Description

Die Erfindung betrifft ein Rotationssiebelement sowie ein Verfahren zum Reinigen von Rotationssiebelementen.The invention relates to a rotary screen element as well a method for cleaning rotary screen elements.

Gemäß dem Stand der Technik (G 93 07 096.9) sind Siebsysteme bekannt, welche bei Vorsortierung von Schüttgütern, wie Kompost, Rindenhumus beziehungsweise -mulch, Torf und so weiter, aber auch beim Bauschutt-Recycling Anwendung finden.According to the state of the art (G 93 07 096.9) are screening systems known which for pre-sorting bulk goods, such as compost, bark humus or mulch, peat and so on, but also in building rubble recycling application Find.

Diese zum Stand der Technik gehörenden Siebsysteme sind derart aufgebaut, dass parallele synchron angetriebene Wellen drehfest und zueinander auf Lücke axial versetzt gehalterte Gruppen von Siebsternen aus Gummiformteilen mit elastisch nachgiebigen Fingern aufweisen. Die Finger sind in Umlaufrichtung nacheilend ausgerichtet und als sichelförmige Abstreifzinken ausgebildet. Die jeweiligen Abstände zwischen benachbarten Siebsternen und Siebsternwalzen werden dem zu sortierenden Gut angepasst.These screening systems belonging to the state of the art are constructed in such a way that parallel synchronous drives Shafts rotatably and axially offset from each other to gap Groups of sieve stars made of molded rubber parts with have resilient fingers. The fingers are lagging in the circumferential direction and as a sickle-shaped Scraper tines formed. The respective distances between adjacent screen stars and screen star rollers adapted to the goods to be sorted.

Damit die Siebergebnisse eine gleichbleibende Qualität haben und Siebelemente nicht vorzeitig verschleißen oder die Anlage durch fadenähnliche Gegenstände oder feuchte oder klebrige Anhaftungen verschmutzt und zum Stillstand der Anlage führt, müssen die Siebelemente und ihre Zwischenräume gereinigt werden.So that the sieving results have a constant quality and do not wear screen elements prematurely or the system due to thread-like objects or damp or sticky contaminants soiled and come to a standstill of the system, the sieve elements and their spaces getting cleaned.

Anhaftendes Material muss mit aufwendigen und produktionseinschränkenden Vorrichtungen entfernt werden. Diese Vorrichtungen sind aufwendig, teuer und längerfristig nicht zur effektiven und wirkungsvollen Reinigung einsetzbar. Darüber hinaus muss bei diesen zum Stand der Technik gehörenden Vorrichtungen der Siebvorgang für den Reinigungsvorgang unterbrochen werden, was ebenfalls von Nachteil ist.Adhesive material must be elaborate and restrict production Devices are removed. This Devices are complex, expensive and not in the long term can be used for effective and effective cleaning. In addition, these must be part of the state of the art Devices of the screening process for the cleaning process be interrupted, which is also a disadvantage.

Das der Erfindung zugrunde liegende technische Problem besteht darin, ein Rotationssiebelement sowie ein Verfahren zum Reinigen von Rotationssiebelementen und deren Zwischenräumen anzugeben, mit dem eine kontinuierliche Reinigung möglich ist, wobei der Reinigungsvorgang während des Siebvorganges stattfindet und welches darüber hinaus einfach und preisgünstig ist.The technical problem underlying the invention consists of a rotary screen element and a method for cleaning rotary screen elements and their gaps specify with which a continuous cleaning is possible, the cleaning process during the screening process takes place and which is also easy and is inexpensive.

Dadurch, dass das Rotationssiebelement, welches als Siebstern ausgebildet ist, in oder an wenigstens einem Finger ein Verstärkungsteil aufweist, fährt der Finger mit diesem Verstärkungsteil oder das Verstärkungsteil während des Siebvorganges ständig über den Bund benachbarter Rotationssiebelemente. Hierdurch können sich auf dem Bund kein Schmutz oder Fremdkörper ansammeln, so dass eine ständige Reinigung während des eigentlichen Siebvorganges stattfindet.The fact that the rotary screen element, which as Siebstern is formed in or on at least one finger has a reinforcement part, the finger moves along this reinforcement part or the reinforcement part during the sieving process constantly over the bundle of adjacent rotary sieve elements. As a result, no can on the federal government Accumulate dirt or debris so that a constant Cleaning takes place during the actual sieving process.

Das erfindungsgemäße Verstärkungsteil weist eine größere radiale Ausdehnung als axiale Ausdehnung auf. Es ist vorteilhaft im Wesentlichen der sichelförmigen Form des wenigstens einen Fingers angepasst ausbildet.The reinforcing part according to the invention has a larger one radial expansion as axial expansion. It is advantageously essentially the crescent shape of the at least trained a finger.

