Description
La présente invention concerne des perfectionnements apportés a l'ensemble de cartouche de filtration faisant l'objet du brevet principal n0 82/01332. The present invention relates to improvements made to the filter cartridge assembly which is the subject of main patent No. 82/01332.
Ce brevet principal décrit une cartouche de filtration généralement cylindrique comportant des flasques terminaux sensiblement situés dans des plans perpendiculai- res a l'axe longitudinal de la cartouche et pourvus d'une cuvette annulaire périphérique et d'une collerette centrale. This main patent describes a generally cylindrical filtration cartridge comprising end plates substantially situated in planes perpendicular to the longitudinal axis of the cartridge and provided with a peripheral annular cup and a central collar.
Ces flasques maintiennent les parois perforées interne et externe d une chambre annulaire destinée a contenir un maté- riau de filtratione la paroi perforée interne réalisant un passage interne longitudinal. En outre les flasques sont fi xés mécaniquement a au moins l'une des deux parois interne et externe,par exemple au moyen de rivets et un élément fil- trant externe dont les extrémités s'étendent dans la cuvette annulaire périphérique est maintenu en place par une résine adhésive. La combinaison de la fixation mécanique et de la résine adhésive constitue un tout assurant a la fois une bon ne tenue et une bonne étanchéité de la cartouche au niveau des flasques.These flanges maintain the internal and external perforated walls of an annular chamber intended to contain a filtration material. The internal perforated wall providing an internal longitudinal passage. In addition, the flanges are mechanically fixed to at least one of the two internal and external walls, for example by means of rivets and an external filter element, the ends of which extend into the peripheral annular bowl is held in place by an adhesive resin. The combination of mechanical fixing and adhesive resin constitutes a whole ensuring both good hold and good sealing of the cartridge at the flanges.
Les cartouches de filtration auxquelles s'applique la présente invention, destinées a être interposées sur le trajet d'un liquide Si filtrer, comportent des moyens de fil- tration concentriques traversés successivement par le liquide de. Pour un fonctionnement efficace de-la cartouche, il est nécessaire que celle-ci régénère la plus grande quantité possible de liquide par unité de temps. The filter cartridges to which the present invention applies, intended to be interposed on the path of a liquid Si to filter, comprise concentric filtration means successively traversed by the liquid. For efficient operation of the cartridge, it is necessary for the cartridge to regenerate the greatest possible amount of liquid per unit of time.
Un objet de la présente invention est de permettre la réalisation d'une cartouche de filtration dont la présence n'entraine pas de diminution excessive du débit du liquide filtre. An object of the present invention is to allow the production of a filtration cartridge the presence of which does not cause an excessive reduction in the flow rate of the filter liquid.
Un autre objet de la présente invention est de permettre la réalisation d'une cartouche de filtration pouvant être aisément assemblée a d'autres cartouches de même type en vue de réaliser un filtre modulaire. Another object of the present invention is to allow the production of a filtration cartridge which can be easily assembled with other cartridges of the same type in order to produce a modular filter.
Pour cela, on prévoit, selon la présente invention, de doter chaque flasque d'une partie tronconique1 cette disposition permettant de déporter axialement la partie centra- le des flasques vers l'extérieur de la cartouche.Selon un mode de réalisation plus particulier de la présente invention, la partie tronconique s 'étend radialement vers leex trieur de la cartouche jusque a la cuvette annulaire du flasque, et radialement vers l'axe de la cartouche jusqu a la collerette centrale. For this, provision is made, according to the present invention, to provide each flange with a frustoconical part1 this arrangement making it possible to axially offset the central part of the flanges towards the outside of the cartridge. According to a more particular embodiment of the present invention, the frustoconical portion extends radially towards the sorter of the cartridge up to the annular cup of the flange, and radially towards the axis of the cartridge up to the central flange.
