Definitions
- the present invention relates to a device for the safe storage of liquid dangerous goods, comprising an enclosure that is designed to accommodate a storage container for the liquid dangerous goods, the housing having a rear protective wall that is designed to protect a rear side of the storage container, a first lateral Protective wall and a second lateral protective wall that are set up to protect two side walls of the storage container, a front protective wall that is set up to protect a front side of the storage container, and a fluid-permeable platform that is set up as a footprint for the storage container within the device is, includes, and a collection area which is fluidly connected to an interior of the housing.
- the invention relates in particular to the safe storage and the associated fire protection of hazardous liquids, in particular flammable hazardous liquids, such as flammable liquids.
- flammable liquids are to be understood as meaning liquids which can easily ignite in the event of a fire and/or which can be assigned to a hazard class. Chemicals, solvents, highly volatile liquids, fats or the like are to be understood below as examples of flammable liquids.
- IBCs are usually made of plastic and are often encased in a metal frame, cuboid containers with a high capacity, for example with a capacity of 500 to 3000 liters.
- the metal frame can in particular enable the IBCs to be stacked one on top of the other and prevent the plastic of the IBC from bulging when it is filled with liquid, in particular with liquid dangerous goods. They ensure particularly safe and efficient storage, since their cuboid shape makes better use of the available storage space, for example the storage space on a pallet, than steel drums, for example.
- such a storage container should be stored in a corresponding device for safe storage, which includes a housing for the storage container.
- housing is to be understood here in particular as a type of casing which surrounds the storage container when it has been accommodated in the housing.
- the housing includes at least four protective walls that surround the storage container.
- the at least four protective walls comprise a front protective wall, a rear protective wall and a first lateral protective wall and a second lateral protective wall.
- the term front protective wall is to be understood here in particular as meaning a protective wall which is set up to cover a front side of the storage container, on which the outlet opening of the storage container is usually located. The front protective wall should therefore run more or less parallel to the front side of the storage container in the assembled state.
- rear protective wall is to be understood analogously to a protective wall that is set up to cover the rear side of the storage container.
- the rear protective wall should therefore run more or less parallel to the rear of the storage container in the assembled state.
- first lateral protective wall and second lateral protective wall should accordingly be understood to mean the protective walls which are set up to cover the side walls of the storage container. In the assembled state, the first lateral protective wall and the second lateral protective wall should therefore run more or less parallel to the side surfaces of the storage container.
- the front protective wall, the rear protective wall and the first and the second lateral protective wall can be designed in particular as flat, rectangular or square components made of a non-combustible material, for example as metal sheets.
- the enclosure may preferably further include a fluid permeable platform.
- a fluid-permeable platform is to be understood below as a platform that is stable enough to serve as a footprint for the storage container, but at the same time has fluid-permeable properties, so that any hazardous liquid material escaping from the storage container can be drained off through the fluid-permeable platform.
- the fluid-permeable platform can be designed in particular as a grating.
- the rear bulkhead, the first side bulkhead, and the second side bulkhead are connectable to each other and to the fluid-permeable platform to form a first sub-component of the enclosure.
- the device for safe storage also includes a collection area that is fluidly connected to an interior area of the housing.
- An interior area of the housing is to be understood here in particular as the area above the fluid-permeable platform in which the storage container is located and which is surrounded by the front protective wall, the rear protective wall and the first and second lateral protective walls.
- a catchment area is to be understood in particular as an area in which the liquid dangerous goods that have escaped from the storage containers can be collected in order to prevent them from spreading over the entire storage area.
- the capacity for a fluid in the collection area can preferably be chosen such that it can accommodate the contents of at least one storage container and a predetermined quantity of extinguishing fluid without overflowing.
- the predetermined amount of extinguishing fluid can be predetermined in particular on the basis of an amount of extinguishing fluid per unit of time that is dispensed onto the collection area.
- the catchment area can be configured in particular as one or more catchment troughs.
- the definition that the device includes the collection area should be understood broadly.
- a catchment area can be assigned to a number of devices, so that each of these devices encompasses the catchment area or a part of it. Alternatively, however, each device can also have its own catchment area, so there is a one-to-one association between the catchment area and the device.
- a drip tray per level can also be provided, ie any fluid escaping from the devices of one level of the storage arrangement can be directed into the drip tray assigned to the respective level.
- multiple catch basins can also be provided per level, forming multiple catchment areas for the level.
- the collecting pans of a level can be connected to one another in a fluid-conducting manner and thus jointly form a collecting area for the level.
- the collecting pans, which are distributed over the several levels can be connected to one another in a fluid-conducting manner and thus form the collecting area.
- the collecting troughs which are arranged exactly one above the other in the several levels, can also be connected to one another in a fluid-conducting manner, and thus form the collecting area for a specific section of the bearing arrangement.
- each device can have its own collecting pan, with the collecting pans of all devices arranged within a storage arrangement being connected in a fluid-conducting manner and thus being able to form a common collecting area.
- a single drip pan may be provided for all devices within a storage assembly.
- Other arrangements are also conceivable and can be seen from the following description.
- safety measures that ensure that dangerous goods that may escape from the storage containers are not distributed over a large area.
- safety measures can also include fire protection measures, by means of which it is prevented that a fire which may have occurred in the dangerous goods can spread further.
- EP 2 859919 teaches a device for the safe storage of a storage container, in which the storage container is arranged on a fluid-permeable platform on a collecting container.
- the collection container is used here to collect the liquid dangerous goods that have escaped from the storage container and thus to prevent them from spreading.
- EP 2 859 919 teaches arranging a flame arrester between the collection container and the storage container, which serves as protection against flame penetration for the combustible liquid to be discharged in the collection container.
- protective walls are also provided, which are arranged between the storage containers.
- the storage containers are usually arranged in devices specially set up for this purpose.
- These devices include a fire protection tray with a flame arrester for each storage container.
- the fire protection tray serves to collect the dangerous goods that have escaped from the storage containers and to contain them as far as possible.
- the flame arrester also serves to stop contact with a possible source of fire on the storage container.
- such devices can also include one or more splash protection walls, which serve as splash protection.
- a spray protection wall to be arranged on the sides of the storage container and a spray protection wall on the back of the storage container.
- a movable splash guard can also be provided on the front side, i.e. the removal side, of the storage container, which can be folded up if there is actually a fire.
- the object of the present invention is to improve the solutions known from the prior art.
- the front protective wall is set up to be arranged on the storage container in order to, when the storage container is received in the device, together with the rear protective wall, the first lateral protective wall, the second lateral protective wall and the fluid-permeable platform To form housing, wherein the front protective wall comprises a transport receiving means which is adapted to cooperate with a transport means for transporting the storage container.
- the front protective wall should not only be installed after the storage container has been inserted into the device, but should instead be arranged on the storage container beforehand and then transported together with it.
