Background technology
Electrolysis is the abbreviation that electricity decomposes, make anode and negative electrode in pairs and under the state that impregnated in electrolytic solution or melt salt to both in pass into galvanic current, at electrode surface generation chemical transformation, decomposition is carried out to material refining.
Such as, the wet type refining of metal, metal plating are by metal is applied voltage as anode, thus make to punish at anode the metal separated and separate out in cathode surface or the example of electrolysis process forming overlay film with the state that purity is higher.
On the other hand, by electrolytic solution being adjusted to suitable pH condition, also can the dissolving metal making to have decomposed in the anode in electrolytic solution and to movable cathode time, by carrying out precipitating as oxyhydroxide before negative electrode place and carry out being separated (for example, referring to patent documentation 1) separating out.
As shown in patent documentation 2, the anode most cases used in electrolysis is anode 100 as shown in Figure 10.Anode 100 is configured as one piece has projection 101 tabular component on top, by by this projection 101 hooking or hang on power supply 102 etc. and be electrically connected with power supply 102.
In the electrolysis employing this anode 100, between the projection 101 and power supply 102 of anode 100, produce the fever phenomenon caused by resistance.In anode 100, because this heating is related to power loss, therefore done one's utmost to suppress.But, it cannot be made not generate heat completely.
In addition, this fever phenomenon is not rise to make that the anode formed by common metal such as copper softens, the temperature of the degree of melting.But, when using metal or alloy lower for fusing point as tin or indium etc. as anode 100, if pass into larger voltage, electric current, then can produce the softening transform or anode 100 self cannot be supported and the problem be shed in electrolyzer reaching the contact place between the projection 101 of the highest temperature and power supply 102 and making projection 101 melting because its heating.
For this problem, when anode 100 of common one-piece type shape as shown in Figure 10, because the contact area between projection 101 and power supply 102 is very little, therefore cannot heating when passing into larger voltage, electric current be suppressed lower.Therefore, be difficult to prevent coming off of anode 100.Thus, when anode 100, must terminate electrolysis treatment within the short period of time to coming off, operability is deteriorated, or also voltage, electric current have to be suppressed to obtain lower method of carrying out electrolysis by existence, and the precipitation efficiency of metal is deteriorated.
In addition, Patent Document 3 discloses a kind of method, in the method, as shown in figure 11 in the formation hole, Liang Ge position, top 104 of the battery lead plate 103 of anode, utilize conduction fastening means 105 to hang on the metal bar 106 of power supply, metal bar 106 is electrically connected with power supply 107.In addition, Patent Document 4 discloses a kind of method, in the method, on battery lead plate 108, the metal hangers 109 of band shape be arranged on two positions as shown in figure 12 and hang on the metal bar 110 of powering, metal bar 110 is electrically connected with power supply 111.
But, in the method described in patent documentation 3, conduction fastening means 105 only carries out point cantact in each hole with battery lead plate 103, therefore the temperature of contact part cannot be suppressed to rise when passing into larger voltage, electric current, when the low melting point metal such as tin, indium being used for battery lead plate 103 of anode, to soften, melting coming off.
In addition, the method described in patent documentation 4 is the method for the more use of electrode as cathode side, but this structure is also used in the anode.In the method described in patent documentation 4, rivet is utilized to be engaged with battery lead plate 108 by metal hangers 109 at two positions as shown in figure 12.Because this metal hangers 109 reliably contacts with metal bar 110, because being employed herein the good thinner metal of processibility, being easy to easily be out of shape, therefore in the engaging process of rivet, also creating distortion, be difficult to have carried out sufficient face and engage.In addition, according to the application target of suspension bracket 109, as long as commonly can holding electrode plate 108 fully, just do not use the wider metal of required above width.In the method described in this patent documentation 4, although compared with the point cantact that the method described in patent documentation 3 is such, temperature rises and relaxes a little to some extent, but for the battery lead plate of the low melting point metal such as tin, indium or low melting point alloy, effect is also insufficient, producing when passing into larger voltage, electric current softening, near the junction surface between metal hangers 109 and battery lead plate 108, being applied with the deadweight that top does not have the place of maintaining part etc., start to produce the distortion that causes by conducting oneself with dignity and come off.

