Description

Die vorliegende Erfindung bezieht sich auf eine Siebmaschine gemäß Oberbegriff des Anspruchs 1.The present invention relates to a screening machine according to the preamble of claim 1.

Siebmaschinen mit einer beweglichen, durch Siebmatten aufgebaute Siebfläche sind beispielsweise aus der AT 379.088 bekannt. Die Bewegung der Siebmatten erfolgt in der Regel durch ein amplitudenerregtes Schwingsystem, welches an einem bewegten Siebkasten gelagert ist. Die die Siebfläche bildenden Siebmatten werden dabei abwechselnd am Siebkasten und am Schwingsystem befestigt, sodass durch die Relativbewegung der beiden Systeme zueinander, eine Stauchung bzw. Dehnung der Siebmatten bewirkt wird.Screening machines with a mobile, by screen mats constructed sieve surface are for example from the AT 379.088 known. The movement of the screen mats is usually done by an amplitude-excited oscillating system which is connected to a is moved moving sieve box. The forming the screen surface Sieve mats are alternately on the sieve box and on Attached vibration system, so that by the relative movement of the Both systems to each other, a compression or elongation of the Sieve mats is effected.

Um z.B. mehrere Fraktionen zu erhalten ist es auch bekannt zwei, solche amplitudenerregten Schwingsysteme unabhängig voneinander an einem schwingenden Siebkasten anzuordnen.For example, It is also known to get several fractions two, such amplitude-excited oscillatory systems independently to arrange each other on a vibrating screen box.

Dies hat jedoch zum Nachteil, dass eine solche Zweidecksiebmaschine sehr hoch baut und daher nicht überall einsetzbar ist. Weiters ist der konstruktive Aufwand für zwei Schwingsysteme relativ hoch und eine Abstimmung muss für jedes Schwingsystem einzeln erfolgen. An den Bau mehrdeckiger (>2) Schwingsysteme ist aufgrund dieser Ausführungen nicht zu denken.However, this has the disadvantage that such Zweidecksiebmaschine very high builds and therefore not everywhere can be used. Furthermore, the design effort for two Oscillation systems are relatively high and a vote must be for each Singling system done individually. To the construction of multi-deck (> 2) Oscillation systems is not due to these statements think.

Es ist daher die Aufgabe der vorliegenden Erfindung eine Siebmaschine zu schaffen, die diese Nachteile vermeidet, klein baut und trotzdem die Vorteile der selektiveren Fraktionierung einer Zweidecksiebmaschine aufweist.It is therefore the object of the present invention To create a screening machine that avoids these disadvantages, small and still take advantage of more selective fractionation a Zweidecksiebmaschine has.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.This is achieved by the characterizing features according to the invention of claim 1 achieved.

Dadurch ist es lediglich erforderlich ein einziges Schwingsystem am Siebkasten anzuordnen, in welchem die Siebmatten, neben der Fixierung am Siebkasten, fixiert sind. As a result, it is only required a single Arrange oscillating system on the screen box, in which the Sieve mats, next to the fixation on the sieve box, are fixed.

Die gesamte Siebmaschine baut dadurch wesentlich niedriger obwohl mehrere, durch Siebmatten gebildete Siebflächen zur Verfügung stehen. Ein Einsatz als mobile Siebanlage ist somit ebenfalls möglich. Die Ausbildung von zwei oder mehreren Siebflächen kann problemlos verwirklicht werden.The entire screening machine builds considerably lower Although several, formed by screen mats screening surfaces for To be available. A use as a mobile sieve is thus also possible. The training of two or more Screen surfaces can be realized easily.

Die kennzeichnenden Merkmale des Anspruchs 2 ermöglichen eine Weiterbeförderung des Siebgutes in Neigungsrichtung.The characterizing features of claim 2 enable a Further transport of the screenings in the direction of inclination.

Die kennzeichnenden Merkmale der Ansprüche 3 bis 5 beschreiben eine bevorzugte Ausführungsvariante der Befestigung der Schwingrahmenquerträger am Schwingsystem. Dadurch ist es möglich, mehrere Siebflächen an ein und demselben Schwingsystem vorzusehen.The characterizing features of claims 3 to 5 describe a preferred embodiment of the attachment of the Oscillating frame cross member on the oscillating system. That's it possible, several screen surfaces on one and the same Provide oscillating system.

Die unterschiedliche geometrische Anordnung der Fixierungspunkte der Siebrahmenquerträger an den Befestigungsbauteilen gemäß Ansprüchen 6 und 7 erfolgt anhand von Erfahrungswerten in Bezug auf das jeweilige Siebgut und bewirkt eine Erhöhung der Siebwirkung.The different geometric arrangement of Fixation points of the Siebrahmenquerträger to the Fastening components according to claims 6 and 7 is based on of experience in relation to the respective screenings and causes an increase in the screening effect.

