Abstract
An apparatus for cleaning and sealing the peripheral knife edge of a coke oven door has a vertical mast which is positioned adjacent one edge of a door suitably supported in vertical position on a door rack. A treatment carriage in the form a horizontal arm is mounted for vertical reciprocation along the mast. Spray heads are mounted on an endless conveyor chain looped around turning point sprockets at opposite ends of the treatment carriage. The diameter of the turning point sprockets and the distance therebetween are related to the curvature of the corners of the door and the width of the door so that as the drive chain traverses the upper part of its endless run the spray heads can spray a path corresponding to the profile of the top edge of the door and the curved corners at opposite ends thereof. Correspondingly, when the chain proceeds along the lower part of its run, the spray heads can transverse a path corresponding to the profile of the lower edge of the door and the curved corners at its opposite ends. A reciprocal drive is provided for moving the treatment carriage up and down along the mast. When the treatment carriage moves up the mast an inner edge of the door is tre…
