Further to illustrate the present invention to reach the technical means and efficacy that predetermined purpose is taken, below in conjunction with attached drawing
And preferred embodiment, detailed description of specific embodiments of the present invention.
Please refer to Fig. 1, the embodiment of the present invention provides a kind of regenerating alkaline etching liquid and its copper recovery system, including a board
1 and a controller, an electrolysis unit 2 and a bronze medal recycling and processing device 3 are formed on the board 1, and the electrolysis unit 2 is distinguished
It is connected to a waste liquid tank 4 and a regenerated liquid regulating tank 5, the copper recycling and processing device 3 includes being set to 2 a side of electrolysis unit
On a pickling neutralization chamber 31, at least rinsing bowl 32 that is set on 31 side of pickling neutralization chamber and be set to rinsing bowl 32
Primary antibody oxidation trough 33 on side.Specifically, the present embodiment is added in the anti-oxidant slot 33 antioxidant solution, in institute
It states to be added in pickling neutralization chamber 31 and has acid solution, for example, weak sulfuric acid solution, being added in the rinsing bowl 32 has clear water, and
The quantity of the rinsing bowl 32 is two, that is, carries out washing step twice.
The present embodiment carries out Direct Electrolysis to the alkaline etching liquid (etching work procedure generation) in waste liquid tank 4 by electrolysis unit 2,
Obtain cathode plate.Meanwhile subsequent processing is carried out to cathode plate by copper recycling and processing device 3, first cathode plate is put into
In pickling neutralization chamber 31, cathode plate alkaline solution remained on surface is neutralized；Then, cathode plate is put into rinsing bowl
In 32, cathode plate surface is washed；Finally, cathode plate is put into anti-oxidant slot 33, to cathode plate surface
Anti-oxidant treatment is carried out, so that adhering to anti oxidation layer on cathode plate surface, effectively prevent cathode plate oxidizing blackening (non-oxidation
Copper generate), as a result, obtain high-purity, non-oxidation, light cathode plate.
In order to further increase the antioxygenic property of cathode plate, as shown in Figure 2 and Figure 3, the present embodiment is in the antioxygen
Two inner side edge tops of change slot 33 are horizontal respectively an air knife 331, is formed with inside the air knife 331 and is connected to external air blower

3311 opening direction is diagonally downward, preferential, and the opening direction of the bar shaped air outlet 3311 tilts down 30 °.Work as tough cathode
After plate is put into anti-oxidant slot 33, from air blower to the intracavitary air blast of the wind of air knife 331, then blown out by several bar shaped air outlets 3311
High speed winds dry up cathode plate surface, and cathode plate surface is effectively prevent to be oxidized, and antioxygenic property are improved, to improve
The purity and brightness of cathode plate.
In the present embodiment, as best shown in figs. 1 and 4, the electrolysis unit 2 includes several electrolysis being formed on board 1
It slot 21, the anode plate 22 being set in electrolytic cell 21 and is set in electrolytic cell 21 and is located at 22 two sides of anode plate
One cathode plate 23, when electrolysis, copper is formed on 23 surface of cathode plate, forms cathode plate.
It is uniformly distributed and the copper of consistency of thickness in order to be formed in 23 single side surface of cathode plate, in order to subsequent stripping
From the present embodiment is respectively formed with two longitudinal directions being from top to bottom inserted into for 23 end of cathode plate on the inside of 21 both ends of electrolytic cell
Bar shaped slot 211, and this two longitudinal bar shaped slots 211 are distributed on the two sides of 21 end of electrolytic cell, 23 liang of the cathode plate
After end is inserted into longitudinal bar shaped slot 211,23 lateral surface of cathode plate and 21 inner wall of electrolytic cell are mutually close, and close to patch
It closes, it is preferred that it is optimal state that 23 lateral surface of cathode plate, which is contacted with 21 inner wall of electrolytic cell when being adjacent to, then at this time outside cathode plate 23
It is seamless between 21 inner wall of side and electrolytic cell.Since 23 end of cathode plate is inserted into longitudinal bar shaped slot 211, then cathode
Almost without gap between 211 inner wall of 23 end surface of plate and longitudinal bar shaped slot, meanwhile, 23 lateral surface of cathode plate and electrolytic cell
Also almost without gap between 21 inner walls, therefore, between 23 end surface of cathode plate and longitudinal 211 inner wall of bar shaped slot and
Electrolyte liquid medicine is seldom between 21 inner wall of 23 lateral surface of cathode plate and electrolytic cell, almost without being electrolysed that is, at the two positions
Liquid exchange capacity is seldom, even without that is, without the presence of copper ion at the two positions.As a result, in 23 end surface of cathode plate
Long copper is seldom on (on keeping to the side) and 23 lateral surface of cathode plate, or even not long copper, and only (removes on 23 inner surface of cathode plate
End surface) append one layer of copper, and copper is evenly distributed, consistency of thickness, the effective area of copper is big on cathode plate, convenient for subsequent
Copper is removed, the generation of layers of copper surrounding thickness, intermediate thin phenomenon on cathode plate 23 has effectively been prevented.
Meanwhile being put into and taking out for the ease of anode plate 22 and cathode plate 23, as shown in figure 4, the present embodiment is described
Electrolysis unit 2 is all around equipped with a wall 24, is respectively formed on the opposite two sides of the wall 24 with electrolytic cell 21 one by one
Corresponding several pocket sets 241, the pocket set 241 include card slot 2411 and difference position in one be caught in for 22 end of anode plate
In middle 2411 two sides of card slot and the side bayonet slot 2412 that is caught in for 23 end of cathode plate.
As further improvement of this embodiment, electrolyte liquid medicine issues pernicious gas (such as ammonia) to people in order to prevent
Body damages, if as shown in figure 4, the present embodiment bottom in the electrolytic cell 21 offers and is connected with external exhaust fan
Dry tap stomata 212, and bottom is provided with the air inlet pipe 213 being connected with external blower in the electrolytic cell 21, this into
Several air inlets 2131 are offered on tracheae 213.After the completion of electrolysis, after the electrolyte liquid medicine in electrolytic cell 21 is taken away, adopt
The pernicious gas in electrolytic cell 21 is extracted out by aspirating hole 212 with external exhaust fan, meanwhile, air inlet is passed through by external blower
Several air inlets 2131 on pipe 213 bring external ozone in electrolytic cell 21 into, as a result, when operator is close to open shape
When the electrolysis unit 2 of state, the pollution of pernicious gas not will receive.
Meanwhile several interior seal grooves 242 are concavely provided in the wall 24, it is provided in the interior seal groove 242 interior close
Strip of paper used for sealing is equipped with glass cover in one to fit with interior sealing strip in 24 upper cover of wall；On the board 1 and it is located at electrolysis dress
It sets 2 peripheries and is recessed with an external seal slot 11, be provided with external seal strip in the external seal slot 11, on the board 1 and be located at electricity
Solution 2 periphery of device is covered with the outer glass cover to fit with external seal strip.During electrolysis, by interior glass cover, interior close
Strip of paper used for sealing, outer glass cover are combined with external seal strip, are carried out dual-seal to entire electrolysis unit 2, are prevented from generating in electrolytic process
Pernicious gas overflow external, harm is generated to human body, to improve the safety of production.
