Abstract
The utility model discloses a centrifugal fan. The centrifugal fan comprises a motor base, a motor arranged at the upper end of the motor base and a casing arranged at the left end of the motor, wherein a rotating shaft of the motor is inserted into the right wall of the casing and connected with a wind wheel in the casing, an air inlet is formed in the right end of the casing, and an air outlet is formed in the lower end of the casing; and the wind wheel comprises a connecting ring and air pieces, the rotating shaft is sleeved with the connecting ring and the air pieces, the cross section of each air piece in the length direction is U-shaped, each air piece is arc-shaped in the length direction, one end of each air piece is fixed to the outer surface of the connecting ring, and the other end corresponds to the air outlet, and a flange is arranged at the air outlet. The cross section of each air piece in the length direction is U-shaped, the air pieces with the shape can guide air to be discharged from the air outlet, and noise generated by air discharged from the air outlet due to large air force is avoided; with the arrangement, different directions of the guided-in air can be guided in the same direction, so that the efficiency is improved, mounting and dismounting of the air outlet and an air outlet pipeline are facilitated, and the air outlet effect is good.
Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of centrifugal fan.
Background technique
Centrifugal blower be used for ventilation, dust discharge and cooling, relying on mechanical energy to improve supply gas the side by side machinery of body of gas pressure is a kind of machinery of driven fluid.
Current centrifugal blower comprises housing, is located at wind wheel and motor in housing, the rotating shaft of motor connects the wind wheel in housing, rotation by machine shaft drives wind wheel to rotate, wind wheel rotarily drives wind inlet place Air Flow, then from exhaust outlet, discharge, the cross section that this fan sheet is gone up mostly along its length is the rectangle of end band radian, the wind-force that the wind sheet of this shape drives is little, wind direction is mixed and disorderly, in many ways aweather easily cancel each other, weaken, produce noise, and the air output at exhaust outlet place is little, wind pipe and exhaust outlet installation and removal difficulty.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of air output large, the synchronous machine that noise is little.
To achieve these goals, the utility model is by the following technical solutions: a kind of centrifugal fan, comprise motor cabinet, be located at the motor of motor cabinet upper end, be located at the housing of motor left end, the right wall that housing is inserted in the rotating shaft of described motor is connected with the wind wheel in housing, the right-hand member of described housing is provided with intake grill, the lower end of housing is provided with exhaust outlet, described wind wheel comprises connecting ring and the wind sheet being sheathed in rotating shaft, described wind sheet cross section is along its length U-shaped, wind sheet is arc along its length, connecting ring outer surface is fixed in wind sheet one end, the corresponding exhaust outlet of the wind sheet the other end, described exhaust outlet place is provided with flanged disc.
As preferably, described connecting ring is provided with the prolonged section corresponding with wind sheet, on described wind sheet, has mounting hole, and screw is fixed on wind sheet on prolonged section through mounting hole.
As preferably, described wind sheet is made as 6, and prolonged section corresponding with wind sheet on described connecting ring is also made as 6.
In sum, the utlity model has following advantage: described wind sheet cross section is along its length U-shaped, the wind sheet of this shape can guide wind to discharge from exhaust outlet, and along with wind sheet leaves exhaust outlet, wind-force diminishes, and avoids the wind of not discharging from exhaust outlet because wind-force is excessive, to produce noise; Wind sheet is arranged to arc along its length, this arranges can be by the wind of the different direction of introducing, guide in the same direction, reduce the loss of wind-force, and then strengthened wind-force, and improved efficiency, described exhaust outlet place is provided with flanged disc, this is provided with the installation and removal that are beneficial to exhaust outlet and wind pipe, and air-out effect is good.
Accompanying drawing explanation
