Definitions
- the invention relates to a small container according to the preamble of patent claim 1.
- Such Kleincontainer are for example from the DE 200 13 000 U known. They have a container or tank, which is used in a frame with a standardized floor plan, which usually allows the stacking of several small container.
- cooling or heating devices for example consisting of cooling or heating coils, which are controlled by a corresponding control device, are often mounted on the outside of the container.
- an outer sheath is usually provided, which may be attached to the outside of the frame or prefabricated together with the container as an assembly unit and, for example, consists of sheet metal. Insulating means are usually arranged between the container and the outer jacket in order to increase the efficiency of the cooling or heating. Since the outer jacket is exposed to all external influences, in particular also impacts and collisions with other objects, it is understood that it must be made sufficiently stable in order to survive these unscathed.
- the object of the invention is to provide a small container with low production and transport costs. This object is achieved by a small container having the features of patent claim 1.
- the small container according to the invention arranged in a frame, by an insulating layer thermally insulated container, wherein at least one wall of the container is designed as a double wall with an inner wall and an outer wall, wherein the insulating layer between the inner wall and the outer Wall of the double wall is arranged and / or in which the frame has a base frame, a support on the container stacking frame and supports.
- the invention is based on the finding that, with a suitable embodiment, the container wall can assume a plurality of tasks.
- the container wall can accommodate a part of the forces acting on the frame forces when they are introduced into the wall, so that the frame only has to be designed to accommodate lesser loads, what also brings tangible savings in terms of material and weight.
- a heating or cooling device is additionally provided, so that the desired temperature in the small container can be selectively controlled.
- the heating or cooling device on one or more mounted outside the container controls and arranged between the inner wall and the outer wall heating or cooling coils.
- the heating or cooling device may in particular also have one or more heating or cooling circuits.
- control has a stainless steel protective housing and / or is installed in a pressure-sealed housing and the outer wall is penetrated by at least one cable feedthrough, which is preferably liquid-tight and / or gas-tight, since such small container for applications, in which they must be explosion proof, can be used.
- cable bushings made of stainless steel, which are welded circumferentially to the outer wall of the container.
- a particularly cost-effective production of Kleincontainers is possible if the wall of the container is made of segments together, which are welded together.
- segments which are welded together.
- an embodiment with three segments, namely a subfloor, a jacket and a topsoil has proven to be in which the subfloor and the jacket and the topsoil and the jacket are welded together.
- the subfloor can significantly contribute to the complete emptying of the container is possible. This structuring can be achieved very inexpensively and simply by deep drawing.
- a particularly stable arrangement of the container in the frame can be achieved if the inner wall of the container is supported on the base frame. This is advantageously done with round tube feet, the number of which can be limited to three in order to save weight.
- the distance between the inner wall and the outer wall is at least partially not constant in the double wall. This makes it possible in particular to make the shape of the outer wall as simple as possible even in areas where the inner wall is structured. This also contributes to the cost reduction.
- FIG. 1 shows a cross section through a small container 10 according to the invention. It can be seen a frame composed of supports 11, base frame 12 and stack frame 13 and a container 14.
- the wall of the container 14 is composed of three sections, namely an underbody 15, a shell 16 and a top 17.
- the underbody 15, shell 16 and upper floor 17 are each double-walled and each have an inner wall 15.1, 16.1, 17.1 and an outer wall 15.2, 16.2, 17.2.
- an insulating layer 15.3, 16.3, 17.3 is arranged, which is formed in the simplest case as a cavity or space between opposite wall sections.
- the upper floor 17 passes through to fill the container 14, a manhole 18, which is closable with a lid 19.
- the lid 19 may be designed for example as a screw cap or clamping ring cover.
- the underbody 15 passes through a container outlet 20, which can be closed by means of a butterfly valve 21 or a Kugelhans.
- the inner wall 15.1 of the subfloor 15 has at least in sections a slope in the direction of the container outlet 20, which supports the emptying of contents.
