Cold firework jetting equipment

Abstract

The invention discloses cold firework jetting equipment. The equipment comprises an air supply device, a feeding device, a heating device, a cold firework nozzle, a bottom supporting board, a side supporting board, a cold firework nozzle installation board and metal powder. The equipment can overcome the multiple defects that gunpowder is needed in the set-off process of a traditional cold firework barrel, so that potential safety hazards exist, smoke and pungent smell pollution is generated in the set-off process, the jetting time is short and cannot be controlled, and a cold firework jetting device cannot be recycled; and existing cold firework jetting equipment is complex in system structure, clumsy, heavy, poor in controllability, high in cost and the like, and the cold firework jetting equipment has the beneficial effects of being safe, environment-friendly, simple in structure, long in jetting time, good in controllability, capable of being recycled and achieving the good set-off effect and the like.

Description

technical field [0001] The invention relates to the field of cold pyrotechnics, in particular to cold pyrotechnic eruption equipment. Background technique [0002] Now various stage performances mostly set off cold fireworks to heighten the atmosphere and promote the climax of performances. In terms of realizing the stage effect, it has achieved very good results. The cold pyrotechnics set off on the stage at present all use the cold pyrotechnic cylinder of disposable discharge, and the mixture of gunpowder and metal powder is packed in the cold pyrotechnic cylinder and put into ignition head device. When the cold fireworks are set off, the ignition head device is controlled by electrical connection to generate sparks to ignite the gunpowder. The high temperature generated by the combustion of gunpowder ignites the metal powder mixed with it, and the high pressure generated by the combustion of gunpowder realizes the eruption of the burning metal powder to achieve the effe...

AI Technical Summary

Problems solved by technology

This equipment overcomes the potential safety hazards of gunpowder required for discharge of traditional cold pyrotechnic tubes, smoke and irritating odor pollution during discharge, short eruption time, uncontrollable eruption time, non-recyclable cold pyrotechnic injectors, and the existing cold pyrotechnic eruption. The equipment system has many disadvantages such as complex structure, heavy equipment, poor controllability, high cost, etc. It has many advantages such as safety and environmental protection, simple structure, long eruption time, good controllability, and recyclable utilization.
