Abstract
The utility model relates to an environment-friendly recovery processing system for PCB (Printed Circuit Board) waste liquor. The system comprises a collecting pool, a filter and a plurality of electrolytic cells which are sequentially connected through a pipeline, wherein a waste liquor pump and an electromagnetic valve are arranged on the pipeline; four negative plates are arranged in each electrolytic cell; a power source for providing power for the electrolytic cells is arranged in the system; the filter is a filter with a replaceable filter element; and a pressure tester is arranged on the pipeline and used for testing the pressure in the pipeline. The environment-friendly recovery processing system for the PCB waste liquor has the advantages that the filter is additionally arranged in front of the electrolytic cells, so that large-particle matters in the waste liquor can be filtered and the impurity content of the waste liquor in the electrolytic cells is greatly reduced; and the pressure tester is additionally arranged on the pipeline, so that whether the filter is blocked or not can be accurately judged and the filter element can be timely replaced.
Description
Technical field
The utility model belongs to the technical field that the PCB waste liquid is recycled, and particularly relates to a kind of PCB waste liquid environmental protection recovery and processing system.
Background technology
PCB, just the printed circuit board (PCB) manufacturing technology is very complicated, a comprehensive very high processing technology.A qualified PCB will have various heavy waste water and organic waste water to discharge in the course of processing through courses of processing such as heavy copper, plating, development, etchings, complicated component, and intractability is bigger.By the utilization ratio of PCB Copper Foil is 30%～40% to calculate, and the copper content in waste liquid, waste water is just considerable so.Calculate (every copper thickness is 35 microns) by 10,000 square metres of dual platens, then the copper content in waste liquid, the waste water just has about 4500 kilograms, and also has many other heavy metal and precious metals.These metals that are present in waste liquid, the waste water just do not discharge as treated, not only caused waste but also polluted environment.
Mostly adopt electrolytic method to reclaim the copper of the inside to the processing of PCB waste liquid in the prior art, but all be directly waste liquid to be introduced electrolyzer to carry out electrolysis in the prior art, a lot of large granular impurities in the waste liquid do not have pre-treatment, influence electrolytic efficiency, impurity wherein also pollutes the environment simultaneously.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of PCB waste liquid environmental protection recovery and processing system to be provided.
The technical solution of the utility model is: a kind of PCB waste liquid environmental protection recovery and processing system; comprise the collecting tank, strainer, the electrolyzer that connect successively by pipeline; its pipeline is provided with waste drains pump, electromagnetic valve; be provided with negative plate in the described electrolyzer; also be provided with the power supply that electric power is provided to electrolyzer in this system, described strainer is the strainer of replaceable cartridge.
Described electrolyzer is several, is provided with four negative plates in each electrolyzer.
Described pipeline is provided with pressure tester, in order to the testing conduit internal pressure.
The beneficial effects of the utility model
This PCB waste liquid environmental protection recovery and processing system; by before electrolyzer, increasing strainer; large particulate matter in the waste liquid can be filtered; thereby reduce the foreign matter content that enters the waste liquid in the electrolyzer significantly; by on pipeline, installing pressure tester additional; can judge accurately whether strainer stops up, can be in time renew cartridge more.
Description of drawings
Fig. 1 is the synoptic diagram of this PCB waste liquid environmental protection recovery and processing system;
1. collecting tanks among the figure, 2. strainer, 3. electrolyzer, 4. waste drains pump, 5. electromagnetic valve, 6. negative plate, 7. pressure tester, 8. power supply.
Embodiment
Embodiment: referring to Fig. 1; among the figure; a kind of PCB waste liquid environmental protection recovery and processing system; comprise the collecting tank, strainer, the electrolyzer that connect successively by pipeline; its pipeline is provided with waste drains pump, electromagnetic valve; be provided with negative plate in the described electrolyzer, also be provided with the power supply that electric power is provided to electrolyzer in this system, described strainer is the strainer of replaceable cartridge.Described electrolyzer is several, is provided with four negative plates in each electrolyzer.Described pipeline is provided with pressure tester, in order to the testing conduit internal pressure.
This system work process: waste drains pump is extracted waste liquid out after starting from collecting tank, enter electrolyzer through the piping strainer of flowing through, strainer stops large granular impurity in the waste liquid, and waste liquid is through behind the electrolytic tank electrolysis, copper in the waste liquid is adsorbed onto on the negative plate, and the copper in the waste liquid is reclaimed; Waste liquid send next process to handle back up to standard discharging after the electrolysis.
Pressure tester is wherein monitored the pressure in the pipeline constantly, in case filter stoppage or arrive work-ing life, its through-current capability reduces, and the reading of pressure tester will rise, and the workman can judge and timely renew cartridge more according to this.
Claims (3)
1. PCB waste liquid environmental protection recovery and processing system; comprise the collecting tank, strainer, the electrolyzer that connect successively by pipeline; its pipeline is provided with waste drains pump, electromagnetic valve; be provided with negative plate in the described electrolyzer; also be provided with the power supply that electric power is provided to electrolyzer in this system, described strainer is the strainer of replaceable cartridge.
2. PCB waste liquid environmental protection recovery and processing system according to claim 1 is characterized in that: described electrolyzer is several, is provided with four negative plates in each electrolyzer.
