Description

Vorrichtung zur Abnahme des Filterkuchens von Zellendrehfiltern Zusatz zum Patent 671 703 Gegenstand des Hauptpatents 67I 703 ist eine Vorrichtung zur Abnahme des Filterkuchens von Zellendrehfiltern, bei welcher der Filterkuchen durch eine Walze mit rauher Oberfläche, die dauernd mit einer Filterkuchenschicht bedeckt ist, vom Drelifilter abgenommen und durch eine Gegenwalze von der Abnahmewalze abgequetscht wird. Bei sehr steifen Kuchen kann es vorkommen, daß beim Abquetschen sich Zwängungen zwischen den beiden Walzen ergeben.Device for removing the filter cake from rotary cell filters to the patent 671 703 Subject of the main patent 67I 703 is a device for Removal of the filter cake from rotary cell filters, in which the filter cake passes through a roller with a rough surface that is permanently covered with a layer of filter cake is, removed from the Drelifilter and squeezed off from the take-off roller by a counter roller will. In the case of very stiff cakes, it can happen that they are squeezed out between the two rollers.

Erfindungsgemäß wird daher vorgeschlagen, in diesen Fällen die Gegenwalze derartig auszubilden, daß mehrere in Abständen auf der Drehachse angeordnete Scheiben vorgesehen sind, über deren Ränder parallel zu der Drehachse eine Anzahl Schneidedrähte gespannt sind. Bei der Drehung dieser käfigartigen Gegenwalze werden stoßweise kleine Kuchenmengen von der Abnahmewalze abgeschlagen, ohne daß Kuchen an den Drähten haftenbleibt. Drehrichtung, Drehzahl und Durchmesser dieser Walze richten sich nach der Steifigkeit und anderen Bedingungen der von der Abnahmewalze abzuhebenden Kuchenschicht. According to the invention it is therefore proposed to use the counter roll in these cases in such a way that a plurality of disks arranged at intervals on the axis of rotation are provided, over the edges of which a number of cutting wires parallel to the axis of rotation are excited. When this cage-like counter-roller rotates, intermittently small ones Pieces of cake are knocked off the take-off roller without cake sticking to the wires. The direction of rotation, speed and diameter of this roller depend on the rigidity and other conditions of the cake layer to be lifted from the take-off roller.

Die Abb. I und 2 der Zeichnung zeigen eine Ausführungsform der Gegenwalze im Schnitt und in Draufsicht. Von der Filtertrommel a wird der Kuchen d durch die Abnahmewalie b in den Bereich der Gegenwalze gefördert. Die Gegenwalze besteht aus den auf der Achse c befestigten Scheiben e, über deren Ränder die Schneidedrähte f gespannt sind, die in die Kuchenschicht d einschlagen und sie abschlagen und fortschleudern. Figs. I and 2 of the drawing show an embodiment of the counter roll in section and in plan view. From the filter drum a the cake d is through the Abnahmewalie b promoted in the area of the counter roll. The counter roll consists of the disks e attached to the axis c, over the edges of which the cutting wires f are tense, which hit the cake layer d and knock it off and throw it away.
