Description
Verfahren und Vorrichtung zur Verarbeitung von Feinschrott Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verarbeiten von fein- bzw. kleinstückigem Schrott.Method and device for processing fine scrap The invention relates to a method and a device for processing fine or small pieces Scrap metal.
Um feinstückigen, insbesondere sperrigen Schrott in wirtschaftlicher Weise für einen neuen Schmelzprozeß wiederzugewinnen, ist es üblich, den Schrott bestimmten Behandlungen zu unterwerfen und zu kompakten Körpern zu pressen. Dabei wird der lose Schrott mittels Pressen meist zu quaderförmigen Körpern zusammengepreßt.To get fine-piece, especially bulky scrap in economic Way for a new smelting process to reclaim, it is customary to reclaim the scrap subject to certain treatments and pressed into compact bodies. Included the loose scrap is usually compressed into cuboid bodies by means of pressing.
Dieses Verfahren ist jedoch in mancher Hinsicht unzureichend, weil es auf diese Weise nicht möglich ist, die Schrottstücke auf kleinsten Raum zusammen-2 ressen und auch von Unreinigkeiten zu befreien, ep beispielsweise von dem Inhalt von Konservendosen herrühren können. Auch ist es erwünscht, daß die zusammengepreßten Schrottballen möglichst homogen sind und keine Fremdkörper, wie beispielsweite Teile von Gummireifen, Papier, Karton u, dgl., enthalten. Da diese Ballen meist sehr groß sind, ist es schwierig, solche Fremdkörper in einem Ballen festzustellen.However, this method is inadequate in some respects because In this way it is not possible to put the scrap pieces together in the smallest space-2 ressen and also to free it from impurities, for example from the content can come from food cans. It is also desirable that the compressed Scrap bales are as homogeneous as possible and no foreign bodies, such as large parts of rubber tires, paper, cardboard and the like., Contained. Because these bales are usually very large it is difficult to detect such foreign objects in a bale.
Der Erfindung liegt daher die Aufgabe zugrunde, Feinschrott so aufzuarbeiten, daß er keine Abfälle und Fremdkörper mehr enthält, sogar von eventuell vorhandenem Rost befreit wird und in Form von verhältnismäßig kleinen Kugeln großer Dichte anfällt. The invention is therefore based on the object of processing fine scrap in such a way that it no longer contains any waste or foreign bodies, is even freed from any rust that may be present and arises in the form of relatively small balls of high density .
Dies wird erfindungsgemäß dadurch erreicht, daß der Schrott durch eine Stoß- oder Schlagbehandlung zerkleinert und durch Pressen zu Körpern kleiner Abmessungen geformt wird.This is achieved according to the invention in that the scrap through crushed by a shock or impact treatment and made smaller by pressing them into bodies Dimensions is molded.
Dieses Verfahren wird gemäß der Erfindung mit einer Vorrichtung durchgeführt, die aus einem Brechwerk besteht, das einen von einem Gitterrost begrenzten Behälter und einen Beschickungstrichter aufweist, sowie einen Rotor, der mit mehreren Reihen von im Abstand voneinander angeordneten, mit Vorsprüngen versehenen Hämmern und kreisscheibenförmigen Reibrollen ausgerüstet ist, wobei die Hämmer und die Reibrollen auf dem Umfang eines beliebigen Rotorkreises abwechselnd angeordnet sind.This method is carried out according to the invention with a device which consists of a crusher that has a container bounded by a grating and a feed hopper, and a rotor having multiple rows of spaced apart, protruded hammers and circular disc-shaped friction rollers, the hammers and the friction rollers are arranged alternately on the circumference of any rotor circle.
Vorteilhafterweise verhält sich die Zahl der Reibrollen zu der Zahl der Hämmer etwa wie 2: 5. Weitere vorteilhaften Merkmale sind in der nachfolgenden Beschreibung eines in schematischer Weise in der Zeichnung dargestellten Ausführungsbeispieles angegeben. Es zeigt F i g. 1 einen Achsenlängsschnitt durch das erfindungsgemäße Brechwerk und F i g. 2 einen senkrechten Achsenschnitt nach der Schnittlinie II-II der F i g. 1. Die Vorrichtung besteht aus einem Brechwerk, das in einem Käfig 1 angeordnet ist, der an seiner Unterseite durch einen Gitterrost 2 begrenzt wird und an seiner oberen Seite einen Beschickungstrichter 3 aufweist. Der Rotor des Brechwerkes besteht aus einer Welle 4, auf der eine Mehrzahl von kreisscheibenförmigen Querträgern 5 aufgekeilt ist. Diese Querträger 5 weisen je vier Löcher auf, deren jedes eine Achse 6 aufnimmt, die sich parallel zu der Welle 4 erstreckt und die die Querträger 5 miteinander verbindet.The ratio of the number of friction rollers to the number of hammers is approximately 2: 5. Further advantageous features are given in the following description of an embodiment example shown schematically in the drawing. It shows F i g. 1 shows an axial longitudinal section through the crusher according to the invention and FIG. 2 shows a vertical axial section along the section line II-II in FIG. 1. The device consists of a crusher which is arranged in a cage 1 which is delimited on its underside by a grating 2 and has a feed hopper 3 on its upper side. The rotor of the crusher consists of a shaft 4 on which a plurality of circular disk-shaped cross members 5 are keyed. These cross members 5 each have four holes, each of which receives an axis 6 which extends parallel to the shaft 4 and which connects the cross members 5 to one another.
Auf jeder dieser Achsen 6 sind frei drehbar Hämmer 7 und kreisscheibenförmige Reibrollen 8 gelagert, die in einem Abstand voneinander gelagert sind, der demjenigen zweier Querträger 5 entspricht.On each of these axes 6 hammers 7 and circular disk-shaped are freely rotatable Friction rollers 8 mounted, which are mounted at a distance from each other, the one two cross members 5 corresponds.
