The significant components of electrical equipment and electronic product during printed circuit board (PCB), use very general, wherein etching work procedure is the part of proportion maximum in the PCB Production Flow Chart, when etching solution owing to the dissolving material make etching index (comprising speed, lateral erosion coefficient, surface cleaning etc.) when being lower than processing requirement, namely become etching waste liquor too much.
Nowadays the PCB industry etching waste liquor amount of discharging is increases progressively rapidly trend every year, this is so that also more and more higher to the requirement of etching solution recycling equipment, generally speaking, present etching solution recycling equipment exists mostly that efficient is low, cost is high, floor space is large, the problems such as three wastes discharge are arranged.
The utility model content
Problem to be solved in the utility model provides a kind of alkaline etching liquid cyclic regeneration equipment, and is low in order to the etching solution recycling equipment efficient that solves in the past, and cost is high, and floor space is large, the problem that has the three wastes to discharge in the working cycle.
The technical scheme that the utility model provides is: alkaline etching liquid cyclic regeneration equipment, comprise electrolyzer and the temperature controlling groove that links to each other with electrolyzer, the electrolyzer upper end is provided with two parallel upflow tubes that electrolyzer and temperature controlling groove are communicated with, the 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 the temperature controlling groove lower end, also is provided with recycle pump on the circulation tube, and described temperature controlling groove bottom also is provided with the mother liquor pipe.
Described rising pipe is provided with the 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 fully discharged from rising pipe, and this moment, the by-pass valve control I was opened.
Described mother liquor pipe is provided with the by-pass valve control II.The 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 that enters reached the maximum capacity of alkaline etching liquid cyclic regeneration equipment, the closing control valve II got final product, and opened the by-pass valve control II in the time must again adding mother liquor again.
The lower end of described temperature controlling groove also is 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 when cleaning temperature controlling groove, and in alkaline etching liquid cyclic regeneration equipment work process, the opening-closing valve on the blow-off pipe is in closing condition always.
Described alkaline etching liquid cyclic regeneration equipment connection has the PLC automatic control system.The electrolyzer of whole equipment, temperature controlling groove, valve and pump all are connected with the PLC automatic control system, whole equipment all can be by PLC automatic control system remote monitoring all parts state or control its switch, so that whole system is simple to operate, move also more stable.
The utility model has the advantage of: this alkaline etching liquid cyclic regeneration equipment of the utility model design, have the efficient height, cost is low, and floor space is few, without the advantage of any discharging.
