Replace spent anodes or cathodes used in electrolytic cells as scheduled.
What does a Cell Changer do?
Replaces spent anodes or cathodes used in electrolytic cells, according to replacement schedule, using handtools and power tools: Disconnects electrical and pipe connections and removes retaining bolts to free cells, using wrenches. Removes cell top and cathode assembly, using tension handles, prybars, and hoist. Measures thickness of cathode blade and length of anode to determine remaining usable life, using ruler, and inspects anode for deterioration. Adjusts anode and cathode spacing, using handtools. Records cell and cathode number and condition of anode and cathode. Scrapes and washes putty and dirt from cell assembly, using hand scraper and steam or water hose, or cleans cathode bars and cell bottom with power grinder and acid. Cleans and smooths electrical connections, using emery cloth. Transfers defective units to cell repair room and obtains replacement parts, using cart or crane. Positions cell bottom, anode, cathode, and cell top in place, using hoist. Bolts assemblies together, replaces sight glasses, funnels, and percolator pipes, and secures electrical connections to bus bar, using handtools. Seals joints with putty, mortar, and asbestos, using putty extruder and knife. Turns valves to start brine flow. Records new parts used and date of change. May repair cells [CELL REPAIRER]. When draining and cleaning mercury electrolytic cells, replacing mercury, and timing rate of flow of mercury to ensure efficient operation, may be designated Mercury-Cell Cleaner.
