Description

pallet container

The invention relates to a pallet container for storage and transportation of particular flammable or easily inflammable liquid products with a

thin-walled rigid inner container made of thermoplastic material, which has a screw cap closable upper filler neck and possibly. A frontally arranged in the bottom area sampling connection if necessary. With attached removal fitting, with a plastic inner container as a support jacket tightly enclosing tubular frame made of welded tubes together and with a bottom pallet, on which the plastic container rests and with which the pipe grid frame is firmly connected, wherein the plastic inner container is enclosed within the pipe grid frame of a fire-resistant insulating mat. The present invention equally relates to pallet containers without bottom-side removal fittings, in which e.g. the sampling nozzle is welded shut or no sampling nozzle is present or provided.

State of the art:

A generic pallet container is known from DE 197 47 690 A1 (Sotra), which are characterized by a fire-retardant construction and a sufficient

Should have fire resistance. For this purpose, a thin-walled thermal insulation is in this pallet container between plastic inner container and lattice cage

arranged, which consists of cardboard and aluminum foil. This plate-shaped insulation should also be used at least in steel pallets between inner container subfloor and pallet topsoil. The side facing the plastic container side of the insulating layer is made of cardboard and the grid frame associated with the insulating layer should be made of aluminum, the aluminum layer is to serve as a heat shield and heat dissipation, while the cardboard layer should cause an insulating effect by difficult heat transfer. The insulating layers of cardboard and aluminum can additionally between weather-resistant outer layers of plastic, z. As polyethylene be arranged. A disadvantage of this known embodiment is that the bottom-side removal fitting

CONFIRMATION COPY and the entire inner container topsoil with filler neck and screw cap remains freely and openly accessible and these components are thus exposed to the flames of an adjacent fire completely unprotected. As a result, such a pallet container with insufficient flame protection only very briefly withstand the effects of an externally acting fire.

In DE 101 61 693 A1 (Sch-Pro) a similar pallet container with fire protection equipment is disclosed in which between inner container and grid frame on

Metal sheets existing fire protection jacket is arranged. Furthermore, between

Fire protection casing and inner container provided an additional fire and heat insulation, which also covers the top and bottom of the plastic inner container. The plastic inner container is also surrounded by a grid-like sheath of thin metal wire to dissipate electrical charges. The fire and

Thermal insulation consists of a 2 mm thin fiberglass nonwoven layer (glass wool fire protection material). In the metal sheets of the fire protection jacket and the insulating layer underneath, d. H. in the cover for the inner container topsoil and the front pallet container wall, corresponding recesses are for one

unimpeded access to the upper filler neck formed with removable screw cap and the bottom outlet valve. The recess for the lower

Removal fitting is closed by a fold-down sheet metal lid to protect them.

This well-known pallet container to the fire protection guidelines according to the US standard NFPA-30 for the storage of flammable and highly flammable liquids by the

Underwriters Laboratories (UL) shall comply with and shall protect the inner bladder against damage or leakage of the liquid contents for at least 20 minutes in the case of fire (assisted by a sprinkler system).

In this embodiment, however, is disadvantageous that the screw cap on the upper filler neck is completely free and unprotected. During a fire test, it was found that the sheet metal parts of the fire protection jacket used warp and deform in such a way with external heat effect that gaps at the abutting edges and between the

Forming sheet metal flap and the front metal sheet through which heat and flames can penetrate. As a result of the flames reaching the lower removal area, the plastic valve began to burn and, as a result, already occurred Leaks after 10 minutes. This known construction of a fireproof pallet container also requires a complex and costly production and assembly with insertion of the additional components of the sheet metal casing including the upper cover sheet metal plate. Also, the blow-molded plastic inner container is electrically isolated from the grid frame and the bottom tray by the glass fiber insulation, so that a lattice-like wrapping of thin metal wire is required as an electrical connection for discharging electric charges.

It is an object of the present invention to further develop a generic pallet container with flame retardant equipment such that the existing disadvantages of the prior art are overcome and an improved and cheaper version is made available to the special customers of this particular product.

Solution: This object is achieved with the special features of patent claim 1. The features in the subclaims show further advantageous

Design options of erfindungsgenmäßen pallet container on.

