Description

Technical Field

[0001] This utility model relates to the field of deoxidizer feeding technology for refining furnaces, specifically a device for uniform diffusion feeding of deoxidizer in refining furnaces. Background Technology

[0002] Refining furnaces are key equipment in the metallurgical industry used for deep processing of molten metal. They are mainly used to improve the purity of molten steel or non-ferrous metals, adjust the chemical composition, and optimize material properties. Refining furnace deoxidizers are additives used to remove oxygen from molten metals. Their main function is to reduce the oxygen content in molten steel and improve the purity of the steel.

[0003] Currently, deoxidizers for refining furnaces are added inside the furnace body through the feed inlet. However, the feed inlet is fixed and singular, resulting in a small concentrated feeding space for deoxidizers entering the furnace body through a single fixed feed inlet. Consequently, the deoxidizers are unevenly distributed in the feeding space within the furnace body, and the concentrated feeding of deoxidizers leads to a slow mixing speed within the furnace body.

[0018] like Figures 1 to 3 As shown, the deoxidizer uniform diffusion feeding device for the refining furnace in this embodiment includes a storage hopper 1 and a refining furnace body 2. The top of the refining furnace body 2 is provided with a top cover plate 3, and the bottom of the refining furnace body 2 is provided with a discharge port. A discharge valve is provided on the discharge port. A discharge outlet is provided on the top of the top cover plate 3. A feeding mechanism 5 is provided at the upper end of the inner side of the refining furnace body 2. A stirring mechanism is provided inside the refining furnace body 2. The bottom of the feeding mechanism 5 is connected to the stirring mechanism. A rotating mechanism 4 is provided on the top of the top cover plate 3. Connected to the feeding mechanism 5, the top of the top cover plate 3 is provided with a storage hopper 1 via a bracket 9. The top of the storage hopper 1 is provided with a material inlet, and the bottom of the storage hopper 1 is provided with a feeding pipe 8. The feeding pipe 8 is provided with a feeding valve, and the bottom of the feeding pipe 8 is connected to the rotating mechanism 4 via a rotary joint 7. The deoxidizer is fed in a large space with a multi-position rotary dispersion in the refining furnace body 2. The feeding is uniformly diffused. The rotary dispersion feeding has the function of feeding agitation and diffusion, so that the deoxidizer can be more quickly and uniformly diffused and mixed in the refining furnace body 2.

[0019] Specifically, the feeding mechanism 5 includes a hollow feeding rod 51, a first feeding hopper 52, a second feeding hopper 53, a first feeding port 54, and a second feeding port 55. The bottom of the rotating mechanism 4 is provided with the hollow feeding rod 51, which is located inside the refining furnace body 2. The lower end of one side of the hollow feeding rod 51 is connected to the first feeding hopper 52, and the lower end of the other side of the hollow feeding rod 51 is connected to the second feeding hopper 53. The bottom of the first feeding hopper 52 is located away from the end of the hollow feeding rod 51. The unit is equipped with a No. 1 feed inlet 54, and a No. 2 feed hopper 53 has a No. 2 feed inlet 55 at the bottom of the end away from the hollow feed rod 51. The deoxidizer falls through the hollow feed rod 51 and is guided by the concentrating plate 57 to fall in a concentrated manner. The concentrated falling deoxidizer is dispersed into the No. 1 feed hopper 52 and the No. 2 feed hopper 53 through the dispersing plate 56. The deoxidizer is dispersed into the refining furnace body 2 through the No. 1 feed inlet 54 at the bottom of the No. 1 feed hopper 52 and the No. 2 feed inlet 55 at the bottom of the No. 2 feed hopper 53.

[0020] Furthermore, the rotating mechanism 4 includes a first gear 41, a second gear 42, and a servo motor 43. The top of the top cover plate 3 is provided with the meshing first gear 41 and second gear 42. The top of the first gear 41 is connected to the feed pipe 8 via a rotary joint 7, and the bottom of the first gear 41 is connected to the hollow feed rod 51. The middle of the first gear 41 has a feed hole communicating with the rotary joint 7 and the hollow feed rod 51. The top of the top cover plate 3 is equipped with a servo motor 43 via a motor bracket. The output end is connected to the gear shaft at the top of the second gear 42 via a coupling. The servo motor 43 drives the second gear 42 to rotate, which in turn drives the first gear 41 meshing with it to rotate, causing the hollow feed rod 51 and the stirring rod 6 to rotate inside the refining furnace body 2. The deoxidizer in the storage hopper 1 enters the hollow feed rod 51 through the feed pipe 8, the rotary joint 7 and the feed hole on the first gear 41. During the feeding process, the first feed hopper 52 and the second feed hopper 53 continuously rotate and disperse the feed inside the refining furnace body 2.

