粉状乳化炸药在生产线输送中的摩擦升温研究
Friction Induced Temperature Increase of Powdered Emulsion Explosives during Production Line Transportation
摘要
Abstract
In order to ensure the safety of powdered emulsion explosives in production line transportation,the tem-perature changes caused by friction between powdered emulsion explosives and transportation equipments were studied.In the production lines of powdered emulsion explosives at temperatures of 15,25℃,and 30℃,the temperature of the air delivery system equipment and the hot material screw were tested,and the temperature rise phenomenon caused by the fric-tion between powdered emulsion explosives and equipments under different operating times and temperatures was analyzed.A small-scale screw conveyor was constructed to test the temperature changes of the pipe wall at different screw speeds.The results indicate that as the operating time increases,the surface temperature of the air conveying system equipment shows a trend of first increasing and then decreasing.As the temperature increases,the maximum temperature,maximum tempera-ture rise,and heating rate of the equipment surface all increase.Meanwhile,the temperature of the explosive at the hot ma-terial screw conveyor also exhibits a similar variation pattern.The wall temperature of the small-scale screw conveyor in-creases first and then stabilizes with the increase of the screw speed.By studying the temperature changes caused by friction between powdered emulsion explosives and the equipment during transportation,it is possible to more accurately ensure that the production and transportation of powdered emulsion explosives are within a safe temperature range and reduce the risk of accidents.关键词
