Description

Semi-permeable formula ion is separated out device

The utility model relates to a kind of semi-permeable formula ion and separates out device, and particularly a kind of ion that is used to separate out the metal ion that the power supply plating uses is separated out device.

Shown in Figure 1 is in the past electro-plating method, most metal all can be used as plated material, but commonly used is nickel, chromium, cadmium, copper, silver, zinc, gold and tin etc., but electric plating method is to be seated in the same electroplating bath 13 by plated item 11 and electrolytic metal 12 and to place suitable electrolyte 14, but electrolytic metal 12 is an anode 15, by plated item 11 is negative electrode 16, this electrolyte 14 is the solution of plated metal salt, used electric current is the direct current of 6-24 volt, during energising, metal ion in the electrolyte 14 is deposited on by on plated item 11 surfaces, and the metal ion that is lost in the electrolyte 14, then the metal material by anode replenishes.

Above-mentioned electro-plating method is to dissociate and the reducing metal ion in same electroplating bath 13,, the electrolytic metal of this anode 15 discharges less metal ion but can consuming after 12 use a period of times gradually, and the concentration of metal ions in this electrolyte 14 is reduced, but therefore need to replenish the electrolytic metal 12 of this anode 15.Most are seated in the electroplating bath 13 together by plated item 11 on making, can be different by the distance of the anode 15 in the same groove of plated item 11 distances because of each, and make by the thickness of coating on the surface of plated item 11 inhomogeneous, in addition, but it is electronegative by plated item 11 varying in size or differ too much with respect to the electrolytic metal electrode of positively charged in the same groove, in electroplating bath 13, produce the point discharge effect easily, also can cause by the uneven thickness of plated item 11 overlay coatings.

Main purpose of the present utility model provides a kind of semi-permeable formula ion and separates out device, and it is that metal ion is separated out from electrolyte, and has the effect that abundant circulation provides continuously the metal ion of automatic plating use.

Second purpose of the present utility model provides a kind of uniform semi-permeable formula ion of effect of plating that makes and separates out device.

Principal character of the present utility model be mat between anode and negative electrode every establishing an electrodialysis film, anode is immersed in the electrolyte, negative electrode then is immersed in the conducting solution, this electrodialysis film has the characteristic that does not allow metal ion pass through and can conduct electricity, and keep the electric connection of anode and negative electrode, therefore make anode continue release metal ions in electrolyte, make electrolyte continue to charge into metal ion, and reach the effect of precipitating metal ion.

Semi-permeable formula ion of the present utility model is separated out device, it is characterized in that: comprise an electrodialysis film, an ion is separated out groove, but an electrolytic metal and a conductive electrode, described electrodialysis film has the characteristic that does not allow metal ion pass through and can conduct electricity, described ion is separated out groove and is divided into an electrolytic cell and a conductive trough by described electrodialysis film, suitable electrolyte is arranged in the described electrolytic cell, conducting solution is then arranged in the described conductive trough, but described electrolytic metal is immersed in described ion and separates out in the electrolyte of electrolytic cell in the groove, and electrical connection anode, described conductive electrode is immersed in described ion and separates out in the conducting solution of conductive trough in the groove, and is electrically connected negative electrode.

But described ion is separated out the metal salt solution that the electrolyte of groove is electrolytic metal.

The conducting solution that described ion is separated out groove is the dilute acid soln with electric conductivity.

But described electrolytic metal is a metal derby packs in the nonexpendable conduction hoop and is immersed in described ion and separate out in the electrolyte of groove, makes described conduction hoop be electrically connected anode.

Described electric conductivity hoop is to have electric conductivity and titanium alloy material that can electrolysis.

Effect of the present utility model is, by establishing an electrodialysis film at interval at anode and negative electrode, anode is immersed in the electrolyte, negative electrode then is immersed in the conducting solution, has the characteristic that does not allow metal ion pass through and can conduct electricity because of this electrodialysis film, and keep the electric connection of anode and negative electrode, therefore make anode continue release metal ions in electrolyte, make this electrolyte continue to charge into metal ion, reach the effect of precipitating metal ion, just can fully be provided for electroplating the reduction use so contain the electrolyte of metal ion.

Below by most preferred embodiment and accompanying drawing semi-permeable formula ion of the present utility model is separated out device and be elaborated, in the accompanying drawing:

Fig. 1 is the schematic diagram of electro-plating method in the past.

Fig. 2 is the preferred embodiment schematic diagram that semi-permeable formula ion of the present utility model is separated out device.

As shown in Figure 2, but the utility model comprises an electrodialysis film 2, ion separates out groove 3, an electrolytic metal 4 and a conductive electrode 5.

This electrodialysis film 2 has the characteristic that does not allow metal ion pass through and can conduct electricity, and is located at this ion and separates out in the groove 3, and this ion is separated out groove 3 separates and be two parts.

This ion is separated out groove 3 and is divided into an electrolytic cell 31 and a conductive trough 32 by this electrodialysis film 2, in this electrolytic cell 31 suitable electrolyte 33 is arranged, in this conductive trough 32 conducting solution 34 is arranged then, but this electrolyte 33 is metal salt solutions of electrolytic metal 4, and this conducting solution 34 is the dilute acid solns with electric conductivity.

But should electrolytic metal 4 be to pack in the nonexpendable conduction rim 41 and immerse this ion and separate out in the electrolyte 33 of electrolytic cells 31 in the groove 3 with metal derby, and make this conduction hoop 41 be electrically connected anode 61, this electric conductivity hoop 41 has electric conductivity and non-expendable, and be can electrolysis the titanium alloy material.

This conductive electrode 5 is immersed in this ion and separates out in the conducting solution 34 of conductive trough 32 in the groove 3, and is electrically connected negative electrode 62.

By above-mentioned structure, but the electrolytic metal 4 that is electrically connected anode 61 can continue release metal ions in electrolyte 33, because of potential difference, the metal ion that dissociates can move towards the electrode 5 of negative electrode 62, but the metal ion that dissociates in this electrolyte 33 can be separated on the conductive electrode 5 that can not be deposited on negative electrode 62 by this electrodialysis film 2, this electrodialysis film 2 has the characteristic that does not allow metal ion pass through and can conduct electricity, and keep the electric connection of anode 61 and negative electrode 62, but the electrolytic metal 4 that makes anode 61 continues electrolysis and goes out metal ion in this electrolyte 33, make this electrolyte 33 continue to produce metal ion, but being extracted out, these electrolyte 33 mat circulating pumps that contain metal ion provide the plating reduction required metal ion, and after utilizing metal ion to dissociate in this electrolyte 33, extraction is used for electroplating again, and metal ion is distributed in this electrolyte 33, plating reaches effect of uniform.

Embodiment shown in Figure 2 is of the present utility model illustrating, and this hoop and electrolytic metal can be accelerated because of needs and be arranged to soak to be located in the electrolyte, and the electrolyte that contains metal ion in order to a large amount of generations is to cooperate industrial demand.
