Description
Technical field
The present invention relates to a kind of atomising device, particularly a kind of aerodynamic atomization spray nozzle device that has ring cartridge type ultrasonic radiator that is used for metal powder process.
Background technology
Vacuum atomizing powder process is smelting metal or metal alloy under vacuum condition; under the condition of gas shield; metal liquid flows out, by high-pressure inert gas stream the metal liquid atomizing is broken into a large amount of tiny drops by nozzle through insulation crucible, water conservancy diversion mouth; tiny drop is frozen into sphere or inferior spheric granules awing; because drop is tiny and the heat exchange condition is good; the condensation rate of drop generally can reach 100～10000K/s, than the high several magnitude of the cooling of ingot casting.Therefore the composition of alloy is even, organizes tinyly, and the alloy material made from it does not have gross segregation, excellent performance.Vacuum atomizing powder process can prepare metal and the alloy powder thereof that great majority can not adopt in air and the water atomization method is made, and secondly, because setting rate has overcome segregation phenomena soon, can produce the spherical or inferior spherical powder of many specific alloys.At last, adopt suitable technological parameter, can make powder size reach the scope of a specified requirement.The all available atomization production of nearly all metal that is melted, especially suitable for producing alloy powder.Vacuum atomizing powder process method production efficiency height, and be easy to enlarge commercial scale and be subjected to extremely wide industrial and use.
Vacuum atomizing powder process method is a coefficient complex process of numerous parameters, and the pressure of the granularity of vacuum atomizing powder, shape and crystalline structure and atomization process parameter such as melt-flow diameter, nozzle arrangements, ejection medium, flow velocity etc. are closely related.Particularly the aerodynamic atomization nozzle arrangements of vacuum atomizing is one of technical problem of most critical.
Summary of the invention
Purpose of the present invention is just in order to provide a kind of aerodynamic atomization spray nozzle device that has ring cartridge type ultrasonic radiator.This aerodynamic atomization spray nozzle device can make the ejection atomizing of molten metal more reasonable, and atomizing is even, and powder by atomization speed is fast, efficient is high, cooling is rapid, can work continuously, the particle diameter of metal atomization powder is little, and the output capacity height is very good metal atomization fuel pulverizing plant.
Purpose of the present invention can realize by following technique measures:
Aerodynamic atomization spray nozzle device of the present invention comprises nozzle body, be arranged on the vertical through hole of nozzle body center position, be installed in the woven hose in the vertical through hole, stay the chamber around the gases at high pressure that vertical through hole is arranged in the nozzle body, and the ring cartridge type ultrasonic radiator that is arranged on gases at high pressure below in the chamber around vertical through hole; The side that described gases at high pressure are stayed the chamber is connected with external high pressure argon gas or nitrogen source of the gas by through hole and connecting line, the bottom surface of staying the chamber at gases at high pressure is provided with the air flue that extends and be communicated with the cavity of ring cartridge type ultrasonic radiator to side-lower, be provided with in the bottom surface of ring cartridge type ultrasonic radiator cavity to side-lower extend by several nozzle rings that constitutes with the nozzle bore of uniform arrangement mode setting, described nozzle bore all is provided with in the crossing skew back mode of the following extended line of its axis and woven hose axis, and the cross section minor axis dead in line of the annular chamber of the axis of described nozzle bore and ring cartridge type ultrasonic radiator.
Operation principle of the present invention and beneficial effect are as follows:
When carrying out vacuum atomizing powder process, the gas of high pressure argon gas or nitrogen and so on enters gases at high pressure by pipeline and stays the chamber, and enter ring cartridge type ultrasonic radiator via air flue, nozzle ring from ring cartridge type ultrasonic radiator bottom sprays then, the air-flow of nozzle ring ejection concentrates on the metal fluid column that flows out from woven hose, thereby reaches the purpose that liquid is atomized.This aerodynamic atomization spray nozzle device that has ring cartridge type ultrasonic radiator, the high pressure gas very high speed that blows out, can make the ejection atomizing of molten metal more reasonable, atomizing evenly, powder by atomization speed is fast, efficient is high, cooling is rapid, can work continuously, the particle diameter of metal atomization powder is little, the output capacity height.
