Abstract

The automatic magnetic filter cleaning mechanism has a perforated scraper plate (12) with openings of a slightly larger dia. than the magnetic retaining rods (8) passing through them. A motor drive unit (14), outside the closed housing (1), moves the plate down over the rods along their whole length to detach the particles sepd. from the recirculating fluid.

Description

L'invention a pour objet un dispositif de nettoyage de barreaux de retenue de particules magnétisables en suspension dans les fluides, notamment pour filtres magnétiques. The invention relates to a device for cleaning rods retaining magnetizable particles suspended in fluids, in particular for magnetic filters.

La plupart des filtres magnétiques connus sont essentiellement constitués d'un corps cylindrique équipé d'une entrée et d'une sortie de fluide, à l'intérieur duquel sont fixés des barreaux verticaux magnétiques, généralement rattachés à un couvercle supérieur démontable. Les particules magnétisables gênantes en suspension dans des fluides tels que l'eau, les condensats, les huiles, les carburants qui circulent dans ledit corps de filtre se déposent sur les barreaux et l'eau sort purifiée de ces particules. Most known magnetic filters essentially consist of a cylindrical body equipped with a fluid inlet and outlet, inside which are fixed vertical magnetic bars, generally attached to a removable top cover. The annoying magnetizable particles suspended in fluids such as water, condensates, oils, fuels which circulate in said filter body are deposited on the bars and the water comes out purified from these particles.

Ces filtres sont très efficaces mais les barreaux se saturent rapidement, d'où la nécessité de les nettoyer avant d'atteindre le seuil de saturation car au-delà de ce seuil, l'action magnétique est stoppée et les liquides passant à travers le filtre ne sont plus débarassés de leurs particules magnétisables. These filters are very effective but the bars quickly saturate, hence the need to clean them before reaching the saturation threshold because beyond this threshold, the magnetic action is stopped and the liquids passing through the filter. are no longer free of their magnetizable particles.

L'appréhension de ce seuil est aléatoire et pour nettoyer les barreaux, on est amené à interrompre le passage du liquide dans le filtre puis à isoler celui-ci, le vidanger et démonter son couvercle, enfin à sortir les barreaux, les nettoyer, refermer le filtre, le remplir et réouvrir la distribution -opération longue, fréquente et coûteuse en main-d'oeuvre-. The apprehension of this threshold is random and to clean the bars, it is necessary to interrupt the passage of the liquid in the filter then to isolate the latter, drain it and dismantle its cover, finally to remove the bars, clean them, close again the filter, fill it and reopen the distribution - long, frequent and labor-intensive operation.

L'invention apporte une solution avantageuse à ce problème en ce qu'elle propose un dispositif de nettoyage automatique de barreaux de retenue de particules magnétisables en suspension dans un fluide circulant à l'intérieur d'une enceinte fermée entre une entrée et une sortie, en passant au travers et le long desdits barreaux sur lesquels se déposent les particules, dispositif selon lequel une plaque de raclage percée de lumières d'un diamètre légèrement supérieur à celui des barreaux et réparties comme lui est enfilée sur lesdits barreaux et manoeuvrée par un mécanisme moteur extérieur à l'enceinte fermée qui permet à la plaque de racler les barreaux sur toute leur longueur pour que les particules magnétisables soient chassées et entraînées par le flux de fluide. The invention provides an advantageous solution to this problem in that it provides an automatic cleaning device for bars retaining magnetizable particles suspended in a fluid circulating inside a closed enclosure between an inlet and an outlet, passing through and along said bars on which the particles are deposited, device according to which a scraper plate pierced with lights of a diameter slightly greater than that of the bars and distributed as it is threaded on said bars and operated by a mechanism motor outside the closed enclosure which allows the plate to scrape the bars over their entire length so that the magnetizable particles are driven out and entrained by the flow of fluid.

Avantageusement, le mécanisme moteur est un vérin monté sur le couvercle de l'enceinte fermée, dont la tige de commande de la plaque de raclage traverse ledit couvercle ainsi qu'une plaque de fixation des barreaux. Advantageously, the motor mechanism is a jack mounted on the cover of the closed enclosure, the control rod of the scraper plate passing through said cover as well as a bar fixing plate.

