摘要
Abstract
The key technical points of vertical air cushion belt conveyor are the pressing force and the bearing capacity of gas film in concave-convex arc section.Whether the gas film bearing capacity provided by the concave-convex arc air chamber can meet the transportation requirements is the key to decide whether the air chamber can replace the idler.Through the stress analysis of the convex arc section,the formulas of conveyor belt tension and gas film bearing capacity were derived,and the number of air holes was changed.The double-arc air chambers with 5 rows,7 rows and 9 exhaust holes in the positive pressure area were selected for simulation,and the total pressure cloud map and positive lateral pressure bearing capacity were compared.The results show that the flow loss in the double-arc gas chamber with 5 exhaust holes was reduced,the gas film was stable and the bearing capacity was high.关键词
