Environment-friendly efficient copper mine combination leaching device with reverse-cone sieve disc

Abstract

The invention discloses an environment-friendly efficient copper mine combination leaching device with a reverse-cone sieve disc. A combination leaching bucket and a tail gas purifier are connected through a flange. A stirring motor is connected with a cone hood through a hollow shaft and then inserted in the combination leaching bucket. Blades and a liquid inlet are formed in the cone hood. The upper portion of the hollow shaft is provided with air inlets evenly formed along the shaft circumference. A hydraulic plate in the combination leaching bucket is connected with a spiral conveyor on a bottom valve through a shaft. A jacket is arranged outside the tail gas purifier, an intermedium tube is arranged inside the tail gas purifier, and the intermedium tube and a spiral fin barrel form the jacket structure. A whirlcone is arranged at an outlet of the tail gas purifier. Air (oxygen) in the combination leaching bucket is supplemented automatically, quickly and conveniently, the liquid flow mixing effect is perfect and sufficient, and the combination leaching efficiency is quite high; materials are conveniently, reliably and efficiently prevented from deposition and blockage; and the tail gas purifier completes heat transfer and mass transfer efficiently in a multistage manner, the gas-liquid separation effect is remarkably good, ammonia leakage is effectively prevented, automatic environment-friendly and efficient copper mine combination leaching is achieved, and the device has significant application value.

Description

technical field [0001] The invention relates to a green and environment-friendly copper ore high-efficiency compound leaching device with reverse cone sieve disc. Background technique [0002] A considerable part of copper ore in nature exists in the form of copper sulfide. Copper sulfide can form complexes and dissolve in the ammonia solution of suitable concentration, with enough air (mainly oxygen participating in the reaction) to form complexes and dissolve to complete the combination. After leaching and dissolving, solid-liquid separation can be carried out to proceed to the next step. [0003] Therefore, the compound leaching device of copper ore is an indispensable key equipment for the copper production process, but there are two major defects in the existing copper ore chemical combination leaching device, thus restricting the development of copper production technology. One is that the air blowing is not sufficient and inconvenient, the compound leaching speed of ...

AI Technical Summary

Problems solved by technology

One is that the air blowing is not sufficient and inconvenient, the compound leaching speed of copper sulfide is slow and the efficiency is low, it is necessary to add special air blowing equipment, increase equipment investment, and cause unnecessary troubles; second, ammonia is easy to leak, because ammonia It is a highly irritating, volatile, toxic and harmful gas, so it has a great impact on the environment and consumes a lot of ammonia. However, if a closed device is used for the reaction, it is easy to cause safety accidents such as explosions.
