Definitions

  • the invention relates to a method for separating two sealed adjoining enclosures communicating with each other by a passage, and a double door which can be used to effect this separation.
  • watertight containment cells or enclosures are used to protect personnel located outside the products handled.
  • Document FR-A-2 070 482 relates to the sealed connection of a removable container to a fixed confinement enclosure. To make this connection, use flanges fitted with seals of particular types, adapted to cooperate in leaktight fashion with one another as well as with complementary seals disturbed by the losses.
  • the cells or adjoining enclosures in which such methods are implemented are generally permanently mounted. However, it may happen for various reasons that it is necessary to dismantle at least some of these cells. This situation can arise in particular when a factory has to be closed or moved to another site.
  • the present invention specifically relates to a method for separating two tightly sealed enclosures without breaking the confinement of these enclosures, and which can be used regardless of the shape and size of the passages connecting the speakers.
  • folding doors are used. Before introducing the double door through the access opening, this double door is then folded along at least one articulation line, then the double door is unfolded after its introduction into the enclosures.
  • the double door is put in place so that each of the inflatable seals is in front of a groove formed in the corresponding enclosure, inside the passage .
  • the invention also relates to a double door usable for the separation of two adjoining waterproof enclosures communicating through a passage and at least one of which has an access opening normally closed by a plug, this double door being characterized in that it comprises two adjoining doors each comprising a rigid frame provided with a peripheral edge likewise forms that said passage and of dimensions smaller than the latter, an inflatable and watertight seal mounted on the peripheral edge of the frame, and a watertight disc whose peripheral edge is tightly fixed on the inflatable seal, the discs of the two doors being fixed to each other at their periphery by waterproof and disconnectable adhesive means under the effect of a given separation force.
  • each of the inflatable seals comprises an inflatable inner air chamber and an outer sealing skin, each of the sealed discs being formed of a flexible membrane whose peripheral edge is tightly fixed on the sealing skin of one of the seals.
  • Each of the rigid frames can in particular be made of stamped sheet metal and then comprises a rim having a U-shaped section and defining the peripheral edge of the frame, and a plate extending the rim and on which the sealed disc is supported.
  • the rigid frame of each of the doors is formed of several sections articulated along at least one line of articulation.
  • each articulation line is oriented in a direction approximately perpendicular to a direction corresponding to a smaller dimension of the peripheral edge of the frame.
  • At least one retractable stiffener articulated on one of the sections of the frame keeps each door unfolded.
  • the frame of one of the doors has on the side opposite the other door at least one positioning member capable of coming to bear on a shoulder formed in the passage.
  • FIG. 1 there are shown two sealed containment or containment cells, generally designated by the references 10a and 10b. These cells 10a and 10b are joined so as to communicate permanently by a passage 12 having a section whose shape may not be circular, as illustrated in FIG. 2.
  • this passage 12 can be large.
  • this passage can have a height of 1.40 m and a width of 1 m.
  • the sealed connection of the two enclosures 10a and 10b can be obtained by means of fixing of any type, generally designated by the reference 14 in FIG. 1.
  • these fixing means 14 can in particular consist of tilting latches articulated on a flange 16a formed on the enclosure 10a around the passage 12. When the enclosures are placed side by side, these latches are folded down behind a flange 16b formed on the enclosure 10b around the passage 12. The sealing of the connection thus produced is obtained for example by means of seals 15 compressed between the flanges 16a and 16b by the fixing means 14.
  • the chambers 10a and 10b can in particular be used to carry out successive operations on irradiated fuel assemblies originating from nuclear reactors, during the dismantling of these assemblies. They are normally fixed to each other permanently.
  • this result is obtained by means of a double door generally designated by the reference 18 and formed by two adjoining doors 20a and 20b.
  • this double door 18 is first introduced into one of the enclosures (for example the enclosure 10b), through an access opening 22 formed in this enclosure.
  • This access opening 22, of conventional design, is normally closed by a plug 24 ensuring when the enclosure 10b is sealed.
  • the double door is placed in a container which is docked by an appropriate mechanism on the flange delimiting the opening 22.
  • the container cover is then secured to the plug 24.
  • the access opening 22 formed in the enclosure 10b is a circular opening whose diameter is less than the smallest dimension of the passage 12 to be closed. Consequently, the double door 18 which must close this passage crosses the opening 22 in a folded position as shown at 18 'in FIG. 1.
  • the door 18 may not be folding.
  • each of the doors 20a and 20b which constitutes it is located respectively inside the flanges 16a and 16b of the enclosures 10a and 10b. This position is shown in solid lines in FIG. 1.
  • each of the doors 20a and 20b forming the double door 18 comprises a rigid metal frame 21a, 21b made of stamped sheet metal.
  • This frame 21a, 21b comprises a rim 22a, 22b having a U-shaped section and a flat flange 23a, 23b extending one of the edges of the rim.
  • the rim 22a, 22b of each of the metal frames delimits the outer peripheral edge of the frame and has a shape identical to the shape of the passage 12 to be closed.
  • the dimensions of this peripheral edge are however slightly less than the dimensions of the passage, in order to allow the installation of the double door 18.
