L'invention concerne une chaîne blindée d'analyse, de conception modulaire, permettant d'effectuer successivement un certain nombre d'analyses sur des produits tels que des produits radioactifs nécessitant une protection biologique.The invention relates to an armored analysis chain, of modular design, making it possible to successively carry out a certain number of analyzes on products such as radioactive products requiring biological protection.

Dans la pratique, une chaîne blindée d'analyse comprend une série de boîtes d'analyse étanches communiquant entre elles par des passages et entourées, de même que ces derniers, par une protection biologique. Des moyens de manutention à distance tels que des pinces ou des télémanipulateurs permettent aux opérateurs situés à l'extérieur de la protection biologique d'effectuer différentes analyses à l'intérieur de chacune des boîtes ainsi que les manipulations des produits dans les boîtes et entre celles-ci.In practice, an armored analysis chain comprises a series of sealed analysis boxes communicating with one another through passages and surrounded, as well as these, by biological protection. Remote handling means such as tweezers or remote manipulators allow operators located outside the biological protection to perform different analyzes inside each box as well as the handling of products in and between boxes -this.

Habituellement, chaque chaîne blindée d'analyse est réalisée de façon personnalisée, c'est-à-dire qu'elle est conçue pour une utilisation bien déterminée et figée une fois pour toutes. Cela conduit, d'une part, à un prix de revient très élevé de chaque chaîne blindée et, d'autre part, à rendre très difficile l'évolution technique des chaînes réalisées. A titre d'exemple, la fourniture d'une chaîne blindée d'analyse personnalisée représente environ 10.000 heures d'étude.Usually, each armored chain of analysis is carried out in a personalized way, that is to say that it is designed for a well-defined use and frozen once and for all. This leads, on the one hand, to a very high cost price for each armored chain and, on the other hand, to make the technical development of the chains produced very difficult. For example, the supply of an armored personalized analysis chain represents approximately 10,000 hours of study.

L'invention a précisément pour objet une chaîne blindée d'analyse dont la structure modulaire permet de réduire de façon considérable le coût de sa fabrication, l'étude d'une nouvelle chaîne pouvant par exemple être ramenée à environ 1.500 heures, le caractère modulaire de la chaîne permettant en outre de modifier celle-ci et d'en assurer la maintenance de façon particulièrement simple, rapide et peu coûteuse.The subject of the invention is precisely an armored analysis chain, the modular structure of which makes it possible to considerably reduce the cost of its manufacture, the study of a new chain being able, for example, to be reduced to approximately 1,500 hours, the modular nature of the chain also making it possible to modify the latter and to ensure its maintenance in a particularly simple, rapid and inexpensive manner.

Conformément à l'invention, ce résultat est obtenu au moyen d'une chaîne blindée d'analyse comprenant une série de boîtes d'analyse étanches communiquant entre elles par des passages, une protection biologique entourant lesdites boîtes et lesdits passages, des composants d'analyse placés dans chacune des boîtes d'analyse, des moyens de préhension pour effectuer des manipulations à l'intérieur de chacune des boîtes, depuis l'extérieur de la protection biologique, et des moyens pour introduire des produits dans l'une au moins des boîtes d'analyse et pour en extraire ces produits, caractérisée par le fait que les boîtes d'analyse sont standardisées selon au plus deux modèles différents, dont un premier est pourvu d'une partie desdits moyens pour introduire et extraire les produits, chacune des boîtes standardisées comprenant plusieurs orifices d'accès identiques, les composants d'analyse étant standardisés et fixés de façon étanche et démontable dans les orifices d'accès, de telle sorte qu'une partie active de chaque composant soit placée dans la boîte étanche et qu'une partie de commande de ce composant soit placée hors de la boîte, à l'intérieur de la protection biologique, cette dernière comportant des bouchons démontables permettant le montage et le démontage d'au moins la partie de commande de chaque composant.According to the invention, this result is obtained by means of an armored analysis chain comprising a series of sealed analysis boxes communicating with each other by passages, biological protection surrounding said boxes and said passages, components of analysis placed in each of the analysis boxes, gripping means for carrying out manipulations inside each box, from outside the biological protection, and means for introducing products into at least one of the analysis boxes and for extracting these products, characterized in that the analysis boxes are standardized according to at most two different models, one of which is provided with part of said means for introducing and extracting the products, each of standardized boxes comprising several identical access orifices, the analysis components being standardized and fixed in a sealed and removable manner in gold ifices of access, so that an active part of each component is placed in the sealed box and a control part of this component is placed outside the box, inside the biological protection, the latter comprising removable plugs allowing the assembly and disassembly of at least the control part of each component.

De façon plus précise, chaque boîte standardisée comprend une face avant, une face arrière et deux faces latérales.More precisely, each standardized box includes a front face, a rear face and two side faces.

La face avant de chaque boîte standardisée est traversée par les moyens de préhension, constitués par exemple par des pinces ou des télémanipulateurs, et elle comporte avantageusement au moins une paroi transparente standardisée et fixée de façon étanche et interchangeable sur la boîte, en face d'un hublot formé dans la protection biologique.The front face of each standardized box is traversed by the gripping means, constituted for example by pliers or telemanipulators, and it advantageously comprises at least one standardized transparent wall and fixed in a sealed and interchangeable manner on the box, opposite a window formed in biological protection.

La face arrière de chaque boîte standardisée comprend quant à elle au moins une partie horizontale sur laquelle sont soudés les orifices d'accès servant à recevoir les composants d'analyse. Lorsque la boîte appartient au modèle pourvu d'une partie des moyens pour introduire et extraire les produits, la face arrière de cette boîte comporte également, en dessous de la paroi sensiblement horizontale, au moins une ouverture d'accès normalement obturée par une porte.The rear face of each standardized box comprises at least one horizontal part on which are welded the access orifices used to receive the analysis components. When the box belongs to the model provided with a part of the means for introducing and extracting the products, the rear face of this box also comprises, below the substantially horizontal wall, at least one access opening normally closed by a door.

En outre, chacune des deux faces latérales de chaque boîte standardisée comporte un orifice de liaison. Les orifices situés en bout de chaîne ainsi que certains autres peuvent être fermés par des portes d'obturation standardisées.In addition, each of the two side faces of each standardized box has a connection orifice. The holes at the end of the chain as well as some others can be closed by standardized shutter doors.

Les orifices de liaison de deux boîtes voisines sont reliés par les passages précités, qui sont formés dans des cloisons intermédiaires standardisées, liées de façon démontable à la protection biologique.The connection orifices of two neighboring boxes are connected by the aforementioned passages, which are formed in standardized intermediate partitions, detachably linked to biological protection.

Ces cloisons intermédiaires standardisées sont choisies parmi trois modèles différents comprenant :

  • une cloison pleine, dépourvue de porte ;
  • une cloison de protection biologique, équipée d'une porte, de moyens de commande de cette porte, de moyens de liaison étanche entre le passage formé dans la cloison et les orifices de liaison des boîtes voisines, et d'une tablette de transfert mobile entre ces boîtes ;
  • une cloison pleine, dépourvue de porte et équipée de moyens de liaison étanche entre le passage formé dans la cloison et les orifices de liaison des boîtes voisines, et d'une tablette de transfert mobile entre ces boîtes.
These standardized intermediate partitions are chosen from three different models including:
  • a solid partition, without door;
  • a biological protection partition, equipped with a door, means for controlling this door, sealing means between the passage formed in the partition and the connection orifices of neighboring boxes, and a mobile transfer shelf between these boxes;
  • a solid partition, devoid of a door and equipped with sealed connection means between the passage formed in the partition and the connection orifices of the neighboring boxes, and of a mobile transfer shelf between these boxes.

De préférence, la protection biologique est également formée d'éléments standardisés, avantageusement réalisés en fonte, comprenant, pour chacune des boîtes un mur avant standardisé muni d'au moins un hublot et que traversent les moyens de préhension, une dalle inférieure standardisée, munie de moyens de positionnement de la boîte, un mur inférieur arrière standardisé, des éléments supérieurs démontables et standardisés du mur arrière, et un toit standardisé muni desdits bouchons démontables ; les éléments standardisés de la protection biologique comprenant de plus des murs d'extrémité droite et gauche standardisés.Preferably, the biological protection is also formed of standardized elements, advantageously made of cast iron, comprising, for each of the boxes a standardized front wall provided with at least one porthole and through which the gripping means pass, a standardized lower slab, provided with means for positioning the box, a standardized rear wall, removable and standardized upper elements of the rear wall, and a standardized roof provided with said removable plugs; the standardized elements of biological protection further comprising standardized right and left end walls.

