Metal film and resin separation method and separation apparatus thereof

A metal film and resin separation apparatus that puts synthetic resin waste in which a metal film adheres to a synthetic resin into a separation chamber in a casing, crushes the synthetic resin waste in the separation chamber, and separates and recovers the metal film and synthetic resin, the metal film and resin separation apparatus comprising:

• a heater attached to the casing, the heater that heats the separation chamber in temperature;
• a water sprinkler that sprinkles water into the separation chamber;
• a hammer rotor in which a disc is fixed to a rotation shaft axially supported to be driven to rotate in the separation chamber in a transverse direction to the axis, and a plurality of hammers are pivotably supported on the disc;
• a discharge port provided in a side wall portion of the casing, the discharge port through which a crushed synthetic resin waste is discharged from the separation chamber;
• a resin recovery chamber provided on the outside of the discharge port;
• a metal recovery box provided in the resin recovery chamber to be capable of being elevated and lowered, the metal recovery box in which a metal film exfoliated from the synthetic resin is recovered from an interior of the separation chamber through a perforated plate;
• an elevating and lowering device that elevates the metal recovery box from the resin recovery chamber to an exterior of the chamber;
• a discharge conveyor provided in a bottom portion of the resin recovery chamber, the discharge conveyor that discharges a synthetic resin after exfoliation from which the metal film is already exfoliated;
• and
• a temperature controller that, by controlling the heater and also controlling a water sprinkling amount of the water sprinkler, controls the temperature in the separation chamber to an exfoliation temperature which is higher than a normal temperature and less than a melting temperature of the synthetic resin, the exfoliation temperature at which the synthetic resin and the metal film are exfoliated.

• a heater attached to the casing, the heater that heats an interior of the separation chamber;
• a water sprinkler provided in the separation chamber, the water sprinkler that sprinkles water into the separation chamber;
• a hammer rotor disposed to be driven to rotate in the separation chamber in the casing, the hammer rotor in which a plurality of hammers are pivotably supported on a disc fixed in a transverse direction on a rotation shaft;
• a resin discharge port provided in a side wall portion of the casing, the resin discharge port through which a crushed synthetic resin is discharged from the separation chamber;
• a resin discharge door openably and closably provided in the resin discharge port;
• a metal discharge port provided in the other side wall portion of the casing, the metal discharge port through which a crushed metal film is discharged from the separation chamber;
• a screen provided in the metal discharge port, the screen through which the metal film passes while leaving the synthetic resin in the separation chamber;
• a suction device connected to the metal discharge port, the suction device that suctions and takes out air and a metal film in the separation chamber to an exterior through the screen;
• and
• a temperature controller that, by controlling the heater and also controlling a water sprinkling amount of the water sprinkler, controls a temperature in the separation chamber to an exfoliation temperature which is higher than a normal temperature and less than a melting temperature of the synthetic resin, the exfoliation temperature at which the synthetic resin and the metal film are exfoliated.
