Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a slag discharge port masonry structure that can adjust the discharge height. Background Technology

[0002] In the pyrometallurgical smelting of heavy metals such as copper and nickel, side-blown smelting furnaces and continuous blowing furnaces are key equipment for completing core processes such as ore smelting and impurity separation. Their operational stability and smelting efficiency have a significant impact on the final product quality and production costs. The slag discharge port, as a crucial channel for discharging slag generated during the smelting process, is structurally vital. Traditionally, slag discharge ports often employ a completely fixed structure, meaning the position and dimensions of all components cannot be changed after construction, resulting in a constant discharge height. However, the smelting processes for heavy metals such as copper and nickel are complex, with different smelting stages requiring varying slag discharge height and speed. A completely fixed discharge port cannot flexibly adjust the discharge height to accommodate these changes, making it difficult to precisely control the reaction conditions within the furnace during smelting. This can lead to problems such as poor or excessively rapid slag discharge, affecting metal recovery rates, smelting energy consumption, and the overall lifespan of the furnace, thus hindering the optimization of the smelting process and the improvement of production efficiency. Utility Model Content

[0003] To address the problem of the inability to adjust the slag discharge height in the existing technology, this utility model provides a slag discharge port masonry structure that allows for adjustable discharge height.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A slag discharge port masonry structure capable of adjusting discharge height is provided inside the slag discharge port, comprising a cover plate, side walls, water jackets, a fixed base, and a semi-fixed base; the water jackets are provided around the inner wall of the slag discharge port, and are connected to the water jackets at the bottom of the slag discharge port and the side walls; the fixed base is provided on the water jacket at the bottom of the slag discharge port, and the fixed base is provided with two sets of side walls, which are respectively closely attached to the water jackets on the side walls of the slag discharge port, and the cover plate is provided between the top of the two sets of side walls and the water jacket at the top of the slag discharge port; the semi-fixed base is provided on the fixed base, and is located between the two sets of side walls.

[0006] Furthermore, the sidewall, the fixed base, and the semi-fixed base are all made of refractory materials.

[0007] Furthermore, the gaps between the side wall and the fixed base, and between the side wall and the cover plate, are filled with high-temperature resistant sealing material.

[0008] Furthermore, the high-temperature resistant sealing material is a magnesium-chromium refractory slurry.

[0009] Furthermore, the surface of the water jacket is provided with a high-temperature resistant protective coating.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention provides a slag discharge port masonry structure with adjustable discharge height. By incorporating a semi-fixed base with adjustable brick layers, the slag discharge height can be adjusted, allowing the structure to adapt to the specific requirements of different smelting stages or production conditions. In the initial stages of smelting, appropriately lowering the discharge height ensures a stable molten metal level in the furnace, facilitating complete melting and reaction of the ore. As smelting progresses, the discharge height can be increased promptly based on the slag formation rate and composition changes, ensuring smooth slag discharge and preventing slag accumulation that could hinder the reaction. This effectively optimizes furnace reaction conditions, improves metal recovery, reduces the risk of impurity contamination, and ultimately enhances product quality. This masonry structure requires no large-scale modifications; the slag discharge height can be adjusted simply by increasing or decreasing the number of bricks. This not only reduces equipment downtime and maintenance and modification costs but also improves production efficiency. Attached Figure Description
