magnetic field of high intensity, uniform across the width of the working area.
    The separator works as follows. . . .
    The source material is 1; the pipe 7 is fed into the bath 6 into the zone of action of the magnetic field created by the electromagnetic coils 5. The non-magnetic particles are unloaded using the device 10, the magnetic particles are attracted to the surface of the drum 1 and are rotated to the unloading device 8 made in the form of the scraper, and then unloaded through the pipe 9.
    Fastening the superconducting coils on the outer surface of the chassis so that they face the drum surface with the same poles, making the coils in the form of an ellipse or a cross-stitch, orienting them with the longitudinal axis along the generatrix of the chassis and the transverse axis along the arc of the chassis, increase the separator's performance by in the separation zone magnetic field of high intensity, uniform across the width of the working area.
