Aus der DE 34 10 053 A1 ist eine Zerkleinerungsmaschine für Müll bekannt, die zwei Paar von Brechwalzen umfaßt, wobei die Wellen eines jeden Paares gegensinnig laufen. Die Brechwalzen eines jeden Paares weichen in der Geometrie voneinander ab. Bei einer Recyclinganlage zur Granulaterzeugung sind nach der DE 37 23 038 in drei Ebenen insgesamt vier Paare von Messerwerken mit voneinander abweichender Geometrie angeordnet.From DE 34 10 053 A1 a grinding machine for waste is known, the two Pair of crushing rollers comprises, the waves of each pair run in opposite directions. The crushing rollers of each pair differ in their geometry. At A recycling plant for the production of granules are in three according to DE 37 23 038 Levels a total of four pairs of knife units with different geometries arranged.
Bei einer weiteren Zerkleinerungsmaschine nach der DE 27 02 177 A1 sind in einem Gehäuse in parallel zueinander verlaufenden Ebenen jeweils ein Paar von Walzen angeordnet, die gegensinnig und mit unterschiedlichen Drehgeschwindigkeiten laufen. Dabei weist jede Walze Reißzähne mit rückwärtsgerichteter Haltmetallbestückung auf.In another shredding machine according to DE 27 02 177 A1 are in one Housing in parallel planes each have a pair of rollers arranged, which run in opposite directions and at different speeds. Each roller has fangs with rear-facing metal fittings.
Der vorliegenden Erfindung liegt das Problem zugrunde, einen Shredder der eingangs genannten Art so weiterzubilden, daß dieser betriebssicher und für einen großen Bereich von Materialien wirksam und relativ einfach in der Konstruktion ist.The present invention is based on the problem of a shredder at the outset mentioned type so that it is reliable and for a large area of materials is effective and relatively simple in construction.
Das Problem wird erfindungsgemäß dadurch gelöst, daß die von der Welle ausgehenden Zerkleinerungselemente flachquaderförmige Stäbe sind, wobei jeweils zwei diametral zu der Welle verlaufende Zerkleinerungselemente Abschnitte eines der von der Welle durchsetzten flachquaderförmigen Stabs sind. Insbesondere ist vorgesehen, daß die von der Welle ausgehenden Zerkleinerungselemente in Längsrichtung der Welle betrachtet fluchtend zueinander verlaufen und eine einzige Linie oder ein vorzugsweise rechtwinkliges Kreuz bilden. Nach einer hervorzuhebenden Ausgestaltung sieht die Erfindung des weiteren vor, daß drei Paare von Wellen übereinander angeordnet sind, wobei zumindest die Wellen eines Paares gleichsinnig mit voneinander abweichender Umdrehungsgeschwindigkeit laufen, wobei vorzugsweise beide benachbarten Paare von Wellen gegensinnig laufen.The problem is solved according to the invention in that the outgoing from the shaft Crushing elements are flat cuboid bars, two diametrically each the shaft-running shredding elements sections of one of the shaft interspersed flat cuboid rods. In particular, it is provided that the shredding elements emerging from the shaft are viewed in the longitudinal direction of the shaft run in alignment with each other and a single line or a preferably rectangular one Form a cross. The invention provides for an embodiment to be emphasized furthermore that three pairs of shafts are arranged one above the other, whereby at least the waves of a pair in the same direction with different ones Rotation speed run, preferably both adjacent pairs of Waves run in opposite directions.
