Description

Die Erfindung betrifft eine Siebvorrichtung, insbes. für das Aussieben von unterschiedlichen Materialien wie Hausmüll, Kompost oder dergl., bei der zwischen den Seitenwänden eines Rahmens bzw. an einem Gestall Träger angeordnet sind, an denen einzeln oder in Gruppen abnehmbar und/ oder verschiebbar angebrachte Siebstäbe einseitig gehalten sind.The invention relates to a screening device, in particular for the screening out of different materials such as household waste, compost or the like, in which supports are arranged between the side walls of a frame or on a frame, on which, individually or in groups, can be removed and / or slidably attached Sieve bars are held on one side.

Siebvorrichtungen mit Stabrosten, bei denen die mit Abstand nebeneinanderliegenden Stäbe nur an der Aufgabeseite eingespannt sind und auf der Abgabeseite völlig frei liegen sind bekannt. Insbesondere durch die freiliegenden Enden der Stäbe können diese Siebroste nicht verstopfen und sind deshalb besonders gut für schwierige Siebvorgänge geeignet, wie sie z. B. bei Hausmüll mit seiner Zusammensetzung aus unterschiedlichsten z.T. auch klebrigen Materialien gegeben sind.Screening devices with bar grids, in which the bars lying next to one another at a distance are clamped only on the feed side and are completely exposed on the delivery side are known. In particular, due to the exposed ends of the rods, these sieve grids cannot become clogged and are therefore particularly well suited for difficult sieving processes, such as, for. B. with household waste with its composition of different partly. sticky materials are also given.

Nachteilig bei den bekannten Siebvorrichtungen dieser Art ist, daß sie nur schwer an unterschiedliche Zusammensetzungen und damit Betriebserfordernisse des zu sortierenden Gutes anpaßbar sind, da die Stabroste, wie sie beispielsweise aus der US-A-3 241 671 bekannt sind, in die Siebvorrichtungen in der Regel starr eingebaut sind.A disadvantage of the known screening devices of this type is that they are difficult to adapt to different compositions and thus the operating requirements of the goods to be sorted, since the bar grates, as are known, for example, from US Pat. No. 3,241,671, into the screening devices in the Usually rigidly installed.

Zwar sind in der Zeitschrift «Aufbereitungstech- nik" Band 22 Nr. 7 vom Juli 1981 insbesondere auf Seite 396 allgemeine Hinweise gegeben, daß durch eine variable Stangenanbringung an den Siebvorrichtungen eine größere Variabilität erreicht werden kann. Jedoch fehlt es dabei an konkreten Merkmalen zur Erreichung des gewünschten Erfolges.In the journal "Processing Technology " Volume 22 No. 7 of July 1981, in particular on page 396 there are general indications that greater variability can be achieved by variable rod attachment to the screening devices. However, there are no concrete features to achieve this of the desired success.

Durch die vorliegende Erfindung soll deshalb die Aufgabe gelöst werden, eine Siebvorrichtung für den eingangs genannten Zweck zu schaffen, die in kürzester Zeit mit einfachen Mitteln an unterschiedlichste Beschaffenheit des Sortiergutes anpaßbar ist und somit eine optimale Ausnutzung der Siebvorrichtung ermöglicht.The present invention is therefore intended to achieve the object of creating a screening device for the purpose mentioned at the outset, which can be adapted in a very short time to the most varied properties of the goods to be sorted using simple means and thus enables optimum use of the screening device.

Zur Lösung dieser Aufgabe wird erfindungsgemäß eine Siebvorrichtung vorgeschlagen, bei der die an den schwenkbar an den Seitenwänden bzw. an dem Gestell gelagerten Trägern angebrachten Siebstäbe in als Prismen- oder Halbrundführungen ausgebildeten Tragorganen gehalten sind, die unter Klemmschienen greifende Fußteile aufweisen, wobei die Klemmschienen mit sich über die Länge der Träger erstreckenden Auskragungen verbindbar sind.To achieve this object, a sieve device is proposed according to the invention, in which the sieve bars attached to the supports which are pivotably mounted on the side walls or on the frame are held in support members which are designed as prismatic or semicircular guides and which have foot parts engaging under the clamping rails, the clamping rails also projections extending over the length of the beams are connectable.

