Description

Die vorliegende Erfindung betrifft eine Zerkleinerungsmaschine, insbesondere zum Zerspanen von faserigem Gut, speziell zum Zerhacken von Holz. Herkömmliche Zerkleinerungsmaschinen weisen zum Abtransport der Hackschnitzel eine Förderschnecke auf, die im wesentlichen parallel zur Rotorachse angeordnet ist und die beim Zerkleinerungsvorgang anfallenden Schnitzel abtransportiert. Eine gegebenenfalls hinter der Schnecke angeordnete Saugeinrichtung transportiert die Hackschnitzel von der Schnecke zu einem Auswurfschacht. Diese Anordnung hat den Nachteil, daß die Förderschnecke die Anordnung verkompliziert und verteuert.The present invention relates to a comminution machine, in particular for cutting fibrous material, especially for chopping wood. Conventional shredding machines have a screw conveyor for the removal of the chips, which is arranged essentially parallel to the rotor axis and transports the chips that occur during the shredding process. A suction device, which may be arranged behind the screw, transports the wood chips from the screw to an ejection chute. This arrangement has the disadvantage that the screw conveyor complicates and increases the cost of the arrangement.

Aufgabe der vorliegenden Erfindung ist die Angabe einer Zerkleinerungsmaschine, die geeignet ist, ohne eine Förderschnecke zu arbeiten.The object of the present invention is to provide a comminution machine which is suitable for working without a screw conveyor.

Erfindungsgemäß wird angegebenen eine Zerkleinerungsmaschine mit einem Rotorraum, einem in den Rotorraum eingeführten Förderband zum Abführen von zu zerkleinerndem Gut und einem in dem Rotorraum drehbar angeordneten Hackrotor, die dadurch gekennzeichnet ist, daß radial außerhalb des Rotors ein Sauggebläse vorgesehen ist, dessen Achse im wesentlichen quer zur Rotorachse angeordnet ist. Die erfindungsgemäße Zerkleinerungsmaschine zeichnet sich durch eine in Form eines Sauggebläses ausgebildete Saugeinrichtung aus, die radial außerhalb des Rotors derart angeordnet ist, daß sie die von dem Rotor erzeugten Hackschnitzel unmittelbar hinter dem Rotor aufnimmt und abtransportiert. Die Anordnung einer Förderschnecke entfällt.According to the invention, a comminution machine is specified with a rotor chamber, a conveyor belt introduced into the rotor chamber for removing material to be comminuted and a chopping rotor rotatably arranged in the rotor chamber, which is characterized in that a suction fan is provided radially outside the rotor, the axis of which is essentially transverse is arranged to the rotor axis. The shredding machine according to the invention is characterized by a suction device in the form of a suction fan, which is arranged radially outside the rotor in such a way that it picks up and transports the wood chips generated by the rotor directly behind the rotor. The arrangement of a screw conveyor is omitted.

Bevorzugt ist das Gebläse auf einer dem Förderband bezüglich des Rotors gegenüberliegenden Seite des Rotors angeordnet. Mit dieser Anordnung wird das auf dem Förderband transportierte zu zerkleinernde Gut vom Rotor erfaßt und tangential in einen dem Förderband gegenüberliegenden Bereich des Rotorraums transportiert, von wo es der Saugwirkung des Gebläses unterliegend abtransportiert wird.The fan is preferably arranged on a side of the rotor opposite the conveyor belt with respect to the rotor. With this arrangement, that will Goods to be shredded transported on the conveyor belt are gripped by the rotor and transported tangentially into an area of the rotor space opposite the conveyor belt, from where it is transported away under the suction effect of the fan.

