Description
L'invention concerne une structure de filtre pour des conditionneurs d'air du type industriel, ces conditionneurs étant utilisés pour conditionner l'air vicié par des vapeurs telles que des vapeurs de kérosène, par exemple, dans les aéroports, ou des vapeurs de solvant.The invention relates to a filter structure for air conditioners of the industrial type, these conditioners being used for conditioning stale air by vapors such as kerosene vapors, for example, in airports, or solvent vapors. .
Des filtres de ce type sont connus (voir par exemple BE-A-845 165) et sont constitués de panneaux comportant une embase sur laquelle font saillie des pavés de forme parallélépipèdique et contenant un élément actif, tel que du charbon actif. En général, un grand nombre de panneaux est monté sur un châssis pour présenter une structure en accordéon, chaque panneau de filtre étant monté, de chaque côté, entre des éléments en forme de peigne. Des plaques latérales sont montées de part et d'autre de la structure.Filters of this type are known (see for example BE-A-845 165) and consist of panels comprising a base on which protrude blocks of parallelepiped shape and containing an active element, such as activated carbon. In general, a large number of panels are mounted on a frame to present an accordion structure, each filter panel being mounted, on each side, between comb-shaped elements. Side plates are mounted on either side of the structure.
L'inconvénient majeur de cette structure d'assemblage réside dans le fait que, vu le nombre important de panneaux que comportent ces filtres, la structure en accordéon est longue et difficile à assembler et à démonter. Une fois les panneaux usés, leur changement n'est pas valablement envisageable, si bien que c'est l'ensemble du filtre avec ses panneaux et du châssis qui doit être changé. L'opération est donc particulièrement coûteuse.The major drawback of this assembly structure lies in the fact that, given the large number of panels that these filters include, the accordion structure is long and difficult to assemble and disassemble. Once the panels are worn, their change is not validly possible, so that it is the entire filter with its panels and the chassis which must be changed. The operation is therefore particularly expensive.
Le but de l'invention est donc de proposer une structure de filtre qui permette un assemblage simple des panneaux sur le châssis et un démontage aisé si bien qu'il devient intéressant de les changer tout en gardant le même châssis.The object of the invention is therefore to propose a filter structure which allows simple assembly of the panels on the chassis. and easy disassembly so that it becomes interesting to change them while keeping the same chassis.
A cet effet, l'invention concerne une structure de filtre du type pour conditionneur d'air industriel comprenant un châssis et une pluralité de panneaux de filtre constitués de caissons contenant un produit actif, tel que du charbon actif, et montés en accordéon sur le châssis.To this end, the invention relates to a filter structure of the type for industrial air conditioner comprising a frame and a plurality of filter panels consisting of boxes containing an active product, such as activated carbon, and mounted in accordion on the frame.
Selon l'invention, ledit châssis est constitué de deux plaques latérales et les panneaux sont montés par couple sur lesdites plaques, les panneaux d'un couple comportant une même embase présentant, à chacune de ses extrémités, une gaine cylindrique transversale à l'intérieur de laquelle est enfilée une tige, une autre tige étant montée à l'intérieur de l'angle formé par une zone d'articulation de l'embase entre les deux panneaux d'un même couple, les deux extrémités des tiges enfilées dans les gaines des embases de la structure étant, respectivement, montées, de manière coulissante, dans les fonds de deux glissières fixées, chacune, sur une plaque latérale et constituées d'un profilé en forme de "U", lesdits fonds des glissières se faisant face, et les deux extrémités des tiges enfilées dans l'angle des zones d'articulation des embases de la structure étant respectivement montées dans des trous percés dans chacune des plaques latérales.According to the invention, said chassis consists of two side plates and the panels are mounted in pairs on said plates, the panels of a couple comprising the same base having, at each of its ends, a transverse cylindrical sheath inside from which a rod is threaded, another rod being mounted inside the angle formed by an articulation zone of the base between the two panels of the same pair, the two ends of the rods threaded in the sheaths bases of the structure being, respectively, mounted, in a sliding manner, in the bottoms of two slides, each fixed on a side plate and made up of a "U" shaped profile, said bottoms of the slides facing each other, and the two ends of the rods threaded in the corner of the articulation zones of the bases of the structure being respectively mounted in holes drilled in each of the side plates.
Selon une autre caractéristique de l'invention, les trous d'une même plaque sont, d'une part, alignés selon une droite parallèle à la longueur de la glissière fixée sur la même plaque et distante de cette glissière d'une longueur inférieure à la longueur d'un panneau de filtre, et, d'autre part, deux à deux équidistants, un trou d'une plaque correspond à un trou de l'autre plaque de manière que leur axe commun soit perpendiculaire à chacun des plans formés par les plaques latérales.According to another characteristic of the invention, the holes in the same plate are, on the one hand, aligned along a straight line parallel to the length of the slide fixed on the same plate and distant from this slide by a length less than the length of a filter panel, and, on the other hand, two to two equidistant, a hole in one plate corresponds to a hole in the other plate so that their common axis is perpendicular to each of the planes formed by the side plates.
Selon une autre caractéristique de l'invention, les glissières peuvent être déplacées pour ajuster la distance qui les sépare de la droite d'alignement des trous des plaques latérales.According to another characteristic of the invention, the slides can be moved to adjust the distance between them and the straight line of alignment of the holes in the side plates.
