Abstract

At the bottom of a shell (5), a temporary storage can (4) for vacuumed waste comprises a dish (31) that is pushed upwards by a spring but lowers when flexible bags (13) located above the dish (31) fill up with waste. The position of the lid (13) is continuously monitored so that it is possible to stop the vacuuming operation only once the can is full enough but before getting clogged.

Description

RESERVOIR DE DECHETS ASPIRES  ASPIRE WASTE TANK
DESCRIPTION DESCRIPTION
Le sujet de l'invention est un réservoir de déchets aspirés, à utiliser en association à un aspirateur et dont l'intérêt est plus particulièrement marqué pour l'entreposage de déchets dangereux, radioactifs par exemple. The subject of the invention is a tank of aspired waste, to be used in combination with a vacuum cleaner and whose interest is particularly marked for the storage of hazardous waste, radioactive for example.
Des aspirateurs industriels comprenant un réservoir amovible de retenue des déchets sont déjà connus. Certains modèles comprennent, comme on le voit aux figures 1 et 2, un réservoir consistant en un bidon filtrant 1, muni de raccords 2 et 3 respectifs à un conduit d'entrée 41 et un conduit de sortie 42. Un aspirateur 43 est branché à l'extrémité libre du conduit de sortie 42 et aspire de l'air extérieur et des matières solides environnantes, jusqu'au bidon filtrant 1. Le volume de ce dernier est divisé en deux parties par un filtre 44 de forme cylindrique. Le raccord 2 d'entrée débouche sous le filtre 44, dans un volume inférieur 45 où les déchets s'accumulent, tandis que l'air, remontant par les côtés et traversant le filtre 44, quitte le bidon filtrant 1 par le raccord 3 de sortie et poursuit son chemin vers l'aspirateur 43. Un tel dispositif, efficace en soi, a cependant les inconvénients qu'un volume important du bidon filtrant 1 reste inoccupé, et que l'état de remplissage complet est difficile à évaluer. Dans le cas de déchets radioactifs ou plus généralement dangereux, le bidon filtrant 1 est à usage unique et mis de côté dès qu'on estime qu'il est rempli : cela implique soit des sous-remplissages et donc un gaspillage de matériel et de volume d'entreposage, soit des sur-remplissages qui peuvent avoir pour conséquence des pertes accidentelles de déchets au moment du démontage du bidon filtrant 1, si par exemple ils occupaient une partie du volume du raccord 2 d'entrée. Enfin, des colmatages précoces peuvent se produire.  Industrial vacuum cleaners comprising a removable holding tank are already known. Some models include, as seen in Figures 1 and 2, a reservoir consisting of a filter canister 1, provided with respective connectors 2 and 3 to an inlet duct 41 and an outlet duct 42. A vacuum cleaner 43 is connected to the free end of the outlet duct 42 and draws outside air and surrounding solids to the filter can 1. The volume of the latter is divided into two parts by a filter 44 of cylindrical shape. The inlet connection 2 opens under the filter 44, in a lower volume 45 where the waste accumulates, while the air, rising from the sides and passing through the filter 44, leaves the filter container 1 through the connection 3 of Exit and continues its path to the vacuum cleaner 43. Such a device, effective in itself, however, has the disadvantages that a large volume of the filter canister 1 remains unoccupied, and that the complete filling state is difficult to evaluate. In the case of radioactive or more generally dangerous waste, the filter can 1 is disposable and set aside as soon as it is considered to be filled: this implies either under-filling and thus a waste of material and volume. storage, or over-filling which may result in accidental waste losses at the time of dismantling the filter container 1, if for example they occupied part of the volume of the inlet fitting 2. Finally, early clogging can occur.
L'objet principal de l'invention est donc de filtrer et récolter des déchets solides tout en suivant dans de bonnes conditions le remplissage du réservoir, en premier lieu son remplissage physique, éventuellement son remplissage radiologique, par exemple par comparaison à un seuil de radioactivité toléré, et son degré de colmatage. L'invention est applicable à l'aspiration de déchets dans le domaine du nucléaire, mais pas uniquement. The main object of the invention is therefore to filter and collect solid waste while following in good conditions the filling of the reservoir, firstly its physical filling, possibly its radiological filling, for example by comparison with a threshold of radioactivity tolerated, and its degree of clogging. The invention is applicable to the aspiration of waste in the nuclear field, but not only.
