Abstract:
    The utility model relates to a closed-loop electrolytic silver-recovery automatic controller, which includes a voltage follower circuit. It is characterized in that: the voltage follower circuit is connected to the pressure regulator whose control terminal joints the microprocessor for controlling the output value of the decomposition potential, and the inlets of the microprocessor is connected with thesampling circuit of the electrolytic current and the decomposition potential. The features are: the controller has closed-loop intelligent controlling function; reflecting the concentration and electrolysis speed of the silver ion in the fixing solutionaccording to the change in the electrolytic current and the decomposition potential; controlling output voltage, output current and switching of the control model by the microprocessor; in the condition of ensureing the quality of recovered silver, and not destroying the component in fixing solution which makes it can be recovered and reused; saving the power and reducing the lost.
