摘要
抽屉窑在电瓷生产中占据重要地位,其气氛控制精度直接影响产品质量与能耗。传统多电磁阀脉冲控制方式存在气氛波动大、能耗高、自动化程度低等弊端。文中提出一种基于比例阀结合线性控制阀调节的脉冲燃烧气氛控制技术,旨在实现抽屉窑还原阶段温度和气氛的自动化精准控制。通过介绍该气氛控制系统的构成与工作原理,阐明其借助比例阀连续调节流量、线性控制阀精准改变气氛制度,并结合脉冲燃烧技术,达成温度和气氛的独立控制。实验结果表明,相较于传统多电磁阀控制方式,该技术在氧化和还原阶段均能显著提升气氛控制的精确性和稳定性,降低能耗约8%,且实现全自动化控制,提高产品质量一致性和生产效率。综合对比分析显示,比例阀结合线性控制阀调节的气氛控制方式在多方面具备显著优势,为电瓷抽屉窑升级改造提供有效方案,应用前景广阔。
Drawer kilns play an important role in electrical porcelain production,and the precision of atmosphere control directly affects product quality and energy consumption.Traditional multi-solenoid valve pulse control methods suffer from significant atmosphere fluctuations,high energy consumption,and low automation levels.The author proposes a pulse combustion atmosphere control technology based on proportional valves combined with linear control valves,aiming to achieve automated and precise control of temperature and atmosphere during the reduction stage of the kiln.By introducing the structure and working principle of this atmosphere control system,it is explained that how it utilizes proportional valves for continuous flow regulation and linear control valves for precise atmosphere adjustment,integrating pulse combustion technology to achieve independent control of temperature and atmosphere.Experimental results show that,compared to traditional multi-solenoid valve control,this technology significantly improves the accuracy and stability of atmosphere control in both oxidation and reduction stages,reduces energy consumption by approximately 8%,and enables fully automated operation,enhancing product consistency and production efficiency.A comprehensive comparative analysis confirms that the proportional valve and linear control valve-based atmosphere control method offers significant advantages in multiple aspects,providing an effective solution for the upgrading and retrofitting of electrical porcelain drawer kilns with broad application prospects.
