Description

Zerkleinerungsvorrichtung Shredding device
Die Erfindung betrifft eine Zerkleinerungsvorrichtung, insbesondere für Abfallmaterial, mit einem Antrieb, mit einem eine Einfüllöffnung aufweisenden Gehäuse, und mit einer sich drehenden, umfangseitige Schneidelemente aufweisenden Zerkleinerungswalze, die mit einem Gegen¬ schneidwerkzeug zusammenwirkt.The invention relates to a comminution device, in particular for waste material, with a drive, with a housing having a filling opening, and with a comminuting roller which rotates and has circumferential cutting elements and which interacts with a counter-cutting tool.

Eine derartige Zerkleinerungsvorrichtung, bei der das Gegenschneidwerkzeug ein stationäres Gegenmesser ist, ist beispielsweise aus der DE-U 91 09 063 bekannt. Um zu verhindern, daß sich die Zwischenräume zwischen den 15 Schneidelementen mit Material füllen, ist eine Räumspa¬ tel vorgesehen, die mit dem Walzenantrieb gekoppelt fortlaufend jeweils in einen Zwischenraum eingreift und ihn ausräumt.Such a shredding device, in which the counter-cutting tool is a stationary counter knife, is known for example from DE-U 91 09 063. In order to prevent the spaces between the 15 cutting elements from filling with material, a clearing spatula is provided which, coupled to the roller drive, engages and clears an intermediate space continuously.
Z0~ Zerkleinerungsvorrichtungen, bei denen auch das Gegen¬ schneidwerkzeug durch eine Zerkleinerungwalze gebildet ist, sind ebenfalls bereits bekannt. Die Zerkleine¬ rungswalzen können aus mit Reißzähnen bestückten Zer¬ kleinerungsscheiben gebildet sein, die auf Antriebswel-Shredding devices in which the counter-cutting tool is also formed by a shredding roller are also already known. The shredding rollers can be formed from shredding disks equipped with fangs, which are driven by drive shafts.
25 len mit Abstand zueinander aufgereiht sind. Es können aber auch einstückige Zerkleinerungswalzen eingesetzt werden, an denen axial beabstandet Schneidelemente oder Zähne vorgesehen sind. Beispiele für beide Ausführungen sind der AT-B 350 988 zu entnehmen. 025 lines are lined up at a distance from each other. However, one-piece shredding rollers can also be used, on which axially spaced cutting elements or teeth are provided. Examples of both versions can be found in AT-B 350 988. 0
Ein Problem aller Abfallzerkleinerer liegt darin, daß die zu zerkleinernden Abfallmaterialien unterschiedli¬ che Eigenschaften aufweisen, sodaß die Zerkleinerungs- vorrichtungen nur mehr oder minder zufriedenstellend 5 funktionieren. Es kommt immer wieder vor, daß trotz einer möglichen Antriebsumkehr und in die Zwischenräume eingreifender Räumelemente das Material schlecht zer- kleinert und eingeklemmt wird. Die Vorrichtung muß dann für die Reinigung zumindest teilweise zerlegt werden.A problem of all waste shredders is that the waste materials to be shredded have different properties, so that the shredding devices only function more or less satisfactorily. It happens again and again that despite a possible drive reversal and clearing elements engaging in the gaps, the material is badly broken up. is shrunk and pinched. The device must then be at least partially disassembled for cleaning.
Die Erfindung hat es sich daher zur Aufgabe gestellt, die Funktionssicherheit einer derartigen Zerkleine¬ rungsvorrichtung zu verbessern, und insbesondere zu¬ sätzliche Freiräume zu schaffen, in die nicht oder nur schlecht zerkleinertes Material austreten kann, um die Blockierung der Vorrichtung zu vermeiden.The object of the invention is therefore to improve the functional reliability of such a comminution device, and in particular to create additional free spaces into which material which has not or only poorly comminuted can escape in order to avoid the device being blocked.
