Electrolytic triple unit module for purifying noble metal

The invention discloses an electrolytic triple unit module for purifying noble metal. The electrolytic triple unit module comprises triple units and a rack, wherein the rack is an integral rack structure capable of containing and installing multiple triple units; the triple units in the integral rack structure are sequentially arranged into two rows on the left side and right side; a circulation loop for connecting the triple units is configured on the integral rack structure; the triple units are vertically arranged on the rack; each triple unit is composed of three cell bodies which are mounted, connected and fixed through an upper connector and a lower connector; an anode and a cathode are contained inside each cell body; a sealing ring, a gland and an upper end cover are sequentially arranged on each upper connector to form a sealed triple unit; an electrolytic solution inlet is formed in each lower connector and the lower connector is connected with an electrolytic solution storage container through the inlet. The electrolytic triple unit module has the characteristics of reasonable and compact structural composition, high use convenience and reliability, convenient installation, wide using scope and greatly reduced investment and production cost.
