Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Vorrichtung mit einem von einem Motor betriebenen System zum Abtrennen von nichtmagnetisierbaren Metallen, insbesondere NE-Metallen, und vorhandenen Fe-Anteilen aus einer Feststoffinischung mittels einer auf einem Stator gelagerten und um diesen rotierenden Trommel, in der ein rotierender, mit Permanentmagneten bestückter Magnetrotor exzentrisch angeordnet und im Stator gelagert ist. Die Erfindung betrifft ferner ein Verfahren zum Betreiben der Vorrichtung.The invention relates to a device with a system operated by a motor for separating non-magnetizable metals, in particular non-ferrous metals, and existing Fe fractions from a solids mixture by means of a drum mounted on a rotating and rotating drum, in which a rotating, with permanent magnets equipped magnet rotor is arranged eccentrically and stored in the stator. The invention further relates to a method for operating the device.

Stand der TechnikState of the art

Derartige gattungsähnliche Vorrichtungen bzw. Verfahren sind zum Abtrennen von nichtmagnetisierbaren Metallen bekannt.
Schon die DE-C1-38 23 944 schlägt ein in einer Gurttrommel mit höherer Drehgeschwindigkeit als die der Gurttrommel angetriebenes Magnetsystem vor, bei der der Außendurchmesser des Magnetsystems geringer als der lichte Innendurchmesser der Gurttrommel und vor allen Dingen das Magnetsystem in der Gurttrommel exzentrisch angeordnet ist.Such generic devices or methods are known for separating non-magnetizable metals.
Already the DE-C1-38 23 944 proposes a belt drum in a higher rotational speed than the belt drum driven magnet system in which the outer diameter of the magnet system is less than the clear inner diameter of the belt drum and, above all, the magnet system in the belt drum is arranged eccentrically ,

Weiterentwickelt wurde diese Vorrichtung gemäß der DE-C1-38 17 003 dahingehend, daß der exzentrisch angeordnete Magnetrotor in seiner Lage im Quadranten der Materialabwurfzone und damit der Wirkbereich des vom Magnetrotor erzeugten Wechselmagnetfeldes durch radiales Verstellen einstellbar ist.This device has been further developed according to DE-C1-38 17 003 to the effect that the eccentrically arranged magnetic rotor is adjustable in its position in the quadrant of the material discharge zone and thus the effective range of the alternating magnetic field generated by the magnetic rotor by radial adjustment.

Um den Trenneffekt aus eingangs beschriebenen Feststoffgemischen, nach vorheriger Separierung der Fe-Anteile, hinsichtlich, der NE-Metalle zu verbessern, wurde gemäß der DE-C2-195 21 415 durch eine konstruktive Verknüpfung bewährter technischer Mittel, und zwar vom Aufgabebereich des Feststoffgemisches über den weiteren Förder- und Abwurfbereich bis hin zu den durch die Wurfparabeln gebildeten Trennzonen, erreicht, daß sich die Sortenreinheit in den einzelnen Materialfraktionen weiter konzentriert.In order to improve the separation effect from the above-described solid mixtures, after prior separation of the Fe fractions, in terms of, the non-ferrous metals was, according to DE-C2-195 21 415 by a constructive linkage of proven technical means, namely from the task area of the solid mixture over the further conveying and discharge area up to to the separation zones formed by the throwing parabolas, ensures that the purity of the variety in the individual material fractions is further concentrated.

Die Suche nach Wertstoffen im Recyclingbereich ist noch nicht abgeschlossen, und es stellen sich neue Probleme.The search for recyclables in the recycling sector is not yet completed and new problems arise.

Beim Abtrennen von nichtmagnetisierbaren Metallen wie NE-Metallen aus Feststoffmischungen, die nach dem Separieren der Fe-Fraktion aus z.B. einer Shredderleichtfiaktion gewonnen wird, ist es erforderlich, die Sortenreinheit der NE-Metallftaktionen wegen des zu erzielenden Preises zu erhöhen aber auch Massenströme von Feststoffmischungen rationell in die verwertbaren Fraktionen zu trennen.When separating non-magnetizable metals such as non-ferrous metals from solid mixtures which, after separating the Fe fraction from e.g. a Shredderleichtfiaktion is obtained, it is necessary to increase the purity of the variety of non-ferrous metal operations because of the price to be achieved but also to efficiently separate mass flows of solid mixtures into the usable fractions.