- the housing for the storage container is thus formed by inserting the storage container into the storage arrangement.
- the front protective wall can be designed to be connectable to the first lateral and/or the second lateral protective wall.
- the housing can also be formed without a connection between the front protective wall and the first and the second side protective wall. The front protective wall should therefore already be arranged on the storage container when it is being transported.
- Arranged on the storage container can mean that the front protective wall is attached to the storage container.
- the front protective wall can also be arranged on the storage container in that the attachment is not attached to the storage container itself, but rather to a mounting surface for the storage container, such as a pallet.
- Other ways of arranging the front bulkhead on the storage container can also be devised. It is important that the front protective wall can be moved together with the storage container without changing its position relative to the storage container.
- the front protective wall offers protection on the removal side or front side of the storage container even during transport. On the one hand, this protects against the dangerous goods accidentally escaping onto the transport device, and on the other hand, this prevents the circumstances and dangers of subsequent installation of the front protective wall after it has been arranged within the storage arrangement.
- a further advantage can be seen in the fact that the front protective wall protects the storage container during transport to a certain extent against possible damage by means of transport of the transport device, such as forklift tips of a forklift.
- the front protective wall should have a transport receiving means according to the invention.
- a transport receiving means is to be understood here in particular as a device in the front protective wall which causes the storage container to be transported by conventional transport means, such as forks of a forklift truck, even after the front protective wall has been arranged.
- the transport receiving means should therefore be set up to interact with such transport means in order to transport the storage container.
- transporting should be understood broadly.
- the transporting of the storage container can merely comprise lifting and/or setting down.
- the transport can also include moving and/or rearranging the storage container.
- the term transport includes in particular any movement of the storage container from an original position.
- transporting can serve in particular to arrange the storage container together with the front protective wall in a storage arrangement such as a shelf.
- the enclosure can also include an upper protective wall that is set up to protect an upper side of the transport container after the transport container has been inserted.
- this upper protective wall may comprise an inlet opening for admitting extinguishing fluid from a corresponding extinguishing fluid outlet.
- the device can also include a heat protection element, which can be designed as a heat protection plate, for example.
- the heat protection element can be set up in particular to protect the front protective wall, the rear protective wall, the first and the second lateral protective wall, the fluid-permeable platform and/or other components of the device and parts of the bearing arrangement from heat if an increasing fire event occurs .
- the heat protection element can also be used here to conduct the heat away from a specific area and thus to protect it.
- the thermal protection element may include an opening for admitting extinguishing fluid from a corresponding extinguishing fluid outlet.
- the distance between the storage containers in different levels of the storage arrangement could be increased.
- the distance between storage containers arranged next to one another could also be increased.
- Such an increase in the distance between individual storage containers can be achieved in particular by modifying the storage arrangement.
- the bearing arrangement can be changed so that there is a greater distance than usual between the individual levels.
- the storage arrangement could be changed in such a way that a greater distance is produced between the storage columns, so that with a comparable number of storage containers arranged next to one another, a greater distance between them can be ensured. Due to this larger distance, the heat between the individual storage containers is better distributed and thus reduced. This can reduce the risk of the liquid dangerous goods igniting in other storage containers.
- Another possible heat protection measure can also consist in arranging additional insulating material on the device and/or the bearing arrangement.
- this additional insulating material may comprise an additional damping material, for example. Stone wool should be mentioned at this point as an insulating material that can be used well for this purpose. However, comparable insulation materials are also conceivable for this application.
- the insulating material can be arranged in particular on the bearing arrangement.
- the insulating material can preferably be arranged in a plane of the storage arrangement on which the storage containers can be arranged.
- the insulating material can be arranged in particular on the underside of such a level in such a way that the devices arranged in the underlying level with the storage containers are opposite. This can be done in particular for all levels of the bearing arrangement. If the liquid hazardous material in one of these storage containers ignites, the insulating material can withstand the heat can radiate to the devices above, insulate, i.e. reduce.
- the insulating material can also be arranged on top of the levels of the bearing arrangement, so that the device is placed on top of the insulating material, so to speak.
- the insulating material can also insulate the rising heat and thus protect the storage container, which stands on the insulating material within its device, from the radiant heat.
- the insulating material can furthermore also be arranged on the device, preferably on the top and/or the front of the device, in particular on the upper protective wall and/or the front protective wall. It is also conceivable to arrange the insulating material on the first and/or second lateral and/or rear protective wall. Alternatively or additionally, the insulating material can also be arranged on the fluid-permeable platform.
- an adhesive, foamable seal can also be used as an alternative or in addition to an insulating material.
- a seal from the Promaseal series from the manufacturer Promat should be mentioned at this point as an example of such a foamable seal.
- Such a seal can also preferably be provided, in particular glued, in each level of the storage arrangement on which the storage containers can be arranged.
- the seal can preferably be glued to the underside of the levels.
- gluing the seal on the upper side of the levels is also conceivable, so that the storage containers can be placed on the seal in their device. If the liquid dangerous goods in one of the storage containers ignite, the resulting heat causes the seal to foam up, creating a greater spatial distance and forming a crust of foam, which then acts as a seal against the heat and so the other storage containers in the protects other devices in the bearing assembly.
- the foaming seal can of course also be arranged directly on the device, in particular the front and/or rear and/or the first and/or the second protective wall and/or the fluid-permeable platform of the device and thus provide the heat protection.
- a fire protection paint can also be arranged on the device and/or the bearing arrangement as an alternative or in addition.
- Such fireproof paint is solid at normal temperature like ordinary paint. However, if heat develops, particularly as a result of a fire event, the fire protection paint foams up and thus creates an insulating layer.
- the fire protection paint can be applied in particular to the bearing arrangement.
- the fireproof paint may be provided at the bottom of each level of the storage assembly so as to contain heat rising from a storage container located in the level below and prevent it from reaching the storage containers in the levels above.
- the fireproof paint may be provided at the top of each tier of the storage assembly so that the storage containers in their fixtures can be placed on the fireproof painted tiers.
- It can also be preferred to additionally or alternatively apply the fire protection paint to structurally weak points of the bearing arrangement.
- a structurally weak point of the bearing assembly is understood to mean a point that is significantly less resistant to the effects of high loads and/or high pressure and/or great heat than the rest of the bearing assembly.
- the suspension of the plates of the bearing arrangement forming the individual levels of the bearing arrangement on the bearing columns should be mentioned as an example of such a structurally weak point. This provides additional protection for these structurally weak areas in the event of a fire.
- the fire protection paint can be applied to the device, in particular to the first and/or second lateral protective wall and/or the front protective wall and/or the rear protective wall and/or the fluid-permeable.
- the device can also include at least one deflection surface which is set up to provide at least part of a fluid-conducting connection between the interior area of the housing and the collection area.