Un autre objet de l'invention est de limiter l'encombrement final des déchets aspirés grâce à un agencement judicieux, permettant un remplissage plus important, du réservoir. Un autre est de maintenir cependant la radioactivité de déchets nucléaires à un niveau acceptable et donc de limiter si nécessaire le remplissage du réservoir. Un autre est de travailler autant que possible à distance du réservoir pendant son démontage, en utilisant des outils tels que des télémanipulateurs.  Another object of the invention is to limit the final size of the waste vacuumed by a judicious arrangement for a greater filling of the tank. Another is to maintain the radioactivity of nuclear waste at an acceptable level and therefore to limit the filling of the tank if necessary. Another is to work as much as possible away from the tank during disassembly, using tools such as remote manipulators.
Sous une forme générale, l'invention concerne un réservoir de déchets aspirés, comprenant un pot de retenue de déchets, des raccords pour conduits d'aspirateur menant à l'intérieur du pot, un filtre présent dans le pot entre un des raccords, affecté à une entrée d'air dans le réservoir, et un autre des raccords, affecté à une sortie d'air du réservoir, caractérisé en ce que le filtre comprend au moins un sac souple, le pot comprend une portion cylindrique dans laquelle coulisse un plateau mobile, repoussé par un ressort vers le sac et séparé du raccord affecté à l'entrée d'air par le sac, et le réservoir comprend encore un dispositif de détection de position du plateau.  In a general form, the invention relates to a vacuum waste container, comprising a waste holding pot, fittings for vacuum ducts leading to the interior of the pot, a filter present in the pot between one of the fittings, affected to an air inlet in the tank, and another of the connections, assigned to an air outlet of the tank, characterized in that the filter comprises at least one flexible bag, the pot comprises a cylindrical portion in which slides a tray mobile, spring biased to the bag and separated from the fitting assigned to the air inlet by the bag, and the reservoir further comprises a tray position detection device.
L'utilisation d'un sac souple en remplacement d'un filtre solide, tel que celui de la figure 2, permet un bon remplissage de l'intérieur du pot, et sans risque de colmatage prématuré. Plus le sac se remplit, plus il repousse le plateau contre l'action du ressort, ce qui est détecté et indique donc finalement quand le remplissage est accompli.  The use of a flexible bag to replace a solid filter, such as that of Figure 2, allows a good filling of the interior of the pot, and without risk of premature clogging. The more the bag fills, the more it pushes the tray against the action of the spring, which is detected and thus finally indicates when the filling is completed.
Le réservoir peut comprendre un embout porteur des raccords, le pot comprend une paroi de fond, une paroi cylindrique et une embouchure du pot opposée au fond, le ressort est comprimé contre le fond, et des moyens d'assemblage du pot sous l'embout étant à une position où l'embouchure est accolée à l'embout. Cela permet de disposer du pot seul à la fin du remplissage, et de remployer l'embout pour une aspiration ultérieure avec un pot de remplacement.  The reservoir may comprise a nozzle carrying the connections, the pot comprises a bottom wall, a cylindrical wall and a mouth of the pot opposite the bottom, the spring is compressed against the bottom, and means for assembling the pot under the endpiece. being at a position where the mouth is contiguous to the mouthpiece. This makes it possible to dispose of the pot alone at the end of filling, and to refill the mouthpiece for subsequent aspiration with a replacement pot.
Le réservoir peut de même comprendre une base, des moyens d'assemblage du pot sur la base, le dispositif de détection de position appartenant alors à la base. Ici encore, le montage et le démontage et donc le remplacement du pot sont faciles, sans que le dispositif de détection doive être remplacé. Il est alors avantageux que le pot comprenne un creux, entouré par le ressort et le plateau, dans lequel le dispositif de détection de position est logé ; et plus encore que le creux soit ouvert, opéré sous le fond du pot, le dispositif de détection de position monté en saillie sur la base, et les moyens d'assemblage du pot sur la base comprennent un centrage du pot par le dispositif de détection, et un support simple du pot par un couvercle supérieur de la base : le pot peut alors être monté sur la base munie des équipements de mesure et de contrôle simplement en le posant sur elle, le détecteur assurant le centrage et le maintien en place du pot. The reservoir may likewise comprise a base, means for assembling the pot on the base, the position detection device then belonging to the base. Here again, the assembly and disassembly and therefore the replacement of the pot are easy, without the detection device must be replaced. It is then advantageous that the pot includes a recess, surrounded by the spring and the tray, wherein the position sensing device is housed; and even more so that the depression is open, operated under the bottom of the pot, the position detection device mounted on the base, and the pot assembly means on the base comprise a centering of the pot by the detection device , and a simple support of the pot by an upper cover of the base: the pot can then be mounted on the base provided with measuring and control equipment simply by placing it on it, the detector ensuring the centering and maintenance in place of pot.
