The screen element has excentric passages (19), which are arranged around the centric passage for driver profiles such that the driver profiles running parallel to a screen shaft are plugged by the excentric passages. The screen element is made of rubber, polyurethane or another rubber-like material. An independent claim is also included for a screen shaft with a distance piece.

Description

Die Erfindung betrifft ein Siebelement für Stern- oder Scheibensiebe, mit einem mittigen Durchlass für eine Siebwelle. Daneben betrifft die Erfindung eine Siebwelle und ein Stern-oder Scheibensieb.The invention relates to a sieve element for star or disc sieves, with a central passage for a sieve shaft. In addition, the invention relates to a screen shaft and a star or Scheibensieb.

Siebaggregate nach Art von Sternsieben werden unter anderem für die Siebung von Schotter und Steinen, ggf. auch in Verbindung mit bindigem Boden, verwendet. Bevorzugte Anwendungen sind die Siebung von Bahnschotter, Steinen im Größenbereich 5 bis 80 mm und/oder Steinbruchmaterial. Die vorliegende Erfindung befasst sich in erster Linie mit Siebelementen und Siebwellen für Sternsiebe. Die Erfindung kann aber auch im Zusammenhang mit Scheibensieben verwendet werden.Siege units in the manner of star screens are used, inter alia, for the screening of ballast and stones, possibly also in connection with cohesive soil. Preferred applications are the screening of ballast, stones in the size range 5 to 80 mm and / or quarry material. The present invention is primarily concerned with sieve elements and sieve shafts for star screens. However, the invention can also be used in connection with disc sieves.

Bekannte Sternsiebe weisen mehrere in einer Ebene angeordnete und zueinander parallele Siebwellen mit jeweils mehreren Siebelementen, nämlich Siebsternen auf. Die Siebsterne unmittelbar zueinander benachbarter Siebwellen sind auf Versatz angeordnet und kämmen miteinander. Der Abstand der Siebwellen voneinander, der Abstand benachbarter Siebsterne auf jeweils derselben Siebwelle und die Abmessungen der einzelnen Siebsterne beeinflussen den Siebeffekt bzw. das Siebergebnis. Daneben sind der Werkstoff der Siebsterne und die Drehzahl derselben von Bedeutung. Ziel ist ein möglichst genauer Siebvorgang. Das heißt, definierte kleine Größen sollen durch das Sieb hindurchfallen. Demgegenüber größere Teile sollen von drehenden Siebsternen über das Sieb hinweggefördert werden.Known star screens have a plurality of screen shafts arranged in a plane and parallel to one another, each with a plurality of sieve elements, namely screen stars. The screen stars directly adjacent sieve shafts are arranged on offset and mesh with each other. The distance of the screen shafts from each other, the distance between adjacent screen stars on the same screen shaft in each case and the dimensions of the individual screen stars influence the screening effect or the screening result. In addition, the material of the screen stars and the speed of the same are important. The goal is a very accurate screening process. That is, defined small sizes are meant by the Sieve fall through. In contrast, larger parts are to be carried away by rotating screen stars on the screen.

Die Siebelemente sind auf die Siebwellen aufgeschoben und durch Reibschluss oder in Drehrichtung wirksamen Formschluss auf den Siebwellen gehalten, beispielsweise bei Verwendung von Vierkant-Siebwellen. Das Drehmoment der angetriebenen Siebwellen muss dabei auf die Siebelemente übertragen werden. Insbesondere Siebsterne sind aus nachgiebigem Werkstoff, wie Gummi oder gummiähnlichen Werkstoffen (z. B. PU) hergestellt. Für die Übertragung hoher Drehmomente weisen deshalb die Siebelemente, insbesondere Siebsterne, eine über die im Übrigen scheibenförmige Umrissgestalt axial überstehende Nabe auf. Durch die Nabe ist die an der Siebwelle anliegende Fläche des Siebelements vergrößert.The sieve elements are pushed onto the screen shafts and held on the screen shafts by frictional engagement or in the direction of rotation, for example when using square screen shafts. The torque of the driven screen shafts must be transferred to the screen elements. In particular, screen stars are made of resilient material, such as rubber or rubber-like materials (eg PU). For the transmission of high torques, therefore, the sieve elements, in particular sieve stars, have an over the otherwise discoidal outline shape axially projecting hub. Through the hub, the voltage applied to the screen shaft surface of the sieve is increased.

