The invention relates to an
intelligent control device for
drying bright beads of
fireworks and firecrackers. The
intelligent control device comprises a human-
machine interface
operating system, a PLC (
programmable logic controller) and a frequency converter
control system, a
drying air heater and an air supply
system thereof, and a temperature-
humidity sensor
control system. The
intelligent control device has the advantages that the technical level in the intelligent monitoring for the temperature and the
humidity of a
drying chamber for drying the bright beads is improved, the human-
machine separation is realized, major production safety accidents about drying the bright beads in the production process of the
fireworks and the firecrackers are effectively prevented and avoided, and the occupational
hazard of firework agents to operators is prevented; simultaneously, due to the PLC and the frequency converter
control system, the production process for drying the bright beads in the production process of the
fireworks and the firecrackers is optimized; due to a frequency converter is adopted to drive the drying
air heater, the speed adjusting performance is excellent, the power-saving effect is obvious, closed-
loop control for the temperature and the
humidity of the drying chamber is realized, the
operating frequency of the hot
air heater is accurately adjusted, the quality of products is improved, the production cost is reduced, the
automation and the intelligentization in production of the bright beads of the fireworks and the firecrackers are realized, and the supporting platform of new technologies and safety technologies is improved.
