Abstract

The invention describes a device for the treatment of ferrous scrap contained in incinerated household waste, the said device being equipped with a rotatable screening drum (3) and at least one magnetic separator. Attached to the cylindrical inner wall of the screening drum are vanes (5, 6) acting in such a way that, when the screening drum is rotated, the scrap is carried upwards and then falls freely onto the bottom of the drum. This detaches ash and slag particles sticking to the pieces of iron as well as rust and scale, and relatively large pieces of slag are broken up. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Verbrannter Haushaltsmüll, der durch einen Magnetscheider vorsortiert wurde, weist einen Eisengehalt in Form von reinem Eisen sowie Eisenoxid (Zunder, Rost) von etwa 40 bis 60 % auf. Die restlichen Bestandteile sind im wesentlichen Asche und Schlacke. Um den Eisen­gehalt zu erhöhen, d.h. die eisenhaltigen Bestandteile von den übrigen Bestandteilen zu separieren, wird dieses Gemisch durch eine geneigte rotierende Siebtrommel geführt, in der es umgewälzt wird. Dabei passieren Asche- und Schlacketeilchen die Öffnungen in der Wandung der Siebtrommel, während die größeren eisen­haltigen Bestandteile an der tieferen Stirn­seite der Siebtrommel auf eine Fördervor­richtung ausgegeben werden. An einem nachfolgenden Magnetscheider findet eine weitere Separierung statt. Der so erhaltene Schrott weist einen Eisengehalt von 75 bis maximal 80 % auf. Er wird vorzugsweise in loser Form mit einem Schüttgewicht von etwa 250 bis 300 kg an Stahl­werke oder zur weiteren Aufbereitung an Shredderbetriebe (Zerdirator) abgegeben. Dieser Schrott ist nicht preßbar.Burned household waste that has been pre-sorted by a magnetic separator has an iron content in the form of pure iron and iron oxide (scale, rust) of around 40 to 60%. The remaining components are mainly ash and slag. In order to increase the iron content, ie to separate the iron-containing components from the other components, this mixture is passed through an inclined rotating sieve drum in which it is circulated. Ash and slag particles pass through the openings in the wall of the sieve drum, while the larger ferrous components are discharged onto a conveyor at the lower end of the sieve drum. On a subsequent one Magnetic separators undergo further separation. The scrap obtained in this way has an iron content of 75 to a maximum of 80%. It is preferably released in bulk with a bulk density of around 250 to 300 kg to steelworks or for further processing to shredder companies (director). This scrap cannot be pressed.

Der auf die vorbeschriebene Weise erhaltene Eisengehalt des Schrottes wird von den Stahl­werken jedoch zunehmend für eine wirtschaft­liche Verwertung als zu niedrig angesehen. Auch besitzt dieser Schrott einen relativ hohen Gehalt an Nichteisenmetallen wie Zinn oder Kupfer.The iron content of the scrap obtained in the manner described above is increasingly regarded by the steelworks as being too low for economic utilization. This scrap also has a relatively high content of non-ferrous metals such as tin or copper.

Es ist daher die Aufgabe der vorliegenden Er­findung, die bekannte Vorrichtung zur Aufbe­reitung von in verbranntem Haushaltsmüll ent­haltenem eisenhaltigem Schrott mit einer dreh­baren Siebtrommel und mindestens einem Magnet­scheider in der Weise zu verbessern, daß ein erhöhter Eisengehalt sowie ein verringerter Gehalt an Nichteisenmetallen im aufbereiteten Schrott erhalten wird. Dieser soll außerdem verpreßbar sein.It is therefore the object of the present invention to improve the known device for processing ferrous scrap contained in burned household waste with a rotatable sieve drum and at least one magnetic separator in such a way that an increased iron content and a reduced non-ferrous metal content in the processed scrap is obtained . This should also be compressible.

Diese Aufgabe wird erfindungsgemäß gelöst durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.This object is achieved by the features specified in the characterizing part of claim 1.

Vorteilhafte Weiterbildungen der erfindungsge­mäßen Vorrichtung ergeben sich aus den Unter­ansprüchen.Advantageous developments of the device according to the invention result from the subclaims.