Der Rotor wird von einem nicht gezeichneten Motor mittels eines Treibriemens 9 und einer Riemenscheibe 10 angetrieben, die auf der Welle 4 aufgekeilt ist, die sich zwischen den Lagern 11 erstreckt und ein Schwungrad 12 trägt.The rotor is driven by a motor (not shown) by means of a drive belt 9 and a pulley 10 driven, which is keyed on the shaft 4, the extends between the bearings 11 and carries a flywheel 12.
Der zu verarbeitende Schrott wird dem Brechwerk durch den Beschickungstrichter 3 zugeführt und wird durch die Hämmer 7 zerkleinert. Da aber die Abstände zwischen den einzelnen Hämmern verhältnismäßig beträchtlich sind, ist die Zerkleinerung des Schrottes keine so weitgehende wie bei den üblichen Brechwerken.The scrap to be processed is fed to the crusher through the feed hopper 3 and is crushed by the hammers 7. But since the distances between the individual hammers are relatively considerable, the crushing of the Scrap not as extensive as in the usual crushing mills.
Diese Zerkleinerung reicht nicht aus, um die Schrottstücke durch den Gitterrost 2 hindurchfallen zu lassen, und so verbleiben diese Schrottstücke in dem Brechwerk, wo sie von den Reibrollen 8 in einem solchen Maße zusammengedrückt werden; daß sie durch den Gitterrost 2 hindurchfallen können.This shredding is not enough to get the scrap pieces through the Let grate 2 fall through, and so these pieces of scrap remain in the crusher, where they are driven by the friction rollers 8 in one such measure be squeezed; that they can fall through the grating 2.
Da der in das Bre2hwerk eingebrachte Schrott dauernden Stößen und Schlägen ausgesetzt ist, werden die Schrottstücke vollständig voneinander und von ihnen anhaftenden Abfällen getrennt. Die Reibung, die die Schrottstücke an dem Gitterrost 2 und auch an den Hämmern und- -den Reibrollen erfahren, bewirkt darüber hinaus, daß die Schrottstücke .etwa bedeckender Rost von diesen abgelöst wird. An der Entleerungsstelle des Brechwerkes erhält man auf diese Weise einerseits den Schrott selbst und andererseits ein Staubgemenge von Abfällen und Rost. Um die Trennung zu vervollständigen, genügt es, unterhalb des Gitterrostes 2 entweder eine Siebtrommel oder 'einen Drahtkorb;anzubrdnen. -Das Verhältnis der Zahl der Reibrollen zu der Zahl der Hämmer wird vorteilhafterweise ungefähr wie 2: 5 gewählt, und der in einem solchen Brechwerk bearbeitete Schrott fällt in der Form von äußerst dichten und mit keinerlei Fremdkörpern verunreinigten Kugeln an.-Man hat feststellen können, daß Konservendosen kleiner Abmessungen praktisch nicht zerkleinert, sondern nur sehr stark zusammengepreßt wurden, während: Kannen, Kanister und Behälter größerer Abmessungen in Stücke zerkleinert wurden, die etwa dieselbe Menge Metall aufweisen wie kleine Konservendosen, so daß auf diese Weise bezüglich ihrer Abmessungen ziemlich homogene Körper als Endprodukte erhalten werden. ._ Aus dem Vorstehenden - ergibt sich, daß der so behandelte Schrott alle erforderlichen Eigenschaften aufweist, um, ohne irgendwelche Nachteile in Kauf nehmen zu müssen, in metallurgischen Verfahren weiterverarbeitet werden zu können, da er insbesondere keinerlei Verunreinigungen mehr . enthält. Ein weiterer Vorteil ist, daß der so behandelte Sclrdtt in loser Form anfällt;-so..-daß seine Zusammensetzung ohne weiteres erkennbar ist, und daß das Beladen .von Transportbehältern-und- das Beschicken von Schmelzöfen unter wesentlich günstigeren Bedingungen effolgen kann, als sie seither bestanden, was insbesondere darauf zurückzuführen ist, daß der so behandelte Schrott Körper von nur sehr kleinen Abmessungen darstellt.Since the scrap brought into the mashing unit is subject to constant impacts and Exposed to impacts, the scrap pieces are completely separated from each other and from waste adhering to them separated. The friction that the scrap pieces have on the grating 2 and also experienced with the hammers and -the friction rollers, also has the effect of that the pieces of scrap .about covering rust is detached from them. At the emptying point of the crusher you get in this way on the one hand the scrap itself and on the other hand a lot of dust from rubbish and rust. To complete the separation is enough it, below the grating 2 either a sieve drum or a wire basket; to be burned. -The ratio of the number of friction rollers to the number of hammers becomes advantageous chosen roughly like 2: 5, and the scrap processed in such a crusher falls in the form of extremely dense and not contaminated with any foreign bodies Balls on.-It has been found that small cans are practical not crushed, but only very strongly compressed, while: pitchers, Canisters and containers of larger dimensions were crushed into pieces that were roughly contain the same amount of metal as small tin cans, so in this way bodies which are fairly homogeneous in terms of their dimensions can be obtained as end products. ._ From the foregoing - it follows that the scrap treated in this way has all the necessary Has properties in order to, without having to accept any disadvantages, to be able to be further processed in metallurgical processes, since he in particular no more impurities. contains. Another advantage is that it does treated scrap is obtained in loose form; -so ...- that its composition is readily available can be seen, and that the loading .of transport containers-and- the loading of Melting furnaces can operate under much more favorable conditions than they have since then passed, which is due in particular to the fact that the scrap treated in this way Represents bodies of only very small dimensions.
