Abstract
Description
Filtervorrichtung, insbesondere für Drainagerohre Die Erfindung betrifft eine Filtervorrichtung, insbesondere für Drainagerohre. Filtervorrichtungen dieser Gattung werdem zum Abdecken von Drainagerohren, zu Herumlegen um Drainagerohre und zur Befestigung von Grabenwänden und Kanalsohlen o.dgl. verwendet.Filter device, particularly for drainage pipes The invention relates to a filter device, especially for drainage pipes. Filter devices of this Genus are used to cover drainage pipes, to lay around drainage pipes and for fastening trench walls and channel bottoms or the like. used.
Es sind verschiedene Ausführungen dieser Filtervorrichtungen bekannt. In allen Fällen soll vom Aufbau der Matte her erreicht werden, daß sich bei der Anwendung gute Filtereigenschaften ergeben. Various designs of these filter devices are known. In all cases, the structure of the mat should ensure that the Application result in good filter properties.
Der Erfindung liegt die Aufgabe zugrunde, eine Filtervorrichtung der vorbezeichneten Gattung zu schaffen, die sich durch gute und einstellbare Filtereigenschaften auszeichnet, die sich in einem kontinuierlichen Herstellungsverfahren aufgrund der gewählten Materialien besonders preisgünstig herstellen läßt und von Anfang an eine gute hydraulische Wirkung aufweist. The invention is based on the object of a filter device of the aforementioned type, which are characterized by good and adjustable filter properties is characterized by a continuous manufacturing process due to the Chosen materials can be produced particularly inexpensively and from the beginning a quality Has hydraulic effect.
Die Aufgabe ist dadurch gelöst worden, daß die Filtervorrichtung mindestens eine Schicht aus Kokosfasern aufweist. Ein Vorteil dieser Ausbildung besteht darin, daß die Kokosfasern neben ihrer Preisgünstigkeit sowohl gute hydraulische als auch Filtereigenschaften, wenn auch in geringen Maßen, aufweisen und außerdem aufgrund ihrer Lange gut fixierbar, d.h. zum Beispiel gut vernadelbar sind, so daß die so ausgebildete Filterschicht ei#ne ausreichende Eigenfestigkeit aufweist. Die bei Verwendung von Kokosfasern sofort auftretende hydraulische Wirkung bei der Verwendung als Schicht für Drainageeinrichtungen ist ein Vorteil gegenüber textilen Filterschichten, z.B. Filz, wo die volle hydraulische Wirkung der Drainageeinrichtung erst nach Verrottung der Textilschicht eintritt. The object has been achieved in that the filter device has at least one layer of coconut fibers. An advantage of this training consists in the fact that coconut fibers are not only inexpensive but also have good hydraulic properties as well as filter properties, albeit to a small extent, and moreover easy to fix due to their length, i.e. for example easy to needles, so that the filter layer formed in this way has sufficient inherent strength. the When using coconut fibers, hydraulic effect occurs immediately when used as a layer for drainage devices is an advantage over textile filter layers, e.g. felt, where the full hydraulic effect of the drainage device only after rotting the textile layer occurs.
Die Filtervorrichtung kann in Weiterbildung der ErfinRung als Kombinationsfilter ausgebildet sein, der aus Kokosfasern, Styromull oder Hygromull, Torf und Zellwolle sowie aus Filterschichten aus Häcksel aufgebaut ist. In a further development of the invention, the filter device can be used as a combination filter made of coconut fibers, styrofoam or hygromull, peat and rayon and is made up of filter layers made of chaff.
Vorzugsweise bildet man die Filtervorrichtung so aus, daß das Material mit der feineren Struktur weiter außen zu liegen kont und nach innen hin immer gröber wird, so daß eine Filtervorrichtung entsteht, die ähnlich einem Brunnenfilter aufgebaut ist. Durch verschiedene Mengenanteile der vorbenannten Filterkomponenten innerhalb des Kombinationsfilters kann eine Filtervorrichtung geschaffen werden, die den speziellen Anforderungen bezüglich hydraulischer Wirkung, Filtereigenschaften und Lebensdauer individuell angepaßt werden kann.The filter device is preferably designed in such a way that the material With the finer structure, it is contorted to lie further outside and increasingly coarser towards the inside so that a filter device is created which is similar to a well filter built up is. Through different proportions of the aforementioned filter components within of the combination filter, a filter device can be created that the special Requirements regarding hydraulic effect, filter properties and service life can be customized.
