Abstract
A supersonic airflow superfine grinding classifier is a processing device for superfine grinding of materials. It consists of a crushing device and a powder grading device. A plurality of supersonic jet flows are arranged in a crushing chamber of the crushing device, the jet flows carry materials injected into the crushing chamber from a funnel, the materials are collided at the intersection of the jet flows to realize material crushing, the crushed powder enters a grading device and is graded according to the size of powder particles under the action of centrifugal force, the powder meeting the requirements enters a pipeline connected with a collector, and the powder not meeting the requirements is thrown into the crushing chamber for crushing. Its advantages are no abrasion of spray tube, uniform fineness of powder, high pulverizing efficiency and low energy consumption, and is suitable for pulverizing the brittle material with Mohs hardness of 1-10.
Description
What the utility model was related is the ultra tiny pulverizing grader of a kind of supersonic airstream, and it is the process equipment that object is carried out ultra tiny pulverizing.
For satisfying the needs of modern high technology, the ultra tiny pulverizing technology of object processing is developed rapidly.The common mechanical crushing technology can only make the powder granule diameter reach about 45 microns, and ultra tiny pulverizing technology then can make diameter of particle less than 10 microns.The realization of the broken pulverizer of micropowders in the past is by treating that comminuting matter is blended in the compressed air, and material quickens with the supersonic nozzle of airflow passes particular design, is ejected in pulverizing chamber on the metallic target wall, and material is by bump and fragmentation.Then, obtain powder through vertical grading plant again.The weak point of this equipment is object with the air jet pipe of flowing through, and nozzle wall is easy to wear, and object strikes and corrode the target wall makes powder contain jet pipe and target wall material impurity in addition, can not meet the demands; In addition, it is also inhomogeneous that powder enters the selected fineness of powder of vertical grader.
The purpose of this utility model is to provide a kind of supersonic airstream ultra tiny pulverizing grader, and it can realize that jet pipe does not have wearing and tearing, and powder fineness is even, the crush efficiency height.
The purpose of this utility model is to realize like this, with the supersonic nozzle that three or three or more in opposite directions be provided with of compressed air importing through particular design, in pulverizing chamber, form several bursts of supersonic jets of respective number, these jets carry the material that is injected pulverizing chamber by loading hopper, clash into the material fragmentation of realization mutually in jet intersection, powder after the fragmentation enters horizontal grader, under action of centrifugal force, by the granular size classification, in the pipeline that the satisfactory super-fine powder of particle diameter enters with gatherer is connected, the undesirable powder of particle diameter then is thrown into pulverizing chamber and pulverizes.Therefore, powder fineness is high and even, the crush efficiency height.

Below in conjunction with accompanying drawing structure of the present utility model is specified.
Fig. 1, the ultra tiny pulverizing grader of supersonic airstream are made up of reducing mechanism (1) and grading plant (8).Pulverizing chamber (2) in the reducing mechanism (1) is a cylindrical metal tube, and inside is cavity.Be with annular compression air duct (4) outside the bottom of pulverizing chamber (2), be connected with the supersonic nozzle through particular design (3) that is provided with in opposite directions more than three or three thereon, pulverizing chamber (2) inwall is passed in the outlet of these supersonic nozzles.For being mutually 120 ° of distributions, four jet pipes are mutually 90 ° of symmetrical distributions in the layout of annular compression air duct (4) for three jet pipes, and six become 60 ° to distribute or the jet pipe more than six is even cloth.The given embodiment of the utility model adopts four jet pipe distribution forms (as Fig. 2).Also have material inlet (5) at pulverizing chamber (2) sidewall, this charging aperture is located at the nozzle exit top, and Materials hopper (6) injects pulverizing chamber, and injection technique is general prior art, and this paper no longer describes.Material does not directly pass through jet pipe, has avoided wearing and tearing in the jet pipe.At the pulverizing chamber inner chamber, the material that is injected pulverizing chamber by loading hopper (6) is carried in several burst supersonic jets identical with jet pipe quantity, and intersection clashes into mutually at jet, realizes the material fragmentation.Powder after the pulverizing flows to grading plant.
The grading plant of powder (8) is on pulverizing chamber (2) top, and it is made up of stator (10) and rotor (11).The stator of grading plant (or rotor) axis is vertical mutually with the center line of pulverizing chamber (2), is called horizontal grader again.The blade (9) of even cloth some and angle on the circumference at stator in Fig. 3 (10) two ends, there is wheel paddy at rotor (11) two ends, the left end wheel be solid, right-hand member wheel for hollow, some and angle two blades (9) are taken turns paddy with two ends and are linked as an integral body.Motor (12) is installed the upper end with grader, and the rotation of motor is rotated by the rotor (11) that belt and wheel (13) drive grader.
When powder enters into grading plant (8), powder enters the rotor middle cavity by the passage of the blade (9) of rotor, because classification motor (12) drives rotor (11) and does rotation at a high speed, its rotating speed is 3000-30000 rev/min, thereby powder is under the effect of power, by the granular size classification, the powder grain is satisfactory by the hollow pipeline (14) that is connected with the gatherer (not shown) that enters of rotor (11) right-hand member, and undesirable powder is thrown into pulverizing chamber (2) row pulverizing again.Therefore, resulting powder fineness is even.Rotor (11) velocity of rotation is high more, and the powder average grain diameter is also just more little after the classification, even can reach submicron order.
The utility model has the advantage of object without jet pipe, jet pipe does not have wearing and tearing, adopts horizontal grader in addition, powder impurity mixed volume is few, fineness is evenly distributed, the crush efficiency height, the power consumption low. The brittle material that is applicable to Mohs' hardness 1-10 level is pulverized, and is particularly useful for hard abrasive material such as carborundum and impurity content and asks extremely tight spy to expect such as fluorescent material special ceramics etc.
