Description
Technical field
The utility model is related to Fan Equipment technical field, and in particular to a kind of axial fan abrasion-resistant blade.
Background technology
Axial fan, purposes is exactly the equidirectional air-flow of axle with fan blade, such as electric fan, outdoor machine of air-conditioner widely
Fan is exactly that axle stream mode runs blower fan, why is referred to as " axial-flow type ", is the axial-flow type because gas flows parallel to fan shaft
Blower fan is generally used for the occasion that traffic requirement is higher and pressure requirements are relatively low；Many large fans are applied to coal yard or steel at present
Factory, for carrying out air draft blowdown to production on-site, after long-time use, can form very thick schmutzband in blower fan inwall, because
And blower fan remains in operation and very big infringement can be caused to fan blade, and blade is overall construction, is damaged if any a bit, just
All to be changed, very big waste can be caused.
Utility model content
The purpose of this utility model provides a kind of axial fan abrasion-resistant blade, solves one in above-mentioned prior art problem
It is individual or multiple.
According to a kind of axial fan abrasion-resistant blade of the present utility model, including the impeller being connected with motor, the impeller
Blade including center drum and on the cylinder, the blade tip is provided with wear-resistant block, and the wear-resistant block includes first
Fixed block and the second fixed block, first fixed block are fixed on the blade tip, and second fixed block passes through fixed spiral shell
Tether and connect first fixed block.
A kind of axial fan abrasion-resistant blade provided by the utility model, it is simple in construction, it is practical, when the leaf of blower fan
When piece end sustains damage, just only need to change wear-resistant block, it is cheap without changing whole impeller, save a large amount of
Financial resources, increase operating efficiency.
In some embodiments, the hardness of first fixed block is more than the hardness of second fixed block.Second consolidates
Determine after block abrasion, influence whether the first fixed block, the first fixed block is better than the second fixed block, blade can be prevented to be damaged.
In some embodiments, second fixed block is L-shaped, and first fixed block is provided with neck, described
Second fixed block short end inlay card enters in the neck.It is simple in construction, convenient maintenance and replacement.
Brief description of the drawings
Fig. 1 is a kind of a kind of structural representation of axial fan abrasion-resistant blade 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, a kind of axial fan abrasion-resistant blade, including the impeller 1 being connected with motor, during impeller 1 includes
Heart cylinder 11 and the blade 12 in the surrounding of cylinder 11 is fixedly installed in by welding manner, blade 12 is set in certain angle of inclination
Put, and blade 12 is towards consistent, the end of blade 12 is installed with wear-resistant block 13, and wear-resistant block 13 is used to protect blade 12 to be damaged,
Wear-resistant block 13 includes the first fixed block 131 and the second fixed block 132, and the first fixed block 131 is fixed on blade by welding manner
12 ends, the second fixed block 132 by fixing bolt 133 connect the first fixed block 131, wherein, the first fixed block 131 it is hard
Degree after the second fixed block 132 weares and teares, can then may wear to the first fixed block 131 more than the hardness of the second fixed block 132, because
And, the first fixed block 131 is better than the second fixed block 132, and blade 12 can be prevented to be damaged.
Cylinder 11, impeller 1 and wear-resistant block 13 mentioned in above-mentioned are made of metal material.
Neck 134 is offered on first fixed block 131, the second fixed block 132 is L-shaped, including a long end and short end
Portion, is fixedly connected between long end and short end portion by welding manner, and short end portion matching inlay card enters in neck 134, and leads to
Cross fixing bolt 133 and be fixedly connected at installation, the nut of fixing bolt 133 and carry out plastic packaging with wax.
When blower fan inwall is residual dirt, the wear-resistant block 13 on blade 12 can be worn and torn, thus the second fixed block 132
Damage is had, is periodically checked, such as finds that the second fixed block 132 has abrasion, then plastic packaging is removed, unload fixing bolt 133,
More preferable second fixed block 132.
A kind of axial fan abrasion-resistant blade provided by the utility model, it is simple in construction, it is practical, when the leaf of blower fan
When piece end sustains damage, just only need to change wear-resistant block, it is cheap without changing whole impeller, save a large amount of
Financial resources, increase operating efficiency.
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.