Durch die erfindungsgemäße Lehre wird das Material, das zerkleinert werden soll, sukzessiv durch Paare von teils gegensinnig, teils gleichsinnig laufenden und teilweise ineinander greifenden Zerkleinerungselementen in Form von Stabelementen durch den Shredder hindurchgezogen. Dabei weisen die Zerkleinerungselemente Schneiden im eigentlichen Sinne nicht auf, um das Material zu zerkleinern. Vielmehr erfolgt ein Auseinanderscheren, wobei beim Hindurchziehen durch den Shredder das Material sukzessiv zu kleineren Teilen geshreddert wird. Dabei wird das Material insbesondere durch die vorzugsweise in der zweiten Zerkleinerungsstufe gleichsinnig, jedoch mit unterschiedlichen Drehgeschwindigkeiten laufenden Wellen stark mechanisch belastet, wodurch ein Zerkleinern auch schwer zerreißbarer Materialien ermöglicht wird.Through the teaching of the invention, the material that is to be crushed is successively through pairs of partly in opposite directions, partly in the same direction and partly intermeshing shredding elements in the form of rod elements by the Shredder pulled through. The shredding elements have cutting edges proper sense to shred the material. Rather, one takes place Shear apart, pulling the material through the shredder is gradually shredded into smaller parts. The material in particular through the same direction, preferably in the second size reduction stage, but with shafts running at different speeds are subjected to high mechanical loads, which enables materials that are difficult to tear to be shredded.
Eine hohe Effizienz hat sich dann gezeigt, wenn der Shredder drei Wellenpaare umfaßt, so daß das Material drei Zerkleinerungsstufen durchläuft. Selbstverständlich kann die Anzahl der Paare aber auch größer oder kleiner sein. Losgelöst hiervon sollten jedoch die Wellen eines jeden Paares voneinander abweichende Umdrehungsgeschwindigkeiten aufweisen.A high efficiency has been shown when the shredder comprises three pairs of waves, so that the material goes through three shredding stages. Of course, the The number of pairs can also be larger or smaller. Detached from this, however the shafts of each pair have different rotational speeds exhibit.
Dadurch, daß die Zerkleinerungselemente eine Stab- also Quaderform aufweisen, können die Stäbe aus Stahlblechen zum Beispiel durch Brennschneiden hergestellt werden, wobei - abweichend vom vorbekannten Stand der Technik - eine zusätzliche Schneidkante nicht ausgebildet werden muß; denn die Zerkleinerungselemente weisen aufgrund der Quaderform plane Längsseiten auf, die senkrecht zur Umdrehungsrichtung verlaufen.Because the shredding elements have a rod-like cuboid shape, the bars can be made from sheet steel, for example by flame cutting be, whereby - in deviation from the known prior art - an additional Cutting edge does not have to be formed; because the shredding elements point Due to the cuboid shape, the long sides are flat and perpendicular to the direction of rotation run.
Um ein sicheres Befestigen der als Flachquaderelemente zu bezeichnenden Stabelemente zu ermöglichen, ist vorgesehen, daß die vorzugsweise auf eine Sechskantwelle aufschiebbaren Stabelemente jeweils einen von zur Drehrichtung abgewandter Längsseite ausgehenden Schlitz aufweisen, der sich bis zur Bohrung hin, die von der Welle durchsetzt wird, erstreckt. Über Spann- wie Schraubelemente, die innerhalb des Stabelementes verlaufen, kann sodann die Schlitzbreite verringert werden, wodurch das gewünschte Festklemmen auf der Welle erfolgt. To securely fasten the rod elements, which are referred to as flat cuboid elements To enable, it is provided that those which can preferably be pushed onto a hexagonal shaft Rod elements each have a longitudinal side facing away from the direction of rotation have outgoing slot, which extends to the hole penetrated by the shaft is extended. Via tensioning and screwing elements that are inside the bar element then the slot width can be reduced, whereby the desired Clamping takes place on the shaft.
Drei Paare von Wellen, d.h. sechs Wellen insgesamt können von zwei Motoren angetrieben werden, die vorzugsweise auf der gegenüberliegenden Seite des Gehäuses angeordnet sind, wobei ein Motor vier Wellen und der andere zwei Wellen mittels Riemen oder gleichwirkende Elemente antreibt, die derart verlaufen, daß die gewünschte Drehrichtung und Drehgeschwindigkeit erzielbar ist. Dabei sollten die Wellen eines jeden Paares voneinander abweichende Umdrehungsgeschwindigkeiten aufweisen.Three pairs of waves, i.e. six shafts in total can be driven by two motors be preferably on the opposite side of the housing are arranged, one motor using four shafts and the other using two shafts Drive belt or equivalent elements that run such that the desired Direction of rotation and speed of rotation can be achieved. The waves should be one each pair have different rotational speeds.
