Above-mentioned is that a kind of concrete structure of the vacuum atomizing powder manufacturing apparatus provided in the present embodiment is described in detail, under
Face will be further described through this equipment with a concrete operating principle, a kind of vacuum atomizing powder provided in this embodiment
One application examples of equipment includes：
Production integrally checks equipment before starting, and connects all cooling waters, checks whether flow everywhere is sufficient, water
Whether joint is secured, and whether there is or not the phenomenons that seeps water, and whether water pipe everywhere has damaged expansion.
By the charge bar clamping processed on feed mechanism, after clamping is secured, starts electric rotating machine, check the rotation of charge bar
Situation, it is ensured that charge bar bottom end rotational case is good, reduces swing to the greatest extent, in order to avoid coil is encountered when charge bar enters induction coil 26
Cause short circuit.
Check whether the door that other are opened closes, if in place, preparation starts to vacuumize locking.
Start mechanical pump, opening give pumping valve, open simultaneously Sample Room, receive powder tank on valve (two Pneumatic butterfly valves are intended to
Open), start vacuum meter, and pay attention to the speed of exhaust, judges that system seal whether there is problem with this.When system vacuum reaches
When to 1000Pa, start lobe pump, opens simultaneously the preceding step valve of diffusion pump while needing high vacuum (if any outfit, and), work as system
When vacuum degree reaches 100Pa, start heating diffusion pumps.If not needing high vacuum or being configured without high vacuum, when system vacuum reaches
When to 7X10-1Pa, you can to stop vacuumizing preparation fusing.If being equipped with diffusion pump and needing high vacuum, diffusion pump is to throw
Enter heating, after forty minutes, closing is all to give pumping valve, opens high threshold, allows diffusion pump to devote oneself to work, when system vacuum reaches for heating
When 7X10-3Pa, stopping vacuumizes preparation fusing.
It is filled with protective gas (argon gas) before melting starts, in system to normal pressure, opens charge bar rotation, adjusts Suo Liao mechanisms,
So that charge bar end is entered the suitable position of coil inside, open the valve on atomization gas cylinder, checks atomization pressure, initially
Gas pressure is not less than 12MPa, starts high pressure positive blower 48, opens melting power supply 22, adjustment fusing power, and observation charge bar melts shape
State opens atomization valve and last row valve when molten drop starts drippage, and adjustment atomizing pressure exists in 4~6MPa, adjustment feed speed
Between 300~750 μm, the matching of power and feed speed is paid attention to, reach lasting fusing and close to the best results of continuous flow.
In atomization process, it should be noted that observation molten state adjusts in time when in order to deviation occur, while paying attention to implementing mist
The atomizing pressure for changing gas adjusts manual modulation valve and is modified, when the pressure of working chamber is less than spray chamber when there is deviation
The pressure-regulating valve of working chamber can be opened to supplement melting chamber pressure, melting chamber pressure is allowed slightly above to be atomized chamber pressure as possible,
It avoids generation powder from backflowing to working chamber to pollute and waste.It notes also the cooling temperature in chamber body, adjusts cylindrical segment 9
With the cooling water temperature of conical section 10 so that temperature between the two is consistent, when if you need to be adjusted, opens in connecting tube 53
Switch valve 54 so that the cooling water of cylindrical segment 9 can be mixed freely with the cooling water of conical section 10, until the two temperature one
It causes.
When charge bar use up or atomization gas be less than 4MPa when, atomization process needs to stop, at this time stop charge bar rotation with
Feeding stops heating power supply 22, and feed mechanism is promoted back into material interior, can be continued to open by atomization gas at this time, favorably
It is delivered to powder-recepting machine structure in atomization powder, reduces and is atomized indoor gas residue.After 2 minutes, atomization gas is closed, closes last row
Valve closes high pressure positive blower 48.
The twice Pneumatic butterfly valve received on powder tank is first closed when receiving powder, if necessary to reduce the chance of powder ingress of air, just
Pneumatic butterfly valve is unloaded together together with powder tank is received, is transferred in glove box (separately matching) and takes powder, do not need such as, can directly unload receipts
Powder tank takes powder, takes and empty receipts powder tank is installed back original position after powder.Carry out experiment production next time.If not testing life for a long time
Production, please be evacuated equipment using mechanical pump, and equipment is stored in vacuum condition.
