Description
Technical field
The utility model relates to technical field of powder engineering, particularly a kind of environment-friendly and energy-efficient eddy mill that various materials is carried out to ultra-fine grinding.This environment-friendly and energy-efficient eddy mill is not only for leading-edge fields such as military project, space flight, and extensively applied in different industries, as chemical industry, electronics, machinery, metallurgical building materials, plastics, rubber, food, medicine, papermaking, daily use chemicals, the energy, the relevant industries such as super-fine processing of environmental protection, nonmetallic materials.
Background technology
Ultrafine powder technology is called cross-centennial new and high technology by domestic and international scientific and technological circle.
Along with developing rapidly of science and technology, the research of superfine material and nano material application, has broad application prospects, and to promoting industrial technology progress, has extremely important effect.Generally by 10 microns, with thin powder, be called superfine powder, 1 micron is called superfine material with thin powder, and 0.1 micron is called nano material with thin powder.
Production equipment and the technology of super-fine material mainly contain at present: mechanical impact crusher, airslide disintegrating mill and oscillating mill etc.The general character of these technical equipment is to break the problems such as mill Limit Grain Size can only reach 5 microns of left and right, and the suitability for industrialized production that reach super-fine material also has certain technology and technology difficulty, and ubiquity yields poorly, energy consumption is high, and environmental-protecting performance is poor, powder purity is lower.
Airslide disintegrating mill is current more advanced ultra-fine equipment in the world, mainly contains following several types: 1. flat air flow crusher; 2. circulating airslide disintegrating mill; 3. pair spray formula airslide disintegrating mill; 4. target formula airslide disintegrating mill; 5. fluidized bed airflow pulverizer etc.; The jet powder that has BJ University of Aeronautics & Astronautics and the classifying equipoment (model JFC-30) of current key popularized project, working media is compressed air, gas consumption 15m
3/ min, power 170kW, feed size 0.5mm, product grading 2-8 micron, fineness of materials d50 can only reach 2-40 micron, output 30kg/ hour.Also have Beijing San Huan powder High-tech company of Chinese Academy of Sciences fluidized bed jet mill, fineness of materials d50 can only reach 2-40 micron.According to another < < ultra-fine grinding classification technique > > (China Light Industry Press, calendar year 2001 publish) bibliographical information: there are the following problems for airslide disintegrating mill: 1, energy consumption is large, production efficiency is low.2, output is less, is generally no more than 100kg/h, and major part is less than 50kg/h.3, preparation superfine powder is also more difficult.4, airslide disintegrating mill complex structure, expensive.For above problem, airflow pulverization is currently not advanced.
Mechanical impact crusher and vibration medium grinder are a kind of more traditional mechanical grinding equipment, and mechanical type is many.Its mechanism is to utilize the direct drive medium of mechanical energy to move comminuting matter, and crushing effect is also very low, and difficulty reaches powder purity requirement, and it is poor that powder fineness is compared airflow milling.For example vibrating medium grinder and effectively pulverize power and be about 0.3%, is heat and loss and be about 98% Conversion of Energy.Airslide disintegrating mill is to utilize up to velocity of sound or subsonic air-flow to penetrate energy comminuting matter.And mechanical energy is converted to velocity of sound air motion energy, and need to consume a large amount of energy, the former is larger for its energy consumption work ratio.
The technology of preparing of superfine material (submicron order), the current report of also not finding to have this respect both at home and abroad, it was reported that superfine material is a kind of bottleneck material being limited between super-fine material and nano material, does not also have technology of preparing to produce at present.
The technology of preparing of super nano material at present report is many, mainly uses chemical method preparation, has solid phase method, liquid phase method, vapor phase method and plasma method, laser method etc.Separately have report to discuss, the nano material that adopts chemical method to produce, tends to change the physical property of material itself, does not reach the result of use of nano material, and agglomeration traits is difficult to solve, and production efficiency is low, processing cost costliness.Can only produce in laboratory at present, cannot realize suitability for industrialized production.
For required ultrafine powder and the nano-powder of energy High-efficient Production, China Patent Publication No. CN1929925B discloses a kind of high energy turbulence mill and two negative pressure worm gear thereof, the two negative pressure worm gears of its critical component comprise that Ye Panhe is arranged on a plurality of blades of these two sides of leaf dish, wherein this blade in each side of this leaf dish along circumferential uniform distribution, and rotation direction is identical, the blade that is positioned at this side of leaf dish is wrong next towards each other along week with the blade that is positioned at this leaf dish another side; This pair of negative pressure worm gear also has a plurality of impact tooth plates, each impacts tooth plate and comprises that an installation portion is connected the operate portions of this installation portion with one, at the top of this operate portions, be formed with paired impact teeth, two impact teeth in every impact tooth with tooth top relatively away from mode tilt.When this pair of negative pressure worm gear is in mill chamber during High Rotation Speed, can produce high-strength eddy current and turbulent flow mill chamber is inner, thereby form Dual-Phrase Distribution of Gas olid, material is under the effect of high turbulence, mutually there is strong autogenous grinding, produce strong head-on collision and shear force simultaneously, thereby material is pulverized effectively.The high energy turbulence mill product grading forming with this pair of negative pressure worm gear reaches 0.1-0.9 μ m.
The mechanism of this pair of negative pressure worm gear turbulization is: because bi-negative pressure turbine is to impact tooth plate by left and right throwing arc hypsokinesis blade and swallow-tail form to be assembled, blade is scalene cone and has formed whirlpool shape near one end of sharf simultaneously, two eddy current when High Rotation Speed, have been formed, two eddy current have produced again two negative pressure, the generation of two negative pressure has formed again high-strength centrifugal force, when pulverized solid material is in high turbulence factory in mill chamber, just formed Dual-Phrase Distribution of Gas olid, the turbulence energy obtaining from worm gear, by effect of inertia, by Maelstrom, pass to step by step little whirlpool, material produces strong shock in this turbulent motion, autogenous grinding, shear force, thereby material is pulverized effectively, in addition, stator guiding gear ring produces the guiding shearing force to material in mill chamber, powder is in zigzag turbulent motion region, produce each other strong autogenous grinding, accelerate effective refinement of material.But this pair of negative pressure worm gear needs higher rotating speed, therefore very high to the requirement of motor and blade, impact tooth plate intensity, energy consumption is also higher simultaneously.Also more complicated of this pair of negative pressure worm gear arrangement in addition.
