Description
Technical field
The utility model relates to a kind of field of powder metallurgy, particularly the hermetically sealed atomization tundish of a kind of atomized powder and attemperator.
Background technology
As everyone knows, existing atomized powder production process tundish generally adopts field fabrication, atomization process atomizer superposes with tundish and places, tundish is different from atomizer material, pottery or graphite crucible etc. the material that general tundish adopts fire clay to make, and nozzle adopts metal material to make.Two kinds of different materials, tundish and nozzle are when heating and thermal insulation, and temperature 400 ~ 1200 degree, even higher, because the coefficient of expansion is different, tundish and Expansion sealing can produce gap, seal failure.
Due to the motion of atomization process high velocity liquid stream or high velocity air, atomizer inevitably causes entering of outside air.Adopt inert gas shielding although also have, because tundish does not carry out available protecting, thus cause Powder Oxidation.In prior art, because inert gas shielding arranges improper, often cause and gag somebody.
Prior art has the following disadvantages: tundish needs heating, superposes and produces hole, cause outside air to enter with nozzle; Nozzle inert gas shielding arranges unreasonable, causes outside air to enter.Air enters, and causes atomization process Powder Oxidation.Atomizer is due to without air pressure balance measure, and air-flow or liquid flow movement velocity variations, near nozzle, pressure changes, thus causes phenomenon of gaging somebody.
The structural design of this technology is unreasonable, and packaging air tightness is low, security is low, production cost is high, production efficiency is low and service life is short.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide the hermetically sealed atomization tundish of a kind of atomized powder and attemperator, and its reasonable in design, air-tightness are high, security is higher, long service life, production efficiency are high.
The technical scheme that the utility model adopts is that the utility model provides the hermetically sealed atomization tundish of a kind of atomized powder and attemperator, comprise: body, it is characterized in that: in described body, be provided with tundish, described tundish bottom is provided with atomizer and tundish filter tip, described atomizer is provided with two groups or many group sealed nozzle pads, side, described tundish bottom two is provided with nozzle air inlet pipe and protective gas air inlet pipe, described organism bottom is provided with atomizing cup, described atomizing cup top is provided with atomizing cup steam vent, described body inward flange is provided with heater, described body upper is provided with centring hole.
As preferably, described tundish cross section is trapezoidal.
As preferably, described nozzle air inlet pipe bore is greater than protective gas air inlet pipe.
From the above-mentioned description to the utility model structure, adopt such structure, in described body, be provided with tundish, described tundish bottom is provided with atomizer and tundish filter tip, described tundish cross section is trapezoidal, and described body upper is provided with centring hole, makes structural design more reasonable; Described atomizer is provided with two groups or many group sealed nozzle pads, and tundish superposes with atomizer and seals, and tundish also carries out inert gas shielding, makes air-tightness in encapsulation process better; Side, described tundish bottom two is provided with nozzle air inlet pipe and protective gas air inlet pipe, described nozzle air inlet pipe bore is greater than protective gas air inlet pipe, atomization air pressure under different condition realizes balance, ensure that the smooth atomization of atomizer, makes the security of device higher; Described organism bottom is provided with atomizing cup, and described atomizing cup top is provided with atomizing cup steam vent, and described body inward flange is provided with heater, makes the longer service life of device.
As can be seen here, a kind of atomized powder hermetically sealed atomization tundish provided by the utility model and attemperator has reasonable in design, air-tightness is high, security is higher, long service life, production efficiency advantages of higher.
