Description
La présente invention a pour objet un perfectionnement aux bougies filtrantes de matières plastiques en fusion, du type comportant essentiellement: - un média filtrant qui est l'élément actif du filtre, - un tissu métallique support ayant deux rôles:
. une fonction de drainage du fluide,
. assurer la bonne tenue mécanique de ltensemble, - un fond - deux collets assurant l'assemblage de ces trois éléments.The subject of the present invention is an improvement to filter candles of molten plastic materials, of the type essentially comprising: - a filtering medium which is the active element of the filter, - a metallic support fabric having two roles:
. a fluid drainage function,
. ensure good mechanical strength of the assembly, - a bottom - two collars ensuring the assembly of these three elements.
Ces filtres viennent se monter dans un porte-filtre en tôle perforée par exemple, ceci de manière connue de l'homme de l'art. These filters are mounted in a filter holder made of perforated sheet metal for example, this in a manner known to those skilled in the art.
Jusqu'à présent, les corps de certaines bougies filtrantes sont constitués de tissu métallique ayant un sens de fil parallèle à l'axe de bougie. Until now, the bodies of certain filter candles are made of metallic fabric having a thread direction parallel to the candle axis.
Ces dernières sont donc rigides, indéformables et doivent avoir un diamètre légèrement inférieur au diamètre intérieur du porte-filtre pour s'engager facilement. Ce jeu fonctionnel sur une bougie indéformable présente des risques d'éclatement, notamment lors de l'utilisation avec un fluide visqueux et sous forte pression. The latter are therefore rigid, non-deformable and must have a diameter slightly smaller than the inside diameter of the filter holder for easy engagement. This functional play on a non-deformable candle presents risks of bursting, in particular during use with a viscous fluid and under high pressure.
D'autre part, ces filtres se colmatent à l'usage et il y a une certaine difficulté pour extraire les bougies de leur porte-filtre lors de leur remplacement. On the other hand, these filters clog up in use and there is a certain difficulty in extracting the spark plugs from their filter holder during their replacement.
La présente invention a pour but de remédier à ces inconvénients. The present invention aims to remedy these drawbacks.
Conformément à l'invention, ce résultat est obtenu avec une bougie filtrante de matière plastique en fusion, du type comportant essentiellement: - un média filtrant qui est l'élément actif du filtre, - un tissu métallique support ayant deux rôles:
. une fonction de drainage du fluide,
. assurer la bonne tenue mécanique de l'ensemble, - un fond, - deux collets assurat l'assemblage de ces trois éléments caractérisée en ce que le tissu métallique support est constitué de fils décalés angulairement par rapport à la génératrice du cylindre de la bougie.In accordance with the invention, this result is obtained with a filter candle of molten plastic, of the type essentially comprising: - a filtering medium which is the active element of the filter, - a metallic support fabric having two roles:
. a fluid drainage function,
. ensure the good mechanical strength of the assembly, - a bottom, - two collars ensuring the assembly of these three elements, characterized in that the metallic support fabric consists of wires offset angularly relative to the generator of the cylinder of the spark plug.
Avantageusement, I'angle sera de 45". On obtient ainsi une bougie déformable. Advantageously, the angle will be 45 ". This gives a deformable candle.
On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels: - la figure I est une représentation d'une bougie traditionnelle; - la figure 2 est une vue en perspective éclatée d'une bougie de l'art antérieur; - la figure 3A illustre la trame d'un tissu métallique de l'art antérieur; - la figure 3B illustre la trame d'un tissu métallique conforme à l'invention; - la figure 4 illustre la mise en place de la bougie filtrante dans le porte-filtre; - la figure 5 représente la bougie filtrante en position d'utilisation dans son porte-filtre; - la figure 6 représente l'extraction de la bougie filtrante de son porte-filtre; - la figure 7 représente la trame d'un tissu métallique utilisée conformément à l'invention, agrandie. The invention will be better understood with the aid of the description given below of an embodiment given by way of nonlimiting example, with reference to the appended drawings in which: - Figure I is a representation of 'a traditional candle; - Figure 2 is an exploded perspective view of a candle of the prior art; - Figure 3A illustrates the frame of a metallic fabric of the prior art; - Figure 3B illustrates the frame of a metallic fabric according to the invention; - Figure 4 illustrates the placement of the filter candle in the filter holder; - Figure 5 shows the filter candle in the use position in its filter holder; - Figure 6 shows the extraction of the filter candle from its filter holder; - Figure 7 shows the frame of a metallic fabric used in accordance with the invention, enlarged.
