Description
Die vorliegende Erfindung betrifft eine Zerkleinerungsvorrichtung zur Zerkleinerung von Material insbesondere in Form von Kunststoffen oder Abfallprodukten.The present invention relates to a comminution device for comminuting material, in particular in the form of plastics or waste products.
Gewerbeabfall, Industrieabfall, Hausabfall etc., beispielsweise (Hart-)Kunststoff, Textilien, Verbundstoffe, Gummi oder Althölzer (wie Paletten und Spanplatten), bedürfen vor ihrer endgültigen Entsorgung oder vor der Rückführung in den Wertstoffkreislauf der Zerkleinerung. Zur Zerkleinerung sind in dem Stand der Technik Ein- oder Mehrwellen - Zerkleinerer bekannt, welche beispielsweise durch Radlader, Gabelstapler oder Förderbänder oder auch manuell über einen Trichter zur Materialaufgabe beschickt werden.Industrial waste, industrial waste, household waste, etc., for example (hard) plastic, textiles, composites, rubber or waste wood (such as pallets and chipboard), require comminution before being finally disposed of or returned to the recycling cycle. For comminution, single or multi-shaft shredders are known in the prior art, which are fed, for example, by wheel loaders, forklifts or conveyor belts or manually via a hopper for material feed.
Ein zentrales Element eines herkömmlichen Zerkleinerers stellt eine Rotoreinheit dar, die einen Rotor umfasst, der mit Reißhaken oder Messern, die z. B. mit konkav geschliffenen Rundschneidkronen versehen sein können, bestückt ist. Die Messer sind beispielsweise durch Verschrauben an Messerträgern befestigt, die in Messertaschen eingeschweißt oder z. B. angeschraubt sein können, welche in den Rotor gefräst sind.A central element of a conventional crusher is a rotor unit comprising a rotor provided with tacks or knives, e.g. B. can be provided with concave ground Rundschneidkronen equipped. The knives are attached, for example, by screwing on knife carriers, which are welded in knife pockets or z. B. can be screwed, which are milled into the rotor.
Das aufgegebene Material kann durch eine beispielsweise lastabhängig gesteuerte Nachdrückeinrichtung, kurz als Nachdrücker bezeichnet, in Richtung des drehenden Rotors gedrückt werden. Nach der Zerkleinerung zwischen den rotierenden Messern und den Gegenmessern wird das Material typischerweise durch eine Siebeinrichtung, welche den Zerkleinerungsfaktor nach Maßgabe der Siebgröße bestimmt, ausgetragen und mithilfe eines Transportbandes, einer Transportschnecke, eines Kettenförderers oder einer Absauganlage usw. weiterbefördert.The discontinued material can be pressed in the direction of the rotating rotor by means of, for example, a load-dependent controlled pushing-in device, referred to for short as a push-pull device. After crushing between the rotating knives and the counter knives, the material is typically discharged through a sieve which determines the crushing factor in accordance with the size of the sieve and conveyed by means of a conveyor belt, a screw conveyor, a chain conveyor or an exhaust system.
Unabhängig von der Bauform sind in einer Zerkleinerungsvorrichtung Wartungs-und/oder Reinigungstätigkeiten der Vorrichtung durchzuführen. Zu den typischen Wartungstätigkeiten zählen der Wechsel der Zerkleinerungsmesser am Rotor und die Reinigung des Innenraums der Vorrichtung. Der Zugang zum Maschineninnenraum für eine Reinigung ist im Stand der Technik nur nach einer aufwändigen Demontage von Maschinenkomponenten, beispielsweise von Hydraulikzylindern, die einen Nachdrücker oder eine Wartungsklappe bewegen, möglich. Allgemein ist der Bereich des Rotors und der Gegenmesser schwer zugänglich.Regardless of the design, maintenance and / or cleaning operations of the device are to be performed in a shredding device. Typical maintenance activities include the change of the crushing blades on the rotor and the cleaning of the interior of the device. The access to the machine interior for cleaning is possible in the prior art only after a complex dismantling of machine components, such as hydraulic cylinders that move a push button or a maintenance cover. Generally, the area of the rotor and the counter-knife are difficult to access.
