Definitions

  • the present invention relates to a magnetic separator with two rotating oppositely polarized magnetic drums, which form a working air gap between them, with directionally magnetized block magnets with oppositely arranged magnetic poles arranged on two adjacent end faces of the magnetic drums in a closed magnetic circuit.
  • a magnetic separator has become known with two revolving, oppositely polarized magnetic drums, which form a working air gap between them, whereby directional magnetized block magnets with opposing magnetic poles are arranged on two adjacent magnetic drums, on one side of their poles by soft iron pieces are connected to one another, the drums each being arranged in a housing, which have sliding plates tapering the inlet and widening the outlet in the working air gap and have circumferentially distributed grooves in the radial direction and grooves in the axial direction.
  • a magnetic roller table is known from BE-A-851 305, in which four permanent block magnets are arranged in a closed magnetic circuit, which are connected to one another in pairs on the underside of unequal polarity by soft iron connecting pieces and have pole shoes on the top of their poles, in which are designed as axes for the conveyor rollers of the roller table soft iron parts.
  • the object of the invention is to achieve a better efficiency by keeping the stray fields as small as possible and avoiding scattering outside the effective range as far as possible.
  • the soft iron parts are arranged in the interior of the drums as axes and are designed in the form of a segment in cross section.
  • the magnetic separator consists of two iron magnetic drums 1 and 2 and a magnet system with block magnets 3, 4 and 5, 6 arranged on two adjacent end faces of the magnetic drums 1, 2, with oppositely arranged magnetic poles on one side of their poles are connected to each other by soft iron pieces 7 and 8 and have pole shoes 9, 10 and 11, 12 on the other side of the poles.
  • the soft iron parts which are designed as axes 13 and 14 for the rotating magnetic drums 1 and 2 and which are mounted in ball diameters 15, extend.
  • the magnetic flux of the block magnets 3, 4 and 5, 6 is in an absolutely closed circuit, the magnetic field or the working air gap 16 is in the gap between the magnetic drums 1 and 2.
  • the magnetic drums 1 and 2 are arranged in a housing 17 and 18, respectively.
  • the housings 17 and 18 have 16 sliding plates 19 and 20 in the working air gap, which together form a tapering inlet and an expanding outlet on both sides of their partial encirclement of the drums 1 and 2.
  • the magnetic drums 1 and 2 have on their circumference radially distributed and axially extending grooves 21 filled with non-magnetic material, or according to FIG. 3 a circumferential star-shaped circumference.
  • edges 22 formed in this way cause an increased magnetic radiation, as a result of which the separating effect in the working air gap 16 formed by the sliding plates 19 and 20, which the separator happens well vertically from top to bottom, is significantly improved.
  • the axes 13 and 14 are segment-shaped over the length of the magnetic drums 1 and 2.

Abstract

Separateur magnetique pour l'elimination de particules fines, notamment faiblement magnetisees, comprenant deux tambours magnetiques, polarises en sens inverse, en rotation et formant entre eux une fente de travail (16) et avec deux aimants (3, 4, 5, 6) fixes de chaque cote frontal des tambours magnetiques et formant un circuit magnetique ferme, les deux aimants etant relies par paire d'un cote de leurs poles par des pieces de fer doux (7, 8) avec des poles magnetiques differents et presentant des cosses de l'autre cote (9, 10; 11, 12), dans lesquels des particules de fer doux sont logees pour former des axes (13, 4), les tambours (1, 2) se trouvant chacun dans un logement presentant dans la fente de travail (16) des passages glissant pour reduire l'entree et elargir la sortie et qui sont distribues radialement sur leur pourtour et possedent une gorge axiale (21) ou presentent en coupe un pourtour en etoile. De cette maniere, on obtient un systeme ferme nettement moins dispersant que ce qui est connu et qui elimine largement la dispersion externe et engendre un champ magnetique plus fort dans la fente de travail.

Claims (1)

  1. Séparateur magnétique comportant deux tambours magnétiques tournants de polarité opposée, qui forment entre eux un entrefer de travail, des aimants (3, 4; 5, 6) en forme de blocs aimantés directionnellement, qui sont disposés dans un circuit magnétique fermé au niveau de chacune des deux faces frontales situées côte à côte des tambours magnétiques (1, 2), qui comportent des pôles magnétiques orientés en sens opposé, et qui d'un côté de leurs pôles sont couplés entre eux par des parties en fer doux (7, 8) et de l'autre côté comportent des pièces polaires (9, 10; 11, 12) dans lesquelles sont montées des pièces en fer doux se présentant sous la forme d'arbres (13, 14), les tambours (1, 2) étant disposés dans des boîtiers respectifs (17, 18), qui comportent des tôles de glissement (19, 20) rétrécissant l'entrée et élargissant la sortie dans l'entrefer de travail (16), et possédant une périphérie en forme d'étoile en section transversale ou des rainures (21) s'étendant suivant la direction axiale et réparties radialement sur leur périphérie, caractérisé en ce que les pièces en fer doux sont disposées à l'intérieur des tambours (1, 2) en tant qu'arbres (13, 14) et ont la forme d'un segment en section transversale.