Die Gebläseachse ist in der Betriebsposition der Zerkleinerungsmaschine tiefer gelegen als die Rotorachse. Dadurch wird dem Umstand Rechnung getragen, daß der Ort der Zerkleinerung im Bereich der unteren Peripherie des Hackrotors liegt, wobei die Hackschnitzel aufgrund der Schwerkraft eine nach unten gerichtete tangential von der Rotorperipherie ausgehende Bahn beschreiben. Das unterhalb der Rotorachse angeordnete Sauggebläse nimmt diese Hackschnitzel bequem auf.In the operating position of the shredding machine, the blower axis is located lower than the rotor axis. This takes account of the fact that the location of the comminution is in the region of the lower periphery of the chopping rotor, the chips, due to gravity, describing a downward tangential path from the rotor periphery. The suction fan, which is located below the rotor axis, easily takes up these wood chips.

Es ist bevorzugt, daß ein Trennsieb zwischen Rotor und Gebläse angeordnet ist. Ein derartiges Trennsieb hat eine derart eingestellte Maschenweite, daß nur Hackschnitzel mit einer Abmessung unterhalb der Maschenweite hindurchtreten und abtransportiert werden. Das Trennsieb ist an die Rotorperipherie angepaßt und hat daher im Querschnitt einen zumindest abschnittsweise kreisförmigen Verlauf.It is preferred that a separating screen is arranged between the rotor and the fan. Such a separating sieve has a mesh size set in such a way that only wood chips with a dimension below the mesh size pass through and are transported away. The separating screen is adapted to the rotor periphery and therefore has an at least partially circular profile in cross section.

Das Förderband ist in einer Ausführungsform im Bereich des Rotorraums abgewinkelt und in einen Bereich unterhalb des Rotors verlängert. Bei dieser Anordnung wird sichergestellt, daß im Bereich des Rotors nach unten abgehende Hackschnitzel auf einen Bereich des abgewinkelten Förderbandabschnitts auftreffen und weiter in Richtung des Gebläses transportiert werden. Auf diese Weise kann ein Abgehen der Hackschnitzel nach unten verhindert werden.In one embodiment, the conveyor belt is angled in the area of the rotor space and extended into an area below the rotor. With this arrangement it is ensured that in the area of the rotor downward chips come into contact with an area of the angled conveyor belt section and are transported further in the direction of the blower. In this way, the chips can be prevented from going down.

Alternativ ist ein weiteres Fördermittel unterhalb des Rotors angeordnet, welches mit dem Förderband zusammenwirkt. In dieser Anordnung ist ein separates Fördermittel, beispielsweise ein Förderband, unterhalb des Rotors vorgesehen, um nach unten abgehende Hackschnitzel in Richtung Gebläse zu transportieren, damit auch diese Hackschnitzel noch vom Gebläse aufgenommen werden können.

Fig. 1
zeigt einen Querschnitt einer Ausführungsform der erfindungsgemäßen Zerkleinerungsmaschine.
Alternatively, a further conveyor is arranged below the rotor, which interacts with the conveyor belt. In this arrangement, a separate conveying means, for example a conveyor belt, is provided below the rotor in order to transport wood chips going downwards in the direction of the blower so that these wood chips are also still picked up by the blower can.
Fig. 1
shows a cross section of an embodiment of the shredding machine according to the invention.

Ein Hackrotor 4 ist mit seiner Rotorachse 1 in einem Rotorraum 2 drehbar gelagert. Unterhalb der Rotorachse 1 und links von ihr ist in horizontaler Richtung ein Förderband 6,8 geführt, das im Bereich des Rotorraums 2 in einem stumpfen Winkel abgewinkelt ist. Ein Förderbandabschnitt 6 verläuft annähernd horizontal, während an einer Abwinklungsstelle, beispielsweise einer Rolle, ein Förderbandabschnitt 8 beginnt, der bis in einen Bereich unterhalb des Rotors 4 bzw. des Rotorraums 2 verlängert ist.A chopping rotor 4 is rotatably mounted with its rotor axis 1 in a rotor space 2. Below the rotor axis 1 and to the left of it, a conveyor belt 6, 8 is guided in a horizontal direction, which is angled at an obtuse angle in the area of the rotor space 2. A conveyor belt section 6 runs approximately horizontally, while at a bend point, for example a roller, a conveyor belt section 8 begins, which is extended to a region below the rotor 4 or the rotor space 2.

