Background technology
Alkali etching be PCB enterprise produce an indispensable procedure, etching process be copper on wiring board dissolving, precipitation after separate out into brass work, for reclaiming copper, avoid the wasting of resources and heavy metal waste liquor contamination environment.It is lower that alkali etching copper of the prior art reclaims electrolyzer copper recovery utilization rate, and electrolyzer power line substep is more scattered, directly affects electrolytic copper speed; And cupric ion range intervals matching problem in the flow control of mother liquor add-on system and electrolyzer, the cupric ion span of control namely in the flow rate calculation of mother liquor pump and electrolyzer is too wide, causes our institute's electrolysis copper coin purity out not high enough, or affects the weight of copper; And the Recycle design of recycle pump is more single, the degree of mobilization of part liquid medicine can only be solved.Copper rate of the prior art is according to 24 hours electrolyzing copper amounts at about 60-80 kilogram, and the copper purity of institute's electrolysis is not high, does not become monoblock, and fall and can become fragmentary fritter on the ground, economic worth is lower slightly.
Utility model content
The utility model is intended to provide a kind of printed circuit board alkali etching copper being applicable to vertical thionizer to reclaim electrolyzer.
Printed circuit board alkali etching copper in this programme reclaims electrolyzer, comprises housing and rectifier, electrolyzer, cooling pool, etching liquid cell, proportion check point, sub-liquid bath and drawing liquid groove, and electrolyzer connects drawing liquid groove and connecting tube place is provided with the first pump; Cooling zone and sub-liquid flooded zonevvv is divided in described cooling pool; The cooling zone of described electrolyzer and cooling pool is connected with influent stream pipe and outflow tube, and described influent stream pipe place is provided with the second pump; Etching liquid cell pipeline connects cooling zone and pipeline place is provided with the 3rd pump, and described proportion check point connects cooling zone, sub-liquid bath pipeline connecting fluid flooded zonevvv and pipeline place is provided with the 4th pump.
The utility model has the advantages that: electrolyzer is controlled by housing; rectifier protection housing; etching solution is undertaken being delivered to cooling pool by pump; and in electrolyzer, carry out cyclic electrolysis by influent stream pipe and outflow tube, prevent copper ion concentration from will have a strong impact on etching quality more than after a threshold value.
Further, comprise multiple electrolyzer group in described electrolyzer, described electrolyzer group comprises anode graphite and negative electrode steel plate, and the distance of described anode and negative electrode is 8 ~ 10cm.Copper speed optimum distance on the distance that overtesting is such is under the condition that chemical concentration is identical.
Further, described first pump and the second pump are connected with communicating pipe between tubes.By recycle pump and liquid absorbing pump zoarium, realize, in working cycle, liquid medicine is arrived bottom and the two-way mixing in top, reach the well-proportioned substep of liquid medicine cupric ion of electrolyzer in the electrolytic solution, another aspect well solves the heat dissipation problem of electrolytic solution in electrolytic process.
Further, the pipeline place at the 4th pump place is provided with arm, and arm connects described etching liquid cell.The add-on system of mother liquor uses two outlet instead in original single outlet, and the secondary groove of electrolysis is guided in an outlet, and an outlet leads back mother liquor and adds former bucket, utilizes valve to carry out flow control.Be convenient to like this protect pump, avoid the pressure of pump to cross senior general's pump and damage, reuse pump valve can be turned down while needing flow large.
