    • An apparatus for the electrolytic recovery of metals from liquid solutions containing recoverable metal values. The apparatus comprises a housing containing a tubular cathode concentrically disposed about and radially spaced from an elongated anode for defining a solution-containing volume there-between. An elongated tubular baffle means having a plurality of thoroughgoing perforations through the side wall thereof and along the longitudinal length thereof is disposed about a substantial length of the anode and is in registry with the inlet to a solution pumping means located within the housing that is utilized for circulating the solution in a helical flow pattern within the housing volume. As the solution is circulated by the pumping means, a substantial volume of the solution passes into the baffle means through its open end and through the perforations so that the presence of the baffle means inhibits the formation of vortices in the circulating solution and provides for uniform solution distribution within the volume to assure the presence of metal at the cathode even during relatively low concentrations of the metal in the solution. The housing is supported on a base containing the drive means for the pumping means in such a manner that it can be readily removed from the base for facilitating the removal of the collected metal from the cathode.
    • 一种用于从含有可回收金属值的液体溶液中回收金属的设备。 该装置包括壳体,该壳体包含与细长阳极围绕并径向间隔开的同心地设置的管状阴极,用于在其间限定含有溶液的体积。 具有穿过其侧壁并沿着其纵向长度的多个彻底穿孔的细长管状挡板装置围绕阳极的大部分长度设置并且与位于壳体内的溶液泵送装置的入口对准,所述溶液泵送装置被利用 以使溶液在壳体体积内以螺旋形流动方式循环。 当溶液通过泵送装置循环时,大量体积的溶液通过其开口端穿过挡板装置并穿过穿孔,使得挡板装置的存在阻止在循环溶液中形成涡流并提供均匀的 体积内的溶液分布,以确保金属在阴极处的存在,即使在溶液中金属的相对低浓度下。 壳体被支撑在底座上,该底座上包含用于泵送装置的驱动装置,使得其可以容易地从基座移除,以便于从阴极去除所收集的金属。
