Description

Dispositif de filtration et d'évacuation de petites particules, déchets et détritus, de natures diverses. L'invention se rattache au secteur technique des systèmes de filtrations incorporées dans des installations de traitement de l'eau en vue d'un recyclage tout en autorisant une évacuation des déchets collectés. L'invention se rattache également aux secteurs techniques des piscines, des installations de massage corporel, et toutes installations sanitaires.  Device for filtration and evacuation of small particles, waste and detritus, of various kinds. The invention relates to the technical sector of filtration systems incorporated in water treatment installations for recycling while allowing the evacuation of the collected waste. The invention also relates to the technical sectors of swimming pools, body massage installations, and all sanitary installations.
Dans les systèmes de filtration équipant les installations du type précité, il arrive souvent que certaines particules ou déchets s'incrustent aux grilles filtrantes à position fixe, de sorte que leur évacuation n'est possible que par suite d'une intervention manuelle d'un opérateur.  In the filtration systems fitted to installations of the aforementioned type, it often happens that certain particles or waste become encrusted in the filter grates in a fixed position, so that their evacuation is only possible following a manual intervention by a operator.
On a par ailleurs constaté dans certaines applications où les être humains sont en contact avec un environnement d'eau et en particulier dans des cabines de douche, ou de massage avec projection d'eau, que de fines particules de peau se détachent naturellement du corps de l'individu et viennent obturer les grilles précitées, soit également par le fait que la peau pèle naturellement.  It has also been observed in certain applications where human beings are in contact with a water environment and in particular in shower cubicles, or in massage cabins with spray of water, that fine particles of skin naturally detach from the body. of the individual and come to close the aforementioned grids, or also by the fact that the skin peels naturally.
On a constaté également cet inconvénient dans le cas d' opérations de lavage et d' entretien de certaines matières textiles où des bourres se forment et se détachent pour obturer le système de filtration.  This drawback has also been observed in the case of washing and maintenance operations for certain textile materials where fluff forms and becomes detached in order to block the filtration system.
Un premier but selon l'invention était donc de concevoir un dispositif de filtration qui permette, à tous instants, une filtration et une évacuation de tous produits et détritus.  A first object according to the invention was therefore to design a filtration device which allows, at all times, filtration and evacuation of all products and detritus.
Un autre but selon l'invention était de réaliser un dispositif de filtration de conception simple, de montage rapide et adaptable pour tous types d'applications. Un autre but selon l'invention était de réaliser un dispositif pour assurer une séparation des eaux filtrées et propres pouvant être recyclées et du stockage des détritus à évacuer. Another object according to the invention was to provide a filtration device of simple design, quick assembly and adaptable for all types of applications. Another object according to the invention was to provide a device for ensuring separation of the filtered and clean water which can be recycled and the storage of the detritus to be removed.
Ces buts et d'autres encore ressαrtiront bien de la suite de la description.  These aims and others will become clear from the rest of the description.
Selon une première caractéristique, le dispositif comprend une bande sans fin convoyeuse en forme de treillis ou grille assurant la filtration des eaux projetées ou amenées, ladite bande étant animée d'un mouvement de défilement continu en étant positionnée dans une ossature support recevant ses moyens de commande et de guidage, ladite ossature support s'adaptant sur un bac profilé compartimenté réceptionnant d'une part les eaux projetées et filtrées par la bande convoyeuse et d'autre part les détritus et déchets collectés et évacués par ladite bande.  According to a first characteristic, the device comprises an endless conveyor belt in the form of a trellis or grid ensuring the filtration of the projected or supplied water, said band being animated by a continuous movement of scrolling by being positioned in a support frame receiving its means of control and guiding, said support frame adapting to a compartmentalized profiled tank receiving on the one hand the water projected and filtered by the conveyor belt and on the other hand the detritus and waste collected and discharged by said band.
Selon une autre caractéristique, le premier compartiment de volume plus important reçoit l'eau projetée et filtrée par les brins superposés de la bande de convoyage en avant du second compartiment de réception et de collecte des détritus, ledit second compartiment étant sousjacent de la partie d'extrémité de la bande de convoyage.  According to another characteristic, the first compartment of larger volume receives the water projected and filtered by the superimposed strands of the conveyor belt in front of the second compartment for receiving and collecting litter, said second compartment being underlying the part d end of the conveyor belt.
Selon une autre caractéristique, le dispositif comprend entre les brins parallèles supérieur et inférieur de la bande de convoyage dans un plan correspondant sensiblement au-dessus du compartiment de réception des détritus et autres déchets, une rampe de distribution de fluide exerçant une force ou poussée vers le fond du bac pour le détachement des particules et détritus, ladite rampe étant associée à une source d'alimentation de fluide appropriée.  According to another characteristic, the device comprises between the upper and lower parallel strands of the conveyor belt in a corresponding plane substantially above the detritus and other waste reception compartment, a fluid distribution ramp exerting a force or push towards the bottom of the tank for detaching particles and detritus, said ramp being associated with a suitable fluid supply source.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.  These characteristics and others will become apparent from the following description.
