Description

Technical Field

[0001] This utility model relates to the field of copper smelting furnace technology, specifically to an environmentally friendly refractory material furnace lining structure for copper smelting. Background Technology

[0002] A copper smelting furnace is a device used to smelt copper ore, concentrate or other copper-containing materials at high temperatures to extract metallic copper. The refractory lining of a copper smelting furnace is usually made of refractory bricks.

[0003] For example, China Utility Model Patent No. 202122527478.8 provides a "lining structure for a crude copper pyrometallurgical refining furnace". This patent includes a furnace shell, a permanent bottom surface, refractory castable, spinel refractory bricks and refractory mud layer. The permanent bottom surface is provided on the inner side of the furnace shell. Refractory castable is filled between the permeable bricks and the refractory bricks, which increases the refractory resistance of the outer lining and reduces the cracking of the furnace body. The addition of zirconium corundum refractory bricks increases the high-temperature strength of the lining structure and improves the refractory resistance of the lining and the furnace body.

[0004] Although the aforementioned documents have solved the problem of poor refractory and crack resistance of existing copper smelting furnace lining structures, they still have the disadvantage of inconvenient repair of the furnace lining structure. The furnace lining structure adopts a fixed connection method, and when cracks and damage occur during long-term use, the repair work is difficult. Therefore, an environmentally friendly refractory material furnace lining structure for copper smelting is proposed here. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly refractory furnace lining structure for copper smelting, which has the advantage of being easy to repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly refractory material furnace lining structure for copper smelting, comprising a furnace body, an installation frame fixedly connected to the inner wall of the furnace body, a locking block movably connected to the inner cavity of the installation frame, a first refractory wall fixedly connected to the side of the locking block away from the installation frame, semi-circular grooves provided on both sides of the first refractory wall, a semi-circular block movably connected to the inner cavity of the semi-circular groove, a second refractory wall fixedly connected to the side of the semi-circular block away from the semi-circular groove, the first refractory wall and the second refractory wall being made of the same material, the first refractory wall comprising a base material layer, a high-temperature resistant layer fixedly connected to the inner surface of the base material layer, a refractory layer fixedly connected to the inner surface of the high-temperature resistant layer, and a corrosion-resistant layer fixedly connected to the inner surface of the refractory layer.

[0008] As a preferred embodiment, the refractory layer is made of spinel refractory brick, and the corrosion-resistant layer is made of high-alumina brick.

[0009] As a preferred embodiment, a refractory reinforcement layer is fixedly connected to one side of both the first refractory wall and the second refractory wall, and the material of the refractory reinforcement layer is refractory mortar.

[0010] As a preferred embodiment, both the inner surfaces of the first and second fire-resistant walls are provided with grooves, and the top of the inner cavity of the groove is provided with a hook groove.

[0011] As a preferred embodiment, the inner wall of the furnace body is fixedly connected with an isolation strip, the isolation strip being made of high-alumina permeable brick.

[0012] As a preferred embodiment, the front of the mounting frame is movably connected to a reinforcing plate via a plug rod, and the other side of the bottom of the reinforcing plate is movably connected to the surface of the card block via a plug rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the installation frame, the locking block, the first fire-resistant wall and the second fire-resistant wall, allows repair workers to use special tools to hook the first fire-resistant wall and the second fire-resistant wall when cracks and wear occur during long-term use and repair is required.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0024] Please see Figures 1-5 As shown, this utility model provides an environmentally friendly refractory furnace lining structure for copper smelting, including a furnace body 1. An installation frame 2 is fixedly connected to the inner wall of the furnace body 1. A locking block 3 is movably connected to the inner cavity of the installation frame 2. A first refractory wall 4 is fixedly connected to the side of the locking block 3 away from the installation frame 2. Semicircular grooves 5 are provided on both sides of the first refractory wall 4. A semicircular block 6 is movably connected to the inner cavity of the semicircular groove 5. A second refractory wall 7 is fixedly connected to the side of the semicircular block 6 away from the semicircular groove 5. The first refractory wall 4 and... The second fire-resistant wall 7 is made of the same material. The first fire-resistant wall 4 includes a base material layer 401. A high-temperature resistant layer 402 is fixedly connected to the inner surface of the base material layer 401. A fire-resistant layer 403 is fixedly connected to the inner surface of the high-temperature resistant layer 402. A corrosion-resistant layer 404 is fixedly connected to the inner surface of the fire-resistant layer 403. Repair workers can use special tools to hook the first fire-resistant wall 4 and the second fire-resistant wall 7, remove the reinforcing plate, and then lift the first fire-resistant wall 4 or the second fire-resistant wall 7 upwards for disassembly and repair.

