Description

Elektromagnetischer Trommelscheiden mit mehreren von einer Hauptspule erregten Magnetfeldern. Bei magnetischen Trommelscheidern mit mehreren achsial nebeneinanderliegenden, über einen Teil des Kreisumfanges der Trommel sich erstreckenden Feldern wurden. bisher diese Felder durch mehrere Magnetspulen erregt. Die bekannte vorteilhafte magnetische Parallellegung mehrerer Felder, wie sie z. B, durch Patent 336766 für Walzenscheider 'eingeführt wurde, ist bisher bei Trommelscheidern nicht angewendet worden. Die ungünstigen Raumverhältnisse innerhalb der Trommel und die nebeneinanderliegenden Felder boten große Schwierigkeiten, hierfürdie Parallelregung anzuwenden. Namentlich die Streuungsverluste verboten bei Trommelscheidern die elektrisch vorteilhaftere gemeinsame Erregung mehrerer Felder.Electromagnetic drum sheaths with several of one main coil excited magnetic fields. In the case of magnetic drum separators with several axially adjacent, fields extending over part of the circumference of the drum. previously these fields were excited by several magnetic coils. The well-known beneficial Magnetic parallel application of several fields, as they are, for. B, by patent 336766 for Roll separator 'was introduced, has not yet been used in drum separators been. The unfavorable space conditions within the drum and the adjacent ones Fields presented great difficulties in using parallel excitation for this. Namely the scatter losses for drum separators forbade the electrically more advantageous common excitation of several fields.

Bei den bisherigen Ausführungen obengenannter Scheider =waren für jedes Feld eine bestimmte Amperewindungszahl erforderlich, so daß bei gleicher Magnetstärke jedes Feldes entsprechend der Anzahl der Felder ein Viälfaches von Amperewindungen erforderlich wurde. Legt man aber gemäß der Erfindung alle Felder magnetisch parallel, so sind hierfür nicht mehr Amperewindungen erforderlich als für ein Feld. Es tritt also bei dem neuen Trommelscheider eine große Ersparnis gegenüber den bisher bekannten Trommelscheidern ein, bzw. bei gleichem Durchmesser und gleichem elektrischen Energieaufwand wird eine höhere Feldstärke erzeugt.In the previous statements, the above mentioned Scheider = were for each field requires a certain number of ampere-turns, so that with the same magnetic strength of each field, corresponding to the number of fields, a fourfold of ampere-turns became necessary. But if, according to the invention, all fields are magnetically parallel, no more ampere-turns are required for this than for a field. It kicks So with the new drum separator a great saving compared to the previously known Drum separators on, or with the same diameter and the same electrical energy consumption a higher field strength is generated.

Abb. i zeigt einen Querschnitt, Abb. 2 einen Längsschnitt der Magnettrommel, Abb.3 einen Querschnitt durch einen vollständigen Scheider. -Auf dem Magnetjoch a sitzt der Magnetpol b, der in.mehrere Ansätze ausläuft. Um den Kern des Magnetjoches liegt die Spule s. Ein Mantel d, der auf den Seitenscheiben e befestigt ist, läuft um das innenliegende feststehende Magnetsystem. - Das Magnetjoch ist an den Endzapfen befestigt. -.Auf dem Mantel d liegen nebeneinander in, abwechselnder Folge Ringe von kleinem; und großem Querschnitt. Die Ansätze des Polstückes b liegen unter den dünnen Ringen, so daß die Kraftlinien vom. Polstück b durch die Ringe f hindurchtreten und an den Seiten dieser Ringe in die danebenliegenden dicken Ringe eintreten. Zwischen den Ringen wird das starke Magnetfeld gebildet. Die Kraftlinien durchsetzen die dicken Ringe g in Längsrichtung und treten aus diesen wieder in das Magnetjoch a bzw. in dessen Kern zurück. An den Übergangsstellen, wo die Kraftlinien aus den Ringen in das Joch treten, befiÜddki, sich:_,aP. letzterem Vorsprünge um den magnetisWeü Widerstand 'Möglichst zu verringern. Das Scheidegut:.,wird.,zwiscben die Ringe gebracht, wo das magnetisierbare Material festgehalten wird. - Das unmagnetisierbare Material fällt unbeeinflußt ab. Fig. I shows a cross section, Fig. 2 shows a longitudinal section of the magnetic drum, Fig. 3 shows a cross section through a complete separator. -On the magnetic yoke a sits the magnetic pole b, which ends in several approaches. The coil s lies around the core of the magnet yoke. A jacket d, which is attached to the side windows e, runs around the stationary magnet system inside. - The magnet yoke is attached to the end pin. -.On the mantle d lie side by side in an alternating sequence of small rings; and large cross-section. The approaches of the pole piece b are under the thin rings, so that the lines of force from. Pole piece b pass through rings f and enter the adjacent thick rings on the sides of these rings. The strong magnetic field is created between the rings. The lines of force penetrate the thick rings g in the longitudinal direction and emerge from them again into the magnet yoke a or into its core. At the transition points where the lines of force come from the Wrestling in the yoke, befiÜddki, yourself: _, aP. the latter protrusions around the magnetisWeü Resistance to reduce as much as possible. The material to be cut:., Will., Between the rings brought where the magnetizable material is being held. - The non-magnetizable one Material falls off unaffected.
