The utility model belongs to a kind of ultra-fine grinding equipment, and specifically a kind of hypersonic air flow that utilizes by by the mutual high velocity impact of crushed material, is realized the equipment of material powder.
The superfine communication technique of material is the novel technique that grew up in recent years.Modern industry require a lot of solid-phase materials with Powdered as the raw material of industry, they have superfine particle diameter, strict size distribution, certain crystalline form, very low impurity content, as in goods such as chemical industry, medicine, agricultural chemicals, filler, powdery polymer, coating, senior abrasive material, solid lubrication, senior electroceramics, graphite, mica, metal dust, cosmetics, food, health products, require only several microns of powder average grain diameters, have in addition below 1 micron.But general commonly used size reduction machinery but is difficult to produce the product below several microns even 1 micron, and product purity, size distribution, screening all can run into unsurmountable difficulty.So the air-flow crushing technology has vast potential for future development, and the position of in powder industry, occupying, be more and more important.
It is a kind of to spray formula ultra micro jet mill grinding machine that the purpose of this utility model is to provide, and has automatic charging, the adjustment of variable air rate negative pressure, low noise and other advantages.
To spray formula ultra micro air-flow crushing process be: the compressed air (working media or energy carrier) after purifying quickens in the supersonic speed nozzle, produce supersonic speed (M=2.5-3) air-flow, simultaneously, because high velocity air is to the negative pressure ejector action of nozzle wall, the material inhalation nozzle that need are pulverized quickens, mixes, make material quicken to obtain enough kinetic energy, the material particles that is scattered in the interior turbulent flow of pulverizing chamber collides mutually, thereby reaches the purpose of pulverizing.
Expecting the powder below several microns even 1 micron, is can not be getable with common sieve method; Material after crushed except that closing a large amount of qualified powder, also contains many defective powders, and these powders obviously are underproof as the raw material of industrial department, and in addition, from concerning this body structure of spray formula airslide disintegrating mill, it does not have from classifying capability; So this airflow comminution system must outer distribution flow point level equipment.
The air current classifying principle mainly contains gravity, inertia, centrifugal three kinds of forms.This equipment adopts wind-force centrifugal classification principle.Mixed airflow from bottom to top is scattered in the clasfficiator inner chamber, produces centrifugal force field under the turning effort of impeller high speed.Because material particles has the branch of thickness, so the centrifugal force that produces, centripetal force are also different; Coarse granule centrifugal force is bigger, shifts to the limit wall and falls, and returns pulverizer and pulverizes; The big micro mist (fine grained) of fine grained centripetal force is shifted to rotor center, under suction function, by making finished product after cyclone collector collection, the discharge.
Below with reference to embodiment description of drawings ins and outs:
Fig. 1 is the utility model structural representation;
Fig. 2 is the nozzle structure chart.
The utility model is made up of airslide disintegrating mill (1), centrifugal classifying (2), cyclone collector (3), sack cleaner (4), exhaust blower (5), control cabinet (7).Frame (6) is assembled into one airslide disintegrating mill (1), centrifugal classifying (2), cyclone collector (3).Provide the crushing and classification machine required working media-purification of compressed air by the purification of compressed air system, it is characterized in that:
(1) described airslide disintegrating mill adopts spray formula ultra micro air-flow is pulverized, and quickening the nozzle that compressed air forms supersonic flow is fabricated structure, by nozzle body (10) with chew tail (9) two parts and form;
(2) in the described realization system vacuum magnitude to change the exhaust blower of adjusting (5) be the variable air rate exhaust blower;
(3) airslide disintegrating mill (1) and exhaust blower (5) are all formed closed separate cavities by the buckle-type blimp;
(4) charging aperture (8) of airslide disintegrating mill (1) is connected to the variable-ratio feeding auger discharge end of feed bin.
Because the difference of pulverized material, physical parameter, with its powder particle diameter, the isoparametric difference of even particle size distribution, operation factors during work is different, and operation is selected rationally because of speed, and entire equipment reaches optimum state, then crushing effect is good, otherwise effect is with undesirable, and it is more easy that the utility model is devoted to operation, the easier selection of operation factors realizes better crushing effect.
Pulverizer, exhaust blower covering sound arrester make work noise reduce to 85dB (A) by 108dB (A); Working media speedup nozzle changes fabricated structure into by overall structure, except that the functional requirement that keeps nozzle, improves manufacturability, saves processing charges, and guarantees the homogeneity between each nozzle.
Changing hand stock is automatic continuous feeding
Feeding quantity is a very important parameters of one of pulverizer operate as normal, promptly according to differences such as the kind of material, granularity, content, the output of crushing rear material, granularity requirements on request, correct selected raw materials amount, just can reach the ideal effect of expection, for this reason we to change hand stock be automatic continuous feeding, both alleviated operator's manual labor, also stable assurance output improves crush efficiency.
This equipment adopts centrifugal, the stage arrangement of wind-force, and equipment is universal, blade wheel structure, diameter are fixed, so, for different materials or for the different same material of granularity requirements, the rotating speed of its impeller is distinguishing, in order to reach desirable grading effect, the rotating speed of impeller is selected to be very important, promptly is an important process parameter.This equipment impeller is infinitely variable speeds, and maximum speed reaches 10000rPm, has improved grading effect greatly beyond doubt, has strengthened the adaptability of equipment, and general effect is better.
Adopt the variable air rate exhaust blower
This equipment is to work under the negative pressure in closed system, because varying by comminuting matter, pulverize the difference that the back particle diameter requires, in order to reach desirable effect, should correctly select the negative pressure value parameter, adopting the variable air rate exhaust blower undoubtedly, is one to improve greatly, because of the decisive factor of vacuum magnitude in the system is an exhaust blower.
