Description

Die Erfindung betrifft ein Stahlfaß, bestehend aus einem Außenbehälter mit einem äußeren Faßmantel mit kreisförmigem Querschnitt und aufgefalztem Ober- und Unterboden und einem paßgenau darin angeordneten Innenbehälter mit einem inneren Behältermantel mit aufgefalztem Ober- und Unterboden, und wobei der Oberboden des Außenbehälters mit dem Oberboden des Innenbehälters im Bereich eines Faßspundes miteinander verbunden sind.
Ein Stahlfaß mit diesen Merkmalen ist bekannt (DE-A-2 134 034), wobei der Ober- und Unterboden mit dem Faßmantel jeweils durch einen Mehrfachfalz miteinander verbunden sind. Solche Fässer werden vor allen Dingen als genormte 55-US Gallonen-Fässer bergestellt (EP-A-0 162 873), wobei diese Fässer insbesondere für den Transport umweltgefährdender Güter dienen. Durch Anwendung eines besonderen Verfahrens lassen sich diese Fässer ISO-containergerecht ausbilden, indem solche ISO-Container mit diesen Fässern optimal beladen werden können. Die besonderen und immer strenger werdenden gesetzgeberischen Auflagen führen jedoch dazu, daß solche Gefahrgutfässer grundsätzlich aus Stahl oder Edelstahl gefertigt sein müssen, wobei das Gefahrgut, wie beispielsweise Öle, Farben, Lacke, Emulsionen, Verdünnungen u.dgl. in solchen Fässern nicht gelagert werden darf. Um eine solche Lagerung zu ermöglichen, ist man dazu übergegangen, die Fässer in herkömmlichen Auffangwannen, z.B. Faßstapelpaletten anzuordnen, was jedoch mit einem erheblichen Kostenfaktor verbunden ist und darüber hinaus dem Faß als klassischem, vom Gewicht her noch manuell beherrschbaren Einzelgebinde seine Ortsbeweglichkeit bzw. Mobilität genommen wird.
Es ist ein doppelwandiges Faß bekannt US-A-22 45 430), bei dem der innere Behälter mit seinem Mantel und seinem aufgefalzten Ober- und Unterboden paßgenau innerhalb des äußeren Faßmantels mit Ober- und Unterboden angeordnet ist und die Falze des aufgefalzten Ober- und Unterbodens innerhalb der Falze des aufgefalzten Ober- und Unterbodens liegen. Der dem äußeren Faßmantel zugeordnete Oberboden ist mit dem Oberboden des inneren Behälters im Bereich eines Faßspundes verbunden. Der wesentliche Nachteil dieses bekannten Stahlfasses besteht darin, daß die beiden Behälter im Bereich der Ober- und Unterböden nur durch eine einzige Falzverbindung miteinander verbunden sind und somit keine Eigenständigkeit zwischen dem Innen- und dem Außenfaß besteht. Dadurch ergibt sich auch eine erheblich ungünstigere Falzverbindung, da vier Bleche zu einem Falz geformt werden müssen. Der schützende Hohlraum zwischen Innen- und Außenfaß ist nicht vorhanden und somit auch keine Leckageabfragung zwischen Innen- und Außenmantel möglich. Hinsichtlich der bei solchen Fässern gegebenen Beanspruchungsarten fehlen auch notwendige Knautschzonen.The invention relates to a steel drum, consisting of an outer container with an outer drum shell with a circular cross-section and folded top and bottom and an inner container with a precise fit therein with an inner container shell with folded top and bottom, and wherein the top of the outer container with the top of the Inner container are connected to each other in the region of a barrel bung.
A steel drum with these features is known (DE-A-2 134 034), the top and bottom bottoms being connected to the drum casing by a multiple fold. Such barrels are primarily manufactured as standardized 55-US gallon barrels (EP-A-0 162 873), these barrels being used in particular for the transport of environmentally hazardous goods. Using a special process, these barrels can be designed to be ISO container-compatible, since such ISO containers can be optimally loaded with these barrels. The special and increasingly strict legislative requirements, however, mean that such dangerous goods drums must be made of steel or stainless steel, whereby the dangerous goods such as oils, paints, varnishes, emulsions, thinners and the like. must not be stored in such barrels. In order to enable such storage, it has become common to arrange the drums in conventional collecting trays, e.g. drum stack pallets, but this is associated with a considerable cost factor and, moreover, the drum, as a classic, manually controllable individual container, has its mobility or mobility is taken.
There is a double-walled barrel known US-A-22 45 430), in which the inner container with its jacket and its crimped top and bottom are arranged precisely within the outer barrel jacket with top and bottom and the folds of the crimped top and bottom Underbody lie within the folds of the folded top and bottom panels. The top shelf assigned to the outer barrel jacket is connected to the top of the inner container in the area of a barrel bung. The main disadvantage of this known steel barrel is that the two containers in the area of the top and bottom floors are connected to each other only by a single fold connection and thus there is no independence between the inner and the outer barrel. This also results in a considerably less favorable fold connection, since four sheets have to be formed into a fold. The protective cavity between the inner and outer barrel is not available and therefore no leakage detection between the inner and outer jacket is possible. With regard to the types of stress given to such drums, there are also no necessary crumple zones.

