Description

Die Erfindung betrifft eine Zerkleinerungsvorrichtung nach dem Oberbegriff des Anspruchs 1, welche zum Zerkleinern von Produkten jedwelcher Art, insbesondere im Rahmen von Aufbereitungsmassnahmen, z.B. bei der Entsorgung bzw. Wiederverwertung von Abfallstoffen eingesetzt wird.The invention relates to a shredding device according to the preamble of Claim 1, which for crushing products of any kind, in particular within the scope of processing measures, e.g. during disposal or Recycling of waste materials is used.

Bei solchen Zerkleinerungsmaschinen kann es sich z.B. um Rotorscheren handeln, deren Zerkleinerungseffekt dadurch erreicht wird, dass an ihrem Umfang mit Zähnen versehene Rotorscheiben (Schneideringe) gegeneinander drehen. Der dadurch erreichte Schneid-, Reiss- und Brucheffekt ist unter anderem eine Funktion der Distanz zwischen der Nase der Rotorscheiben und der dieser jeweils gegenüberliegenden Fläche, sowie der Distanz zwischen den Seitenflächen der Rotorscheiben.Such shredding machines can e.g. are rotor shears, their crushing effect is achieved by the fact that their teeth are used on their circumference Turn the provided rotor discs (cutting rings) against each other. The result The cutting, tearing and breaking effect achieved is, among other things, a function of Distance between the nose of the rotor disks and that of each opposite surface, as well as the distance between the side surfaces of the Rotor discs.

In Abhängigkeit von dem zu zerkleinernden Material ist der Verschleiss der Rotorscheiben bzw. der Rotorscheibensegmente mehr oder weniger gross, wobei der Zerkleinerungseffekt durch die verschleissbedingte, zunehmende Vergrösserung der frontalen und seitlichen Zwischenräume abnimmt.Depending on the material to be shredded, the wear is Rotor disks or the rotor disk segments more or less large, whereby the shredding effect due to the increasing magnification caused by wear of the frontal and lateral spaces decreases.

Um die gewünschte Funktionsfähigkeit wieder herzustellen, müssen die verschlissenen Teile ausgetauscht und / oder aufgearbeitet werden (Problemstellung 1).To restore the desired functionality, the worn out Parts are exchanged and / or refurbished (problem 1).

Im Falle von Zerkleinerungsmaschinen, die unter speziell harten Bedingungen arbeiten, beschränkt der Verschleiss sich jedoch nicht nur auf die eigentlichen Rotorscheibensegmente bzw. Zerkleinerungswerkzeuge, sondern betrifft auch die zwischen den Rotorscheibensegmenten liegende Wellenoberfläche (Problemstellung 2). Diesen Verschleiss hat man bisher durch den Einsatz gehärteter Wellen (sehr teuer!) oder durch die Abdeckung mit Distanzhaltern zu verhindern, oder durch das Aufschweissen von Material auf verschlissene Stellen zu beseitigen gesucht. Beide letztgenannten Massnahmen sind aber ebenfalls sehr umständlich, insbesondere der Austausch verschlissener Distanzhalter, bzw. gefährlich, wie z.B. das Schweissen in der Umgebung von Chemieabfällen.In the case of crushing machines, which are under particularly tough conditions work, the wear and tear is not limited to the actual ones Rotor disc segments or crushing tools, but also affects the shaft surface lying between the rotor disk segments (problem 2). This wear and tear has so far been achieved through the use of hardened shafts (very expensive!) or by covering with spacers, or by the Welding of material on worn areas sought to eliminate. Both the latter measures are also very cumbersome, in particular the Replacement of worn spacers, or dangerous, such as the welding in the area of chemical waste.

Ausserdem werden die Rotoren bzw. Distanzhalter durch den Verschleiss statisch geschwächt (Bruchgefahr) und die Abstreifer funktionieren schlechter (Problemstellung 3). In addition, the rotors or spacers become static due to the wear weakened (risk of breakage) and the wipers work worse (Problem 3).

Aufgrund der hohen Anforderungen an die Stabilität und Sicherheit der Zerkleinerungsvorrichtungen und der sich daraus ergebenden hohen Gewichte ist ein Austausch der Rotoren und/oder der Distanzhalter aufgrund der dadurch verursachten Stillstandszeiten, der notwendigen Hebezeuge sowie eventuell baulicher Massnahmen, sowie schliesslich aufgrund des qualitätsbedingten, hohen Preises der Rotoren mit bedeutenden Kosten verbunden.Due to the high demands on the stability and security of the Crushers and the resulting high weights is one Replacement of the rotors and / or the spacers due to this caused downtimes, the necessary lifting equipment and possibly structural measures, and finally due to the high quality The price of the rotors is associated with significant costs.

