Carbon nanotube cracking device

The utility model discloses a carbon nano tube cracking device which comprises a mixing box, a cracking box and a discharging box, and a cracking assembly comprises a feeding pipe, a micro sucking pump, a communicating pipe, a rotating motor, a rotating shaft, a propeller blade, an electric heating plate, an electric push rod, a track and a material receiving box. The utility model belongs to the technical field of carbon nano tube cracking, and particularly relates to a carbon nano tube cracking device which is characterized in that inert gas, cocatalyst gas, reducing gas, a catalyst and a carbon source are added through different feeding pipes and then are more fully mixed, so that the gas continuously rotates and is fully cracked in cooperation with heating of an electric heating plate, and then the gas is cracked to generate carbon nano tubes; and the carbon nanotubes are uniformly collected by the material receiving box and are mechanically collected and taken out by the electric push rod. 本实用新型公开的一种碳纳米管
