The present invention relates to a wet sorting apparatus for sorting waste plastic by using specific gravity difference. The wet sorting apparatus includes: a pulverizer; a processing bath including a body with a hollow structure in which a top surface is open, and a hopper attached to one upper end portion of the body and disposed at a lower end portion of a transfer conveyer; a transfer blade; a horizontal separating plate; a first sorting device positioned on the horizontal separating plate, configured as a screw to rotate across a length direction of the processing bath, and having rotating blades symmetrically formed around a center to collect waste plastic particles having high specific gravity in the center; a second sorting device rotatable across the length direction of the processing bath in adjacent to a bottom surface of the body of the processing bath; a first convey screw having one end provided at the other upper end of the processing bath to which the hopper is attached and conveying waste plastic particles having low specific gravity transferred by the transfer blade; a second convey screw including a convey tube having one end communicated with one side of the processing bath, which is a position adjacent to an upper surface of the horizontal separating plate, and a screw installed in the convey tube; and a third convey screw having one end positioned at a lower surface of the horizontal separating plate and being adjacent to an inner bottom surface of the processing bath. Since the sludge and the waste plastic particles having high specific gravity can be easily sorted, the resource reutilization can be improved and a serious problem about the secondary contamination of the natural environment can be solved. |