So zeigt die Praxis, daß die eingangs beschriebenen Feststoffmischungen immer noch - trotz vorheriger Fe-Separierung - Reste von Fe enthalten.Thus, the practice shows that the solid mixtures described above still - despite prior Fe separation - contain residues of Fe.

Das Bewältigen von Massenströmen an Feststoffmischungen über eingangs beschriebene Vorrichtungen führte u.a. zu einer extrem breiten Auslegung der Trommeln und den darin rotierenden, exzentrisch angeordneten Magnetrotoren. Daraus ergaben sich Schwingungen, die sich sowohl im Konstruktionssystem als auch im Hinblick auf den Trenneffekt negativ auswirkten.Overcoming mass flows of solid mixtures via devices described in the introduction led u.a. to an extremely broad interpretation of the drums and the rotating, eccentrically arranged magnetic rotors. This resulted in vibrations that had a negative effect both in the construction system and in terms of the separation effect.

Darstellung der ErfindungPresentation of the invention

Die Erfindung stellt sich die Aufgabe, eine Vorrichtung der eingangs genannten Gattung zu schaffen, die den Anforderungen der industriellen Trennung von nichtmagnetisierbaren Metallen und noch vorhandenen Fe-Anteilen aus Feststoffmischungen, wie z.B. nach der Separierung der Fe-Fraktion aus der Shredderleichtfraktion gewonnen, gerecht wird. Dabei soll die Sortenreinheit vor allem der NE-Metalle gewährleistet sein, d.h., daß aber auch die noch vorhandenen Fe-Anteile für sich zu separieren sind. Insbesondere ist dabei das Problem zu lösen, die bei extrem breiten Trommeln und ggf. damit verbundenen Förderbandsystemen auftretenden Schwingungen und entsprechende Resonanzen im Konstruktionssystem weitgehend zu eliminieren. Das zugehörige Verfahren soll die Gewährleistung der Sortenreinheit unterstützen.The invention has as its object to provide a device of the type mentioned, which meets the requirements of the industrial separation of non-magnetizable metals and still existing Fe contents of solid mixtures, such as obtained after separation of the Fe fraction from the shredder light fraction , The variety purity should be ensured especially of non-ferrous metals, ie, but that also the remaining Fe fractions are to be separated for themselves. In particular, the problem is to be solved, the oscillations occurring in extremely wide drums and possibly associated conveyor belt systems and corresponding resonances in the construction system largely to eliminate. The associated procedure is intended to support the guarantee of varietal purity.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Gemäß Fig. 1 und 2 besteht die erfindungsgemäße Vorrichtung aus einer auf einem Stator 1 gelagerten und um diesen rotierenden Trommel 2, in der ein rotierender, mit Permanentmagneten 3 bestückter Magnetrotor 4 exzentrisch angeordnet und im Stator 1 gelagert ist. Die Funktion und Wirkungsweise einer derartigen Vorrichtung zum Abtrennen von nichtmagnetisierbaren Metallen aus einer Feststoffmischung ist ausführlich in den zum Stand der Technik zitierten Schriften erläutert.According to Fig. 1 and 2, the device according to the invention consists of a mounted on a stator 1 and rotating around this drum 2, in which a rotating, with permanent magnets 3 fitted magnet rotor 4 is arranged eccentrically and stored in the stator 1. The function and mode of operation of such a device for separating non-magnetizable metals from a solid mixture is explained in detail in the documents cited in the prior art.

