Description

Technical Field

[0001] The utility model belongs to the technical field of coal gangue screening, and in particular relates to a coal gangue overflow prevention screening device. Background Art

[0002] Coal gangue is solid waste discharged during the coal mining and coal washing processes. It is a black-gray rock that is harder than coal and has a low carbon content and accompanies the coal seam during the coal formation process. The coal gangue raw materials need to be screened during the mining process. At this time, a coal gangue anti-overflow screening device is needed to screen the coal gangue.

[0003] The existing gangue screening devices on the market have the following problems in actual use:

[0004] 1. When the traditional gangue screening device is actually used, the gangue screening device will vibrate. When there is a lot of material in the feed bin, the vibration of the gangue screening device will cause the material in the feed bin to overflow;

[0005] 2. Most gangue screening devices need to screen gangue of different sizes during use. At this time, for gangue of different sizes, it is necessary to select filter screens of appropriate sizes. At this time, it is necessary to replace the filter screen of the gangue screening device. Most gangue screening devices need to remove nut fasteners when replacing the filter screen, which is time-consuming and troublesome to use. Utility Model Content
