LIFTING DEVICE OF TOP VESSEL FOR POLYCRYSTLINE SILICON INGOT PRODUCING APPARATUS

摘要

PURPOSE: A lifting apparatus of a top bezel for a poly-crystalline silicon ingot manufacturing device is provided to prevent a chamber from being exploded by automatically opening a top vessel from a middle vessel. CONSTITUTION: A driving part(110) is pivotally installed in a middle vessel in a vertical direction. A lifting member(120) is lifted and dropped with the drive of the driving part. A bracket(130) connects the interval between a top vessel and the lifting member. The bracket is separably mounted on a top end portion of the lifting member to be spaced from an upper portion of the middle vessel with pressure if the pressure rises inside the chamber.
