Description

Die Erfindung betrifft eine Siebvorrichtung für das Abtrennen der feinkörnigen Anteile eines Siebgutes.The invention relates to a screening device for separating the fine-grained fractions of a material to be screened.

Siebvorrichtungen sind in vielfältigen Ausführungsformen bekannt und bewährt. Auch sind die Einsatzgebiete vielfältig.Sieve devices are known and proven in various embodiments. The areas of application are also diverse.

Hier ist insbesondere an die Trennung von Abfällen und Wertstoff-Fraktion aus den Bereichen Kompost, Bauschutt, Verbrennungsschlacke, Haus- und Gewerbemüll gedacht.In particular, the separation of waste and recyclable materials from the areas of compost, construction waste, incineration slag, household and commercial waste is considered.

Bei einer bekannten Siebvorrichtung für derartige Zwecke wird das Siebgut über mehrere, längs angeordnete Stangen gefördert, die eine Ebene mit einem leichten Gefälle ausbilden. Durch einen Vibrationsantrieb wird das Siebgut über die Stangen bewegt, wobei sich lange und flächige Bestandteile des Siebgutes aufrichten können und wie die feinkörnigen Anteile durch den Freiraum zwischen den Stangen durchfallen können. US1054120 offenbart eine Siebvorrichtung für das Abtrennen der feinkörnigen Anteile eines Siebgutes gemäß dem Oberbegriff des Anspruchs 1.In a known screening device for such purposes, the material to be screened is conveyed over a plurality of longitudinally arranged rods which form a plane with a slight gradient. The material to be screened is moved over the rods by a vibration drive, whereby long and flat components of the material to be screened can stand up and like the fine-grained portions can fall through the free space between the rods. US1054120 discloses a screening device for separating the fine-grained fractions of a material to be screened according to the preamble of claim 1.

Vor diesem Hintergrund macht die Erfindung es sich zur Aufgabe, eine Siebvorrichtung zur Verfügung zu stellen, bei der lange und flächenhaft sich erstreckende Anteile des Siebgutes sicher als Überkorn die Siebvorrichtung wieder verlassen.Against this background, the invention makes it an object to provide a screening device available in which long and planar portions of the Material to be screened safely leaves the screening device as oversized grain.

Gelöst wird diese technische Problematik bei einer Siebvorrichtung für das Abtrennen der feinkörnigen Anteile eines Siebgutes gemäß des Anspruchs 1 durch die Maßnahme, dass eine Vielzahl von beabstandeten Stangen quer zu einer Laufrichtung des Siebgutes angeordnet sind.This technical problem is solved in a screening device for separating the fine-grained portions of a screened item according to claim 1 by the measure that a plurality of spaced rods are arranged transversely to a running direction of the screened item.

Bevorzugt sind dabei die Stangen parallel und gleichabständig verlaufend angeordnet, womit eine wohldefinierte Körnigkeit des auszusiebenden Siebgutes vorgegeben wird.The rods are preferably arranged running parallel and equally spaced, whereby a well-defined granularity of the material to be screened is given.

Bei einer bevorzugten Ausführungsform der Siebvorrichtung nach der Erfindung ist vorgesehen, dass die Stangen auf einer Kreisbahn angeordnet eine um ihre Längsachse rotierende Trommel ausbilden.In a preferred embodiment of the screening device according to the invention it is provided that the rods are arranged on a circular path and form a drum rotating about their longitudinal axis.

Durch die Drehbewegung der Trommel fließt das Siebgut quer über die Siebstangen abwärts.The rotating movement of the drum causes the material to be screened to flow downwards across the screen bars.

In konstruktiver Ausgestaltung ist dabei vorgesehen, dass die Stangen wenigstens einseitig an einen Aufnahmering angeschlossen sind. Ein solcher Aufnahmering kann mit auf den Querschnitt der Stangen abgestimmten Durchbrechungen versehen sein, in die die Stangen eingepasst werden. Ein sicherer Halt und eine exakte Ausrichtung der Stangen wird damit gewährleistet.In a constructive embodiment it is provided that the rods are connected to a receiving ring at least on one side. Such a receiving ring can be provided with openings that are matched to the cross section of the rods and into which the rods are fitted. A secure hold and an exact alignment of the rods is guaranteed.

Sind die Stangen vergleichsweise lang, können beiderends dieser Stangen derartige Ringe vorgesehen sein, die auch für die Lagerung und den Antrieb der Trommel herangezogen werden können. Insbesondere ist dabei daran gedacht, dass ein Aufnahmering und ein Antrieb an der Einlaufseite des Siebgutes vorgesehen sind.If the rods are comparatively long, such rings can be provided at both ends of these rods, which can also be used for mounting and driving the drum. In particular, it is thought that a receiving ring and a drive are provided on the inlet side of the material to be screened.

