Wheel.When work, from the outlet end exhausting of dust collection shell, while being driven by power mechanism and crushing turntable high speed rotation, crushed
Tup on turntable crushes material in such a way that high speed is hit, and material is thrown to gear ring by the high speed rotation of tup,
Material is impacted using high-speed flow, makes material that strong collision and rubbing action occur each other, to reach fine crushing
Purpose；Under wind action, smashed material is upward through fluid dividing cover, then moves along pod inner wall to classifying turbine,
Motor drives classifying turbine to rotate to form centrifugal action, and grinding particle size material up to standard passes through classifying turbine and enters dust collection shell
In vivo, the material of bulky grain is then fallen, and is reentered at tup and is crushed.
Existing classifying turbine using the thin-slab structure being uniformly distributed along the circumference blade, classifying turbine rotation when wind
Hinder larger, the workload of motor is larger, and the structural strength of the blade of flake structure is poor, is easy after prolonged use
It is in the presence of deforming, changes so as to cause the spacing between blade, influence the accuracy of sizing screening, fineness of materials is difficult
With meet demand.
Utility model content

A kind of classified screening device of micronizer solves the classifying turbine of micronizer traditional in current technology using thin plate
The blade of structure, windage when work is big, the big problem of motor power consumption.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of classified screening device of micronizer, including chassis, the center chassis, which is provided with, to be used for and motor
The mounting hole of connection, which is characterized in that on the chassis centered on mounting hole circumferentially uniform intervals be provided with it is several
It is classified bar, the classification bar is stretched out in long rod structure and to the disk on chassis top.Ultramicro grinding described in the utility model
The classified screening device of machine replaces the graded blade of traditional thin-slab structure using the classification bar of long rod structure, and structural strength is high,
It is unlikely to deform, ensures long-acting stable gap, thus ensure the fineness meet demand for the material that screening obtains, point of long rod structure
Windage of the grade bar when rotating with chassis is small, reduces energy consumption, reduces the workload of motor, increases sieving qualification rate, and reduction is returned
Return crushed zone material ratio.
Preferably, the classification bar is cylindrical structure, and structure is simple, intensity is high, easy to process, installation.
Preferably, the classification bar is connected at chassis edge, and the edge uniform intervals on the chassis, which are provided with, to be used
It is easy to loading and unloading in the card slot of connection classification bar, improve maintenance efficiency.
Preferably, the top of the classification bar is connected by being located at the reinforcing ring above chassis, improves structural stability,
It ensures between classification bar that there is long-acting stable gap, ensures the accuracy of sieve fineness.
Preferably in the edge uniform intervals of the reinforcing ring periphery have opened up the card for connecting classification bar
Slot, easy to connect, maintenance efficiency is high.
Preferably, the top of the reinforcing ring is also circumferentially spaced is provided with several sealing blades, ensures and divides
The reliability of grade screening, avoids the material for not meeting fineness requirement from passing through from reinforcing ring top.
Preferably, the sealing blade is along radial thin plate.
Preferably, the sealing blade shifts to install in a circumferential direction with classification bar.
Compared with prior art, the utility model advantage is：
The classified screening device structure of micronizer described in the utility model is simple, compact, reduces classifying screen and chooses to install
