Description

Die Erfindung bezieht sich auf eine Vorrichtunq zum Fördern, zerkleinern und Mischen von Fördergut mit hohem Feststoffgehalt, mit einem zylindrischen Gehäuse und einem in dieses hineinragenden Wellenstumpf, einer letzteren gegenüberliegenden Eintrags- und mindestens einer senkrecht, annähernd senkrecht oder tangential zur Wellenstumpfachse vorgesehenen Austragsöffnung sowie am Wellenstumpf angebrachten, bis zur Eintragsöffnung reichenden Lamellen o.dgl.. Statt Lamellen können auch in Achsrichtung und/oder quer dazu gebogene Schaufeln verwendet werden.The invention relates to a device for conveying, comminuting and mixing conveyed material with a high solids content, with a cylindrical housing and a shaft stub projecting into the latter, an entry opening opposite the latter and at least one discharge opening provided perpendicularly, approximately perpendicularly or tangentially to the shaft stub axis and on Lamellae or the like attached to the stub shaft, reaching up to the entry opening. Instead of lamellae, blades which are curved in the axial direction and / or transversely thereto can also be used.

Aus der DE-OS 26 09 710.9-23 ist eine derartige Vorrichtung bekannt. Das zylindrische Gehäuse dieser bekannten Vorrichtung weist Innenzähne auf, die mit den entsprechend gezähnten Lamellen kämmen.Das gemischte Fördergut tritt annähernd radial durch Löcher oder Schlitze aus und wird zur Austragsöffnung geleitet. Die Gehäuseinnenwandung wird durch teilzylindrische Ringsegmente gebildet, die in Wirkstellung miteinander verkeilt werden.Such a device is known from DE-OS 26 09 710.9-23. The cylindrical housing of this known device has internal teeth which mesh with the correspondingly serrated lamellae. The mixed conveyed material emerges approximately radially through holes or slots and is guided to the discharge opening. The inner wall of the housing is formed by partially cylindrical ring segments which are wedged together in the operative position.

Der Erfindung liegt die Aufgabe zugrunde, mit dem Zerkleinerungseffekt auch die Aussiebung des zerkleinerten Förderguts zu erhöhen und zu verbessern.The invention has for its object with the chopping effect to increase and improve the screening of the crushed material.

Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß an der Innenseite mindestens teilweise einzelne Ringe angeordnet sind, deren jeweiliger Abstand den Zerkleinerungsgrad des austretenden Förderguts bestimmt und daß die Lamellen o.dgl. einen dem Querschnitt der beabstandeten Ringe angepaßten Außenrand aufweisen. Diese Vorrichtung eignet sich vornehmlich für ein breiiges, ein Fluidum enthaltendes Fördergut; es ist für trockenes Fördergut weniger geeigent.The object is achieved in that, according to the invention, individual rings are at least partially arranged on the inside, the respective spacing of which determines the degree of comminution of the conveyed material emerging and that the slats or the like. have an outer edge adapted to the cross section of the spaced rings. This device is primarily suitable for a pulpy conveyed material containing a fluid; it is less suitable for dry goods.

Die Innenwand des Gehäuses wird somit in Einzelringe "aufgeteilt", zwischen denen jeweils das Fördergut austreten kann; letzteres wird dann gesammelt zur Austragsöffnung gefördert. Die Ringe werden beispielsweise in einem Abstand von nur zwei Millimetern, in manchen Fällen auch nur 1 mm in das Gehäuse eingesetzt, z.B. verkeilt, so daß das zerkleinerte Fördergut nicht nur an einer vorgesehenen Stelle, sondern an allen Ringzwischenräumen austreten kann. Das Fördergut kann fein- oder grobstückig sein; es kann flüssig, breiig oder trocken; es muß jedoch mindestens an der Austragsseite fließfähig sein.The inner wall of the housing is thus "divided" into individual rings, between which the material to be conveyed can emerge; the latter is then conveyed to the discharge opening. For example, the rings are inserted into the housing at a distance of only two millimeters, in some cases only 1 mm, e.g. wedged, so that the comminuted material to be conveyed can emerge not only at a designated point, but at all interstices between the rings. The material to be conveyed can be fine or coarse; it can be liquid, mushy or dry; however, it must be flowable at least on the discharge side.

