Abstract

PURPOSE:To improve expression power and impression degree and to safely inject a colored flame which can call a topic by injecting mixed colored fluid of combustible liquid and flame coloring material from an atomizing nozzle port and igniting the injected, atomized mixed colored fluid. CONSTITUTION:Combustible liquid (e.g. alcohol or the like) supplied from a combustible liquid supply system 2 and flame coloring material (e.g. sodium ion solution, iron ion solution, cobalt ion solution, etc.) supplied from a flame coloring material supply system 3 are combined at combining points P1, P2, P3. Immediately after the mixed fluid of the combustible liquid and the coloring material is injected from the outlet of an atomizing nozzle 4 via an extrafine rodlike element, it becomes an atomized flow at an air-fuel ratio of a burning range. The atomized flow of the mixed fluid is ignited by an igniter 5 thereby to generate a flame flow colored by the flame reaction of the coloring material. The mixed fluid is continuously supplied thereby to inject the colored flame from the nozzle 4.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame ejection device suitable for installation in, for example, an event site.

[0002]

2. Description of the Related Art Conventionally, a fountain device for ejecting transparent water from a fountain nozzle is well known. However, since the fountain obtained by this type of fountain device merely ejects a transparent water rod, it has relatively low expressive power and low impression. Therefore, it has a drawback of lacking topicality. Therefore, by developing a flame ejection device that ejects colored flames in consideration of safety, it improves the impression level and arouses topicality compared to conventional fountain devices that simply eject transparent water. It is thought that it will be possible to produce something that can be done.

[0003]

The problem to be solved is that the mere spouting of transparent water by the conventional fountain device is not enough to express the topic and the impression is low. is there.

DISCLOSURE OF THE INVENTION The present invention is directed to a flammable liquid supply system for supplying a flammable liquid and a flame colorant supply system that joins a supply pipe of the combustible liquid supply system to supply a flame colorant. When,
Atomization for ejecting and atomizing the mixed colored fluid of the combustible liquid and the flame colorant, which is provided in communication with the supply pipe downstream from the confluence point of the combustible liquid supply system and the flame colorant supply system It is characterized by comprising a nozzle and an igniting device for igniting the atomized mixed colored fluid ejected from the outlet of the atomizing nozzle, and the flame colored safely by a device having a simple structure and low cost. The purpose was to squirt, enhance expressiveness and impression, and evoke topicality.

[0005]

According to the present invention, the combustible liquid supplied from the combustible liquid supply system and the flame colorant supplied from the flame colorant supply system merge at a confluence point to mix the combustible liquid and the flame colorant. Immediately after the fluid is ejected from the outlet of the atomizing nozzle in the form of an extremely fine rod, the air-fuel ratio becomes an atomized flow within the combustion range. By igniting the atomized flow of the mixed fluid by the ignition device, a flame stream colored by the flame reaction of the flame colorant is generated. By continuing to supply the combustible liquid and the flame colorant from the combustible liquid supply system and the flame colorant supply system and continuously supplying the mixed fluid, colored flame is ejected from the atomizing nozzle. By interrupting the supply of the flame colorant, it is possible to interrupt the colored flame jet and execute the non-colored flame jet. By stopping the supply of flammable liquid, it is possible to stop the flame jet. That is, O of the flammable liquid supply system
Ignition and extinguishing can be freely adjusted by N / OFF control.
By setting the distance from the confluence point of the combustible liquid and the flame colorant to the atomizing nozzle as short as possible, the residual amount of the flame colorant in the supply pipe can be limited to a small amount. Therefore, when a flame color material of a different color is supplied by controlling the switching of the flame color material supply system, it is possible to improve the responsiveness until the next flame stream colored by the flame color material of a different color is ejected.

And a cone portion 41B continuous to the rear end of the columnar portion 41A.
The outer diameter of the columnar portion 41A is set to a value slightly smaller than the diameter of the nozzle opening 40.

As shown in FIGS. 1 and 3, the ignition device 5 is attached to the atomizing nozzle 4 via an arm 9, and a heat generating part 50 is arranged near the nozzle port 40 of the atomizing nozzle 4.

By continuing the supply of the flame coloring material from the second flame coloring material storage tank 30B, a red flame stream is ejected from the atomizing nozzle 4, and the electromagnetic valve 30b is closed to shut off the supply of the flame coloring material. As a result, colored flame ejection can be blocked, and non-colored flame ejection can be ejected. Further, by closing the solenoid valve 20a, it is possible to block the flame ejection which is not colored. That is, by controlling ON / OFF of the solenoid valve 30b, it is possible to selectively perform the flame ejection which is colored red and the flame ejection which is not colored, and the O of the solenoid valve 20a is controlled.

As a result, colored flame ejection can be blocked, and non-colored flame ejection can be ejected. Further, by closing the solenoid valve 20a, it is possible to block the flame ejection which is not colored. That is, by controlling ON / OFF of the solenoid valve 30c, it is possible to selectively perform flame ejection which is colored in blue and flame ejection which is not colored, and the O of the solenoid valve 20a is selected.
