Abstract
The invention discloses a carbon nano tube dispersion device belonging to the field of dispersion of nano materials. The device is mainly composed of a carbon nano tube spraying device, an airflow channel and a collection device. A liquefied gas working medium in the carbon nano tube spraying device enters the inner part of a carbon nano tube; in an application process, a nozzle switch is switched on so that the clustered carbon nano tube can be sufficiently dispersed by using the phase change of the working medium; a heating belt and a stirring paddle are used for realizing the aims of heating and sufficiently mixing, and the dispersion of the carbon nano tube is complete in the process and the pollution to the carbon nano tube is not caused; the dispersed carbon nano tube is driven by the flowing of the gas working medium to move to a bottom collection device of the device in the airflow channel; and the collection device is driven by a magnetic stirring device so that the carbon nano tube is uniformly dispersed in a collection process. The dispersion effect on the carbon nano tube is good and the efficiency is high, the device is simple and convenient to control and the use and maintenance costs are low.