Es ist somit angesichts der genannten Probleme eine Aufgabe der vorliegenden Erfindung, eine Zerkleinerungsvorrichtung bereitzustellen, in der die Wartung und/oder Reinigung im Vergleich zum bekannten Stand der Technik durch eine Verringerung der notwendigen Demontage von Bauelementen erleichtert wird.It is thus an object of the present invention, in view of the above-mentioned problems, to provide a crushing device in which maintenance and / or cleaning is facilitated by reducing the necessary disassembly of components in comparison to the known prior art.
Die obige Aufgabe wird durch eine Zerkleinerungsvorrichtung gemäß Anspruch 1 gelöst.The above object is achieved by a crushing device according to claim 1.
Die Erfindung stellt eine Zerkleinerungsvorrichtung zum Zerkleinern von Material bereit, umfassend: ein Gehäuse; einen Rotor und ein oder mehrere Gegenmesser, die in dem Gehäuse so angeordnet sind, dass sie zum Zerkleinern des Materials zusammenwirken; einen Nachdrücker, der so bewegbar ist, dass er das Material zum Zerkleinern in Richtung zu Rotor und Gegenmesser drückt; einen Trichter zum Zuführen des Materials, der bewegbar auf dem Gehäuse zwischen einer ersten und einer zweiten Position angeordnet ist, wobei in seiner ersten Position das Material zu Rotor und Gegenmesser zuführbar ist und in seiner zweiten Position Rotor und Gegenmesser von außerhalb der Zerkleinerungsvorrichtung frei zugänglich sind.The invention provides a shredder for shredding material, comprising: a housing; a rotor and one or more counter-blades disposed in the housing so as to cooperate to comminute the material; a pusher movable to urge the material to be crushed toward the rotor and the counter knife; a hopper for feeding the material movably mounted on the housing between a first and a second position, wherein in its first position the material is deliverable to the rotor and the counterknife and in its second position the rotor and counterknife are freely accessible from outside the shredding device ,
Der Rotor und die ein oder mehreren Gegenmesser bilden einen Zerkleinerungs- oder Arbeitsbereich. In dem Arbeitsbereich wirken Rotor und Gegenmesser zur Zerkleinerung des Materials zusammen. Der Rotor und die Gegenmesser können besonders einfach erreicht werden, wenn der Trichter zum Zuführen des Materials bewegbar ist. Somit kann der Trichter aus einer ersten Position, die eine Arbeitsposition der Vorrichtung und insbesondere des Trichters ist, in eine zweite Position bewegt werden, wobei die zweite Position eine Wartungs- und/oder Reinigungsposition der Vorrichtung ist. Durch das Bewegen des Trichters in die zweite Position sind Rotor und Gegenmesser von außerhalb der Vorrichtung frei zugänglich. Das heißt, ein Nutzer der Anlage, der die Wartung / Reinigung von Rotor und/oder Gegenmessern durchführen möchte, hat somit freien Zugang zu Rotor und Gegenmesser, also zum Arbeitsbereich. Dabei ist der Zugang insbesondere durch eine Öffnung im Gehäuse der Vorrichtung möglich, durch die vorher das zu zerkleinernde Material aus dem Trichter in den Innenraum des Gehäuses der Vorrichtung gelangt. Beispielsweise fällt das zu zerkleinernde Material dort in den Innenraum des Gehäuses der Vorrichtung.The rotor and the one or more counter blades form a crushing or working area. In the working area, the rotor and the counter knife act together to shred the material. The rotor and the counter blades can be achieved particularly easily when the hopper is movable for feeding the material. Thus, the hopper can be moved from a first position, which is a working position of the device and in particular of the hopper, into a second position, wherein the second position is a maintenance and / or cleaning position of the device. By moving the funnel to the second position, the rotor and the counter knife are freely accessible from outside the device. That is, a user of the facility, the maintenance / cleaning of rotor and / or counter knives, thus has free access to the rotor and counter blade, so the work area. In this case, access is possible, in particular, through an opening in the housing of the device, through which the material to be shredded previously passes from the funnel into the interior of the housing of the device. For example, the material to be crushed falls there in the interior of the housing of the device.
