摘要: 为解决冬季精煤运输过程发生冻结、精煤粘结在车厢内壁上造成卸煤困难的问题,需在装车前将防冻液均匀喷洒在列车厢体内壁及底部,并在精煤进入缓冲仓之际将防冻液喷洒在煤流中,为节约防冻液,要求在两节车厢的间隔处停止喷洒。通过对某矿防冻液系统装置进行升级改造,实现车厢喷洒与缓冲仓煤流喷洒的自动控制,解决了两车厢之间因不停止喷洒而对环境造成污染的问题,节省了人力和大量防冻液,设计和元件选型中,充分考虑了使用环境寒冷、风向等恶劣条件,使系统可靠工作。

Abstract: In order to solve the problem of freezing of fine coal transportation in winter and the difficulty of coal unloading caused by the bond of fine coal on the inner wall of the carriage,it is necessary to evenly spray antifreeze on the inner wall and bottom of the carriage body before loading the carriage.And when the fine coal enters the buffer warehouse,the antifreeze is sprayed into the coal flow.In order to save the antifreeze,it is required to stop spraying at the interval between the two cars.By upgrading the anti-freeze liquid system,automatic control is realized between the car spraying and the coal flow spraying in the buffer tank,which solves the problem of environmental pollution caused by the non-stop spraying between the two cars,and saves manpower and a large amount of anti-freeze liquid.In the design and component selection,the bad conditions such as cold environment and wind direction are fully considered,so that the system can work reliably.
