POLYSTYRENE SOLUTION SEPARATION AND RECOVERY APPARATUS

摘要

PROBLEM TO BE SOLVED: To efficiently allow a solvent to be vaporized from a polystyrene solution and enable polystyrene to be stably taken out in the form of thread. SOLUTION: In a polystyrene solution separation and recovery apparatus where a polystyrene solution obtained by resolving expanded polystyrene in a solvent is heated while carrying it forward through a cylinder 2 to vaporize the solvent and separate it from polystyrene and then the solvent is recovered, a stirring axis 4 equipped with axially adjacent mixing blades 3 circumferentially displaced is installed within the cylinder 2.
