One scrapes moisture film anti-smog deviceTechnical field
The present invention relates to a kind of technical field of mechanical equipment, scrape moisture film anti-smog device particularly to one.
Background technology
Owing to, in mechanical part manufacture process, the motion of its high speed liquid stream or high velocity air, atomizer inevitably causes the entrance of outside air；Although also having and adopting inert gas shielding, but owing to tundish is not effectively protected, thus causing Powder Oxidation.In prior art, owing to inert gas shielding arranges improper, often cause and gag somebody.
Prior art has the disadvantage that tundish needs heating, superposes generation hole with nozzle, causes outside air to enter；Nozzle inert gas shielding arranges unreasonable, causes outside air to enter；Air enters, and causes mechanical part oxidized；Atomizer is owing to without air pressure balance measure, air-flow or liquid flow movement velocity variations, near nozzle, pressure produces change, thus causing phenomenon of gaging somebody.
The structural design of this technology is unreasonable, and packaging air tightness is low, safety is low, production cost is high, production efficiency is low and service life is short.
Summary of the invention
In order to overcome above-mentioned technical problem, the invention provides one and scrape moisture film anti-smog device.
To achieve these goals, one of the present invention scrapes moisture film anti-smog device, and its reasonable in design, air-tightness are high, safety is higher, long service life, production efficiency are high.
The technical solution adopted in the present invention is to the invention provides one to scrape moisture film anti-smog device, including: 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 more than protective gas air inlet pipe.
By the above-mentioned description to present configuration it can be seen that adopt such structure, in described body, it is 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 sealing with atomizer, 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 more than protective gas air inlet pipe; atomization air pressure under different condition realizes balance, it is ensured that atomizer is possible to prevent mechanical part oxidized, and the safety making device is 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, one provided by the present invention scrapes that moisture film anti-smog device has reasonable in design, air-tightness is high, safety is higher, long service life, production efficiency advantages of higher.
