Description
Technical field
It the utility model is related to industrial production technology field, more particularly to a kind of Ai Fei acid and alkali-resistances blower fan.
Background technology
Blower fan is that China includes to the custom of gas compression and gas conveying machinery abbreviation, usually said blower fan：Ventilation
Machine, air blower, wind-driven generator.Gas compression and gas conveying machinery be the mechanical energy of rotation be converted to gas pressure can and
Kinetic energy, and the machinery that gas is transferred out.The main structural components of blower fan are impeller, casing, air inlet, support, motor, skin
Belt wheel, shaft coupling, muffler, driving member (bearing) etc..
Existing blower fan sometimes can not only convey air, can also convey some industrial waste gas, and in these waste gas
Regular to occur that band is corrosive the gas of function, when conveying these gases, the time has been grown to cause present blower fan
Internal flabellum and bearing is corroded, and the machinery after being corroded then is likely to result in unexpected generation at work.
Utility model content
The purpose of this utility model is and a kind of Ai Fei acid and alkali-resistances proposed in order to solve shortcoming present in prior art
Blower fan.
To achieve these goals, the utility model employs following technical scheme：A kind of Ai Fei acid and alkali-resistances blower fan, including
Blower fan, the blower fan side is welded with blast pipe, and blower fan opposite side is welded with discharge pipe, is offered out inside the discharge pipe
Air port, the blower interior are provided with sealed bearing, and sealed bearing surface soldered has a flabellum, in the sealed bearing
Portion is provided with centre bearing, and the blower fan surface is fixed with anticorrosion shell, and the blower fan side is fixed with motor, and motor surface
Offer radiator window.
As further describing for above-mentioned technical proposal：
The radiator window is provided with multiple altogether, and multiple radiator windows are evenly distributed on motor surface.
As further describing for above-mentioned technical proposal：
The flabellum is provided with multiple altogether, and is fixedly welded with protective case between multiple flabellums.
As further describing for above-mentioned technical proposal：
The motor is electrically connected with centre bearing.
As further describing for above-mentioned technical proposal：
The anticorrosion shell is the external FRP integrated casings for being socketed in blower fan surface.
In the utility model, and existing blower fan is compared, and this Ai Fei acid and alkali-resistance blower fan has energy-efficient
Feature is closed design bearing, can prevent Acid-base Gas from invading, and avoids bearing, axle center from directly being corroded by etchant gas, it is ensured that
Operate the life-span of middle (center) bearing.Blower housing material is for glass fiber reinforced plastics and using making is integrally formed, to avoid producing
Stress simultaneously increases intensity.Shell should be shiny surface design to avoid debris from adhering to.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of Ai Fei acid and alkali-resistances blower fan, including blower fan 1, it is characterised in that the side of blower fan 1 is welded with air intake
Pipe 11, and the opposite side of blower fan 1 is welded with discharge pipe 12, air outlet 13 is offered inside discharge pipe 12, blower interior is provided with close
Envelope formula bearing 3, and the surface soldered of sealed bearing 3 has flabellum 31, sealed bearing 3 is internally provided with centre bearing 33, blower fan 1
Surface is fixed with anticorrosion shell 2, and the side of blower fan 1 is fixed with motor 14, and the surface of motor 14 offers radiator window 15.
Radiator window 15 is provided with multiple altogether, and multiple radiator windows 15 are evenly distributed on the surface of motor 14.
Flabellum 31 is provided with multiple altogether, and protective case 32 is fixedly welded between multiple flabellums 31.
Motor 14 is electrically connected with centre bearing 33.
Anticorrosion shell 2 is the external FRP integrated casings for being socketed in the surface of blower fan 1.
