Description

Die Erfindung bezieht sich auf eine Schubzentrifuge nach dem Oberbegriff des Hauptanspruchs.The invention relates to a pusher centrifuge according to the Preamble of the main claim.

Eine Schubzentrifuge ist beispielsweise aus dem DE 89 08 470 U1 bekannt und dient zur Fest- und Flüssigtrennung von Materialien. Die bekannte Zentrifuge besteht aus einem ortsfest gelagerten Maschinenrahmen, einen mit diesem verbundenen Eingabetrichter und Festmaterialauslauf, sowie einem Flüssigauslauf und einem zylindrischen Aufnahmegehäuse für eine Aufnahmetrommel und einer flüssigkeitsdichten Zylinderwanne. In dieser Wanne ist die rotierend angetriebene, mit heb- und senkbarem Schubboden ausgestattete Aufnahmetrommel angeordnet.A push centrifuge is for example from DE 89 08 470 U1 known and used for the solid and liquid separation of materials. The known centrifuge consists of a stationary Machine frame, an input funnel connected to it and Solid material outlet, as well as a liquid outlet and one cylindrical housing for a drum and a liquid-tight cylinder pan. It is rotating in this tub driven, equipped with lifting and lowering moving floor Recording drum arranged.

Der Vorteil einer solchen Schubbodenzentrifuge ist eine bessere Feststoff- und Flüssigstofftrennung und ein kontinuierlicher Durchfluß des Materials.The advantage of such a moving floor centrifuge is a better one Solid and liquid separation and a continuous flow of the material.

Neben diesem Vorteil können solche Zentrifugen auch Nachteile aufweisen. Beim Zentrifugieren kann es vorkommen, daß lange Materialien, wie zum Beispiel Stangen, Lappen, Vliese in die Zentrifuge gelangen. Der Schubboden der Zentrifuge ist mit den Materialführungsflächen durch Stege verbunden, An diesen Stegen können unter Umständen diese Materialien verkanten oder hängenbleiben. In diesem Fall kommt es in der Zentrifuge zu Verstopfungen, dadurch zu Störungen und Stillstand.In addition to this advantage, such centrifuges can also have disadvantages exhibit. When centrifuging, it can happen that long Materials such as rods, rags, fleeces in the Centrifuge. The push floor of the centrifuge is with the Material guide surfaces connected by webs, on these webs can possibly tilt these materials or get stuck. In this case it happens in the centrifuge Blockages, resulting in malfunctions and standstill.

Diese Aufgabe wird, ausgehend von dem Oberbegriff des Hauptanspruchs durch desssen kennzeichnenden Merkmale gelöst.This task is based on the generic term of Main claim solved by its characteristic features.

Eine erfindungsgemäße Zentrifuge, deren Schubboden und Materialführungsfläche voneinander getrennt eine Heb- und Senkbewegung bzw. eine Auf- und Abbewegung ausführen und getrennt voneinander angetrieben werden, weist verschiedene Vorteile auf. Werden Materialien wie Stangen, Lappen, Vliese zentrifugiert, verursachen diese Materialien keine Verstopfungen, Störungen und Stillstand der Zentrifuge. A centrifuge according to the invention, its moving floor and Material lifting surface separated from each other a lifting and Execute lowering movement or an up and down movement and driven separately from each other has several advantages on. If materials such as rods, rags, fleeces are centrifuged, these materials do not cause constipation, interference and The centrifuge stops.

Da keine Verbindungsstege zwischen Schubboden und Materialführungsfläche erforderlich sind, ist der Durchtritt für das zu zentrifugierende Material nicht unterbrochen. Damit können sich keine Teile an irgendwelchen Stegen anlagern.Since there are no connecting webs between the moving floor and Material guide area is required, the passage for that is too centrifuging material not interrupted. No one can deal with it Store parts on any webs.

