Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of material handling fan.
Background technique
Material handling fan comprises centrifugal impeller and casing now, impeller is positioned at the inner chamber of casing, casing is provided with intake grill and exhaust outlet, and intake grill center line and impeller center line coincide, and exhaust outlet is positioned at the tangent direction of impeller, though this material handling fan is simple in structure, but the material of carrying need pass through the inner chamber and the exhaust outlet of intake grill, casing, during material process wind conveyer, the impeller of material and chassis cavity is bumped, cause the breakage of material and the working life of reducing impeller.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and can not damage material, improve the impeller material handling fan in working life.
The technological scheme that the utility model solves the problems of the technologies described above is:
A kind of material handling fan, comprise casing, impeller, casing surrounds chassis cavity, casing is provided with intake grill and exhaust outlet, and described impeller is positioned at the impeller cavity of casing back side panel one side, and impeller cavity communicates with chassis cavity, described impeller is made up of axial blade and centrifugal impeller, centrifugal impeller comprises centrifugal blade, hub discs, front shroud and wheel plate, and centrifugal blade is fixed between front shroud and the wheel plate, and axial blade is fixed on the outside of front shroud.
As improvement, the center of impeller and the center of material feeding mouth are not point-blank.
As improvement, hub discs is connected by spoke with the wheel plate.
Technique effect of the present utility model is: because the utility model impeller is positioned at the impeller cavity of casing back side panel one side, impeller cavity communicates with chassis cavity, the air suction that material produces by the axial blade rotation, enter chassis cavity by intake grill, under the air centrifugal action that the centrifugal blade rotation produces, material is thrown out of through exhaust outlet then, and material no longer bumps with impeller, thereby make the utility model impeller can not damage material, improved impeller working life.The axle center of impeller and the axle center of material feeding mouth not point-blank, purpose is further to reduce the chance that material and impeller bump, and especially reduces the chance that material enters hub discs, improves the reliability of blower fan.Space between the adjacent spokes helps the air flows in the impeller cavity, reduces the resonance phenomenon of impeller.

Embodiment
Describe in detail below by drawings and Examples:
As shown in Figure 1 to Figure 3, a kind of material handling fan comprises casing 1, impeller 3, motor 4, casing 1 surrounds chassis cavity 5, casing 1 is provided with intake grill 10 and exhaust outlet 11, and described impeller 3 is positioned at the impeller cavity 2 of casing back side panel one side, and impeller cavity 2 communicates with chassis cavity 5.
Extremely shown in Figure 6 as Fig. 4, described impeller 3 is made up of axial blade 8 and centrifugal impeller, centrifugal impeller comprises centrifugal blade 7, spoke 9, hub discs 13, front shroud 12 and wheel plate 6, axial blade 8 is fixed on the outside of front shroud 12, hub discs 13 is connected by spoke 9 with wheel plate 6, space between the adjacent spokes 9 helps the air flows in the impeller cavity 2, reduces the resonance phenomenon of impeller 3.The center of the center of impeller 3 and intake grill 10 further reduces the chance that material and impeller bump not point-blank, especially reduces the chance that material enters hub discs, improves the reliability of blower fan.Fig. 5 arrow is represented the use sense of rotation of impeller 3.
The unspecified content of the utility model is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
