Problems solved by technology

[0002] At present, my country's circuit board industry is developing rapidly. Because the wastewater produced by circuit board manufacturers often contains a large amount of metal substances with recycling value, and the heavy metals exceed the standard seriously, especially there are a large number of copper ions in the etching solution, its discharge will cause pollution. It brings great harm to the environment, so how to extract copper ions in the etching solution and improve the production efficiency of electrolytic copper is a technical problem in this field, and the traditional electrolytic cell is very single and cannot electrolyze a variety of metals

Abstract

The invention relates to an electrolyser applicable to titanium cathode plates. The electrolyser comprises a electrolyser body, wherein ion exchange membranes are arranged in the electrolyser body and are used for partitioning the electrolyser body into anode chambers and cathode chambers, and a discharging funnel is further arranged at the bottom of the electrolyser body and is connected with the cathode chambers; the titanium cathode plates are arranged between the anode chambers and the cathode chambers; the discharging funnel is connected with a liquid outlet pipe so as to discharge electrolysis waste liquid; and a collection bin which is suitable for collecting precipitated metal is arranged at the bottom of the discharging funnel, and the entrance of the collection bin is connected with the bottom of the discharging funnel. According to the electrolyser, the precipitated metal is collected by the collection bin, so that the precipitated metal can all be collected, the electrolysis operation and the operation collection are separated from each other and are independent from each other, and the electrolysis efficiency is increased.
