Abstract

A carbon nanotube assembly manufacturing apparatus includes a synthesis furnace having a carbon nanotube synthesis space inside, and a gas supply unit that is disposed at a lower portion of the synthesis furnace and ejects an inert gas through a plurality of nozzles to converge carbon nanotubes discharged from the synthesis furnace. The plurality of nozzles are arranged along an arc of the gas supply unit so as to surround the carbon nanotubes discharged from the synthesis furnace and are individually adjustable.

Claims

1. A carbon nanotube assembly manufacturing apparatus comprising:

a synthesis furnace having a carbon nanotube synthesis space inside; and

a gas supply unit that is disposed at a lower portion of the synthesis furnace and ejects an inert gas through a plurality of nozzles to converge carbon nanotubes discharged from the synthesis furnace,

wherein the plurality of nozzles are arranged along an arc of the gas supply unit so as to surround the carbon nanotubes discharged from the synthesis furnace and are individually adjustable,

wherein the gas supply unit is spaced apart from a center of the synthesis furnace by a predetermined distance, is located so as to have a concentric relationship with the center, and is a tubular member formed in a circular shape.

2. The carbon nanotube assembly manufacturing apparatus according to claim 1, wherein the nozzle has one end fixed to the gas supply unit and the other end extended toward a center of the gas supply unit.

3. The carbon nanotube assembly manufacturing apparatus according to claim 1, wherein the nozzle is adjustable to have an acute angle toward a center of the gas supply unit in any one direction of an upper side, a lower side, a left side, and a right side.

4. The carbon nanotube assembly manufacturing apparatus according to claim 1, wherein the nozzle is disposed to be inclined in a clockwise direction or a counterclockwise direction so as to have an acute angle with respect to a plane to be coupled with the gas supply unit.

5. The carbon nanotube assembly manufacturing apparatus according to claim 1, wherein the nozzle is capable of adjusting a supply rate of the inert gas.

6. The carbon nanotube assembly manufacturing apparatus according to claim 1, further comprising:

a raw material supply unit that supplies a synthesis raw material for manufacturing the carbon nanotube assembly.

7. The carbon nanotube assembly manufacturing apparatus according to claim 1, further comprising:

a gas injection unit that is installed at one side of the gas supply unit and injects the inert gas.