Das kennzeichnende Merkmale der Ansprüche 8 und 9 beschreiben eine bevorzugte Anordnungsgmöglichkeit der Siebflächen, welche in der Praxis die beste Siebwirkung erzielt.The characterizing features of claims 8 and 9 describe a preferred arrangement possibility of the screen surfaces, which achieved the best screening effect in practice.

Wie aus Fig.1 ersichtlich besteht eine erfindungsgemäße Zweioder Mehrdecksiebmaschine aus einem Siebwangen aufweisenden Siebkasten 1 der auf Federn 4 gegenüber einem fixen Untergrund 2 abgestützt wird und einem den Siebkasten 1 in Schwingungen versetzenden Antrieb 3. Dieser ist im vorliegenden Fall als Doppelunwuchtantrieb mit gegenläufigen Unwuchtgewichten ausgebildet, wodurch eine lineare Erregerschwingung erzeugt wird. Prinzipiell sind jedoch alle Arten von Unwuchtantrieben einsetzbar. Fig.2 zeigt beispielsweise den Einsatz eines einfachen Unwuchtantriebs 3, welche den Siebkasten in kreisförmige Schwingungen versetzt.As can be seen from Fig.1 there is a Zweioder invention Mehrdecksiebmaschine from a Siebwangen having Sieve box 1 of the springs 4 against a fixed surface 2 is supported and the screen box 1 into vibration staggering drive 3. This is in the present case as Double unbalance drive with opposing imbalance weights formed, whereby a linear excitation oscillation generated becomes. In principle, however, all types of unbalance drives used. Fig.2 shows, for example, the use of a simple unbalance drive 3, which the sieve box in offset circular oscillations.

Am Siebkasten 1 ist ein einen Schwingrahmen bildendes Schwingsystem angeordnet, welches aus an den Siebwangen des Siebkastens 1 über vorzugsweise elastische Gummiblöcke 8 gelagerten Schubstangen 5 sowie an diesen angeordneten Befestigungsbauteilen 6 besteht. Die Befestigungsbauteile 6 erstrecken sich im wesentlichen rechtwinkelig zur Längsachse der Schubstangen 5 sowie parallel zu den Siebwangen des Siebkastens 1. An den Befestigungsbauteilen 6 sind zwei Schwingrahmenquerträger 7 im wesentlichen untereinander fixiert. Die Schwingrahmenquerträger verbinden einander gegenüberliegende Befestigungsbauteile 6 miteinander.At the screen box 1 is a forming a swing frame Oscillating system arranged, which from on the Siebwangen of Sieve box 1 on preferably elastic rubber blocks. 8 mounted push rods 5 and arranged on these Fixing components 6 consists. The fastening components 6 extend substantially perpendicular to the longitudinal axis the push rods 5 and parallel to the wire cheeks of the Sieve box 1. At the fastening components 6 are two Oscillating frame cross member 7 substantially with each other fixed. The swing frame cross beams connect each other opposite fastening components 6 with each other.

Die Siebwangen des Siebkastens 1 sind über Siebkastenquerträger 12 miteinander verbunden.
Die Siebflächen 9,10 werden durch einzelne Siebmatten 11 aufgebaut. Jede Siebmatte 11 ist abwechselnd an einem Schwingrahmenquerträger 7 und einem Siebkastenquerträger 12 befestigt.The screen cheeks of the screen box 1 are connected to each other via screen box cross member 12.
The sieve surfaces 9, 10 are constructed by individual sieve mats 11. Each screen mat 11 is alternately attached to a swing frame cross member 7 and a Siebkastenquerträger 12.

Die Befestigung der Schwingrahmenquerträger 7 und Siebkastenquerträger 12 einer Siebfläche 9,10 erfolgt im wesentlichen entlang einer geraden, so dass sich eine durchgehende im wesentlichen gerade Siebfläche 9,10 ergibt. Abweichungen von einer geraden Siebfläche 9,10 ergeben sich systembedingt aufgrund eines gewissen Durchhangs der einzelnen Siebmatten. Dies ist erforderlich um das Stauchen- und Dehnen der Siebmatten 11 zu ermöglichen.The attachment of the swing frame cross member 7 and Siebkastenquerträger 12 a sieve surface 9,10 takes place in Substantially along a straight, so that one continuous substantially straight screen surface 9,10 results. Deviations from a straight screen surface 9,10 arise systemic due to a certain sag of the individual Screen mats. This is required for upsetting and stretching to enable the screen mats 11.

