Principle is low temperature liquid inert gas to be dropped in into molten bath table completely or directly inert gas is covered in above molten bath, drives molten bath
The air of top, the oxygen content in the overhead gas of molten bath is reduced, so as to avoid alloy liquid oxidation or air-breathing.In smelting equipment work
The largely high temperature inert gas containing metallic fume can be produced when making, gas is entered using the gas purification circulatory system in the prior art
Row purification, purification process suffered blower fan and has been constantly exposed in air, therefore, it is difficult to avoid having ambient atmos by blower fan with it is lazy
Property gas mixing is so as to polluting former inert gas.
The content of the invention
In view of the shortcomings of the prior art, a kind of blower fan suitable for inert gas circulating purification system is now provided and protects dress
Put, prevent ambient atmos from polluting former inert gas, while controllable gas flow rate, stable melting in gas purification cyclic process
Dynamic pressure in equipment.
To achieve these goals, the utility model provides a kind of blower fan suitable for inert gas circulating purification system and protected
Protection unit, the blower fan 1 are placed in vacuum airtight container 2, and the air inlet pipe and escape pipe of blower fan are connected respectively to vacuum tightness appearance
The position that device outer end gas-circulating system, air inlet pipe and escape pipe are connected with vacuum airtight container is respectively connected with sealing device；Institute
State and air ventilation device is also associated with vacuum-tight container, the air ventilation device is before blower fan work by vacuum sealing
Gas in container vacuumize-be filled with the operation of inert gas.
The present apparatus can carry out vacuumize process to vacuum airtight container in advance before blower fan work, blower fan is in vacuum
In environment, and then inert gas is filled with into vacuum airtight container by air ventilation device, the running environment for ensureing blower fan is
Inert gas environment；Then the high temperature inert gas containing metallic fume is purified by the air inlet pipe and escape pipe of blower fan；
The blower fan is in inert gas environment all the time, and the vacuum-tight container position that is connected with pipeline is equipped with sealing device, because
This ensure that the sealing of vacuum-tight container, prevent pollution of the ambient atmos to former inert gas.
Further, the air ventilation device includes the vacuum exhaust pipe being connected on vacuum-tight container and vacuum is mended
Tracheae, vacuum extraction valve is connected on the vacuum exhaust pipe, vacuum gulp valve is connected with the vacuum gas supplementary pipe.
Vacuum extraction valve is opened, vacuumize process is carried out to vacuum-tight container by vacuum suction pipeline；Reach vacuum
After environment, vacuum extraction valve is closed, vacuum gulp valve is opened, inert gas is filled with into vacuum-tight container.
Further, the blower fan is frequency conversion fan.Gas flow rate, stable smelting equipment can be controlled by frequency conversion fan
Interior dynamic pressure, makes metal evaporation tend towards stability, and is advantageous to be precisely controlled to point.
Further, the vacuum exhaust pipe is provided with pressure vacuum gauge.
Further, it is equipped with gas flow control valve on air inlet pipe and escape pipe.
The utility model makes blower fan locate all the time by installing vacuum-tight container additional outside blower fan, and using air ventilation device
In pure atmosphere of inert gases, pollution of the ambient atmos to inert gas during fan operation is effectively prevented, ensures to close
Golden melting protecting effect.