Der Erfindung liegt die Aufgabe zugrunde, ein Stahlfaß sowie ein Verfahren zu seiner Herstellung vorzuschlagen, das sowohl zum Transport als auch zur Lagerung und nicht nur zur Zwischenlagerung umweltgefährdender Güter bei hoher Stabilität geeignet ist.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß bei den als selbständige Behälter mit Faßmantel bzw. Behältermantel und Ober- und Unterboden ausgebildeten Behältern, der Innenbehälter sich mit seinen Falzverbindungen im Bereich des größten Durchmessers des Falzes und seinen Positivsicken an der Innenseite des Faßmantels abstützt.The invention is based on the object of proposing a steel drum and a method for its production which are suitable both for transport and for storage and not only for the intermediate storage of environmentally hazardous goods with high stability.
This object is achieved according to the invention in that, in the case of the containers designed as independent containers with a drum jacket or container jacket and top and bottom, the inner container with its fold connections is supported in the area of the largest diameter of the fold and its positive beads on the inside of the drum jacket .

Weiterhin wird vorgeschlagen, daß der Oberboden des inneren weiteren Behälters im Bereich der Faßspundlöcher nach außen gewölbt und der Oberboden des äußeren Faßmantels der Form des ersten Oberbodens angepaßt gegen diesen geformt ist und daß zum Verbinden der Oberböden an den Faßspundlöchern jeweils ein Verbindungsflansch eingesetzt ist.It is also proposed that the top of the inner further container in the area of the bung holes be curved outwards and that the top of the outer barrel shell be shaped to match the shape of the first top and that a connecting flange is used to connect the top floors to the bung holes.

Es ist vorteilhaft, daß der Oberboden des äußeren Faßmantels im Bereich der Faßspundlöcher vergrößert ausgeschnitten und mit dem anderen Oberboden verschweißt ist.It is advantageous that the upper floor of the outer barrel casing is cut out enlarged in the region of the barrel bung holes and welded to the other upper floor.

Es wird weiterhin vorgeschlagen, daß die Oberböden an den Faßspundlöchern im Randbereich gegeneinander eingezogen und zu den Faßspundlöchern hin treppenartige Absätze aufweisen.It is further proposed that the top bottoms at the barrel bung holes be drawn in against one another in the edge region and have stair-like shoulders towards the barrel bung holes.

Es ist weiterhin vorteilhaft, daß im Oberboden des äußeren Faßmantels eine Prüföffnung vorgesehen ist.It is also advantageous that a test opening is provided in the top floor of the outer barrel casing.

Eine vorteilhafte Ausführungsform des Fasses besteht darin, daß das äußere Faß ein genormtes (DIN 6643) 55-US-Gallonen-Faß ist, in das ein genormtes (DIN 6643) Innenfaß mit geringeren Abmessungen eingesetzt ist.An advantageous embodiment of the barrel is that the outer barrel is a standardized (DIN 6643) 55-US-gallon barrel, in which a standardized (DIN 6643) inner barrel is used with smaller dimensions.

