Accompanying drawing explanation
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates the front view of the galvanic deposit anode of the utility model one embodiment.
Fig. 2 illustrates the front view of the galvanic deposit anode of another embodiment of the utility model.
Embodiment
Embodiment of the present utility model changes the conventional way that layer of precious metal covers at substrate surface 100%, and the reasonable working range of the current density of take is foundation, redefines layer of precious metal in the area coverage of substrate surface, thereby saves the materials of precious metal.
Be appreciated that insoluble anode can normally be used under certain anodic current density.For example, titanium is coated with iridium anode, and the anode of Ji Yitaiwei basic unit and covering precious metal iridium layer can be no more than 2A/dm in current density
2condition under use more than 3 years.
The quality that guarantees higher current efficiency and reclaim metal when electro-deposition techniques is applied to metal concentration lower than the waste water of 10g/L or waste liquid, is subject to the restriction of concentration polarization factor, in order to be worked under a limit current density.It is lower that general GOLD FROM PLATING SOLUTION belongs to ionic concn, and limit current density is less.With acid copper-containing solution galvanic deposit, be recovered as example, in the situation that copper ion concentration is 5g/L, can keep 80% above current efficiency, can obtain again the working current of fine texture metallic copper at 0.5A/dm
2left and right.
The shape of cathode and anode determines by the shape of electric deposition device, and the galvanic deposit chamber that is generally used for the electric deposition device that waste water or waste liquid reclaim is square carriage body structure, and cathode and anode is tabular, and yin, yang is alternate, and to be installed on galvanic deposit indoor.In order to obtain the metal of even thickness at negative plate, area and the shape of general anode and negative electrode are basic identical, and yin, yang pole plate is opposed.In the certain situation of cathode current density, negative plate area can reclaim more metals more greatly, certainly also needs more positive plate corresponding with it.
Yet, when application electrodip process reclaims in waste water or waste liquid metal, between the reasonable working current density of negative electrode and positive electrode, there are differences.Cathode current density mainly belongs to Determination of ionic concentration according to GOLD FROM PLATING SOLUTION, and under this current density, anodic current density is in very low level.With acid copper-containing solution galvanic deposit, be recovered as example, when copper ion concentration is 5g/L, more suitable current density is 0.5A/dm
2, because annode area is suitable with negative electrode, anodic current density is also 0.5A/dm
2.By contrast, aforesaid titanium be coated with iridium anode can be up to 2A/dm
2current density under normally work, the high-performance of insoluble anode that this has just meaned routine techniques " waste ".
The utility model, by all subtracting the precious metal area coverage of insoluble anode, reaches and saves tectum cost, guarantees all objects of even recovery metal quality of distribution of current simultaneously.
According to embodiment of the present utility model, a kind of galvanic deposit anode is proposed, be characterized in, only at galvanic deposit anode part surface coverage layer of precious metal.Layer of precious metal in the area coverage of galvanic deposit anode surface so that galvanic deposit anode meets the maximum current density of license is as the criterion.
Fig. 1 illustrates the front view of the galvanic deposit anode of the utility model one embodiment.Shown in Fig. 1, galvanic deposit anode 10 comprises single base material 11 and layer of precious metal 12.Layer of precious metal 12 covers base material 11 part surfaces.Layer of precious metal 12 can cover base material 11 surfaces with strip pattern.For instance, the width of a layer of precious metal 12 is 10mm, and the spacing between each striped is 10mm.Such pattern distributes, and can save 50% precious metal raw material cost.With above-mentioned acid copper-containing solution galvanic deposit, be recovered as example equally, during 100% covering precious metal, anodic current density is identical with negative electrode, is 0.5A/dm
2, as covered 50% precious metal by the present embodiment with strip interval mode, anodic current density is brought up to 1A/dm
2, still significantly lower than 2A/dm
2permission anodic current density, also have the potentiality that further reduce precious metal area coverage.
At this, the material of base material 11 can be titanium.Layer of precious metal 12 can be the composite bed of platinum group layer, ruthenium system layer, iridium system layer or platinum, ruthenium, iridium etc.Layer of precious metal 12 can be used any known technique and base material 11 combinations.
In the present embodiment, base material 11 is whole block material.12 of layer of precious metal are that interval covers on complete base material 11, finally form galvanic deposit anode 10.
Fig. 2 illustrates the front view of the galvanic deposit anode of another embodiment of the utility model.Shown in Fig. 2, galvanic deposit anode 20 comprises strip base material 21 and the layer of precious metal 22 of a plurality of separation.Layer of precious metal 22 covers all surfaces of each base material 21.
In the present embodiment, these have covered interval between the strip base material 21 of precious metal and have arranged, fixing by framework 23, in order to form the insoluble anode adapting with electric deposition device shape.The material of framework 23 can be corrosion-resistant, nonconducting engineering plastics.The width and the distance each other that have covered each strip base material 21 of precious metal can be according to allowing the size of anodic current density and the homogeneity of galvanic deposit recovery metal to determine.When base material 21 width are 10mm, when spacing is also 10mm, the embodiment shown in actual effect and Fig. 1 is basic identical.The formed pattern of layer of precious metal 22 of the present utility model is not limited to the strip of above-described embodiment, can also be bulk, circle shape or other shape.
