  Filterelement

   Das nur auf seiner Oberseite 1 durchlässige, vorzugsweise scheibenförmige Filterelement besteht in bekannter Weise aus einem Filtertuch 2, einer porösen Zwischenschicht 3 und aus dem undurchlässigen Bodenblech 4. Es ist auf einer drehbaren Hohlwelle 5 angeordnet, wobei es nach oben und unten durch je einenDistanzring 6 in Abstand von den benachbarten Filterelementen gehalten wird. In dem oberhalb des Filterelementes befindlichen Distanzring 6 sind eine Anzahl, beispielsweise sechs-   radial verlaufender Stäbe   7,   Drähte od. dgl. vorzugsweise durch Einschrauben befestigt. An ihren freien   Enden sind sie mit einem Gewinde 8 versehen. Über dieses ist eine Halteklaue 9 geschoben, die mittels einer Mutter 10 gegen den Rand der Filterscheibe festspannbar ist.

   Damit werden die Stäbe 7 gespannt und gleichzeitig auch das Filtertuch 2 festgehalten und angezogen. Weiterhin stützen die Halteklauen 9 das Bodenblech 4 ab. Dadurch ist es möglich, das letztere bedeutend dünner zu halten, ohne dass die Festigkeit der Filterplatte darunter leidet. 



   Die Stäbe 4 haben den weiteren Vorzug, dass beim Rückspülen das Filtertuch keine besondere Ausbeulung erhält. Beim Abschleudern der Rückstände von den Filterelementen mittels Zentrifugalkraft wird das Gewebe weniger beansprucht, weil es festgehalten ist. Es zerreisst nicht. 



   Auf das Gewinde 8 bzw. mit seiner Hilfe, können an den Rändern der Elemente gegebenenfalls Kratzbleche, Austragsschnecken usw. befestigt werden.

  Filter element
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   The preferably disc-shaped filter element, which is only permeable on its upper side 1, consists in a known manner of a filter cloth 2, a porous intermediate layer 3 and of the impermeable base plate 4. It is arranged on a rotatable hollow shaft 5, with a spacer ring 6 up and down each is kept at a distance from the neighboring filter elements. In the spacer ring 6 located above the filter element, a number of, for example, six-radial rods 7, wires or the like are fastened, preferably by screwing in. They are provided with a thread 8 at their free ends. A retaining claw 9, which can be tightened against the edge of the filter disk by means of a nut 10, is pushed over this.

   The rods 7 are thus tensioned and at the same time the filter cloth 2 is also held and tightened. Furthermore, the holding claws 9 support the floor panel 4. This makes it possible to keep the latter significantly thinner without the strength of the filter plate suffering.



   The rods 4 have the further advantage that the filter cloth does not have any particular bulge during backwashing. When the residues are thrown off the filter elements by centrifugal force, the fabric is less stressed because it is retained. It doesn't tear.



   Scraper plates, discharge screws, etc. can optionally be attached to the thread 8 or with its help on the edges of the elements.
