Abstract
Description
Die Erfindung betrifft eine Zerkleinerungsmaschine zum Zerkleinern von Material, mit einem Zerkleinerungswerkzeuge aufweisenden Rotor und mit einem die Austrittsgröße des zerkleinerten Materials bestimmenden Rost, der am Materialauslass einem Teil des Umfangs des Rotors zugeordnet ist.The invention relates to a crushing machine for crushing material, with a crusher having rotor and with a the discharge size of the crushed material determining rust, which at the material outlet a part associated with the circumference of the rotor.
Bei derartigen Zerkleinerungsmaschinen ist dem Verwendungszweck entsprechend der Materialauslass mit einer Vielzahl von Öffnungen versehen, wenn eine gewünschte Austrittsgröße sichergestellt werden soll, da die Öffnungen nur von kleinerem Material passiert werden, während größere Stücke wieder nach oben gefördert und solange einer nochmaligen Zerkleinerung unterliegen, bis sie durch die Öffnungen fallen.In such crushers is the intended use accordingly the material outlet provided with a plurality of openings, if desired Exit size should be ensured since the openings are only of smaller material to be passed while larger pieces are promoted back up and as long subject to repeated comminution until they fall through the openings.
Bei Maschinen für eine Nachzerkleinerung sind die Öffnungen meist in einem gebogenen Lochblech gebildet, da die Belastungen geringer sind. Maschinen für eine Vor- bzw. Hauptzerkleinerung (beispielsweise nach der EP 254 173 A) sind, insbesondere für harte und gemischte Materialien, mit Gitterrosten versehen, die durch einander kreuzende Stege entsprechender Höhe gebildet sind. Ein Rost mit parallelen, schräg verlaufenden Stegen, die eine scherende Wirkung ausüben, ist aus der DE 138 672 C bekannt. Die Stege sind auf drei sich in Richtung der Rotorachse erstreckenden Stangen aufgefädelt. Zwei den Materialauslass jeweils bis zu einer mittleren Längsschiene überspannenden Stabroste mit unterschiedlichen Spaltenbreiten sind aus der DE 195 47 828 bekannt. Verstellbare Abdeckungen sind vorgesehen, um das zerkleinerte Material nur den die gewünschte Korngröße bestimmenden Spalten zuzuführen. Auch nach der EP 254 173 A sind Maßnahmen vorgesehen, um die Größe der Gitteröffnungen zu verändern, beispielsweise indem dem Gitterrost eine Patrize zugeordnet ist, deren Erhebungen bis zum völligen Verschluss unterschiedlich weit in die Gitteröffnungen eingeschoben werden.In machines for post-shredding the openings are usually in one formed bent perforated plate, since the loads are lower. Machines for one Primary or primary comminution (for example according to EP 254 173 A), especially for hard and mixed materials, provided with gratings by Intersecting webs corresponding height are formed. A rust with parallel, oblique webs, which exert a shearing effect, is known from DE 138 672 C known. The webs are on three extending in the direction of the rotor axis Threaded rods. Two each the material outlet up to a middle one Longitudinal rail spanning bar grates with different column widths are known from DE 195 47 828. Adjustable covers are provided to the crushed material only the desired grain size determining columns supply. Also according to EP 254 173 A measures are provided to the size to change the grid openings, for example by the grid a male is assigned, whose surveys until the complete closure different far in the grid openings are inserted.
