- Such a material unlike metals, holds aggressive liquids such as e.g. in the container stored acids, stood.
- the flange has an opening through which a connection to the conductor element can be made and which is easy to seal. Through this opening, for example, can lead to a electrically connected to the conductor element threaded piece on which a clamp of a drainage cable can be secured by one or more nuts.
- the opening is sealed by a ring seal surrounding the threaded pin. Since the threaded piece can be sealed against the outlet opening of the container, it does not come into contact with an aggressive liquid stored in the container and may be made of metal.

- a part of the intermediate conductor element can be cut away.
- a lost plug connection can be provided to the part of the end wall to be cut out to form the opening.
- a staggered to the outlet opening of the container arranged pin-like conductor element may be provided which is guided through a bore penetrating the flange and the container wall.
- the arranged between the flange and the container wall portion of the conductor element is very short.
- This pin-like conductor element may be formed by a screw which engages behind the container wall with its head and preferably rotatably in the container wall is retractable.

- the sleeve 9 engages in a plug-in hole 14, which is radially offset from the pipe section 1 of the drain fitting formed on the flange 3.
- the plug-in hole 14 is provided in a rib-less region, which has a further plug-in hole 15 for receiving the pin 13.
- This plug-in hole 15 is formed in an end wall 16 terminating the pipe section 1, into which, after connecting the flange 3 to the container wall, a drain opening indicated by a dashed line in FIG. 4 is cut.

- the conductor element 6 Before welding the drain fitting with the container, the conductor element 6 is fitted under engagement of the pins 10,13 in the holes 14,15 on the drain fitting. The position of the conductor element relative to the drain fitting is thus determined. Instead of through the connectors or in addition, the conductor element could be connected to the drain fitting by welding or / and gluing.
- a cut bore is formed through the pipe section 1 to form the drain opening 17, wherein in addition to the end wall 10 and the conductor element 6 and the container wall is cut.

