Description

Technical Field

[0001] The utility model relates to the field of copper slag processing, and more specifically to a slow cooling device for copper slag. Background Art

[0002] Copper slag is the slag produced in the copper smelting process and is a type of non-ferrous metal slag. The waste slag discharged from copper smelting using the reverberatory furnace method is reverberatory furnace copper slag, and the waste slag discharged from copper smelting using the blast furnace method is blast furnace copper slag. For every ton of copper smelted, the reverberatory furnace method will produce 10-20 tons of slag, and the blast furnace method will produce 50-100 tons of copper slag. Copper slag and quenching slag can be mixed with lime and compacted to form a highway base. Using air-cooled copper slag as railway ballast has a good effect. The molten copper slag can also be directly cast into dense and hard copper slag masonry, or the copper slag can be placed in a recovery room for oxidation and melting, and then treated by a reduction method to recover granular copper.

[0003] For example, the announcement No. CN117660769A discloses a copper slag slow cooling device and a slow cooling process, wherein the slow cooling device has a heat preservation plate disposed on the outer wall of the cylinder, and an interlayer cavity is formed between the heat preservation plate and the outer wall of the cylinder; the heat preservation plate and the cylinder are connected by a rib plate and a fixing plate; a water guide plate is disposed on the upper end of the heat preservation plate, a gap is disposed between the water guide plate and the outer wall of the cylinder, and the water guide plate is disposed obliquely so that the guided water flows toward the outer wall of the cylinder; in the air cooling section, the water guide plate is used to hinder the air circulation in the interlayer cavity; The copper slag slow cooling device process includes an air cooling section and a water cooling section. The outer wall of the slag bag in the air cooling section is provided with an insulation plate, and the insulation plate and the cylinder form at least one layer of interlayer cavity; in the air cooling section, the interlayer cavity is used to hinder the air flow and slow down the heat loss rate of the slag bag; in the water cooling section, the overflowing water enters the interlayer cavity and flows down along the outer wall of the cylinder to the lower ring. The insulation plate and the interlayer cavity are used to limit the water flow to flow downward along the outer wall of the cylinder, so that the water flow does not separate from the outer wall of the cylinder or drip under the action of gravity.

[0004] It can be seen from the above-mentioned public scheme that currently copper slag is mostly directly piled up for processing during slow cooling. The copper slag inside the copper slag pile is not easy to be slowly cooled during the slow cooling process, which brings many disadvantages to the processing work. At the same time, the blowing device during the slow cooling process blows the wind concentratedly into the slow cooling equipment, which is not easy to disperse the blowing work on the copper slag.