- deflection surface should be understood broadly.
- a deflection surface can be understood to mean a surface that is set up to direct the hazardous liquid material that has escaped from the storage container in the direction of the collection area.
- the term deflection surface can also be understood to mean a type of deflection trough which can be set up to first collect the liquid dangerous goods that have escaped from the storage container and then to direct them in the direction of the collection area.
- the deflection surface can have a slope and/or a gradient for this purpose.
- the deflection surface can also have a large number of slopes and/or slopes and/or a conical shape. In some embodiments, these can be designed in such a way that the liquid hazardous material can be directed to a specific point.
- the capacity of the diversion surface for the liquid hazardous material can be selected to be large enough for the diversion surface to act as a buffer for the liquid hazardous material if it suddenly escapes in large quantities from the storage container and the fluid line in the direction of the collection area suddenly absorbs the quantity escaping liquid dangerous goods can no longer afford.
- the device can also include at least one fluid line system, which can be set up to provide at least part of a fluid-conducting connection between the interior area of the housing and the collection area. It can be preferred here that one or the at least one deflection surface has a gradient in the direction of the fluid line system in order to conduct a fluid in the direction of the fluid line system.
- the interior of the housing, into which the liquid dangerous goods escaping from the storage container first enters, and the collection area, which is used to collect the liquid dangerous goods that have escaped, can be connected to one another in a fluid-conducting manner.
- this fluid-conducting connection can be provided at least partially by a fluid line system.
- a fluid line system can be understood here in particular as an arrangement that can direct the liquid dangerous goods and/or an additional fluid, such as extinguishing fluid that has escaped from corresponding extinguishing fluid outlets, in a targeted manner in the direction of the collecting basin.
- the fluid line system can in particular be provided at least partially by corresponding fluid-conducting pipes and/or other fluid-conducting cavities. Using a fluid line system can be advantageous in particular when the storage containers are arranged in higher levels of the storage arrangement.
- the at least one deflection surface is set up in such a way that the extinguishing fluid that has escaped from the storage containers can be conducted in the direction of the fluid line system.
- the at least one deflection surface can in particular have a gradient in the direction of the fluid line system. This means that at least part of the deflection surface can have a slope which is set up to direct a fluid located on it in the direction of the fluid line system. This allows the liquid dangerous goods to be discharged more efficiently into the catch basin.
- the front bulkhead may further include at least one side guard configured to extend along at least one side surface of the storage bin.
- the front protective wall can be equipped with at least one side protection, which can be set up to cover at least part of a side surface of the storage container on which the front protective wall is arranged.
- the front protective wall can each comprise a first side protection and a second side protection, ie a respective side protection for each side of the storage container.
- the at least one - first and/or second - side protection can extend more or less orthogonally to a surface formed by the main surface of the front protective wall, and can thus be more or less parallel to the side surface of the storage container and thus also more or less run parallel to the first or second lateral protective wall when the storage container is arranged together with the front protective wall in the storage arrangement.
- the at least one side protection can completely or partially cover the side surface of the storage container.
- the at least one side guard may cover at least an area of 1/3 to 2/3 of the side area, preferably an area of 1/3 to 1/2 of the side area of the storage container.
- the advantage of this embodiment lies in an improvement in the protection provided by the front protective wall during transport and/or storage of the storage container in the event liquid dangerous goods escape from the storage container, since the at least one side protection protects against lateral leakage.
- one or more of the rear bulkhead, the first side bulkhead, the second side bulkhead, the front bulkhead, and the fluid permeable platform may be formed of a non-combustible material. It is preferred that one or more components of the enclosure, i.e. the rear protective wall, the front protective wall, the side protective walls and/or the fluid-permeable platform can be made of a non-combustible material.
- a non-combustible material can be understood to mean, in particular, a material that is not flammable or only flammable with great difficulty.
- this non-combustible material comprises a metal.
- the front protective wall, the rear protective wall and the side protective walls can be made in particular from a flat, rectangular or square component such as a (metal) sheet and the fluid-permeable platform can be made as a grating, in particular a metal grating.
- the material or materials chosen for the components may be resistant to the liquid hazardous material. Resistant to the liquid dangerous goods is to be understood here in particular as meaning that the materials are not attacked at all or only with great difficulty by the liquid dangerous goods.
- the materials for the device can therefore also be selected on the basis of the liquid dangerous goods to be stored.
- the apparatus may further include at least one first flame arrestor, the at least one first flame arrestor being disposed between the fluid permeable platform and the containment area.
- the device may further include at least one second flame arrestor, wherein the at least one second flame arrestor may be positioned between the fluid permeable platform and the at least one deflection surface.
- at least one of the first flame arrestor or the second flame arrestor can be designed as a siphon and/or as a grid.
- the device may also include a first or a second flame arrester.
- a flame arrester is to be understood here in particular as an arrangement which prevents flame transmission from one side of the flame arrester to the other. Through the use of flame arrestors can a fire event can thus be confined to a relatively small area within the device.
- the containment area may include at least a first flame arrestor.
- This at least one first flame arrester can serve to prevent a fire occurring within the catchment area from flashing over to the areas above or next to it, for example the deflection surface and/or the fluid line system.
- the at least one first flame arrestor can also prevent a fire incident, for example on the deflection surface, from reaching the catchment area.
- the at least one first flame arrester can be arranged within the catchment area in such a way that it represents a flame arrester between at least one location of a potential fire event and a location to be protected.
- the at least one first flame arrester can be arranged in particular as a flame arrester between the collecting area and the deflection surface and/or between the collecting area and the fluid line system.
- the deflection surface may include at least a second flame arrestor.
- This at least one second flame arrester can be used in particular to prevent a fire occurring within the deflection surface from flashing over to the areas above or next to it, for example the fluid line system and/or the storage container.
- the at least one second flame arrestor can also prevent a fire occurring, for example, in the interior of the housing, ie around the storage container, from reaching the discharge area.
- the at least one second flame arrester can be arranged inside and/or on the deflection surface in such a way that it represents a flame arrester between at least one location of a potential fire incident and a location to be protected.
- the at least one second flame arrester can be arranged in particular as a flame arrester between the deflection surface and the storage container or interior space and/or between the deflection surface and the fluid line system.
- the at least one first and/or the at least one second flame arrester can be set up in particular in such a way that the liquid dangerous goods and/or the extinguishing fluid and/or other fluid located within the housing through the respective - at least a first and/or second - Flame arrester can pass through, while at the same time dissipating heat from the liquid hazardous material and / or the extinguishing fluid and/or the additional fluid can be applied to the material of the at least one first and/or at least one second flame arrester.
- the at least one first and/or the at least one second flame arrestor have a ratio between fluid-permeable areas and heat-dissipating areas that enables effective heat dissipation from the respective fluids.

