Title
(EN) DEVICE AND METHOD FOR CLEANING MONOCRYSTALLINE PULLING APPARATUS
Abstract
(EN)

A device for cleaning the inside of a monocrystalline pulling apparatus includes a main tube unit to be inserted into a pull chamber and an inner surface cleaning mechanism that is provided at an upper part of the main tube unit and cleans the inner surface of the pull chamber. The main tube unit includes a retreat/housing section into which a seed chuck provided at the lower end of a wire retreats and which houses the seed chuck therein, and a continuous extension mechanism that is provided at the lower part of the main tube unit and to which a plurality of extension rods are capable of being added and joined. Accordingly, the inner surface of the pull chamber is efficiently cleaned.