Erfindungsgemäß wird dies dadurch erreicht, daß die Zerkleinerungswalze hohl ausgebildet ist und in zu¬ mindest einer Stirnseite eine Öffnung aufweist, und daß die Zwischenräume zwischen den Schneidelementen jeweils in den Walzenhohlraum offen sind. Auf diese Weise kann Material, das nicht oder nur teilzerkleinert zwischen die Schneidelemente eindringt, sich nicht in den Zwi¬ schenräumen festlegen und diese verstopfen, sondern wird von nachfolgendem Material weiter in den Walzen- hohlrau gedrückt.This is achieved according to the invention in that the comminution roller is hollow and has an opening in at least one end face, and in that the gaps between the cutting elements are each open in the roller cavity. In this way, material that does not penetrate between the cutting elements, or only partially crushes them, cannot settle in the interstices and clog them, but is pressed further into the hollow cavity by the subsequent material.
Wird auch das Gegenschneidwerkzeug durch eine Zerklei¬ nerungswalze gebildet, die sich gegenläufig zur ersten Zerkleinerungswalze dreht und ebenfalls u fangseitige Schneidelemente aufweist, so sieht eine bevorzugte Aus¬ führung vor, daß auch die zweite Zerkleinerungswalze hohl ausgebildet ist und in zumindest einer Stirnseite eine Öffnung aufweist, wobei die Zwischenräume zwischen den Schneidelementen in den Walzenhohlraum offen sind.If the counter-cutting tool is also formed by a comminution roller which rotates in the opposite direction to the first comminution roller and likewise has cutting elements on the circumference, a preferred embodiment provides that the second comminution roller is also hollow and has an opening in at least one end face , wherein the spaces between the cutting elements in the roller cavity are open.
Um die Zwischenräume zwischen den Schneidelementen je¬ weils möglichst groß zu gestalten, sieht eine bevor¬ zugte Ausführung vor, daß die Schneidelemente als Längsstege ausgebildet sind, zwischen denen Längs- schlitze die in den Walzenhohlraum offenen Zwischen¬ räume bilden. Die Längsstege können dabei sowohl achsparallel als auch schräg zur Achse verlaufen. Be¬ vorzugt erweitern sich die Zwischenräume in den Walzen¬ hohlraum, sodaß das Material sich nicht verklemmen kann.In order to make the gaps between the cutting elements as large as possible, a preferred embodiment provides that the cutting elements are designed as longitudinal webs, between which longitudinal slots form the gaps open in the roller cavity. The longitudinal webs can both run parallel to the axis and at an angle to the axis. The spaces preferably expand into the roller cavity, so that the material cannot become jammed.
Das in die Walzenhohlräume eindringende Material tritt bei nicht horizontaler Lage der Walzen aufgrund der Schwerkraft nach unten durch die Öffnungen in den Stirnseiten aus. Bevorzugt wird jedoch in jedem Walzen- hohlraum ein zur offenen Stirnseite hin wirkendes Räum¬ element vorgesehen, sodaß eine Zwangsentleerung unab¬ hängig von der Lage der Zerkleinerungswalzen erfolgt. Das aus dem Walzenhohlraum austretende Material wird, je nach seinem Zerkleinerungsgrad, entweder zur weite- ren Zerkleinerung in die Zerkleinerungsvorrichtung zu¬ rückgegeben oder dem von den Walzen zerkleinerten Mate¬ rial zugegeben.The material penetrating into the roller cavities emerges through the openings in the end faces due to gravity when the rollers are not in a horizontal position. However, a clearing element which acts towards the open end face is preferably provided in each roller cavity, so that forced emptying takes place independently of the position of the comminution rollers. The material emerging from the roll cavity is, depending on its degree of comminution, either returned to the comminution device for further comminution or added to the material comminuted by the rolls.
