Material mouth (sample tap), while body side is additionally provided with a vacuum port with cock；Ground discharges with overhead condensation in the connection
Mouth connection, outer grinding port is connected with ground in the reception of receiving flask upper end.
It is preferred that, wherein the interior ground and outer grinding port that are connected are mutually matched, prevent gas leakage.
It is preferred that, the internal diameter of all interior grounds is 24mm in described device, and the external diameter of all outer grinding ports is 24mm.
It is preferred that, the interior outer grinding port attachment means length is 180mm, and external diameter is 8mm, and the lower end mouth of pipe stretches out outer grinding port
25mm。
It is preferred that, discharging opening internal diameter on the receiving flask is 6mm, positioned at away from bottom of bottle 20mm at, and Way out vertically to
Under.
It is preferred that, the vacuum port internal diameter on the receiving flask is 6mm, and length is 70mm, is in 35 ° with horizontal direction.
The receiving flask vacuum port, overhead condenser vacuum port connection after be connected with vavuum pump, it is ensured that tower top pressure and
The consistent of bottle pressure is collected, tower top discharging is more stablized smooth；Cock and receiving flask in the middle part of the interior outer grinding port attachment means
Vacuum port cock is simultaneously closed off before receiving flask discharging so that the pressure in the bottle and atmospheric pressure one when receiving flask discharging opening is opened
Cause, realize normal discharging, there is no any influence to the pressure of whole rectification system while discharging.
