Technical field
The utility model relates to the pulverizer in a kind of feed manufacturing machine field, particularly a kind of anti-clogging pulverizer.
Background technology
At present, feed is pulverized to the main pulverizer that adopts of processing, existing pulverizer comprises grinding rotor, rotor is arranged on rotor main shaft, main shaft two ends are supported in frame by bearing block, hammer frame plate is installed on main shaft at regular intervals, on hammer frame plate, be evenly distributed with a plurality of pin shaft holes, bearing pin is installed in pin shaft hole, hammer leaf is arranged on bearing pin and by spacer and is spaced from each other, rotor periphery is provided with the sieve of the densely covered mesh that surrounds rotor, and sieve is surrounded as the enclosure space formation pulverizing chamber that is greater than root diameter.
During pulverizer work, main shaft drives hammer frame plate to drive the hammer leaf high speed rotating being contained on bearing pin, hammer leaf centrifugal development simultaneously.Material enters pulverizing chamber through feeding equipment from the charging aperture at pulverizer top, the decrease speed of material is lower, when entering the fracture area of pulverizing chamber, contact with hammer leaf, the linear velocity of hammer leaf is higher, it is broken because both huge speed differences cause material to overwhelm, then, material flies to sieve under the effect of centrifugal force, again bump with sieve, by bulky grain, become granule, pulverized small particles material, through the sieve aperture of sieve, under the effect of gravity and auxiliary air draft system, is discharged from discharging opening.
Because material is when doing high speed centrifugation motion, can form one along the circulation layer of compass screen surface rotation, circulation layer has reduced the relative velocity of hammer leaf strike material, weakened the validity of hitting, material in circulation layer periphery has departed from the strike of hammer leaf, and at the every bit of circulation layer, the circular arc tangent plane of sieve is identical with material stream motion tangential direction, cause not malleable direction of material, be difficult to hinder the formation of circulation layer.For the less pulverizer of powder particle, in use for some time, the easy Partial Blocking of the eyelet of sieve or aperture diminish, by sieve hole material out, will reduce, yield reducation, in sieve, temperature of charge rises, repeating to pulverize increases, and specific yield energy consumption raises.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of anti-clogging pulverizer is provided, and can effectively dredge the eyelet of sieve, improves and pulverizes and discharging efficiency.
For solving above technical problem, a kind of anti-clogging pulverizer provided by the utility model, comprise the rotor and the pulverizing chamber of envelope outside rotor that are provided with hammer leaf, described pulverizing chamber by multi-disc sieve and fixedly the sieve support of sieve form, pulverizing chamber top is provided with charging aperture, between described hammer leaf and described sieve, leave gap, on the wallboard of described pulverizing chamber, be at least provided with a spray orifice, the axis of described spray orifice is parallel to the axis of described rotor, and the gap described in the position alignment of spray orifice between hammer leaf and described sieve, the external port of described spray orifice is connected with jet pipe, described jet pipe is communicated with compressed air gas source.
With respect to prior art, the utility model has been obtained following beneficial effect: to spray orifice intermediate gap, pass into the compressed air of high pressure, first circulation layer is destroyed, strengthened the relative velocity between material and hammer leaf, improved crushing effect; Secondly, compressed air gap spray the pressure initiation pulse in pulverizing chamber, gets lodged in powder in sieve eyelet and is subject to vibrating and easily comes off, and has improved the discharging efficiency of sieve; Temperature of charge in pulverizing chamber declines simultaneously, repeats to pulverize and reduces, specific yield Energy Intensity Reduction.
As preferred version of the present utility model, described spray orifice is positioned at the middle part of described pulverizing chamber short transverse.Compressed air can alignment ring fluid layer middle part blow out.
As preferred version of the present utility model, dock with the upper end of described sieve by castellated plates described charging aperture lower end, and described spray orifice is positioned at the middle part of described castellated plates short transverse.Compressed air can alignment ring fluid layer top blow out.
As preferred version of the present utility model, described spray orifice is symmetrical arranged centered by the vertical axis of described rotor.Compressed air can carry out disturbance to two of circulation layer sustained height sections simultaneously.
As preferred version of the present utility model, described spray orifice is symmetrical arranged on the wallboard of the both sides of described pulverizing chamber.Compressed air can spray in opposite directions from both sides wallboard, more balanced to the disturbance of circulation layer.