Les bougies filtrantes (1) sont généralement constituées de cinq parties distinctes à savoir - un média filtrant (2) qui est l'élément actif du fiRre, - une tissu métallique support (3) ayant deux rôles:
une fonction de drainage du fluide
assurer la bonne tenue mécanique de l'ensemble - un fond (4) - deux collets (5,6) assurant l'assemblage de ces trois éléments.The filter candles (1) generally consist of five distinct parts, namely - a filter medium (2) which is the active element of the filter, - a metallic support fabric (3) having two roles:
a fluid drainage function
ensure good mechanical strength of the assembly - a base (4) - two collars (5,6) ensuring the assembly of these three elements.
Ces filtres viennent se monter dans un porte-filtre (7) en tôle perforée par exemple. These filters are mounted in a filter holder (7) made of perforated sheet for example.
Les tissus métalliques (8) de l'art antérieur ont une trame parallèle à la génératrice (9) du cylindre. The metallic fabrics (8) of the prior art have a frame parallel to the generator (9) of the cylinder.
Conformément à l'invention, le tissu métallique du support (10) est orienté d'un certain angle par rapport à la génératrice (9). According to the invention, the metallic fabric of the support (10) is oriented at a certain angle relative to the generator (9).
Cet angle des fils constitutifs est généralement égal à 45" par rapport à la génératrice du cylindre afin d'obtenir la déformabilité maximale, ainsi qu'une symétrie, afin d'équilibrer l'aptitude à la déformation. This angle of the constituent wires is generally equal to 45 "with respect to the generatrix of the cylinder in order to obtain maximum deformability, as well as symmetry, in order to balance the ability to deform.
Ceci apparaît clairement à la figure 7.This is clearly shown in Figure 7.
On obtient alors les avantages suivants: - le corps de la bougie devenant déformable, il assure un plaquage parfait avec le support au moment de la montée en pression. Ceci permet d'éviter les risques d'éclatement du corps de la bougie (cf. figure 5) - d'autre part, du fait de la déformabilité, on obtient une certaine facilité d'extraction de la bougie lors de son remplacement. The following advantages are then obtained: - the body of the spark plug becoming deformable, it ensures perfect plating with the support when the pressure builds up. This makes it possible to avoid the risks of bursting of the body of the candle (cf. FIG. 5) - on the other hand, due to the deformability, a certain ease of extraction of the candle is obtained during its replacement.
En effet, il suffit de saisir la bougie par une extrémité au moyen d'une griffe (11) pénétrant dans l'embout du tissu métallique puis de la faire tourner autour de l'axe longitudinal. Le diamètre de la bougie ayant alors diminué du fait de la rotation, il n'y a plus qu'à tirer sur l'outil parallèlement à l'axe longitudinal pour extraire la bougie. Indeed, it suffices to grasp the candle at one end by means of a claw (11) penetrating into the end of the metallic fabric and then to rotate it around the longitudinal axis. The diameter of the spark plug then having decreased due to the rotation, there is only to pull the tool parallel to the longitudinal axis to extract the spark plug.
- enfin, la découpe à 45" réduit le phénomène d'effilochage des bords du tissu métallique, car pour l'utilisation en filtration il ne faut pas qu'un fil se détachant du tissu métallique puisse se mélanger au produit filtré. - finally, the cut to 45 "reduces the phenomenon of fraying of the edges of the metallic fabric, because for the use in filtration it is not necessary that a wire detaching from the metallic fabric can mix with the filtered product.
