Description
Technical field
The present invention relates to a kind of axial flow blowers that deashing can be carried out to itself blade, belong to wind turbine technical field.
Background technology
In industrial ventilation industry, axial flow blower with the big pressure of air quantity it is small the advantages of, be widely used in factory, warehouse, do
Heating heat dissipation is strengthened in the ventilation in the places such as public room, house, tunnel, in axial flow blower in use, with other wind turbines one
Sample, be susceptible to one it is common the problem of, i.e.,：Fan bearing vibrations are exceeded, when fan bearing vibrations are exceeded, easily cause and
The damage of bearing and blade, the failures such as bolt looseness, casing and air duct damage, seriously jeopardizes the safe operation of wind turbine, and causes
Fan bearing shake exceeded one it is important the reason of be that soot particle in gas is deposited on the non-working surface of blade, i.e. axis stream wind
On the back side of machine blade, when dust stratification has the function that certain weight since impeller rotary centrifugal force is by the dust stratification of a part of block
Blade is thrown away, due to the dust stratification on each blade it is not possible that uniformity, the grey block time assembled or thrown away not necessarily synchronize, is tied
Fruit is because the uneven distribution for leading to Impeller Mass of the dust stratification of blade is uneven, so that the vibrations increase of wind turbine.It is i.e. related
Technology clears up the dust on the upper non-working surface of blade, and preventing the dust of vacuum side of blade from accumulating is highly desirable.
Invention content
The technical problem to be solved in the present invention is to provide a kind of axial flow blowers that deashing can be carried out to itself blade, can remove
The dust of fan blade non-working surface, effectively solves the problems, such as fan bearing shake it is exceeded so that wind turbine is more durable, can with gram
Take the deficiencies in the prior art.
The technical scheme is that：A kind of axial flow blower that deashing can be carried out to itself blade, it includes housing and T shapes
Stent is equipped with motor on T shape stents, motor end install wheel disc, blade is laid on wheel disc, blade just after
More than one stent is installed in the inner walls of side, deashing device is installed on stent, the deashing device includes
The U-typed pipeline being rotated by 90 ° counterclockwise, be connected in the upper end of U-typed pipeline it is funnelform enter tuyere, in U-typed pipeline
Lower end, which is equipped with, cuts a smart figure.
The above-mentioned air outlet diameter cut a smart figure is less than U-typed pipe diameter, whole inclined upward to the left of cutting a smart figure so that
Air outlet face blade and wheel disc link position, during outlet, gas will be flowed along root of blade to blade edge direction.
The prior art compares, and the present invention can carry out itself blade the axial flow blower of deashing, it is in the shell in blade dead astern
More than one stent is installed on internal wall, deashing device is installed on stent, the deashing device includes counterclockwise
The U-typed pipeline being rotated by 90 °, be connected in the upper end of U-typed pipeline it is funnelform enter tuyere, set in the lower end of U-typed pipeline
Having and cut a smart figure, such device can receive sub-fraction air quantity caused by wind turbine by the tuyere that enters with blade face, and then
It by the steering of U-typed pipeline, is blowed from cutting a smart figure to blade non-working surface, the ash on blade inoperative can be removed
Dirt, so as to effectively solve the problems, such as that fan bearing vibrations are exceeded so that wind turbine is more durable；It is funnelform enter tuyere in this way with compared with
Big bore can receive more air quantity so that more strengthen to the wind-force for conveying of cutting a smart figure；
The above-mentioned air outlet diameter cut a smart figure is less than U-typed pipe diameter, and such structure avoids air outlet and also receives wind
Air quantity caused by machine, meanwhile, the Wind Volume that such bore can make the conveying into tuyere come has the impact force of bigger to leaf
Piece non-working surface carries out deashing, there is better ash-removal effect；
Cut a smart figure whole inclined upward to the left so that air outlet face blade and wheel disc link position, during outlet, gas will be along
Root of blade is flowed to blade edge direction, and such air outlet angle can make air quantity from root of blade to blade edge blowing,
Ensure to carry out deashing to the entire non-working surface of blade.
Description of the drawings
Fig. 1 is the attachment structure schematic diagram of the present invention.
Fig. 2 is the structure diagram of deashing device of the present invention.
Specific embodiment
For embodiment 1. as shown in Figure 1, a kind of axial flow blower that deashing can be carried out to itself blade, it includes housing 1 and T

More than one stent 6 is installed on 1 inner wall of housing in 5 dead astern of blade, deashing device is installed on the frame 6, it is described
Deashing device include the U-typed pipeline 7 that is rotated by 90 ° counterclockwise, be connected with funnelform inlet air in the upper end of U-typed pipeline 7
Mouth 8 in fixed U-typed pipeline 7, enters tuyere 8 and 5 face of blade, described in the lower end of U-typed pipeline 7 equipped with cutting a smart figure 9
9 10 diameter of air outlet of cutting a smart figure be less than 7 diameter of U-typed pipeline, 9 whole inclined upwards to the left of cutting a smart figure so that air outlet
10 face blades 5 and 4 link position of wheel disc, during outlet, gas will be flowed along 5 root of blade to 5 edge direction of blade.
