The utility model relates to centrifugation technique field, be specifically related to a kind of industrial centrifugal blower, be provided with flow-guide fan in air inlet, described flow-guide fan comprises several blades that the rotatingshaft with centrifugal blower rotates, and described blade is fin shape and blade rotation direction tilts 30 ~ 60 degree dorsad; Described flow-guide fan comprises the supporting element of the circle coaxial with the rotatingshaft of centrifugal blower, and described blade is located on supporting element; Blade is rearwardly tilted with curved line by root; The relative two edges that blade opens are arc; Blade lean direction is towards the inner side of centrifugal blower.The utility model can increase the air-flow of exhaust outlet, improves its water conservancy diversion speed, promotes working efficiency further.
Description
Technical field
The utility model relates to centrifugation technique field, particularly relates to a kind of industrial centrifugal blower.
Background technique
Centrifugal blower is equipment conventional in industry, and the general shape of its fan blade is similar to fan blade shape, and fan blade water conservancy diversion speed under fixing rotating speed of this structure is lower, inefficiency.
Model utility content
The utility model provides a kind of industrial centrifugal blower, and it can improve the water conservancy diversion speed of blade, improves the working efficiency of blower fan.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of industrial centrifugal blower, is provided with flow-guide fan in air inlet, and described flow-guide fan comprises several blades that the rotatingshaft with centrifugal blower rotates, and described blade is fin shape and blade rotation direction inclination 30 ~ 60 degree dorsad.
Being improved to further technique scheme, described flow-guide fan comprises the supporting element of the circle coaxial with the rotatingshaft of centrifugal blower, and described blade is located on supporting element.
Preferably, described blade pitch angle is 60 degree.
Preferably, described blade concrete structure is: blade is rearwardly tilted with curved line by root.
Preferably, the relative two edges that described blade is open are arc.
Preferably, described blade lean direction is towards the inner side of centrifugal blower.
Industrial centrifugal blower described in the utility model, beneficial effect is compared to existing technology:
A flow-guide fan is provided with in the air inlet of centrifugal blower, its blade shape is fin shape and blade rotation direction tilts 30 ~ 60 degree dorsad, the blade tilted when this structure makes centrifugal blower rotate can add the air-flow of exhaust outlet, improves its water conservancy diversion speed, promotes working efficiency further.
Accompanying drawing explanation
Accompanying drawing 1 is the flow-guide fan structural representation of the industrial centrifugal blower of the utility model embodiment;
Accompanying drawing 2 is the flow-guide fan partial structurtes schematic diagram of the industrial centrifugal blower of the utility model embodiment;
Accompanying drawing 3 is the industrial centrifugal fan structure schematic diagram of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment:
With reference to Fig. 3, industrial centrifugal blower described in the utility model, is provided with a flow-guide fan 1 in its air inlet.With reference to Fig. 1, several blades 21 that flow-guide fan 1 comprises circular supporting element 2 and is located on supporting element 2.Blade 21 is fixed on supporting element 2, rotates with supporting element 2.With reference to Fig. 2, blade 21 be fin shape, and blade 21 dorsad its sense of rotation tilts the angle of 30 ~ 60 degree, preferably 60 degree.The mode tilted tilts with the route of arc, instead of straight line tilts.The relative two edges (two edges that size is shorter) that blade 21 opens are arc, cushion air-flow.
With reference to Fig. 3, the true dip direction of this blade 21 is towards the inner side of centrifugal blower, and namely level and smooth outside centrifugal blower, blade 21 is positioned at inside centrifugal blower.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
