Problems solved by technology

[0002] Fireworks are launched into the air at present using black powder, which produces a large amount of harmful gas and smoke particles when the black powder burns, and also produces a lot of residues when the packaging and fuses of the black powder burn, all of which cause serious pollution to the environment. Fireworks are banned and restricted in many places in the country and even in the world, which has greatly hindered the development of the fireworks economy

Embodiment 1

[0023] Example 1, such as figure 1 As shown, a firework lift-off device has a steel container with a closed bottom and an open upper end. The lower part of the container is a combustion chamber 4, and the upper part of the container is a guide channel 1. There is a fireworks support between the combustion chamber 4 and the guide channel 1. Flange 3, spherical fireworks (can also be replaced by cylinder fireworks) 2 are placed on the fireworks support flange 3, an arc igniter 5, a combustion-supporting gas input port 9 and a combustible gas input port 6 are provided on the side wall of the combustion chamber 4 to support combustion The gas input port 9 is connected to the combustion-supporting gas solenoid valve 8 through a pipeline, the combustion-supporting gas solenoid valve 8 is connected to the combustion-supporting gas cylinder (not shown in the figure) through a pipeline, and the combustible gas input port 6 is connected to the combustible gas solenoid valve 7 through a ...

Embodiment 2

[0034] Example 2, such as figure 2 As shown, except that there is only one mixed gas input port 10, others are the same as in Embodiment 1. The mixed gas input port 10 is connected with the combustion-supporting gas solenoid valve 8 and the combustible gas solenoid valve 7 through the pipeline, the combustion-supporting gas solenoid valve 8 is connected with the combustion-supporting gas cylinder (not shown in the figure) through the pipeline, and the combustible gas solenoid valve 7 is connected with the combustible gas solenoid valve through the pipeline. Combustible gas cylinders (not shown in the figure) are connected.

Abstract

The invention discloses a firework lift-off device and an operation method thereof. The firework lift-off device is provided with a container with a closed bottom end and an open upper end, a combustion chamber is arranged at the lower portion of the container, a guide channel is arranged at the upper portion of the container, a firework supporting flange is arranged between the combustion chamber and the guide channel, and at least one igniter and at least one gas input port are arranged on the side wall of the combustion chamber. The gas input port is connected with a combustion-supporting gas electromagnetic valve and/or a combustible gas electromagnetic valve, the combustion-supporting gas input port of the firework lift-off device is connected with the combustion-supporting gas electromagnetic valve, the combustible gas input port is connected with the combustible gas electromagnetic valve, and the combustion-supporting gas electromagnetic valve, the combustible gas electromagnetic valve and the igniter are electrically connected with a controller. The operation method comprises the steps that fireworks are placed on the firework supporting flange, then the opening time of the electromagnetic valves is controlled, the combustion chamber is inflated, and finally the controller controls the igniter to ignite. The method has the advantages that a large amount of harmful gas and smoke dust particles are eliminated, the environment is protected, and development of the firework industry is promoted.

Description

technical field [0001] The invention relates to the technical field of fireworks, in particular to a fireworks lift-off device and an operating method thereof. Background technique [0002] Fireworks are launched into the air at present using black powder, which produces a large amount of harmful gas and smoke particles when the black powder burns, and also produces a lot of residues when the packaging and fuses of the black powder burn, all of which cause serious pollution to the environment. The prohibition and restriction of fireworks in many parts of the country and even in the world has greatly hindered the development of the fireworks economy. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a firework lift-off device with a simple structure and an operation method thereof. [0004] The present invention adopts the following technical solutions. [0005] A firework lift-off device, comprising a contai...