Das in der EP-A1-6.261 (deren Inhalt hiemit als im Rahmen dieser Beschreibung geoffenbart gilt) beschriebene System der ohne Wellendemontage austauschbaren Zerkleinerungswerkzeuge bzw. Rotorscheibensegmente mit U-förmigem Querschnitt, ebenso wie das in der US-A-3,991,944 beschriebene System erlauben, Zeit und Kosten für den Austausch der verschlissenen Rotorscheibensegmente (Problemstellung 1) ausreichend zu reduzieren, tragen jedoch nichts zur Lösung der Problemstellungen 2 und 3 bei.This in EP-A1-6.261 (the content of which is therefore within the scope of this description disclosed system applies) described system of interchangeable without shaft disassembly Crushing tools or rotor disk segments with a U-shaped Cross section, just as the system described in US-A-3,991,944 allow Time and costs for replacing the worn rotor disc segments (Problem 1) to reduce sufficiently, but do nothing to solve the problem Problems 2 and 3 at.

Die Erfindung hat sich daher die Aufgabe gestellt, die Problemstellungen 2 und 3 preisgünstig zu lösen, ohne aber die bekannte Lösung für die Problemstellung 1 zu vernachlässigen. Diese Aufgabe wird durch die Kombination der im Kennzeichen des Anspruchs 1 beschriebenen Merkmale mit denjenigen aus seinem Oberbegriff gelöst. Vorteilhafte Weiterbildungen sind in den Kennzeichen der abhängigen Ansprüche beschrieben.The invention is therefore based on the problem 2 and 3 inexpensive to solve, but without the known solution to problem 1 to neglect. This task is achieved through the combination of the characteristics of the Features described claim 1 solved with those from its preamble. Advantageous further developments are in the characterizing part of the dependent claims described.

Aufgrund der langen Lebensdauer von Zerkleinerungsvorrichtungen ist es wünschenswert, dass auch bestehende Modelle mit einem minimalen Aufwand mit den neuartigen Rotorscheibensegmenten in U-Form mit Wellenschutz-Fortsätzen bestückt werden können. Solche Rotoren werden vorzugsweise für Zerkleinerungsanlagen mit Hydraulikantrieb verwendet, welche durch geeignete Massnahmen - z.B. durch Umkehrdrehungen, Wegfahren der Gegenmesser, oder automatischen Stillstand der Anlage - die Gefahr des Rotorenbruchs oder des Verschleisses bei extrem schwierigen Ausgangsprodukten zusätzlich mindern.Because of the long life of shredders, it is desirable that even existing models with minimal effort the new U-shaped rotor disc segments with shaft protection extensions can be equipped. Such rotors are preferably used for Shredding systems with hydraulic drive used by suitable Measures - e.g. by reversing turns, moving away the counter knife, or automatic standstill of the system - the risk of rotor breakage or Reduce wear on extremely difficult starting products.

Sinngemäss können solche Rotoren jedoch in analoger Weise auch für andere Zerkleinerungsmaschinen (Schnell- oder Langsamläufer), unabhängig von deren Antriebsart (z.B. hydraulisch, elektrisch, oder mittels Verbrennungsmotoren), der Anzahl der festen oder drehenden Rotoren (z.B. 1,2,3 oder auch mehr) eingesetzt werden. Analogously, however, such rotors can also be used in an analogous manner for others Shredding machines (high or low speed), regardless of their Drive type (e.g. hydraulic, electric, or by means of internal combustion engines), the Number of fixed or rotating rotors (e.g. 1,2,3 or more) used become.

In der beiliegenden Zeichnung eines ringförmigen Bundes und des darüber gestülpten Rotorscheibensegmentes im Schnitt wird die Erfindung beispeilhaft näher erläutert.
Es zeigen

  • Fig.1 den Stand der Technik nach der EP-B1-6,261, und die
  • Fig.2 bis 4 erfindungsgemäss verbesserte Ausführungsformen des Rotorscheibensegmentes.
    • In the accompanying drawing of an annular collar and the rotor disc segment placed over it on average, the invention is explained in more detail.
    Show it
  • 1 shows the prior art according to EP-B1-6.261, and
  • 2 to 4 improved embodiments of the rotor disc segment according to the invention.

    • Auf einer Welle 1 sind ringförmige, bei einer praktischen Ausführungsform axial etwa 30-40 mm breite Bunde 2 angeordnet, die in an sich bekannter Weise entweder einstückig mit dieser ausgebildet sind (Fig.1 bis 4) oder (nicht dargestellt) auf eine Sechskant-Welle geschoben bzw. über eine Zahnverbindung mit ihr verbunden sind.On a shaft 1 are annular, in a practical embodiment, axially about 30-40 mm wide bundles 2 arranged in a manner known per se are either integrally formed with this (Fig. 1 to 4) or (not shown) pushed onto a hexagon shaft or via a tooth connection with it are connected.

