Abstract
The utility model discloses a kind of width fan blade of double-vane three, including blade cylindrical section, filter blade section and blade aerodynamic section, the blade cylindrical section, filter blade section and blade aerodynamic section are sequentially connected integral, the blade aerodynamic section end is provided with first pneumatic section of blade and second pneumatic section of blade, first pneumatic section of blade includes a vane tip portion, and second pneumatic section of blade includes two vane tip portions.The width fan blade of a kind of double-vane three provided by the utility model, it is simple in construction, point is added by the end to blade aerodynamic section, so that fan blade is not in the case where increasing, the effect that air quantity is greatly increased is realized.
Description
Technical field
The utility model is related to Fan Equipment technical field, and in particular to a kind of width fan blade of double-vane three.
Background technology
Blower fan, purposes is exactly the equidirectional air-flow of axle with fan blade widely, such as electric fan, and outdoor machine of air-conditioner fan is just
It is that axle stream mode runs blower fan, why is referred to as " axial-flow type ", is that axial fan leads to because gas flows parallel to fan shaft
It is commonly used in the occasion that traffic requirement is higher and pressure requirements are relatively low；Many large fans are applied to coal yard or steel plant at present, use
In to production on-site progress air draft blowdown；Fan blade is the key core part of blower fan, it is good design, reliable quality
It is to ensure the determinant that unit normal table is run with superior performance；The fan blade used at present is all one chip,
Thus on air quantity is provided can defect, and the size dimension for increasing blade can solve this problem, but blindness is exaggerated
The size of blade, can increase the load of blower fan, and the cost of blower fan can be more expensive, increase entreprise cost.
Utility model content
The purpose of this utility model provides a kind of width fan blade of double-vane three, solves one in above-mentioned prior art problem
Or it is multiple.
According to a kind of width fan blade of double-vane three of the present utility model, including blade cylindrical section, filter blade section and blade
Pneumatic section, the blade cylindrical section, filter blade section and blade aerodynamic section are sequentially connected integral, the blade aerodynamic section end
Provided with first pneumatic section of blade and second pneumatic section of blade, first pneumatic section of blade includes a vane tip portion, described
Second pneumatic section of blade includes two vane tip portions.
The width fan blade of a kind of double-vane three provided by the utility model, it is simple in construction, pass through the end to blade aerodynamic section
Portion adds point, so that fan blade is not in the case where increasing, realizes the effect that air quantity is greatly increased.
In some embodiments, first pneumatic section of blade is located at second pneumatic section of vane nose.
In some embodiments, the vane tip portion of first pneumatic section of blade is located at second pneumatic section of blade
Vane tip portion in the middle of.
In some embodiments, the height in the vane tip portion of first pneumatic section of blade is pneumatic less than described second
The vane tip portion of section blade.
Brief description of the drawings
Fig. 1 is a kind of a kind of side structure schematic diagram of the width fan blade of double-vane three of embodiment of the present utility model；
Fig. 2 is a kind of a kind of positive structure schematic of the width fan blade of double-vane three of embodiment of the present utility model.
Embodiment
With reference to Figure of description, the utility model is described in more detail.
As shown in Fig. 1 to Fig. 2, a kind of width fan blade of double-vane three, including blade cylindrical section 1, filter blade section 2 and leaf
Pneumatic section 3 of piece, blade cylindrical section 1, filter blade section 2 and blade aerodynamic section 3 are sequentially connected integral, blade cylindrical section 1, blade
The connected mode of fillter section 2 and blade aerodynamic section 3 can be integrally formed to pour to form or three sections are welded,
By welding, then solder joint is parallel with metal surface is defined in this way；The end that blade aerodynamic section 3 is not connected with filter blade section 2 is provided with
In first pneumatic section of blade 31 and second pneumatic section of blade 32, the present embodiment, first pneumatic section of blade 31 includes a blade point
End, second pneumatic section of blade 32 includes two vane tip portions.
First pneumatic section of blade 31 is arranged at second pneumatic section of front end of blade 32, the vane tip of first pneumatic section of blade 31
Portion is in the middle of the vane tip portion of second pneumatic section of blade 32, thus two pneumatic section of blades then show three width blades point
End, blade in the case of not increasing there is provided air quantity be more than original single width blade produced by air quantity；First pneumatic section of leaf
The height in the vane tip portion of piece 31 is less than the vane tip portion of second pneumatic section of blade 32, then when rotated, work is more for blade
It is stable.
The width fan blade of a kind of double-vane three provided by the utility model, it is simple in construction, pass through the end to blade aerodynamic section
Portion adds point, so that fan blade is not in the case where increasing, realizes the effect that air quantity is greatly increased, reduction
The burden of enterprise.
Described above is only preferred embodiment of the present utility model, it is noted that to those skilled in the art,
On the premise of the utility model creation design is not departed from, some similar modification and improvement can also be made, these should also be regarded
Within protection domain of the present utility model.