Dadurch, daß an der zylindrischen Innenwand der Siebtrommel Mitnehmerelemente angebracht sind, derart, daß der Schrott bei Drehung der Siebtrommel nach oben getragen wird und an­schließend durch freien Fall auf deren Boden aufschlägt, lösen sich an den eisenhaltigen Bestandteilen klebende Asche- und Schlacke­teilchen sowie auch anhaftendes Eisenoxid (Rost, Zunder) und es werden auch größere Schlackestücke, die noch nicht die Öffnungen in der zylindrischen Wand der Siebtrommel passieren können, zerschlagen, so daß sie durch diese Wand aus der Trommel austreten können. Vorzugsweise ist die zylindrische Innenwand der Siebtrommel auf der Schrotteingabeseite in einem in Längsrichtung der Siebtrommel von den Mitnehmerelementen überdeckten Bereich geschlossen. Die Teile des zu trennenden Gemisches schlagen somit auf eine geschlossene und nicht auf eine gelochte Fläche auf. Die Schlagwirkung wird hierdurch erhöht, d.h. an den eisenhaltigen Teilen anbackende Asche- und Schlacketeilchen sowie anhaftendes Eisen­oxid lösen sich noch schneller und solche Teilchen werden auch gründlicher zerschlagen.Due to the fact that driver elements are attached to the cylindrical inner wall of the sieve drum, such that the scrap is carried upward when the sieve drum rotates and then hits the floor by free fall, detachable ash and slag particles as well as adhering particles loosen on the ferrous components Iron oxide (rust, scale) and larger pieces of slag, which cannot yet pass through the openings in the cylindrical wall of the screening drum, are broken up, so that they can exit the drum through this wall. The cylindrical inner wall of the screen drum on the scrap input side is preferably closed in an area covered by the driver elements in the longitudinal direction of the screen drum. The parts of the mixture to be separated thus hit a closed and not a perforated surface. This increases the impact, i.e. Ash and slag particles that adhere to the iron-containing parts and adhering iron oxide dissolve even faster and such particles are also broken up more thoroughly.

Mit der erfindungsgemäßen Vorrichtung lassen sich lediglich durch die Neugestaltung der Siebtrommel Eisengehalte im Schrott von mindestens 90 %, d.h. eine Steigerung um mehr als 10 bis 15 % erzielen. Insbesondere im Haus­haltsmüll befindet sich verzinntes oder mit einem anderen Nichteisenmetall überzogenes Eisen. Diese Nichteisenmetalle sind für die Weiterverarbeitung des Schrottes hinderlich.With the device according to the invention, iron contents in the scrap of at least 90%, ie an increase of more than 10 to 15%, can only be achieved by redesigning the sieve drum. Iron, in particular, is found in the household waste, either tinned or coated with another non-ferrous metal. These non-ferrous metals are a hindrance to the processing of the scrap.

Es hat sich gezeigt, daß mit dem erfindungsgemäßen Verfahren auch der Gehalt der Nichteisenmetalle im Schrott verringert wird. Dies beruht auf dem Umstand, daß das Eisen unterhalb der Überzugsschicht aus dem Nichteisenmetall unter Rost- oder Zunderbildung oxidiert und beim Aufschlagen auf dem Trommelboden der Rost bzw. Zunder mit der darüberliegenden Nichteisenmetallschicht abplatzt.It has been shown that the process according to the invention also reduces the content of non-ferrous metals in the scrap. This is due to the fact that the iron below the non-ferrous metal coating layer oxidizes to form rust or scale, and when it hits the drum base, the rust or scale flakes off with the non-ferrous metal layer above it.

Die Erfindung wird im folgenden anhand von in den Figuren dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 eine Anlage zur Schrottaufbereitung,
  • Fig. 2 einen senkrechten Längsschnitt durch die in der Anlage nach Fig. 1 verwendete Siebtrommel, und
  • Fig. 3 einen senkrechten Längsschnitt durch eine in anderer Weise ausgebildete Siebtrommel.
The invention is explained in more detail below with reference to exemplary embodiments shown in the figures. Show it:
  • 1 is a plant for scrap processing,
  • Fig. 2 is a vertical longitudinal section through the screen drum used in the system of FIG. 1, and
  • Fig. 3 shows a vertical longitudinal section through a sieve drum formed in a different way.