Da sich die Walzen drehen, kann das Räumelement gehäu- sefest angeordnet sein. Ein derartiges Räumelement steht zumindest einseitig aus dem Walzenhohlraum vor und ist außerhalb am Gehäuse, insbesondere mittels einer Montagelasche od.dgl. befestigt. Das Räumelement besteht in einer ersten Ausführung aus einer der Walze angepaßt gekrümmten Platte, die mit oder ohne Abstand zur Walzeninnenseite achsparallel oder geneigt und in eine oder beide Drehrichtungen wirksam im Walzenhohl¬ raum angeordnet ist. In einer bevorzugten Ausführung weist die Platte eine etwa über ein Drittel des Umfan- ges sich erstreckende Trapezform auf, an deren Schmal¬ seite die Montagelasche vorgesehen ist. Die Schrägsei¬ ten der Platte bilden einerseits Räumkanten, entlang denen aufgrund der Walzendrehung das Material ausgetra¬ gen wird und können weiters auch als Schneidkanten wir- ken, die das durch die Zwischenräume eindringende Mate- rial an der Walzeninnenseite abscheren und damit zer¬ kleinern.Since the rollers rotate, the clearing element can be arranged fixed to the housing. Such a clearing element protrudes at least on one side from the roller cavity and is outside of the housing, in particular by means of a mounting bracket or the like. attached. In a first embodiment, the broaching element consists of a plate which is curved and adapted to the roller and which, with or without a distance from the inside of the roller, is axially parallel or inclined and is effectively arranged in one or both directions of rotation in the roller cavity. In a preferred embodiment, the plate has a trapezoidal shape extending over about a third of the circumference, on the narrow side of which the mounting bracket is provided. The inclined sides of the plate form broaching edges along which the material is discharged due to the rotation of the roller and can also act as cutting edges that penetrate the material penetrating through the spaces. shear off on the inside of the roller and thus shred.
Anstelle einer gehäusefesten Platte kann als Räumele¬ ment auch ein schraubenförmig gewendelter Steg, bei¬ spielsweise ein Abschnitt einer Förderschnecke im Wal¬ zenhohlraum angeordnet sein. Die Förderschnecke ist be¬ vorzugt ebenfalls gehäusefest; jedoch ist auch deren Antrieb denkbar.Instead of a plate fixed to the housing, a helically coiled web, for example a section of a screw conveyor, can also be arranged in the roller cavity as the clearing element. The screw conveyor is also preferably fixed to the housing; however, their drive is also conceivable.
Eine weitere Ausführung sieht vor, daß die zweite Stirnseite der Zerkleinerungswalze durch eine Abdeckung verschlossen ist. Da die beiden Walzen bzw. deren Schneidelemente in ümfangsrichtung formschlüssig inein- andergreifen, ist in einer weiteren bevorzugten Ausfüh¬ rung vorgesehen, daß der Antrieb nur einer Zerkleine¬ rungswalze zugeordnet ist. In diesem Fall ist es weiter von Vorteil, wenn die Schneidelemente der angetriebenen Zerkleinerungswalze breiter sind als die Schneidele- mente der zweiten Zerkleinerungswalze.Another embodiment provides that the second end face of the shredding roller is closed by a cover. Since the two rollers or their cutting elements interlock positively in the circumferential direction, a further preferred embodiment provides that the drive is assigned to only one comminution roller. In this case it is further advantageous if the cutting elements of the driven comminution roller are wider than the cutting elements of the second comminution roller.
Nachstehend werden zwei bevorzugte Ausführungen der Er¬ findung anhand der Figuren der beiliegenden Zeichnungen näher beschrieben, ohne darauf beschränkt zu sein.Two preferred embodiments of the invention are described in more detail below with reference to the figures in the accompanying drawings, without being limited thereto.
