Cylinder and connection beam barrel, are provided with multiple bending blades, the connection beam barrel is centrally disposed between the outer barrel and connection beam barrel
It is useful for the axis hole with motor axis connection, the connecting cylinder side is provided with blowing mouth, a plurality of direction is additionally provided on connecting cylinder
The air blasting passage of multiple blades, the air blasting passage are connected to blowing mouth, and the multiple middle part of blade is offered for mitigating
The opening of leaf weight.
It is further：The suction inlet for being connect with extraneous dust exhaust apparatus, the suction inlet are provided on the outer barrel
Place is provided with the plug for blocking suction inlet.
It is further：The multiple blade is root of blade close to connection beam barrel side, and the root of blade is equipped with arc
Shape notch, the root of blade side are provided with arc panel, the shape size of the arc panel and the shape size of root of blade
It is identical.
It is further：The outer surface of the arc panel is coated with polytetrafluoroethylene ethylene layer.
It is further：The size of the opening is less than percent the 10 of leaf blade size.
The utility model has the beneficial effects that：Blowing mouth after use, need to only be connected extraneous blowing by this draught fan impeller
Device is blown away the dust on blade by the wind of external device from blade, so as to effectively be carried out to the dust on blade
Deashing processing, while the setting being open on blade can effectively reduce the weight of blade and reach to reduce the power of motor
Energy-efficient purpose.
Description of the drawings
Fig. 1 is impeller schematic diagram.
Fig. 2 is blade side view.
In figure label for：Outer barrel 1, connecting cylinder 2, blade 3, axis hole 4, blowing mouth 5, air blasting passage 6, opening 7, suction inlet 8,
Plug 9, arc panel 10.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
A kind of self-cleaning draught fan impeller as shown in Figure 1, including outer barrel 1 and connection beam barrel, the outer barrel 1 and connection beam barrel
Between be provided with multiple bending blades 3, the connection beam barrel is provided centrally with for the axis hole 4 with extraneous motor axis connection,
2 side of the connecting cylinder is provided with the blowing mouth 5 for being connect with extraneous blowing device, and a plurality of court is additionally provided on connecting cylinder 2
To the air blasting passage 6 of multiple blades 3, the air blasting passage 6 is connected to blowing mouth 5, and 3 middle part of the multiple blade opens up useful
In the opening 7 for mitigating 3 weight of blade, above-mentioned impeller gives an extraneous wind-force, such as after the completion of use at blowing mouth 5
The extraneous blowing device of installation one or to blowing etc. of using a fan at blowing mouth, wind blows to blade 3 by air blasting passage 6, by blade 3
On dust blow away, realize self-cleaning function, and the setting of opening 7 can effectively reduce the weight of blade 3 on blade 3,
Since 3 thickness of blade is unchanged, the intensity of blade 3 will not reduce, constant to may be implemented in original impeller function, intensity
In the case of reduce motor power, realize energy-efficient purpose.
On the basis of the above, as shown in Figure 1, being provided with the dust suction for being connect with extraneous dust exhaust apparatus on the outer barrel 1
Mouthfuls 8, the plug 9 being provided with for blocking suction inlet 8 at the suction inlet 8 pulls out plug 9 when during being cleaned
Going out, the sweep-up pipe of external dust catcher is inserted into suction inlet 8 so that the dust blown off on blade 3 can be siphoned away by dust catcher, from
And prevent dust from descending slowly and lightly into extraneous air and sucked by operating personnel, to cause damages to the body of operating personnel.
On the basis of the above, described as shown in Fig. 2, the close connection beam barrel side of the multiple blade 3 is 3 root of blade
3 root of blade is equipped with arc incision, and 3 root side of the blade is provided with arc panel 10, the shape size of the arc panel 10
Identical with the shape size of 3 root of blade, such setting can make blade 3 in rotation process, and arc panel 10 changes leaf
Flow field structure near 3 curved outer leading edge of piece, reduces dust particles and is adhered on blade 3, and subsequent cleaning is facilitated to grasp
Make.
On the basis of the above, the outer surface of the arc panel 10 is coated with polytetrafluoroethylene ethylene layer, and polytetrafluoroethylene (PTFE) is commonly referred to as
Make " non-sticking lining " or " material easy to clean ", the setting of polytetrafluoroethylene ethylene layer has been more convenient dust and has been blown off from blade 3.
On the basis of the above, the size of the opening 7 is less than percent the 10 of 3 size of blade, this impeller passes through opening 7
The restriction of size, to ensure that the intensity of blade 3 will not reduce.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, is not limited to this
