Description

Die Erfindung betrifft eine Scheibe für ein Scheibensieb oder einen Scheibenseparator, welches mehrere parallel in einem Gestell angeordnete, drehfest antreibbare Wellen aufweist, auf denen mehrere solcher Scheiben auf Lücke und ineinandergreifend angeordnet sind, mit einem Scheibenkörper, der einen als Vieleck gestalteten Umfang, zwei Seitenflächen und eine der Anzahl der Ecken des Vieleckes entsprechende Anzahl von Teilflächen am Umfang aufweist und aus einem Eisenwerkstoff besteht.The invention relates to a disc for a disc screen or a disc separator, which several in parallel in a frame arranged, rotatably drivable shafts on which several such disks on gap and interlocking are arranged, with a disk body, the one as a polygon designed perimeter, two side faces and one of the number of Corners of the polygon corresponding number of partial areas on the circumference has and consists of an iron material.

Solche Scheibensiebe oder Scheibenseparatoren (DE 44 08 903 A1) eignen sich insbesondere zum Trennen schwer siebfähiger Massen. Sie weisen, verglichen mit anderen Sieben, eine hohe Kapazität im Verhältnis zu ihrer Baugröße auf. Bevorzugt werden mehreckige Scheiben, z.B. mit sechs, acht oder zehn Ecken, gewählt, durch die eine verbesserte Aufschließung des Siebgutes erfolgt. Ein bindiges Siebgut hat die Tendenz, sich an den Scheiben oder auf den Wellennaben festzusetzen und aufzubauen. Um dies zu verhindern, werden Abstreifer vorgesehen. Die vieleckige Ausführung der Scheiben ist erforderlich, um das Gut auf den Scheiben weiter in Richtung der nächsten Scheiben zu transportieren. Die Scheibenecken sorgen auch dafür, daß eine günstige Aufschließung erfolgt. Durch die schnell rotierenden vieleckigen Scheiben wird die zu behandelnde Masse verwirbelt, wodurch eine starke Volumenvergrößerung entsteht. Bei der Behandlung von Böden wird so eine günstige Voraussetzung für die Aufnahme von Mitteln erzielt, um beispielsweise die Verweildauer des Bodens auf Mieten zur Be-handlung wesentlich zu reduzieren. Darüber hinaus können solche Scheibensiebe bzw. -separatoren genutzt werden, um eine bestimmte Korngröße zu erschließen. Die Verwirbelung sorgt auch dafür, daß ein guter Mischeffekt erzielt wird. Von Nachteil ist jedoch, daß die Ecken sich schnell abnutzen, je nachdem was für ein Ma-terial zu verarbeiten ist. Dies bedeutet hohe Wartungskosten und Stillstandszeiten bzw. eine Verschlechterung der Funktionsweise.Such disc sieves or disc separators (DE 44 08 903 A1) are particularly suitable for separating masses that are difficult to screen. They have a high capacity compared to other seven in relation to their size. Polygonal are preferred Disks, e.g. with six, eight or ten corners, chosen by an improved disintegration of the screenings takes place. A Cohesive screenings have a tendency to stick to the discs or on to fix and build up the shaft hubs. To prevent this, wipers are provided. The polygonal version The slices are required to continue the good on the slices in the direction of the next slices. The Disc corners also ensure that a favorable unlocking he follows. Due to the rapidly rotating polygonal discs the mass to be treated swirls, causing a large increase in volume arises. So when treating floors a favorable condition for raising funds, for example the length of time the floor stays on rents to reduce treatment significantly. In addition, you can such disc sieves or separators are used to a to develop certain grain size. The swirling also provides that a good mixing effect is achieved. The disadvantage is however, that the corners wear out quickly, depending on what a material is to be processed. This means high maintenance costs and downtimes or worsening of Functionality.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Scheibe für ein Scheibensieb oder einen Scheibenseparator vorzuschlagen, welche geeignet ist, auch für eine lange Nutzungsdauer die gewünschte Arbeitsweise zu gewährleisten, d.h. bei der die Ursprungsgeometrie über einen großen Zeitraum erhalten bleibt.The invention is therefore based on the object of a disc propose a disc sieve or a disc separator, which is suitable, the desired one even for a long service life To ensure the way of working, i.e. where the original geometry over a long period of time.

