Description

La présente invention concerne les tables d'égouttage permettant l'épaississement dynamique des boues et produits pâteux. Afin de 5 séparer au maximum, solides et liquides. Dans les dispositifs connus de ce genre de matériel, les boues ou produits pâteux sont déposés par un ensemble alimentation sur une bande filtrante, qui se déplace en continu. La filtration gravitai re s'effectue tout le long de la bande. Des guides 10 latéraux maintiennent la boue ou les produits pâteux sur la bande. Des peignes peuvent en ouvrant des sillons dans la matière à traiter faciliter l'écoulement du liquide. Le liquide provenant de la séparation est recueilli dans un bac de récupération situé en partie inférieure. 15 Un ensemble de pressage peut éventuellement compléter l'égouttage gravitaire. Le produit, issu de ce traitement est séparé de la bande filtrante par un racloir en vue de son évacuation. La bande filtrante est maintenue sous tension par un dispositif spécifique, elle peut être lavée en continu lors de son retour. Tous ces éléments sont 20 solidarisés par un châssis métallique, protégés par un couvercle et placé en général à l'intérieur des bâtiments techniques. Ces tables d'égouttage permettent une réduction du volume des boues intéressante mais, faible La table d'égouttage, selon l'invention permet d'augmenter de façon 25 notable la siccité des produits traités. Elle est en effet basée sur l'utilisation d'un caisson spécifique dans lequel passe la bande filtrante. Ce caisson spécifique conjugue et permet l'utilisation de l'énergie du rayonnement solaire et de l'effet de serre pour accélérer et augmenter 30 les performance de la séparation liquides/solides. II est caractérisé par la mise en place, à l'extérieur d'un Ecran translucide qui protège de la pluie et des agressions possibles {grêlons}, recueille et conduit le condensât qui provient de l'évaporation du liquide vers la gouttière de récupération des 35 condensâts. Vient ensuite la bande filtrante traditionnelle avec le produit à traiter. The present invention relates to drip tables for dynamic thickening of sludge and pasty products. In order to separate as much as possible, solid and liquid. In the known devices of this kind of material, sludge or pasty products are deposited by a feeding assembly on a filtering band, which moves continuously. The gravitational filtration is carried out all along the strip. Side guides hold mud or pasty products on the tape. Combs can by opening grooves in the material to be treated facilitate the flow of the liquid. The liquid from the separation is collected in a recovery tank located in the lower part. A pressing assembly may optionally supplement gravity drainage. The product resulting from this treatment is separated from the filter belt by a scraper for disposal. The filter strip is kept under tension by a specific device, it can be washed continuously during its return. All these elements are secured by a metal frame, protected by a cover and placed generally inside the technical buildings. These drip tables make it possible to reduce the volume of sludge of interest, but low. The drip table according to the invention makes it possible to significantly increase the dryness of the treated products. It is indeed based on the use of a specific box in which passes the filter band. This specific chamber conjugates and allows the use of solar radiation energy and the greenhouse effect to accelerate and increase the liquid / solid separation performance. It is characterized by the setting up, outside of a translucent Screen which protects from the rain and the possible aggression {hailstones}, collects and leads the condensate which comes from the evaporation of the liquid towards the gutter of recovery of 35 condensates. Then comes the traditional filter tape with the product to be treated.

Immédiatement en dessous, le second élément du caisson spécifique, composé par un matériel réfléchissant posé sur un isolant. . Immediately below, the second element of the specific box, composed by a reflective material placed on an insulator. .