- the capture area may have a first acquisition volume, V AU , where the first acquisition volume may be determined as
- V A u VL+V s
- V L can correspond to a storage volume of the storage container and V s can correspond to a predetermined safety volume.
- the at least one deflection surface can have a second absorption volume V AL , the second absorption volume being smaller than the first absorption volume (V AL ⁇ V AU ).
- the catchment area has a receiving volume, ie a capacity, which makes it possible to hold the contents of a complete storage container plus a certain amount of extinguishing fluid record. This should make it possible to prevent the containment area from overflowing and the (burning) liquid dangerous goods from spreading in the event of a fire.
- the storage volume, i.e. the capacity, of the storage container can first be determined. In the case of a commercial IBC, this storage volume can correspond to 1000 liters, for example.
- This safety volume can preferably correspond to a volume of extinguishing fluid that can be applied to the device from corresponding extinguishing fluid outlets within a specific period of time in the event of a fire.
- this period of time can be determined as the period of time that is required to initiate further firefighting measures, for example by calling the fire brigade.
- the necessary safety volume can be determined. For example, assuming a period of 20 minutes until the arrival of the fire brigade, with 20 liters of extinguishing fluid per minute being let out of the extinguishing fluid outlets onto the device, the safety volume should be 400 liters.
- the storage volume of the storage area can then be determined, which corresponds to 1400 liters in the above example.
- the dimensions of the recording area can then be selected in such a way that the necessary recording volume is achieved. This can make it possible to collect the liquid hazardous material together with any extinguishing fluid that may be applied to it completely in the receiving area, at least for a certain period of time, and thus to prevent the liquid hazardous material and/or the fire event from overflowing and spreading across the storage area.
- one or more of the first lateral protective wall and the second lateral protective wall can be double-walled with an intermediate cavity, the cavity being configured to form at least part of the fluid line system, the cavity being further configured to contain leaked material from the storage containers To conduct extinguishing fluid in the direction of the collection area and / or at least one deflection surface.
- the first lateral protective wall and the second lateral protective wall can be double-walled, ie can each comprise a first wall and a second wall.
- a cavity can thus be formed between the first wall and the second wall of the first lateral protective wall.
- a cavity can also be formed between the first wall and the second wall of the second lateral protective wall.
- the distance between the first wall and the second wall of the first lateral protective wall and the distance between the first wall and the second wall of the second lateral protective wall can be selected such that the surface cross section of the cavities corresponds to the surface cross section of one used in other embodiments for the fluid line system corresponds to the pipe.
- the double-walled first lateral protective wall and the double-walled second lateral protective wall can each have an inlet opening that can be set up to introduce a fluid, in particular liquid dangerous goods, into the respective cavities and each have an outlet opening that is set up can be to output the fluid located in the cavities in the direction of the collection area and/or in the direction of another cavity of another device.
- the first lateral protective wall and the second lateral protective wall can be arranged in particular on the sides of the deflection surface, which can also have corresponding fluid outlet openings, which can be arranged to cooperate with the inlet openings into the cavities of the lateral protective walls in order to discharge the liquid Guide dangerous goods in the direction of the collection area.
- This arrangement can thus allow the liquid dangerous goods to be routed over several levels of the storage arrangement through a fluid guidance system formed by the cavities in the lateral protective walls in the direction of a collection area, without additional pipes being necessary for this purpose.
- the fluid line system formed in this way can also have one or more connecting elements which can be set up to connect the cavities of the lateral protective walls to the respective deflection surfaces in a fluid-tight manner.
- the connecting elements can preferably be designed as flexible plug-in connections which can only be arranged in the cavities and/or in the deflection surface without being firmly connected to it. As a result, the flexibility of the bearing arrangement can be retained even after it has been connected by means of the connecting elements, reducing the likelihood of damage when using heavy loads.
- the rear protective wall can optionally also be double-walled with an intermediate cavity.
- the rear protective wall can be designed analogously to the first lateral protective wall and/or the second lateral protective wall, i.e. it can have a cavity which can be set up to form at least part of the fluid line system and directs extinguishing fluid that has escaped from the storage containers in the direction of the collection area and / or to direct the at least one deflection surface.
- the above embodiments have the advantage that no additional and/or no complete additional fluid line system has to be provided in them because the first and/or the second lateral protective wall—and optionally also the rear protective wall—enable the fluid line.
- a further advantage of this double-walled design of the first and/or the second lateral protective wall and/or the rear protective wall is that this design improves the thermal insulation. If heat develops, it can be better insulated thanks to the double-walled design. In this way it can be achieved that, for example, the elements of the storage arrangement, in particular the shelf arrangement, in which the storage containers can be arranged, can be better protected against heat.

- FIG. 1 shows, schematically and by way of example, two devices 1, 1′ for the safe storage of dangerous liquid goods in a first embodiment.
- FIG. 1 shows a first device 1 which is not arranged in a storage arrangement 100 for receiving the devices 1 , V and a second device T which is already arranged in the storage arrangement 100 .
- the device 1 serves for the safe storage of a container 80.
- the device 1 comprises a rear protective wall 20 which is adapted to protect a rear side of the storage container 80 when the storage container 80 is arranged in the storage arrangement 100, as in connection with the device V shown.
- the device 1 comprises a first lateral protection wall 30 and a second lateral protection wall 40, which are each set up to protect two side walls of the storage container 80 when this is arranged in the storage arrangement 100, as shown for the device 1 by way of example.
- the rear bulkhead 20, the first side bulkhead 30 and the second side bulkhead 40 are made of a non-combustible material.
- the rear protective wall 20, the first lateral protective wall 30 and the second lateral protective wall 40 are designed as sheet metal parts. Sheet metal has the advantage that on the one hand it is not combustible, but on the other hand it is easy to process.
- the device 1 also includes a fluid-permeable platform 50 which is set up as a floor space for the storage container 80 .
- the fluid-permeable platform 50 thus serves to place the storage container 80 on it when the storage container 80 is arranged in the storage arrangement 100 .
- the fluid-permeable platform 50 is designed in particular as a grating.
- the design as a grating means that the fluid-permeable platform 50 can carry the load of a filled storage container 80 and at the same time makes it possible, if liquid dangerous goods escape from the storage container 80, in the direction of a discharge surface 60, as described in more detail below .
- the storage container 80 can be arranged directly on the fluid-permeable platform, or via an additional transport and/or arrangement platform, which in such a case should also be fluid-permeable.
- the storage container 80 is arranged on an additional transport and/or arrangement platform, which is designed in the form of a pallet 81.
- the device 1 further comprises a front protective wall 10 which is set up to protect a front side of the storage container 80 .
- the front protective wall 10 is also preferably made of a non-combustible material.
- the front protective wall 10 is here arranged on the storage container 80, in particular fastened, and can be lifted and transported together with the storage container 80.