- the outer wall 15.2 of the subfloor 15 has a cylindrical embossment 22 which engages with a centering plate 23 provided in the base frame 12 and so ensures the optimal centering of the container 14 in the base frame 12.
- FIG. 1 Next is the sectional view of FIG. 1 to take a Rundrohrfuß 24, which supports the inner wall 15.1 of the subfloor 15 on the base frame 12.
- the area B which is defined by a circular boundary line in FIG. 1 is marked, defines the in FIG. 2a enlarged section of the illustrated FIG. 1 ,
- FIG. 2a shows an enlarged view of the in FIG. 1 With this area, a portion of a support 11, a base frame 12, a bottom 15 and a shell 16 can be seen, with sub-bottom 15 or shell 16 each have an inner wall 15.1 and 16.1 and an outer wall 15.2 or 16.2.
- FIG. 2a can be seen that in the double wall of the subfloor 15 and the shell 16 embedded insulating 15.3 and 16.3, the thickness of which is not constant at least in sections, where "sections not constant" both differences between different areas of the Kleincontainerwandung, eg upper floor 17 and shell 16, as well as differences within a range of the Kleachintainerwandung, eg within the subfloor 15 includes.
- the jacket 16 in general, the jacket 16 a thinner insulation layer 16.3 than the subfloor 15, while on the other hand, a variation of the thickness of the insulating material 15.3 is given at different points of the subfloor 15.
- the area E which is defined by a circular boundary line in FIG. 2a is marked, defines the in FIG. 2b enlarged section of the illustrated FIG. 2a ,
- FIG. 2b shows an enlarged view of the in FIG. 2a area marked with the letter E.
- a transition between an underbody 15 with inner wall 15.1 and outer wall 15.2 and a shell 16 with inner wall 16.1 and outer wall 16.2 can be seen in detail.
- the inner wall 15.1 of the subfloor 15 in the contact region has a higher wall thickness than the inner wall 16.1 of the shell 16. It has been found that such a variation of the wall thickness is tolerable in weld joints as long as the material offset of the components not is more than 50%. This finding is therefore of considerable relevance for weight reduction, as the minimum wall thickness required in the ADR / RID / IMGD Code must be fulfilled in each area of the container wall.
- the subfloor 15 is usually structured, which in particular in the advantageous structuring by deep drawing in certain sections, but not at the edge of the subfloor 15, which is welded to the jacket 16, to a Thickness reduction leads. This edge thus has a greater thickness than is absolutely necessary. Without the provision of a difference in wall thicknesses of underbody 15 and shell 16 in their contact area, therefore, the jacket 16 would have to be made stronger than required, which would entail considerable weight disadvantages.
- FIG. 3a shows an exemplary embodiment the inner wall 15.1 of a subfloor 15 of the small container 10 from FIG. 1 with an outflow opening 300. Especially in the FIG. 3a shaded areas reduces the wall thickness by up to 0.7 mm.
- FIG. 3b is an enlargement of the in FIG. 3a shown area around the outflow opening 300, but now viewed from the outside, to illustrate the areas of reduced wall thickness even clearer.
- FIG. 4 the small container 10 off FIG. 1 with partially removed outer wall 15.2, 16.2, 17.2 and transparent insulation layer 15.3, 16.3, 17.3 shown.
- outer wall 15.2, 16.2, 17.2 and transparent insulation layer 15.3, 16.3, 17.3 in addition to supports 11, base frame 12 stack frame 13 and container 14, only inner walls 15.1, 16.1, 17.1 of the double wall of the container 14.
- an aluminum foil not shown, are arranged, whose reflectivity increases the efficiency of use, especially of heating coils 401 noticeably.
- FIG. 5 shows a side view of the FIG. 1 In this illustration, one recognizes further a protective housing 501, in the interior of which the control for the heating or cooling is arranged.
- FIG. 6 shows the view of FIG. 1 known Kleincontainers 10 obliquely from below.
