Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments.
First embodiment
Referring to Fig. 1-4, the ejection structure of this two-chamber direct-injection burner, including injection seat 5 and straight nozzle 6, the injection seat
5 are equipped with center ejector pipe 51 and outer shroud ejector pipe 52, and inlet end is respectively set in their lower end, outlet is respectively set in upper end
End, the straight nozzle 6 of the present embodiment totally two are separately positioned on two inlet ends.
Center ejector pipe 51 and outer shroud ejector pipe 52 are set on injection seat 5, can be the central flame cap (figure of direct-injection burner
Middle unlabelled) and external ring fire cover (unlabelled in figure) individually supplied, supply tolerance bigger, make the integral combustion work(of burner
Rate bigger, and individual straight nozzle is arranged in center ejector pipe and outer shroud ejector pipe, realizes individually mixed gas, gas supply, makes central flame
The burning of lid and external ring fire cover is more abundant, and when firepower is adjusted, central flame cap can individually burn, and the combustion gas regulating effect of burner is more
It is good.
Further, described two straight nozzles 6 are mounted on by straight nozzle holder 61 on two inlet ends, ensure two direct-injections
The matching effect of mouth 6 and two inlet ends then ensures two straight nozzles 6 in center ejector pipe 51 and outer shroud ejector pipe 52
Gas direct-injection effect.
Further, the straight nozzle holder 61 is in straight panel shape, across in center ejector pipe 51 and outer shroud ejector pipe 52
Common transverse axis on, straight nozzle holder 61 and two inlet ends are respectively formed two air inlets, described two straight nozzles 6
Ejection end be respectively facing two outlet sides, i.e., same straight nozzle holder 61 can fix two straight nozzles 6 simultaneously, simplify dress
With effect, straight nozzle holder 61 and two inlet ends are respectively formed two air inlets and disclosure satisfy that air to center ejector pipe 51
With the conveying of outer shroud ejector pipe 52, meet their internal mixed gas, ensures that burning is abundant.
Further, the straight nozzle holder 61 is equipped with several pack support screw holes 611, and holder screw hole 611 passes through screw
It installs and fixes with the jet pipe screw hole 53 being arranged on two inlet ends respectively, installation operation is easy.
Further, the jet pipe screw hole 53 that the holder screw hole 611 is arranged with center ejector pipe 51 installs fixed spacing
H1 installs fixed spacing H2, the technical solution not equal to the jet pipe screw hole 53 that holder screw hole 611 is arranged with outer shroud ejector pipe 52
So that straight nozzle holder 61 and the installation of two ejector pipes is formed error-proof structure, prevents installation from malfunctioning.
Further, described two straight nozzles 6 are installed by screw thread and straight nozzle holder 61, and manufacture craft is simple, cost
