Abstract:
1. An apparatus for separating resin and metal to separate a resin material composing an insulating material and a metallic material so as to separate and to retrieve the insulating material composing a printed circuit board and the metallic material including a printed metallic material and also composing the printed circuit board from a waste printed circuit board, which is used in waste electric equipment or a waste produced in a process of manufacturing electric equipment, comprising; a pressurizing means for pressurizing the waste printed circuit board, a heating means for heating up the waste printed circuit board to a predetermined temperature at which the waste printed circuit board is at least softened, and a filtering means for filtering the resin material from the waste printed circuit board that is maintained at the predetermined temperature by means of the heating means, wherein: the insulating material is made of either thermoplastic resin only or a mixture of thermoplastic resin and an inorganic loading material, the filtering means filters the insulating material only, the filtering means is made of a sintered metal, and the filtering means includes a filter, which passes only the resin material from the waste printed circuit board, the pressurizing means includes a driving shaft, which has a rotational body for transporting the waste printed circuit board, a driving unit, which rotates the driving shaft, and a holder unit, which accommodates the rotational body, a predetermined pressure caused by a rotational force of the rotational body is applied to an inner circumference wall of the holder unit, the driving shaft of the rotational body is disposed in a vertical direction, the filtering means is disposed and exposed on the inner circumference wall of the holder unit, so that the resin material is retrieved in the radial outward direction of a driving shaft, and the rotational body rotates within the inner circumferential wall of the holder unit, which is provided by a circumferential wall of the filtering means.
