This can effectively prevent impurities from circulating in the coal pipelines. However, most of the filtering devices are not very convenient to disassemble.

[0003] For example, the utility model with patent number CN201320011107.7 discloses an online filtering device for a coal transportation pipeline, which can intercept and filter the debris carried in the coal slurry in the pipeline online, and completely eliminate the safety hazards and economic losses caused by the debris. The online filtering device is composed of a positive Y-shaped pipeline, a reverse Y-shaped pipeline, a pressure gauge, a filter unit No. 1, a filter unit No. 2, a valve, and a flange. The filter unit No. 1 and the filter unit No. 2 have the same structure, and are both composed of a filter tube, two layers of filter screens, two valves, and three groups of flanges connected in a certain order. A pressure gauge is installed on each of the unbranched sections of the positive Y-shaped pipeline and the reverse Y-shaped pipeline. When the pressure difference between the two pressure gauges suddenly increases, it indicates that there is debris in the filter tube. The two filter units are backup for each other to ensure the normal and continuous operation of the coal transportation pipeline when clearing the debris in the filter tube;
