    [0002] Tank truck for the transport of algae from cryogenic fluids, liquefied gases, hydrocarbons at high pressure or low pressure.
    [0003]
    [0004] DESCRIPTION OF THE INVENTION
    [0005] The present invention concerns the field of tanker trucks for the transport of cryogenic fluids, liquefied gases, hydrocarbons, hydrogen at high or low temperature and at any pressure by means of their self-propelled, autonomous, entrained, robotic (drone) transport movement. The tank truck may be for the use of the supply, distribution of said hydrocarbons, gases and / or for the proper firing of the propulsion system, truck engine (tractor). This type of tank truck consists of a tank, tank, cistern formed by a compartment where an alloy is housed in the form of a mesh or spheres with anti-explosive properties. Said cistern or tank is attached, incorporated into a chassis that supports at least two pairs of wheels, and anchoring means, fastening to a body to produce its drag, displacement and transport. Said cisterns, tanks may be located partially, totally in any position and even submerged within the chassis of the truck itself and / or be located in a mixed manner with the transport of other products, merchants as in the truck trains used in Australia in which there is a tractor that drag several platforms, axes, semi-rigid, and which could also drag a cistern with hydrocarbons, liquefied gases, LPG, LNG, but at the same time can even supply independently, dual, simultaneously said hydrocarbons , gases to the propulsion system, engine of the truck itself to ace! increase autonomy, reduction in operating costs, drastic reduction of environmental impact and without the risk of explosion for any reason.
    [0006]
    [0007] The alloy in the form of mesh or spheres that is incorporated in the compartment or structure of the cistern, is conformed by the body of the alloy. This is formed by sheets of perforated material, these are provided by at least one arc of a plurality of polygonal openings, and at least one of those polygonal openings is irregular with respect to at least one contiguous polygonal aperture and having a surface area per unit volume of a container container, tank, tank and having a heat conduction capacity of at least about 0.023 Cal / cm-sec.
    [0008]
    [0009] It should be noted that, preferably, the peripheral internal length of one of the openings is different from the internal peripheral length of at least one of the adjacent openings, and, moreover, the invention, preferably has a compression field no greater than to 8%.
    [0010]
    [0011] With the invention the problem of the transport of cryogenic fluids at high pressure and low temperature is solved, without there being danger of explosion.
    [0012]
    [0013] BACKGROUND OF THE INVENTION
    [0014] State of the art
    [0015] Cisterns are currently known for the transport of cryogenic fluids, liquefied gases of the described type equipped with a cryogenic cistern formed by an interior compartment and an outer compartment separated by an insulating chamber subjected to total or partial ford in the form of algae insulation. This type of tanks contain liquefied gases at pressures higher than the atmospheric pressure and at temperatures below atmospheric temperature.
    [0016]
    [0017] The geometry of this type of cryogenic tanks is limited by its resistant and safety requirements, so! as per the rules of road transport.
    [0018]
    [0019] This leads to the need to create a tank, cistern of any geometry, but the most viable being the cylindrical shape with its ends closed by spherical or rounded caps and at the same time being able to be filled with the anti-algae alloys of this patent. This geometry provides unique safety properties, anti-explosive and also great resistance to internal pressure and an optimized transport volume for transport within the maximum dimensions allowed for the transport of goods.
    [0020]
    [0021] However, the fact of having the front part supported on a truck chassis determines an elevated position of said tank truck, which implies a high center of gravity that can be unstable and cause accidents. That is why it requires solutions that reduce the center of gravity of tanker trucks. With the introduction of drastic reduction of water hammer / movement of liquids (liquid sloshing) which allows maximum operational safety and maximum reduction of possibility of return.
    [0022]
    [0023] With this solution the capacity of the transport is not reduced, from the volume of fluids in volume transported to being less than 0.5% -1.5% the loss of the volume transported by the use of said alloys. Facilitates its construction by not requiring the incorporation of screens or anti-movement barriers of metal fluids inside, and allows a maximum structural resistance to be completely structurally firm and reduces the possibility of these structures by reducing the impact of the ram Hides.
    [0024]

    [0059]
    [0060] A thin sheet of material used in the present disclosure, as shown in Figures 3, 4 and 5, as an example, comprises a sheet of material 10 having a plurality of parallel lines P (Figure 3) of elongated rectangular openings (12), preferably grooves.
