Description

Dichtung zur Abdichtung einer Öffnung Seal for sealing an opening
Die Erfindung betrifft eine Dichtung zur Abdichtung einer Öffnung eines zumindest teilweise mit Fluid gefüllten Behältnisses, insbesondere einer Kühleinrichtung, mit einem Dichtkörper, wobei der Dichtkörper einen inneren Bereich und einen äußeren Bereich aufweist, wobei der Dichtkörper derart ausgestaltet ist, dass er von einem Gegenstand durchtretbar ist und wobei der Dichtkörper zumindest teilweise aus dehnbarem Material besteht.The invention relates to a seal for sealing an opening of an at least partially fluid-filled container, in particular a cooling device, with a sealing body, the sealing body having an inner region and an outer region, the sealing body being designed such that an object can pass through it is and wherein the sealing body consists at least partially of stretchable material.
Dichtungen der eingangs genannten Art sind aus der Praxis seit langem bekannt. Solchen Dichtungen werden vor allem bei der Extrusion von Erzeugnissen eingesetzt, wobei hierbei meist die Öffnung einer zur Kühlung des extrudierten Erzeugnisses dienenden Kühleinrichtung mit einer solchen Dichtung verschlossen wird. Das Erzeugnis, beispielsweise ein Rohr, wird mittels der Kühleinrichtung gekühlt, wobei die Kühleinrichtung ein Behältnis aufweist, dass zumindest teilweise mit Fluid gefüllt ist, z. B. mit Wasser zur Abkühlung des extrudierten Erzeugnisses. Insbesondere bei dem Einsatz einer solchen Dichtung bei der Extrusion mit einer Anlage, die einen kontinuierlich durchgeführten Dimensionswechsel des extrudierten Erzeugnisses ermöglicht, müssen solche Dichtungen besonders hohe Anforderungen erfüllen, um auch bei Dimensionswechseln eine hohe Dichtigkeit zu gewährleisten.Seals of the type mentioned have long been known in practice. Such seals are used primarily in the extrusion of products, in which case the opening of a cooling device used to cool the extruded product is usually closed with such a seal. The product, for example a pipe, is cooled by means of the cooling device, the cooling device having a container that is at least partially filled with fluid, e.g. B. with water to cool the extruded product. Particularly when using such a seal during extrusion with a system that enables a continuously carried out change of dimension of the extruded product, such seals have to meet particularly high requirements in order to ensure a high level of tightness even when changing dimensions.
Die bereits bekannten Dichtungen sind meist als Gummitrichter oder Gummiplatten ausgeführt, auf die Gewebebänder aufgenäht sind. Die in Längsrichtung angebrachten Gewebebänder sollen das sogenannte Rattern vermindern, da sie die Längsdehnung des Gummitrichters oder der Gummiplatte etwas begrenzen. Am inneren Bereich ist zumeist ebenfalls ein Gewebestreifen angeordnet, der dehnbar ist und einen direkten Kontakt des extrudierten Erzeugnisses mit dem Gummi des Dichtungsköpers vermeidet. Hierdurch gleitet das extrudierte Erzeugnis durch die Dichtung, ohne es zu stark in Längsrichtung zu dehnen und somit ein Rattern hervorzurufen. Bei den aus dem Stand der Technik bekannten Dichtungen ist häufig problematisch, dass diese im Betrieb, insbesondere bei Dimensionswechselanlagen, häufig Undichtigkeiten bei kleinen Dimensionen des Erzeugnisses zeigen, welche am unteren Randbereich des Einsatzgebiets liegen. Diese Undichtigkeiten treten besonders dann auf, wenn die Dichtung ein Vollbad abdichten soll, d. h., wenn das Behältnis vollständig mit Fluid gefüllt ist. Die bekannten Dichtungen bauchen dann sehr stark aus und werden undicht. Ferner ist das Rückstellverhalten dieser bekannten Dichtungen nicht besonders gut. So entstehen bei Dimensionswechseln von der größten bis zur kleinsten Dimension große Leckagen, so dass ein sicherer Betrieb der Dichtung und der Anlage, in der die Dichtung eingesetzt wird, nicht gewährleistet ist und die Qualität, insbesondere die Oberflächenqualität, des extrudierten Erzeugnisses leidet. Ein weiteres Problem ist, dass die Dichtungen bei großen Dimensionswechseln einreißen und dadurch unbrauchbarwerden.The already known seals are usually designed as rubber funnels or rubber plates, on which fabric tapes are sewn. The longitudinally attached fabric belts are said to reduce so-called chattering, since they somewhat limit the longitudinal expansion of the rubber funnel or the rubber plate. A fabric strip is usually also arranged on the inner area, which is stretchable and avoids direct contact of the extruded product with the rubber of the sealing body. As a result, the extruded product slides through the seal without stretching it too much in the longitudinal direction and thus causing rattling. It is often problematic with the seals known from the prior art that they often show leaks in operation, in particular in the case of dimensional change systems, in the case of small dimensions of the product which are located at the lower edge region of the area of use. These leaks occur particularly when the seal is intended to seal a full bath, ie when the container is completely filled with fluid. The known seals then bulge very much and become leaky. Furthermore, the reset behavior of these known seals is not particularly good. This leads to large leaks when changing dimensions from the largest to the smallest dimension, so that safe operation of the seal and the system in which the seal is used is not guaranteed and the quality, in particular the surface quality, of the extruded product suffers. Another problem is that the seals tear when there are large changes in dimension and are therefore unusable.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Dichtung zur Abdichtung einer Öffnung der eingangs genannten Art anzugeben, bei der ein sicherer Betrieb bei kostengünstiger Konstruktion und bei der eine gute Qualität eines mit der Dichtung zusammenwirkenden Erzeugnisses ermöglicht ist.The present invention is therefore based on the object of specifying a seal for sealing an opening of the type mentioned at the beginning, in which safe operation with inexpensive construction and in which good quality of a product interacting with the seal is made possible.
