Abstract
The utility model provides a crusher rotor which improves the separation velocity of rotary material so as to improve the crushing efficiency. The crusher rotor mainly comprises a main shaft, a plurality of hammer carrier plates, a plurality of hammer slices and an impeller, wherein the hammer carrier plates are fixed on the main shaft and are uniformly arranged at intervals; the hammer slices are fixedly arranged on the hammer carrier plates; the impeller is sheathed and arranged on the main shaft among the hammer carrier plates; the impeller comprises a spacer bush, a plurality of blades and side plates; the spacer bush is sheathed and arranged on the main shaft; the blades are uniformly arranged at the outer periphery of the spacer bush; and the side plates are fixed on the front end surface and the back end surface of the spacer bush. When in work, the impeller rotates along with the rotor to drive the blades to rotate, a certain air flow is formed to blow the air in a crusher to the crushed material, thereby breaking the original spacer bush of the material, improving the screening efficiency of the material and reducing the over crushing caused by non-screening of the material, so as to improve the yield of the crusher.
Description
Technical field
The utility model relates to the hammer leaf disintegrating apparatus of grain feed manufacture field, relates in particular to the rotor in the hammer leaf disintegrating apparatus.
Background technology
The rotor of existing beater disintegrating machine mainly comprises main shaft, is fixed on the main shaft and the hammer frame plate that evenly is provided with at interval, is fixed with some hammer leaves on the hammer frame plate.In crushing process, rotor mill rotates at a high speed, with epitrochanterian hammer leaf centrifugal development, smashes material by hammer leaf, by the comminuting matter discharge of the sieve aperture on the sieve sheet of envelope pulverizing chamber again, finishes the pulverizing function of pulverizer.Its weak point is: during work; the rotor high-speed rotation; when the drive material is made the high speed circular motion; can form a materials flow layer along the compass screen surface rotation; this materials flow layer is called circulation layer, and the bulky grain in the material can accumulate in the circulation layer periphery under centrifugal action, and short grained material accumulates in the circulation layer inboard easily; oarse-grained material stops that short grained material passes the sieve sheet, and pulverizer efficient is reduced.
Summary of the invention
The utility model provide can improve at a high speed rotation feed separation speed to reach a kind of rotor mill of purpose that improves crush efficiency.
The utility model purpose is achieved in that a kind of rotor mill, comprise main shaft, be fixed on the main shaft and the some hammer frame plates that evenly are provided with at interval, be fixed with some hammer leaves on the hammer frame plate, be set with impeller on the main shaft between the described hammer frame plate, described impeller comprises fixing side plate on circumferential even some blades that are provided with of the spacer, the spacer periphery that are sleeved on the main shaft and the spacer rear and front end face.
During work, after material is hit by hammer leaf, hit into particles of different sizes along with hammer leaf moves together, the impeller between hammer frame plate also rotates along with the rotation of main shaft simultaneously.Drive blade rotation during wheel rotation, form certain air-flow, the air in the pulverizer is blowed to pulverized material, broken the original circulation layer of material, improve the efficient that material goes out to sieve, reduced material and do not gone out the excessive pulverizing that sieve causes, thereby improved the output of pulverizer.
As further optimization of the present utility model, described blade can be a linear, also can be shaped form.Can also evenly be provided with some gas-permeable channels on the blade, described gas-permeable channels can be to run through groove or through hole, to increase through the ventilation on the impeller, further destroys the circulation layer of material, improves crush efficiency.

The specific embodiment
As shown in Figure 1, a kind of rotor mill comprises main shaft 3, is fixed on the main shaft 3 and the some hammer frame plates 4 that evenly are provided with at interval, is fixed with some hammer leaves 1 on the hammer frame plate 4, also is set with impeller 2 on the main shaft 3 between the described hammer frame plate 4.
As shown in Figure 2, this impeller 2 comprises the spacer 6 that is sleeved on the main shaft 3, some blades 5 and the fixing side plate 7 of spacer 6 rear and front end faces that spacer 6 peripheries circumferentially evenly are provided with, and described blade 5 can be linear, also can be shaped form.In addition, can also evenly or disperse on this blade 5 and be provided with some gas-permeable channels that run through groove or through-hole form, to increase through the ventilation on the impeller.
During this rotor mill work, after material is hit by hammer leaf, hit into particles of different sizes along with hammer leaf moves together, the impeller between hammer frame plate also rotates along with the rotation of main shaft simultaneously.Drive blade rotation during wheel rotation, form certain air-flow, the air in the pulverizer is blowed to pulverized material, broken the original circulation layer of material, improve the efficient that material goes out to sieve, reduced material and do not gone out the excessive pulverizing that sieve causes, thereby improved the output and the efficient of pulverizer.
