Description

Technical Field

[0001] The utility model belongs to the field of submerged arc furnaces, and particularly relates to a submerged arc furnace electrode column protection system. Background Technique

[0002] A submerged arc furnace is also called an electric arc furnace or a resistance furnace. It is mainly used for reducing and smelting raw materials such as ores, carbonaceous reducing agents, and solvents, and mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, and silicomanganese alloys. It is an important industrial raw material in the metallurgical industry and chemical raw materials such as calcium carbide. At present, the protection screens and protection sleeves in the electrode column protection device are made of stainless steel, and the bottom ring is made of carbon steel. The spare parts of the above three electrode column protection devices are all water-cooled components.

[0003] Chinese Utility Model Patent CN204555706U discloses a submerged arc furnace electrode cooling protection device, which includes a protection sleeve body. Water inlets and outlets are arranged on the end surface of the protection sleeve body. A circulating water channel is arranged inside the protection sleeve body. The circulating water channels are evenly distributed in the protection sleeve body in a wavy shape. The circulating water channels are respectively communicated with the water inlets and outlets. The advantages of the present utility model are that the wavy circulating water channels are evenly distributed in the protection sleeve body, making the structure of the protection device more reasonable and simple, reducing the occurrence of burnout deformation and water leakage. The spacing of the circulating water channels gradually becomes smaller along the direction of water flow, increasing the flow velocity of the circulating water. The wavy protrusions increase the contact area of water, accelerating the heat dissipation speed and improving the cooling effect.

[0004] The above design can accelerate the flow velocity of the circulating water and the heat dissipation effect of the electrode column through the cooperation of multiple groups of components inside the protection sleeve. Although this method is stable, when in use, the overall protection sleeve is in two parts, and the moving distance of the circulating water inside the protection sleeve is too large, which easily causes the temperature of the circulating water to rise during the transportation process, and subsequent heat dissipation cannot be assisted, affecting the overall heat dissipation effect of the equipment and reducing the service quality of the equipment itself. Summary of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the present utility model and briefly introduce some preferred embodiments.

[0026] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the drawings in the specification.

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, as used herein, an "embodiment" or "embodiments" refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0029] As shown by Figure 1 , Figure 2 and Figure 3 shown, a submerged arc furnace electrode column protection system includes a protection assembly 1, a baffle 2, an input port 3, and an output port 4. The protective sleeve is composed of four groups of protection assemblies 1 and is arranged outside the electrode column. A baffle 2 is fixedly installed on the surface of the protection assembly 1. The input port 3 is fixedly installed on one side of the surface of the protection assembly 1, and the output port 4 is fixedly installed on the other side of the surface of the protection assembly 1. A heat dissipation mechanism 5 is fixedly installed inside the protection assembly 1. The heat dissipation mechanism 5 includes a heat dissipation groove 51, a heat dissipation plate 52, and heat dissipation blocks 53. A heat dissipation groove 51 is opened inside the protection assembly 1. The heat dissipation plate 52 is fixedly installed inside the heat dissipation groove 51. The heat dissipation blocks 53 are fixedly installed on the surface of the heat dissipation plate 52 at equal intervals. A splicing mechanism 6 is fixedly installed on one side of the surface of the protection assembly 1, and a transportation mechanism 7 is fixedly installed on the side of the baffle 2.

[0030] During use, through the use of the splicing mechanism 6, the protection assemblies 1 are combined to form a protective sleeve by combining four segments of the protection assemblies 1. Then, the protective sleeve is lifted and transported through the use of the transportation mechanism 7 and installed at the bottom end of the electrode column. After that, through the use of the protection assembly 1 and the heat dissipation mechanism 5, the heat inside the electrode column is guided and removed. Corresponding pipelines are externally connected to the input port 3 and the output port 4. Then, through the use of the input port 3, cooling water is input into the heat dissipation groove 51. Through the use of the heat dissipation plate 52 and the protection assembly 1, the heat dissipated by the electrode column is guided. At this time, the cooling water is transported to the surface of the heat dissipation plate 52 to cool the inner wall of the protection assembly 1 and the outer surface of the heat dissipation plate 52, absorbing the heat inside the protection assembly 1 and the heat dissipation plate 52. Moreover, through the installation of the heat dissipation blocks 53, the contact area between the heat dissipation plate 52 and the cooling water can be expanded, strengthening the heat conduction effect of the component itself, thereby greatly reducing the stability of the electrode column itself and improving the working quality of the equipment itself.

