Description

Die Erfindung betrifft eine Membranplatte aus Gummi oder gummiähnlichem, d. h. aus elastomerem Werkstoff, die an der Oberseite der Oberschicht Noppen aufweist, zur Trennung von Fest-Flüssigkeit-Gemischen. Dabei besteht das gesamte Membranfilterpressen-System aus folgenden Einzelteilen:The invention relates to a membrane plate made of rubber or rubber-like, d. H. out elastomeric material with knobs on the top of the top layer for separation solid-liquid mixtures. The entire membrane filter press system consists of following parts:

  • - Kammerplatte;- chamber plate;
  • - Membranplatte;- membrane plate;
  • - Rahmen.- Frame.

Die mit Noppen versehene Oberseite der Oberschicht nennt man auch Filterseite, da die Oberschicht als Auflage für die Filtermembran dient.The pimpled top of the top layer is also called the filter side, because the The upper layer serves as a support for the filter membrane.

Als Druckmittel können Gase verwendet werden. Ein niedriger Filterdruck und ein höherer Nachpreßdruck bringen besonders gute Ergebnisse.Gases can be used as pressure medium. A lower filter pressure and a higher one Reprint pressure bring particularly good results.

Aus der WO 90/06797 ist eine Membranplatte bekannt, die aus einer Kernschicht aus Kunststoff, insbesondere aus einem Schaumkunststoff oder einem mit Füllstoffen versehenen Kunststoff, besteht, die wiederum von einer außen liegenden Verstärkungseinlagenschicht und einer zusätzlichen Außenschicht aus thermoplastischem Kunststoffmaterial umgeben ist.From WO 90/06797 a membrane plate is known which consists of a core layer made of plastic, in particular from a foam plastic or a plastic provided with fillers, consists, in turn, of an outer reinforcing insert layer and one additional outer layer of thermoplastic material is surrounded.

Trotz vielfältiger Vorteile der bekannten Systeme gibt es bislang das Problem, daß Membranplatten aus Gummi oder gummiähnlichem Kunststoff unter den Betriebsbedingungen verschleißanfällig sind.Despite the many advantages of the known systems, there is the problem that Membrane plates made of rubber or rubber-like plastic under the operating conditions are prone to wear.

Gelöst wird nun dieses Problem dadurch, daß die Membranplatte einen Festigkeitsträger aufweist.This problem is now solved in that the membrane plate has a reinforcement having.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 8 genannt.Advantageous embodiments of the invention are mentioned in claims 2 to 8.

Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Bezugnahme auf eine schematische Zeichnung dargestellt. Dabei weist die Membranplatte (1) folgenden Aufbau auf:The invention will now be illustrated using an exemplary embodiment with reference to a schematic drawing. The membrane plate ( 1 ) has the following structure:

  • - Oberschicht (2) mit Noppen (3) aus Gummi oder gummiähnlichem Kunststoff;- Upper layer ( 2 ) with knobs ( 3 ) made of rubber or rubber-like plastic;
  • - Festigkeitsträger (4) als Gewebe, insbesondere PA-Gewebe;- Strength members ( 4 ) as a fabric, in particular PA fabric;
  • - Unterschicht (5) aus Gummi oder gummiähnlichem Kunststoff.- Lower layer ( 5 ) made of rubber or rubber-like plastic.
