Abstract

A device has an inlet cover (6) and a cleaning cover (8) fixed in a distributor (4), and a filter medium (7) fixed around the distributor. A shaft (1) permits to drive in rotation an inlet flap (3) and a cleaning flap (5) in a synchronous manner such that a channel of the distributor is in filter medium cleaning phase and other channels of the distributor are in filtering phase.

Description

La présente invention concerne un dispositif auto-nettoyant de filtrationThe present invention relates to a self-cleaning filtration device

deof

fluides.fluids.

La filtration de fluides est traditionnellement assurée par des cartouches statiques, ce qui présente l'inconvénient de nécessiter le remplacement des-dites cartouches.  Filtration of fluids is traditionally provided by static cartridges, which has the disadvantage of requiring the replacement of said cartridges.

Le dispositif selon l'invention permet de remedier à ce problème par le biais d'un mécanisme assurant l'auto-régénération du media filtrant. Le principe étant d'assurer la filtration sur la majeure partie du media filtrant alors qu'une partie du media filtrant est isolée et régénérée par un contre-courant de décolmatage. A cet effet, le mécanisme est pourvue d'un distributeur permettant de diviser la surface du media filtrant en canaux. Un couvercle d'entrée avec son volet d'entrée achemine le fluide à filtrer dans les canaux dits de filtration du distributeur afin de répartir le fluide sur la surface dite en phase de filtration du media filtrant. Ce faisant, le volet d'entrée ferme un canal du distributeur, ci-après nommé canal de décolmatage. Un couvercle de nettoyage avec son volet de nettoyage ouvre ce canal de décolmatage assurant ainsi la régénération par contre-courant sur la surface dite en phase de décolmatage du media filtrant. Les volets d'entrée et de nettoyage sont entrainés par un arbre afin de synchroniser ces derniers et de permettre la régénération du media filtrant de manière cyclique.  The device according to the invention makes it possible to remedy this problem by means of a mechanism ensuring the self-regeneration of the filter media. The principle is to ensure filtration over most of the filter medium while a portion of the filter media is isolated and regenerated by a declogging counter-current. For this purpose, the mechanism is provided with a distributor for dividing the surface of the filter media into channels. An inlet cover with its inlet flap conveys the fluid to be filtered in the said filtration channels of the distributor in order to distribute the fluid on the so-called filtration surface of the filter media. In doing so, the inlet flap closes a distributor channel, hereinafter called unclogging channel. A cleaning cover with its cleaning flap opens the unclogging channel thus ensuring regeneration against the current on the so-called unclogging surface of the filter medium. The inlet and cleaning flaps are driven by a shaft in order to synchronize the latter and to allow the regeneration of the filter media cyclically.

Selon des modes particuliers de réalisation: le distributeur peut contenir un nombre indéterminé de canaux.  According to particular embodiments: the dispenser may contain an indeterminate number of channels.

- Les canaux du distributeur pourront etre inclinés.  - The distributor channels may be inclined.

- le volet d'entrée peut fermer plus qu'un canal du distributeur.  - the entry flap can close more than one distributor channel.

l'orifice du volet de sortie peut-etre du type trou circulaire, oblong, fente.  the orifice of the outlet flap may be of the type circular hole, oblong, slot.

l'entrainement de l'arbre peut être assuré par un moteur électrique ou par un générateur hydraulique.  the drive of the shaft can be provided by an electric motor or a hydraulic generator.

- le cycle de régénération peut être réalisé de manière continue ou interrompue. Les dessins annexés illustrent l'invention: La figure 1 réprésente l'invention coté entrée.  the regeneration cycle can be carried out continuously or interrupted. The accompanying drawings illustrate the invention: FIG. 1 represents the invention on the input side.

La figure 2 réprésente l'invention en coupe.  Figure 2 shows the invention in section.

En référence à ces dessins, le dispositif se compose d'un couvercle entrée (6) avec son volet d'entrée (3) par lequel le fluide à filtrer s'achemine dans les canaux de filtration du distributeur (4). Les canaux de filtration sont fermés à leurs extrémités par le couvercle de nettoyage (8) et le volet de nettoyage (5) de sorte à forcer la filtration du fluide à travers le media filtrant (7). En même temps, le volet d'entrée (3) ferme un canal du distributeur, ci-après nommé le canal de décolmatage, alors que le volet de nettoyage (5) ouvre ce canal par le biais d'un orifice. Ce faisant, une partie du fluide filtré traverse le media filtrant (7) à contre-courant le long du canal de décolmatage permettant de régénérer le media filtrant (7). Un arbre (1) entraine en rotation le volet d'entrée (3) et le volet de nettoyage (5) par des clavettes (2) de sorte à assurer une régénération cyclique du media filtrant (7).  With reference to these drawings, the device consists of an inlet cover (6) with its inlet flap (3) through which the fluid to be filtered flows into the filtration channels of the distributor (4). The filter channels are closed at their ends by the cleaning cover (8) and the cleaning flap (5) so as to force the filtration of the fluid through the filter medium (7). At the same time, the inlet flap (3) closes a distributor channel, hereinafter called the unclogging channel, while the cleaning flap (5) opens this channel through an orifice. In doing so, a portion of the filtered fluid passes through the filter media (7) countercurrently along the unclogging channel for regenerating the filter medium (7). A shaft (1) rotates the inlet flap (3) and the cleaning flap (5) by keys (2) so as to ensure a cyclic regeneration of the filter medium (7).

Le couvercle d'entrée (6) et le couvercle de nettoyage (8) sont encastrés dans le distributeur (4) autour duquel est encastré le media filtrant (7). L'assemblage est finalisé par la butée (9) permettant de maintenir le mécanisme mono-bloc.  The inlet cover (6) and the cleaning cover (8) are embedded in the distributor (4) around which the filter media (7) is embedded. The assembly is finalized by the stop (9) to maintain the single-block mechanism.

A titre d'exemple non limitatif, le dispositif s'inscrira dans un cylindre de 100 mm de diamètre et de 200 mm de hauteur.  By way of non-limiting example, the device will fit in a cylinder 100 mm in diameter and 200 mm in height.

Le dispositif selon l'invention est particulièrement destiné à filtrer les huiles et combustibles de moteurs thermiques.  The device according to the invention is particularly intended to filter the oils and fuels of thermal engines.
