Abstract

The liner, especially for collapsible prefabricated tanks, consists of several layers which are welded or stitched into quilt sections filled with a soft voluminous material such as polyurethane foam. The seams on the various layers are staggered to maintain the sealing qualities of the liner even if it were to become damaged at separate points.

Description

Tank mit Innenauskleidung aus lose eingelegter Folie Es ist bekannt, stationäre Tanks mit einer meist sackartig ausgebildeten Folie auszukleiden, als Korrosionsschutz oder auch, um an sich undichte Konstruktionen abzudichten, wie z.B. zerlegbare M-ontage-Tanks, deren Wand aus einzelnen, miteinander verbundenen Sektionen besteht und die vom Füllungsdruck herrührenden Ringkräfte aufnimmt, an sich aber nicht dicht ist. Bei Tanks kommt es aber im Regelfall auf große Dichtheit an. Die Erfindung hat zum Ziel, die Dichtheit auch dann zu gewährleisten, wenn die Auskleidung an einzelnen Stellen beschädigt ist.Tank with inner lining made of loosely inserted film It is known Line stationary tanks with a mostly bag-like film than Corrosion protection or to seal structures that are not tight, such as E.g. dismountable assembly tanks, the wall of which consists of individual, interconnected There are sections and absorbs the ring forces resulting from the filling pressure but is not tight. In the case of tanks, however, there is usually a great deal of leakage at. The aim of the invention is to ensure the tightness even when the Lining is damaged in individual places.

Das wird erfindungsgemäß dadurch erreicht, daß die Innenauskleidung aus mehreren Lagen besteht. Die einzelnen Lagen können durch Nähte so miteinander verschweißt bzw. versteppt Bein, daß die Flächen zwischen den nähten in sich geschlossene Felder bilden. Zwischen die einzelnen Lagen kann aber auch eine Schicht as weichem, voluminösem Material, z.B.This is achieved according to the invention in that the inner lining consists of several layers. The individual layers can be joined by seams welded or quilted leg that the surfaces between the seams are self-contained Form fields. A layer of soft, bulky material, e.g.

Urethan-Schaumst off eingebracht sein.Urethane foam be introduced.

Fig. 1 zeigt eine Ausführung mit zwei Lagen, die durch Nähte 1 verbunden sind, die in sich geschlossene Felder 2 ergeben. Bei der Ausführung nach Fig.2 sind drei Lagen vorgesehen, deren Nähte 1 gegeneinander versetzt sind, so daß auch bei einer Verletzung von zwei der insgesamt drei Folien an einer Stelle kein Durchbruch durch die Folienpacklage entsteht.1 shows an embodiment with two layers connected by seams 1 which result in self-contained fields 2. In the version according to Fig.2 are three layers are provided, the seams 1 of which are offset from one another, so that even with an injury of two of the three foils at one point does not result in a breakthrough is created by the film packing layer.

Figo 3 und 4 zeigen Ausführungsbeispiele, bei denen Urethan-Schaum 6 zwischen die Folien eingebracht isto Die Folien 5 der Ausführung nach Fig. 3 sind miteinander versteppt, die Folien 3 nach Figo 4 nichts Die Sicherheit bei Beschädigungen wird auch erhöht, wenn die miteinander versteppten Folien auf ihrer Außenseite, d.h. auf ihrer der Tankwand oder dem noden zugekehrten Seite gemäß Fig. 5 mit einer Schicht 9 aus weichem, voluminösem Material versehen sind.Figo 3 and 4 show embodiments in which urethane foam 6 is inserted between the foils. The foils 5 of the embodiment according to FIG. 3 are quilted together, the foils 3 according to FIG. 4 nothing. The security in the event of damage is also increased when the quilted foils on their outside, i.e. on its side facing the tank wall or the node according to FIG. 5 with a Layer 9 made of soft, voluminous material are provided.
