Description

Die Erfindung betrifft eine Aufschließvorrichtung für Mischer oder vergleichbare Maschinen, welche einen im Behälter des Mischers befestigten Stator und einen gegenüber dem Stator bewegbaren Rotor aufweist, wobei an einer durch die Wand des Behälters ragenden, mit einem Antrieb verbundenen oder verbindbaren, drehbar gelagerten Welle des Rotors Aufschließwerkzeuge vorgesehen sind, welche mit am Stator befestigten weiteren Werkzeugen im Betrieb zusammenwirken.The invention relates to a disintegrating device for mixers or comparable machines, which has a stator fastened in the container of the mixer and a rotor which can be moved relative to the stator, with a rotatably mounted shaft of the rotor which projects through the wall of the container and is connected or connectable to a drive Unlocking tools are provided which interact with other tools attached to the stator during operation.

Eine vorbekannte Vorrichtung dieser Art weist am Rotor eine Scheibe auf, an der Stifte vorgesehen sind, die mit den Rotor umgebenden Teilen des Stators beim Umlauf der Scheibe zusammenwirken. Diese Vorrichtung hat sich zwar in der Praxis bewährt, ist jedoch für einige Mischgüter nicht ausreichend, weil insbesondere bei harten Mischgütern die Aufschließwirkung gelegentlich nicht ausreicht. Beim Aufschließen von Fasermaterial können sich im Mischgut sogar sogenannte Nester bilden, in denen das Mischgut überhaupt nicht oder zumindest unzureichend aufgeschlossen wird, und zwar selbst nach längeren Behandlungszeiten.A previously known device of this type has a disk on the rotor, on which pins are provided which interact with parts of the stator surrounding the rotor when the disk rotates. Although this device has proven itself in practice, it is not sufficient for some mixes, because the disintegration effect is sometimes insufficient, in particular in the case of hard mixes. When disintegrating fiber material, so-called nests can even form in the mix, in which the mix is not broken down at all or at least inadequately, even after longer treatment times.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Aufschließvorrichtung für den Einsatz in Mischern zu schaffen, die einfach und preiswert herzustellen und in ihrer Arbeitsweise äußerst wirksam ist, so daß innerhalb kürzester Betriebszeiten Mischgüter aller Art gut und gleichmäßig aufgeschlossen werden können.The invention has for its object to provide an improved digester for use in mixers, which is simple and inexpensive to manufacture and is extremely effective in its operation, so that mixed goods of all types can be digested well and evenly within the shortest operating times.

Diese Aufgabe wird erfindungsgemäß mit einer Aufschließvorrichtung gelöst, welche die Merkmale des Patentanspruches 1 aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.According to the invention, this object is achieved with a disintegrating device which has the features of patent claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Aufschließvorrichtung weist sowohl am Stator als auch am Rotor etwa radial verlaufende - beispielsweise messerförmige - Werkzeuge auf, die im Betrieb scherenartig, aber kontaktlos zusammenwirken, so daß auch harte, faserige und schwierig zu handhabende Materialien gut und intensiv aufgeschlossen werden können. Selbst bei der Verarbeitung von kurzen faserigen Mischgütern wird die Gefahr der Nesterbildung vermieden.The unlocking device according to the invention has both radially running - for example knife-shaped - tools on the stator as well as on the rotor, which work together like scissors but without contact, so that hard, fibrous and difficult to handle materials can be digested well and intensively. Even when processing short, fibrous mixes, the risk of nests forming is avoided.

