Abstract

A filling apparatus for unfiltered liquid in multi-stage pressure filters, in which, to avoid the filter frame, a filling tube is clamped, on closing the filter press, by shaped pieces in recesses in the peripheral walls of the filter chambers in such a manner that the filter cavity is closed as a result in a pressure-tight manner.

Description

Beschreibung:Description:

In der Beschreibung des Hauptpat nts P ist ausführlich dargestellt, daß bei Eta@endruckfiltern auf den Filterrahmen verzichtet werden kann, wenn das Unfiltrat durch eine erfindungsgemäße Vorrichtung zugefitirt wird, die im wesentlichen aus einem Einftillrohr besteht, das von einem aus elastischem Werkstoff bestehenden Formstück umgeben ist und das beim Schließen der Filterpresse mit diesem Formstück so in Zussparunger in den Umfassungswänden der Filterkammern eingeklemmt wird, daß der Filterhohlraum dadurch wie durch einen Pfrcpf druckdicht verschlossen wird.In the description of the main patent P It is shown in detail that the filter frame can be dispensed with with Eta @ endpressure filters if the unfiltrate is fed in by a device according to the invention, which essentially consists of a filler tube that is surrounded by a molded piece made of elastic material and that when the filter press is closed is clamped with this molded piece in the recess in the surrounding walls of the filter chambers that the filter cavity is thereby closed pressure-tight as by a Pfrcpf.

Eine für bestimmte Anwendungsfälle erfindungsgemäß weitergehende Verbesserung der im Hauptpatent vorgeschlagenen Einfüllvorrichtung für Unfiltrat besteht nun darin, die Aussparungen la und 1b in den Filterkammer-Umfassungswänden 2a und 2b mit Formstücken aus elast. erkstoff 3a und 3b so auszufüttern, daß beim Schlieffen der Filterpresse das Einfüllrohr 4 druckdicht eingeklemmt wird. Abb.1 stellt den Querschnitt durch zwei Filterkammern dar, Abb.2 die entsprechende Seitenansicht. Die Lage der riltertincher ist gestrichelt wieder@egeben.A further improvement according to the invention for certain applications the filling device for unfiltrate proposed in the main patent now exists therein, the recesses la and 1b in the filter chamber enclosing walls 2a and 2b with fittings made of elast. erstoff 3a and 3b to be fed in such a way that when sleeping the filter press the filler pipe 4 is clamped pressure-tight. Fig.1 represents the Cross-section through two filter chambers, Figure 2 shows the corresponding side view. The location of the riltertincher is shown in dashed lines.

Um der elastischen Verformbarkeit der Formst@cke weitgehend entgegenzukommen, kann der Einfällrohrquersch@itt nach Abb.3 geformt sein.In order to largely accommodate the elastic deformability of the moldings, the incidence tube cross-section can be shaped as shown in Figure 3.

Die funktionelle Verbesserung der Frindung besteht darin, daß die beim Öffnen der Filterpresse sich ergebenden Abstände zwischen den Filterelementen nicht höher sein müssen, als die größte Hohe des Einfüllrohrquerschnitts, während bei den im @auptp@tent beschriebenen Vorrichtungen die Abstände zwischen den Filterelementen sich um die doppelte Dicke des das Einfüllrohr umgebende Formstück vergrößern, um letztendlich die Filtertücher zum Abwurf des Filterkuchens frei beweglich zu machen. Die im Hauptpatent beschriebenen Maßnahme@ zur Führung und Halterung des Einfüllrohrs werden durch die im Zusatspa@ert beschriebenen Verbesserungen nicht betroffen.The functional improvement of the friendship consists in the fact that the when opening the filter press resulting distances between the filter elements need not be higher than the greatest height of the filler pipe cross-section, while for the devices described in the @ auptp @ tent, the distances between the filter elements increase by twice the thickness of the fitting surrounding the filler pipe ultimately to make the filter cloths freely movable for throwing off the filter cake. The measure @ described in the main patent for guiding and holding the filler pipe are not affected by the improvements described in the supplement.