Insbesondere zeichnet sich ein Shredder mit zumindest drei Paaren von Wellen mit von diesen abragenden Zerreißelementen, wobei jedes Paar in einer von vorzugsweise horizontal und parallel zueinander verlaufenden Ebenen angeordnet ist, und wobei zumindest die Wellen eines Paares gegensinnig laufen und zumindest die Wellen eines weiteren und/oder des Paares voneinander abweichende Umdrehungsgeschwindigkeiten aufweisen, dadurch aus, daß die von der Welle ausgehenden Zerkleinerungselemente im Schnitt eine Rechteckform aufweisende Stabelemente sind, daß jeweils zwei diametral zu der Welle verlaufende Zerkleinerungselemente Abschnitte eines der von der Welle durchsetzten Stabelemente sind, daß die Welle eines zwischen einem oberen und einem unteren Wellenpaar angeordneten Paares in gleichsinnig, jedoch voneinander abweichende Umdrehungsgeschwindigkeiten und die benachbarten Paare von Wellen gegensinnig antreibbar sind.In particular, a shredder with at least three pairs of waves is characterized by these protruding tearing elements, each pair in one of preferably is arranged horizontally and parallel to each other, and wherein at least the waves of a couple run in opposite directions and at least the waves of one further and / or the pair of different rotational speeds have, characterized in that the starting from the shaft crushing elements in Section elements having a rectangular shape are that each two diametrically Crushing elements running to the shaft Sections of one of the shaft penetrated rod elements are that the shaft one between an upper and a lower pair of waves arranged in the same direction, but different Rotational speeds and the adjacent pairs of shafts in opposite directions are drivable.
Nach einer Weiterbildung der Erfindung ist vorgesehen, daß jeweils ein Paar von Wellen von einem Rahmen aufgenommen ist, der mit dem Gehäuse oder entsprechenden Rahmen des Shredders lösbar verbunden ist. Hierdurch ergibt sich ein modularer Aufbau. Insbesondere ist jedoch vorgesehen, daß das Gehäuse aus modular zusammengesetzten Abschnitten besteht, in deren Trennflächen die Wellen jeweils eines Paares gelagert sind. Hierdurch ergibt sich der Vorteil, daß nach Entfernen eines Gehäuseabschnittes die Wellen frei zugänglich sind, um zum Beispiel unmittelbar vor Ort ausgetauscht bzw. gewartet zu werden. According to a development of the invention it is provided that a pair of Shafts are received by a frame that is attached to the housing or equivalent Frame of the shredder is detachably connected. This results in a modular Construction. In particular, however, it is provided that the housing is composed of modules Sections exists, in the dividing surfaces of which the waves of a pair are stored. This has the advantage that after removing a housing section the waves are freely accessible, for example, exchanged directly on site or to be serviced.

In Fig. 1 ist eine perspektivische Darstellung des Shredders dargestellt, von dem eine
Wandung 2 des Gehäuses 4 weggelassen ist. Innerhalb des Gehäuses 4 befinden sich
drei Paare von Wellen 6, die aus Gründen größerer Klarheit als vordere obere Welle
7, vordere mittlere Welle 8, vordere bodenseitige Welle 9, hintere obere Welle 10,
hintere mittlere Welle 11 und hintere bodenseitige Welle 12 bezeichnet sind. Unter Bezugnahme
auf die Fig. 2, 5 und 6 wird unter "vordere" als von Motoren 14, 15 entfernt
verstanden, d.h. daß die Motoren 14 und 15 rückseitig am Shredder angeordnet sind.In Fig. 1, a perspective view of the shredder is shown, one of which
Die oberen vier Wellen weisen einen Durchmesser von 3 inch (ca. 7,6 cm), die unteren zwei Wellen einen Durchmesser von 2,5 inch (ca. 6,4 cm) auf. Sobald das Material die Schneiden der beiden bodenseitigen Wellen erreicht, ist dieses bereits wesentlich in die Stückgrößen zerkleinert, so daß ein kleinerer Wellendurchmesser möglich ist. Die Schneiden oder Messer der zwei bodenseitigen Wellen müssen nicht so viel Arbeit wie die oberen Wellen verrichten und brauchen daher nicht ganz so fest zu sein.The upper four shafts have a diameter of 3 inches (approx. 7.6 cm), the lower ones two shafts with a diameter of 2.5 inches (approx. 6.4 cm). Once the material is the Cutting the two bottom-side waves reached, this is already essential in the Shredded piece sizes so that a smaller shaft diameter is possible. The Cutting or knife the two bottom shafts don't need as much work as the upper waves perform and therefore do not need to be quite as firm.