    [0061]
    [0062] Each rectangular opening (12) and each line P of rectangular openings (12), extends parallel to the central longitudinal axis of the sheet.
    [0063]
    [0064] Each rectangular opening (12) in a line P of rectangular openings (12) is spaced apart from the preceding rectangular opening (12), and the rectangular opening (12) that follows it through an intermediate network (14) of solid and Non-perforated sheet material.
    [0065]
    [0066] In summary, to proceed longitudinally along the line P of rectangular openings (12), there is a rectangular opening (12) followed by an intermediate network (14), followed by a rectangular opening (12), followed by an intermediate network (14), and so! gradually.
    [0067]
    [0068] When forming a sheet with polygonal openings, the intermediate nets (14) of the contiguous lines of the rectangular openings are outside with respect to each other, in such a way that when proceeding transversely through the sheet following a line T perpendicular to the central axis of the sheet and passing through an intermediate network (14) of a contiguous longitudinal line P of rectangular openings (12), having to take into account the following:
    [0069] to. the transverse line (7) must pass through the rectangular opening (12) of the next longitudinal line P adjacent to the longitudinal openings (12).
    [0070] b. then, it should pass through an intermediate network (14) of the next longitudinal line P contiguous to the longitudinal openings (12).
    [0071] c. then, it must pass through the rectangular opening (12) of the next contiguous longitudinal line of longitudinal openings, etc.
    [0072]
    [0073] In this way, the rectangular openings (12) which are longitudinally understood, alternate with intermediate networks 14 transversely through the sheet (10).
    [0074] passing along a transverse line T of rectangular openings (12), being different from the length of the rectangular opening (12) that precedes it and the length of the rectangular opening (12) that follows it.
    [0075]
    [0076] In other words, the length of each rectangular opening (12) extending longitudinally is preferably different from the length of the next adjacent rectangular opening (12) extending longitudinally in a transverse line T across the width of the sheet , and furthermore, with respect to each rectangular opening (12), the length of each of the four rectangular openings (12) closest to the two closest longitudinal edges P of rectangular openings (12) must preferably also be different from that of the rectangular opening (12).
    [0077]
    [0078] The lengths of the respective longitudinally extending rectangular openings (12) in a transverse line T across the width of the sheet must be random with respect to each other and, alternatively, the lengths of each respective rectangular opening (12) which extends longitudinally must increase progressively in length in a transverse line T across the width of the sheet or decrease in length.
    [0079]
    [0080] In an alternative embodiment, the lengths of each longitudinal opening (12) extending longitudinally progressively increases in length in a transverse line T across the width of the sheet and the lengths of each rectangular opening (12) extending longitudinally in the next transversal line T decreases progressively in length through the width of the sheet.
    [0081]
    [0082] The nominal length of the openings (12) ranges from about 10 mm to about 15 mm, desirably from about 12 mm to about 15 mm, and preferably from about 13 mm to about 15 mm.
    [0083]
    [0084] Thus, an opening of 10 mm is followed by a 10.033 mm, followed by a 10.06 mm, and the width of each rectangular opening, or slot, should be from about 0.02 mm to 0.06 mm, preferably from about 0.03 mm to about 0.05 mm and preferably from about 0.04 mm to about 0.05 mm.
    [0085] material used for the sheet.
    [0086]
    [0087] The intermediate network between openings, in turn, ranges from around 2.5 mm to around 4.5 mm, and thus an intermediate network of 3 mm should be followed by a 3.5 mm, followed by a of 4 mm.
    [0088]
    [0089] In this way, the irregularity is induced in the expanded perforated sheet and its configuration produces a resistance to settlement and compaction.
    [0090]
    [0091] A thin sheet of the material used in the invention, as illustrated in figures 6, 7, 8 and 9, becomes an expanded and perforated sheet (or with windows) of the material (20) of the invention , and is provided with a plurality of plurilateral or polygonal openings (22), as is, for example, that illustrated with hexagonal openings, and at least one of the polygonal openings is irregular with respect to at least one of the polygonal openings contiguous
    [0092]
    [0093] For example, the sum of the lengths of the inner edges of the faces of a polygonal aperture (22), for example lengths (22a), (22b), (22c), (22d), (22e), and (22f) of Figure 9, determines a peripheral internal length of a polygonal aperture (22) and the internal peripheral length of each polygonal aperture (22) when proceeding along a transverse line T of polygonal apertures (22), must be different from the internal peripheral length of the polygonal opening that precedes it and the internal peripheral length of the polygonal aperture (22) that follows it. (Figure 8).