- the protective wall 10 already protects the front side of the storage container 80 before the storage container 80 is arranged in the storage arrangement 100 .
- This allows the storage container 80 to be transported safely, since liquid extinguishing fluid is prevented from escaping in the direction of the means of transport used.
- a cumbersome and dangerous assembly of the protective wall 10 after arranging the storage container 80 in the storage arrangement 100 is prevented.
- the already installed front protective wall 10 protects the storage container 80 during transport to a certain extent against possible damage by the means of transport (not shown in FIG. 1) of a transport device (also not shown in FIG. 1), such as the tips of a forklift truck forklift.
- a transport device also not shown in FIG. 1
- the front bulkhead 10 further includes a first side guard 11 and a second side guard 12 extending approximately orthogonally to the front bulkhead 10 .
- the first side protection 11 and the second side protection 12 are used here to catch any hazardous liquid material escaping from a side area of storage container 80 and, in particular, to prevent the escaping hazardous liquid material from jetting in the direction of the front and/or to the sides of storage container 80 could ensure that the liquid hazardous material splashes and/or escapes to the front.
- the storage container 80 is protected even better against leakage of the liquid dangerous goods.
- the front bulkhead 10 is configured in the form of a sheet metal which initially runs parallel to the front of the storage container 80 and further comprises a first side protection 11 and a second side protection 12 orthogonal to the front side protection 10 and therewith extend parallel to the side walls of the storage container 80.
- the sheet metal, which serves as the front protective wall 10 is thus guided around the storage container 80 laterally to the rear.
- the front protective wall 10 and the first side protection 11 and/or the second side protection 12 as three separate components, in particular three separate metal sheets, i.e. the first side protection 11 and the second side protection 12 as individual metal sheets on one To mount sheet metal that forms the front bulkhead 10.
- first side protection 11 and the second side protection are set up in the specific embodiment of FIG. 1 in such a way that they only partially cover the side walls.
- This design is based on the knowledge that the potentially flammable liquid hazardous material escaping from the storage container 80 is more far-reaching in the lower area of the storage container 80 than in the upper area due to the higher static pressure. It is therefore necessary in this lower area to remove the first side protection 11 and to guide the second side guard 12 over a greater extent of the storage container 80. The further up the area along the storage bin
- first side guard 11 and the second side guard 12 may be configured in a triangular shape.
- the front protective wall 10 also has a transport receiving means 13, which in the first embodiment according to FIG. 1 is designed as a stable metal sheet.
- the transport receiving means 13 here extends from the plane formed by the front protective wall 10 along a direction opposite to the direction along which the first side protection 11 and the second side protection 12 extend. In the arranged state, the transport receiving means 13 is therefore outside an interior area of the housing and extends away from it.
- the transport receiving means 13 is here equipped with a certain slope, as explained in more detail below.
- This incline means that a transport device, such as a fork lift truck, with a corresponding means of transport, such as a transport fork, can be guided over this surface below the storage container 80, for example into the receptacles of the pallet 81, and thus the storage container 80 for the purpose of Raising and / or moving can go under.
- the storage container 80 is placed on the pallet
- the front protective wall 10, the rear protective wall 20, the first lateral protective wall 30 and the second lateral protective wall 40 form a housing for the storage container 80, as shown in FIG. 1 in connection with the device 1'.
- This enclosure makes it possible in case of damage to the storage container 80 from the Storage container 80 to catch escaping liquid dangerous goods and in particular to prevent this from getting out of the storage arrangement 100 in an uncontrolled manner. This catching can take place both when the liquid hazardous material has just escaped or also when a fire has occurred, ie the liquid hazardous material has already ignited. The liquid dangerous goods can then be drained from the housing through the fluid-permeable platform 50 .
- the device 1 also includes a deflection surface 60 which is designed as a deflection trough 60 in the specific embodiment of FIG. 1 .
- the deflection surface 60 is arranged below the fluid-permeable platform 50 in order to be connected to it in a fluid-conducting manner.
- the liquid hazardous material that has escaped from the storage container 80 into the housing is thus conducted via the fluid-permeable platform 50 onto the discharge surface 60 .
- the deflection surface 60 is set up to catch and collect the liquid hazardous material and thereby to buffer it to a certain extent, and then to feed it to a fluid line system, as will be explained in more detail in connection with the following figures.
- the hazardous material that has escaped is then conveyed to a collection area 70 via the fluid line system.
- the collecting area 70 is designed as a collecting pan, with one collecting pan 70 being provided for each bearing arrangement 100 .
- several or fewer collection areas 70 per storage arrangement 100 for example one collection area 70 per device 1, 1', or one collection area 70 per level of the storage arrangement can be provided.
- the catchment area 70 includes a first flame arrester 71.
- This first flame arrester 71 ensures that, should the liquid dangerous goods ignite on the way to the catchment area, the resulting flames do not penetrate in the direction of the catchment area 70 which could spread the fire.
- the collection area 70 according to the embodiment of FIG. 1 has a first recording volume V AU , which is determined as
- V A u VL + V s , where V L corresponds to a storage volume of the storage container 80 and V s corresponds to a predetermined safety volume.
- This safety volume corresponds, in particular, to a volume of an extinguishing fluid that arises at a specific escape rate, ie a specific escape volume per unit of time.
- the volume V AU is selected to be large enough to accommodate, in addition to the contents of the storage container 80, the amount of extinguishing fluid escaping from the extinguishing fluid outlets during firefighting, which escapes until further firefighting measures, for example by the fire brigade, are initiated.
- Extinguishing fluid is discharged from the extinguishing fluid outlets onto a specific collection area 70 .
- the collection area 70 should be able to hold a further 400 liters of extinguishing fluid, ie a total of 1400 liters, in addition to the filling volume of the storage container 80, for example 1000 liters.
- Figures 2A and 2B show examples and schematic devices 1, V for safe storage of a storage container 80 in a first perspective view and a second perspective view. The first side protection of the device V is not shown in the representation of FIGS. 2A and 2B for better illustration. As shown in FIGS.

- FIG. 2A the back of the storage system, formed from storage arrangement 100 and devices 1, T, is shown schematically.
- the storage system has a fluid line system 90 on its rear side, which fluidly connects the deflection surface 60 to the collecting area 70 .
- the deflection surface 60 comprises a sloping surface 61 which has a gradient in the direction of the fluid line system 90 .
- hazardous liquid material now reaches the deflection surface 60 , it is guided through the inclined surface 61 in the direction of the fluid line system 90 .
- the fluid line system 90 receives the liquid hazardous material and then directs it into the collection area 70, where the liquid dangerous goods are collected. If the liquid hazardous material is ignited here, the liquid hazardous material in the collection area 70 can also be extinguished by applying appropriate extinguishing fluid from extinguishing fluid outlets.
