METHOD AND DEVICE FOR PASSING EXTRACTION SOLUTIONS TO WIDE SETTLER Russian patent published in 2002 - IPC

FIELD: liquid extraction technique. SUBSTANCE: proposed method consists in passing solutions mixed in mixing space for forming dispersion to wide settler and smoothly distributing the dispersed flow over entire width in such way that dispersed flow from last mixer of mixing reservoir passes to settler through vertical channel. Dispersed flow is fed to settler from below; it is fed to center part of supply end wherefrom dispersed flow is distributed in channel- shaped closed space inside settler over its entire before discharge directly to settler. Dispersed flow is passed through vertical channel in device for passing the solution from last mixer to wide settler and for smooth distribution of dispersion over entire width. Vertical channel is communicated with interior of settler by means of closed distributing dispersion channel found in front portion of settler which run to its side walls. EFFECT: enhanced distribution of dispersed flow over entire width of settler. 31 cl, 8 dwg, 1 tbl
