Abstract

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.

Description

technical field

[0001] The invention belongs to the field of drying control devices, and relates to an intelligent control device for drying bright beads of fireworks and firecrackers, which is suitable for drying pyrotechnic agents in the production process of fireworks and firecrackers. Background technique

[0002] Fireworks and firecrackers are recreational civil explosives involving safety and environmental protection. The pyrotechnic agent used in fireworks and firecrackers to produce various fireworks effects is a multiphase solid mixture made of a variety of chemicals. Therefore, the requirements for the drying process of bright beads in the production of fireworks and firecrackers are very strict, and the drying temperature, humidity and temperature rise rate should be precisely controlled, otherwise it will cause major safety production accidents and occupational hazards. However, at present, the drying process of bright pearls in the production process of firewor...
