Automatic recovery device for hollow glass production and processing waste gas

The invention relates to the technical field of glass production waste gas treatment, and particularly discloses a hollow glass production and processing waste gas automatic recovery device which comprises a fixed seat, a base is fixedly mounted on one side of the top of the fixed seat, a lifting rail is fixedly mounted on the top of the base, and a lifting mechanism is slidably connected into the lifting rail; a second motor is used for driving a sliding block to adjust the air suction cover to move up and down, the height of the air suction cover is conveniently adjusted, meanwhile, a first motor is used for driving a first gear and a gear ring to be in meshing transmission, and a mounting ring can be driven to rotate on the outer surface of an annular base. The gear ring drives the mounting ring on the outer surface of the annular seat to rotate, namely the mounting ring assists in driving the air suction cover to rotate, the air suction cover can be adjusted to rotate to rotate around the machining positi
