Abstract
The utility model provides a centrifugal fan flow collector with an improved air inlet structure. The centrifugal fan flow collector with the improved air inlet structure comprises a flow collector body (10) and is characterized in that a support frame (20) in a shape like the Chinese character 'mi' is fixed to the inner sidewall of the flow collector body (10), wherein the support frame (20) is formed by a plurality of rods. A plurality of annular check rings (30) are fixed to the plane of one side of the support frame (20). According to the centrifugal fan flow collector with the improved air inlet structure, the support frame formed by the rods is fixed to the inner sidewall of the flow collector body, so steel plates with appropriate thickness are selected and made into the centrifugal fan flow collector, and the bearing strength of the centrifugal fan flow collector is guaranteed. Consequently, production intensity is reduced, and the curve radian of the inner sidewall of the centrifugal fan flow collector is guaranteed. Therefore, the centrifugal fan flow collector with the improved air inlet structure has a more lasting diversion effect.
Description
Technical field:
The utility model relates to the technical field of blower fan, more specifically to a kind of slip ring of air inlet of centrifugal fan architecture advances.
Background technique:
Slip ring, impeller, spiral case are the chief components that affects Aerodynamic Performance of Centrifugal Fan at present, and wherein slip ring is the important structure that guiding gas enters blower fan.And present slip ring is generally that steel plate processing is rolled to the tubaeform cylindrical shell forming, due to the flow guide device of slip ring as centrifugal blower, it need to bear larger blast, thereby causes the steel plate that forms slip ring need to have certain thickness.But the slip ring of manufacturing some large centrifugal fans requires the steel plate thickness of its formation thicker, has increased production and processing difficulty, has increased cost of production simultaneously.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of slip ring of air inlet of centrifugal fan architecture advances, it has guaranteed its bearing strength when selecting the steel plate of suitable thickness to form slip ring, effectively reduces difficulty of processing and cost of production.
Technology solution of the present utility model is as follows:
A slip ring for air inlet of centrifugal fan architecture advances, comprises the main body of slip ring, is fixed with ' rice ' font supporting frame that some ribs form on the madial wall of described main body, is fixed with some ring-type back-up rings on a side plane of supporting frame.
The main body of described slip ring is the bell mouth shape that air intake closes up gradually to outlet air end, and the air intake of main body forms ring-type flanging.
A described side plane that is fixed with the supporting frame of ring-type back-up ring approaches the air intake of main body, and the axle center of described some ring-type back-up rings is on same axis, and axle center is positioned at the center of supporting frame.
The beneficial effects of the utility model are:
1, it fixes a supporting frame being comprised of rib on the sidewall of slip ring body interior, steel plate that it selects suitable thickness is formed on the basis of slip ring and guaranteed its bearing strength, thereby reduced production intensity, also guaranteed the curve radian of slip ring madial wall, thereby there is more lasting water conservancy diversion effect simultaneously.
2, it is provided with from the ring-type back-up ring of supporting frame center diffusion on supporting frame, thereby plays the effect of protective net, can stop that foreign material enter blower fan inside, thereby avoid the damage of blower fan.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure: 10, main body; 11, air intake; 12, outlet air end; 13, ring-type flanging; 20, supporting frame; 30, ring-type back-up ring.
Embodiment:
Embodiment: see shown in Fig. 1,2, a kind of slip ring of air inlet of centrifugal fan architecture advances, the main body 10 that comprises slip ring, is fixed with ' rice ' font supporting frame 20 that some ribs form on the madial wall of described main body 10, be fixed with some ring-type back-up rings 30 on a side plane of supporting frame 20.
The main body 10 of described slip ring is the bell mouth shape that air intake 11 closes up gradually to outlet air end 12, and the air intake 11 of main body 10 forms ring-type flanging 13.
A described side plane that is fixed with the supporting frame 20 of ring-type back-up ring 30 approaches the air intake 11 of main body 10, and the axle center of described some ring-type back-up rings 30 is on same axis, and axle center is positioned at supporting frame 20 center.
Working principle: fixed the supporting frame 20 that supports pressure-bearing effect on the madial wall of slip ring, thereby increased the intensity that slip ring bears blast, ring-type back-up ring 30 is set on supporting frame 20 and can stops that foreign material enter blower fan inside, have avoided the damage of blower fan simultaneously.In March, 2012 < < refrigeration journal > > optimization research > > mono-literary composition of < < cabinet air-conditioner multi-wing centrifugal fan slip ring in use software FLUENT to analyze three kinds of different slip rings of structure, the slip ring of different structure is different to the guiding function of air-flow, and the air current flow form that causes entering after spiral case is also different.And air intake 11, the diameter of outlet air end 12 and the height of slip ring of two kinds of structures in three kinds of above-mentioned structures are all identical, radian difference that just it closes up to outlet air end 12 gradually from air intake 11, but its guiding effect to air-flow has larger difference.Current existing slip ring closing in radian designs through long time test, it has stronger water conservancy diversion efficiency, but its long-term wind-engaging impacts, its closing in radian can deform, thereby affect its water conservancy diversion effect, the utility model arranges a supporting frame 20 on the radian face of slip ring, can effectively reduce the distortion of its radian, thereby has more lasting water conservancy diversion effect.