Die miteinander zusammenwirkenden Teile des Stators und des Rotors sind einfach und preiswert herzustellen, da sie vorzugsweise jeweils platten- bzw. scheibenförmig ausgebildet sind und somit keine komplizierten Formen aufweisen. Die einzelnen Platten oder Scheiben der Vorrichtung lassen sich problemlos übereinander montieren, so daß auch eine mehrstufige oder mehrlagige Aufschließvorrichtung mit einfachen Mitteln und somit preiswert nach dem Baukastenprinzip hergestellt werden kann. Die messerartigen Werkzeuge von Stator und Rotor können, falls insbesonders harte Mischgüter zu verarbeiten sind, ohne Schwierigkeiten zusätzlich aufgepanzert sein.The interacting parts of the stator and of the rotor are simple and inexpensive to produce, since they are each preferably plate-shaped or disk-shaped and thus have no complicated shapes. The individual plates or disks of the device can be assembled one above the other without any problems, so that a multi-stage or multi-layer disintegration device can be manufactured with simple means and thus inexpensively according to the modular principle. The knife-like tools of the stator and rotor can, in particular if hard mixes are to be processed, be additionally armored without difficulty.

Die Scherspalte zwischen den Werkzeugen von Rotor und Stator lassen sich bei der erfindungsgemäßen Aufschließvorrichtung den aufzuschließenden Produkten anpassen, einfach dadurch, daß man zwischen die einzelnen Lagen von Stator und Rotor unterschiedlich dicke Distanzelement bzw. Distanzhalter einlegt, die sich außerhalb der Bereiche der miteinander zusammenwirkenden Aufschließ- oder Scherwerkzeuge befinden.The shear gaps between the tools of the rotor and stator can be adapted to the products to be unlocked in the unlocking device according to the invention, simply by inserting spacer elements or spacers of different thickness between the individual layers of the stator and rotor, which are located outside the areas of the interacting unlockers - or shaving tools.

Die Messer bzw. messerförmigen Werkzeuge des Stators können auch mit abgerundeten Kanten und auch als spitz auslaufende konische Körper ausgebildet sein. Insbesondere für das Aufschließen von Fasermaterial sind konische Messer bzw. Werkzeuge vorteilhaft, weil solche Werkzeuge Nester bzw. eine sogenannte Reiskornbildung vermeiden.The knives or knife-shaped tools of the stator can also be designed with rounded edges and also as a tapered conical body. Conical knives or tools are particularly advantageous for breaking up fiber material, because such tools avoid nests or so-called rice grain formation.

Die erfindungsgemäße Aufschließvorrichtung ist sozusagen ein Schersegmente aufweisender Dispergator.The digestion device according to the invention is, so to speak, a dispersant having shear segments.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Aufschließvorrichtung dargestellt, und zwar zeigt

  • Fig. 1 eine schaubildliche Ansicht der Aufschließvorrichtung von oben,
  • Fig. 2 eine ähnliche Ansicht der Aufschließvorrichtung wie in Fig. 1, wobei jedoch die Werkzeuge des Rotors weggelassen sind, und
  • Fig. 3 eine Einzelheit des Stators in schaubildlicher Ansicht.
In the drawing, an embodiment of the unlocking device according to the invention is shown, namely shows
  • 1 is a perspective view of the unlocking device from above,
  • Fig. 2 is a similar view of the unlocking device as in Fig. 1, but with the tools of the rotor omitted, and
  • Fig. 3 shows a detail of the stator in a diagrammatic view.

Die in der Zeichnung dargestellte Aufschließvorrichtung 1 weist einen Stator 2 und einen in diesem angeordneten und gegenüber demselben drehbaren Rotor 3 auf. Der Stator 2 ist auf einem Fuß 4 angeordnet, der an der Innenseite der Wand eines nicht näher dargestellten Mischbehälters zu befestigen ist.The unlocking device 1 shown in the drawing has a stator 2 and a rotor 3 arranged therein and rotatable relative thereto. The stator 2 is arranged on a foot 4 which is to be fastened to the inside of the wall of a mixing container (not shown in more detail).

