Definitions

  • the invention relates to a magnetic separator for separating magnetic particles, in particular from volatile dust.
  • a magnetic separator is known from PL-A-87 216, in which the poles form a working air slot in the form of a trapezoid.
  • a conveyor belt which carries the magnetic dust deposited thereon out of the area of the magnetic field, is slidably arranged in this slot at the location of the greatest induction of the magnetic field. The arrangement of the movable belt in the area of the flowing dust lowers the dust-tightness and the functionality of the device.
  • a magnetic separator is known from PL-A-80 412, the ferromagnetic rotor of which has ferromagnetic teeth on its surface, which are distributed on a helical line.
  • the material to be cleaned is placed on the rotary wheel.
  • the ferromagnetic particles contained in the substance accumulate in the air slot between the teeth of the impeller and the poles of the magnets, i.e. where the magnetic field strength is greatest.
  • these points move towards one end of the gyroscope and thus the ferromagnetic particles also move.
  • the magnetic separator according to the invention comprising a ferromagnetic roller, on the surface of which teeth are arranged along a helix, and which is arranged between magnetic poles, is characterized in that a non-magnetic protection is placed on the roller, which is connected to the plates that hold the magnetic poles form, which forms working slots.
  • the roller or the cylinder can have additional recesses which cut through the helix of the teeth.
  • the arrangement between the plates of at least two cylinders one above the other increases the dust separation effect.
  • the non-magnetic protection can be profiled into a shape that corresponds to the radii of the cylinders.
  • Projections with a triangular cross section are preferably arranged in the dust flow zone, one of the sides of the triangle abutting the plate surface and the height of the projection being smaller than the width of the working slot. These projections produce an inhomogeneous magnetic field in the entire area of the work area.
  • the separator is characterized in that the plates which form the magnetic poles, together with the cylinders and working slots, are arranged symmetrically with respect to the excitation coil.
  • rollers of the cutter are preferably arranged in at least two vertical rows separated from one another by a working slot, magnetic inserts being arranged in the working slot, which form the triangular dust flow zones.
  • Such a roller arrangement makes it possible to increase the throughput of the cutter with the same plate thickness.
  • a fundamental advantage of the application of the invention is the maintenance of a high level of dust tightness and functionality by removing the movable elements from the area into which the dust flows.
  • high throughput and separation efficiency are ensured by generating an inhomogeneous magnetic field in the entire space of the working slots with the same current consumption.
  • the dust to be separated is fed through an inlet 7 to the flow zones, which are separated by strips attached to the plates 1. It is divided into two parts in the working slots 4 under the action of the magnetic field, the non-magnetic dust falling to an outlet 8 and the magnetic dust being deposited on the non-magnetic protection 3 at the level of the axes of the rollers 2. By rotating the rollers 2, the magnetic dust is transported along the axes thereof to the end of the slots 4, where it falls into the outlet of the ferromagnetic concentrate.
  • a roller is shown with additional recesses 14 which cut through the helix of the teeth.
  • inserts or projections are attached to the plates, which protrude from the working slots 4 and the dust flow zones 10.
  • the plates 1, which play the role of the magnetic poles, together with the rollers 2, working slots 4 and 11 and magnetic inserts 9, 12 are arranged symmetrically with respect to the excitation coil 5.