    Die über die Bunde 6 gestülpten, bei einer praktischen Ausführungsform axial etwa 80-85 mm breiten, U-förmigen Rotorscheibensegmente 2 bzw. 2a (Fig.1 und 2) sind mit diesen in an sich bekannter Weise, z.B. über eine (nicht dargestellte) vorgespannte "Zapfen-Schraube"-Einheit verbunden und greifen in ringförmige Nuten 3 bzw. 3a in der Welle 1 bzw. 1a ein. Dabei sind die ringförmigen Nuten 3a (Fig.2) gegenüber den Nuten 3 (Fig.1, Stand der Technik) axial verbreitert und nehmen zwei am Schenkelende des U-förmigen Rotorscheibensegmentes 2a angebrachte Fortsätze 4 auf. Diese schützen den grösseren Teil der Wellenoberfläche vor dem Verschleiss.The slipped over the bundle 6, axially in a practical embodiment 80-85 mm wide, U-shaped rotor disc segments 2 and 2a (Fig. 1 and 2) are with these in a manner known per se, e.g. via a (not shown) preloaded "pin-screw" unit connected and engage in annular grooves 3 or 3a in shaft 1 or 1a. The annular grooves 3a (Fig.2) axially widened relative to the grooves 3 (FIG. 1, prior art) and take two attached to the leg end of the U-shaped rotor disk segment 2a Extensions 4 on. These protect the larger part of the shaft surface from the Wear.

    In der Ausführungsform nach Fig.3 tragen die Rotorscheibensegmente 2b nur einen Fortsatz 4b, der im wesentlichen den gesamten Abstand zwischen zwei benachbarten Rotorscheibensegmenten 2b überbrückt. Dadurch erübrigt sich die Herstellung einer Nut in der Wellenoberfläche.In the embodiment according to FIG. 3, the rotor disk segments 2b carry only one Extension 4b, which is essentially the entire distance between two bridging adjacent rotor disk segments 2b. This eliminates the need Creation of a groove in the shaft surface.

    Natürlich kann, wie dies in Fig.4 dargestellt ist, auf eine solche Nut auch dann verzichtet werden - bei gleicher Ausbildung der Welle 1b wie in Fig.3 - wenn die Rotorscheibensegmente 2c an beiden Enden der U-Schenkel Fortsätze 4c tragen, von denen jeder in seiner axialen Erstreckung so ausgebildet ist, dass ergemeinsam mit dem ihm gegenüberliegenden Fortsatz 4c des jeweils benachbarten Rotorscheibensegmentes 2c - im wesentlichen den gesamten Abstand zwischen zwei benachbarten Rotorscheibensegmenten 2c überbrückt. Of course, as shown in FIG. 4, such a groove can also be used be dispensed with - with the same design of the shaft 1b as in Fig. 3 - if the Wear rotor disc segments 2c at both ends of the U-legs extensions 4c, each of which is designed in its axial extent to be common with the opposite extension 4c of the adjacent one Rotor disc segment 2c - essentially the entire distance between bridges two adjacent rotor disk segments 2c.

    Der in Fig.3 gezeigte Lichtspalt 5b zwischen dem Fortsatz 4b und dem benachbarten Rotorscheibensegment 2b, bzw. der in Fig.4 gezeigte Lichtspalt 5c zwischen zwei benachbarten Fortsätzen 4c kann entweder so klein ausgebildet sein, dass er nur allfällige Wärmedehnungen aufnimmt, oder bewusst einen Teil der Wellenoberfläche unabgedeckt lassen, was einerseits eine fertigungstechnische Vereinfachung bedeutet, andererseits einer Verkeilung von Materialteilchen entgegenwirkt und damit die Demontage erleichtert.The light gap 5b shown in FIG. 3 between the extension 4b and the neighboring one Rotor disc segment 2b, or the light gap 5c shown in Figure 4 between two adjacent extensions 4c can either be made so small that it only absorbs any thermal expansion, or deliberately part of the shaft surface leave uncovered, which on the one hand simplifies production means on the other hand counteracts wedging of material particles and to make disassembly easier.

    In der Ausführungsform nach Fig.5 ist die konkave Innenseite der Rotorscheibensegmente 2d mit einer Evolventenverzahnung 7 versehen, die mit einer analogen Verzahnung 8 an der Oberfläche der Welle 1c zusammenwirkt. Eine solche Ausgestaltung ist - gegenüber einer grundsätzlich möglichen Ausbildung der Welle als Keilwelle oder Sechskantwelle - bevorzugt, weil die Bruchgefahr verringert, die Montage und Demontage erleichtert, und die Kraftübertragung verbessert wird.In the embodiment of Figure 5, the concave inside is Provide rotor disk segments 2d with an involute toothing 7, which with an analog toothing 8 cooperates on the surface of the shaft 1c. A such a configuration is - compared to a fundamentally possible training of Shaft as spline shaft or hexagonal shaft - preferred because the risk of breakage is reduced, assembly and disassembly are made easier, and power transmission is improved.