In der Zerkleinerungsvorrichtung kann der Trichter gegenüber dem Gehäuse verschiebbar sein.In the crushing device, the hopper may be displaceable relative to the housing.
Durch die Verschiebbarkeit des Trichters gegenüber dem Gehäuse kann der Trichter auf besonders einfache Weise gegenüber dem Gehäuse von der ersten Position in die zweite Position verschoben werden. Ebenso kann der Trichter dadurch auf besonders einfache Weise wieder in die erste Position zurück geschoben werden.Due to the displaceability of the funnel with respect to the housing, the funnel can be moved in a particularly simple manner relative to the housing from the first position to the second position. Likewise, the funnel can be pushed back into the first position in a particularly simple manner.
In der Zerkleinerungsvorrichtung können ein oder mehrere Führungsnuten oder Schienen auf dem Gehäuse zur Führung des Trichters vorgesehen sein.In the crushing device, one or more guide grooves or rails may be provided on the housing for guiding the hopper.
Die Führungsschienen oder Führungsnuten auf dem Gehäuse ermöglichen es, den Trichter derart zu bewegen, dass er geführt auf dem Gehäuse verschoben wird. Dadurch kann die Bewegung des Trichters von der ersten Position in die zweite Position besonders gut definiert werden. Der Trichter kann beispielsweise über die Führungsschienen zusätzlich gesichert werden, so dass er während des Verschiebens sind nicht von dem Gehäuse, also von der Gehäuseoberfläche, lösen kann.The guide rails or guide grooves on the housing make it possible to move the funnel so that it is displaced guided on the housing. As a result, the movement of the funnel from the first position to the second position can be defined particularly well. The funnel can be additionally secured, for example, via the guide rails, so that it can not come loose from the housing, ie from the housing surface, during the movement.
In der Zerkleinerungsvorrichtung kann ein Antrieb zum Bewegen des Trichters vorgesehen sein, wobei der Antrieb als Linearantrieb ausgebildet sein kann.In the crushing device, a drive for moving the hopper may be provided, wherein the drive may be designed as a linear drive.
Das Bewegen des Trichters kann vorteilhafterweise durch einen Antrieb geschehen. Da die Masse des Trichters in der Regel groß sein kann, kann über einen Antrieb eine möglichst präzise Bewegung des Trichters gegenüber dem Gehäuse gewährleistet werden. Dies kann insbesondere durch einen Linearantrieb geschehen. Dadurch kann die translatorische Bewegung des Trichters von der ersten Position in die zweite Position entsprechend einem vorgegebenen Verlauf gewährleistet werden.The movement of the funnel can advantageously be done by a drive. Since the mass of the funnel can be large as a rule, a drive as precise as possible movement of the funnel relative to the housing can be ensured. This can be done in particular by a linear drive. Thereby, the translational movement of the funnel can be ensured from the first position to the second position according to a predetermined course.
In der Zerkleinerungsvorrichtung kann der Trichter an einer Drehachse schwenkbar ausgebildet sein.In the comminution device, the funnel can be designed to be pivotable on a rotation axis.
