Abstract
The utility model provides a double-layered fan impeller with a reasonable structure and high integral strength. The double-layered fan impeller comprises a hub and a plurality of inner blades located on the outer periphery of the hub, rings are sleeved on the outer peripheries of the inner blades, and a plurality of outer blades are arranged on the outer peripheries of the rings. The rings are sleeved on the outer peripheries of the inner blades, so that the ends of the inner blades are mutually connected, the strength of the inner blades is increased, furthermore, the outer blades are arranged on the outer peripheries of the rings, the length of each outer blade is only a half of that of a blade of a traditional fan impeller under the condition that the outer diameter of each outer blade is equal to that of the blade of the traditional fan impeller, and accordingly stability of the double-layered fan impeller is better.
Description
Technical field
The utility model relates to a kind of fan, is specifically related to a kind of double-deck blast fan that is applied on the fan.
Background technique
Blast fan commonly used in our daily life generally is made up of wheel hub, a plurality of blade that is positioned on the wheel hub excircle, and the blade of fan is big more usually, and its wind speed is big more, yet blade is big more, and the intensity of its blade is just low more.When the insufficient strength of blade, when the outer end is unstable, can produce more serious vortex phenomenon, influence the working life of whole impeller.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of rational in infrastructure, layer blast fan that the impeller bulk strength is high.
The utility model solves the technological scheme that its technical problem adopted:
A kind of double-deck blast fan comprises wheel hub and a plurality of intra vanes that are positioned at the wheel hub excircle, is socketed with annulus on the excircle of said a plurality of intra vanes, and the excircle of annulus is provided with a plurality of outer leafs.
In the utility model, said intra vane is evenly distributed on the wheel hub excircle.
In the utility model, said outer leafs is evenly distributed on annulus.
In the utility model, said intra vane, outer leafs are installed respectively on the excircle of wheel hub and annulus obliquely, and intra vane is consistent with the direction that outer leafs tilts.
In the utility model, the number of said outer leafs is more than the number of intra vane.
The beneficial effect of the utility model is: the utility model is socketed with annulus on the excircle of intra vane, and the end of a plurality of intra vanes is connected with each other, and strengthens the intensity of intra vane; Further; On the excircle of annulus, be provided with a plurality of outer leafs, compare, under the equal situation of external diameter with the conventional fan impeller; The length of outer leafs has only the half the of conventional fan impeller blade length, so its stability is better.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is further specified:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2; The layer blast fan that present embodiment provided was a kind of rational in infrastructure, the impeller bulk strength is high; Comprise wheel hub 1 and a plurality of intra vanes 2 that are positioned at wheel hub 1 excircle; In the present embodiment, totally five intra vanes 2 are evenly distributed on wheel hub 1 excircle, and intra vane 2 favours the cross section of wheel hub 1.Be socketed with annulus 3 on the excircle of said five intra vanes 2, the excircle of annulus 3 is provided with a plurality of outer leafs 4.In the present embodiment, 12 outer leafs 4 are evenly distributed on the annulus 3, and outer leafs 4 favours the cross section of annulus 3, and outer leafs 4 is all consistent with the square and angle that intra vane 2 tilts, and is consistent to guarantee flowing to of its air.
Further, because the diameter of annulus 3 is greater than the diameter of wheel hub 1, for reasonably using annulus 3 spaces, generally speaking, the number of said outer leafs 4 is more than the number of intra vane 2.
The above is merely the preferential mode of execution of the utility model, as long as realize that with basic identical means the technological scheme of the utility model purpose all belongs within the protection domain of the utility model.