An jedem Schaft sind viele Schneidmesser oder -blätter angeschweißt. Die Messer bestehen aus irgendeinem geeigneten gehärteten Metall. Bevorzugterweise handelt es sich hierbei z.B. um QT100-Stahl. Die Messer sind mit ihren langen rechtwinkligen Formen durch Brennschneiden hergestellt und vorgebohrt, um an die Wellendurchmesser angepaßt zu sein, und werden dann mit denselben verschweißt. Wie insbesondere den Fig. 1 und 4 zu entnehmen ist, greifen die Schneiden ineinander ein. Jedoch greifen diese nicht immer in der in Fig. 4 gezeigten relativen Position ineinander ein, da unterschiedliche Drehgeschwindigkeiten herrschen, wie nachstehend erläutert wird.Many cutting knives or blades are welded to each shaft. The knife are made of any suitable hardened metal. It is preferably e.g. around QT100 steel. The knives are rectangular with their long ones Forms made by flame cutting and pre-drilled to match the shaft diameter to be adapted, and are then welded to the same. How in particular 1 and 4 can be seen, the cutting edges engage in one another. However they do not always interlock in the relative position shown in FIG. 4, since there are different rotational speeds, as explained below.
Wie der Fig. 2 entnommen werden kann, sind zwei Motoren 14 und 15 vorhanden, die
an beiden Seiten des Shredders angeordnet sind. Der Motor 14 treibt vier der Wellen
mittels drei Gurten 18 an, die um Scheiben 20 um die Motorantriebswelle und den vier
Shredderwellen geführt sind. Der Motor 15 treibt ähnlich die zwei weiteren Wellen über
drei Gurte 18 an. Wie aus Fig. 5 erkennbar ist, werden die Gurte oder Riemen des
Motors 14 zuerst unter den Scheiben der vorderen bodenseitigen Welle 9, dann rückwärts
und unter den Scheiben an der hinteren mittleren Welle 11, dann abwärts und
vorwärts unter den Scheiben an der vorderen mittleren Welle 8 und dann nach oben
über Scheiben an der vorderen oberen Welle 7 und zurück zum Motor geführt.As can be seen in FIG. 2, there are two
Wie aus Fig. 6 erkennbar wird, werden die Riemen vom Motor 15 zunächst unter die
Scheiben der hinteren bodenseitigen Welle 12, dann aufwärts und über Scheiben an der
hinteren oberen Welle 10 und zurück zum Motor geführt.As can be seen from Fig. 6, the belts of the
Somit gilt für jedes Paar von Wellen, daß die Schneiden gegeneinander und abwärts gedreht werden, um das Material durch den Shredder zu ziehen.Thus, for each pair of shafts, the cutting edges face each other and downwards be rotated to pull the material through the shredder.
Beide Motoren haben Riemenscheiben mit 6 1/4 inch (ca. 15,9 cm) Durchmesser. Die
Riemenscheibe an der vorderen oberen Welle 7, der hinteren mittleren Welle 11 und der
vorderen bodenseitigen Welle 9 weisen einen Durchmesser von 9 1/4 inch (ca. 23,9 cm)
auf. Die Riemenscheiben der hinteren oberen Welle 10, der vorderen mittleren Welle 8
und der hinteren bodenseitigen Welle 12 haben einen Durchmesser von 8 1/4 inch (ca.
