SAPROPEL DEWATERING MACHINE Russian patent published in 2008 - IPC C05F7/00 C02F11/12 

FIELD: agriculture.

SUBSTANCE: machine incorporates a sapropel pressure-feed device, an unloading device, a process device to withdraw water from the sapropel mass made up of a flexible belt traveling in the vertical plane over the drive and tension drums and furnished with beads on its edges for the said sapropel mass to be laid thereon. The aforesaid machine includes also water separators, each representing a continuous flexible belt traveling over the said two drums with its outer surface furnished with a loose capillary-structure material layer. The bearing housings fitted in the shafts of one of the drums are arranged so as to be moved and locked in the guides. The machine comprises, as well, a hollow perforated squeezer roll arranged on the end of pivoted lever to revolve and interact with the water separator flexible belt suck-out layer. An inclined water withdrawal chute is arranged under the squeezer roll, while the flexible belt upper run in the water separator drum area is arranged to be sagged and to embrace the said drum from below. The water separator belt edges are inclined towards the feed device, one of them embracing the drive drum and linked with it via a gear set that features a gear ratio equal to unity. The lower drums are arranged on the machine frame, the squeeze roll lever pivots being fixed on the upper edges of the bearing housings. Note that elongation factor of the said belts is taken to exceed the linear expansion factor of the loose capillary porous water-saturated layer. The complete set of the equipment is arranged in a heat-insulated casing allowing feeding air heated to 50 to 70 C° thereto.

EFFECT: higher efficiency of sapropel dewatering, lower labour, material and power inputs.