- the collecting area 70 has, as described above, a capacity that is sufficient to collect the entire contents of the storage container 80 and the extinguishing fluid, which emerges from the extinguishing fluid outlets within a certain period of time.
- the deflection surface 60 should preferably serve as a buffer in the event that a large quantity of hazardous liquid material suddenly escapes from the storage container 80 .
- the holding volume of the deflection surface 60 is selected to be sufficiently large, so that the hazardous liquid material that has escaped can first collect on the deflection surface 60 and then be discharged piece by piece via the fluid line system 90 .
- FIG. 2B the front side of the storage system, formed from storage arrangement 100 and devices 1, 1', is shown schematically.
- This perspective view once again illustrates the arrangement of the devices 1, V within the storage arrangement 100.
- a side wall of the collecting area 70 is not shown in the perspective view of FIG. 2B.
- the first flame arrestor 71 is arranged in the upper area of the area 70 collecting area. The liquid dangerous goods routed via the fluid conduction system 90 into the catchment area 70 and any extinguishing fluid escaping from the extinguishing fluid outlets can thus collect below the first flame arrestor 71 .
- the first flame arrestor 71 can in particular be designed to be fluid-permeable, so that the extinguishing fluid can pass through the first flame arrestor 71 into the catchment area 70 .
- the first flame arrestor 71 is designed in particular as a filter mat made of a stainless steel mesh through which fluid, such as extinguishing fluid, can penetrate, but which on the other hand prevents flames from penetrating in the direction of the collecting area 70.
- FIG. 3 shows a schematic front view of a front protective wall 10 according to the first embodiment, which has already been explained in connection with FIGS. 1, 2A and 2B.
- the front bulkhead 10 includes a first side schutz 11, a second side protection 12 (not shown) and a transport receiving means 13.

- a means of transport of a transport device for example the fork of a fork lift truck, can be guided under the storage container 80 on which the front protective wall 10 is arranged and transport the storage container together with the front protective wall 10 .
- the front protective wall 10 can also be movably arranged on the storage container 80, in particular such that the front protective wall 10 is slightly raised in the vertical direction by the transport means being guided along the transport receiving means 13. It should be understood here that, in the event that the device 1 , T is already arranged in the storage arrangement 100 , there may also be other options for specifying the front protective wall 10 without the transport receiving means 13 .
- the means of transport of the transport device could be used to approach the front protective wall 10 from below and/or in a combined vertical and horizontal movement and thus raise the front protective wall 10 .
- the front bulkhead 10 of Figure 3 further comprises two receiving elements 14 in the form of two pins. These receiving elements 14 serve, upon placement of the storage container 80 on which the front bulkhead 10 is to be placed, to cooperate with the fluid-permeable platform to hold the front bulkhead 10 in position to prevent, in the event of a sudden occurring Escape of liquid dangerous goods from the storage container 80, the front protective wall 10 would be pushed away by the liquid pressure. This would cause the front bulkhead to lose its effectiveness.
- the receiving elements 14 are configured as pins that are configured to interlock with the grid that forms the fluid-permeable platform 50 . This results in increased security of positioning of the storage container 80 in the storage assembly.
- FIG. 4 shows a schematic and exemplary schematic structure of a storage system comprising at least one device 2 for the safe storage of liquid dangerous goods according to a second embodiment and a storage arrangement 100.
- the device 2 according to the second embodiment of FIG. 4 has the same functionalities as the Device 1, V according to the first embodiment, wherein the same reference numbers refer to the same components.

- the dimensionally stable frame element can also be formed by a transport receiving means 13', as described below.
- the fluid-permeable platform 50 according to the second embodiment of Fig. 4 is again designed as a grating. This allows for better placement of the storage container 80 within the storage assembly 100 without requiring precise alignment of the storage container 80.
- Device 2 also includes a deflection surface 60, which is used to direct any liquid dangerous goods escaping from storage container 80 into a fluid line system 90 of device 2, with fluid line system 90 serving to convey the liquid dangerous goods into collection area 70 below devices 2 to conduct, as explained in connection with Figures 1-3.
- the diversion surface 60 has a relatively large capacity for the liquid hazardous material, which serves as a buffer in the event that a large quantity of liquid hazardous material suddenly escapes from the storage container 80 and cannot be discharged directly and completely via the fluid control system.
- the fluid-permeable platform 50 is designed as a grating, it allows any hazardous liquid material escaping from the storage container 80 to be guided promptly onto the discharge surface 60 and thus to quickly discharge the hazardous liquid material from the housing.
- the deflection surface 60 again serves as a buffer for the escaping liquid dangerous goods.
- the deflection surface 60 also includes at least one second flame barrier 62, which serves as an additional protective barrier in the event of a fire.
- the liquid hazardous material reaches the fluid line system 90 from the deflection surface 60 . It should be mentioned here that the length of the tubes used for this purpose can vary depending on the height of the bearing arrangement 100 .
- the bearing arrangement 100 has a two-level design.
- the fluid line system 90 arranged on the rear side of the storage arrangement 100 is set up in such a way that the liquid dangerous goods from the lower as well as from the upper floor are guided into the collecting area 70 via corresponding pipes.
- the second embodiment of FIG. 4 corresponds to the first embodiment of FIGS. 1 to 3, in which a fluid line system 90 with tubes was likewise described.

- the transport receiving means 13' can be used as a stable metal frame if it is designed accordingly.
- the front protective wall 10 according to the second embodiment also includes corresponding transport receiving means 13', which are designed as forklift shoes in the second embodiment.
- These forklift shoes are set up in such a way that they are only open in the direction of the front side of the storage container 80 and are closed at their other end. This prevents any liquid dangerous goods that may exit the storage container and reach the fluid-permeable platform 50 from being guided forwards by the forklift shoes and thus from being able to flow forwards out of the storage arrangement 100 .
- FIG. 4 also shows a transport device 200 which, in the specific embodiment of FIG. 4, is designed as a fork lift truck.
- the transport device 200 comprises a transport means 201 which, in the specific embodiment of FIG. 4 , is designed as a fork of the forklift truck.

- the transport receiving means 13' i.e. the forklift shoes, which are arranged on the front protective wall 10, and thus enables lifting, moving, arranging or the like of the storage container 80.
- the arrangement according to the second embodiment can mean that when the storage container 80 with the front protective wall 10 is inserted, there is no good view of the remaining components of the device 2, because the storage arrangement 100 can block the view.
- the use of a grating as a fluid-permeable platform 50 is therefore also advantageous here, since this means that the storage container 80 does not have to be positioned so precisely.
- a second deflection surface (not shown) can also be arranged below the storage container 80 and connected to the housing and/or the transport receiving means 13', so that the second deflection surface can be connected to the storage container 80 and the front protective wall 10 can be used in the bearing assembly 100.
- the second deflection surface can be provided in particular between the forklift shoes.