Der Stator 2 besteht aus einer Anzahl von übereinander angeordneten plattenförmigen Scheiben 5, und zwar beim dargestellten Ausführungsbeispiel aus insgesamt vier Scheiben, zwischen denen jeweils Distanzringe 6 angeordnet sind. Dieses Paket aus Scheiben 5 und Distanzringen 6 ist mittels im Randbereich durch dieselben hindurchgesteckten Bolzen zusammengehalten, auf deren äußere Enden Kopfmuttern 7 aufgeschraubt sind. Die Bolzen selbst sind in der Zeichnung nicht erkennbar, da sie von den Scheiben 5, den Distanzringen 6 und den Kopfmuttern 7 verdeckt sind.The stator 2 consists of a number of plate-shaped disks 5 arranged one above the other, in the exemplary embodiment shown consisting of a total of four disks, between which spacer rings 6 are arranged in each case. This package of disks 5 and spacer rings 6 is held together by bolts inserted through them in the edge area, and head nuts 7 are screwed onto their outer ends. The bolts themselves cannot be seen in the drawing, since they are covered by the disks 5, the spacer rings 6 and the head nuts 7.

Die einzelnen Scheiben 5 haben einen äußeren ringförmigen Körper 8, von dem radial nach innen eine Anzahl von im Grundriß hier etwa rechteckigen Zungen 9 ausgeht, die zum Zentrum der betreffenden Scheiben weisen, jedoch im Abstand von diesem Zentrum enden, so daß sich im mittleren Bereich jeder Scheibe 5 ein freier Raum 10 befindet.The individual disks 5 have an outer annular body 8, from which radially inward a number of tongues 9, which are roughly rectangular in plan, extend to the center of the disks in question, but end at a distance from this center, so that in the middle Area of each disc 5 is a free space 10.

Im Zentrum des Stators 2 befindet sich eine koaxial zu diesem angordnete Welle 11, welche Teil des Rotors 3 bildet und die Wand des nicht dargestellten Mischbehälters durchsetzt. Auf der Außenseite des Mischbehälters ist die Welle in hier nicht dargestellter, jedoch an sich bekannter Weise drehbar gelagert und mit einem ebenfalls nicht dargestellten Antrieb verbunden.In the center of the stator 2 there is a shaft 11 arranged coaxially to the stator, which forms part of the rotor 3 and passes through the wall of the mixing container (not shown). On the outside of the mixing container, the shaft is rotatably supported in a manner which is not shown here but is known per se and is connected to a drive which is also not shown.

Auf der Welle 11 sind - hier sternförmig ausgebildete - Zerkleinerer 12 drehfest angeordnet, die mit zur Welle etwa tangential verlaufenden radialen Armer 13 zwischen die Zungen 9 von jeweils zwei unmittelbar übereinander angeordneten Scheiben 5 ragen, so daß die Zerkleinerer 12 in Höhe der Distanzringe 6 des Stators angeordnet sind. Da beim dargestellten Ausführungsbeispiel der Stator 2 vier Scheiben 5 und somit drei Distanzringe 6 aufweist, sind an der Welle 11 des Rotors 3 ebenfalls drei Zerkleinerer 12 befestigt. Diese Zerkleinerer 12 sind mittels nicht dargestellter Distanzscheiben im notwendigen axialen Abstand voneinander gehalten. Eine auf das äußere Ende der Welle 11 aufgeschraubte Kopfmutter 14 hält die Teile des Rotors 3 zusammen. Die Anzahl der Scheiben 5 und Zerkleinerer 12 ist jedoch variabel, weil die Aufschließvorrichtung 1 nach dem Baukastenprinzip aufbaubar und ausbaubar ist.On the shaft 11 - here star-shaped - shredders 12 are arranged in a rotationally fixed manner, which project with radial arms 13 which are approximately tangential to the shaft between the tongues 9 of two disks 5 arranged directly one above the other, so that the shredders 12 at the height of the spacer rings 6 Stator are arranged. Since in the illustrated embodiment the stator 2 has four disks 5 and thus three spacer rings 6, three shredders 12 are also attached to the shaft 11 of the rotor 3. These shredders 12 are kept at the necessary axial distance from one another by means of spacers, not shown. A head nut 14 screwed onto the outer end of the shaft 11 holds the parts of the rotor 3 together. The number of disks 5 and shredder 12 is variable, however, because the unlocking device 1 can be assembled and removed on the modular principle.

