The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, be the structural representation of an embodiment of secondary wind direction adjusting device under the utility model W type flame furnace arch.Fig. 2 is the schematic diagram of the LOOK RIGHT degree of the present embodiment.In the present embodiment, under W type flame furnace arch, the secondary wind direction adjusting device comprises: deflector 2, support 3, connecting rod and riser 11 and adjusting portion 6.In conjunction with installation site schematic diagram shown in Figure 3, can see that deflector 2, support 3, connecting rod and riser 11 all are arranged in the secondary air box 15 outside the water-cooling wall 13 of burner hearth 16 of W type flame furnace, support 3 is fixed in secondary air box 15, and relative motion does not occur.In secondary air box 15, be provided with air distribution plate 14, on air distribution plate 14, evenly be laid with a plurality of air vents, can make air pass through air distribution plate 14 and evenly pass through.As can see from Figure 3, deflector 2 and support 3 etc. is arranged between water-cooling wall 13 and air distribution plate 14, and adjusting portion 6 is arranged on outside secondary air box, can adopt the structure on the outer wall that in Fig. 3, adjusting portion 6 is fixed on to secondary air box 15 by holder 7.
In the present embodiment, be arranged on the outer adjusting portion of secondary air box and can drive the hinge rotation of deflector on support by control link displacement in the longitudinal direction, and then the angle of Secondary Air is adjusted at the angle of inclination that changes deflector, to adapt to different combustion conditions, therefore not only very simple in realization, regulate also very conveniently, and can not be subject to the restriction of secondary air box structure.
Structure for the deflector that multi-disc is arranged, the structure realization that many group connecting rods and riser coordinate can be set, but this will certainly increase the complexity of structure, therefore Fig. 1 embodiment has provided the way of realization that a kind of structure is more succinct, be about to deflector 2 and be divided at least one master control deflector and a plurality of driven deflector, one end of connecting rod is fixedly connected with the master control deflector by riser 11, and driven deflector does not connect riser, is not subjected to directly affecting of connecting rod.One end of master control deflector and an end of driven deflector all are hinged on support 3, in order to realize the adjusting of driven deflector angle, also need that the other end of master control deflector and the other end of driven deflector all are hinged to one and be connected on hinge 1, driven like this deflector just can be along with the master control deflector hinge on support 3 rotate and be driven synchronously and rotate.
In order to make the more smooth of driven deflector running, the master control deflector can be arranged to parallel with driven deflector, and the hinge line on support 3 is parallel with the hinge line on connecting hinge 1, so just formed parallelogram, when having fixed one side of support 3 correspondences, by driving the corresponding one side of master control deflector, rotate certain angle with respect to support 3, just can make the driven deflector parallel with the master control deflector also rotate identical angle.
When adjusting portion is carried out the adjusting on length direction to connecting rod, in fact in connecting rod motion process in the longitudinal direction, also have perpendicular to the small sway on length direction and move, if limiting rod can not swing, can cause connecting rod, the distortion of riser or deflector or infringement, in order to address this problem, can adopt the scheme shown in Fig. 1 embodiment, be about to connecting rod and be made as first connecting rod 4 and second connecting rod 5 two parts, and an end of an end of first connecting rod 4 and second connecting rod 5 is undertaken hinged by bearing pin 8, the other end of first connecting rod 4 is fixedly connected with deflector 3 by riser 11, and the other end of second connecting rod 5 is connected with adjusting portion 6.Like this, first connecting rod 4 just can swing by a small margin around bearing pin 8, and avoids the problems such as the distortion of connecting rod, riser or deflector or infringement.
In another embodiment, as shown in Figure 4, can also save second connecting rod 5, only retain first connecting rod 4, directly first connecting rod 4 is connected on adjusting portion 6, and that adjusting portion 6 is arranged on hinged holder 8 ' is upper, first connecting rod 4 and adjusting portion 6 can be together swing by a small margin around the hinge on holder 8 ' like this,, and avoid the problems such as the distortion of connecting rod, riser or deflector or infringement.
Adjusting portion 6 can adopt manual adjustments section, also can adopt motor-driven adjusting portion, and concrete structure can adopt the mode of screw thread transmission etc., rotates adjusting portion by manual or motor-driven mode, converts the rotation of adjusting portion to connecting rod motion in the longitudinal direction.Concrete structure has just no longer described in detail.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
