Description
La présente invention concerne un dispositif de filtration pour piscine.The present invention relates to a filtration device for swimming pools.
te problème de la filtration de l'eau des piscines n'a pas reçu jusqu'à présent de solution satisfaisante. Les dispositifs actuellement connus sont généralement complexes et leur entretien est difficile
De nombreux dispositifs de filtration ont été proposés. Le document FR 2 336.965, par exemple, décrit un dispositif de filtration comportant un panier perforé placé à l'intérieur d'une chambre. I,e fluide qui doit être filtré circule à l'intérieur de cette chambre depuis un orifice d'entrée jusqu'à un orifice de sortie en traversant le panier qui assure la filtration. Le panier peut être extrait de la chambre pour être nettoyé.The problem of swimming pool water filtration has so far not received a satisfactory solution. Currently known devices are generally complex and their maintenance is difficult.
Many filtration devices have been proposed. The document FR 2 336 965, for example, describes a filtration device comprising a perforated basket placed inside a chamber. I, e fluid which must be filtered circulates inside this chamber from an inlet orifice to an outlet orifice through the basket which ensures filtration. The basket can be removed from the room for cleaning.
On a également proposé1 par exemple dans le document FR 1.454.470, un filtre pour piscine dans lequel l'élément filtrant est constitué par un manchon en mousse plastique qui est disposé sur un support tubulaire perforé. L'eau qui doit être filtrée est admise dans un espace annulaire entourant le manchon et extraite par le support tubulaire perforé.We have also proposed1 for example in document FR 1,454,470, a swimming pool filter in which the filter element is constituted by a plastic foam sleeve which is disposed on a perforated tubular support. The water to be filtered is admitted into an annular space surrounding the sleeve and extracted through the perforated tubular support.
tors de la conception de tels dispositifs, le choix de la porosité de l'élément filtrant fait l'objet d'un compromis : des pores de petite dimension conduisent à un colmatage rapide de l'élément filtrant, alors que des pores de dimension plus importante ne permettent pas d'assurer une qualité satisfaisante de la filtration.When designing such devices, the choice of the porosity of the filter element is the subject of a compromise: small pores lead to rapid clogging of the filter element, while pores of more dimension important do not ensure a satisfactory quality of filtration.
On connaît également de nombreux dispositifs de filtration dans lesquels l'élément filtrant est un filtre en papier jetable. Ile coût d'exploitation de ces dispositifs de filtration est alors très élevé.Numerous filtration devices are also known in which the filter element is a disposable paper filter. The operating cost of these filtration devices is therefore very high.
te but de la présente invention est donc de proposer un dispositif de filtration permettant une filtration efficace dont la manipulation soit simple et ltentretien peu coûteux. The object of the present invention is therefore to propose a filtration device allowing efficient filtration, the handling of which is simple and maintenance inexpensive.
A cet effet, l'invention concerne un dispositif de filtration pour piscine du type comprenant un boîtier ouvrable et un filtre, le boîtier comportant un orifice d'admission, un orifice de sortie, le filtre étant placé à l'intérieur du boîtier et devant être traversé par un liquide circulant sous l'effet d'une pompe depuis l'orifice d'admission vers l'orifice de sortie. Le boîtier et le filtre sont de forme allongée, approximativement cylindrique ou tronconique, destinés à être utilisés en position approximativement verticale.To this end, the invention relates to a filtration device for a swimming pool of the type comprising an opening housing and a filter, the housing comprising an inlet orifice, an outlet orifice, the filter being placed inside the housing and in front be crossed by a liquid circulating under the effect of a pump from the inlet port to the outlet port. The housing and the filter are elongated, approximately cylindrical or frustoconical, intended to be used in approximately vertical position.
Selon l'invention, le filtre est souple et a une forme de poche, la périphérie de l'ouverture de la dite poche étant fixée au boîtier1 l'orifice d'admission étant situé au-dessus de la dite ouverture et l'orifice de sortie étant situé en-dessous de la dite ouverture. Il comporte un support de forme allongée approximativement cylindrique ou tronconique fixe par rapport au boîtier, contenant le filtre qui s'appuie sur ses parois lors du fonctionnement du dispositif. Le support de forme est perforé et distant du boîtier de manière à autoriser la circulation du liquide ayant traversé le filtre vers l'orifice de sortie.According to the invention, the filter is flexible and has a pocket shape, the periphery of the opening of said pocket being fixed to the housing1 the inlet opening being located above said opening and the opening of outlet being located below said opening. It comprises a support of elongated shape approximately cylindrical or frustoconical fixed relative to the housing, containing the filter which is supported on its walls during the operation of the device. The form support is perforated and distant from the housing so as to allow the circulation of the liquid having passed through the filter towards the outlet orifice.