Ein wesentliches Problem aller genannten Lochsiebe, Gitterroste und Stabroste liegt darin, dass die Öffnungen und Spalte nicht nur von Randabschnitten begrenzt sind, die sich in Umfangsrichtung erstrecken, sondern zwangsläufig auch Randabschnitte aufweisen, die quer dazu verlaufen. Diese bei runden Löchern gebogenen, und bei rechteckigen Gitteröffnungen sowie bei in Richtung der Rotorachse sich erstreckenden Stangen und Schienen geraden, senkrecht zur Umfangrichtung verlaufenden Randabschnitte stellen Kanten dar, die zu große Materialstücke, die vom Rotor zurück nach oben befördert werden müssen, daran hindern, den Rost bis zum Ende entlang zu gleiten. Die quer verlaufenden Randabschnitte können Hindernisse bilden, die den Rotor blockieren, oder werden von dem Material umwickelt, wenn es sich beispielsweise um Folien od. dgl. handelt. Diese unerwünschten Beanspruchungen erfordern eine massivere und teurere Konstruktion und erhöhen die Gefahr der Beschädigung des Lochsiebes oder Rostes oder der Schneidwerkzeuge des Rotors beträchtlich. Durchgehend schräge Roststäbe bewirken zusätzlich eine ungünstige Förderung des nicht zerkleinerten Materials in axialer Richtung zum einen Ende hin, an dem es sich staut und die Vorrichtung axial belastet.A major problem of all mentioned perforated screens, gratings and bar grates is in that the openings and gaps are not limited only by edge portions which extend in the circumferential direction, but inevitably edge portions have, which run transversely to it. These curved at round holes, and at rectangular grid openings as well as in the direction of the rotor axis extending Rods and rails straight, perpendicular to the circumferential direction Edge sections represent edges that are too large pieces of material coming back from the rotor must be transported to the top, preventing the rust to the end along to glide. The transverse edge portions can form obstacles that the Block the rotor, or be wrapped by the material when it is for example, to films od. Like. Acts. These undesirable stresses require a more massive and expensive construction and increase the risk of Damage to the perforated sieve or grate or cutting tools of the rotor considerably. Continuously sloping grate bars additionally cause an unfavorable Promotion of the non-crushed material in the axial direction to one end, to it jams and loads the device axially.
Die Erfindung hat sich nun zur Aufgabe gestellt, diese Nachteile zu vermeiden und erreicht dies dadurch dass der Rost den Materialauslass überspannende, zueinander parallele Roststäbe aufweist, zwischen denen durchgehende Durchtrittsspalte vorgesehen sind.The invention has now taken on the task of avoiding these disadvantages and This achieves this by the rust spanning the material outlet to each other has parallel grate bars, between which continuous passage column are provided.
Wie sich herausgestellt hat, ist eine Passage des Materials durch die Rostöffnungen nahezu ausschließlich von der Größe der Erstreckung der Öffnung parallel zur Rotorachse bestimmt. Materialstücke, die größer sind, liegen beidseitig auf den Roststäben auf, und sie werden, da über den gesamten Rostbereich sämtliche nicht parallel zur Umfangsrichtung verlaufenden Kanten der Rostöffnungen fehlen, mit geringem Reibungswiderstand den Rost entlang nach oben gefördert. Maßgeblich für die Korngröße ist somit die Breite und nicht die Länge der Durchtrittsspalte zwischen den Roststäben.As it turns out, there is a passage of material through the grate openings almost exclusively the size of the extension of the opening parallel to the Rotor axis determined. Material pieces that are larger, lie on both sides of the Rust bars on, and they are, as over the entire grate area all not missing parallel to the circumferential direction edges of the grate openings, with low frictional resistance along the grate conveyed upwards. Decisive for the grain size is thus the width and not the length of the passage gaps between the grate bars.
Bevorzugt weisen Roststäbe, die insbesondere über etwa 150° gebogen sind, an den Enden Befestigungsfortsätze auf, die aus dem Krümmungsbereich nach außen geführt sind. Mittels der Befestigungsfortsätze können die Roststäbe an maschinenfesten Tragelementen bzw. -leisten lösbar befestigt sein, die außerhalb des Wirkungsbereiches liegen und kein Hindernis bilden können.Preferably, grate bars, which are bent in particular over about 150 °, to the Ends attachment extensions, which led out of the curvature area to the outside are. By means of the fastening extensions, the grate bars can be fixed to the machine Tragelements or strips are releasably attached, outside the Range of action and can not be an obstacle.