Nach einer bevorzugten Ausführungsform der Erfindung weisen die Ringe einen unterschiedlichen Querschnitt auf. Hierdurch besteht die Möglichkeit, den Zerkleinerungseffekt z.B. gegenüber gezahnten, miteinander kämmenden Flächen zu vergrößern und dennoch den durch den Abstand der Ringe herbeigeführten Aussiebungszweck nicht zu beeinträchtigen.According to a preferred embodiment of the invention, the rings have a different cross section. This makes it possible to reduce the crushing effect e.g. compared to toothed, intermeshing surfaces and yet not impair the screening purpose brought about by the spacing of the rings.

Die Ringe können eine unterschiedliche Stärke aufweisen.The rings can have different thicknesses.

Nach einer abgewandelten Ausführungsform der Erfindung ist mindestens ein Ring mit in radialer Richtung nach innen gerichteten Vorsprüngen versehen. Diese nach innen ragenden Vorsprünge können im Querschnitt rechteckig und in Achsrichtung mit Aussparungen versehen sein; auch können die Aussparungen eines Ringes unterschiedliche Größen aufweisen. Die Aussparungen können annähernd rechteckig sein.According to a modified embodiment of the invention, at least one ring is provided with projections directed inwards in the radial direction. These protrude inwards the projections can be rectangular in cross-section and provided with recesses in the axial direction; the cutouts of a ring can also have different sizes. The cutouts can be approximately rectangular.

Mindestens ein Ring weist vorzugsweise eine runde,glatte Innenfläche auf.At least one ring preferably has a round, smooth inner surface.

Wenn mindestens zwei Lamellen o.dgl. vorgesehen sind, erstrecken sie sich zweckmäßigerweise in radialer Richtung geradlinig; die Lamellen o.dgl. können auch in Achsrichtung geradlinig verlaufen.If at least two slats or the like. are provided, they expediently extend in a straight line in the radial direction; the slats or the like can also be straight in the axial direction.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Außenränder der Lamellen meanderförmig ausgebildet.According to a preferred embodiment of the invention, the outer edges of the slats are meandering.

Aus Wirtschaftlichkeitsgründen finden nur zwei verschiedene Ringtypen Verwendung, obgleich dies selbstverständlich keine Bedingung für den Querschnitt der Einzelringe ist.; es ist natürlich auch möglich, daß die Außenränder der Lamellen o.dgl. mindestens teilweise zahnförmig und die Innenfläche der Ringe entsprechend ausgebildet sind.For reasons of economy, only two different ring types are used, although this is of course not a requirement for the cross section of the individual rings .; it is of course also possible that the outer edges of the slats or the like. are at least partially tooth-shaped and the inner surface of the rings are designed accordingly.

In an sich bekannter Weise bilden die Innenränder der Lamellen o.dgl. und die Stirnseite des Wellenstumpfes einen sich kegelstumpfartig zur Eintrittsöffnung hin erweiternden Ansaughohlraum, welcher sich mindestens auf die halbe Gehäuselänge, vorzugsweise auf zwei Drittel bis drei Viertel der Gehäuselänge erstreckt.In a manner known per se, the inner edges of the slats or the like form. and the end face of the stub shaft has a suction cavity which widens like a truncated cone towards the inlet opening and extends at least to half the length of the housing, preferably to two thirds to three quarters of the length of the housing.

Da die sich gegenüberstehenden Flächen der Einzelringe und der Lamellenaußenränder den Zerkleinerungseffekt bestimmen und diese Flächen wesentlich größer sind als beispielsweise bei sägezahnförmigen Lamellenaußenrändern und einem entsprechend im Inneren verzahnten Gehäuse, wird durch die erfindungsgemäße Vorrichtung der Zerkleinerungseffekt erhöht; neben dieser Wirkung wird jedoch auch die Aussiebung insofern verbessert und erhöht, als das zerkleinerte Gut nicht nur im Bereich von Löchern der Wurzel der Innenzähne des Gehäuses austreten kann, sondern gewissermaßen in der Summe der Zwischenräume zwischen den einzelnen Ringen. Wenn zum Beispiel jeweils um 90° versetzt vier radial verlaufende geradlinige Lamellen o.dgl. Verwendung finden, wird auch die Förderleistung der Vorrichtung wesentlich gesteigert und zum Beispiel gegenüber einer Zerkleinerungsvorrichtung mit einer Schrägscheibe und einer Verzahnung um ca. 30 % erhöht.Since the opposing surfaces of the individual rings and the outer edges of the lamella determine the crushing effect and these surfaces are significantly larger than, for example, sawtooth-shaped outer edges of the lamella and a correspondingly toothed housing on the inside, the crushing effect is increased by the device according to the invention; in addition to this effect, however, the screening is improved and increased insofar as the zer smaller goods can emerge not only in the area of holes of the root of the inner teeth of the housing, but to a certain extent in the sum of the spaces between the individual rings. If, for example, four radially extending straight slats or the like are offset by 90 °. Used, the conveying capacity of the device is also increased significantly and, for example, increased by approximately 30% compared to a shredding device with a swash plate and teeth.