Ein vorteilhaftes Verfahren zum Herstellen eines derartigen Stahlfasses, mit einem äußeren Faßmantel, an den ein Unterboden angefalzt wird, besteht darin, daß in den äußeren Faßmantel ein weiterer Stahlbehälter, bestehend aus einem weiteren Faßmantel mit aufgefalztem Ober- und Unterboden paßgenau eingesetzt wird, daß der erste Oberboden des äußeren Faßmantels mit dem Oberboden des weiteren Stahlbehälters verbunden wird und daß der erste Oberboden auf den oberen Rand des Faßmantels aufgefalzt wird.An advantageous method for producing such a steel barrel, with an outer barrel jacket to which an underbody is crimped, is that in the outer barrel jacket another steel container, consisting of another barrel jacket with a crimped top and bottom, is used so that the the first top floor of the outer barrel jacket is connected to the top floor of the further steel container and that the first top floor is crimped onto the upper edge of the barrel jacket.

Ein weiterer vorteilhafter Verfahrensschritt besteht darin, daß die beiden Oberböden durch Flansche im Bereich der Faßspundlöcher verbunden werden.Another advantageous process step is that the two top floors are connected by flanges in the region of the bung holes.

Schließlich geht man so vor, daß die beiden Oberböden im Bereich der Flansche bzw. der Faßspundlöcher miteinander verschweißt werden.Finally, one proceeds in such a way that the two top floors are welded together in the area of the flanges or the bung holes.

Die Erfindung bringt den wesentlichen Vorteil, daß ein doppelwandiges Sickenspundfaß vorliegt, das den höchsten Sicherheitsanforderungen hinsichtlich des Transports und der Lagerung von umweltgefährdenden Gütern genügt. Bedingt durch die Paßgenauigkeit des Innenfasses zum Außenfaß ist jederzeit ein einwandfreier Sitz gewährleistet, so daß ein solches Faß den geforderten Prüfungen durch Fallversuche und Innendruckbeanspruchungen genügt. Zur Herstellung des Fasses können die herkömmlichen Maschinen und Anlagen verwendet werden. Insbesondere kann das Faß aus zwei DIN-gerechten Fässern erstellt werden, indem das Außenfaß als 55-US-Gallonen-Faß nach DIN 6643 und das Innenfaß nach der gleichen Norm, jedoch mit etwas verringerten Außenabmessungen hergestellt werden kann. Durch die Ausgestaltung der beiden Oberböden im Bereich der Faßspunde befinden sich die Spundlöcher in einem derartigen Bereich, daß ein Anschluß an die automatischen Befüll- und Stopfenverschraubanlagen gewährleistet ist. Durch die weiterhin besonders gestaltete Ausbildung der beiden Oberböden im Bereich der Faßspunde wird bei Belastung der eigentliche Verschluß entlastet, Weiterhin ergibt sich durch die Ausformung der Oberböden im Bereich der Faßspunde eine Restentleerbarkeit des Fasses. Bei Anwendung des erfindungsgemäßen Verfahrens lassen sich auch gebrauchte Stahlfässer zu den erfindungsgemäßen doppelwandigen Fässern rekonditionieren.The invention has the essential advantage that a double-walled bung-type drum is available which meets the highest safety requirements with regard to the transport and storage of environmentally hazardous goods. Due to the accuracy of fit of the inner barrel to the outer barrel, a perfect fit is guaranteed at all times, so that a such a barrel meets the required tests by drop tests and internal pressure stresses. Conventional machines and systems can be used to manufacture the barrel. In particular, the keg can be created from two DIN-compatible kegs by producing the outer keg as a 55-US gallon keg according to DIN 6643 and the inner keg according to the same standard, but with slightly reduced external dimensions. Due to the design of the two top floors in the area of the barrel bung, the bung holes are located in such an area that a connection to the automatic filling and plug screwing systems is ensured. Due to the still specially designed design of the two top floors in the area of the barrel bungs, the actual closure is relieved of load. Furthermore, the shape of the top floors in the area of the barrel bores results in a residual emptying of the barrel. When using the method according to the invention, used steel drums can also be reconditioned to the double-walled drums according to the invention.

