Gas-filling temperature-raising leaching tank

Abstract

The invention discloses a gas-filling temperature-raising leaching tank, and relates to improvement of a leaching tank structure during gas-filling and leaching process of hydrometallurgy. The leaching tank is characterized in that a feed pipe of the leaching tank is opposite to middle portions of stirring blades, a stirring device on a stirring shaft comprises an upper layer and a lower layer of the stirring blades and stirring paddles, a structure of a chlorine gas feed device comprises a chlorine gas inlet pipe and a communicating pipe of an outer pipe, the communicating pipe is in shape like a Chinese character 'bo', the stirring shaft is arranged deviating from the perpendicular axis of the leaching tank, and the structure of a heating gas inlet pipe comprises inner layer titanium steel, a stainless steel pipe layer wrapped outside the inner layer titanium steel, and a rubber pipe layer wrapped outside the stainless steel pipe. The leaching tank can effectively improves anti-swing intensity, prevents a heating shaft from being broken, is long in period, improves safety of operation equipment, effectively ensures leaching temperatures of materials, improves dissolving velocity of the solid particles, accelerates leaching reaction, prolongs use period by 20 times, and is safe and reliable.

Description

technical field [0001] An air-entraining and heating leaching tank relates to an improvement of the structure of the leaching tank used in the air-entraining leaching process of hydrometallurgy. Background technique [0002] At present, the main method used in the process of processing complex nickel materials such as nickel cobalt sulfide, nickel carbonate, and nickel hydroxide is to leaching the material with chlorine gas, and then sending the produced nickel chloride solution to the nickel system to produce electrolytic nickel products. Most of the chlorine gas leaching process adopts vertical mechanical stirring leaching tank with strong stirring ability, which is suitable for chlorine leaching production process. [0003] There are still some deficiencies in the vertical mechanically stirred leaching tank. The feeding device of the vertical mechanically stirred leaching tank is usually a feeding pipe that penetrates vertically through the top cover of the vertical mecha...

AI Technical Summary

Problems solved by technology

During use, the heating pipe vibrates violently due to the internal and external impact of the steam in the pipe and the ore slurry in the tank. Due to insufficient anti-sway strength, the heating pipe often breaks, the service life is short, and it causes great damage to the operating equipment. security risks