L'invention sera décrite en détail en référence aux dessins annexes dans lesquels - ta figure 1 est une représentation schématique d'une coupe verticale
A-A du dispositif de filtration de l'invention.The invention will be described in detail with reference to the accompanying drawings in which - your Figure 1 is a schematic representation of a vertical section
AA of the filtration device of the invention.
- ta figure 2 est une représentation schématique d'une coupe
horizontale partielle B-B du dispositif de filtration de
l'invention.- your figure 2 is a schematic representation of a section
partial horizontal BB of the filtration device
the invention.
Le dispositif de filtration comporte un boîtier ouvrable 1 contenant un filtre 2. Le boîtier est constitué d'un corps 3 fermé par un couvercle amovible 4. L'étanchéité de la jonction entre le corps 3 et le couvercle 4 est assurée par exemple par un joint torique 5. La fixation du couvercle 4 sur le corps 3 peut être réalisée par tout moyen tel que des vis, mais de préférence elle est obtenue par la coopération de fixations élastiques à clips 6 fixées sur le couvercle avec des protubérances 7 portées par la surface extérieure du corps 3 du boîtier L'ouverture du corps 3 dégagée en absence de couvercle est adaptée et suffisante pour permettre l'extraction des différents éléments contenus par le boîtier.The filtration device comprises an openable housing 1 containing a filter 2. The housing consists of a body 3 closed by a removable cover 4. The seal of the junction between the body 3 and the cover 4 is ensured for example by a O-ring 5. The fixing of the cover 4 to the body 3 can be carried out by any means such as screws, but preferably it is obtained by the cooperation of elastic fasteners with clips 6 fixed on the cover with protuberances 7 carried by the outer surface of the body 3 of the housing The opening of the body 3 released in the absence of a cover is suitable and sufficient to allow the extraction of the various elements contained by the housing.
Le boîtier a une forme générale tant intérieure qu' extérieure allongée, approximativement cylindrique ou tronconique. il est destiné à être utilisé en position approximativement verticale. The housing has a general shape both inside and outside elongated, approximately cylindrical or frustoconical. it is intended to be used in an approximately vertical position.
A sa partie supérieure latérale, il comporte un orifice d'admission 8 et à sa partie inférieure, un orifice de sortie 9.At its upper lateral part, it has an inlet port 8 and at its lower part, an outlet port 9.
te filtre 2 est souple et a une forme de poche. On entend ici par "forme de poche", une forme allongée, comportant donc une paroi latérale approximativement cylindrique ou tronconique fermée à l'une de ses extrémités et ouverte à l'autre.filter 2 is flexible and has a pocket shape. The term “pocket shape” is understood here to mean an elongated shape, therefore comprising an approximately cylindrical or frustoconical side wall closed at one of its ends and open to the other.
Ce filtre 2 est fixé au boitier 3 le long d'une ligne périphérique 10 de son ouverture 11. L'orifice d'entrée 8 du liquide est située au-dessus de l'ouverture Il du filtre et l'orifice de sortie 9 est situé en-dessous de cette même ouverture 11. La liaison entre le boîtier 3 et le filtre 2 est continue de telle sorte que le liquide ne peut transiter de l'orifice d'admission 8 jusqu'à l'orifice de sortie 9 qu'en traversant le filtre 2.This filter 2 is fixed to the housing 3 along a peripheral line 10 of its opening 11. The inlet port 8 of the liquid is located above the opening Il of the filter and the outlet port 9 is located below this same opening 11. The connection between the housing 3 and the filter 2 is continuous so that the liquid can only pass from the inlet orifice 8 to the outlet orifice 9 only crossing the filter 2.
