AI Technical Summary

Technical Problem

The existing coal screening devices are prone to accumulation of coal raw materials during the screening process, resulting in a decrease in the effective screening area of ​​the screening plate, reducing the screening efficiency, and difficult to effectively clear, resulting in a decrease in screening quality.

Method used

A coal screening device is designed, including a dispersion mechanism and a dredging mechanism. The dispersion mechanism evenly disperses the coal raw materials to various areas of the screening table through the combination of the rotating block and the dispersion plate to avoid accumulation. The dredging mechanism promptly unblocks the clogged screen holes through the cooperation of the drive motor, screw and cleaning roller to ensure that the coal raw materials are separated according to the particle size.

Benefits of technology

It effectively avoids the accumulation of coal raw materials, increases the effective screening area, improves the screening efficiency and quality, and ensures uniform separation and continuous screening of coal raw materials.
