Description
Technical field
The invention belongs to field of powder engineering, be specifically related to the solid material reducing mechanism.
Background technology
Water-jet technology is a new technology that grows up gradually the sixties in 20th century, by water jet exploitation originally, progressively develop into fields such as water jet cleaning, cutting, to the mid-80, Missouri, USA-roller (Missour-Rilla) university's rock mechanics and blasting technique research center, at first utilize high-pressure water jet to carry out timber, waste paper pulp-making, treatment of Municipal Solid Waste, and the pulverizing of coal and mineral test, thereby begun the research of high-pressure water jet crushing technology, and paid more and more attention.High-pressure water jet is pulverized the positive paid more and more attention of this new technology, has viewpoint to think, high-pressure water jet is pulverized with ultrasonic wave and pulverized and hot crushing technology, may be an innovative technology in the 21 century comminution engineering.
Though the water jet crushing technology has been showed good prospects for application, this Study on Technology also progressively turns to commercial development to use from experiment.But, it is very few that present domestic external enwergy is applied to industrial water jet reducing mechanism, the development of water jet crushing technology is restricted, its main cause be existing water jet reducing mechanism that is that all right technically is ripe, and the water jet granularity control of pulverizing and the exploitation of new and effective water jet reducing mechanism relatively lag behind.Typical case with the water jet crushing technology uses---and it is example that mica is pulverized, the pulverizing of insulating paper mica raw material at present, the water jet reducing mechanism that domestic enterprise generally uses is also very original, has influenced the exploitation of high-grade mica insulation paper, becomes the technical bottleneck that the sector development needs to be resolved hurrily.
Existing water jet reducing mechanism is divided into three kinds of forms both at home and abroad: directly the water jet current grind (Straight Water Jet); Preceding mixed material jet current mills (DIA Jet); Back mixed material jet current mills (Abrasive Entrained WaterJet).Wherein:
1. the water jet double-disk pulverizer of U.S. Missouri-Rilla university development (directly water jet current mill) is used for the pulverizing of coal.Its operation principle is: upper and lower disk is respectively by motor-driven, and can independently adjust the relative velocity of disk.When coal feeds the crusher chamber that two disks constitute by one and the coaxial mounted feed pipe of top disc, centrifugal force gets rid of coal cinder to the disc surfaces of rotating outwardly, directly inject gap between two disks by the water jet of the nozzle on motor-driven swivel head ejection, impact the coal that is subjected to Mechanical Crushing between two disks.Passed through the slit ejaculation of grading after pulverizing less than the coal particle of granularity requirements, bulky grain is then further pulverized in crushing chamber.
The rotating jet grinding machine of the 2. Italian DIMM of University of Cagliari laboratory development (directly water jet current mill) is used for the pulverizing of coal.Its operation principle is: have one to be with the spray gun of two nozzles in rotation above the circular small opening that the annular wall of crusher chamber and conical centre form.The material that adds is fallen material after the bullet bottom enters crusher chamber and forces fragmentation by small opening, again be positioned at following shock plate and carry out impact comminution again.Another kind of directly water fluid jet grind device for coal similarly is: water jet through swivel joint by the coal grain in the nozzle directive container, container is closed, the coal grain was constantly impacted by water jet in the extremely short time, and under turbulent flow and the effect of cavitation erosion effect, the coal grain is pulverized.
1. above-mentioned and 2. two kinds of water jet reducing mechanisms, owing to adopted motor-driven rotational structure in various degree, make reducing mechanism too complicated, and bring wearing and tearing and problems such as water under high pressure sealing, its water jet impact strength is limited, being used to be easy to the pulverizing of the coal of cleavage, also is the initial stage structure of water fluid jet grind.
3. preceding mixed material jet current mill, the ultra-fine water jet reducing mechanism of delaminating of German AKW company and Denmark Lang Ni company (APVRASNNIEA/S) is arranged, its operation principle is: water under high pressure is divided into two the tunnel, wherein one the tunnel enter the fluidization chamber of high pressure storage tank bottom through choke valve, make the local fluidization of jar interior material, obtain the initial velocity that flows simultaneously.Another road water under high pressure enters mixing chamber, and fully mix with material slurry from the fluidization chamber, mixed slurries are transported to nozzle and are accelerated, and the material in the feed liquid is subjected to the rubbing action of nozzle wall and partly is sheared pulverizing, and further pulverize to the target body bump.
4. fine homogenizing device (preceding mixed material jet current mill), its operation principle is: make particle slurry ultra-fine or that delaminate be among the high pressure in fluid bed and produce homogenising by high-pressure installation pressurization, when slurry arrives tiny nozzle, extrude, be injected on the target body with the speed of hundreds of meters of per seconds.Because the mutual fricting shearing of particle slurry when extruding, slurry is extruded the cavitation erosion effect that pressure reduction suddenly in back is produced in addition, and particle slurry is injected in the powerful impulsive force that target body produces, make by ultra-fine particle of delaminating along cleavage between crystal layer or fault location explosion, thereby realize ultra-fine purpose of delaminating.
3. above-mentioned and 4. two kinds of ultra-fine water jet reducing mechanisms of delaminating (preceding mixed material jet current mill), though obtain higher energy efficiency, but complex structure, cost height, can not work continuously, each charging is limited, productivity ratio is low, and nozzle stops up and wearing and tearing easily, so be applicable to the pulverizing soft, and less material of raw material granularity.
5. back mixed material water fluid jet grind, its operation principle is: water under high pressure is converted into high-speed water jet through nozzle, and produces high vacuum in mixing chamber, the granule materials in the feed arrangement is sucked mixing chamber and sneaks in the water jet.In so-called collimator, water jet rock breaking becomes a large amount of water droplets, forms the PARALLEL FLOW section, and continuous and particle bumps, and the speed of granule materials is fully improved, and the collision of the particle of high-speed motion and target body causes pulverizing then.
6. self-vibration formula water fluid jet grind (back mixed material jet current mill), its operation principle is: solid jet is changed into the impact type jet of pressure fluctuation, and the high-speed water jet that water under high pressure forms through top nozzle is injected the vibration chamber, and material is sucked.Because the collar vortex that self-vibration forms stream has aggravated cavitation.When particle is sucked into the vibration chamber, also air has been brought into the vibration chamber and promoted cavitation.Jet and mixing of materials after down nozzle enter amplifier, formed the pulse cavitating jet of gas, solid, liquid three-phase.From the material particles of amplifier ejection bump mutually pulverizing chamber, and under the synergy of the erosion effect of the water hammer effect of pulsing jet, cavitation and water wedge effect, material is able to be pulverized.
5. above-mentioned and 6. hybrid jet mill structure is simple after two kinds, operation is put just, can work continuously, treating capacity is big, but also exist material particles and high-speed water jet undercompounding to some extent, the not high and problems such as classification and granularity control of energy efficiency.
