CONTINUOUS WASHING DEVICE WITH RISING SCREW

摘要

PURPOSE: A continuous washing apparatus using a rising screw is provided to improve the quality of a recycling product and to remove the foreign material or the dirt of the surfaces of PET flakes because PET flakes are inserted in a washing liquid for a predetermined time by moving PET flakes with a rising screw which is vertically installed in a washing tub. CONSTITUTION: In a continuous washing apparatus using a rising screw, a screw pipe(12) in which a rising screw(2) is formed in the inside center of a washing tub(1) in which a PET flake is put. A screw pipe(12a) in which a rising screw(2a) is formed in the inside center of a settling tank(11) which is connected to the upper end of the screw pipe through a raw material transfer path(8). A partition(4,4a) is installed in the lower end of each screw pipe to cut off the vortex flow of a washing liquid. PET flakes falling to the lower part of the settling tank and the washing tub after passing through the washing liquid are successively piled up, and is moved by the rising screw.
