Motivation blade industry has broad application prospects.3D printing, or increasing material manufacturing is as a kind of fast rapid-result of rising in recent years
Type technique, using successively powdering, laser or electron beam melt the mode being molded, and realize the finishing shaping of precise part, and
And the defects of avoiding the shrinkage cavity shrinkage porosity of casting process appearance, turn into a kind of emerging material manufacturing process.
Powder used in 3D printing at present, typically simultaneously used into ingot casting, subsequent secondary smelting by vacuum pouring after melting
The mode of atomization legal system powder is obtained, and in current atomization method, after typically being flowed directly out using metal bath, melt is blown
Realize atomization.The more advanced technique in part is atomized after then melt is thrown away using centrifugal process, and during being thrown away using centrifugation,
Inventor it has been investigated that, what melt threw away gas in rear atomization process blows speed, angle, and the direction of liquid stream is to the effect of atomization
Have an impact with the granularity of powder after atomization, but current centrifuging process is after continuous centrifugal goes out liquid by the way of blowing, because
And make obtained powder particles skewness.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of atomization preparing apparatus of nickel aluminium powder.
Complete technical scheme of the invention includes：

There is collecting chamber, cyclone separator and ultrasonic vibrating screen are provided with collecting chamber.
The present invention is relative to the advantages of prior art：By centrifugal nozzle, alloy melt is got rid of with centrifugal
Go out, add the speed thrown away, thus bigger crushing force can be produced when being contacted with atomization air flow, improve crushing effect,
Simultaneously using the controlled valve of pulsed, melt is just thrown away at face atomization air flow direction, be in contact, maintain broken
When angle uniformity, improve the uniformity coefficient of powder, at the same according to the density of nickel alumin(i)um alloy, speed of melting, liquid supply speed,
The features such as centrifugal rotational speed, the optimization design of liquid storage bag and atomizer size is carried out for it, relative to titanium aluminium, due to nickel aluminium
Do not have high reactivity, it is possible to deposited the long period in liquid storage stove, thus use the liquid storage stove of large-size,
Allow melting once that relatively large-tonnage powder is made, simultaneously because it than great, the atomization for devising large-size is sprayed
Mouth, linear velocity is bigger when throwing away it, and atomizing effect is more preferable, more efficient.