Die Zentrifuge arbeitet vollautomatisch, die manuelle Entleerung entfällt. Es werden hohe Personalkosten gespart. Die Lebensdauer der Zentrifuge wird erheblich verlängert. Die Abnutzung und Beschädigung wird reduziert. Es werden Reparaturenkosten und Materialkosten gespart.The centrifuge works fully automatically, the manual emptying not applicable. High personnel costs are saved. The lifespan of the Centrifuge is extended considerably. Wear and damage is reduced. There will be repair costs and material costs saved.

In einer Ausgestaltung der Zentrifuge ist zur Absaugung von Restmaterial ein Saugrüssel vorgesehen. Dieser erstreckt sich in die Aufnahmetrommel und ist in einer vorteilhaften Ausgestaltung längs verschiebbar angeordnet. Diese Längsverschiebung kann über einen Stellantrieb erfolgen. Die Absaugung weist ein Gebläse auf, sowie eine Feststoffgastrennung.In one configuration, the centrifuge is used for the extraction of Residual material provided a proboscis. This extends into the Recording drum and is longitudinal in an advantageous embodiment slidably arranged. This longitudinal displacement can over a Actuator. The suction has a fan and a Solid gas separation.

Gemäß einer vorteilhaften Ausgestaltung ist an der Materialführungsfläche ein Verteiler angeordnet. Dieser Verteiler hat die Aufgabe, den zugeführten Materialstrom gleichmäßig über den gesamten Umfang der Aufnahmetrommel zu verteilen. Dieser Verteiler kann drehbar gelagert sein, um bestimmte Materialarten optimal zu verteilen. Er kann aber auch fest an der Materialführungsfläche angeordnet sein. Wobei auch hier diese Befestigungsart für bestimmte Materialsorten besonders geeignet ist.According to an advantageous embodiment, the Material guide surface arranged a distributor. This distributor has the task of evenly feeding the material flow over the distribute the entire circumference of the take-up drum. This distributor can be rotated to optimally accommodate certain types of material to distribute. But it can also be fixed to the material guide surface be arranged. Here, too, this type of fastening for certain Types of material is particularly suitable.

Eine Weiterbildung der Erfindung sieht vor, die Aufnahmetrommel welche üblicherweise mit einem Panzerring versehen ist mit einem Sieb auszurüsten. Dieses Sieb hat den Vorteil, daß bereits beim Eintreten das Material entfeuchtet wird und die Feuchtigkeit rasch entfernt werden kann. Die Wanne, welchen einen Ablauf für die zentrifugierte Flüssigkeit aufweist, kann in einer vorteilhaften Weise mit einem Spülflüssigkeitszulauf versehen sein. Damit besteht die Möglichkeit, diese Wanne in gewissen Zeitabständen zu reinigen. Sofern der Spülflüssigkeitszulauf tangential an der Wanne angeordnet ist, entsteht ein Reinigungseffekt, welcher die gesamte innere Oberfläche der Wanne mit Reinigungsflüssigkeit benetzt und eine gleichmäßige Abreinigung gewährleistet. Der Schubboden ist in weiteren vorteilhaften Ausgestaltung der Erfindung auf drei Führungsbolzen gelagert. Dadurch wird ein Kippen oder Verkanten des Schubbodens wirksam verhindert.A development of the invention provides for the take-up drum which is usually provided with an armored ring with a sieve equip. This sieve has the advantage that when you enter it Material is dehumidified and the moisture can be removed quickly can. The tub, which has a drain for the centrifuged Has liquid can in an advantageous manner with a Be flushing liquid inlet. This gives you the opportunity to clean this tub at certain intervals. If the Flushing liquid inlet is arranged tangentially to the tub a cleaning effect that covers the entire inner surface of the The tub is wetted with cleaning fluid and is even Cleaning guaranteed. The walking floor is in another advantageous embodiment of the invention on three guide bolts stored. This will cause the push floor to tilt or tilt effectively prevented.
