Description

Die Erfindung betrifft eine Verbesserung des Magnetscheider nach Patent 306172, der aus zwei der mehreren mit Abstand nebeneinander auf einer gemeinsamen Achse sitzenden, von einer gemeinsamen Austragtrommel umgebenen scheibenförmigen Polen besteht, und bei dem der Abstand je zweier zusammenwirkender Kanten der von der Austragtrommel umgebenen Pole voneinander in Richtung· des Trominelumlaufes zu- oder abnimmt. Bei solchen Scheidern können infolge der seitlichen Abweichung der anziehenden Scheibenpolkanten von der Drehungsebene die angezogenen-' Erzteilchen während eier Trommeldrehung eine Seitenbewegung in Richtung der Trommelachse ausführen, weil sie der Schräge dieser Scheibenpolkanten folgen müssen und es liegt die Gefahr nahe, daß die angezogenen Gutsteilchen infolge dieser Seitenbewegung vorzeitig abfallen.The invention relates to an improvement of the magnetic separator according to patent 306172, the from two of the several seated at a distance next to each other on a common axis, from a common discharge drum surrounded disc-shaped poles, and in which the distance between two interacting edges of the Discharge drum surrounded poles from each other in the direction of the drum circulation or decreases. With such separators, as a result of the lateral deviation of the attractive Disc pole edges from the plane of rotation the attracted- 'ore particles during When the drum rotates, perform a lateral movement in the direction of the drum axis because they have to follow the incline of these disc pole edges and there is a risk of that the attracted good particles fall off prematurely as a result of this lateral movement.

Die Erfindung vermeidet diesen Übelstand dadurch, daß auf der Trommel über den Polen magnetisierbare, durch unmagnetisierbare Stoffe voneinander getrennte Stücke von in Richtung der Trommelachse gleicher Abmessung ringförmig angeordnet sind, die mit den festen Scheibenpolen zu- oder abnehmende Felder bilden. Dabei liegen die Kopfflächen dieser magnetisierbar«! Stücke in senkrecht zur Trommelachse liegenden Ebenen. Diese Ringstücke können auch in Richtung der Trommelachse verschiebbar angeordnet sein.The invention avoids this drawback in that on the drum on the Poles of magnetizable, separated by non-magnetizable materials pieces of are arranged in a ring in the direction of the drum axis of the same dimension, with the fixed disc poles form increasing or decreasing fields. The head surfaces are located here this magnetizable «! Pieces in planes perpendicular to the drum axis. These Ring pieces can also be arranged displaceably in the direction of the drum axis.

In Fig. ι ist ein solcher Scheider im Längsschnitt und äußerer Ansicht dargestellt. Fig. 2 zeigt den Querschnitt desselben.In Fig. Ι such a separator is in longitudinal section and external view. Fig. 2 shows the cross section of the same.

Auf dem Magnetkern α sind die Pole 1 befestigt, die aus in der Richtung des Trommelumlaufes an Breite zunehmenden Scheiben bestehen und zwischen denen die Wicklungen c sitzen. Die Trommel e dreht sich um die Scheibenpole 1. Auf der Trommel sind über jedem Scheibenpol Ringstücke 2 aus magnetisierbarer!! Stoff abwechselnd mit solchen aus unmagnetisierbarem Stoff ringförmig um den ganzen Trommelumfang herum angeordnet, so daß die Kraftlinien von dem einen Pol durch die Trommel und die je^veilig vor dem Pol ' vorbeigehenden, magnetisierbaren Ringstücke 2 hindurch, durch den Luftraum nach den entsprechenden Ringstücken 2 der benachbarten Pole und weiter durch den Mantel hindurch in diese Pole selbst verlaufen. Die magnetisierbarer! Ringstücke 2 sind über jedem Pol von unter sich gleicher Breite und ihre Kopfflächen liegen in senkrecht zur Achse liegendenOn the magnetic core α , the poles 1 are attached, which consist of disks increasing in width in the direction of the drum rotation and between which the windings c sit. The drum e rotates around the disc poles 1. On the drum are ring pieces 2 made of magnetizable !! Substance alternating with non-magnetizable material arranged in a ring around the entire drum circumference, so that the lines of force from one pole through the drum and the magnetizable ring pieces 2 passing in front of the pole, through the air space to the corresponding ring pieces 2 of the neighboring poles and further through the jacket into these poles themselves. The more magnetizable! Ring pieces 2 are above each pole of the same width and their head surfaces are perpendicular to the axis

Claims

Levels. Therefore, the good they attract is despite the inclined position of the pole edges does not cause a lateral movement on the drum shell / as is to be expected according to the main patent. The cross-sectional shape of the magnetizing ' ble ring pieces is expediently chosen so that the pieces in between made of non-magnetizable material such as cement

ίο and the like, without special fasteners. be held. The magnetic strength of the ring pieces 2 will, apart from the extent of the excitation of the poles by the coils c , correspond to the respective pole width passing through. The ring pieces can also consist of two parts 9 and 10 each, which are displaceable in the direction of the drum axis. They are then appropriately provided with overlapping approaches.

By using the alternately magnetizable and non-magnetizable Ring pieces existing rings of consistently the same width in the magnetic separator According to patent 306172, not only is the sideways movement of the attracted goods in Direction of the drum axis avoided, instead it is given as the pieces of each pole have the same polarity with each other, at the same time also magnetizing the ring piece to ring piece of the same ring and thus an undesirably wide discharge of the attracted goods out of the magnetic field, as it is, for. B. when applied ■ closed, completely magnetizable rings occurs, effectively prevented.

If corresponding auxiliary po! E are arranged between the poles, then the ones previously described are assembled rings to be attached over this on the drum.

Godfather τ-An Proverbs:

ι. Magnetic separator according to patent 306172, characterized in that on the discharge drum over each pole or ' corresponding auxiliary pole, a ring is arranged, which consists of individual ring pieces of alternately magnetizable and non-magnetizable material.

2. Magnetic separator. according to claim 1, characterized in that the rings in Can be shifted in the direction of their axis.

3. Magnetic separator according to claim 1 and 2, characterized in that the dadurcli Rings of appropriately overlapping parts (9 and 10) are made in can be moved in the axial direction.