Dans le cas où les boîtes d'analyse comprennent une partie des moyens pour introduire et extraire les produits, le mur inférieur arrière standardisé de la protection biologique comprend une ouverture équipée d'une porte d'accès à masselottes.In the case where the analysis boxes comprise part of the means for introducing and extracting the products, the standardized lower rear wall of the biological protection comprises an opening equipped with an access door for weights.

Avantageusement, la standardisation de la chaîne blindée d'analyse concerne également des châssis sur lesquels repose la protection biologique associée à chacune des boîtes standardisées, des pupitres inférieur et supérieur de commande par lesquels arrivent notamment les différents fluides servant à asservir les composants d'analyse et à effectuer les analyses proprement dites, ainsi que des éléments reliant un siphon formé dans le fond de chacune des boîtes à un caniveau égout prévu dans le sol.Advantageously, the standardization of the armored analysis chain also relates to frames on which the biological protection associated with each of the standardized boxes rests, lower and upper control consoles through which the various fluids used to control the analysis components arrive. and to carry out the analyzes proper, as well as elements connecting a siphon formed in the bottom of each of the boxes to a drain channel provided in the ground.

Enfin, chacun des composants d'analyse comporte avantageusement une bride standard équipée de moyens d'orientation, de centrage et de fixation étanche de cette bride sur l'un des orifices d'accès. En outre, des brides pleines standardisées formant obturateur sont prévues pour être fixées de façon étanche dans les orifices d'accès qui restent inoccupés.Finally, each of the analysis components advantageously comprises a standard flange equipped with means of orientation, centering and tight fixing of this flange on one of the access orifices. In addition, standardized full flanges forming a shutter are provided to be fixed in leaktight manner in the access openings which remain unoccupied.

La chaîne blindée d'analyse illustrée sur la figure 1 comprend, de façon habituelle, un certain nombre de boîtes d'analyse étanches 10, reliées les unes aux autres par des passages 12, l'ensemble étant placé à l'intérieur d'une protection biologique 14. Deux boîtes étanches 10 seulement ont été représentées sur la figure 1, pour faciliter la compréhension, mais on comprendra aisément que le nombre de boîtes utilisées dans une chaîne blindée d'analyse déterminée peut être quelconque et très supérieur à deux.The armored analysis chain illustrated in FIG. 1 usually comprises a certain number of sealed analysis boxes 10, connected to each other by passages 12, the assembly being placed inside a biological protection 14. Only two watertight boxes 10 have been shown in FIG. 1, to facilitate understanding, but it will easily be understood that the number of boxes used in a determined armored analysis chain can be any and much more than two.

Chacune des boîtes d'analyse étanches 10 correspond à un poste de travail dans lequel des opérateurs peuvent effectuer sur un ou plusieurs produits les analyses successives désirées, grâce à des composants d'analyse appropriés, montés dans chacune des boîte.Each of the sealed analysis boxes 10 corresponds to a work station in which operators can carry out on one or more products the desired successive analyzes, using appropriate analysis components, mounted in each of the boxes.

La manipulation des produits est réalisée dans l'exemple représenté grâce à deux télémanipulateurs 16 pour chacune des boîtes 10, mais on comprendra aisément que ces télémanipulateurs peuvent être remplacés par tout autre moyen de préhension tel que des pinces.The handling of the products is carried out in the example shown using two remote manipulators 16 for each of the boxes 10, but it will easily be understood that these remote manipulators can be replaced by any other gripping means such as pliers.

Pour permettre aux opérateurs d'effectuer les analyses dans de bonnes conditions, chacune des boîtes 10, est équipée d'une paroi transparente 18 qui est placée en face d'un hublot 20 traversant le mur avant de la protection biologique 14, du même côté que les télémanipulateurs 16. Un éclairage 22 (figure 2) est également placé à l'intérieur de chacune des boîtes 10, afin d'améliorer les conditions de manipulation des produits.To allow operators to carry out the analyzes in good conditions, each of the boxes 10 is equipped with a transparent wall 18 which is placed opposite a porthole 20 crossing the front wall of the biological protection 14, on the same side as the remote manipulators 16. An illumination 22 (FIG. 2) is also placed inside each of the boxes 10, in order to improve the conditions for handling the products.

Conformément à l'invention, on donne à la chaîne blindée d'analyse une structure modulaire sur la base de laquelle des chaînes adaptées aux différents besoins peuvent être conçues et réalisées de façon particulièrement simple, rapide et peu onéreuse. De plus, cette conception modulaire permet d'intervenir sur une chaîne, soit pour en effectuer la maintenance, soit pour y apporter certaines modifications (par exemple, dépose d'une boîte hors service et mise en place d'une nouvelle boîte de même type, sans arrêter la bonne marche du reste de la chaîne), d'une manière également simple et peu coûteuse.According to the invention, the armored analysis chain is given a modular structure on the basis of which chains adapted to different needs can be designed and produced in a particularly simple, rapid and inexpensive manner. In addition, this modular design makes it possible to intervene on a chain, either to carry out maintenance or to make certain modifications (for example, removal of an out of service box and installation of a new box of the same type , without stopping the the rest of the chain), in an equally simple and inexpensive manner.

Ainsi, chacune des boîtes d'analyse 10 est standardisée et peut être choisie parmi deux modèles différents, selon qu'il est nécessaire ou non de pouvoir y introduire ou en extraire des produits.Thus, each of the analysis boxes 10 is standardized and can be chosen from two different models, depending on whether or not it is necessary to be able to introduce or extract products therefrom.

Les boîtes d'analyse étanche 10 des deux modèles ont des dimensions et des formes totalement identiques. Elles comprennent une face avant plane 10a, légèrement inclinée vers le haut, une face arrière 10b comprenant une partie inférieure plane et verticale et une partie supérieure en gradins formant deux parois sensiblement horizontale 10c et 10′c situées à deux niveaux différents, comme l'illustre notamment la figure 3.The sealed analysis boxes 10 of the two models have completely identical dimensions and shapes. They comprise a flat front face 10a, slightly inclined upwards, a rear face 10b comprising a flat and vertical lower part and an upper stepped part forming two substantially horizontal walls 10c and 10′c situated at two different levels, like the illustrates in particular Figure 3.

Chacune des boîtes d'analyse étanches 10 comprend de plus un fond 10d sensiblement plan et horizontal et un plafond 10e sensiblement plan et horizontal. Enfin, on voit notamment sur les figures 1 et 5 que les boîtes 10 comprennent de plus deux faces latérales 10f sensiblement planes et verticales.Each of the sealed analysis boxes 10 further comprises a substantially planar and horizontal bottom 10d and a substantially planar and horizontal ceiling 10e. Finally, it can be seen in particular in FIGS. 1 and 5 that the boxes 10 also comprise two side faces 10f which are substantially planar and vertical.

Sur chacun des deux modèles des boîtes standardisées, la face avant 10a est identique et comporte deux supports 24 de bague d'enceinte (figure 1), pour la traversée des télémanipulateurs 16. De plus, la face avant 10a supporte la paroi transparente 18, qui est standardisée. La paroi transparente 18 est fixée de façon étanche et démontable sur la face avant 10a, par des moyens de fixation tels que des écrous accessibles par le mur avant de la protection biologique 14, après enlèvement de bouchons démontables 25 (figure 3) logés dans ce mur avant. Le remplacement de la paroi transparente 18 s'effectue quant à lui par un trou formé dans le toit de la protection biologique 14 et normalement obturé par un bouchon 26, après retrait des télémanipulateurs 16 et de leurs supports 24 solidaires de la boîte 10.On each of the two models of standardized boxes, the front face 10a is identical and includes two supports 24 for the enclosure ring (FIG. 1), for crossing the remote manipulators 16. In addition, the front face 10a supports the transparent wall 18, which is standardized. The transparent wall 18 is fixed in a sealed and removable manner on the front face 10a, by fixing means such as nuts accessible by the front wall of the biological protection 14, after removal of removable plugs 25 (FIG. 3) housed in this front wall. The replacement of the transparent wall 18 is effected by a hole formed in the roof of the biological protection 14 and normally closed by a plug 26, after removal of the remote manipulators 16 and their supports 24 integral from box 10.

