  • the conveying pipe (4) is positioned outside the body of the tank (2), that is to say above the outer wall (23) of the tank.
  • the major disadvantage of this first variant is that the conveying pipe is not protected from the external elements.
  • the delivery pipe may be damaged by stone splashes or improper maneuvering by the truck driver.
  • the pipe is not protected from heat loss.
  • the conveying pipe (4) is positioned inside the wall of the body of the tank (2) 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 disadvantage of this second variant is that if sealing problems arise in the washing device, particularly at the connection between the conveying pipe (4) and the downcomers (7), the fluid s escapes inside the insulation layer (20) and can degrade it. In addition, repairs to such problems generate significant costs of dismantling the structure of the tank.
  • the present invention seeks to overcome the disadvantages of the prior art by proposing that the conveying pipe is both protected from the external elements, well insulated and easier to access.
  • the present invention is of the type described above and is remarkable, in its broadest sense, in that the conveying pipe is located, at least partially, inside said tank and in said conveying pipe consists of a main pipe 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 rectangular or oval section conveying pipe, ... In addition, this section may not be constant over the entire length of the 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 consisting of a secondary tube cut longitudinally, having a section greater than the section of the conveying pipe and positioned substantially around said conveying pipe.
  • Said protective tube preferably has a partially circular section, but it is also possible to produce a rectangular or oval section conveying pipe, ... In addition, this section may not be constant over the entire length of the pipe. 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 consist (s), respectively of a main tube cut longitudinally or a secondary tube cut longitudinally, said tube (s) being manufactured (s) by folding a longitudinal section.
  • the present invention also relates to a tank, and in particular a substantially cylindrical truck tanker, comprising a washing device according to the invention, comprising at least one inlet mouth located outside the tank, a conveying pipe. and at least one projection head located inside the tank, said delivery pipe being located, at least partially, inside said tank and consisting of a main tube cut longitudinally and positioned against the wall interior of said tank, said inner wall enclosing said cut tube.
  • the washing device according to the invention is well protected, while being easy to access if repairs are necessary.
  • it is simple to mount, directly inside the tank and is stronger than the devices of the prior art.
  • the heat loss through the washing ramp is lower, because only a small part of the washing device is outside the tank.
  • the washing device (1) for washing the inside of a tank (2) according to the invention, illustrated Figures 3 to 7 is of the type having at least one inlet mouth (3) located outside the tank (2), for the suction of a washing liquid, a conveying pipe (4) running along the tank, for conveying the washing liquid and at least one, and preferably several, head (s) of projection (5, 5 ', 5'') located (s) inside the tank (2 ), through which the washing liquid flows.
  • a riser pipe (6) is further provided between the inlet port (3) and the conveying pipe (4) and downcomers (7) are provided between the conveying pipe (4) and each head (5, 5 ', 5 ").
  • the lower end of the projection head (5) is located about 50 centimeters below the inner wall (21), while the lower end of the projection head (5 ') is located at about 10 centimeters. below the inner wall (21).
  • the distance along the axis (22) between two projection head (5) is of the order of 2.4 meters, while the distance along the axis (22) between two projection heads (5 ') or between a projection head (5 ') and a projection head (5 or 5 ") is of the order of 0.8 meters.
  • the rear end of the conveying pipe (4) can also be provided with a projection head (5 ''), as visible figures 4 , oriented not vertically like the projection heads (5, 5 '), but at 45 ° to the vertical.
  • the projection heads (5, 5 ', 5 ") can be provided with pierced balls, rotating balls, ..., to distribute the projection of the cleaning liquid inside the tank, against the inner wall.
  • the tank (2) comprises, a filling system of the tank, and in the bottom of its rear wall (25), an outlet mouth (26) for emptying the tank by gravitation or suction, visible figure 7 .
  • the tank (2) has a length, overall, of the order of 10 meters and an outside diameter of the order of 2 meters.
  • the tank (2) has a capacity of about 29,000 liters.