De manière préférée, le boîtier 3 comporte un épaulement intérieur 12 s'étendant sur tout son pourtour. Cet épaulement 12 comporte une gorge 13 de section approximativement circulaire. Cette gorge 13 coopère avec un jonc en matière plastique ou en acier inoxydable 14, de manière à assurer le coincement du filtre 2 à proximité de son ouverture contre le boîtier 3. Ainsi est réalisée une jonction continue, étanche et amovible entre le boîtier 3 et le filtre 2.Preferably, the housing 3 has an internal shoulder 12 extending over its entire periphery. This shoulder 12 has a groove 13 of approximately circular section. This groove 13 cooperates with a plastic or stainless steel rod 14, so as to secure the filter 2 near its opening against the housing 3. Thus a continuous, sealed and removable junction is made between the housing 3 and filter 2.
Afin de faciliter la fabrication du corps 3 du filtre l'épaulement 12 comme le support du filtre torique 5 peut être constitué d'un élément de forme annulaire rapporté à l'intérieur du cylindre qui constitue la surface principale du boîtier.In order to facilitate the manufacture of the body 3 of the filter, the shoulder 12, like the support of the toric filter 5, may consist of an annular element attached to the inside of the cylinder which constitutes the main surface of the housing.
Un support 15, également de forme allongée approximativement cylindrique ou tronconique, fixe par rapport au boîtier 3r contient le filtre 2. Ce support est perforé et maintenu à une certaine distance de la paroi latérale 16 du corps 3 de manière à permettre la libre circulation du liquide ayant traversé le filtre 2 vers 3 'orifice de sortie 9.A support 15, also of approximately cylindrical or frustoconical elongated shape, fixed relative to the housing 3r contains the filter 2. This support is perforated and kept at a certain distance from the side wall 16 of the body 3 so as to allow the free circulation of the liquid having passed through filter 2 to 3 'outlet 9.
Ce support 15 peut par exemple être réalisé par une grille rigide en matière plastique. il est ouvert à sa partie inférieure comme à sa partie supérieure. Il repose sur le fond 17 du boîtier. Son diamètre extérieur au niveau de l'épaulement 12 est égal au diamètre intérieur de celui-ci. Ainsi, l'épaulement 12 assure le maintien et le centrage du support 15.This support 15 can for example be produced by a rigid plastic grid. it is open at its lower part as at its upper part. It rests on the bottom 17 of the housing. Its outside diameter at the shoulder 12 is equal to the inside diameter thereof. Thus, the shoulder 12 maintains and centers the support 15.
Dans un autre mode de réalisation, le boîtier 1 comporte des nervures portées par ses parois intérieures et assurant le maintien du support 15 à une certaine distance des dites parois.In another embodiment, the housing 1 has ribs carried by its interior walls and ensuring that the support 15 is kept at a certain distance from said walls.
De préférence, un préfiltre 18 de forme approximativement cylindrique ou tronconique est placé à l'intérieur du filtre 2. La partie supérieure 19 du préfiltre 18 est rigide ou semi-rigide et comporte un rebord 20 destiné à s'appliquer sur l'épaulement 12 du corps 3 au-dessus du filtre 2. Cette partie supérieure 19 est cylindrique de même axe que le corps 3 et s'étend, depuis le rebord 20 jusqu'à la face inférieure du couvercle 4 lorsque le boîtier 1 est fermé.Preferably, a prefilter 18 of approximately cylindrical or frustoconical shape is placed inside the filter 2. The upper part 19 of the prefilter 18 is rigid or semi-rigid and has a flange 20 intended to be applied on the shoulder 12 of the body 3 above the filter 2. This upper part 19 is cylindrical with the same axis as the body 3 and extends from the rim 20 to the underside of the cover 4 when the housing 1 is closed.
Ainsi lors de la fermeture du boîtier 1, le couvercle 4 produit l'application du rebord 20 contre l'épaulement 12 et le joint 14 et donc le maintien du préfiltre 18.Thus when the housing 1 is closed, the cover 4 produces the application of the rim 20 against the shoulder 12 and the seal 14 and therefore the maintenance of the prefilter 18.