D'autres caractéristiques particulières et avantages de l'invention apparaîtront à la lecture de la description qui va suivre d'un exemple de réalisation dans lequel on fait référence aux dessins annexés qui représentent
Figure 1. une vue en coupe d'un filtre magnétique équipé du dispositif de nettoyage.Other particular characteristics and advantages of the invention will appear on reading the following description of an embodiment in which reference is made to the accompanying drawings which represent
Figure 1. a sectional view of a magnetic filter fitted with the cleaning device.

Figure 2. la même vue du filtre au cours de l'opération de nettoyage. Figure 2. the same view of the filter during the cleaning operation.

Le filtre magnétique représenté à la Figure 1 se compose essentiellement d'une enceinte fermée 1 en forme de corps cylindrique disposant à sa partie supérieure d'une ouverture 2 d'entrée de fluide et à sa partie inférieure d'une ouverture 3 de sortie. Il est également prévu en partie basse un orifice de vidange 4 obturé par une vanne 5. The magnetic filter shown in Figure 1 consists essentially of a closed enclosure 1 in the form of a cylindrical body having at its upper part an opening 2 for fluid inlet and at its lower part an opening 3 for outlet. There is also provided in the lower part a drain orifice 4 closed by a valve 5.

Le corps 1 est fermé par un couvercle 6 démontable à l'aide d'une pluralité de fixations 7 à vis-écrou. Des évents 10 sont prévus dans ledit couvercle, et des prises 15 pour manomètres sur le côté du filtre. A l'intérieur du corps cylindrique, plusieurs barreaux magnétiques 8, avantageusement soutenus à leur partie supérieure par une plaque de fixation 9, s'étendent verticalement sur toute la hauteur du filtre. De façon classique les barreaux ont une section circulaire et sont répartis sur la plaque de fixation selon un ou plusieurs cercles pour occuper le plus grand volume possible du corps cylindrique. En outre un panier filtrant 11 enveloppe les barreaux. Il est amovible et permet le recueil de boues et autres corps étrangers.The body 1 is closed by a removable cover 6 using a plurality of fasteners 7 with screw-nut. Vents 10 are provided in said cover, and sockets 15 for pressure gauges on the side of the filter. Inside the cylindrical body, several magnetic bars 8, advantageously supported at their upper part by a fixing plate 9, extend vertically over the entire height of the filter. Conventionally, the bars have a circular section and are distributed on the fixing plate in one or more circles to occupy the largest possible volume of the cylindrical body. In addition, a filter basket 11 envelops the bars. It is removable and allows the collection of sludge and other foreign bodies.

Une plaque de raclage 12 dans laquelle sont percées des lumières d'un diamètre légèrement supérieur à celui des barreaux est enfilée sur ces derniers et placée sous la plaque de fixation 9. Les lumières de la plaque sont réparties bien entendu comme les barreaux. Dans exemple représenté, la plaque, pour s'intégrer dans le corps cylindrique, est ronde, mais sa forme extérieure pourrait être différente. La plaque de raclage est montée en bout d'une tige ou bras 13 qui traverse la plaque de fixation 9 et le couvercle 6, une garniture appropriée étant prévue dans l'orifice de passage de ce couvercle conforme à la pression envisagée dans le filtre de façon à rendre ce passage étanche. Cette tige est solidaire d'un vérin hydraulique ou pneumatique 14 constituant le mécanisme moteur de la plaque, mécanisme qui se trouve sur le couvercle du filtre, c'est-à-dire à l'extérieur du corps cylindrique et qui peut dans certains cas, assurer lui-même par une bride l'étanchéité de sa tige à travers le couvercle. Le vérin a une course de bras sensiblement égale ou inférieure à la longueur des barreaux magnétiques. A scraper plate 12 in which are pierced lights of a diameter slightly greater than that of the bars is threaded on the latter and placed under the fixing plate 9. The lights of the plate are of course distributed like the bars. In the example shown, the plate, to integrate into the cylindrical body, is round, but its external shape could be different. The scraper plate is mounted at the end of a rod or arm 13 which passes through the fixing plate 9 and the cover 6, a suitable lining being provided in the passage orifice of this cover conforming to the pressure envisaged in the filter. so as to seal this passage. This rod is integral with a hydraulic or pneumatic cylinder 14 constituting the motor mechanism of the plate, a mechanism which is located on the cover of the filter, that is to say outside the cylindrical body and which can in certain cases , itself ensure by a flange the tightness of its rod through the cover. The cylinder has an arm stroke substantially equal to or less than the length of the magnetic bars.