Nach einer besonders bevorzugten Ausführungsform der Erfindung ist mindestens ein Teil der Ringe an den Lamellen o.dgl. befestigt und liegt den Austrittsschlitzen gegenüber; auf diese Weise wird erreicht, daß das zwischen den sich gegenüberliegenden Flächen "zerriebene" oder zerkleinerte Fördergut unmittelbar radial austreten kann und zur Austragsöffnung gedrückt oder "abgesogen" wird.According to a particularly preferred embodiment of the invention, at least some of the rings on the slats or the like. attached and facing the outlet slots; In this way it is achieved that the "grated" or comminuted material to be conveyed can radially exit directly between the opposing surfaces and is pressed or "sucked" to the discharge opening.

Diese Ausführungsform kann dahingehend abgewandelt werden, daß jeweils neben den Ringen an den Lamellen o.dgl. Ringe angeordent sind, die an der Innenseite des Gehäuses angeordnet sind.This embodiment can be modified such that in addition to the rings on the slats or the like. Rings are arranged, which are arranged on the inside of the housing.

Auch wenn es aus Wirtschaftlichkeitsgründen zweckmäßiger sein sollte, die einzelnen Ringe zu typisieren, können auch bei der oben genannten Ausführungsform die einzelnen z.B. an der Innenseite des Gehäuses angeordneten Ringe in einer senkrecht zur Achsrichtung verlaufenden Ebene unterschiedliche Profile aufweisen.Even if it should be more expedient for reasons of economy to type the individual rings, in the embodiment mentioned above the individual rings can also be e.g. Rings arranged on the inside of the housing have different profiles in a plane running perpendicular to the axial direction.

Alle Ringe bestehen vorzugsweise mindestens aus zwei Teilen und sind zum Einbau auf die Lamellen o.dgl. aufsetzbar.All rings preferably consist of at least two parts and are or the like for installation on the slats. attachable.

Auch können zwischen den an der Innenseite des Gehäuses arretierten Ringen Abstandshalter angeordnet sein. Der Einbau der Ringeinheiten kann so erfolgen, daß die Lamellen o.dgl. zusammen mit allen Ringen in das zylindrische Gehäuse einschiebbar sind. Danach erfolgt die Arretierung der an der Innenseite des Gehäuses anliegenden Ringe und zwar auf der Höhe des Wellenstumpfes und auf der Höhe der Eintragsöffnung. Es liegt auf der Hand, daß sämtliche Ringe, seien es diejenigen auf den Lamellen o.dgl. oder seien es diejenigen auf der Innenseite des Gehäuses mit den zugeordneten Teilen drehfest verbunden sein müssen.Spacers can also be arranged between the rings locked on the inside of the housing. The ring units can be installed so that the slats or the like. together with all the rings in the cylindrical Housing can be inserted. Then the rings on the inside of the housing are locked at the height of the stub shaft and at the height of the entry opening. It is obvious that all rings, be it those on the slats or the like. or be it that those on the inside of the housing must be non-rotatably connected to the assigned parts.

  • Fig. 2 einen Schnitt gemäß Linie II-II in Fig. 1,
  • Fig. 3 einen teilweisen Schnitt durch eine andere Ausführungsform und

For example, embodiments of the invention are shown in the drawing; they are described in more detail below; it shows:
  • 1 is a partial longitudinal section through an embodiment,
  • 2 shows a section along line II-II in FIG. 1,
  • Fig. 3 is a partial section through another embodiment and
  • 4 shows a section along line IV-IV in FIG. 3.

