Abstract

Abstract An apparatus for removing zinc deposited on zinc electrolysis cathodes utilizes a high pressure stream of water applied to the cathodes progressively between the line of demarcation between the aluminum sheet and deposited zinc; including a frame supporting a series of parallel high pressure water lines to apply the streams of water progressively over the surfaces of the cathodes which, in turn are supported in spaced relation on a carriage which is movable to expose successive cathodes to the water streams.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 189 words
An apparatus for removing the zinc deposited on zinc electrolysis cathodes, characterized in that it comprises: a stationary support having at the top a vertically movable frame adapted to serve as support means for a number of parallel highpressure water lines; and at least one moving cathode carriage running preferably on rails and adapted to move thereon as far as a place below the top moving frame, the moving carriage having at the top on both sides separators adapted to maintain the cathodes vertical and equidistant from one another, each high-pressure water line having at least one nozzle so directed that the fanshaped stream of water is incident upon the boundary line between the aluminium sheet and the zinc deposited thereon in a manner adapted to dis-engage the zinc, the moving carriage being open at the bottom so that the separated zinc sheets can drop through, said cathode carriage has on both sides pushers which are displaceably mounted on such carriages through the agency of guide rods and which are adapted to bear on the vertical edges of the cathodes when the carriage moves below the top moving frame.
Claim 2
Independent Claim 189 words
An apparatus for removing the zinc deposited on zinc electrolysis cathodes, characterized in that it comprises: a stationary support having at the top a vertically movable frame adapted to serve as support means for a number of parallel highpressure water lines; and at least one moving cathode carriage running preferably on rails and adapted to move thereon as far as a place below the top moving frame, the moving carriage having at the top on both sides separators adapted to maintain the cathodes vertical and equidistant from one another, each high-pressure water line having at least one nozzle so directed that the fanshaped stream of water is incident upon the boundary line between the aluminium sheet and the zinc deposited thereon in a manner adapted to dis-engage the zinc, the moving carriage being open at the bottom so that the separated zinc sheets can drop through, said cathode carriage has on both sides pushers which are displaceably mounted on such carriages through the agency of guide rods and which are adapted to bear on the vertical edges of the cathodes when the carriage moves below the top moving frame.
Claim 3
Dependent Claim 34 words
An apparatus according to claim 1, characterized in that the stationary support is a portal on which the top moving frame is suspended with the interposition of vertical guide rods and a hydraulic cylinder.
Claim 4
Dependent Claim 45 words
An apparatus according to claim 1, characterized in that the portal has on at least one of its side uprights a runner which is rigidly secured to the upright and on which the outer end of the guide rods of the respective pushers can move.
