Description

Die Erfindung betrifft ein poröses Rohr aus Faservliesmaterial, dessen lnnerdeite mit einer Membran zur Membranfiltration versehen oder für deren Anbringung vorgesehen ist. J<>
Rohre dieser Art mit innenseitig aufgebrachter Membran sind während Filtrationsvorgängen in Stützrohren angeordnet, die dem hohen Druck standhalten, unter dem die zu revnigeno'·. Flüssigkeit in das Rohrinnere eingeleitet wird. Dieser hohe Innendruck preßt das Rohr an die Innenwand^ j des Stützrohres an und bereichsweise auch in öffnungen im Stützrohr hinein, die zur Ableitung des Permcats vorgesehen sind. Dadurch ergibt sich ein starkes Haften des Rohres im Stützrohr, so daß es schwierig ist, für einen Membran- ■"' wechsel das Rohr aus dem Sliitzrohr zu entfernen. In der Praxis erfolgt ein derartiges Entfernen in einem zeitraubenden Vorgang durch Gewaltanwendung und unter Zerstörung des Rohres.
Der Erfindung liegt die Aufgabe zugrunde, ein Rohr 41» der eingangs genannten Art zu schaffen, das bei einfacher Ausbildung schnell und leicht aus dem Stützrohr entfernt werden kann, wenn seine Membran verbraucht ist. Hierzu ist das Rohr nach der Erfindung dadurch gekennzeichnet, daß r>o
a) das poröse Rohr mit einem Aufreißglied versehen ist, das einen hakenförmigen Teil zum Aufreißen des Rohres aufweist, der über einen Faden mit einem Zugring verbunden ist oder ,.,.
b) als Aufreißglied eine Längsschweißnaht vorgesehen ist, die durch Ultraschallschweißen bei einander überlappenden oder aneinanderstoßenden Randzonen gebildet ist. Bei dem porösen Rohr nach a) kann das Aufreißglied zwischen zwei W) benachbarten Lagen des Faservliesmaterials des Rohres eingebettet sein.
Mit Hilfe eines derartigen Aufreißgliedes kann das Pohr schnell und leicht von einem Ende her /um anderen Ende hin aufgerissen und anschließend mühelos hr' aus seinem Stützrohr herausgezogen werden. Dies gilt sowohl für die Ausgestaltung nach a), bei der der hakenförmige Teil durch das Faservliesmaterini auftrennend hindurch bewegt wird, als auch for die besonders herstellungsgünstige Ausgestaltung nach b), bei der die durch Ultraschallschweißen gebildete Längsschweißnaht einen sehr schmal ausführbaren und präzise begrenzten Stre'ifenbereich hoher Verfestigung bildet, der in einer Schälbewegung als Ganzes ausreißbar ist
Aus der CH-PS 5 00 744 ist zwar als Träger für eine Membran zur Membranfiltration bereits ein biegsamer Schlauch aus einem porösen Faservliesbend bekannt, dessen Ränder zur Bildung einer längsverli-oifenden Schlauchnaht aneinanderstoßend oder sich gegenseitig überlappend miteinander verschweißt sein können. Die Längsschweißnaht dient jedoch nur der Randverbindung und ist nicht durch Ultraschallschweißen gebildet Ein Aufreißglied ist bei einem biegsamen Schlauch als Träger für die Membran weder erforderlich noch sinnvoll, da es wegen der Nachgiebigkeit der Schlauchnaht aus dieser auch nicht separat ausreißbar ist
Bei einem porösen Rohr der eingangs genannten Art das durch schraubenlinienförmiges Aufwickeln eines Faservliesbandes und Verschweißen aneinanderstoßender oder einander überlappender Randbereiche gebildet ist ist es weiterhin bekannt, die schraubenlinienförmige Schweißnaht durch Ultraschallschweißen zu erzeugen. Auch hier bildet die Schweißnaht jedoch lediglich eine Verbindungsnaht und wegen des schraubenlinienförmigen Verlaufes der Schweißnaht in der Rohrwandung ist sie auch als Autreißglied nicht verwendbar, da nur ein für ein Aufreißen nicht ausreichender Bruchteil einer längs des Rohres gerichteten Zugkraft als Aufreißkraft in die Schweißnaht eintragbar isv.
