Said invention is developed on the basis of high-speed pin-disk type high-shearing homogenizing machine (Chinese practical utility ZL 99227293.9), Said invention not only is applicable of ultramicropulverization of wet pulverization of liquid-liquid, liquid-powder and liquid-solid materials, but also is applicable to ultramicropulveri-zation of dry materials to micrometer-level and nanometer-level in the fields of metal, non-metal, food, chemical and pharmaceutical industry, etc.

Description

Shearing strongly, strong strike, abundant hole triple role start at the same time and surpass pulverizing structure machine

Superfine communication technique is a high-tech industry of rising, and has caused the attention and the concern of scientific and technological circle, academia, educational circles, medical science the world of medicine, business circles.Superfine communication technique is used and is progressed into every field such as food, medicine, plastics, electronics, pigment, coating, cosmetics, textile, metallic ore, nonmetallic ore, papermaking, health products from military project, heavy industry, light industry, chemical industry, becomes the effective high-tech approach of seeking economic development and improving product specification and economic value added.

Stressed in mechanical movement form difference according to the crushing process material, mechanical crushing equipment has ball mill, Raymond mill, eddy mill, ultrasonic wave pulverizer and supersonic jet mill (dry pulverization process) high pressure homogenizer, colloid mill, bucket formula high shearing mixing emulsor and sand mill etc.Because therefore the crushing process more complicated does not also set up complete crushing mechanism until now.And the field of pulverizing ubiquity two big world difficult problems: the one, and the effective energy utilization rate that is used to pulverize is extremely low, pulverizing energy consumption height, for example the capacity usage ratio of large-size ball mill only is 0.6%, even the capacity usage ratio of supersonic jet mill only is 2%, two also, beans, pulp, vegetable fibers are difficult to ultramicro grinding.

My high speed pin disc type high-shear homogenizing machine of succeeding in developing in 1998 (patent No.: ZL99227293.9) obtained the good performance of enterprises and economic results in society since putting on market, good breakthrough has all been arranged to solving above two big world difficult problems.The one, than high pressure homogenizer energy-conservation 2/3rds, the 2nd, but soak 8 hours full soya bean fiber through high homogenizer ultramicro grinding to 0.-2 μ m account for overall 90% or more (see on December 29th, 98 and on January 28th, 99 Wuxi Light Industry Univ.'s Foodstuffs Academy related detection report), fruit meat need not be squeezed the juice like this, can be directly with pulp (apple, orange, coconut etc.) after the ultramicro grinding, make full fiber apple beverage, high-grade full fiber health drink such as orange beverage, also can be directly with tealeaves, pumpkin, glossy ganoderma, pollen etc. are made the high-grade nutrient and healthcare products of full fiber, and the economic benefit of its health care and generation can't be estimated.The full fiber fruit drink of estimating China necessarily can contend with and fashionable world beverage market with the Coca-Cola and the Pepsi Cola of the U.S..

Physical mechanical ultramicro grinding effect more complicated has shearing, extruding, strike cavitation to come comminuting matter.Micronizers such as existing high pressure homogenizer or supersonic jet mill are the main body pulverization to hit collision all, and other shearing, cavitation are secondary.Therefore, effectively the size reduction energy utilization rate is lower, and energy consumption is inevitable just high.Want to improve capacity usage ratio to 5% to 8% and the ultramicro grinding fiber at the 0.1-5 micron, just must look for another way, break the normal procedure adopt shear strongly, hit effectively, the abundant ultramicro grinding structure or the mechanism that start at the same time of hole triple role, realize doing, the micron order and the nanoscale ultramicro grinding of wet stock.

Shown in figure one, fuselage 1, cover 2, rotating ring I-IV, encircle the pulverizing structure that I-IV and part levels such as main shaft 14 and Moving plate 11 become triple role to start at the same time surely.Rotating ring I-IV is contained on Moving plate 11 and the main shaft with hex screw, with 2930-7000 rev/min of rotation at a high speed, encircles I-IV surely and is contained on the cover motionless.After material enters rotating ring I inner chamber from feeding mechanism, rotating ring with the abundant cavitation that strong shearing is done and inside and outside rotating ring differential is caused between high blow speed and the moving fixed ring by ultramicro grinding layer by layer.Therefore, strong hit, shear strongly and fully the hole start at the same time and make dried shape material be able to ultramicro grinding to micron order and nanoscale, its effective size reduction energy utilization rate improves greatly.Than supersonic jet mill energy-conservation 2/3rds.Ultra-fine grinding to each industry of national economy will produce immeasurable microcosmic and macro-economic rersults.

Rotating ring IV and the material that encircles surely between the IV are constantly entered the Ultrafine Classifier classification by pulverizing, are crushed to the micro mist that requires fineness and transport system selected (figure three) along the wind of compositions such as cyclone separator, airlock, superfine powder filter.This is a kind of form of this patent aspect dry grinding.If fuselage 1 and cover 2 are changed over vertical, will encircle III simultaneously surely and encircle IV surely and change over structure discharge method shown in figure two, not only be applicable to dry grinding, but also be applicable to the ultramicro grinding that wet-milling is broken that it is broken up to the wet-milling of 30-40% being specially adapted to solid content.Rotating ring 9 ' is interior curved tooth and 3-Φ A or A outlet of 6-Φ, and material is by the part ultramicro grinding that shuts up, and this moment, cavitation was stronger.

The overall structure that the curved tooth of this patent rotating ring and multiple tooth and multilayer are pulverized decide cyclic group formed shearing edge of circle and multiple tooth overall structure (shown in figure one and figure two) and the reasonable clearance between the moving fixed ring and is all guaranteed strong shearing, hits and ultramicro grinding structure that abundant hole triple role starts at the same time effectively.

This patent both had been applicable to dry grinding, was applicable to broken (comprising homogenizer, Mixingemulsificationmachine, colloid mill etc.) of wet-milling and various micronizer again.

Shown in figure one and figure two: the 1-fuselage; 1 ＇-vertical fuselage; The 2-cover; 3-rotating ring I; 4-encircles I surely; 5-rotating ring II; 6-encircles II surely; 7-rotating ring III; 8-encircles III surely; 8 ＇-Ding encircles III; 9-rotating ring IV; 9 ＇-rotating ring IV; 10-decides IV; The 11-Moving plate; 10 ＇-price fixing; 12-tooth mother; 13-holds ; The 14-main shaft; 15-off-load seat;