Das in den Figuren 1 und 2 dargestellte Faß besteht aus einem äußeren Stahlfaß mit einem zylindrischen äußeren Faßmantels 1 mit Unterboden 3 und Oberboden 2. Die Verbindung von Oberboden 2 bzw. Unterboden 3 mit dem Faßmantel 1 erfolgt durch Falzverbindungen 7 bzw. 8. Weiterhin besitzt der äußere Faßmantel positive Sicken 13, die auch als Rollsicken dienen.The barrel shown in Figures 1 and 2 consists of an outer steel barrel with a cylindrical outer barrel jacket 1 with bottom 3 and top 2. The connection of top 2 and bottom 3 with the barrel 1 is made by folded joints 7 and 8. Furthermore has the outer barrel jacket positive beads 13, which also serve as rolling beads.

In dieses äußere Stahlfaß ist ein entsprechend ausgebildetes inneres Stahlfaß mit einem zylindrischen Behältermantel 4 sowie Oberboden 5 und Unterboden 6 paßgenau eingesetzt, wobei der Oberboden 5 bzw. der Unterboden 6 an Falzverbindungen 9 bzw. 10 mit dem Faßmantel 4 verbunden sind. Weiterhin ist der Behältermantel 4 mit positiven Sicken 14 versehen. Der Durchmesser dieser Sicken 14 bzw. über den größten Durchmesser der Falzverbindungen 9 bzw. 10 ist derart, daß sich das Innenfaß an der Innenseite 16 des Faßmantels 4 abstützt.In this outer steel barrel, a correspondingly constructed inner steel barrel with a cylindrical container jacket 4 and top shelf 5 and bottom shelf 6 is inserted with an exact fit, the top shelf 5 and the bottom shelf 6 being connected to the barrel jacket 4 at fold connections 9 and 10, respectively. Furthermore, the container jacket 4 is provided with positive beads 14. The diameter of these beads 14 or over the largest diameter of the fold connections 9 or 10 is such that the inner barrel is supported on the inside 16 of the barrel jacket 4.

Die Verbindung dieser beiden ineinander gesetzten Stahlfässer erfolgt im Bereich der Faßspundlöcher 11 bzw. 12, wobei in Fig. 3 eine erste Ausführungsform einer solchen Verbindungsmöglichkeit dargestellt ist. Dazu ist der Oberboden 2 des äußeren Stahlfasses im Bereich eines derartigen Faßspundloches 11 oder 12 stufenförmig eingezogen, indem zunächst in einer ersten Stufe 21 am Übergang des Deckelrandes in den Falz 7 der Oberboden an dem Falz 9 des inneren Stahlfasses anliegt. In einer anschließenden schrägen Abstufung 24 wird der Oberboden 2 dem Oberboden 5 des inneren Stahlfasses angeglichen, der seinerseits über eine nach außen ansteigende schräge Abstufung 23 dem Oberboden 2 angenähert ist. Nach weiteren treppenartigen Absätzen 18 der beiden Oberböden 2, 5 erfolgt die Verbindung an Faßspundlöchern 11 bzw. 12 mit Hilfe eines Verbindungsflansches 17, der einen an der Unterseite des inneren Oberbodens 5 anliegenden umlaufenden Rand 25 aufweist, der mit einem zylindrischen Abschnitt durch die Öffnung des Faßspundloches 11 bzw. 12 hindurchgeführt ist und der außen eine Umbördelung 22 aufweist, die sich um die hochstehenden Ränder der beiden Oberböden 2, 5 legt. Im Oberboden 2 des äußeren Stahlfasses ist eine Prüföffnung 15 vorgesehen.The connection of these two steel barrels placed one inside the other takes place in the region of the barrel bung holes 11 and 12, a first embodiment of such a connection possibility being shown in FIG. 3. For this purpose, the top floor 2 of the outer steel barrel is drawn in stepwise in the area of such a barrel bung 11 or 12, in that in a first step 21 at the transition of the lid edge into the fold 7, the top floor rests against the fold 9 of the inner steel barrel. In a subsequent oblique gradation 24, the top floor 2 is adjusted to the top floor 5 of the inner steel barrel, which in turn is above an outwardly increasing inclined step 23 is approximated to the top floor 2. After further stair-like shoulders 18 of the two top floors 2, 5, the connection to barrel bung holes 11 and 12 takes place with the aid of a connecting flange 17 which has a circumferential edge 25 abutting the underside of the inner top floor 5, which has a cylindrical section through the opening of the Barrel bung hole 11 or 12 is passed through and has a flange 22 on the outside, which surrounds the upstanding edges of the two top floors 2, 5. A test opening 15 is provided in the top floor 2 of the outer steel barrel.