Due to the fact that the fire protection insulation mat on all sides, d. H. from all six sides, around the cube-shaped plastic container is also arranged in front of the upper screw lid region and bottom-side product-removal region, and the

Adjacent side edges of the individual wall sections of the fire protection insulation mat in the four vertical rectangular corner areas or / and in the horizontal upper and lower rectangular corner areas along the side edges of the plastic inner container overlap a piece, is in a simple but safe way

ensures that the heat - sensitive inner container made of thermoplastic material is protected at all points from direct exposure to fire, wherein in the

Fire protection insulation mat in the area around the screw cap for the upper filler neck and in the area around the patch removal fitting each one openable and resealable overlapping cover flap is formed, whereby the screw cap and the removal fitting are completely covered and accessible at all times.

In an advantageous embodiment of the invention it is provided that the four separate

Blank parts of the fire-resistant insulating mat for the four side walls of the plastic inner container with their respective overlapping overlapping strips consist of two identically sized sections and two sections of different sizes, with their attached overlapping sections are designed so large that - waiving a separate

Insulating mat section for the upper floor of the plastic inner container - a complete overlapping covering of the upper floor takes place together with the filling opening. In this case, the two equal sized blank parts of the fire protection insulation mat for the two longer side walls of the plastic inner container each have a hanging overlap strip with a width of about 100 mm to 450 mm, preferably about 300 mm, in a simple way as a wide Overlapping strip to cover the

Upper bottom of the plastic inner container are formed from above laterally on the topsouch hinged.

A further embodiment of the invention provides that the two different sized blank parts of the fire protection insulation mat for the two shorter

Side walls of the plastic inner container with two different widths

Overlapping strips as cover flaps for the topsoil of the inner container

equipped, wherein the rear blank portion of the fire-protective insulation mat has a lap strip with a width of about 300 mm to 550 mm, preferably about 450 mm, and the front-side blank part of the fire protection insulation mat a

Overlap strip with a width of about 1100 mm to 600 mm, preferably about 850 mm.

For the protection of the plastic inner container in the lower area of the outer

Flame effect protected pallet container is the blank part for the

Bottom surface of the plastic inner container on all four side edges, each with an overlap strip, with only the two opposite narrow overlap strips on the long side edges of the inner container have an equal width of about 50 mm to 125 mm, preferably about 75 mm. The width of the respective overlapping strips and cover flaps is always measured at right angles from their connecting line (bent edge) with the respective flat blank section.

The overlapping strip of the blank parts of the fire-resistant insulating mat is of great importance in this invention. For this purpose, it is provided in a further embodiment that the blank part for the bottom surface of the plastic inner container at the shorter rear side edge of the inner container overlap strip with a width of about 100 mm to 200 mm, preferably about 150 mm, and at the shorter front Side edge of the inner container has an overlap strip with a width of about 100 mm to 300 mm, preferably about 200 mm, said overlapping strip is interrupted in the middle and provided with a recess for access to the removal fitting. In order to be able to protect the removal fitting safely against undesired effects of heat, the invention provides that on the underside of the blank portion for the bottom surface in front of the recess in the overlap strip on the shorter

front side edge of the inner container a rectangular portion of the

Fire protection insulating mat is sewn, with the recess for the removal fitting on the side edges is fully overlapping coverable.

To meet various requirements, is the fire-resistant insulation mat

expediently formed in two layers and has for this purpose an outer heat-resistant textile fabric layer and an inner layer of heat-resistant fiber fleece. The outer textile fabric layer is equipped with a metal powder-containing polyurethane coating, which is formed by filling with aluminum powder electrically conductive (dissipative).

To derive electrical charges from the surface of the plastic inner container, a direct contact with this must be made to the outside, including the closable overlapping cover flaps of the fire protection insulation mat for the upper screw cap and the lower removal fitting also inside equipped with the electrically conductive textile fabric layer are. This also makes the handling of the cover flaps more pleasant because you do not directly with the hands in contact with the inner,

Fiberglass-containing fiber fleece of the fire protection insulation mat comes.

