Description
Technical field
The present invention relates to electrode for electrolysis, more specifically, relate to the electrode for electrolysis that in make the tinsel of electrolytic copper foil etc. by electrochemical plating, uses.
Background technology
By electroplate making in the tinsel, in recent years, electrolyzer tends to big electric currentization and maximization, as the electrode for electrolysis of insoluble anode, and at present known curved surface shape electrode that can save spaceization.For example, in patent documentation 1, disclose and positive plate has been installed also crooked on housing by bolt, thereby form circular-arc structure, devices spaced apart is provided with this circular-arc positive plate around the round tube type negative electrode that rotates freely, by there being electrolytic solution therebetween, can be at cathode surface precipitating metal paper tinsel.In addition, by between positive plate and housing, inserting and putting contactless ring, and change the thickness of this contactless ring, can adjust the interval of positive plate and negative electrode.Thus, the interval of positive plate and negative electrode is kept necessarily on the whole, and make current density even, just can realize the thickness homogenizing of the metallic film of separating out.
Yet, in the structure of patent documentation 1, positive plate is installed on housing to carry out from the opposition side inserting bolt with respect to housing and positive plate, therefore in order to change the thickness of contactless ring, just need carry out the installing/dismounting operation of bolt in the outside of housing, and need carry out the installing/dismounting operation of positive plate in the inboard of housing, so there is the such problem of complicated operation.
Therefore, in patent documentation 2, as shown in Figure 4, disclose in the inner face side (side relative) that forms the 1st circular-arc electrode matrix 51 with not shown negative electrode, through intermediate materials 52,53 the 2nd circular-arc electrode matrix 54, the structure of fixing the 2nd electrode matrix 54 from the inner face side of the 1st electrode matrix 51 by bolt 55 are set.As shown in Figure 5, a plurality of the 2nd electrode matrixs 54 are arranged on the inner peripheral surface of the 1st electrode matrix 51, can switch on to whole the 2nd electrode matrix 54 integral body through the 1st electrode matrix 51 from bus 56.According to the structure of patent documentation 2, under the situation of underway material 52,53 thickness adjustment, can carry out only the operation of replacing intermediate materials 52,53 being installed, in the hope of realizing the raising of operability in the inner face side of the 1st electrode matrix 51.
Yet, carry out interval adjustment with negative electrode respectively for each the 1st electrode matrix 51, still have problems in operating aspect, also existing room for improvement aspect this.

Embodiment
Below, with reference to accompanying drawing embodiments of the present invention are described.Fig. 1 is the sectional view of the electrode for electrolysis of an embodiment of the invention, and expression is used for the anodic situation of electrolyzer.
As shown in Figure 1, it is circular-arc that electrode for electrolysis 1 forms the cross section, and in the present embodiment, 2 electrode for electrolysis 1,1 are arranged to semicircle shape, and double as is the cell wall of electrolyzer 2.On the inner face side of electrode for electrolysis 1,1, the drum type negative electrode 4 that the devices spaced apart setting can be rotated makes along the circumferential direction basicly stable between the space.In electrolyzer 2, can be by the 2a of feeding portion that between adjacent 2 electrode for electrolysis 1,1, is provided with, supply electrolytic solution L, the electrolytic solution L of supply as shown by arrows, pass through between electrode for electrolysis 1,1 and negative electrode 4, the discharge gutter 2b, the 2b that are provided with from the left and right sides at electrolyzer 2 discharge to the outside.
Fig. 2 is the sectional view of wanting portion that amplifies expression electrode for electrolysis shown in Figure 1.Fig. 3 is the sectional view that it is further amplified expression.As shown in Figures 2 and 3, the inner face side of the base material 10 that electrode for electrolysis 1 is circular-arc in the cross section (towards a side of the negative electrode 4 of Fig. 1) is provided with a plurality of same circular-arc battery lead plates 12 in cross section and constitutes.At battery lead plate 12 is by inserting the communicating pores 10a of matrix 10 to the outstanding protruding 12a of foreign side, clamping matrix 10 between power supply board 12 and power supply board 16, from the exterior side of power supply board 16 (side opposite) bolt 18 is twisted at the head of above-mentioned protruding 12a and to close, thereby battery lead plate 12 is fixed on the matrix 10 with the negative electrode 4 of Fig. 1.Matrix 10 for example can be made of the titanium plate, and battery lead plate 12 for example can be made as the insoluble electrode with the inner face side of coating titanium plates such as Indium sesquioxide.
Form the elastomerics 20,22 that cyclic elastomeric material etc. has insulativity existing between battery lead plate 12 and the matrix 10 and between matrix 10 and power supply board 16.
Permutation disposes each battery lead plate 12, and whole inner face side of matrix 10 all are capped, and guarantees to have the space S of insulation usefulness respectively between it.The distribution 16a that is made of single core cable by linking to each other with power supply board 16 in each battery lead plate 12 is along direction of arrow supply electric current, the structure that formation can be powered respectively.
According to electrode for electrolysis 1 with said structure, inconsistent at each battery lead plate 12 with the interelectrode distance generation of negative electrode 4, current density may become under the uneven situation, need not to adjust as at present interelectrode distance, can adjust the current value to 12 power supplies of each battery lead plate respectively.Particularly, at the interelectrode distance of measuring hour, can improve power supply current value, on the other hand, when interelectrode distance is big, can reduces power supply current value, thereby can make the electric current distribution homogenizing of negative electrode, only pass through to adjust power supply current value, thereby can easily make the thickness homogenizing of precipitating metal.Therefore as mentioned above, the relation that interelectrode distance and power supply current value are inversely proportional by making power supply current value pictorialization or the formulism corresponding with interelectrode distance in advance, thereby can more easily determine the power supply current value of every electrode plate 12.
In addition; between matrix 10 and battery lead plate 12, be gripped with under the state of insulativity elastomerics 20; battery lead plate 12 is fixed on the matrix 10, therefore can reliably prevent the leakage of the electrolytic solution L of storage in electrolyzer 2, can guarantee the electrical isolation between matrix 10 and the battery lead plate 12 simultaneously.
In addition, owing between matrix 10 and power supply board 16, also be gripped with elastomerics 22, thereby can stably power to battery lead plate 12 by power supply board 16, by the adjustment power supply current value, control current density exactly just.