La forme en gradins donnée à la partie supérieure de la paroi arrière 10b de chacune des boîtes standardisées 10 permet de ménager un espace entre la protection biologique 14 et les parois sensiblement horizontales 10c et 10′c, qui sont situées au-dessus du volume intérieur à la boîte 10 correspondante. Grâce à cet agencement, des composants d'analyse standardisés tels que celui 28 qui est illustré schématiquement sur les figures 2 et 3 peuvent être fixés à volonté, de façon étanche et démontable, dans des orifices d'accès identiques 30 formés dans les parois 10c et 10′c. Ces orifices d'accès 30, qui sont de forme circulaire, sont répartis régulièrement sur toute la longueur des parois 10c et 10′c, chacune de ces parois comportant six orifices 30 alignés dans l'exemple décrit.The stepped shape given to the upper part of the rear wall 10b of each of the standardized boxes 10 makes it possible to provide a space between the biological protection 14 and the substantially horizontal walls 10c and 10′c, which are located above the interior volume. to the corresponding box 10. Thanks to this arrangement, standardized analysis components such as that 28 which is illustrated diagrammatically in FIGS. 2 and 3 can be fixed at will, in leaktight and removable manner, in identical access orifices 30 formed in the walls 10c. and 10′c. These access orifices 30, which are circular in shape, are distributed regularly over the entire length of the walls 10c and 10′c, each of these walls comprising six orifices 30 aligned in the example described.

De façon plus précise, les orifices 30 sont formés dans des douilles 32 qui font saillie vers le haut à partir de chacune des parois 10c et 10′c. Chacun des composants d'analyse 28 comporte une partie active 28a, qui est introduite à l'intérieur de la boîte 10 au travers de l'orifice d'accès 30, et une partie de commande 28b qui reste à l'extérieur de la boîte 10, dans l'espace formé entre cette dernière et la protection biologique 14. Une bride 28c séparant les parties 28a et 28b de chaque composant vient reposer de façon étanche sur la douille 30 lorsque la partie active 28a est introduite dans la boîte 10. Chaque composant 28 est en outre équipé d'un cylindre de centrage venant se positionner dans la douille 32, d'un pion d'orientation associé à la bride 28c et coopérant avec une encoche formée dans la douille 32 et de vis imperdables assurant la fixation du composant sur la douille.More specifically, the orifices 30 are formed in sockets 32 which project upwards from each of the walls 10c and 10′c. Each of the analysis components 28 comprises an active part 28a, which is introduced inside the box 10 through the access port 30, and a control part 28b which remains outside the box. 10, in the space formed between the latter and the biological protection 14. A flange 28c separating the parts 28a and 28b of each component comes to rest in a sealed manner on the socket 30 when the active part 28a is introduced into the box 10. Each component 28 is also equipped with a centering cylinder positioned in the socket 32, an orientation pin associated with the flange 28c and cooperating with a notch formed in the socket 32 and captive screws ensuring the fixing of the component on the socket.

Le caractère standardisé des composants d'analyse 28 permet d'équiper chacune des boîtes d'analyse 10 des composants nécessaires à la réalisation des analyses que l'on désire effectuer dans cette boîte. l'implantation des composants 28 sur l'une ou l'autre des parois sensiblement horizontales 10c et 10′c peut, selon le cas, être indifférente ou au contraire imposée par l'encombrement plus ou moins important de la partie active 28a et de la partie de commande 28b de ce composant.The standardized nature of the analysis components 28 makes it possible to equip each of the analysis boxes 10 with the components necessary for carrying out the analyzes you want to perform in this box. the implantation of the components 28 on one or the other of the substantially horizontal walls 10c and 10′c can, as the case may be, be indifferent or on the contrary imposed by the more or less significant bulk of the active part 28a and of the control part 28b of this component.

Afin que l'étanchéité de chacune des boîtes d'analyse 10 soit préservée même lorsque le nombre de composants d'analyse 28 associés à cette boîte est inférieur au nombre d'orifices d'accès 30 de la boîte, les orifices restants sont obturés par des brides pleines standardisées 34, formant des obturateurs qui sont fixés de façon étanche sur les douilles 32, par des moyens analogues aux moyens de fixation des composants 28 décrits précédemment.So that the tightness of each of the analysis boxes 10 is preserved even when the number of analysis components 28 associated with this box is less than the number of access orifices 30 in the box, the remaining orifices are closed by standardized solid flanges 34, forming shutters which are fixed in leaktight manner on the sockets 32, by means similar to the means for fixing the components 28 described above.

Le caractère standardisé des composants d'analyse 28 permet donc à la fois de faciliter la réalisation de toute nouvelle chaîne blindée d'analyse et de modifier une chaîne blindée d'analyse existante, en remplaçant un ou plusieurs des composants d'analyse 28 par d'autres composants ou par des composants identiques lorsque l'un d'entre eux est défaillant. Ces possibilités autorisent une évolution technologique, avec l'étude et la mise en place de nouveaux composants correspondant à de nouveaux besoins des exploitants, ce qui est difficilement envisageable dans l'ancienne conception des cellules.The standardized nature of the analysis components 28 therefore makes it possible both to facilitate the creation of any new armored analysis chain and to modify an existing armored analysis chain, by replacing one or more of the analysis components 28 with d 'other components or by identical components when one of them fails. These possibilities allow a technological evolution, with the study and the installation of new components corresponding to new needs of the operators, which is difficult to envisage in the old design of the cells.

Pour permettre le remplacement des composants d'analyse standardisés 28 et la mise en place et l'enlèvement des brides pleines standardisées 34, la protection biologique 14 entourant la chaîne blindée est équipée, dans la partie du toit surplombant les orifices d'accès 30 de chacune des boîtes 10 de plusieurs bouchons 36 démontables standardisés, et dans le mur arrière, d'éléments supérieurs 38 démontables et standardisés.To allow the replacement of standardized analysis components 28 and the installation and removal of standardized solid flanges 34, the biological protection 14 surrounding the armored chain is equipped, in the part of the roof overhanging the access orifices 30 with each of the boxes 10 of several removable standard stoppers 36, and in the rear wall, of removable and standardized upper elements 38.

Lors du remplacement d'un composant d'analyse standardisé 28, le confinement de la boîte d'analyse 10 correspondante est préservé en plaçant, autour de la douille 32, une manche de vinyle dont les extrémités sont placées, respectivement, dans une gorge ménagée sur la bride 28c du composant et dans une gorge ménagée sur la douille 32. La longueur de la manche de vinyle est choisie en fonction de la longueur de la partie active 28a du composant.When replacing a standardized analysis component 28, the confinement of the corresponding analysis box 10 is preserved by placing, around the sleeve 32, a vinyl sleeve, the ends of which are placed, respectively, in a groove provided on the flange 28c of the component and in a groove formed on the sleeve 32. The length of the vinyl sleeve is chosen as a function of the length of the active part 28a of the component.

Par ailleurs, chacune des faces latérales 10f des modules d'analyse 10 comporte un orifice de liaison circulaire 40, délimité par une bride 42, comme l'illustrent notamment les figures 2 et 3. Les orifices de liaison 40 formés sur les deux faces latérales 10f opposées des boîtes 10 sont disposés coaxialement, de telle sorte que ces orifices 40 sont naturellement alignés lorsque les boîtes 10 sont assemblées pour former une chaîne blindée d'analyse conforme à l'invention.Furthermore, each of the lateral faces 10f of the analysis modules 10 comprises a circular connection orifice 40, delimited by a flange 42, as illustrated in particular in FIGS. 2 and 3. The connection orifices 40 formed on the two lateral faces 10f opposite boxes 10 are arranged coaxially, so that these orifices 40 are naturally aligned when the boxes 10 are assembled to form an armored analysis chain according to the invention.

Chacune des boîtes d'analyse 10 est équipée de plus d'un certain nombre d'aménagements, qui sont totalement identiques d'une boîte à l'autre, pour chacun des deux modèles précités.Each of the analysis boxes 10 is equipped with more than a certain number of arrangements, which are completely identical from one box to another, for each of the two aforementioned models.

