Abstract

The utility model relates to a large torch flame-holding constant open fire burning device which is characterized in that a wind-shielding ring is arranged at the periphery above a blasting cap of a burner; the bottom part of the wind-shielding ring is fixed with the side wall of the blasting cap; a rainproof cap is covered above the wind-shielding ring; the lower part of a flame detecting needle is fixed on the outer wall of a mixing tube by a flame detecting needle bracket; the head part of the flame detecting needle is fixed below the rainproof cap; the lower end of a silicon nitride ignition bar is fixed on the outer wall of the mixing tube by a silicon nitride ignition bar bracket; the head part of the silicon nitride ignition bar is positioned between the rainproof cap and the wind-shielding ring; the lower end of a thermoelectric couple is fixed on the outer wall of the mixing tube by a thermoelectric couple bracket; and the head part of the thermoelectric couple penetrates out from the inner part of the wind-shielding ring and is positioned between the rainproof cap and the wind-shielding ring. The whole head part of the burner is almost wrapped by the wind-shielding ring and the rainproof cap, and is very hidden, thus improving wind-resisting and rainproof performances thereof. The device not only can ignite a main fire burning device, bur also can simultaneously keep burning after a big fire is ignited; and the main flame is not discontinued or extinguished, therefore, the stability and the wind-resisting and rainproof performances of the main fire are increased.

Description

The steady flame Chang Minghuo of large torch burner

Technical field

The utility model relates to a kind of Chang Minghuo burner.

Background technology

The burner head of known naked light burner exposes, and naked light can be seen in the outside, so the anti-rain poor performance of wind resistance, and after the main flame ignition of burner, stability is not good simultaneously, and situations such as being interrupted, extinguishing easily influences result of use.So be badly in need of now existing naked light burner is improved.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides the steady flame Chang Minghuo of a kind of large torch burner, solve the stability of traditional naked light burner and the technical problem of the anti-rain poor performance of wind resistance.

The technical scheme that its technical problem that solves the utility model adopts is:

The steady flame Chang Minghuo of a kind of large torch burner is formed burner by nozzle, air regulating board, injector, mixing tube, igniter cap, and there is the igniting pin at the burner center, and injector is communicated with mixing tube, it is characterized in that:

Around the igniter cap top of described burner wind loop is arranged, the bottom of wind loop and igniter cap sidewall are fixed, the top of wind loop is covered with shading rain cap, the bottom of flame detection pin is detected needle rack by flame and is fixed on the outer wall of mixing tube, the head that flame detects pin is fixed in below the shading rain cap, the lower end of silicon nitride fire rod is fixed on the outer wall of mixing tube by silicon nitride fire rod support, the head of silicon nitride fire rod is between shading rain cap and wind loop, the lower end of thermocouple is fixed in by the thermocouple support on the outer wall of mixing tube, and the head of thermocouple passes from wind loop inside, between shading rain cap and wind loop.

Angle between described injector and the mixing tube center line is 30 °～90 °.

The beneficial effects of the utility model are as follows:

Main effect of the present utility model is to ignite and the retention flame, and what it adopted is completing combustion atmospheric burning type mode, and burning is complete, stable.The utility model is provided with wind loop and shading rain cap, and wind loop and shading rain cap almost all wrap burner head hold together, and naked light be can't see in the outside, and is very hidden, has therefore improved its anti-rain performance of wind resistance.The utility model main fire burns device that not only can ignite can keep burning simultaneously always after big fire is lighted, make main flame can not be interrupted, extinguish, and has increased the stability and the anti-rain of wind resistance of main fire.