Dadurch, dass die radiale Ausdehnung des Verstärkungsteiles wenigstens so groß wie die radiale Ausdehnung des Fingers ist, das heißt, dass das Verstärkungsteil entweder annähernd bündig mit dem Finger abschließt oder über den Finger übersteht, fährt das Verstärkungsteil bei jeder Umdrehung über den Bund des benachbarten Rotationssiebelementes. Because of the radial expansion of the reinforcing part at least as large as the radial extent of the Fingers is, that is, the reinforcement part either almost flush with the finger or over the If the finger protrudes, the reinforcement member moves with every revolution over the collar of the adjacent rotary screen element.

Erfindungsgemäß weist das Verstärkungsteil eine größere Steifigkeit als der Finger des Rotationssiebelementes auf.According to the invention, the reinforcing part has a larger one Stiffness as the finger of the rotary screen element on.

Die Rotationssiebelemente bestehen üblicherweise aus Gummi oder einem elastischen Kunststoff.The rotary screen elements usually consist of Rubber or an elastic plastic.

Vorteilhaft ist das Verstärkungsteil aus Stahl, insbesondere verschleißfreiem Stahl, Kunststoff und/oder einem keramischen Werkstoff hergestellt.The reinforcing part made of steel is particularly advantageous wear-free steel, plastic and / or one made of ceramic material.

Das Verstärkungsteil ist vorteilhaft auf der Seite des Fingers angeordnet, welche in Vorlaufrichtung liegt.The reinforcing part is advantageous on the side of the Fingers arranged, which is in the forward direction.

Zur Befestigung des Verstärkungsteiles weist der Finger wenigstens eine Bohrung auf. Das Verstärkungsteil weist ebenfalls wenigstens eine Bohrung auf, wobei die Bohrungen derart angeordnet sind, dass die Bohrungen übereinanderliegen, wenn das Verstärkungsteil fertig montiert ist. Durch jeweils eine Bohrung des Fingers und des Verstärkungsteiles wird ein Befestigungselement gesteckt und befestigt. Wird ein Niet verwendet, wird diese entsprechend aufgeweitet. Es ist auch möglich, Bolzen oder dergleichen zu verwenden.The finger points to the attachment of the reinforcement part at least one hole. The reinforcing part points also at least one hole, the holes are arranged in such a way that the bores lie one above the other, when the reinforcement part is fully assembled. By one hole each in the finger and the reinforcement part a fastening element is inserted and fastened. Becomes If a rivet is used, it is expanded accordingly. It it is also possible to use bolts or the like.

Üblicherweise ist es ausreichend, in dem Finger und in dem Verstärkungselement jeweils eine Bohrung vorzusehen, durch die das Befestigungselement greift.Usually it is sufficient to put in and in the finger to provide a hole for the reinforcing element, through which the fastener engages.

Die Bohrung ist, um die Stabilität zu erhöhen, vorteilhaft in der äußeren Hälfte oder im äußeren Drittel des Fingers angeordnet.The hole is advantageous to increase stability in the outer half or in the outer third of the Fingers arranged.

Das Verstärkungsteil weist an dem Ende, welches in Richtung der Nabe des Rotationssiebelementes angeordnet wird, wenigstens einen Vorsprung auf, der in einer Ausnehmung einer dem Finger benachbarten Kehle angeordnet ist.The reinforcing part has at the end which in Direction of the hub of the rotary screen element arranged is, at least one protrusion in a recess a throat adjacent to the finger is arranged.

Da das Verstärkungsteil vorteilhaft auf der Seite des Fingers angeordnet ist, welche in Vorlaufrichtung des Fingers liegt, kann der Finger mit dem darauf angeordneten Verstärkungsteil beim Siebvorgang ausweichen, sofern dies notwendig sein sollte. Der Finger ist nach wie vor nachgiebig ausgestaltet, weist jedoch eine wesentlich höhere Steifigkeit als die übrigen Finger auf.Since the reinforcement part is advantageously on the side of the Finger is arranged, which is in the forward direction of the finger lies, the finger with the arranged on it If necessary, avoid the reinforcement part during the sieving process should be necessary. The finger is still compliant designed, but has a much higher Stiffness than the rest of the fingers.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Kehle, die dem Finger mit dem Verstärkungsteil in Nachlaufrichtung benachbart angeordnet ist, in einem größeren Grad geschlossen als die restlichen Kehlen, damit der Finger insgesamt noch stabiler wird. Dies hat den Vorteil, dass das Verstärkungsteil mit seinem Vorsprung nicht aus der Ausnehmung herausrutschen kann, sollte sich der Finger einmal sehr stark verbiegen.According to a preferred embodiment of the invention is the throat that the finger with the reinforcement part in Trailing direction is arranged adjacent, in a larger Degrees closed than the remaining throats so the Finger becomes even more stable overall. This has the advantage that the reinforcing part with its projection is not enough the recess can slide out, the finger should bend once very strongly.

