Abstract

Filtration and anti scale treatment of water. A vessel (1) contains a filtration cartridge (9) maintained in the vessel by a distribution head (4) with water entry (5) and exit (7) points. A magnetic treatment capsule is mounted on the cartridge (9) and connected to the outlet such that water passing through the cartridge is directed by the magnetic treatment capsule. The treatment capsule has a permanent magnet (17) on a pipe (19) centred within the channel (12) of the cartridge (9). This pipe (19) is extended by a magnetic core on which a cowl (24) is threaded defining a boss which cooperates with a seat to form an air gap through which water from the channel (12) passes. The cowl (24) slides on the core such that the air gap is dependent on water flow. The air gap is in the form of a nozzle. The initial position of the cowl (24) is controlled by a screw (37). Fins (31) at the entry to the vessel create a cyclone effect. The filtration cartridge (9), treatment capsule, and tubular spacer (14) are fixed between the distribution head (4) and the base of the vessel (1) by joints (10, n/s). Conductors in the capsule are connected to a current supply and an apparatus for measurement of electrical potential to control treatment. A valve (34) at the base of the vessel (1) with control rod (36) is connected via a spring (33) to a couple (32) supporting the cartridge (9). The magnet (17) is circular and can be mounted between two holders (38, 39). USE/ADVANTAGE - Scale prevention in water. Treatment can be carried out using removable cartridges.

Description

La présente invention est relative au traitement de l'eau et, plus particulièrement, elle concerne un dispositif pour empêcher le dépôt de tartre dans des canalisations. The present invention relates to water treatment and, more particularly, it relates to a device for preventing the deposit of scale in pipes.

L'invention vise en outre la filtration et éventuellement d'autres traitements pouvant être exécutés au moyen de cartouches appropriées et interchangeables. L'invention vise aussi à permettre l'utilisation de dispositifs de filtrage comportant une cuve contenant une cartouche amovible pour mettre en oeuvre un traitement magnéto-hydrodynamique sans qu'il en résulte de modifications au moins des têtes distributrices dont sont munis les dispositifs de filtrage connus. The invention further relates to filtration and possibly other treatments which can be carried out by means of suitable and interchangeable cartridges. The invention also aims to allow the use of filtering devices comprising a tank containing a removable cartridge to implement a magneto-hydrodynamic treatment without resulting in modifications to at least the dispensing heads with which the filtering devices are provided. known.

Conformément à l'invention, le dispositif de filtrage et de traitement d'eau pour prévenir l'incrustration de tartre comportant une cuve contenant une cartouche filtrante maintenue dans la cuve par une tête distributrice dont un embout d'entrée débouche entre la cuve et la cartouche filtrante et un embout de sortie communiquant avec un canal de la cartouche filtrante est caractérisé en ce que ladite cartouche filtrante est surmontée par une capsule magnétique de traitement maintenue contre la tête distributrice et communiquant avec l'embout de sortie de ladite tête de sorte que l'eau ayant traversé la cartouche filtrante est contrainte à passer à travers la capsule de traitement. According to the invention, the filtering and water treatment device to prevent the incrustation of tartar comprising a tank containing a filter cartridge maintained in the tank by a dispensing head, an inlet nozzle of which opens out between the tank and the filter cartridge and an outlet nozzle communicating with a channel of the filter cartridge is characterized in that said filter cartridge is surmounted by a magnetic treatment capsule held against the dispensing head and communicating with the outlet nozzle of said head so that the water having passed through the filter cartridge is forced to pass through the treatment capsule.

Diverses autres caractéristiques de l'invention ressortent, d'ailleurs, de la description détaillée qui suit. Various other characteristics of the invention will emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, aux dessins annexés.  Embodiments of the subject of the invention are shown, by way of nonlimiting examples, in the accompanying drawings.

La fig. 1 est une coupe, en partie schématique, du dispositif de filtrage et de traitement d'eau de l'invention. Fig. 1 is a section, partly schematic, of the filtering and water treatment device of the invention.

La fig. 2 est une coupe partielle, à plus grande échelle, d'une partie du dispositif apparaissant à la fig.1.  Fig. 2 is a partial section, on a larger scale, of a part of the device appearing in fig.1.