Ces aménagements comprennent un siphon 43 d'évacuation des liquides usagés, soudé dans le fond 10b de la boîte 10, approximativement en son centre (figures 2 et 3). Ces aménagements comprennent également différentes tuyauteries.These arrangements include a siphon 43 for discharging used liquids, welded into the bottom 10b of the box 10, approximately at its center (FIGS. 2 and 3). These arrangements also include various pipes.

Dans l'exemple de réalisation illustré sur les figures 2 et 3, ces tuyauteries se composent de deux séries de trois tuyauteries 44 d'arrivée de réactifs qui sont soudées sur la face avant 10a de la boîte 10 au voisinage du toit 10e et à proximité de chacune des faces latérales 10f. Ces tuyauteries comprennent également un ensemble de tuyauteries (non représentées), soudées aux parois de la boîte et permettant, après raccordement, de procéder aux opérations de lavage et de décontamination à l'intérieur de la boîte.In the exemplary embodiment illustrated in FIGS. 2 and 3, these pipes consist of two series of three pipes 44 for the arrival of reactants which are welded to the front face 10a of the box 10 in the vicinity of the roof 10th and in the vicinity of each of the side faces 10f. These pipes include also a set of pipes (not shown), welded to the walls of the box and allowing, after connection, to carry out washing and decontamination operations inside the box.

Les aménagements annexes de chacune des boîtes 10 comprennent également la paroi transparente 18 décrite précédemment et les modules d'éclairage 22. En ce qui concerne ces derniers, chacune des boîtes 10 contient deux modules d'éclairage 22 qui sont disposés contre la face avant 10a de la boîte, de part et d'autre de la paroi transparente 18. Chaque module 22 comprend une enveloppe de verre raccordée de façon étanche sur le toit 10e et dans laquelle est introduit de façon interchangeable un ensemble d'éclairage, de telle sorte que ce dernier est démontable sans rompre l'étanchéité de la boîte. Le remplacement d'un ensemble d'éclairage peut ainsi être effectué par le toit de la protection biologique 14. En outre, les enveloppes de verre des modules d'éclairage 22 peuvent également être remplacées. L'étanchéité de la boîte d'analyse 10 est alors préservée en plaçant un sac de vinyle autour de l'enveloppe de verre, de la même manière que lors du remplacement de l'un des composants d'analyse 28.The additional arrangements of each of the boxes 10 also include the transparent wall 18 described above and the lighting modules 22. With regard to the latter, each of the boxes 10 contains two lighting modules 22 which are arranged against the front face 10a of the box, on either side of the transparent wall 18. Each module 22 comprises a glass envelope tightly connected to the roof 10e and into which is inserted interchangeably a lighting assembly, so that the latter is removable without breaking the seal of the box. The replacement of a lighting assembly can thus be carried out by the roof of the biological protection 14. In addition, the glass envelopes of the lighting modules 22 can also be replaced. The tightness of the analysis box 10 is then preserved by placing a vinyl bag around the glass envelope, in the same way as when replacing one of the analysis components 28.

La seule différence existant entre les deux modèles de boîtes d'analyse standardisées 10 concerne la partie inférieure verticale de la face arrière 10b de ces boîtes. En effet, sur les boîtes pourvues de moyens pour introduire et extraire les produits, cette partie de la face arrière 10b comporte une ouverture d'accès circulaire 45 (figure 2), délimitée par une bride et normalement obturée par une porte standardisée 46. Cette ouverture 45 est placée en face d'une ouverture circulaire 48 formée dans le mur arrière de la protection biologique 14, cette ouverture 48 étant normalement obturée par une porte à masselottes 50.The only difference between the two models of standardized analysis boxes 10 concerns the vertical lower part of the rear face 10b of these boxes. Indeed, on the boxes provided with means for introducing and extracting the products, this part of the rear face 10b has a circular access opening 45 (FIG. 2), delimited by a flange and normally closed by a standardized door 46. This opening 45 is placed opposite a circular opening 48 formed in the rear wall of the biological protection 14, this opening 48 being normally closed by a flyweight door 50.

Comme on l'a illustré de façon très schématique sur la figure 2, cet agencement permet d'introduire et d'extraire des produits sans rompre l'étanchéité de la boîte 10 correspondante, au moyen d'un conteneur de transport 52, de type connu, équipé intérieurement d'un récipient mobile (non représenté) apte à venir s'accoupler directement sur la bride délimitant l'ouverture d'accès 45, lorsque le conteneur 52 a été fixé sur la protection biologique 14 et que la porte à masselottes 50 a été ouverte. De façon bien connue des opérateurs, le conteneur de transport 52 est monté au cours de cette opération sur un chariot 54.As illustrated very diagrammatically in FIG. 2, this arrangement makes it possible to introduce and extract products without breaking the seal of the corresponding box 10, by means of a transport container 52, of the type known, internally equipped with a mobile container (not shown) capable of coming to be coupled directly on the flange delimiting the access opening 45, when the container 52 has been fixed on the biological protection 14 and the flyweight door 50 has been opened. In a manner well known to operators, the transport container 52 is mounted during this operation on a carriage 54.

Chacune des boîtes d'analyse 10 du modèle équipé de l'ouverture d'accès 45 comporte également dans la partie basse de sa face arrière 10b un orifice de raccordement complémentaire (non représenté) obturé par un bouchon standardisé (non représenté).Each of the analysis boxes 10 of the model equipped with the access opening 45 also comprises, in the lower part of its rear face 10b, a complementary connection orifice (not shown) closed by a standardized plug (not shown).

Les boîtes d'analyse 10 qui sont dépourvues de moyens pour introduire et extraire les produits se distinguent des précédentes par le fait que la partie inférieure de la face arrière 10b comporte deux orifices de raccordement (non représentés) obturés par des bouchons standardisés. Les orifices de raccordement prévus sur les deux modèles de boîtes sont situés en face de bouchons 60 amovibles et étanches placés sur le mur arrière de la protection biologique 14, comme le montre la figure 1.The analysis boxes 10 which are devoid of means for introducing and extracting the products are distinguished from the previous ones by the fact that the lower part of the rear face 10b comprises two connection orifices (not shown) closed by standardized plugs. The connection orifices provided on the two models of boxes are located opposite removable and waterproof plugs 60 placed on the rear wall of the biological protection 14, as shown in FIG. 1.

Afin de compléter le caractère modulaire des boîtes d'analyse 10 qui viennent d'être décrites, les autres éléments de la chaîne blindée d'analyse, et notamment la protection biologique 14, sont également réalisés de façon modulaire, à l'aide d'un certain nombre de pièces standardisées.In order to complete the modular nature of the analysis boxes 10 which have just been described, the other elements of the armored analysis chain, and in particular the biological protection 14, are also produced in a modular fashion, using a number of standardized parts.

Ainsi et comme l'illustre en particulier la figure 1, la protection biologique 14 est constituée d'un certain nombre d'éléments standardisés qui sont avantageusement réalisés en fonte, afin d'en faciliter la fabrication.So and as illustrated in particular Figure 1, the biological protection 14 consists of a number of standardized elements which are advantageously made of cast iron, in order to facilitate manufacture.

Dans la partie de la protection biologique 14 qui entoure chacune des boîtes d'analyse 10, ces éléments standardisés comprennent un mur avant standardisé 62, une dalle inférieure standardisée 64, un mur inférieur arrière standardisé 66, les éléments supérieurs 38, déjà décrits, démontables et standardisés du mur arrière, et un toit standardisé 68. La protection biologique est complétée, dans les parties situées entre deux boîtes 10 adjacentes, par un bouchon supérieur standardisé 70 et un pilier arrière standardisé 72. Enfin, elle est fermée aux deux extrémités de la chaîne blindée d'analyse par des murs d'extrémités droite et gauche standardisés 74 et 76.In the part of the biological protection 14 which surrounds each of the analysis boxes 10, these standardized elements include a standardized front wall 62, a standardized lower slab 64, a standardized rear lower wall 66, the upper elements 38, already described, which can be dismantled and standardized of the rear wall, and a standardized roof 68. The biological protection is supplemented, in the parts located between two adjacent boxes 10, by a standardized upper cap 70 and a standardized rear pillar 72. Finally, it is closed at both ends of the armored chain of analysis by standardized right and left end walls 74 and 76.

