The utility model discloses a kind of monopole centrifugal blower, belong to blower technology field, its structure includes air inlet pipe, the spiral case and motor of built-in impeller, the gas outlet of air inlet pipe is connected with the air inlet of described spiral case, regulation door is installed between air inlet pipe and volute air-inlet mouth, the direction that the side of spiral case is vertical with air inlet is provided with gas outlet, the opposite side of air inlet is provided with high-speed gear box, the side of high-speed gear box is connected with the impeller axle in spiral case, the opposite side of high-speed gear box is connected with motor by shaft coupling, motor and spiral case are in frame.The utility model is compared with traditional screw rod blower fan, Multi-stage centrifugal fan, rotating speed is high, and air compression process shortens, and the time is short, air friction is little, cause compress temperature rise ratio conventional fan low more than 30 degree, impeller is little with spiral case gap, air leakage little, efficiency is high, separate unit runs, and is interacted when eliminating multiple stage parallel running between each, the shortcoming that wind-force is offset.
Description
Technical field
The utility model is related to blower technology field, specifically monopole centrifugal blower.
Background technology
At present, more than air blast using the traditional approach such as screw rod blower fan, Multi-stage centrifugal fan, traditional screw rod blower fan, multistage
In use, there is air compression temperature and lift high, air many, the big defect of energy consumption of leakage in centrifugal blower；Existing separate unit
Air blast is unable to reach use requirement, often by the way of multiple stage parallel running air blast, such that multiple stage air blast
Influence each other between machine, cause wind-force to offset, substantially increase energy consumption.
Content of the invention
Technical assignment of the present utility model is for above weak point, there is provided a kind of rational in infrastructure, rotating speed is high, efficiency is high
Monopole centrifugal blower.
The utility model solves the technical scheme adopted by its technical problem：The air blast includes air inlet pipe, built-in leaf
The spiral case and motor of wheel, the gas outlet of air inlet pipe are connected with the air inlet of described spiral case, air inlet pipe and volute air-inlet mouth it
Between regulation door is installed, the direction that the side of spiral case is vertical with air inlet is provided with gas outlet, sets with respect to the opposite side of air inlet
High-speed gear box is equipped with, the side of high-speed gear box is connected with the impeller axle in spiral case, the opposite side of high-speed gear box is by connection
Axle device is connected with motor, and motor and spiral case are in frame.
Filter is installed at the air inlet of described air inlet pipe.
Muffler is installed in air inlet pipe on rear side of described filter.
Fan shroud is installed on the outside of described spiral case, ripple is installed in fan shroud and the air inlet pipe of air inlet pipe connection
Line telescopic joint.
Monopole centrifugal blower of the present utility model compared with traditional screw rod blower fan, Multi-stage centrifugal fan, rotating speed
Height, air compression process shorten, and the time is short, and air friction is little, cause the temperature rise ratio conventional fan that compresses low more than 30 degree, leaf
Wheel is little with spiral case gap, and air is revealed little, and efficiency is high, separate unit operation, eliminates during multiple stage parallel running mutual shadow between each
Ring, the shortcoming that wind-force is offset is energy-efficient.

Device 7 is connected with motor 8, and motor 8 is in frame 11.
Above-mentioned filter 1 filters air plankton；Muffler 2 reduces noise；Bellow-type expansion joint 4 plays regulation installation effect,
Vibrations can also be reduced；Adjust door 9 and be also referred to as entry guide vane, adjust the anglec of rotation of stator, air-flow is produced before entering impeller and prewhirl, leaf
Wheel is rotated inside spiral case 5 at a high speed, and on high speed shaft, high speed shaft is connected impeller with high-speed gear box 6, and high gear is adopted
Helical gear, through Quenching Treatment, hardness is high, and machining accuracy reaches G1 levels for size gear surface.
By specific embodiment above, the those skilled in the art can readily realize the utility model.But
It is it should be appreciated that the utility model is not limited to above-mentioned several specific embodiments.On the basis of disclosed embodiment,
The those skilled in the art can be combined different technical characteristics, so as to realize different technical schemes.