Bei der in den Figuren 4 und 5 gezeigten Ausführungsform ist der obere Oberboden 2 mit einem gegenüber dem Faßspundloch 11, 12 vergrößerten Ausschnitt 19 versehen und es wird der entsprechende kreisförmige Rand des oberen Oberbodens 2 an diesem Ausschnitt 19 mit dem unteren Oberboden 5 verschweißt, wobei eine Schweißnaht 20 vorhanden ist.In the embodiment shown in FIGS. 4 and 5, the upper top floor 2 is provided with a cutout 19 which is enlarged compared to the barrel bunghole 11, 12 and the corresponding circular edge of the upper top floor 2 is welded to the lower top floor 5 at this cutout 19, wherein a weld seam 20 is present.

Das am meisten benutzte Gebinde ist das genormte 55-US-Gallonen-Faß, das nach DIN 6643 ISO-containergerecht oder nicht ISO-containergerecht gefertigt sein kann. Mit diesen Abmessungen ist das Außenfaß zu gestalten. Das in dieses Außenfaß einzusetzende Innenfaß ist ebenfalls normgerecht zu fertigen und zwar nach der gleichen DIN-Norm 6643 mit verringerten Abmessungen.The most frequently used container is the standardized 55-US-gallon barrel, which can be made according to DIN 6643 ISO container-compatible or not ISO container-compatible. The outer barrel must be designed with these dimensions. The inner barrel to be inserted into this outer barrel is also to be manufactured in accordance with the standards, namely in accordance with the same DIN standard 6643 with reduced dimensions.

Bei der Herstellung dieses doppelwandigen Stahlfasses wird das aus dem Behältermantel 4 und dem Oberboden 5 sowie dem Unterboden 6 bestehende Innenfaß komplett hergestellt. Beim Außenfaß wird zunächst an den äußeren Faßmantel 1 der Unterboden 3 angefalzt. Der Oberboden 2 des äußeren Fasses wird auf den Oberboden 5 des inneren Fasses aufgelgt, wobei die Verbindungsflansche 17 durch die Faßspunde von innen her durchgesteckt werden und hierbei der umlaufende Rand 25 an der Innenseite des Oberbodens 5 anliegt. Der Flansch wird dann an seinem oberen Rand im Bereich einer Umbördelung 22 umgelegt, wodurch die beiden Böden 2, 5 miteinander verbunden sind. Daran anschließend wird das Innenfaß in das Außenfaß eingestellt und der Oberboden 2 mit dem äußeren Faßmantel 1 im Bereich der Falzverbindung 7 zusammengefalzt.In the manufacture of this double-walled steel barrel, the inner barrel consisting of the container jacket 4 and the top shelf 5 and the bottom shelf 6 is completely manufactured. In the outer barrel, the underbody 3 is first folded onto the outer barrel jacket 1. The top shelf 2 of the outer barrel is placed on the top shelf 5 of the inner barrel, the connecting flanges 17 being inserted from the inside through the barrel bung and the circumferential one Edge 25 abuts the inside of the top 5. The flange is then folded over at its upper edge in the region of a flange 22, as a result of which the two trays 2, 5 are connected to one another. Then the inner drum is inserted into the outer drum and the top panel 2 is folded together with the outer drum jacket 1 in the area of the fold connection 7.

Bei der in den Figuren 4 und 5 dargestellten Ausführungsform wird entsprechend verfahren, wobei dort der Oberboden 2 mit dem Boden 5 im Bereich der Faßspundlöcher 11, 12 verschweißt wird, ehe der Boden 2 auf den äußeren Faßmantel 1 aufgefalzt wird.In the embodiment shown in FIGS. 4 and 5, the procedure is similar, the upper floor 2 being welded to the floor 5 in the region of the barrel bung holes 11, 12 before the floor 2 is crimped onto the outer barrel jacket 1.
