Description
Filterdüsse für Waseraufbereichtungsanlagen und dgl. Filter nozzles for water treatment systems and the like.
Die Erfindung betrifft eine Filterdüse für Wasseraufbereitungsanlagen und dgl., die aus einem Tragkörper, einem oder mehreren mit Filterschlitzen versehenen Mantelstücken und aus einem Eopfteil besteht. Derartige Filterdüsen werden vorzugsweise aus zähelastischem Kunststoff hergestellt.The invention relates to a filter nozzle for water treatment systems And the like. Made up of a support body, one or more provided with filter slots Coat pieces and consists of a head part. Such filter nozzles are preferred made of tough elastic plastic.
Bekannte Filterdüsen dieser Art haben den Nachteil, daß die mit Filterschlitzen versehenen Nantelstücke durch das auf einen Gewinde schaft des Tragkörpers aufgeschraubte Kopfstück zusaniniengehalten werden. Die Herstellung dieser Schraubverbindung ist relativ kostspielig und hat außerdem den Nachteil, daß für jede Düsenlänge, die sich aus der Anzahl der übereinander angeordneten Nantelstücke ergibt, ein besonderer Tragkörper mit einem entsprechend lang bemessenen Gewindeschaft angefertigt werden nuß.Known filter nozzles of this type have the disadvantage that those with filter slots provided Nantelstück by screwed onto a threaded shaft of the support body Head piece to be held together. The manufacture of this screw connection is relatively expensive and also has the disadvantage that for each nozzle length that a special one results from the number of noseband pieces arranged one above the other Carrying body can be made with an appropriately long threaded shaft nut.
Ein weiterer Nachteil bekannter Filterdüsen besteht darin, daß sich die zylindrischen oder leicht konischen Mantelstücke unter der Einwirkung des oft hohen Betriebsdruckes der Anlage leicht verformen, d.h. eine ovale Form annehmen, was zur Folge hat, daß sich die Filterschlitze in den zu stark gekrümmten Bereichen der Mantelfläche verengen oder gar vollständig schließen, während sich die Schlitze im Bereich der abgeflachten Steile der Mantelfläche in unerwünschter Weise verbreitem und somit die Filterwirkung der Düse beeinträchtigt wird.Another disadvantage of known filter nozzles is that the cylindrical or slightly conical casing pieces under the action of the oft slightly deform the system under high operating pressure, i.e. adopt an oval shape, which has the consequence that the filter slots in the excessively curved areas constrict the lateral surface or even close it completely, while the slots widen in an undesirable manner in the area of the flattened part of the lateral surface and thus the filter effect of the nozzle is impaired.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die vorerwähnten Nachteile bekannter Filterdüsen zu beheben.The present invention is therefore based on the object of the aforementioned To remedy the disadvantages of known filter nozzles.
Die Lösung dieser Aufgabe besteht zunächst darin, daß die aus zähelastischem Kunststoff, wie Polypropylen, hergestellten Teile der Filterdüse mit nicht oder nur schwer lösbaren Schnappverbindungsmittelns wie Ringnuten und darin einschnappenden Ringwulsten, ausgestattet sind. Durch diese Ausgestaltung kommen die bisher üblichen und teuren Schraubverbindungen in Fortfall. Ferner ist für alle praktisch vorkommenden Disenlangen nur eine einzige Ausführungsform des Tragkörpers erforderlich.The solution to this problem is first of all that the viscoplastic Plastic, such as polypropylene, made parts of the filter nozzle with no or snap connection means that are difficult to detach, such as ring grooves and snapping into them Annular beads, are equipped. This configuration results in the usual ones and expensive screw connections are no longer necessary. Furthermore, it is practically occurring for all Only a single embodiment of the support body is required over this length.
Ein weiteres Merkmal der Erfindung besteht darin, daß im Innern der Nantelstücke des Filters gelochte Versteifungsringe oder -scheiben vorgesehen sind. Durch diese Ausgestaltung werden unerwünschte Verformungen und damit Veränderungen der Filterschlitzbreiten wirksam vermieden.Another feature of the invention is that inside the Perforated stiffening rings or stiffening disks are provided in the shell pieces of the filter. This configuration causes undesirable deformations and thus changes the filter slot widths effectively avoided.