Dieser Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens eine der Teilflächen des Scheibenkörpers mit einer Panzerung aus Hartmetall versehen ist, welche eine zugehörige Ecke umfaßt und sich zumindest über einen Teil der Länge der Teilfläche erstreckt.This object is achieved in that at least one of the sub-areas of the disk body with armor is made of hard metal, which has an associated corner comprises and extends over at least part of the length of the partial area extends.

Von Vorteil bei dieser Ausbildung ist, daß die Ecken über eine lange Lebensdauer ausgeprägt erhalten bleiben, da das Hartmetall gegen Abtragung weitgehend resistent ist. Damit bleibt auch über eine lange Lebensdauer ein guter Durchmischungseffekt beim Einsatz gewährleistet.The advantage of this training is that the corners have a long lifespan is clearly preserved because of the hard metal is largely resistant to ablation. That also remains a long service life a good mixing effect when used guaranteed.

In einer bevorzugten Ausführungsform ist die Ausbildung der Panzerung in Form von Plattenelementen vorgesehen, die aus Hartmetall bestehen und am Scheibenkörper befestigt sind. Als bevorzugtes Hartmetall kommt ein solches mit 80 bis 90 % Wolframcarbit und mit Kobalt- oder Nickelbinder in Frage. Alternativ ist vorgesehen, die Panzerung aus Hartmetallsplitt herzustellen, der mit der Teilfläche durch ein Lot verbunden ist. Durch eine solche Ausbildung kann die Verwirbelung noch verbessert werden, da die einzelnen Hartmetallsplittelemente mit ihren Spitzen wirksam werden und so noch das Aufschließen verbessern.In a preferred embodiment, the armor is formed provided in the form of plate elements made of hard metal exist and are attached to the disc body. As a favorite Tungsten carbide comes with 80 to 90% tungsten carbite and with cobalt or nickel binder in question. Alternative is intended to manufacture the armor from hard metal chips, the is connected to the partial area by a solder. By such Training, the swirling can be improved because the individual hard metal split elements with their tips effective and thus improve the unlocking.

Vorzugsweise schließt die Panzerung ausgehend von einer Ecke auch die von dieser ausgehenden Teilflächen zumindest über eine Teillänge derselben ein. Es ist jedoch auch möglich, die Teilflächen über ihre Gesamtlänge jeweils mit einer Panzerung zu versehen.The armor preferably closes from a corner also the partial areas emanating from this at least over one Partial length of the same. However, it is also possible to use the partial areas along their entire length with armor Mistake.

Für eine weitere Ausführungsform nach der Erfindung ist vorgesehen, daß der Scheibenkörper eine gerade Anzahl von Ecken aufweist, daß in Richtung des Umfangs des Scheibenkörpers jede zweite Ecke mit einem Abstreifer versehen ist, der mindestens einseitig über eine der Seitenflächen des Scheibenkörpers vorsteht und daß die jeweils dazwischen angeordneten Teilflächen zu den nicht mit Abstreifern versehenen Ecken hin die Panzerung aufweisen.For a further embodiment according to the invention, that the disc body has an even number of corners, that in the direction of the circumference of the disc body each second corner is provided with a scraper that at least protrudes unilaterally over one of the side surfaces of the disk body and that the sub-areas arranged between them too the armor towards the corners not provided with wipers exhibit.

Für den Fall, daß Hartmetallsplitt vorgesehen ist, wird vorzugsweise solcher mit einer Korngröße von 0,6 bis 1,8 mm gewählt. Für die Verbindung von Hartmetallsplitt mit dem aus Stahl bzw. einem Eisenwerkstoff bestehenden Scheibenkörper ist ein Lot auf Kupfer- oder Nickelbasis vorgesehen. Dessen Schmelzpunkt liegt in der Größenordnung von 1.120° C. Eine innige Verbindung zwischen dem Hartmetallsplitt und den Teilflächen des Scheibenkörpers wird vorzugsweise durch Verlöten unter Vakuum erzielt. Als Werkstoff für den Scheibenkörper kommt beispielsweise ein Stahl der Qualität 42CrMo4 oder 50CrVMo4 in Frage.In the event that hard metal chippings are provided, it is preferred those with a grain size of 0.6 to 1.8 mm selected. For the connection of hard metal chips with the steel or an iron disc material is soldered on Copper or nickel base provided. Whose melting point is of the order of 1,120 ° C. An intimate connection between the hard metal chips and the partial surfaces of the disc body is preferably achieved by soldering under vacuum. As For example, a material for the disc body comes from steel the quality 42CrMo4 or 50CrVMo4 in question.

