Description
Technical Field
[0001] The utility model belongs to the technical field of slurry filling equipment, and in particular relates to a slurry filling pipeline with an automatic pipe blockage monitoring and dredging device. Background Art
[0002] Slurry filling technology is a green mining technology that crushes and grinds solid waste such as gangue generated during coal production and utilization, adds water to make a slurry of a specific concentration, and transports it to coal mine goafs or other residual spaces through slurry pipelines. It has significant advantages such as high filling adaptability, large solid waste treatment capacity, and low overall cost. However, during the transportation process, due to unreasonable slurry concentration design, insufficient pumping pressure, improper pipeline layout, and irregular personnel operation, the slurry material dehydrates, settles, stratifies, and segregates in the pipeline, resulting in pipeline blockage.