Erfindungsgemäß wird die voranstehende Aufgabe durch eine Dichtung zur Abdichtung einer Öffnung mit den Merkmalen des Patentanspruchs 1 gelöst. Danach ist die in Rede stehende Dichtung derart ausgestaltet und weitergebildet, dass der Dichtkörper mindestens ein, sich im wesentlichen vom inneren zum äußeren Bereich erstreckendes Steifungselement aufweist.According to the invention the above object is achieved by a seal for sealing an opening with the features of claim 1. The seal in question is then designed and developed in such a way that the sealing body has at least one stiffening element which extends essentially from the inner to the outer region.
In erfindungsgemäßer Weise ist zunächst erkannt worden, dass man für einen sicheren Betrieb der Dichtung und/oder einer Anlage, in der die Dichtung betrieben wird, übermäßige mechanische Belastungen der Dichtung vermeiden muss. Zudem muss zum Erhalt einer besonders guten Oberfläche eines extrudierten Erzeugnisses ein Abheben der Dichtung von dem extrudierten Erzeugnis beim Durchlaufen dieses Erzeugnisses durch die Dichtung vermieden werden. In erfindungsgemäßer Weise wird die mechanische Belastung der Dichtung dadurch reduziert, dass der Dichtkörper mit Steifungsele- menten versehen ist. Durch die Steifungselemente, beispielsweise durch das ausgewählte Biegungsverhalten und die umfängliche und/oder die radial Erstreckung der Steifungselemente bzw. deren Erstreckung vom inneren zum äußeren Bereich der Steifungselemente, kann in erfindungsgemäßer Weise das Dehnungsverhalten des Dichtkörpers eingestellt werden und somit beispielsweise eine mechanische Belastung der Dichtung durch ein Ausbauchen vermindert und/oder im wesentlichen vermieden werden. Die Dichtung liegt somit besonders gut am Gegenstand bzw. Erzeugnis an, wodurch eine gute Qualität des Erzeugnisses ermöglicht wird, da das Rattern vermindern wird.In the manner according to the invention, it was first recognized that one has to avoid excessive mechanical loads on the seal in order to operate the seal safely and / or in a system in which the seal is operated. In addition, in order to obtain a particularly good surface of an extruded product, it is necessary to avoid lifting the seal from the extruded product when this product passes through the seal. In a manner according to the invention, the mechanical load on the seal is reduced in that the sealing body with stiffening elements ment is provided. By means of the stiffening elements, for example the selected bending behavior and the circumferential and / or the radial extension of the stiffening elements or their extension from the inner to the outer region of the stiffening elements, the expansion behavior of the sealing body and thus, for example, a mechanical load on the seal can be adjusted reduced and / or substantially avoided by bulging. The seal thus lies particularly well on the object or product, which enables a good quality of the product, since the rattling is reduced.
Hinsichtlich einer besonders einfachen Ausgestaltung könnten die Steifungselemente am Dichtkörper angeordnet und mit diesem verbunden sein. Die Steifungselemente könnten hierbei beispielsweise in am Dichtkörper angeordneten Taschen angeordnet sein. Somit ließe sich die Steifungselemente austauschen und ließe sich der Dichtkörper dadurch an unterschiedlichste Aufgaben anpassen.With regard to a particularly simple embodiment, the stiffening elements could be arranged on the sealing body and connected to it. The stiffening elements could, for example, be arranged in pockets arranged on the sealing body. This means that the stiffening elements can be replaced and the sealing body can be adapted to a wide variety of tasks.
Im Hinblick auf eine besonders einfache Produktion könnten die Dichtungselemente integraler Bestandteil des Dichtkörpers sein. Beispielsweise könnte der Dichtkörper aus zwei Gummiplatten bestehen zwischen die ein oder mehrere Steifungselemente eingebracht werden, wobei die Gummiplatten durch geeignete Verfahren fest mit dem Gummi verbunden werden könnten.With a view to particularly simple production, the sealing elements could be an integral part of the sealing body. For example, the sealing body could consist of two rubber plates between which one or more stiffening elements are introduced, the rubber plates being able to be firmly connected to the rubber by suitable methods.