Pendant le cycle normal de filtration de l'appareil, illustré à la figure 1 des vannes non représentées commandant les ouvertures d'entrée 2 et de sortie 3 du corps cylindrique 1 sont ouvertes, tandis que la vanne de vidange 5 est fermée. Le vérin 14 est au repos, la tige 13 rétractée, et la plaque de raclage 12 est en position haute. Le liquide à traiter, circulant dans le filtre entre l'entrée 2 et la sortie 3, comme le montrent les flèches, passe à travers et le long des barreaux 8 sur lesquels se fixent les particules magnétisables 16, par exemple de l'oxyde de fer. During the normal filtration cycle of the device, illustrated in FIG. 1, valves not shown controlling the inlet 2 and outlet 3 openings of the cylindrical body 1 are open, while the drain valve 5 is closed. The jack 14 is at rest, the rod 13 retracted, and the scraper plate 12 is in the high position. The liquid to be treated, circulating in the filter between inlet 2 and outlet 3, as shown by the arrows, passes through and along the bars 8 on which the magnetizable particles 16 are fixed, for example oxide of iron.

La figure 2 montre le filtre lors de l'opération de nettoyage. Dans ce cas, on ferme la vanne de sortie 3 on ouvre la vanne de vidange 5 et on actionne le vérin 14 qui par l'intermédiaire de sa tige 13 va déplacer la plaque de raclage 12 vers le bas. Au fur et à mesure de son mouvement de coulissement sur les barreaux 8, les particules magnétisables 16 retenues sur les barreaux seront raclées par la plaque 12 puis chassées et entraînées par le flux du fluide vers l'orifice de vidange 4 dont la vanne est ouverte. A la fin du cycle de nettoyage, quand la plaque de raclage est arrivée en position basse, on ferme la vanne de vidange puis on remonte le vérin dans sa position initiale et on réouvre la vanne de ltouverture de sortie 3. Le filtre est ainsi prêt à remplir à nouveau sa fonction normale et n'a pas eu à être démonté. L'opération s'est donc effectuée sans intervention interne et en peu de temps. Figure 2 shows the filter during the cleaning operation. In this case, the outlet valve 3 is closed, the drain valve 5 is opened and the actuator 14 is actuated which, by means of its rod 13, will move the scraper plate 12 downwards. As it slides on the bars 8, the magnetizable particles 16 retained on the bars will be scraped by the plate 12 then driven out and entrained by the flow of the fluid towards the drain orifice 4 whose valve is open . At the end of the cleaning cycle, when the scraper plate has reached the low position, the drain valve is closed, then the cylinder is returned to its initial position and the valve of the outlet opening 3 is reopened. The filter is thus ready. to perform its normal function again and did not have to be disassembled. The operation was therefore carried out without internal intervention and in a short time.

L'invention n'est pas limitée à l'exemple de réalisation décrit et englobe aussi des variantes notamment en ce qui concerne l'organe moteur de la plaque de raclage qui, au lieu d'un vérin, pourrait être une vis sans fin actionnée par une manivelle ou un moteur électrique. The invention is not limited to the example of embodiment described and also encompasses variants in particular as regards the motor member of the scraper plate which, instead of a jack, could be an actuated worm by a crank or an electric motor.

L'organe moteur n'est pas non plus nécessairement à l'aplomb de la tige de manoeuvre, et il se trouve alors décentré par rapport à la plaque de raclage le déplacement vers le bas ou le haut de la plaque de raclage étant alors assuré par l'intermédiaire de bielles ou leviers appropriés. De même la manoeuvre de la plaque de raclage pourrait être assurée manuellement, à l'aide de leviers appropriés.The driving member is also not necessarily plumb with the operating rod, and it is then off-center with respect to the scraper plate, the downward or upward movement of the scraper plate then being ensured by means of suitable rods or levers. Likewise, the operation of the scraper plate could be ensured manually, using appropriate levers.

Le dispositif de nettoyage automatique selon l'invention n'est pas non plus limité au domaine d'application préférentiel des filtres magnétiques précédemment décrits, mais peut être utilisé pour éliminer les particules magnétisables de fluides en circulation dans des circuits de fluide quelconques, tels que dans des installations de chauffage.  The automatic cleaning device according to the invention is also not limited to the preferential field of application of the magnetic filters previously described, but can be used to remove the magnetizable particles of fluids circulating in any fluid circuits, such as in heating systems.
