Description
技术领域
本发明涉及一种陶瓷管烧成装置,尤其涉及一种陶瓷管电加热烧成装置及工艺。
背景技术
针对传统陶瓷管烧成工艺,国内目前使用的工艺是传统窖炉,窖炉主要由耐火砖砌筑而成,装窖时用刚玉架子砖作为支撑和隔焰,产品在架子砖内吊装,燃烧系统由助燃风机,排烟风机和燃气(液化气或天然气)组成,助燃风和燃气混合通过烧嘴燃烧向室内喷火,排烟机将燃烧后的废气排到空中,陶瓷管的烧结是通过火焰的加热(对流辐射传导来完成的)
采用传统窖炉这种方式,存在以下一些缺点:由人工控制烧成,按烧成制度进行,不能实行自控;采用气体做燃料,窖炉内不能做到温度均匀,上下温度同截面水平温度差在20摄氏度以上,不能做到自动控制,质量难以做到均匀一致;因为是在高温阶段1700摄氏度左右的高温高压环境下进行的,存在一定的安全隐患;排出的燃烧废气中有氮氧化合物不利于环保;由于是隔焰烧成(产品不能直接和火接触,否则会掉下来),大量的热量由架子砖和窖体吸收,浪费能源,能效比低。
发明内容
为了解决上述的问题,提供一种全自动、环保节能、安全可靠的陶瓷管电加热烧成装置,技术方案如下:
一种陶瓷管电加热烧成装置及工艺,包括窖体、支架和加热装置,加热装置为电发热体设置在窖体内壁四周,支架由垂直设置的立柱和水平设置在其上的挂架组成,立柱之间留有空隙。
窖体内壁设置有隔热层。
隔热层为轻质纤维块。
电发热体为硅钼棒。
立柱垂直设置在窖车上。
窖体为一端开口的中空结构。
整个陶瓷管生产加工流程为:原料制备——成型——干燥——烧成——检测——加工包装,其中烧成工艺是最核心的部分,可以根据陶瓷管的材质不同,而设置不同的最高温度和保温时间,
一种陶瓷管电加热烧成工艺,包括如下步骤:
(a)将陶瓷管放入窖体中;
(b)将最高温度设置为1700℃± 50℃,开始进行加热;
(c)将温度保持在最高温度4-20小时;
(d)停止加热,待陶瓷管冷却后,从窖体中取出。
与现有技术相比,本发明的有益效果:可以根据材质和厚度,由电脑自动控制来调整加热时间和温度,能保证窖体内温度一致,控制精确,节省人工,安全可靠,可以一窖多用,适用范围广,而且由于采用电加热方式,不会产生燃烧废气,清洁环保,通过电发热体直接辐射产品,降低能源损耗。
附图说明
图1为本发明的剖面结构示意图;
图中,1、窖体,2、窖车,3、立柱,4、电发热体,5、挂架,6、陶瓷管。
具体实施方式
实施例1
如图1所示,使用时,将陶瓷管6悬挂放置在挂架5上,然后窖车2移动至窖体1开口处,通过控制柜操控,将陶瓷管6和支架完全罩住,使窖体1与窖车2组成密封空间,此时通过控制柜设定温度,硅钼棒接通电源后开始发热,窖体1采用轻质纤维块做为隔热层,具有耐高温,蓄热少的特点,可以保证热量不会过多被窖体1吸收,同时相邻立柱3中间留有空隙,热量可直接辐射陶瓷管6,提高效率,节省时间,烧成制度的完成是通过程序根据载入的温度曲线来调节电流和电压的大小来完成,自动控制,节省人工,控制精准。
实施例2
一种陶瓷管电加热烧成工艺,包括如下步骤:
(a)将管壁厚度为2毫米的陶瓷管6放入窖体1中,陶瓷管6为85%含量的氧化铝材质制成;
(b)将温度设置为1650℃;
(c)将温度保持在最高温度4小时;
(d)停止加热,待陶瓷管6冷却后,从窖体1中取出。
实施例3
一种陶瓷管电加热烧成工艺,包括如下步骤:
(a)将管壁厚度为6毫米的陶瓷管6放入窖体1中,陶瓷管6为95%含量的氧化铝材质制成;
(b)将温度设置为1700℃;
(c)将温度保持在最高温度12小时;
(d)停止加热,待陶瓷管6冷却后,从窖体1中取出。
实施例4
一种陶瓷管电加热烧成工艺,包括如下步骤:
(a)将管壁厚度为10毫米的陶瓷管6放入窖体1中,陶瓷管6为99%含量的氧化铝材质制成;
