Abstract

La présente invention concerne un dispositif de déshydratation de structure simple qui peut ainsi être rendue compacte, qui est facile à entretenir et à réparer, et qui est capable d'éliminer efficacement l'humidité contenue dans les boues. Selon un mode de réalisation de la présente invention, un dispositif de déshydratation comprend : un châssis de base ; une cuve de déshydratation installée sur la partie supérieure du châssis de base, la cuve de déshydratation comportant un tube à vide prévu sur un côté de sa partie supérieure et un tube d'aspiration des boues prévu sur son autre côté ; des première et seconde trappes couplées de façon rotative d'un côté et de l'autre de la cuve de déshydratation respectivement ; une plaque filtrante de compression ayant une surface arrière couplée à une extrémité d'un cylindre de compression installé sur la première trappe de façon à comprimer les boues aspirées dans la cuve de déshydratation à travers le tube d'aspiration de boue ; une plaque filtrante de support installée sur la seconde trappe de façon à faire face à la plaque filtrante de compression et à supporter la boue comprimée par la plaque filtrante de compression ; et une section antifuite installée sur la surface arrière d'au moins une parmi la plaque filtrante de compression et la plaque filtrante de support de telle sorte que, lorsqu'une boue est comprimée entre la plaque filtrante de compression et la plaque filtrante de support, la boue ne puisse pas s'échapper par le côté arrière de la plaque filtrante de compression ou de la plaque filtrante de support. Une soupape est disposée dans une position prédéterminée sur la partie inférieure de la surface extérieure de chacune des première et seconde trappes de telle sorte que l'humidité séparée de la boue comprimée entre la plaque filtrante de compression et la plaque filtrante de support peut être évacuée.
