Abstract
Description
Die Erfindung bezieht sich auf ein Filterelement gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a filter element according to the Preamble of claim 1.
Ein derartiges Filterelement ist durch die DE-OS 34 13 213 bekannt. Der Grund- oder Formkörper besteht hierbei aus kör nigem Polyäthylen, und die feinporige Schicht kann aus ei nem polymeren Fluorid, einem Plast, einem keramischen Stoff, insbesondere aber aus Polytetrafluoräthylen gebildet sein. Die Herstellung solcher Stoffe bzw. Materialien mit den ge wünschten Eigenschaften und in der gewünschten Korngröße ist aufwendig und teuer, demzufolge sind auch die Filter elemente, deren Grundkörper mit einer solchen feinporigen Schicht versehen sind, kostenintensiv.Such a filter element is through DE-OS 34 13 213 known. The basic or shaped body consists of kör nigem polyethylene, and the fine-pored layer can be made of egg a polymeric fluoride, a plastic, a ceramic material, but in particular be made of polytetrafluoroethylene. The production of such substances or materials with the ge desired properties and in the desired grain size is complex and expensive, therefore the filters elements whose basic body with such a fine-pored Layer are provided, expensive.
Der Erfindung liegt die Aufgabe zugrunde, die mit dem Grund körper zu verbindende feinporige Schicht aus einem Material herzustellen, das sowohl als solches als auch hinsichtlich seiner Verarbeitung zur gewünschten Partikelgröße ver gleichsweise kostengünstiger ist.The invention has for its object the reason Fine-pored layer to be connected from one material to manufacture, both as such and in terms of its processing to the desired particle size is equally cheaper.
Diese Aufgabe ist erfindungsgemäß durch die Merkmale gemäß dem kennzeichnenden Teil des Anspruchs 1 gelöst.According to the invention, this object is achieved by the features solved according to the characterizing part of claim 1.
Weiterbildungen und zweckmäßige Ausgestaltungen der Erfin dung sind in den Unteransprüchen charakterisiert.Further training and practical developments of the Erfin are characterized in the subclaims.
Die Erfindung wird im nachstehenden anhand der schemati schen Zeichnung erläutert. Es zeigtThe invention is based on the schemati drawing explained. It shows
Fig. 1 einen Teil eines Filterelements im Schnitt, Fig. 1 shows part of a filter element in section;
Fig. 2 einen Ausschnitt aus dem Grundkörper aus körnigem Polyäthylen mit einer aus feinsten Glasfasern bestehenden feinporigen Schicht in vergrößerter Darstellung, Fig. 2 shows a section of the base body of granular polyethylene with a finest glass fibers consisting of fine-pored layer in an enlarged scale;
Fig. 3 einen Ausschnitt gemäß Fig. 2, jedoch mit einer aus Graphit- und Kunststoffpulver bestehenden feinporigen Schicht, Fig. 3 shows a section according to FIG. 2, but with a group consisting of graphite and plastic powder finely porous layer,
Fig. 4 einen Ausschnitt gemäß Fig. 2, jedoch mit ei ner durch hochdisperse Kieselsäure und Kunst stoffpulver verkörperten feinporigen Schicht. Fig. 4 shows a detail according to FIG. 2, but with egg ner embodied by finely divided silica and plastic powder fine-pored layer.
Der aus Polyäthylen bestehende Grundkörper 10 des Filterele ments nach Fig. 1 weist balgförmig ausgebildete und aneinan dergereihte Filtersegmente 11 auf, die durch Innenkanäle 12 in Verbindung stehen. Diese Kanäle münden in einen nicht dar gestellten Hauptkanal.The existing polyethylene base body 10 of the Filterele ment according to Fig. 1 has bellows formed and aneinan dergereihte filter segments 11 which are provided through internal channels 12 in connection. These channels open into a main channel, not shown.
In die Außenflächen 13 der Filtersegmente ist eine feinporige Schicht eingesintert, die aus pulverisierten feinsten Glas fasern 14 besteht und/oder durch eine Mischung aus Graphit- und Kunststoffpulver 16 oder aus hochdisperser Kieselsäure und Kunststoffpulver 17 gebildet ist.In the outer surfaces 13 of the filter segments, a fine-pored layer is sintered, which consists of powdered finest glass fibers 14 and / or is formed by a mixture of graphite and plastic powder 16 or from highly disperse silica and plastic powder 17 .
Im Falle der Fig. 2 besteht die feinporige Schicht, die auf die Körper 15 des Grundkörpers 10 auf- bzw. zwischen diese ein gebracht ist, ausschließlich aus pulverisierten Glasfasern 14.In the case of FIG. 2, the fine-pored layer, which is brought up onto or between the bodies 15 of the base body 10 , consists exclusively of pulverized glass fibers 14 .
Beim Ausführungsbeispiel gemäß Fig. 3 ist die feinporige Schicht ausschließlich durch eine Mischung aus Graphit- und Kunststoffpulver 16 gebildet und im Falle der Fig. 4 be steht die feinporige Schicht ausschließlich aus hochdisperser Kieselsäure und Kunststoffpulver 17.In the embodiment according to FIG. 3, the fine-pored layer formed exclusively by a mixture of graphite and plastic powder 16 and in the case of Fig. 4 is the fine pored layer be exclusively of highly disperse silica and plastic powder 17th
Es besteht ohne weiteres auch die Möglichkeit, die feinporige Schicht aus irgend einem geeigneten Mischungsverhältnis der im vorstehenden genannten Komponenten zu bilden. So kann die feinporige Schicht beispielsweise etwa zu gleichen Anteilen aus pulverisierten Glasfasern 14, aus Graphit- und Kunststoff pulver 16 und aus hochdisperser Kieselsäure und Kunststoff pulver 17 bestehen. Die dünne, feinporige Schicht wird dabei zweckmäßigerweise so mit dem Grundkörpermaterial durch Sin terung oder Klebung verbunden, daß dessen Porengröße wenig stens auf ein Fünftel ihrer ursprünglichen Größe reduziert wird.It is also readily possible to form the fine-pored layer from any suitable mixing ratio of the components mentioned above. For example, the fine-pored layer may consist of powdered glass fibers 14 , graphite and plastic powder 16, and highly disperse silica and plastic powder 17 in approximately equal proportions. The thin, fine-pored layer is expediently connected to the base material by sintering or gluing in such a way that its pore size is reduced to at least a fifth of its original size.
Das Kunststoffpulver kann aus einem geeigneten Polymeri sat, einer Polyadditionsverbindung oder aus einem Polykon densat hergestellt sein, zum Beispiel aus einem Polymeth acrylsäureester, aus Polyurethan oder aus Polykarbonat. Zweckmäßigerweise wird für das die feinporige Schicht mit bildende Kunststoffpulver ein solches gewählt, dessen Schmelzpunkt höher liegt als derjenige des Grundkörperma terials.The plastic powder can be made of a suitable polymer sat, a polyaddition compound or from a polycon densat be made, for example from a polymeth acrylic acid esters, made of polyurethane or polycarbonate. The fine-pored layer is expediently used for this forming plastic powder chosen one whose Melting point is higher than that of the basic body terials.
