CATALYST SUPPLYING DEVICE IN A PRODUCING DEVICE OF CARBON NANOTUBES

摘要

PURPOSE: A catalyst supply apparatus of a device for carbon nanotube synthesis is provided, which can improve catalyst supply efficiency and accuracy by controlling the catalyst quantity supplied to a furnace. CONSTITUTION: A catalyst supply apparatus of a device for carbon nanotube synthesis comprises: a transfer device which is connected to a discharge hole of a supply tank(1) filled with catalysts and supplies the catalyst dropping in the supply tank; and a supply device which supplies the catalyst of the fixed quantity transferred by the transfer device to a furnace by the gas pressure. The transfer device includes: a transfer pipe(3) in which the dropping catalyst flows in the discharge hole of the supply tank; a screw transferring the predetermined amount catalyst; and a motor(5) which rotates the screw at the constant speed.
