Cathode plates and conductive bars between slots

Abstract

The invention discloses a negative plate and a conducting bar between baths. The non-conducting end of the negative plate is provided with a non-conducting end hanger, the conducting end of the negative plate is provided with a conducting end hanger, the non-conducting end hanger is directly welded to the negative plate, and the conducting end hanger and the plate face of the negative plate are formed integrally. The conducting bar between baths is provided with a plurality of grooves, and the grooves are used for the conducting end hanger to be embedded therein. The problems that conductivity between polar plates and a conducting rod is poor in the silver electrolysis process, and current efficiency is low can be solved. By increasing the conducting area and wrapping the non-conducting end hanger with an insulating sheath, contact resistance is reduced to avoid short-circuiting, the heat-emitting problem of the conducting rod is solved, power consumption is reduced, and the current efficiency of silver electrolysis is improved; the conducting area between the negative plate and the conducting bar between baths is increased easily, the negative plate and a positive plate are placed more orderly, the conducting efficiency is higher, and current density indexing between the polar plates is more uniform.

Description

technical field [0001] The invention relates to the technical field of electrolytic plating, in particular to a cathode plate and an inter-tank conductive bar for silver electrolytic refining. Background technique [0002] At present, most of the cathode plates used in silver electrolysis at home and abroad are stainless steel plates and titanium plates, and the cathode conductive rods are titanium rods, and the conductive rods and the cathode plates are connected by welding or rivets, and the cathode conductive rods and the cathode plates are usually connected by two pieces. The relatively narrow titanium plate leads to limited conductivity, and the conductive row between the slots is a thin silver plate. The actual electrolysis process contains a large amount of acid mist, so that the conductive connection is often corroded, and the electrolyte dripped during the operation also often drops on the conductive connection, causing scaling and heating on the conductive contact ...