Ein Scheibensieb bzw. ein Scheibenseparator und zwei Ausführungsformen einer Scheibe sind in der Zeichnung schematisch dargestellt und anhand derselben näher erläutert.A disk sieve or a disk separator and two embodiments a disk are shown schematically in the drawing and explained in more detail using the same.

Das Scheibensieb bzw. der Scheibenseparator gemäß Figuren 1 und 2 umfaßt ein Gestell 1, in dem im parallelen Abstand Wellen 2 drehbar angeordnet sind. Die Wellen 2 tragen jeweils Scheiben 3, die auf Lücke stehend durch Abstandshülsen gehalten sind. Die Scheiben 3 sind drehfest mit den zugehörigen Wellen 2 verbunden. Die Scheiben jeweils zweier benachbarter Wellen greifen gegenseitig in die Lücken zwischen zwei einer Welle zugeordneten Scheiben 3 ein.The disc screen or the disc separator according to Figures 1 and 2 comprises a frame 1, in which waves 2 at a parallel distance are rotatably arranged. The shafts 2 each carry disks 3, which are held in a gap by spacer sleeves. The Disks 3 are rotatably connected to the associated shafts 2. The disks of two adjacent shafts engage each other in the gaps between two assigned to a wave Discs 3 a.

Aus Figur 2 ist ersichtlich, daß die Scheiben 3 mehreckig ausgebildet sind. Die Scheiben 3 weisen jeweils im Bereich mehrerer Ecken Abstreifer 5 auf, die zumindest von einer ihrer Seitenflächen vorstehen. Diese dienen dazu, an den Seitenflächen der gegenüberliegenden Scheiben 3 anhaftendes Gut abzustreifen. Die Wellen 2 werden durch einen Antrieb 4 drehend angetrieben. Hierzu dienen beispielsweise Ketten- oder Riementriebe, durch die zwangsweise eine Synchronisierung der Rotation der Wellen 2 untereinander erzeugt wird, damit die von den Seitenflächen vorstehenden Abstreifer 5 sich nicht gegenseitig berühren können. Die Scheiben 3 werden in einer Richtung drehend angetrieben, so daß das Gut von einem Aufgabeende, beispielsweise im Bereich der rechts am Gestell 1 angeordneten Welle in Richtung der links am Gestell angeordneten letzten Welle hin aufgrund der mehreckigen Ausführung der Scheiben transportiert und auf diesem Wege aufgeschlossen und gesiebt wird, so daß es durch die Lücken zwischen den ineinandergreifenden Scheiben 3 fallen kann.From Figure 2 it can be seen that the discs 3 are polygonal are. The disks 3 each have several Corners wipers 5 on at least one of their side surfaces protrude. These are used on the side surfaces of the to strip opposite discs 3 adhering material. The Shafts 2 are driven in rotation by a drive 4. For this serve for example chain or belt drives through which forced synchronization of the rotation of the shafts 2 with each other is generated so that the protruding from the side surfaces Wipers 5 can not touch each other. The disks 3 are driven to rotate in one direction, so that the goods from one task end, for example in the area of arranged on the right of frame 1 in the direction of the left on Last shaft arranged due to the polygonal frame Execution of the discs transported and unlocked in this way and is sifted so that it passes through the gaps between the interlocking discs 3 can fall.

Um den Verschleiß bzw. die Wirkung der Ecken der Scheiben 3 über eine lange Zeit aufrechtzuerhalten, sind die Scheiben 3 im Bereich der Ecken und ihrer daran angrenzenden Flächen zumindest teilweise mit einer Panzerung versehen, die aus den Figuren 1 und 2 nicht ersichtlich ist, anhand der Figuren 3 und 4 für zwei Ausführungsformen jedoch näher erläutert ist.To the wear or the effect of the corners of the discs 3 over to maintain a long time, the disks 3 are in the area the corners and their adjacent surfaces at least partially provided with armor, which is shown in FIGS and 2 is not apparent, based on Figures 3 and 4 for two However, embodiments are explained in more detail.