Conductive connecting component 6 is with at least and the tabular of the mode of the whole surface contact of retaining member mounting face 2a of battery lead plate 2 the being formed as tabular length that is formed as having more than the length of the retaining member mounting face 2a of battery lead plate 2 and the sufficient width that bolt 5 can be utilized to be connected as one the connection portion between battery lead plate 2 and battery lead plate retaining member 4.Preferably, conductive connecting component 6 uses the good metal of electroconductibility.The mode that this conductive connecting component 6 contacts with face is connected to battery lead plate 2, thus the connection portion between battery lead plate 2 and conductive connecting component 6, even if temperature rises because of resistance, also can make heat diffusion and prevent the melting of battery lead plate 2, even if when having passed into larger voltage, electric current, the melting of battery lead plate 2 also can have been prevented.In addition, even if temperature rises because of resistance and how much creates softening, because the retaining member mounting face 2a entirety of battery lead plate 2 is connected with conductive connecting component 6, therefore also coming off of battery lead plate 2 can be prevented.
Method of attachment between battery lead plate 2 and retaining member 3 as depicted in figs. 1 and 2, under the state making battery lead plate retaining member 4 butt up against battery lead plate 2, utilize two pieces of conductive connecting components 6 from the side, namely two interarea sides of battery lead plate 2 clamp the connection portion between battery lead plate 2 and battery lead plate retaining member 4, make bolt 5 respectively through battery lead plate 2 and two pieces of conductive connecting components 6 and battery lead plate retaining member 4 and two pieces of conductive connecting components 6, and holding bolt 5 and not shown nut.Now, also the communicating pores 9 of a piece in two pieces of conductive connecting components 6 can be set to the threaded hole corresponding with bolt 5, not use nut but use conductive connecting component 6 and bolt 5 to come fastening electrode plate 2 and battery lead plate retaining member 4.Thus, battery lead plate 2 with there is the retaining member 3 one-tenth of battery lead plate retaining member 4 with two pieces of conductive connecting components 6 be integrated, utilize bolt 5 and conductive connecting component 6 electrode electrically connected plate 2 and battery lead plate retaining member 4.As shown in Figure 2, battery lead plate 2, battery lead plate retaining member 4 and conductive connecting component 6 are pre-formed the communicating pores 7,8,9 run through for bolt 5.When utilizing this method of attachment to connect, as shown in Figure 1, show the example respectively having installed 4 bolts 5 respectively on battery lead plate 2 and battery lead plate retaining member 4, but be not limited thereto, preferably utilize multiple bolt 5, preferably utilize the bolt 5 of more than 3 to connect, particularly preferably be, in order to battery lead plate 2 being firmly fixed at retaining member 3 and avoiding the complicacy of operation and be set to 3 or 4.As long as the interval of bolt 5 symmetrically fully expansion at equal intervals.
In addition, as shown in Figure 3, battery lead plate 2 also can be the battery lead plate communicating pores 7 run through for bolt 5 being set to groove portion 7a.Groove portion 7a is located at the peripheral part relative with battery lead plate retaining member 4 of battery lead plate 2, and the upper end side opening relative with battery lead plate retaining member 4 carries out cutting and being formed as channel-shaped with the width more than diameter of bolt 5.The shape of groove portion 7a is not limited to the groove portion of the U-shaped shown in Fig. 3, such as also can be set to the groove of triangular shape, quadrilateral shape, as long as the groove portion 7a of bolt 5 penetrating electrode plate 2 can be made and battery lead plate 2 is installed on battery lead plate retaining member 4, it can be just arbitrary shape.
Even if when employ shown in Fig. 3 battery lead plate 2, also can ground identical with the situation shown in Fig. 1 connection electrode plate 2 and transom 3.Two interareas of the battery lead plate 2 utilizing two pieces of conductive connecting components 6 to clamp to have docked and battery lead plate retaining member 4, make bolt 5 respectively groove portion 7a and the two piece conductive connecting component 6 of penetrating electrode plate 2 and battery lead plate retaining member 4 and two pieces of conductive connecting components 6, holding bolt 5 and not shown nut.By utilizing two pieces of conductive connecting components 6 to clamp battery lead plate 2, even thus be formed as the groove portion 7a of channel-shaped, also can not the mode that falls of self-electrode plate retaining member 4 can install with battery lead plate 2.