For applications with normal requirements, it has been found for the thermal protection of the pallet container thus equipped against the effects of heat of a blazing fire, that it is sufficient if the inner nonwoven layer and the outer fabric layer of the fire protection insulation mat for a one-sided short-term (less than a minute ) Temperature load of at least about 600 ° C are designed.

Accordingly, it is provided in the same cost-effective manner that the inner nonwoven layer and the outer textile fabric layer of the fire protection insulation mat for a one-sided permanent (over five minutes) temperature load of about 550 ° C are designed. For extraordinary applications with extreme heat protection requirements, the inner fleece layer and outer fabric layer of the fire-resistant insulating mat can be designed for a one-sided short-term (under one minute) temperature exposure of about 1600 ° C and for a one-sided lasting (over five minutes)

Temperature load of 1200 ° C be designed.

In an embodiment of the invention is advantageously provided that the

Fire Protection Insulation Mat Overall With Outside Textile Fabric Layer And Inner

Nonwoven layer has a thickness between 5 mm to 8 mm, preferably 7 mm, wherein the thickness of the outer textile fabric layer is only 1 mm to 2 mm, preferably about 1, 5 mm. The overlapping strips according to the invention with double wall thickness of the individual wall sections of the fire protection insulating mat are on the one hand in the four vertical corner areas of the grid frame or the plastic inner container and on the other horizontally circumferentially at the top and bottom of the grid frame. Along the side edges on the 90 ° bends of the plastic inner container, the distance to the tube bars of the lattice frame is greater than in the planes

Side walls of plastic inner container and grid frame, so that in these

Corner areas between the plastic inner container and the outer grid frame

Advantageously, there is sufficient space for the double-layered overlapping strips of the fire-resistant insulating mat.

According to a further embodiment of the invention, the front and / or the rear side wall part of the fire protection insulation mat is designed to be extended upwards so that it can be laid above the screw cap in the manner of a cover flap or in

Direction to the opposite side wall part can be laid one above the other, whereby a far-reaching overlap of the upper insulating mat parts is achieved and the screw cap is completely and safely covered. The front and the back

Cover flap are each passed under the two transverse members of the lattice frame and are fixed by these on the top floor of the plastic inner container. Preferably, the front cover flap is made a bit longer than the rear cover flap. The rear - slightly shorter - cover flap extends almost to the upper filler neck. The front flap, the on the

Filler cap screwed screw cap covers, extends approximately to the rear Crossbeam. To close the fire-resistant insulating mat, the end or the front edge of the front - slightly longer - cover flap is pushed under the front edge of the rear cover to about the rear cross member, so that the front cover is covered by a piece of the rear cover, or the two cover flaps overlap by a good distance.

As a safe protection of the lower removal fitting is the complete Ab- or

Covering the bottom recess for access to the removal fitting in the front side wall blank part of the fire protection insulation mat provided a separate rectangular blank part, which is larger than the rectangular

Recess for the removal fitting is formed, wherein the separate blank part of the fire protection insulation mat is sewn to the bottom edge of the fire protection insulating mat below the plastic inner container so that it folds as a cover flap from bottom to top in front of the recess and behind a horizontal grid bar is designed to be clamped. This prevents certainty that in the event of fire, flames can enter the free space around the doghouse, which - as was usual with known pallet containers of this type - the projecting into the free space, made of plastic extraction valve and its handle quickly melt and burn.

By the above-indicated features of the present invention, it is possible to form a generic pallet container with flame retardant device such that it is easier and cheaper to produce, consists of fewer components and weight is lighter, the tightness of the filled plastic inner container at least for a duration of flame exposure of about 25 minutes is guaranteed.

Further advantages of the present inventive solution are in particular: The inside fiberglass-containing fiber fleece layer is usually non-conductive. In the present construction, the antistatic / conductive coated fabric of the outer layer is also applied on the inside in the region of the filler neck and the removal fitting and thus in direct contact with the plastic inner container. Thereby is a grounding of the dissipative blown part over the conductive inner layer to

Fabric outside and thus guaranteed to the mesh basket or the bottom tray.

