Abstract
Description
Die Erfindung bezieht sich auf ein Filterelement für Gase oder Flüssigkeiten mit in der Form eines Ringes angeordnetem, gefalteten Filtermaterial, das von außen nach innen durchströmbar ist, und das zwischen einem inneren, perforierten, zylindrischen Trag körper und einem perforierten, zylindrischen Außenmantel angeordnet ist, der durch Biegen aus einem perforierten Flachmaterial hergestellt ist, und dessen aneinander anschließende Kanten miteinander verbunden sind.The invention relates to a filter element for gases or liquids in the Form of a ring arranged, pleated filter material that goes from the outside in is flowable, and that between an inner, perforated, cylindrical support body and a perforated, cylindrical outer jacket is arranged through Bending is made of a perforated flat material, and its together subsequent edges are connected.
Bei einem bekannten Filterelement dieser Art (US-PS 3 241 680) ist der Ring aus sternförmig gefaltetem Filtermaterial in axial beabstandeten Windungen von einem schraubenlinienförmig darum herumgewickelten Band umgeben. Über diesen aus Tragkörper, Filtermaterial und Band bestehenden Körper ist ein zylindrischer, perforier ter Außenmantel geschoben, der aus einem hinsichtlich Durchmesser und axialer Länge den Abmessungen des Körpers angepaßten Zuschnitt aus perforiertem Flach material hergestellt ist, und dessen in axialer Richtung verlaufende Kanten in zu einem Zylinder gebogenem Zustand überlappend miteinander verbunden sind, wobei Band und Außenmantel miteinander verklebt sind. Nachteilig an dieser Ausführung ist ins besondere, daß für jede Größe, Durchmesser und axiale Länge, des Filterelements ein hinsichtlich der Abmessungen angepaßter Zuschnitt aus perforiertem Flachmaterial benötigt wird. Außerdem muß ein Absatz im Bereich der Überlappung der axialen Kanten des Zuschnitts angeformt werden, damit sich eine glatte, zylindrische Innen fläche des Außenmantels ergibt.In a known filter element of this type (US Pat. No. 3,241,680) the ring is made filter material folded in a star shape in axially spaced turns of one helically wrapped around it. About this one Carrying body, filter material and band existing body is a cylindrical, perforier ter outer sheath, which consists of a diameter and axial Cut from perforated flat to the size of the body Material is made, and its axially extending edges in one Cylinder bent state are overlapped together, band and the outer jacket are glued together. The disadvantage of this version is ins special that for any size, diameter and axial length, the filter element cut to size from perforated flat material is needed. In addition, a paragraph in the area of the overlap of the axial Edges of the blank are molded to create a smooth, cylindrical interior surface of the outer jacket results.
Aufgabe der Erfindung ist es, die Herstellung des Außenmantels und damit des ganzen Filterelements zu vereinfachen.The object of the invention is to produce the outer jacket and thus the whole Simplify filter elements.
Diese Aufgabe ist bei einem Filterelement der eingangs genannten Art dadurch gelöst, daß das perforierte Flachmaterial ein aus Kunststoff bestehender Streifen ist, der schraubenförmig in die Form eines Zylinders gewickelt ist, und dessen schraubenlinien förmig verlaufende, aneinander anschließende Kanten durch eine Vergußmasse aus Kunststoff miteinander verbunden sind. With a filter element of the type mentioned at the outset, this object is achieved by that the perforated sheet is a plastic strip, the is helically wound into the shape of a cylinder, and its helical lines shaped, adjoining edges from a potting compound Plastic are interconnected.
Das perforierte Flachmaterial aus Kunststoff kann auch die Form eines flachen Gitters aus Kunststoff haben.The perforated plastic sheet material can also take the form of a flat grid made of plastic.
Damit können Filterelemente beliebiger Abmessungen, Durchmesser und axiale Länge, aus einem stets gleichen Streifen perforierten Flachmaterials hergestellt werden. Allerdings ist es auch schon bekannt (US-PS 4 969 999) einen zylindrischen Mantel, der als Außenmantel eines Filterelements der eingangs genannten Art verwendbar sein könnte, aus einem zu einem Zylinder gebogenen, siebartigen Metallzuschnitt dadurch herzustellen, daß dessen in gebogenem Zustand aneinander anschließende, in axialer Richtung verlaufende Kanten in einen parallel dazu angeordneten, im Querschnitt H-förmigen Verbindungsstreifen aus thermoplastischem Werkstoff eingeführt und durch Hitze und Druck der Verbindungsstreifen und die Kanten miteinander verbunden werden.Filter elements of any dimensions, diameter and axial length, be made from the same strip of perforated flat material. However, it is also already known (US Pat. No. 4,969,999) a cylindrical jacket, which can be used as the outer jacket of a filter element of the type mentioned could, from a sieve-like metal blank bent into a cylinder produce that its adjoining in the bent state, in the axial Edges running in the direction of a parallel cross-section H-shaped connecting strips made of thermoplastic material introduced and through Heat and pressure of the connecting strips and the edges joined together will.
Tragkörper und Außenmantel können vorzugsweise die Form von Kreiszylindern oder auch die Form ovaler Zylinder haben.Support body and outer jacket can preferably take the form of circular cylinders or also have the shape of oval cylinders.
Das gefaltete Filtermaterial kann vorzugsweise aus Papier oder auch aus Vlies beste hen.The pleated filter material can preferably be made of paper or nonwoven hen.
Die schraubenlinienförmig verlaufenden Kanten des Streifens können vorzugsweise stumpf oder auch überlappend aneinander anschließen.The helical edges of the strip can preferably Connect blunt or overlapping.
In der Zeichnung ist ein Ausführungsbeispiel eines Filterelements nach der Erfindung mit zwei alternativen Möglichkeiten für das Anschließen der Kanten des Streifens aneinander dargestellt, und zwar zeigtIn the drawing is an embodiment of a filter element according to the invention with two alternative ways of connecting the edges of the strip shown together, and shows