Ces différentes pièces existent toutes en un seul modèle, à l'exception du mur inférieur arrière standardisé 66, pour une épaisseur donnée de la protection biologique. Bien entendu, si des chaînes blindées d'analyse doivent comporter des protections biologiques d'épaisseurs différentes, en fonction de l'activité interne de la boîte, un modèle de chacun des éléments standardisés précités est prévu pour chacune de ces épaisseurs.These different parts all exist in a single model, with the exception of the standard rear wall 66, for a given thickness of biological protection. Of course, if the armored analysis chains must include biological protections of different thicknesses, depending on the internal activity of the box, a model of each of the aforementioned standardized elements is provided for each of these thicknesses.

En ce qui concerne le mur inférieur arrière standardisé 66, il en existe deux modèles pour chaque épaisseur de protection biologique, selon que la boîte 10 correspondante est ou non équipée de moyens pour introduire et extraire les produits. Lorsque la boîte 10 est équipée de tels moyens, le mur inférieur standardisé 66 comporte le passage 48 apte à être obturé par la porte à masselottes 50, ainsi qu'un bouchon 60, comme on l'a représenté sur la droite de la figure 1. Au contraire, lorsque la boîte 10 est dépourvue de moyens pour introduire et extraire des produits, le mur inférieur arrière standardisé 66 ne comporte que deux bouchons 60, comme on l'a représenté sur la gauche de la figure 1.As regards the standardized rear lower wall 66, there are two models for each thickness of biological protection, depending on whether the corresponding box 10 is or is not equipped with means for introducing and extracting the products. When the box 10 is equipped with such means, the standardized lower wall 66 comprises the passage 48 able to be closed by the flyweight door 50, as well as a plug 60, as shown on the right of FIG. 1 On the contrary, when the box 10 is devoid means for introducing and extracting products, the standardized rear lower wall 66 has only two plugs 60, as shown on the left in FIG. 1.

Chacun des murs avant standardisés 62 de la protection biologique 14 est muni approximativement en son centre du hublot 20 et comporte au-dessus de ce dernier deux trous de passage pour les télémanipulateurs 16. Le mur avant standardisé 62 comprend de plus les bouchons 25 (figure 3) permettant d'accéder aux éléments de maintien de la paroi transparente 18 de la boîte 10 correspondante. Ce mur repose par son bord inférieur sur la dalle inférieure standardisée 64, à laquelle il est fixé.Each of the standardized front walls 62 of the biological protection 14 is provided approximately in its center with the porthole 20 and comprises above the latter two through holes for the remote manipulators 16. The standardized front wall 62 further includes the plugs 25 (FIG. 3) providing access to the retaining elements of the transparent wall 18 of the corresponding box 10. This wall rests by its lower edge on the standardized lower slab 64, to which it is fixed.

La dalle inférieure standardisée 64 comporte quant à elle des organes d'appui et des pions de positionnement 77 (figures 2 et 3) par lesquels la boîte d'analyse 10 correspondante repose en un emplacement bien déterminé sur la dalle 64. Chacune des dalles inférieures standardisées 64 repose quant à elle sur un châssis standardisé 78, équipé de vis de mise à niveau (non représentées) et supportant l'ensemble de la protection biologique 14 associé à chacune des boîtes 10, ainsi que la boîte proprement dite et des éléments annexes qui seront décrits par la suite.The standardized lower slab 64 comprises support members and positioning pins 77 (FIGS. 2 and 3) by which the corresponding analysis box 10 rests in a well-determined location on the slab 64. Each of the lower slabs 64 is based on a standardized chassis 78, equipped with leveling screws (not shown) and supporting all of the biological protection 14 associated with each of the boxes 10, as well as the box itself and the ancillary elements which will be described later.

Le toit standardisé 68 comporte quant à lui les bouchons 26 et 36 permettant respectivement d'accéder à la paroi transparente 18 et aux composants d'analyse 28 de la boîte d'analyse 10 placée en dessous de ce toit.The standardized roof 68 comprises plugs 26 and 36 respectively allowing access to the transparent wall 18 and to the analysis components 28 of the analysis box 10 placed below this roof.

Pour assurer la communication étanche entre les boîtes d'analyse 10 par les passages 12 entre les orifices de liaison 40 des boîtes adjacentes, la chaîne blindée d'analyse comprend de plus des cloisons intermédiaires standardisées telles que celle qui est illustrée en 80 sur la figure 1. Selon la nature des opérations qui sont effectuées dans les boîtes adjacentes 10 séparées par cette cloison intermédiaire 80, trois modèles différents de cloisons peuvent être utilisés. Deux de ces modèles vont à présent être décrits, en se référant successivement aux figures 5 et 6 et aux figures 7 à 10. Dans tous les cas, la cloison intermédiaire 80 est associée au bouchon supérieur 70 et au pilier arrière 72, afin d'assurer la liaison et le maintien entre les parties avant et arrière de la protection biologique 14 dans la chaîne blindée.To ensure sealed communication between the analysis boxes 10 through the passages 12 between the connection orifices 40 of the adjacent boxes, the shielded analysis chain further comprises standardized intermediate partitions such as that which is illustrated. at 80 in FIG. 1. Depending on the nature of the operations which are carried out in the adjacent boxes 10 separated by this intermediate partition 80, three different models of partitions can be used. Two of these models will now be described, referring successively to Figures 5 and 6 and Figures 7 to 10. In all cases, the intermediate partition 80 is associated with the upper plug 70 and the rear pillar 72, in order to ensuring the connection and maintenance between the front and rear parts of the biological protection 14 in the armored chain.

Le modèle de cloison intermédiaire standardisé non représenté sur les figures est le plus simple. Il est constitué par une cloison pleine, réalisée par exemple en fonte, simplement pourvu d'un passage circulaire aligné avec les orifices de liaison 40 des boîtes entre lesquelles cette cloison est placée. Dans le cas où une telle cloison intermédiaire est utilisée, les orifices de liaison des boîtes 10 adjacentes doivent être équipés de portes d'obturation standardisées 82 telles qu'illustrées sur la figure 1.The standard intermediate partition model not shown in the figures is the simplest. It consists of a solid partition, made for example of cast iron, simply provided with a circular passage aligned with the connection orifices 40 of the boxes between which this partition is placed. In the case where such an intermediate partition is used, the connection orifices of the adjacent boxes 10 must be fitted with standardized shutter doors 82 as illustrated in FIG. 1.

La cloison pleine constituant ce premier modèle de cloison intermédiaire 80 est munie sur ses deux faces de rainures de guidages verticales facilitant l'introduction et le retrait des boîtes d'analyse 10, après enlèvement du toit standardisé 68 placé au-dessus de chaque boîte et des éléments supérieurs 38 du mur arrière de la protection biologique.The solid partition constituting this first model of intermediate partition 80 is provided on its two faces with vertical guide grooves facilitating the introduction and removal of the analysis boxes 10, after removal of the standardized roof 68 placed above each box and upper elements 38 of the rear wall of the biological protection.

Dans un deuxième modèle de cloison intermédiaire standardisée, illustré sur les figures 4 à 6 et désigné de façon générale par la référence 80a, cette cloison intermédiaire comprend également une cloison pleine 84, réalisée de préférence en fonte pour en faciliter la fabrication. Cette cloison pleine 84 est positionnée et fixée sur les dalles inférieures standardisées 64 supportant les deux boîtes 10 adjacentes, par exemple au moyen de pions de centrage 86 et de vis 88.In a second model of standardized intermediate partition, illustrated in FIGS. 4 to 6 and generally designated by the reference 80a, this intermediate partition also comprises a solid partition 84, preferably made of cast iron to facilitate its manufacture. This solid partition 84 is positioned and fixed on the lower slabs standardized 64 supporting the two adjacent boxes 10, for example by means of centering pins 86 and screws 88.

En face des orifices de liaison 40 formés dans les boîtes adjacentes 10, la cloison pleine 84 supporte un tunnel tubulaire 90, réalisé par exemple en acier inoxydable. Ce tunnel délimite intérieurement le passage 12 assurant la communication entre les boîtes 10 au travers des orifices de liaison 40 de ces dernières.Opposite the connection orifices 40 formed in the adjacent boxes 10, the solid partition 84 supports a tubular tunnel 90, made for example of stainless steel. This tunnel internally delimits the passage 12 ensuring communication between the boxes 10 through the connection orifices 40 of the latter.

