man weiter, daß der an der Innenseite des Behältermantels 3
anliegende Schenkel 10 des Kragens breiter ist als der an
der Außenseite des Behältermantels anliegende Abschnitt des
Kragens 8. Der Behältermantel 3 ist mit dem behälterinnenseitigen
Schenkel 10 punktförmig durch formschlüssige,
durchdringungsfreie Verformungen 11 des Stahlblechs verbunden.
Die Verbindungen sind entweder ohne oder mit
Hilfsniet, der aber die Bleche nicht durchdringt (Toxen;
Stanznieten) herstellbar. Der den Behältermantel 3
außenseitig überfassende Rand des Behälterdeckels ist zum
Behältermantel als Bördelrand 12 umgelegt. Auf diese Weise
ist die Dichtmasse 9 von der Außenseite her weitgehend
geschützt. Die Bördelung 12 dient auch der Vermeidung von
Verletzungen.2 shows that the
Das U-förmige Mantelblech 4 und die Stirnbleche 5 sind an
ihren Längskanten durch Bördelung 13 miteinander verbunden,
wobei in die Bördelverbindung eine Dichtung eingelegt ist,
die sich bis zur Oberkante des Behältermantels 3 erstreckt.
Im Anschlußbereich des Behälterdeckels 6 liegen die
Bördelkanten flach an dem Behältermantel 3 an und fassen in
den Kragen 8 des Behälterdeckels 6 ein.The
Auf den Gewindestutzen 7 des Innenbehälters 1 sind
Druckringe 14 angeordnet, die den Behälterdeckel 6 gegen
Dichtungen 15 drücken, die zwischen dem Behälterdeckel 6
und dem Innenbehälter 1 angeordnet sind und die Stutzen 7
ringförmig umgeben. Are on the threaded connector 7 of the
Der Mantelraum zwischen Innenbehälter 1 und Außenbehälter 2
ist flüssigkeitsdicht und weitgehend gasdicht gekapselt.
Dadurch ist sichergestellt, daß auch bei kritischen
Aufstellbedingungen im Falle einer Leckage des Innenbehälters
1 keine Lagerflüssigkeit in die Umwelt gelangen
kann. Die erfindungsgemäße Kapselung des Mantelraumes
verhindert auch gasförmige Emissionen von organischen
Stoffen, die durch Diffusion durch den dünnwandigen
Innenbehälter 1 in den Mantelraum gelangen. Damit ist auch
das Problem beseitigt, daß bei der Lagerung von organischen
Flüssigkeiten in Kunststoffbehältern Geruchsbelästigungen
durch nach außen durch die Behälterwand diffundierende
Komponenten auftreten können.The jacket space between
An den Mantelraum zwischen dem Innenbehälter 1 und dem
Außenbehälter 2 ist eine Einrichtung zur Leckageüberwachung
angeschlossen, die eine mit einer Vakuumpumpe verbundene
und in den unteren Bereich des Mantelraums geführte
Saugleitung 16 sowie eine Meßleitung 17 zur Druckmessung
aufweist. Der Meßstutzen 18, durch den die Meßleitung 17
sowie die Saugleitung 16 geführt sind, ist mit einer
Dichtungsmanschette 19 gegen den Behälterdeckel 6
abgedichtet (Fig. 4). Da der Durchmesser des Meßstutzens 18
verhältnismäßig klein ist, sind aufwendigere Dichtungsmaßnahmen,
wie in der Fig. 3 dargestellt, im allgemeinen
nicht erforderlich. Im Mantelraum zwischen dem Innenbehälter
1 und dem Außenbehälter 2 ist eine gasdurchlässige
Stützschicht 20 angeordnet, die eine flächige Anlage des
Innenbehälters 1 am Behältermantel des Außenbehälters 2
verhindert. Anstelle einer Stützschicht 20, z. B. in Form
eines Gewebes, Bläschenfolie, Schaum-Kunststoff u. dgl.,
kann der für die Leckageüberwachung erforderliche Abstand
zwischen Innenbehälter 1 und Außenbehälter 2 auch dadurch
sichergestellt werden, daß die äußere Oberfläche des
Innenbehälters 1 eine aus punktförmigen und/oder linien-förmigen
Erhebungen bestehende Oberflächenstruktur aufweist.To the jacket space between the
Bei der Aufstellung in Gebieten, die als Überflutungsgebiete
gelten, muß der doppelwandige Tank
gesichert werden, damit er im Falle einer Überflutung des
Bodenbereiches nicht unter der auf ihn einwirkenden
Auftriebskraft aufschwimmt. Die Sicherung des Tanks erfolgt
mit Klauen 21, die auf dem Behälterdeckel 6 aufliegen. Sie
sind in den Eckbereichen angeordnet und mit Zugankern im
Lagerraumboden gegen den Behälterdeckel spannbar (Fig. 5).When installing in areas that are considered flood areas
