Abstract
The adhesion of materials on the return section of blast furnace slag belt conveyors is a serious issue.Therefore,a centralized compressed air cleaning system was designed.The core equipment of this system is a two-stage compression permanent magnet variable frequency screw air compressor with an exhaust capacity of 61.0 m³/min and a rated pressure of 0.8 MPa.After the modi-fication,airflow is distributed to 7 belts through a three-stage pipeline network and stainless steel duckbill nozzles,with outlet pressure stabilized between 0.4-0.6 MPa.Remote automatic control is achieved by PLC.Field operation shows that cleaning efficiency increased from 68.5%to 96%,manual cleaning frequency significantly decreased,providing a reliable cleaning solution for high-moisture bulk material conveying.关键词
