| 中文摘要: |
| 回转窑的运行环境十分恶劣，长时间高负荷的连续运转以及环境中的飞砂会导致窑中心线会发生偏移，从而引发许多问题。本文在国内同行的设计思路上，将部分装置进行了改进，将与轮带接触的T型卡尺改成了滚轮装置。通过压力传感器将滚轮受到的力以数字信号方式输出，同时结合了传统的三点法，运用微分和最小二乘法等数学工具拟合所测量的轮带，通过数据计算，得到回转窑的垂直中心线偏差结果。 |
| 英文摘要: |
| The operating environment of rotary kiln is very bad. The continuous operation with high load for a long time and the flying sand in the environment will lead to the deviation of the kiln centerline, which will cause many problems. In this paper, based on the design ideas of domestic peers, some devices have been improved, and the T-type caliper contacted with the tire has been changed into a roller device. The force exerted on the roller is output in the form of digital signal through the pressure sensor. At the same time, the traditional three-point method is combined, and mathematical tools such as differential and least square method are used to fit the measured tire. Through data calculation, the vertical centerline deviation of the rotary kiln is obtained. |