Des soufflets métalliques standardisés 92a sont fixés, par exemple au moyen de vis (non représentées), sur les brides 42 délimitant les orifices de liaison 40 dans chacune des boîtes d'analyse 10. Les extrémités opposées des soufflets métalliques 92a sont raccordées de façon étanche sur les extrémités du tunnel 90 par des colliers à chaînes 94a dont une seule a été mise en place sur la droite de la figure 4, et illustrée à plus grande échelle sur la figure 6.Standardized metal bellows 92a are fixed, for example by means of screws (not shown), on the flanges 42 delimiting the connection orifices 40 in each of the analysis boxes 10. The opposite ends of the metal bellows 92a are tightly connected on the ends of the tunnel 90 by chain collars 94a, only one of which has been placed on the right of FIG. 4, and illustrated on a larger scale in FIG. 6.

Les maillons des colliers à chaînes 94a comportent une gorge intérieure pourvue de flancs inclinés qui viennent coopérer avec des surfaces complémentaires formées sur des brides d'extrémité du tunnel 90 et des soufflets métalliques 92a. Cet agencement permet, lors du serrage des colliers à chaînes 94a, d'appliquer de façon étanche les brides formées aux extrémités du tunnel 90 contre les brides formées aux extrémités des soufflets métalliques 92a.The links of the chain collars 94a have an inner groove provided with inclined sides which cooperate with complementary surfaces formed on the end flanges of the tunnel 90 and metal bellows 92a. This arrangement makes it possible, when tightening the chain collars 94a, to apply the flanges formed at the ends of the tunnel 90 tightly against the flanges formed at the ends of the metal bellows 92a.

Chacun des colliers à chaînes 94a est formé de maillons 95a, articulés entre eux par des biellettes 96a. Le serrage est assuré par un écrou 97a vissé sur une tige filetée 98a articulée sur l'un des maillons d'extrémité, cet écrou pouvant être reçu dans une empreinte formée dans l'autre maillon d'extrémité.Each of the chain collars 94a is formed of links 95a, hinged together by links 96a. The tightening is ensured by a nut 97a screwed onto a threaded rod 98a articulated on one of the end links, this nut being able to be received in an imprint formed in the other end link.

Lorsqu'ils sont ouverts, les colliers à chaînes 94a sont reçus dans des berceaux 99a fixés sur le tunnel 90. Un crochet 100a, formé sur le maillon d'extrémité portant l'empreinte précitée, est alors placé sur une tige 101a (figure 6) solidaire de la cloison 84. Les deux extrémités du collier à chaîne 94a restent donc accessibles par le haut lorsque le collier est ouvert et cette position d'ouverture du collier à chaîne permet la mise en place et l'enlèvement des soufflets métalliques 92a.When open, the collars chains 94a are received in cradles 99a fixed on the tunnel 90. A hook 100a, formed on the end link carrying the aforementioned imprint, is then placed on a rod 101a (Figure 6) secured to the partition 84. The two ends of the chain collar 94a therefore remain accessible from above when the collar is open and this open position of the chain collar allows the establishment and removal of the metal bellows 92a.

La cloison intermédiaire standardisée 80a comprend de plus une tablette mobile 102a permettant le transfert d'éléments d'analyse entre les boîtes 10 adjacentes. La tablette 102a roule sur un support 103a qui repose sur des appuis 104a fixés sur les brides 42, à l'intérieur de chacune des boîtes 10. La tablette mobile 102a et son support 103a peuvent être introduits ou évacués par le conteneur 52, dans l'une des boîtes 10 permettant d'accéder à ce conteneur.The standardized intermediate partition 80a further comprises a mobile shelf 102a allowing the transfer of analysis elements between the adjacent boxes 10. The tablet 102a rolls on a support 103a which rests on supports 104a fixed on the flanges 42, inside each of the boxes 10. The mobile tablet 102a and its support 103a can be introduced or removed by the container 52, in the one of the boxes 10 providing access to this container.

Comme dans le modèle décrit précédemment, la cloison pleine 84 comporte, dans sa partie située vers l'avant de la chaîne blindée d'analyse, des guides latéraux (non représentés) permettant le pré-guidage des boîtes d'analyse 10 lors de leur mise en place et de leur retrait, après démontage du toit de la protection biologique.As in the model described above, the solid partition 84 comprises, in its part located towards the front of the armored analysis chain, lateral guides (not shown) allowing the pre-guiding of the analysis boxes 10 during their installation and removal after removal of the biological protection roof.

On décrira à présent en se référant aux figures 7 à 9 le troisième modèle de cloison intermédiaire standardisée pouvant être utilisé dans la chaîne blindée. La cloison intermédiaire standardisée est désignée dans ce cas par la référence 80b.We will now describe with reference to FIGS. 7 to 9 the third model of standardized intermediate partition which can be used in the armored chain. The standardized intermediate partition is designated in this case by the reference 80b.

Ce troisième modèle se distingue principalement du précédent par le fait qu'il est équipé d'une porte dont la commande est motorisée. Dans une variante (non représentée), la commande de la porte est effectuée manuellement. Ce troisième modèle se distingue également du précédent par le fait qu'il assure une liaison étanche entre deux boîtes 10 consécutives et qu'il constitue une protection biologique entre ces boîtes. Ce modèle permet donc d'isoler les boîtes les une par rapport aux autres et de changer une boîte quelconque de la chaîne en cas de nécessité, en intervenant uniquement sur le module concerné.This third model differs mainly from the previous one by the fact that it is equipped with a door whose control is motorized. In a variant (not shown), the door is controlled manually. This third model also stands out from the previous one by the fact that it provides a sealed connection between two consecutive boxes 10 and that it constitutes biological protection between these boxes. This model therefore makes it possible to isolate the boxes one from the other and to change any box in the chain if necessary, by intervening only on the module concerned.

Dans le modèle illustré sur les figures 7 à 9, la cloison intermédiaire standardisée 80b comprend un bâti mécanosoudé 105 dans lequel peut coulisser verticalement une porte blindée 106, gainée d'acier inoxydable. Le bâti mécanosoudé 105 comporte dans sa partie inférieure une ouverture circulaire formant le passage 12, cette ouverture étant ouverte ou fermée selon que la porte 106 est en position haute ou en position basse.In the model illustrated in FIGS. 7 to 9, the standardized intermediate partition 80b comprises a mechanically welded frame 105 in which an armored door 106 can slide vertically, sheathed in stainless steel. The mechanically welded frame 105 has in its lower part a circular opening forming the passage 12, this opening being open or closed depending on whether the door 106 is in the high position or in the low position.

Comme l'illustre plus précisément la figure 9, le passage 12 se prolonge de part et d'autre du bâti mécanosoudé 105 par deux manchons 108 soudés sur le bâti et terminés à leurs extrémités par des brides. Comme dans le modèle décrit précédemment en se référant aux figures 4 à 6, ces brides présentent des faces inclinées complémentaires des flancs inclinés d'une gorge intérieure formée dans les maillons d'un collier à chaîne 94b servant à fixer de façon étanche une bride d'extrémité d'un soufflet métallique 92b sur le manchon 108. L'extrémité opposée de chacun des soufflets métalliques 92b comporte une seconde bride qui est fixée de façon étanche sur la bride 42 de la boîte 10 correspondante par exemple au moyen de vis 110.As illustrated more precisely in FIG. 9, the passage 12 is extended on either side of the mechanically welded frame 105 by two sleeves 108 welded to the frame and terminated at their ends by flanges. As in the model described above with reference to FIGS. 4 to 6, these flanges have inclined faces complementary to the inclined flanks of an internal groove formed in the links of a chain collar 94b used to tightly fix a flange d end of a metal bellows 92b on the sleeve 108. The opposite end of each of the metal bellows 92b comprises a second flange which is tightly fixed on the flange 42 of the corresponding box 10 for example by means of screws 110.

