Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die konzentrischen bezw. spiralförmigen Rippen d ,an den die Filterschichten trennenden Böden, brauchen nicht, wie in der Zeichnung des Hauptpatents dargestellt ist, eine stetig verlaufende Kurve (z. B. Kreis) zu bilden, sondern sie können mehr oder weniger scharfe Biegungen oder auch Ecken aufweisen und auch geradlinig verlaufen.The concentric respectively. Spiral ribs d on the bottoms separating the filter layers do not need to form a continuous curve (e.g. circle), as is shown in the drawing of the main patent, but they can have more or less sharp bends or corners and also run in a straight line.
In der Zeichnung deuten die Pfeile die Richtung der abfließenden filtrierten Flüssigkeit an. Die Zuführung der Flüssigkeit erfolgt in der der Pfeilrichtung entgegengesetzten Richtung.In the drawing, the arrows indicate the direction of the filtered liquid flowing out at. The liquid is supplied in the direction opposite to that of the arrow Direction.
Die Rippen sind mit d und die Kanäle mit g wie beim Hauptpatent, die Aussparungen mit Zz1, h2, /?3. . . . bezeichnet.The ribs are marked with d and the channels with g as in the main patent, the recesses with Zz 1 , h 2 , /? 3 . . . . designated.
Die Fig. ι zeigt eine Vereinigung der konzentrischen und spiralförmigen Rippen a! des Hauptpatentes, und zwar in der Weise, daß das eine Ende der kleinsten konzentrischen Rippe mit dem Anfang der nächst größeren konzentrischen Rippe und das Ende dieser mit dem Anfang der dritten Rippe usw. derart verbunden ist, daß eine endlöse Rippe mit den Ausschnitten h des Hauptpatentes entsprechenden Durchgängen A1, h2. . . . entsteht, welche die Vorzüge der beiden vereinigt und gegenüber den spiralförmigen Rippen des Hauptpatentes den Vorzug besitzt, daß die Zwischenräume, abgesehen von den Durchgängen Ji1, h2 usw. fast bis zu den Enden der Rippen gleich breit sind und die Beanspruchung der Siebe auf Biegung überall die gleiche ist.The Fig. Ι shows a union of the concentric and spiral ribs a! of the main patent, in such a way that one end of the smallest concentric rib with the beginning of the next larger concentric rib and the end of this with the beginning of the third rib, etc. is connected in such a way that an endless rib with the cutouts h of the Main patent corresponding rounds A 1 , h 2 . . . . arises, which combines the advantages of the two and has the advantage over the spiral ribs of the main patent that the gaps, apart from the passages Ji 1 , h 2 etc., are almost the same width up to the ends of the ribs and the strain on the sieves Bend is the same everywhere.
Die Rippen nach Fig. 2 unterscheiden sich von den konzentrischen Rippen des Hauptpatentes nur dadurch, daß dieselben statt rund viereckig (quadratisch) sind; dieselben können auch ein beliebiges Vieleck bilden.The ribs of Fig. 2 differ from the concentric ribs of the main patent only in that they are square instead of round; the same can also form any polygon.
Die eckige Form der Siebe nach den Fig. 2 und 4 besitzt gegenüber der runden den Vorzug, daß die Filter pro qm Filter- und Gehäusefläche erheblich billiger werden.The angular shape of the sieves according to FIGS. 2 and 4 has the advantage over the round ones that the filters per square meter of filter and housing area are considerably cheaper.
Die Rippen der Fig. 3 und 4 verlaufen zum größten Teil geradlinig.The ribs of FIGS. 3 and 4 are for the most part straight.
Die Zuführung und Abführung der Flüssig- 4^ keit, welche bei den Rippen des Hauptpatentes und den nach den Fig. ι und 2 in einem endlosen Strom erfolgen, erfolgen nach Fig. 3 und 4 in parallelen Strömen mit geringer Geschwindigkeit, durch welche die Reibung der Flüssigkeit vermindert wird.The supply and discharge of liquid 4 ^ ness which, when the ribs of the main patent and in FIGS ι., And carried out 2 in an endless stream, carried out according to Fig. 3 and 4 in parallel streams with low speed by which the friction the liquid is reduced.