Es ist erkennbar, daß hier sowohl der Stator 2 als auch der Rotor 3 weitgehend aus plattenförmig ausgebildeten bzw. ebenen Teilen aufgebaut ist, die aus Metallplatten ausgestanzt werden können. Die Arme 13 der sternförmigen Zerkleinerer 12 des Rotors 3 wirken mit den radial nach innen vorstehenden Zungen 9 der Scheiben 5 des Stators 2 scherenförmig zusammen, wenn der Rotor 3 angetrieben wird.It can be seen that both the stator 2 and the rotor 3 are largely constructed from plate-shaped or flat parts which can be punched out of metal plates. The arms 13 of the star-shaped shredders 12 of the rotor 3 interact with the radially inwardly projecting tongues 9 of the disks 5 of the stator 2 when the rotor 3 is driven.

Da der Rotor 3 mit hoher Geschwindigkeit angetrieben werden kann, wird das zur Aufschließvorrichtung 1 gelangende Material bzw. Mischgut in den Bereich der als Aufschließwerkzeuge zusammenwirkenden Zungen 9 und Arme 13 geworfen und dann von den Werkzeugen der Aufschließvorrichtung 1 schnell, intensiv und gleichmäßig aufgeschlossen.Since the rotor 3 can be driven at high speed, the material or mixed material reaching the unlocking device 1 is thrown into the area of the tongues 9 and arms 13 interacting as unlocking tools and then quickly, intensively and uniformly unlocked by the tools of the unlocking device 1.

Obwohl beim dargestellten Ausführungsbeispiel der Aufschließvorrichtung 1 die nach innen ragenden Zungen 9 der übereinander angeordneten Scheiben 5 des Stators 2 und die etwa radial nach außen verlaufenden Arme 13 der sternförmigen Zerkleinerer 12 des Rotors 3 paktisch senkrecht übereinander angeordnet sind, können die Zungen 9 des Stators 2 und/oder die Arme 13 des Rotors 3 in den verschiedenen Ebenen der Aufschließvorrichtung 1 auch gegeneinander versetzt angeordnet werden, wenn dies für bestimmte Aufschließprobleme vorteilhaft sein sollte.Although in the illustrated embodiment of the unlocking device 1 the inwardly projecting tongues 9 of the disks 5 of the stator 2 arranged one above the other and the approximately radially outwardly extending arms 13 of the star-shaped shredder 12 of the rotor 3 are arranged vertically one above the other, the tongues 9 of the stator 2 and / or the arms 13 of the rotor 3 can also be arranged offset in relation to one another in the different planes of the unlocking device 1 if this should be advantageous for certain unlocking problems.

Beim dargestellten Ausführungsbeispiel sind die Scheiben 5 des Stators 2 aus Stahlblech ausgeschnitten bzw. ausgestanzt, so daß der ringförmige Körper 8 und die daran angeordneten, nach innen weisenden Zungen 9 einstückig ausgebildet sind und in einer Ebene liegen. Auch die sternförmigen Zerkleinerer 12 des Rotors 3 sind aus Stahlblech ausgeschnitten bzw. ausgestanzt, so daß deren radial bzw. in diesem Fall etwa tangential zur Welle 11 verlaufende Arme 13 in einer Ebene angeordnet sind. Sowohl die Scheiben 5 als auch die sternförmigen Zerkleinerer 12 können dabei aus gleichem Material, nämlich Stahlblech, gebildet sein und können auch gleich Dicke aufweisen.In the illustrated embodiment, the washers 5 of the stator 2 are cut or stamped out of sheet steel, so that the annular body 8 and the inwardly directed tongues 9 arranged thereon are formed in one piece and lie in one plane. The star-shaped shredders 12 of the rotor 3 are cut out or stamped out of sheet steel, so that their arms 13, which run radially or in this case approximately tangentially to the shaft 11, are arranged in one plane. Both the disks 5 and the star-shaped shredder 12 can be made of the same material, namely sheet steel, and can also have the same thickness.

