Example Embodiment

[0028] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0029] like figure 1 As shown, the overall structure of the equipment includes: air supply device 1, feeding device 2, heating device 3, cold flame nozzle 4, bottom support plate 5, side support plate 6, cold flame nozzle mounting plate 7 and metal powder 8.

[0030] like figure 2 As shown, the air supply device 1 includes a bellows 9, an impeller 10 and a drive motor 11. The impeller 10 is mounted on the shaft of the drive motor 11. The drive motor 11 is installed between the bellows 9 and the side support plate 6 through bolts. The bellows 9 is welded by welding. , which is vertically fixed on the bottom support plate 5. The impeller 10 is driven by the driving motor 11 to provide a stable and suitable air flow source for the cold firework ejection device. The bellows 9 plays the role of storing and buffering the airflow. The air flow generated by t...

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...
