Les dessins annexés illustrent l'invention : The accompanying drawings illustrate the invention:
La figure 1 représente en coupe, le dispositif de l'invention. 30 La figure 2 représente en la vue dessus une disposition parmi d'autres des buses d'injection sur le plateau de pressage Figure 1 shows in section, the device of the invention. FIG. 2 is a top view of one of a number of injection nozzles on the press plate.
En référence à ces dessins, le dispositif de pressage et déshydratation des boues se compose : d'un châssis(6)(FIGI) sur lequel est monté un vérin hydraulique ou pneumatique vertical (5)(FIGI), pour système hydraulique => moteur électrique, centrale hydraulique, manomètre, électrovanne, nourrice d'air, boitier de commande électro pneumatique. 40 Une plaque de pression supérieure (plateau de pressage) est fixée sur le piston du vérin de pression, l'ensemble automatisé il permet un pressage régulé des boues. Sur cette plaque de pression un dispositif de déshydratation a été intégré, la déshydratation des boues se fait par 45 l'injection d'air sec froid ou chaud dans les boues. - Une cage métallique réalisée à partir d'une tôle inox perforée (ayant des trous de 3 à 5 mm de passage du fluide .Dans cette cage, sont placées à l'intérieur des boues contenues dans des poches ou big-bag filtrants, ces 35 poches ou big bag filtrants peuvent être jupées directement à l'intérieur de la cage. Cela dépendant du dispositif en amont. La cage perforée est adaptée sur un bassin de réception (servant de plaque de contre-pression inférieure) Un bassin de réception placé de façon à faire face à la plaque de pression supérieure coulissant dans la cage inox. il peut être plein avec une vidange ou en tôle perforée. With reference to these drawings, the device for pressing and dewatering sludge consists of: a frame (6) (FIGI) on which is mounted a vertical hydraulic or pneumatic cylinder (5) (FIGI), for hydraulic system => motor electric, hydraulic power station, manometer, solenoid valve, air nipple, electro pneumatic control box. 40 An upper pressure plate (pressure plate) is attached to the piston of the pressure cylinder, the automated assembly allows controlled pressing of the sludge.

10 Principe de Fonctionnement 10 Principle of Operation
Action du vérin par système hydraulique. Cylinder action by hydraulic system.
Après avoir réglé la pression de travail au boitier de commande (4) le moteur 15 électrique actionne les pompes hydrauliques qui envoient de l'huile dans le vérin, actionnant ainsi la descente du piston donc du plateau de pressage. Celui-ci descend à l'intérieur de la cage en pressant les boues, simultanément à la descente du plateau de pressage, l'air comprimé est envoyé dans les buses pour être injecté directement dans les boues. 20 La machine étant pourvue de deux manomètres (pression Huile pression Air) qui permettent de régler instantanément chaque pression de travail.par l'opérateur à tout moment si nécessaire. After having adjusted the working pressure to the control box (4), the electric motor actuates the hydraulic pumps which send oil into the cylinder, thus actuating the lowering of the piston and therefore of the pressing plate. This goes down inside the cage by pressing the sludge, simultaneously with the descent of the pressing plate, the compressed air is sent into the nozzles to be injected directly into the sludge. 20 The machine is equipped with two pressure gauges (Air pressure oil pressure) which allow to instantly adjust each working pressure by the operator at any time if necessary.
25 b Pression huile : mini 50 Atm, Maxi : 350 Atm). b Pression Air : 0 à 7 bars (non limitatif) 25 b Oil pressure: min 50 Atm, Max: 350 Atm). b Air pressure: 0 to 7 bars (not limited)
La presse dispose d'un boitier électrique de commande à fonctionnement automatique qui lui permet de s'arrêter lors qu'elle a atteint sa pression de travail 30 et de repartir dés que la pression décroit de 50 Atm due à l'évacuation du fluide des boues au travers les trous de la cage. Le système hydraulique est muni d'un groupe sécurité (valve automatique) en cas de défection du manomètre permettant l'arrêt immédiat de la presse. The press has an electric control box with automatic operation that allows it to stop when it has reached its working pressure 30 and start again as soon as the pressure decreases by 50 Atm due to the evacuation of the fluid sludge through the holes in the cage. The hydraulic system is equipped with a safety group (automatic valve) in case of defect of the manometer allowing the immediate stop of the press.
35 L'air étant injecté directement dans les boues, elle est constante Action du vérin par système pneumatique, Since the air is injected directly into the sludge, it is constant. Action of the cylinder by pneumatic system,
Même fonctionnement que le système hydraulique mais c'est l'air qui actionne le 40 vérin du plateau de pressage. Le dispositif ci-dessus selon l'invention peut être décliné en plusieurs dimensions, non limitatif. 455 Same operation as the hydraulic system but it is the air that actuates the 40 cylinder of the pressing plate. The device above according to the invention can be declined in several dimensions, not limiting. 455