21,3 cm). Jeder Motor wird mit nahezu gleicher Geschwindigkeit betrieben, z.B. 1.750
Umdrehungen pro Minute.Both motors have pulleys with a 6 1/4 inch (approx. 15.9 cm) diameter. The
Pulley on the front
Somit sind in jedem Paar von Wellen (obere, mittlere und untere) eine Welle mit einer 8 1/4 inch (ca. 21,3 cm) Riemenscheibe und eine andere mit einer 9 1/4 inch (ca. 23,9 cm) Riemenscheibe vorhanden. Die Schneidmesser eines jeden Paares können sich daher mit unterschiedlichen Geschwindigkeiten drehen, so daß sie nicht zu jeder Zeit in derselben Position relativ zueinander eingreifen. Hierin ist ein Faktor zu sehen, der zu der extremen effektiven Funktion des Shredders führt.Thus, in each pair of waves (upper, middle and lower) there is a wave with one 8 1/4 inch (about 21.3 cm) pulley and another with a 9 1/4 inch (about 23.9 cm) pulley present. The cutting knives of each pair can be therefore rotate at different speeds so that they are not in at all times engage the same position relative to each other. Here is a factor to be seen the extremely effective function of the shredder.
Da der Motor 15 nur zwei Wellen und der Motor 14 vier Wellen antreibt, kann ersterer
schwächer ausgelegt sein. So kann z.B. der Motor 14 50 PS und der Motor 15 40 PS
haben. Bevorzugterweise werden Elektromotoren benutzt, doch ist es offensichtlich, daß
die Erfindung nicht auf irgendeinen bestimmten Motortyp beschränkt ist.Since the
Eine weitere bevorzugte Ausführungsform des Shredders ist der Fig. 7 zu entnehmen,
bei dem das Gehäuse aus drei Rahmen 19, 20, 21 besteht, die übereinander angeordnet
sind. Die drei Rahmen enthalten die Wellenpaare 7, 10 und 8, 11 und 9, 12 und sind
übereinander angeordnet. Die Rahmen mit ihren Wellenpaaren bilden jeweils ein Modul
mit den Lagern und Riemenscheiben. Hierdurch kann die Abschaltzeit bedingt durch das
Installieren eines neuen Moduls verkürzt werden im Vergleich zu der Zeit, die benötigt
wird, um das Modul selbst zu reparieren. Nachdem ein neues Modul montiert ist, kann
der Shredder unmittelbar wieder in Betrieb genommen werden. Das entfernte Modul
kann repariert und gewartet werden, ohne daß der Betrieb beeinflußt wird.A further preferred embodiment of the shredder can be seen in FIG. 7,
in which the housing consists of three
Wie die Fig. 7 des weiteren zeigt, sollte das Gehäuse derart modular aufgebaut sein, daß die Trennlinien zwischen den einzelnen Gehäuseteilen die Wellenpaare (7), (10) und (8), (11) und (9), (12) schneiden. Dies ist in Fig. 7 durch gestrichelte und mit Bezugszeichen (22), (23), (24) versehene Linien angedeutet. In diesem Fall besteht das Gehäuse bei drei übereinander angeordneten Paaren von Wellen aus nicht näher bezeichneten vier rahmenförmigen Abschnitten.As FIG. 7 further shows, the housing should have a modular structure, that the dividing lines between the individual housing parts the shaft pairs (7), (10) and (8), (11) and (9), (12) cut. This is in Fig. 7 by dashed and with Reference numerals (22), (23), (24) indicated lines. In this case there is Housing with three pairs of shafts arranged one above the other not closer designated four frame-shaped sections.
Ein entsprechender modularer Aufbau hat den Vorteil, daß beim Entfernen eines Gehäuseabschnitts unmittelbar ein Wellenpaar freigelegt wird, um gegebenenfalls ohne weitere aufwendige Arbeiten eine Wartung bzw. ein Austausch z. B. einer beschädigten Welle vornehmen zu können.A corresponding modular structure has the advantage that when a housing section is removed a pair of waves is immediately exposed, if necessary without further elaborate work a maintenance or an exchange z. B. a damaged shaft to be able to make.