Die iiltervorrichtung kann als Matte hergestellt werden oder als Ummantelung um Drainagerohre gefertigt werden. In der Filterschicht können die einzelnen Komponenten in Schichten oder miteinander vermischt angeordnet werden. Um die mechanische Festigkeit zu erhöhen, können zusätzlich um die Ummantelung des Drainagerohres Fäden herumgeführt werden. The filter device can be manufactured as a mat or as a Sheathing to be made around drainage pipes. In the filter layer, the individual Components are arranged in layers or mixed together. To the mechanical To increase strength, threads can also be placed around the casing of the drainage pipe be shown around.
In die Filterschichten können zur Verstärkung der mechanischen Festigkeit auch Fäden und/oder längere Fasern eingelegt werden, die aus verrottbarem oder nicht verrottbarem Material bestehen. In the filter layers can be used to strengthen the mechanical strength also threads and / or longer fibers are inserted, which are made of decay or not consist of rotting material.
In einer anderen Lösung der gestellten Aufgabe, für die auch selbständiger Schutz beansprucht wird, ist eine Filtervorrichtung geschaffen worden, die mindestens eine Schicht aus Palmfasern aufweist. Aus Kostengründen und zur weiteren individuellen Anpassung der Filtervorrichtung an die speziellen Anforderungen können die Palmfasern die Kokosfasern ersetzen oder mit diesen vermischt werden. In another solution of the task at hand, for which also more independently Protection is claimed, a filter device has been created that at least has a layer of palm fiber. For reasons of cost and for further individual The palm fibers can adapt the filter device to the special requirements replace the coconut fibers or mixed with them will.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt, die nur beispielhaft für die verschiedenen Kombinationsmöglichkeite# der Anordnung der einzelnen Filterkomponenten aufgezeichnet sind. Es zeigen: Xig. 1 eine Ausbildung der Filtervorrichtung als Ummantelung eines Drainagerohre 5 und Fig. 2 eine Ausbildung der Filtervorrichtung als Matte. In the drawing, two exemplary embodiments of the invention are shown, which are only an example of the various possible combinations # of the arrangement of the individual filter components are recorded. It show: Xig. 1 an apprenticeship the filter device as a sheathing of a drainage pipe 5 and FIG. 2 shows an embodiment the filter device as a mat.
Bei der Ausbildung nach Fig. 1 ist das Filterrohr mit 1 bezeichnet, das Wasserdurchlaufrillen 2 aufweist und die um das Filterrohr 1 herumgelegte Filtervorrichtung aus einer innen liegenden Zellwollschicht 3, einer mittleren Torfschicht 4 und einer außen liegenden Kokosfaserschicht 5 besteht. Zur Erzeugung einer größeren mechanischen Festigkeit ist die äußere Kokosfaserschicht 5 in sich vernadelt. In the embodiment according to Fig. 1, the filter tube is denoted by 1, the water passage grooves 2 and the filter device placed around the filter tube 1 from an inner layer of viscose wool 3, a middle peat layer 4 and one outer coconut fiber layer 5 is made. To produce a larger mechanical Strength is the outer coconut fiber layer 5 needled in itself.
Fig. 2 zeigt die Filtervorrichtung in Mattenform, wobei die innere Schicht aus Zellwolle 3 hergestellt ist und die äußere Schicht aus in sich vernadelten Kokosfasern 5 besteht. Die Vernadelung 6 ist nur schematisch eingezeichnet. Zwischen diesen beiden Schichten ist eine Schicht aus Torf 4 angeordnet. Fig. 2 shows the filter device in mat form, the inner Layer of rayon 3 is made and the outer layer of needled in itself Coconut fiber 5 is made. The needling 6 is only shown schematically. Between these two layers a layer of peat 4 is arranged.