Selon une autre caractéristique de l'invention, l'embase est formée de deux embases, une sous chaque panneau d'un couple, reliées entre elles par des moyens qui forment la zone d'articulation.According to another characteristic of the invention, the base is formed of two bases, one under each panel of a pair, connected together by means which form the articulation zone.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec le dessin joint dont la Fig. unique est une vue en perspective d'une structure de filtre selon l'invention, cette structure étant démontée et un élément du premier plan ayant été retiré pour ne pas l'alourdir.The characteristics of the invention mentioned above, as well as others, will appear on reading the following description of an exemplary embodiment, said description being made in relation to the attached drawing, of which FIG. a single is a perspective view of a filter structure according to the invention, this structure being dismantled and an element of the foreground having been removed so as not to weigh it down.
La structure de filtre représentée à la Fig. se compose de deux couples 1, 2 de panneaux montés en accordéon et de plaques latérales 3 (seule celle d'arrière plan étant représentée) formant un châssis. L'invention s'applique également aux structures de filtres composées d'une pluralité de couples de panneaux dont le nombre est supérieur à deux et, notamment, aux structures à seize couples de panneaux.The filter structure shown in FIG. consists of two
Chaque couple 1, 2 de panneaux comprend deux panneaux 4, 5 montés sur une même embase 6. Chaque panneau 4, 5 est constitué de charbon actif contenu dans un caisson présentant une forme sensiblement parallélépipèdique. Ce caisson peut aussi être constitué d'une pluralité de pavés parallélépipèdiques disposés en damier sur l'embase.Each
A chaque extrémité de l'embase 6 d'un couple 1, 2 de panneaux, est formée, dans l'embase 6 elle-même, des gaines cylindriques 7, 8 transversales.At each end of the
Sur chacune des plaques latérales 3, est fixée une glissière 9 constituée d'un profilé en forme de "U". Les fonds des "U" des deux glissières 9 sont en regard l'un de l'autre.On each of the side plates 3 is fixed a
Chacune des plaques latérales 3 est aussi percée de trous 10 dont les centres sont disposés sur une ligne parallèle à la longueur de la glissière 9 de la même plaque et distant d'elle d'une longueur inférieure à la longueur d'un panneau 4 ou 5 d'un couple. Les trous 10 d'une même plaque 3 sont deux à deux équidistants. Un trou 10 d'une plaque 3 correspond à un trou 10 de l'autre plaque 3, ceci de manière que leur axe commun soit perpendiculaire à chacun des plans formés par les plaques 3.Each of the side plates 3 is also pierced with
Dans les gaines d'extrémité 7, 8 d'un couple ainsi qu'à l'intérieur de l'angle formé dans une zone d'articulation 11 de l'embase 6 entre les deux panneaux 5, 6 d'un même couple, sont enfilées des tiges transversales 12, 13. Les deux extrémités des tiges 12 enfilées dans toutes les gaines 7 et 8 des embases 6 de la structure sont, respectivement, montées dans les fonds des deux glissières 9 qui se font face. Les deux extrémités des tiges 13 enfilées dans les zones d'articulation 11 des couples de panneaux de la structure sont respectivement montées dans les trous 10 des plaques latérales 3. Les tiges 12 sont montées coulissantes dans les glissières 9. Les tiges 12 et 13 sont toutes parallèles entre elles. De plus, les deux panneaux 4, 5 d'un couple forment un dièdre dont les demi-plans sont orthogonaux aux plans formés par les plaques latérales 3. Un dièdre de la structure se déduit d'un autre dièdre adjacent par une simple translation d'un vecteur parallèle à la longueur des glissières 9.In the
Avantageusement, les deux glissières 9 supportant, de chaque côté, les tiges 12 enfilées dans les gaines 7, 8 des embases 6 de la structure sont montées sur les plaques latérales 3 de manière à pouvoir être déplacées longitudinalement (flèches A) afin de fixer, par le réglage de leur distance à la rangée de trous 10, la tension de chaque panneau 1, 2 des couples de la structure.Advantageously, the two
A l'intersection de deux couples 1, 2 de panneaux, la gaine 8 d'un couple 1 et la gaine 7 de l'autre couple 2 sont en contact l'une contre l'autre. Pour assurer une meilleure étanchéité à ce niveau, on a prévu une plaque 14 en forme de "U" aux ailes évasées et venant recouvrir, après montage, chacune des gaines 7 et 8 des deux couples 1, 2.At the intersection of two
L'embase 6 peut être constituée de deux demi-embases, une sous chaque panneau reliées entre elles par des moyens qui forment la zone d'articulation 11 entre les deux panneaux d'un couple.The
L'ensemble panneaux 1, 2 - glissières 9, 10 - plaques latérales forme un filtre à air à usage industriel. L'air vicié entre dans les angles formés par deux panneaux successifs de la structure et traverse, pour filtrage, une seule épaisseur de panneau (flèche B).The set of
L'avantage de la structure de la présente invention sur les structures de l'art antérieur réside dans le fait que les panneaux sont montés par couple sur les glissières. Lorsque le nombre de panneaux à disposer dans le filtre est important, ce qui est, en général, le cas, ces panneaux sont faciles à monter et à démonter et donc faciles à changer.The advantage of the structure of the present invention over the structures of the prior art lies in the fact that the panels are mounted in pairs on the rails. When the number of panels to be placed in the filter is large, which is, in general, the case, these panels are easy to assemble and disassemble and therefore easy to change.
