Description

La présente invention a pour objet un container étanche pour le transport de produits, en particulier du bitume, fabriqués et chargés à l'état liquide ou pâteux et se solidifiant à température ambiante et pouvant être liquéfiés ou rendus pâteux sous l'action de la chaleur, ce container étant pourvu d'au moins un orifice de remplissage et de vidange et de moyens de fermeture étanches de cet orificeThe present invention relates to a sealed container for the transport of products, in particular bitumen, manufactured and loaded in the liquid or pasty state and solidifying at room temperature and which can be liquefied or made pasty under the action of heat. , this container being provided with at least one filling and emptying orifice and watertight closing means of this orifice

Jusqu'à présent, on utilise, pour le transport du bitume à l'état solide, des fûts que l'on soumet, pour en extraire le bitume, à une source de chaleur externe ou desquels on dégage le bitume à l'état solide.Hitherto, drums have been used for the transport of bitumen in the solid state, which are subjected, to extract the bitumen, to an external heat source or from which the bitumen is released in the solid state. .

L'usage de ces fûts présente de multiples inconvénients qui se situent tant au niveau de leur manutention et de leur transport qu'au niveau de la récupération du produit solide qu'ils contiennent.The use of these drums has multiple drawbacks which lie both in their handling and transport and in the recovery of the solid product they contain.

En ce qui concerne la manutention et le transport des fûts, ceux-ci réclament beaucoup de main- d'oeuvre du fait de la capacité réduite des fûts et de la nécessité qu'il en résulte de les stocker au moment de leur remplissage et en cours de transport, à chaque fois qu'un transbordement se produit. De plus, ces divers stockages et transbordements, outre la main d'oeuvre, nécessitent du temps et des appareillages appropriés à la manutention desdits fûts. Enfin, ces opérations multiples accroissent les dangers de détérioration, par choc ou chute, des fûts et la perte du produit qu'ils contiennent.With regard to the handling and transport of the drums, they require a lot of manpower due to the reduced capacity of the drums and the resulting need to store them when they are filled and in during transport, whenever a transhipment occurs. In addition, these various storage and transhipments, in addition to labor, require time and appropriate equipment for handling said drums. Finally, these operations multiple increases the danger of deterioration, shock or fall, drums and loss of the product they contain.

Au moment de la récupération du produit solide transporté en fûts, on porte ces derniers à une température suffisante pour liquéfier le bitume à l'aide d'une source de chaleur externe qui réchauffe tant bien que mal la masse de bitume contenue dans les fûts, avec des risques non négligeables de dégradation du bitume dus à des surchauffes locales et de contamination du bitume par une flamme nue. Cette façon de faire présente en outre l'inconvénient sérieux, d'une part, de nécessiter un apport considérable de calories dont une faible partie seulement est utilisée réellement pour réchauffer le bitume et, d'autre part, d'entraîner une perte d'environ 2 à 3 % du contenu des fûts par adhérence du bitume aux parois de ces derniers.When recovering the solid product transported in barrels, the latter are brought to a temperature sufficient to liquefy the bitumen using an external heat source which somehow heats up the mass of bitumen contained in the barrels, with significant risks of degradation of the bitumen due to local overheating and contamination of the bitumen by an open flame. This procedure also has the serious drawback, on the one hand, of requiring a considerable intake of calories of which only a small part is actually used to heat the bitumen and, on the other hand, of causing a loss of approximately 2 to 3% of the contents of the barrels by adhesion of the bitumen to the walls of the latter.

Enfin, les fûts, vidés de leur contenu, présentent l'inconvénient de ne pouvoir être réutilisé et de ne présenter qu'une valeur marchande négligeable.Finally, the barrels, emptied of their contents, have the drawback of not being able to be reused and of presenting only a negligible market value.