Ein schwenkbarer Trichter an einer Drehachse kann aus der ersten Position herausgeschwenkt und in die zweite Position hinein geschwenkt werden. Dadurch kann eine einfache Zugangsmöglichkeit zum Rotor und/oder zu den Gegenmessern erzielt werden. Durch das Schwenken des Trichters um eine Drehachse kann die Bewegung des Trichters auf die Schwenkbahn begrenzt werden, wodurch eine präzise Bewegung des Trichters gewährleistet werden kann.A pivotable hopper on an axis of rotation can be swung out of the first position and pivoted into the second position. As a result, a simple access to the rotor and / or the counter knives can be achieved. By pivoting the funnel about an axis of rotation, the movement of the funnel can be limited to the pivoting path, whereby a precise movement of the funnel can be ensured.
In der Zerkleinerungsvorrichtung kann ein Antrieb zum Schwenken des Trichters um die Drehachse vorgesehen sein.In the comminution device, a drive for pivoting the funnel about the axis of rotation may be provided.
Wird der Trichter um die Drehachse geschwenkt, so kann ebenfalls ein Antrieb verwendet werden, um den Trichter in kontrollierter Weise aus der ersten Position in die zweite Position zu schwenken. Gleiches gilt, wenn der Trichter nach erfolgter Reinigung des Rotors und / oder der Gegenmesser wieder in die erste Position, also in die Arbeitsstellung, zurück geschwenkt wird.If the hopper is pivoted about the axis of rotation, then a drive can also be used to pivot the hopper in a controlled manner from the first position to the second position. The same applies if the funnel after cleaning the rotor and / or the counter knife back to the first position, ie in the working position, is pivoted back.
In der Zerkleinerungsvorrichtung der Antrieb mechanisch und/oder pneumatisch und/oder hydraulisch und/oder als Kettenantrieb ausgebildet sein.In the comminution device, the drive may be constructed mechanically and / or pneumatically and / or hydraulically and / or as a chain drive.
Es können entsprechend von konkreten Nutzungsanforderungen verschiedene Antriebsarten wie ein mechanischer und/oder pneumatischer und/oder hydraulischer Antrieb und/oder Kettenantrieb eingesetzt werden. Insbesondere können diese Antriebsarten auch kombiniert werden.It can be used according to specific usage requirements different types of drives such as a mechanical and / or pneumatic and / or hydraulic drive and / or chain drive. In particular, these types of drives can also be combined.
In der Zerkleinerungsvorrichtung kann der Trichter mit dem Nachdrücker derart koppelbar sein, dass der Trichter durch Bewegen des Nachdrückers bewegbar ist.In the crushing device, the hopper may be coupled to the pusher such that the hopper is movable by moving the pusher.
Wird der Trichter mit dem Nachdrücker gekoppelt, so kann der Trichter durch Steuern des Nachdrückers bewegt werden. Durch die Kopplung kann der Antrieb des Nachdrückers kombiniert sowohl den Nachdrücker als auch den Trichter bewegen. Dadurch ergibt sich eine besonders einfache und kompakte Bauweise für die Vorrichtung. Die Kopplung kann durch ein Kopplungsglied, etwa ein Verbindungsstück, manuell vorgenommen werden. Beispielsweise kann ein Kopplungsglied am Nachdrücker und/oder am Trichter einhakbar vorgesehen sein. Es kann ebenso möglich sein, eine elektromagnetische oder eine hydraulische Kopplung vorzunehmen. Wenn der Nachdrücker in die zweite Position fährt, also wenn der Nachdrücker sich von Rotor und Gegenmesser weg bewegt, kann er somit in effizienter Weise den Trichter mitbewegen. Dabei bewegen sich Trichter und Nachdrücker typischerweise in die gleiche Richtung.If the funnel is coupled to the pusher, the funnel can be moved by controlling the pusher. The coupling allows the drive of the pusher to combine both the pusher and the hopper. This results in a particularly simple and compact design for the device. The coupling can be done manually by a coupling member, such as a connector. For example, a coupling member on the pusher and / or on the Hopper einhakbar be provided. It may also be possible to perform an electromagnetic or a hydraulic coupling. As the pusher moves to the second position, that is, as the pusher moves away from the rotor and counter knife, it can thus efficiently move the funnel. The funnels and push-pulls typically move in the same direction.
