Definitions

  • the present invention relates to a mobile device for mixing at least two products from storage pots in drums equipped with internal kneading means which can be driven in rotation by a kneading head, via a coupling disconnectable.
  • the invention advantageously applies to the coating with an organic binder to the epoxy resins of solid particles such as spent ion exchange resins originating from the purification pots of the primary circuits of pressurized water nuclear reactors and storage pools. fuels.
  • the invention is not limited to this application and can be used in all cases where a mixture of the same products must be carried out successively in several drums or containers.
  • the present invention specifically relates to a mobile mixing device in which are carried out both the metering of the products, the transfer of these products into the barrels, their mixing and possibly the sealing of the barrels in a particularly compact installation which comes itself successively dock each of the drums, whose cost and operating personnel are significantly reduced, which presents no risk of leakage and which provides good protection of personnel for a speed of execution comparable to that of multi-station machines more efficient.
  • the size of the installation is five to six times less than that of a conventional multi-user installation and its cost is reduced by a factor of 2 or 3.
  • the fixed base comprises a sole in which the receptacles are formed and a cylindrical shell whose vertical axis coincides with the axis of rotation of the turret in which is received one pots.
  • the turret is then preferably supported by the upper edge of the cylindrical shell and has a rotating cover closing the shell and from which the pot received in the shell is suspended.
  • the mixing head is suspended from a bracket by a flexible link on which act the means for vertically moving the mixing head.
  • the turret may also include means for handling a barrel cover making it possible to replace the kneading head with this cover when the head is released from the corresponding barrel by a rotation of the turret
  • these means for handling the barrel cover comprise for example a second bracket pivotally supported about an offset vertical axis towards the mixing head with respect to the axis of rotation of the turret.
  • the mobile coating installation shown in Figure 1 mainly consists of a fixed base 10 and a mobile turret 12 supported by the base 10 so as to be able to rotate around a vertical axis XX '.
  • the fixed base 10 comprises a sole 10a resting on the ground and having recesses in an arc 14 ( Figure 2) in which can be placed drums 16 intended to receive the coated products.
  • the recesses 14 are arranged so that the axes of the drums 16 placed in these recesses are arranged on the same cylinder of revolution of axis XX '. In the embodiment shown, only two recesses 14 are formed on the sole 10a, but it will easily be understood that the number of these recesses can be greater if it is desired to place more than two barrels simultaneously in the machine.
  • the base 10 further comprises a cylindrical ferrule 10b whose axis coincides with the vertical axis XX 'and which rotatably supports the turret 12 by its upper edge.
  • the mobile turret 12 for its part, comprises a metering pot 18 in which the ion exchange resins to be coated are metered and temporarily stored, two metering pots 20 serving for metering and temporarily storing the resin and the coating hardener, a mixing head 22, as well as flexible pipes 44, 46, 52 connecting each of the metering pots to this coating head and which will be described later in more detail.
  • the movable turret 12 comprises a support cover 24 rotatably mounted by means of a ball bearing in a ring 26 fixed in a removable manner, for example by means of screws on the upper edge of the cylindrical shell 10b.
  • the assembly constituted by the fixed base 10 and by the rotating cover 24 thus form a biological protection enclosure in which is received the metering pot 18 serving for temporarily storing the resin which it is desired to coat.
  • the measuring jug 18 is suspended from the rotating cover 24 by a skirt 28 designed to serve as a retention in the event of a leak.
  • the skirt 28 is equipped with a humidity detector (not shown).
  • the rotating plug 24 serves as a base for a bracket 30 and a gantry 32 to which are suspended, by means of flanges 34, the metering pots 20 used for metering and temporarily storing the resin and the coating hardener.
  • the gantry 30 supports the mixing head 22. More precisely, the end of the gantry 30 is provided with a mad pulley 36 on which a cable 38 passes at the lower end of which the head 22 is hung, the other end of the cable 38 being fixed to the rod of a jack 40 whose body is integral with the bracket 30.
  • the arrangement which has just been described allows, by a rotation of the turret 12 about its vertical axis XX ', to bring the kneading head 22 alternately above each of the drums 16 received in the recesses 14, the setting in use of the jack 40 having the effect of moving the head 22 between a high position allowing the rotation of the turret and a low position in which the mixing head is coupled to the corresponding barrel.
  • the mixing head 22 and the drums 16 are produced in the manner described in French patent application No. 8400 543 filed on January 3, 1984 for a device for coating particles by Mr. Henri LUMPP.
  • the kneading head 22 mainly consists of a geared motor assembly 22a capable of driving in rotation, by means of an electromagnetic coupling 22b, a vertical shaft 16a fitted with blades 16b and placed inside each of the drums 16.
  • the kneading head 22 further comprises a plug 22c closing off the upper face of the barrel and comprising passages into which the pipes connected to the pots 18 and 20 open.
  • the cover 22c completes the biological protection of the barrel, which is also provided by a transport shell 42 in which the barrel is housed.
  • a flow pipe 44 and a return pipe 46 connect the metering pot 18 containing the resin to be coated to the plug of the kneading head 22.
  • Each of the metering jars 20 respectively containing the resin and the coating hardener is connected to the plug of the mixing head 22 by a pipe 52, the transfer of the resin, then of the hardener, being effected by pushing with compressed air .
  • the stirring system constituted by the shaft 16a and by the blades 16b is actuated by the implementation of the motor 22a of the mixing head.
  • the electromagnetic coupling 22b is actuated in order to uncoupler the head 22 from the kneading members 16a internal to the barrel.
  • the head 22 is then raised by using the jack 40.
  • the mixing head 22 can then be brought above another barrel 16 placed in another recess 14 of the base 10 by the rotation of the turret 12 about its vertical axis XX '. This operation can be performed either manually using a pole, or by adding to the device a motorization system not shown.
  • the device according to the invention is equipped for this purpose with a second bracket 56 pivotally supported by the first bracket 30 around a vertical axis offset from the axis XX 'in the direction of the head. mixing 22.
  • this bracket 56 supports the plug 54 by means of a cable 58 which can move the plug between a high position and a low position under the action of a jack (not shown).
  • the axis of articulation of the bracket 56 on the bracket 30 is positioned so that the plug can be put in place on the barrel as soon as the kneading head 22 has cleared the opening of the latter under the effect the rotation of the turret 12.
  • the invention is not limited to a mobile coating device such as that which has just been described with reference to the figures but can be used in all cases where a mixture of the same products must be carried out successively in several barrels, which occurs in particular in the chemical industry. From this point of view, it will be understood that all the characteristics of the device described linked to the dangerous and toxic nature of the products handled (biological protection structure in particular) can be eliminated when the products treated do not have these characteristics.
  • the number of drums that can be docked on the machine can be greater than two without departing from the scope of the invention, just as the number of pots on board the mobile turret can be any number greater than or equal to two.
  • the invention applies regardless of the volume of the products to be mixed, the dimensions of the installation, and in particular of the metering pots and drums, which can be adapted both to the treatment of small quantities and of large quantities.