Nachteil der Siebelemente mit Nabe ist die relativ aufwendige Herstellung. Die Siebelemente werden üblicherweise im Gussverfahren hergestellt.Disadvantage of the screen elements with hub is the relatively expensive production. The sieve elements are usually produced by casting.

Aufgabe der vorliegenden Erfindung ist die Schaffung eines Siebelements, welches besonders kostengünstig herstellbar ist. Dies soll gleichermaßen für die Siebwelle und das Sieb gelten. Außerdem soll in Fortbildung der Erfindung trotz der fehlenden Nabe eine hohe Drehmomentübertragung möglich sein.Object of the present invention is to provide a Siebelements, which is particularly inexpensive to produce. This should apply equally to the screen shaft and the sieve. In addition, should be possible in training of the invention, despite the lack of hub high torque transmission.

Das erfindungsgemäße Siebelement ist gekennzeichnet durch eine Gestaltung mit im Wesentlichen gleicher Dicke, d. h. ohne Bereiche abweichender Dicke und ohne eine axial überstehende Nabe. Dadurch können einzelne Siebelemente aus einer großen Platte ausgeschnitten werden, etwa durch Wasserstrahlschneiden. Dies gilt insbesondere für die Elemente aus Gummi oder PU oder anderem gummiartigen Werkstoff und vorzugsweise für Siebsterne. Ebenfalls möglich ist aber die erfindungsgemäße Gestaltung von Siebelementen nach Art von Siebscheiben.The screening element according to the invention is characterized by a design with substantially the same thickness, d. H. without areas of differing thickness and without an axially projecting hub. As a result, individual sieve elements can be cut out of a large plate, for example by water jet cutting. This applies in particular to the elements made of rubber or PU or other rubber-like material and preferably for screen stars. But also possible is the inventive design of sieve elements on the type of screen discs.

Nach einem weiteren Gedanken der Erfindung sind um den mittigen Durchlass herum Durchlässe für Mitnehmerprofile angeordnet, derart, dass etwa parallel zur Siebwelle verlaufende Mitnehmerprofile durch die Durchlässe steckbar sind. Durch diese Gestaltung ist es möglich, die auf der Siebwelle angeordneten Siebelemente zusätzlich durch stangenartige Mitnehmerprofile zu verbinden und so die Drehmomentübertragung insgesamt zu verbessern. Vorzugsweise sind die außermittigen Durchlässe zur Aufnahme von Rundprofilen, insbesondere Rundstangen ausgebildet. Diese sind kostengünstig und können auf einfache Weise mit Gewinden für Befestigungsmuttern versehen werden. Die Mitnehmerprofile können auch massiv ausgebildet sein.According to a further aspect of the invention, passages for driver profiles are arranged around the central passage in such a way that driver profiles extending approximately parallel to the screening shaft can be inserted through the passages. With this design, it is possible to additionally connect the screen elements arranged on the screen shaft by rod-like carrier profiles and thus to improve the overall torque transmission. Preferably, the off-center passages for receiving round profiles, in particular round rods are formed. These are inexpensive and can be easily provided with threads for fastening nuts. The Mitnehmerprofile can also be solid.

Nach einem weiteren Gedanken der Erfindung ist der mittige Durchlass zur Aufnahme einer Vielkantwelle (Polygon-Querschnitt), insbesondere einer Vierkantwelle ausgebildet. Möglich ist aber auch die Verwendung einer Siebwelle mit kreisrundem Außenquerschnitt.According to a further idea of the invention, the central passage for receiving a polygonal shaft (polygonal cross-section), in particular a square shaft is formed. However, it is also possible to use a screen shaft with a circular outer cross section.