La fig. 3 est une coupe transversale prise suivant la ligne III-III de la fig. 2 et illustrant une caractéristique particulière. Fig. 3 is a cross section taken along line III-III of FIG. 2 and illustrating a particular characteristic.

La fig. 4 est une coupe prise suivant la ligne
IV-IV de la fig. 3.Fig. 4 is a section taken along the line
IV-IV of fig. 3.

La fig. 5 est une coupe-élévation analogue à la fig. 1 d'une variante. Fig. 5 is a sectional elevation similar to FIG. 1 of a variant.

Le dispositif illustré aux dessins comporte une cuve 1, de préférence en matière transparente, dont la partie supérieure présente un filetage 2 sur lequel est vissée une jupe 3 d'une tête distributrice 4. The device illustrated in the drawings comprises a tank 1, preferably made of transparent material, the upper part of which has a thread 2 onto which a skirt 3 of a dispensing head 4 is screwed.

La tête distributrice 4 délimite, de façon connue, un embout d'entrée 5 destiné à être relié à un conduit 6 et un embout de sortie 7 destiné à être relié à un conduit 8. The dispensing head 4 delimits, in known manner, an inlet nozzle 5 intended to be connected to a conduit 6 and an outlet nozzle 7 intended to be connected to a conduit 8.

La cuve 1 contient une cartouche 9 constituée par un filtre un tamis ou un autre organe analogue devant retenir les impuretés contenues dans l'eau amenée par le conduit 6. The tank 1 contains a cartridge 9 constituted by a filter, a sieve or other similar member which must retain the impurities contained in the water supplied by the pipe 6.

La cartouche 9 qui doit pouvoir être changée repose sur le fond de la cuve 1 par l'intermédiaire d'une nervure 10 formant joint et est de préférence centrée par un foureau 11. The cartridge 9 which must be able to be replaced rests on the bottom of the tank 1 by means of a rib 10 forming a seal and is preferably centered by a furnace 11.

La cartouche 9 est creuse et délimite intérieurement un canal 12 par lequel l'eau s'écoule après avoir traversé la paroi de la cartouche, cette eau étant alors pré-traitée, au moins en ce qui concerne sa filtration.  The cartridge 9 is hollow and internally delimits a channel 12 through which the water flows after passing through the wall of the cartridge, this water then being pre-treated, at least as regards its filtration.

Une capsule de traitement 13 est disposée sur le dessus de la cartouche 9 et est maintenue serrée sur celle-ci par une entretoise tubulaire 14 dont le dessus est pressé par une nervure annulaire 15 ou un autre joint la reliant à la tête distributrice 4. A treatment capsule 13 is placed on top of the cartridge 9 and is held tight on it by a tubular spacer 14 the top of which is pressed by an annular rib 15 or another seal connecting it to the dispensing head 4.

Une collerette 16 de la tête distributrice est engagée dans l'entretoise tubulaire 14 pour assurer son centrage et permettre la communication avec l'embout de sortie 7 et par conséquent le conduit 8. A flange 16 of the dispensing head is engaged in the tubular spacer 14 to ensure its centering and to allow communication with the outlet nozzle 7 and consequently the conduit 8.

Ce qui précède montre que l'eau amenée par le conduit 6 est dirigée selon les flèches à l'intérieur de la cuve 1 en passant autour de la capsule de traitement 13 puis est amenée à passer à travers la cartouche 9, et à l'intérieur de la capsule de traitement 13 pour être évacuée par embout 7 et le conduit 8. The above shows that the water brought in through line 6 is directed according to the arrows inside the tank 1, passing around the treatment capsule 13 and is then brought to pass through the cartridge 9, and to the inside of the treatment capsule 13 to be evacuated by end piece 7 and the conduit 8.

La fig. 2 illustre un mode de réalisation de la capsule de traitement 13. Cette capsule comporte un aimant 17 disposé sur une collerette 18 en matière magnétique. La collerette 18 forme à une buse 19 avantageusement munie d'un joint 20 engagé dans l'alésage 12 de la cartouche 9. Fig. 2 illustrates an embodiment of the treatment capsule 13. This capsule comprises a magnet 17 placed on a collar 18 made of magnetic material. The collar 18 forms a nozzle 19 advantageously provided with a seal 20 engaged in the bore 12 of the cartridge 9.

