Description
Technical field
The present invention relates to wind turbine technical fields, and in particular to a kind of centrifugal blower.
Background technology
Centrifugal blower is to improve gas pressure by the mechanical energy of input and convey the machinery of gas, and centrifugal blower is used extensively
In the ventilation, dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, ship and building；Boiler and industrial furnace it is logical
Wind and air inducing；Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation；It the drying of cereal and selects and recommends；Worked
Cheng Zhong drives compressor impeller, air-flow, axially into blade space, to be acted in high-speed rotating impeller by wind turbine by common electric machine
Further aspect is rotated with impeller, on the other hand improves energy under the action of inertia, impeller is left along radial direction, by what is generated
Centrifugal force does work.
Traditional centrifugal blower is used in such a way that gear accelerates, it needs gear up transmission mechanism, conventional
Bearing
Support and oil lubrication system, this conventional centrifugal wind turbine the problem is that：On the one hand, due to using lubricating oil to machinery
Friction pair is lubricated, and is caused the air that wind turbine exports to carry oiliness, cannot be met the special industries such as food, medicine, electronics
Cleanliness without any pollution needs；On the other hand, since the power of common electric machine output needs to pass to by gear up transmission mechanism
Impeller, in power transmission process, the problems such as will produce great energy loss and noise because of mechanical friction, and speed increasing gear
The setting of case causes a whole set of Fan Equipment volume big, and occupied space is big.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of simple in structure, compact, volume
Small, easy to use and reliable, at low cost, wind-force is big, the low centrifugal fan of energy loss.
The purpose of the present invention is by following technical solution to complete, a kind of centrifugal blower, including：Engine base, spiral case, electricity
Machine and by the motor-driven impeller, the upper surface of engine base is equipped with a horizontal machine, and motor shaft stretches into from the axle center of spiral case
In the spiral case placed vertically, and the motor shaft ends in spiral case are equipped with the impeller axle bed with impeller；The spiral case
It is inside formed with circumferential circulation channel, the axial another side of the impeller axle bed is provided with horn-like air-vent.
As preferred：The engine base is desk-top engine base, the horizontal machine is equipped on upper transverse plane, side is fixed
The spiral case placed vertically is installed and three is integrally formed；The circulation channel outlet setting upward that is formed in the spiral case and
Outlet end is provided with connecting flange；The motor shaft of the horizontal machine and setting mechanical dynamic seal device at spiral case axle center.
The present invention is the improvement carried out in prior art basis, it has simple in structure, compact, small, user
It can lean on, at low cost, the features such as wind-force is big, and energy loss is low.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the A direction views of Fig. 1.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be described in detail：Fig. 1, shown in 2, a kind of centrifugation wind of the present invention
Machine, including：Engine base 1, spiral case 2, motor 3 and by the motor-driven impeller 4, the upper surface of engine base 1 is equipped with a horizontal machine
3, motor shaft 5 is stretched into from the axle center of spiral case 2 in the spiral case 2 placed vertically, and 5 end of the motor shaft installation in spiral case 2
There is the impeller axle bed 6 with impeller 4；Circumferential circulation channel 7 is formed in the spiral case 2, the axial direction of the impeller axle bed 6 is another
One end is provided with horn-like air-vent 8；Servo motor or variable-frequency motor may be used in the horizontal machine 5, so as to
In the direct impeller rotation of motor, rotating speed can be adjusted, and motor direct-connected can improve output power, improve work effect
Rate.
As shown in the figure, the engine base 1 is desk-top engine base, the horizontal machine 3 is equipped on upper transverse plane, side is solid
There is the spiral case placed vertically 2 in Dingan County and three is integrally formed；The outlet of circulation channel 79 formed in the spiral case 2 is set upward
It sets, and outlet end is provided with connecting flange 10；The motor shaft 5 of the horizontal machine 3 and setting machinery at 2 axle center of spiral case are dynamic
Sealing device 11.