In der Zeichnung ist die Erfindung an einem Ausführuiigsbeispiel veranschaulicht. Es zeigen: Fig. 1 eilen Längsschnitt durch die Teile einer Filterdüse mit zwei Filermantelstücken, Fig. 2 eine Draufsicht auf ein Filtermantelstück nach Fig. 1.In the drawing, the invention is illustrated using an exemplary embodiment. 1 shows a longitudinal section through the parts of a filter nozzle with two pieces of filter jacket, Fig. 2 shows a plan view of a filter jacket piece according to FIG. 1.
Gemäß Fig. 1 besteht die Filterdüse aus einem Tragkörper 1, zwei mit Filterschlitzen 21 versehenen Nantelstücken 2 und einem Kopfteil 3, das radial verlaufende Filterschlitze 31 auSweist. Der Tragkörper 1 ist in bekannter Weise mit einem Stutzen 11 zum Anschluß an eine Rohrleitung versehen.According to Fig. 1, the filter nozzle consists of a support body 1, two with Filter slits 21 provided with pieces 2 and a head part 3, which extends radially Filter slots 31 has. The support body 1 is provided with a connecting piece in a known manner 11 provided for connection to a pipeline.
Nach der Erfindung sind die leicht konischen Filtermäntel 2 an einer Stirnseite mit einer nach innen offenen Ringnut 22 und an der gegenüberliegenden Stirnseite mit einer nach außen vorspringenden Ringwulst 23 versehen. Ferner weist der Tragkörper 1 an seiner Stirnseite eine nach außen vorspringende Ringwulst 13 und das Kopfteil 3 an seiner Stirnseite eine nach innen offene Ringnut 32 auf. Sämtliche Ringnuten 22 und 32 sowie die Ringwulste 13 und 23 sind gleich bemessen und so geformt, daß sich letztere nur unter Aufwendung einer erheblichen Druckkraft in die Nuten 22 bzw. 32 einfedern und sich nur sehr schwer oder überhaupt nicht wieder aus den Nuten entfernen lassen.According to the invention, the slightly conical filter jackets 2 are on one End face with an inwardly open annular groove 22 and on the opposite one The end face is provided with an outwardly protruding annular bead 23. Also has the support body 1 has an outwardly projecting annular bead 13 on its end face and the head part 3 has an inwardly open annular groove 32 on its end face. All Annular grooves 22 and 32 as well as the annular beads 13 and 23 are dimensioned the same and shaped so that that the latter can only be moved into the grooves with the application of a considerable compressive force 22 or 32 and only very difficult or not at all to get out of the Have the grooves removed.
In den Filtermänteln 2 ist an einer Stirnseite je ein mit Löchern oder Schlitzen 24 versehener Versteifungsring 25 vorgesehen, der zusammen mit dem Mantel 2 einstückig im Spritzverfahren hergestellt ist.In each of the filter jackets 2 there is one with holes on one end face or slits 24 provided stiffening ring 25 provided together with the Sheath 2 is made in one piece by injection molding.
aturgemaB sind die Ausführungsmöglichkeiten der Erfindung durch das dargestellte Ausführungsbeispiel nicht erschöpft. So ist es möglich, die Filterdüse durch Verwendung einer größeren Anzahl von Filtermänteln 2 in jeder gewünschten Länge auszubilden. Ferner können zur Erzielung einer schwer oder nicht lösbaren Verbindung zwischen den Teilen 1 bis 3 der Filterdüse anstelle der gezeigten Ringwulste 13-und 23 und der Ringnuten 22 und 32 andere geeignete Mittel, wie federnde, hakenförmige Vorsprünge und Hinterschneidungen zum Einrasten dieser Vorsprünge vorgesehen werden. Auch können anstelle der gelochten Ringe 25 gelochte Scheiben in den Filtermänteln 2 vorgesehen werden.AturgemaB are the implementation possibilities of the invention through the illustrated embodiment not exhausted. So it is possible to use the filter nozzle by using a larger number of filter jackets 2 in any desired Train length. Furthermore, to achieve a difficult or impossible to solve Connection between parts 1 to 3 of the filter nozzle instead of the annular beads shown 13 and 23 and the annular grooves 22 and 32 other suitable Means how resilient, hook-shaped projections and undercuts for engaging these projections are provided. Perforated disks can also be used instead of the perforated rings 25 are provided in the filter jackets 2.
Schließlich können anstelle der gelochten Ringe oder Scheiben in den Filtermänteln geschlossene Platten vorgesehen werden, die einen äußeren Abschluß der Düse darstellen und damit das Kopfteil 3 entbehrlich machen.Finally, instead of the perforated rings or discs in the Filter jackets closed plates are provided which have an outer seal represent the nozzle and thus make the head part 3 unnecessary.
