Abstract

The invention discloses cold fireworks spraying equipment. The equipment comprises a feeding device, a cold fireworks nozzle, a heating device and an air supply device; the cold fireworks nozzle comprises a ventilation pipe (26) and a feeding pipe (27) for communicating with each other; the feeding device is used for conveying metal powder to the intersection of the ventilation pipe (26) and the feeding pipe (27); the heating device sleeves the feeding pipe (27); and the air supply device is used for conveying wind to the ventilation pipe (26) so as to ignite and spray the heated metal powder. Compared with the prior art, the equipment is simple and portable in structure under the preconditions of satisfying safety and environmental protection, and preferably facilitates setting-off of cold fireworks.

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...