- the base frame 12 with the centering plate 23, in which the cylindrical embossment 22 is received in the bottom 15, can be particularly well recognized.
- FIG. 7 shows the view of FIG. 1 known Kleincontainers 10 obliquely from above.
- the stack frame 13 engages the edges of the top 17 at least partially the stack frame 13, which has two longitudinal profiles 701, 702 and two transverse profiles 703, 704.

Description
Die Erfindung betrifft einen Kleincontainer gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a small container according to the preamble of patent claim 1.
Derartige Kleincontainer sind beispielsweise aus der
Bei der Konstruktion solcher Kleincontainer sind strenge Regeln zu beachten, die im ADR/RID/IMGD-Code, dort insbesondere im Kapitel 6.5, zusammengefasst sind. Beispielsweise finden sich dort Regelungen, die eine Mindestwanddicke des Behälters, bezogen auf einen Referenzstahl, festschreiben. Dies führt einerseits zu einem hohen Materialaufwand, also hohen Herstellungskosten und andererseits zu einem hohen Gewicht, also hohen Transportkosten.When constructing such small containers, strict rules must be observed, which are summarized in the ADR / RID / IMGD code, in particular in chapter 6.5. For example, there are regulations that specify a minimum wall thickness of the container, based on a reference steel. On the one hand, this leads to a high cost of materials, ie high production costs and on the other hand to a high weight, so high transport costs.
Aufgabe der Erfindung ist es, einen Kleincontainer mit günstigen Herstellungs- und Transportkosten bereitzustellen.
Diese Aufgabe wird gelöst durch einen Kleincontainer mit den Merkmalen des Patentanspruchs 1.The object of the invention is to provide a small container with low production and transport costs.
This object is achieved by a small container having the features of patent claim 1.
Somit weist der erfindungsgemäße Kleincontainer einen in einem Gestell angeordneten, durch eine Isolationsschicht thermisch isolierten Behälter, auf, bei dem mindestens eine Wandung des Behälters als Doppelwandung mit einer inneren Wand und einer äußeren Wand ausgeführt ist, wobei die Isolationsschicht zwischen der inneren Wand und der äußeren Wand der Doppelwandung angeordnet ist und/oder bei dem das Gestell einen Grundrahmen, einen sich auf dem Behälter abstützenden Stapelrahmen und Stützen aufweist.Thus, the small container according to the invention arranged in a frame, by an insulating layer thermally insulated container, wherein at least one wall of the container is designed as a double wall with an inner wall and an outer wall, wherein the insulating layer between the inner wall and the outer Wall of the double wall is arranged and / or in which the frame has a base frame, a support on the container stacking frame and supports.
Der Erfindung liegt die Erkenntnis zu Grunde, dass bei geeigneter Ausgestaltung die Behälterwandung mehrere Aufgaben übernehmen kann.The invention is based on the finding that, with a suitable embodiment, the container wall can assume a plurality of tasks.
So kann einerseits durch Ausführung der Behälterwandung als Doppelwandung mit eingelagerter Isolierschicht bei gleichzeitiger Wahrung der Sicherheitsvorschriften die Funktion des bisher verwendeten separaten Außenmantels übernommen werden, wodurch dieser entfallen kann, was zu erheblicher Material-und Gewichtsersparnis führt.Thus, on the one hand by execution of the container wall as a double wall with embedded insulating layer while maintaining the safety regulations, the function of the previously used separate outer sheath are taken over, so this can be omitted, resulting in significant material and weight savings.
Alternativ oder zusätzlich kann die Behälterwandung einen Teil der auf das Gestell wirkenden Kräfte aufnehmen, wenn diese in die Wandung eingeleitet werden, so dass das Gestell nur noch für die Aufnahme geringerer Lasten ausgelegt sein muss, was ebenfalls spürbare Einsparungen hinsichtlich Material und Gewicht mit sich bringt.Alternatively or additionally, the container wall can accommodate a part of the forces acting on the frame forces when they are introduced into the wall, so that the frame only has to be designed to accommodate lesser loads, what also brings tangible savings in terms of material and weight.