Nachstehend werden mehrere Ausführungsbeispiele in Verbindung mit der Zeichnung näher erläutert. In der Zeichnung zeigt
Fig. I einen schematischen Längsschnitt durch eine erste Ausführung eines Rohres nach der Erfindung,
F i g. 2 einen Längsschnitt durch eine zweite Rohrausführung,
Fig.3 einen schematischen Querschnitt durch eine dritte Rohrausführung,
Fig.4 eine perspektivische Ansicht eines Rohres nach F i g. 3,
Fig.5 eine Vorrichtung zur Herstellung eines erfindungsgemäßen Rohres,
Fig.6 und 7 Einzelheiten betreffend die Herstellung von Längsschweißnähten.
Fig. I zeigt ein poröses Rohr f aus einem Faservlies aus Polyesterfasern, an dessen Innenseite eine Zelluloseazetat-Membran 2 befestigt ist. Diese Anordnung ist in einem Stützrohr 3 aus thermoplastischem Material mit Öffnungen 4 untergebracht, durch die das Pcrmeat, das durch die Membran hindurchgegangen ist, abgeführt wird.
Das Rohr i ist mit einem Aufreißglied 5 verschen, das bei der Ausführung nach Fig. I einen hakenförmigen Teil 6 zum Aufreißen des Rohres I aufweist, der über einen Faden 7 mit einem Zugring 8 verbunden ist.
Bei der Ausführung nach Fig.2 besteht das Rohr 1 aus zwei Faservliesschichten la und \b, z. B. aus Polyesterfaserpapier, zwischen denen das Aufreißglied 5gemäß Fig. 1 eingebeitel ist.
F i g. 3 zeigt eine Ausführung mit einem Faservlies aus Polyester, bei der das Aufreißglied 5 aus einer durch Ultraschallschweißen gebildeten Längsschweißnaht des Rohres I besteht. Dieses Aufreißglied 5 kann sowohl bei einem Rohr aus einschichtigem Faservlies als auch bei einem solchen mit zwei Schichten I a und \b vorgesehen
ein. Fig,4 zeigt das Rohr I nach Fig.3 in erspektiviseher Ansicht.
Fig,5 veranschaulicht eine Vorrichtung beim Herlellen eines Rohres 1 mit einer Längsschweißnaht urch Ultraschallschweißen. Diese, nicht Gegenstand er Erfindung bildende Vorrichtung umfaßt eine OrratsroIIe 15 für eine Faservliesbahn 18, die über eine abstützung 16 mit Klemmstücken 17 zu einem tationären hohlen zylindrischen Dorn 19 gefördert und η diesen von Führungsorganen 9 angedrückt wird, iber dem Dorn 19 ist ein Ultraschallschweißorgan 10, Oa, 106 vorgesehen, mit dem die das Aufreißglied 5 bildende Ungsscbweißnaht bei überlappenden (F i g. 6) oder voreinanderstoßenden (F i g, 7) Randzonen 5a, 5b der Faservliesbahn 18 während deren Förderung über den Dorn 13 erzeugt wird.
Zur Förderung des Rohres 1 sind Förderorgane U, z. B. Gummibänder, vorgesehen. Zur Membranbildung kann ein eine flüssige Membranmasse, z. B. Zelluloseazetat, enthaltender Behälter 12 vorgesehen sein, dessen Auslaßleitung 13 in das Rohr 1 einmündet. Um die
IU richtige Dicke der Rohrmembran zu erhalten, ist ein torpedoförmiger Körper 14 im Inneren des Rohres 1 gehalten.