Eine erfindungsgemäße Siebwelle ist mit Siebelementen der zuvor genannten Art besetzt. Vorzugsweise sind zwischen benachbarten Siebelementen Distanzstücke vorgesehen. Die Distanzstücke sind insbesondere scheibenförmige ausgebildet, können die sonst üblichen, axial überstehenden Nabenbereiche ersetzen und sind ebenfalls auf einfache Weise kostengünstig herstellbar. Vorzugsweise bestehen die Distanzstücke aus härterem Werkstoff als die Siebelemente.A screening shaft according to the invention is filled with sieve elements of the aforementioned type. Preferably spacers are provided between adjacent sieve elements. The spacers are in particular disc-shaped, can replace the usual, axially projecting hub areas and are also inexpensive to produce in a simple manner. Preferably, the spacers are made of a harder material than the sieve elements.

Nach einem weiteren Gedanken der Erfindung weisen die Distanzstücke einen mittigen Durchlass für die Siebwelle auf und sind insbesondere nach Art von Hülsen ausgebildet. Der mittige Durchlass in den Distanzstücken ist vorzugsweise so geformt wie in den Siebelementen.According to a further aspect of the invention, the spacers have a central passage for the screen shaft and are designed in particular in the manner of sleeves. The central passage in the spacers is preferably shaped as in the sieve elements.

Nach einem weiteren Gedanken der Erfindung weisen die Distanzstücke außermittige Durchlässe für die Mitnehmerprofile auf. Die Distanzstücke sind dann fast gleich wie die Siebelemente selbst ausgebildet, nur mit einem deutlich geringeren Außendurchmesser bzw. ohne Siebsternarme oder -zacken und aus härterem Werkstoff. Die außermittigen Durchlässe der Distanzstücke fluchten mit den außermittigen Durchlässen in den Siebelementen. Über die Mitnehmerprofile besteht in Drehrichtung Formschluss zwischen den Siebelementen und Distanzstücken.According to a further aspect of the invention, the spacers have off-center passages for the driver profiles. The spacers are then almost the same as the sieves themselves, only with a much smaller outer diameter or without Siebsternarme or -zacken and harder material. The off-center passages of the spacers are aligned with the off-center passages in the sieve elements. About the driver profiles is in the direction of rotation positive connection between the sieve elements and spacers.

Nach einem weiteren Gedanken der Erfindung sind Mittel zum axialen Zusammenpressen der Siebelemente auf der Siebwelle, insbesondere mit Distanzstücken zwischen den Siebelementen, vorgesehen. Bei den genannten Mitteln kann es sich beispielsweise um Muttern oder andere verstellbare Halteorgane an den Enden der Siebwelle handeln.According to a further aspect of the invention, means are provided for axially compressing the sieve elements on the sieve shaft, in particular with spacers between the sieve elements. The mentioned means may be, for example, nuts or other adjustable holding members at the ends of the screen shaft.

Nach einem weiteren Gedanken der Erfindung sind Mittel zum axialen Zusammenpressen der Siebelemente entlang der Mitnehmerprofile, insbesondere mit Distanzstücken zwischen den Siebelementen, vorgesehen. Bei den genannten Mitteln handelt es sich insbesondere um Halteorgane an den Enden der vorzugsweise stangenförmigen Mitnehmerprofile, etwa Klemmschrauben oder dergleichen.According to a further aspect of the invention, means for axially compressing the sieve elements along the entrainment profiles, in particular with spacers between the sieve elements, are provided. The means mentioned are in particular holding members at the ends of the preferably rod-shaped driving profiles, such as clamping screws or the like.