Gemäß einer weiteren Ausführungsform der Erfindung ist das Verstärkungsteil in einem Finger angeordnet. Das Verstärkungsteil ist hierbei wenigstens teilweise von dem Material des Fingers umschlossen.According to a further embodiment of the invention the reinforcement part arranged in a finger. The reinforcement part is at least partially from the material of the finger.

In diesem Fall wird das Verstärkungsteil nicht nach der Herstellung des Rotationssiebelementes an diesem angebracht, sondern während des Herstellungsvorganges des Rotationssiebelementes gleich in dieses mit eingearbeitet.In this case, the reinforcement part is not after attached to the manufacture of the rotary screen element, but during the manufacturing process of the rotary screen element immediately incorporated into this.

Insbesondere bei der Ausführungsform, bei dem das Verstärkungsteil in dem Finger angeordnet ist, ist es vorteilhaft, wenn das Verstärkungsteil Durchbrüche aufweist. In diesem Fall wird eine bessere Verbindung mit dem elastischen Rotationssiebelement erzielt.In particular in the embodiment in which the reinforcing part is arranged in the finger, it is advantageous if the reinforcement has openings. In this case will have a better connection with the elastic Rotating sieve element achieved.

Wird das Verstärkungsteil in einem Finger des Rotationssiebelementes angeordnet, ist das Verstärkungsteil vorteilhaft mit einem hakenförmig oder ösenförmig ausgebildeten Ende versehen, welches im Nabenbereich des Rotationssiebelementes angeordnet ist.If the reinforcing part is in a finger of the rotary screen element arranged, the reinforcing part is advantageous with a hook-shaped or eyelet-shaped Provide end, which in the hub area of the rotary screen element is arranged.

Gemäß der Erfindung ist es ausreichend, bei jedem Rotationssiebelement eines Siebsystems ein Verstärkungsteil vorzusehen. Es ist jedoch auch möglich, an oder in mehreren Fingern ein Verstärkungsteil anzuordnen.According to the invention, it is sufficient for each rotary screen element a reinforcement part of a screening system to provide. However, it is also possible to have one or more Fingers to arrange a reinforcement.

Dadurch, dass benachbarte Rotationssiebelemente mit unterschiedlichen Umlaufgeschwindigkeiten angetrieben werden, wird kontinuierlich der Bund eines benachbarten Rotationssiebelementes mit Hilfe des Verstärkungsteiles gereinigt. Wird ein Rotationssiebelement beispielsweise mit 15 Umdrehungen pro Minute und das benachbarte Rotationssiebelement beispielsweise mit 17 Umdrehungen pro Minute angetrieben, benötigt die Vorrichtung 255 Umdrehungen, bis der Bund einmal komplett gereinigt ist.The fact that adjacent rotary screen elements with different speeds are driven, continuously the collar of an adjacent rotary screen element cleaned with the help of the reinforcement part. If, for example, a rotary screen element is 15 Revolutions per minute and the adjacent rotary screen element for example driven at 17 revolutions per minute, the device requires 255 revolutions for the Bund once is completely cleaned.

Durch diesen kontinuierlichen Reinigungsvorgang wird schon im Ansatz vermieden, dass sich Schmutzpartikel, insbesondere bei feuchten Siebgütern, auf dem Bund festsetzen. Es wird auch verhindert, dass sich fadenförmige Verunreinigungen, wie Seile, Netze oder dergleichen, auf dem Bund festsetzen und den Siebvorgang behindern.Through this continuous cleaning process Even in the beginning avoided that dirt particles, in particular if the screenings are moist, fix them on the bundle. It also prevents filamentous contaminants, such as ropes, nets or the like, on the waistband fix and hinder the sieving process.

Die erfindungsgemäße Vorrichtung hat den Vorteil, dass eine kontinuierliche Reinigung möglich ist. Der eigentliche Siebprozess muss für eine Reinigung nicht unterbrochen werden.The device according to the invention has the advantage that continuous cleaning is possible. The actual The screening process does not have to be interrupted for cleaning.

Werden die Verstärkungsteile auf den Fingern angeordnet, hat dies den Vorteil, dass zum einen zum Stand der Technik gehörende Siebvorrichtungen nachgerüstet werden können. Zum anderen ist es möglich, bei Verschleiß eines oder mehrerer Verstärkungsteile diese einzeln auszuwechseln, ohne das gesamte Rotationssiebelement auswechseln zu müssen.If the reinforcement parts are arranged on the fingers, This has the advantage that, on the one hand, the state of the Screening devices belonging to technology can be retrofitted can. On the other hand, it is possible to wear one or replace several reinforcement parts individually, without having to replace the entire rotary screen element have to.

Weitere Einzelheiten der Erfindung können den Unteransprüchen entnommen werden.Further details of the invention can be found in the subclaims be removed.