    [0094]
    [0095] In other words, the peripheral internal length of each polygonal aperture (22) is different from the peripheral internal length of the next contiguous polygonal aperture (22) in a transverse line across the width of the sheet.
    [0096]
    [0097] Furthermore, with respect to each polygonal aperture (22), the internal peripheral length of each of the four polygonal apertures (22) closest to the two longitudinal edges, closest to polygonal apertures (22), should preferably also be different from the polygonal opening (22).
    [0098] transverse T across the width of the sheet, it must be random with respect to each of the others and alternatively, the internal peripheral lengths of each respective polygonal aperture (22), must progressively increase in peripheral internal length in a transverse line T across the width or decrease.
    [0099]
    [0100] In an alternative embodiment, the peripheral internal lengths of each respective polygonal aperture (22) progressively increase in length in a transverse line T across the width of the sheet and the internal peripheral lengths of each respective polygonal aperture (22) in the next transverse line T decreases progressively in length across the width of the sheet.
    [0101]
    [0102] The term "irregular", as used herein in the context of the internal peripheral length of at least one of the openings that is unequal to the internal peripheral length of at least one contiguous opening, means that the numerical value of the inequality of the internal peripheral length with respect to the other peripheral internal length is greater than the variation in peripheral internal length produced by the variation in manufacturing or the inherent variation of manufacturing.
    [0103]
    [0104] While the irregularity of at least one polygonal aperture with respect to at least one contiguous polygonal aperture has been described in terms of the peripheral internal length of at least one of the apertures which is unequal to the internal peripheral length of at least one contiguous aperture, it must be understood that the irregularity can also be produced in other ways, such as having a different number of sides of the pogon (as a pentagon or a heptagono with respect to the hexagon) or in the length of one side of a polygonal aperture that is different on the corresponding side of a contiguous polygonal aperture (ie, greater than the variation or tolerance of the manufacture as indicated above) or the angle between two contiguous sides of a polygonal aperture is different from the corresponding angle between the two corresponding sides of a contiguous polygonal opening, for example, the respective lengths of the side edges of the openings may not be all the same, (that is, at least one side may not have the same length as any of the other sides, so it provides an opening that has the configuration of an irregular phogon).
    [0105]
    [0106] In this way, when expanded, perforated sheets are placed one above the other, it is not possible to align the polygonal openings and fit one into another, seating and thereby reducing the effective thickness of the multiple sheets (20).
    [0107] it preferably has a compression field or resistance to compaction (i.e., permanent deformation under a compression weight) not greater than 8%. Ideally, however, there is essentially no compression field in its use.
    [0108]
    [0109] The expanded and perforated sheet of the material (20) is formed by tensioning sheets of grooved material (10) on wide wheels of different diameters placed in such a way that the outlet of the sheet of material can be regulated to an additional width between 50% and 100% of the width of the initial material sheet, so as to ensure that the resulting openings form a plurality of polygonal openings (22) as described above.
    [0110]
    [0111] The expanded and perforated sheet material (20) desirably has a surface area per unit volume from at least 4,200 times the contact surface of the liquids / vapors, polluting or non-polluting emissions, liquids, hydrocarbons contained in the closed containers of any type including pipes, tanks, cisterns particularly to inhibit, suppress, reduce, the ebullition of liquids and preferably increase 4,200 times the contact surface of the liquids / vapors and flammable gases contained in the closed containers or means of transport of said products such as hydrocarbons, gases, liquids, polluting or non-polluting emissions.
    [0112]
    [0113] The term "contact surface" refers to the surface area of the container container that is in contact with the gaseous phase, aerosol or vaporization of hydrocarbons, gases, liquids, polluting or non-polluting emissions contained in the container, tank, chimney, gas pipelines, etc.
    [0114]
    [0115] Normally, flammable liquids (liquid, vapor, aerosol or gas) are in contact with areas of the surface of the walls of the container where the flammable fluid, combustion, hydrocarbons and the insertion of the sheets of finished material, expanded and perforated the surface area in contact with the liquid and flammable gases increases at least about 4,200 times the contact surface area, preferably at least about 4,200 times this contact surface area.
