Abstract

The packaging has a first exterior bag (2A) which receives a second bag (2B) which is air permeable. The external bag can be folded on itself to sealingly enclose the inner bag. The packaging machine has a casing (3) of a size sufficient to receive the bags and has an opening (4) for communication with the exterior of the casing and having a mouth to which the bag is connected and a supply pipe for the waste. One of the walls of the casing has a pair of sealed gloves for handling the waste which is conveyed by suction.

Description

L'invention se rapporte à un dispositif pour le conditionnement de déchets, tels l'amiante. The invention relates to a device for packaging waste, such as asbestos.

Pour retarder les effets produits sur les structures de bâtiment lors d'incendie, ces structures sont généralement recouvertes d'un enduit contenant une forte proportion de fibres d'amiante. To delay the effects produced on building structures during fire, these structures are generally covered with a coating containing a high proportion of asbestos fibers.

Ces fibres d'amiante présentant un degré de toxicité non négligeable, il est devenu nécessaire d'éliminer la couche d'enduit contenant les dites fibres. These asbestos fibers having a non-negligible degree of toxicity, it has become necessary to eliminate the coating layer containing the said fibers.

En raison de leur toxicité, cette opération doit se réaliser dans un milieu confiné et les déchets doivent être transportés dans des conditions de sécurité maximale. Due to their toxicity, this operation must be carried out in a confined environment and the waste must be transported under conditions of maximum safety.

Pour procéder à cette opération, à l'aide de feuilles en matériau plastique, on isole hermétiquement le secteur du bâtiment à nettoyer. To carry out this operation, using plastic sheets, the area of the building to be cleaned is hermetically sealed.

Ce secteur est placé en légère dépression pour éviter que les poussières et fibres se disséminent partout et les opérateurs revêtus de tenue étanche décollent l'enduit puis ramassent, à l'aide de pelles ou d'instruments similaires, l'enduit tombé sur le sol et le placent dans des sacs qu'ils ferment alors hermétiquement. This sector is placed in a slight depression to prevent dust and fibers from spreading everywhere and operators wearing waterproof clothing peel off the plaster then collect, using shovels or similar instruments, the plaster that has fallen on the ground and place it in bags which they then seal tightly.

Ces sacs remplis doivent ensuite être lavés extérieurement avant de sortir de la zone confinée. These filled bags must then be washed externally before leaving the confined area.

A ce jour, le lavage est réalisé de manière très rudimentaire et sans réelle garantie. To date, washing is carried out in a very rudimentary way and without any real guarantee.

Cette opération d'élimination de l'amiante est extrêmement longue fastidieuse et pénible en raison notamment de la quantité de poussière générée lors des multiples manipulations. This asbestos removal operation is extremely long, tedious and painful due in particular to the amount of dust generated during multiple handling operations.

Pour l'élimination de l'amiante entourant les tubes de chauffage, on connaît un sac (EP-A-0.375.104) dont la paroi comporte deux gants pénétrant à l'intérieur du sac. For the removal of asbestos surrounding the heating tubes, a bag (EP-A-0.375.104) is known, the wall of which comprises two gloves penetrating inside the bag.

L'ouverture du sac présente des rabats permettant de ceindre le tube encore recouvert d'amiante et de l'isoler de l'extérieur. The opening of the bag has flaps allowing to girdle the tube still covered with asbestos and to isolate it from the outside.

L'opérateur peut, en introduisant ses bras dans les gants précités, depuis l'intérieur du sac, faire tomber l'amiante à l'intérieur du sac.  The operator can, by inserting his arms into the aforementioned gloves, from inside the bag, cause the asbestos to fall inside the bag.

Un tel dispositif n'est utilisable que pour certains travaux et si l'opérateur doit intervenir avec un outil, il risque de porter atteinte accidentellement à l'intégrité du sac. Such a device can only be used for certain works and if the operator must intervene with a tool, it risks accidentally damaging the integrity of the bag.

Un des résultats que l'invention vise à obtenir est notamment de faciliter et de sécuriser le conditionnement des déchets, tels l'amiante. One of the results that the invention aims to obtain is in particular to facilitate and secure the packaging of waste, such as asbestos.

A cet effet, l'invention a pour objet un dispositif du type précité comprenant un sac dans lequel sont introduits les déchets, ce dispositif étant caractérisé en ce que le sac est constitué d'un premier sac, dit sac externe, étanche logeant un deuxième sac, dit interne, perméable à l'air, le sac externe étant repliable sur lui-même pour n'envelopper le sac interne que lorsque celui-ci est rempli. To this end, the subject of the invention is a device of the aforementioned type comprising a bag into which the waste is introduced, this device being characterized in that the bag consists of a first bag, called an external, waterproof bag accommodating a second bag, said internal, breathable, the external bag being foldable on itself so as not to wrap the internal bag until it is full.

L'invention sera bien comprise à l'aide de la description ci-après faites à titre d'exemple non limitatif et en regard du dessin qui représente
- figure 1 : un dispositif selon l'invention,
- figure 2 : une vue de la figure 1 selon F.The invention will be clearly understood with the aid of the description below made by way of nonlimiting example and with reference to the drawing which represents
FIG. 1: a device according to the invention,
- Figure 2: a view of Figure 1 along F.

En se reportant au dessin, on voit que, pour éliminer des déchets, tels de l'amiante recouvrant la structure d'un bâtiment, on utilise un dispositif 1 pour le conditionnement de déchets comprenant au moins un sac 2 dans lequel sont introduits les déchets. Referring to the drawing, it can be seen that, to eliminate waste, such as asbestos covering the structure of a building, a device 1 is used for packaging waste comprising at least one bag 2 into which the waste is introduced. .

