Description

P A T E N T A N S P R U C H : Filter nach Patent 646 508 für gasförmige Stoffe und in Schichtquerrichtung vom Gas durchströmten Bändern, dadurch gekennzeichnet, daß je zwei schraubenförmig gewundene Bänder durch einen schraubenförmig gewundenen Draht verbunden sind, welcher den gleichen Durchmesser und die gleiche Steigung wie die Bänder besitzt. P A T E N T A N S P R U C H: Filter according to patent 646 508 for gaseous Substances and bands through which the gas flows in the transverse direction of the layers, characterized in that that each two helically wound bands through one helically wound Wire are connected, which have the same diameter and the same pitch how the tapes owns.

Filter für gas@@@@@ge Stoffe Zusatz, zur patent 646 50S Gegenstand des Hauptpatents ist ein Luftfilter, das aus reihenweise nebeneinandergelagerten, schraubienförmig gewundenen Bändern besteht, durch welche die zu reinigende Luft senkrecht zur Schichtlage hindurchströmt, dessen wesentliche Merkmale darin bestehen, daß die in axialer Richtung gemessene Breite b der gewundenen Bänder gleich dem Abstand a der einzelnen Windungen voneinander und vorzugsweise auch gleich dem Windungsdurchmesser d bemessen ist.Filter for gas @@@@@ ge substances additive to patent 646 50S subject of the main patent is an air filter that consists of rows of, There are helically wound bands through which the air to be cleaned flows through it perpendicular to the layer, the essential characteristics of which are: that the measured in the axial direction width b of the winding bands equal to that Distance a of the individual turns from one another and preferably also equal to the turn diameter d is dimensioned. Die günstige Wirkung der mit diesem Verhältnis der Abmessungen ausgestatteten Schraubenbänder kommt erst dann ganz zur Geltung, wenn die einzelnen Filterelemente derart nebeneinandergelegt werden, daß an den Berührungsstellen das gewundene Band des einen Filtereiementes einer für den Gasstrom frei gelassenen Lücke des benachbarten Filterelementes gegenüberliegt. Es wird dann der von dem Rücken des Bandes eines Filterelementes abgleitende Gasstrom unmittelbar mit geringer Hemmung in die benachbarte Durchströmöffnung abgelenkt. Dies wäre z. B. nicht der Fall, wenn die Bänder des benachbarten Filterelementes unmittelbar nebeneinanderliegen würden oder auch sonst irgendwie gegeneinander versetzt wären. The beneficial effect of those equipped with this ratio of dimensions Screw straps only come into their own when the individual filter elements are placed side by side in such a way that at the points of contact the wound tape of a filter element of a gap left free for the gas flow in the neighboring one Filter element opposite. It then becomes the one from the back of the tape Filter element sliding gas flow directly with little inhibition in the neighboring Diverted flow opening. This would be e.g. B. not the case if the ligaments of the adjacent filter element would be directly next to each other or otherwise would somehow be offset against each other. Um diese gewünschte zwangsläufige Lage der Filterelemente gegeneinander zu gewährleisten, werden dieselben derart miteinander verbunden, daß eine zusammenhängende feste Matte entsteht. Hierzu wird ein schraubenförmig gewundener Draht verwendet, welcher den gleichen Windungsdurchmesser d und die gleiche Steigung (a + b = 2 d) wie das schraubenförmig gewundene Band (vgl. Abb. I und 2) besitzt. Ein derart bemessener Draht geht genau passend und ohne Spielraum zwischen zwei nebeneinandergelegten Bändern hindurch. Eine mehrfache Wiederholung der Verflechtung der Bänder mit den Drähten gibt zwangsläufig ein Filtergewebe, wie aus der Abb. 2 ersichtlich ist. To this desired inevitable position of the filter elements against each other to ensure, the same are connected to each other in such a way that a coherent solid mat is created. A helically wound wire is used for this, which has the same coil diameter d and the same pitch (a + b = 2 d) like the helically wound band (see Fig. I and 2). Such a sized one Wire goes exactly fitting and with no leeway between two juxtaposed Ribbons through. A multiple repetition of the interweaving of the ligaments with the Wires are inevitably a filter fabric, as can be seen in Fig. 2.
