Description
Endlose Schnurbespannung für Trommelfilter Es sind kontinuierliche Trommelfilter bekannt, die den Filterkuchen durch ein umlaufendes Schnürenband von der Trommel abnehmen und entweder über eine Trockenanlage oder direkt zu einem kammartigen Kratzer bringen, der das Abfallen des Gutes veranlaßt. Diese Schnürenbänder bestehen aus einer großen Anzahl einzelner paralleler Schnüre, die in geeignetem Abstand um die Filtertrommel, die Umleitrollen und Trockentrommel gelegt und einzeln verknlipft werden.Endless cord covering for drum filters They are continuous Drum filter known that the filter cake by a rotating cord of remove the drum and either through a drying system or directly to a comb-like Bring scratches that cause the item to fall off. These cords are made from a large number of individual parallel cords, appropriately spaced placed around the filter drum, the guide rollers and the drying drum and individually linked will.
Diese Ausführung hat den Nachteil, daß einmal die zahlreichen Knoten die Entstehung eines Filtergutfilms stören, dann aber auch vor allem die Spannung in den einzelnen Schnüren sehr scher gleichmäßig zu halten ist. Die ungleichmäßige Spannung stört aüdl ihrerseits den einwandfreien Filtervorgang beträchtlich.This design has the disadvantage that once the numerous nodes interfere with the formation of a film of filter material, but then above all with the tension must be kept very evenly in the individual cords. The uneven For its part, voltage disturbs the proper filtering process considerably.
Es wurde nun gefunden, daß man diese Nachteile dadurch vermeiden kann, daß man statt der zahlreichen Einzelschnüre eine einzige Schnur verwendet, die schraubenartig mehrfach über die Trommeln und Rollen gewickelt wird. Das auf und ab laufende Ende der Schnur wird dann, wie es bei ähnlichen Schnurführungen bereits bekannt ist, über mindestens zwei Führungsrollen quer verbunden; zweckmäßig sind dabei die Achsen der Trommeln oder Rollen leicht gekreuzt. It has now been found that these disadvantages can be avoided in this way it is possible to use a single cord instead of the numerous individual cords, which is wound several times over the drums and rollers like a screw. That on and from the running end of the cord, as is the case with similar cord guides is already known, connected across at least two guide rollers; expedient the axes of the drums or rollers are slightly crossed.
Diese Anordnung bewirkt zunächst eine absolut gleichmäßige Spannung aller Schnüre unter gleichzeitigem Wegfall der vielen Verknotungen. Eine der Führungsrollen kann automatisch durch Gewichte oder Federn oder von Hand verstellbar angeordnet sein, um die Höhe der gleichmäßigen Spannung konstant zu halten oder aber vorschriftsmäßig auf einfache ÄVeise zu verändern. Da die Schnur immer in sich selbst zurückkehrt, ist ein Abwandern unmöglich. Das Auswechseln der Bespannung zum Zwecke der Reparatur oder des Überganges auf eine andere Schnurart ist sehr einfach. Man braucht nur die alte Schnur etwa bei einer der Führungsrollen abzuschneiden und mit dem einen Ende der neuen Schnur zu verknüpfen und dann in den Apparat einlaufen zu lassen.This arrangement initially creates an absolutely even tension of all cords while eliminating the many knots. One of the leadership roles can be arranged to be adjustable automatically by weights or springs or by hand in order to keep the level of the uniform tension constant or in accordance with regulations easy to change. As the cord always returns to itself, migration is impossible. Replacing the covering for the purpose of repairs or the transition to another type of cord is very easy. You just need cut off the old cord at one of the guide rollers and with one To tie the end of the new cord and then let it run into the apparatus.
Zwischen den Führungsrollen A und B kann man einen Schützwächter anbringen, der bei einem Nachlassen der Spannung automatisch die Anlage stillsetzt. A contactor monitor can be placed between the guide rollers A and B. which automatically shuts down the system when the voltage drops.
Wenn es die bauliche Anordnung erlaubt, wird man die Umleitungsrollen A und B zweckmäßig auf dem vom Filtergut befreiten Teil der Bespannung anbringen. If the structural arrangement allows it, one will use the diversion roles Appropriately attach A and B to the part of the covering that has been freed from the filter material.
Auf beiliegender Zeichnung ist die Führung der endlosen Schnur über zwei Trommeln schematisch dargestellt. On the accompanying drawing, the guide of the endless cord is over two drums shown schematically.
Die endlose Schnur S ist über die Fiihrungsrollen A und B und dann in mehreren Windungen schraubenartig über die Trommeln 1 und 11 gefübrt. The endless cord S is over the guide pulleys A and B and then gefübrt helically over drums 1 and 11 in several turns.
