Abstract

The invention belongs to the metallurgical field, and more specifically relates to a novel electricity-saving anode plate. According to the novel electricity-saving anode plate, a plate body is a single-layer plate or a three-layer plate; the single-layer plate is a tin bronze anode plate or an aluminium bronze anode plate; and the middle layer of the three-layer anode plate is a copper sheet, and the outer layer of the three-layer anode plate is a lead plate. Red copper is taken as a basic conductive material due to the high electrical conductivity, and then modified to bronze through addition of tin and aluminium; tin bronze and aluminium bronze are durable, high in hardness and high in corrosion resistance; and the electrolytes of a main material pure copper, and electro-deposited copper have the same property, and an electro-deposited solution cannot be polluted when production losses are generated by the pure copper. The three-layer composite anode plate taking the red copper plate as a conductive interlayer and combining the red copper plate with the lead material greatly provides the excellent electrical conductivity of an anode. The novel anode plate structure capable of saving production materials while keeping the conductive performance invariable provides a space for reduction of the production cost of the anode plate.

Description

A kind of novel power saving positive plate

Technical field

The invention belongs to field of metallurgy, more specifically, relate to a kind of novel power saving positive plate.

Background technology

It is known that, metal produces underlying metal raw produce by smelting, there are pyrometallurgy and the two kinds important technology mode of hydrometallurgy at present, ordinary circumstance, hydrometallurgy is by cupric, the raw material of the mineral such as zinc, with acid or alkaline solution, employing Leaching way leaches, then through extracting and enriching, the process that electrodeposition produces, and electrolytic deposition process is by a cell, it is provided with insoluble conductive anode and starting sheet (minus plate) negative pole, under unidirectional current effect, pump people's electrolysis bath after enrichment being called, the metal cation of electricity rich solution precipitate on starting sheet (minus plate) negative pole, produce the products such as required electro deposited copper and electro deposited zinc, and insoluble anode plate is as durable conductive electrode, fixing also life-time service in a cell.During this, minus plate is precipitated out the yield of product by the electric conductivity of positive plate, often precipitates out the power consumption of ton product, plays vital effect.The kind of current positive plate needs according to the character of different precipitating metal products, of a great variety, has lead base binary, polynary positive plate, and titanium is according to alloy anode plate, copper. aluminium anodes plate, stainless steel anode plate etc..Carry the effect of electrodeposition, electrolytic deposition, plating.In current hydrometallurgical technology most widely used general, the wet method electro deposited copper of product scale super large and wet method electrolysis deposition zinc, the two metal species, wet method electro deposited copper annual production Chilean, the U.S. just crosses 2,000,000 tons in 1989, about 60,000 tons at present of China, nearly ten million ton of the wet electrolytic zinc annual production whole world, China has reached more than 4,000,000 tons, and wherein only Yunnan one province produces nearly 1,000,000 tons per year.In the two metal species, the positive plate of electrolysis electrodeposition production and application, essentially lead-based anode plate, and the effort that current each electrode science-and-technology enterprise does for positive plate economize on electricity, all concentrate on the element such as silver, calcium, strontium and rare earth to add, and plate shape and plate shape rolling technique aspect.Increasing its metal hardness, compact crystallization, though there being power savings, but fundamentally not solving economize on electricity problem.

Summary of the invention

The present invention is just for the problems referred to above, it is provided that a kind of novel power saving positive plate.To achieve these goals, the present invention adopts the following technical scheme that, plate body is lamina or three ply board, single layer anode plate is tin bronze positive plate or aluminium bronze positive plate, the intermediate layer of three layers positive plate is copper sheet, and outer layer is two-sided for stereotype, is pressed into composite board through embedded.In tin bronze positive plate, the content of stannum is 3～14%, and other is the pure red copper of more than No. 1, and the thickness of plate is 0.5～5mm.In aluminium bronze positive plate, the content of aluminum is 4～10%, and other is the pure red copper of more than No. 1, and the thickness of plate is 0.5～5mm.In three layers positive plate, the thickness of copper sheet is 0.5～3mm, and the thickness of stereotype is 1～3mm.Three blocks of plates of three layers positive plate are embedded rolling of pressurizeing.Plate body is also provided with crossbeam and hanger.On nodal wood type plate body, be also provided with protection section with liquid level intersection, the integral thickness of protection section than plate body thick one times at most times.The plate body above protection section on nodal wood type three layers positive plate plate body is monolayer copper sheet。

Beneficial effects of the present invention:

Tin bronze and aluminium bronze have durable, hardness is big, anticorrosive property good, and main material fine copper is the same with the electrolyte properties of electro deposited copper, and it will not pollute electric effusion when producing to produce loss.Due to the electric conductivity that red copper is good, conductive material based on red copper, it is modified as bronze at addition stannum and aluminum, and red copper is as the compound of conducting interlayer with plumbous material, provides the good electric conductivity of anode all greatly.Tank voltage drops to 0.8v 1.2v when copper electrodeposition from 1.8v 2.2v, drops to 2.0v 2.2v from 3.0v 3.2v during zinc electrolysis, thus when electric current density is consistent with lead anode, respectively reaches the effect of consumption reduction economize on electricity 55% and 30%.Inner clip fine copper has good electric conductivity, and outer lead-sheathing is durable, anticorrosive, is suitable for heavy current density production, and the lead loss produced in production process will not pollute zinc electrolyte, does not cause and is worth higher copper loss mistake.