In einer bevorzugten Variante der Erfindung ist zusätzlich eine Heiz- oder Kühlvorrichtung vorgesehen, so dass die gewünschte Temperatur im Kleincontainer gezielt ansteuerbar ist. Dabei weist die Heiz- oder Kühlvorrichtung eine oder mehrere außerhalb des Behälters angebrachte Steuerungen und zwischen der inneren Wand und der äußeren Wand angeordnete Heiz- oder Kühlschlangen auf. Die Heiz- oder Kühlvorrichtung kann insbesondere auch ein oder mehrere Heiz- oder Kühlkreisläufe aufweisen.In a preferred variant of the invention, a heating or cooling device is additionally provided, so that the desired temperature in the small container can be selectively controlled. In this case, the heating or cooling device on one or more mounted outside the container controls and arranged between the inner wall and the outer wall heating or cooling coils. The heating or cooling device may in particular also have one or more heating or cooling circuits.
Besonders vorteilhaft ist weiterhin, wenn die Steuerung ein Edelstahl-Schutzgehäuse aufweist und/oder in einem druckgekapselten Gehäuse eingebaut ist und die äußere Wand von mindestens einer Kabeldurchführung durchsetzt ist, die vorzugsweise flüssigkeitsdicht und/oder gasdicht ausgeführt ist, da derartige Kleincontainer für Anwendungen, in denen sie explosionsgeschützt sein müssen, einsetzbar sind. Besonders geeignet für solche Anwendungen sind Kabeldurchführungen aus Edelstahl, die umlaufend mit der äußeren Wand des Behälters verschweißt sind.Furthermore, it is particularly advantageous if the control has a stainless steel protective housing and / or is installed in a pressure-sealed housing and the outer wall is penetrated by at least one cable feedthrough, which is preferably liquid-tight and / or gas-tight, since such small container for applications, in which they must be explosion proof, can be used. Particularly suitable for such applications are cable bushings made of stainless steel, which are welded circumferentially to the outer wall of the container.
Eine besonders kostengünstige Herstellung des Kleincontainers ist möglich, wenn die Wandung des Behälters aus aus Segmenten zusammen gesetzt ist, die miteinander verschweißt sind. Insbesondere hat sich eine Ausführungsform mit drei Segmenten, nämlich einem Unterboden, einem Mantel und einen Oberboden bewährt, bei der der Unterboden und der Mantel sowie der Oberboden und der Mantel miteinander verschweißt sind.A particularly cost-effective production of Kleincontainers is possible if the wall of the container is made of segments together, which are welded together. In particular, an embodiment with three segments, namely a subfloor, a jacket and a topsoil has proven to be in which the subfloor and the jacket and the topsoil and the jacket are welded together.
Der Unterboden kann durch seine Struktur wesentlich dazu beitragen, dass eine möglichst vollständige Entleerung des Behälters möglich ist. Diese Strukturierung kann sehr kostengünstig und einfach durch Tiefziehen erreicht werden.Due to its structure, the subfloor can significantly contribute to the complete emptying of the container is possible. This structuring can be achieved very inexpensively and simply by deep drawing.
Versieht man weiter den Grundrahmen mit einem Zentrierteller und den Unterboden mit einer zylindrischen Prägung, wird das Zusammensetzen von Gestell und Behälter, das beispielsweise zur Erstmontage oder bei Reparaturen notwendig ist, wesentlich vereinfacht.Providing further the base frame with a centering plate and the bottom plate with a cylindrical embossing, the assembly of rack and container, which is necessary for example for initial assembly or repairs, much easier.
Eine besonders einfache Einleitung von auf das Gestell wirkenden Kräften in den Behälter ist möglich, wenn der Stapelrahmen zumindest in Bereichen, in denen er sich auf dem Behälter abstützt, ein Winkelprofil aufweist.A particularly simple introduction of forces acting on the frame forces in the container is possible if the stacking frame has an angle profile at least in areas in which it is supported on the container.
