DISPOSITIF D'ASPIRATION ET DE STOCKAGE DE RESIDUS ET CARTOUCHE DE FILTRATION CORRESPONDANTE RESIDUE SUCTION AND STORAGE DEVICE AND CORRESPONDING FILTRATION CARTRIDGE

La présente invention concerne un dispositif pour aspirer et stocker avant et pendant leur refroidissement des résidus de combustion de bois, de charbon (ou de leurs dérivés). Ces résidus proviennent de combustions réalisées dans divers appareils de chauffage et/ou de cuisson. La présente invention vise plus particulièrement à réduire au maximum les risques de brûlures ou de dégagement de poussières pendant ces opérations d'aspiration et de stockage.The present invention relates to a device for aspirating and storing, before and during their cooling, combustion residues of wood, charcoal (or their derivatives). These residues come from combustions carried out in various heating and / or cooking appliances. The present invention aims more particularly to minimize the risk of burns or dust generation during these suction and storage operations.

La co l l e c te d e c e s ré s i du s , traditionnellement à l'aide de pelles, balais et seaux, génère des poussières et présente des risques de brûlures lors de l'accès aux recoins dans lesquels ils sont logés. En outre, il se pose souvent le problème de la conservation de ces résidus jusqu'à leur complet refroidissement. Le dispositif selon l'invention permet de pallier ces divers inconvénients.The co l e c te d e c e s re s i of s, traditionally using shovels, brooms and buckets, generates dust and poses the risk of burns when accessing the recesses in which they are housed. In addition, there is often the problem of preserving these residues until they have completely cooled. The device according to the invention overcomes these various drawbacks.

A cet effet, la présente invention concerne un dispositif d'aspiration et de stockage de résidus du type comportant une cuve de stockage à double paroi, adaptée pour contenir lesdits résidus, ladite cuve étant munie d'un tuyau d'aspiration adapté pour introduire les résidus dans la cuve et d'un tuyau d'évacuation hors de la cuve, de l'air aspiré avec ces résidus, ledit dispositif étant caractérisé en ce qu'il comporte, en amont du tuyau d'évacuation, une cartouche de filtration munie d'une pluralité de filtres ; une première unité de filtre étant munie d'un moyen de décolmatage adapté pour gratter la totalité de la paroi de la première unité de filtre et pour entraîner vers le bas les résidus ainsi décollés. La présente invention concerne également une cartouche de filtration correspondante.To this end, the present invention relates to a device for suction and storage of residues of the type comprising a double-walled storage tank, adapted to contain said residues, said tank being provided with a suction pipe suitable for introducing the residues in the tank and of an evacuation pipe outside the tank, of the air sucked up with these residues, said device being characterized in that it comprises, upstream of the evacuation pipe, a filtration cartridge provided a plurality of filters; a first filter unit being provided with an unclogging means suitable for scraping the entire wall of the first filter unit and for driving down the residues thus detached. The present invention also relates to a corresponding filter cartridge.

D'autres objets, caracté istiques et avantages de la présente invention ressortiront d'ailleurs de la description qui va suivre en référence aux dessins annexés, dans lesquels :Other objects, characteristics and advantages of the present invention will emerge from the description which follows with reference to the appended drawings, in which:

- la figure 1 est une vue en coupe verticale d'un dispositif d'aspiration et de stockage selon la présente invention, - la figure 2 est une vue en coupe selon la ligne II II de la figure 1.- Figure 1 is a vertical sectional view of a suction and storage device according to the present invention, - Figure 2 is a sectional view along line II II of Figure 1.

- la figure 3 est une vue en perspective, partiellement arrachée, montrant la brosse rotative selon l'invention et son action sur la première unité de filtre 24.FIG. 3 is a perspective view, partially cut away, showing the rotary brush according to the invention and its action on the first filter unit 24.

Le dispositif 10 selon l'invention est un aspirateur vertical de type bidon, composé notamment d'une cuve de stockage 11 de sécurité et d'un couvercle 12 surmonté de l'appareillage électrique 13 nécessaire à son fonctionnement.The device 10 according to the invention is a vertical canister type vacuum cleaner, composed in particular of a safety storage tank 11 and a cover 12 surmounted by the electrical equipment 13 necessary for its operation.

