A device for extracting silver from silver-containing wastewater

Abstract

The invention discloses silver-containing wastewater silver extracting equipment and relates to the technical field of wastewater processing equipment. The silver-containing wastewater silver extracting equipment comprises a case. A stirring shaft is rotationally connected with the bottom of the inner wall of the case through a bearing seat. The top end of the stirring shaft penetrates through thecase and extends to the top of the case. The end, extending to the top of the case, of the stirring shaft is provided with a transmission worm wheel. A rotary rod is rotationally connected with the part, located on one side of the stirring shaft, of the top of the case through a supporting plate. One end of the rotary rod penetrates through the supporting plate and extends to one side of the supporting plate. Through the silver-containing wastewater silver extracting equipment, the stirring effect is greatly improved, the stirring efficiency is improved, people do not need spend much time tostir, the labor intensity of people is relieved, the working efficiency of people is improved, a complete stirring reaction of a displacer and silver-containing wastewater is conducted rapidly and efficiently, and thus the silver extraction operation by people is greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment equipment, in particular to equipment for extracting silver from silver-containing waste water. Background technique [0002] According to statistics, more than 85% of the precious metals used in the world are recycled and reused. A few days ago, the annual profit of electronic waste disposal enterprises in the United States has reached 25 million US dollars and 30 million US dollars. According to statistics, it costs about US$300,000 to mine 1 ton of silver, but only US$10,000 to recover 1 ton of silver; it costs US$250-300 to mine 1 ounce of gold, but only US$100 to recover 1 ounce of gold. For another example, if you recycle the waste batteries in old mobile phones and accumulate them to 1 ton, you can extract 100 grams of gold from them; while ordinary gold-bearing ore (sand) can only extract a few grams of gold per ton, and most of them do not exceed 1 ton. Dozens of grams of ...
