Description

Technical Field

[0001] This utility model relates to the field of material conveying pipe technology, and specifically to a material conveying pipe turning connection structure. Background Technology

[0002] Paste backfilling technology is a green mining technology widely used in the mining industry. It mainly involves processing solid waste such as coal gangue, fly ash, and industrial slag near the coal mine into a toothpaste-like slurry on the ground without dehydration treatment. Then, the paste is transported to the underground backfilling face using a backfilling pump or gravity pressurization through a pump pipeline system.

[0003] The pump pipe system typically starts with a main pipe leading into the mine, then uses pipe clamps to connect bends for rerouting, directing the pump pipe to the required working face. Due to the numerous working faces, workers need to repeatedly disassemble and reassemble the pipe clamps to adjust the bends. After removing the clamps, reinstalling the adjusted bends is challenging because the pump pipes contain a heavy, greasy material, making the connection between two pipes difficult. This requires multiple workers to complete a single adjustment and rerouting operation, resulting in low efficiency and high labor intensity. Utility Model Content
