Description
Technical field
The utility model relates to industrial ventilation technical field, particularly relates to a kind of draught fan impeller.
Background technology
At present draught fan impeller on the market can be generally divided into two types: conventional centrifugal impeller and multileaf type impeller.
The blade wheel structure of conventional centrifugal is relatively simple, will several blades be uniformly mounted on impeller installing plate, weak point
Being, the height of blade, restricted width, because in the course of work of blower fan, height and the width of blade are bigger, and impeller rotates
The air quantity producing is bigger, but produces corresponding pressure simultaneously to blade and also can synchronize to increase, longtime running then can make blade and
The junction of installing plate produces tired and may be impaired, causes shorten service life.The structure of multileaf type impeller be then
Installing plate extension installs the blade that quantity is more more than conventional centrifugal impeller, width is narrower, and installs at the top of blade again
One circular upper cover is fixed, and the deficiency of this structure is, owing to the structure of multileaf type impeller is more more multiple than conventional centrifugal
Miscellaneous, required parts are also more, and impeller overall weight can be caused to increase, and increase load and the energy consumption of motor.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of rational in infrastructure, lightweight and
The draught fan impeller of good heat dissipation effect.
The purpose of this utility model realizes by the following technical solutions:
A kind of draught fan impeller, including installation chassis, axle sleeve, annular reinforcing plate, some primary blades and some back blades, axle sleeve
Having base plate and by the sleeve column extending perpendicularly out in base plate, installation chassis, axle sleeve and annular reinforcing plate are coaxial, and installation chassis is located on
Sleeve column periphery, one end of primary blades is fixed on the surface towards annular reinforcing plate for the installation chassis, and the other end is fixed on annular reinforcement
On plate, back blades is fixedly arranged on the surface that installation chassis leaves annular reinforcing plate.
Preferably, described installation chassis is provided with some hollow holes.
Preferably, described primary blades one end is riveted on installation chassis, the other end by way of buckle with annular reinforcing plate
Engaging.
Preferably, described primary blades is spacedly distributed around the circumference of installation chassis.
Preferably, described some hollow holes are spacedly distributed around the circumference of installation chassis, and each hollow hole is positioned at adjacent
Primary blades between.
Preferably, described some back blades are spacedly distributed around the circumference of installation chassis, and each back blades is positioned at hollow hole
Edge, and back blades and primary blades position one_to_one corresponding.
Preferably, described back blades is one-body molded with installation chassis.
Preferably, described installation chassis arches upward from inside to outside, and the inner bottom surface at installation chassis forms ring-shaped depression, is installing
The outer bottom on chassis forms the portion that arches upward.
Preferably, rounding off between the inner bottom surface of described installation chassis and the bottom surface of ring-shaped depression.
Compared to existing technology, the beneficial effects of the utility model are: by using hollow hole structure on installation chassis,
Alleviate the weight of impeller, reduce the load of blower fan；By using annular reinforcing plate, primary blades is reinforced, enhance leaf
The steadiness of wheel, extends service life；Owing to impeller steadiness strengthens, and then bigger blade can be used, increase air-out
Amount.

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further:
As shown in Figure 1, Figure 2 and Figure 3, a kind of draught fan impeller, including installation chassis the 1st, axle sleeve the 2nd, annular reinforcing plate is the 3rd, some
Primary blades 4 and some back blades 5, axle sleeve 2 has base plate 8 and by the sleeve column 9 extending perpendicularly out in base plate 8, installation chassis the 1st, axle sleeve 2
Coaxial with annular reinforcing plate 3, installation chassis 1 is located on sleeve column 9 periphery, and one end of primary blades 4 is fixed on installation chassis 1 towards ring
The surface of shape reinforcing plate 3, the other end is fixed in annular reinforcing plate 3, and back blades 5 is fixedly arranged on installation chassis 1 and strengthens away from annular
The surface of plate 3.
Preferably, sleeve column 9 is sheathed on the rotating shaft of blower fan, thus transmits power and then impeller rotation, the base plate 8 of blower fan
It is fixedly arranged on the center of installation chassis 1, is riveted on the center of installation chassis 1, naturally it is also possible to be that welding waits other knots
Conjunction mode；Installation chassis 1 and annular reinforcing plate 3 are coaxial, are beneficial to realize that the equilibrium of primary blades 4 is installed；One end of primary blades 4 is fixed
It in installation chassis 1 towards the surface of annular reinforcing plate 3, is riveted on installation chassis 1, it is also possible to be other combinations such as welding,
The other end is fixed in annular reinforcing plate 3, combines in a snap-in manner, or can be one-body molded, as this construction increases master
The holding capacity of blade 4, therefore can improve height and the width of primary blades 4, thus increase air output；Meanwhile, annular reinforcing plate 3
Lot of materials can be saved, be beneficial to improve radiating efficiency；Back blades 5 is fixedly arranged on the table that installation chassis 1 leaves annular reinforcing plate 3
Face, is beneficial to the heat radiation to blower fan.
Additionally, installation chassis 1 is provided with some hollow holes 6, and be positioned between adjacent primary blades 4, be beneficial to save material,
Mitigate weight and then mitigate blower fan load.
Preferably, primary blades 4 is spacedly distributed around the circumference of installation chassis 1, and therefore primary blades 4 produces in running
Part air quantity reach blower motor side, beneficially motor radiating by hollow hole 6.
Equally, back blades 5 is spacedly distributed around the circumference of installation chassis 1, and each back blades 5 is positioned at the edge of hollow hole 6,
And with primary blades 4 position one_to_one corresponding, in running produce part air quantity reach blower motor one by hollow hole 6
Side, beneficially motor radiating.
In addition, because of back blades 5 small volume, only help out, so only needing one end to be fixed on installation chassis 1
On, preferably one-body molded with installation chassis 1, it is also possible to be the alternate manners such as riveting.
