-2-* Beschreibung-2-* Description

Die Erfindung bezieht sich auf Zerkleinerer mit mehreren rotierenden schraubenförmigen Zerkleinerungselementen.
Aus dem russischen Urheberschein 596439 ist ein Zerkleinerungsprinzip mit drei Walzen bekannt. Auch in dem EP 00 81 539 wird
eine Anordnung zur Zerkleinerung von Material beschrieben, die
mit rotierenden Walzen arbeitet. Desweiteren werden Zerkleinerungsgeräte hergestellt, die nach diesem Prinzip arbeiten.
Dabei hat es sich durchgesetzt, daß zwei Oberwalzen, die eine
schraubenförmige Wendelung aufweisen, das zu zerkleinernde Material einziehen und vorzerkleinern, während die dritte, untere
Walze gegen ein Messer arbeitet und damit die endgültige Bruchgröße erzielt wird.The invention relates to shredders with several rotating helical shredding elements.
A crushing principle with three rollers is known from the Russian copyright certificate 596439. EP 00 81 539 also describes
an arrangement for crushing material is described, which
works with rotating rollers. Furthermore, shredding devices are manufactured that work according to this principle.
It has become common practice to use two upper rollers, one
helical spiral, draw in and pre-shred the material to be shredded, while the third, lower
Roller works against a knife to achieve the final fraction size.

Um ein angemessenes Verhältnis zwischen eingezogenem Material und durch die Schneidwalze zerkleinerten Materials zu erreichen, muß ein bestimmtes Drehzahlverhältnis zwischen den Oberwalzen und der Schneidwalze bestehen. Mit einer Zahnradübersetzung zwischen den Oberwalzen und der Schneidwalze ist dies nicht immer zu erreichen. In order to achieve an appropriate ratio between the material drawn in and the material shredded by the cutting roller, a certain speed ratio must exist between the upper rollers and the cutting roller. This cannot always be achieved with a gear ratio between the upper rollers and the cutting roller.

Andererseits hat es sich beim Einsatz von Zerkleinerern in Kompostierungs- und Vergärungsanlagen durchgesetzt, daß neben dem zu zerkleinernden Bioabfall bereits vorzerkleinerter Grünschnitt parallel verarbeitet werden. D. h. , daß die Aufgabe der Vorzerkleinerung durch die Oberwalzen kaum noch besteht, andererseits die zwei oder auch mehr Oberwalzen notwendig sind, um eine genügend große Einzugsöffnung zu erhalten. Da die Aufgabe der Vorzerkleinerung zurücktritt, könnte prinzipiell mehr zerkleinertes Material pro Zeiteinheit erzeugt werden, wenn dem nicht die beschränkte Durchsatzfähigkeit der unteren Schneidwalze entgegenstehen würde, die auch durch Drehzahlerhöhung nur in begrenztem Maße erhöht werden kann.On the other hand, when using shredders in composting and fermentation plants, it has become common practice to process pre-shredded green waste in parallel with the organic waste to be shredded. This means that the task of pre-shredding by the upper rollers hardly exists anymore, but on the other hand, two or more upper rollers are necessary to obtain a sufficiently large intake opening. Since the task of pre-shredding is reduced, in principle more shredded material could be produced per unit of time, if this were not opposed by the limited throughput capacity of the lower cutting roller, which can only be increased to a limited extent by increasing the speed.

Die Erfindung stellt sich deshalb die Aufgabe, einen Zerkleinerer zu schaffen, der nach oben genanntem Prinzip arbeitet, aber eine höhere Durchsatzleistung bei kleiner Bruchgröße aufweist.The invention therefore has the task of creating a shredder that works according to the above-mentioned principle, but has a higher throughput with smaller fragment size.

Erfindungsgemäß wird das dadurch erreicht, daß zwei Schneidwalzen, die beide gegen ein Messer arbeiten, allein oder unterhalb von zwei oder mehr Oberwalzen angeordnet sind.According to the invention, this is achieved in that two cutting rollers, both working against a knife, are arranged alone or below two or more upper rollers.

Anhand der Zeichnung wird eine Ausführungsform der Erfindung näher erläutert. Die Zeichnung zeigt einen Schnitt durch die erfindungsgemäße Zerkleinerungseinheit.An embodiment of the invention is explained in more detail with reference to the drawing. The drawing shows a section through the shredding unit according to the invention.

In dem Zerkleinerergehäuse 1 sind die beiden Oberwalzen 2 und die beiden Schneidwalzen 3 jeweils an den Stirnseiten drehbar gelagert angeordnet. An den Schneidwalzen 3 sind fest im Zerkleinerergehäuse 1 angeordnet die Schneidmesser 4 angestellt.
Das zu zerkleinernde Material wird von oben in den Zerkleinerer gegeben, von den beiden Oberwalzen 2 erfaßt und in den Raum 5 zwischen den Oberwalzen 2 und den Schneidwalzen 3 transportiert. Aus dem Raum 5 wird das Material mit den Wendelungen der Schneidwalzen 3 erfaßt und jeweils nach außen transportiert. Das Material, das die Schneidwendeln der Schneidwalzen 3 herausragt, wird an den beiden Schneidmessern 4 abgeschnitten. Das so zerkleinerte Material wird nach unten aus dem Zerkleinerergehäuse 1 ausgetragen. In the shredder housing 1, the two upper rollers 2 and the two cutting rollers 3 are each arranged on the front sides so that they can rotate. The cutting blades 4 are fixedly arranged in the shredder housing 1 and are set on the cutting rollers 3.
The material to be shredded is fed into the shredder from above, grasped by the two upper rollers 2 and transported into the space 5 between the upper rollers 2 and the cutting rollers 3. The material is grasped from the space 5 by the spirals of the cutting rollers 3 and transported outwards. The material that protrudes from the cutting spirals of the cutting rollers 3 is cut off by the two cutting blades 4. The material shredded in this way is discharged downwards from the shredder housing 1.

Das Drehzahlverhältnis zwischen den Oberwalzen 2 und den Schneidwalzen 3 wird in Abhängigkeit von der Materialbeschaffenheit festgelegt. Auch die Konfiguration der Wendelung der Oberwalzen 2 und der Schneidwalzen 3 wird in Abhängigkeit vom zu zerkleinernden Material gewählt. Prinzipiell ist auch eine Schneidmesseranordnung zwischen den Schneidwalzen 3 denkbar.The speed ratio between the top rollers 2 and the cutting rollers 3 is determined depending on the material properties. The configuration of the spiral of the top rollers 2 and the cutting rollers 3 is also selected depending on the material to be shredded. In principle, a cutting blade arrangement between the cutting rollers 3 is also conceivable.
