The utility model discloses a
mixed gas distribution device which comprises a bottom plate, a base fixedly installed at the top of the bottom plate, a mixing box fixedly installed at the top of the base, an
argon box fixedly installed at the top of the bottom plate, a first sucking pump fixedly installed at the top of the
argon box, and a first gas suction
pipe fixedly installed at the suction end of the first sucking pump. The end, away from the first sucking pump, of the first air suction
pipe extends into the
argon box, and a first air feeding
pipe is fixedly installed at the discharging end of the first sucking pump. The device is reasonable in design and good in practicability,
chlorine and argon which are added into the mixing box can be fully stirred, the
gas mixing efficiency is improved, the spiral gas conveying hose is used for enabling the
mixed gas in conveying to continuously rotate, the
mixed gas is prevented from being layered in the conveying process, the
gas mixing effect is improved, and the service life of the device is prolonged. And the air pressure value in the mixing box can be increased by controlling the
piston plate to move downwards, so that
gas mixing is accelerated, and the mixed gas can be conveniently output for use.
