Abstract

The invention concerns a device for sequential flushing and distributing liquid independently of liquid storage tanks, characterised in that it comprises preferably a hydrostatic connection (1), a hollow mobile arm (2) equipped or not with a pressure regulating valve, adjustable between a low position called flushing position and a high position called quiescent position, the mobility being provided by a balance differential between the high position by counterweight effect (3) and the hydrostatic flushing of the flushing arm and by the overflow of the ballast reservoir capable of being flushed (4) displacing the centre of gravity, while maintaining the tilting by controlled lever effect, in one or several final flushing position. Said hydraulic device preferably independent of any source of electricity generation is particularly adapted for feeding biological filters for purifying effluents and irrigation.

Description

DISPOSITIF DE VIDANGE SEQUENTIELLE ET DE DISTRIBUTION DE LIQUIDEDEVICE FOR SEQUENTIAL DRAINING AND DISPENSING LIQUID
La présente invention concerne un dispositif de vidange séquentielle et de distribution de liquide, indépendant d'un réservoir de stockage ou de transit, pour l'envoi de volumes maîtrisés et réglables de liquides vers une ou plusieurs aires d'épandage, à vocation de traitement des eaux ou d'irrigation notamment.The present invention relates to a sequential emptying and liquid distribution device, independent of a storage or transit tank, for sending controlled and adjustable volumes of liquids to one or more spreading areas, intended for treatment. water or irrigation in particular.
Les moyens actuels décrits dans la littérature spécialisée et illustrés dans les brevets de SIMON ANDRE et WAVIN, respectivement 97 02315 etThe current means described in the specialized literature and illustrated in the patents of SIMON ANDRE and WAVIN, respectively 97 02315 and
89 15352, n'apportent pas la souplesse d'utilisation nécessaire quant au réglage du marnage ou à l'indépendance et moyens de réglage de la mobilité du bras de vidange.89 15352, do not provide the flexibility of use necessary for adjusting the tidal range or the independence and means of adjusting the mobility of the drain arm.
La présente invention a donc pour objet principal de remédier à ces inconvénients, en désolidarisant le bras de chasse du réservoir amont, simple ou multiple, par un moyen de liaison quelconque, la mobilité du bras entre deux positions étant déclenchée en particulier par le remplissage par trop plein d'un ballast vidangeable solidaire du bras, entraînant le déplacement le centre de gravité. De préférence le bras de vidange est équipé d'un contre poids réglable, les positions du bras haute et basse étant assurées par calage et d'un réservoir ballast solidaire du bras et à capacité réglable et alimenté librement, à partir d'une cote de référence, par une canalisation réglable de trop plein, active en position de marnage haut du réservoir. Dans une application particulière, le bras de vidange plus ou moins long est muni d'un clapet de nez plus ou moins lesté qui est libéré en position basse, mécaniquement par un taquet, permettant un surmarnage pression, au delà de la cote de vidange du bras.The main object of the present invention is therefore to remedy these drawbacks, by separating the flushing arm from the upstream tank, single or multiple, by any connecting means, the mobility of the arm between two positions being triggered in particular by filling with too full of a drainable ballast secured to the arm, causing the center of gravity to move. Preferably the emptying arm is equipped with an adjustable counterweight, the positions of the upper and lower arm being ensured by wedging and of a ballast tank secured to the arm and with adjustable capacity and supplied freely, from a dimension of reference, by an adjustable overflow pipe, active in the tank top position. In a particular application, the more or less long emptying arm is provided with a more or less weighted nose valve which is released in the low position, mechanically by a cleat, allowing a pressure boost, beyond the emptying dimension of the arms.
Dans une autre application particulière, l'extrémité du bras est articulé, pour venir prendre appui alternativement de chaque coté de plateaux de balance, séparé par une pointe escamoteuse.In another particular application, the end of the arm is articulated, to come to bear alternately on each side of weighing plates, separated by a retractable tip.
