垃圾破碎机控制系统设计

Design of waste crusher control system

摘要:

基于大流量（生活垃圾可达40t/h）的垃圾破碎机，能满足在常规流量和试验阶段的大流量破碎需求。破碎机设计功率250kW，设计扭矩2x66000N·m，最大工作压力35MPa。其控制系统采用西门子PLC1500作为控制中心，配备就地显示屏、ABB变频器，通过Profinet总线通信连接在一起，经由显示屏通过Profinet总线实现破碎机的所有操作。控制系统通过采集一次仪表运行数值实现破碎机的报警、连锁，保证其正常可靠运行。采用模块化编程，优化核心算法，使破碎机的在不同工况下运行更加稳定可靠。根据上游来料量的不同，调节变频器，使垃圾破碎机运行在不同的速度，达到环保节能的目的。

Abstract:

The waste crusher based on large flow rate (up to 40t/h of household waste) can meet the crushing demand of large flow rate in normal flow rate and test stage. The designed power of the crusher is 250kW, the designed torque 2x66000N·m, and the maximum working pressure is 35MPa. Its control system uses Siemens PLC1500 as the control center, equipped with local display screen, ABB converter, and connected by Profinet bus communication. The control system realizes the alarm and interlock of the crusher by collecting the operation value of the primary instrument, ensuring its normal and reliable operation. Using modular programming and optimizing the core algorithm, the crusher runs more stably and reliably under different working conditions. According to the different amount of upstream incoming material, the frequency converter is adjusted to make the waste crusher run at different speeds, so as to achieve the goal of environmental protection and energy saving.
