MIXER-SETTLER Russian patent published in 1996 - IPC

FIELD: chemical industry processing apparatuses. SUBSTANCE: mixer has inner and outer pipes. Outer pipe lower part using pipes communicates through reverse valves with following stages and its upper part - with pulp pipeline. one end of inner pipe is mounted so as to have clearance between it and feeding pipelines coupling hole and another end using branch-pipe is protruded through outer pipe wall outside. Inner pipe protruded end has reverse valve and in ring-type clearance between pipes additional fitting on for preliminary dispersion of solutions is mounted. Mixer in a stage is mounted along central axis. EFFECT: decreased power consumption during solutions dispersion process and simplified design.
