SOLID-LIQUID SEPARATION METHOD AND SOLID-LIQUID SEPARATION DEVICE FOR PARTICLE AGGREGATE DISPERSION LIQUID

摘要

PROBLEM TO BE SOLVED: To collect particle aggregates from a particle aggregate dispersion liquid as high-concentration cake without impairing quality at low cost in a short time.;SOLUTION: This solid-liquid separation device 40 for the particle aggregate dispersion liquid performing solid-liquid separation of the particle aggregate dispersion liquid wherein the aggregates of particles are dispersed in a solvent includes: a traveling long filter material 42; a coating device 46 imparting the particle aggregate dispersion liquid onto the surface of the filter material 42 in a thin layer state to form a dispersion liquid layer; a liquid absorption material 47 absorbing the solvent in the dispersion liquid layer through the filter material 42 to form a concentrated cake layer of the dispersion liquid on the filter material 42 surface; a transfer roller 48 having the roller surface formed of a material having wettability to the concentrated cake layer larger than the filter material, and transferring the concentrated cake layer onto the roller surface from the filter material 42 surface by pinching the concentrated cake layer on the filter material 42 with a backup roller 56C; and a scraper 50 peeling and collecting the concentrated cake transferred onto the transfer roller 48 from the roller surface.;COPYRIGHT: (C)2012,JPO&INPIT