Es zeigen:Show it:

Fig. 3 eine Stirnansicht der Zerkleinerungsvorrich¬ tung nach Fig. 1 und 2, Fig. 4 einen Längsschnitt nach der Linie IV-IV der Fig. 5 durch eine zweite Ausführung und Fig. 5 einen Schnitt nach der Linie V-V der Fig. 4. Die erfindungsgemäße Zerkleinerungsvorrichtung weist ein rechteckiges Gehäuse 1 mit vier Seitenwänden 2 auf. Zwei Zerkleinerungswalzen 4,5 sind hohlzylindrisch aus¬ gebildet und mit ihren endseitigen Lagerabschnitten 3 in einander gegenüberliegenden Seitenwänden 2 drehbar gelagert. Zwischen den Lagerabschnitten 3 sind die bei¬ den Zerkleinerungswalzen 4,5 mit über den Umfang der Lagerabschnitte 3 vorstehenden, voneinander beabstande- ten Längsstegen 6 versehen. Diese bilden Schneidele- mente für das zu zerkleinernde Abfallmaterial und wei¬ sen Schneidkanten auf. Die Lagerabschnitte 3 können beispielsweise durch umfangsseitig genutete Ringe ge¬ bildet sein, in die an den Enden abgestufte Längsstege auswechselbar eingesetzt sind. Der Querschnitt der Längsstege entspricht dem eines Reißzahnes. Die Längs¬ stege 6 der einen Walze 4 greifen in die Zwischenräume zwischen den Längsstegen 6 der zweiten Walze 5 ein, so¬ daß ein zahnradartiger Eingriff zwischen den beiden Zerkleinerungswalzen 4,5 gegeben ist. Es genügt daher, nur der Walze 5 einen Antrieb 13 zuzuordnen. Die Zwi¬ schenräume zwischen den Längsstegen 6 sind in den Wal¬ zenhohlraum 8 offen, das heißt die Längsstege 6 sind durch Längsschlitze 7 voneinander getrennt. Von den Längsstegen 6 ergriffenes Material wird beim Durchgang zwischen den beiden Zerkleinerungswalzen 4,5 zer¬ kleinert und fällt nach unten. Nicht oder nur teilzer¬ kleinertes Material, das die Zwischenräume zwischen den Längsstegen 6 füllen und so die Funktion der Zerkleine¬ rungsvorrichtung beeinträchtigen könnte, wird durch die Längsschlitze 7 in die Walzenhohlräume 8 hineinge¬ drückt. Die Längsschlitze 7 erweitern sich für den leichteren Durchtritt des Materials nach innen. In je¬ dem Walzenhohlraum 8 ist ein Räumelement 9 gehäusefest angeordnet, das in der Ausführung nach den Fig. 1 bis 3 beispielsweise als trapezförmige, gekrümmte Platte aus¬ gebildet ist. Die Platte kann an der Innenseite der Walze 4,5 anliegend oder mit Abstand dazu sich parallel oder auch leicht geneigt zur Walzenachse erstrecken. Die schrägverlaufenden Seiten der Platte bilden für jede Drehrichtung eine Schneidkante, die durch die Längsschlitze 7 eintretendes Material zerkleinern bzw. abscheren kann und gleichzeitig eine Räumkante 11, ent¬ lang der das Material aus dem Walzenhohlraum 8 nach außen gefördert wird. Die Platte steht einseitig aus dem Walzenhohlraum 8 vor und ist mittels einer Montage- lasche 10 an der Außenseite der Gehäusewand 2 befe¬ stigt. An der der Austragseite des Materials gegenüber¬ liegenden Seite jeder Walze 4,5 ist eine Hohlraumab¬ deckung 12 vorgesehen, die an der angetriebenen Zer¬ kleinerungswalze 5 durch einen mit deren Lagerabschnitt 3 verbundenen Antriebsflansch gebildet ist.3 shows an end view of the comminution device according to FIGS. 1 and 2, FIG. 4 shows a longitudinal section along the line IV-IV of FIG. 5 through a second embodiment, and FIG. 5 shows a section along the line VV of FIG. 4. The shredding device according to the invention has a rectangular housing 1 with four side walls 2. Two shredding rollers 4, 5 are hollow-cylindrical and are rotatably supported with their end bearing sections 3 in opposite side walls 2. Between the bearing sections 3, the two comminuting rollers 4, 5 are provided with longitudinal webs 6, which protrude from the periphery of the bearing sections 3 and are spaced apart from one another. These form cutting elements for the waste material to be shredded and have white cutting edges. The