DE4325807A1 - Tank for transporting or storing hazardous materials - Google Patents

Abstract

A tank for transporting and/or storing dangerous substances, and particularly petrol, oil, etc. which pollute the environment (e.g. liquefied gases) if they escape, has a rounded closed body fitted with filling and emptying gear. It contains an internal glass fibre system to confine movements of the tank contents. The fibres used have been treated to render them hydrophobic and with a binder which does not react with the contents. The glass fibres are coated with an epoxy and/or methylene resin, hardener, methyl polysiloxane or silicone methyl resin and dust-laying agent binder which is sprayed on either in the form of its individual components or as an emulsion produced from them. The binder can also contain polyester resin and starch.

Description

The invention relates to a tank container for the trans port and / or storage of hazardous substances, esp special of petrol, oil and. a., the environment ge dangerous goods as well as liquefied petroleum gas, with an all-round ge closed body, which over filling and removal devices and the movements of the dangerous goods inside the container damping inner structure made of glass fibers adds the glass fiber with a water repellent and a binder that does not react with the dangerous goods is coated according to a patent (patent application P 42 22 450.0).

Containers and especially transported on vehicles Container, d. H. So tanks have been around since 1976 statutory provisions are marked with warning signs, if they contain dangerous goods. Essential The reason for this is that such tankers at one Accident or if the container leaks petrol or oil Release similar substances into the environment and thereby the environment and especially endanger the groundwater considerably. Especially because of the considerable transpor in such tankers quantities are therefore special safety measures conducive. Tank vehicles with a capacity of 35,000 l and more must also drive on roads that are not in perfect condition are or are not even attached, the device Contents of the container, especially if the container is not is filled to 100% in fluctuations affecting driving safety can significantly affect the vehicle. Around To prevent rocking movements, it is known to do so Tank containers with internals, so-called baffles to ver see. The disadvantage of these baffles is that they ent neither have to be arranged in a very short distance or but then only have an insufficient effect. About that they can also prevent the leakage of the environment  In no way prevent good things.

A tank container is known from the main application, at the whole or part of the interior of the container at high temperature blown glass wool is filled, this Glass wool coated with starch and silicone to match the This way is not affected by the dangerous goods To create latticework. This latticework is additional by means of supports inserted into the interior of the container amplified, which at the same time also the insertion and Pulling out the latticework from the inside of the container should lighten. The disadvantage of this training is that in particular the internals the curb weight of such Influence the tank container afterwards, on the other hand are necessary to function together with the glass wool to take over the baffles. Another disadvantage is from that the starch coated glass wool due to the organic components have a limited service life.

The invention is based on the object, the empty weight in the known, with appropriately treated and trained glass wool filled tank containers to reduce and to improve the service life of the "inner scaffold".

The object is achieved in that the Glass fibers with an epoxy and / or methylon resin, hardener, Methyl polysiloxane or silicone methyl resin and dust binder existing binders are coated, which in single comm components or in the form of a previously prepared emulsion the fibers are sprayed on. Just like epoxy resin is suitable Methylon resin optimal for connecting and coating the glass fibers, whereby methylon resin through a very good adhesion ability to distinguish glass. Both alone and in A mixture with epoxy resin is used here as a binder, which results in a very beneficial fiberglass mesh fabric that optimal for the integration of the filled dangerous goods  is suitable. Here it is possible, as described, for oil or the like Release and transport environmentally hazardous goods to store, the tank container optimally also for Transport and storage of LPG u. Ä. Fabrics suitable. Even if such tank containers are damaged by accidents environmental hazard is excluded because the glass fiber mesh "holds" the filled substances and make sure that the oxygen cannot get in, so that explosions are impossible. Because that as a bindemite methylon resin as well as epoxy resin accordingly stable inner framework for such containers result, can u on the usual Schwappbleche. a. waived become. In addition to the single use of epoxy and methylon Resin can also be used in a mixture, especially methylon can be optimally used for such mixtures. Thereby the number of receptors can be increased significantly, so that the respective circumstances and also to be transported dangerous substances may be particularly suitable Offer "tank interior". Especially when transporting Liquefied petroleum gas and other liquids with a small upper Such tank containers are particularly suitable for surface tension good because the filled material through the adsorber or the filled-in fiberglass grille optimally integrated and firm is held so that it is only emptied accordingly can be, for example, by compressed air or a natural gas is pushed in.

By such a binder, which corresponds to the appropriate preparation is still optimized in its effect, it is ensured that the corresponding scaffold made of glass fa high stability with sufficient flexibility points. In addition, such a framework made of glass fa have a practically unlimited lifespan. Due to the favorable stability, it is possible to install the internals, d. H. that is, the individual ones running in the longitudinal and transverse directions To reduce supports or even to do without them entirely, because  now the correspondingly prepared and processed Glass fibers can fulfill this task themselves. The Vorbe Preparation of the binder in the form of the emulsion to be sprayed on ensures an even coating of the individual fibers, which in turn benefits stability, since the individual Glass fibers pressed together in the processing area and combined into a stable structure.