D'autres caractéristiques et avantages de la présente invention apparattront lors de la description suivante faite an liaison avec les dessins ci--joints dans lesquels:
La figure 1 représente schématiquement, an coupe longitudinale, une première variante de réalisation d'un ensemble de cartouche de filtration selon la présente inventison; et
La figure 2 représente schém#tiquement,en coupe longitudinale, une deuxième variante de réalisation d'un ensemble de cartouche de filtration selon la présente invention.Other characteristics and advantages of the present invention will become apparent from the following description made in connection with the attached drawings in which:
Figure 1 shows schematically, in longitudinal section, a first alternative embodiment of a filter cartridge assembly according to the present invention; and
FIG. 2 schematically represents, in longitudinal section, a second alternative embodiment of a filter cartridge assembly according to the present invention.
Sur la figure 1, on reconnaît1 entre deux flasques d'extrémite 1 présentent des rebords périphériques 2, une couronne cylindrique périphérique de papier plissé 3 entou rrnt une chambre annulaire interne 4 délimitée par une paroi cylindrique de rétention pexfoxée externe 5 et une paroi cylindrique de rétention perforée interne 6, laquelle délimite en outre un passage interne longitudinal 7 débou chant aux deux extrémités de la cartouche au centre des flasques 1.Ainsi, qu'il est connu dans la technique considérée, la chambre annulaire 4 est remplie par un trou (non représenté),formé dans un des flasques,d'un matériau divisé de filtration 8, constitué typiquement d'un mélange de particules de charbon actif et d'argile de filtration ou de charbon actif se
Chaque flasque 1 est formé pour constituer avec la collerette périphérique 2, une#cuvette annulaire 9 défit nie intérieurement par un épauloecet interne 10 en vis-à-vis de l'épaulement constitué par la collerette 2, concentriquement à cette #der#ière,i.'extension radiale de chaque cuvette 9 est déterminée de façon que puissent y être entièrement reçues les extrémité axiales de la couronne de papier plissé 3 et de la paroi cylindrique de rétention externe S.Dans un mode de réalisation préféré,le diamètre interne de la paroi cylindrique de rétention externe 5 est sensiblement identique au diamètre externe de l'épaulement interne 10 de la cuvette 9, pour que la paroi de rétention externe soit appliquée contre ce dernier en y étant fixée au droit du coude intérieur de l'épaulement 10 par des rivets autoperformants représentés symboliquement en 11 sur les figures.Conformément a l'invention, chaque flasque d'extré- mité comporte une surface tronconique 14 comprise entre l'épaulement interne 10 et une collerette-centrale 13 destinée à servir de surface d'appui a la paroi cylindrique de rétention interne 6.In Figure 1, we recognize 1 between two end flanges 1 have peripheral edges 2, a peripheral cylindrical crown of pleated paper 3 surrounding an internal annular chamber 4 delimited by a cylindrical external retaining wall 5 and a cylindrical wall internal perforated retention 6, which further delimits a longitudinal internal passage 7 leading outlet at the two ends of the cartridge at the center of the flanges 1. Thus, as is known in the art considered, the annular chamber 4 is filled with a hole ( not shown), formed in one of the flanges, of a divided filtration material 8, typically consisting of a mixture of particles of activated carbon and of filter clay or of activated carbon
Each flange 1 is formed to constitute, with the peripheral flange 2, an # annular cup # 9 defined internally by an internal shoulder 10 opposite the shoulder formed by the flange 2, concentrically with this # back # ere, i) the radial extension of each bowl 9 is determined so that the axial ends of the pleated paper crown 3 and of the cylindrical external retention wall S. can be entirely received there. In a preferred embodiment, the internal diameter of the cylindrical external retention wall 5 is substantially identical to the external diameter of the internal shoulder 10 of the bowl 9, so that the external retention wall is applied against the latter by being fixed to it at the right elbow of the shoulder 10 by self-forming rivets symbolically represented at 11 in the figures. In accordance with the invention, each end flange has a frustoconical surface 14 between the internal shoulder 10 and a central flange 13 intended to serve as a bearing surface for the cylindrical internal retention wall 6.