The invention will now be described schematically with reference to the drawings

In FIG. 1, the reference numeral 10 denotes a pallet container (UL-IBC) according to the invention with a filling volume of 1000 l, with a (not shown)

thin-walled rigid inner container made of thermoplastic material for storage and the transport of particularly dangerous flammable liquids, with a plastic container as a support jacket tightly enclosing tubular lattice frame 12 and a bottom pallet 14 on which the plastic container rests and with which the support shell is firmly connected. The pipe grid frame 12 (outer container) of the

Pallet container 10 consists of welded together vertical and horizontal tubes 16, 18. To obtain a closed outer container, the

circumferential horizontal tubes 18 each connected to each other. The bottom pallet 14 can be designed as a steel pallet, as a composite pallet (tubular steel frame with plastic feet) or as a special heat-resistant wooden pallet. In this pallet container 10 is waiving an all-round metal jacket cladding - a fire protection insulating mat 20 arranged as a complete enclosure directly between the pipe frame frame 12 and the plastic inner container. The fire-resistant insulating mat 20 consists of several, preferably five, different sized sections that are in the

Corner areas of plastic inner container and tubular frame 12 each overlap a piece. This overlap or overlap of the adjacent

Blank parts of the fire protection insulating mat 20 should be at least about 20 mm to 120 mm, preferably about 75 mm. These overlapping strips 22 formed in this way extend in the vertical direction at the upper and lower edge of the tubular lattice frame 12 or of the plastic inner container in the horizontal direction and in the rectangular corner regions of the adjoining side walls of the tubular lattice frame 12

Direction.

The screw cap screwed onto the filler neck centrally located in the upper bottom of the inner container is covered by an upper large cover flap 24 and the lower removal fitting is covered by a smaller cover flap 26, so that the plastic inner container is completely enveloped and completely packed, and in the case of fire no flames and direct heat (hot air) can get to him. The sections of the fire-resistant insulating mat 20 are not sewn together, because this would be too laborious and costly. They are just in the

Tube lattice frame 12 is set and clamped in the overlap strip 22 itself until the inner container is used and all sections are clamped between the inner container and the pipe grid frame. The only exception is the small rectangle section for covering the removal fitting, which is firmly sewn to the bottom section 32. This small cover flap 26 is to its fixation in the closed State only pushed behind the first transverse grid tube rod (horizontal rod) above the sampling fitting and thereby clamped. Upon access to the lower removal fitting, the cover flap 26 can simply be pulled out by hand behind the transverse tube rod and put behind it again for closing. The long upper cover flap 24 for covering the screw cap on the upper filler neck is in the case of closure under the front edge of the

opposite, from the rear wall portion 42 on top of the plastic inner container unfolded overlap strip 44 to one above

transverse cross-beam 48 inserted and thereby fixed. To open or to expose the screw cap, this cover flap 24 is pulled out from under the overlap strip 44 and after filling the inner container and screwing the screw again under the opposite overlap strip 44th

inserted and clamped.

FIG. 2 shows, in a circular section, the structural construction of the fire-resistant insulating mat 20, which is here formed in two layers with an outer textile fabric layer 28 and an inner non-woven fabric layer 30. The outer textile fabric layer 28 is provided with a polyurethane coating. The coating is enriched with a metal powder. The metal powder is preferably made of aluminum pigments. This surface coating of polyurethane with aluminum powder is applied on the one hand for high heat radiation. This polyurethane coating shows beside

water repellent properties and antistatic properties (30-50 GO - 100V), whereby the inventive UL-IBC is suitable for EX applications and can be certified with appropriate EX approval. The textile fabric of the outer textile fabric layer 28 used is made of high quality partially textured and twisted yarns and is ideally suited for thermal and acoustic insulation with high temperature resistance. It is available in a low-cost version for medium-high claims with short-term temperature load of about 600 ° C and permanent temperature load of about 550 ° C under the name "isoTEX" freely available on the market and is commonly used as a heat protection fabric z. B. for welding curtains and fire blankets. For the highest temperature loads with a short-time load of approx. 1600 ° C and permanent temperature effect of approx. 1200 ° C, a special textile fabric is freely available on the market and available. This high temperature resistant "silTEX" protective fabric has been specially designed for long - term and durable use in the

High temperature range developed and is not flammable. It is particularly suitable as a heat protection and insulating fabric for the highest temperature stress and provides excellent protection, even against liquid metal splashes and glowing slags. In the inner nonwoven fabric layer 30, the nonwoven fabric used is composed of mechanically needled silicate glass fibers having excellent insulating properties and high

Temperature resistance. The fleece mats are very flexible and are used industrially for insulation or insulation; they are available on the market under the name "isoFLEX" for these purposes.

