Embodiment 1

[0018] Figure 1, figure 2 As shown, the embodiment of the present invention provides a kind of flame injection device, comprises the gas storage tank 1 that is connected with the flame spray gun 7 through the gas pipe 2, and the permanent ignition source 8 that is positioned at the outlet of the flame spray gun 7, the gas storage tank 1 and the flame spray gun 7 The flame spray gun 7 is provided with a regulating valve 3, an electric valve 4, a flame arrester 5, and a check valve 6 in sequence. The flame spray gun 7 has a channel with a two-stage zoom structure, which is used to accelerate the high-pressure gas delivered by the gas storage tank 1. An unburned combustible gas mass is formed; the outlet of the flame spray gun 7 also has a blockage 71 capable of adjusting the size of the unburned combustible gas mass. The combustible gas flows out from the gas storage tank 1, passes through the regulating valve 3, the electric valve 4, the flame arrester 5, and the check valve 6 ...

Abstract

The invention discloses a flame spraying device, comprising a gas storage tank and at least one flame spray gun which are connected with each other by a fuel gas pipe, and an ever-burning ignition source which is arranged at the outlet of the flame spray gun. An adjusting valve, an electric valve, a flame arrester and a check valve are sequentially arranged between the gas storage tank and the flame spray gun; the flame spray gun is provided with a passage which has at least one-step scaling structure which is used for accelerating the inflow high-pressure fuel gas and forming an unburned flammable air mass; the outlet of the flame spray gun is also provided with a stopper which can adjust the size of the unburned flammable air mass. The flame spraying device which is provided by the invention can spray a fireball with larger diameter and higher spraying height by the control of the electric valve and the passage of the flame spray gun scaling structure, can spray flames with other complex types, and can meet the requirement of landscape effect.

Description

technical field [0001] The present invention relates to a flamethrowing device for landscaping or show use. Background technique [0002] In the field of artificial landscape, the fire moment is one of the most widely used artificial landscapes. In order to obtain a more special landscape effect, it is sometimes necessary to form a fireball that rises from the nozzle and rises into the air, thus greatly enhancing the flame landscape effect. If the equipment is combined with the fountain , water curtain or other landscape equipment can be coordinated to form a special landscape where water and fire blend. [0003] Existing flame injection devices generally can only spray fireballs with a small diameter, and the height of the spray is also very limited. Generally, the diameter of the sprayed fireball is tens of centimeters, and the height from the nozzle is about 1 to 2 meters. . It is even more difficult to produce flames of other complex shapes, which are far from meeting ...