Des modèles principaux d'exécution sont décrits et illustrés ci-après, à titre d'exemple :Main execution models are described and illustrated below, by way of example:
- La figure 1 est une vue en coupe du dispositif de vidange séquentiel, illustrant les principaux composants,FIG. 1 is a sectional view of the sequential emptying device, illustrating the main components,
- La figure 2 simule le fonctionnement hydraulique du dispositif, dans deux positions, active et au repos. - La figure 3 est une variante avec clapet,- Figure 2 simulates the hydraulic operation of the device, in two positions, active and at rest. - Figure 3 is a variant with valve,
- La figure 4 est une variante avec répartition alternée.- Figure 4 is a variant with alternating distribution.
Le dispositif selon l'invention ( fig. 1 ) se caractérise par un lien hydraulique (1) communiquant avec au moins un réservoir et un bras creux mobile (2) positionné sur cale réglable au repos par un contrepoids (3) et solidaire d'un réservoir ballast dynamique vidangeable (4) alimenté par un trop plein (5) faisant basculer le bras, articulé ou non, vers une ou plusieurs positions de vidange (6). Lorsque le niveau de liquide est en position haute dans le réservoir et le bras de vidange et pour un angle déterminé ( figure 2 ), le trop plein alimenté à un débit maîtrisé se déverse (7) dans le réservoir ballast qui annule progressivement le contrepoids et fit basculer le bras à débit maîtrisé par masque réglable (8). Dans cette position basse, le ballast se vidange pour préparer la position retour haute, en parallèle de la vidange du réservoir amont, le bras étant maintenu en position horizontale par effet levier poids supérieur à la force du contrepoids, jusqu'à l'arrêt de l'écoulement en position basse de marnage du réservoir amont. Dans la variante à clapet (9) tout ou rien (figure 3 ), le bras est court (10), lesté pour régler le marnage utile, l'ouverture se faisant en position basse par taquet (11).The device according to the invention (fig. 1) is characterized by a hydraulic link (1) communicating with at least one reservoir and a movable hollow arm (2) positioned on an adjustable wedge at rest by a counterweight (3) and integral with a dynamic drainable ballast tank (4) supplied by an overflow (5) causing the arm, tilted or not, to tilt to one or more drain positions (6). When the liquid level is in the high position in the tank and the emptying arm and for a determined angle (figure 2), the overflow supplied at a controlled flow flows (7) into the ballast tank which gradually cancels the counterweight and tilted the arm with controlled flow by adjustable mask (8). In this low position, the ballast empties to prepare the high return position, in parallel with the emptying of the upstream tank, the arm being held in a horizontal position by lever effect, weight greater than the force of the counterweight, until the stop the flow in the low tidal position of the upstream reservoir. In the all-or-nothing valve variant (9) (FIG. 3), the arm is short (10), ballasted to adjust the useful drawdown, the opening being made in the low position by cleat (11).
Dans la variante à distribution ( figure 4 )dans plusieurs directions, à chaque cycle de vidange, la balance (12) positionne alternativement le bras à droite ou à gauche. L'ensemble du dispositif est réalisable en majorité à partir de composants standards, à dominante plastique, l'axe creux rotatif étant réalisé par exemple à partir d'une bride modifiée et un joint tournant spécifique résistant à de nombreux cycles et autres agressions du milieu. De nombreux réglages sont rendus possibles par positionnement de petits accessoires métalliques, mamages et débits, liens bras contrepoids par fil et poulies par exemple, raccord rapide pour lien entre bras actif et réservoir amont. In the variant with distribution (FIG. 4) in several directions, at each emptying cycle, the balance (12) alternately positions the arm to the right or to the left. Most of the device can be produced using standard components, predominantly plastic, the hollow rotary axis being produced, for example, from a modified flange and a specific rotary joint resistant to many cycles and other environmental attacks. . Many adjustments are made possible by positioning small metal accessories, mamages and flow rates, counterweight arm links by wire and pulleys for example, quick coupling for link between active arm and upstream tank.