In Figure 3, all six individual wall sections are shown with the outer overlap strips 22 of the fire protection insulation mat. Base part is a large bottom wall portion 32 with dimensions of 1000 mm x 1170 mm with laterally revolving folded overlap strips 22 on all four side edges, the front, slightly higher overlap strip 34 has a recess 36 for accessing the

Removing fitting has. For overlapping coverage of this recess 36 and to protect the removal fitting, the small rectangular cover flap 26 is provided, which is firmly sewn below the bottom wall portion 32. Furthermore, the fire-resistant insulating mat comprises two opposing sections 38 for the longer side walls, each with large overlap strips 40 at the top. For the shorter side walls, d. H. for the rear rear wall, a section 42 is provided with a large slightly trapezoidal overlap strip 44 at the top and for the front wall a rectangular section 46 with a very large slightly trapezoidal overlap strip at the top, which is very large

Overlapping strip is referred to as upper large cover flap 24, since it is folded over the screw cap of the upper filler neck.

For a better understanding is shown in Figure 4 in a perspective view, as the individual sections of the fire protection insulation mat 20 in composite cubic shape with open upper floor, or with unfolded upper overlap strips 40, 44 and unfolded upper cover flap 24 in the corner areas with the Overlap overlap strips 22 (without enclosing tubular lattice frame of the pallet container).

FIG. 5 shows the cubic shape of the assembled sections of the fire-resistant insulating mat 20 with the top floor closed or with the top folded in, respectively

Overlap strips 40, 44 and folded upper cover flap 24 can be seen. In this case, the front of the upper cover flap 24 is covered by a piece in the order of about 50 mm to 100 mm from the wide upper overlap strip 44.

Of course, the assembly of the individual sections of the fire-resistant insulating mat 20 does not take place in free space, but gradually into the pipe grid frame 12 of the pallet container. First, the bottom wall portion 32 is placed symmetrically on the surface of the bottom pallet 14 and the small cover flap 26 for the removal fitting is pulled out between the two central vertical bars. The slightly longer overlap strips 34 of the front wall and the rear wall are raised from the inside against the pipe bars of the lattice frame, then the two narrower overlapping strips 22 of the longer side edges are also raised from the inside against the pipe bars. Of the four side walls then the front wall portion 46 of the fire-resistant insulating mat 20 is suspended in the grid frame 12, wherein the lateral overlap strips 22 are bent in the vertical corner areas from the inside against the adjacent side walls of the tubular grid frame such that each of the outermost vertical bar of the adjacent

Side wall is covered by at least 10 mm. The upper large cover flap 24 at the top of the front wall 46 initially remains free to the outside. Thereafter, the opposite section of the fire-resistant insulation mat for the shorter

Rear wall of the plastic inner container inserted into the pipe grid frame 12, wherein the lateral overlap strips 22 in the vertical corner areas

equally from the inside against the adjacent side walls of the

Tube grid frame are bent such that each of the outermost vertical rod of the adjacent side wall is covered by at least 10 mm. To complete the two opposite longer side walls are now used and pressed from the inside against the pipe grid frame and at the side edges in the vertical corner areas from the inside against the overlap strip 22 of the front wall 46 and rear wall 42. Finally, the plastic inner container is inserted and the upper wide overlap strips 40, 44 and the upper large cover flap 24 are folded onto the top bottom of the inner container.

On the upper floor of the inner container, two upstanding eyelets are laterally next to the filler neck or screwed on the screw cap, which are inserted through specially provided slots in the upper overlap strip 44 and the cover flap 24 of the fire protection insulation mat 20 so that they protrude upwards ( see Fig. 1). By this upstanding eyelets two transverse metal rods, the so-called cross members 48 are inserted through and screwed to the upper outer edge of the pipe grid frame 12. These crossbeams 48 are used for secure fixing and holding down the overlapping four sections of the fire-resistant insulating mat 20 (overlapping strips 40, 44 and large cover flap 24).

