Storage containers for liquids, in particular heating oil

The invention relates to a storage container in a wide variety of geometric shapes for liquids, such as acids, milk, wine, especially fuel oil and consists in that the inner surface of the storage container with an injected double-walled inner lining made of oil- or chemically and mechanically resistant Plastic is provided with at least two layers, with the one applied directly to the container Layer is porous, while a solid layer can be applied to the porous layer.

It is known to provide storage containers, in particular fuel oil containers, with corrosion protection, with the tanks on the inside be sprayed with paints or resins in the so-called thin coating or with covers made of elastic Foils are lined. There are also built-in

Systems known to use the synthetic resin panels in the lining, which then in the tank by resin or adhesive be glued together to form an inner container. It is also known that such containers can also be sprayed be provided with a massive thick coating.

The storage container according to the invention is characterized by a extremely economical manufacturability, with the Advantages of the known inner linings, in particular that lined with an envelope made of an elastic film Tanks are preserved.

A design according to the invention provides that the porous Layer is criss-crossed by fine channels.

One can proceed according to the invention so that in the porous layer, a probe tube is injected, which is led out liquid-tight and airtight at the dome neck.

After a further proposal according to the invention goes so that the solid layer is pulled up to the dome cover flange.

Finally, there is another design according to the invention suggest that the entire outer surface of the container is provided with an outer layer corresponding to the solid layer.

It has now also been shown that one, in further advantageous Embodiment of the present invention, the inner surfaces of the storage container with a liner Oil or chemically and mechanically resistant, flexible plastic parts can be provided that can be glued together and the side facing the inner surface of the storage container may have a protruding or backward

have jumping profiling. It is advantageous to to make the profiling hard and dimensionally stable, because you are then between the inner wall of the container and gaps between the plastic parts placed on it.

Another embodiment of the invention also exists in that the plastic parts that can be placed on the inner surface of the shell of the container as a strip, possibly with a Opening for the dome neck, while an in the dome neck suitable sleeve with puddle can be inserted into the dome neck. In the same way can be arched Plastic base placed on the inside of the container base be with the plastic bottom on the the container bottom facing side have a protruding or receding profiling.

According to the invention, a closed inner tank can be made from the plastic parts in the manner described above Form from plastic, which is connected by gluing or potting.

Another design according to the invention provides that the resulting from the profiling gaps between the wall of the container and the plastic parts with a Liquid, possibly a corrosion-preventing liquid, are filled.

Finally, according to a further proposal of the invention, you can proceed so that the spaces between the wall of the container and the closed inner tank made of plastic parts are connected to a leak warning device based on vacuum or liquid.

If one uses storage containers according to the proposal · of the present Invention, then the object is to prevent the inner tank from becoming defective and to indicate leaks, advantageously solved.

You can namely, according to the proposal of the invention, in normal and single-walled, mostly made of sheet metal Bring in storage containers either plastic layers or use prefabricated plastic parts and in Glue the container together. Because these plastic parts are flexible they can be inserted into the finished container at a later date. Because through the profiles on the back the plastic parts a space between this so formed plastic wall and the inner wall of the sheet metal container arises, air or a liquid can circulate there unhindered. This has there is also the particular advantage of having a vacuum or liquid-based leak warning device with this space connect to. If you then still use it as a leakage fluid a corrosion-preventing liquid is used as a further additional protection against corrosion Given to storage containers made from sheet metal.

Since one finally provides an inner container made of plastic within the sheet metal container, which easily Can be subsequently produced in a sheet metal container, one can then use corrosion-inducing containers in such containers Store liquids such as acids and alkalis; but you can also buy food, wine and the like pour more into these containers.

Further features of the invention emerge from the following description of an exemplary embodiment in FIG

Connection with the drawings and claims. It show, in schematic sketches,

Plastic parts,

FIG. 10 shows a section through one according to the invention lined storage containers,

FIG. 11 a view, on a reduced scale, such a storage container.

The storage container 1 shown in Figure 1 is with a Cathedral 2 provided. The inner surface of the I ^ erbehälters 1 is with a porous layer 3 is provided on which a solid layer is applied. The layers 3 »^ are made by spraying

-G-

applied to the inner surface of the storage container 1 and consist of a chemically and mechanically resistant Plastic, such as glass fiber reinforced UPE resins. The solid layer 4 can be led out as far as the dome cover flange 6, whereby they forms a flat sealing surface for the dome cover to compensate for a welding distortion.

Such containers are generally provided with a leak warning system, for receiving a leak warning probe a probe tube is provided. In the present invention, a probe tube 5 is injected with the between the jacket of the storage container 1 and the solid layer 4 'arranged and runs in the porous layer 3. The The probe tube 5 is liquid-tight and airtight on the dome neck 2 led out. Instead of a leak warning probe, a vacuum device can also be used, which then removes the porous Keeps layer 3 under vacuum and can indicate a leak with the help of known warning systems. After applying the porous layer 3 and before it hardens, this can be provided with fine channels, which are created by that you can use a roller that carries protruding rings in any way and in different directions across the porous Shift 3 runs. Through the feim η channels, in the event of a leak the liquid seep through the porous material over a short path, whereby the flow resistance is created through these fine channels is significantly reduced, so that the liquid can collect in the bottom of the tank and a leak warning device in action can move.

In order to protect the storage tank 1 from the outside against corrosion, one of the solid layer 4 corresponding outer layer 7 can be applied to the outer surface of the container 1, which up to is raised to the dome cover support and thus with security

separates the entire outer surface of the container from the surrounding medium.

Another design according to the invention is shown in FIGS. 10 and 11, where in a storage container 1 from Sheet metal or similar material, an inner tank 8 made of plastic parts used there, which together glued or potted, is shown.

In such a container 1 plastic parts 9 » which are flexible, used and which are advantageous on the side 12, with which they are on the inside of the bearing ' container 1 come to rest, are provided with a profile 13. This creates coherent spaces between this inner tank S made of plastic and the inside of the storage container 1. In these spaces air or a leakage liquid filled in there can circulate. In this way it is also possible to connect a corresponding leak warning device 19 to these spaces. There are also strips 10 provided, which have an opening 14 corresponding to the dome neck; otherwise these strips 10 are designed in the same way like the stripes 9- In the dome neck itself there is one Sleeve 15 made of plastic used, which is also on their the side facing the metal is equipped with a profiling 13 is. The sleeve has a flange 16 which can be connected to the dome cover flange 6.

Plastic bottoms 11 are inserted into the bottoms 17 of the container, which are also provided with a profile 13 on the side facing the inside of the container bottoms. If you have all of these plastic parts introduced into the interior of a storage container 1 by gluing or potting connects with each other, one has the already mentioned sealed inner tank 8 available.