Die Distanzringe 6 des Stators 2 und die in der Zeichnung nicht erkennbaren Distanzscheiben des Rotors 3 können ebenfalls aus Stahlblech, aber auch aus anderem Material bestehen. Es können je nach der gewünschten Weite der einzelnen Scherspalte Distanzringe und Distanzscheiben unterschiedlicher Dicke eingebaut werden, jedoch ist deren Dicke in jedem Falle wenigstens etwas größer als die Dicke der Scheiben 5 und der sternförmigen Zerkleinerer 12, damit der Rotor 3 so gegenüber dem Stator 2 eingerichtet werden kann, daß seine Arme 13 beim Umlauf nicht mit den Zungen 9 in Kontakt treten bzw. die Zungen nicht berühren können. Die die Werkzeuge der Aufschließvorrichtung 1 bildenden Zungen 9 und Arme 13 wirken zwar scherenartig miteinander zusammen, jedoch ist das Zusammenwirken kontaktlos, so daß die Drehbewegungen des vorzugsweise hochtourig angetriebenen Rotors 3 durch Kontakt mit dem Stator 2 nicht gehemmt werden können. Dadurch ist ein gleichförmiges und im Endergebnis auch schonendes Aufschließen der Mischgüter oder sonstigen Materialien gewährleistet.The spacer rings 6 of the stator 2 and the spacers of the rotor 3, which are not recognizable in the drawing, can likewise be made of sheet steel, but also of other material. Depending on the desired width of the individual shear gaps, spacer rings and spacer disks of different thicknesses can be installed, but their thickness is in any case at least somewhat greater than the thickness of the disks 5 and the star-shaped shredder 12, so that the rotor 3 is set up in relation to the stator 2 can be that his arms 13 do not come into contact with the tongues 9 or touch the tongues during circulation. The tongues 9 and arms 13 forming the tools of the unlocking device 1 interact with one another like scissors, but the interaction is contactless, so that the rotary movements of the rotor 3, which is preferably driven at high speed, cannot be inhibited by contact with the stator 2. This ensures a uniform and, in the end, gentle disintegration of the mix or other materials.

Andererseits wird auch wirksam vermieden, daß die Teile des Rotors 3 und des Stators 2 sich gegenseitig abreiben und damit verschleißen können. Daher gelangt auch kein Abrieb von den gegeneinander bewegten Teilen der Aufschließvorrichtung 1 in das behandelte Material, was höchst unerwünscht wäre. Da die Distanzringe 6 des Stators 2 und die Distanzscheiben oder Distanzbuchsen des Rotors 3 auswechselbar sind, lassen sich auf die jeweiligen Mischgüter abgestimmte Scherspalte beliebiger Weite leicht einstellen. Für ein eventuell erwünschtes Umrüsten oder Nachrüsten beim Betreiber braucht man lediglich die Kopfmuttern 7 des Stators 2 und die Kopfmutter 14 der Welle 11 des Rotors 3 zu lösen.On the other hand, it is also effectively avoided that the parts of the rotor 3 and the stator 2 rub against one another and can therefore wear out. Therefore, no abrasion gets into the treated material from the parts of the unlocking device 1 that are moving against one another, which would be highly undesirable. Since the spacer rings 6 of the stator 2 and the spacers or spacer bushes of the rotor 3 are interchangeable, shear gaps of any width matched to the respective mix can be easily adjusted. For a possibly desired retooling or retrofitting at the operator, one only needs to loosen the head nuts 7 of the stator 2 and the head nut 14 of the shaft 11 of the rotor 3.

Bei der dargestellten Ausführungsform der Aufschließvorrichtung sind die als Aufschließ- oder Scherwerkzeuge dienenden Zungen 9 und Arme 13 scharfkantig bzw. eckig ausgebildet. Sie können aber auch in Arbeitsrichtung schneidenartig zulaufen, ebenso wie die Arme des Rotors konisch ausgebildet sein oder nach außen spitz zulaufen können.In the embodiment of the unlocking device shown, the tongues 9 and arms 13 serving as unlocking or shearing tools are sharp-edged or angular. But they can also taper in the direction of the cut, as can the arms of the rotor be formed or taper to the outside.

