Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metallurgical furnace technology, specifically a metallurgical furnace intermittent feeding device. Background Technology
[0002] In modern metallurgical production, the charging process of a metallurgical furnace plays a crucial role in smelting efficiency, product quality, and energy consumption control. Traditional intermittent charging devices for metallurgical furnaces primarily achieve quantitative material delivery and batch feeding. However, with the increasing sophistication of metallurgical processes, higher requirements are placed on the particle size uniformity of the materials fed into the furnace. Inconsistent particle size leads to inconsistent reaction rates and uneven heat distribution within the furnace, resulting in prolonged smelting cycles, increased energy consumption, and even affecting the purity and mechanical properties of the metal products. For example, in steelmaking, if the particle size difference of scrap steel or ore is too large, it can cause localized overheating or incomplete reaction within the furnace, reducing the quality of the molten steel.
[0003] Currently, some metallurgical enterprises pre-treat materials by adding independent crushing equipment (such as crushers and grinders) before feeding. However, this method has obvious drawbacks. First, independent crushing equipment occupies a large area, increasing the space cost and equipment investment of the workshop. Second, the material needs to be transferred multiple times, which can easily lead to secondary agglomeration, dust pollution, and material loss. Third, independent crushing equipment and feeding devices cannot achieve coordinated control, making it difficult to dynamically adjust the particle size of the material according to the real-time operating conditions of the metallurgical furnace.
[0004] Therefore, this utility model provides an intermittent feeding device for a metallurgical furnace. Utility Model Content

At the same time, it can also precisely control the rotation speed of the storage port to adjust the frequency of material discharge. The cooperation between the fixed plate and the discharge port can make the material inside the storage port automatically discharged when it moves to a certain extent.

The surface of the fixed support rod 52 is rotatably installed with the crushing roller 53. The drive mechanism 6 includes a support block 61, a drive motor 62, a drive gear 63, a gear ring 64, and a screen 65. The support block 61 is fixedly installed on one side of the housing 1, and the top of the support block 61 is fixedly installed with the support ring 42. The component is fixedly installed with the drive motor 62, the output end of the drive motor 62 is fixedly installed with the drive gear 63, the gear ring 64 is fixedly installed on the top of the rotating ring 51, and the gear ring 64 meshes with the drive gear 63. The screen 65 is fixedly installed on the bottom of the inner wall of the housing 1. The discharge mechanism 7 includes a motor bracket 71, a servo drive motor 72, a fixed plate 73, and a discharge port 74. The motor bracket 71 is fixedly installed on the inner wall of one side of the support leg 2, and the inner wall of the motor bracket 71 is fixedly installed with the servo drive motor 72. The top of one side of the support leg 2 is fixedly installed with the fixed plate 73. A discharge port 74 is provided on the side away from the support leg 2. The material conveying mechanism 8 includes a rotating shaft 81, a connecting plate 82, and a storage port 83. The rotating shaft 81 is rotatably mounted on the top of the fixed plate 73. The bottom of the rotating shaft 81 is fixedly mounted to the output end of the servo drive motor 72. Several sets of connecting plates 82 are provided. The several sets of connecting plates 82 are fixedly mounted in a ring on the surface of the rotating shaft 81.

[0026] like Figures 1 to 5As shown, the fixed bracket 41 and the support ring 42 work together to provide stable support for the feed hopper 43. The feed hopper 43 allows users to easily pour materials into the interior of the housing 1, effectively preventing material spillage and reducing waste. The rotating ring 51, the fixed support rod 52, and the crushing roller 53 work together to rotate and crush the material on top of the screen 65 through the drive mechanism 6, allowing it to flow smoothly into the discharge port 3, thus making the material size more uniform and improving smelting efficiency.

The motor bracket 71 and the servo drive motor 7 The combined use of 2 enables the conveying mechanism 8 to rotate, providing the main power output for its operation. It also allows for precise control of the rotation speed of the storage port 83 to adjust the discharge frequency. The combination of the fixed plate 73 and the discharge port 74 allows the material inside the storage port 83 to be automatically discharged when it moves to a certain extent. The combination of the rotating shaft 81, connecting plate 82, and storage port 83 receives the material discharged from the discharge port 3 and conveys it to the discharge port 74 via the discharge mechanism 7, subsequently discharging it into the furnace. Through continuous conveying and discharging via multiple storage ports 83, an intermittent discharge effect can be achieved. The solenoid valve allows the user to precisely control the discharge state of the discharge port 3, ensuring accurate discharge and preventing spillage while reducing waste.
[0027] Working principle: During operation, first place the housing 1 on a flat surface. Then, the user pours the material into the feed hopper 43. The material then flows through the feed hopper 43 into the inner wall of the rotating ring 51. Materials of appropriate size will fall directly into the discharge port 3 through the screen 65, while larger pieces of material will not fall down. At this point, the user needs to start the drive motor 62 to drive the drive gear 63 to rotate. When the drive gear 63 rotates, it will drive the gear ring 64 to rotate. The rotation of the gear ring 64 will drive the rotating ring 51 to rotate. When the rotating ring 51 rotates, it will drive the fixed support rod 52 to rotate. When the fixed support rod 52 rotates, the crushing roller 53 will contact the screen 65. The material is rolled on the surface of the screen 65. When the crushing roller 53 rolls, it crushes the larger materials on the surface of the screen 65, so that the materials can be discharged smoothly downwards. Finally, the discharge port 3 conveys the crushed materials to the storage port 83. When the storage port 83 is full, the servo drive motor 72 is started to drive the rotating shaft 81 to rotate. When the rotating shaft 81 rotates, it drives multiple sets of connecting plates 82 and the storage port 83 to rotate. As the storage port 83 rotates continuously, the materials inside are also conveyed until they are conveyed to the discharge port 74. Then the materials will fall down along the discharge port 74. As the storage port 83 rotates continuously, it can intermittently feed the furnace.