Tous les éléments au contact direct des cendres 14 (ou résidus chauds) sont métalliques ou minéraux et ininflammables.All the elements in direct contact with the ashes 14 (or hot residues) are metallic or mineral and non-flammable.

La cuve de stockage 11 est à double paroi 11a, 11b, y compris le fond 15. La paroi interne 11a peut constituer un récipient amovible et est recouverte à l'extérieur de matériau isolant 16. Une lame d'air 17 la sépare de l'enveloppe externe 11b, qui est ajourée au moins sur une partie de son pourtour par des ouvertures de ventilation 18, de sorte qu'une circulation d'air (flèches F) s'établisse, de manière naturelle, entre les parois interne 11a et externe 11b et permette le refroidissement des cendres 14 contenues dans la cuve 11.The storage tank 11 has a double wall 11a, 11b, including the bottom 15. The internal wall 11a can constitute a removable container and is covered on the outside with insulating material 16. An air space 17 separates it from the external envelope 11b, which is perforated at least over part of its periphery by ventilation openings 18, so that an air circulation (arrows F) is established, naturally, between the internal walls 11a and 11b and allows the ashes 14 contained in the tank 11 to be cooled.

Lors de la mise en marche du dispositif selon l'invention, les cendres 14 ou résidus chauds sont aspirés par un tuyau d'aspiration 19, pour être envoyés vers la cuve de stockage 11. Lors de l'aspiration des cendres ou résidus, une partie de l'air ambiant est entraîné avec les cendres. Cet air, une fois dans la cuveWhen the device according to the invention is started up, the ashes 14 or hot residues are sucked up by a suction pipe 19, to be sent to the storage tank 11. During the aspiration of the ashes or residues, a part of the ambient air is entrained with the ashes. This air, once in the tank

REMPLACEMENT DE de stockage 11, est aspiré vers la turbine d'aspiration T placée au-dessus du couvercle 12, avec tout l'appareillage électrique 13. Cependant, cet air est chargé de cendres volantes parfois encore rougeoyantes. C'est pourquoi, l'utilisation d'un aspirateur normal pour l'aspiration de résidus chauds entraîne aussitôt l'incendie des filtres habituels, en papier ou en tissu. En outre, la présence d'air ambiant avec ces cendres a tendance à ranimer les cendres et à favoriser leur combustion.REPLACEMENT OF storage 11, is sucked towards the suction turbine T placed above the cover 12, with all the electrical equipment 13. However, this air is charged with fly ash sometimes still glowing. This is why the use of a normal vacuum cleaner for the suction of hot residues immediately causes the fire of the usual filters, in paper or fabric. In addition, the presence of ambient air with these ashes tends to revive the ashes and promote their combustion.

Pour éviter ceci, dans le dispositif selon l'invention, on a installé en amont de la turbine d'aspiration T une cartouche filtrante 20 anti-feu amovible, démontable, nettoyable et résistante à la chaleur. Cette cartouche comporte à l'intérieur d'un carter 21 trois unités de filtres cylindriques 22, 23, 24 disposées concentriquement et chacune amovible :To avoid this, in the device according to the invention, a removable, removable, cleanable and heat-resistant fire filter cartridge 20 has been installed upstream of the suction turbine T. This cartridge has inside a casing 21 three cylindrical filter units 22, 23, 24 arranged concentrically and each removable:

- le cylindre extérieur 22 ou troisième unité de filtre, est tapissé de laine minérale, de substituts d'amiante ou autres, et est poreux afin de retenir les particules micronisées échappées des deux premières unités de filtres 23, 24,the outer cylinder 22 or third filter unit is lined with mineral wool, asbestos substitutes or the like, and is porous in order to retain the micronized particles escaped from the first two filter units 23, 24,

