Description
Technical Field
The utility model belongs to the technical field of nonferrous metal electrolysis, and particularly relates to an automatic short-circuit switching device for an electrolytic cell bus and an electrolytic cell.
Background
The non-ferrous metal electrolysis production industry can involve direct current short-circuit operation, and the nickel electrolysis industry generally adopts nickel sulfide soluble anode diaphragm electrolysis technology, and the technology can only realize single-tank short-circuit during nickel electrolysis discharging operation due to the limitations of anode plate metallization degree (nickel sulfide anode metallization degree is low, nickel is about 70%), electrolyte circulation mode (cathode and anode liquid are separated by diaphragm bags) and the like, and a manual short-circuit device is used. The device is used for years in the nickel electrolysis industry, is relatively crude, and has the following problems in the use process:
1. the transverse electric device compresses the short-circuit copper bar arranged on the short-circuit switch device with a groove head (groove tail) bus in a spiral screw mode, and the direct-current bus short circuit is realized. The short circuit effect can be influenced by the difference of the force of operators, if the short circuit copper bar is in poor contact with the bus at the groove head (the groove tail), the short circuit effect is poor, the copper bus at the position can generate heat, and scalding accidents can be caused when the temperature is high.
2. When the short-circuit switches at the two ends (the tank head and the tank tail) of the electrolytic tank need to be operated in a short-circuit mode, operators need to operate one by one, synchronous opening and closing cannot be achieved, and the phenomenon that a bus is closed is easy to generate heat is caused.
3. When the nickel sulfide anode has passivation phenomenon, the tank voltage rises sharply in a short time, and in this case, strong electric arc is likely to occur when the short-circuit device is used, so that certain safety risk exists in the short-circuit operation; meanwhile, in the case of emergency short circuit, otherwise, direct current open circuit occurs due to passivation of the nickel sulfide anode (the nickel sulfide anode is not conductive in the state), current impacts silicon rectification, so that the whole electrolysis system is powered off, and extremely serious production accidents are caused.