Comme l'illustrent notamment les figures 7 et 8 chacun des colliers à chaînes 94b est guidé et retenu dans un berceau 99b qui est fixé sur le manchon 108 correspondant, par exemple par des vis (non représentées). Comme dans le modèle de cloison intermédiaire standardisée décrit précédemment, les berceaux 99b permettent d'accéder par le dessus aux extrémités supérieures des colliers à chaînes 94b, lorsque ceux-ci sont ouverts. De plus, ces berceaux sont ouverts vers le haut de façon à permettre la mise en place et l'enlèvement des soufflets métalliques 92b.As illustrated in particular in FIGS. 7 and 8, each of the chain collars 94b is guided and retained in a cradle 99b which is fixed to the corresponding sleeve 108, for example by screws (not shown). As in the intermediate partition model standardized described above, the cradles 99b allow access from above to the upper ends of the chain collars 94b, when these are open. In addition, these cradles are open upward so as to allow the establishment and removal of the metal bellows 92b.

La commande de la montée et de la descente de la porte 106 à l'intérieur du bâti mécanosoudé est assurée, au travers du bouchon supérieur 70 de la protection biologique, par l'intermédiaire d'une vis 111 (figure 8), solidaire de la porte 106, et d'un écrou rotatif 112. L'écrou 112 traverse également la partie du bâti 105 située au-dessus de la porte 106 et, au-dessus du bouchon supérieur 70, il est entraîné en rotation par un motoréducteur 114 logé dans un carter 116.The control of the ascent and descent of the door 106 inside the mechanically welded frame is ensured, through the upper plug 70 of the biological protection, by means of a screw 111 (FIG. 8), integral with the door 106, and of a rotary nut 112. The nut 112 also passes through the part of the frame 105 situated above the door 106 and, above the upper plug 70, it is rotated by a geared motor 114 housed in a housing 116.

Un volant 118 peut être placé sur un carré de manoeuvre 119 situé à l'extrémité supérieure de l'arbre de sortie du motoréducteur 114, au-dessus du carter 116, afin de commander une ouverture ou une fermeture manuelle de la porte 106, en cas de nécessité.A flywheel 118 can be placed on an operating square 119 located at the upper end of the output shaft of the gearmotor 114, above the casing 116, in order to control a manual opening or closing of the door 106, in when necessary.

A l'intérieur du carter 116 sont également logées deux butées de fin de course 120 (figure 8), sensibles à la rotation d'un disque 121 entraîné en rotation par l'arbre d'entraînement du système vis-écrou 112, par l'intermédiaire d'une courroie d'entraînement 122 et d'un motoréducteur 123.Inside the casing 116 are also housed two limit stops 120 (FIG. 8), sensitive to the rotation of a disc 121 driven in rotation by the drive shaft of the screw-nut system 112, by the 'via a drive belt 122 and a geared motor 123.

Afin d'assurer l'obturation étanche du passage 12 lorsque la porte 106 est fermée, cette dernière est équipée, sur chacune de ses faces, d'un joint gonflable 124 logé dans une gorge et qui entoure le passage 12 lorsque la porte est fermée. Le gonflement des joints 124, commandé au travers d'une tuyauterie verticale télescopique 125, a donc pour effet d'appliquer ces joints de façon étanche contre les faces radiales de l'évidement dans lequel coulisse la porte 106, à l'intérieur du bâti 105.In order to ensure the tight closure of the passage 12 when the door 106 is closed, the latter is equipped, on each of its faces, with an inflatable seal 124 housed in a groove and which surrounds the passage 12 when the door is closed . The swelling of the seals 124, controlled through a telescopic vertical pipe 125, therefore has the effect of applying these seals sealingly against the radial faces of the recess in which the door 106 slides, inside the frame 105.

Comme pour le modèle de cloison intermédiaire standardisée décrit précédemment en se référant aux figures 4 à 6, la cloison 80b illustrée sur la figure 7, comprend une tablette de transfert 102b au moyen de laquelle des éléments d'analyse peuvent être transportés d'une boîte dans l'autre. Cette tablette 102b roule sur un support 103b qui repose sur des appuis 104b fixés à l'intérieur de chacune des boîtes 10.As for the standardized intermediate partition model described above with reference to FIGS. 4 to 6, the partition 80b illustrated in FIG. 7, includes a transfer shelf 102b by means of which analysis elements can be transported from a box in the other. This tablet 102b rolls on a support 103b which rests on supports 104b fixed inside each of the boxes 10.

Le positionnement et la fixation de la cloison intermédiaire standardisée 80b sur les dalles inférieures standardisées 64 sont également assurés par des centreurs 86 solidaires de la dalle inférieure standardisée 64 correspondante et par des vis 88.The positioning and fixing of the standardized intermediate partition 80b on the standardized lower slabs 64 are also ensured by centralizers 86 secured to the corresponding standardized lower slab 64 and by screws 88.

Des guides latéraux (non représentés) situés vers l'avant de la chaîne sont montés sur le bâti 104 afin de permettre le pré-guidage des boîtes d'analyse 10 lors de leur mise en place et de leur retrait.Lateral guides (not shown) located towards the front of the chain are mounted on the frame 104 in order to allow the pre-guiding of the analysis boxes 10 during their installation and their removal.

La conception modulaire de la chaîne blindée d'analyse représentée sur les figures se retrouve également dans les pupitres et dans les circuits qui permettent de commander les composants d'analyse 28 montés sur chacune des boîtes d'analyse ainsi que l'entrée et la sortie des fluides nécessaires à ces analyses et aux opérations qui en découlent.The modular design of the armored analysis chain shown in the figures is also found in the consoles and in the circuits which make it possible to control the analysis components 28 mounted on each of the analysis boxes as well as the input and the output. fluids necessary for these analyzes and the operations resulting therefrom.

Ainsi, le caractère modulaire de la chaîne blindée concerne également des moyens de ventilation associés à chacune des boîtes d'analyse 10, un pupitre supérieur à partir duquel peut notamment être commandée l'introduction dans les boîtes d'analyse des différents fluides nécessaires à ces analyses, un pupitre inférieur à partir duquel peuvent notamment être commandés les asservissements pneumatiques des différents composants d'analyse 28, ainsi que les structures mécaniques permettant de relier le siphon 43 soudé dans le fond de chacune des boîtes d'analyse 10 à un caniveau égout d'évacuation des fluides usagés.Thus, the modular nature of the armored chain also relates to ventilation means associated with each of the analysis boxes 10, an upper console from which can in particular be controlled the introduction into the analysis boxes of the various fluids necessary for these analyzes, a lower console from which the pneumatic servocontrol of the various analysis components 28 can in particular be controlled, as well as the mechanical structures allowing to connect the siphon 43 welded in the bottom of each of the analysis boxes 10 to a drain channel for discharging used fluids.

En ce qui concerne tout d'abord les moyens de ventilation associés à chacune des boîtes d'analyse 10, ils comprennent, comme l'illustre notamment la figure 2 un ensemble de ventilation standardisé 126 monté en dessous du châssis 78 supportant la boîte considérée. Cet ensemble de ventilation standardisé comprend pour l'essentiel un conduit d'alimentation pneumatique 128 et un conduit de reprise de ventilation 130, orientés parallèlement l'un à l'autre selon la direction longitudinale de la chaîne blindée. Cet ensemble de ventilation standardisé comprend de plus des supports des conduits 128 et 130, des vannes d'isolement, ainsi qu'un boîtier 132 recevant un filtre d'extraction, démontable au moyen d'un sac de vinyle.As regards first of all the ventilation means associated with each of the analysis boxes 10, they comprise, as illustrated in particular in FIG. 2, a standardized ventilation assembly 126 mounted below the frame 78 supporting the box in question. This standardized ventilation assembly essentially comprises a pneumatic supply duct 128 and a ventilation return duct 130, oriented parallel to one another in the longitudinal direction of the armored chain.

La liaison entre les conduits 128 et 130 de deux châssis 78 adjacents se fait par soudure d'un manchon non standardisé, lors du montage de la chaîne blindée.The connection between the conduits 128 and 130 of two adjacent frames 78 is made by welding a non-standardized sleeve, during assembly of the armored chain.