Die Siebstäbe können dabei fest mit den Tragorganen verbunden sein. Zweckmäßig sollen sie aber in den Prismen- oder Halbrundführungen mittels lösbarer Klemmvorrichtungen in der Längsrichtung der Stäbe verschiebbar oder auch abnehmbar gehalten sein.The sieve bars can be firmly connected to the support members. Expediently, however, they should be slidable or detachable in the prism or semicircular guides by means of releasable clamping devices in the longitudinal direction of the rods.

Die Führungen der Tragorgane der Siebstäbe können für benachbarte Stäbe mit unterschiedlichen Neigungen ausgeführt sein, so daß benachbarte Stäbe zu ihren freien Enden hin divergieren wodurch sich erweiternde oder verengende Siebschlitze geschaffen werden. Es ist auch möglich, die unterschiedlichen Neigungen der Siebstäbe durch einfaches Drehen der Tragorgane um 180° einzustellen, wobei dann nur eine einzige Ausführungsform von Tragorganen für zwei unterschiedliche Stabneigungen erforderlich ist.The guides of the support members of the sieve bars can be designed for adjacent bars with different inclinations, so that adjacent bars diverge towards their free ends, creating widening or narrowing screen slots. It is also possible to adjust the different inclinations of the sieve bars by simply rotating the support members through 180 °, in which case only a single embodiment of support members is required for two different rod inclinations.

In der Regel sind die Siebstäbe als Rundstäbe oder -rohre ausgeführt, sie können aber auch Dreikant- oder ähnlich geformte Stäbe sein, die in der Weise angeordnet sind, daß sich die Öffnungen zwischen benachbarten Stäben unterhalb der Aufgabeseite des Siebgutes erweitern, was zur Folge hat, daß durch die Siebschlitze hindurchgetretenes Gut nicht mehr hängen bleiben kann.As a rule, the sieve bars are designed as round bars or tubes, but they can also be triangular or similarly shaped bars which are arranged in such a way that the openings between adjacent bars widen below the feed side of the material to be sieved, with the result that material that has passed through the sieve slots can no longer get caught.

Bei einer Siebvorrichtung dieser Art können mehrere Träger mit Reihen von Siebstäben zwischen den Seitenwänden des Rahmens bzw. am Gestell untereinander, gegebenenfalls versetzt zueinander angebracht sein. Es ist auch möglich Träger mit Reihen von Siebstäben und Siebgewebe an sich bekannter Art in Kombination vorzusehen.In the case of a screening device of this type, a plurality of supports with rows of screening bars can be arranged between the side walls of the frame or on the frame with one another, optionally offset from one another. It is also possible to provide supports in combination with rows of sieve bars and sieve fabrics in a manner known per se.

Der Rahmen, an dem die Träger für die Siebstäbe mit ihren Tragorganen, sowie gegebenenfalls die zusätzlichen Siebböden fest angebracht sind, kann mit einer für die Siebböden gemeinsamen Vibrationsvorrichtung verbunden sein.The frame, on which the supports for the sieve bars with their supporting members, and optionally the additional sieve trays, are firmly attached, can be connected to a vibration device common to the sieve trays.

Bei einer Siebvorrichtung mit an einem Gestell gelagerten Trägern, kann die Vorrichtung nach dem Baukastensystem beliebig erweitert werden, indem nur das Gestell erweitert wird und immer gleiche Träger mit den Sieb- und Schwingungseinheiten zusätzlich am Gestell angebracht werden.In the case of a screening device with supports mounted on a frame, the device can be expanded as desired according to the modular system, in that only the frame is expanded and the same supports are always attached to the frame with the screening and vibration units.

In Fig. 1 ist mit 10 eine Seitenwand bezeichnet. Zwischen jeweils zwei von derartigen Seitenwänden sind Träger 12 für die Stäbe 13 angeordnet, wobei die Figur jeweils eine obere Stabreihe und eine untere Stabreihe erkennen läßt. An den Seitenwänden 10 ist eine Rütteleinrichtung 11 in an sich bekannter Weise angeordnet. Oberhalb der Befestigung der Stäbe 13 an den Trägern 12 sind Abdeckbleche 15, 16 vorgesehen, durch die verhindert werden soll, daß sich Schmutz, Müll oder dergl. an den Befestigungen der Stäbe an den Trägern festsetzt.In Fig. 1, 10 denotes a side wall. Carriers 12 for the bars 13 are arranged between two of such side walls, the figure showing an upper row of bars and a lower row of bars. A vibrating device 11 is arranged on the side walls 10 in a manner known per se. Above the attachment of the rods 13 to the supports 12, cover plates 15, 16 are provided, by means of which dirt, garbage or the like. Fixes on the fastenings of the rods on the supports.

