Description

Drehbare Filtersaugtrommel mit über die Trogwände hinaus verlängerten Lagerhälsen.Rotatable filter suction drum with extended over the trough walls Bearing necks.

Bei den bekannten Filtersaugtrommeln, bei ei welchen der nicht wirksame Teil durch eine am inneren Umfang derselben starr anliegende sektor- oder segmentförmige Platte abgedichtet wird, entsteht entweder eine starke Bremswirkung oder bei ungenügender Auflage der Sektor- oder Segmentplatte der Übelstand, daß große Mengen unwirksamer Luft abgesaugt werden müssen. Beide Fälle bedingen einen großen Aufwand an Kraft. In the known filter suction drums, in which the ineffective Part by a sector-shaped or segment-shaped body that rests rigidly on the inner circumference of the same Plate is sealed, there is either a strong braking effect or inadequate Edition of the sector or segment plate the disadvantage that large amounts are ineffective Air must be extracted. Both cases require a great deal of force.

Diese Übelstände werden durch vorliegende Erfindung nun dadurch beseitigt, daß ein in bekannter Weise an der inneren Trommelfläche angeordnetes Abdichtungsorgan, welches den nicht von dem endlosen Filtertuch umspannten Teil der Trommel abdeckt, außen nachgiebig gelagert ist, um ein genaues Einstellen während des Betriebes nach Bedarf zu ermöglichen und jede Reibung zu verhindern. These deficiencies are now eliminated by the present invention by that an in in a known manner arranged on the inner drum surface Sealing member, which is the part not encompassed by the endless filter cloth the drum covers, is externally resilient to allow precise adjustment during to enable operation as required and to prevent any friction.

Auf der Zeichnung ist eine beispielsweise Ausführung dargestellt. Es zeigen Abb. I einen Längsschnitt, Abb. 2 einen Querschnitt und Abb. 3 eine Stirnansicht der Filtertrommel. An example of an embodiment is shown in the drawing. Fig. I shows a longitudinal section, Fig. 2 shows a cross section and Fig. 3 shows a front view the filter drum.

In dem Trog ist die Filtertrommel a drehbar gelagert und von einem endlosen Filterband b umhüllt. Der von dem Filterband b nicht umspannte und daher nicht wirksame Teil der Trommel wird von einem im Innern der Trommel angeordneten und gegen die innere Trommelfläche anliegenden Ab dichtungsorgan c, welches ringsum mit Dihtungsleisten versehen ist, verschlossen. Das Abdichtungsorgan ist zwecks genauen Einstellens an den äußeren Stirnwänden bei e in nachgiebigen Manschetten abgedichtet und außen bei d nachgiebig gelagert, um jede Reibung zu verhindern. Die Lagerung d besteht aus einer Gleitführung mit gebäuseartig ausgebildetem Kopf f, in welchen eine Spiralfeder oder ein Gummipuffer eingesetzt ist. In the trough, the filter drum is rotatably mounted and a endless filter belt b wrapped. The one not spanned by the filter band b and therefore ineffective part of the drum is arranged by an inside the drum and against the inner drum surface abutting from sealing member c, which all around is provided with sealing strips, closed. The sealing element is for the purpose Precise adjustment on the outer end walls at e in flexible cuffs sealed and resiliently supported on the outside at d to prevent any friction. The bearing d consists of a sliding guide with a head designed in the manner of a building f, in which a spiral spring or a rubber buffer is inserted.

An der äußeren Wand des Troges befindet sich im unteren Teil ein Ab 3ußstutzen, welcher mit einer Saugpumpe in Verbindung 1 steht, während im oberen Teil ein Stutzen zum Anschluß an eine Saugluftpumpe angebracht ist. On the outer wall of the trough there is a in the lower part From 3ußstutzen, which is connected to a suction pump 1, while in the upper Part of a nozzle for connection to a suction air pump is attached.

Bei der Inbetriebsetzung wird die Trommel unter Unterdruck gesetzt, wobei die Flüssigkeit durch das Filterband tritt, während sich die festen Stoffe als Filterschicht auf dem Filterband absetzen. When starting up, the drum is placed under negative pressure, whereby the liquid passes through the filter belt while the solids move Set as a filter layer on the filter belt.

Der von dem Filterband nicht umspannte und nicht wirksame Teil der Trommel wird durch das Abdichtungsorgan c, welches von außen genau und nachgiebig einstellbar ist, verschlossen. The part of the not spanned and ineffective by the filter belt Drum is through the sealing member c, which is accurate and flexible from the outside is adjustable, closed.

Die sich auf dem Filterband b bildende Schicht erfährt nach dem Heraustreten aus der Flüssigkeit infolge der im Trommelinnern herrschenden Luftverdünnung eine sofortige Entwässerung und wird von dem Filterband b weiter getragen, um in bekannter Weise zwecks weiterer Behandlung einer Walzenpresse zugeführt zu werden. The layer forming on the filter belt b experiences after stepping out from the liquid as a result of the air dilution prevailing inside the drum immediate drainage and is carried by the filter belt b further to known in Way to be fed to a roller press for further treatment.