Un pupitre supérieur de commande standardisé 138 est fixé sur le mur avant 62 de la protection biologique 14 associée à chacune des boîtes 10. Tous les pupitres 138 sont réalisés selon un modèle unique et comprennent un châssis, fermé par des panneaux et supportant, par exemple, douze tuyauteries. Dix de ces tuyauteries sont destinées à l'alimentation des réactifs, alors qu'une tuyauterie permet d'acheminer un liquide de rinçage et que la dernière tuyauterie permet d'alimenter une rampe de lavage et de décontamination souple.A standardized upper control desk 138 is fixed to the front wall 62 of the biological protection 14 associated with each of the boxes 10. All of the desks 138 are produced according to a single model and include a frame, closed by panels and supporting, for example, twelve pipes. Ten of these pipes are intended for the supply of reagents, while one pipe makes it possible to convey a rinsing liquid and that the last pipe makes it possible to feed a flexible washing and decontamination ramp.

La face avant inclinée de chaque pupitre 138 porte en son centre six vannes pour l'alimentation des réactifs et trois robinets adaptés aux fonctions de rinçage, décontamination et lavage. Les vannes d'alimentation des réactifs sont raccordées sur les extrémités des tuyauteries 44 de chacune des boîtes 10, suivant les spécifications de celles-ci. Chaque pupitre 138 comprend de plus des moyens de contrôle de la dépression régnant dans la boîte d'analyse 10 correspondante.The inclined front face of each console 138 carries in its center six valves for supplying the reagents and three taps adapted to the rinsing, decontamination and washing functions. The reagent supply valves are connected to the ends of the pipes 44 of each of the boxes 10, according to the specifications thereof. Each console 138 further comprises means for controlling the vacuum prevailing in the corresponding analysis box 10.

Le raccordement des tuyauteries entre les pupitres 138 s'effectue au moyen de raccords bout à bout.The pipes are connected between the consoles 138 using end-to-end fittings.

Pour assurer le raccordement des six vannes de distribution de chacun des pupitres supérieurs 138 sur les deux séries de trois tuyauteries 44 associées à chacune des boîtes d'analyse 10, on implante dans le mur avant de la protection biologique, aux extrémités du pupitre 138, deux ensembles d'arrivée de réactifs 140, qui permettent le guidage des tuyauteries souples 44 raccordés aux vannes de distribution montées dans le pupitre 138.To ensure the connection of the six distribution valves of each of the upper panels 138 on the two series of three pipes 44 associated with each of the analysis boxes 10, the front wall of the biological protection is installed at the ends of the panel 138, two reagent inlet sets 140, which allow the flexible pipes 44 connected to the distribution valves mounted in the console 138 to be guided.

A chacun des pupitres 138 est également associé un ensemble standardisé 142 d'arrivée de fluide de lavage, qui est situé au centre du pupitre supérieur 138 et traverse la protection biologique. Cet ensemble permet l'alimentation de la boîte 10 correspondante en fluide de lavage et de rinçage, depuis le pupitre supérieur 138.Each of the desks 138 is also associated with a standardized assembly 142 of washing fluid inlet, which is located in the center of the upper desk 138 and passes through the biological protection.

A l'une des extrémités de la chaîne blindée d'analyse, choisie en fonction de l'implantation des tuyauteries d'alimentation, notamment en air et en réactif, à l'extérieur de la chaîne, est implanté un pupitre d'alimentation standardisé 146 (figure 1), réalisé selon deux modèles droit et gauche. Ce pupitre d'alimentation 146 prolonge verticalement les pupitres inférieur 144 et supérieur 138 extrêmes de la chaîne et comporte une commande générale d'alimentation en air du pupitre inférieur, équipé d'un manomètre de contrôle. Ce pupitre d'alimentation standardisé comprend également les supports et tuyauteries d'alimentation du pupitre inférieur, un capotage de recouvrement de ces tuyauteries, un ensemble de conditionnement d'air pour l'alimentation de la chaîne blindée, ainsi que divers robinets et vannes associés aux circuits.At one end of the armored analysis chain, chosen according to the location of the supply pipes, in particular air and reagent, outside the chain, there is a standardized supply desk 146 (figure 1), produced according to two models, right and left. This feed console 146 vertically extends the consoles lower 144 and upper 138 extremes of the chain and includes a general air supply control for the lower console, equipped with a pressure gauge. This standardized supply console also includes the supports and supply pipes for the lower console, a cover for covering these pipes, an air conditioning unit for supplying the armored chain, as well as various associated taps and valves. to circuits.

A l'extrémité opposée de la chaîne blindée sont prévus un pupitre supérieur d'extrémité standardisé 148 et un pupitre inférieur d'extrémité standardisé 150. Ces deux pupitres d'extrémité peuvent également être réalisés selon deux modèles, selon qu'ils sont prévus pour être placés aux extrémités droite ou gauche de la chaîne.At the opposite end of the armored chain are provided a standardized upper end console 148 and a standardized lower end console 150. These two end consoles can also be produced in two models, depending on whether they are designed to be placed at the right or left ends of the chain.

Chaque pupitre supérieur d'extrémité standardisé comprend un capot et des obturateurs d'extrémité des lignes d'alimentation contenues dans les pupitres supérieurs standardisés 138.Each standardized upper end console comprises a cover and end shutters for the supply lines contained in the standardized upper consoles 138.

Le pupitre inférieur d'extrémité standardisé 150 est constitué d'une plaque d'obturation latérale à fixer sur le pupitre inférieur 144 adjacent de la chaîne blindée.The standardized lower end console 150 consists of a lateral closing plate to be fixed on the lower console 144 adjacent to the armored chain.

Enfin, on voit sur la figure 2 que le siphon 43 soudé dans le fond de chacune des boîtes d'analyse 10 est relié à un caniveau 152 prévu dans le sol de la cellule par un élément de liaison standardisé 154. Cet élément est constitué d'un conduit vertical reliant le siphon 43 à la tuyauterie du caniveau, d'une protection biologique entourant ce conduit et de mâchoires de protection entourant le raccord de jonction entre le conduit et le siphon et permettant d'intervenir sur ce raccord.Finally, it can be seen in FIG. 2 that the siphon 43 welded into the bottom of each of the analysis boxes 10 is connected to a channel 152 provided in the floor of the cell by a standardized connecting element 154. This element consists of 'a vertical conduit connecting the siphon 43 to the piping of the gutter, a biological protection surrounding this conduit and protective jaws surrounding the junction connection between the conduit and the siphon and allowing to intervene on this connection.

L'extrémité inférieure de l'élément de liaison standardisé 154 débouche sur un ensemble de dalles standardisées 156, qui constitue la protection biologique du caniveau 152 dans toute la zone couverte par la boîte 10, par la partie correspondante de la protection biologique 14 et par le châssis 78.The lower end of the connecting element standardized 154 leads to a set of standardized slabs 156, which constitutes the biological protection of the gutter 152 in the entire area covered by the box 10, by the corresponding part of the biological protection 14 and by the frame 78.

Grâce à la configuration qui vient d'être décrite en se référant aux figures annexées, on comprend aisément que l'étude d'une nouvelle chaîne blindée est grandement facilitée par l'utilisation des éléments standardisés qui viennent d'être décrits. Le coût de cette étude ainsi que celui de sa fabrication s'en trouve par conséquent très sensiblement réduit.Thanks to the configuration which has just been described with reference to the appended figures, it is easily understood that the study of a new armored chain is greatly facilitated by the use of the standardized elements which have just been described. The cost of this study as well as that of its manufacture is therefore very significantly reduced.

Par ailleurs, la structure modulaire de la chaîne blindée d'analyse selon l'invention permet d'intervenir dans des conditions particulièrement favorables en un endroit quelconque de la chaîne, ou même de transformer celle-ci. En particulier, la maintenance se trouve grandement facilitée, de même que l'adaptation de la chaîne blindée à toute évolution imprévisible lors de sa conception. Une évolution est ainsi possible aussi bien dans le choix des composants d'analyse 28 associés à une boîte d'analyse 10 qu'en ce qui concerne la boîte d'analyse dans son ensemble.Furthermore, the modular structure of the armored analysis chain according to the invention makes it possible to intervene under particularly favorable conditions at any point of the chain, or even to transform the latter. In particular, maintenance is greatly facilitated, as is the adaptation of the armored chain to any unforeseeable development during its design. An evolution is thus possible as well in the choice of the analysis components 28 associated with an analysis box 10 as with regard to the analysis box as a whole.