Figur 3 zeigt eine Scheibe 3' für den Einsatz in einem Scheibenseparator bzw. einem Scheibensieb gemäß Figuren 1 und 2, dessen Scheibenkörper 6 auf dem Umfang zehneckig ausgebildet ist, also zehn Ecken 8 besitzt, zwischen denen jeweils Teilflächen 9 angeordnet sind. Eine der Seitenflächen ist erkennbar und mit 10 bezeichnet. Im Zentrum des Scheibenkörpers 6 ist ein Durchbruch 7 angeordnet, mit dem die Scheibe 3' drehfest auf einer der Wellen des Scheibensiebes bzw. Scheibenseparators festgelegt werden kann. Es ist eine gerade Anzahl von Ecken 8 vorgesehen. Entsprechend ist auch eine gerade Anzahl von zehn Teilflächen 9 vorhanden. Über den Umfang gesehen, ist jede zweite Ecke 8 mit einem Abstreifer 5 versehen, der zumindest von der Teilfläche 10, d.h. aus der Zeichenebene vorsteht. Solche Abstreifer 5 können beispielsweise selbst zumindest teilweise aus einem Hartmetall be-stehen. Im Bereich der nicht mit Abstreifern 5 besetzten Ecken 8 sind im Scheibenkörper 6 Ausnehmungen vorhanden, in welche Plattenelemente 11 aus Hartmetall eingesetzt sind, die die Ecken 8 umfassen und sich jeweils ausgehend von einer Ecke 8 über eine Teillänge der anschließenden und in Richtung auf die mit Ab-streifern 5 besetzten Ecken 8 verlaufenden Teilflächen 9 erstrecken. Die Plattenelemente 11 haben im wesentlichen die Dicke des Scheibenkörpers 6 und sind mit diesem durch ein Lot oder dergleichen Mittel unlösbar verbunden. Es genügt für einige Anwendungsfälle, wenn von den jeweils zu einer Ecke 8 gehörenden zwei Teilflächen 9 nur eine mit einem Plattenelement 11 versehen ist, welches die Ecke 8 einschließt.FIG. 3 shows a disk 3 'for use in a disk separator or a disc sieve according to Figures 1 and 2, the Washer body 6 is formed on the circumference, ie has ten corners 8, between which partial areas 9 are arranged are. One of the side faces is recognizable and with 10 designated. There is an opening in the center of the disk body 6 7 arranged with which the disc 3 'rotatably on one of the shafts of the disc sieve or disc separator can. An even number of corners 8 is provided. Corresponding is also an even number of ten faces 9 available. Seen over the circumference, every second corner is 8 a scraper 5 provided, at least from the partial area 10, i.e. protrudes from the drawing level. Such wipers 5 can, for example, themselves at least partially from a hard metal consist. In the area of the wipers 5 not occupied Corners 8 are 6 recesses in the disc body, in which plate elements 11 made of hard metal are used, the embrace the corners 8 and each start from a corner 8 over a partial length of the subsequent and towards the partial stripes 9 with scraper 5 occupied corners 8 extend. The plate elements 11 have essentially Thickness of the disk body 6 and are with this by a solder or similar means inextricably linked. It is enough for some Use cases if of the 8 belonging to a corner two partial surfaces 9 are only provided with a plate element 11 which includes corner 8.

Für eine Ausbildung der Scheibe 3' ohne Abstreifer 5 ist es auch möglich, sämtliche Ecken 8 mit einer Panzerung in Form der Plattenelemente 11 zu versehen. Darüber hinaus besteht auch die Möglichkeit, die Plattenelemente 11 so weit zu führen, daß sie sich über die gesamten Teilflächen 9 erstrecken bzw. für den Fall, daß Abstreifer 5 vorhanden sind, bis zu diesen reichen.It is also possible for the disc 3 'to be formed without a scraper 5 possible, all corners 8 with armor in the form of the plate elements 11 to be provided. In addition, there is also the possibility to guide the plate elements 11 so far that they are extend over the entire partial areas 9 or in the event that wipers 5 are present, reach up to these.