In einem ein Rohr 1 aufweisenden zylindrischen Gehäuse, welches eine segmentartige öffnung 2 aufweist, sind über Abstandshalter 3,4 und einePnssfpder 5 insgesamt neun einzelne Ringe drehfest und zentriert gehalten.In a cylindrical housing having a tube 1 and having a segment-like opening 2, a total of nine individual rings are held in a rotationally fixed and centered manner by means of spacers 3, 4 and a pnssf p of FIG.

Es sind zwei Typen von Ringen vorgesehen und zwar fünf Ringe 6 und vier Ringe 7, wobei die beiden Ringtypen einen unterschiedlichen lichten Durchmesser aufweisen.Two types of rings are provided, namely five rings 6 and four rings 7, the two ring types having a different clear diameter.

Zwischen dem Rohr,1 und der Außenfläche 11 der Ringe entsteht ein annähernd zylindrischer Hohlraum, welcher sich jedoch zu der der Passfeder 5 gegenüberliegenden Seite erweitert und schließlich zur Öffnung 2 im Rohr führt. Die öffnung 2 führt zu einer tangentialen Austragsöffnung 12, die einen rechteckigen Querschnitt aufweist.Between the tube 1 and the outer surface 11 of the rings, an approximately cylindrical cavity is created, which however widens to the side opposite the feather key 5 and finally leads to the opening 2 in the tube. The Opening 2 leads to a tangential discharge opening 12 which has a rectangular cross section.

Die Ringe 6 haben, wie aus Fig. 2 ersichtlich, in Kreisrichtung jeweils mit Abständen 13 vorgesehene Vorsprünge 14, welche eine runde Innenfläche 15 und eine in Axialrichtung verlaufende Aussparung 16 aufweisen. Diese Aussparung 16 hat annähernd einen rechteckigen Querschnitt und erstreckt sich auf die volle Breite der jeweiligen Ringe 6. Wie aus Fig. 2 ersichtlich ist, haben diese in Achsrichtung verlaufenden Aussparungen 16 eine unterschiedliche Tiefe und zwar jeweils innerhalb des Ringtyps 6. Die Tiefe kann bei der dargestellten Ausführungsform zwischen ein und fünf Millimeter variieren, wobei die Breite der Aussparung jeweils gleich sein kann.As can be seen from FIG. 2, the rings 6 each have projections 14 provided with intervals 13 in the circular direction, which have a round inner surface 15 and a recess 16 running in the axial direction. This recess 16 has an approximately rectangular cross section and extends over the full width of the respective rings 6. As can be seen from FIG. 2, these recesses 16 running in the axial direction have a different depth, specifically within the ring type 6. The depth can be at the illustrated embodiment vary between one and five millimeters, the width of the recess can be the same.

Die vier Ringe 7 haben eine zylindrische Innenfläche 20 und verteilt über diese ebenfalls rechteckige Aussparungen 21; auch diese Aussparungen 21 in den Ringen erstrecken sich über die gesamte Breite der Ringe und können rechteckig ausgebildet sein; auch kann die Tiefe der Aussparungen 21 beispielsweise zwischen einem und fünf Millimeter variieren.The four rings 7 have a cylindrical inner surface 20 and also distribute rectangular recesses 21; these recesses 21 in the rings also extend over the entire width of the rings and can be rectangular; the depth of the recesses 21 can also vary, for example, between one and five millimeters.

Wie aus Fig. 1 ersichtich, ist jeweils zwischen den Ringen 6 und 7 ein Zwischenraum 22 vorgesehen, der zum annähernd zylindrischen Hohlraum führt, so daß - wie weiter unten näher ausgeführt - das ausgetragene Fördergut durch die Zwischenräume zwischen den Ringen herausgedrückt wird und zur Austragsöffnung 12 wandert. Der Zerkleinerungsgrad des aus den insgesamt acht Zwischenräumen 22 austretenden Fördergutes ist somit durch diese Zwischenräume bestimmt; da die Zwischenräume verteilt über das ganze Gehäuse gleich sind, wird ein mit höchster Genauigkeit gleichförmig zerkleinertes Fördergut der Austragsöffnung zugeführt.As can be seen from Fig. 1, a space 22 is provided between the rings 6 and 7, which leads to the approximately cylindrical cavity, so that - as explained in more detail below - the discharged material is pressed out through the spaces between the rings and to the discharge opening 12 hikes. The degree of comminution of the conveyed material emerging from the total of eight spaces 22 is thus determined by these spaces; Since the gaps are the same over the entire housing, a material to be conveyed that is crushed uniformly with the greatest accuracy is fed to the discharge opening.

