Tellermagnetscheider mit gleich- oder gegenpoligen Ringanordnungen bei stehender oder liegender Achse sind bekannt. Bei der Scheidung von feinstkörnigem Gut wird durch die Haftung der Magnetteilchen aneinander das Nichtmagnetische zwischen diesen festgehalten undkann nicht genügend durch Schleuder- oder Blaswirkung aus dem Gemenge ausgetragen werden.Disc magnetic separator with ring arrangements of the same or opposite polarity with a vertical or horizontal axis are known. When separating very fine-grained goods, the magnetic particles adhere to one another the non-magnetic held between them and cannot be sufficiently carried out by centrifugal or Blowing effect can be discharged from the mixture.
Die Anwendung von Zinken, die durch das magnetische Gut greifen, ermöglicht eine weitgehende Scheidung, die durch Ausschleudern und Fortblasen der Gangart abgeschlossen wird.The use of prongs that grip through the magnetic material enables extensive separation, which is completed by ejecting and blowing the gait.
Ergänzt kann dieses Auskämmen dadurch werden, daß man grobe Körnungen, z. B. Kies, etwa pneumatisch, in das magnetische Gut hineinmischt, aus dem es durch Ausschleudern leicht hinausgetragen wird und dabei andere unmagnetische Verunreinigungen mitnimmt. In der Zeichnung ist inThis combing out can be supplemented by using coarse grains, e.g. B. gravel, e.g. pneumatic, mixed into the magnetic material, from which it is easily carried out by being thrown out and takes other non-magnetic impurities with it. In the drawing, in
Abb. 1 ein solcher Tellermagnetscheider im Teilschnitt, inFig. 1 such a disk magnet separator in partial section, in
Abb. 2 eine Abrollung der Ringflächen dazu, inFig. 2 shows a rolling of the ring surfaces, in
Abb. 3 ein schematischer Längsschnitt in beispielsweiser Ausführung dargestellt.Fig. 3 shows a schematic longitudinal section in an exemplary embodiment.
Die abwechselnd NS-gepolten umlaufenden Magnetringe 1 überragen leicht die unmagnetischen Zwischenlagen 2. Das feinkörnige Gemenge wird durch Rohr 3 aufgeschüttet oder aufgeblasen und unter dem Mantelblech 4 durch Schlitze 5 von den magnetischen Ringen etwa kraftlinienartig bei 7 festgehalten. Der unmagnetische Feinstaub wird, soweit er nicht durch die Kraftlinien 7 festgehalten wird, durch die Schleuderwirkung des sich drehenden Ringaggregates ausgeschleudert und passiert praktisch die feststehenden Rost- oder Siebstäbe 6, die die Kammzinken 8 halten, unter dem Schutzblech, von wo er durch Gas- oder Luftbewegung in ein Absaugrohr 9 ausgetragen wird.The rotating magnetic rings 1 with alternating LV polarity protrude slightly beyond the non-magnetic intermediate layers 2. The fine-grained mixture is poured or inflated through pipe 3 and placed under the jacket plate 4 held by slots 5 of the magnetic rings approximately like a force line at 7. Of the Non-magnetic fine dust, as far as it is not held by the lines of force 7, is caused by the centrifugal effect of the rotating ring aggregate and practically passes the stationary ones Grate or sieve bars 6, which hold the comb teeth 8, under the protective plate, from where it is by gas or Air movement is discharged into a suction pipe 9.
Das verbleibende unmagnetische Gut wird unter wiederholtem Zerreißen der Kraftlinien 7 immer weiter aus dem magnetischen Teil ausgetragen und vom Gasstrom mitgenommen.The remaining non-magnetic material becomes with repeated tearing of the lines of force 7 always further discharged from the magnetic part and carried along by the gas flow.
Zum Erleichtern der endgültigen Austragung kann man gröbere Körnungen, z. B. Kies, aus Rohr 10 ins feinkörnige magnetische Material hineintreiben, von wo es durch Schleuderwirkung unter Mitnahme von restlichem Unmagnetischen ausgetragen und etwa durch Rohr 11 abgezogen wird.To facilitate the final discharge, you can use coarser grain sizes, e.g. B. gravel, from pipe 10 ins drive fine-grained magnetic material into it, from where it is driven by centrifugal action with the entrainment of remaining non-magnetic is discharged and withdrawn through pipe 11, for example.
13 sind beliebige feststehende Magneten zum Induzieren der Ringpole 1 ihnen gegenüber, gegebenenfalls mit Spulen 14 betrieben; diese Magneten werden axial von der Drehachse 15 des Magnetscheiders festgehalten. 13 are any fixed magnets for inducing the ring poles 1 opposite them, if necessary operated with coils 14; these magnets are held axially by the axis of rotation 15 of the magnetic separator.