Classiquement, pour retirer l'amiante, la zone de travail est isolée par des feuilles plastiques et cette zone de travail n'est accessible qu'au travers d'un sas. Conventionally, to remove the asbestos, the work area is isolated by plastic sheets and this work area is only accessible through an airlock.

Selon une caractéristique de l'invention
- le sac 2 est constitué d'un premier sac 2A, dit sac externe, étanche logeant un deuxième sac 2B, dit interne, perméable à l'air, le sac externe étant repliable sur lui-même pour n'envelopper le sac interne que lorsque celui-ci est rempli et,
- le dispositif comprend en outre
un caisson 3 de taille suffisante pour y loger les sacs 2A, 2B, ce caisson présentant un orifice 4 de communication avec l'extérieur du caisson comportant, quant à lui, d'une part, un moyen 5 de raccordement avec la bouche 6 du sac interne 2B et, d'autre part, à l'extérieur du caisson, un tuyau 7 par lequel les déchets sont dirigés vers l'intérieur du sac,
un dispositif 8 d'aspiration générant, dans le caisson, une dépression produisant au travers du sac interne un débit d'air dans le tuyau suffisamment important pour véhiculer les déchets aspirés à l'extrémité libre du tuyau et
l'une des parois du caisson 3 présente une paire de gants 9 pénétrant à l'intérieur du caisson et permettant depuis l'extérieur dudit caisson la manipulation des sacs.According to a characteristic of the invention
the bag 2 is made up of a first bag 2A, called an external, waterproof bag housing a second bag 2B, said to be internal, permeable to air, the external bag being foldable over itself so as to only wrap the internal bag when it is filled and,
- the device further comprises
a box 3 of sufficient size to accommodate the bags 2A, 2B, this box having an orifice 4 for communication with the outside of the box comprising, for its part, on the one hand, a means 5 for connection with the mouth 6 of the internal bag 2B and, on the other hand, outside the box, a pipe 7 by which the waste is directed towards the interior of the bag,
a suction device 8 generating, in the box, a vacuum producing through the internal bag an air flow in the pipe large enough to convey the waste sucked to the free end of the pipe and
one of the walls of the box 3 has a pair of gloves 9 penetrating inside the box and allowing from the outside of said box the handling of the bags.

Pour cette manipulation, au moins localement l'une des parois de ce caisson 3 est transparente. For this manipulation, at least locally one of the walls of this box 3 is transparent.

Egalement, le caisson 3 présente une porte pour accéder aux sacs. Also, the box 3 has a door for accessing the bags.

Le dispositif comprend un filtre 10 intercalé entre le volume interne du caisson et le dispositif 8 d'aspiration. The device comprises a filter 10 interposed between the internal volume of the box and the suction device 8.

Ce filtre 10 est échangeable. Il est dit à filtration absolue. This filter 10 is exchangeable. It is said to be absolute filtration.

La taille de la maille de filtration est de l'ordre de cinq microns. The size of the filtration mesh is of the order of five microns.

L'ordre de l'échange de ce filtre, il est placé dans un sac 20 qui est soudé ensuite pour le fermer. The order of the exchange of this filter, it is placed in a bag 20 which is then welded to close it.

Avantageusement
- d'une part, le caisson 3 loge un dispositif 11 de projection d'eau permettant de laver le sac externe 2A lorsque celui-ci est refermé autour du sac interne 2B et,
- d'autre part, la base du caisson présente un moyen 12 pour recueillir les eaux de lavage, tel un bac 12.Advantageously
on the one hand, the box 3 houses a device 11 for spraying water making it possible to wash the external bag 2A when the latter is closed around the internal bag 2B and,
- on the other hand, the base of the box has a means 12 for collecting the washing water, such as a tank 12.

L'évacuation de l'eau se fait également au travers d'un élément de filtrage. The water is also evacuated through a filter element.

Des moyens 13 de protection évitent le contact entre le filtre 10 du dispositif d'aspiration et les projections d'eau lors du lavage. Protection means 13 prevent contact between the filter 10 of the suction device and water splashes during washing.

Pour permettre l'échange sans risque du sac, des robinets 14 d'isolement permettent
- d'interrompre la circulation sur le tuyau,
- la conduite d'évacuation de l'eau de lavage et,
- a conduite reliant le caisson au dispositif d'aspiration. To allow safe exchange of the bag, isolation valves 14 allow
- to interrupt circulation on the pipe,
- the washing water discharge line and,
- a pipe connecting the box to the suction device.

Nnotamment dans le cas de chantiers importants, on prévoit un dispositif d'aspiration alimentant plusieurs caissons regroupés sur une structure porteuse pouvant être saisie par un engin de manutention. In particular in the case of large sites, a suction device is provided supplying several boxes grouped together on a carrying structure which can be gripped by a handling machine.

Chaque caisson comporte son propre bac d'écoulement. Each box has its own drain pan.

Le transfert des déchets s'opère avec toute la sécurité nécessaire car il n'y plus de risques de contact. The transfer of waste is carried out with all the necessary security because there is no longer any risk of contact.

Il est possible de prévoir des automatismes (non représentés) interdisant toutes fausses manoeuvres, telles l'ouverture du caisson, pour extraire le sac avant que l'opération de lavage ne soit réalisée. It is possible to provide automatic devices (not shown) prohibiting any false maneuvers, such as opening the box, to extract the bag before the washing operation is carried out.

Un avantage d'un tel dispositif résulte également de l'aspiration produite dans le tuyau véhiculant les déchets et qui contribue au maintien en dépression de la zone de travail isolée.  An advantage of such a device also results from the suction produced in the pipe conveying the waste and which contributes to maintaining the vacuum in the isolated working area.