Durch die Mittel zum axialen Zusammenpressen der Siebelemente auf der Siebwelle und/oder die Mittel zum axialen Zusammenpressen der Siebelemente entlang der Mitnehmerprofile wird die Drehmomentübertragung von der Siebwelle auf die Siebelemente auf mehrere Arten unterstützt und verbessert. Zum einen kann ein Klemmeffekt die Folge sein. Die zusammengepressten Siebelemente und Distanzstücke üben mehr Druck auf die Siebwelle aus. Zum anderen sind die Siebelemente und Distanzstücke miteinander stärker verbunden, sodass einzelne Siebelemente nicht durchrutschen können. Dieser Effekt wird insbesondere durch die Mitnehmerprofile erreicht, die aber auch die Klemmwirkung verstärken können.By means for axially compressing the screen elements on the screen shaft and / or the means for axially compressing the screen elements along the flight profiles, the torque transmission from the screen shaft to the screen elements is aided and improved in several ways. On the one hand, a clamping effect can be the result. The compressed sieve elements and spacers exert more pressure on the screen shaft. On the other hand, the sieve elements and spacers are connected to each other stronger, so that individual sieve elements can not slip. This effect is achieved in particular by the Mitnehmerprofile, but can also enhance the clamping action.

Gegenstand der Erfindung ist auch ein Stern- oder Scheibensieb mit Siebelementen und/oder Siebwellen entsprechend den voranstehenden Ausführungen.The invention also relates to a star or disk screen with sieve elements and / or screen shafts according to the preceding embodiments.

Ein Siebstern 15 weist umlaufend aufeinanderfolgende Arme oder Zacken 16 auf, die abweichend von der radialen Richtung ausgerichtet und/oder gekrümmt sein können und hier jeweils gleich lang sind. Radial innerhalb der Zacken 16, in einem mittleren Bereich 17, ist der Siebstern 15 mit einem mittigen Durchlass 18 zur Aufnahme einer Vierkant-Siebwelle versehen. Entsprechend ist der mittige Durchlass 18 mit quadratischem Querschnitt ausgebildet. Lediglich Eckbereiche sind leicht gerundet.A screen star 15 has circumferentially successive arms or prongs 16, which can be aligned and / or curved differently from the radial direction and are each equal in length here. Radially within the serrations 16, in a central region 17, the screen star 15 is provided with a central passage 18 for receiving a square screen shaft. Accordingly, the central passage 18 is formed with a square cross-section. Only corner areas are slightly rounded.

Zusätzlich weist der mittlere Bereich 17 außermittige Durchlässe 19 auf, nämlich mit gleichen Abständen zueinander und etwa mit gleicher Distanz zum mittigen Durchlass 18 einerseits und zu den benachbarten Zacken 16 andererseits.

Der Siebstern 15 ist aus Gummi oder Polyuretten (PU) oder einem anderen gummiartigen oder ähnlich elastischen Material hergestellt.The Siebstern 15 is made of rubber or Polyuretten (PU) or other rubbery or similar elastic material.

Ein Distanzstück 20 ist gemäß Fig. 4 scheibenförmig ausgebildet, im Gegensatz zum Siebstern 15 aber ohne Zacken, und weist einen mittigen Durchlass 21 und außermittige Durchlässe 22 auf, deren Anordnung und Abmessungen mit den Durchlässen 18, 19 des Siebsterns 15 korrespondieren. Der Außendurchmesser des Distanzstücks 20 entspricht ungefähr dem Außendurchmesser des mittleren Bereichs 17 am Siebstern 15.A spacer 20 is according to Fig. 4 disc-shaped, in contrast to the Siebstern 15 but without spikes, and has a central passage 21 and off-center passages 22, whose arrangement and dimensions with the passages 18, 19 of the screen star 15 correspond.

Genau genommen ist zwischen je zwei Siebsternen 15 genau ein Distanzstück 20 angeordnet. Außerdem sind äußere Siebsterne abgedeckt durch äußere Distanzstücke 24, 25. Gehalten sind die Siebsterne 15 und Distanzstücke 20, 24, 25 auf der Siebwelle 23 durch den zu den mittigen Durchlässen 18, 21 passenden Außenquerschnitt der Siebwelle 23. Hier sollten möglichst kein Spiel und kein Schlupf vorhanden sein. Zumindest die Siebsterne 15 sollten klemmend auf der Siebwelle 23 sitzen.According to the Fig. 7 to 9 are on a square screen shaft 23 side by side a plurality of screen stars 15 provided with spacers 20 disposed therebetween. Strictly speaking, exactly one spacer 20 is arranged between each two screen stars 15. In addition, outer screen stars are covered by outer spacers 24, 25th Held are the screen stars 15 and spacers 20, 24, 25 on the screen shaft 23 through the central to the passages 18, 21 matching outer cross section of the screen shaft 23.