After a further embodiment of the invention is pre see that the glass fibers with an epoxy and / or methylon resin or polyester resin or the same or similar acting Best plastic, hardener, dust binder and silicone resin existing binders are coated. This training of Binder ultimately says that appropriate synthetic resins with the corresponding effects and properties of the epoxy Resin the properties of the filling described above secure the tank container, so that it can alternatively also in Mix can be used depending on the expediency and price can. The dust binder as such is only used during the Manufacturing process of the glass fibers needed to make the Ent to effectively prevent the formation of dust.

After the main application, it is envisaged that the Glasfa are coated with a binder consisting of a Emulsion of silicone resin, starch, synthetic resin (epoxy resin), Silane and dust binding agent (MULLREX) exists. Such aqueous emulsion can, as already mentioned, some of the similar Lich acting components or a ent speaking mixture, depending on how this results from cost or other reasons as expedient. Silane serves on the inorganic and organic loading components of the emulsion to act as a catalyst.

A particularly advantageous processing and therefore also a setup of the tank container is possible in that surround the glass fibers in packets with a thin glass fleece  and are filled into the container as packages. The single ones Packages are put together and then in the container inserted in such a way that they serve the entire container Fill in moderately. The glass fleece not only forms an appropriate wrapping of the individual glass fibers, but also a scaffolding, especially if the individual non-woven fabrics assigned to packages by adhesive or the like are connected. The glass fleece as such provides for the filled in dangerous goods do not represent a hindrance since it is just as permeable to liquids as the individual packages. It should be noted that advantageously by the glass fibers in the event of damage, d. H. in an accident Dangerous goods cannot escape because of the glass fibers and that Glass fleece has an adsorbing effect on the dangerous goods. Even if a fire occurs, it can cause an explosion do not come because the leakage of the dangerous goods like described is prevented. This is significant for Such tank containers because the dangerous goods by the special their training not only no longer occurs in large quantities can, but also stored explosion-proof is.

Further stabilization of the "inner scaffold" is possible Lich, by completely or partially the internals by a thin nes, fixed to the inside wall of the container and with the preferably bundled glass fibers connected glass fleece or glass fabric are replaced. The glass fleece, which can also be stretched accordingly, takes over the function of the internals, but not then more the possibility is given to the entire inner life push, but rather is the setting of the fleece on the inner wall of the container is required in sections. Weight reduction is advantageous, however, because this glass fleece is characterized by a particularly low weight and also has the advantage that the dangerous goods without can pass further through this glass fleece wall. The  Glass fleece or a corresponding glass fabric can last Lich even used as a baffle in tanker vehicles are, these glass fleeces or glass fabric even the Have the advantage that they have a certain flexibility, without the risk of tearing. Usually These glass fleeces or glass fabrics are intended for the internals or partially replace and thus the inserted packages made of glass fibers or the glass wool so that a even filling and emptying of the tank container possible is.

Particularly advantageously shaped and trained packages can be achieved and predetermined according to the invention that the bulk density of the glass to be packaged fibers after spraying with the binder over a endless link belt adjustable in pressure is. This endless link belt expresses the informal cotton Glass fibers together so that appropriate packages or also result in roles. Through laterally running cutting equipment edges are cut straight so that then read exactly predetermined shapes for the packages sen. The endless link belt is adjustable so that it can also be used different ge and the respective purpose optimal sufficient packages can be produced.

It was pointed out earlier that the use of epoxy resin u. Resins the service life the fiberglass mats or packages advantageously extend sen. Nevertheless, the Tankbe will be necessary at some point replace the glass fiber filling and then dispose of it. This is easily possible according to the invention by the Packages and thus the coated glass fibers to 850 to Can be heated up to 1000 ° and brought into the glass melt forms are. Possibly. still adhering dangerous goods components are burned, so that a fairly clean and without Problems of reusable or disposable glass mass  results.

Seen overall, the epoxy resin and the remaining components are a stable fiberglass structure, what advantageous partly or even entirely from recycled material can exist if the glass fibers with 6 to 9 wt .-% epoxy Resin, 0.5 to 4 wt .-% silicone resin and as known with dust small amounts of binder are coated. Because of the Epoxy resin in the upper limit corresponding or approximate Quantity it is possible to envelop and close the glass fibers stabilize that Recy cling material can be processed.

Depending on the dangerous goods used, the density of the material can be adjusted, for which the invention provides that the glass fibers combined into mats or packages are packed with a bulk density of 22 to 110 kg / m ³ . This bulk density can be influenced by the manufacturing process so that precise bulk densities are specified, although it is sufficient for general transport if a standard bulk density is used.

Where, for example, liquid gas is transported and ge should be stored, it may be appropriate, even inside the tanker, or the container glass fiber lattice bodies have different bulk densities admit, especially for LPG, that the cavity of the container from the outside in with layers decreasing bulk density is filled. Outside So a particularly dense mat is given, which is the one oxygen penetration much more difficult and care bears that problematic situations even in the event of accidents remain excluded.

