When rotor 5 rotates, the cutting blade 511 on grinding rotor 5 is matched with the ledger-plate 611 crushed on stator 6, so as to continue
Ground material is worn into material particles.
In order to enable the distance between ledger-plate 611 and cutting blade 511 are adjustable, to adapt to the material of variable grain size,
The both ends of second crushing rotary drum 610 are respectively equipped with the first mounting ring and second mounting ring, the first mounting ring and second
Corresponding in mounting ring to open up grooved hole, 611 both ends of ledger-plate correspond on the slot and second mounting ring of insertion the first mounting ring
In slot.
In order to quantify the adjustable range of ledger-plate 611, the precision of adjusting is improved, along the slot edge in slot recess direction
Equipped with scale.
As shown in Figure 1, the pulverizing chamber 210 is enclosed in the periphery of grading room 220, the inlet plenum 1 is located at pulverizing chamber 210
With the lower section of grading room 220, the gas of low temperature is able to enter inlet plenum 1, and the cryogenic gas can first be full of pulverizing chamber 210,
Grading room 220, and the material for formation being ground in pulverizing chamber 210 are flowed by the pulverizing chamber 210 for being located at 220 periphery of grading room again
Particle is brought into grading wheel 7, and miniature material particles are as the swirling eddy of grading wheel 7 is from 3 row of discharge port under the rotation of grading wheel 7
Out, the material particles for being unsatisfactory for grain graininess requirement are thrown under the action of the centrifugal force on the inner wall of grinding rotor 5, and fraction is thick
Particle is produced from the first recirculation hole 512 on grinding rotor 5, and most of material particles decline along the inner wall of grinding rotor 5.
As shown in Figure 1, being slid in order to prevent to the material accumulation of 220 bottom of grading room, 220 bottom of grading room is also set
There is vortex platform 12, the edge of the vortex platform 12 forms a circle guide surface, and vortex platform 12 is mounted on the first drive shaft 8
On, it can be rotated together with grinding rotor 5 and the first drive shaft 8, with the rotation of vortex platform 12, fall in vortex platform 12
On biggish material particles along vortex 12 edge of platform guide surface slide, and under the drive of air-flow biggish material from
The second recirculation hole 521 on grinding rotor 5 reenters the crushing of the progress of pulverizing chamber 210 again.
According to above structure and size preferred design, the present invention provides following preferred embodiment: crushing in separation chamber 2
Diameter is 500 mm, and 5 diameter of grinding rotor is 350 mm, and the effective cutting length of ledger-plate 611 and cutting blade 511 is 400 mm,
5 revolving speed of grinding rotor is 1300 r/min, and the revolving speed of grading wheel 7 is 3000 r/min, and the air intake after water cooling is 800
m3/ h, installed power are 25 kW.Such as when crushing oat with the present invention, oat will first pass through coarse crushing, be less than feed size
3 mm, the size distribution of product is 100 ~ 500 mesh after crushing, and the output of oat is in 10 ~ 100 kg/h.
The course of work of the invention is as follows: cryogenic gas is sent into from inlet plenum 1, and then the second motor 11 drives the second driving
Axis 9 rotates, and the second drive shaft 9 drives grading wheel 7 to rotate, meanwhile, first motor 10 drives the rotation of the first drive shaft 8, and first drives
Moving axis 8 drives grinding rotor 5 to rotate.After system is stablized, material enters from feed inlet 3, in ledger-plate 611 and cutting blade 511
Between carry out shearing crushing, smashed material particles rise with the cryogenic gas that inlet plenum 1 is come in, and reach upper end fixed plate
After 520, enter inside grading room 220 from the second recirculation hole 521 in fixed plate 520；After material particles enter grading room 220,
Under the action of grading wheel 7, smashed fine grained enters discharge port 4 in the middle part of grading wheel 7, is unsatisfactory for grain graininess requirement
Material particles are thrown under the action of the centrifugal force on the inner wall of grinding rotor 5, and fraction coarse granule is from first on grinding rotor 5
Recirculation hole 512 produces, and most of material particles decline along the inner wall of grinding rotor 5, and under the action of being vortexed platform 12,
The bottom margin of grinding rotor 5 is rotated to, it at this moment can be by thick object from the cryogenic gas that the inlet plenum 1 of 12 lower section of vortex platform is sent into
Material particle is all discharged from the first recirculation hole 512 of 5 lower part of grinding rotor, and the rough material particle after discharge is again introduced into crushing
Room 210 carries out shearing crushing, repeats the above process, and until material particles meet granularity requirements, is finally completed finely cutting for material
It cuts and is separated with particle.
It should be understood by those ordinary skilled in the art that: the above is only a specific embodiment of the present invention, and
It is not used in the limitation present invention, all any modification, equivalent substitution, improvement and etc. within purport of the invention, done should all include
Within protection scope of the present invention.