Selon une première variante de l'invention, représentée en figure 1, la partie tronconique 14 ne s'étend pas radialement en direction de l'axe de la cartouche jusqu'à la collerette centrale 13, mais est limitée dans cette direction par une partie de raccord 16 avec une couronne plane intermédiaire 17 entre la partie tronconique et la cQlleret- te centrale
Selon une deuxième variante représentée en figure 2, la partie tronconique 14 s'étend radialement jusqu'a la collerette centrale 13, une partie de raccord 15 réalisant la liaison entre les deux éléments précités.According to a first variant of the invention, represented in FIG. 1, the frustoconical part 14 does not extend radially in the direction of the axis of the cartridge up to the central flange 13, but is limited in this direction by a part 16 with a flat intermediate ring 17 between the frusto-conical part and the central ring
According to a second variant shown in FIG. 2, the frustoconical part 14 extends radially up to the central flange 13, a connection part 15 providing the connection between the two aforementioned elements.
Lors du montage du flasque, on coule dans la cu vette annulaire 9 de chaque flasque 1 une résine polyméri- sable à froid 12, typiquement une résine polyester ou po lypropylène en quantité suffisante pour occuper les- interstices existant entre les extrémités axiales de la couronne de papier et de la paroi cylindrique de rétention externe 5 et la cuvette 9,
Dans un mode de réalisation particulier représenté sur les figures, la partie 15 de raccord entre la partie tronconique 14 et la collerette centrale 13 est située sensiblement dans le même plan que les faces planes, perpendiculaires à l'axe longitudanal de la cartouche, du fond de la cuvette annulaire 9.Bien que cela n'ait pas été représente, la partie de raccord 15 peut également être déportée axialement vers l'intérieur ou l'extérieur de la cartouche.During the mounting of the flange, a cold polymerizable resin 12 is poured into the annular cup 9 of each flange 1, typically a polyester or polypropylene resin in sufficient quantity to occupy the gaps existing between the axial ends of the crown of paper and of the cylindrical external retention wall 5 and the bowl 9,
In a particular embodiment shown in the figures, the part 15 for connection between the frustoconical part 14 and the central flange 13 is situated substantially in the same plane as the plane faces, perpendicular to the longitudinal axis of the cartridge, from the bottom of the annular cup 9. Although this has not been shown, the connector part 15 can also be offset axially towards the inside or outside of the cartridge.
Dans le cas d'une utilisation de plusieurs cartouches mises bout à bout, cette disposition permet de réaliser une étanchéité entre deux cartouches adjacentes en appliquant soit un joint de grand diamètre sur lequel s'appuient les surfaces externes des couronnes 9 de chaque cartouche, soit un joint de petit diamètre sur lequel s'appuient les surfaces externes de la partie de raccord 15,16 de chaque cartouche. In the case of the use of several cartridges placed end to end, this arrangement makes it possible to produce a seal between two adjacent cartridges by applying either a large diameter seal on which the external surfaces of the crowns 9 of each cartridge are supported, or a small diameter seal on which the external surfaces of the connection part 15, 16 of each cartridge are supported.
Dans un mode de réalisation particulier, chaque flasque 1 avec la cuvette 9, la surface tronconique 14, la collerette centrale 13, les faces planes intermédiaires éventuelles et les différentes parties de raccords, est formé d'une seule pièce par déformation à froid d'un flanc de tôle d'acier. In a particular embodiment, each flange 1 with the bowl 9, the frustoconical surface 14, the central flange 13, the possible intermediate flat faces and the various parts of fittings, is formed in one piece by cold deformation of a side of sheet steel.
La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, elle est au contraire susceptible de modifications et de variantes qui appara#tront à. l'homme de l'art, The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and variants which will appear. the skilled person,
