Description
Spailfilterkörper Die Erfindung bezieht sich auf einen Spaltfilterkörper, insbesondere zur Feinfilterung von Flüssigkeiten und Gasen, bei welchem die Spalte durch schneidenförmige Kanten am äußeren Umfang der Filterelemente gebildet werden. Die Erfindung bezweckt eine besonders einfache Konstruktion, welche nur geringen Materialaufwand erfordert, eine leichte Herstellbarkeit ermöglicht und gleichzeitig eine sehr feine Filterung erlaubt. Die Erfindung besteht darin, daß die Filterelemente durch einz eine gefaltete Streifen bzw. durch einen spiralförmig gewundenen ge falteten Streifen gebildet werden.Spail filter body The invention relates to a gap filter body, especially for fine filtering of liquids and gases, in which the column be formed by cutting edges on the outer periphery of the filter elements. The invention aims at a particularly simple construction, which is only minor Requires material expenditure, enables easy manufacturability and at the same time a very fine filtering allowed. The invention consists in that the filter elements by a single folded strip or by a spiral wound ge Stripes are formed.
Die bekannten Spaltfilter, welche ebenfalls aus einzelnen Ringen oder aus einem spiralförmig gewundenen Band hergestellt werden, weisen in der Regel ein besonderes Profil auf, daß eine besondere Bearbeitung der Ringe oder Bänder zur Erzielung des gewünschten Querschnittes, insbesondere auch von schneidenförmigen Kanten an den engsten Stellen des Flüssigkeitsdruchtritts erfordert. Demgegenüber können die Elemente des erfindungsgemäßen Spaltfilters aus einfachen Bandprofilen hergestellt werden, indem diese lediglich V-förmig gefaltet werden, im übrigen jedoch keine oder nur geringfügige Bearbeitnng benötigen. The well-known slotted filter, which also consists of individual rings or made from a spirally wound ribbon, usually have a special profile on that a special processing of the rings or bands to achieve the desired cross-section, in particular also knife-edge Requires edges at the narrowest points of the liquid passage. In contrast the elements of the gap filter according to the invention can be made from simple strip profiles are made by merely folding them in a V-shape, but otherwise require little or no editing.
Dile Schlitze sind hierbei vorteilhaft in Ebenen senkrecht zur Filterachse angeordnet. Dile slots are advantageous here in planes perpendicular to the filter axis arranged.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. An exemplary embodiment of the invention is shown in the drawing.
Der Filterkörper ist hilerbei durch ein V-förmig gefaltetes flaches Band 1 gebildet, welches in bekannter Weise zu einer Spirale aufgewunden sein kann. The filter body is supported by a V-shaped folded flat Band 1 is formed, which can be wound into a spiral in a known manner.
Infolge der V-förmigen Faltung der Filterelemente 1 ragen die engsten Dulrchtrittsquerschnitte radial nach außen über den sonstigen Filterkörper hinaus, so daß innerhalb der einzelnen Faltungen Taschen 2 gebildet werden, die das Absetzen von Unreinigkeiten beim Durchtritt der Flüssigkeit in Pfeilrichtung durch die Spalte 3 in zweckmäßiger Weise begünstigen. As a result of the V-shaped folding of the filter elements 1, the narrowest protrude Passage cross-sections radially outwards beyond the rest of the filter body, so that pockets 2 are formed within the individual folds, which the settling of impurities when the liquid passes through the gap in the direction of the arrow 3 favor in an appropriate manner.