    [0116]
    [0117] In one embodiment, the expanded and perforated sheet of the material (20) which is used in the present invention, and which is illustrated in (Figure number 13) as an example, may be outer generally spheroidal.
    [0118]
    [0119] The internal configuration of the body (100), generally spheroidal, comprises at least one strip of the sheet expanded and perforated of the material mentioned above, which is bent and / or curled and recessed to form said spheroidal shape.
    [0120]
    [0121] The generally spheroidal shape can be formed by using a section of the expanded and perforated sheet of material of a proportional size about 20% of the width of the expanded and perforated sheet of material.
    [0122]
    [0123] The external spherical perimeter of the spheroid (100) encloses a volume and the area of the surface of the material contained within that spherical perimeter, that is, within the spheroid (100), subject to the design requirements of the application, is of less than 1.5 square cm per cubic cm of said volume or wider if required. The surface area of the material must be at least 4,200 times the contact surface of liquid and gases contained in the container enclosing the flammable fluid, in particular to inhibit, suppress, reduce, liquid or polluting or non-polluting emissions.
    [0124]
    [0125] Preferably, the spheroid (100) has a field of compression or resistance to compaction, that is, permanent deformation under compression, not exceeding 8%.
    [0126]
    [0127] The structural strength of the final product can be modified according to the thermal treatment used in the manufacturing process of the raw material.
    [0128]
    [0129] In an alternative embodiment of this invention, the expanded and perforated sheet of the material (20) used in this invention, as illustrated in Figures 10, 11 and 12 at the exemplary rung, is provided with a corrugated transverse or sinusoidal wave (42) formed in the and the sheet of material (40) corrugated, expanded, perforated, being introduced helically in a cylindrical shape. The cylindrical shape is generally circular in cross section, and generally rectangular in longitudinal section, and in a later version of this cylindrical presentation, a sheet of flat, expanded, perforated material must be bent into the cylindrical shape. In a new form, the sheet of perforated material must be folded into the cylindrical shape, in such a way that depositions of sheets of the expanded and flattened or corrugated material are formed in the cylindrical form.
    [0130] (40) helically folded, the undulation (42) causes an increase in the effective diameter of the cylinder and thus, the area of the effective surface contained within a given external spherical perimeter of the cylinder increases, providing a wide volume inclusion in cylinders with low mass and high internal effective area.
    [0131]
    [0132] It is desirable that the cylinder has a compression field, or resistance to compaction, that is, permanent deformation under compression, not exceeding 8%, and, however, ideally, during use there is essentially no compression field .
    [0133]
    [0134] The non-perforated material sheet (1), from which it is split, must be provided as a continuous, non-perforated web of material sheet, and then, the rectangular openings (12), or slots, are formed in the continuous network in the configuration described above, as they can be rajas, and in that case, the slotted network (10) must be transversally expanded by transversally tensioning the sheet of material (10), as above a wheel placed in such a way as to regulate the exit of the sheet of material with an additional width of 50% to 100% of the width of the raw material sheet, so as to ensure that the resulting holes form a plurality of polygonal openings (22) with irregularity, such as it has been previously cited.
    [0135]
    [0136] The aforementioned, is achieved by adjusting the position and tension of the expansion wheel of the production machine, and in doing so, the result is the ability to have the walls of the finished panel model more or less erect and, therefore, increase the compression force of the perforated sheet of expanded expanded material (20).
    [0137]
    [0138] Optionally, the expanded and pierced net (20) may have a transverse sinusoidal sling (42) formed therein and the shape of the sling (42) is introduced or impressed into the lengths of the material sheet (20) as a series of curls or slings (42) transverse along the length of the net that look deep when the finished product is coiled.
    [0139]
    [0140] The cylindrical shapes can be made by spherical rolling of the sheets of expanded and perforated material discussed above.
    [0141]
    [0142] The spheroidal shapes (100) can be made by feeding the sheets of the material (20) to which a plurality of arcs with a plurality of parallel openings (22) have been provided, said sheet within a machine having a mechanical device comprising two concave semicircular sections that work in opposition to one another, and these concave sections (the mobile unit and the one covering it, fixed opposite concave) may have a variable radius with a concave work edge.
