Description

La présente invention se rapporte au domaine du lavage intérieur des citernes.
   La présente invention se rapporte plus particulièrement à un dispositif de lavage pour le lavage de l'intérieur d'une citerne, et notamment d'une citerne sensiblement cylindrique de camion pour le transport de fluides, du type comportant au moins une bouche d'entrée située à l'extérieur de la citerne, en général en bas, à l'arrière, un tuyau d'acheminement, courant sur la longueur de la citerne et au moins une tête de projection située à l'intérieur de la citerne, afin de permettre de projeter à l'intérieur de la citerne le liquide de nettoyage introduit par la bouche d'entrée et acheminé par le tuyau d'acheminement.The present invention relates to the field of internal tank washing.
The present invention relates more particularly to a washing device for washing the inside of a tank, and in particular of a substantially cylindrical tank of a truck for transporting fluids, of the type comprising at least one inlet mouth. located outside the tank, generally at the bottom, at the rear, a routing pipe running along the length of the tank and at least one projection head located inside the tank, in order to allow to spray inside the tank the cleaning liquid introduced by the inlet mouth and conveyed by the conveying pipe.

L'art antérieur connaít déjà des dispositifs de lavage pour le lavage de l'intérieur des citernes comportant au moins une bouche d'entrée (3) située à l'extérieur de la citerne (2), un tuyau d'acheminement (4) et au moins une tête de projection (5) située à l'intérieur de la citerne (2). Un tuyau de montée (6) est outre parfois prévu entre la bouche d'entrée (3) et le tuyau d'acheminement (4) et un ou plusieurs tuyau(x) de descente (7) est ou sont outre parfois prévu(s) entre le tuyau d'acheminement (4) et chaque tête de projection (5).
   Dans une première variante de l'art antérieur, illustrée figure 1, le tuyau d'acheminement (4) est positionné à l'extérieur du corps de la citerne (2), c'est-à-dire au-dessus de la paroi extérieure (23) de la citerne. The prior art already knows washing devices for washing the interior of tanks comprising at least one inlet mouth (3) located outside the tank (2), a delivery pipe (4) and at least one projection head (5) located inside the tank (2). A riser pipe (6) is sometimes provided between the inlet mouth (3) and the delivery pipe (4) and one or more down pipe (s) (7) is or are sometimes provided (s) ) between the routing pipe (4) and each projection head (5).
In a first variant of the prior art, illustrated in FIG. 1, the conveying pipe (4) is positioned outside the body of the tank (2), that is to say above the wall outside (23) of the tank.

L'inconvénient majeur de cette première variante est que le tuyau d'acheminement n'est pas protégé des éléments extérieurs. Ainsi, lorsque la citerne est une citerne de camion, le tuyau d'acheminement peut être endommagé par des projections de pierres ou par une mauvaise manoeuvre du chauffeur du camion. En outre, dans cette version, le tuyau d'acheminement n'est pas protégé des déperditions de chaleur.The major disadvantage of this first variant is that the routing pipe is not protected external elements. So when the tank is a truck tank, the routing pipe can be damaged by flying stones or by wrong maneuver by the truck driver. Furthermore, in this version, the routing pipe is not protected heat loss.

Dans une deuxième variante de l'art antérieur, illustrée figure 2, le tuyau d'acheminement (4) est positionné à l'intérieur de la paroi du corps de la citerne (2), afin de le protéger des éléments extérieurs et est positionné plus précisément dans une couche d'isolation (20) ménagée entre la paroi intérieure (21) et la paroi extérieure (23) de la citerne.
   L'inconvénient majeur de cette deuxième variante est que si des problèmes d'étanchéité se posent dans le dispositif de lavage, notamment au niveau du raccord entre le tuyau d'acheminement (4) et les tuyaux de descente (7), le fluide s'échappe à l'intérieur de la couche d'isolation (20) et peut la dégrader. En outre, les réparations de tels problèmes engendrent des frais important de démontage de la structure de la citerne.In a second variant of the prior art, illustrated in FIG. 2, the conveying pipe (4) is positioned inside the wall of the body of the tank (2), in order to protect it from external elements and is positioned more precisely in an insulation layer (20) formed between the inner wall (21) and the outer wall (23) of the tank.
The major drawback of this second variant is that if sealing problems arise in the washing device, in particular at the connection between the conveying pipe (4) and the downpipes (7), the fluid s escapes inside the insulation layer (20) and can degrade it. In addition, repairs to such problems generate significant costs for dismantling the structure of the tank.

La présente invention entend remédier aux inconvénients de l'art antérieur en proposant que le tuyau d'acheminement soit à la fois protégé des éléments extérieurs, bien isolé et plus facile d'accès.The present invention intends to remedy the disadvantages of the prior art by proposing that the pipe routing is both protected from the elements exterior, well insulated and easier to access.