- le cylindre médian 23 ou seconde unité de filtre est garni de laine d'acier inoxydable et stoppe les poussières les plus grosses non retenues par la première unité de filtre 24,the middle cylinder 23 or second filter unit is lined with stainless steel wool and stops the coarsest dust not retained by the first filter unit 24,

- le cylindre interne 24 ou première unité de filtre fait fonction de filtre primaire et est constitué d'un cylindre creux rigide (figure 3), perforé d'une multitude de trous microscopiques 25. C'est cette unité qui arrête la quasi totalité des cendres volantes entraînées avec l'air d'aspiration. Il est à noter que l'aspiration de l'air par le tuyau 19 oblige celui-ci à passer dans la cuve 11, puis successivement par les première, deuxième et troisième unité de filtre 24, 23, 22, avant d'être amené vers un conduit 40 d'amenée d'air à une turbine d'aspiration T.the internal cylinder 24 or first filter unit acts as a primary filter and consists of a rigid hollow cylinder (FIG. 3), perforated with a multitude of microscopic holes 25. It is this unit which stops almost all of the fly ash entrained with suction air. It should be noted that the aspiration of air by the pipe 19 obliges the latter to pass into the tank 11, then successively through the first, second and third filter unit 24, 23, 22, before being brought in. towards a duct 40 for supplying air to a suction turbine T.

La première unité de filtre est avantageusement munie d'un moyen de décolmatage réalisé par une brosse rotative 26 tri-pales. Cette brosse 26 est entraînée en rotation autour d'un axe A situé au centre de la première unité de filtre 24. L'axe A traverse le couvercle 12 et est entraîné par tout moyen approprié, par exemple par un moteur faisant partie de l'appareillage électrique 13-The first filter unit is advantageously provided with an unclogging means produced by a rotary brush 26 tri-blades. This brush 26 is rotated about an axis A located in the center of the first filter unit 24. The axis A passes through the cover 12 and is driven by any suitable means, for example by a motor forming part of the electrical equipment 13-

Chacune des pales 27 (figures 2 et 3) de la brosse est inclinée d'un angle «--•. (figure 3) par rapport à la verticale, afin de ramener vers le bas toute particule de cendre décollée de la paroi de la première unité de filtre 24 par la rotation de la brosse. L'extrémité libre de chacune des pales frotte (gratte) en effet contre la paroi de la première unité de filtre 24 et empêche le colmatage des perforations 25 de celle-ci (ou au moins le retarde considérablement). Il est à noter que l'inclinaison des pales 27 vers le bas favorise la création d'un léger remous au niveau de la première unité de filtre 24 et améliore encore la redescente par gravité des cendres volantes vers le fond de la cuve. Le moyen d'entraînement de l'axe A peut être actionné à l'aide d'une simple poignée (donc manuellement) ou électriquement grâce à un petit moteur muni d'un réducteur de vitesse. Il est à noter que les pales 27 sont ré ulièrement réparties autour de l'axe A.Each of the blades 27 (Figures 2 and 3) of the brush is inclined at an angle "- • . (Figure 3) relative to the vertical, in order to bring down any particle of ash detached from the wall of the first filter unit 24 by the rotation of the brush. The free end of each of the blades rubs (scrapes) in effect against the wall of the first filter unit 24 and prevents clogging of the perforations 25 thereof (or at least considerably delays it). It should be noted that the inclination of the blades 27 downwards promotes the creation of a slight eddy at the level of the first filter unit 24 and further improves the descent by gravity of the fly ash towards the bottom of the tank. The axis A drive means can be operated with a simple handle (therefore manually) or electrically with a small motor fitted with a speed reducer. It should be noted that the blades 27 are distributed approximately around the axis A.

La face interne du couvercle 12 est tapissée d'un matériau 30 isolant thermique mais aussi phonique. L'appareillage électrique 13 (turbine d'aspiration et/ou moteur d'entraînement de la brosse) est fixé sur le couvercle 12, sur une semelle isolante (non représentée), de façon surélevée pour constituer une lame d'air isolante entre le couvercle et ces appareils électriques.The inner face of the cover 12 is lined with a thermal insulating material but also a sound insulator. The electrical equipment 13 (suction turbine and / or brush drive motor) is fixed on the cover 12, on an insulating soleplate (not shown), in a raised manner to form an insulating air gap between the cover and these electrical appliances.

