Specific implementation mode
The utility model is described in detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 3, the purpose of the present embodiment is that proposing a kind of large flow single-stage cantilever SO2Centrifugal blower, including leaf
Wheel 1 and the blade 2 being arranged on impeller 1.Wherein, impeller 1 is the efficient impeller of big flow coefficient.Blade 2 is semi-open type three
First backward leaning vane.Between impeller 1 and the volute structure of centrifugal blower, a kind of funnelform medium channel can be formed, therefore
Centrifugal blower has higher efficiency.Can be able to be that aforementioned funnelform medium is logical using semi-open type ternary backward leaning vane
The radial position in road, which is formed, is similar to closed effect.This effect for being similar to sealing can prevent medium from medium channel
Radial position is overflowed, to improve centrifugal blower efficiency.Large flow single-stage cantilever SO2Centrifugal blower, relative to existing
Single-stage cantilever SO in technology2Centrifugal blower, have the characteristics that flow is big, safe and stable, efficient.
Preferably, for SO2Impeller 1 and blade 2 are all made of FV52B high-strength stainless steels and are made by medium.FV52B high
Intensity stainless steel has excellent corrosion-resistant characteristic, is suitable for SO2For the centrifugal blower of medium.
As shown in Figure 1 and Figure 2, further, in order to more preferably promote the service efficiency of centrifugal blower, centrifugal blower
Entry guide vane device 3 is set before inlet end.The SO entered in centrifugal blower is adjusted by entry guide vane device 32Flow, to
The wide range of properties for realizing centrifugal blower is adjusted, the enhancing of centrifugal blower practicability.Not only improve making for enterprise customer
With efficiency, the type selecting of enterprise customer and the research and development manufacture of enterprise easy to produce are also allowed for.3 axial line water of entry guide vane device
The axial line of flat setting, spiral case 4 is horizontally disposed, and entry guide vane device 3 is coaxially connected by bolt with spiral case 4.In use, centrifugation
Air blower is by axial admission, i.e., from the axial sucking SO of entry guide vane device 32；Centrifugal blower is from radial exhaust, i.e., from spiral case
4 it is radial by SO2Discharge.
As shown in Figure 1 and Figure 2, further, in order to promote the mechanical efficiency of centrifugal blower, diffusion is added in spiral case 4
Device 5.Pass through diffuser 5 so that the SO of centrifugal blower discharge2Pressure increases, therefore increases mechanical efficiency.Diffuser 5 is logical
The mode for crossing screw or clamping is connect with spiral case 4.Diffuser 5 is arranged in the rear end of 2 exhaust end of blade.SO2It is discharged from blade 2
Afterwards, it is discharged using diffuser 5.
As shown in Figure 1 and Figure 2, further, in order to promote the mechanical efficiency of centrifugal blower, type ring is added in spiral case 4
6.By the way that type ring 6 is arranged so that the smaller gap with near-hermetic between blade 2 and spiral case 4, to improve impeller 1
And its mechanical efficiency of blade 2.Type ring 6, which is arranged, to be arranged in the inlet end side of blade 1.Pass through type ring 6, impeller 1 and its leaf
Space made of piece 2 surrounds forms a funnelform channel.SO2Enter from funnelform channel, from the exhaust of blade 2
End discharge.In addition, the hardness of type ring 6 is less than the hardness of blade 2.The centrifugal blower with the type ring 6 is used for a long time, can subtract
The abrasion of few blade 2.After long-time service, type ring 6 has certain abrasion, to reduce the sealing between type ring 6 and blade 2
Efficiency.Therefore, the sealing effect between type ring 6 and blade 2 can be kept by replacing type ring 6.
As shown in FIG. 1 to 3, further, in order to promote the mechanical efficiency of centrifugal blower, in 1 axial admission of impeller
End setting kuppe 7.Kuppe 7 can disperse the SO being inhaled into2, the pressure of impeller 1 and blade 2 is balanced, SO is reduced2Pressure
Unbalanced acting effect, improves mechanical efficiency.The inlet end front end on the axial line of impeller 1 is arranged in kuppe 7.It uses
When, SO2After being inhaled into spiral case 4, by the effect of kuppe 7, the expansion spread around centered on kuppe 7 is generated
Pressure, using expansion pressure so that SO2It uniformly enters between blade 2.
As shown in Figure 1, further, centrifugal blower further includes gear-box.Between centrifugal blower and gear-box and tooth
Roller box ontology, which is respectively provided with, can prevent SO2The sealing structure of leakage.Due to SO2Chemical characteristic, so it has to be ensured that centrifugation drum
The sealing safety of fan body and its gear-box, meanwhile, it is contemplated that under conditions of centrifugal blower is used for a long time, sealing knot
The reliability of structure.Such as the factors such as abrasion, heated are required to take into account.The present embodiment provides two preferred sealing structures,
When inflatable labyrinth seal structure, second is that inflatable carbon ring sealing structure.Both sealing structures can be safe for a long time
It is reliable to use, the centrifugal blower proposed suitable for the present embodiment.
Centrifugal blower further includes casing 8, and casing 8 is made of carbon steel.For the ease of the assembling of centrifugal blower, preferably
, casing 8 is set to vertical subdivision structure, by being welded to connect.Simultaneously, it is contemplated that SO2Chemical characteristic, and its condensation
SO2Influence of the solution to centrifugal blower, in the bottom of casing 8, setting has the tap that can discharge waste liquid and/or waste residue.
Centrifugal blower further includes speed reducer and driving motor.Centrifugal blower, speed reducer and driving motor include sliding
Dynamic bearing, and share a lube plant lubrication.By the way that a lubricating arrangement is arranged, for centrifugal blower lubrication in need
Component be lubricated.Relative to one-to-one lubricating system, a lubricating arrangement can save material, structure space, to
Cost can be reduced.In addition, using sliding bearing, lubricating oil forced feed lubrication preferably is configured simultaneously, enables to sliding bearing
High efficiency, stabilization, the good operation of heat dissipation.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