Le produit à traiter qui se trouve placé dans un caisson spécifique va bénéficier :de l'énergie du rayonnement solaire et de l'effet de serre. Dans ces conditions, l'énergie absorbée par le produit va lui permettre de s'échauffer, ce qui entraîne la vaporisation d'une partie du liquide. Ces vapeurs viennent en partie se condenser sur la face interne de l'écran translucide, Le condensât s'écoule par gravité dans la gouttière de récupération des condensats. Ces phénomènes entraînent une augmentation de la siccité des produits traités. L'évacuation des boues vers un ensemble pompe de reprise par exemple est assuré par un ensemble grattoir mobile et d'un réceptacle. Un rouleau assure la tension continue de la bande. La bande est ensuite lavée en continu par une rampe de buses alimentées en eau. Un ensemble « séchage de la bande », indépendant et situé sous le 20 caisson vient augmenter encore le rendement car, la bande étant séchée en partie va â nouveau absorber le liquide du produit â traiter_ Le châssis métallique de l'ensemble, incliné, assure la rigidité et le ent de l'ensemble des composants. De plus il intègre un bac de récupération des eaux de : lavage, condensation et des filtrats. 25 La table peut être munie d'un dispositif de vibration réglable pour faciliter la séparation liquide/solide par effet de coalescence. Un système de régulation peut asservir la vitesse de défilement de la bande à la siccité désirée en fin de procéss. L'ensemble est placé en extérieur et orienté pour bénéficier du 30 meilleur ensoleillement. Les dessins annexés illustrent l'invention. La figure 1 est une vue en perspective illustrant le principe du caisson avec ses deux éléments : la partie supérieure (1) translucide, la partie inférieure (2) composée d'un ensemble réflecteur/isolant ces deux 35 éléments réalisent la « serre » dans laquelle la bande transporteuse du produit(4) va circuler, le produit va s'échauffer, se libérer d'une partie de son liquide par échauffement, évaporation/condensation et égouttage. The product to be treated placed in a specific box will benefit from the energy of solar radiation and the greenhouse effect. Under these conditions, the energy absorbed by the product will allow it to heat up, resulting in the vaporization of a portion of the liquid. These vapors partially condense on the inside of the translucent screen. The condensate flows by gravity into the condensate recovery channel. These phenomena lead to an increase in the dryness of the treated products. The evacuation of sludge to a recovery pump assembly for example is provided by a mobile scraper assembly and a receptacle. A roller ensures the continuous tension of the web. The strip is then washed continuously by a nozzle ramp supplied with water. A separate "belt drying" assembly located below the box further increases the efficiency because the strip being partially dried will again absorb the liquid from the product to be treated. The metal frame of the assembly, inclined, ensures rigidity and ent of all components. In addition it integrates a water collection tank: washing, condensation and filtrates. The table may be provided with an adjustable vibration device to facilitate liquid / solid separation by coalescing effect. A control system can enslave the tape speed to the desired dryness at the end of the process. The set is placed outside and oriented to benefit from the best sunshine. The accompanying drawings illustrate the invention. FIG. 1 is a perspective view illustrating the principle of the box with its two elements: the translucent upper part (1), the lower part (2) consisting of a reflective / insulating assembly, these two elements produce the "greenhouse" in which the conveyor belt of the product (4) will circulate, the product will heat up, release some of its liquid by heating, evaporation / condensation and draining.

Tel qu'il est représenté, le dispositif comporte le premier élément du caisson spécifique à savoir un écran translucide (1) qui permet la captation de l'énergie du rayonnement solaire et participe â l'effet de serre (de plus, il protège de la pluie, des agressions extérieures, grêlons. Le second élément du caisson spécifique, le réflecteur (2) est constitué par un matériel réfléchissant posé sur un isolant. Le but de ce second élément est de réfléchir une partie de l'énergie solaire vers le dessous de la bande. L'isolant permet de limiter les pertes thermiques et d'augmenter de ce fait la température dans le caisson spécifique. De plus il recueille une partie du liquide(évaporation/condensation) provenant du produit traité, Comme sur une table d'égouttage K classique »on trouve : Un dispositif d'alimentation des boues (3)qui sont déposées sur la bande filtrante (4) - Un ensemble grattoir mobile (5) qui permet le détachement de la boue épaissie du tapis et l'envoie vers une évacuation (6). Un rouleau de tension (?) assure une bonne tenue à la bande. - Les eaux d'écoulement provenant de la condensation sous l'écran translucide sont recueillies par la gouttière de récupération (8). Un bac de récupération(9)recueille les eaux provenant de l'égouttage sur le réflecteur(2),du lavage de la bande ,ainsi que celles de la gouttière de récupération (8) - Une section de lavage en continu (12), de la bande est assurée par des buses alimentées en eau Un système de régulation(11) qui peut venir asservir l'entraînement et la vitesse de défilement de la bande au taux de siccité désirée en fin de process - Un châssis (IO) qui assure la liaison des différents composants constituant la table d'égouttage.