Pour fixer l'objet de l'invention illustrée d'une manière non limitative aux figures des dessins où : La figure 1 est une vue du dispositif de filtration en une perspective éclatée montrant son principe de fonctionnement. To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings where: Figure 1 is a view of the filtration device in an exploded perspective showing its operating principle.
La figure 2 est une vue à caractère schématique illustrant le dispositif de filtration intégré dans une installation.  Figure 2 is a schematic view illustrating the filtration device integrated in an installation.
La figure 3 est une vue en coupe transversale selon la ligne A-A de la figure 1.  Figure 3 is a cross-sectional view along line A-A of Figure 1.
La figure 4 est une vue à caractère schématique illustrant l'application du dispositif selon l'invention dans une installation de massage corporel par hydrothérapie.  Figure 4 is a schematic view illustrating the application of the device according to the invention in a body massage installation by hydrotherapy.
Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation des figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.
Le dispositif de filtation comprend, selon l'invention, une bande convoyeuse (1) en forme de treillis ou grille assurant sa filtration constituant une bande sans fin autour d'un rouleau ou tambour meneur (2) et un rouleau mené (3). L'écartement desdits rouleaux est fonction de la longueur de la bande convoyeuse en fonction de l'application considérée et peut être adaptée et réglée de manière connue avec éventuellement un dispositif de mise sous tension et de réglage de la bande convoyeuse. Les rouleaux (2) (3) sont fixés de toutes manières appropriées par rapport à une ossature support (4) profilée formant avantageusement caisson de réception de la bande convoyeuse (1). Ce rouleau ou tambour meneur (2) est alimenté par un groupe moteur (5) approprié fixé sur une paroi ou profil du caisson de réception du convoyeur. Ledit caisson est avantageusement positionné et centré sur un bac (6) réalisé de forme périphérique complémentaire, et agencé avec une bordure périphérique support et définissant un volume parallèle pipédique. Ce bac comprend selon l'invention, deux compartiments (6.1 - 6.2) séparés à étanchéité par un cloisonnement (6.3) approprié. Les deux compartiments sont de volume différent mais chacun étant en relation directe avec une partie plus ou moins grande de la bande de convoyage. The filtration device comprises, according to the invention, a conveyor belt (1) in the form of a trellis or grid ensuring its filtration constituting an endless band around a roller or driving drum (2) and a driven roller (3). The spacing of said rollers is a function of the length of the conveyor belt as a function of the application considered and can be adapted and adjusted in known manner with optionally a device for tensioning and adjusting the conveyor belt. The rollers (2) (3) are fixed in any suitable manner with respect to a profiled support frame (4) advantageously forming a box for receiving the conveyor belt (1). This roller or driving drum (2) is supplied by an appropriate motor group (5) fixed to a wall or profile of the receiving box of the conveyor. Said box is advantageously positioned and centered on a tank (6) made of complementary peripheral shape, and arranged with a peripheral support border and defining a parallel volume pipedic. According to the invention, this container comprises two compartments (6.1 - 6.2) separated by a suitable partition (6.3) for sealing. The two compartments are of different volume but each being in direct relation with a more or less large part of the conveyor belt.
Plus particulièrement, un premier compartiment de volume plus important reçoit l'eau projetée et filtrée par les deux brins superposés de la bande de convoyage. Les projections ou écoulement d'eau venant en amont et au-dessus du dispositif de filtration ne s'effectuent avantageusement que sur la partie de bande en regard dudit compartiment (6.1). L'autre compartiment (6.2) adjacent est en regard sousjacent de la partie d'extrémité de la bande de convoyage et est de préférence protégé de toute projection d'eau par une paroi, couvercle ou autre, solidaire de l'ossature-support. Ce compartiment (6.2) est destiné à collecter les détritus susceptibles d'être retenus par la bande formée en treillis ou grillage. Le sens de défilement selon la flècheF permet d'identifier l'avancement sans fin et continu de la bande amenant ainsi d'une zone (A) les détritus tombant sur la grille ou treillis au-dessus du premier compartiment (6.1) vers une zone (B) au-dessus du second compartiment (6.2). Au cours de l'enroulement de la bande et notamment son passage autour du rouleau moteur (2), les particules ou détritus doivent naturellement tomber par simple gravité dans le bac collecteur (6.2). Afin de faciliter le détachement de particules ou détritus qui pourraient être collés à la bande de convoyage sous forme de treillis ou grille, on dispose transversalement entre les brins supérieur et inférieur de la bande et au-dessus du réceptacle collecteur et détritus au moins une rampe (7) de distribution de fluide susceptible d'exercer une force ou pousser vers le bord du bac (6.2) constituant un détachementdesdites particules. Cette rampe présente une pluralité d'ouvertures recevant ou non des buses de projection de fluide orientées vers le brin inférieur pour balayer la bande de convoyage dans un plan transversal sur une certaine largeur. Le fluide peut être de l'eau ou de l'air comprimé, avec une source More particularly, a first compartment of larger volume receives the water projected and filtered by the two superimposed strands of the conveyor belt. The projections or flow of water coming upstream and above the filtration device advantageously take place only on the part of the strip opposite said compartment (6.1). The other adjacent compartment (6.2) is opposite the end portion of the conveyor belt and is preferably protected from any splashing of water by a wall, cover or the like, integral with the support frame. This compartment (6.2) is intended to collect the detritus likely to be retained by the strip formed in lattice or grating. The direction of scrolling according to arrow F makes it possible to identify the endless and continuous advancement of the strip thus bringing from a zone (A) the detritus falling on the grid or trellis above the first compartment (6.1) towards a zone (B) above the second compartment (6.2). During the winding of the strip and in particular its passage around the driving roller (2), the particles or detritus must naturally fall by simple gravity into the collecting tank (6.2). In order to facilitate the detachment of particles or detritus which could be stuck to the conveyor belt in the form of a trellis or grid, at least one ramp is disposed between the upper and lower strands of the band and above the collecting receptacle and detritus (7) distributing fluid capable of exerting a force or pushing towards the edge of the tank (6.2) constituting a detachment of said particles. This ramp has a plurality openings receiving or not receiving fluid spray nozzles oriented towards the lower strand to sweep the conveyor belt in a transverse plane over a certain width. The fluid can be water or compressed air, with a source
d'alimentation appropriée. proper feeding.
