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

[0024] Example 1, such as Figure 1-2 As shown, a fireworks lift-off device array includes a fireworks lift-off device A 10, a fireworks lift-off device B 13, a fireworks lift-off device C 17 and a fireworks lift-off device D 21, and they are arranged and fixed on a trolley 12. . Take the structure of fireworks lift-off device A 10 as an example, it is a steel container with a closed bottom and an open upper end, the lower part of the container is a combustion chamber 4, the upper part of the container is a guide passage 1, and there is a gap between the combustion chamber 4 and the guide passage 1. A firework supporting flange 3, spherical fireworks (can also be replaced by cylindrical fireworks) 2 are placed on the fireworks supporting flange 3, an arc igniter 5, a combustion-supporting gas input port E9 and a combustible gas input port are provided on the side wall of the combustion chamber 4 A6, the combustion-supporting gas input port E9 is connected to the combustion-s...

Embodiment 2

[0034] Example 2, such as image 3 As shown, the difference from Embodiment 1 is that the combustible gas input port of each fireworks lift-off device in the fireworks lift-off device array is connected to a combustible gas solenoid valve separately through a pipeline, and the combustible gas solenoid valve is connected to a combustible gas cylinder through a pipeline. (not shown in the figure) connected. The combustion-supporting gas input port of each fireworks lift-off device is separately connected with a combustion-supporting gas electromagnetic valve through a pipeline, and the combustion-supporting gas solenoid valve is connected with a combustion-supporting gas cylinder (not shown in the figure) through a pipeline. The combustible gas input port A6 of the fireworks lift-off device A 10 is independently connected with a combustible gas solenoid valve I7 through a pipeline, and the combustion-supporting gas input port E9 of the fireworks lift-off device A 10 is connected...

Abstract

The invention discloses a firework lift-off device array and an operation method thereof. Two or more than two firework lift-off devices are arranged together, each 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 each container, a guide channel is arranged at the upper portion of each container, and a firework supporting flange is arranged between each combustion chamber and the corresponding guide channel. The side wall of each combustion chamber is provided with at least one igniter, at least one combustion-supporting gas input port and at least one combustible gas input port, the combustion-supporting gas input port of each firework lift-off device is connected with a combustion-supporting gas electromagnetic valve, and the combustible gas input ports are connected with combustible gas electromagnetic valves. The operation method comprises the steps that fireworks are placed in all the firework lift-off devices, then the opening time of all the electromagnetic valves is controlled, the combustion chambers are inflated, and finally the igniters of all the corresponding firework lift-off devices are controlled 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 an array of fireworks lifting devices and an operation 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 present invention provides an array of fireworks lifting devices with a simple structure and an operation method thereof. [0004] The present invention adopts the following technical solutions. [0005] An array of firewo...