Dans un mode de réalisation préféré, le couvercle 4 du boîtier 1 comporte une tige centrale 21 rapportée sur celui-ci qui traverse le préfiltre 18, par une ouverture 21 ajustée prévue à cet effet, et vient en appui sur le fond du filtre 2 lorsque le couvercle 4 est en position de fermeture par rapport au corps 3 du boîtier 1. Cette tige centrale 21 assure donc le maintien mécanique du filtre 2 par rapport au support 15 et donc par rapport au corps 3. In a preferred embodiment, the cover 4 of the housing 1 has a central rod 21 attached to it which passes through the prefilter 18, through an adjusted opening 21 provided for this purpose, and comes to bear on the bottom of the filter 2 when the cover 4 is in the closed position relative to the body 3 of the housing 1. This central rod 21 therefore ensures the mechanical retention of the filter 2 relative to the support 15 and therefore relative to the body 3.
Le filtre 2 est avantageusement réalisé dans un textile en nylon qui a des pores dont la dimension est comprise entre 15 et SOp. The filter 2 is advantageously made of a nylon textile which has pores whose dimension is between 15 and SOp.
Le préfiltre a des pores dont la dimension est de l'ordre de 3top. il peut également être réalisé dans un textile en nylon, il peut également être réalisé en acier inox. Dans un mode de réalisation donnant satisfaction, le filtre a un diamètre de 250mm et sa longueur est d'environ 500mm. Sa partie supérieure située située au-dessus de l'épaulement 12 est rigide.The prefilter has pores whose dimension is of the order of 3top. it can also be made of nylon textile, it can also be made of stainless steel. In a satisfactory embodiment, the filter has a diameter of 250mm and its length is approximately 500mm. Its upper part located above the shoulder 12 is rigid.
Lors de la circulation du liquide depuis l'orifice d'entrée 8 vers l'orifice de sortie 9, celui-ci traverse donc successivement le préfiltre 18 puis le filtre 2. La présence du préfiltre 18 évite un colmatage rapide du filtre 2.During the circulation of the liquid from the inlet orifice 8 to the outlet orifice 9, the latter therefore successively passes through the prefilter 18 then the filter 2. The presence of the prefilter 18 prevents rapid clogging of the filter 2.
te support 15 assure le maintien du filtre 2 et évite sa déformation même lorsque celui-ci est soumis à des pressions relativement élevées.the support 15 ensures the maintenance of the filter 2 and prevents its deformation even when the latter is subjected to relatively high pressures.
Le dispositif de filtration comporte avantageusement un manomètre 22 indiquant la pression de l'eau à l'intérieur du boîtier 1, ce qui de manière en soi connue est une indication du degré de colmatage ou d'encrassement du filtre.The filtration device advantageously comprises a pressure gauge 22 indicating the pressure of the water inside the housing 1, which in known manner is an indication of the degree of clogging or clogging of the filter.
Un nettoyage rapide du dispositif de filtration de l'invention peut être obtenu en inversant le sens de circulation du liquide. Ainsi, les impuretés sont alors entraînées par le fluide circulant de l'orifice 9 vers l'orifice 8. La tige centrale maintient alors déployés le filtre et le préfiltre. Lorsqu'un nettoyage complet du dispositif est nécessaire, celui-ci peut être très aisément réalisé. Après ouverture du boîtier 1, le filtre et le préfiltre sont sortis et séparés. Le filtre peut alors être nettoyé par tout moyen, sa structure textile rendant son nettoyage particulièrement simple. Il peut par exemple être mis dans une machine à laver. Après nettoyage, les différents éléments sont remis en place dans la position indiquée plus haut. Le dispositif de filtration de l'invention est donc un dispositif fiable, d'entretien facile et peu coûteux. Les déformations du filtre étant évitées, celui-ci ne risque pas d'être endommagé et a donc une durée de vie très longue. Rapid cleaning of the filtration device of the invention can be obtained by reversing the direction of circulation of the liquid. Thus, the impurities are then entrained by the fluid flowing from the orifice 9 towards the orifice 8. The central rod then keeps the filter and the pre-filter deployed. When a complete cleaning of the device is necessary, it can be very easily carried out. After opening the housing 1, the filter and the prefilter are removed and separated. The filter can then be cleaned by any means, its textile structure making cleaning particularly simple. It can for example be put in a washing machine. After cleaning, the various elements are replaced in the position indicated above. The filtration device of the invention is therefore a reliable device, easy to maintain and inexpensive. The deformations of the filter being avoided, it does not risk being damaged and therefore has a very long service life.
