Definitions

  • the present invention relates to a tank container comprising a frame supporting a tank comprising a cylindrical side wall and two end walls.
  • Viscous or pasty products cannot be stored or transported in existing tank containers. Indeed, as these products tend to sediment or form a compact mass after a relatively short rest time, their extraction from tank-containers would be very difficult, if not impossible, if their stay in them were to be prolonged.
  • the present invention proposes to overcome these difficulties and, to do this, it relates to a tank container which is characterized in that it comprises a mixer comprising blades whose active edge is adjacent to the internal face of the side wall of the tank, these blades being fixed to the free end of arms mounted radially on a motor shaft located on the longitudinal axis of the tank and mounted for rotation on the end walls thereof.
  • the product in a tank container made in accordance with the invention can now be continuously stirred. It therefore no longer risks sedimenting or solidifying, which allows it to be removed from the tank container at any time, regardless of the length of its stay in it.
  • the mixer shaft can be rotated by a motor provided on the tank container and supplied either from a stationary source when the tank container is placed in a warehouse, either from a source mounted on the vehicle used to transport the tank container.
  • each blade is carried by at least two radial arms fixed on the motor shaft along the same generator.
  • the mixer in this case a particularly simpie structure, which allows the construre and install easily and with a f d ible cost.
  • the blades are divided into groups in each of which they are diametrically opposite.
  • the blades of each group exert a shearing action on the product each time they come into contact and thus subject it to an even more intense stirring.
  • the blades of two adjacent groups are angularly offset, for example by 90 °.
  • the blades are planar and have, near their active edge, a flange bent forward in the direction of rotation of the motor shaft.
  • the blades Thanks to their rim, the blades always carry with them a certain quantity of product which they let fall down when their height above the free surface of the product is sufficient.
  • the product also has the possibility of trickling into the tank, which further improves the efficiency of its mixing.
  • the blades are fixed on the arms which are furthest from the median transverse plane of the tank by means of a thickness gauge.
  • the product located in the zone of action of these is forced to move in the direction of the center of the tank and therefore undergoes additional mixing.
  • the motor shaft of the mixer preferably has a square section in its part located inside the tank, the arms being fixed on it two by two by means of two complementary parts each bearing on two of its adjacent faces.
  • the angular offset of the blades of the different groups of blades can in this case be determined with precision without the slightest trial and error. It suffices to ensure that the complementary parts carrying the arms of two adjacent groups of blades are offset by 90 ° on the motor shaft.
  • the tank may optionally include heating means arranged on the outer face of the lower part of its side wall.
  • the end wall 6 is provided with a drain valve, not shown.
  • the tank 3 is arranged inside the frame to which it is connected. by means of multidirectional elastic pads 9, 10. These pads, which may be of the type described in French patent application No. 80 00056 of January 3, 1980, are interposed, the first between the reinforcement rings of the side wall 4 and the beams 1 of the frame and the second between the reinforcement rings and bracons 11 fixed to the upper part of the vertical uprights 2.
  • the tank 3 contains a mixer comprising blades 12 whose active edge 13 is adjacent to the internal face of the side wall 4. These blades are fixed to the free end of arms 14 mounted radially on a shaft motor 15 of square section, located on the longitudinal axis of the tank and mounted journalling in two bearings 16, 17 carried by reinforcing sleeves 16A, 16B fixed in circular openings made in the end walls 5 and 6.
  • the blades 12 are each carried by two radial arms 14 fixed on the same generator of the motor shaft 15. They are distributed in three groups in each of which they are diametrically opposite, the blades of two adjacent groups being furthermore angularly offset by 90 °.
  • the blades are flat and have, near their active edge 13, a flange 18 which is bent forward in the direction of rotation R of the shaft 15.
  • FIG. 1 also shows, the blades of the two end groups are fixed to the arms 14 which are closest to the end walls 5, 6 by means of a shim of thickness 19, which allows them to be tilt on the longitudinal axis of the tank.
  • the arms 14 supporting the blades of the same group are mounted two par. Two on the motor shaft 15 by means of two complementary parts 20 connected to the to each other by conventional fixing means such as bolts, these parts each bearing on two adjacent faces of the shaft 15 which they enclose between them.
  • the tank 3 has electric heating means arranged on the external face of the part. lower side wall 4, these heating means may for example be constituted by heating cables 21 of the Pyrotenac type embedded inside an insulating sheath 22.
  • a cabinet, not shown, can advantageously be mounted on the framework of the tank container to control and regulate heating.
  • the shaft 15 is rotated by means of an electric motor 23, the output shaft of which is connected to a reduction gear 24, which is engaged with the end of the shaft 15 which is located on the side of the terminal wall 5 of the tank.
  • the reduction gear 24 is fixed on a support 25 which is itself fixed on the bearing 16. It will also be noted that at its end situated on the side of the end wall 5 dala tank, the shaft 15 is provided with an extension 26 connecting it to the output shaft 27 of the reduction gear 24, this extension having a square section head 28 threaded into the shaft 15 and two cylindrical parts 29 and 30 s' pressing on the bearing 16, one by means of a lip seal 31 and a scraper seal 32 and the other by means of a bearing 33.
  • the shaft 15 is provided with another extension 26 which rests on the bearing 17 also by by means of two seals 31 and 32 and of a bearing 33 and which is isolated from the outside by means of a plug 34 fixed on the bearing 17.
  • the tank container which has just been described has been designed for the transport of pasty products such as cocoa mass. It goes without saying, however, that it could also be used to transport liquid products requiring continuous stirring and / or heating during their stay in the tank.
