Abstract
The utility model discloses a fan wheel convenient to clearance dust, including rim plate and the blade of setting on the rim plate, the center department of rim plate is provided with the lug, the center department of lug is provided with the shaft hole that is used for installing the transmission shaft, be provided with a plurality of the corridors of blowing in the lug, the air outlet in corridor of blowing is located the side of lug, and the air intake in all corridors of blowing is same opening, and this opening is located the terminal surface of lug to external air -out device. Fan wheel use to accomplish after, with the external air -out device of air intake, wind blows away through the dust of corridor on with the impeller of blowing, can effectual clearance dust.
Description
Technical field
The utility model relates to a kind of draught fan impeller, is specifically related to a kind of draught fan impeller being convenient to clear up dust.
Background technique
In the production industry such as electric power, metallurgy, for discharging the centrifugal blower of flue gas, dust, often can accumulate dust in inner vanes or wheel disc, so that blower fan normally cannot work, what impact was produced normally carries out.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of draught fan impeller being convenient to clear up dust.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of draught fan impeller being convenient to cleaning dust, comprise wheel disc and be arranged on the blade on wheel disc, the center of described wheel disc is provided with projection, the center of described projection is provided with the axis hole installing transmission shaft, be provided with some blowing paths in described projection, the exhaust outlet in described blowing path is positioned at the side of projection, and the intake grill in all blowing paths is same opening, this opening is positioned on the end face of projection, and picks out wind apparatus.
Described draught fan impeller also comprises the dust shield be arranged on above impeller, the external vacuum cleaner of described dust shield.
Described dust shield is tubaeform dust shield or cylindrical dust shield.
Described projection is cylindrical bump.
Described blade is arc shaped blade.
Described blade is uniformly distributed.
The beneficial effect that the utility model reaches: after draught fan impeller described in the utility model is used to complete, intake grill is picked out wind apparatus, the dust on impeller is blown away by blowing path by wind; Effectively can clear up dust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As illustrated in fig. 1 and 2, a kind of draught fan impeller being convenient to cleaning dust, the blade 2 comprising wheel disc 1 and be arranged on wheel disc 1, blade 2 is arc shaped blade, blade 2 is uniformly distributed, the center of wheel disc 1 is provided with projection 4, projection 4 is cylindrical bump, the center of projection 4 is provided with the axis hole 3 installing transmission shaft, be provided with some blowing paths 6 in projection 4, the exhaust outlet 61 in blowing path 6 is positioned at the side of projection 4, and the intake grill in all blowing paths 6 is same opening 5, this opening 5 is positioned on the end face of projection 4, and picks out wind apparatus.
After above-mentioned draught fan impeller is used to complete, intake grill is picked out wind apparatus, the dust on impeller is blown away by blowing path by wind; Effectively can clear up dust.
In order to collect dust further, above-mentioned draught fan impeller also comprises the dust shield 7 be arranged on above impeller, the external vacuum cleaner of dust shield 7, and dust shield 7 is tubaeform dust shield or cylindrical dust shield.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
