High-precision box-type annealing furnace for optical glass production

The invention discloses a high-precision box-type annealing furnace for optical glass production, and particularly relates to the technical field of glass production.The annealing furnace comprises an annealing furnace body, the lower surface of the annealing furnace body is fixedly connected with the upper surfaces of a plurality of supporting legs, and the opposite faces of every two corresponding supporting legs are fixedly connected with the left side face and the right side face of a temperature control box through fixing rods correspondingly; and the upper surface of the temperature control box is fixedly connected with the lower surface of a water tank. Through the arrangement of the first guide pipe, the connecting shell, the rotating blades, the transmission gear, the toothed plate and the sealing plate, when the sealing plate seals the discharging head on one side, the discharging head on the other side is in a communicated state, so that gas is discharged outwards, the process is repeated, and the