In der Zeichnung sind als Distanzelemente zwischen den Scheiben 5 des Stators 2 ununterbrochene Distanzringe 6 gezeigt. Dadurch ergeben sich innerhalb des Stators nach außen geschlossene Scherebenen. Anstelle ununterbrochener umlaufender Distanzringe können als Distanzelemente auch einzelne Ringsegmente oder auch einzelne Distanzbuchsen eingebaut werden, wodurch man im Stator teilweise offene bzw. ganz offene Scherebene erhält.In the drawing, uninterrupted spacer rings 6 are shown as spacer elements between the disks 5 of the stator 2. This results in closed shear planes inside the stator. Instead of continuous circumferential spacer rings, individual ring segments or individual spacer bushes can also be installed as spacer elements, as a result of which partially open or completely open shear planes are obtained in the stator.

Die Distanzelemte oder Distanzhalter wie Distanzringe, Distanzringsegmente oder Distanzbuchsen können separate Bauteile sein, wie die Distanzringe 6, jedoch ist es auch möglich, diese Distanzelemente jeweils mit den Scheiben 5 des Stators 2, die sie auseinanderhalten sollen, ieinstückig zu verbinden. Im letztgenannten Falle lassen sich die einzelnen Scheiben 5 des Stators 2 mit den betreffenden Distanzelementen einstückig fertigen, wobei es möglich ist, jede Scheibe auf einer Seite mit entsprechenden Distanzelementen zu versehen oder jeweils jede zweite Scheibe auf beiden Seiten mit Distanzelementen ausstatten, während dann die übrigen Scheiben flache Stanzkörper wie die in der Zeichnung gezeigten Scheiben 5 sein können.The spacer elements or spacers such as spacer rings, spacer ring segments or spacer bushes can be separate components, such as the spacer rings 6, but it is also possible to connect these spacer elements to the disks 5 of the stator 2, which are intended to keep them apart, in one piece. In the latter case, the individual disks 5 of the stator 2 can be manufactured in one piece with the relevant spacer elements, it being possible to provide each disk on one side with corresponding spacer elements or to equip every second disk on both sides with spacer elements, while the others Disks flat punched bodies can be like the disks 5 shown in the drawing.

Die Distanzringe 6 oder entsprechende Ringsegmente können an der Innenseite glatt, rauh, gewellt oder gezahnt sein. Im Falle der aufgerauhten, gewellt oder gezahnten Ausbildung der Innenseite der Distanzelemente tragen die ringförmigen oder teilringförmigen Distanzelemente zum Aufschließvorgang zumindest begrenzt bei.The spacer rings 6 or corresponding ring segments can be smooth, rough, corrugated or toothed on the inside. In the case of the roughened, corrugated or toothed design of the inside of the spacer elements, the annular or partially annular spacer elements contribute at least to a limited extent to the unlocking process.

Die Scherelemente der Scheiben 5 des Stators 2 können, wie in der Zeichnung gezeigt, als Zungen 9 mit glatten Enden ausgebildet sein, jedoch lassen sich die nach innen weisenden Enden der zungenförmigen Scherelemente auch abgerundet ausbilden, ebenso wie die Scherelemente nach innen spitz zulaufen können.The shear elements of the disks 5 of the stator 2 can, as shown in the drawing, be designed as tongues 9 with smooth ends, but the inwardly facing ends of the tongue-shaped shear elements can also be rounded off, just as the shear elements can taper inwards.

Die Arme 13 des Rotors 3 können in gleicher Weise am nach außen weisenden Ende glatt, abgerundet oder spitz zulaufend ausgebildet sein. Auch können die Arme des Rotors messerartig oder stabförmig ausgebildet sein.The arms 13 of the rotor 3 can in the same way be smooth, rounded or tapered at the outward end. The arms of the rotor can also be knife-like or rod-shaped.

