Technical Problem
其中，风墙式镜头保护的方式是通过整体均匀的流场带走烟尘，但该方式对设备的风量需求高，会增加过滤系统负荷，同时均匀性控制复杂，风墙出口风速难以横跨整个成形室宽度，保护效果存在一定缺陷，且风墙的干净气体进入成形室后即被污染，保护效果有限
Benefits of technology
[0019]本实用新型提供了一种成形室内部保护气氛形成装置，该装置包括吹风口、吸风装置以及上吹风导流装置；吹风口与上吹风导流装置相贯通并通过上吹风导流装置吹出从保护镜扫过且并行于成形室顶板的上吹风保护气流；吸风装置吸引上吹风保护气流。本实用新型利用过滤后的惰性气体进行镜头保护，可以避免引入新鲜的惰性气体，有效降低气体消耗，降低使用成本。延伸的主要作用是避免过滤后的循环气体被污染，因为成形室内充斥着粉末和黑烟杂质，吹风口的气体一旦流出风口进入成形室就会被污染，因此延伸上吹风口，使上吹风干净气流到达保护镜之前，不和成形室内受污染的气体掺混，可有效提升保护效果，提升设备的可靠性。
