Abstract

Spherical pressure vessels are assembled from twin hemispherical shells which butt together at their rims, where the joint is covered by an internal band and by an external bandage where the latter is made of layers of mat and of cloth impregnated with (polyester) resin and varying in width to decrease progressively in overall thickness from the level of the joint to the borders of the bandage. The inner most layer of the bandage is of mat 50-75% of the overall bandage width. The adjacent layer is of cloth 25-50% of the overall bandage width, with successive layers getting wider until the outermost layer, which is of cloth, is of the overall width of the bandage. Used for reservoirs for holding carbonated drinsk, esp. for spheres of approx. 1.25 m dia. to be assembled in hotel cellars for storing beer at working pressures 15 atm. The cloth layers enhance the hoop strength of the joint biaxially. The mat layers enhance the shear strength of the joint.

Description

Drucktank für kohlendioxydhaltige GetränkePressure tank for carbonated drinks

Die Erfindung betrifft einen Drucktank für kohlendioxydhaltige Getränke, bestehend aus zwei miteinander verklebten Kunststoff-Halbschalen.The invention relates to a pressure tank for beverages containing carbon dioxide, consisting of two plastic half-shells glued together.

Ein derartiger Drucktank ist bekannt (DT-PS 14 86 698).Such a pressure tank is known (DT-PS 14 86 698).

Bei diesem bekannten Drucktank sind die Halbschalen längs ihres Randes durch eine Art Nut-Feder-Verbindung miteinander verbunden und thermisch verschweißt bzw. verklebt. Die beiden Halbschalen sind von zwei Kappen eingefaßt, welche ebenfalls miteinander verschweißt und verklebt sind und dadurch den Druck des Tankes teilweise mit aufnehmen. Die Kappen sind so geformt, daß der Drucktank insgesamt die Form eines Fasses hat.In this known pressure tank, the half-shells are along their edge connected to one another by a kind of tongue and groove connection and thermally welded or glued. The two half-shells are surrounded by two caps, which are also are welded and glued together and thereby partially reduce the pressure of the tank with record. The caps are shaped so that the pressure tank has the overall shape of a barrel.

Der Erfindung liegt die Aufgabe zugrunde, einen Drucktank für kohlendioxydhaltige Getränke zu schaffen, der auch ohne die Verwendung von zusätzlichen Kappen dem für die Halterung eines kohlendioxydhaltigen Getränkes, insbesondere Bier, erforderlichen Druck standhält.The invention is based on the object of a pressure tank for carbon dioxide-containing To create drinks that are suitable for even without the use of additional caps the holder of a carbon dioxide-containing beverage, especially beer, required Withstands pressure.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Kunststoff glasfaserverstärkt ist, daß an der Tank-Innenseite ein die Fuge überdeckender und die beiden Randbereiche der Halbschalen verbindender Steg angeklebt ist, und daß an der Tankaussenseite die Randbereiche der beiden Halbschalen durch eine die Fuge überdeckenden, mit Klebstoff ge-tränkten Laminatverband miteinander verbunden sind, der aus übereinander geschichteten bidirektional auf Zug belastbaren Gewebestreifen und saugfähigen Mattestreifen besteht.The object is achieved according to the invention in that the plastic glass fiber reinforced that on the inside of the tank a joint covering and the web connecting the two edge regions of the half-shells is glued, and that on the outside of the tank, the edge areas of the two half-shells through a joint covering, adhesive-soaked laminate dressing are connected to one another, made of layered, bidirectional, tensile strength fabric strips and absorbent mat strips.

Die Gewebestreifen verhindern durch ihre bidirektionale Belastbarkeit einerseits, daß sich der Behälter in Umfangsrichtung des Laminatverbandes über ein zulässiges Maß ausdehnt und andererseits, daß die beiden Halbschalen auseinander gedrückt werden. Die Mattestreifen saugen die notwendige Menge Klebstoff auf und bilden eine Armierung in dem Laminatverband.The fabric strips prevent with their bidirectional load capacity on the one hand that the container in the circumferential direction of the laminate association over a permissible extent and on the other hand that the two half-shells apart be pressed. The mat strips absorb the necessary amount of adhesive and form a reinforcement in the laminate bandage.