- the second deflection surface can be provided in particular for liquid dangerous goods possibly escaping from the storage container 80 into the rear region of the housing for the storage container 80 and thus in the direction of the fluid conduit system 90 and away from the front of the bearing assembly 100.
- it can also be used as a storage space for storage containers of a different type than storage containers 80, which are filled with combustible dangerous goods.
- the rear protective wall 20, the first lateral protective wall 30 and the second lateral protective wall 40 as well as the fluid-permeable platform 50 are suspended in the bearing arrangement 100, in particular two traverses of the bearing arrangement 100 so that storage arrangement levels such as shelf levels are no longer necessary.
- the size of the device 2 can in particular be chosen such that the device 2 can be introduced into a commercially available storage arrangement 100 .
- a commercially available storage arrangement 100 is, for example, a commercially available pallet rack with a width of 270 cm.
- Two devices 2 are now to be arranged in this commercially available pallet rack. This means that the width of the devices 2 must be selected so that two devices fit next to each other in the pallet rack.
- the height should be chosen so that two devices 2 can be arranged one above the other in the pallet rack. This makes it possible to retrofit standard pallet racks in existing hazardous materials storage without great effort.
- the device 2 again comprises a collecting area 70, which in the second embodiment according to FIG. 4 is provided as a collecting pan in the form of a steel container, which has a capacity which is preferably as in connection with until 3 is determined.

- the catchment area 70 preferably comprises two flame arrestors 71 per device 2 to which the catchment area 70 is assigned.
- these two flame arresters are each arranged centrally below the housing of the device 2 , in particular in such a way that liquid dangerous goods escaping from the fluid line system 90 first get onto the first flame arrestors 71 before they can get into the catchment area 70 .
- FIG. 5 shows, schematically and by way of example, a structure of a device 3 for the safe storage of dangerous liquid goods according to a third embodiment of the invention.
- the device 3 comprises a rear protective wall 20, a first lateral protective wall 30 and a second lateral protective wall 40 as well as a fluid-permeable platform 50, which together with a front protective wall 10 form a housing for a storage container 80.
- the rear protective wall 20, the first lateral protective wall 30 and the second lateral protective wall 40 can be made of metal.
- the fluid-permeable platform 50 is formed by a grating.

- the device 3 also comprises a deflection surface 60 which is arranged below the fluid-permeable platform 50 .
- the deflection surface 60 has a relatively large storage volume, which serves as a buffer in the event that a large quantity of hazardous liquid material suddenly escapes from the storage container 80 and cannot be discharged directly and completely via the fluid control system.
- the device 3 also comprises connecting elements 31, 41 and an insert plate 63, which is arranged on the deflection surface 60 and serves to direct any liquid escaping from the storage containers 80 through the flame arrestors 62 of the deflection surface 60 into the To conduct fluid line system of the device 3.
- a suspension arrangement is also arranged on the device 3 according to the third embodiment, which allows the device 3 to be partially assembled—in particular completely assembled except for the front protective wall 10 - to hang in the bearing assembly 100.
- the rear protective wall 20, the first lateral protective wall 30, the second lateral protective wall 40, the fluid-permeable platform 50, the deflection surface 60 with the insert plate 63 and the connecting elements 31, 41 are mounted on the suspension arrangement and suspended as a whole in the bearing arrangement 100.
- the hanging arrangement is designed in such a way that it is suitable for hanging in a commercially available storage arrangement 100, such as a pallet rack. That is, the dimensions of the hanging arrangement are selected such that they can interact with the struts of a commercially available bearing arrangement 100 in order to hold the device 3.
- the device 3 according to the third embodiment of FIG. 5 differs from the devices according to the first and the second embodiment according to FIGS. 1 to 4, among other things, in the design of the fluid line system.

That is, the first side protection wall 30 and the second side protection wall 40 are designed such that a cavity 32 is provided between a first wall and a second wall of the first side protection wall 30 and between a first wall and a second wall of the second side protection wall 40 a cavity 42 (not shown in Fig. 5) is provided.
- the distance between the first wall and the second wall of the first lateral protective wall 30 and the distance between the first wall and the second wall of the second lateral protective wall are selected such that the surface cross section of the Cavities 32, 42 corresponds to the surface cross section of a tube used in other embodiments for the fluid line system.
- the cross-sectional area of the cavities 32, 42 can be chosen in particular to correspond to that of a tube with a diameter of between 200 and 300 mm, more specifically between 220 and 280 mm, even more specifically of about 270 mm.
- the double-walled first lateral protective wall 30 and the double-walled second lateral protective wall 40 each have an inlet opening which is set up to introduce a fluid into the cavities 32, 42 and an outlet opening which is set up to let the fluid into the cavities 32, 42 located fluid in direction of the collecting area 70 and/or in the direction of a further cavity 32, 42 of a further device 3.

- the inlet openings and the outlet openings of the cavities 32, 42 in the first lateral protective wall 30 and the second lateral protective wall 40 are designed in such a way that they always lead a fluid, in particular liquid dangerous goods, to the respective fluid outlet openings of the deflection surfaces 60, in order to do so to prevent the liquid hazardous material guided through the cavities 32, 42 from collecting on a deflection surface 60 of a device 3 located underneath, instead of being guided further in the direction of the collection area 70.
- fluid can be guided over several levels of the bearing assembly 100 from top to bottom through a fluid guidance system formed by the first lateral protective wall 30 and the second lateral protective wall 40 in the direction of a collection area below the bearing assembly 100 . Additional pipes do not have to be provided.
- the connecting elements 31, 41 are provided. These connecting elements 31, 41 are set up with the deflection surface 60 of a first device 3 and a first lateral protective wall 30 and a second lateral protective wall 40 of a second device 3, which is in a storage arrangement 100 below the first device 3 is arranged to cooperate in order to create a fluid-tight connection between the discharge surface of the first device 3 and the cavities 32, 42 of the first lateral protective wall 30 and the second lateral protective wall 40 and thus to close the fluid-conducting system in a fluid-tight manner.
- the connecting elements 31, 41 can preferably be designed as plug-in connections that can be plugged onto the first lateral protective wall 30 and the second lateral protective wall 40 as well as an edge of the deflection surface 60, as shown again in detail in connection with FIG .

- the dimensions of the catchment area 70 are therefore adapted to the length and the width of the bearing arrangement 100 . Furthermore, the capacity of the catchment area 70 is selected such that the catchment area can completely take up the contents of at least one storage container 80 and additionally correspondingly applied extinguishing fluid.
- the collection Rich 70 of several bearing assemblies 100 ie the catchment areas 70, which are arranged side by side, are connected to one another in a fluid-carrying manner, so that fluid can optionally flow from one catchment area 70 into the next.
- the connection can be made in particular via corresponding connection elements (not shown).
