Description

Technical Field

[0002] The coal separation device for blast furnace ironmaking is a device specially designed for efficiently separating coal from mixed raw materials. It mainly uses physical methods such as vibrating screens, magnetic separation, gravity separation and other technologies to effectively separate coal from impurities such as rocks and soil, meeting the demand for high-quality coal in the blast furnace ironmaking process and improving production efficiency and product quality.

[0003] The Chinese patent with announcement number CN221157571U discloses a coal screener with a vibrating separation mechanism. By starting the motor, the output end of the motor drives the second bevel gear to rotate, and the first bevel gear follows the rotation, so that the first connecting rod rotates with the U-shaped rod. When the U-shaped rod rotates to the left, the second connecting rod drives the square seat to move to the left. When the U-shaped rod rotates to the right, the second connecting rod pushes the square seat to move to the right. The U-shaped rod keeps rotating, so that the second connecting rod drives the screening plate to vibrate back and forth, quickly removing impurities and large pieces of matter in the coal, greatly improving the efficiency of coal screening compared with traditional devices; however, the above-mentioned device is inconvenient to remove the screened material when in use, and the screening plate needs to be frequently removed, which greatly affects the continuity and efficiency of the production process.

At the same time, the accumulated material is prone to friction with the screening plate, increasing the risk of equipment failure and increasing the safety hazards of the operator.