La buse 19 est également en matière magnétique et forme un noyau 21 concentrique à l'aimant 17 et faisant saillie au dessus de celui-ci. The nozzle 19 is also made of magnetic material and forms a core 21 concentric with the magnet 17 and projecting above the latter.

Des lumières 22 sont prévues dans la buse 21 de la collerette 18 pour faire communiquer l'intérieur du canal 12 de la cartouche 9 avec un canal annulaire 23 délimité entre le noyau 21 et l'aimant 17. Lights 22 are provided in the nozzle 21 of the collar 18 to communicate the interior of the channel 12 of the cartridge 9 with an annular channel 23 delimited between the core 21 and the magnet 17.

Un capuchon 24 recouvre le noyau 21 sur lequel il est enfilé pour pouvoir coulisser. Le capuchon 24 est également réalisé en une matière magnétique et il délimite un bossage annulaire 25 destiné à coopérer avec un siège 26 supporté par l'aimant 17.  A cap 24 covers the core 21 on which it is threaded in order to be able to slide. The cap 24 is also made of a magnetic material and it delimits an annular boss 25 intended to cooperate with a seat 26 supported by the magnet 17.

Lorsque l'eau ne circule pas, les forces magnétiques exercent une attraction sur la capuchon 24 qui repose sur le siège 26. When the water does not circulate, the magnetic forces exert an attraction on the cap 24 which rests on the seat 26.

Lorsque de l'eau est amenée à circuler dans le dispositif de la manière décrite dans ce qui précède, celle-ci est pré-traitée en passant entre la paroi de la cuve 1 et la périphérie de l'aimant 17, ce qui a pour effet de retenir une grande partie des particules magnétisables qu'elle contient. L'eau passe ensuite à travers la cartouche 9, entre dans le canal 12 et passe par les lumières 22 et le canal annulaire 23 pour être amenée et arriver à l'intérieur de l'entretoise tubulaire 14 la menant à la collerette 16. Ainsi l'eau est amenée a soulever le capuchon 24 de son siège 26. When water is caused to circulate in the device in the manner described in the foregoing, it is pretreated by passing between the wall of the tank 1 and the periphery of the magnet 17, which has the effect of retaining a large part of the magnetizable particles which it contains. The water then passes through the cartridge 9, enters the channel 12 and passes through the openings 22 and the annular channel 23 to be brought and arrive inside the tubular spacer 14 leading it to the collar 16. Thus the water is brought to lift the cap 24 from its seat 26.

La largeur de l'entrefer créé entre le siège 26 et le capuchon 24 dépend du débit d'eau de sorte que la veine d'eau traversant cet entrefer est toujours parcourue par des lignes de force du champ magnétique qui sont évidemment concentrées au niveau de l'entrefer. The width of the air gap created between the seat 26 and the cap 24 depends on the water flow so that the stream of water passing through this air gap is always traversed by lines of force of the magnetic field which are obviously concentrated at the level of the air gap.

Les particules en suspens dans l'eau sont, par conséquent, soumises à l'action d'un champ magnétique intense faisant que lesdites particules n'ont ensuite plus tendance à s'incruster sur la paroi du conduit 8 et des tubes ou autres cavités qui peuvent la prolonger. The particles suspended in the water are therefore subjected to the action of an intense magnetic field such that the said particles then no longer tend to become encrusted on the wall of the duct 8 and of the tubes or other cavities who can extend it.

Les fig. 3 et 4 illustrent une réalisation selon laquelle deux conducteurs 27, 28 disposés dans le canal 23 sont reliés à une source de courant 29 et à un appareil de mesure et de détection 30, par exemple un galvanomètre, des diodes électroluminescentes ou un appareil de mesure de seuil électrique. Figs. 3 and 4 illustrate an embodiment in which two conductors 27, 28 arranged in the channel 23 are connected to a current source 29 and to a measurement and detection device 30, for example a galvanometer, light-emitting diodes or a measurement device electric threshold.

Les indications fournies par l'appareil 30 permettent un contrôle de l'efficacité du traitement magnétique réalisé et aussi de connaltre approximativement la densité de particules en suspension dans le liquide.  The indications provided by the apparatus 30 allow a control of the efficiency of the magnetic treatment carried out and also of approximating the density of particles in suspension in the liquid.

