摘要
跳汰选煤的自动化程度决定了原煤洗选的效率和产品的质量,针对选煤厂跳汰机自动化程度低的现状,研制了灰分回控跳汰机控制系统,实现了给煤量、排料量、数控风阀的自动控制。将模糊PID控制算法应用于系统的自动排料过程,取得了明显效果。煤炭灰分的在线回控保证了成品煤的灰分指标。
The automation degree of Jigger decides the washing efficiency and the product quality of the raw coal. Aiming at the situation that the automation degree of jigger is low, ash feedback and jigger control system was developed. It realizes the auto-control giving coal amounts ,discharge material amounts, air-valve autocontrol. It obtains good effect that the fuzzy PID control applied in the process of auto-discharging. The ash online feedback ensurs the ash target of clean coal.