Da bei derartigen Vorrichtungen zur Beeinflussung des Trenneffektes der Winkel durch Schwenken des im Stator 1 exzentrisch angeordneten Magnetrotors 4 zu verstellen ist, wird erfindungsgemäß ein Ausgleichgewicht 1.1 zum Massenausgleich am Stator 1 angeordnet. Dieses Ausgleichgewicht 1.1 erfüllt zugleich die Funktion eines Schwingungsdämpfers, insbesondere bei extremen Breiten der Trommel 2 bzw. eines Förderbandsystems 5, 5.1, wie in den Fig. 3, 4 und 5 dargestellt.Since, in such devices for influencing the separation effect, the angle is to be adjusted by pivoting the eccentrically arranged in the stator 1 magnetic rotor 4, a balance weight 1.1 is arranged according to the invention for mass balance on the stator 1. This balance weight 1.1 also fulfills the function of a vibration damper, in particular in the case of extreme widths of the drum 2 or a conveyor belt system 5, 5.1, as shown in FIGS. 3, 4 and 5.

Um aus dem Feststoffgemisch neben den üblicherweise abzutrennenden nichtmagnetischen Metallen auch die noch vorhandenen Fe-Anteile abzutrennen, ist das Ausgleichgewicht 1.1 in einer Baueinheit mit einem Transportmagnet 1.2 bzw. als Magnet ausgebildet, wobei es in seiner Form der Trommel 1 angepaßt ist.To separate from the solid mixture in addition to the usually separated non-magnetic metals and the remaining Fe fractions, the balance weight is 1.1 in a unit with a transport magnet 1.2 or formed as a magnet, wherein it is adapted in its shape of the drum 1.

Zur Optimierung des Wirkungsgrades des Magnetfeldes und letztlich des Trenneffektes wird die Form des Ausgleichgewichtes 1.1 entsprechend dem zu erzeugenden Magnetfeld und technologisch günstig sichelförmig gestaltet.To optimize the efficiency of the magnetic field and ultimately the separation effect, the shape of the balance weight 1.1 is designed in accordance with the magnetic field to be generated and technologically favorable sickle-shaped.

In Kombination dazu wird der Magnetrotor 4 mit Permanentmagneten 3 bestückt, die hinsichtlich der Form, der Maße und der Polaritäten sowohl in radialer als auch axialer Richtung des Magnetrotors 4 unterschiedlich ausgeführt sein können.In combination, the magnet rotor 4 is equipped with permanent magnets 3, which can be designed differently in terms of shape, dimensions and polarities in both the radial and axial directions of the magnet rotor 4.

Allein mit einer so ausgeführten Vorrichtung wird ermöglicht, daß diese den Anforderungen des durch die Erfindung zu lösenden, eingangs dargestellten Problems entspricht.Only with a device so executed is made possible that this meets the requirements of the invention to be solved by the problem initially presented.

Wird die Trommel 2 mit dem exzentrisch angeordneten Magnetrotor 4 als Kopftrommel in einem endlosen, die Feststoffmischung zuführenden Förderbandsystem 5 mit Förderband 5.1 (Fig. 3, 4) eingeordnet und ein Trennscheitel 6 nachgeordnet, sind die jeweilige Zusammensetzung der separierten Fraktion erkennende Mittel 7, wie z.B. eine Kamera, vorgesehen, die mit einer Stellvorrichtung 9 zusammenwirken, welche den Trennscheitel 6 auf eine konzentrierte Sortenreinheit der Fraktion einstellt.If the drum 2 with the eccentrically arranged magnet rotor 4 as a head drum in an endless, the solid mixture feeding conveyor belt system 5 with conveyor belt 5.1 (Fig. 3, 4) arranged and downstream of a separating apex 6, the respective composition the separated fraction detecting means 7, such as a camera, provided, which cooperate with an adjusting device 9, which adjusts the separating vertex 6 to a concentrated purity of purity of the fraction.

Weiter unterstützend auf den Trenneffekt wirkt, daß

  • die Geschwindigkeit der Trommel und
  • die Drehzahl des Magnetrotors 4
auf den Strom der Feststoffmischung bzw. deren Zusammensetzung eingestellt und der Magnetrotor 4 sowohl im Winkel um die Drehachse der Trommel 2 als auch bezogen auf den Abstand seiner Achse zur Drehachse der Trommel 2 im Hinblick auf die zu erzeugenden Wurfparabeln der zu trennenden NE-Metalle verstellt wird.Further supporting the separation effect, that
  • the speed of the drum and
  • the rotational speed of the magnet rotor 4
adjusted to the flow of the solid mixture or their composition and the magnetic rotor 4 adjusted both at an angle about the axis of rotation of the drum 2 and with respect to the distance of its axis to the axis of rotation of the drum 2 with respect to the throwing parables of the non-ferrous metals to be separated becomes.