Unterhalb der Siebstabreihen ist bei dem Ausführungsbeispiel der Erfindung gemäß Fig. 1 noch ein Siebboden 27 angeordnet, bei dem an jedem Ende des Siebgewebes falzartig angeformte Bleche 28 befestigt sind, die eingehakt und mit einer Spannvorrichtung verbunden werden. Im Mittelteil des Siebbodens können noch Unterstützungsrohre 29 zur Abstützung des Siebgewebes vorgesehen werden.Below the sieve rows, in the embodiment of the invention according to FIG. 1, a sieve bottom 27 is also arranged, in which sheets 28 which are shaped like folds are fastened to each end of the sieve fabric and are hooked on and connected to a tensioning device. In the middle part of the sieve bottom support tubes 29 can be provided to support the sieve fabric.

Durch die dargestellte Kombination wird erreicht, daß durch die Stäbe sperriges Material und auch faseriges Material wie Lappen, Plastiktüten oder dergl. zurückgehalten werden und nicht den Siebboden verstopfen. Andererseits können lange schmale Gegenstände, die zwischen den Stäben durchfallen könnten noch vom Siebboden aufgefangen werden.The combination shown ensures that bulky material and fibrous material such as rags, plastic bags or the like are retained by the rods and do not clog the sieve bottom. On the other hand, long narrow objects that could fall through between the bars can still be caught by the sieve bottom.

Bei dem in Fig. 2 dargestellten Träger 12, sind an den Stirnseiten einer quadratischen Rohrkonstruktion 19 Scheiben 18 angebracht, mit denen der Träger an den Seitenwänden der Siebvorrichtung gehalten und gelagert werden kann. Am oberen Teil der Rohrkonstruktion 19 sind Auskragungen 20 angeschweißt, so daß sich dort eine breite Auflagefläche für die Tragorgane 17 für die Stäbe 13 ergibt. In den Auskragungen 20 befinden sich über die ganze Trägerlänge verteilt Bohrungen 21, durch die Schrauben 25 hindurchführbar sind, die in Klemmschienen 22 eingreifen. Mit diesen Klemmschienen werden die Tragorgane 17 für die Stäbe 13 am Träger 12 festgehalten.In the support 12 shown in Fig. 2, 19 discs 18 are attached to the end faces of a square tubular structure, with which the support can be held and stored on the side walls of the screening device. On the upper part of the tubular structure 19 projections 20 are welded, so that there is a wide support surface for the support members 17 for the rods 13. In the projections 20 there are bores 21 distributed over the entire beam length, through which screws 25 can be passed, which engage in the clamping rails 22. With these clamping rails, the support members 17 for the rods 13 are held on the support 12.

Die Tragorgane 17 für die Stäbe 13 weisen einen Prismenkörper 14 auf, und einen Fußteil 23 mit Nasen 26, die unter die Klemmschienen 22 greifen und durch diese am Träger 12 verspannt werden. Beim Lösen der Klemmschienen 22 sind die Tragorgane 17 mit den Stäben 13 vom Träger 12 abnehmbar oder auch auf diesem seitlich verschiebbar, so daß sich auch unterschiedliche Spaltweiten oder Spreizungen zwischen den Stäben leicht einstellen lassen.The support members 17 for the rods 13 have a prism body 14 and a foot part 23 with lugs 26 which engage under the clamping rails 22 and are braced by the latter on the carrier 12. When the clamping rails 22 are loosened, the support members 17 with the rods 13 can be removed from the carrier 12 or can also be laterally displaced on the latter, so that different gap widths or spreadings between the rods can also be easily adjusted.

