The mechanism of crushing be rotary speed reach 5500r/min grating disk 2 can with the gear ring of the side wall of crushing chamber 1 it Between form orthogonal eddy flow, specifically, the first eddy flow can be formed around the first gear ring, the position of the first cutter head 7 can shape Into the second eddy flow, the direction of the first eddy flow and the second eddy flow is vertical, meeting in the space between the rack 5 of cutter 6 and first Huge mastication forces are formed, can thus tear solid particle turns into smaller particle.

As further improvement of this embodiment, the first described cutter head 7 is arranged horizontally, and the first described rack 5 hangs down It is straight to be arranged in horizontal plane.So set and be advantageous in that, the first cutter head 7 is horizontally disposed can to reduce air drag, reduction for The load of motor.

In the present embodiment, described charging aperture 3 is arranged on the center of roof, and described discharging opening 4 is arranged on bottom plate Center, described crushing chamber 1 is cylinder, and the height of the first described rack 5 is 11cm, perpendicular to the length of the first rack 5 The section in direction is triangle.Certainly in actual applications, according to the size and scale of equipment, the height of the first rack 5 is can With what is flexibly changed, to this without excessively limiting.Specifically, multiple first cutter heads 7 are in turn connected to form wavy shaped configuration, if The radian for putting the surface of the first cutter head 7 is 2.5-5 °, and in favor of coordinating with the side of crushing chamber 1, the height of described cutter 6 is 40mm, the upper and lower surface for being distributed in grating disk 2 of cutter 6 alternatively up and down.Such cutter 6 and grating disk 2 of arrangement up and down The thickness of disk body 8 is added the height for being slightly less than the first rack 5, as principle, the height that the height of cutter 6 will be with the first rack 5 Degree is adapted, if equipment is amplified, related data will also do corresponding amplification.

In the present embodiment, described grating disk 2 includes disk body 8, and described cutter 6 is arranged on the edge of disk body 8, described The upper surface of disk body 8 be evenly distributed with multiple the first blades 9 arranged in a ring；The described lower surface of disk body 8 is uniformly distributed There are multiple the second blades 10 arranged in a ring, described the first blade 9 and the second blade 10 is arc.

Here, it is emphasized that the particle that the first blade 9 inputs charging aperture 3 rapidly imported into the margin location of grating disk 2 Put, meanwhile, speed during particle arrival 2 edge of grating disk is very big, can improve crushing effect.

Second blade 10 is mainly used for being flowed back, more particularly suitable, and described multiple first blades 9 are in disk body 8 Heart position surrounds one and enters material space 11, and described multiple second blades 10 surround a discharge space in the center of disk body 8 12, connect on described charging aperture 3 and connect oriented powder on the upper baffle liner 13 of extension in oriented crushing chamber 1, described discharging opening 4 The lower baffle liner 14 of extension in broken chamber 1, described upper baffle liner 13 is extended into material space 11, described lower baffle liner 14 Extend in discharge space 12.By in this way, lower baffle liner 14 can play stop larger particles directly through discharging opening 4 Discharge, discharging opening 4 simply by particle reach nano level particle with air-flow discharge, it is necessary to illustrate, the present embodiment and In conventional art, discharging opening 4 is all the blower fan for needing to connect negative-pressure ward, and larger particle is in uphill process, second The edge of grating disk 2 can be thrown in the presence of the drive of blade 10 and centrifugal force, separating twice is carried out.So improve and crush effect Really.

Need exist for it is stressed that the length of the second described blade 10 is than the long 10-20mm of length of the first blade 9, The length substantially 170mm of second blade 10,10mm is about than the first blade 9.Such benefit is being crushed to improve particle Holdup time in chamber 1.

Specifically, fluid can be rapidly dispersed into the edge of disk body 8 by the first blade 9, and the second blade 10 can be by fluid The edge of disk body 8 is recycled back to, because discharge space 12 is located at the lower surface of disk body 8, generally, discharging is all by that can produce The blower fan of raw negative pressure provides flow of fluid power.In the case of the machine that do not blow in, rotating grating disk 2, we can be found that gas is Flow to what is gone above from down, the direction under this is flowed to fluid in normal production from above is different, and so we may safely draw the conclusion, The second longer blade 10 can produce relatively large air pressure.This phenomenon be applied in actual production will produce it is more peculiar Effect, i.e., blower fan produce negative pressure, the fluid of the lower surface of grating disk 2 has the trend flowed downward, while the second blade 10 compares Long, fluid is provided simultaneously with the trend flowed up again, in this case, and lighter particle enters blower fan with negative pressure fluid In, heavier particle is poor due to mobility, can smoothly return to crushing in the case of the mechanicals efforts of the second blade 10 The edge of disk 2, which improves the reflowing result of large granular materials.The effect of separating twice can be so effectively improved, is prevented Only excessive large-size particles are escaped from discharging opening 4.