[0021] Furthermore, the stirring mechanism includes a stirring rod 6 and stirring blades 61. The bottom of the hollow feed rod 51 is provided with a stirring rod 6, and a number of stirring blades 61 are provided on the stirring rod 6. During the rotating and dispersing feeding process, the stirring rod 6 drives the stirring blades 61 to rotate in the refining furnace body 2, stirring and mixing the deoxidizer entering the refining furnace body 2.

[0022] Furthermore, the ends of the No. 1 feed hopper 52 and the No. 2 feed hopper 53 that are away from the hollow feed rod 51 are both inclined downwards. The length of the No. 1 feed hopper 52 is greater than the length of the No. 2 feed hopper 53. That is, the No. 1 feed port 54 on the No. 1 feed hopper 52 and the No. 2 feed port 55 on the No. 2 feed hopper 53 are located in different positions in the feeding space inside the refining furnace body 2.

[0023] Furthermore, a dispersing plate 56 is provided inside the hollow feed rod 51 between the first feed hopper 52 and the second feed hopper 53. The dispersing plate 56 is arranged in an arc-shaped protrusion structure. The upper protruding arc-shaped dispersing plate 56 can disperse and guide the deoxidizer in the hollow feed rod 51. One side of the dispersing plate 56 is connected to the first feed hopper 52, and the other side of the dispersing plate 56 is connected to the second feed hopper 53. The feeding and dispersion between the dispersing plate 56 and the first feed hopper 52 and the second feed hopper 53 is smooth and unobstructed.

[0024] Furthermore, the hollow feed rod 51 above the No. 1 feed hopper 52 and the No. 2 feed hopper 53 is equipped with a concentrating plate 57. The concentrating plate 57 is a V-shaped structure with an open bottom. As the deoxidizer falls inside the hollow feed rod 51, it is guided and concentrated by the concentrating plate 57 and falls onto the dispersing plate 56. The concentrated falling deoxidizer is dispersed into the No. 1 feed hopper 52 and the No. 2 feed hopper 53 through the dispersing plate 56. The feed is evenly dispersed in the No. 1 feed hopper 52 and the No. 2 feed hopper 53 and then discharged.

[0025] The usage method of this embodiment is as follows: The deoxidizer is stored inside the storage hopper 1. When deoxidizer needs to be added inside the refining furnace body 2, the feed valve on the feed pipe 8 is opened, and the servo motor 43 is started. The servo motor 43 drives the second gear 42 to rotate, which in turn drives the first gear 41 meshing with it to rotate, causing the hollow feed rod 51 and the stirring rod 6 to rotate inside the refining furnace body 2. The deoxidizer in the storage hopper 1 enters the hollow feed rod 51 through the feed pipe 8, the rotary joint 7, and the feed hole on the first gear 41. As the deoxidizer falls inside the hollow feed rod 51, it is guided and concentrated by the concentrating plate 57. The concentrated deoxidizer is dispersed into the first feed hopper 52 and the second feed hopper 53 by the dispersing plate 56. The deoxidizer is then fed from the first feed hopper 52. The No. 1 feed inlet 54 and the No. 2 feed hopper 53 at the bottom disperse into the refining furnace body 2. During the feeding process, the No. 1 feed hopper 52 and the No. 2 feed hopper 53 rotate continuously inside the refining furnace body 2, causing the No. 1 feed inlet 54 and the No. 2 feed hopper 55 at different positions inside the refining furnace body 2 to continuously rotate and disperse the feed. The deoxidizer is fed into the refining furnace body 2 in a large space with multiple rotating positions, and the feed is evenly diffused. During the rotating and dispersing feeding process, the stirring rod 6 drives the stirring blade 61 to rotate inside the refining furnace body 2, stirring and mixing the deoxidizer entering the refining furnace body 2. The rotating and dispersing feeding has the function of stirring and dispersing the feed, so that the deoxidizer can be more quickly and evenly diffused and mixed inside the refining furnace body 2. The feed valve is closed when the feeding is finished.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