- the connection elements can also be used to safely drain away fluid located in the collecting area 70 .
- the collecting trough which serves as a collecting area 70, is equipped with reinforcing elements which have the same shape and position as the crossbeams of the bearing assembly 100.
- This type of reinforcement by appropriate reinforcing elements allows the To arrange device 3 in the lowest level of the storage arrangement directly on the collection area 70 and to provide no additional brackets in the storage arrangement 100 for this purpose. This relieves the storage arrangement 100 since it does not have to bear the load of the storage containers 80 arranged at the lowest level.
- the catchment area 70 also has one or more first flame barriers 71 (not shown), which serve to separate the storage container 80 or deflection surface 60 and the liquid hazardous material in the catchment area 70 in the event of a fire.
- the housing of the device 3 is formed by arranging the storage container 80 with the front protective wall 10 arranged thereon in the storage arrangement 100.
- the front protective wall 10 comprises a first side protection 11 and a second side protection 12, as for example in the figures 6A and 6B is shown schematically.
- the front protective wall 10 has corresponding transport receiving means 13" which are set up together with a transport means 201 of a transport device 200 to act to locate the storage container 80 together with the front bulkhead 10 in the storage assembly 100.
- the storage container 80 is arranged on the fluid-permeable platform 50, as shown in FIG.
- the first side protection 11 and the second side protection 12 together with the front protective wall 10 prevent liquid dangerous goods from escaping through the front of the storage container 80 . Rather, in such a case, the liquid dangerous goods are transported in the direction of the reverse side derived.
- the storage container 80 is arranged on a fluid-permeable platform 80, the liquid hazardous material also reaches the deflection surface 60 and then into the collecting basin 70, even if it exits via the front.
- FIGS. 6A and 6B show, schematically and by way of example, a rear view and a front view of a front protective wall according to the third embodiment in detail.
- the first side guard 11 and the second side guard 12 extend in the orthogonal direction relative to the plane formed by the front bulkhead 10 and thus extend parallel to the side surfaces of a storage container 80, at which the front protective wall 10 is arranged.
- the difference from the first and the second embodiment lies in the design of the transport receiving means 13 ′′ and in the way in which the front protective wall 10 can be arranged on the storage container 80 .
- the front bulkhead 10 is adapted to be placed on the storage box 80 without lifting the storage box 80 therefor. This means that the front bulkhead 10 can be placed on the storage bin 80 even manually.
- the transport receiving means 13 ′′ are rectangular in shape in such a way that they can interact with a storage device, such as a pallet, arranged below the storage container 80 .
- a storage device such as a pallet
- the size of the rectangular area of the transport receiving means 13′′ corresponds at least to the rectangular area that is also provided for a forklift shoe.
- the front protective wall 10 can simply be pushed onto the storage container 80 and then fastened. Due to the design of the transport receiving means 13" as rectangles with the cross-section at least of forklift shoes, it is possible to continue to simply drive under the storage containers 80 with a transport device such as a forklift truck and thus pick them up for transport, despite the front protective wall being arranged.
- discharge means directed in the direction of the storage container 80 are arranged on the edges of the transport receiving means 13" and have an angular U-shape. profile and so with the rectangular shape of the transport receiving means 13".
- a further advantage of this configuration is that the front protective walls 10 can be stored in a space-saving manner before they are arranged on the storage containers 80 by being stacked on top of one another and in this way plugged into one another, so to speak.
- the dimensions of the front protective walls 10 according to the third embodiment can in particular be selected in such a way that a stack of 10 front protective walls 10 in storage takes up approximately the space of a storage container.
- the front bulkhead 10 may further include one or more handles (not shown in Figures 6A and 6B) for an assembler to grasp.
- the front protective wall 10 may further include one or more brackets or bolts (also not shown in FIGS. 6A and 6B) can be arranged with which the front protective wall can be attached to the storage container 80.
- FIG. 7 shows a connecting element 41 according to the third embodiment, schematically and by way of example.
- the connecting element 41 is designed to connect the discharge surface 60 and the cavity 42 of a first device 3 to the cavity 42' of a second lateral protective wall 40' of a second device 3', which is arranged in a storage arrangement 100 below the first device 3, in a fluid-tight manner connect to.
- the connecting element 41 is designed as a plug-in connection element, which is arranged in the second lateral protective wall 40', but is not fastened to it.
- the first device 3 and the second device 3' are now initially hung one below the other by means of their respective suspension frames in the storage arrangement 100.
- This hanging causes an outlet of the deflection surface 60 and the cavity 42 of the first device 3 to be arranged over an inlet opening of the cavity 42' of the second lateral protection wall 40' of the second device 3'.
- the connecting element 41 is located in the second lateral protective wall 40' when it is hooked in and is therefore hooked in together with it. After being hooked in, the connecting element 41 is pushed upwards in the direction of the deflection surface 60 and is connected to the deflection surface 60 . This sets up a closed fluid line system between the cavity 42 of the first device 3 and the cavity 42' of the second device 3'.
- the cavity 42 of the first device 3 is designed in such a way that at the point at which the outlet of the deflection surface 60 and the outlet of the Cavity 42 are connected to the inlet opening of the cavity 42, has a sloping protective wall 43, which is inclined so that it narrows the outlet of the cavity 42 along the direction of flow of the fluid passed through the cavity 42 towards the inlet opening of the cavity 42. This constriction prevents the fluid from getting from the cavity 42 of the second device 3 ′ into the cavity 42 and/or onto the discharge surface 60 of the first device 3 .
- the slope formed by the sloping protective wall 43 is preferably dimensioned in such a way that it fits the requirements of the respective devices 3 .
- the length over which the slope extends along the direction of flow of the fluid conducted through cavity 42 and the distance between the slope and the opposite (inner) wall of the second lateral protective wall 40 can be selected such that the flow from cavity 42 towards cavity 42' can reliably occur, but backflow is unlikely.
- the sloping protective wall 43 can be designed in particular in such a way that it increases the width between the first and second (inner) wall of the second lateral protective wall by 20% to 60%, more specifically by 30% to 50%, even more specifically by 40%. tapered.
- the cavity can have a width, i.e. a distance from the first wall to the second wall of the second lateral protective wall 40, of 50 mm, for example, with the sloping protective wall 43 running in such a way that it is 50 mm from the opposite wall at its starting point inner wall of the cavity 42 and is 30 mm from the opposite inner wall of the cavity 42 at its end point.
- the length of the sloping protective wall 43 between the start and end point can be chosen accordingly.
- the sloping protective wall 43 can in particular have a length of 1 mm to 30 mm, more specifically 5 mm to 30 mm, more specifically 10 mm to 30 mm, in particular 10 mm, 15 mm, 20 mm, 25 mm or have a value in between.
- Other dimensions are also conceivable as long as they meet the above properties of allowing flow and preventing backflow.
