摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide an oil-making apparatus from plastics capable of achieving the shortening of decomposition time and energy conservation by grasping the state of the inside of a decomposition furnace without depending on vision, monitoring decomposition process and judging the termination of decomposition. SOLUTION: The oil-making apparatus from plastics comprises a decomposition furnace 1 for decomposing charged plastics by heat and a vibration sensor 14 for detecting the vibration generated from the decomposition furnace 1. A judging unit performs the monitoring or the termination judgment of thermal decomposition of the plastics in the decomposition furnace 1 based on the vibration detected by the vibration sensor 14.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus used for continuously converting waste plastics into an oil and being capable of measuring the weight, flow rate, inventory, level, etc., of the melt by providing valves, a branching pipe and a melt sampling chamber with the main pipe of an apparatus consisting of an extruder for kneading mixed waste plastics containing vinyl chloride polymers. SOLUTION: This invention provides an apparatus for continuously thermally converting waste plastics containing vinyl chloride polymers into an oil, wherein a branching pipe 24 is provided in the main pipe 4a at the inlet of a heat decomposition furnace 5, the pipe 24 is connected through a valve 26 to a chamber 25 for collecting a melt of waste plastics, a valve 28 is provided in the main pipe in position downstream of the branching point of the branching pipe. During an ordinary operation, the valve 26 is kept shut. When the flow rate of the melt is measured, the valve 28 is shut to sample the melt in a container 30, and the melt is weighed with a weight meter 29. The residue is taken out in a container 17 within a residue discharge chamber 16 and weighed with a weighing meter 32. The flow rate, inventory, etc., of the melt are estimated from these measurements.
