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。
Two-stage vacuum extruder has been widely used in brick and tile industry, the realization of extrusion production automation, resource conservation and improve the quality of extrusion is the future of the main direction of the extruder. After the structure of the extruder and the actual work process analysis and research to determine the entire extruder extruder automation control program, the application of PLC and sensors to achieve moisture content, level, vacuum, temperature and pressure monitoring, Improve the degree of automation of the extruder. At the same time, it also achieved the goal of increasing output, extending equipment life, saving resources, improving production efficiency and product quality.