Am Wellenstumpf 9 sind vier Lamellen 30 angebracht, die jeweils um 90° versetzt radial verlaufen und sich auch geradlinig in Achsrichtung erstrecken.On the stub shaft 9 four slats 30 are attached, the run radially offset by 90 ° and also extend in a straight line in the axial direction.

Die Lamellen 30 weisen jeweils einen meanderförmig ausgebildeten Außenrand 31 auf, welcher dem Profil der beabstandeten einzelnen Ringe entspricht.The slats 30 each have a meandering outer edge 31, which corresponds to the profile of the spaced individual rings.

Der Innenrand 32 der Einzellamellen öffnet sich kegelstumpfförmig zur Austragsöffnung 33, wodurch das in den Ansaughohlraum 34 eintretende Fördergut im wesentlichen in radialer Richtung nach außen geschleudert oder gedrückt wird und nach der gewünschten Zerkleinerung durch die Austragsöffnung 12 austreten kann.The inner edge 32 of the individual lamellas opens in the shape of a truncated cone to the discharge opening 33, as a result of which the material to be conveyed entering the suction cavity 34 is thrown or pressed essentially in the radial direction and can exit through the discharge opening 12 after the desired size reduction.

Es liegt auf der Hand, daß neben dem sehr hohen Zerkleinerungsgrad auch ein sehr günstiger Mischeffekt erreicht wird, so daß sich.die Vorrichtung auch zum Homogenisieren oder Emulgieren von bestimmten Fördergütern mit einem hohen Gehalt an Feststoffbestandteilen eignet.It is obvious that in addition to the very high degree of comminution, a very favorable mixing effect is also achieved, so that the device is also suitable for homogenizing or emulsifying certain conveyed goods with a high content of solid components.

Nach dem Einschieben der einzelnen Ringe 6 und 7 werden diese mit dem Gehäuse durch einen Ring 8 verkeilt. Die Lamellen können durch in Achsrichtung in den Ringen verlaufenden Aussparungen 13' eingeschoben und dann mit dem Wellenstumpf verbunden werden.After inserting the individual rings 6 and 7, these are wedged to the housing by a ring 8. The slats can be inserted through recesses 13 'running in the axial direction in the rings and then connected to the stub shaft.

Die einzelnen Ringe werden beim Einsetzen längs den Abstandshaltern 3 bzw. 4 verschoben und dann durch die Paßfeder 5 arretiert.The individual rings are moved along the spacers 3 and 4 when inserted and then locked by the key 5.

Es liegt auf der Hand, daß die Profilierung der einzelnen Ringe unterschiedlich sein kann und daß es entschei- dend nur darauf ankommt, daß zwischen mehreren einzelnen Ringen Zwischenräume von beispielsweise zwei bis-sogar nur ein Millimeter vorgesehen werden, um den Austritt des Fördergutes in radialer Richtung in den annähernd zylindrischen Hohlraum überall- verteilt auf den Querschnitt - zu ermöglichen.It is obvious that the profiling of the individual rings may be different and that it is decisive - DEND only it arrives, that even bis-provided between a plurality of individual rings interspaces of, for example two, only one millimeter radial to the outlet of the transported material in Direction in the approximately cylindrical cavity everywhere - distributed over the cross section - to allow.

Wie aus Fig. 1 ersichtlich ist, weist der Ring 8 eine Innenverzahnung 36 auf, auf welche ein Ring 37 aufgeschoben werden kann, welcher über einen Abstandsring 38 die einzelnen Ringe 6 und 7 in axialer Richtung festhält. Der Zwischenraum 22 zwischen den einzelnen Ringen kann beispielsweise durch an den Seitenflächen 39 der jeweiligen Ringe vorgesehene Vorsprünge hergestellt werden.As can be seen from FIG. 1, the ring 8 has an internal toothing 36, onto which a ring 37 can be pushed, which holds the individual rings 6 and 7 in the axial direction via a spacer ring 38. The space 22 between the individual rings can be produced, for example, by projections provided on the side surfaces 39 of the respective rings.