Außerdem sind die Siebsterne 15 und Distanzhülsen 20, 24, 25 durch stangenförmige Mitnehmerprofile 26 verbunden, welche durch die außermittigen Durchlässe 19, 22 gesteckt sind. An freien Enden der Mitnehmerprofile 26 sind Gewinde vorgesehen mit Klemmmuttern 27. Diese werden angezogen, sodass die Siebsterne 15 und Distanzstücke 20, 24, 25 auf der Siebwelle 23 in axialer Richtung gepresst werden.In addition, the screen stars 15 and spacers 20, 24, 25 are connected by rod-shaped Mitnehmerprofile 26, which are inserted through the off-center passages 19, 22. At free ends of the Mitnehmerprofile 26 threads are provided with clamping nuts 27. These are tightened so that the screen stars 15 and spacers 20, 24, 25 are pressed on the screen shaft 23 in the axial direction.

Die beschriebene Konstruktion mit den flachen Siebsternen 15 und den ebenfalls flachen, scheibenförmigen Distanzstücken 20 ist kostengünstig und kann ein hohes Drehmoment übertragen, obwohl die Siebsterne keine axial überstehende Nabe aufweisen. Das Drehmoment wird zum einen von der Siebwelle 23 über die Distanzstücke 20 und die Mitnehmerprofile 26 auf die Siebsterne 15 übertragen. Zum anderen verbessert die klemmende Anordnung die direkte Drehmomentübertragung von der Siebwelle auf die Siebsterne, von der Siebwelle auf die Distanzstücke und von den Distanzstücken auf die Siebsterne.The construction described with the flat screen stars 15 and the also flat disc-shaped spacers 20 is inexpensive and can transmit a high torque, although the screen stars have no axially projecting hub. The torque is transmitted on the one hand of the screen shaft 23 via the spacers 20 and the Mitnehmerprofile 26 on the screen stars 15. On the other hand, the clamping arrangement improves the direct transmission of torque from the screen shaft to the screen stars, from the screening shaft to the spacers and from the spacers to the screen stars.

Die Fig. 10 bis 12 zeigen eine Abwandlung zu den Fig. 7 bis 9. Die Siebwelle ist nicht eingezeichnet. Die Distanzstücke sind nur etwa halb so dick (in axialer Richtung) ausgebildet wie in Fig. 7. Zum Ausgleich sind jeweils zwei Distanzstücke 28 zwischen zwei benachbarten Siebsternen 15 vorgesehen. Außerdem sind jeweils vor den äußeren Siebsternen drei Distanzstücke 29, 30 vorgesehen. Im Übrigen weisen die Distanzstücke 28, 29, 30 die gleichen Eigenschaften und Durchlässe wie die Distanzstücke 20 auf.The 10 to 12 show a modification to the Fig. 7 to 9 , The sieve shaft is not shown. The spacers are only about half as thick (in the axial direction) formed as in Fig. 7 , To compensate for two spacers 28 between two adjacent screen stars 15 are provided. In addition, three spacers 29, 30 are provided in each case before the outer screen stars. Incidentally, the spacers 28, 29, 30 have the same properties and passages as the spacers 20.

In der Ausführung der Fig. 10 bis 12 weisen die Distanzstücke 28 bis 30 ungefähr dieselbe axiale Dicke wie die Siebsterne 15 auf.In the execution of 10 to 12 the spacers 28 to 30 have approximately the same axial thickness as the screen stars 15.

Die Distanzstücke 20, 24, 25, 28, 29, 30 können aus demselben Werkstoff hergestellt sein wie die Siebsterne 15. Vorzugsweise sind die Distanzhülsen aber aus einem härteren Werkstoff hergestellt, etwa aus Metall oder einem hochfesten Kunststoff.The spacers 20, 24, 25, 28, 29, 30 may be made of the same material as the screen stars 15. Preferably, however, the spacers are made of a harder material, such as metal or a high-strength plastic.