Oberhalb des Förderbands 6 befindet sich ein Gegenförderband 10, das an seiner oberen Rolle fest gelagert ist, wobei seine untere Rolle frei tragend ist, so daß das Förderband 10 je nach Größe des herangeförderten Zerkleinerungsgutes mehr oder weniger geneigt ist. Radial außerhalb des Hackrotors 4 ist angepaßt an den Hackrotorumfang ein Trennsieb 18 vorgesehen, das den Rotorraum 2 begrenzt und in seiner Maschenweite so gewählt ist, daß nur genügend feine Hackschnitzel mit einem Durchmesser unterhalb der Maschenweite den Rotorraum verlassen können.Above the conveyor belt 6 there is a counter conveyor belt 10 which is fixedly mounted on its upper roller, its lower roller being self-supporting, so that the conveyor belt 10 is more or less inclined depending on the size of the material to be conveyed. Radially outside of the chopping rotor 4, a separating screen 18 is provided, adapted to the chopping rotor circumference, which delimits the rotor space 2 and is selected in its mesh size such that only sufficiently fine chips with a diameter below the mesh size can leave the rotor space.

Außerhalb des Trennsiebs 18 befindet sich ein Sauggebläse 12, dessen Achse 14 im wesentlichen horizontal und senkrecht zur Rotorachse 1 angeordnet ist. Die Gebläseachse 14 befindet sich unterhalb der Rotorachse 1 und ist ebenfalls tiefer gelegen als das Obertrum des Förderbandabschnitts 6. Das Sauggebläse 12 weist Schaufelblätter 16 auf, die aufgrund ihrer Schrägstellung eine Saugwirkung entfalten. Der Gesamtdurchmesser des Sauggebläses 12 ist gewählt, daß sich die Schaufelblätter bis in den Bereich des Mittelpunkts der Rotorachse 1 nach oben erstrecken. Der Gesamtdurchmesser des Gebläses ist ferner so gewählt, daß es die Gesamtlänge des Rotors abdeckt, so daß das Gebläse in seiner gesamten Tiefe eine ausreichende Saugwirkung entfaltet, um alle aus dem Rotorraum austretenden Hackschnitzel aufzunehmen. Der unterhalb des Rotorraums 2 verlängerte Förderbandabschnitt 8 stellt sicher, daß nach unten abgehende Hackschnitzel vom Förderband 8 in Richtung des Gebläses 12 mitgenommen werden. Besonders bevorzugt ist das Sauggebläse an seiner Ansaugöffnung im Querschnitt verkleinert (nicht gezeigt), um eine erhöhte Saugwirkung zu erzielen.Outside the separating screen 18 there is a suction blower 12, the axis 14 of which is arranged essentially horizontally and perpendicular to the rotor axis 1. The fan axis 14 is located below the rotor axis 1 and is also located lower than the upper run of the conveyor belt section 6. The suction fan 12 has blades 16 which, due to their inclined position, exert a suction effect. The overall diameter of the suction fan 12 is chosen so that the airfoils extend up to the region of the center point of the rotor axis 1. The overall diameter of the blower is also selected so that it covers the entire length of the rotor, so that the blower unfolds a sufficient suction effect in its entire depth to all from the Rotor chips emerging from the rotor chamber. The conveyor belt section 8, which is elongated below the rotor space 2, ensures that chips going downward are taken along by the conveyor belt 8 in the direction of the blower 12. The suction fan is particularly preferably reduced in cross-section at its suction opening (not shown) in order to achieve an increased suction effect.

Bei der erfindungsgemäßen Zerkleinerungsmaschine entfällt aufgrund der erfindungsgemäß vorgesehenen Gebläseanordnung eine im Stand der Technik vorgesehene Förderschnecke, so daß die erfindungsgemäße Zerkleinerungsmaschine erheblich kostengünstiger und mechanisch weniger aufwendig hergestellt werden kann.In the shredding machine according to the invention, a conveyor screw provided in the prior art is omitted due to the blower arrangement provided according to the invention, so that the shredding machine according to the invention can be manufactured considerably more cost-effectively and mechanically less expensively.
