Description

Energy-saving and environment-protecting cathode for electrolytic manganese

Technical field

The utility model relates to electrodeposition, electrolysis process technical field, is specifically related to a kind of cathode for electrolytic manganese.

Background technology

At present, in electrolytic manganese production technology, its negative electrode is generally arranged current conducting rod, plain carbon stool bolt, stainless steel cathode pole plate with fine copper and is made.Cathode plate adopts the plain carbon stool bolt to be connected with current conducting rod, the appearance of current conducting rod reaches and the contact site of cathode plate is easily caused corrosion by electrolyte contamination in actual production process, cause that (the new cathode resistor that uses in existing the production is about 90 micro-ohms in the contact resistance increase, the cathode resistor that used 3 months is about 190 micro-ohms), need the rust cleaning of artificial irregularly dismounting bolt to re-assembly negative electrode, the plain carbon stool bolt is easier to be corroded by electrolyte contamination, and cause loosening even be shed to electrolyzer and product is shed in the final product when peeling off, composition (Fe in the carbon steel bolt, C, S, P, Si) entering electrolytic solution pollutes, reduced the purity (Fe of electrolytic manganese, C, S, P, Si belongs to impurity in electrolytic manganese, the electrolytic manganese purity that this old negative electrode of life-time service will cause producing descends, can make the about 0.002-0.005% of electrolytic manganese purity decline), current conducting rod is made with fine copper row, physical strength is low, can only need increase fine copper row's size by exceeding conduction, satisfy physical strength, increased the consumption of copper, the manufacturing cost of negative electrode is strengthened, current conducting rod is generally 8mm with the width that public busbar contacts, contact area is little, physical strength is low, yielding in the use, cause the loose contact of current conducting rod and public busbar easily, increase contact resistance, thereby increased energy consumption, reduced electrolytic manganese output, needed every day manually repeatedly to search, the phenomenon of getting rid of current conducting rod and public busbar loose contact, the grooving of negative electrode and operation are all by manual, labor strength is big, and efficient is low.

Summary of the invention

Technical problem to be solved in the utility model is: the problem that exists at above-mentioned prior art, and provide a kind of prevent and reduce pollute that burn into good environmental protection, conductivity are good, steady quality, physical strength height, routine maintenance are simple and easy, the energy-saving and environment-protecting cathode for electrolytic manganese that reduces production costs, realize easily mechanized operation.

The technical solution adopted in the utility model is: this energy-saving and environment-protecting cathode for electrolytic manganese, comprise cathode plate, current conducting rod, and current conducting rod comprises the outer and conductive copper core of current conducting rod again; The current conducting rod skin is a homogeneous material with cathode plate, and both are fixedly connected with welding process; Coated with conductive copper core in the current conducting rod skin, the current conducting rod position that contacts with public busbar has breach, draws the conductive copper core, and the conductive copper core contacts with public busbar.

In the technique scheme, the current conducting rod skin also is fixedly connected with handle, and handle and current conducting rod skin, cathode plate are homogeneous material, and the three connects with the welding fixed form.

In the technique scheme, seal with sealing material between current conducting rod skin and the conductive copper core.

In the technique scheme, cathode plate, current conducting rod skin and handle are stainless steel or titanium material simultaneously, and the conductive copper core is the fine copper material, and sealing material is a macromolecular material.

In the technique scheme, the current conducting rod skin is a closure casing, one end is a square body, the stage casing and the other end are " worker " font body or " worker " font body and square body interval combination, " worker " font body of the stage casing and the other end or " worker " font body and square body coat " worker " font conductive copper core in the combination at interval, and its gap seals with sealing material.

Unusual effect of the present utility model is: the conductive copper core only exposes the part that contacts with public busbar, rest part all is sealed and coated in the current conducting rod and with current conducting rod is outer and closely contacts, the part of the sealed coating of conductive copper core can not corroded by electrolyte contamination, current conducting rod and pole plate are welded to connect and make electrolytic solution avoid the pollution that the corrosion carbon steel comes off in the conventional art, help the maintenance of electrolytic solution purity and stablizing of amount of electrolyte, the part that the conductive copper core contacts with public busbar is that the pollution on plane and little its surface of area is eliminated easily, the conductivity of cathode for electrolytic manganese and the stability of conduction have been improved, cathode resistor does not increase with the increase of its duration of service, it is constant to be maintained the 90 micro-ohm left and right sides, does not need to carry out irregularly artificial rust cleaning and re-assemblies negative electrode; Current conducting rod is a stainless material because of its skin, and the physical strength height is not yielding, and has saved the copper material consumption, reduced cost, the routine maintenance of negative electrode is simple and easy, and labor strength greatly reduces, the serviceability rate height of negative electrode, long service life helps enhancing productivity.By use test, the purity of electrolytic manganese improves about 0.003-0.006%, each production cycle of monolithic negative plate (24 hours) electrolytic manganese output is brought up to the 3.5-3.8 kilogram by the 3.3-3.5 kilogram, the power consumption of electrolytic manganese per ton has reduced 3-5%, monolithic negative electrode copper consumption reduces makes an appointment with half, reduced production cost, the width that the conductive copper core contacts with public busbar is increased to more than the 11mm, contact area increases, conductive copper core and public busbar contact position applying degree are good, reduced contact resistance, use handle to be convenient to check the electrodeposition quality of negative plate in the electrolytic deposition process, in follow-up production process, use handle can realize mechanize production, alleviate working strength of workers, improved production efficiency.

It needs to be noted: copper is national grand strategy goods and materials, also is international rare noble metal resource, and conventional art fine copper current conducting rod consumption copper is many, exceeds the conduction demand, has greatly wasted the copper resource, needs to consume a large amount of foreign exchanges and carries out import.The utility model adopts structure design cleverly; greatly reduce the copper material consumption; saved the copper resource effectively; this is very great for the scarce resource of preserving our planet, energy-saving and cost-reducing, environmental protection, saving foreign exchange meaning; also be the current global low-carbon economy of carrying out, a new measure of transforming mode of economic growth.