In einer weiteren bevorzugten Ausführung sind die Abstände zwischen den Roststäben wählbar, sodass die Korngröße des zu zerkleinernden Materials durch die Anzahl der montierten Roststäbe bestimmt ist. Die Befestigungsfortsätze weisen bevorzugt stirnseitig offene, hinterschnittene Nuten auf, in die hammerkopfartige Befestigungselemente, beispielsweise Gewindemuttern eingesetzt sind. An jeder maschinenfesten Tragleiste ist eine Lochreihe zur Aufnahme von Befestigungsschrauben vorgesehen, deren Lochabstand den minimal gewünschten Durchtrittsspalt vorgibt, wenn bei jedem Loch ein Roststab montiert wird. Für breitere Durchtrittsspalten bleiben zwischen den Roststäben ein oder mehrere Löcher frei.In a further preferred embodiment, the distances between the grate bars selectable, so that the grain size of the material to be shredded by the number of mounted grate bars is determined. The attachment extensions are preferred on the front side open, undercut grooves, in the hammerhead-like Fastening elements, such as threaded nuts are used. At every machine-fixed support bar is a row of holes for receiving Fixing screws provided whose hole spacing the minimum desired Passage gap dictates when a grate bar is mounted at each hole. For wider Passage gaps remain between the grate bars one or more holes free.
Die erfindungsgemäße Rostausbildung erübrigt auch aufwendige Einrichtungen, um den Rost bei Störungen auszuschwenken, wie es beim Stand der Technik üblich ist, sodass nicht nur der Rost, sondern auch die Zerkleinerungsmaschine einfacher aufgebaut ist.The rust formation according to the invention also eliminates the need for expensive facilities swing out the grill in the event of faults, as is customary in the prior art, so not only the rust, but also the crusher easier is constructed.
Die zueinander parallelen Roststäbe und die Durchtrittsspalte können sich in Umfangsrichtung erstrecken. In diesem Fall ist auch eine Ausführung möglich, in der die Hüllbahn des Rotors eine sägezahnartige Erzeugende aufweist, und die Roststäbe in zumindest zwei Scharen mit unterschiedlichen Abständen zur Rotorachse angeordnet sind. Eine derartige Ausbildung ist beispielsweise dann gegeben, wenn der Rotor quadratische Schneidwerkzeuge aufweist, deren Diagonalen radial zur Drehachse des Rotors verlaufen.The mutually parallel grate bars and the passage column can in Extend circumferential direction. In this case, an embodiment is possible in the the wrapping path of the rotor has a sawtooth-like generatrix, and the grate bars in at least two coulters with different distances to the rotor axis are arranged. Such training is given, for example, when the Rotor square cutting tools whose diagonal radially to Rotary axis of the rotor run.
In einer weiteren Ausführung können die Roststäbe und die Durchtrittsspalte fischgrätartig angeordnet sein. Durch die fischgrätartige Anordnung wird das Material zwar über die erste Hälfte des Materialauslasses axial in eine Richtung gedrückt, in der zweiten Hälfte jedoch wieder im selben Ausmaß zurückgedrückt, sodass die axiale Belastung der Vorrichtung gering bleibt, und eine scherende Wirkung nach beiden Seiten auftrittIn a further embodiment, the grate bars and the passage gaps be arranged like a herringbone. By herringbone arrangement, the material Although pressed axially over the first half of the material outlet in one direction, in the second half, however, pushed back to the same extent, so that the axial Loading of the device remains low, and a shearing effect after both Pages occurs

Eine erfindungsgemäße Zerkleinerungsmaschine weist ein Maschinengestell auf, in
dem unterhalb eines Fülltrichters 23 ein beispielsweise aus Trägerscheiben 3
aufgebauter Rotor 1 mit horizontaler Achse drehbar gelagert ist. Der Rotor 1 weist am
Umfang Halter 11 auf, an denen mittels Schrauben 15 Schneidzähne 12,
beispielsweise quadratische Wendeschneidhalter gehalten sind. Dem Rotor 1 ist am
unteren Ende des Fülltrichters 23 ein gehäusefestes Gegenmesser 20 mit einer dem
Schneidkantenverlauf des Rotors 1 angepassten Gegenschneidkante 21 zugeordnet,
auf den in Drehrichtung des Rotors 1 ein den Materialauslass 17 überspannender Rost