Der aus einer Müllverbrennungsanlage kommende und durch einen Magnetscheider vorsortierte, stark mit Asche und Schlacke durchsetzte und auch einen erheblichen Anteil an Eisenoxid besitzende Schrott wird in einen Trichter 1 eingegeben und gelangt über eine Rutsche 2 durch eine stirnseitige Öffnung in eine Siebtrommel 3. Die Siebtrommel 3 ist auf zwei ringförmigen Laufflächen 4 drehbar gelagert und wird in bekannter Weise durch einen Motor relativ langsam gedreht.The scrap coming from a waste incineration plant and pre-sorted by a magnetic separator, heavily permeated with ash and slag and also having a considerable proportion of iron oxide is fed into a funnel 1 and passes through a chute 2 through a front opening into a screening drum 3. The screening drum 3 is rotatably mounted on two annular treads 4 and is rotated relatively slowly in a known manner by a motor.

An der zylindrischen Innenfläche der Siebtrommel 3 sind beispielsweise drei gleichmäßig über den Umfang verteilte platten- oder schaufel­förmige Mitnehmer 5 angebracht, die sich auf der Schrotteingabeseite über einen Teil der Siebtrommel 3 in deren Längsrichtung erstrecken.On the cylindrical inner surface of the screen drum 3, for example, three are evenly over the circumferential distributed plate or scoop-shaped driver 5 attached, which extend on the scrap input side over part of the screening drum 3 in the longitudinal direction.

Die Siebtrommel 3 ist von der Schrotteingabe­seite aus zur anderen Stirnseite hin etwas abwärts geneigt, so daß der Schrott bei der Drehung der Siebtrommel durch diese hindurch wandert und durch eine Öffnung in der anderen Stirnseite aus ihr heraustritt.The sieve drum 3 is inclined somewhat downwards from the scrap input side to the other end face, so that the scrap migrates through the sieve drum when it rotates and emerges from it through an opening in the other end face.

Bei der Drehung der Siebtrommel 3 wird der in diese eingebrachte Schrott von den Mitnehmern 5 erfaßt und nach oben getragen. Wenn ein Mit­nehmer 5 eine obere Position erreicht hat, rutscht der Schrott von diesem herunter und schlägt nach freiem Fall auf dem Trommelboden auf. Hierbei platzt an den eisenhaltigen Teilen haftende Asche, Schlacke, Rost oder Zunder von diesen ab und größere Schlackstücke werden zerschlagen. Diese Wirkung wird verstärt, wenn die Siebtrommel 3 in diesem Bereich, d.h. dem in Längsrichtung von den Mitnehmern 5 überdeckten Bereich, keine Löcher aufweist, sondern eine geschlossene zylindrische Innen­fläche besitzt. Der Schrott wird auf diese Weise optimal von den an ihm anbackenden Ver­unreinigungen gesäubert.When the sieve drum 3 rotates, the scrap brought into it is gripped by the drivers 5 and carried upwards. When a driver 5 has reached an upper position, the scrap slides down from it and hits the drum base in free fall. As a result, ash, slag, rust or scale sticking to the iron-containing parts burst off and larger pieces of slag are broken up. This effect is enhanced if the screening drum 3 in this area, i.e. the area covered in the longitudinal direction by the drivers 5 has no holes, but has a closed cylindrical inner surface. In this way, the scrap is optimally cleaned of the impurities caking on it.

Im hinteren Teil der Siebtrommel 3, d.h. auf der Schrottausgabeseite, sind weitere Mitnehmer 6 in in Umfangsrichtung gleichmäßigen Abständen an der zylindrischen Innenwand angebracht, wobei diese, wie in Fig. 2 gezeigt, gegenüber den Mitnehmern 5 versetzt sein können, und in gleicher Anzahl wie diese oder auch in unter­schiedlicher Anzahl vorhanden sein können. Die Mitnehmer 6 sind in radialer Richtung kürzer ausgebildet als die Mitnehmer 5, so daß sie den Schrott nicht nach oben transportieren, sondern im wesentlichen nur umwälzen, wobei die abgeschlagenen und zerkleinerten Verun­reinigungen durch die Öffnungen 7 im zylindrischen Teil der Siebtrommel 3 nach außen treten und auf ein umlaufendes Förderband 8 fallen.In the rear part of the screen drum 3, ie on the scrap discharge side, further drivers 6 are attached to the cylindrical inner wall at regular intervals in the circumferential direction, whereby these, as shown in FIG. 2, can be offset with respect to the carriers 5, and can be present in the same number as these or in different numbers. The drivers 6 are shorter in the radial direction than the drivers 5, so that they do not transport the scrap upward, but essentially only circulate, the cut and crushed impurities coming out through the openings 7 in the cylindrical part of the sieve drum 3 and fall on a rotating conveyor belt 8.