    [0143]
    [0144] The central part of the wheel-shaped contraption with the outer part similar to the rim of a bicycle, rolls 360 ° with a working edge concave with a friction surface, and the rotation of the feeding sheet in the form of circular tubular cylinder against the rough surface of the opposing mechanical devices, the movable central unit and the fixed external one, causing the material fed in the form of a cylindrical tube to coil and exit in spheroidal form.
    [0145]
    [0146] It will be understood that the term any pressure at pressures of any range without limitation. The word high pressure refers to a pressure higher than the atmospheric pressure, typically several multiples of atmospheric pressure, and that the term low temperature refers to temperatures lower than the usual atmospheric temperature, typically temperatures below -20 ° C. , or tens or hundreds of degrees below this temperature.
    [0147]
    [0148] These conditions of pressure and temperature allow certain substances that remain in a gaseous state in conditions of pressure and atmospheric temperature can be stored and transport in the liquid state and therefore occupying a much lower volume, making transport much more efficient.
    [0149]
    [0150] The proposed tank truck comprises, in a usual way in the sector:
    [0151] S is a sealed inner compartment, defined by interior walls, resistant to high pressures, said inner compartment having a sealed cylindrical section at its two opposite ends, spherical or rounded caps, said cylindrical section defining at its center an axis of the longitudinal tank truck lying on transport direction filled with anti-explosive alloys.
    [0152]
    [0153] S is a watertight outer compartment, defined by exterior walls, which houses inside the interior compartment, the interior walls of the interior compartment being spaced from the outer walls of the exterior compartment defining between said interior and exterior walls a chamber.
    [0154] where the outer walls of said outer compartment are parallel to the interior walls of the interior compartment in most of the tank truck.
    [0155]
    [0156] The proposed tank truck includes, in addition:
    [0157] S a chassis attached to the sealed outer compartment of said tank truck;
    [0158] S at least two pairs of wheels facing their axes perpendicular to the direction of transport, said wheels having the same diameter and said wheels being coupled to said chassis by means of a suspension system, defining the axes of said wheels, under a uniform inflation and When the vehicle is on a flat floor, a chassis support plane, and
    [0159] S means of anchoring the tank to a tractor, engine, truck cab with said anchoring means located under the outer compartment of the truck in its front half and connected to a tractor, truck engine.
    [0160] S Can:
    [0161] o The deposit inside the tank can be distributed throughout the truck.
    [0162] The tank trucks could be located both inside and above the chassis of the truck and / or by any model, design of installation and incorporation of the tank both laterally, inferiorly, horizontally, vertically and even being able to be located in the ceilings, roofs of the wagons of merchants, passengers.
    [0163] o Tanks tanks can be connected to more than one engine and operate individually, dual, auxiliary.
    [0164] o The tank, tank within the tank truck can have an angle of inclination of between 0.01% -15% if said angle of inclination is required to improve the use of hydrocarbons, reasons of load distribution in the chassis or for aerodynamic reasons . o This possibility of inclining the tanks can be done according to the design and final location of the tanks filled with the alloy in the form of mesh / spheres.
    [0165]
    [0166] As it would be obvious to the expert, between the interior and exterior compartments there will be supports and anchors that allow to support the interior compartment inside the outer compartment and separated from it, said supports and anchors being designed to avoid the creation of algae bridges between both compartments.
    [0167]
    [0168] The total or partial watt maintained in said chamber will be filled with the alloys in mesh format and / or anti-algae spheres will perform the algae and anti-explosive insulation functions that gas, liquefied during transport without requiring refrigeration equipment and without the possibility of explosion externally and / or internally even by penetration of explosive, incendiary and / or penetrating bullets in the most extreme cases.
    [0169]
    [0170] The chassis supports at least two pairs of wheels in its rear half, connected to the chassis by means of a usual suspension system of the usual type. Each pair of wheels are arranged symmetrically on opposite sides of the tank truck and, in conditions on wheels by a signature, their respective axes are coaxial. The successive pairs of wheels have identical disposition and are with their respective axes parallel to the wheel axes described, jointly defining a chassis plane that ideally will be parallel to the flat ground on which the wheels are seated.
