FIELD: process engineering, transportation.

SUBSTANCE: invention relates to dehydrate loose materials and doubles for unloading them. It is intended for coal, mining and other industries. The proposed device comprises a housing, bottom with gate furnished with water offtake chute and spring-loaded driven actuator mounted vertically along the housing axis. The housing inner and outer walls consist of three rows of vertical rods, crosswise beams, ties and filtration screen fastened, wave-shapely, on rods of outer and central rows. Inner row rods are arranged with a spacing making at least half the maximum size of loose material slump, while central row rods are arranged on appropriate diametric line of inner row rods with the gap between them making the size required for mounting inner-row ties and filtration screen attachment. Inner-row rods are mounted in gaps between central-row rods and serve for wave-shaped attachment of filtration screen.