Die Funktionsweise der Siebvorrichtung ist wie folgt: der Schwingrahmen wird durch den mittels Unwuchtantrieb 3 in Schwingungen versetzten Siebkasten 1 amplitudenerregt ebenfalls in Schwingungen versetzt. Durch die elastische Lagerung der Schubstangen 5 des Schwingrahmens am Siebkasten 1 entseht eine zur Grundschwingung des Siebkastens 1 versetzte Schwingung des Schwingrahmens. Durch die abwechselnde Befestigung der Siebmatten 11 am Siebkasten 1 bzw. am Schwingrahmen (Befestigungsbauteile 6) werden die Siebmatten 11 abwechselnd gestaucht und gedehnt. Dies wiederum bewirkt eine optimale Siebwirkung.The operation of the screening device is as follows: the Oscillating frame is the by means of unbalance drive 3 in Vibrations offset sieve box 1 amplitude-excited also vibrated. By the elastic Storage of the push rods 5 of the swing frame on the screen box. 1 entseht one staggered to the fundamental vibration of the sieve box 1 Vibration of the swing frame. By the alternate Fixing the screen mats 11 on the screen box 1 or am Oscillating frame (fastening components 6) are the screen mats 11 alternately compressed and stretched. This in turn causes an optimal screening effect.

Die erfindungsgemäße Siebvorrichtung zeichnet sich insbesondere dadurch aus, dass sie zwei- bzw. mehrdeckig ist und trotzdem lediglich ein Schwingsystem vorhanden ist. Dadurch ergibt sich der Vorteil, dass die gesamte Vorrichtung sehr niedrig baut, wodurch auch mobile Einsätze möglich sind. Weiters ist die Abstimmung der Schwingsysteme wesentlich einfacher, da lediglich ein System abgestimmt werden muss. Bei einer mehrdeckigen Ausführungsvariante sind entsprechend mehrere Schwingrahmenquerträger 7 an den jeweiligen Befestigungsbauteilen 6 angeordnet.The screening device according to the invention is characterized in particular the fact that it is two- or multi-deck and still only a vibration system is present. This results in the advantage that the entire device very low build, which also mobile applications are possible. Furthermore, the tuning of the vibration systems is essential easier, because only one system has to be tuned. at a multi-deck variant are accordingly several swing frame cross member 7 to the respective Fastening components 6 arranged.

Aus Übersichtlichkeitsgründen sind im vorliegenden Ausführungsbeispiel lediglich zwei Siebdecks = Siebflächen 9, 10 verwirklicht. Es liegt jedoch nahe, beliebig viele Siebflächen übereinander angeordnet vorzusehen.For clarity, are in the present Embodiment only two screen decks = screen surfaces 9, 10 realized. However, it is obvious, as many as you like Provide screen surfaces arranged one above the other.

Zur weiteren Erhöhung der Siebleistung ist vorgesehen, die Fixierung der einzelnen an einem Befestigungsbauteil 6 angeordneten Schwingsystemquerträger 7 in mindestens zwei normal zur Längsachse der Schubstangen 5 verlaufenden Ebenen 14, 15 vorzunehmen. Dabei entsteht ein Versatz "a", der sich nach dem der Siebmaschine zugeführten Aufgabematerial und den Trennschnittgrößen richtet.To further increase the screening performance is provided, the Fixation of the individual to a fastening component. 6 arranged oscillating system cross member 7 in at least two normal to the longitudinal axis of the push rods 5 extending levels 14, 15 make. This results in an offset "a", which is after the screening machine supplied feed material and the Divisional section sizes.

Es ist jedoch auch möglich, die Fixierung der einzelnen an einem Befestigungsbauteil 6 angeordneten Schwingsystemquerträger 7 in einer einzigen normal zur Längsachse der Schubstangen (5) verlaufenden Ebene (13) vorzunehmen.However, it is also possible to fix the individual arranged a fastening component 6 Oscillating system cross member 7 in a single normal to Longitudinal axis of the push rods (5) extending plane (13) make.

Auch die Siebkastenquerträger 12 der einzelnen Siebflächen 9, 10 können entweder jeweils in einer Ebene normal zur Längsachse der Schubstangen 5 angeordnet werden, oder aber mit einem Versatz "a" (siehe Fig.2).Also the Siebkastenquerträger 12 of the individual screen surfaces 9, 10 can either be in a plane normal to Longitudinal axis of the push rods 5 are arranged, or with an offset "a" (see Fig.2).

Das vorliegende Schwingsystem kann auch in Bananenausführung mit kontinuierlich abnehmender Siebdeckneigung ausgeführt werden.The present oscillating system can also be used in banana style with continuously decreasing screen deck inclination become.
