The utility model relates to a glass melting furnace cooling air current adjusting device of portion is through setting up it is located to dilute the wind export dilute the low reaches of wind entry, dilute the flow direction of diluting wind in the wind wind channel and the flow direction of glass liquid is the same in the runner, moreover, through with dilution wind export still intercommunication sets up a tube -shape main part, be equipped with the follow on the inner wall of tube -shape main part the air inlet of tube -shape main part extends to the screw thread of gas outlet is followed after wind carries out cooling to glass liquid when diluting when diluting wind export discharge, still mixing with the discharge of the interior waste gas of kiln, air current adjusting device, with the help of the tube -shape main part is right dilute the gravitation of taking out that wind applyed, dilute waste gas edge in wind and the kiln screw spiral on the tube -shape main part inner wall rises, is favorable to accelerating gaseous exhaust velocity when keeping the air current balanced, cooling to glass liquid is even, and it is few to form glass surface microdefect.
