Background technology
Improvements along with electron trade, China's wiring board industry development is also broad-based recovery thereupon, according to < < 2009-2012 Chinese printing circuit-board industry developing foreground forecast analysis report > >, point out, China will become PCB industrial base the biggest in the world in recent years, accounts at present 30% left and right of world market.Simultaneously, Suining, Sichuan has been " southwestern circuit card (PCB) the industry manufacture base " that country examines at present, the PCB industry giants such as two places, Chongqing of Sichuan Founder Electronic, Foxconn's electronics enter, and coastal a large amount of circuit board plant is moved to the interior, and PCB industry will welcome huge business opportunity.
The significant components of electrical equipment and electronic product during printed circuit board (PCB), apply very general, wherein etching work procedure is a part for proportion maximum in PCB Production Flow Chart, when etching solution makes etching index (comprising speed, lateral erosion coefficient, surperficial cleanliness etc.) lower than processing requirement too much due to the material dissolving, become etching waste liquor.
Nowadays the etching waste liquor amount that PCB industry is discharged is every year and increases progressively rapidly trend, this makes the requirement of etching solution recycling equipment also more and more higher, generally speaking, current etching solution recycling equipment exists that efficiency is low, cost is high, floor space is large, have the problems such as three wastes discharge mostly.
Summary of the invention
Problem to be solved by this invention is to provide a kind of alkaline etching liquid cyclic regeneration equipment, and low in order to the etching solution recycling equipment efficiency solving in the past, cost is high, and floor space is large, the problem that has the three wastes to discharge in working cycle.
Technical scheme provided by the invention is: alkaline etching liquid cyclic regeneration equipment, comprise electrolyzer and the temperature controlling groove being connected with electrolyzer, electrolyzer upper end is provided with two parallel upflow tubes that electrolyzer is communicated with temperature controlling groove, electrolyzer lower end is provided with circulation tube and rising pipe, circulation tube one end is communicated with electrolyzer, the other end is communicated with temperature controlling groove lower end, is also provided with recycle pump on circulation tube, and described temperature controlling groove bottom is also provided with mother liquor pipe.
Described rising pipe is provided with by-pass valve control I at the exit end of electrolyzer.Electrolyzer by-pass valve control I when work is closed, and the sub-liquid after inner mother liquor electrolysis is completely discharged from rising pipe, and now by-pass valve control I is opened.
Described mother liquor pipe is provided with by-pass valve control II.Mother liquor pipe is the pipeline that mother liquor enters temperature controlling groove, when mother liquor enters alkaline etching liquid cyclic regeneration equipment, when its capacity entering reaches the maximum capacity of alkaline etching liquid cyclic regeneration equipment, closing control valve II is opened by-pass valve control II in the time must rejoining mother liquor again.
The lower end of described temperature controlling groove is also provided with blow-off pipe, and blow-off pipe is provided with opening-closing valve, and described blow-off pipe is communicated with rising pipe.The effect basic fixed position of blow-off pipe is the sewage flow pipeline while cleaning temperature controlling groove, and in alkaline etching liquid cyclic regeneration equipment work process, the opening-closing valve on blow-off pipe is always in closing condition.
Described alkaline etching liquid cyclic regeneration equipment connection has PLC automatic control system.The electrolyzer of whole equipment, temperature controlling groove, valve and pump are all connected with PLC automatic control system, whole equipment all can be by PLC automatic control system remote monitoring all parts state or control its switch, make whole system simple to operate, move also more stable.
The invention has the advantages that: this alkaline etching liquid cyclic regeneration equipment of the present invention's design, there is efficiency high, cost is low, and floor space is few, without the advantage of any discharge.

Embodiment
Embodiment 1
Referring to Fig. 1, technical scheme provided by the invention is: alkaline etching liquid cyclic regeneration equipment, comprise electrolyzer 1 and the temperature controlling groove 3 being connected with electrolyzer 1, electrolyzer 1 upper end is provided with two parallel upflow tubes 2 that electrolyzer 1 is communicated with temperature controlling groove 3, electrolyzer 1 lower end is provided with circulation tube 8 and rising pipe 6, and circulation tube 8 one end are communicated with electrolyzer 1, and the other end is communicated with temperature controlling groove 3 lower ends, on circulation tube 8, be also provided with recycle pump 9, described temperature controlling groove 3 bottoms are also provided with mother liquor pipe 4.
Above-mentioned rising pipe 6 is provided with by-pass valve control I 10 at the exit end of electrolyzer 1.
Above-mentioned mother liquor pipe 4 is provided with by-pass valve control II 7.
The lower end of above-mentioned temperature controlling groove 3 is also provided with blow-off pipe, and blow-off pipe is provided with opening-closing valve 5, and described blow-off pipe is communicated with rising pipe.
Above-mentioned alkaline etching liquid cyclic regeneration equipment connection has PLC automatic control system.
In use, mother liquor enters in temperature controlling groove 3 by mother liquor pipe 4, by the pipe structure for cooling in temperature controlling groove 3, be down to suitable temp, by circulation tube 8 cocycle pump 9 effects, enter electrolyzer 1 again, in electrolyzer 1, be provided with negative plate and positive plate, by electrolytic action, the cupric ion electrolytic reduction in mother liquor is become to copper and is adsorbed on negative plate, the mother liquor after electrolysis is sub-liquid, and sub-liquid is discharged and entered in subsequent processing again by rising pipe 6.
In mother liquor, copper ion concentration is at 150-170g/l, best electrolysis point is 30g/l left and right, so the content of copper ion in electrolyzer 1 must be controlled at 30g/l, guarantee electrolytic efficiency, when being worth lower than this, just by mother liquor pipe 4, increase the inlet of mother liquor, now the capacity of electrolyzer 1 is excessive is back in temperature controlling groove 3 by upflow tube 2, guarantees can reach best electrolysis effectiveness in electrolyzer 1.