  • Each of the doors 20a and 20b of the double door 18 further comprises an inflatable seal 24a, 24b respectively.
  • each of the inflatable seals comprises an inner air chamber 26a, 26b housed in an outer sealing skin 28a, 28b.
  • Each of the inflatable seals 24a, 24b is mounted on the peripheral edge of the frame 21a, 21b. More specifically, the inflatable seals are mounted in the rim 22a, 22b of each of the frames.
  • each of the seals 24a, 24b is allowed thanks to a valve 30a, 30b passing through the rim 22a, 22b.
  • Each valve 30a, 30b can be connected to a known inflation system, automatic or manual, which is shown diagrammatically at 31a, 31b in FIG. 3.
  • each of them further comprises a sealed disc formed of a flexible membrane 32a, 32b, the outer peripheral edge of which is welded to the sealing skin 28a, 28b of the corresponding door and which is supported on the flange 23a, 23b of this door.
  • the two doors 20a and 20b are arranged so that the flexible membranes 32a and 32b are placed practically in contact with one another. More specifically, the doors 20a and 20b are normally joined to each other before being introduced into the chambers to be separated. This joining is obtained by means of an adhesive and waterproof device 34 extending over the entire periphery of the double door, between the flexible membranes 32a and 32b.
  • This adhesive device 34 can in particular be constituted by one or two double-sided adhesive strips.
  • the adhesive device 34 has the dual function of allowing a disconnectable connection between the doors 20a and 20b and of isolating the space trapped between these doors from the interior atmosphere of the enclosures, when the double door is introduced into them.
  • the two doors 20a and 20b of the double door 18 are secured by means of the adhesive device 34.
  • the inflatable seals 24a and 24b are then deflated.
  • the seals 24a and 24b are inflated using the inflation systems 31a and 31b. This produces the desired seal, whatever the shape given to the interior surface of the passage 12.
  • grooves in a circular arc 35a, 35b are formed on each of the enclosures 10a, 10b inside the passage 12, in order to receive and maintain the inflatable seals 24a and 24b.
  • such grooves are not essential to the invention.
  • the two enclosures can be separated, as well as the two doors 20a and 20b forming the double door. Any suitable means can be used for this purpose, after the fixing means 14 have been unlocked.
  • the separation of the enclosures and the doors is obtained by means of an inflatable seal 36 mounted in an annular groove 38 formed for example in the flange 16a of the enclosure 10a, this groove 38 opening onto the face of the flange 16a in contact with the flange 16b of the enclosure 10b.
  • the inflatable seal 36 is deflated. It remains in this position throughout the use of speakers 10a and 10b.
  • this inflatable seal 36 facilitates the separation of the doors 20a and 20b connected by the adhesive device 34.
  • the pressurization of the joint 36 has the effect of exerting between the flanges 16a and 16b, and therefore between the doors 20a and 20b, a force tending to separate these different parts.
  • the release of the adhesive device 34 connecting the doors 20a and 20b is thus easily obtained.
  • an inflatable seal 36 in one of the flanges by which the speakers are connected is not essential to the invention. Indeed, the separation of the enclosures and the adjoining doors can be obtained by any other means allowing to exert a force of separation between the enclosures, even if these are not originally designed in the manner described with reference to the figure 3.
  • the double door 18 is equipped with certain improvements which are not essential to the invention, which will now be described.
  • the rigid frame of one of the doors (the frame 21b of the door 20b in the figures) further comprises a positioning member constituted by a flange 40 fixed on the rim 22b of this frame 21b, for example by welding.
  • This flange 40 is located on the side opposite to the flange 23b and it extends radially outwards so as to have, at its peripheral edge, a dimension slightly greater than the dimensions of the passage 12, at least at certain points.
  • FIGS. 3 and 4 clearly illustrate, when the double door 18 is placed in the passage 12, the flange 40 automatically comes to bear on a shoulder 42 formed for this purpose in the passage 12.
  • the reinforcements 21a, 21b of each of the doors 20a and 20b are then cut into strips 43 hinged together according to articulation lines 44 approximately parallel to one another.
  • the articulation lines 44 of the two doors 20a, 20b face each other, so that the double door 18 formed by these two adjoining doors can be folded along these lines.
  • the articulation lines 44 extend perpendicular to the direction corresponding to the smallest dimension of the passage 12.
  • the width of the passage 12 being less than its height, the lines d hinge 44 are oriented vertically.
  • the maintenance of the frames 21a, 21b in the unfolded position is obtained by providing on each of them one or more stiffeners 46 pivotally mounted on one of the reinforcement strips 43.
  • the stiffeners 46 can move between a fold-back position of the frame in which these stiffeners are oriented approximately parallel to the articulation lines 44 (dashed lines in FIG. 2) and a position for locking the frame in position. open, in which the stiffeners 46 are oriented approximately perpendicularly to these lines 44 (solid line in FIG. 2).
  • the use of a double door designed in the manner which has just been described makes it possible to separate adjoining enclosures communicating by a passage, whatever the shape and dimensions of this passage.
  • this separation is obtained practically without the atmosphere contained inside the enclosures coming into contact with the outdoor atmosphere.