La base comprend encore avantageusement, dans le cas de déchets aspirés radioactifs, un détecteur de radioactivité.  The base still advantageously comprises, in the case of radioactive aspirated waste, a radioactivity detector.
Un montage facile du sac dans le pot est réalisé si celui-ci comprend une bride amovible, porteuse d'un piquage affecté à l'entrée d'air à un état assemblé du réservoir, comprenant, à une première extrémité, une jonction avec le raccord et un support de fixation d'une ouverture du sac souple à une seconde extrémité opposée à la première extrémité.  An easy mounting of the bag in the pot is realized if it comprises a removable flange, carrying a tapping assigned to the air inlet to an assembled state of the tank, comprising, at a first end, a junction with the and a bracket for attaching an opening of the flexible bag to a second end opposite the first end.
Dans un mode de réalisation important, plusieurs sacs sont utilisés à la fois : le piquage est central sur la bride, se divise en plusieurs branches munies chacune d'un support de fixation d'une ouverture d'un dit sac souple respectif, les branches étant réparties autour d'une circonférence du conduit de raccordement.  In one important embodiment, several bags are used at once: the stitching is central on the flange, is divided into several branches each provided with a support for fixing an opening of a said respective flexible bag, the branches being distributed around a circumference of the connecting duct.
Le dispositif peut encore comprendre un couvercle d'encliquetage sur l'embouchure du pot, et qui contribue donc à assurer un confinement fiable et définitif des déchets une fois que le pot est démonté du reste du réservoir.  The device may further comprise a latching cover on the mouth of the pot, and which therefore contributes to ensure a reliable and permanent containment of waste once the pot is removed from the rest of the tank.
Enfin, le pot comprend avantageusement une paroi intérieure perforée séparant un volume restant inoccupé d'un volume d'expansion du sac, afin d'éviter un colmatage prématuré.  Finally, the pot advantageously comprises a perforated inner wall separating a volume remaining unoccupied from an expansion volume of the bag, in order to avoid premature clogging.
Ces aspects de l'invention, ainsi que d'autres, seront maintenant décrits en liaison aux figures suivantes, annexées à titre purement illustratif, qui décrivent une réalisation particulière de l'invention :  These and other aspects of the invention will now be described with reference to the following figures, appended purely for illustrative purposes, which describe a particular embodiment of the invention:
- la figure 1, déjà décrite, représente un schéma d'aspirateur industriel, FIG. 1, already described, represents a diagram of an industrial vacuum cleaner,
- la figure 2, la disposition d'un bidon filtrant, et - les figures 3, 4 et 5, des vues en éclaté des trois principaux éléments d'une réalisation de réservoir, FIG. 2, the arrangement of a filter can, and FIGS. 3, 4 and 5, exploded views of the three main elements of a reservoir embodiment,
- la figure 6 illustre en coupe le réservoir à l'état assemblé,  FIG. 6 illustrates in section the reservoir in the assembled state,
- et la figure 7, un élément d'assemblage du réservoir.  and FIG. 7, an assembly element of the reservoir.
On se reporte à la figure 3.  Referring to Figure 3
La partie du réservoir spécialement associée à l'entreposage des déchets comprend un pot 4 composé principalement d'une enveloppe 5 et d'une bride 6. L'enveloppe 5 comprend une paroi latérale 7 cylindrique, un fond 8, et une embouchure 9 supérieure opposée au fond 8. Une grille 10 cylindrique s'étend à l'intérieur de la paroi latérale 7, à laquelle elle est coaxiale, et sépare un volume annulaire périphérique d'un volume principal du pot 4. La bride 6 comprend un piquage central 11, qui se divise toutefois en branches rayonnantes à l'extrémité inférieure, et les extrémités de ses branches supportent des supports 12 de fixation de sacs 13 souples de filtrage. Quand le pot 4 est assemblé, la bride 6 s'emboîte dans l'embouchure 9 en préservant l'étanchéité, et le piquage central 11 et les sacs 13 sont alors descendus dans le volume central de l'enveloppe 5 entouré par la grille 10.  The portion of the tank specially associated with the storage of waste comprises a pot 4 composed mainly of a casing 5 and a flange 6. The casing 5 comprises a cylindrical side wall 7, a bottom 8, and a mouth 9 superior opposed to the bottom 8. A cylindrical grid 10 extends inside the side wall 7, to which it is coaxial, and separates a peripheral annular volume from a main volume of the pot 4. The flange 6 comprises a central stitching 11, which is however divided into radiating branches at the lower end, and the ends of its branches support supports 12 for fastening 13 flexible filter bags. When the pot 4 is assembled, the flange 6 fits into the mouth 9 while preserving the tightness, and the central stitching 11 and the bags 13 are then lowered into the central volume of the envelope 5 surrounded by the grid 10 .
