Die Erfindung bezieht sich auf Spaltfilter, deren Filterfläche aus schraubenförmig auf einen Tragkörper gewickeltem Draht gebildet wird. Der Tragkörper besteht dabei aus zwei zylindrischen Stirnteilen und diese verbindenden Längsrippen, so daß die zu filtrierende Flüssigkeit zwischen den Längsrippen durchströmen kann.The invention relates to slotted filters, the filter surface of which is helical on a support body wound wire is formed. The support body consists of two cylindrical front parts and these connecting longitudinal ribs, so that the liquid to be filtered between the longitudinal ribs can flow through.
Wenn der die Filterfläche bildende Draht von einem Ende des Tragkörpers bis zum anderen aufgewickelt ist, muß die Drahtwicklung befestigt werden. Da es sich um sehr feinen Draht handelt, bietet eine sichere Befestigung Schwierigkeiten.When the wire forming the filter surface is wound from one end of the support body to the other the wire winding must be fastened. Since it is a very fine wire, offers secure fastening difficulties.
Gemäß der Erfindung ist in der Außenfläche einer Längsrippe eine Längsrille zur Aufnahme eines Verbindungsmittels, beispielsweise eines Klebstoffs oder Lötmittels, vorgesehen, das die über der Längsrille befindlichen Drahtteile erfaßt und mit der Längsrippe verbindet.According to the invention, a longitudinal groove for receiving a connecting means is in the outer surface of a longitudinal rib, for example an adhesive or solder, provided that the over the longitudinal groove Detected wire parts located and connects to the longitudinal rib.
Zur Ausführung dieser Verbindung kann Klebstoff nach dem Aufwickeln des Drahts in die Längs- ao rille eingebracht werden.To make this connection, glue can be used after winding the wire into the longitudinal ao groove are introduced.
Ein Lötmittel in Form von Lötdraht kann vor dem Aufwickeln in die Längsrille eingelegt werden. Es wird nach dem Wickelvorgang zum Schmelzen gebracht.A solder in the form of solder wire can be inserted into the longitudinal groove before winding. It is melted after the winding process.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung. Es zeigt The drawing illustrates an embodiment of the invention. It shows
F i g. 1 eine Aufsicht auf einen Tragkörper, teilweise mit Draht bewickelt,F i g. 1 is a plan view of a support body, partially wrapped with wire,
Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1,Fig. 2 is a section along the line II-II of Fig. 1,
F i g. 3 einen teilweisen Längsschnitt durch den Tragkörper in größerem Maßstab.F i g. 3 shows a partial longitudinal section through the support body on a larger scale.
Der Tragkörper? nach Fig. 1 besteht aus den beiden Stirnteilen la und Ib, die durch Längsrippen 8 verbunden sind. Diese Längsrippen 8 haben zu den Stirnteilen la und Ib hin verbreiterte Teile 8 a, die dadurch gebildet werden, daß die Seitenkanten 8 b mit ihren Endteilen 8 c zu den StirnteilenThe supporting body? according to Fig. 1 consists of the two end parts la and Ib, which are connected by longitudinal ribs 8. These longitudinal ribs 8 are to the end parts la and Ib through thickened portions 8a, which are formed by the side edges 8b with its end portions 8 to the end portions c
7 α und 7 b hin konvergieren.7 α and 7 b converge.
Die Filterfläche 11 wird durch eine Drahtwicklung gebildet. Die einzelnen Windungen 11 b sind auf den Stirnteilen la und Ib kreisrund, während sie im Bereich der Längsrippen eine polygonale Form haben (vgl. Fig. 2). Durch die verbreiterten TeileThe filter surface 11 is formed by a wire winding. The individual turns 11 b are circular on the end parts la and Ib , while they have a polygonal shape in the area of the longitudinal ribs (see FIG. 2). Because of the widened parts
8 a bzw. die Spitzbogenform der Endteile 8 c wird ein allmählicher Übergang von den kreisrunden auf die polygonalen Windungen lift erreicht, so daß der Abstand der Windungen 11 b, d. h. die Spaltweite des Filters an den Übergängen konstant bleibt.8 a or the ogival shape of the end parts 8 c, a gradual transition from the circular to the polygonal turns lift is achieved, so that the distance between the turns 11 b, ie the gap width of the filter at the transitions remains constant.

Flüssigkeit in das Innere des Tragkörpers 7 gelangen kann, sind Langlöcher 9 vorgesehen.Liquid can get into the interior of the support body 7, elongated holes 9 are provided.
In der Außenfläche einer Längsrippe 8 ist eine Längsrille 33 vorgesehen, die zur Aufnahme eines Verbindungsmittels dient. In dieser Längsrille 33 wird nach dem Aufwickeln des Drahts Klebstoff 34 eingebracht, der die Drahtwindungen 11 b im Bereich der Längsrille 33 umhüllt und sie mit den Rippen 8 bzw. dem Tragkörper 8 fest verbindet.In the outer surface of a longitudinal rib 8, a longitudinal groove 33 is provided, which serves to receive a connecting means. In this longitudinal groove 33, after the wire has been wound up, adhesive 34 is introduced, which envelops the wire windings 11 b in the region of the longitudinal groove 33 and firmly connects them to the ribs 8 or the support body 8.
Als Klebstoff kann ein Kunststoff benutzt werden.A plastic can be used as the adhesive.
In die Längsrille 33 kann auch vor dem Aufwikkeln des Drahts ein Lötdraht eingelegt werden, der nach dem Wickelvorgang beispielsweise mittels eines Lötkolbens erhitzt wird. Das Lötmittel schmilzt und dringt im Bereich der Rille in die Windungen 11 b ein, so daß diese nach dem Wiedererhärten des Lötmittels befestigt sind.A soldering wire can also be inserted into the longitudinal groove 33 before the wire is wound up, which wire is heated after the winding process, for example by means of a soldering iron. The solder melts and penetrates in the groove in the turns 11 b, so that these are fixed by the hardening of the solder again.
