Description
Technical field
The utility model relates to powder equipments, in particular to the airflow milling structure of powder disintegrating apparatus.
Background technique
Existing airflow milling is as shown in Figure of description 1 and 2, and powder material is by the feed opening above feeding section cylinder 3 along real
Heart dovetail arrow direction enters the inside of fluidized bed 1, is fluidized by being arranged symmetrically the supersonic airstream that high pressure nozzle 2 sprays to entrance
Powder material inside bed 1 provides kinetic energy, and powder material is mutually collided in the center of inside of fluidized bed 1, the powder after collision crashing
Body particle air-flow the solid dovetail arrow of drive lower edge upwardly through feeding section cylinder 3, and continue upwardly into and have classification
Casing body 4, after grading wheel is classified, qualified fine grained is entered inside grader head 6 by grading wheel through grader machine
Discharge port discharge above first 6, it is also necessary to which the fine grained for continuing the coarse granule crushed and part qualification can be centrifuged in grading wheel 5
Get rid of the inner wall to former grader shell 4 along filled arrows under the action of power, and fall along inner wall, by feeding section cylinder 3 into
Fluidized bed 1 continues mutually to collide with powder material under the action of supersonic airstream, with this repetitive cycling.It is existing this
Airflow milling structure, have of both it is insufficient, one, material after fluidized bed internal impact, mainly from shell central part edge
Axis flow up into classification wheel around, therefore, many powder granules can collide classification during flowing up
The lower end surface of wheel, which results in part conforming particles have been kept off, and does not arrive around grading wheel, returns to fluidized bed 1 and continues
By collision crashing, thus led to crushing；Two, after grading wheel is classified, it is also necessary to continue the coarse granule crushed and part
Qualified fine grained can get rid of the inner wall to former grader shell 4 along filled arrows under the action of 5 centrifugal force of grading wheel, and along
Inner wall falls, and in dropping process, if the effect of not upward auxiliary air, the conforming particle that part falls can also enter
Fluidized bed 1 continues collision crashing, thus leads to crushing；Powder, which is crossed, to be morcelled, and is not only reduced yield, the consumption energy, is ground to equipment
Damage crosses the particle crushed just into useless powder, can process operator to powder and make moreover, many powder material finished products are expensive
At huge economic loss.
Summary of the invention
The purpose of this utility model is that the deficiency for prior art scheme provides one by the improvement to its structure
Kind can be reduced powder material crossing in airflow milling crushing process and crush, and improve the airflow milling of yield rate and crush efficiency.
The technical solution of the utility model is:
It is a kind of reduced crush airflow milling, including fluidized bed 1, high pressure nozzle 2, feeding section cylinder 3, grading wheel 5, point
Grade machine head 6, which is characterized in that its fluidized bed 1 is equipped with 4 symmetrical high pressure nozzles 2 above；Fluidized bed upper end is same
It assembles the lower end of feeding section cylinder 3；Feeding section cylinder 3 is connected with the lower flange 7 of new airflow milling grader shell 12 above；New gas
Stream mill grader lower part of the housing is provided with blast pipe 10, and there is cone 9 in inside；There is guide ring 8 between lower flange 7 and cone 9；Water conservancy diversion
There is the gap of air inlet between ring 8 and lower flange 7；The inner circle of lower flange 7 is pyramidal structure, and between the outer circle of 9 lower end of cone
There is the gap of air inlet；New airflow milling grader enclosure interior middle and lower part position is provided with deflection cone 14, and deflection cone 14 is by being assemblied in
Feeding section cylinder 3 is supported with the deflection cone supporting rib 13 between lower flange 7 and is fixed；New 12 inner upper end of airflow milling grader shell
Equipped with grading wheel 5, new airflow milling grader shell 12 is connected with grader head 6 above.
When utility model works, powder material is by the feed opening above feeding section cylinder 3 along solid dovetail arrow direction
Into the inside of fluidized bed 1, by being arranged symmetrically supersonic airstream that high pressure nozzle 2 sprays into the powder entered inside fluidized bed 1
Raw material provides kinetic energy, and powder material is mutually collided in the center of inside of fluidized bed 1, and the powder granule after collision crashing is in air-flow
It drives the solid dovetail arrow of lower edge upwardly through feeding section cylinder 3, and continues up by 14 water conservancy diversion of deflection cone, into new air-flow
Grader shell 12 is ground with the stepped zone between grading wheel 5, after the classification of grading wheel 5, qualified fine grained passes through classification
Wheel enter grader head 6 inside through above grader head 6 discharge port be discharged, it is also necessary to continue crush coarse granule and
The qualified fine grained in part can be got rid of along filled arrows to new airflow milling grader shell 12 under the action of 5 centrifugal force of grading wheel
Inner wall, and fall along inner wall.Secondary Air enters cone 9 and new airflow milling grader shell 12 by valve 11, blast pipe 10
Annular housing between straight section lower inner wall and guide ring 8, under the action of guide ring 8, Secondary Air is uniformly from guide ring 8
Annular gap and lower flange 7 between lower flange 7 enter in 9 lower end of cone with the annular gap between 9 lower end outer circle of cone
Portion, and flowed to 5 direction of grading wheel.When the part finished particle in the powder granule of whereabouts by 9 inner wall lower end of cone when
It waits, will be blown afloat again by Secondary Air, and be again introduced into grader region with the air-flow of uplink and be classified.In the powder of whereabouts
Coarse granule, because partial size is big, quality is big, is difficult to be blown afloat by Secondary Air when passing through 9 inner wall lower end of cone, these coarse granules
It will continue to fall, enter fluidized bed 1 by feeding section cylinder 3, continue under the action of supersonic airstream mutual with powder material
Collision crashing, with this repetitive cycling.
The utility model has been effectively prevented the punching of uplink powder granule by the way that deflection cone 14 is arranged inside classification casing 12
It to 5 lower end surface of grading wheel, and is difficult to reach region between grading wheel classification 5 and grader shell, is forced back fluidized bed after continued powder
It is broken, to cause the deficiency crushed.By the special designing to new airflow milling grader shell 12, so that along classification after classification
The part conforming particle of inner walls whereabouts powder section Teller can be blown afloat by Secondary Air again, into stepped zone, be avoided
Conforming particle falls into impact several times in fluidized bed, leads to crushing.Crushing problem was improved, can be improved the production of airflow milling
Amount reduces energy consumption.It is stringent to size controlling because many powder materials and powder finished product are expensive, once conforming particle crosses powder
It is broken, yield rate will be reduced, causes heavy losses, therefore, made by the utility model to powder processing and operator
Crushing is improved, and good economic benefit can be obtained.