La turbine d'aspiration T (représentée schematiquement) pourrait néanmoins être endommagée lors de l'aspiration de cendres ou résidus très chauds. Pour pallier cet inconvénient, une admission d'air ambiant B est prévue entre le circuit d'aspiration et l'entrée de cette turbine, afin d'abaisser la température du flux d'airThe suction turbine T (shown diagrammatically) could nevertheless be damaged when aspirating very hot ashes or residues. To overcome this drawback, an ambient air intake B is provided between the suction circuit and the inlet of this turbine, in order to lower the temperature of the air flow.

FEUILLE DE REMPLACEMENT arrivant par ce circuit. A cet effet, un orifice 31, pratiqué sur le tuyau de sortie 40 de la cuve 11, est obturé par un ressort bi-lame 41 à dilatation rapide formant clapet. La dilatation de ce ressort l'écarté de l'orifice et permet ainsi l'arrivée d'air ambiant B extérieur (figure 1).REPLACEMENT SHEET arriving by this circuit. To this end, an orifice 31, formed on the outlet pipe 40 of the tank 11, is closed by a bi-leaf spring 41 with rapid expansion forming a valve. The expansion of this spring away from the orifice and thus allows the arrival of ambient air B outside (Figure 1).

L'abaissement de température ainsi réalisé, avant l'introduction de l'air dans la turbine T, permet alors de prévoir une ultime filtration de l'air aspiré, après son passage dans la turbine et avant son rejet à l'extérieur de l'aspirateur. Par exemple, un système classique (non représenté) de sacs de papier et tissu -ou mieux, en matériaux minéraux ou autres résistants au feu- est prévu. Le dispositif selon l'invention est particulièrement destiné au nettoyage des cheminées à foyer ouvert ou fermé, poêles, cuisinières, brûlant du bois, du charbon ou leurs dérivés. Il peut bien sûr être utilisé comme un aspirateur classique et aspirer de l'eau. II est à noter que, de manière avantageuse, la cartouche filtrante 20 est contenue dans un carter 21 mis en place par encliquetage dans le couvercle 12 de la cuve. Ainsi, il est possible de changer facilement et complètement la cartouche filtrante et de la remplacer par une cartouche neuve.The temperature reduction thus achieved, before the introduction of air into the turbine T, then makes it possible to provide for a final filtration of the air sucked in, after it has passed through the turbine and before it is discharged outside the 'vacuum. For example, a conventional system (not shown) of paper and fabric bags - or better, in mineral or other fire resistant materials - is provided. The device according to the invention is particularly intended for cleaning open or closed hearth fireplaces, stoves, stoves, burning wood, coal or their derivatives. It can of course be used like a conventional vacuum cleaner and suck up water. It should be noted that, advantageously, the filter cartridge 20 is contained in a casing 21 put in place by snap-fastening in the cover 12 of the tank. Thus, it is possible to easily and completely change the filter cartridge and replace it with a new cartridge.

De même, le carter 21 de cette cartouche filtrante peut être démonté (par simple encliquetage 50) pour permettre l'accès aux trois unités de filtres 24, 23, 22 et leur démontage pour nettoyage par tout moyen approprié.Similarly, the casing 21 of this filter cartridge can be removed (by simple snap-fastening 50) to allow access to the three filter units 24, 23, 22 and their removal for cleaning by any suitable means.

Bien sûr, la présente invention n'est pas limitée au mode de réalisation décrit et englobe toute variante à la portée de l'homme de l'art. Ainsi, en faisant varier les dimensions des composants, le dispositif peut également servir au déblaiement de gravats pulvérulents non chauds, tels que des sciures, plâtres, etc. Of course, the present invention is not limited to the embodiment described and encompasses any variant within the reach of ordinary skill in the art. Thus, by varying the dimensions of the components, the device can also be used for clearing non-hot powdery rubble, such as sawdust, plaster, etc.