Figur 4 zeigt eine alternative Ausführungsform zu der gemäß Figur 3. Die Scheibe 3'' ist ebenfalls als Zehneck gestaltet, d.h. sie weist zehn Ecken 8 auf, die jeweils durch Teilflächen 9 verbunden sind. An jeder zweiten Ecke ist wiederum ein Abstreifer 5 angebracht. Die zwischen zwei Abstreifern 5 auf dem Umfang liegenden freien Ecken 8 sind mit einer Panzerung in Form von Hartmetallsplitt 12 versehen. Die Teilflächen 9 sind ausgehend jeweils von einer Ecke 8, die in die Panzerung einbezogen ist, d.h. ebenfalls mit Hartmetallsplitt 12 bestückt ist, zumindest über eine Teillänge der Teilflächen 9 in Richtung zu der Ecke 8, die mit einem Abstreifer 5 besetzt ist, mit Hartmetallsplitt versehen. Der Hartmetallsplitt 12 weist vorzugsweise eine Körnung von 0,6 bis 1,8 mm auf und ist mit den Teilflächen 9, d.h. mit dem Grundwerkstoff des Scheibenkörpers 6', durch ein Lot verbunden. Vom Grundaufbau her entspricht der Scheibenkörper 6' dem Scheibenkörper 6, so wie er im Zusammenhang mit Figur 3 beschrieben ist, wobei jedoch die Ecken 8 im Scheibenkörper 6' ausgebildet sind. Unter Hartmetallsplitt versteht man körniges Material aus Hartmetall. Dabei weist dies für den vorbeschriebenen Anwendungsfall die oben näher bezeichnete Korngröße bevorzugt auf. Durch die Anordnung ist ebenfalls gewährleistet, daß die Ecken 8 wirksam geschützt sind. Dies bedeutet, daß die Ecken 8 einem wesentlich verringerten Verschleiß unterliegen und durch die grobe Struktur darüber hinaus sägeartig auf das zu behandelnde Material beim Einsatz in einem Scheibenseparator bzw. Scheibensieb einwirken und dieses wirksam aufschließen. Ferner wird der Transport des Gutes hierdurch positiv beeinflußt.FIG. 4 shows an alternative embodiment to that according to FIG 3. The disc 3 '' is also designed as a decagon, i.e. it has ten corners 8, each connected by partial surfaces 9 are. There is a scraper at every second corner 5 attached. The between two scrapers 5 on the circumference lying free corners 8 are with armor in the form of Carbide chips 12 provided. The partial areas 9 are outgoing each from a corner 8, which is included in the armor, i.e. is also equipped with hard metal chips 12, at least over a partial length of the partial areas 9 in the direction of the corner 8, which is equipped with a scraper 5, with hard metal chips Mistake. The hard metal chips 12 preferably have a grain size from 0.6 to 1.8 mm and is with the partial surfaces 9, i.e. with the base material of the disk body 6 ', by a solder connected. The basic structure of the disk body corresponds to 6 ' the disk body 6, as described in connection with Figure 3 is, however, the corners 8 in the disc body 6 ' are trained. Hard metal chippings are granular Tungsten carbide material. This indicates for the above Use the grain size specified above preferred on. The arrangement also ensures that the corners 8 are effectively protected. This means that the corners 8 subject to significantly reduced wear and tear the rough structure is also saw-like on the item to be treated Material when used in a disc separator or Act on the screen sieve and open it effectively. Further this has a positive effect on the transport of the goods.

Ein Besatz, d.h. Panzerung, der weiteren Ecken 8 im Bereich der Abstreifer 5 ist dann nicht erforderlich, wenn diese beispielsweise zumindest teilweise ebenfalls aus einem Hartmetall bestehen und dadurch der Verschleiß des Scheibenkörpers 6' auch in diesem Bereich wirksam herabgesetzt ist. A stocking, i.e. Armor, the other corners 8 in the area of Scraper 5 is not required if, for example at least partially also consist of a hard metal and thereby the wear of the disk body 6 'also in this area is effectively reduced.