La fig. 3 illustre une variante selon laquelle des ailettes 31, de préférence en forme d'hélice sont disposées à la partie supérieure de la cuve 1, par exemple portées par l'armature 18, pour provoquer une centrifugation des particules solides amenées par l'embout d'entrée 5. Fig. 3 illustrates a variant according to which fins 31, preferably in the form of a helix, are arranged at the upper part of the tank 1, for example carried by the frame 18, to cause centrifugation of the solid particles brought in by the nozzle d 'entry 5.

De cette manière, une partie importante des particules est séparée par effet cyclonique et est amenée à tomber le long de la paroi interne de la cuve 1 vers le fond de celle-ci. In this way, a significant part of the particles is separated by cyclonic effect and is caused to fall along the internal wall of the tank 1 towards the bottom thereof.

Dans cette réalisation, la cartouche 9 est supportée par une coupelle 32 qui la maintient au-dessus du fond du la cuve 1. In this embodiment, the cartridge 9 is supported by a cup 32 which keeps it above the bottom of the tank 1.

La coupelle 32 sert d'appui à un ressort 33 d'un clapet de décolmatage 34 qui ferme normalement une ouverture 35 du fond de la cuve 1. The cup 32 serves as a support for a spring 33 of an unclogging valve 34 which normally closes an opening 35 in the bottom of the tank 1.

Un poussoir 36 permet l'actionnement du clapet 34 pour l'évacuation des boues s'accumulant dans le fond de la cuve 1. A pusher 36 allows actuation of the valve 34 for the evacuation of the sludge accumulating in the bottom of the tank 1.

En outre, dans cette réalisation, la buse 19 porte un noyau 21a qui est creux et dans lequel est vissée une vis 37 sur le dessus de laquelle repose le capuchon 24. Furthermore, in this embodiment, the nozzle 19 carries a core 21a which is hollow and into which is screwed a screw 37 on top of which rests the cap 24.

Dans cette réalisation, l'armature 18 est conformée intérieurement pour que le siège 26 et le bossage annulaire 25 du capuchon délimitent une tuyère par laquelle l'eau est amenée à passer et à subir ainsi un traitement magnéto-hydrodynamique (MHD). In this embodiment, the frame 18 is internally shaped so that the seat 26 and the annular boss 25 of the cap delimit a nozzle through which the water is caused to pass and thus undergo a magneto-hydrodynamic treatment (MHD).

En agissant sur la vis 37, il est possible de régler la position initiale du capuchon 24 pour qu'il existe toujours un entrefer de passage, cela évite qu'une perte de charge importante soit provoquée pour équilibrer la force portante de l'aimant ainsi que cela peut se produire si le capuchon 25 repose sur le siège 26.  By acting on the screw 37, it is possible to adjust the initial position of the cap 24 so that there is always a passage air gap, this avoids that a significant pressure drop is caused to balance the bearing force of the magnet thus that this can happen if the cap 25 rests on the seat 26.

Comme l'illustre le dessin, l'aimant 17 est maintenu par un simple emboîtement entre des portées 38 de la buse 19 et 39 de l'armature 18. As illustrated in the drawing, the magnet 17 is held by a simple interlocking between the bearings 38 of the nozzle 19 and 39 of the frame 18.

De cette manière, au moment du changement de la cartouche 9, après dévissage de la tête distributrice 4 et retrait de l'armature 18, l'aimant 13 peut être retourné pour assurer une inversion de polarité lors du traitement subséquent. In this way, when changing the cartridge 9, after unscrewing the dispensing head 4 and removing the armature 18, the magnet 13 can be turned over to ensure reverse polarity during subsequent processing.

Outre ce qui précède, il est avantageux que la tête 4 soit munie comme représenté, d'un clapet de purge d'air 40. In addition to the above, it is advantageous for the head 4 to be provided, as shown, with an air purge valve 40.

L'invention n'est pas limitée aux exemples de réalisation, représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, l'entretoise tubulaire 14 peut être supprimée lorsque le diamètre interne de la collerette tubulaire 16 est prévu pour permettre le passage du capuchon coulissant 24.  The invention is not limited to the exemplary embodiments, shown and described in detail, since various modifications can be made thereto without departing from its scope. In particular, the tubular spacer 14 can be omitted when the internal diameter of the tubular flange 16 is provided to allow passage of the sliding cap 24.
