Description

technical field [0001] The invention relates to the technical field of hydrometallurgical electrolytic metals, in particular to a fully automatic production system for wet electrolytic metals capable of fully automatic electrolytic metal manganese and zinc. Background technique [0002] The wet electrolysis production process can be divided into four major processes: compounding (leaching), purification, electrolytic deposition, and electrolytic post-treatment, and the electrolytic post-treatment process is further divided into: cleaning, passivation, drying, stripping, polishing, etc. In the electrolytic metal manganese and other electrolytic metal industries, automation devices are used in the cathode plate entry and exit and electrolytic post-treatment processes, such as patent 201210060577.2, which solves the problem of electrolytic manganese and electrolytic zinc cathode plates entering and exiting the cell. Automation; such as patent 201310118379.1, which realizes the ...

Problems solved by technology

These existing technologies still only realize the automation of one process or some steps in one process in electrolytic production, and fail to realize the automation of the two major processes of electrolytic metal deposition and electrolytic post-treatment, and the number of processes to be processed Huge cathode plate, and the mechanical devices of each step have a single function, so there are many devices, and they need to be connected by various manipulators and docking transmission mechanisms. There are many machines, and maintenance is troublesome. Even lasers are used to accurately position the insert board, but it is still impossible to know Whether it will damage the diaphragm bag in the liquid in the tank, there are operational defects

[0003] Wet electrolytic production, the current production line mostly adopts the method of single-slot parallel connection and multi-slot series connection. The scale of a single production line is not large, such as electrolytic manganese, and the output of each production line is more than 10,000 tons. With the expansion of production enterprises and Due to industry access and other reasons stipulated by the state, using this method to seek the expansion of single-line production has potential safety hazards of excessive loop voltage, inconvenient production and operation, and is not conducive to energy conservation and environmental protection.

Patent 201220745182.1 has been improved by implementing multi-tank parallel connection and series-connected tanks, using high-current and low-voltage electrolysis, and the output of a single line can reach 30,000 tons, but it is simply to combine multiple tanks together as one tank. It cannot show advantages in terms of fixed investment and operating costs, and the production and operation are inconvenient, making it difficult to promote and use

[0004] In electrolytic production, the largest energy consumption is electrolytic direct current. Shortening the pole distance and lowering the cell voltage are one means. For example, the pole distance of the same name of electrolytic manganese is reduced from the original 80mm to the current 60mm. For example, the patent 201320207718.9 reduces the pole distance of the same name to 50mm, although the DC power consumption is reduced, it is very inconvenient to operate the cathode plate in and out of the tank. Sometimes the cathode plate will damage the diaphragm bag when the cathode plate enters the tank, and local short circuit is prone to occur during the tank surface management operation