Es wäre von besonderem Vorteil, wenn vier Steifungselemente in Umfangsrichtung des Dichtungskörpers versetzt angeordnet wären. Es könnten allerdings auch lediglich zwei, drei oder mehr Steifungselemente vorgesehen sein. Über den Abstand zwischen den Steifungselementen könnte das Dehnungsverhalten des Dichtkörpers beeinflusst werden und exakt auf den Einsatzbereich abgestimmt werden. Zusätzlich oder alternativ könnte das Dehnungsverhalten auch durch die Form der Steifungselemente und/oder deren Größe eingestellt werden.It would be particularly advantageous if four stiffening elements were arranged offset in the circumferential direction of the sealing body. However, only two, three or more stiffening elements could also be provided. The expansion behavior of the sealing body could be influenced by the distance between the stiffening elements and matched exactly to the area of application. Additionally or alternatively, the expansion behavior could also be set by the shape of the stiffening elements and / or their size.
Im Rahmen einer besonders einfachen Ausgestaltung könnten die Steifungselemente im wesentlichen aus Metall und/oder Kunststoff bestehen. Hierdurch wäre eine beson- ders einfache und kostengünstige Herstellung der Steifungselemente sowie eine gute Verarbeitbarkeit gewährleistet.In the context of a particularly simple embodiment, the stiffening elements could essentially consist of metal and / or plastic. This would be a special ensures simple and inexpensive manufacture of the stiffening elements and good processability.
In vorteilhafter Weise könnte der Dichtkörper im Querschnitt im wesentlichen kreisförmig ausgestaltet sein. Der kreisförmige Querschnitt könnte insbesondere dann gegeben sein, wenn der Dichtkörper in Betrieb ist. Dies bedeutet, dass der Dichtkörper derart ausgestaltet sein könnte, dass er, wenn er nicht in Betrieb ist, in sich zusammenfällt, und somit keinen, im wesentlichen kreisförmigen Querschnitt aufweist. Der Dichtkörper wäre dann besonders optimal an kreisförmige Erzeugnisse, welche die Dichtung durchtreten, wie z. B. Rohre, angepasst.The sealing body could advantageously be designed essentially circular in cross section. The circular cross section could be given in particular when the sealing body is in operation. This means that the sealing body could be designed in such a way that it collapses when it is not in operation and thus does not have an essentially circular cross section. The sealing body would then be particularly optimal for circular products that pass through the seal, such as. B. pipes adapted.
In einer anderen Ausgestaltung könnte der Dichtkörper im Querschnitt im wesentlichen rechteckig ausgestaltet sein. Somit wäre der Durchtritt eines rechteckigen Gegenstands ermöglicht, wie beispielsweise einer Platte. Auch hier könnte der im wesentlichen rechteckige Querschnitt nur im Betrieb der Dichtung gegeben sein. Der Dichtkörper könnte im Querschnitt jedoch auch jede andere Form aufweisen. Die Form des Querschnitts könnte in vorteilhafter Weise auf die Form des Gegenstands, der die Dichtung durchtritt, abgestimmt sein.In another embodiment, the sealing body could be designed essentially rectangular in cross section. This would allow the passage of a rectangular object, such as a plate. Here, too, the essentially rectangular cross section could only exist during operation of the seal. In cross section, however, the sealing body could also have any other shape. The shape of the cross section could advantageously be matched to the shape of the object that passes through the seal.
In weiter vorteilhafter Weise könnte der Dichtkörper im wesentlichen trichterförmig ausgestaltet sein. Dies würde sich besonders gut auf das Dichtverhalten auswirken. Dabei könnte der äußere Bereich des Dichtkörpers einen größeren Durchmesser aufweist als der innere Bereich, wobei die Trichterform im Querschnitt jedwede Form aufweisen könnte. Alternativ könnte der Dichtkörper auch eine plattenförmige Ausgestaltung aufweisen, d.h. dass sich der Dichtkörper auch während des Betriebs im wesentlichen in einer Ebene mit oder im wesentlichen parallel zu der Wandung des Behältnisses erstreckt.In a further advantageous manner, the sealing body could be essentially funnel-shaped. This would have a particularly good effect on the sealing behavior. The outer area of the sealing body could have a larger diameter than the inner area, and the funnel shape could have any shape in cross section. Alternatively, the sealing body could also have a plate-shaped configuration, i.e. that the sealing body extends during operation essentially in one plane with or substantially parallel to the wall of the container.
Ferner könnte der Dichtkörper an seinem inneren Bereich ein vorzugsweise elastisches Gewebeband zur Herstellung eines verbesserten Kontakts zwischen Dichtkörper und Gegenstand aufweisen. Die Befestigung des äußeren Bereichs mit dem Behältnis könnte in jeder Form erfolgen, beispielsweise durch eine Klemmvorrichtung. Es könnte allerdings auch der innere Bereich des Dichtkörpers am Behältnis angeordnet und der äußere Bereich im dem Gegenstand in Kontakt sein.Furthermore, the sealing body could have a preferably elastic fabric band on its inner region for producing an improved contact between the sealing body and the object. The outer area could be fastened to the container in any form, for example by means of a clamping device. It could however, the inner area of the sealing body may also be arranged on the container and the outer area in the object may be in contact.
