COLD FIREWORK ERUPTION APPARATUS AND COLD FIREWORK ERUPTION METHOD

摘要

Disclosed is a cold firework eruption apparatus, comprising: a material discharge mechanism (1) used for storing metal powder (6) and discharging material in a rotary pushing manner; a feeding pipe (2) connected to an output end of the material discharge mechanism (1) and used for conveying the metal powder (6) and activating and igniting the metal powder (6) during the conveying process; an outlet pipe (3) connected to an output end of the feeding pipe (2) and used for making the ignited metal powder (6) erupt; and an air-feeding mechanism (4) used for supplying an airflow into the outlet pipe (3) so as to make the ignited metal powder (6) erupt to the outside. The air-feeding mechanism (4) is connected to an air-feeding branch pipeline (401) extending to the feeding pipe (2) and used for feeding air from an input end for the metal powder (6) of the feeding pipe (2) to an output end for the metal powder (6) of the feeding pipe (2) so as to drive the metal powder (6) in the feeding pipe (2) to flow towards the outlet pipe (3). The feeding pipe (2) is externally provided with an ignition and heating device (5) for activating and igniting the metal powder (6) in an inner cavity of the feeding pipe (2) by means of heating the outer surface of the feeding pipe (2) with a flame. The eruption speed of the metal powder (6), the combustion effect of the metal powder (6), etc. are controlled so as to achieve a better eruption effect.