Während bei der dargestellten Ausführungsform die Außenränder der Lamellen 30 meanderförmig ausgebildet sind, kann selbstverständlich auch ein anderes Profil, z.B. eine Annäherung an ein zahnförmiges Profil gewählt werden; auch ist es möglich, die Zahl der Ringtypen zu erhöhen, die Abstände zwischen den einzelnen Ringen zu vergrößern und auch statt der rechteckigen,-Aussparungen 16 bzw. 2-1 anders geformte Aussparungen in Achsrichtung vorzusehen.While in the illustrated embodiment the outer edges of the slats 30 are meandering, a different profile, e.g. an approximation to a tooth-shaped profile can be chosen; it is also possible to increase the number of ring types, to increase the spacing between the individual rings and also to provide differently shaped recesses in the axial direction instead of the rectangular cutouts 16 or 2-1.

Nach einer abgewandelten, nicht dargestellten Ausführungsform weisen die Ringe 7 eine glatte Innenfläche auf, so daß also in diesen Ringen keine Aussparungen 21 vorgesehen sind.According to a modified, not shown embodiment, the rings 7 have a smooth inner surface, so that no recesses 21 are provided in these rings.

Das Profil der Ringe 7 bei der dargestellten Ausführungsform ist annähernd T-förmig; statt diesem Profil kann selbstverständlich auch ein Rechteckprofil vorgesehen werden, so daß derZwischenraum 22 für die Zerkleinerung sich über die gesamte axiale Tiefe des Ringes 7 erstreckt.The profile of the rings 7 in the illustrated embodiment is approximately T-shaped; instead of this profile, a rectangular profile can of course also be provided so that the intermediate space 22 for comminution extends over the entire axial depth of the ring 7.

Bei der nachfolgend im Zusammenhang mit den Fig. 3 und 4 beschriebenen Ausführungsform handelt es sich um eine solche, die besonders wesentlich ist und mit welcher ein Zerkleinerungsgrad bis zu 0,6 ggfs. weniger als 0,4 mm z.B. 0,2 mm erreicht werden kann. Während die im Zusammenhang mit Fig. 1 und 2 beschriebene Vorrichtung vornehmlich für breiige oder sehr dickflüssige Materialien geeignet ist und im wesentlichen trockenes Fördergut nur schwierig zerkleinert werden kann, eignet sich die nachfolgend beschriebene Ausführungsform für wesentlich mehr zu zerkleinerndes Fördergut, unter Umständen auch im Trockenzustand; entscheidend ist nur, daß an der Austragsöffnung eine flüssigfähige Substanz entsteht oder vorhanden ist.The embodiment described below in connection with FIGS. 3 and 4 is one which is particularly essential and with which a degree of comminution of up to 0.6, possibly less than 0.4 mm, for example 0.2 mm, is achieved can. While the device described in connection with FIGS. 1 and 2 is primarily suitable for pulpy or very viscous materials and essentially dry material to be conveyed can only be crushed with difficulty, the embodiment described below is suitable for much more material to be shredded, possibly also in the dry state; the only important thing is that a liquid substance is formed or is present at the discharge opening.

Während der grundsätzliche Aufbau der in Fig. 3 und 4 bezeichneten Ausführungsform derjenigen nach der vorhergehenden Ausführungsform gleicht, sind am Wellenstumpf 40 vier Lamellen 41 angebracht; diese Lamellen erstrecken sich in Achsrichtung und in radialer Richtung jeweils geradlinig; sie können jedoch auch in einer oder in beiden Richtungen gebogen sein. Bei dieser Ausführungsform sind zwei Typen von Ringen 43 und 44 vorgesehen, wobei die Ringe 42 bei der dargestellten Ausführungsform mit rechteckigem Querschnitt an den Lamellen 41 befestigt, z.B. aufgekeilt sind und die Ringe 44 mit der Innenwand 45 des Gehäuses 46 in drehfester Verbindung stehen.While the basic structure of the embodiment shown in FIGS. 3 and 4 is the same as that according to the previous embodiment, four slats 41 are attached to the stub shaft 40; these slats each extend in a straight line in the axial direction and in the radial direction; however, they can also be curved in one or both directions. In this embodiment, two types of rings 43 and 44 are provided, the rings 42 in the illustrated embodiment being attached to the slats 41 with a rectangular cross-section, e.g. are wedged and the rings 44 are non-rotatably connected to the inner wall 45 of the housing 46.

