Description

Bidentate ring micronizer
Technical field
The utility model patent is related to milling machinery technical field, especially a kind of ultramicro grinding with bidentate coil structures Machine.
Background technique
Micronizer is the interaction utilized between high-speed rotating tup and the gear ring of fixation at present, including is hit It hits, crumple, shearing, tearing to realize the equipment to stemness material superfine comminution.It is by cylindricality pulverizing chamber, expansion chamber, rotor, tooth The composition such as circle, grading wheel.Material enters cylindricality pulverizing chamber by feed inlet, by between high-speed rotating tup and the gear ring of fixation Interaction, including shock, rubbing, shearing, tearing realize to stemness material superfine comminution.Pulverized material passes through wind Negative pressure gas flow caused by machine takes pulverizing chamber out of, into feed separation collection system, completes to crush.
Micronizer working principle in existing feedstuff industry is as shown in Figure 10: raw material passes through beater disintegrating machine Crushing after (granularity reach in 40 mesh cross 50% or so), which needs high pressure blower ceaselessly discharging when working Air draught at mouthful, material enter pulverizing chamber, material is due to grating disk by unidirectional auger feeder under the action of gravity and air-flow High speed rotation, material is crushed by the shock of tup that is mounted on grating disk, and arrives surrounding so that high speed is spin-off Gear ring on, because of the gap very little of tup and gear ring, because of the variation of the flank of tooth transient change occurs for the air-flow between tup and gear ring. Material in this gap in by alternate stress, further crushed under the repeated action of this power.Through chippy material quilt It enters air-flow under from grating disk to take between inner wall and pod, subsequently into grading room, by the grading wheel of rotation, in wind It is classified under the collective effect of power, gravity and grading wheel centrifugal force, the coarse fodder being separated returns to powder from the inner cavity of pod Broken room is crushed from new, and thin material is inhaled into grading wheel, into discharge chamber, enters separation system from discharge port.
It is simple a little for, micronizer it is most crucial be effect of impact and tup and gear ring using tup and material Between rubbing effect and crush material, wherein occupying an leading position with the effect of impact of tup and the reaction force of gear ring. Variation most crucial between micronizer different model at present is exactly that the quantity of tup is different with the effective area of gear ring, tup Quantity becomes more, and the effective area of gear ring becomes more, and yield is also just corresponding to be promoted.
Existing micronizer has the disadvantage that: (1), the requirement of the raw material grinding particle size of current aquatic feeds increasingly The quality of height, feedstuff is also lower and lower, and the high raw material of fiber content is widely used (such as rice bran, rapeseed meal, cotton dregs), Fiber content is high, and fiber bulk density is small, due to the effect of air-flow in entire crushing process, is not easily accessible the disintegrating area of tup, into And the tup for being not easy pulverized machine is hit, and material is caused to crush indoor circulation, the crushing material efficiency high to crude fiber content Low, material has much room for improvement in the indoor crushing path of crushing;(2), at present in field of feed processing, aquatic feeds crush raw material Granularity crosses 80% or more the vertical shaft type micronizer (such as attached drawing 10) for being all in 80 mesh, and the primary structure of the pulverizer has Auger feeder, expansion chamber, pulverizing chamber, grating disk, tup, wearing plate, gear ring, pod, grading wheel, discharge chamber.It is only outer Layer gear ring, without internal layer gear ring and tup corresponding with internal layer gear ring, the quantity of tup is on the low side, and the effective area of gear ring is on the low side, Overall throughput is low, and energy consumption is high.
Based on this, a kind of more efficient micronizer how is provided, production capacity is improved, reduces energy consumption, be especially applicable in In the high aquatic feeds of crude fiber content, it is a technical problem that technical personnel in the field need to solve at present.
