Abstract
The present invention relates to a stepped wheel of an airflow crusher, which comprises a front flange disk, a back flange disk, a plurality of blades and an air sealing disk, wherein the blades are respectively and fixedly connected with the front flange disk and the back flange disk, an annular groove is arranged on the air sealing disk, and the back end parts of the blades are inserted in the annular groove; a feed crack is arranged between the adjacent blades, and the inner sides of the blades form a cavity; the back end parts of the blades are provided with blade tail parts which are enlarged in a radial direction, and the rotary linear velocity of the blade tail parts is higher than that of the blade part on the front part; the airflow formed on the blade tail parts because of rotation can stop powder outside the blade tail parts, and the material powder which is selected by rotating the blades enters a material discharging pipe from the feed crack.
Description
Technical field
The present invention relates to a kind of grading wheel of airslide disintegrating mill.
Background technology
In the prior art, the grading wheel of airslide disintegrating mill comprises the forward flange dish, rear stub, be fixedly connected on the blade between forward flange dish and the rear stub, gas sealing disk, wherein, have cannelure on the gas sealing disk, the end of rear stub then is inserted in the cannelure, the forward flange dish can be enclosed within on the power transmission shaft to rotate under the drive of power transmission shaft, and drive blade rotation, smalls after material is pulverized enters the back by the slit between the blade and is discharged by the cavity of blade inboard, but owing to have the gap between the wall portion of blade and cannelure to guarantee the normal rotation of blade, so powder easily enters in the gap between blade and the annular groove wall portion when the running of this grading wheel, directly from cavity, discharge without the slit between the blade, influenced the grading effect of this grading wheel.
Summary of the invention
The object of the invention provides a kind of grading wheel of airslide disintegrating mill, and the material smalls can only enter cavity from the seam of the charging between the blade.
For achieving the above object, the technical solution used in the present invention is: the grading wheel of airslide disintegrating mill, comprise the forward flange dish of coaxial setting and rear stub, along a plurality of blades, the gas sealing disk that distribute with the coaxial circumferencial direction of described forward flange dish, the front portion of described blade and forward flange dish are fixedly connected, the rear portion of described blade and described rear stub are fixedly connected, along the circumferential direction have cannelure on the described gas sealing disk, the rearward end of described blade is inserted in the cannelure.Have the charging seam between the described adjacent vanes, the inboard of described a plurality of blades forms cavity, and described charging seam is connected with cavity, and the rearward end of described each blade has the blade afterbody that radially becomes big.
Because technique scheme utilization, the present invention compared with prior art has following advantage: the rearward end of blade has the radially blade afterbody of projection, when blade rotates, the rotational line speed of blade afterbody is higher than the rotational line speed of the blade-section of its front side, so the air-flow that the rotation of blade afterbody forms can prevent the powder greater than setting value and enter in the gap between blade afterbody and the annular groove wall, powder after making material pulverize must enter cavity through blade rotation selection and from the charging seam, and control the particles of powder size that enters charging seam, thereby guaranteed the grading effect of this grading wheel by the adjusting vane rotating speed.

The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 3, a kind of grading wheel of airslide disintegrating mill, comprise the forward flange dish 1 of coaxial setting and rear stub 3, along a plurality of blades 2, the gas sealing disk 4 that distribute with the coaxial circumferencial direction of described forward flange dish 1, the front portion of described blade 2 and forward flange dish 1 are fixedly connected, the rear portion of described blade 2 and described rear stub 3 are fixedly connected, along the circumferential direction have cannelure 9 on the described gas sealing disk 4, the rearward end of described blade 2 is inserted in the cannelure 9.Have charging seam 6 between the described adjacent vanes 2, the inboard of described a plurality of blades 2 forms cavity 8, and described charging seam 6 is connected with cavity 8.The axial line place of forward flange dish 1 has the installing hole 7 of taper, in this installing hole 7 power transmission shaft can be installed, under the drive of power transmission shaft, forward flange dish 1 drives blade 2, rear stub 3 rotations, the less powder of particle that material forms after airslide disintegrating mill is pulverized can enter in the charging seam 6, and the size that enters the powder in the charging seam 6 by the controllable rotation speed system of adjusting vane 2.
Referring to accompanying drawing 2, the rearward end of described each blade 2 has the blade afterbody 5 that radially becomes big, and described blade afterbody 5 is positioned at the rear side of rear stub 3.When blade 2 rotations, because the radius of blade afterbody 5 is greater than the radius of the blade 2 of its front side, so the linear velocity of the outer rim of blade afterbody 5 rotation is bigger, outside the air-flow that its rotation forms can be blocked in powder, can prevent that powder from being entered in the cavity 8 by the gap between blade afterbody 5 and cannelure 9 walls.And be to guarantee that the air-flow that 5 rotations of blade afterbody form exerts an influence to powder, the outward flange of described blade afterbody 5 is convex external peripheral surface for rear stub 3 in the footpath of rear stub 3.Because the radius of blade afterbody 5 is greater than the radius of rear stub 3, making has two kinds of linear velocities at same grading wheel cylindrical, be the rotational line speed of the linear velocity of blade afterbody 5 rotations greater than rear stub 3, thereby the air-flow that makes 5 rotations of blade afterbody produce directly exerts an influence to the powder in blade afterbody 5 outsides, gap between the wall portion of blade afterbody 5 and cannelure 9 is closed substantially and prevents that powder from passing through, and has improved the grading effect of grading wheel greatly.