When shown in Fig. 3 battery lead plate 2, be not be set to communicating pores by the part that will run through for bolt 5, but be set to the groove portion 7a of channel-shaped, thus easily can install relative to battery lead plate retaining member 4, dismantle battery lead plate 2.Such as, when changing battery lead plate 2 when operate continuously, bolt 5 need not be unloaded and two blocks of conductive connecting component 6 self-electrode plates 2 are separated completely with battery lead plate retaining member 4, just can easily unload the battery lead plate 2 of finishing using from retaining member 3 by means of only lax bolt 5.And, under the state of retaining member 3 having dismantled battery lead plate 2, by new battery lead plate 2 is inserted between conductive connecting component 6 in the mode of bolt 5 embedded groove portion 7a, and holding bolt 5, thus can easily fixed plate electrode 2.Like this, be formed with the installation of the battery lead plate 2 of groove portion 7a, dismounting is easier to, therefore, it is possible to improve operation efficiency.
When shown in Fig. 1 retaining member 3, by utilizing two pieces of conductive connecting components 6 to clamp battery lead plate 2 and battery lead plate retaining member 4, and utilize bolt 5 and conductive connecting component 6 to maintain connection state, thus battery lead plate 2 kept in the electrolytic solution.In addition, retaining member 3 is by conductive connecting component 6 electrode electrically connected plate 2 and battery lead plate retaining member 4, and electrode electrically connected plate 2 and the power supply for electrical connection section 4a hooking.
As retaining member 3, be not limited to the retaining member shown in Fig. 1, as simpler method, such as, also can adopt with the following method: the holding force that utilization uses spring and obtains carries out dismounting with single job.But, in this case, need as when clamping battery lead plate 2 at the retaining member 3 utilized shown in Fig. 1 can with battery lead plate 2 firmly earth surface design on make an effort, movable part becomes many, therefore avoids the countermeasure of electrolytic corrosion to become more important and maintenance etc. complicate.Therefore, when long-time use, preferred structure is simpler, the retaining member 3 employing bolt 5 shown in Fig. 1.In addition, as retaining member 3, as long as can holding electrode plate 2, battery lead plate 2 can be made to be electrically connected with power supply, just also only can be installed on the retaining member mounting face 2a of an interarea of battery lead plate 2.
For the anode 1 by Structure composing such above, even if battery lead plate 2 is formed by low melting point metal or low melting point alloy, battery lead plate 2 also contacts in face with the conductive connecting component 6 in retaining member 3, such as Fig. 1, therefore, even if create resistive heating in connection portion, heat also can spread and suppresses temperature to rise and can prevent the melting of battery lead plate 2, even if how much create softening in addition because of resistive heating, by utilizing the retaining member mounting face 2a of retaining member 3 holding electrode plate 2 entirety also can prevent coming off of battery lead plate 2, long electrolysis can be carried out.In anode 1, because battery lead plate 2 and retaining member 3 contact, even if therefore when having passed into larger voltage, electric current to battery lead plate 2, battery lead plate 2 also can not come off, and can carry out long electrolysis.In addition, even if anode 1 has thickened the thickness of battery lead plate 2, even the thickness of such as more than 8mm, also remain and can not fall by self-sustaining component 3, therefore, it is possible to carry out long electrolysis.
The manufacture method > of < 2. anode
About the manufacture method of anode 1, first the manufacture method of battery lead plate 2 is described.Battery lead plate 2 uses the mold corresponding to the shape of battery lead plate 2 by casting to manufacture.
Specifically, the battery lead plate 2 used in the anode 1 shown in Fig. 1 and Fig. 2 use as shown in Figure 4 and Figure 5, such as formed on the plate of the graphite carbon of adequate thickness and the sizable recess 10a of battery lead plate 2 and the mold 10 that obtains and formed.By using the mold 10 of graphite carbon, thus when heating, heat is easy to the metal transmission to putting into recess 10a, is therefore easy to make melting of metal, and is easy to the metal taking out solidification from mold 10 after the cooling period.
Mold 10, except graphite carbon, is considered based on thermotolerance aspect, also can be used the mold of tetrafluoroethylene, refractory metal.But, when using tetrafluoroethylene, because thermal conductivity is poor, therefore spended time till making metal melting, not preferably.When using refractory metal, because the wettability between the low melting point metal after melting or low melting point alloy raises, be difficult to when taking out at cooling curing peel off from mould, thus not preferred.Thus, as thermal conductivity better and the less and good material of separability of the distortion caused by thermal expansion, preferred graphite carbon.The size of mold 10 is determined according to the thickness of battery lead plate 2, the size of width.In the recess 10a of mold 10, in order to more easily take out the battery lead plate after cooling curing 2, the mode also can expanded towards opening from bottom surface with inwall arranges angle.