- the drain opening 17b adjoins the handle part 8b only in one point or one line.
- a stem part 8c of a conductor element 6c also adjoins only one point or a line at a drain opening 17c. Radially offset from the discharge opening 17c, a projection 21c projects from the stem part 8c.
- the flange need not be integrally connected to the rest of the drain fitting, but only with a nozzle to which the rest of the drain fitting, preferably by screwing, can be connected.
Description
Die Erfindung betrifft einen Behälter, insbesondere einen Paletteninnenbehälter, mit einer Ablaufarmatur, die an eine Auslassöffnung in der Behälterwand angeschlossen und über einen Flansch mit der Behälterwand verbunden ist, sowie mit einem Leiterelement zur Ableitung elektrischer Ladungen aus dem Behälter.The invention relates to a container, in particular a pallet inner container, with a drain fitting which is connected to an outlet opening in the container wall and connected via a flange to the container wall, and with a conductor element for discharging electrical charges from the container.
Es sind solche Behälter bekannt, dessen Leiterelement durch die Kunststoffwand des Behälters oder eines Rohrstücks der Ablaufarmatur hindurch geführt ist und in den Behälter hineinragt.There are known such containers whose conductor element is guided through the plastic wall of the container or a pipe section of the drain fitting and projects into the container.
Durch die vorliegende Erfindung wird ein neuer solcher Behälter geschaffen, der dadurch gekennzeichnet ist, dass das Leiterelement wenigstens ein Teilstück aufweist, das zwischen dem Flansch und der Behälterwand angeordnet ist.By the present invention, a new such container is provided, which is characterized in that the conductor element comprises at least a portion which is arranged between the flange and the container wall.
Vorteilhaft eröffnet diese Erfindungslösung die Möglichkeit, ein Ladungen ableitendes Leiterelement ohne zusätzliche Durchbrüche in der Behälterwand oder der Ablaufarmatur am Behälter anzubringen.Advantageously, this invention solution opens up the possibility of attaching a charge dissipating conductor element without additional openings in the container wall or the drain fitting on the container.
In der bevorzugten Ausführungsform der Erfindung besteht das Leiterelement aus einem Kunststoff, in welchen ein elektrisch leitendes Material, vorzugsweise Kohlenstoff, eingebettet ist. Ein solches Material hält im Unterschied zu Metallen aggressiven Flüssigkeiten, wie z.B. im Behälter aufbewahrten Säuren, stand.In the preferred embodiment of the invention, the conductor element consists of a plastic, in which an electrically conductive material, preferably carbon, is embedded. Such a material, unlike metals, holds aggressive liquids such as e.g. in the container stored acids, stood.
Während es denkbar ist, das Leiterelement aus seiner Einbettung zwischen Flansch und Behälterwand seitlich herauszuführen, weist in einer bevorzugten Ausführungsform der Erfindung der Flansch eine Öffnung auf, durch die hindurch eine Anschlussverbindung zu dem Leiterelement hergestellt werden kann und die leicht abzudichten ist. Durch diese Öffnung lässt sich z.B. ein mit dem Leiterelement elektrisch verbundenes Gewindestück führen, an dem durch eine oder mehrere Muttern eine Schelle eines Ableitkabels befestigt werden kann. Vorzugsweise ist die Öffnung durch eine den Gewindestift umgebende Ringdichtung abgedichtet. Da das Gewindestück gegen die Auslassöffnung des Behälters abgedichtet sein kann, kommt es mit einer im Behälter aufbewahrten aggressiven Flüssigkeit nicht in Kontakt und kann aus Metall bestehen. Das Gewindestück kann durch eine Schraube mit einem drehfest in das Leiterelement versenkbaren Kopf gebildet sein.While it is conceivable to lead the conductor element laterally out of its embedding between flange and container wall, in a preferred embodiment According to the invention, the flange has an opening through which a connection to the conductor element can be made and which is easy to seal. Through this opening, for example, can lead to a electrically connected to the conductor element threaded piece on which a clamp of a drainage cable can be secured by one or more nuts. Preferably, the opening is sealed by a ring seal surrounding the threaded pin. Since the threaded piece can be sealed against the outlet opening of the container, it does not come into contact with an aggressive liquid stored in the container and may be made of metal. The threaded piece can be formed by a screw with a rotatably retractable into the conductor element head.
In der bevorzugten Ausführungsform der Erfindung ist das Teilstück des Leiterelements vollständig durch eine Schweißverbindung zwischen dem Flansch und der Behälterwand umschlossen, wodurch die Auslassöffnung rundum abgedichtet ist.In the preferred embodiment of the invention, the portion of the conductor element is completely enclosed by a welded connection between the flange and the container wall, whereby the outlet opening is completely sealed.
Das Verbinden von Flansch und Behälterwand kann erleichtert werden, indem im Flansch oder/und der Behälterwand eine an den Umriß des Leiterelementteilstücks angepasste Sitzausnehmung gebildet ist. Vorteilhaft lässt sich so verhindern, dass der Flansch beim Verbinden mit der Behälterwand durch das zwischenliegende Leiterelement in unerwünschter Weise verformt wird.The connection of the flange and the container wall can be facilitated by forming a seat recess adapted to the contour of the conductor element section in the flange and / or the container wall. Advantageously, it is thus possible to prevent the flange from being undesirably deformed when it is connected to the container wall by the intermediate conductor element.
Zweckmäßig sind Einrichtungen vorgesehen, die es ermöglichen, das Leiterelement vor der Verbindung von Flansch und Behälterwand auf die Ablaufarmatur aufzustecken. Beim Verbinden von Flansch und Behälterwand behält das Leiterelement dann genau die erforderliche Position relativ zur Ablaufarmatur bei.Appropriately, facilities are provided which make it possible aufzustecken the conductor element before the connection of flange and container wall to the drain fitting. When connecting flange and container wall, the conductor element then retains exactly the required position relative to the drain fitting.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist das Leiterelement an wenigstens einem Randpunkt bündig zum Rand der Auslassöffnung und/oder einer Ablauföffnung in einer in den Flansch übergehenden Stirnwand des Rohrstücks.In a further advantageous embodiment of the invention, the conductor element is at least one edge point flush with the edge of the outlet opening and / or a drain opening in a transition into the flange end wall of the pipe section.
Das Leiterelement kann z.B. einen Ring aufweisen, dessen gesamter Innenrand bündig zu den genannten Öffnungsrändern ist. Anstelle eines Vollrings lässt sich auch ein Teilring verwenden.The conductor element may e.g. have a ring whose entire inner edge is flush with said opening edges. Instead of a solid ring can also use a partial ring.
In weiterer Ausgestaltung der Erfindung weist das Leiterelement einen Ansatz auf, welcher in ein mit dem Flansch verbundenes Rohrstück der Ablaufarmatur oder in den Behälter hineinragt. Zweckmäßig ist dieser Ansatz radial versetzt zu einer Öffnung in einer in den Flansch übergehenden Stirnwand des Rohrstücks angeordnet. In diesem Fall lässt sich die Auslassöffnung nach der Verbindung von Flansch und Behälterwand herstellen, indem durch das Rohrstück hindurch eine Schnittausbohrung zunächst der Stirnwand und dann der Behälterwand erfolgt. Dabei kann auch ein Teil des zwischenliegenden Leiterelements weggeschnitten werden. Insbesondere kann eine verlorene Steckverbindung zu dem zur Bildung der Öffnung auszuschneidenden Teil der Stirnwand vorgesehen sein.In a further embodiment of the invention, the conductor element on a lug, which projects into a connected to the flange pipe section of the drain fitting or into the container. Suitably, this approach is radially offset from an opening arranged in a transition into the flange end wall of the pipe section. In this case, the outlet opening after the connection of the flange and the container wall can be produced by a cut-through bore first of the end wall and then the container wall through the pipe section. In this case, a part of the intermediate conductor element can be cut away. In particular, a lost plug connection can be provided to the part of the end wall to be cut out to form the opening.
In einer weiteren Ausführungsform der Erfindung kann ein zu der Auslassöffnung des Behälters versetzt angeordnetes stiftartiges Leiterelement vorgesehen sein, das durch eine den Flansch und die Behälterwand durchdringende Bohrung geführt ist. In diesem Fall ist das sich zwischen dem Flansch und der Behälterwand angeordnete Teilstück des Leiterelements sehr kurz.In a further embodiment of the invention, a staggered to the outlet opening of the container arranged pin-like conductor element may be provided which is guided through a bore penetrating the flange and the container wall. In this case, the arranged between the flange and the container wall portion of the conductor element is very short.
Dieses stiftartige Leiterelement kann durch eine Schraube gebildet sein, die mit ihrem Kopf die Behälterwand hintergreift und vorzugsweise drehfest in der Behälterwand versenkbar ist.This pin-like conductor element may be formed by a screw which engages behind the container wall with its head and preferably rotatably in the container wall is retractable.