Bei einem Förderbandsystem 5 und Förderband 5.1 mit großer Breite ist es für bestimmte Anwendungsfälle zum Trennen von Feststoffgemischen sinnvoll, das Förderband 5.1 in zwei Bereiche durch eine umlaufende Rippe 10 aufzuteilen, diesen Bereichen je einen Trennscheitel 6.1, 6.2 nachzuordnen und diese Trennscheitel 6.1, 6.2 unabhängig voneinander so einzustellen, daß unterschiedliche Materialien von Feststoffgemischen einer Vorreinigung und einer Nachreinigung unterzogen werden können.In a conveyor belt system 5 and conveyor belt 5.1 with large width, it is useful for certain applications for separating solid mixtures to divide the conveyor belt 5.1 in two areas by a circumferential rib 10, these areas each nachnach a separating vertex 6.1, 6.2 and this separating vertex 6.1, 6.2 independently set so that different materials of solid mixtures of a pre-cleaning and a post-purification can be subjected.

Um das Förderband 5.1 auf der insbesondere breiten Trommel 2 zu führen, ohne daß das Förderband 5.1 die Lauffläche bzw. den Trommelmantel 2.1. der Trommel 2 verläßt, wird gemäß Fig. 5 eine als Wulst im Förderband 5.1 ausgestaltete Führungsrippe 11 vorgesehen, die in einer umlaufenden Nut 12 des Trommelmantels 2.1 läuft und geführt ist.In order to guide the conveyor belt 5.1 on the particular wide drum 2, without the conveyor belt 5.1, the tread or the drum shell 2.1. leaves the drum 2, 5 is provided as a bead in the conveyor belt 5.1 guide rib 11, which runs in a circumferential groove 12 of the drum shell 2.1 and is guided as shown in FIG ..

Die oberen Kanten des Trennscheitel 6, 6.1, 6.2 können zur Verbesserung der Trennqualität als nicht dargestellte rotierende Rolle ausgebildet sein.The upper edges of the separating vertex 6, 6.1, 6.2 may be formed to improve the separation quality as a rotating role, not shown.

Bei den zutreffenden Ausführungsformen der erfindungsgemäßen Vorrichtung verhindert ein Abstreifer 8 (Fig. 3) an dem äußeren Mantel 2.1 der Trommel 2 das schädliche Eintreten von Fraktionspartikeln zwischen Förderband 5.1 und Trommelmantel 2.1.In the relevant embodiments of the device according to the invention, a scraper 8 (FIG. 3) on the outer casing 2.1 of the drum 2 prevents the harmful entry of fraction particles between the conveyor belt 5.1 and the drum casing 2.1.

Für die industrielle Praxis ist es mit entscheidend, ein Verfahren bereitzustellen, welches bei einem eventuellen Spannungsausfall trotzdem die Trennqualität bis zum Stillstand des Antriebssystems sichert. Für diesen Fall sieht das erfindungsgemäße Verfahren vor, die Energie des noch rotierenden Magnetrotors 4 für den nicht dargestellten Motor zum Antrieb des Förderbandsystems 5 zu verwenden, um die Trommel 2 mindestens solange über den nun als Generator wirkenden anderen, nicht dargestellten Motor des Magnetrotors 4 zu betreiben, bis die bei Spannungsausfall noch auf dem Förderbandsystem 5 verbliebene Rest-Feststoffmischung separiert ist.For industrial practice, it is crucial to provide a method which, in the event of a power failure, nevertheless ensures the separation quality until the drive system is at a standstill. For this case, the inventive method provides to use the energy of the still rotating magnet rotor 4 for the motor, not shown, for driving the conveyor belt system 5 to the drum 2 at least as long as acting as a generator other, not shown motor of the magnet rotor 4 operate until the voltage remaining on the conveyor belt system 5 remaining residual solids mixture is separated.
