EXTRACTOR FOR THE SYSTEM LIQUID-LIQUID Russian patent published in 1995 - IPC

FIELD: chemical engineering. SUBSTANCE: extractor casing is made in the form of a column along whose axle a rotor-shaft is mounted. The casing is divided in height into sections by the partitions having the shape of a hopper. Basins with a perforated lateral surface are mounted on the shaft in the upper sections. The perforation size increases according to the basin height. The bottom and the inner lateral surface of the basins as well as the inner surface of the sections in which the basins are located, are equipped with a three-dimensional cellular grid. The grid is fixed to the extractor casing by means of flexible members. Mixing devices in the shape of upset frustums are mounted on the shaft in the lower sections. EFFECT: intensified extraction process and reduced power consumption. 2 cl, 2 dwg
