Background technology
Existing a kind of burner, comprise furnace head base, external ring fire cover and interior ring fire cover, furnace head base is by being positioned at the outer burned gas base of outer ring and being positioned at center burned gas base and forming, hole centered by the centre of external ring fire cover, external ring fire cover offers the groove that fires, and the periphery wall of interior ring fire cover offers fire output hole, external ring fire cover lid is outside on burned gas base, interior ring fire cover covers on interior burned gas base, and the upper surface of external ring fire cover is horizontal structure, and the groove that fires then is vertically installed in the upper surface of external ring fire cover.Adopt the burner of this structural design, being heated of the bottom of a pan is uneven, and meanwhile, flame is subject to firing the restriction of slot length, and the effective area of flame is less, and firing rate is slow.
Moreover toward the outer side, also toward the outer side, so, the area that flame contacts with the bottom of a pan is little, and burned flame is not fully used, and the thermal efficiency is low, and firing rate is slow for the flame sprayed from interior ring fire cover for the fire output hole on interior ring fire cover periphery wall.
Summary of the invention
The purpose of this utility model is: provide that a kind of firing rate is fast, the thermal efficiency is high, simultaneously the scarf burner that is heated evenly of the bottom of a pan.
The utility model solves the technical scheme that its technical problem adopts: a kind of scarf burner, comprise furnace head base, external ring fire cover and interior ring fire cover, furnace head base is by being positioned at the outer burned gas base of outer ring and being positioned at center burned gas base and forming, hole centered by the centre of external ring fire cover, external ring fire cover offers the groove that fires, the periphery wall of interior ring fire cover offers fire output hole, external ring fire cover lid is located on outer burned gas base, interior ring fire cover lid is located on interior burned gas base, the upper surface of described external ring fire cover tilts to the opposite direction of centre bore, the inner of external ring fire cover is provided with the extension that a circle tilts to centre bore direction, fire groove for groove of cutting sth. askew, cut sth. askew the inner of groove extends to extension place, the cut sth. askew angle of inclination of groove is 28 ~ 32 degree, the periphery wall of interior ring fire cover is inclined upwardly, the angle of inclination of periphery wall is 20 ~ 24 degree.
As preferably, described in the cut sth. askew angle of inclination of groove be 29.5 degree, the angle of inclination of periphery wall is 22 degree.
As preferably, the angle of inclination of described external ring fire cover upper surface is 20 ~ 25 degree, and the angle of inclination of extension is 40 ~ 43 degree.
As preferred further, the angle of inclination of described external ring fire cover upper surface is 12 degree, and the angle of inclination of extension is 41.5 degree.
The utility model compared with prior art, has the following advantages:
One, the utility model scarf burner is designed to by the groove that will fire groove of cutting sth. askew, and under the prerequisite not increasing external ring fire cover area, can lengthen the length of the groove that fires, increase the area that fires of flame, thus effectively improve firing rate; Meanwhile, the angle of inclination of groove of cutting sth. askew is designed to 28 ~ 32 degree, the flame of the groove that fires under this angle of inclination ejection is the most stable, and the bottom of a pan is heated evenly.
Two, the inner of external ring fire cover is provided with the extension that a circle tilts to centre bore direction, makes also can jet out flames in extension, further increases the length of the groove that fires, and increases the area that fires of flame; Extension tilts to centre bore direction, and meanwhile, the upper surface of external ring fire cover tilts to the opposite direction of centre bore, so, flame can not only spray to the center of external ring fire cover, also can spray to the outside of external ring fire cover simultaneously, make being heated of the bottom of a pan more even, firing rate is faster.
Three, the periphery wall of interior ring fire cover is inclined upwardly, and the fire output hole offered thereon is also inclined upwardly, and flame sprays to the oblique upper of fire output hole, so, greatly can increase the contact area in flame and the bottom of a pan, the flame of ejection can be fully used, and effectively improves firing rate and the thermal efficiency; Meanwhile, the angle of inclination of periphery wall is designed to 20 ~ 24 degree, under this angle of inclination, the flame of fire output hole ejection is the most stable, and the bottom of a pan is heated evenly.
Further, the top periphery wall of described interior ring fire cover being positioned at fire output hole is provided with a circle stable flame hole.Adopt this structural design, can play the effect of steady flame to the flame sprayed from fire output hole, make flame more stable, heating effect is better.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model scarf burner.
Fig. 2 is the planar structure schematic diagram of the utility model scarf burner.
Shown in figure: 1, the inclination angle beta of burned gas base 2, external ring fire cover 3, interior ring fire cover 4, centre bore 5, the groove 6 that fires, fire output hole 7, extension 8, stable flame hole θ, groove of cutting sth. askew, the angle of inclination ε of periphery wall, the angle of inclination δ of external ring fire cover upper surface, the angle of inclination of extension in furnace head base 1.1, outer burned gas base 1.2.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of scarf burner, furnace head base 1, external ring fire cover 2 and interior ring fire cover 3 is comprised.Furnace head base 1 is by being positioned at the outer burned gas base 1.1 of outer ring and being positioned at center burned gas base 1.2 and forming.External ring fire cover 2 is in circular, and centered by its centre hole 4.External ring fire cover 2 offers the groove 5 that fires, the periphery wall of interior ring fire cover 3 offers fire output hole 6.External ring fire cover 2 lid is located on outer burned gas base 1.1, and interior ring fire cover 3 lid is located on interior burned gas base 1.2.The upper surface of external ring fire cover 2 tilts to the opposite direction of centre bore 4.The inner of external ring fire cover 2 is provided with the extension 7 that a circle tilts to centre bore 4 direction.Fire groove 5 for groove of cutting sth. askew, and the inner of groove of cutting sth. askew extends to extension 7 place.The tilt angle theta of groove of cutting sth. askew is 28 ~ 32 degree.The periphery wall of interior ring fire cover 3 is inclined upwardly, and the inclination angle beta of periphery wall is 20 ~ 24 degree.
