Wherein, increase material and manufacture the key that powder body material used is this technology application.
Increasing at present material manufacturing technology material therefor mainly concentrates on: Ti-Ni alloy, iron and steel, pottery, magnaliumThe Rare Metals Materials such as alloy and cobalt, rhenium.
In the past, the powder manufacture method that development comes according to powder metallurgy, can not meet well and increase material manufactureNeed. The high ball-type degree of particle, granularity, size distribution, pine fill ratio, contain oxygen and inclusion content and yield rateAll unstable. Although in existing method, physics powder process method (aerosolization, water atomization, vacuum atomizing, etc.Ion rotation electrode and the atomization of radio frequency plasma torch) and the powder of chemical method manufacture make moderate progress, butCan not meet above-mentioned whole requirement effectively simultaneously. And manufacturing cost is high, powder process type is single, to Gao RongPoint material is difficult to prove effective. Although known radio frequency plasma method effect is more satisfactory, at least need to beProcess on the powder basis of refinement and again manufactured, and can not once directly make alloying powder.
Summary of the invention
The purpose of this utility model is to provide the multi-electrode plasma arc of a kind of metal and ceramic powders and makes continuouslyManufacturing apparatus.
The utility model comprise flash chamber nozzle, plasma arc generator electrode, propeller, fuel rod,Fuel rod fixture, flash chamber nozzle inner walls lining exotic material, the front end both sides of flash chamber nozzle have sprayThe import of mouth water cooling, plasma arc generator electrode is positioned at the middle part of flash chamber nozzle, flash chamber nozzleRear end there is protective gas import, argon gas or other inert protective gas enter from protective gas import,Fuel rod is fixed together by fuel rod fixture and propeller; Propeller is by ring flange, two guidingThick stick, two rhizoid thick stick compositions, have through hole for wearing fuel rod fixture in the middle of ring flange, and ring flange is offeredHave two pilot holes and two screws, two pilot holes are relative, and two screws are relative, and two guiding thick sticks divideChuan Guo two pilot holes, two rhizoid thick sticks are respectively through two screws, and fuel rod fixture and propeller driveFuel rod advances and enters plasma arc generator electrode place.
The utility model is to utilize plasma arc to make fuel rod evaporation atomization, forms particle mist, and fuel rod existsCenter, electric arc around, then utilizes inert gas that the particle mist of atomization is blown into powder dilatation collecting chamber,Cooled and solidified becomes powder subsequently; Described fuel rod is raw metal rod or ceramic raw material rod. The powder makingBody granularity is 0.1～100 μ m.
The beneficial effects of the utility model:
The disposable alloying powder of directly making that can be continuous, put forward production efficiency greatly.

Detailed description of the invention
As depicted in figs. 1 and 2, the utility model comprises flash chamber nozzle 1, plasma arc generator electrode3, propeller 5, fuel rod 6, fuel rod fixture 7, the interior wall liner exotic material of flash chamber nozzle 1, expandsThe front end both sides of room nozzle 1 have nozzle water cooling import 2, and plasma arc generator electrode 3 is positioned at expansionIn the middle part of room nozzle 1, the rear end of flash chamber nozzle 1 has protective gas import 4, argon gas or otherInert protective gas enters from protective gas import 4, and fuel rod 6 is by fuel rod fixture 7 and propeller 5Be fixed together; Propeller 5 is made up of ring flange 51, two guiding thick sticks 52, two rhizoid thick sticks 53,In the middle of ring flange 51, have through hole 511 for wearing fuel rod fixture 7, ring flange 51 offers two and leadsRelative with 513, two pilot holes 512 of two screws to hole 512, two screws 513 are relative, lead for twoPass respectively two screws 513, raw material through two pilot hole 512, two rhizoid thick sticks 53 respectively to thick stick 52Rod clamp 7 and propeller 5 drive fuel rod 6 to advance and enter plasma arc generator electrode 3 places.
Use procedure of the present utility model:
(1), can produce excessive temperature according to plasma arc generator electrode 3, exceed most of required addingWork material boiling point. The fuel rod 6 of rotation being sent to by TRANSIENT HIGH TEMPERATURE electric arc evaporates in dilatation chamber, shapeBecome atomization electricity slurry, form quick-fried spray at flash chamber nozzle 1; Meanwhile, in the flash chamber nozzle 1Under argon gas or helium or mist airflow function, go out dilatation chamber. Again form quick-fried spirt and enter collecting chamber;
(2), in collecting chamber, through fully expanding and the poor effect of strong gas pressure, order about lower atomization in surface tensionParticle is conducive to form ball shape. Owing to being in extraneous relative low temperature (far below metal material freezing point)Under effect, solidify rapidly. Collecting chamber is made up of tubulose spiral cooling device, to obtain the large temperature difference;
(3) have two identical propellers 5, first paragraph propeller 5 walks to stroke 2/3 place, opensSecond segment propeller 5, two ends propeller 5 is worked simultaneously. Next from second, rear metal bar, profitWith friction welding method, two poles are integrally connected;
(4) 5 work of first paragraph propeller are returned to contact switch, and action and so forth, forms continuouslyDuty. Fuel rod 6 is in the work starting stage, front end is processed into pointed, makes the electric arc initial stage stableWork.
(5) between propeller 5 and plasma arc spray nozzle device, sealed by punching block.
(6) pole application diameter 10～30mm, the following silk of 10mm material can be according to institute's rapidoprint needs,Use different size spiral rotating binding clasp. The parameters such as plasma-arc temperature, electrical characteristics, according to need notPowder manufacture need to be used numerical analysis, Material Thermodynamics method to calculate, then relative set.
