【摘要】 双级真空挤出机已经普遍用于砖瓦行业,实现挤出生产自动化、节约资源和提高挤出质量是今后挤出机研究的主要方向。经过对挤出机的结构与实际工作过程的分析研究,确定挤出机整个工作过程的自动化控制方案,应用PLC和传感器,实现了对含水率、料位、真空度、温度和压力的监控,提高了挤出机的自动化程度。同时,也达到了增加产量,延长设备寿命,节约资源,提高生产效率和产品质量的目的。更多还原

【Abstract】 Nowadays,two-stage vacuum extruder has been widely used in brick and tile industry. Main direction in the future of extruder research is to realize extrusion production automation,save resources,improve extrusion quality. Based on analysis of structure and actual work process of extruder,automation control scheme of whole working process of extruder was determined, and PLC and sensor were used to realize monitoring of moisture content,material level,degree of vacuum,temperature and pressure. Degree of automation of extrusion machine was improved. At the same time,the objective which to increase production,extend equipment life,save resources,and improve the production efficiency and product quality was realized.更多还原
