Described waling stripe comprises the many branch connecting rods that master connecting-rod is connected with master connecting-rod with an end, the other end is connected with the turning cylinder of each horizontal blade.
The inventor has abandoned original mode that realizes secondary gas flow level or vertical deflection by the spout swing through research for many years, horizontal blade and vertical vane are set in the leading portion of overfire air port, utilize the swing of horizontal blade, substitute the horizontal hunting of original spout, utilize the vertical oscillation of vertical vane, substitute the vertical oscillation of original spout, can realize equally that by controlling corresponding horizontal or vertical blade respectively secondary general mood flows the purpose of horizontal or vertical deflection.The front and back position that described horizontal blade and vertical vane are positioned at the overfire air port leading portion is not particularly limited, and can be the close spout front end of horizontal blade, also can be that vertical vane is near the spout front end.
It is multiple to realize that through transmission mechanism the mode of blade level or vertical oscillation has by drive unit, not narration one by one here, and those skilled in the art are appropriate design as required.The structure that can exemplify out preferred control horizontal blade swing is: first pull bar, one end connects through the crank and first driving shaft, utilize crank that the rotatory force of first driving shaft is become and drive the axially movable power of first pull bar, sleeve joint in the other end of first pull bar, make this axial moving force pass to horizontal blade by universal joint through connecting rod, because first pull bar and horizontal blade be arranged in parallel, therefore universal joint can pass to one of horizontal blade through connecting rod and involve power, make blade along its rotating shaft direction horizontal hunting, make secondary wind realize horizontal deflection; The structure that can exemplify out preferred control vertical vane swing is: the two ends lease making crank of second pull bar is connected with the turning cylinder of second driving shaft and vertical vane, utilize crank that the rotatory force of second driving shaft is become and drive the axially movable power of second pull bar, in like manner, utilize crank also the axially movable power of second pull bar can be passed to the turning cylinder of vertical vane, vertical vane is swung with the turning cylinder center.
Horizontal blade and vertical vane can be provided with multi-disc, under the little situation of shaking moment, improve the amplitude of fluctuation of control secondary wind, lease making divides connecting rod to be connected with master connecting-rod separately between each turning cylinder of a plurality of horizontal blades, drive arbitrary horizontal blade swing like this, because the existence meeting of connecting rod is passed to other horizontal blade simultaneously with this rotatory force; The control principle same level blade of multi-disc vertical vane.Turning cylinder of the present invention can connect drive unit, also can adopt manual mode to regulate, and is very flexible.
Beneficial effect:
1. the present invention's spout simple in structure, secondary wind is motionless fully, and the form that adopts built-in blade is controlled the horizontal or vertical deflection of secondary wind, make the amplitude of fluctuation of wind be subjected to two side walls to allow pipe limit more greatly and not, simple in structure, easy to operate, reduced equipment investment and maintenance cost, improved the service life of equipment.
2, adopt the spout dead beat, and the structure of built-in blade oscillating has thoroughly solved the stuck and air leakage phenomena that the spout swing brings, the control of secondary wind is more accurate.
3, because spout is motionless, not limited by burner structure, when 200MW and following unit adopted housing to fill to water the material feeding structure, advantage was more obvious.
4, swing more flexibly, light and handy, shaking moment is all less than 50Nm, automatic or manual control all can, more simple.