L'invention a pour but de remédier à ces inconvénients et de procurer un container, en particulier un container pour le transport de bitume, qui permet de réduire dans des proportions importantes, tant au niveau de son remplissage, de sa manutention et de son transport, les opérations qui seraient nécessaires pour transporter une même quantité de bitume dans des fûts. L'usage du container suivant l'invention offre l'avantage, par rapport aux fûts, de ne réclamer, pour réchauffer le bitume qu'il contient, que moins de 25 % de la quantité d'huile combustible qui serait nécessaire pour réchauffer une même quantité de bitume en fûts, tout en permettant la liquéfaction rapide du bitume sans dégradation ou contamination de celui-ci. Ce container permet également de réduire la perte de bitume, par adhérence aux parois, d'environ une tonne par rapport à la même quantité de bitume transportée en fûts. Parmi les autres avantages procurés par ce container, il y a lieu de noter que, contrairement aux fûts, il peut être réutilisé à diverses fins , telles que réservoir, enceinte de stockage, coffrage perdu pour béton lors de la réalisation de quais, d'appontements, etc... En cours de transport, sa construction et le mode de transport des containers le mettent à l'abri des dégradations auxquelles sont généralement soumises les fûts, tandis que son volume et son poids permettent d'éviter les vols et pertes qui sont fréquents lors de l'utilisation des fûts.The invention aims to remedy these drawbacks and to provide a container, in particular a container for the transport of bitumen, which makes it possible to reduce in significant proportions, both in terms of its filling, its handling and its transport. , the operations that would be necessary to transport the same quantity of bitumen in drums. The use of the container according to the invention offers the advantage, compared with drums, of claiming, in order to reheat the bitumen it contains, only less than 25% of the quantity of combustible oil which would be necessary to reheat a same amount of bitumen in barrels, while allowing the rapid liquefaction of bitumen without degradation or contamination thereof. This container also makes it possible to reduce the loss of bitumen, by adhesion to the walls, by about one ton compared to the same amount of bitumen transported in drums. Among the other advantages provided by this container, it should be noted that, unlike drums, it can be reused for various purposes, such as tank, storage enclosure, formwork lost for concrete during the construction of docks, landing stages, etc. ... During transport, its construction and the mode of transport of the containers protect it from damage to which drums are generally subjected, while its volume and its weight make it possible to avoid theft and loss. which are common when using barrels.

Si le coût d'un container suivant l'invention est supérieur d'environ 20 % au coût des fûts permettant de transporter la même quantité de bitume, cette différence de coût est toutefois largement inférieure aux économies réalisées au niveau de la manutention et du transport du container et au niveau de l'extraction du bitume de ce dernier. En outre, vide, ledit container a encore une valeur marchande non négligeable qui compense pratiquement la différence de coût précitée.If the cost of a container according to the invention is approximately 20% higher than the cost of drums allowing the same amount of bitumen to be transported, this difference in cost is however much less than the savings made in handling and transport. of the container and at the bitumen extraction level. In addition, empty, said container still has a non-negligible market value which practically compensates for the above-mentioned cost difference.

A cet effet, suivant l'invention, ledit container comprend des moyens disposés à l'intérieur du container et agencés pour transmettre des calories, fournies par une source de chaleur externe, à la masse de produit enfermée dans le container afin de liquéfier cette dernière pour que le produit puisse s'écouler par gravité par l'orifice de vidange susdit.To this end, according to the invention, said container comprises means arranged inside the container and arranged to transmit calories, supplied by an external heat source, to the mass of product enclosed in the container in order to liquefy the latter. so that the product can flow through gravity through the aforementioned drain opening.

Suivant une forme de réalisation de l'invention, les moyens susdits, disposés à l'intérieur du container pour transmettre les calories à la masse, sont constitués par un serpentin dont les deux extrémités se raccordent à des orifices prévus dans les parois du container.According to one embodiment of the invention, the aforementioned means, arranged inside the container for transmitting calories to the mass, are constituted by a coil whose two ends are connected to orifices provided in the walls of the container.

Suivant un mode de réalisation avantageux de l'invention, le container comprend, à une des extrémités du serpentin, des moyens agencés pour permettre le reccor- dement audit serpentin d'un brûleur à huile combustible ou à gaz liquéfié.According to an advantageous embodiment of the invention, the container comprises, at one end of the coil, means arranged to allow the refitting of said fuel oil or liquefied gas burner to said coil.

Suivant une forme de réalisation particulièrement avantageux de l'invention, le serpentin est agencé à proximité de la base du container, sensiblement parallèlement à cette dernière et au moins une partie des branches du serpentin s'étendent à proximité des parois latérales du container, sensiblement parallèlement à ces dernières et sur une partie importante de leur longueur.According to a particularly advantageous embodiment of the invention, the coil is arranged near the base of the container, substantially parallel to the latter and at least a part of the branches of the coil extend near the side walls of the container, substantially parallel to these and over a significant part of their length.

D'autres détails et particularités de l'invention ressortiront de la description des dessins annexés au présent mémoire et qui représentent, à tire d'exemple non limitatif, une forme de réalisation particulière du container suivant l'invention,Other details and particularities of the invention will emerge from the description of the drawings appended to this specification and which represent, by way of nonlimiting example, a particular embodiment of the container according to the invention,

La figure 1 est une vue en perspective, avec brisures partielles, du container suivant l'invention.Figure 1 is a perspective view, partially broken, of the container according to the invention.