Pour ce faire, la présente invention est du type décrit ci-dessus et elle est remarquable, dans son acception la plus large, en ce que le tuyau d'acheminement est situé, au moins partiellement, à l'intérieur de ladite citerne. To do this, the present invention is type described above and it is remarkable, in its widest sense, in that the routing pipe is located, at least partially, inside said tank.

Ledit tuyau d'acheminement est, de préférence, constitué d'un tube principal coupé longitudinalement et positionné contre la paroi intérieure de ladite citerne, ladite paroi intérieure refermant ledit tube coupé.
   Ledit tuyau d'acheminement présente, de préférence, une section partiellement circulaire, mais il est également possible de réaliser un tuyau d'acheminement à section rectangulaire ou ovale, ... En outre, cette section peut ne pas être constante sur toute la longueur du tuyau d'acheminement.
   Les bords longitudinaux dudit tube principal sont, de préférence, soudés sur ladite paroi intérieure.
   Ledit tuyau d'acheminement est, de préférence, positionné à l'extrémité supérieure de ladite paroi intérieure de la citerne.
   Le dispositif de lavage selon l'invention comporte, de préférence, un tube de protection constitué d'un tube secondaire coupé longitudinalement, présentant une section supérieure à la section du tuyau d'acheminement et positionné sensiblement autour dudit tuyau d'acheminement.
   Ledit tube de protection présente, de préférence, une section partiellement circulaire, mais il est également possible de réaliser un tuyau d'acheminement à section rectangulaire ou ovale, ... En outre, cette section peut ne pas être constante sur toute la longueur du tuyau d'acheminement.
   La présente invention se rapporte également à un procédé de fabrication d'un dispositif de lavage selon l'invention, remarquable en ce que ledit tuyau d'acheminement et/ou ledit tube de protection est ou sont constitué(s), respectivement d'un tube principal coupé longitudinalement ou d'un tube secondaire coupé longitudinalement, ledit ou lesdits tube(s) étant fabriqué(s) par pliage d'un profilé longitudinal. Said conveying pipe preferably consists of a main tube cut longitudinally and positioned against the inner wall of said tank, said inner wall closing said cut tube.
Said conveying pipe preferably has a partially circular section, but it is also possible to produce a conveying pipe with rectangular or oval section, etc. Furthermore, this section may not be constant over the entire length the routing pipe.
The longitudinal edges of said main tube are preferably welded to said inner wall.
Said conveying pipe is preferably positioned at the upper end of said inner wall of the tank.
The washing device according to the invention preferably comprises a protective tube made up of a secondary tube cut longitudinally, having a cross section greater than the cross section of the conveying pipe and positioned substantially around said conveying pipe.
Said protection tube preferably has a partially circular section, but it is also possible to produce a conveying pipe with a rectangular or oval section, etc. In addition, this section may not be constant over the entire length of the routing pipe.
The present invention also relates to a method of manufacturing a washing device according to the invention, remarkable in that said conveying pipe and / or said protective tube is or are constituted (s), respectively of a main tube cut longitudinally or a secondary tube cut longitudinally, said tube (s) being produced by bending a longitudinal profile.

La présente invention se rapporte également à une citerne, et notamment citerne sensiblement cylindrique de camion, comportant un dispositif de lavage selon l'invention, comportant au moins une bouche d'entrée située à l'extérieur de la citerne, un tuyau d'acheminement et au moins une tête de projection située à l'intérieur de la citerne, ledit tuyau d'acheminement étant situé, au moins partiellement, à l'intérieur de ladite citerne.The present invention also relates to a tank, and in particular a substantially cylindrical tank truck, with a washing device according to the invention, comprising at least one inlet mouth located outside the tank, a pipe routing and at least one projection head located at the interior of the tank, said delivery pipe being located, at least partially, within said tank.

Avantageusement, le dispositif de lavage selon l'invention est bien protégé, tout en étant facile d'accès si des réparations sont nécessaires. En outre, il est simple à monter, directement à l'intérieur de la citerne et est plus résistant que les dispositifs de l'art antérieur.
   Avantageusement également, la déperdition de chaleur par la rampe de lavage est plus faible, du fait qu'une petite partie seulement du dispositif de lavage est à l'extérieur de la citerne.Advantageously, the washing device according to the invention is well protected, while being easy to access if repairs are necessary. In addition, it is simple to mount, directly inside the tank and is more resistant than the devices of the prior art.
Advantageously also, the heat loss through the washing ramp is lower, because only a small part of the washing device is outside the tank.
