Description

Technical Field

[0001] This utility model relates to the field of carbon raiser screening technology, specifically a carbon raiser screening and impurity removal device. Background Technology

[0002] Carbon raisers are carbon-containing substances added to replenish the carbon content lost during steelmaking. Depending on the raw materials and production processes, carbon raisers can be categorized into wood-based carbon, coal-based carbon, coke-based carbon, graphite-based carbon, etc. Commonly used carbon raisers include carbonized pig iron, electrode powder, petroleum coke powder, charcoal powder, and coke powder.

[0003] The production process of carbon raisers requires the raw materials to be crushed and screened to facilitate subsequent mixing and drying. It should be noted that the finer the raw materials are crushed during carbon raiser production, the faster the reaction rate, but at the same time, it is easy to generate dust pollution, which is not conducive to subsequent screening. Therefore, how to deal with dust pollution during the screening process and achieve effective dust removal is an urgent problem to be solved.

[0004] The authorized announcement number discloses a sieving device for removing impurities in the production and processing of carbon raisers, belonging to the field of sieving devices. It includes a frame, with a surrounding plate fixedly connected to the top edge of the frame, and a top plate fixedly connected to the top of the surrounding plate. An exhaust pipe is fixedly connected to the top surface of the top plate and is connected to an external exhaust device. A screening screen cylinder is rotatably connected inside the surrounding plate, and a material-blocking and knocking component is provided inside the screening screen cylinder. A first discharge bin and a second discharge bin are fixedly connected to the frame below the screening screen cylinder, and a dust removal mechanism is provided inside the first discharge bin.

[0005] This device screens and grinds particles of different sizes together, which means that even particles of the right size still need to be ground. This design results in an excessive workload and reduced work efficiency. To address this, we propose a carbonizer screening and impurity removal device. Utility Model Content