Der gereinigte Schrott tritt auf der rechten Stirnseite der Siebtrommel 3 aus dieser aus und fällt auf einen Vibrationsförderer 9, der ihn zu einer Magnettrommel 10 transportiert. Diese nimmt die eisenhaltigen Teile vom Vibrationsförderer 9 ab und wirft sie auf ein Förderband 11. Der von diesem abgenommene Schrott mit einem Eisengehalt von mindestens 90 % kann jetzt zu umschlagfähigen Paketen verpreßt und einer anderen geeigneten Ver­wendung (Zerdirator oder in loser Form zur Stahlherstellung) zugeführt werden.The cleaned scrap exits the drum 3 on the right end face and falls onto a vibration conveyor 9, which transports it to a magnetic drum 10. This removes the iron-containing parts from the vibratory conveyor 9 and throws them onto a conveyor belt 11. The scrap removed from it with an iron content of at least 90% can now be pressed into turnable packages and used for another suitable use (Zerdirator or in loose form for steel production) will.

Die von der Magnettrommel 10 nicht erfaßten Teile, beispielsweise größere Stücke aus Schlacke oder nicht Eisenmetallen, fallen auf ein Förderband 12 und werden von diesem heraus­getragen.The parts which are not covered by the magnetic drum 10, for example larger pieces of slag or non-ferrous metals, fall onto a conveyor belt 12 and are carried out by this.

Das Förderband 8 transportiert die ausgesiebten Verunreinigungen unter einem umlaufenden Magnet­band 13 hindurch zu einem Förderband 14, durch das diese ebenfalls herausbefördert werden. Das Magnetband 13 erfaßt mit den Verunreinigungen ausgesiebte Eisenkleinteile und wirft diese auf ein Förderband 15.The conveyor belt 8 transports the screened impurities under a rotating magnetic belt 13 to a conveyor belt 14 that these are also transported out. The magnetic tape 13 detects small iron parts screened out with the impurities and throws them onto a conveyor belt 15.

Die Siebtrommel 16 nach Fig. 3 ist in Längsrichtung in drei Abschnitte unterteilt, wobei die beiden vorderen Abschnitte so ausgebildet sind wie die beiden Abschnitte der Siebtrommel 3. Der hintere Abschnitt weist Mitnehmer 17 auf, die gegenüber der Trommelachse derart geneigt sind, daß sie bei Drehung der Siebtrommel 16 auf der sich nach oben bewegenden Seite zur Ausgabeöffnung hin nach unten verlaufen. Die Mitnehmer 17 sind zudem in einer solchen Anzahl vorgesehen, daß keine größeren Schrottansammlungen am Boden der Trommel im Bereich ihrer Ausgabeöffnung auftreten. Die Anzahl der Mitnehmer 17 ist daher vorzugsweise größer als die der Mitnehmer 5 oder 6. Durch die Neigung der Mitnehmer 17 nach unten wird der Schrott zudem schneller zur Ausgabeöffnung hin befördert, wodurch das Entstehen von Schrottansammlungen ebenfalls unterbunden wird. Die Mitnehmer 17 sorgen somit für einen gleichmäßigen Schrott­austrag. Dieser kann für eine nachfolgende automatische Weiterverarbeitung, beispielsweise das Verpressen von Paketen, ein wesentliches Erfordernis sein.3 is divided into three sections in the longitudinal direction, the two front sections being formed like the two sections of the screening drum 3. The rear section has drivers 17 which are inclined with respect to the drum axis in such a way that they are at Rotation of the screen drum 16 on the side moving upward toward the dispensing opening is downward. The drivers 17 are also provided in such a number that no large accumulations of scrap occur at the bottom of the drum in the region of their discharge opening. The number of carriers 17 is therefore preferably greater than that of carriers 5 or 6. The inclination of carriers 17 downwards also means that the scrap is conveyed more quickly to the discharge opening, which also prevents the accumulation of scrap. The driver 17 thus ensure a uniform scrap discharge. This can be an essential requirement for subsequent automatic further processing, for example the pressing of packages.