La figure 2 est une vue analogue à la figure 1 montrant des détails dudit container.Figure 2 is a view similar to Figure 1 showing details of said container.

Dans les différentes figures, les mêmes notations de référence désignent des éléments identiques ou analogues.In the different figures, the same reference notations designate identical or analogous elements.

Le container 1 suivant l'invention et représenté aux dessins est un container étanche destiné au transport de produits, tel que le bitume, fabriqués et chargés à l'état liquide et se solidifiant à la température ambiante, ces produits pouvant être amenés de l'état solide à l'état liquide par un apport de calories. Ce container, d'une capacité standard d'environ 35 m , permet le transport de l'ordre de 20 tonnes de bitume, ce qui correspond au chargement d'environ 125 fûts traditionnels. Ce container 1, qui est constitué d'un châssis 2 et d'une base 3 indéformables en acier et de parois latérales 4 et supérieure 5 en tôle nervurée, comprend des moyens 6 disposés à l'intérieur du container et agencés pour transmettre des calories, fournies par une source de chaleur externe, à la masse de bitume qui y est enfermée pour liquéfier cette masse afin que le bitume puisse s'écouler par gravité par l'orifice de vidange 7 du container, l'orifice de remplissage 8 de ce dernier étant ménagé dans la face supérieure 5, les dimensions de cet orifice 8 étant telles qu'il permet le passage d'un homme, lesdits orifices 7 et 8 étant respectivement pourvus de moyens de fermeture 9 et 10.The container 1 according to the invention and shown in the drawings is a sealed container intended for the transport of products, such as bitumen, manufactured and loaded in the liquid state and solidifying at ambient temperature, these products being able to be brought from the solid state in liquid state by an intake of calories. This container, with a standard capacity of around 35 m, allows the transport of around 20 tonnes of bitumen, which corresponds to the loading of around 125 traditional drums. This container 1, which consists of a frame 2 and a non-deformable base 3 of steel and of side walls 4 and upper 5 made of ribbed sheet metal, comprises means 6 arranged inside the container and arranged to transmit calories , supplied by an external heat source, to the mass of bitumen which is enclosed therein to liquefy this mass so that the bitumen can flow by gravity through the emptying orifice 7 of the container, the filling orifice 8 of this the latter being formed in the upper face 5, the dimensions of this orifice 8 being such that it allows the passage of a man, said orifices 7 and 8 being respectively provided with closing means 9 and 10.

