Description

Technical Field

[0001] The utility model relates to the technical field of mining and metallurgy equipment, in particular to a self-sintering device for a submerged arc furnace. Background Art

[0002] A submerged arc furnace, also known as an electric arc furnace or a resistance furnace, is mainly used for reducing and smelting ores, carbonaceous reducing agents, solvents and other raw materials, and mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicomanganese alloy, etc., which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide;

[0003] In the prior art, a submerged arc furnace is mainly used for reducing and smelting ores, carbonaceous reducing agents, solvents and other raw materials. The self-sintering device in the submerged arc furnace is also called a self-baking electrode. The self-baking electrode is made of anthracite, coke, asphalt and tar as raw materials, and electrode paste is made at a certain temperature. Then the electrode paste is filled into the electrode shell already installed on the electric furnace and sintered into shape. Because of its simple process and low cost, the self-baking electrode is widely used in ferroalloy electric furnaces, calcium carbide furnaces, etc., so it is the main structure in the submerged arc furnace. However, during the use of the existing self-sintering device in the submerged arc furnace, a lifting system is needed to lift the self-sintering device. Since the temperature of the self-sintering device is relatively high after use, it needs to be very stable during the lifting process, otherwise accidents are very likely to occur. Therefore, we propose a self-sintering device for a submerged arc furnace. Summary of the Invention

[0027] As Figures 1-3 shown, the present utility model provides a technical solution: a self-sintering device for a submerged arc furnace, including a self-sintering device body 1 and a submerged arc furnace body 2. The self-sintering device body 1 is inserted into the interior of the submerged arc furnace body 2 and extends upward. A lifting ring 3 is welded near the bottom of the periphery of the self-sintering device body 1. A circular lifting ring 4 is clamped at the bottom of the lifting ring 3, and the inner diameter of the lifting ring 4 is the same as that of the lifting ring 3. Connecting plates 5 are symmetrically welded on both sides of the lifting ring 4. At the ends of the connecting plates 5 far from the lifting ring 4, screw rod sliders 6 are fixedly connected. Lifting seats 7 are installed on the peripheries of the screw rod sliders 6. Linear guide rails 8 are provided on the opposite side surfaces of the lifting seats 7 and around the screw rod sliders 6. The linear guide rails 8 can effectively limit the screw rod sliders 6 so that they can only move up and down reciprocally, thereby being able to stably lift the self-sintering device body 1 stably. And the screw rod sliders 6 are fixedly connected to the linear guide rails 8. A screw rod 9 is rotatably connected inside the linear guide rails 8 and on the inner side of the screw rod sliders 6, and the screw rod 9 intersects with the screw rod sliders 6 in a threaded manner. Embodiment 2

[0028] As Figures 1-3 shown, an upper layer plate 71 is fixedly connected to the bottom of the lifting seat 7 and around the self-sintering device body 1, and a lower layer plate 72 is fixedly connected to the periphery of the submerged arc furnace body 2. Both the upper layer plate 71 and the lower layer plate 72 are made of concrete by casting, which can effectively install and fix the self-sintering device body 1 and the submerged arc furnace body 2.

[0029] On both sides of the lifting seat 7, stabilizing plates 73 are symmetrically and fixedly connected. On the top of the stabilizing plates 73, fixing members 74 are symmetrically and fixedly connected. The fixing members 74 penetrate through the stabilizing plates 73 and are fixedly connected to the upper layer plate 71, which can effectively fix the lifting seat 7.

[0030] On the top of the lifting seat 7, dust-proof boxes 75 are fixedly connected. On the top of the dust-proof boxes 75, heat dissipation louvers 76 are fixedly connected, which can effectively prevent dust from entering the driving motor 77 while not affecting its heat dissipation.

[0031] Inside the dust-proof box 75, a driving motor 77 is installed. The driving motor 77 is fixedly connected to the lifting seat 7, and the output end of the driving motor 77 penetrates through the lifting seat 7 and is fixedly connected to the lead screw 9 inside the linear guide 8. Through the driving motor 77, power can be effectively provided for the lead screw 9, and the driving motor 77 drives the lead screw 9 to rotate very stably, so that the lifting process is also very stable.

[0032] At the bottom of the connecting plate 5, triangular support blocks 51 are fixedly connected. The support blocks 51 are fixedly connected to the lead screw slider 6, and the support blocks 51 can effectively improve the support, making the connection more stable.

[0033] The self-sintering device body 1 includes an electrode shell 11, and the inside of the electrode shell 11 is filled with electrode paste 12.

[0034] Symmetrically arranged feeding windows 21 are provided on the periphery of the submerged arc furnace body 2, and the feeding windows 21 are communicated with the inside of the submerged arc furnace body 2, which is convenient for feeding.

[0035] The working process of the present utility model: When using a submerged arc furnace self-sintering device for lifting the self-sintering device, first, the driving motor 77 will work. When the driving motor 77 works, its output end will drive the lead screw 9 inside the linear guide 8 to rotate. When the lead screw 9 rotates, the lead screw slider 6 that intersects with the lead screw 9 in a threaded manner will slide inside the linear guide 8. The linear guide 8 is in a straight state, so that the lead screw slider 6 can only move back and forth without deviation, so it is very stable. When the lead screw slider 6 slides up or down, it will drive the connecting plate 5 to move synchronously. At the same time, the support block 51 also supports the connecting plate 5 to improve the connection stability. At the same time, when the connecting plate 5 moves, it will drive the lifting ring 4 to move. When the lifting ring 4 moves, it will make the lifting ring 3 that is clamped with it move synchronously. The lifting ring 3 will drive the self-sintering device body 1 to move up or down, so as to insert into the inside of the submerged arc furnace body 2 or take out from the inside of the submerged arc furnace body 2. Through the design of the present utility model, the stability of the self-sintering device during lifting can be effectively improved, thereby effectively avoiding accidents.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
