Abstract
It the utility model is related to grader equipment technical field, and in particular to a kind of center of gravity sunk type grading wheel, including：Grading wheel main shaft (1), it is classified impeller blade (2), grading wheel gusset (3), center of gravity sinking section (4), sunk type brace rod (5), peaceful dead zone (6), after sunk type brace rod, a sinking clearance zone is createed to grading wheel, on the one hand the decentralization of overall grading wheel is made, the stability that it runs at high speed is more preferable, grading wheel is set to can reach higher rotating speed, required with adapting to thinner and more accurate classification, in the material that processing also requires that, only need to be arranged to the 70% of traditional classification wheel speed again using this grading wheel, reduce the mechanical fatigue of equipment operation, extend service life.On the other hand increase also grading wheel inner space, make interior circulation of the material inside grading wheel more abundant, be favorably improved the dispersiveness of material.
Description
Technical field
It the utility model is related to grader equipment technical field, and in particular to a kind of center of gravity sunk type grading wheel.
Background technology
Grading wheel, material moves to graded region under blower fan draft effect with ascending air, in the classification whirlpool of high speed rotation
Under powerful centrifugal action caused by wheel, make thickness feed separation, the fine grained for meeting granularity requirements enters rotation by grading wheel
Wind separator and deduster are collected, and coarse granule, which drops to disintegrating area, to be continued to crush, and material is under blower fan draft effect with rising gas
Stream moves to graded region, under powerful centrifugal action caused by the stage turbine in high speed rotation, makes thickness feed separation, meets
The fine grained of granularity requirements enters cyclone separator by grading wheel and deduster is collected, and coarse granule drops to disintegrating area and continues powder
It is broken.
Motor driven grading wheel is rotated in classification housing high speed, and powerful centrifugal force is formed in grader.Enter
Primary mixture in grader is introduced into inside grading wheel, under the influence of centrifugal force, big or weight particle centrifugalization
Power is big, therefore is got rid of to grading wheel periphery to grader side wall, and is no longer influenceed by centrifugal force, falls on and is crushed in main frame under nature
Continue to crush or under fall on discharging opening and be collected；Small or light material is small by centrifugal action, is hovered inside grading wheel,
Drawn windage by air-introduced machine and be taken to eminence, moved along pipeline to being graded or collect in next component.By becoming frequency modulation
The rotating speed of section grading wheel can adjust the size of centrifugal force in grader, reach the purpose for the material for separating designated size
Grading wheel is the core component of gas flow sizing machine, and existing grading wheel upper surface is generally level design, because of its center of gravity
It is higher, therefore running speed is not high, generally 4500 rpms, higher rotating speed can bring higher machinery because of the limitation of its structure
A series of problems, such as fatigue and vibration.And relatively low rotating speed may not apply in the ultra tiny and application of high precision.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of center of gravity sunk type grading wheel, include：Grading wheel master
Axle, classification impeller blade, grading wheel gusset, it is characterised in that：The grading wheel the superiors grading wheel gusset and grading wheel main shaft top
End there are distance, and the distance between described the superiors' grading wheel gusset and grading wheel main shaft are center of gravity sinking section, the superiors
Grading wheel gusset is connected with second layer grading wheel gusset by sunk type brace rod, the sky that described sunk type brace rod surrounds out
Between be peaceful dead zone.
Preferably, the angle angle of described grading wheel gusset and sunk type brace rod is 40-45 degree.
Preferably, described grading wheel main shaft is 63132RS axles.
Compared with prior art, the utility model has the advantages that：Under a kind of center of gravity that the utility model uses
Heavy formula grading wheel, is remarkably improved the defecation rate and sharpness of separation of material, significantly improves yield rate, and improve to a certain extent
Treating capacity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is existing grading wheel and contrast schematic diagram of the present utility model；
In figure：It is grading wheel main shaft 1, classification impeller blade 2, grading wheel gusset 3, center of gravity sinking section 4, sunk type brace rod 5, heavy
Quiet dead zone 6.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：
Embodiment：
As shown in Figure 1
A kind of center of gravity sunk type grading wheel of the present utility model, including：Grading wheel main shaft 1, classification impeller blade 2, grading wheel
Gusset 3, center of gravity sinking section 4, sunk type brace rod 5, peaceful dead zone 6, the grading wheel the superiors grading wheel gusset and grading wheel
Main shaft top there are distance, and the distance between described the superiors' grading wheel gusset and grading wheel main shaft are center of gravity sinking section,
The superiors' grading wheel gusset is connected with second layer grading wheel gusset by sunk type brace rod, and described sunk type brace rod surrounds
The space gone out is peaceful dead zone.
It is of the present utility model to be further arranged to：The angle angle of described grading wheel gusset and sunk type brace rod is
40-45 degree.
Sunk type grading wheel master is by grading wheel most last layer reinforcement, by traditional planar design, is improved to tilt
Sunk type and second layer link of boards.After sunk type brace rod, a sinking clearance zone is createed to grading wheel, on the one hand
Make the decentralization of overall grading wheel, the stability that it runs at high speed is more preferable, grading wheel is can reach higher rotating speed, to adapt to
Thinner and more accurate classification requires, in the material that processing also requires that, only needs to be arranged to traditional again using this grading wheel
The 70% of wheel speed is classified, the mechanical fatigue of equipment operation is reduced, extends service life.On the other hand also make in grading wheel
Portion space increases, and makes interior circulation of the material inside grading wheel more abundant, is favorably improved the dispersiveness of material.
Using technical scheme described in the utility model, or those skilled in the art is in technical solutions of the utility model
Under inspiration, similar technical scheme is designed, and reaches above-mentioned technique effect, is to fall into protection model of the present utility model
Enclose.