bearing sections 3 can, for example, be formed by rings grooved on the circumference, into which longitudinal webs stepped at the ends are interchangeably inserted. The cross section of the longitudinal webs corresponds to that of a fang. The longitudinal webs 6 of the one roller 4 engage in the spaces between the longitudinal webs 6 of the second roller 5, so that there is a gear-like engagement between the two shredding rollers 4, 5. It is therefore sufficient to assign only one drive 13 to the roller 5. The interstices between the longitudinal webs 6 are open in the roller cavity 8, that is to say the longitudinal webs 6 are separated from one another by longitudinal slots 7. Material gripped by the longitudinal webs 6 is reduced in size as it passes between the two shredding rollers 4, 5 and falls downward. Material which is not or only partially shredded and which could fill the spaces between the longitudinal webs 6 and thus impair the function of the comminution device is pressed into the roller cavities 8 through the longitudinal slots 7. The longitudinal slots 7 widen inwards for easier passage of the material. In each roller cavity 8, a broaching element 9 is arranged fixed to the housing, which in the embodiment according to FIGS. 1 to 3 is designed, for example, as a trapezoidal, curved plate. The plate can be on the inside of the Roller 4,5 lying adjacent or at a distance from it extend parallel or slightly inclined to the roller axis. The sloping sides of the plate form a cutting edge for each direction of rotation, which can crush or shear material entering through the longitudinal slots 7 and at the same time a clearing edge 11 along which the material is conveyed out of the roller cavity 8 to the outside. The plate protrudes from the roller cavity 8 on one side and is attached to the outside of the housing wall 2 by means of a mounting bracket 10. On the side of each roller 4, 5 opposite the discharge side of the material, a cavity cover 12 is provided, which is formed on the driven shredding roller 5 by a drive flange connected to its bearing section 3.
Die Räumplatte 9 kann sich über einen Winkel zwischen etwa 60" und 300" und über jeden beliebigen Winkelbe¬ reich erstrecken. In der in den Figuren gezeigten Aus- führung verhindert die Anordnung der Räumplatten 9 im jeweils oberen Bereich der Walzen 4,5 das Eindringen von nicht dem Schneidwerk zugeführtem Material in die Walzenhohlräume 8.The broaching plate 9 can extend over an angle between approximately 60 "and 300" and over any angular range. In the embodiment shown in the figures, the arrangement of the broaching plates 9 in the upper region of the rollers 4, 5 prevents the penetration of material not fed into the cutting mechanism into the roller cavities 8.
In der Ausführung nach Fig. 4 und 5 ist das Räumelement 9 durch eine stillstehende Förderschnecke 17 gebildet, die eine plattenförmige Montagelasche 20 aufweist. Diese ist mittels Schrauben 21 an einer mit Abstand zu den Gehäusewänden 2 angeordneten weiteren Gehäusewand 18 befestigt. Die Förderschnecke 17 wird von einer4 and 5, the clearing element 9 is formed by a stationary screw conveyor 17 which has a plate-shaped mounting bracket 20. This is fastened by means of screws 21 to a further housing wall 18 arranged at a distance from the housing walls 2. The screw conveyor 17 is one

Dadurch ist ein zusätzliches Lager für die Zerkleinerungswalze 4,5 und eine Abstützung der Förderschnecke 17 auch im Inneren der Walze 4,5 gegeben. Durch die Drehung der Walze 4,5 wird das durchtretende Material entlang der Schrauben- fläche, der Förderschnecke nach außen befördert. Dort fällt es (Pfeile 19) ebenso nach unten wie zwischen den Walzen 4,5 zerkleinertes Material.
