摘要

PROBLEM TO BE SOLVED: To efficiently pull out inner cylinders of a large quantity of used NaS batteries. SOLUTION: A large number of NaS batteries W are arranged inside a work setting vessel 1 by turning port parts downward. This work setting vessel 1 is soaked in an Na melting zone 4 of a heated oil tank 3, and Na inside the NaS batteries is melted. Next, the work setting vessel 1 is transferred to an inner cylinder pulling-out zone 5, and inner cylinders of the NaS batteries W are simultaneously pulled out in large numbers from both sides through a hole 2 of the work setting vessel 1 by plural pulling-out heads 9 and 9 arranged on both sides.