La figure 3 représente encore un couvercle 14 d'encliquetage sur la bride 6, après le remplissage du pot 4, en préliminaire à son entreposage définitif. Il comprend un rebord périphérique 15 coiffant la bride 6, et des griffes 16 élastique pouvant entrer dans le piquage central 11 et se déployer ensuite en se détendant. Le couvercle 14 reste cependant séparé du réservoir auparavant, et notamment pendant le remplissage.  Figure 3 also shows a latching cover 14 on the flange 6, after the filling of the pot 4, preliminary to its final storage. It comprises a peripheral rim 15 capping the flange 6, and resilient claws 16 that can enter the central tapping 11 and then deploy while relaxing. The lid 14 however remains separated from the tank before, and especially during filling.
La figure 4 représente un embout supérieur, dit caisson d'interface 17, comprenant un raccord 18 de conduit d'entrée, connectable à un conduit d'aspirateur tel que le conduit 41, et un raccord 19 de conduit de sortie tel que le conduit de sortie 42. Le premier est au centre de l'embout 17, le second est excentré. Les raccords 18 et 19 sont munis de sondes de pression 20 et 21, qui indiquent la pression d'air d'aspiration et celle de l'air de refoulement et peuvent annoncer ainsi un risque de colmatage. Le caisson d'interface 17 est un deuxième module principal du réservoir, qu'on assemble avec un emboîtement étanche au pot 4. La figure 5 représente une base 22 qui est le troisième module principal du réservoir. Elle comprend une enveloppe 23, un couvercle supérieur 24 au centre duquel est monté un détecteur de position 25 en saillie, et, dans l'enveloppe 23, un détecteur de radioactivité (pouvant être une sonde de débit de dose 26) monté dans un collimateur 27, et des équipements 28 électriques et électroniques pouvant comprendre des batteries ; l'enveloppe 23 porte aussi des connexions électriques et électroniques 29 et une interface 30 pouvant comprendre des indicateurs d'état de marche, de mesure de capteurs, etc. Le détecteur de position 25 est un détecteur sans contact, magnétique par exemple, monté dans un doigt rigide soudé au couvercle supérieur 24. FIG. 4 represents an upper nozzle, called an interface box 17, comprising an inlet duct connector 18, connectable to a vacuum duct such as the duct 41, and an outlet duct connector 19 such as the duct 42. The first is in the center of the tip 17, the second is eccentric. The connectors 18 and 19 are provided with pressure probes 20 and 21, which indicate the suction air and the discharge air pressure and can thus announce a risk of clogging. The interface box 17 is a second main module of the tank, which is assembled with a sealed engagement with the pot 4. Figure 5 shows a base 22 which is the third main module of the tank. It comprises an envelope 23, an upper cover 24 in the center of which is mounted a protruding position detector 25, and in the envelope 23, a radioactivity detector (which may be a dose rate sensor 26) mounted in a collimator 27, and electrical and electronic equipment 28 which may include batteries; the casing 23 also carries electrical and electronic connections 29 and an interface 30 may include indicators of operating status, measurement of sensors, etc. The position detector 25 is a non-contact, magnetic detector for example, mounted in a rigid finger welded to the top cover 24.
L'intérieur de l'enveloppe 5 du pot 4 comprend encore un plateau 31 mobile, qui s'étend sous les sacs 13 et est aussi entouré par la grille 10. Il est évidé en son centre et traversé par un doigt 32, pointant vers l'intérieur, de l'enveloppe 5, dans lequel un logement s'ouvrant vers le bas est formé.  The inside of the envelope 5 of the pot 4 further comprises a mobile plate 31, which extends under the bags 13 and is also surrounded by the grid 10. It is hollowed at its center and crossed by a finger 32, pointing towards the inside, of the envelope 5, in which a housing opening towards the bottom is formed.
Comme le montre la figure 6, le doigt du détecteur de position 25 pénètre dans ce logement et il l'occupe à l'état de montage du réservoir, ce qui assure le centrage du pot 4 sur la base 22. Le pot 4 est par ailleurs simplement posé sur le couvercle supérieur 24. L'assemblage du caisson d'interface 17 avec le pot 4 peut être réalisé au moyen d'une cage 33 représentée à la figure 7, comprenant un plateau 34 sur lequel le pot 4 est posé par le fond 8, et des colonnettes 35 vissées à leur extrémité chacune au plateau 34 et au caisson d'interface 17. Le plateau 34 est évidé en son centre pour laisser de la place du détecteur de position 25.  As shown in FIG. 6, the finger of the position detector 25 enters this housing and occupies it in the mounting state of the reservoir, which ensures the centering of the pot 4 on the base 22. The pot 4 is by elsewhere simply placed on the upper cover 24. The assembly of the interface box 17 with the pot 4 can be achieved by means of a cage 33 shown in Figure 7, comprising a plate 34 on which the pot 4 is placed by the bottom 8, and columns 35 screwed at their end each to the plate 34 and the interface box 17. The plate 34 is recessed at its center to leave room for the position detector 25.
