采用多象限噪声法监视磨煤机煤位的装置
摘要：
本发明的目的是提供一种煤位监视精度高的采用多象限噪声法监视磨煤机煤位的装置，包括磨煤机、安装在磨煤机钢筒外侧的4N*(1≤N≤4)个压电陶瓷拾音器以及外置式处理器，以磨煤机钢筒的轴心为中心，将磨煤机钢筒的外周侧壁四等分成四个象限区，每个象限区内均匀贴合有N*(1≤N≤4)个压电陶瓷拾音器，每个压电陶瓷拾音器上安装有倾角仪，所述外置式处理器电连接每个压电陶瓷拾音器以读取、记录信号压电陶瓷拾音器输出的电信号以判断磨煤机的煤位。
摘要（英）：

The invention aims at providing a device for monitoring coal position of a coal mill through a multiquadrant noise method. The device comprises the coal mill, 4N*(N ranges from 1 to 4) piezoelectric ceramic pick-ups mounted at the outside of a steel barrel of the coal mill, and an external processor, wherein the peripheral sidewall of the steel barrel of the coal mill is quartered into four quadrant areas by treating an axis of the steel barrel of the coal mill as the center; N*(N ranges from 1 to 4) piezoelectric ceramic pick-ups are uniformly adhered in each quadrant area; an inclinometer is mounted on each piezoelectric ceramic pick-up; the external processor is connected with each piezoelectric ceramic pick-up and used for reading and recording an electric signal output by each piezoelectric ceramic pick-up in order to determine the coal position of the coal mill.
