Abstract
PURPOSE: To keep window glass free from staining for a long time with simple construction by fitting a wiper cloth to a shutter which opens and closes a peeping window, and blowing a purging gas into the clearance between a window member and the shutter.
CONSTITUTION: A window member 3 and a shutter 4 by leaving a slight distance therefrom are provided in a peeling window casing 2 fitted to the top part of a blast furnace. The shutter 4 is actuated by the operation of a cylinder 5 contained in a supporting frame 13 provided on the extension line above the casing 2. A wiper cloth 6 is fitted to this shutter 4 to remove the stains on the inner side of the member 3 during opening or closing. The member 3 is fixed by way of O-rings 7, 8 for sealing and a purging gas such as gaseous nitrogen is blown into the clearance between the shutter 4 and the member 3 through pipings 11a, 11b. In this state, the shutter 4 is taken up to separate the frame 13 from the casing 2 and the wiper cloth 6 is exchanged.
