Description
Technical field
The invention belongs to Copper making equipment technology field, mainly a kind of cupric electrolysis cathode collector bar.
Background technique
Currently, using big pole plate stainless steel cathode in cupric electrolysis technique is state-of-the-art technology.The group of stainless steel cathode
It is formed at by conductive rod and stainless steel plate, in the identical situation of the material trademark of stainless steel plate, the structure of conductive rod is directly affected
To the electric conductivity of cathode plate.
Existing conductive rod structure uses arc surface form when contact position designs, and is in point when conductive rod is connect with bus bar
Contact, on the one hand causes contact resistance higher since contact area is small, secondly work of the cathode plate of point contact in electrolysis cycle liquid
It is easy to produce shaking under or verts, cathode plate current density is caused to be unevenly distributed；Secondly existing conductive rod structure size without
Method meets high current production requirement, therefore after researching and developing a kind of big contact resistance bottom of current-carrying capacity and preferably capable of keeping cathode hangs
The cathode plate of plumbness is very necessary.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and a kind of cupric electrolysis cathode collector bar is provided, made
The service performance of cathode plate improves.
The object of the present invention is achieved by the following technical solutions.This cupric electrolysis cathode collector bar mainly includes
Stainless steel sleeve, solid copper bar, one layer of stainless steel sleeve of solid copper bar outsourcing are interference fitted close between stainless steel sleeve and solid copper bar
In conjunction with seamless；The solid copper bar of package is exposed a distance formation by Milling Process stainless steel sleeve to be used for and conductive bus bar
The contact of connection.
The solid copper bar rectangular cross-section structure.
The copper content of the solid copper bar must reach T2 requirement, the arc chord angle half at four angles in solid copper bar section
Diameter should be less than 0.5mm.
The cross-sectional width of the solid copper bar must between 24mm-30mm, depth of section must 34mm-44mm it
Between.
The wall thickness of the stainless steel sleeve must be between 3mm-4mm.
The same side positioned at solid copper bar both ends width direction of the contact.
The invention has the benefit that solid copper bar section is rectangle, base contact surface is big, is a reduction contact electricity
Resistance, improves the conductive rod of current efficiency, greatly improves the service performance of cathode plate.
Detailed description of the invention
Fig. 1 is stereoscopic schematic diagram of the invention.
Fig. 2 is side structure schematic view of the invention.
Fig. 3 is schematic view of the front view of the invention.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
As shown in Figure 1-3, this cupric electrolysis cathode collector bar, mainly includes stainless steel sleeve 1, solid copper bar 2, solid copper bar
2 one layer of outsourcing stainless steel sleeve 1 are interference fitted close connection between stainless steel sleeve 1 and solid copper bar 2；It is stainless by Milling Process
The solid copper bar 2 of package is exposed a distance and forms the contact 6 for being used to connect with conductive bus bar by steel bushing 1.
The stainless steel sleeve 1 is made of the good stainless steel material of corrosion resistance；Solid copper bar 2 constitutes conductive layer, real
2 rectangular cross-section structure of heart copper rod, base contact surface is big, reduces contact resistance, improves current efficiency.
5 radius of arc chord angle at 2 four angles in section of solid copper bar should be less than 0.5mm, to guarantee that conductive rod and conduction are female
The face of row's contact maximizes, to reduce contact resistance；Simultaneously using energy when can be cathode hangs after face contact in electrolytic cell
It enough is remain stationary cathode plate, improves the Vertical performance of cathode plate, keeps current distribution more uniform.
The cathode plate of existing copper electrolysis process and the center spacing of anode plate are 50mm, and current density is about 350A/m2, this
Scheme is to have evaded conductive rod size super large to lead to the risk of short circuit, while also making the current-carrying capacity of conductive rod in the base of traditional structure
It is substantially improved on plinth, implementation are as follows: the copper content of the solid copper bar of conductive rod must reach T2 requirement, and cross-sectional width 3
Must be between 24mm-30mm, depth of section 4 must be between 34mm-44mm.This programme maximum can bear the electric current of 1500A,
Even if there is conductive non-uniform situation, occur can be used normally when electric current is substantially increased.
According to previously described cupric electrolysis cathode collector bar, stainless steel sleeve had both played the role of corrosion resistant, also functioned to simultaneously
Enhance the effect of conductive rod rigidity, this programme must guarantee the same of rigidity between 3mm-4mm using the wall thickness of stainless steel sleeve
When do not make conductive rod width it is excessive lead to anode and cathode short circuit phenomenon generate.
Solid copper bar part is exposed in the same side positioned at 2 both ends width direction of solid copper bar of the contact 6, i.e. two sides
Contact 6 is located at the same side of conductive rod both ends width direction.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