Un ressort 36 est disposé autour du creux 32 dans l'enveloppe 5. Il est comprimé entre le fond 8 et sur le plateau 31 pour repousser celui-ci vers le haut. Le raccord 18 traverse complètement le caisson d'interface 17 et s'abouche au piquage central 11, alors que le caisson d'interface 17, dont le fond est évidé, communique avec l'intérieur du pot 4. L'étanchéité du volume ainsi constitué est assurée par des joints d'étanchéité 37 et 38 disposés sur la face supérieure et la face périphérique de la bride 11 et comprimés respectivement par le fond du caisson d'interface 17 et le sommet de la paroi latérale 7. Quand l'aspiration est entreprise, les déchets sont aspirés dans les sacs 13 et y demeurent, alors que l'air les traverse et revient au caisson d'interface 17, avant d'être refoulé dans le raccord 19 de sortie ; il dispose toujours du volume périphérique, au-delà de la grille 10, quel que soit le gonflement des sacs 13, pour s'écouler sans colmatage précoce, avant le remplissage complet des sacs 13. Quand le remplissage augmente, les déchets aspirés pèsent sur le plateau 31 et le font descendre progressivement. Le détecteur de position 25, qui est à hauteur du plateau 31, pendant toute sa course de descente, mesure à tout instant la position de hauteur du plateau 31 par une variation d'interaction magnétique et indique notamment quand le plateau 31 et à son niveau le plus bas, qui signifie que le pot 4 est plein. Un arrêt de l'aspiration plus précoce peut toutefois être décidé si par exemple la sonde de débit de dose 26 indique qu'un niveau excessif de radioactivité va être atteint. Les détecteurs de pression 20 et 21 sont également suivis. Les résultats peuvent être affichés sur l'interface 30 ou transmis à distance. A spring 36 is disposed around the recess 32 in the casing 5. It is compressed between the bottom 8 and the plate 31 to push it upwards. The connector 18 completely crosses the interface box 17 and engages the central branching 11, while the interface box 17, whose bottom is recessed, communicates with the interior of the pot 4. The sealing of the volume and formed is provided by seals 37 and 38 disposed on the upper face and the peripheral face of the flange 11 and respectively compressed by the bottom of the interface box 17 and the top of the side wall 7. When the suction is undertaken, the waste is sucked into the bags 13 and remain there, while the air passes through and returns to the interface box 17, before being discharged into the outlet 19; it always has the peripheral volume, beyond the grid 10, regardless of the swelling of the bags 13, to flow without clogging early, before the full filling of the bags 13. When the filling increases, the waste aspired weighs on the plate 31 and make it descend gradually. The position detector 25, which is at the height of the plate 31, during its entire downstroke, measures at any instant the height position of the plate 31 by a magnetic interaction variation and indicates in particular when the plate 31 and at its level the lowest, which means that pot 4 is full. An earlier termination of aspiration may however be decided if for example the dose rate probe 26 indicates that an excessive level of radioactivity will be reached. The pressure sensors 20 and 21 are also tracked. The results can be displayed on the interface 30 or transmitted remotely.
Quand le remplissage est accompli, le réservoir est isolé du reste de l'aspirateur en démontant les conduits 4 et 5, puis les vis supérieures des colonnettes 35 sont enlevées, le caisson d'interface 17 est soulevé ; et (en procédant alors avantageusement par télémanipulation pour cette partie du démontage la plus dangereuse, les déchets étant alors immédiatement accessibles), le couvercle 14 est placé sur la bride 6, et le pot 4 est soulevé et emporté. On peut alors disposer du pot 4 sans risquer de verser son contenu. Un pot 4 neuf est préparé et le réservoir est de nouveau assemblé.  When the filling is completed, the tank is isolated from the rest of the vacuum by dismounting the conduits 4 and 5, then the upper screws of the columns 35 are removed, the interface box 17 is raised; and (by then proceeding advantageously by remote handling for this part of the most dangerous disassembly, the waste being then immediately accessible), the cover 14 is placed on the flange 6, and the pot 4 is lifted and carried away. We can then dispose of the pot 4 without risking its content. A new pot 4 is prepared and the tank is assembled again.