In Figure 6 and Figure 7 are again the individual blank parts from the inside with outer overlap strips for the subfloor, the front and rear walls and for the two opposite side walls with further details

shown. Thus, in the shorter upper cover flap or the overlap strip 44 at the upper edge, a region 50 is executed dotted gray; Similarly, such a dotted gray area 50 at the bottom of the floor insulating mat 32 is performed directly in front of the recess 36 in the overlap strip 34 and almost the entire

Underside of the large cover flap 24 is drawn as a dotted gray area 50. These gray dotted areas 50 symbolize that here also the inside (or underside) of the fire-resistant insulating mat is covered with the silver-colored outer textile fabric layer (28).

The small cover flap 26 shown in FIG. 8 is covered over its entire area as a dotted gray area 50 with the electrically conductive textile fabric layer. At the bottom of the attachment seam is still visible, by means of which the cover flap 26 is sewn to the bottom portion 32. These gray dotted sections are in the

Handling the generic pallet container by the operator often touched by hand, such. B. when opening and closing the upper cover flap 24 for unscrewing the screw cap when filling the pallet container and when opening and closing the lower cover flap 26 for operating the sampling valve for filling removal from the pallet container. The silver textile fabric layer In particular, without protective gloves much more pleasant to touch than the fiberglass fleece on the inside of the fire-resistant insulation mat. Furthermore, these inside areas 50 are very important for direct contact with the plastic inner container with the electrically conductive textile fabric layer for EX approval of the pallet container, because they ensure the safe discharge of electrical charges from the surface of the plastic inner container and prevent one

unwanted dangerous sparking.

In the shorter upper cover flap or the overlapping strip 44 (FIG. 6) and in the large cover flap 24, two sewn-out slots 52 are shown - drawn out to the left - through which the eyelets for the cross members are inserted in the finished assembled pallet container.

From the previous description and the figures representations it is clear that in the corner areas on the top floor of the inner container each have a fairly large area is overlapped and thus there is a double wall thickness of the fire-resistant insulating mat. For this purpose, the overlap strips 40, 44, 24 of the fire protection insulating mat on the top floor of the plastic inner container considerably wider

designed so that in particular the corner regions of the inner container are better protected from above. For one thing, this is very useful because it is in the top

Inner container even when completely filled with liquid is still a bubble and the liquid can make no heat dissipation from the surface wall of the inner container. On the other hand, because in a stacking the existing plastic corner feet can start to burn and can represent an additional source of fire or an additional source of heat.

For special protection of projecting from the lower sampling nozzle removal fitting is provided in an advantageous manner that within the indentation in the lower

Front wall of the plastic inner container (doghouse) behind the lower small cover flap 26 a cup-shaped heat protection cover made of the same material as the fire-resistant insulating mat - as protective cover 54 wrapped around the removal fitting or slipped over so that they the free space within the indentation around the patch removal fitting around behind the cover flap 26 is almost filled and is thus prevented that hot air to the also made of plastic

Removing fitting can get. For this purpose, the guard also pillow-like or be designed voluminous. In Figure 9 and Figure 10 is the separate additional

Heat protection cover 54 shown in two different perspective views. This protective hood 54 is particularly at long sampling socket or long

Removal fittings housings such. B. used in a Camlock connection.

Conclusion: Basically, a "flameproof" insulation of the outlet area is very important. This has a 15 minute fire test with a well-known UL IBC of the beginning

state of the art, in which the fire protection insulation had not remained tight because the protective sheet metal parts had ragged unevenly.

In addition to the flame-tightness is also to ensure that the approximately 900 ° C hot

Combustion air can not penetrate into the doghouse. This could be realized in a 45 minutes fire test with a pallet container according to the invention with good overlap of the insulating mat parts without leakage. The

individual pieces of tissue remain close to each other, they do not deform, so that even the handle of the sampling valve remained intact. Increasing the safety of the extraction fitting and the handle can be done in special cases by using a

separate guard be achieved.
