Utility model advantage：
This utility model have the advantages that simple structure, it is easy to use, be easy to directly transform on existing, Er Qie
Solve the bottom-up heat exchange bottom of the tube dust stratification for washing away heat convection pipe of flue gas be difficult to cleaning while, also improve boiler and change
The thermal efficiency and heat utilization efficiency；The easy blockage problem that underlying spout is present is it also avoid simultaneously；Going back additionally by limit switch
Arrange, be effectively guaranteed safety and the service life of soot blower system；Operation steady in a long-term for steam generator system is provided
Reliable guarantee.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
As shown in figure 1, a kind of soot blower of heat convection pipe, it includes arranging blowing pipe 2, the one end of blowing pipe 2 and figure
In the connection of not shown air-blast device, described air-blast device micropulser.
The other end of blowing pipe 2 is stretched in the furnace wall 1 below heat convection pipe 1a, and in its end an elbow 2a is provided with,
Level air outlet upwards is provided with elbow 2a.
A hinged seat 2b is provided with the outer wall of air outlet side, is hinged with hinged seat 2b and air outlet opening
Corresponding matching renovates 3.
One drive link 4 is set, and the inner side of furnace wall 1 is stretched into, at its end in one end of drive link 4 by the through hole 1b on furnace wall 1
Portion is hinged with a connecting rod 4a, and one end of connecting rod 4a is hinged on the connecting seat renovated on 3 so that drive link 4 can pass through connecting rod
4a is pulled and is renovated 3 upsets, opens or close the air outlet on blowing pipe 2.
On the shaft of the drive link 4 at through hole 1b two ends, the leakproof plug of and through hole corresponding matching is further respectively had
Spacing between 5, and described two leakproof plugs 5 is greater than the length of through hole.3 upsets opening is renovated so that drive link 4 is pulled
Or when closing the air outlet on blowing pipe 2, through hole 1b can be effectively blocked, prevent from leaking out.
A gag lever post 7 is provided with the shaft of the drive link 4 of the leakproof plug side in the outside of furnace wall 1, described spacing
The both sides of bar 7 be spaced a distance be respectively equipped with the corresponding matching of gag lever post 7 renovate closing switch 6 and renovate unlatching switch 8, and
