Abstract
The invention discloses a kind of jet mill high-effective classifying impeller blade structure, including the front impeller disk, the rear impeller disk and some blades, described blade is fixedly connected between the forward and backward impeller disk and forms a circle, there is between adjacent blades charging seam, the inner side of one circle blade forms cavity, each described blade is all made up of a primary blades and at least one auxiliary blade, described auxiliary blade be fixedly connected on described primary blades and and described primary blades between there is angle, therefore, it is possible to effectively reduce eddy current, the reduction windage that blade produces, and then improve yield and effectiveness of classification.
Description
Technical field
The present invention relates to the grading wheel of a kind of jet mill, be specifically related to a kind of blade construction that improves
Grading wheel.
Background technology
It is all by compressed air is spurted into pulverizing cavity through nozzle at high speeds during jet mill work,
At the joint of multiply high pressure draught material by impact several times, rub, shear and pulverize, powder
Material after broken moves to graded region with ascending air, at high speed rotating under blower fan draft effect
Grading wheel produce powerful centrifugal action under, make thickness feed separation, meet granularity requirements
Fine grained by grading wheel discharging, coarse granule drops to disintegrating area to be continued to pulverize.Wherein, divide
During step cone work, under the influence of centrifugal force, big or weight granule centrifugalization power is big for gas powder
, therefore got rid of to grading wheel peripheral to graded region limit wall, and no longer affected by centrifugal force, natural
Continue to pulverize in dropping to pulverizer；Little or light material is little by centrifugal action, enters with air-flow
Enter grading wheel, flow to next unit along pipeline.Just may be used by the rotating speed of regulation grading wheel
When adjusting gradation, the size of centrifugal force, reaches to separate the purpose of the material of designated size.
In prior art, the structure of grading wheel as it is shown in figure 1, include the front impeller disk 1, the rear impeller disk 2 with
And the circle blade 4 being fixedly connected between the forward and backward impeller disk.Have between adjacent blade into
Material seam, the inner side of multiple blades forms cavity.Such as figure
Shown in 2, traditional blade is straight plate type vane, and the assembling side that employing blade is perpendicular with wheel hub
Formula, there is following defect in this blade construction: when grading wheel rotates, and blade can produce local
Eddy current, this eddy current can increase gas-flow resistance, thus can affect classification efficiency.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of jet mill high-effective classifying impeller blade knot
Structure, the jet mill high-effective classifying impeller blade structure of the present invention can effectively eliminate eddy current, fall
Low windage, reduces energy consumption, improves classification efficiency, again and simple in construction, easy to implement.
The present invention is to solve that its technical problem be the technical scheme is that
A kind of jet mill high-effective classifying impeller blade structure, if including the front impeller disk, the rear impeller disk and
Cured leaf sheet, described blade is fixedly connected between the forward and backward impeller disk and forms a circle, adjacent leaf
Having charging seam between sheet, the inner side of a circle blade forms cavity, and each described blade is all by one
Individual primary blades and at least one auxiliary blade are constituted, and described auxiliary blade is fixedly connected on described primary blades
And and described primary blades between there is angle.
The present invention is to solve that the further technical scheme that its technical problem is used is:
It is preferred that each blade is all made up of a primary blades and an auxiliary blade.
Described primary blades is straight plate type vane.
It is preferred that the described front impeller disk and the described rear impeller disk have wheel hub, described primary blades and institute
State the circumference oblique of wheel hub.
Described primary blades size is more than described auxiliary blade dimensions.
It is preferred that the cross section of the blade being made up of described primary blades and auxiliary blade is y
Font, and the prong of y word is outside.
The invention has the beneficial effects as follows: the leaf of the jet mill high-effective classifying impeller blade structure of the present invention
Sheet is to be made up of primary blades and auxiliary blade, therefore, it is possible to effectively reduce eddy current, fall that blade produces
Low windage, and then improve yield and effectiveness of classification.

Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the blade section figure of the grading wheel of the present invention.
Detailed description of the invention
Embodiment: a kind of jet mill high-effective classifying impeller blade structure, including the front impeller disk 1, posterior lobe
Wheel disc 2 and some blades 3, described blade 3 is fixedly connected between the forward and backward impeller disk 1,2 and encloses
Becoming a circle, have charging seam between adjacent blades, the inner side of a circle blade forms cavity, each
Described blade 3 is all made up of a primary blades 31 and at least one auxiliary blade 32, described auxiliary blade 3
2 fixing connect (such as welding) in as described in primary blades 31 and and as described in there is angle between primary blades.
Each described blade is all made up of a primary blades and an auxiliary blade.
Described primary blades 31 is straight plate type vane.
The described front impeller disk and the described rear impeller disk have the circle of wheel hub, described primary blades and described wheel hub
All obliques.
Described primary blades size is more than described auxiliary blade dimensions.
The cross section of the blade 3 being made up of described primary blades and auxiliary blade is y font, and the prong of y word is outside
。
