DEVICE FOR DRYING SAPROPEL Russian patent published in 2007 - IPC F26B15/24 

FIELD: drying engineering.

SUBSTANCE: device comprises pressure-tight casing, endless two-chain flexible member that is turned over the sprockets mounted on the semi-axles and made of vertically oriented loop sections and closing horizontal branch mounted on the load-bearing rollers above the loop sections, heat exchanger, charging device, and discharging device. The chains are interconnected through the transverse links arranged along the length of the member at the same distance one from the other. The rectangular grates are freely suspended to the lateral links and overlaps the intervals between the adjacent lateral links. The air passages made of deflecting walls are defined inside the pressure-tight casing in the direction of the member. The heat exchanger is made for permitting heated air to flow over all loop sections. The shield made of a heat-resistant cloth is mounted in the central zone of each loop section.

EFFECT: enhanced reliability.
