The second, materials flow is the material distributing cone of center of impact at first, and material distributing cone has tapering, be intended to allow material reflect feed cavity, but along with the increase of wearing and tearing, tapering has become scraggly hole, will expect irregular reference on the contrary, makes impeller work not steady more.
The 3rd, before the impeller sub-material chamber, the class triangle zone between material casting head and the counterattack piece rotates the wind of agitating at a high speed, is catabiotic, materials flow is no advantage, and be the main source of invalid windage.
Because above-mentioned 3 points, the power consumption of system sand machine ubiquity is huge, and impeller work is not steady, the consumable accessory rapid wear, and also production capacity and power consumption do not match.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of super-flow efficient stream line style system sand machine impeller, changes the shape of material distributing cone and runner section, is designed to shoulder groove structure, and flow is 2-3 a times of impeller in the past, and efficient energy-saving is durable in use.
The utility model is to realize by following technical scheme:
A kind of super-flow efficient stream line style system sand machine impeller comprises circular impeller body, in described impeller body center material distributing cone is set, and described material distributing cone is around the staged runner, and described each rank water passage surface is provided with hopper.
Described impeller body inside is provided with the power flabellum, and described power flabellum is the streamline-shaped with radian.The radian of its shape has certain cushioning effect when making it rush at materials flow at a high speed when work.In R﹠D process of the present utility model, the tangential direction that this power flabellum is streamlined goes up arbitrarily any and the angle of the acceleration direction of this point are controlled at a zone of reasonableness when interior, flow backwards phenomenon and turbulent phenomenon can not occur.
Described impeller body outer surface is provided with the counterattack deep bead.Deep bead can stop the generation in invalid windage district, and invalid windage district is that the setting by the counterattack deep bead stops its formation by the area of material casting head material of dishing out and the class trigonum of strikeing back the device composition.
The beneficial effects of the utility model are: solved the machinery dynamical balancing in the impeller high speed rotating, the wear-resisting and power saving of the handling problem of super-flow and equipment; The utility model can be by the material (per hour 600 tons) of super-flow, be existing impeller 2-3 doubly, have high treatment effeciency.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1-1,1-2 and Fig. 2-1,2-1, before the work beginning, no matter be the turbine of three blow tanks or the turbine of four blow tanks, static balance is proofreaied and correct in the capital, but because material distributing cone 101 trapezoidal and be similar to the design of centrum, make the materials flow straight line shock of the charging aperture at its top, damage material distributing cone 101 surfaces; After impeller startup work, as structural design among the figure, foregoing refluence district, turbulent region and invalid windage district (the class trigonum of forming between material casting 102 and the counterattack piece 103 among the figure) also can appear, and make the power consumption of system sand machine huge, impeller job insecurity, wheel member also damage easily.
As Fig. 3-1,3-2, be respectively the profile and the vertical view of the front view of impeller of the present utility model, comprise circular impeller body 3, material distributing cone 301 is set in impeller body 3 centers, described material distributing cone is around staged runner 302, and each rank runner 302 surface is provided with hopper 303.When material distributing cone 301 is impacted in materials flow; some material is introduced into and serves as the material lining in the hopper 303; play the effect of shock absorbing protection material distributing cone 301; after hopper 303 has been expired; material substantially radially flows under action of centrifugal force in second material lining groove; and continue successively downwards, material progressively is accelerated, until the impeller outer of being dished out.This structure had both been avoided the impact of supplied materials, had alleviated the friction of materials flow to runner plate again.Initial estimate, new runner plate should be three times of life-spans of former runner plate.
Impeller body 3 inside are provided with power flabellum 304, and power flabellum 304 is the streamline-shaped with radian.The radian of its shape has certain cushioning effect when making it rush at materials flow at a high speed when work.
