Abstract

The invention relates to the technical field of copper waste liquid electrolysis recovery devices, in particular to an electrolysis recovery device for copper-containing waste liquid of a printed circuit board. The electrolysis recovery device comprises a pretreatment unit and an electrolysis unit, wherein the pretreatment unit comprise a header tank, a blow-off pipe and a chemical adding pipe, aheating plate and stirring blades are installed at the bottom of the header tank, the blow-off pipe is connected with the header tank in a penetrating manner, the chemical adding pipe is installed atthe top of the header tank, a nanofiltration membrane is arranged between a concentration cavity and a circulating cavity, the electrolysis unit comprises a tubular electrolytic cell and a power supply, a base is arranged in the tubular electrolytic cell and used for placing an anode metal bar and a cathode metal bar, and the anode metal bar and the cathode metal bar are electrically connected with the power supply to form a closed loop. According to the electrolysis recovery device for the copper-containing waste liquid of the printed circuit board, the problems of lower recovery rate, shortcontact time and low replacement efficiency of the copper-containing waste liquid of the printed circuit board in the prior art are solved, and an electrolysis recovery device has the advantages of high electrolysis efficiency, high recycling material utilization rate and high replacement efficiency.

Description

technical field [0001] The invention relates to the technical field of electrolytic recovery devices for copper waste liquid, in particular to an electrolytic recovery device for printed circuit board copper-containing waste liquid. Background technique [0002] Chemistry is widely used in the production and processing of printed circuit boards with through holes. Its main purpose is to deposit a layer on the non-conductive tomb village through a series of chemical treatment methods, and then thicken it by electroplating to achieve a specific design thickness. , and sometimes even deposited directly to the required thickness by chemical methods. The chemical copper process is through a series of necessary steps to finally complete the deposition of chemical copper. [0003] With the rapid development of the information industry and the popularization of household appliances, the production of printed circuit boards (pcb) in our country shows a trend of rapid growth. At pre...