Es soll in diesem Zusammehang erwähnt werden, daß es von einem aus zwei Halbschalen bestehenden Behälter grundsätzlich bekannt ist (DT-PS 11 70 314) die beiden Randbereiche der Halbschalen an der Innenseite des Behälters durch einen Steg miteinander zu verkleben. An der Aussenseite ist Jedoch kein Laminatverband vorgesehen, sondern es sind dort zwei Randflansche der beiden Halbschalen miteinander verklebt. Es liegt kein Hinweis vor, daß der bekannte Behälter dem zur Lagerung eines kohlendioxyhaltigen Getränkes erforderlichen Druck standhalten kann.In this context it should be mentioned that it starts from one point of view two half-shells existing container is basically known (DT-PS 11 70 314) the two edge areas of the half-shells on the inside of the container through one Glue the bridge together. However, there is no laminate bandage on the outside provided, but there are two edge flanges of the two half-shells with each other glued. There is no indication that the known container is used for storage a carbon dioxide-containing beverage can withstand the required pressure.

Eine zweckmäßige Weiterbildung der Erfindung kann darin bestehen, daß mehrere Mattestreifen und Gewebestreifen welchselweise übereinander geschichtet sind. Dabei hat es sich als zweckmäßig erwiesen, wenn innen ein Mattestreifen und außen ein Gewebestreifen vorgesehen wird.An expedient further development of the invention can consist in that several strips of mat and strips of fabric are alternately layered on top of each other are. It has proven to be useful if there is a mat strip inside and a fabric strip is provided on the outside.

Weiterhin sollte der Laminatverband zweckmäßigerweise so dimensioniert werden, daß er über der Fuge am dicksten ist und zu den Seiten hin in der Dicke kontinuierlich abnimmt. Ein solcher Laminatverband zeichnet sich dadurch aus, daß er sich kontinuierlich an die Form der Halbschalen anpaßt und dennoch eine hohe Verbindungsfestigkeit aufweist. Eine hügelförmige Gestalt des Laminatverbandes läßt sich beispielsweise dadurch erreichen, daß die Ubereinanderliegenden Streifen unterschiedliche Breite haben.Furthermore, the laminate bandage should expediently be dimensioned in this way be that it is thickest above the joint and in thickness towards the sides continuously decreases. Such a laminate bandage stands out characterized in that it continuously adapts to the shape of the half-shells and yet has a high connection strength. A hilly shape of the laminate bandage can be achieved, for example, that the strips lying one above the other have different widths.

Als besonders günstig für die an ihn gestellten Anforderungen hat sich ein Laminatverband erwiesen, der dadurch gekennzeichnet ist, daß die innerste Schicht eine sich über 50 bis 7596 der Breite des Laminatverbandes erstreckender Mattestreifen ist, daß die zweite Schicht von innen ein sich etwa über 25 bis 5096 der Breite des Laminatverbandes erstreckender Gewebestreifen ist, daß die äußere Schicht ein Gewebestreifen ist, der sich über die volle Breite des Laminatverbandes erstreckt, daß die zweite Schicht von aussen ein Mattestreifen ist, daß die Schichten zwischen der zweiten Schicht von innen und der zweiten Schicht von aussen aus Gewebestreifen bestehen und daß die Breite der Streifen ab der zweiten Schicht von innen nach außen stufenweise zunimmt.As particularly favorable for the demands placed on him A laminate dressing has been found, which is characterized in that the innermost Layer one extending over 50 to 7596 the width of the laminate dressing Matt strip is that the second layer from the inside is about 25 to 5096 the width of the laminate dressing extending fabric strip is that the outer Layer is a strip of fabric that extends over the full width of the laminate dressing extends that the second layer from the outside is a mat strip that the layers between the second layer from the inside and the second layer from the outside made of fabric strips exist and that the width of the strips from the second layer onwards from the inside out gradually increases.

Als Klebstoff kann ein Kunstharz, vorzugsweise Polyesterharz verwendet werden.A synthetic resin, preferably polyester resin, can be used as the adhesive will.

Für die Belastbarkeit der Verbindung hat es sich als förderlich erwiesen, wenn die zu beklebenden Randbereiche der Halbschalen vor dem Bekleben aufgerauht werden.For the load-bearing capacity of the connection, it has proven to be beneficial if the edge areas of the half-shells to be glued are roughened before gluing will.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen beschrieben.An exemplary embodiment of the invention is described below with reference to FIG Drawings described.