    [0171]
    [0172] The present invention also proposes that the tanker axle forms, in the direction of transport, a recommended angle, but does not limit itself by increasing or reducing its angle laterally, vertically and / or horizontally between 0.01 ° and 15 °. ° with respect to said chassis support plane, so that the rear and / or front, side portion of the tank truck is at a level lower or higher than the front portion thereof

    [0174] These recommended characteristics allow the rear end of the tank truck to be placed in a lower position than the usual one in the sector, which in turn has a decrease in the center of gravity of the tank without having to reduce its capacity and without modifying the height of the means of anchoring the truck on which the tank truck is supported. The descent of the center of gravity has an effect on a greater stability of the tank truck during its transport, and therefore a safer transport and even more filling of the alloys of this invention which drastically reduces the algae, the water hammer and the possibility of explosion.
    [0175]
    [0176] According to an additional embodiment, said chassis includes at least two parallel and facing structural bars between which the outer compartment of the tank truck is partially housed. This makes it possible to reduce the distance between the rear part of the tank-truck and the flat floor, partially fitting it into the chassis, thus reducing! the center of gravity of the entire truck chassis. In the present example, the free distance between these two structural bars is greater than 1300mm, for example, 1400mm.
    [0177] plane of support of chassis, and parallel to the axis of cistern
    [0178]
    [0179] As will be understood the position of said parallel structural bars with respect to the chassis support plane will be given in the described conditions in which the wheel load of all the wheels is identical and the trailer is on a flat floor and coupled to a machine , engine, tractor unit Being different conditions the wheel suspension system would modify the position of the axes of the wheels, alternating the reference of the support plane of the chassis. However, in such a case, the support plane of the chassis obtained under the conditions initially described would be maintained, even if the position of the axes of the wheels is modified.
    [0180]
    [0181] According to another proposed additional or alternative embodiment of the tank truck, the chassis includes at least two facing cradle structural elements between which the outer compartment of the tank truck is partially housed, each structural element in cradle including at least one upper edge parallel to the axis of the tank. cistern, and at least one lower edge parallel to the chassis support plane. These structural elements in cradle allow connecting the rest of the chassis and the wheels to the tank truck defining the aforementioned inclination greater than 0.01 ° thanks to its geometry in cradle. Said cradle structural elements can be a continuous element disposed on each side of the cryogenic cistern, or they can be a succession of spacers of different heights located on either side of the cryogenic cistern which, together, define said two structural elements in cradle faced.
    [0182]
    [0183] The structural elements in the cradle can be combined with the aforementioned two parallel bars facing each other.
    [0184]
    [0185] It is also proposed that the tanker truck by means of said anchoring means and on the said flat floor, the lowest point of the outer compartment of the tank truck, in the truck chassis, without limiting itself, but recommending that it be less than 150 cm. said flat floor, preferably less than 110 cm.
    [0186]
    [0187] Preferably the tank truck will have a length equal to or greater than 15 meters, but the use of a tank-truck is not limited in order to have the possibility of incorporating smaller tanks inside the tank truck itself and even having tanks distributed throughout the truck. according to the operational needs.
    [0188] perpendicular, tangent, etc. they admit slight deviations with respect to the theoretical position defined by said nomenclature.
    [0189]
    [0190] It will also be understood that any range of values offered may not be optimal in their extreme values and may require adaptations of the invention for said extreme values to be applicable, said adaptations being within the reach of a person skilled in the art.

    [0246]
    [0247] Example of realization:
    [0248] The alloy in the form of mesh or spheres that is incorporated in the compartment or structure of the cistern, is formed by the body of the alloy. This is formed by sheets of perforated material, are expanded sheet and perforated material (20) that is used in the present invention, and which is illustrated in (Figure number 13) as an example, can be configured as a form comprising a body (100) with an external generally spheroidal shape or configuration.
    [0249]
    [0250] The internal configuration of the body (100), generally spheroidal, comprises at least one strip of the expanded and perforated sheet of the material mentioned above, which is bent and / or curled and recessed to form said spheroidal shape.
    [0251]
    [0252] The generally spheroidal shape can be formed by using a section of the expanded and perforated sheet of material of a proportional size about 20% of the width of the expanded and perforated sheet of material.
    [0253] of the material contained within that spherical perimeter, that is, within the spheroid (100), subject to the design requirements of the application, is at least 1.5 square cm per cubic cm of said volume or wider if required. The surface area of the material must be at least 4,200 times the contact surface of flammable fluids contained in the container / tank enclosing / supporting / containing the flammable fluid, in particular to inhibit, suppress, reduce, fluids or pollutant emissions or non-polluting.
