浮法在线生产低辐射镀膜玻璃的成套装置 技术领域
本发明涉及一种镀膜玻璃生产设备, 尤其是一种浮法在线生产低辐射 镀膜玻璃的成套装置。 背景技术
低辐射镀膜玻璃亦称 "Low- E"玻璃, 由于它能有效地阻断室内外的辐 射传热,具有很好的保温节能效果,因此它在建筑上得到越来越广泛的应用。 为了制造优质的低辐射镀膜玻璃, 浮法玻璃在线镀膜需要一套合适的镀膜器 和适宜的镀膜环境,要求在线镀膜器结构参数稳定、镀膜反应区的数量可调, 实现膜层厚度范围的可调, 要求设备操作灵活方便、 拆装快捷; 同时, 镀膜 环境必须具备均匀的温度场、 压力场及流速场。
但是, 现有的浮法玻璃在线镀膜设备, 有的是功能单一, 只能镀膜层 较薄的阳光控制膜玻璃; 有的是不能实现对膜层厚度大范围的调节, 不能 适应大流量的反应气体镀膜的要求, 因而产品的功能和质量受到限制。 另 外, 现有浮法玻璃生产线很少为浮法玻璃在线镀膜装置配备达到镀膜工艺 要求的镀膜环境装备, 因此在浮法玻璃生产线退火窑 AO区普遍存在着气流 紊乱, 窑压不稳、 温度场难以控制, 设备操作难度大等问题, 使浮法玻璃 在线镀膜质量受到很大的影响, 极大的增加浮法在线镀膜技术在浮法玻璃 生产线实施的工艺控制难度。 公开日为 2007 年 1 月 24 日、 公开号为 CN1899998的专利文件公开了一种在平板玻璃上进行镀膜的方法和设备,适 用于在浮法玻璃生产线锡槽出口处,在线生产液态或固态镀膜玻璃,特别适 用于阳光控制镀膜,而且是膜层中含有金属氧化物的镀膜。该发明在锡槽出 口处的镀膜区域添加一独立的气氛控制室,使镀膜机、排气装置位于气氛控 制室内,该气氛控制室是单独的、 不与锡槽相连通的,在气氛控制室内充满 有氧化气体氛围,并保持氧化气体的压力一定。 由于该发明没有气流调节装 置, 温度场也不易稳定, 另外, 该发明需要给气氛控制室不断充气, 成本 高, 而且外部充气对镀膜工艺气流容易造成冲击, 影响镀膜质量。
发明的公开
本发明为解决目前现有镀膜设备存在的镀膜功能单一、 膜层调节范围 小及镀膜质量差的问题而提供一种镀膜功能全、 膜层厚度调节范围大、 鍍 膜质量好的浮法在线生产低辐射镀膜玻璃的成套装置。
本发明为达到上述技术目的所采用的具体技术方案为: 一种浮法在线 生产低辐射镀膜玻璃的成套装置, 包括前端口与浮法玻璃生产线的过渡辊 台区相连、 后端口与浮法玻璃生产线退火窑 A1区相连的退火窑 AO区在线 镀膜环境成套调节装置以及设置在镀膜环境成套调节装置内的镀膜器, 所 述的退火窑 AO区在线镀膜环境成套调节装置包括壳体, 壳体内安装有承载 玻璃带从过渡辊台区向退火窑 A1区运行的传送辊, 在壳体与过渡辊台区连 接处的传送辊上方设有第一挡帘和第一上翻板, 传送辊下方设有第一下翻 板, 壳体与退火窑 A1区连接处的传送辊上方设有第二挡帘和第二上翻板, 传送辊下方设有第二下翻板, 壳体内设有加热器, 壳体的侧壁上设有观察 窗, 壳体上设有与壳体内腔相通的温度监测装置和压力调节装置, 壳体的 顶部设有放置镀膜器的开口, 所述的镀膜器包括多块相互平行的底板, 相 邻的两块底板之间设有狭缝, 狭缝的长度与玻璃带的宽度相适配, 狭缝分 别与设置在狭缝上方的进气室或排气室相连, 进气室和排气室交替排列, 进气室的出气口和排气室的进气口分别与底板上的狭缝相适配, 底板的上 方设置冷却腔, 下方设置石墨块, 相邻的石墨块之间形成与狭缝等宽的进 气通道或排气通道, 进气室的进气口与连接进气管的进气分配器相连通, 排气室的出气口与连接排气管的排气集成器相连通。 在壳体的两端设置挡 帘与上下翻板, 可以起到调节环境气流作用, 通过改变档帘与玻璃带的距 离, 转动翻板的角度, 可以方便地调节外界气流的方向和强度, 从而保证 了镀膜区气流场的稳定; 通过温度监控装置和加热器, 可以使得镀膜区的 温度场均匀合适; 压力调节装置可以保证镀膜区的压力场稳定, 使镀膜器 喷出的镀膜工艺气体不受外界环境影响。 镀膜器中每个进气室和排气室都 是独立单元, 因此根据生产需要可以灵活方便地拆卸和组装, 形成平行的 多进多排的稳定的气流走向, 从而有利于提高镀膜玻璃的质量。 通过改变 底板上狭缝的宽度, 可以方便地调节进气通道和排气通道的宽窄。 而每个 进气室的进气量和每个排气室的排气量都是可调的, 因此膜层厚度调节范 围大, 能满足各种膜厚的生产需要, 可以方便地在线大批量生产低辐射镀 膜玻璃, 大大提高低辐射镀膜玻璃的产品质量和产量。

作为优选, 加热器设置在传送辊的上方, 所述的温度监测装置上设有 红外传感器, 红外传感器设置在壳体顶部。 温度监测装置起到测量和调节 镀膜区温度的作用。
作为优选, 镀膜器的进气室为 2至 6个, 排气室为 3至 7个, 排气室 比进气室多一个, 相邻的进气室与排气室的间隔相等。 进排气室起到控制 工艺气体流量和排气流量, 决定膜厚及膜层均匀性的作用。 本发明的有益效果是: 它有效地解决了现有玻璃镀膜设备存在的镀膜 功能单一、 膜层调节范围小及镀膜质量差的问题。 本发明结构简单, 镀膜 功能全、 膜层厚度调节范围大、 镀膜质量好, 有显著的经济效益。 附图说明