[0025] This technical solution incorporates the installation frame 2, the clip 3, the first refractory wall 4, and the second refractory wall 7. The first refractory wall 4 and the second refractory wall 7 are fixed to the inner wall of the furnace body 1 using a detachable fixing structure, which facilitates disassembly and repair when cracks or wear occur. Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the substrate layer 401 is made of asbestos cement, the high-temperature resistant layer 402 is made of zirconium corundum refractory brick, the refractory layer 403 is made of spinel refractory brick, the corrosion resistant layer 404 is made of high alumina brick, and a refractory reinforcing layer 8 is fixedly connected to one side of both the first refractory wall 4 and the second refractory wall 7. The refractory reinforcing layer 8 is made of refractory mortar.

[0027] The main purpose of adopting the above technical solution is to improve the refractory and corrosion resistance of the furnace lining refractory material. Example 3:

[0028] Based on Embodiment 2, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the inner surfaces of the first refractory wall 4 and the second refractory wall 7 are both provided with grooves, and the top of the inner cavity of the groove is provided with a hook groove. The inner wall of the furnace body 1 is fixedly connected with an isolation strip 9, which is made of high-alumina permeable brick. The front of the mounting frame 2 is movably connected with a reinforcing plate through a plug rod, and the other side of the bottom of the reinforcing plate is movably connected to the surface of the card block 3 through a plug rod.

[0029] The above technical solution is mainly adopted to facilitate the removal of the first refractory wall 4 and the second refractory wall 7 using a tool such as a hook, thereby reducing the probability of furnace lining cracking and improving the refractory performance of the furnace lining. One end of the tool is inserted into the hook groove at the top of the inner cavity of the groove, and the first refractory wall 4 and the second refractory wall 7 are lifted upwards and removed using the tool. Refractory castable is filled between the isolation strip 9 and the first refractory wall 4 and the second refractory wall 7, which increases the refractory performance of the outer perimeter of the lining and reduces the possibility of internal cracking. The inserts on both sides of the bottom of the reinforcing plate are inserted into the inner cavities of the locking block 3 and the mounting frame 2, respectively, thereby strengthening the locking stability of the locking block 3 in the inner cavity of the mounting frame 2.

[0030] The working principle of this utility model is as follows: When the first refractory wall 4 and the second refractory wall 7 crack and wear during long-term use and need repair, the repair worker inserts one end of a hook-like tool into the hook groove at the top of the inner cavity of the groove, and uses the tool to lift the first refractory wall 4 and the second refractory wall 7 upwards for disassembly and repair. During use, the furnace lining can improve its performance through the base material layer 401, the high-temperature resistant layer 402, the refractory layer 403, the corrosion-resistant layer 404, and the refractory reinforcement layer 8. Specifically, asbestos cement is a commonly used refractory material with excellent acid resistance in furnace walls and furnace bottoms. Zirconia-corundum refractory bricks are high-quality refractory materials with excellent refractory properties. Their main components include alumina and zirconium oxide, both of which have high melting points, enabling zirconia-corundum refractory bricks to maintain stable performance in high-temperature and even ultra-high-temperature environments. Spinel refractory bricks are refractory materials produced using magnesium aluminate spinel as the main raw material. They have excellent properties such as high melting point, good thermal shock stability, and resistance to slag erosion. High-alumina bricks are very important refractory materials that can withstand corrosion and wear from many strong acids and high-temperature environments, and can withstand extremely high pressure and temperature.
