Description

Titel : Leckanzeigevorrichtung und Vorrichtung zum Schutz gegen chemische und pysikalische Angriffe des Stahlbleches durch den Inhalt, an Lagerbehältern für wassergefährdende Flüssigkeiten.Title: Leak detection device and device for protection against chemical and physical attacks on the steel sheet by the contents, on storage containers for water polluting liquids.

Beschreibung : Die Erfindung betrifft eine metallinnehnhülle, welche nachträglich in einen Mineralölbehälter, in Einzelteilen durch das Mannloch eingebracht, im Innern desselben montiert werden kann.Description: The invention relates to a metal inner shell which retrofitted in a mineral oil tank, introduced in individual parts through the manhole, can be mounted inside the same.

Die Hülle hat die Aufgabe den Tank doppelwandig zu machen und das Lagergut, vor allem die Verunreinigungen im Lagergut (Seewasser etc.) von den Stahlblechwanden des Behälters Fernzuhalten, und permanent dessen Dichtheit zu überwachen.The purpose of the shell is to make the tank double-walled and that Stored goods, especially the contamination in the stored goods (sea water, etc.) from the sheet steel walls keep away from the container and permanently monitor its tightness.

Der Grund eine MetallkUlle su verwenden liegt bei der umstrittenen olbestandigkeit der bisher benutzten Kunststoffe. Zudem sind Konststoffinnenhüllen nach langer Benutzung empfindlich, und weden bei den routinemäßigen Tankreinigungen leicht beschädigt.The reason to use a metal bulb is controversial oil resistance of the plastics used so far. In addition, there are inner layers of plastic Sensitive after long periods of use, and will be used during routine tank cleaning slightly damaged.

Ein weiterer Nachteil der Kunststoffhülle ist ihre Anschmiegsamkeit.Another disadvantage of the plastic cover is its flexibility.

Obwohl bei den bekannten Verfahren die Tankinnenwände mit porösem Schaumstoff belegt werden, kommt es doch auf die Dauer unter dem Hydrosien Druck de , t . ca d c' richen Hülle und Tankwandung so Zusammengedrückt wird daß sich das Vakuum auf welchem die Uberwachung beruht, nicht bis zu der am schwersten beladenen Zone am Tankboden (Sohle) fortpflanzt und Undichtigkeiten von dort garnicht registriert werden. Zudem verformt sich die Hülle mit wechselnder Befüllung ständig, was zu Materialermüdung führt.Although in the known method the tank inner walls with porous Foam are covered, but in the long run it comes under the hydrosia pressure de, t. ca d c 'richen Shell and tank wall so pressed together the vacuum on which the monitoring is based is not up to the am heaviest loaded zone on the tank bottom (sole) propagates and leaks from not be registered there. In addition, the shell deforms with changing Constant filling, which leads to material fatigue.

Der Erfindung ligt nun die Aufgabe zugrunde diese Nachteile auf folgende Weise auszuschliesen : 1. Die Innenhülle besteht aus Metall. Welches Metall, richtet sich nachden chemischen Eigenschaften des Lagergutes.The invention now ligt the object of these disadvantages on the following Way to exclude: 1. The inner shell is made of metal. Which metal aligns according to the chemical properties of the stored goods.

Es kommen praktisch alle als Blech erhältlichen Metalle in Frage. Die Blechdicke richtet sich nach der vorauszusehenden Beanspruchung, und der Möglichkeit dem Blech die dem Tank entsprechende Form zu geben. Die Nahte können gelötet, geschweißt, glasfasergespritzt, genietet oder geklebt werden, wobei letzteres der gangbarste Weg sein dürfte. Practically all metals available as sheet metal can be used. The sheet thickness depends on the anticipated stress and the possibility to give the sheet the shape that corresponds to the tank. The seams can be soldered, welded, fiberglass sprayed, riveted or glued, the latter being the most common Should be gone.

2. Der Abstand zur Behälterwand wird durch Körner (z.b.Quarzsand) welche in Epoxydharz eingegossen sind hergestellt.2. The distance to the container wall is determined by grains (e.g. quartz sand) which are cast in epoxy resin.

Dadurch erhält man eine Oberfläche, bei welcher die abstützenden Erhebungen verhältnismäßig spitz und zahlreich sind, so daß der Flüssigkeitsdruck nicht den Luftdurchgang zwischen Hülle und Tank behindern kann. This gives a surface in which the supporting Elevations are relatively pointed and numerous, so that the fluid pressure cannot obstruct the passage of air between the shell and the tank.

Da Da die oben beschriebene Bleghhülle mit der Domdeckeldichtfläche abgedichtet wird und das Leokanzeigegerät seitlich an der Zarge des Doms mit dem Zwischenraum verbunden ist, wird die Überwachung auch dann nicht beeinflusst wenn der Domdeckel geoffnetund der Tank gereinigt bzw. begangen wird.Da Da the above described sleeve with the dome cover sealing surface is sealed and the Leokanzeiggerät laterally on the frame of the cathedral with the Is connected, the monitoring is not affected even if the dome lid is opened and the tank is cleaned or walked on.

Die Dichtheitsüberwachmg selbst kann auf zwei verschidene Arten durchgeführt werden. a. Indem der Zwischenraum mit einer Flüssigkeit gefüllt ist welche über eine Leitung mit einem üblichen Leckanzeigegerät für doppelwandige Behälter verbunden ist. b. Indem der Zwischenraum evakuiert wird, und über einen Unterdruckschalter mit der Alarmeinrichtung verbunden ist.The leak monitoring itself can be carried out in two different ways will. a. By filling the gap with a liquid which is above a line connected to a conventional leak detector for double-walled containers is. b. By evacuating the space and using a vacuum switch is connected to the alarm device.

Es wird angstrebt, die gesamte Amlage so abzudichten, daß auf eine fest installierte Vakuumpumpe verzichtet werden kann, so daß lediglich bei den regelmäßigen Kontroll-Inspektionen das evtwi. geringfügig abgesunkene Vakuum wieder hergestellt wird.The aim is to seal the entire system so that on one Fixed vacuum pump can be dispensed with, so that only with the regular Control inspections the possibly. slightly decreased vacuum restored will.
