CONTINUOUS COAGULATION DEVICE AND MULTI-STAGE POLYMERIZATION DEVICE PROVIDED WITH THIS

摘要

PROBLEM TO BE SOLVED: To provide a continuous coagulation device for enhancing an efficiency when a water-absorptive resin is prepared by a multi-stage polymerization; and a multi-stage polymerization device provided with this. SOLUTION: The continuous coagulation device 100 includes a first end wall; a second end wall opposed to it; and a peripheral wall approximately horizontally extending therebetween and is constituted by a coagulation tank 20 defining an approximately horizontal flow passage; feed ports 11, 12 for continuously feeding a fluid material to the coagulation tank 20 and provided at the first end wall side; a discharge port 13 for continuously discharging the fluid material from the coagulation tank 20 and provided at the second end wall side; a rotation shaft part 31 approximately horizontally extending at the inside of the coagulation tank 20; and a stirring blade 32 mounted to the rotation shaft part.
