Description

For the outer fire cover of combustion type burner

Technical field

The utility model relates to combustion type burner apparatus, is specifically related to a kind of outer fire cover for combustion type burner.

Background technology

Be generally used at present combustion type burner and comprise outer fire cover and inner fire cover, outer fire cover comprises the outer fire cover body with endoporus, inner fire cover is arranged in the endoporus of outer fire cover body, and outer fire cover and inner fire cover burn the combustion gas of combustion type burner supply to increase respectively the flame holding of combustion type burner.Prior art comprises the outer fire cover body with endoporus for the outer fire cover of combustion type burner, the downside of outer fire cover body is provided with mixing chamber, on outer fire cover body, offer multiple fire output holes, fire output hole is communicated with mixing chamber, in the time of burning, the combustion gas of combustion type burner supply mixes with air in mixing chamber, burn and jet out flames by fire output hole, but the flame that the fire output hole of this spline structure directly sprays is stable not, easily there is the de-fire of part fire output hole or from flame, the stability of flame is poor, and flame disperses, and heating effect is not good.

Utility model content

When the technical problems to be solved in the utility model is to provide a kind of burning, not de-fire is not concentrated heating, the effective outer fire cover for combustion type burner of heat build-up from flame, good, the floating flame cohesive energy flame of steady flame effect.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of outer fire cover for combustion type burner, comprise the outer fire cover body with endoporus, the downside of described outer fire cover body is provided with mixing chamber, the inwall of described outer fire cover body is provided with and reduces step by step from outside to inside the multiple stacked step of arranging, the inwall of outer fire cover body is divided into multiple sidewalls by described stacked step, described sidewall is provided with annular groove, the downside of described outer fire cover body is provided with respectively and annular groove multiple combustion gas through holes unit one to one, described combustion gas through hole unit comprises multiple combustion gas through holes of arranging ringwise, described in any one, one end of multiple combustion gas through holes of combustion gas through hole unit is communicated with mixing chamber respectively, and described in any one, the other end of multiple combustion gas through holes of combustion gas through hole unit is communicated with the inner side of corresponding annular groove respectively.

The utility model has following advantage for the outer fire cover of combustion type burner: the utility model is in working order time, the combustion gas of supply mixes with air in mixing chamber, by after combustion gas through hole, from combustion gas through hole unit, corresponding annular groove ejection forms annular flame, combustion gas is burnt in annular groove, can be anti-anti-avulsion fire or from flame, and annular flame stability is splendid; And because being provided with, the inwall of outer fire cover body reduces step by step from outside to inside the multiple stacked step of arranging, the inwall of outer fire cover body is divided into multiple sidewalls by stacked step, sidewall is provided with annular groove, therefore multiple annular grooves form multiple annular flames of size, height layout straggly, can burn more equably, even flame is concentrated, heating effect excellence, has advantages of that when burning de-fire do not concentrate heating, heat build-up effective from flame, good, the floating flame cohesive energy flame of steady flame effect.

Detailed description of the invention

As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, the present embodiment comprises the outer fire cover body 1 with endoporus 10 for the outer fire cover of combustion type burner, the downside of outer fire cover body 1 is provided with mixing chamber 2, the inwall of outer fire cover body 1 is provided with and reduces step by step from outside to inside the multiple stacked step 3 of arranging, the inwall of outer fire cover body 1 is divided into multiple sidewalls 31 by stacked step 3, sidewall 31 is provided with annular groove 32, the downside of outer fire cover body 1 is provided with respectively and annular groove 32 multiple combustion gas through holes unit one to one, combustion gas through hole unit comprises multiple combustion gas through holes 4 of arranging ringwise, one end of multiple combustion gas through holes 4 of any one combustion gas through hole unit is communicated with mixing chamber 2 respectively, and the other end of multiple combustion gas through holes 4 of any one combustion gas through hole unit is communicated with the inner side of corresponding annular groove 32 respectively.The present embodiment is in working order time, the combustion gas of supply mixes with air in mixing chamber 2, by after combustion gas through hole 4, from combustion gas through hole unit, corresponding annular groove 32 ejections form annular flame, combustion gas is burnt in annular groove 32, can prevent the de-fire of the combustion gas that sprays from combustion gas through hole 4 of part or from flame, and annular flame stability is splendid; And because being provided with, the inwall of outer fire cover body 1 reduces step by step from outside to inside the multiple stacked step 3 of arranging, the inwall of outer fire cover body 1 is divided into multiple sidewalls 31 by stacked step 3, sidewall 31 is provided with annular groove 32, therefore multiple annular grooves 32 form multiple annular flames of size, height layout straggly, can burn more equably, even flame is concentrated, heating effect excellence, has advantages of that when burning de-fire do not concentrate heating, heat build-up effective from flame, good, the floating flame cohesive energy flame of steady flame effect.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
