Description

说明书 发明名称:一种复合陶瓷纤维预制组件
技术领域
[0001] 本实用新型属于工业用加热炉、 保温炉的附件领域, 具体是一种复合陶瓷纤维 预制组件。
背景技术
[0002] 在各种高温窑炉的保温层等处, 现在采用的方式是将耐热材料整体依次呈 "之" 字状对折压缩后构成模块结构, 然后再依次安装到窑炉内, 来取代传统的浇注 加工, 因该结构形式的安装施工、 维修速度块, 节能效果明显, 因此迅速得到 大范围的推广应用。 但在使用企业长吋间的使用过程中, 发现该结构的模块由 于均为高温纤维模块, 而炉内非耐热面不需如此高的耐温, 在设备维护吋又需 一次性将使用过的模块体处理掉, 因此使用成本较高。
技术问题
[0003] 申请号为 201320044504.4的中国专利公幵了一种梯度绝热耐火材料, 属于绝热 耐火材料技术领域, 包括耐火层、 高温绝热层、 中温绝热层、 连接筋, 所述高 温绝热层两侧分别附着耐火层、 中温绝热层, 并通过连接筋固定连接, 由于由 不同的功能层组成, 每一部分都赋予了独特的功能, 且各自发挥其优点。 但这 种通过连接筋固定连接的方式, 无法应用在具备弹性的陶瓷纤维材料上, 工字 筋无法勾住分级温度不同的陶瓷纤维层。
问题的解决方案
技术解决方案
[0004] 申请号为 200720028102.X的中国专利也公幵了一种陶瓷纤维复合模块, 其技术 要点在于模块体由高温纤维毯及低温纤维毯复合为一体, 对折后压缩为一个单 元块, 其中高温纤维毯位于低温纤维毯的外侧, 每个模块体由至少 1个单元块构 成, 模块体的对折面两端加装保护夹板, 在模块体及夹板的外表面加装捆扎带 , 并在模块体上设置固定锚固件。 但这种方式首先需要所述高温纤维毯及低温 纤维毯为整张的一体式结构, 然后才能够对折, 制作工序复杂; 低温纤维毯位 于高温纤维毯对折构成的凹槽内, 针对模块体的非耐高温面采用了低成本的低 温陶瓷纤维毯, 这种变化幅度小频率快, 但实际炉温变化是渐变式的, 越接近 炉心温度越高, 越到炉壁温度越低。 这就需要对现有技术进行进一步改进, 以 降低使用者的使用成本。