In den Fig. 8 - 14 ist eine besonders hervorzuhebende Ausführungsform eines Shredders
25 dargestellt, der - wie die Ausführungsform der Fig. 1 - 6 zeigen - drei Paare von
Wellen 26, 27, 28, 29 und 30, 31 umfaßt, die in Wandungen 32, 33 eines Gehäuses des
Shredders 24 gelagert sind.8-14 is a particularly noteworthy embodiment of a
Wie die Seitendarstellungen der Fig. 8 und 11 verdeutlichen, können die Wellen 27, 28,
29 und 30 von einem nicht dargestellten ersten Motor bzw. von diesen ausgehenden
Riemen und die Wellen 26 und 30 von einem zweiten Motor angetrieben werden. Jede
Welle weist an einer Stirnseite eine Riemenscheibe 34, 35, 36, 37, 38, 39 auf, die zum
Teil unterschiedliche Durchmesser aufweisen. Hierdurch wird die erfindungsgemäße
Lehre realisiert, daß die Umdrehungsgeschwindigkeit eines jeden Paares von Wellen 26,
27 bzw. 28, 29 bzw. 30, 31 voneinander abweichen. Ferner besteht die Möglichkeit, daß
die Wellen 26 bis 31 derart angetrieben werden, daß zumindest das mittlere Wellenpaar
28, 29 gleichsinnig, wohingegen die angrenzenden Wellenpaare 26, 27 bzw. 30 und 31
gegensinnig laufen. Hierzu kann eine der mittleren Wellen 28, 29 über einen gesonderten
also dritten Motor angetrieben werden.As the side representations of FIGS. 8 and 11 illustrate, the
Von jeder Welle, von der in Fig. 12 rein beispielhaft die Welle 26 dargestellt ist, gehen
Stabelemente 40 aus, die eine Rechteckform und senkrecht zur Drehrichtung plane
Längsseiten aufweisen. Die Flachquaderelemente 40 weisen demzufolge sowohl in
Längsrichtung als auch in Querrichtung, also entlang der Linie 41 eine Rechteckgeometrie
auf. Die Zerreißelemente 40 sind durch Abstandselemente beabstandet zueinander
auf der Welle 26 angeordnet, die im Bereich der Zerreißelemente 40 eine Sechseckform
aufweisen kann.From each shaft, of which the
Um ein sicheres Festklemmen der Zerreißelemente 40 sicherzustellen, weisen diese von
der zur Drehrichtung abgewandten Längsseite 42 ausgehend einen Schlitz 43 auf, der
sich bis zur Bohrung 45 erstreckt, die von der Welle 26 durchsetzt wird. Im Bereich des
Schlitzes gehen von der Längsseite 42 innerhalb der Zerreißelemente 40 erstreckende
Schraubelemente 44 aus, um das Flachquaderelement 40 auf der Welle 26 in einem
Umfang festklemmen zu können, daß eine Unverrückbarkeit gegeben ist.In order to ensure that the tearing
Die von den einzelnen Wellen 26, 27, 28, 29, 30, 31 abragenden Zerreißelemente 40
verlaufen zueinander derart versetzt, daß die Zerreißelemente 40 eines jeden Wellenpaares
und zu dem benachbarten Paar von Wellen versetzt zueinander verlaufen. Ferner
bilden die Zerreißelemente 40 jeder Welle 26, 27, 28, 39, 30, 31 eine Umhüllende,
wobei die Umhüllenden der oberen Wellenpaare 26, 27 und 28, 29 sich durchdringen,
wohingegen die Umhüllenden der unteren Wellenpaare 28, 29 und 30, 31 beabstandet
zueinander verlaufen oder sich gerade berühren, wie insbesondere die Fig. 9 und 10 verdeutlichen.The tearing
Die Anordnungen haben sich als sehr effektiv für das Shreddern eines großen Bereichs von erfindungsgemäßen Materialien gezeigt, von Automobilteilen über Laufschuhe, Videobänder, Computer, Tastaturen, elektronische Teile allgemein, Spielzeug, Glas, Flaschen etc.. Diese Auflistung ist gewiß nicht enumerativ, da der Shredder ohne weiteres auf einen großen Bereich von Materialien auslegbar ist.The arrangements have proven to be very effective for shredding a large area of materials according to the invention, from automotive parts to running shoes, Videotapes, computers, keyboards, electronic parts in general, toys, glass, Bottles etc. This list is certainly not enumerative since the shredder is without can be designed for a wide range of materials.