Ein Durchsatz des Siebgutes von der Einlaufseite durch die Trommel hin zu der Auslaufseite kann in einfacher Weise durch die Maßnahme erreicht werden, dass die Längsachse der Trommel eine Neigung gegenüber einer Horizontalen aufweist. Dabei wird bevorzugt, dass der Neigungswinkel einstellbar ist, beispielsweise zwischen 0° und 5°.A throughput of the material to be screened from the inlet side through the drum to the outlet side can be achieved in a simple manner by the measure that the longitudinal axis of the drum has an inclination with respect to a horizontal. It is preferred that the angle of inclination is adjustable, for example between 0 ° and 5 °.

Bei der Erfindung ist vorgesehen, dass der Querschnitt der Stangen dreiecksförmig ist und dass Flachseiten die dem Siebgut zugewandte Siebfläche ausbilden.In the invention it is provided that the cross section of the rods is triangular and that flat sides form the screen surface facing the material to be screened.

Die Stangen mit dreiecksförmigem Querschnitt haben den Vorteil, dass der feinkörnige Anteil sicher den Spalt zwischen den Stangen durchtritt, da sich dieser Spalt aufweitet.The rods with a triangular cross-section have the advantage that the fine-grained portion safely passes through the gap between the rods, since this gap widens.

Ein weiterer Vorteil insbesondere der Anordnung und der Verwendung im Querschnitt dreiecksförmiger Stangen ist eine schnelle und einfache Abreinigung. Hierzu wird auf der siebflächenabgewandten Seite eine Walzenbürste vorgesehen. Die Länge dieser Walzenbürste entspricht wenigstens der wirksamen Länge der Stangen, über die der Siebvorgang erfolgt. Sind die Borsten der Bürste in ständigem Eingriff mit den Stangen, so wird durch die Rotation der Trommel gleichzeitig der Zwischenraum zwischen den Stangen abgereinigt.Another advantage, in particular of the arrangement and the use of rods with a triangular cross-section, is quick and easy cleaning. For this purpose, a roller brush is provided on the side facing away from the screen surface. The length of this roller brush corresponds at least to the effective length of the rods over which the screening process takes place. If the bristles of the brush are in constant contact with the rods, the space between the rods is simultaneously cleaned by the rotation of the drum.

Ist die Achse der Walzenbürste gegenüber der Längsachse der Trommel angestellt, so erfolgt eine zusätzliche Reinigungsbewegung in Längsrichtung der Stangen.If the axis of the roller brush is positioned opposite the longitudinal axis of the drum, an additional cleaning movement takes place in the longitudinal direction of the bars.

In weiterer Ausgestaltung der Siebvorrichtung nach der Erfindung ist ein Förderband, ein Trichter und/oder eine Rutsche für ein Aufbringen des Siebgutes auf die Siebfläche vorgesehen, eine erste trichterartige Auffangvorrichtung für die feinkörnigen Anteile des Siebgutes und eine zweite trichterartige Auffangvorrichtung für das Überkorn an der Auslaufseite.In a further embodiment of the screening device according to the invention, there is a conveyor belt, a funnel and / or a chute for applying the material to be screened onto the screen surface provided, a first funnel-like collecting device for the fine-grained portions of the material to be screened and a second funnel-like collecting device for the oversized grain on the outlet side.

Dabei kann daran gedacht sein, eine Trommel einerends, auf einer Einlaufseite mit dem Siebgut zu beschicken, dass das Siebgut dann die Trommel zum anderen Ende hin durchläuft und dass das Überkorn dann auf einer Austrittsseiteaustritt.It can be thought of feeding a drum with the material to be sieved at one end, on one inlet side, so that the material to be sieved then passes through the drum to the other end and that the oversized grain then exits on an outlet side.

Alternativ kann, bei entsprechenden Abmessungen der Trommel, diese einerends geschlossen sein und erfolgt die Beschickung der Trommel mit einem Siebgut von der selben Seite her, an der das Überkorn austritt. Eine einfache Lagerung und ein einfacher Antrieb über einen zentralen Bolzen an der geschlossen Seite der Trommel ist dann möglich.Alternatively, given the appropriate dimensions of the drum, it can be closed at one end and the drum is loaded with material to be sieved from the same side on which the oversized grain emerges. A simple storage and a simple drive via a central bolt on the closed side of the drum is then possible.

Die gesamte Siebvorrichtung nach der Erfindung kann in einem Rahmen angeordnet sein. Beispielhaft bei einem Gewicht von weniger als 1 t und Abmessungen von ca. 2 m x 2 m x 1,20 m ist die Siebvorrichtung nach der Erfindung auch für einen mobilen Einsatz bestens geeignet. Jedoch können Gewicht und Abmessungen nach vorgegebenem Lastenheft erheblich größer sein.The entire screening device according to the invention can be arranged in a frame. For example, with a weight of less than 1 t and dimensions of approx. 2 m x 2 m x 1.20 m, the screening device according to the invention is also ideally suited for mobile use. However, the weight and dimensions can be considerably larger according to the specified specification.

