Abstract
A vacuum sprayer for preparing metal powder features that in a vacuum environment, inertial gas in used to atomize the molten metal to obtain spherical metal particles.
Description
Affiliated technical field
The present invention relates to a kind of high energy vacuum gas dusting device, especially the material of metal species can be entered fusing and be atomized into powdered granule rapidly.
Background technology
At present, known metal powder all is to operate by the physics or the method for chemistry, and the process relative complex becomes more simple for making technology, the invention provides a kind of metal powder vacuum gas dusting device, can address the above problem.
Summary of the invention
Technical scheme of the present invention is: the present invention is made up of melting chamber and spray chamber, and has vavuum pump, turns over a pot motor, melting pot, and induction furnace, seal bar, catheter, manual magnetic valve, receiving flask constitutes.Superincumbent melting chamber is provided with melting pot and induction jar, with vavuum pump gas in the cabin is extracted out, in melting pot, melt earlier, the molten metal that will melt is again poured in the induction jar, reach temperature required after, mention seal bar, spray metal liquid downwards, simultaneously by spray into inert gas to molten metal second vacuum chamber spray chamber advance in atomize, form required metallic particles.
The invention has the beneficial effects as follows, can be simple to operate, obtain the ball-type product, and can feed other gas as required, obtain other metallic compound.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
This figure is a schematic diagram of the present invention.
1. melting chambers among the figure, 2. induction furnace, 3. crucible, 4. seal bar, 5. drain is led, 6. vavuum pump, 7, inert gas conduit, 8. interface, 9. spray chamber, 10. taper is not held, 11. manual magnetic valves, 12. receiving flask, 13. magnetic valves, 14. turn over a pot motor, 15. melting furnace, 16. melting chamber hatch doors, 17. aeroseal passages.
The specific embodiment
In the drawings, open the hatch door (16) of melting chamber, add required metal material to melting furnace (15), close hatch door (16) then, open the air in vavuum pump (6) the extraction melting chamber, begin the metal fusing of heating, after metal is melted, by turning over a pot motor (13) metal liquid of melting furnace (15) lining is injected into the induction furnace (2) that is provided with crucible (3) again, at this moment the seal bar (4) of induction furnace (2) lining is upwards mentioned, molten metal goes out downwards along catheter (5), locate to feed inert gas at the melting chamber (1) and the interface inert gas conduit (7) of spray chamber (9) simultaneously, molten metal is just atomized in spray chamber (9) lining, forms small metal particles, and the metallic particles of this device fabrication is spherical.After the completion of processing, cool off again, when temperature reach not can oxidation condition the time, open the magnetic valve (13) of external ventilation, break vacuum, open manual magnetic valve (11) again and take off and send out collection bottle (12), promptly obtain finished product after sieving.
