<p>PROBLEM TO BE SOLVED: To provide a waste plastic continuous treating apparatus which prevents attachment of a melt plastic to a decomposition tank and also recovers oil components by continuously separating the oil components from residues. SOLUTION: The apparatus has a decomposition tank 1 wherein a melted plastic is introduced and the oil component of the melted plastic is separated by heating from the peripheral part, a stirring means 2 which stirs the melted plastic in the decomposition tank 1 and a residue discharge means 3 which is located at the bottom part of the decomposition tank 1 and discharge the residues wherein the oil components are removed from the melted plastic. The stirring means 2 has agitating blades 21 and 22 for promoting leveling of temperature distribution and properties of the melted plastic in the decomposition tank and a driving means for rotating the agitating blades, and the residue discharge means 3 has a residue discharge screw 36 for discharging the residue residing at the bottom part of the decomposition tank, a screw casing 32 which lodges the residue discharge screw, a driving means for rotating the residue discharge screw, etc.</p> |
