Description
La présente invention se rapporte à un procédé de fabrication de corps filtrants pour cartouches de filtratison. The present invention relates to a method of manufacturing filter bodies for filter cartridges.
Pour la réalisation des cartouches de filtration, on utilise du papier filtre qui est imprégné de résine phénolique. Ce papier poreux imprégné est découpé à partir de rouleaux en bandes qui sont pliées en accordéon, et éventuellement chevronnées, puis les bandes ainsi pliées sont chauffées de manière à obtenir une polymérisation de la résine. For the production of the filter cartridges, filter paper is used which is impregnated with phenolic resin. This impregnated porous paper is cut from rolls into strips which are folded in an accordion, and possibly chevron, then the strips thus folded are heated so as to obtain a polymerization of the resin.
Dans ces fabrications, les chutes de papier filtre sont importantes et sont inutilisables. La présente invention vise un procédé qui permet, de récupérer les chutes afin de constituer des corps filtrants, plus particulièrement des tinés à des petits débits. In these productions, the scraps of filter paper are significant and cannot be used. The present invention relates to a method which makes it possible to recover the scraps in order to constitute filtering bodies, more particularly tines at small flow rates.
Le procédé selon l'invention vise à utiliser des déchets de papiers poreux imprégnés de résine phénolique et est caractérisé en ce qu'il consiste à broyer le papier pour obtenir un ensemble fibreux, à placer cet ensemble fibreux dans un moule, à presser ledit ensemble fibreux pour lui donner la forme sélectionnée du corps filtrant à réaliser, et à soumettre celui-ci à l'action de la chaleur. The method according to the invention aims to use porous paper waste impregnated with phenolic resin and is characterized in that it consists in grinding the paper to obtain a fibrous assembly, in placing this fibrous assembly in a mold, in pressing said assembly fibrous to give it the selected shape of the filtering body to be produced, and to subject it to the action of heat.
Grâce à ce processus, l'action de la chaleur permet de resouder par polymérisation de la résine phenolique, les fibres entre elles et on obtient un corps filtrant, bon marché et permettant d'assurer une filtration efficace. Thanks to this process, the action of heat makes it possible to resolder, by polymerization of the phenolic resin, the fibers between them and a filtering body is obtained, inexpensive and making it possible to ensure effective filtration.
De préférence, le corps filtrant est soumis à traction de la chaleur durant un laps de temps compris entre 10 et 30 minutes à une température comprise entre 1300C et 170OC. Preferably, the filter body is subjected to heat traction for a period of time between 10 and 30 minutes at a temperature between 1300C and 170OC.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexes, dans lesquels
Les figures 1 à 4 sont des vues schématiques imageant les différentes phases du procédé selon l'invention.The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which
Figures 1 to 4 are schematic views showing the different phases of the method according to the invention.
La figure 1 montre un rouleau de papier filtre destiné à la réalisation de filtres pour l'industrie automobile et formé d'un papier poreux imprégné de résine phénolique. FIG. 1 shows a roll of filter paper intended for the production of filters for the automobile industry and formed from porous paper impregnated with phenolic resin.
A partir du rouleau 1 on découpe des bandes 2, 3, 4 et 5 qui seront ensuite pliées en accordéon et chevronnées pour former un corps filtrant. Bien entendu, il reste une chute 6 et éventuellement une chute en fin de rouleau si ce dernier m'a pas une longueur correspondant à un multiple des corps filtrants à réaliser. From the roll 1, strips 2, 3, 4 and 5 are cut which will then be folded into an accordion and seasoned to form a filtering body. Of course, there remains a fall 6 and possibly a fall at the end of the roll if the latter does not have a length corresponding to a multiple of the filter bodies to be produced.
Les chutes 6 sont placées dans un broyeur 7 qui détache les unes des autres les fibres cellulosiques de ma nière à former un ensemble fibreux 8. The scraps 6 are placed in a crusher 7 which detaches the cellulosic fibers from one another so as to form a fibrous assembly 8.
L'ensemble fibreux 8 est ensuite placé dans un moule 9 correspondant à la forme de corps filtrant à réaliser. The fibrous assembly 8 is then placed in a mold 9 corresponding to the shape of the filter body to be produced.
L'ensemble fibreux 8 est pressé dans le moule 9 de manière à obtenir un corps filtrant 10. The fibrous assembly 8 is pressed into the mold 9 so as to obtain a filter body 10.
On a représenté ici un corps filtrant affectant la forme d'un manchon cylindrique, mais, bien entendu, ledit corps pourrait avoir une forme très -différente. There is shown here a filter body affecting the shape of a cylindrical sleeve, but, of course, said body could have a very -different shape.
La pression exercée sur la matière fibreuse 8 est plus ou moins importante suivant les qualités de filtration qu'on veut donner au corps filtrant. The pressure exerted on the fibrous material 8 is more or less important depending on the filtration qualities that one wants to give to the filter body.
Le corps filtrant 10 est ensuite passé dans un four 11 ou il est soumis à l'action de la chaleur pendant un laps de temps de l'ordre de dix à trente minutes à une température comprise entre 1300C et 170 C. Grâce à l'action de la chaleur on obtient une polymérisation de la résine qui assure un ressoudage des fibres entre elles. The filter body 10 is then passed through an oven 11 where it is subjected to the action of heat for a period of the order of ten to thirty minutes at a temperature between 1300C and 170 C. Thanks to the action of heat a polymerization of the resin is obtained which ensures the fibers are joined together.
Grâce au procédé, selon l'invention, on peut réaliser des corps filtrants, plus particulièrement, pour les petits d-ébits, par exemple des filtres de dvrivations, lesdits corps étant très efficaces et bon marché puisqu'ils permettent l'utilisation, comme matière première des chutes qui sont normalement jetées. Thanks to the method according to the invention, it is possible to produce filtering bodies, more particularly, for small dbits, for example bypass filters, said bodies being very effective and inexpensive since they allow the use, as raw material from the scraps that are normally thrown away.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui vient d'être décrit et représenté. Of course, the invention is not limited to the embodiments which have just been described and shown.
On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention. Many modifications of detail can be made without departing from the scope of the invention.
