Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a continuous blowing slag granulation device. Background Art

[0002] Copper sulfide concentrate is mainly processed by pyrometallurgy, which is divided into three processes: smelting, blowing and refining. With the continuous advancement of pyrometallurgy technology, the hot three-furnace process of "oxygen-enriched side-blowing smelting + multi-gun top-blowing continuous blowing + rotary anode refining" has broad application prospects.

[0003] At present, the traditional treatment methods for blowing slag mainly adopt water quenching and air quenching processes. The water quenching method is widely used in the production of steel, nickel, etc. However, due to the direct contact between water and high-temperature melt, the generated water vapor cannot be dispersed in time, which will cause explosions and pose certain safety hazards. Although the air quenching method can avoid the above problems, the process equipment is bulky, the equipment operation rate is low, the structure is complex, and the cost is high.

[0006] Furthermore, the transmission mechanism includes a motor and a driving wheel, the motor is arranged on the granulation bin, the output shaft of the motor is connected to the driving wheel, the rotating tube is provided with a driven wheel, and the driving wheel and the driven wheel are connected by a belt.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model has the following beneficial effects:

[0014] The motor drives the driving wheel to rotate, and then drives the granulating hopper connected to the rotating tube to rotate. Under the action of centrifugal force, the blowing slag is thrown out, and a certain number of droplets are formed, which are cooled in the air and collide with the wall of the granulating bin. After rebounding, they fall into the granulating bin and settle to the bottom of the granulating bin. The distribution range of the granulation diameter can be adjusted by controlling the speed of the motor.