Die Ringe 44 bestehen aus einem breiten Sockel 47 und einem rechteckigen Vorsprung 48. Die rechteckigen Vorsprünge 48 ähneln den Vorsprüngen 14 bei der Ausführungsform nach Fig. 1 und 2 und haben unterschiedlich große Aussparungen, die in axialer Richtung verlaufen.The rings 44 consist of a wide base 47 and a rectangular projection 48. The rectangular projections 48 are similar to the projections 14 in the embodiment according to FIGS. 1 and 2 and have recesses of different sizes which run in the axial direction.

Das in die trichterförmige Eintrittsöffnung eintretende grobkörnige oder kleinststückige Fördergut wird - ggfs. nach einer vorherigen Vorzerkleinerung mit einer Förderschnecke - radial nach außen geleitet, so daß es in den Randbereich der Lamellen 42 kommt. Das Fördergut wird dann in den Schlitzen 50,51 und 52 zwischen den Vorsprüngen 48 und der Lamellen weiter zerkleinert und gelangt dann durch die Schlitze 53 und 54 in den ringschlitzartigen Hohlraum 55, von dem das nunmehr endgültig zerkleinerte Fördergut über den ringförmigen Schlitz 60 in die Austragsöffnung 61 gefördert wird.The coarse-grained or very small-sized conveyed material entering the funnel-shaped inlet opening is guided radially outward, if necessary after a previous comminution with a screw conveyor, so that it comes into the edge region of the lamellae. The material to be conveyed is then further comminuted in the slots 50, 51 and 52 between the projections 48 and the lamellae and then passes through the slots 53 and 54 into the annular slot-like cavity 55, from which the finally comminuted material via the annular slot 60 into the Discharge opening 61 is promoted.

Die Korngröße des ausgetragenen Fördergutes wird durch die Abstände 53 und 54 zwischen den radial verlaufenden Wandungen der Ringe 43 und 44 bestimmt.The grain size of the material to be conveyed is determined by the distances 53 and 54 between the radial ones Walls of the rings 43 and 44 determined.

Die Montage der im Zusammenhang mit Fig. 3 und 4 beschriebenen Ausführungsform erfolgt dergestalt, daß auf die mit dem Wellenstumpf 40 verbundenen Lamellen die einzelnen Ringeinheiten 43,44 abwechselnd aufgesetzt werden und zwar dadurch, daß alle Ringe als Halbringe ausgebildet sind und somit radial auf die Lamellen aufgesetzt oder aufgeschoben werden können. Um zu gewährleisten, daß die Ringe 44 auch den genau vorgesehenen Abstand - in der Größenordnung von einigen Bruchteilen eines Millimeters haben - sind zwischen den Ringen 44 verteilt über den Umfang der beiden Halbringe mindestens drei oder mehr streifenförmige Abstandshalter 61 vorgesehen, die die Halbtiefe der Ringschlitze 55 haben und somit gewährleisten, daß die auf die Lamellen aufgekeilten Ringe 43 ihre genau bestimmte Lage zwischen den Ringen 44 einnehmen, die mit der Gehäusewand verkeilt werden. Durch die besonders große Reibfläche 53,54 zwischen den beiden Ringtypen kann relativ schnell und in relativ großem Umfang das zu zerkleinernde Fördergut "zermalen" und radial nach außen gefördert werden, so daß es die Vorrichtung über die Austragsöffnung 61 verlassen kann; an letzterer kann ggfs. zur Erhöhung der Förderwirkung eine Pumpe eingeschaltet sein.The embodiment described in connection with FIGS. 3 and 4 is assembled in such a way that the individual ring units 43, 44 are placed alternately on the lamellae connected to the stub shaft 40, namely in that all rings are designed as half rings and thus radially on the Slats can be placed or pushed on. In order to ensure that the rings 44 also have the precisely provided spacing - of the order of a few fractions of a millimeter - at least three or more strip-shaped spacers 61 are provided between the rings 44 over the circumference of the two half rings, which are half the depth of the ring slots 55 and thus ensure that the rings 43 wedged onto the slats assume their precisely defined position between the rings 44, which are wedged to the housing wall. Due to the particularly large friction surface 53, 54 between the two ring types, the material to be shredded can be "crushed" relatively quickly and to a relatively large extent and conveyed radially outward, so that it can leave the device via the discharge opening 61; a pump may be switched on at the latter to increase the conveying effect.
