Description

Filtertrommel in Leidhtbauweise Da sich die kontinuierliche Filtration auf Drehfiltern immer mehr durchsetzt und nun auch in Prozessen angewendet werden soll, die man bisher mit Rücksicht auf Korrosionen und damit verbundenem hohen Aufwand an beständigen Baustoffen diskontinuierlich betrieb, ist man an der Einsparung der teuren korrosionssicheren Baustoffe im Filterbau immer mehr interessiert geworden. Die meist angewendeten Trommeldrehfilter bestehen normalerweise aus einer Achse, auf der Stützringe und Stirnseiten der Trommel befestigt sind. Der Trommelmantel wird durch Schrauben oder durch Schweißen mit diesen Elementen verbunden. Um die Schwierigkeiten zu vermeiden, die das Lösen der Schrauben nach längerer Betriebszeit der Trommel mit sich bringt, ist auch vorgeschlagen worden, auf das Schrauben oder Schweißen zu verzichten und den Trommelmantel aufzuschrumpfen. Zur Abführung der Filtrate ist der - Trommelmantel gelocht. Die Löcher münden entweder direkt oder unter Zwischenschaltung eines darunterliegenden Kanals in Rohrleitungen oder die Flüssigkeit tritt in das Innere des Trommelmantels ein. Diese bisher bekannten Bauarten erfordern aber verhältnismäßig teures korrosionsfestes Material, da der Trommelmantel fest sein muß, um Drücken beim Abpressen des Filterkuchens zu widerstehen.Filter drum in Leidht construction As the continuous filtration are being used more and more on rotary filters and are now also being used in processes which has so far been done with consideration for corrosion and the associated high effort discontinuous operation of permanent building materials, one is in the process of saving the expensive corrosion-resistant building materials have become more and more interested in filter construction. The most commonly used rotary drum filters usually consist of an axis, are attached to the support rings and end faces of the drum. The drum jacket is connected to these elements by screws or by welding. To the To avoid difficulties in loosening the screws after a long period of operation the drum entails has also been suggested on the screwing or To do without welding and to shrink the drum shell on. To discharge the Filtrate is the - drum shell perforated. The holes open either directly or with the interposition of an underlying channel in pipelines or the Liquid enters the interior of the drum shell. These previously known types but require relatively expensive corrosion-resistant material, as the drum shell must be firm to withstand pressure when squeezing the filter cake.

Die nachstehend geschilderte Erfindung befaßt sich mit dem Aufbau einer Filtertrommel, die sowohl die Einsparung von Baumaterial als auch von Arbeitsstunden bei der Herstellung erlaubt. Die Erfindung ist in Abb. 1 als perspektivische Darstellung, in Abb. 2 als Teilquerschnitt gezeigt. The invention described below deals with the structure a filter drum that saves both building material and man-hours Allowed in manufacture. The invention is shown in Fig. 1 as a perspective view, shown in Fig. 2 as a partial cross-section.

Erfindungsgemäß wird vorgeschlagen, einzelne Lamellen 1 in Kerben in den Ringen 2 einzulegen und sie mit den Ringen zu verschweißen. Durch Diagonalstreben 3, die ebenfalls mit den Ringen und den I,amellen verschweißt werden, wird eine Versteifung der Konstruktion erreicht. In die Zwischenräume zwischen den Längslamellen werden die Formstücke 4, die den Zellenboden bilden, eingelegt. Zu diesem Zweck sind die Lamellen mit der Auflagefläche 5 versehen. Diese Bodenformstücke enthalten die Filtratabführungsöffnungen 7. Von ihnen führen Filtratabführungsrohre 8 zu dem Sammelkanal 9, der das Filtrat zum üblichen Steuerorgan führt. Über den Bodenformstücken ist der Rost 10 angebracht, der als Auflage für das Unterlaggewebe und das Filtermedium dient. Für die Befestigung dieser Teile enthalten die Lamellen die Nut 11. According to the invention it is proposed that individual slats 1 in notches to insert in the rings 2 and weld them to the rings. By diagonal struts 3, which are also welded to the rings and the amels, becomes a Stiffening of the construction achieved. In the spaces between the longitudinal slats the fittings 4, which form the cell floor. To this end are the slats are provided with the support surface 5. These floor fittings contain the Filtrate discharge openings 7. Filtrate discharge pipes 8 lead from them to the collecting channel 9, which leads the filtrate to the usual control unit. Above the floor fittings is the grate 10 attached, as a support for the backing fabric and the filter medium serves. The lamellas contain the groove 11 for fastening these parts.

PATENTÄNSPRUCH: Filtertrommel mit achsparallelen Zellen und an deren Böden befindlichen Abläufen, dadurch gekennzeichnet, daß das Trommelgerüst aus Ringen (2), in diesen befestigten Längslamellen (1) und diagonal in den von den Ringen und den Lamellen gebildeten Räumen verlaufenden Streben (3) besteht und zwischen den- Längslamellen Bodenformstücke (6) mit Filtratabführungsöffnungen (8) angeordnet sind. PATENT CLAIM: Filter drum with axially parallel cells and others Bottoms located drains, characterized in that the drum frame consists of rings (2), in these fixed longitudinal slats (1) and diagonally in those of the rings and the lamellas formed spaces extending struts (3) and between the longitudinal lamellae shaped floor pieces (6) with filtrate discharge openings (8) are.