Les moyens 6 sont constitués par un serpentin 11 dont les extrémités 12 et 13 se raccordent à des orifices 14 et 15 prévus dans deux parois opposées du container, ce serpentin 11 est agencé à proximité de la base dudit container, sensiblement parallèlement à cette dernière, et une partie importante de ses branches s'étendent à proximité des parois latérales dudit container, sensiblement parallèlement à celles-ci et sur une partie importante de leur longueur. Les orifices 14 et 15 sont agencés pour pouvoir être obturés, par exemple par des bouchons filetés 16, afin d'isoler le serpentin pendant la manutention et le transport du container, l'orifice 14 étant en outre agencé pour que l'on puisse, comme montré à la figure 2, y raccorder un brûleur 17 à huile combustible ou à gaz liquéfié, l'orifice 15 présentant avantageusement des moyens de raccordement d'une cheminée d'évacuation des gaz de combustion du brûleur ou d'une tubulure permettant le raccordement du container à l'orifice 14 d'un second container pour que les gaz de combustion circulent dans le serpentin du second container après avoir circulé dans celui du premier container, le brûleur 17 pouvant alors être utilisé pour réchauffer le contenu de plusieurs containers disposés en batterie. Les orifices 14 et 15 ainsi que l'orifice de vidange 7, disposé au voisinage de l'orifice 14, sont réalisés dans le châssis et à la base du container et le serpentin 11 s'étend à proximité de cette base 3 et des parois latérales pour, d'une part, que la partie inférieure de la masse soit rapidement portée à la température de liquéfaction du bitume par les gaz chauds circulant dans le serpentin et par conduction et, d'autre part, pour que les parois latérales s'échauffent à un point tel que le bitume en contact avec les parois se liquéfie et se détache de ces dernières de sorte que la masse de bitume encore solidifiée soit libérée et descende, par gravité, vers le serpentin 11 pour recevoir les calories nécessaires à sa liquéfactioncomplète. La distance qui sépare les branches du serpentin de la base et des parois du container, la capacité du gicleur du brûleur et la section du serpentin sont calculées de manière à ce que la température atteinte dans les zones comprises entre lesdites branches du serpentin et les parois du container soit inférieure à la température de cokéfaction du bitume. L'orifice de vidange 7 est pourvu d'un organe de fermeture pour le transport et est agencé pour recevoir une vanne 18 permettant de commander l' écoulement du bitume liquéfié, le container présentant avantageusement un logement 19, obturable en cours de transport et disposé à proximité de l'orifice de vidange 7, destiné à recevoir une sonde, un indicateur de température 20 étant, comme montré à la figure 2, associé à cette sonde et permettant de contrôler la température du bitume dans le voisinage de l'orifice de vidange 7.The means 6 consist of a coil 11, the ends 12 and 13 of which are connected to orifices 14 and 15 provided in two opposite walls of the container, this coil 11 is arranged near the base of said container, substantially parallel to the latter, and a large part of its branches extend near the side walls of said container, substantially parallel to these and over a large part of their length. The orifices 14 and 15 are arranged to be able to be closed, for example by threaded plugs 16, in order to isolate the coil during handling and transport of the container, the orifice 14 being further arranged so that, as shown in FIG. 2, connect there a burner 17 with combustible oil or liquefied gas, the orifice 15 advantageously having means for connecting a chimney for evacuating the combustion gases from the burner or a pipe allowing the connection of the container at the orifice 14 of a second container so that the combustion gases circulate in the coil of the second container after having circulated in that of the first container, the burner 17 can then be used to heat the content of several containers arranged in a battery . The orifices 14 and 15 as well as the drain orifice 7, disposed in the vicinity of the orifice 14, are produced in the frame and at the base of the container and the coil 11 extends near this base 3 and the walls lateral for, on the one hand, that the lower part of the mass is quickly brought to the liquefaction temperature of the bitumen by the hot gases circulating in the coil and by conduction and, on the other hand, so that the lateral walls heat up to a point such that the bitumen in contact with the walls liquefies and detaches from the latter so that the mass of bitumen still solidified is released and descends, by gravity, to the coil 11 to receive the calories necessary for its complete liquefaction . The distance between the branches of the coil from the base and the walls of the container, the capacity of the burner nozzle and the section of the coil are calculated so that the temperature reached in the areas between said branches of the coil and the walls of the container is lower than the coking temperature of the bitumen. The drain orifice 7 is provided with a closure member for transport and is arranged to receive a valve 18 making it possible to control the flow of liquefied bitumen, the container advantageously having a housing 19, closable during transport and disposed near the drain orifice 7, intended to receive a probe, a temperature indicator 20 being, as shown in FIG. 2, associated with this probe and making it possible to control the temperature of the bitumen in the vicinity of the orifice of drain 7.

Pour un container de la capacité susdite, le diamètre du tube constituant le serpentin est de l'ordre de 219 mm, la distance séparant les branches du serpentin, s'étendant sensiblement en forme de N, des fond et parois du container n'étant pas inférieure à 10 cm et ce, pour un brûleur d'une capacité de 110.000 KCal/h, le temps requis pour porter le contenu du container à la température d'environ 160°C, qui permet la vidange, étant comprise entre 6 et 10 heures en fonction de la température ambiante, tandis que la consommation du brûleur en gasoil est tout au plus de 150 litres.For a container of the above capacity, the diameter of the tube constituting the coil is of the order of 219 mm, the distance separating the branches of the coil, extending substantially in the form of an N, the bottom and walls of the container not being not less than 10 cm and this, for a burner with a capacity of 110,000 KCal / h, the time required to bring the contents of the container to the temperature of about 160 ° C, which allows emptying, being between 6 and 10 hours depending on the ambient temperature, while the consumption of the diesel burner is at most 150 liters.

Il doit être entendu que l'invention n'est nullement limitée à la forme de réalisation décrite et que bien des modifications peuvent être apportées à cette dernière sans sortir du cadre du présent brevet.It should be understood that the invention is in no way limited to the embodiment described and that many modifications can be made to the latter without departing from the scope of this patent.

C'est ainsi que l'on pourrait notamment prévoir un container dont le serpentin serait raccordé à une source de vapeur sous pression ou encore à une source de gaz chaud de récupération.Thus, one could in particular provide a container whose coil would be connected to a source of pressurized steam or even to a source of hot recovery gas.
