Description
Technical field
The present invention relates to a kind of negative plate, be meant a kind of stainless steel cathode plate that is used for the electrolysis industry especially.
Background technology
Along with technical progress, stainless steel cathode plate in the application of copper refining enterprise more and more widely, its developing state will progressively substitute traditional copper starting sheet.The stainless steel cathode electrolysis tech is world's modern technique, is representing the top level of copper refining.Use stainless steel cathode plate at the copper refining business enterprise expand and have vast potential for future development.Right present negative plate structure generally comprises current conducting rod, negative plate plate body, connects sheath, insulating clamp edge strip; Current conducting rod is the quadrate current conducting rod; The end face of negative plate plate body and current conducting rod one plane contact; Weld with being connected sheath then, the insulating clamp edge strip then is installed on the dual-side of negative plate plate body, and the negative plate plate body is provided with the quadrate erection opening.There is following problem in said structure: 1. current conducting rod and negative plate plate body, and the negative plate plate body is firm inadequately with being connected of sleeved; 2. current conducting rod is square, and distribution of current is uneven between the guide of electrolyzer, and current conducting rod is prone to be heated high temperature, causes resistance to raise, and the efficient of electric current is lower; 3. current conducting rod is that contacting between square and the guide is the contact of face face, in case it is out-of-level contact surface to occur, negative plate so very likely occurs and is not in vertical state, thereby cause the electrolytic copper that adsorbs on the negative plate inhomogeneous; 4. quadrate erection opening, negative plate is prone to shake during lifting, causes the negative plate plate body not vertical, and it is inconvenient to place negative plate.
Summary of the invention
Technical problem to be solved by this invention is: a kind of stainless steel cathode plate is provided, and this stainless steel cathode plate is firm, and the utilising efficiency of electric current is high, the contact surface of the guide of electrolyzer and current conducting rod level whether no matter, and the negative plate plate body is in vertical state all the time.
For solving the problems of the technologies described above; Technical scheme of the present invention is: stainless steel cathode plate; Comprise the negative plate plate body of copper current conducting rod, stainless steel, the sleeved of stainless steel; And the insulating clamp edge strip, the periphery of said current conducting rod comprises three square and an arc surface, offers axial draw-in groove at the bottom of the arc of the arc surface of said current conducting rod; The periphery that said sleeved is sleeved on current conducting rod closely contacts with current conducting rod; This sleeved comprises three smooth plates that cooperate with three square of current conducting rod; And two skewbacks corresponding with arc surface, constituting and the adaptive opening of negative plate plate body thickness between the said skewback, the length of said current conducting rod is greater than sleeved length; Sleeved length is greater than the width of negative plate plate body, and expose at the relative sleeved two ends of said current conducting rod; One end of said negative plate plate body and draw-in groove shrink-fit; The other end end of said negative plate plate body is along being provided with V-shaped groove; Said negative plate plate body and two skewback welding, said negative plate plate body is provided with erection opening, and the dual-side of said negative plate plate body clamps the insulating clamp edge strip.
As a kind of preferred scheme, the length of said V-shaped groove is less than the width of negative plate plate body, the end of said V-shaped groove and negative plate plate body side between spacing be fit to the installation of insulating clamp edge strip.
As a kind of preferred scheme, said V-shaped groove is 90 ° a V-shaped groove.
As a kind of preferred scheme, the both ends open mouth that said sleeved exceeds negative plate plate body width fits tightly and welds fixing along guide torch arc surface.
As a kind of preferred scheme, said sleeved exceeds between the arc surface of openings at two ends mouth edge and current conducting rod of negative plate plate body width and is perfused with the sealing conductive resin.
As a kind of preferred scheme, said copper current conducting rod is a purity greater than 99% electrolysis copper rod.
As a kind of preferred scheme, the negative plate plate body that the negative plate plate body of said stainless steel is processed for the 316L stainless-steel sheet.
As a kind of preferred scheme, said two skewbacks respectively with the smooth plate of the corresponding connection of sleeved between angle be 110 °.
As a kind of preferred scheme, said erection opening be shaped as ellipse, the axis normal of this oval-shaped major axis and current conducting rod.
After having adopted technique scheme, effect of the present invention is: because the periphery of current conducting rod comprises three square and an arc surface, offer axial draw-in groove at the bottom of the arc of arc surface; Therefore; The draw-in groove shrink-fit of negative plate plate body and current conducting rod, and the skewback of sleeved and the welding of negative plate plate body, the contact surface of skewback and negative plate plate body is big; Weld more firm; And two holding forces that the common anticathode plate of skewback plate body one makes progress, like this, being connected between negative plate plate body and the current conducting rod, between negative plate plate body and the sleeved is all very firm.Simultaneously, contact with the guide of electrolyzer at the bottom of the arc of the arc surface of current conducting rod, contact is the line contact so; Avoid it to contact inequality between the two and caused the uneven problem of distribution of current; Also avoided causing the current conducting rod heating, avoided electrical loss like this, improved electrical efficiency because of distribution of current is uneven; Under the action of gravity of negative plate plate body, the negative plate plate body is in vertical state all the time simultaneously, avoids the negative plate plate body to tilt like this, and it is uneven to cause electrolytic copper absorption, also avoids contacting between the negative plate plate body.In addition; Because the existence of two skewbacks; Therefore there is cavity between skewback and the current conducting rod cambered surface, when peeling off electrolytic copper, possibly needs hammering negative plate plate body, therefore; Cavity can play shock absorption, thereby avoids the weld seam of negative plate plate body and sleeved directly stressed excessive and crackle occurs.
Again because the both ends open mouth that said sleeved exceeds negative plate plate body width fits tightly and welds fixing along guide torch arc surface.Therefore, the sleeved two ends then closely contact with current conducting rod, avoid acid solution or other impurity to enter into the cavity between skewback and the current conducting rod cambered surface and cause corrosion.
Again since erection opening be shaped as ellipse, the axis normal of this oval-shaped major axis and current conducting rod, so suspension hook colluding the major axis end of erection opening, negative plate is very reliable, the negative plate plate body is in vertical state all the time, is difficult for rocking.