Selon une variante de réalisation, les ouvertures ou rampes de fluide peuvent être orientées en direction du haut du rouleau (2) équipé d'au moins une turbine (9) (traits interrompus, figure 3), afin d'entraîner ledit rouleau en rotation en lieu et place du moteur.  According to an alternative embodiment, the openings or ramps of fluid can be oriented in the direction of the top of the roller (2) equipped with at least one turbine (9) (broken lines, Figure 3), in order to drive said roller in rotation in place of the engine.
On comprend ainsi que la bande de convoyage est constamment nettoyée lors de son défilement en continu.  It is thus understood that the conveyor belt is constantly cleaned during its continuous scrolling.
Selon une disposition complémentaire, il est possible de coupler par des moyens appropriés le fonctionnement de distribution de fluide par la rampe (7) avec le défilement de la bande. Accessoirement, le compartiment collecteur (6.2) de détritus peut présenter une porte d'accès ou moyen similaire pour prélever et évacuer les détritus collectés en assurant un nettoyage.  According to an additional arrangement, it is possible to couple, by appropriate means, the fluid distribution operation by the ramp (7) with the running of the strip. Incidentally, the trash collecting compartment (6.2) may have an access door or similar means for collecting and removing the collected trash while ensuring cleaning.
Par ailleurs, l'eau qui a été filtrée par la bande (1) peut être recyclée avec tous moyens techniques correspondants connus de l'homme de l'art avec, si besoin, adjonction d'eau supplémentaire. En fonction du mode d'utilisation du dispositif de filtration selon l'invention et dans son application à une cabine de douche ou de massage, il est possible de commander le fonctionnement de la bande de convoyage avec la commande de projection d'eau. On a illustré, figure 4, un exemple d'application non limitatif du dispositif de filtration à une cabine de massage. Celle-ci peut être du type de celle décrite dans la Demande de Brevet français Nº 88.14516, au nom de certains des déposants de la présente Demande.  Furthermore, the water which has been filtered by the strip (1) can be recycled with any corresponding technical means known to those skilled in the art, with the addition of additional water if necessary. Depending on the mode of use of the filtration device according to the invention and in its application to a shower or massage cabin, it is possible to control the operation of the conveyor belt with the water spraying control. Illustrated, Figure 4, an example of non-limiting application of the filtration device to a massage cabin. This may be of the type described in French Patent Application No. 88.14516, in the name of some of the applicants for this Application.
Il y a lieu par ailleurs d'observer que l'utilisateur n'est pas en contact avec la bande de convoyage . It should also be noted that the user is not in contact with the tape. conveying.
L'invention groupe de multiples autres applications et utilisations telles que pour les piscines, bains publics, installations thermales, traitement de matériaux ...., matières textiles et autres.  The invention groups multiple other applications and uses such as for swimming pools, public baths, thermal installations, treatment of materials, textile materials and others.
Dans ce cas d'utilisation, le caisson est fermé sur le dessus et présente une arivée d'eau à recycler située au-dessus de la bande convoyeuse du côté du rouleau meré. avantages ressortent bien de l'invention. En particulier, on souligne :  In this case of use, the box is closed on the top and has an inlet for recycling water located above the conveyor belt on the side of the meré roller. advantages clearly emerge from the invention. In particular, we emphasize:
- la simplicité du dispositif de filtration et son faible coût de revient. En outre, il est possible de le réaliser sous forme de kit d'assemblage avec d'une part un bac compartimenté recevant dans sa partie supérieure une ossature ou encadrement support du mécanisme.  - the simplicity of the filtration device and its low cost price. In addition, it is possible to produce it in the form of an assembly kit with on the one hand a compartmentalized container receiving in its upper part a framework or support frame for the mechanism.
Le dispositif peut être réalisé en toutes dimensions et volumes pour s'adapter a toutes applications.  The device can be produced in all dimensions and volumes to adapt to all applications.
