Description

Technical Field

[0001] The utility model belongs to the field of blue carbon screening, and in particular relates to a blue carbon screening device. Background Art

[0002] The semi-coke screening device is a device used to screen and separate semi-coke in the coal industry. After screening, it can be classified and graded according to different particle sizes and quality requirements to meet different industrial production and market needs.

[0003] Most of the existing lignite screening devices screen the lignite by driving a shaftless drum screen through a supporting wheel or a gear drive. However, during use, the driving method through the supporting wheel is highly dependent on the friction between the supporting wheel and the screening drum. Over time, the supporting wheel is prone to wear, which can cause slipping, and the screening drum cannot rotate normally, which greatly affects the screening effect, and its daily maintenance is also very cumbersome.

[0004] Therefore, in order to address the problems that the above-mentioned lignite screening device suffers from large wear between the supporting wheel and the screening drum during use, and the screening drum has poor stability during rotation, a lignite screening device is developed. By adding an annular auxiliary structure, a quick maintenance structure and an anti-splash structure to the lignite screening device, the stability of the device during use can be greatly improved, the service life of its supporting wheel can be increased, and the maintenance cost of the device can be greatly reduced.