Fig. 3 läßt ein Tragorgan 17 für sich allein erkennen, bei dem auf ein Fußteil 23 mit Nasen 26 ein Prismenkörper 14 aufgeschweißt ist. Auf den Prismenkörper sind, wie Fig. 2 erkennen läßt, die Stäbe 13 aufgelegt. Sie können am Prismenkörper 14 angeschweißt sein und dadurch mit diesem eine Einheit bilden, es liegt aber auch im Rahmen der Erfindung, daß die Stäbe 13 auf dem Prismenkörper nur aufliegen und durch eine Klemmlasche, z. B. ein Gegenprisma 30, welches durch Schrauben angedrückt wird, auf dem Prismenkörper festgeklemmt werden. Auf diese Weise ist es möglich, bei Verschleiß nur einzelne Stäbe ohne ihr Tragorgan auszuwechseln.Fig. 3 shows a support member 17 on its own, in which a prism body 14 is welded onto a foot part 23 with lugs 26. 2, the rods 13 are placed on the prism body. You can be welded to the prism body 14 and thereby form a unit with it, but it is also within the scope of the invention that the rods 13 only rest on the prism body and by a clamping tab, for. B. a counter prism 30, which is pressed by screws, are clamped on the prism body. In this way, it is possible to replace only individual rods without their support member when worn.

Fig. 4 gibt schematische Darstellungen unterschiedlicher Stabanordnungen mit Rundstäben 13 und Dreikant- oder dreikantähnlichen Stäben 24 wieder. Die Dreikantstäbe 24 können mit ihren spitzen Seiten in einem Prismenkörper 14 liegen, die Festklemmung kann hier durch eine ebene Platte 42 erfolgen.FIG. 4 shows schematic representations of different rod arrangements with round rods 13 and triangular or triangular-like rods 24. The triangular bars 24 can lie with their pointed sides in a prism body 14, the clamping can take place here by a flat plate 42.

In den Figuren 5 bis 7 sind noch weitere Beispiele für die Befestigung der Siebstäbe an den Rohrkonstruktionen der Träger dargestellt.FIGS. 5 to 7 show further examples of the fastening of the sieve bars to the tubular structures of the supports.

Bei der aus Flachstählen zusammengeschweißten Rohrkonstruktion 32 mit den Stirnscheiben 18 der Fig. 5 weist der obere Flachstahl Auskragungen 34 auf. Auf dieser oberen Abdeckung der Rohrkonstruktion 32 liegen die insgesamt mit 17 bezeichneten Tragorgane für die Siebstäbe 13 auf, die in Prismen- oder Halbrundführungen 14 liegen. Die Tragorgane mit den Stäben sind durch Bügelschrauben 40 an der Rohrkonstruktion gehalten, wozu Bohrungen oder Schlitze in den Auskragungen vorgesehen sind.In the case of the tubular construction 32 welded together from flat steels with the end disks 18 of FIG. 5, the upper flat steel has projections 34. On this upper cover of the tubular structure 32, there are the support members for the sieve bars 13, which are denoted overall by 17 and which lie in prismatic or semicircular guides 14. The support members with the rods are held on the pipe construction by means of bow screws 40, for which purpose holes or slots are provided in the projections.

Bei dem Befestigungsbeispiel der Fig. 6 und 7 ist am oberen Teil eines Vierkantrohres 33 eine durchgehende Flacheisenschiene angeschweißt, die Auskragungen 34 gegenüber dem Rohr aufweist. Auf der Schiene mit den Auskragungen liegen die Tragorgane 38 für die Halbrundführungen 14 der Stäbe 13 auf. Die Tragorgane weisen dabei Laschen auf, in denen Bohrungen für die Durchführung von Schrauben 39 vorgesehen sind. Mit diesen Schrauben werden Klemmlaschen 36 gegen die Auskragungen 30 am Tragrohr 33 festgeklemmt. Die Tragorgane und damit die Stäbe 13 lassen sich so in beliebigen Abständen zueinander anbringen. Die Stäbe 13 werden hier, wie auch Fig. 7 erkennen läßt, in Halbrundführungen 14 gehalten, von denen die unteren am Fußteil 37 angeschweißt sind und die oberen durch Klemmplatten 42 mittels Stehbolzen 41, die in die Fußteile 37 eingeschraubt sind, festgeklemmt werden.6 and 7, a continuous flat iron rail is welded to the upper part of a square tube 33, which has projections 34 relative to the tube. The support members 38 for the semicircular guides 14 of the rods 13 rest on the rail with the projections. The support members have tabs in which holes are provided for the passage of screws 39. With these screws, clamping tabs 36 are clamped against the projections 30 on the support tube 33. The support members and thus the rods 13 can be attached to each other at any distance. The rods 13 are here, as can also be seen in FIG. 7, held in semicircular guides 14, of which the lower ones are welded to the foot part 37 and the upper ones are clamped by means of clamping plates 42 by means of stud bolts 41 which are screwed into the foot parts 37.