Weitere Gewichtsvorteile sind erzielbar, wenn die Stützen des Gestells als Hohlprofile gefertigt sind.Further weight advantages can be achieved if the supports of the frame are made as hollow profiles.
Eine besonders stabile Anordnung des Behälters im Gestell kann erreicht werden, wenn die innere Wand des Behälters auf dem Grundrahmen abgestützt ist. Dies geschieht vorteilhafterweise mit Rundrohrfüßen, wobei deren Zahl auf drei beschränkt werden kann, um Gewicht zu sparen.A particularly stable arrangement of the container in the frame can be achieved if the inner wall of the container is supported on the base frame. This is advantageously done with round tube feet, the number of which can be limited to three in order to save weight.
Erfindungsgemäß ist es, wenn bei der Doppelwandung der Abstand zwischen innerer Wand und äußerer Wand zumindest abschnittsweise nicht konstant ist. Dadurch ist es insbesondere möglich, die Form der äußeren Wand auch in solchen Bereichen möglichst einfach zu gestalten, in denen die innere Wand strukturiert ausgeführt ist. Dies trägt ebenfalls zur Kostensenkung bei.According to the invention, when the distance between the inner wall and the outer wall is at least partially not constant in the double wall. This makes it possible in particular to make the shape of the outer wall as simple as possible even in areas where the inner wall is structured. This also contributes to the cost reduction.

Den Oberboden 17 durchsetzt zur Befüllung des Behälters 14 ein Mannloch 18, das mit einem Deckel 19 verschließbar ist. Der Deckel 19 kann beispielsweise als Schraubdeckel oder Spannringdeckel ausgeführt sein. Den Unterboden 15 durchsetzt ein Behälterauslauf 20, der mittels einer Absperrklappe 21 oder eines Kugelhans verschließbar ist. Die innere Wand 15.1 des Unterbodens 15 weist zumindest abschnittsweise ein Gefälle in Richtung auf den Behälterauslauf 20 auf, das die Entleerung von Füllgut unterstützt. Die äußere Wand 15.2 des Unterbodens 15 weist eine zylindrische Prägung 22 auf, die mit einem im Grundrahmen 12 vorgesehen Zentrierteller 23 im Eingriff steht und so die optimale Zentrierung des Behälters 14 im Grundrahmen 12 sicherstellt.The

Insbesondere ist ersichtlich, dass die innere Wand 15.1 des Unterbodens 15 im Kontaktbereich eine höhere Wandstärke aufweist als die innere Wand 16.1 des Mantels 16. Es hat sich gezeigt, dass eine derartige Variation der Wandstärke bei Schweißnahtverbindungen solange tolerabel ist, wie der Materialversatz der Komponenten nicht mehr als 50% beträgt. Diese Erkenntnis ist zur Gewichtsreduktion deshalb von erheblicher Relevanz,.als die im ADR/RID/IMGD-Code geforderte Mindestwandstärke jeweils in jedem Bereich der Behälterwandung erfüllt sein muss. Um eine vollständige Entleerung des Kleincontainers 10 zu fördern, ist der Unterboden 15 in der Regel strukturiert, was insbesondere bei der vorteilhaften Strukturierung durch Tiefziehen in bestimmten Abschnitten, nicht aber an der Kante des Unterbodens 15, die mit dem Mantel 16 verschweißt wird, zu einer Wanddickenreduzierung führt. Diese Kante weist somit eine höhere Dicke als zwingend erforderlich ist auf. Ohne das Vorsehen eines Unterschiedes der Wandstärken von Unterboden 15 und Mantel 16 in ihrem Kontaktbereich müsste somit der Mantel 16 stärker als gefordert ausgeführt werden, was erhebliche Gewichtsnachteile mit sich brächte.In particular, it can be seen that the inner wall 15.1 of the subfloor 15 in the contact region has a higher wall thickness than the inner wall 16.1 of the
