Verfahren zur Abscheidung von Eisen aus Müll.Process for separating iron from garbage.
Die Erfindung betrifft ein Verfahren zum Ausscheiden von Eisenteilen aus Müll.The invention relates to a method for separating iron parts from garbage.
Bas Ausscheiden der im Müll enthaltenen Eisenteile ist
einesteils wegen ihres Viertes erwünscht, zum andern ist
diese Maßnahme erforderlich, um evtl. für die Aufbereitung des Mülls nachgeschaltete Maschinen vor Zerstörung zu
bewahren.Bas is excretion of the iron parts contained in the garbage
on the one hand it is desirable because of its fourth, on the other hand it is desired
This measure is necessary to prevent any downstream machines for processing the waste from being destroyed
maintain.
Es ist bekannt, die Eisenteile durch Magnete, die in den Trommeln der Förderbänder angebracht sind, oder durch sogenannte iiberbandmagnete über den Förderbändern aus dem Müll abzusondern.It is known that the iron parts by magnets, which are mounted in the drums of the conveyor belts, or by so-called Separate overbelt magnets from the garbage above the conveyor belts.
Da jedoch infolge der ausserordentlich unterschiedlichen beschaffenheit des Mülls die üiisenteile teilweise stark mit
den nichteisenhaltigen Müllteilen verfilzt sind, ist es
unausbleiblich, daß mit dem Eisen viele Müllteile mitgerissen und ausgeschieden werden. Der Wert des gewonnenen
Eisenschrottes wird infolge seiner Verunreinigung sehr
vermindert.However, because of the extremely different nature of the garbage, the iron parts are partly strongly matted with the non-ferrous garbage parts, it is
it is inevitable that many pieces of waste will be carried away with the iron and eliminated. The value of the scrap iron obtained becomes great as a result of its pollution
reduced.
Man hat daher versucht, das zunächst noch verunreinigte
Eisen nochmals einer magnetischen Sortierbehandlung zu
unterziehen. Dieses Verfahren erfüllt den beabsichtigten Zweck jedoch nur unvollkommen, da die Eisentelle aus einem
relativ ruhenden Zustand und geschichteter Anordnung desAttempts have therefore been made to remove what was initially still contaminated
Iron again to a magnetic sorting treatment
undergo. However, this method only incompletely fulfills the intended purpose, since the iron parts consist of a relatively stationary state and a layered arrangement of the

Gutes von den Magneten angezogen werden, wobei das dazwischen liegende Nichteisengut wieder gegen die magnetische Fläche festgeheftet und gemeinsam mit dem Eisen ausgetragen wird.Good will be attracted by the magnets, with the non-ferrous material lying in between again against the magnetic one Stapled surface and carried out together with the iron.
Der Erfindung liegt die Aufgabe zugrunde, die Mischung von Eisenteilen und Nichteisenteilen den magnetischen Kraftlinien so darzubieten, daß die Eisenteile angezogen werden, andererseits die Nichteisenteile die Möglichkeit haben, sich von den Eisenteilen zu trennen und heraussmfallen. Biese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das von einem Magnetband abfallende noch mit unmagnetischen Teilen verunreinigte Gut an einem nahezu senkrecht aufsteigenden Magnetband vorbeigeführt wird, von dem die metallischen Bestandteile aufgefangen und so von den allein unter dem Einfluß ihrer Schwerkraft stehenden nichtmetallischen Bestandteilen getrennt werden.The invention is based on the object of the mixture of iron parts and non-iron parts to the magnetic lines of force present so that the iron parts are attracted, on the other hand, the non-ferrous parts have the opportunity to separate from the iron parts and fall out. tuck The object is achieved according to the invention in that the part falling from a magnetic tape still has non-magnetic parts contaminated goods on an almost vertically rising Magnetic tape is passed, from which the metallic components are caught and so from the alone under the Influence of their gravity standing non-metallic components are separated.
