Description

Zellenfilter-Saugtrommel Gegenstand der vorliegenden Erfindung ist eine Zellenfilter-Saugtrommel, bei der die Ab-und Anstellung der Saugwirkung zu den einzelnen Zellen durch Hähne bzw. Ventile o. dgl. geschieht und die Hauptflüssigwkeitsabsaugung durch den Schleifkopf gesteuert wird.Cell filter suction drum is the subject of the present invention a cell filter suction drum with which the suction effect is switched off and on the individual cells through taps or valves o. The like. happens and the main liquid suction is controlled by the grinding head.

Die bisher bekannten Zellenfilter-Saugtrommeln bewerkstelligen die Ansaugung der zu filtrierenden Masse aus dem Trog, und je nachdem, welches spezifische Gewicht die Masse aufweist, richtet sich auch die Leistungsfähigkeit des Apparates, bei dem die abgesaugte Flüssigkeit bis zur Mitte der Trommel geführt werden muß. Bei der Abblasung des Kuchens von der Oberfläche der Trommel an der Schabemesserstelle wurde Druckluft verwandt; diese wurde durch die Absaugekanäle zugeführt, die die an den Wänden noch haftende Feuchtigkeit in den Kuchen zurückbliesen und das bereits getrocknete Material wieder anfeuchteten. The previously known cell filter suction drums accomplish this Suction of the mass to be filtered from the trough, and depending on which specific one Weight has the mass, the performance of the apparatus is also determined, in which the extracted liquid must be guided to the center of the drum. When the cake is blown off the surface of the drum at the scraper knife point compressed air was used; this was fed through the suction channels that the The moisture that was still adhering to the walls was blown back into the cake and that already moisten the dried material again.

Gemäß der vorliegenden Erfindung, welche diese Übelstände beseitigt, erhalten die Zellenfilter-Saugtrommeln außer den bekannten Absperrventilen oder Hähnen eine weitere Absaugungsmöglichkeit in Form eines Schleifsegmentes, welches das Filtrat in der untersten Zone des Trommelumfanges unmittelbar aus den Filterzellen abführt. Dieses Saugschleifsegment steuert zu gleicher Zeit die Saugventile. Besonders wertvoll ist die Erfindung bei den Filtern mit seitlich angebrachten Trögen. Durch diese neue Anordnung wird die Leistungsfähigkeit solcher Zellen-Saugtrockner bedeutend gesteigert. According to the present invention, which eliminates these inconveniences, receive the cell filter suction drums in addition to the well-known shut-off valves or Another suction option in the form of a grinding segment, which the filtrate in the lowest zone of the drum circumference directly from the filter cells leads away. This suction grinding segment controls the suction valves at the same time. Particularly The invention is valuable in the case of filters with side-mounted troughs. By this new arrangement makes the performance of such cellular suction dryers significant increased.

In der Zeichnung ist ein Beispiel der neuen Zellenfilter-Saugtrommel dargestellt. In the drawing is an example of the new cell filter suction drum shown.

In das Filtergut, das sich in dem Trogs bzw. b befindet, taucht die -Trommelfilterfläche c, welche aus Filtertuch, Filtersieb o. dgl. besteht, das über gelochte Bleche d gespannt ist. Die Kammern stehen unter Saugwirkung und saugen die Hauptflüssigkeit durch die Kanäle, in welche Ventiles eingebaut sind, zu dem Saugschleifsegment; außerdem stehen mit den Kanälen f radiale Kanäle in Verbindung, in die Absperrhähne k eingebaut sind, die nur an der Abnahmestelle des Kuchens geschlossen sind. An dieser Stelle ist dagegen der DrucklufXhnl geöffnet, und sämtliche übrigen Drucklufthähne 1 sind geschlossen. er Arbeitsgang ist folgender. The is immersed in the filter material that is in the trough or b -Drum filter surface c, which consists of filter cloth, filter sieve o. The like. That over perforated sheet metal d is clamped. The chambers are under suction and suck the main liquid through the channels in which valves are installed to the Suction grinding segment; in addition, there are radial channels with the channels f in connection, in which the shut-off cocks k are installed, which are only available at the tapping point of the cake are closed. At this point, however, the compressed air is open, and all other compressed air taps 1 are closed. he operation is as follows.

Wenn die Ventile g und die Hähne k bei Punktc (Abb. 7) in den Troga bzw. b eintauchen und somit auf die Rippe n (Abb. 1) des Saugschleifsegments h und die Hähne k auf den Anschlagnocken p (Abb. 2) auflaufen, so werden die Ventile g und die Hähne k bei a geöffnet, und die Absaugperiode beginnt. When the valves g and the cocks k at point c (Fig. 7) in the trough or b and thus dip onto the rib n (Fig. 1) of the suction grinding segment h and the taps k open on the stop cam p (Fig. 2), the valves g and the taps k open at a, and the suction period begins.

Die Hauptfiltratflüssigkeit tritt an der untersten Stelle der Trommel durch die Ventile in das Saugschleifsegment h ein und durch einen oder mehrere Auslaufstutzen m aus. The main filtrate liquid occurs at the lowest point of the drum through the valves into the suction grinding segment h and through one or more outlet nozzles mouse.

Bei y (Abb.. 7) verläßt nun das Ventils das Saugschleifsegment, indem es bei weiterer Drehung der Trommel von der Rippen abläuft und sich schließt, während die Hähne k durch den Anschlagnocken o wieder geschlossen werden. Die betreffende Zelle hat nun das Schabemesser q erreicht, und die Absaugperiode ist beendet. Zu gleicher Zeit, wenn die Zelle bei P (Abb. 7) angelangt ist, öffnet sich auf der anderen Seite der Trommel der Hahn 1 durch einen Anschlagnocken o' (Abb. I) in gleicher Weise, wie auf der Absaugseite (Abb.. 2 und 3) der Hahns durch den Anschlagnocken o geschlossen wird, um das Spülmittel, z. B. Druckluft, in die Zelle einzulassen. Sobald die betreffende Zelle das Schabemesser q passiert hat, schließt sich der Hahn l durch den Anschlagnocken p' (Abb. 2 und 3), und die Absaugperiode beginnt von neuem. At y (Fig. 7) the valve now leaves the suction grinding segment by as the drum continues to rotate, it runs off the ribs and closes while the taps k are closed again by the stop cam o. The person in question The cell has now reached the scraper blade q and the suction period has ended. to at the same time, when the cell has reached P (Fig. 7), opens on the other side of the drum of the tap 1 by a stop cam o '(Fig. I) in the same Way, as on the suction side (Fig. 2 and 3) the tap through the stop cam o is closed to the detergent, z. B. compressed air to let into the cell. As soon as the cell in question has passed the scraping knife q, the Tap l through the stop cam p '(Figs. 2 and 3), and the suction period begins all over again.
