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 vorzugsweice 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, which 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. Further separation takes place at a subsequent magnetic separator instead of. The scrap obtained in this way has an iron content of 75 to a maximum of 80%. It is preferably delivered 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 considered by the steelworks to be too low for economic utilization. This scrap also has a relatively high content of non-ferrous metals such as tin or copper.

Weiterhin ist aus der FR-A-2 376 703 eine rotierende Siebtrommel zum Sortieren durch differentielle Zerkleinerung und Klassifizierung von Verpackungsmaterial aus Glas und Kunststoff bekannt. Die Siebtrommel besitzt einen mittleren Abschnitt aus perforiertem Blech, der mit Längshebern versehen ist. Die spezielle Ausbildung dieser Siebtrommel dient der Zerschlagung der spröden Glasverpackungen, wobei die Längsheber so angeordnet sind, daß herunterfallende Glasstücke direkt auf die Vorderkante dieser Längsheber auftreffen und hierdurch zerbrechen. Die zerkleinerten Glasstücke werden durch die Öffnungen im Trommelmantel ausgetragen, während die unzerkleinerten Kunststoffteile am Trommelende ausgegeben werden.Furthermore, from FR-A-2 376 703 a rotating sieve drum for sorting by differential comminution and classification of packaging material made of glass and plastic is known. The sieve drum has a central section made of perforated sheet metal, which is provided with longitudinal lifters. The special design of this sieve drum serves to break up the brittle glass packaging, the longitudinal lifters being arranged in such a way that falling pieces of glass hit the front edge of these longitudinal lifters directly and break them as a result. The shredded pieces of glass are discharged through the openings in the drum shell, while the uncrushed plastic parts are discharged at the end of the drum.

Es ist daher die Aufgabe der vorliegenden Erfindung, die bekannte Vorrichtung zur Säuberung von in verbranntem Haushaltsmüll enthaltenem eisenhaltigem Schrott mit einer drehbaren Siebtrommel und mindestens einem Magnetscheider in der Weise zu verbessern, daß diese wesentlich vereinfacht wird und trotzdem ein hoher Eisengehalt sowie ein geringer Gehalt an Nichteisenmetallen im aufbereiteten Schrott erhalten werden. Dieser soll außerdem verpreßbar sein.It is therefore the object of the present invention to improve the known device for cleaning iron-containing scrap contained in burned household waste with a rotatable sieve drum and at least one magnetic separator in such a way that it is considerably simplified and nevertheless has a high iron content and a low content of Non-ferrous metals can be obtained in the processed scrap. 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, wobei die Mitnehmerelemente in Längsrichtung der Siebtrommel unterteilt und unterschiedlich ausgebildet sind, derart, daß die Mitnehmerelemente auf der Schrotteingabeseite eine größere Menge Schrott nach oben tragen als diejenigen auf der Schrottausgabeseite, erfolgt im der Schrotteingabeseite benachbarten Teil der Siebtrommel zunächst durch Schlagwirkung ein Abplatzen von an den eisenhaltigen Bestandteilen klebenden Asche- und Schlacketeilchen sowie auch von anhaftendem Eisenoxid (Rost, Zunder), wobei auch größere Schlackestücke zerschlagen werden, so daß sie durch die Sieböffnungen der Trommel austreten können, und im der Schrottausgabeseite benachbarten Teil der Siebtrommel wird der Schrott im wesentlichen nur umgewälzt, so daß hier die noch anhaftenden feinen Verunreinigungen abgerieben werden.Characterized in 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, the driver elements being subdivided and designed differently in the longitudinal direction of the sieve drum, such that the driver elements on the scrap input side carry a larger amount of scrap upwards than those on the scrap output side, in the part of the sieve drum adjacent to the scrap input side, flaking of ash and slag particles adhering to the iron-containing constituents and also adhering iron oxide (rust , Scale), with larger pieces of slag being broken up so that they can escape through the sieve openings of the drum, and in the part of the sieve drum adjacent to the scrap discharge side, the scrap is essentially only circulated, so that here the still adhering fine impurities can be rubbed off.

Mit der erfindungsgemäßen Vorrichtung lassen sich Eisengehalte im Schrott von mindestens 90 % 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% can be achieved. There is tinned or coated with another non-ferrous metal, especially in household waste Iron. 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 with the formation of rust or scale, and when it hits the drum base, the rust or scale flakes off with the non-ferrous metal layer lying above it.

The invention is explained in more detail below with reference to exemplary embodiments shown in the figures. Show it:

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 a 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 screen drum 3 is inclined somewhat downwards from the scrap input side to the other end face, so that the scrap migrates through the screen 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 Schlackenstücke werden zerschlagen. Diese Wirkung wird verstärkt, 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 increased if the sieve 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 screening 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 upwards, 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 sieve 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 vibration conveyor 9 and throws them onto a conveyor belt 11. The scrap removed from this 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 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 relative 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 carriers 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 faster 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.
