Specific embodiment
The utility model provides a kind of Efficient air flow impact grinding.Technical solutions of the utility model are carried out below in conjunction with attached drawing
Detailed description, so that it is more readily understood and grasps.
A kind of Efficient air flow impact grinding, as depicted in figs. 1 and 2, including pulverizer main body 1, pulverizer main body 1, which is equipped with, to be crushed
Cabin 2 and compressed air disintegrating mechanism, compressed air disintegrating mechanism include that supply air line 3 and at least three crush nozzle 4, crush cabin
2 are equipped with the feeding-passage 5 outside connection and the tapping channel 6 outside connection, tapping channel 6 and point for crushing 2 inner top of cabin
Step cone 7 is connected, and the nozzle end for crushing nozzle 4 passes through the bulkhead for crushing cabin 2 positioned at crushing inside cabin 2, crushes the inlet end of nozzle 4
It is connected positioned at 2 outside of crushing cabin and with supply air line 3.
Each section connection relationship and pulverization principle of high pressure draught disintegrating apparatus belong to the prior art, and details are not described herein.
It all crushes nozzle in this case to be evenly distributed on the bulkhead for crushing cabin 2, and initial end crushes nozzle and end
1/4 ~ 1/2 of the cambered surface between nozzle away from the bulkhead perimeter for crushing cabin is crushed, the injection direction of at least three crushing nozzles 4 is
With circle tangent line, the high speed rotation region 9 being formed in 8 locations of tangent line circle in cabin 2 is crushed.
It specifically describes, the high pressure draught sprayed by least three crushing nozzles 4 can form high speed around tangent line circle 8
Rotary area 9 crushes nozzle 4 and carries out impact comminution to the material in high speed rotation region 9, and the injection for crushing nozzle 4 is superposition
Ground form avoids the presence of the interference crushed between 4 jet-stream wind of nozzle, reduces unnecessary energy loss, high speed rotation region 9
The sphere of circulation of dust air-flow is limited, situations such as being vortexed miscellaneous stream can be prevented, the random operation of dust particles is reduced and collides
Damage crushes the possibility of 2 inner part of cabin.
By the way of concentrated setting, nozzle concentrated setting will be crushed within the scope of 1/4 ~ 1/2 bulkhead, so that impact zone
Separately with gentle shunting zone, it is well known that under the action of having impact force, the small particles material power that is affected is larger,
Sedimentation separation can not be generated in impact range between bulky grain, therefore this case uses and is less than half secondary crushing nozzle setting.
By the powder of impact zone by concentration impact comminution, and at gentle shunting zone, bulky grain and little particle can be produced
It is born from and so rises and settle, to be easy to material layering, little particle enters grading wheel and bulky grain still falls in high speed rotation area
In domain 9.
The high speed rotation region 9 is more suitable for the material occurred across property amount, such as white carbon black, talcum powder, TGIC
Industrial chemicals.
In preferred embodiment, the projection of 5 feedstock direction of feeding-passage and tangent line circle 8 are tangent, and particle can be made by being designed in this way
Larger heavier material, which is directly drop in high speed rotation region 9, to be crushed.It should be noted that the mouth end of feeding-passage 5
Positioned at the top in high speed rotation region 9.
In the preferred embodiment of this case, as shown in figure 3, crushing, there is a high position in nozzle 4 and low level is distinguished, and high-order crush is sprayed
Mouth and low level crush nozzle and are separately arranged.
A high position crushes nozzle and high speed rotation region 9 is divided into two regions being mutually crosslinked, many institutes with low level crushing nozzle
It is known, crush the injection of nozzle as point impact, and bulky grain in high speed rotation region 9 there are certain area distribution, and it is former
The point impact of the contour crushing nozzle come is monocycle path, and this case can form bicyclic path impact, i.e., in high speed rotation region 9
In the presence of the twice impact ring just having differences, to increase the probability of directly impact bulky grain, while height is not interfered with again
Air turbulence in fast rotary area 9, improves crushing effect.
It is highly preferred that compressed air disintegrating mechanism includes that odd number crushes nozzle 4, and the high-order nozzle quantity that crushes is than low
Position crushing nozzle quantity is one big, and it is in order to enable airflow circulating is in propradation that a high position, which crushes more one, nozzle, and a high position is rushed
It is i.e. larger to hit the larger air-flow that it is generated of power, is easy the thin material lifting of low level, and biggish particle is easy retention in
Lower layer, thus by biggish impact.
In addition, crushing cabin 2 is equipped with the taper guide wall 10 for rising guiding for powder supply dust and gas stream.The taper guide wall 10
For relatively thin lighter rising dust guiding 7 region of grading wheel to be carried out separation discharging.
It is equipped with disintegrating mechanism in taking turns in another preferred embodiment of this case, in grading wheel 7, the crushing is omitted in attached drawing
The diagram of mechanism.
Specifically realization principle, grading wheel 7 are in high speed rotation state, carry out dust screening point by powerful centrifugal force
From, but traditional grading wheel 7 only has centrifugation, leads to its high-speed rotating energy dissipation, this case is set in grading wheel 7
Disintegrating mechanism in wheel has been set, disintegrating mechanism, which can be, in the wheel adds mechanism, the deformation being also possible on origianl structure part, such as
Blade is set on structural support in grading wheel 7, under 7 high speed rotation state of grading wheel, blade can impact cutting crushing wheel
Interior dust, to improve the crushing effect of grinding device.
Protective device can be set in this case, for example, pulverizer main body 1, which is equipped with, crushes cabin protective cover 11.Pulverizer main body 1
It is equipped with supply air line protective cover 12.External collision can be prevented by these protective covers, protects grinding device.
Finally, this case can also advanced optimize, visual windows are set on crushing cabin 2, it can be intuitively from outside
To the crushing situation crushed in cabin 2.
By above description it can be found that a kind of Efficient air flow impact grinding of the utility model, by crushing nozzle to high speed
Material in rotary area carries out crushing impact, can improve the crush efficiency for crushing uniformity coefficient and improving material of material, and
Energy consumption is effectively reduced.It is arranged using high-order and low-profile crushing nozzle, so that there are high-low-position friendships in high speed rotation region
Connection improves the direct impact probability to big material, to improve crush efficiency, while not interfering with whole flow path.It is more suitable
For there is the material crossing over property amount and occurring.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality
Within novel protection scope.
