Description
Technical field
The present invention relates to a kind of spout swing mechanism, belong to boiler technology field.
Background technology
In the actual motion of boiler, due to boiler load change, combustion conditions adjustment, pollutant emission control, prevention
The needs of the operating modes such as coking, water wall high temperature corrosion, burner nozzle needs to carry oscillating function, so that primary and secondary air air-flow
Direction adjusts in good time, is conveniently adjusted furnace flame centre height, regulation gas temperature windage etc..
Traditional boiler-burner spout is swung uses planar linkage mechanism more, and swinging mode using quadrangle realizes pendulum
It is dynamic.Some intrinsic deficiencies be present in this mode：
1st, for highly less spout, connecting rod there are problems that colliding with spout, and this just needs to open in spout position of colliding
Breach avoids connecting rod, reduces spout intensity；
2nd, when spout is swung, in one direction, connecting rod can be close towards burner hearth direction, into hot environment, the easily company of reduction
The bar life-span；
3rd, the restriction of the tie point radius of gyration on spout is limited to, spout is limited to a certain minimum value, mutually tackles wind
Case design, which exists, to be restricted.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind not to influence spout intensity and bellows design, and service life is grown
, the transmission mechanism that boiler-burner spout is swung can be achieved.

The swing arm is connected by axle sleeve through the mounting hole on the swing arm and the circular hole on the inside connecting rod with main rocker.
Further, can be free in mounting hole of the pin sleeve on the swing arm and the circular hole on the inside connecting rod
Rotate.
Further, the outside connecting rod of main rocker is acted on by external force, makes its rotation；It is interior under the drive of master connecting-rod
Connecting rod rotates simultaneously, and drives pin sleeve to circle；Slided in the mounting hole of pin sleeve on a swing arm, drive swing arm
Rotated with central rotating shaft of the spout together around spout, so as to realize the swing of spout.
Further, turning for the two is changed by adjusting the position for the pin sleeve for connecting the swing arm and inside connecting rod
Dynamic radius, during so as to realize that spout swings a certain angle, pin sleeve deviates the height-adjustable of bellows center line.
Preferably, the attachment means include transiting rod, and transiting rod is fixedly connected by itself support with the bellows, and
Can be around itself holder pivots；Transiting rod both ends are equipped with circular hole, and two pin sleeves are each passed through the circular hole at transiting rod both ends
And it is connected respectively with the mounting hole on inside connecting rod, the swing arm.
It is highly preferred that described inside connecting rod one end connects the master connecting-rod, the inside connecting rod other end is provided with waist-shaped hole；One
Pin sleeve is through the mounting hole and the circular hole of described transiting rod one end on the inside connecting rod, by the inside connecting rod and the transiting rod
One end connection；Another pin sleeve is through the mounting hole and the circular hole of the transiting rod other end on the swing arm, by institute
The other end that swing arm is stated with the transiting rod is connected.
It is highly preferred that described two pin sleeves are free to rotate.
Further, in use, acting on the outside connecting rod of main rocker by external force, its rotation is made；In the drive of master connecting-rod
Under, inside connecting rod rotates simultaneously, and drives the pin sleeve being connected with inside connecting rod to circle, and the pin sleeve is simultaneously on inside connecting rod
Mounting hole in slide, drive transiting rod rotate；Transiting rod drives another pin sleeve being connected with its other end to rotate, another
Slided in the mounting hole of individual pin sleeve on a swing arm simultaneously, so as to drive swing arm and spout to turn together around spout central rotating shaft
It is dynamic, realize the swing of spout.
Compared with prior art, spout swing mechanism provided by the invention has the advantages that：
1st, spout swing arm is located on rear side of spout, away from burner hearth hyperthermia radiation area, long lifespan, is not easy bite；
2nd, drive mechanism is simple, and connector is few, and reliability is high, easily fabricated processing and installation；
3rd, spout oscillatory forces brachium, the active force of application can be greatly reduced, plays labor-saving effect；
4th, spout is not influenceed by swing arm, and spout intensity and height etc. will not reduce, and is mutually tackled bellows design and is also not present
Influence.
