Description
Technical field
The present invention relates to a kind of mechanical device that grain, feed etc. is carried out fragmentation, particularly a kind of pulverizer.
Background technology
In the prior art, be used for the pulverizer of grain and feed, it mainly includes housing, housing top offers charging aperture, is provided with rotor in the housing, and the rotor outward flange is provided with some hammer leaves, rotor periphery semi-surrounding is provided with the sieve sheet, forms pulverizing chamber, and sieve sheet top is connected with the transition of charging aperture downside.During this device work, material enters in the pulverizing chamber from the charging aperture on sieve sheet top, rotor high-speed rotates, hammer leaf repeatedly hits pulverizing with material, material is made the high speed circular motion in pulverizing chamber, form a materials flow layer along the compass screen surface rotation, this materials flow layer is called circulation layer, under centrifugal action, 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, and oarse-grained material stops that short grained material passes the sieve sheet, and pulverizer efficient is reduced; Simultaneously because short grained material can not pass sieve aperture, cause its in pulverizing chamber by the hammer leaf multiple impact, temperature raises, and brings the potential safety hazard of fire, high temperature also can destroy the trophic component of material, has influence on the quality of crushing rear material.
For improving the screening efficiency of material, just circulation layer need be destroyed, oarse-grained material is reentered in the strike zone of rotor, short grained material can arrive compass screen surface more; We work out a kind of high-voltage pulse pulverizer, and its structure mainly includes housing, and housing top offers charging aperture, are provided with rotor in the housing, and the rotor periphery is provided with the sieve sheet of semi-surrounding rotor, form pulverizing chamber, and sieve sheet top is connected with the transition of charging aperture downside; Be positioned at sieve sheet extension circumference upside in the described charging aperture and be provided with some nozzles that directly blow to circulation layer.Enter air pulse from nozzle, air pulse can form instant impact, directly impacts big particle, makes its periphery that breaks away from circulation layer, and enters in the strike zone of rotor, and short grained material obtains more that multimachine can move to skin, to improve screening efficiency; The direction of air pulse is that the direction of device air draught together is in the same way, can not produce interference between the two, can increase the material velocity through screen on the contrary, simultaneously, has guaranteed that also air pulse has good impact effect.In test, we find at the pulverizer that does not have air pulse to impact, the hammer leaf of its rotor periphery is the ecto-entad wearing and tearing, and have a pulverizer that air pulse impacts circulation layer, the hammer leaf of its rotor periphery maximum position of wearing and tearing is being located from about the 30mm～40mm of hammer leaf end, be to move in the hammer leaf abration position, can prove absolutely that the pulverizing function that has air pulse impact circulation layer obtains better technique effect, but, in the bigger position of hammer leaf wearing and tearing, its intensity must descend, and the high speed centrifugation athletic meeting causes the hammer leaf distortion, distortion, even fracture, the gap of original hammer leaf and sieve sheet is just smaller, in case distortion appears in hammer leaf, distortion, the problem of fracture will smash the sieve sheet, causes fault.
Summary of the invention
The invention provides a kind of turbulence pulverizer, it can directly be destroyed circulation layer,, simultaneously, can also guarantee that the wearing and tearing of hammer leaf are even, prolong the service life of hammer leaf with the screening efficiency of further raising material.
The object of the present invention is achieved like this: a kind of turbulence pulverizer, comprise housing, and housing top offers charging aperture, be provided with rotor in the housing, the rotor periphery is provided with the sieve sheet of semi-surrounding rotor, and sieve sheet and rotor constitute pulverizing chamber, and sieve sheet top is connected with the transition of charging aperture downside; Be positioned at sieve sheet extension circumference upper horizontal in the described charging aperture and be provided with rotating air inlet pipe, air inlet pipe one end links to each other with electromagnetic valve outlet through swivel joint, compressed air gas source is connected in the import of magnetic valve, is arranged at intervals with some nozzles towards pulverizing chamber on the air inlet pipe; Described air inlet pipe links to each other with a rotating mechanism.
When this device uses, infeed compressed air by magnetic valve to air inlet pipe, compressed air forms impact air-flow through nozzle and is blown in the pulverizing chamber, directly impact the circulation layer of material, make the periphery of oarse-grained disengaging circulation layer, and enter in the strike zone of rotor, short grained material obtains more that multimachine can move to skin, to improve screening efficiency; In this process, rotating mechanism drives air inlet pipe and rotates, in the air inlet pipe rotation process, the airflow direction of nozzle constantly changes, and the angle of attack and the dynamics of circulation layer all changed, therefore, the angle and the position of the hammer leaf of rotor periphery and circulation layer bump are all constantly changing, and make hammer leaf all can obtain the strike chance of equiprobability from outside to inside, like this, hammer leaf weares and teares evenly from outside to inside, and prolong its service life.In this pulverizer, the screening efficiency height of material, the hammer leaf long service life can be used for various material grinding processing such as grain, feed.
Described rotating mechanism can have following structure: one, this rotating mechanism comprise the cylinder that is hinged on outside the housing, and the piston rod end of cylinder and rocking arm one end are hinged, and fixedly connected in the rocking arm other end air inlet pipe end outer with stretching out housing.Its two, described rotating mechanism comprises and is hinged on the outer cylinder of housing, the piston rod end of cylinder is connected with tooth bar, described tooth bar is arranged in the fixing outward slide rail of housing, air inlet pipe is stretched out housing end outward and is provided with the gear that is meshed with described tooth bar.Above-mentioned two technical schemes all can make and make nozzle to be blown into compressed air towards circulation layer by air inlet pipe rotational angle in the certain angle scope, form disturbance.
Not easy to wear for guaranteeing air inlet pipe, it is 10-30mm that described air inlet pipe is extended circumferential distance with the sieve sheet.Air inlet pipe is too far away with sieve sheet extension circumferential distance, the impact air-flow diffusion, and percussion weakens, and is too near, and then circulation layer touches air inlet pipe easily, causes the air inlet pipe excessive wear.
As a further improvement on the present invention, described air inlet pipe respectively is provided with one in the charging aperture bilateral symmetry.When the rotor positive direction is rotated, can use wherein air inlet pipe air inlet, during the rotor reverse rotation, can use another root air inlet pipe air inlet, also can two air inlet pipe work simultaneously.