    [0254]
    [0255] Preferably, the spheroid (100) has a field of compression or resistance to compaction, that is, permanent deformation under compression, not exceeding 8%.
    [0256] The structural strength of the final product can be modified according to the thermal treatment used in the manufacturing process of the raw material.
    [0257]
    [0258] In an alternative embodiment of this invention, the expanded and perforated sheet of the material (20) used in this invention, as illustrated in Figures 10, 11 and 12 at the exemplary rung, is provided with a corrugated transverse or sinusoidal wave (42) formed in the and the sheet of material (40) corrugated, expanded, perforated, being introduced helically in a cylindrical shape. The cylindrical shape is generally circular in cross section, and generally rectangular in longitudinal section, and in a later version of this cylindrical presentation, a sheet of flat, expanded, perforated material must be bent into the cylindrical shape. In a new form, the sheet of perforated material must be folded into the cylindrical shape, in such a way that depositions of sheets of the expanded and flattened or corrugated material are formed in the cylindrical form.
    [0259]
    [0260] Due to the ripple (42) formed in the material sheet (40), with the sheet of material (40) folded helically, the ripple (42) causes an increase in the effective diameter of the cylinder and thus increases the area of the effective surface contained within a given external spherical perimeter of the cylinder, providing a wide volume inclusion in the cylinders with low mass and high internal effective area.
    [0261]
    [0262] It is desirable that the cylinder has a compression field, or resistance to compaction, that is, permanent deformation under compression, not exceeding 8%, and, however, ideally, during use there is essentially no compression field .
    [0263] provided as a continuous, non-perforated network of sheet material, and then, the rectangular openings (12), or slots, are formed in the continuous network in the configuration described above, such as slits, and in that case, the slotted net (10) must be transversally expanded by transversally tensioning the sheet of material (10), such as above a wheel placed in such a way as to regulate the exit of the sheet of material with an additional width of 50% to 100% of the width of the sheet of raw material, so as to ensure that the resulting holes form a plurality of polygonal openings (22) with irregularity, as mentioned above. Also with the possibility of expanding said material by passing it through rubber wheels that increase their separation with the desired width.
    [0264]
    [0265] The aforementioned, is achieved by adjusting the position and tension of the expansion wheel of the production machine, and in doing so, the result is the ability to have the walls of the finished panel model more or less erect and, therefore, increase the compression force of the perforated sheet of expanded expanded material (20).
    [0266]
    [0267] Optionally, the expanded and pierced net (20) may have a transverse sinusoidal sling (42) formed therein and the shape of the sling (42) is introduced or impressed into the lengths of the material sheet (20) as a series of curls or slings (42) transverse along the length of the net that look deep when the finished product is coiled.
    [0268]
    [0269] The cylindrical shapes can be made by spherical rolling of the sheets of expanded and perforated material discussed above.
    [0270]
    [0271] The spheroidal shapes (100) can be made by feeding the sheets of the material (20) to which there are provided pluralities of arcs with a plurality of parallel openings (22), of which the longitudinal center is parallel to the central longitudinal axis of the laminate, introducing said sheet into a machine having a mechanical device comprising two concave semicircular sections that work in opposition to one another, and these concave sections (the mobile unit and the one covering it, fixed opposite concave) may have a variable radius with a concave working edge.
    [0272] Stainless steel, aluminum, plastic fibers of any size or uses, are characterized by the fact that it comprises the following phases:
    [0273]
    [0274] - Fabrication, by means of drawing, of the two steel half-shells (1a) and (1b), one of which has a hole (1c) in which the fitting is welded.
    [0275]
    [0276] - Introduction of the diffuser element (3) inside the bottle (1) through its introduction in the form of rolls of mesh placed inside each of the half-bodies at the time prior to the realization of the joint welds same.
    [0277]
    [0278] - Application of welding points with the corresponding tooling.
    [0279]
    [0280] - Process of annealing in furnace to relieve it.
    [0281]
    [0282] Figures 15, 16 and 17 show an embodiment with nonlimiting illustrative character of a trailer with anti-explosive properties for transport of cryogenic fluids at high pressure and low temperature by dragging in a transport direction by a tractor truck as shown in Fig.15, the direction of transport being the direction of advance of the tractor truck.
    [0283]
    [0284] The tractor truck will be of the usual type for the transport of trailers and sema-trailers, formed by a cabin and by a rear platform on which to bear part of the weight of the trailer or sema-trailer to be transported.
