Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting technology, and in particular to a sintering and ironmaking integrated ore blending device. Background Technology

[0002] Against the backdrop of increasingly scarce high-quality ironmaking resources and the low-carbon development of the steel industry, optimizing ore blending technology is a key technology for the rational allocation of internal and external market resources of steel enterprises. By optimizing ore blending technology, the cost and carbon emissions of blast furnace ironmaking processes can be reduced, and the research and innovation of optimized ore blending technology can be promoted, which is a powerful measure to help steel enterprises reduce costs and increase efficiency.

[0003] Sintering is a crucial step in iron and steel smelting. Before blast furnace smelting, powdered iron ore raw materials are mixed and sintered to form sintered ore, which then enters the smelting process. The quality of the sintered ore directly affects the quality of ironmaking. Nowadays, the widespread use of mineral powders, ores, and various iron-containing industrial materials in the production process has made the types and compositions of sintering raw materials increasingly complex and diverse. However, the operation of the batching scales still relies heavily on manual labor, leading to uneven mixing. This directly and negatively impacts the quality of the sintered ore, making it difficult for the performance and stability of the sintered ore to meet the expected standards and the user's demand for high-quality sintered ore. It also reduces the actual application effect and overall practicality of the equipment, causing many inconveniences in production and operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sintering and ironmaking integrated ore blending device, which aims to improve the problems of complicated steps and inaccurate quantity control in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sintering and ironmaking linkage ore blending device, comprising a base, a second motor fixedly connected to the top of the base, a rotating column fixedly connected to the output end of the second motor, a spiral lifting disc fixedly connected to the outer wall of the rotating column, a housing provided on the top of the second motor, a screening arc plate fixedly connected to the bottom of the housing, a feed inlet connected to the top of the housing, a receiving box fixedly connected to the front side of the base, a mixing tank provided on the front side of the housing, and a metering mechanism provided on the top front side of the mixing tank, the metering mechanism being used to quantitatively control the added solvent.

[0006] As a further description of the above technical solution: the metering mechanism includes a motor, the bottom of which is fixedly connected to the top front side of the base. A rotating chuck is fixedly connected to the output end of the motor. A four-opening disc is engaged with the outer wall of the rotating chuck. A rotating shaft is fixedly connected to the middle of the four-opening disc. A metering disc is fixedly connected to the top of the outer wall of the rotating shaft. Circular openings are provided on the left and right sides of the top of the metering disc. A liquid storage bottle is provided on the top of the metering disc.

[0007] As a further description of the above technical solution: a hollow fixing column is fixedly connected to the bottom of the liquid storage bottle, and the bottom of the hollow fixing column is fixedly connected to the top of the mixing tank.

[0008] As a further description of the above technical solution: a small round hole is provided in the middle of the metering disc, and the bottom of the rotating shaft is rotatably connected to the top of the mixing tank.

[0009] As a further description of the above technical solution: a second feed inlet is fixedly connected to the top rear side of the mixing tank, and the top of the second feed inlet is located at the bottom of the screening arc plate.

[0010] As a further description of the above technical solution: the bottom of the base is provided with foot supports, and the right side of the outer wall of the base is connected to a conveying pipe.

[0011] As a further description of the above technical solution: a blast furnace is connected to the right side of the conveying pipeline.

[0012] As a further description of the above technical solution: the top of the blast furnace is fixedly connected to a flue gas outlet, and the bottom of the blast furnace is provided with a support frame.

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

[0014] In the scheme of this application:

[0015] 1. The spiral lifting disc is driven by the rotating column of the motor, which can transport the ore raw material added at the feed port one upward. During the transport process, the ore is processed by the screening arc plate, which can effectively separate sand, gravel, impurities and ore that is too small in size. The separated material falls into the bottom receiving box for secondary screening. This structure can remove impurities and unqualified raw materials that will affect subsequent processes in advance, and avoid them interfering with the ore mixing effect, thereby ensuring the final quality of sintered ore and improving production stability.

[0016] 2. Solvent is pre-filled into the storage bottle. The motor drives the rotating chuck to rotate. For every revolution of the chuck, the four-opening disc rotates a quarter revolution. The rotating shaft drives the metering disc to move intermittently, so that the two circular openings at the top of the metering disc regularly discharge the solvent. This allows for precise control of the amount of solvent entering, eliminating the need for manual measurement at each scale. This simplifies the operation process, reduces the difficulty of manual operation, and provides users with a convenient and efficient way to add solvent. Attached Figure Description

[0038] The operation process of the sintering and ironmaking integrated ore blending device provided by this utility model is as follows:

[0039] By adding ore raw materials into the feed inlet 8, after entering the interior of the outer shell 6, the rotating column 4 at the output end of the motor 3 drives the spiral lifting disc 5 to rotate, conveying the ore raw materials upward. After passing through the screening arc plate 7, the sand and impurities in the ore raw materials will be screened out, and the ore that is too small will also be screened out. The receiving box 9 at the bottom is used to collect impurities and small raw materials, which is convenient for secondary screening. This structure can avoid affecting the subsequent mixing effect, thereby affecting the quality of the sinter.

[0040] When solvent needs to be added, it is placed in the storage bottle 207 in advance. By controlling the motor 201, the rotating chuck 202 at the output end is rotated. For every rotation of the rotating chuck 202, the four-opening plate 203 rotates a quarter turn. Through the rotating shaft 204, the metering plate 205 at the top is driven to move intermittently, so that the two circular openings 206 at the top of the metering plate 205 can regularly discharge the material, control the amount entering, and make it convenient for users to operate, saving the step of slowly measuring the scale.
