大型密闭式电石炉原料自动输送系统设计与应用

Design and Application of Automatic Conveying System for Raw Materials in Large Closed Calcium Carbide Furnace

以64万吨/年电石项目为背景,分析了40000kVA大型密闭式电石炉原料输送的工艺特点,设计了电石炉原料自动输送控制方案。为保证输送精度,在卸料小车上采用了编码器技术,实现了对卸料小车位置和速度的精确测量和控制。通过系统的实际应用验证,实现了原料输送和过程管理的全局自动化生产,在全自动化控制与运行方面达到了应用要求,同时系统的抗干扰能力、环境适应性等都达到了预定目标。

Based on the background of 640000 tons/year calcium carbide project belong to Xinjiang Tianchen chemical CO., LTD, The paper analyses the process features of raw material conveying in 40000kVA large closed calcium carbide furnace, and presents the design of the automatic control program of this process. To ensure tranmit precision of the dump car, introduces encoding technology and finally have realized accurate measuerment and control of position and velocity. After the application of the system, atuomatic conveying of raw materials and global automation production of process management come true. The system have meet the requirement of global automatic control and operation, meanwhile the anti-interference ability and environment adaptability of the system have achieved the goal.