In weiterer Ausgestaltung der Erfindung kann ein in Fallrichtung der Nichteisenteile gerichteter Luftstrom, deren Abfall bezw. Trennung von den Eisenteilen begünstigen. Das nahezu senkrecht angeordnete Magnetband kann gleichzeitig dazu dienen, die auszuscheidenden Teile zu einer Sammelstelle zu fördern, wo an dem Abfall des Bandes ein weiterer Luftstrom gegebenenfalls noch verbliebene Restteile von nichtmagaetischera Gut von den Eisenieüeii trennt«In a further embodiment of the invention, an air flow directed in the direction of fall of the non-ferrous parts, their Waste or Promote separation of the iron parts. The almost vertically arranged magnetic tape can simultaneously serve to convey the parts to be separated to a collection point, where another is attached to the waste of the tape Air flow separates any remaining parts of non-magical good from the iron "
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the invention is shown in the drawing and is described in more detail below:
Über 3inest den Müll transportierenden Förderband i ist in an sich bekannter Weise ein Überbandmagnet 2 angeordnet, dessen vorbeigeführtes Förderband 3 die angezogenen. Eisenteile mit den anhaftender» Fremdkörpern etwa an. der limitnksifcl!se 4 abwirft« Di© in ihrem etwa entlang eine* p:.,:ral-rli.Bchen Bahn in aufgelockertem Zustand abfallende Eis9nfrsmä':o?perKisehungAn overband magnet 2 is arranged in a manner known per se over 3inest the trash transporting conveyor belt i, the conveyor belt 3 of which is moved past the attracted. Iron parts with the adhering »foreign bodies, for example. the limitnksifcl! se 4 throws off “Di © in its roughly along a * p:

gerät hierbei in den Kraftlinienbereich eines etwa senkrecht angeordneten Magnetbandes 5» welches die Eisenteile anzieht, während die sich infolge der Verwirbelung beim Abfall gelösten Nichteisenkörper auf das Förderband 6 fallen und von diesem abtransportiert werden. Dieser Abfallvorgang kann durch einen von dem Ventilator 7 senkrecht nach unten gerichteten Luftstrahl 8 unterstützt werden.gets into the force line area of an approximately vertically arranged magnetic tape 5 »which contains the iron parts attracts, while the non-ferrous bodies dissolved as a result of the turbulence in the waste settle on the conveyor belt 6 fall and be carried away by this. This waste process can be vertical by one of the fan 7 downward air jet 8 are supported.
Das Magnetband 5 wird zweckmässig als Fördermittel benutzt, um das ausgeschiedene Eisen auf eine höhere Ebene zu fördern, von welcher es durch einen Schacht 9 in den Sammelbehälter 10 fällt» Hierbei wird es zweckmässig noch einmal durch einen senkrecht zur Fallrichtung des Materials gerichteten Luftstrom Ii durchdrungen, welcher die Verunreinigungen in eine Beruhigungskammer 12 bläst, aus welcher sie auf das Förderband 6 gleiten. Die Blasluft wird durch die Umlenkungskiemen 13 abgeleitet.The magnetic tape 5 is expediently used as a conveying means to convey the precipitated iron to a higher level, from which it falls through a shaft 9 into the collecting container 10 »Here it is useful again penetrated by an air flow Ii directed perpendicular to the direction of fall of the material, which removes the impurities blows into a calming chamber 12, from which they slide onto the conveyor belt 6. The blown air is through the deflection gills 13 derived.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die durch die Eigenart des Mülls besonders fest an den Eisenteilen sitzenden Nichteisenteile weitgehend abgetrennt werden und dadurch der Wert des wiedergewonnenen Eisenschrottes erheblich erhöht wird.The advantages achieved by the invention are in particular that the particular nature of the garbage Non-ferrous parts firmly attached to the iron parts are largely separated off, thereby reducing the value of the recovered iron scrap is increased significantly.
