Description
Technical field
The utility model relates to a kind of paddy process equipment, and especially a kind of paddy is produced and used low noise centrifugal blower.
Background technique
In paddy process line, need to use blower paddy is carried out to the processing such as rice bran separation.Existing blower exists static pressure little, and flow velocity is low, the problem that noise is large.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of paddy production and uses low noise centrifugal blower, can improve the deficiencies in the prior art, can improve static pressure and the flow velocity of blower, and reduces the noise producing due to fluid impact blower fan.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of paddy is produced and is used low noise centrifugal blower, structure comprises casing, bottom of shell is provided with motor, motor is connected with running shaft, on running shaft, be provided with two identical impellers, between the impeller near motor one side and motor, be provided with damping wheel, damping wheel is also arranged on running shaft, on the outside casing of the impeller near motor one side, be provided with annular air scoop, the width of annular air scoop is greater than the thickness of impeller, near the impeller of motor one side, be positioned at the center of annular air scoop, casing is provided with arc runner away from one end of motor, arc runner curves inwardly, arc runner is connected with exhaust outlet, the inner side of arc runner and exhaust outlet is provided with spirality guiding gutter.
As preferably, between described casing and arc runner, arc runner and exhaust outlet, be provided with Stamping Steel Ribbon.
As preferably, described casing, arc runner and exhaust outlet arranged outside have puigging.
The beneficial effect that adopts technique scheme to bring is: two impellers of the utility model design can reduce the impact force of air-flow to an independent impeller, and can be at static pressure and the flow velocity higher compared with acquisition under the slow-speed of revolution.Damping wheel be designed for the resonance producing while reducing vane rotary.Annular air scoop design, at the impeller location near motor one side, can strengthen air output to the full extent.Arc runner can effectively improve static pressure and the pressure of air-out, and spirality guiding gutter can reduce the phase mutual friction of air-flow and inwall, reduces noise.Stamping Steel Ribbon is used for reducing the leakage of air-flow, and can effectively prevent " blowing the trumpet " noise that high velocity air produces by gap.Puigging can carry out noise reduction process the noise producing.
