Definitions

• Container for receiving a fluid
• the present invention relates to a container for holding a fluid, comprising a rigid outer shell, which is formed substantially in one piece as a closed container, an insulating layer which is supported on the outer shell surface and at least one inner container, which is supported flat against the insulating layer.
• the transport of goods in containers is becoming increasingly important due to the simple logistics. This also applies to liquids and gases, ie fluids that are transported in so-called tank containers.
• the conventional tank container is constructed so that inside a cuboid frame, which has the standard dimensions of a container, an inner container is attached, which receives the fluid. In many cases it is necessary to keep the fluid at a certain temperature. In these cases, the inner container is covered with an insulating layer.
• the application of the insulating layer is relatively complex and there is always the risk that the insulating layer is damaged during the handling of the container, as it is freely accessible through the interstices of the frame.
• Another disadvantage of the conventional tank container is that the inner container must be made sufficiently stable to accommodate the required loads can. These are in particular the weight of the content and the pressure forces due to the internal pressure. Due to these facts, conventional tank containers are heavy and expensive.
• a tank container which has a thin-walled inner container, which is surrounded on its outer side with an insulating layer.
• the insulating layer takes in addition to the thermal insulation and the task of supporting the inner container, since this alone would not be able to withstand the loads acting on it.
• Such a container solves some of the problems described above and can be particularly easily and material-saving formed.
• it is critical that the insulating layer must derive the supporting forces of the inner container on a frame-shaped outer structure and therefore itself must have a relatively high strength. When choosing the insulating material, therefore, a compromise between insulating effect and mechanical strength must be considered.
• such a container can be produced only with great effort and costly.
• the object of the present invention is to avoid these disadvantages and to provide a container which has a simple structure, is robust and has good insulation properties with low weight. In particular, it should be possible to represent a high filling volume with given external dimensions.
• the insulating layer has inserts made of vacuum insulation panels (VIP).
• VIP vacuum insulation panels
• An essential aspect of the present invention is initially that a standard container can be used as the outer shell. Such containers are available in large numbers, mass-produced inexpensively and extremely robust to handle.
• Another essential aspect of the invention is that the insulating layer can be supported substantially over the entire surface of the outer shell, so that it is mechanically subjected only to a small pressure load. In this way it is possible to select an insulating material which has optimum insulation properties, since the mechanical properties are largely uncritical.
• the insulating layer is protected by the outer shell against mechanical damage, so that the containers are very durable. Depending on the given requirements, a compromise between thermal insulation and volume of the inner container can be discussed in the container according to the invention.
• brackets or the like are provided, which thermally connect the inner container with the outer shell and thus represent thermal bridges that degrade the insulation properties.
• VIPs vacuum insulation panels
• the goal of a large filling volume is achieved in particular by the fact that the insulating layer has inserts made of vacuum insulation panels (VIP).
• VIPs are used extensively when it comes to achieving the highest possible insulation values.
• VIPs consist of a gas- and water-vapor-tight envelope and a filling material housed in the envelope, wherein after evacuation to a negative pressure, the envelope is closed.
• Such vacuum insulation panels are eg in the DE 198 14 271 A, DE 298 09 807 U or DE 298 11 136.5 A.
• silica is pressed as a filler to a plate and then the plate is sealed in a vacuum in a gas and water vapor-tight film.
• Glass fiber, open-cell plastic foams, silicic acid, and degassed polyurethane foam from waste refrigerators have hitherto been known as further fillers for producing VIP. It is also known to fill filler loose in a wrapper and then to evacuate the wrapper. This gives the panel its stability.
• the envelopes may be made of metal foil, plastic films or a combination of such films.
• Important properties of vacuum panels and thus also of their fillers are low thermal conductivity, pressure resistance, thermal resistance and the highest possible heat capacity dimensional stability.
• a particularly simple production and a high-quality insulating layer is achieved when the insulating layer is foamed substantially in situ. Only at the end faces of the inner container, it may be advantageous to keep the inner container freely accessible to make the appropriate maintenance can. In this context, it is particularly advantageous if the required fittings, such as shut-off valves, filling openings, manholes and the like are arranged in this area and thus freely accessible. In order to ensure the insulating effect, appropriate moldings of insulating material are provided to complete the insulating layer here. Alternatively, insulating foils which are foamed in situ may also be provided on the end faces, but these foils are provided inside foils in order to prevent sticking to the doors of the container or to the fittings.
• An alternative solution provides that the entire insulating layer is composed of a plurality of moldings. In this way it is possible to remove the inner container as needed and to use the container that forms the outer shell, otherwise.
• a particular advantage of the solution according to the invention is that even if the inner container is designed as a pressure vessel, it is not necessarily required that it has a circular cross-section. It is quite possible and useful, the inner container in cross section Rectangular shape with rounded corners to avoid dead space and increase the volume accordingly.
• At least one recess for a heat transfer medium is provided in the region of the inner container.
• a heat transfer medium in the interior of the insulating layer, which is sufficient to comply with the temperature limits.
• this heat transfer medium can be ice or dry ice.
• the heat transfer medium can be, for example, hot water or a chemical which has a phase transition in a suitable temperature range.
• a recess may be provided in the insulating layer. It is particularly favorable, however, if the heat transfer medium is arranged in a further flexible container, which is arranged together with the inner container within the insulating layer.
• a closable maintenance opening can be provided in the area of the doors. This makes it possible to provide access to the faucets without having to open the doors themselves. Under certain circumstances, the doors themselves can be permanently closed, for example welded, for the operation of the container, since the operationally required manipulations can be made via the service openings. If necessary, it is also possible to provide further maintenance openings in other places, such as the top of the container.
• FIG. 1 shows a longitudinal section through a container according to the invention with a horizontal sectional plane.
• Figure 2 is a section along line II-II in Fig. 1. and FIG. 3 shows a section along line III-III in FIG. 1.
• the container of Fig. 1 consists of an outer shell 1, which is designed as a standard container. Inside the outer shell 1, an inner container 2 is arranged, which is designed as a thin-walled stainless steel tank depending on the static requirements with a wall thickness of, for example, 0.8 mm.
• the inner container 2 is supported flat on an insulating layer 3, which in turn is supported on the inside of the outer shell 1.
• the insulating layer 3 is largely foamed in one piece in situ and consists of polyurethane with a density of about 30 kg / m 3 to 80 kg / m 3 .
• doors 6 are provided to allow access to the interior. In this area, fittings, such as shut-off valves 4 or a manhole 5 are provided.
• molded parts 7 are provided of insulating material, which complete the insulating layer 3 in this area.
• a cleaning line (CIP line) 8 is used to clean the inner container. 2
• FIG. 11 shows an insert of a vacuum insulation panel (VIP) in the region of a side wall.
• VIP vacuum insulation panel
• inserts can also be provided on the other walls laterally, above and below.
• the inserts extend only in areas of low wall thickness of the insulating layer 3 and may be formed relatively small in circular inner containers 2. This achieves optimum cost efficiency.
• a closable maintenance opening 10 is provided within the door 6, which serves for inspection purposes and for filling and emptying.
• the inner container 2 is formed out of round and has a substantially rectangular shape with rounded corners. In this way, the internal volume can be maximized.
• the present invention makes it possible to present tank containers cost-effective, robust and with optimum insulation.
