Description
Technical field
This utility model relates to 3D and prints Preparation Technique of Powders field, is specifically related to a kind of bulk metal that is prevented from and enters a kind of metal vacuum aerosolizing device slower conical tube of powder collecting bucket.
Background technology
Current gas-atomized powder technique by: melting, be atomized, sieve three operation stages and form.
Melting is to be put in intermediate frequency (or high frequency) stove by the alloy raw material prepared, and is smelted into molten metal, in the process, by methods such as vacuum displacement or addition deoxidizers, reduces the oxygen content in molten metal.
Atomization is to pour in tundish by melted molten metal, and molten metal confluxes into the molten metal fluidization tower of certain diameter with tundish, then through spraying high-pressure gas, molten metal is broken into micron-sized molten drop.Molten metal, after mozzle, enters nebulizer.Nebulizer is a kind of special air jet system, can control bore, pressure and ejection angle during gases at high pressure ejection.Molten metal enters atomization bucket cooling after nebulizer is broken, eventually serves as product and collects.
Use bar as raw-material vacuum aerosolizing device, in fusion process raw material not with any oxide and crucible medium joint, melting atmosphere simultaneously is high-purity argon gas, effectively prevent the bigger metal of activity under high temperature fused state with the reaction of other materials.
Using bar as raw material, after utilizing high frequency induction power supply to be melted metal bar bottom, molten metal liquid stays along inverted cone inclined-plane, bar bottom under gravity and capillary common effect, flows to lower annular nebulizer centre bore.The metal liquid atomization that the high velocity air of ejection will flow down from annular nebulizer.
Easily producing block or sheet metal granule in vacuum aerosolizing device atomization process, these metallic particles are owing to granule is big or screen cloth is caused bigger damage by sharp edges.Sieve aperture damage can cause the particle diameter of minus mesh to produce particle diameter with design and there is discrepancy, causes product quality to reduce, waste product even occurs.
Summary of the invention
The purpose of this utility model is to provide one to be prevented from bulk, sheet metal granule, damages the metal vacuum aerosolizing device slower conical tube of screen cloth.
To achieve these goals, this utility model includes, a turbination slower conical tube, this slower conical tube sidewall and induced duct connection；Fixing the screen cloth of a horizontally set in slower conical tube, the lengthwise position of this screen cloth is prolonged less than the lower end of described induced duct air inlet；Between excircle and the inner surface of slower conical tube of this screen cloth, hermetic seal is connected；The aperture of the sieve aperture of described screen cloth is at 1-10mm；There is a valve slower conical tube bottom.
By arranging the screen cloth of a 1-10mm screen-aperture, it is possible to metallic particles bigger for particle diameter is screened out in advance, it is to avoid bulky grain or sheet-like particle damage screen cloth.Ensure stablizing of undersize material, i.e. metal dust product cut size.
Further, the sidewall of described slower conical tube having material taking mouth, this material taking mouth is with sealing lid, and the lengthwise position of described screen cloth is prolonged less than the lower end of described material taking mouth.Arrange a material taking mouth can oversize on easy cleaning screen cloth, i.e. metallic monolith granule and sheet-like particle.It also is able to according to different production technologies simultaneously, or different raw materials is convenient for changing the screen cloth of different pore size.
Further, also including a vibrating device, this vibrating device is positioned at slower conical tube and screen cloth or fixing with slower conical tube inwall is connected.The metal dust meeting production requirement that increase vibrating device can will attach on screen cloth, metal large particle surface is shaken off, and becomes siftage by sieve aperture, thus reduces yield loss.
Further, also including a vibrating device, this vibrating device is fixed on the outer surface of slower conical tube.The metal dust meeting production requirement that increase vibrating device can will attach on screen cloth, metal large particle surface is shaken off, and becomes siftage by sieve aperture, thus reduces yield loss.
Preferably, described vibrating device is electromagnetic vibrator or ultrasonic vibrator.
Preferably, described screen cloth is that corrosion resistant plate punching is made.
Further, the upper end of screen cloth is fixed with a cylindrical back-up ring.Increase back-up ring and can conveniently collect metallic monolith and sheet-like particle.
Further, described air entraining pipe has a branch road, and this branch road and air blowing ring connection, this air blowing ring is a ring pipe, and the bottom of ring pipe is evenly distributed with gas outlet.Screen cloth is blown by the air-flow utilizing air entraining pipe, it is possible to effectively prevent buildup, and fine grained is enriched with at screen cloth and bulk particle surface.
