ABSTRACT:
A waste metal extraction apparatus is disclosed which includes a tank (1) having a plurality of oppositely disposed arcuate baffles (14) disposed on the sidewalls. The baffles are placed in an offsetting relation in order to direct the flow of a fluid through the cell in essentially a serpentine fashion. The arcuate baffles facilitate maintaining a maximum velocity through the turning radius of the fluid passing therethrough to prevent a solids buildup. In addition, the tank is placed at an angle of at least 6 degrees downwardly sloped ind the direction of flow. The tank bottom (6) includes a plurality of sockets (20) sized to engage a plurality of cathode supports (21) placed therein, with each support including a mating end (22) for mating with the socket. Each post includes a slot (23) extending substantially therethrough for accepting a cathode (13) therein. A conductive metal fork (31) is disposed over the post having legs (32) which extend the length of the cathode, providing uniform electrical properties across the surface of the cathode thereby providing for optimum, uniform metal removal. The tank further includes a sludge gate (36) at the outlet end thereof with the sludge gate provided for removing any solids which settle as the waste stream follows the serpetine path provided by the arcuate baffles, the sludge gate removing a concentrated solids-containing stream which may be filtered and recycled to the tank inlet. Utilizing the combination of flow modifying baffles, a sloped bottom and enhanced electrical contacting means provides for use of electrolytic cells for removing heavy metals from streams containing about 1-15% solids without requiring frequent down time for tank cleaning.