In der Zerkleinerungsvorrichtung kann der Nachdrücker mit dem Trichter in der ersten Position koppelbar sein.In the crushing device, the pusher can be coupled to the hopper in the first position.
Die Kopplung kann vorteilhafterweise in der ersten Position ausgeführt werden. Der Nachdrücker arbeitet üblicherweise während der normalen Zerkleinerungstätigkeit der Zerkleinerungsvorrichtung unabhängig vom Trichter. Zum Zwecke einer Wartung oder Reinigung des Arbeitsbereichs kann der Nachdrücker in eine Position bewegt werden, wo sich der Kopf des Nachdrückers nahe an dem Rotor und den Gegenmessern befindet, der Nachdrücker also weit oder sogar maximal in Richtung auf den Rotor bewegt ist, beispielsweise ausgefahren ist. Ein Koppeln des Nachdrückers mit dem Trichter, der sich in der bereits oben definierten ersten Position befindet, kann gewährleisten, dass der Nachdrücker einen besonders großen Hub hat, um den Trichter zu bewegen, wenn der Nachdrücker in die zweite Position fährt.The coupling can be advantageously carried out in the first position. The pusher usually operates during the normal crushing operation of the crusher independently of the hopper. For the purpose of maintenance or cleaning of the working area, the pusher can be moved to a position where the head of the pusher is close to the rotor and the counter knives, ie the pusher is moved far or even maximally in the direction of the rotor, for example extended , Coupling the pusher with the hopper, which is in the first position already defined above, can ensure that the pusher has a particularly large stroke to move the hopper as the pusher moves to the second position.
In der Zerkleinerungsvorrichtung kann der Nachdrücker durch einen weiteren Antrieb bewegbar sein, der mechanisch und/oder pneumatisch und/oder hydraulisch und/oder als Kettenantrieb ausgebildet sein kann.In the comminution device, the repulsion device can be moved by a further drive, which can be designed mechanically and / or pneumatically and / or hydraulically and / or as a chain drive.
Es kann anwendungsbedingt ebenso vorteilhaft sein, Nachdrücker und Trichter unabhängig voneinander anzutreiben, was insbesondere bei sehr unterschiedlichen Größen von Nachdrücker und Trichter vorteilhaft sein kann. Dazu kann ein weiterer Antrieb verwendet werden.It can also be advantageous for the application to drive the pusher and hopper independently of one another, which can be advantageous in particular for very different sizes of pusher and hopper. For this purpose, another drive can be used.
In der Zerkleinerungsvorrichtung kann der Nachdrücker so vorgesehen sein, dass er während des Zerkleinerungsbetriebs vollständig im Gehäuse verbleibt.In the crushing apparatus, the pusher may be provided so as to remain completely in the casing during the crushing operation.
Dadurch kann die Zerkleinerungsvorrichtung besonders kompakt gestaltet werden.As a result, the crushing device can be made particularly compact.
Die Zerkleinerungsvorrichtung kann ein Einwellenzerkleinerer mit stationären Gegenmesser oder Gegenmessern sein oder ein Mehrwellenzerkleinerer mit auf einem weiteren Rotor angeordneten Gegenmesser oder Gegenmessern sein.The comminution device can be a single-shaft shredder with stationary counter-blades or counter-blades or a multi-shaft shredder with counter-blades or counter-blades arranged on a further rotor.
Die Zerkleinerungsvorrichtung kann also verschiedene gängige Typen von Einwellen-oder Mehrwellenzerkleinerern umfassen und kann somit an verschiedene Nutzungsanforderung angepasst werden.The comminution device can thus comprise various common types of single-shaft or multi-shaft shredders and can thus be adapted to different usage requirements.
