Metal silver recovery, some is using generating sulphide precipitation and its various improvement sides that are derived on the basis of method
Method, but there is the shortcomings that being difficult to overcome in the above method, that is, the sulfide precipitation generated will release a large amount of SO2 in calcination
Gas causes the serious pollution to environment, and is mingled with the aggregation caking for hindering silver in calcination too much in precipitating, and often needs
The secondary calcination of secondary separation is wanted, not only waste of energy, but also easily causes the loss of silver.Also have using chemical method, for example, straight using iron plate
Reduction is connect, C, Si in iron plate etc. can keep subsequent processing hard to tackle, using vulcanized sodium high temperature reduction method, need into silver powder
Small iron furnace melting is generally unsuitable for the few waste water for the treatment of capacity, in the vulcanized sodium precipitation method, is restored according to hydrochloric acid and iron plate de-
Sulphur, this is not only reduced directly more one of formality than iron plate, but also due to a solid liquid phase reactor, processing is also cumbersome.
Electrolysis is a kind of method of recycling silver generally used, and the anion for being electrolysed generation is shifted to anode stub, electrolysis
The electrolytic silver of generation is attached to cathode bar, after electrolysis is fully completed, needs electrolyte giving off electrolytic cell, subsequently enter de-
Silver-colored station, the silver-colored method generally use of existing stripping are manually removed, however silver being attached on cathode bar tightly, it is difficult to by it
It takes off, this is undoubtedly increased the labor intensity of worker.
Invention content

Positioned at the lower section of scraper, inlet and liquid outlet are provided on the side wall of electrolytic cell, the water sucking mouth of water pump is connect with liquid outlet.
Described it further includes controller, and the controller is connect with cylinder, motor and water pump.
The vertical setting of graphite rod A and graphite rod B.
The riser is arranged perpendicular to workbench.
The lower section that the liquid outlet is located in the liquid inlet.
The present invention has the following advantages：Silver recovery of the present invention is efficient, can quickly shell the electrolytic silver on graphite rod
From, mitigate labor intensity.
