Concrete meaning.
Embodiment 1
With reference to shown in Fig. 1 to Fig. 3, the utility model provides the device that a kind of vacuum arc prepares metal dust, the dress
Put and receive powder unit 3, vacuum pump group 4 and the charging for storing the first wire and the second wire including atomization unit 1, first
Unit 2, one end of charging unit 2 connect provided with vacuum pump group 4, the other end with the top of atomization unit 1 or sidepiece, and feed unit
2 are used to be connected, be used for source of the gas and power supply respectively to the first wire of conveying of atomization unit 1 and the second wire, atomization unit 1
The first wire and the second wire are atomized, the first receipts powder unit 3 connects with the bottom of atomization unit 1.
In use, first, the first wire and the second wire are connected by atomization unit 1 with the positive and negative electrode of power supply,
And the top of the first wire and the second wire is stretched into atomization unit 1 and keep contact；Then, vacuum pump group is started
4, until the pressure in charging unit 2 reaches designated value；Then, source of the gas is connected, gas is constantly sprayed into atomization unit 1；Connect
Get off, connect the power supply of atomization unit 1, start to be atomized the first wire and the second wire, and start charging unit 2 simultaneously,
Because now the first wire and the second wire are connected by the positive and negative electrode of atomization unit 1 and power supply respectively, that is to say, that this
When the first wire and the second metal opposite polarity, the wire meeting at the contact point of the first wire and the second wire
Arc melting is constantly played in atomization unit 1 and forms molten metal, and the gas that molten metal can be injected into atomization unit 1 dispels into
Multiple small spherical droplets, spherical droplets are flown in atomization unit 1, are shunk, cooled down by liquid surface tension force, is frozen into
Metal dust, and eventually fall directly under gravity in the first receipts powder unit 3, it is at the same time, single with atomization is stretched into
The continuous fusing of the first wire and the second wire in member 1, charging unit 2 can feed the first gold medal to atomization unit 1 in real time
Belong to silk and the second wire；Finally, after running specified time, source of the gas and power supply is closed, removes the first receipts powder unit 3.
It follows that when preparing metal dust using the device, the first wire and the second wire are only needed in contact point
Arc melting is played to form molten metal, molten metal is dispelled into small drop, whole mistake in atomization unit 1 by gas injection again
Molten metal does not contact with miscellaneous part in journey, therefore substantially increases the purity and recovery rate of metal dust；Further, since first
Wire and the second wire only produce electric arc in contact point, and starting the arc fusion range is small, and the first wire in the unit 2 that feeds
Vacuum environment is constantly in the second wire so as to further ensure the stability of metal powder constituent.

Second receives powder housing 5-1 top connection, and the second top for receiving powder housing 5-1 is provided with the second valve 5-2, powder is received in bottom with second
Tank 5-3 is connected.
Because the second receipts powder housing 5-1 is connected by connecting pipe 5-4 with atomization unit 1, as the second valve 5-2 of opening
When, the portion gas that source of the gas is sprayed into atomization unit 1 can be discharged by the second valve 5-2, so as to what is formed in atomization unit 1
The less spherical droplets of size or metal dust can enter second with air-flow and receive in powder housing 5-1, and finally make in self gravitation
Fallen into under the wall constraint with the second receipts powder housing 5-1 in the second receipts powder tank 5-3.Thus, powder unit is received by setting second
5, so that it may which the spherical droplets formed in atomization unit 1 or metal dust are subjected to categorised collection, specifically, larger chi according to size
Very little spherical droplets or metal dust can not be entered second with the air-flow for flowing through the second valve 5-2 and be received powder housing 5- due to heavier
1, it can only be fallen under self gravitation effect in the first receipts powder unit 3；And the spherical droplets of reduced size or metal dust due to