[0031] As shown in the attached Figure 4As shown in the figure, in this embodiment, the input port 3 and the output port 4 are both connected to the heat dissipation groove 51. During use, it is convenient for the cooling water to enter the heat dissipation groove 51 through the input port 3 to guide the heat inside the heat dissipation plate 52 and the protection component 1, and then the water source can be discharged through the output port 4.

[0032] As shown by the attached Figure 4 As shown in the figure, in this embodiment, the heat dissipation block 53 is inclined, and the heat dissipation plate 52 is made of copper material as a whole. During use, by installing the heat dissipation block 53, the contact area between the heat dissipation plate 52 and the cooling water can be enlarged, and the heat conduction effect is more stable. Moreover, when in use, the heat inside the electrode column is guided by taking advantage of the good heat conductivity of the material of the heat dissipation plate 52 itself.

[0033] As shown by the attached Figure 5 As shown in the figure, in this embodiment, the splicing mechanism 6 includes a side plate 61, an insertion block 62, a connection block 63, a slot 64, a moving slot 65, a clamping block 66, a pulling rod 67 and a spring 68. One side of the surface of the protection component 1 is fixedly installed with a side plate 61, and the other side of the surface of the protection component 1 is fixedly installed with a connection block 63. The insertion block 62 is fixedly installed on the side of the side plate 61. A slot 64 is opened inside the connection block 63. A moving slot 65 is opened inside the connection block 63. The moving slot 65 is communicated with the slot 64, and the moving slot 65 is perpendicular to the slot 64. The clamping block 66 is slidably installed inside the moving slot 65. The pulling rod 67 is fixedly installed at the end of the moving slot 65. The pulling rod 67 is slidably connected to the connection block 63. A spring 68 is arranged outside the pulling rod 67.

[0034] During use, multiple groups of protection components 1 are spliced. The insertion block 62 is inserted into the slot 64 inside the connection block 63. During the insertion process of the insertion block 62, the clamping block 66 will automatically contract towards the bottom end of the moving slot 65 due to the extrusion of the insertion block 62. Then the insertion block 62 enters normally. When the insertion block 62 moves to the target position, the internal card slot of the insertion block 62 is exposed. The clamping block 66 loses the extrusion and will automatically pop out under the cooperation of the spring 68 and enter into the card slot to achieve clamping and complete the combination of components.

[0035] As shown by the attached Figure 5 As shown in the figure, in this embodiment, both the insertion block 62 and the clamping block 66 are trapezoidal. During use, by using the shapes of the insertion block 62 and the clamping block 66 themselves, when the insertion block 62 extrudes the clamping block 66, the clamping block 66 will automatically contract into the moving slot 65.

[0036] As shown by the attached Figure 6 As shown in the figure, in this embodiment, the transportation mechanism 7 includes a lifting plate 71, a lifting slot 72 and a plugging slot 73. The lifting plate 71 is fixedly installed on the side of the baffle 2. The lifting slot 72 is opened inside the lifting plate 71. The lifting slots 72 are symmetrically opened on the upper surface of the lifting plate 71.

[0037] During use, through the cooperation of the insertion slot 73 and the lifting slot 72, the hook of the lifting component can be connected to the lifting plate 71, facilitating the subsequent stable movement of the protection component 1. Moreover, the protective sleeves change from the original two groups to four groups, reducing the weight of a single protection component 1 itself, making subsequent movement and replacement more convenient and labor-saving.

[0038] By attachment Figure 1 As shown, in this embodiment, there are four sets of the protection components 1 in total, and the protection components 1 are made of copper material as a whole. During use, by limiting the number of the protection components 1, the composition mode of the traditional protective sleeve can be changed, the water path is shorter, the residence time of the circulating water in the bottom ring is shorter, and the circulating water can always operate at a low water temperature state, with a more significant cooling effect.

[0039] By attachment Figure 1 As shown, in this embodiment, the protection component 1 is made by forging process, reducing the welded parts and weld seams, reducing the risk of welding joint opening under high-temperature working conditions during use, and reducing the number and time of thermal furnace shutdowns caused by bottom ring failures.

[0040] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
