Description

Micron disintegrator

The utility model belongs to a kind of size reduction machinery, micron order pulverizer particularly, the decline pulverizing processing of meter level of dry type, wet type, the profit that is applicable to non-metallic materials such as chemical industry, medicine, dyestuff, pigment, agricultural chemicals, cosmetics, grocery trade, pottery.

As everyone knows, current representative micron order size reduction machinery is an airslide disintegrating mill, as: the NQS-25 airslide disintegrating mill that Zhongnan (South Contral) Pharmacentical Machinery Fectory produces, mainly form by spiral air feeder, charging aperture, pulverizing chamber, discharging opening, support; Operation principle or technical process are compressed air (6～8 kilograms per centimeter that come from compressor ²) by the nozzle with pulverizing chamber or certain angle form high velocity air to material suspended body through scissors, collision and grinding, reach the pulverizing purpose, little venthole on the collet circumference of finished product micro mist in pulverizing chamber is together taken out of through discharging opening by gas and is entered in the bag, its production capacity is 20～25 kilograms/hour, feed size≤3～4 millimeter, accounting for more than 75% of smashing fineness≤5 micron, the largest particles≤50 micron, this machine is pulverized in the industry at micron order and has been made very big contribution, but also there is certain problem, 1, user's reflection in use, the blowback phenomenon takes place owing to the venthole of collet is often stopped up by dust, directly influence operator's physical and mental health, need often cleaning maintenance, also influence operating efficiency; 2, this machine can only be processed siccative, so in using certain limitation is arranged; 3, this machine need be equipped with air compressor machine, so it is big to take working space; 4, working ability relative deficiency.

The purpose of this utility model be overcome above-mentioned weak point and provide that a kind of volume is little, efficient is high, relative working ability is big and micron pulverizer that all can process siccative, wet feed and material moistening.

The purpose of this utility model is achieved in that

Micron pulverizer described in the utility model, form by charging aperture, pulverizing chamber, discharging opening, electric transmission machanism and support, the coarse crushing part is formed by feeding mouth 12 and the coarse crushing device 1 that is fixed in main shaft 4 upper ends in the top that it is characterized in that pulverizing chamber, and the broken part of fine powder is formed by cylindrical shell 10 and one group of roll 2 that has special spiral grooves in the bottom.

Pulverizer described in the utility model is characterized in that the outside of cylindrical shell 10 has the cooling chamber of chuck 3 formations to cool off.

The characteristics of micron pulverizer described in the utility model are that compact conformation, production capacity are big, and maximum 300 kilograms/hour, 10 microns of finish fineness ∠ all can process for siccative, wet feed, material moistening or sheet material.Pulverization principle is that material enters in the pulverization cylinder body after the coarse crushing of coarse crushing device in charging aperture, the roll that one group of band particular channel is arranged in the cylindrical shell, and it is minimum with the gap of barrel, roll is made the air-flow that high speed rotating produces rotation under the gear drive of main shaft, in the future be filled in the groove of roll and the gap of roll and barrel as for the material after the coarse crushing, material continues to be turned round roll crown and the grinding of pulverizing barrel like this, the shearing of revolution roll lead angle and barrel, the impulsive force of moving about between the revolution roll, material itself in the roll spiral grooves reach and barrel between comprehensive function such as extrusion friction and reach the pulverizing purpose, afterwards generated heat because of cylindrical shell rubs, carry out liquid cools so set up chuck formation cooling chamber in the cylindrical shell outside.

Below in conjunction with accompanying drawing the utility model is described in further detail;

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the intention of executing of the utility model coarse crushing device;

Fig. 3 is the vertical view of the utility model meal device;

Fig. 4 is the schematic diagram of the utility model roll;

Above Fig. 1～Fig. 4 also is a most preferred embodiment of the present utility model;

Sequence number is represented among the figure: meal device 1, roll 2, chuck 3, main shaft 4, gear train assembly 5, discharging opening 6, receiving hopper 7, electric transmission machanism 8, support 9, cylindrical shell 10, material channel 11, charging aperture 12.

Fig. 1 shows the overall structure of pulverizer, the upper end of pulverizer is a taper charging aperture 12, be positioned at the coarse crushing device 1 coaxial upper end of being fixed in main shaft 4 of charging aperture 12, the below that is positioned at charging aperture 12 is a cylindrical shell 10, the outside of cylindrical shell 10 has chuck 3 to constitute cooling chamber so that the water flowing cooling, be positioned at roll 2 that three of cylindrical shell 10 have an identical thread groove on the uniform location-plate that is positioned cylindrical shell 10 two ends of main shaft 4, roll 2 is minimum with the barrel gap of cylindrical shell 10, gear train assembly 5 is all formed by the gear on travelling gear and the main shaft 4 in the lower end of roll 2, the lower end of cylindrical shell 10 is fixed as one by location-plate and support 9, between the receiving hopper 7 of between charging aperture 12 and the cylindrical shell 10 and cylindrical shell 10 and its underpart the material channel 11 that communicates is arranged, there is discharging opening 6 side of receiving hopper 7, its lower end also has blanking port temporary cover closure, the lower end of main shaft 4 is formed electric transmission machanism 8 by belt wheel by belt and motor, belt wheel preferably adopts the polywedge bet wheel, by changing rotating speed and the fineness of different belt wheels to this machine of adjustment; Fig. 2 or Fig. 3 show the dnockout rod that coarse crushing device 1 has three layers of four symmetry;