    [0285]
    [0286] The trailer shown in the present embodiment (Fig. 15 and 16) consists of a cryogenic tank filled with anti-explosive alloys in mesh / spheres format formed by an outer compartment 12, defined by an outer wall, which contains an interior compartment 11, defined by an inner wall, the outer and inner walls of both the outer 12 and inner 11 compartments being separated and spaced apart by spaced-apart spacing so as to reduce the thermal transmission therethrough. The space between both compartments constitutes an insulating chamber 13 filled with anti-explosive alloys. This nested construction of two compartments is shown in the section of Fig.16.
    [0287] cryogenic state without the possibility of explosion. In order to achieve this resistance with a low weight, the geometry of the inner compartment 11 is optimized, which is proposed to consist of a cylindrical body of approximately 235 cm in diameter and approximately 18 meters in length defining at its center an axis of cistern E, the cylindrical body being closed at both ends by rounded caps. The result is an elongated compartment with high resistance to internal pressure.
    [0288]
    [0289] The outer compartment 12 completely envelops said inner compartment 11, reproducing its geometry, but with a larger size, its outer walls being parallel to the inner walls of the inner compartment 11 in the majority of said outer compartment 12, for example, to between 5 and 10 cm away.
    [0290]
    [0291] Under said cryogenic cistern 10, an anchoring means 40 for the articulated fixation and towing of the trailer by a tractor truck is fixed in its previous half. This type of anchoring means 40 are standardized and are those commonly used in all trailers of this type. Typically, they consist of a vertical descendant teat terminated by a projection attached to the trailer, and a pivoting platform equipped with a cradle-shaped center that culminates in a housing complementary to said projection of the vertical teton.
    [0292]
    [0293] Under the rear half of the trailer, in the transport direction, a chassis 20 is located which, in the present embodiment, consists of two parallel structural bars 21, for example, two normalized profiles with I or C section joined to opposite sides. of the rear half of the outside of the outer compartment 12, said outer compartment 12 being partially housed between said two parallel structural bars 21.
    [0294]
    [0295] The connection between each of the parallel structural bars 21 and the outer compartment 12 is produced by a cradle structural element 22, consisting of an element of increasing section in the transport direction. Said cradle structural element 22 is welded to the outer compartment 12 at its upper end along a line parallel to the cistern axis E, and is bonded to the corresponding structural bar 21 at its lower end along its length. As the cradle structural element 22 of increasing section, the two parallel structural bars 21 are not parallel to the cistern axis E, but form an angle equal to the inclination of the cradle structural element 22. In this example the aforementioned inclination is of 2, 54 °.
    [0296] the suspension systems of three pairs of parallel wheels 30 anchor, with three wheels 30 arranged on each side of the trailer, in its rear half. The six wheels 30 will be identical and, under conditions of equal pressure and on a flat floor, the trailer being supported on a tractor truck by its anchoring means 40, the axes of the wheels 30 will define a support plane of chassis P.
    [0297]
    [0298] In the present embodiment the inclination of the two structural bars 21 parallel to the tank axis E has been calculated so that said two structural bars 21 are parallel to the support plane of the chassis P under the indicated conditions.
    [0299]
    [0300] As a result of the described characteristics, a trailer is obtained that includes a cryogenic tank 10 with its rear end lower than its front end, under transport conditions, with the lowest point of said cistern being less than 90 cm from the flat floor. This reduces the center of gravity of the trailer, offering safer transport conditions.
    [0301]
    [0302] Another embodiment not shown contemplates that the two parallel structural bars 21 are welded directly to the outer compartment 12 in a position parallel to the cistern axis E, and that under said structural bars 21 the cradle structural elements 22 are welded which will be increased in the direction Of transport. To said cradle structural elements 22 the rest of the chassis and the suspension systems of the wheels 30 would be joined. In this case the structural bars 21 would be parallel to the cistern axis E, and not to the support plane of the chassis P.
    [0303]
    [0304] In a further embodiment not shown, it is proposed to dispense with the structural bars 21 and to use only the cradle structural elements 22 of increasing section in the transport direction.
    [0305]
    [0306] As it is evident, the trailer will include other elements to allow the safe filling and emptying of the cryogenic cistern, such as conduit systems, valves, etc., thus! as security elements for transport, such as bumpers, lights, signals, etc.
