Description
Technical field
A kind of tracks of device is the utility model is related to, being filled from motion tracking for air preheater air leakage rate is reduced more particularly, to a kind of
Put.
Background technology
The air preheater that country's Large-scale machine set uses at present is radially close using hot junction installation automatic tracking system, hot end of rotor
The gap of envelope increases and causes the increase for the area that leaks out, curved under automatic control system of leaking out control fanning strip, tracks the heat of rotor
State is deformed to reduce the area that leaks out, so as to reduce inleakage.Its technological improvement is quite ripe, tends to bottleneck, or using laser
Structure or soft sealing structure, air leak rate of air curtain can be controlled in 6~7% or so during unit high load capacity.But since general cold end sector plate is adopted
With fixed mechanism, fail to automatically adjust with load conversion, therefore in low load stage, the air leak rate of air curtain of air preheater more than 9%,
Primary air fan, give, air-introduced machine power consumption also increases therewith.Therefore cold end is further transformed, leaked out to reduction, to improving boiler
Whole efficiency, reduction unit coal consumption play the role of positive.
Utility model content
The purpose of this utility model is exactly to overcome the problems of the above-mentioned prior art and providing one kind can effectively control
The autotracker of the reduction air preheater air leakage rate in gap processed.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of autotracker for reducing air preheater air leakage rate, including：
The Promotion From Within bar being connected with fanning strip the inner,
The exterior lift lever being connected with fanning strip outer end,
The linkage of Promotion From Within bar and exterior lift lever is connected,
The access point of fanning strip electrical header, is arranged on exterior lifting rod end.
As preferred embodiment, linkage includes：
Promotion From Within bar supporting rod, and the perpendicular connection of Promotion From Within bar,
Promotion From Within bar rotation axis, equipped with two, is connected to the both sides of Promotion From Within bar supporting rod,
Exterior lift lever supporting rod, and the perpendicular connection of exterior lift lever,
Exterior lift lever rotation axis, equipped with two, is connected on exterior lift lever supporting rod,
Connect the connecting rod of Promotion From Within bar rotation axis and exterior lift lever rotation axis.
As more preferred embodiment, the access point of fanning strip electrical header is arranged on two exterior lift lever rotation axis
Between.
As more preferred embodiment, exterior lift lever is equipped with two, is arranged on the two of exterior lift lever supporting rod
End.
As more preferred embodiment, Promotion From Within bar rotation axis is movably connected on the girder steel of lower part, and along connection
Point rotation.
As more preferred embodiment, exterior lift lever rotation axis is movably connected on another lower part girder steel, and
Rotated along tie point.
Compared with prior art, the utility model can effectively control fanning strip and diaphragm seal gap, while will not
Fanning strip is caused to damage, in ten thousand load air leak rate of air curtain≤7% of air leak rate of air curtain≤4%, 50 at full capacity.At the same time also reduce primary air fan,
Send, air-introduced machine power consumption.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1- Promotions From Within bar, lift lever outside 2-, 3- electrical headers access point, 4- Promotion From Within bars supporting rod, in 5-
Portion's lift lever rotation axis, lift lever supporting rod outside 6-, lift lever rotation axis outside 7-, 8- connecting rods, lower part girder steel, 10- in 9-
Outer lower part girder steel.
Embodiment
The utility model is described in detail with reference to specific embodiment.Following embodiments will be helpful to this area
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These belong to the scope of protection of the utility model.
Embodiment
A kind of autotracker for reducing air preheater air leakage rate, its structure is as shown in Figure 1, including inner even with fanning strip
The Promotion From Within bar 1 connect, the exterior lift lever 2 being connected with fanning strip outer end, connection Promotion From Within bar 1 and exterior lift lever 2
The electrical header access point 3 of linkage and fanning strip electrical header, is arranged on exterior lifting rod end.Wherein, the connecting rod machine of use
Structure includes：Promotion From Within bar supporting rod 4, and 1 perpendicular connection of Promotion From Within bar, Promotion From Within bar rotation axis 5, equipped with two,
The both sides of Promotion From Within bar supporting rod 4 are connected to, exterior lift lever supporting rod 6 is exterior with exterior 2 perpendicular connection of lift lever
Lift lever rotation axis 7, equipped with two, is connected on exterior lift lever supporting rod 6, and connection Promotion From Within bar rotation axis 5 and
The connecting rod 8 of exterior lift lever rotation axis 7.
Promotion From Within bar rotation axis 5 is flexibly connected on interior lower part girder steel 9, and can be rotated along tie point.Outside lifting
Bar rotation axis 7 is flexibly connected on outer lower part girder steel 10, and can be rotated along tie point.Interior lower part girder steel 9 and outer lower part girder steel
In arranged in parallel between 10.Exterior lift lever 2 is equipped with two, is arranged on the both ends of exterior lift lever supporting rod 6.Electrical header
Access point 3 is arranged between two exterior lift lever rotation axis 7.
When the utility model is used, the displacement that Promotion From Within bar is eventually converted into by linkage drives cold end fan-shaped
Plate moves, and makes interior outer bar displacement proportional, so that fanning strip is inner to keep opposing stationary；System is equipped with and controls on the spot
Cabinet, control logic write-in are carried in PLC, and electrical header carries torque setting, sets peripheral hardware scale can on torque alarm and connecting rod excessively
See observation fanning strip change location, ensured that alarm can be automatically springed open and triggered during torque.
