The weak point that existing vertical crusher exists is: first, the energy consumption of pulverizer is high, efficiency is low: because the fineness that requires to pulverize is lower, therefore in order to increase the kinetic energy of shock, just must increase the rotating speed of cutter head, make more than the linear velocity of tup reaches 100 metre per second (m/s)s, cause more than the power consumption of finished product powder reaches 50 degree.The second, size and the area of tup are less, and material is subject to the impacting of tup and gear ring, cutter can be less, cause crush efficiency low.The the 3rd: because material is subject to tup and gear ring shock shear action, its wearing and tearing to tup and gear ring are strengthened and under the effect of high velocity air, are passed in the process of baffle liner and classifying turbine by the fines after pulverizing, larger equally to the wearing and tearing of baffle liner and classifying turbine, general every three months will be changed once, and these parts prices are higher, the consumptive material of material per ton is high.
For another example: China Patent Publication No. CN201774941U discloses a kind of grinding system, it utilizes existing horizontal hammer crusher, improves output.Its concrete system comprises former material screen, pulverizer without sieve, expansion chamber, screw conveyor, elevator, Powder screen and powder collecting cabin, expansion chamber is positioned at the below of pulverizer, the discharging opening of pulverizer is connected to one end of expansion chamber, the other end of expansion chamber is connected with the air inlet of pulse dust collector, the air outlet of pulse dust collector is connected with the import of blower fan, screw conveyor is positioned at the bottom of expansion chamber, the discharge end of screw conveyor is connected with elevator, former material screen oversize outlet is the charging aperture toward pulverizer without sieve by device for cleaning pipeline, the upper end discharging opening of elevator is connected with Powder screen charging aperture, the outlet of Powder screen screenings is connected with the entrance of powder collecting cabin, the outlet of Powder screen oversize is the charging aperture toward pulverizer without sieve by device for cleaning pipeline.This system, by the combination of a series of screenings, conveying equipment, realizes without sieve and pulverizes object.Pulverizer without sieve is wherein top charging, bottom discharging, and it overcomes the deficiency of existing vertical crusher, but its grindability is general.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, provides a kind of without sieve micronizer, requires that output is high, cost is low, good crushing effect.
For achieving the above object, the utility model is by the following technical solutions: a kind of without sieve micronizer, it includes main shaft, end plate, gear ring, rotor and main motor, gear ring forms pulverizing chamber with the pulverizer end plate that is fixed in gear ring both sides, main shaft two ends through end plate are fixed by main shaft bearing, main motor is connected with main shaft one end, the rotor that is positioned at pulverizing chamber is fixed on main shaft, pulverizing chamber top is provided with pulverizer discharging opening, wherein: be also provided with scroll feeder, skewed slot and blast pipe, the discharging opening of scroll feeder is communicated with skewed slot one end, the skewed slot other end stretches in described pulverizing chamber, blast pipe one end is communicated with described pulverizing chamber, and the blast pipe other end is communicated with described pulverizer space outerpace.
Further, described blast pipe one end is communicated with pulverizing chamber lower space.
Further, be also provided with air uniform plate, air uniform plate is provided with hole, and air uniform plate is positioned at the exit, blast pipe one end being communicated with described pulverizing chamber.
Adopt the beneficial effect after technique scheme:
1, pulverizer without sieve, coordinates by the rotor containing hammer leaf and the gear ring outside rotor, effectively avoids the formation of material circulation layer in crushing process, improves output, reduces use cost; The design of blast pipe, makes the surrounding air outside pulverizer can enter pulverizing chamber, improves crushing effect.
2, blast pipe one end is communicated with pulverizing chamber lower space, and the air that newly fills into pulverizing chamber can, with reflux type through whole pulverizing chamber, further improve crushing effect.Air uniform plate, makes the air-distribution that fills into more even, improves crushing effect.