Die anhand der Zeichnung näher erläuterte Siebvorrichtung 1 nach der Erfindung ist in einem stabilen Rahmen 2 angeordnet und mit Abmessungen von ca. 2 m x 2 m x 1,20 m und einem Gewicht von unter 1 t auch für den mobilen Einsatz bestens geeignet.The sieving device 1 according to the invention, explained in more detail with reference to the drawing, is arranged in a stable frame 2 and, with dimensions of approximately 2 m × 2 m × 1.20 m and a weight of less than 1 t, is also ideally suited for mobile use.

Bei dem Ausführungsbeispiel wird durch eine Vielzahl von beabstandeten Stangen 3, angeordnet auf einer Kreisbahn, eine um ihre Längsachse 4 rotierende Trommel 5 ausgebildet. Dabei verlaufen die Stangen 3 parallel und sind gleich abständig verlaufend. Auf der Einlaufseite 6 eines nicht dargestellten Siebgutes ist ein Aufnahmering 7 für die Stangen 3 sowie ein Elektromotor als Antrieb 8 vorgesehen.In the exemplary embodiment, a drum 5 rotating about its longitudinal axis 4 is formed by a multiplicity of spaced rods 3, arranged on a circular path. The rods 3 run parallel and are equally spaced. A receiving ring 7 for the rods 3 and an electric motor as a drive 8 are provided on the inlet side 6 of a material to be screened (not shown).

Ein Beschicken der Trommel 5 mit einem Siebgut erfolgt über ein Förderband 9.The drum 5 is loaded with material to be screened via a conveyor belt 9.

Durch die Drehbewegung der Trommel 5 um die Achse 4 wird eingebrachtes Siebgut angehoben und fließt darauffolgend quer über die Stangen 3 nach unten.As a result of the rotary movement of the drum 5 around the axis 4, the material to be screened is lifted and then flows downwards across the rods 3.

Der Durchsatz durch die Trommel 5 wird durch die Maßnahme erreicht, dass die Längsachse 4 der Trommel 5 gegenüber der Horizontalen angestellt ist. Bevorzugt ist der Neigungswinkel zwischen 0° und ca. 5° einstellbar. Hierzu ist die Trommel 5 mit Antrieb 8 innerhalb des Rahmens 2 in einem gegenüber diesem verschwenkbaren weiteren Rahmen 10 gehalten.The throughput through the drum 5 is achieved by the fact that the longitudinal axis 4 of the drum 5 is positioned relative to the horizontal. The angle of inclination is preferably adjustable between 0 ° and approx. 5 °. For this purpose, the drum 5 with drive 8 is held within the frame 2 in a further frame 10 which can be pivoted with respect to this.

Unterhalb der Trommel 5 ist eine erste trichterartige Auffangvorrichtung 11 für ein Auffangen des ausgesiebten feinkörnigen Anteils des Siebgutes vorgesehen. Auf der Austrittsseite 12 ist eine zweite trichterartige Auffangvorrichtung 13 für das austretende Überkorn vorgesehen. Die Höhe der beiden Auffangvorrichtungen 11,13 reicht bis etwa zur Mitte der Trommel 5.Below the drum 5, a first funnel-like collecting device 11 is provided for collecting the fine-grained portion of the screened material which has been screened out. On the outlet side 12 there is a second funnel-like collecting device 13 for the oversized grain that emerges intended. The height of the two collecting devices 11, 13 extends approximately to the middle of the drum 5.

Die Stangen 3 von dreieckförmigem Querschnitt sind in Durchbrechungen des Aufnahmerings 7 gefasst und bilden mit einer Flachseite die trommelinnere Siebfläche aus. Damit ist eine Spitze einer Stange 3 radial auswärts gerichtet. Damit fällt zum einen in einen Spalt zwischen zwei Stangen 3 eingetretenes, feinkörniges Siebgut sicher durch die Spalte und erlaubt dieser Querschnitt eine effektive Reinigung der Stangen mit einer Walzenbürste 15. Die Länge der Walzenbürste 15 entspricht der wirksamen Länge der Stangen 3, über die der Siebvorgang stattfindet. Dabei ist die Walzenbürste 15 in ständigem Einsatz in den Zwischenräumen zwischen den Stangen 3. Der Reinigungseffekt kann weiter erhöht werden, wenn die Achse der Walzenbürste 15 gegenüber der Längsachse 4 der Trommel 5 angestellt ist.The rods 3 of triangular cross-section are held in openings in the receiving ring 7 and, with one flat side, form the sieve surface on the inside of the drum. So that a tip of a rod 3 is directed radially outward. Thus, on the one hand, fine-grained screenings that have entered a gap between two rods 3 fall safely through the gap and this cross section allows effective cleaning of the rods with a roller brush 15. The length of the roller brush 15 corresponds to the effective length of the rods 3 over which the screening process takes place. The roller brush 15 is in constant use in the spaces between the rods 3. The cleaning effect can be further increased if the axis of the roller brush 15 is positioned relative to the longitudinal axis 4 of the drum 5.