The invention is characterized in particular by that a tank container is created, which is a cheap empty  Has weight, so that the amount of filling is correspondingly high is what is achieved in that largely on internals is dispensed with by the glass wool or the Glass fiber material is stabilized. It also gets in shape the epoxy resin uses a material that has a high stand saves time of such tank containers. The inorganic mate rial is neither through the filled dangerous goods nor through other circumstances impaired, so that usually stand times to be reached are those of the actual tank correspond to. The invention is advantageous appropriate tank containers also for the transport of liquefied gas because this material is also safely stored and trans can be ported.

Further details and advantages of the invention counter stand out from the following description of the associated drawing, in which a preferred embodiment play with the necessary details and parts is shown.

Show it:

Fig. 1 a tank container in side view;

Fig. 2 shows a section through the tank container,

Fig. 3 is a schematic representation of a group consisting of packets filling the Tankbe hälters,

Fig. 4 shows a section through a container filled with glass fiber material and

Fig. 5 shows a section through a conventional tank vehicle with internals.

Fig. 1 shows a tank container 1 in side view, which here consists of a tubular base body, to the head-side head plates 23 , 24 are attached, in this way with the round body 22 together to give a stable tank container 1 .

This tank container 1 is, as mentioned, closed all around, the container outer wall 7 only being filled by the loading device 8 and the removal device 9 . The dangerous goods are filled into the tank container 1 via the filling device 8 and correspondingly sucked out again by the removal device 9 or else pushed out again by compressed air which can also be introduced via the filling device 8 .

The container interior 10 is completely filled in the embodiment shown in FIG. 2 ersichtli che up to the container inner wall 11 glass wool 12 . This glass wool 12 can be additionally stabilized by fittings 14 , 17 not shown here in detail in the form of supports 16 , in order to prevent sliding back and forth and, at the same time, to facilitate insertion into the interior of the container 10 . For details, Fig. 5 shows.

The embodiment according to FIG. 2 shows a uniform filling from the container interior 10 with the glass wool 11, which is composed of individual glass fibers 28, 29, the arbitrary or prescribed by the manufacturing method ge are unpacked. These glass fibers 28 , 29 are coated according to FIG. 2 with a respective binding agent tel 30 , 31 , 32 . The binder 30 consists essentially of epoxy resin and. Ä. acting or composite resins and the binder 32 made of epoxy resin and starch, depending on the application, the proportion of starch can go to 100%.

While it has been placed into the glass wool in FIG. 2 in the container in 12 nenraum or pushed in, the formation of 3 looks like Fig. Before a packet-wise arrangement. The packages 34 , 35 are shaped so that a layer on top of each other is possible. Few shapes are specified for the individual packages 34 , 35 , so that even with round bodies according to FIGS . 1 and 2, relatively few sizes are sufficient.

The individual packages 34 , 35 are surrounded according to FIG. 3 with a glass fleece 36 , which specifies and ensures in the form of the individual packages 34 , 35 and at the same time gives the possibility of also connecting the individual packages 34 , 35 to one another, for example so to secure the layers accordingly. It is also conceivable, however, to largely reduce the internals 14 shown in FIG. 5 with the aid of the glass fleece 36 or even to dispense entirely with such stable and scissor internals. Corresponding internals made of glass fleece 36 can also be used in the embodiment according to FIG. 4 in order to secure the individual packages 34 , 35 or to connect them in some way. When in Fig. 4 ersichtli chen training is a container which is coated by an insulating material 25, a temperaturmäßi ge influencing the filled in the container to prevent dangers good.

Fig. 5 has been further already mentioned forward. In the training shown here, only one centrally arranged vertical support 16 and horizontal support 17 are provided as internals 14 , the vertical support 16 but also the horizontal support 17 being supported via base plates 20 against the inner wall 11 of the container.

In addition to or instead of the supports 16, 17 , walls 38 , 39 made of glass fleece 36 can be used here, whereby these walls 38 , 39 are used, these walls 38 , 39 each being effectively fixed on the inner wall 11 of the container or else only are given to the individual again. The definition of the walls 38 , 39 only on the individual packages 34 , 36 provides an advantageous stabilization and also enables the corresponding prefabricated "filling" to be simply pushed into or pulled out of the tank container, which can still be improved, that horizontal walls 40 are also used.

According to Fig. 5 of glass wool a skeleton of glass mat may ultimately from this yes relatively flexi ble material but also in a non-packet array 12 36 determined who that passes the one of the vertical glass fleece walls 38, 39 and diagonal glass fleece walls 41. Indicates here that a proper linkage of the walls 38 , 39 and 41 or 40 is possible by means of appropriate clips 42 .

All mentioned features, including those of the drawings alone to be extracted, alone and in combination, are invented considered essential.
