Description

Dichtungsvorrichtung an Schwimmdecken Es ist bekannt, daß Schwimmdecken von Behältern für flüssige, leicht in den gasförmigen Zustand übergehende Brennstoffe gegen die Behälterwand gut abgedichtet werden. Bekannte Dichtvorrichtungen solcher Schwimmdecken haben eine elastische zylinderförmige Dichtschürze, die durch Andrückvorrichtungen in zwei Höhenlagen der Schürze an die Behälterwand gepreßt werden. Als Andrückmittel dienen Federn, Gewichte od. dgl. Man hat auch schon das Eigengewicht der Dichtschürze dazu benutzt, über schräg gestellte Anlenkhebel die Anpreßkraft zu erzeugen.Sealing device on floating ceilings It is known that floating ceilings of containers for liquid fuels which easily change into the gaseous state be well sealed against the container wall. Known sealing devices such Floating covers have an elastic, cylindrical sealing skirt that is secured by pressing devices be pressed against the container wall at two levels of the skirt. As a pressing agent springs, weights or the like are used. You also have the dead weight of the sealing skirt used to generate the contact pressure via angled linkage levers.

Allerdings hat man noch nicht zufriedenstellend erreicht, durch das Eigengewicht der Schürze nahezu gleich große Anpreßdrücke in beiden Höhenlagen zu erzeugen, so daß man auf zusätzliche, unter der Wirkung einer Fremdkraft stehende Federn od. dgl. nicht verzichten konnte.However, one has not yet achieved satisfactory, through that Dead weight of the apron is almost the same contact pressure at both altitudes generate, so that one stands on additional, under the effect of an external force Feathers or the like could not do without.

Die Erfindung bezweckt, eine Dichtvorrichtung zu schaffen, bei der in beiden Höhenlagen allein das Eigengewicht der Schürze eine nahezu gleiche oder beliebig unterschiedliche Anpreßkraft erzeugt. über dies bezweckt die Erfindung, das genannte Ziel in konstruktiv einfacher Weise zu erreichen. The invention aims to provide a sealing device in which In both altitudes alone the weight of the apron is almost the same or any different contact pressure generated. This is the purpose of the invention, to achieve the stated goal in a structurally simple manner.

Gemäß der Erfindung sind bei der Dichtungsvorrichtung, deren elastische Schürze in bekannter Weise durch in Abstand übereinanderliegende Schrägstäbe an die Behälterwand gedrückt ist, die unteren Enden der oberen Schrägstäbe in bekannter Weise vertikal verschiebbar an der vertikalen Wand der Schwimmdecke gelagert. Dieselben stützen sich hierbei gegen die oberen Enden von schrägen Zwischen stäben, deren untere Enden auf den unteren, insbesondere biegeelastisch ausgebildeten Schrägstäben gelenkig gelagert sind, ab. Die unteren Schrägstäbe pressen sich dadurch gleitend gegen die Schürze an. According to the invention are in the sealing device, the elastic Apron in a known manner by spaced oblique bars on top of each other the container wall is pressed, the lower ends of the upper inclined bars in known Way mounted vertically on the vertical wall of the floating ceiling. The same support themselves against the upper ends of inclined intermediate rods, whose lower ends on the lower, in particular flexurally elastic, inclined rods are articulated, from. As a result, the lower inclined bars are pressed against each other in a sliding manner against the apron.

Bei der erfindungsgemäßen Dichtungsvorrichtung dienen also die oberen Schrägstähe in bekannter Weise als Anpreßvorrichtungen. Hiergegen erhalten die unteren Schrägstähe ihre Andrückkraft mittelbar über die oberen Schrägstäbe. so daß in den Stähen ein statisch bestimmtes System besteht. Durch die biegeelastische Ausführung der unteren Schrägstähe erhält das Stabsystem lediglich eine vorteilhafte elastische Weichheit. In the case of the sealing device according to the invention, the upper ones are used Skew in a known manner as pressing devices. Against this, the lower ones get Their pressing force would be inclined indirectly via the upper inclined bars. so that in the There is a statically determined system. Due to the flexible design the rod system only receives an advantageous elasticity of the lower slant Softness.

In zweckmäßiger Ausführungsform können die Stäbe zur Behälterwand hin gegabelt sein. In an expedient embodiment, the rods can be attached to the container wall be forked down.

In der Zeichnung ist der Gegenstand der Erfindung an einem Ausführungsheispiel dargestellt. Es zeigt Fig. 1 schematisch und ausschnittsweise einen Behälter mit Schwimmdecke und Dichtungsvorrichtung im Vertikalschnitt. In the drawing, the subject of the invention is based on an exemplary embodiment shown. It shows Fig. 1 schematically and partially with a container Floating cover and sealing device in vertical section.

Fig. 2 das Stabsystem der Dichtungsvorrichtung nach Fig. 1 in Ansicht gemäß Pfeilrichtung II. FIG. 2 shows the rod system of the sealing device according to FIG. 1 in view according to arrow direction II.

In einem Behälter 1 ist eine Schwimmdecke 2 auf und al, beweglich. An der Behälterwand liegt eine aus elastisch leicht verformbarem Stoff bestehende zylinderförmige Schürze 3 an, die am oberen Ende abgebogen ist und dort über ein nachgiebiges Verhindungsstück 4 mit der Schwimmdecke 2 verhunden ist. An einem Paar Gelenkaugen 5 a sitzt ein gabelförmiger oberer Schrägstab 5. dessen unteres Ende in einem gabelförmigen Gleitstück 8 gelagert ist und dabei auf dem oberen Ende eines ebenfalls gabelförmigen Zwischenstabes 7 aufsitzt. Die Schenkel des Zwischenstabes 7 münden in Gelenkösen 6b von unteren Schrägstäben 6, die als Blattfedern ausgebildet sind. Die unteren Schrägstähe 6 sind unten in Gelenkaugen 6a gelagert und hahen ohen kufenartige Abbiegungen 6 c. In a container 1, a floating cover 2 is on and al, movable. On the container wall is made of an elastic, easily deformable material cylindrical apron 3, which is bent at the upper end and there over a compliant prevention piece 4 is connected to the floating cover 2. On a couple Joint eyes 5 a sits a fork-shaped upper inclined rod 5. its lower end is mounted in a fork-shaped slider 8 and while on the upper end of a also fork-shaped intermediate rod 7 is seated. The legs of the intermediate rod 7 open into hinge eyes 6b of lower inclined rods 6, which are designed as leaf springs are. The lower oblique bars 6 are mounted and hahen at the bottom in hinge eyes 6a without skid-like bends 6 c.