Die Dicke der Zungen 9 des Stators 2 kann ebenso wie die Dicke der Arme 13 des Rotors 3 zum jeweils äußeren Ende geringer werden, so daß der Scherspalt über seine radiale Länge nur dann gleichförmige Weite aufweist, wenn die Dickenverringerung der miteinander zusammenwirkenden Zungen 9 und Arme 13 gleichförmig ist. Bei unterschiedlicherThe thickness of the tongues 9 of the stator 2, like the thickness of the arms 13 of the rotor 3, can decrease towards the outer end, so that the shear gap has a uniform width over its radial length only when the thickness of the interacting tongues 9 and arms is reduced 13 is uniform. With different

Dickenveränderung der miteiander zusammenwirkenden Scherelemente erhält man hingegen in radialer Richtung eine Verengung oder Erweiterung des Scherspaltes.On the other hand, changes in the thickness of the shear elements interacting with one another result in a narrowing or widening of the shear gap in the radial direction.

Die Dicke der Zungen 9 des Stators 2 und gegebenenfalls auch die Dicke der Arme 13 des Rotors 3 kann in horizontaler Richtung bzw. innerhalb einer Ebene variieren, so daß diese Scherelemente einen etwa keilförmigen Querschnitt aufweisen. Dadurch ergibt sich in tangentialer Richtung eine Verengung des Scherspaltes, wobei es zweckmäßig ist, daß der dünnere Abschnitt des keilförmigen Querschnittes dieser Scherelemente in Arbeitsrichtung gesehen nach vorne weist, damit der Scherspalt sich in Arbeitsrichtung verengt und somit auf das aufzuschließende Gut noch besser aufschließend einwirkt.The thickness of the tongues 9 of the stator 2 and possibly also the thickness of the arms 13 of the rotor 3 can vary in the horizontal direction or within one plane, so that these shear elements have an approximately wedge-shaped cross section. This results in a narrowing of the shear gap in the tangential direction, it being expedient that the thinner section of the wedge-shaped cross-section of these shear elements points forward in the working direction, so that the shear gap narrows in the working direction and thus has an even better effect on the material to be broken down.

Obwohl in der Zeichnung die als Scherelemente des Stators dienenden Zungen 9 einstückig mit den betreffenden Scheiben 5 des Rotors 2 gezeigt sind, können diese Scherelemente auch, insbesondere wenn sie stabförmige Elemente sind, durch Verschrauben, durch Steckverbindung oder in ähnlicher Weise an dem ringförmigen Körper 8 der Scheiben 5 des Stators 2 befestigt werden. Dann lassen sich diese Scherelemente auswechseln, beispielsweise wenn sie verschlissen sind, ebenso wie man sie aus anderem Material als die sie haltenden Scheiben 5 herstellen kann.Although the tongues 9 serving as shear elements of the stator are shown in the drawing in one piece with the respective disks 5 of the rotor 2, these shear elements can also be attached to the annular body 8, in particular if they are rod-shaped elements, by screwing, by plug connection or in a similar manner the discs 5 of the stator 2 are attached. Then these shear elements can be exchanged, for example if they are worn out, just as they can be made of a different material than the disks 5 holding them.

Unterhalb der ersten und oberhalb der letzten Ebene des Stators 2 können am Rotor 3 zusätzliche Messer oder flügelartige Rotorelemente angebracht sein. Dadurch erhält man im Bereich der Aufschließvorrichtung 1 eine stärkere axiale Förderung des aufzuschließenden Gutes, ebenso wie mögliche Stauungen des Gutes schnell und gleichförmig aufgelöst werden.Additional knives or wing-like rotor elements can be attached to the rotor 3 below the first and above the last level of the stator 2. This results in a stronger axial conveyance of the material to be unlocked in the area of the unlocking device 1, as well as possible congestion of the material being quickly and uniformly resolved.
