Description

节能高效还原海绵铁隧道窑
技术领域
本实用新型涉及一种还原海绵铁的生产设备，特别涉及一种节能高效还原海绵铁隧道窑。
背景技术
传统的隧道窑是单方向进，单方向出，前面有预热段，中间有加热还原段，尾部有冷却段；冷却段的热量白白浪费掉，浪费了大量能源，冷却速度慢，生产效率低；它占地面积大。
发明内容
本实用新型的目的是提供一种节能高效还原海绵铁隧道窑，它取消了传统的预热段，利用冷却段的余热对需要预热的物质进行预热，这样节省了大量的能源，提高了生产效率；而且占地面积小。
节能高效还原海绵铁隧道窑，它包括窑体，密封保温门，热电偶，封砂槽Ⅰ、封砂槽Ⅱ、封砂槽Ⅲ和封砂槽Ⅳ；所述的窑体包括冷却预热段和加热还原段烧嘴；所述的窑体内设有导轨Ⅰ、导轨Ⅱ、导轨Ⅲ和导轨Ⅳ，所述的导轨Ⅳ设置在导轨Ⅰ、导轨Ⅱ和导轨Ⅲ的端头。
本实用新型的有益效果，节能高效还原海绵铁隧道窑，所述的窑体包括冷却预热段和加热还原段，它利用冷却段的余热对需要预热的物质进行预热，需要预热的物质从导轨Ⅱ进来，走到加热还原段进行加热还原，然后通过导轨Ⅳ送到导轨Ⅰ和导轨Ⅲ上，到达冷却预热段进行冷却，冷却的物质散发的热量正好用来对需要预热的物质进行预热，节省了大量能源，提高了生产效率；因为冷却预热均在窑体内进行，不需要在窑体外再设置导轨进行冷却，所以它占地面积小。
附图说明
图1为本实用新型的结构示意图。
图2为A-A剖视图。
具体实施方式
如图1-2所示，节能高效还原海绵铁隧道窑，窑体1包括冷却预热段12和加热还原段11，密封保温门14设置在窑体1的两端；窑体1上设有若干个烧嘴2和热电偶3，窑体1内设有导轨Ⅰ5、导轨Ⅱ7、导轨Ⅲ9、导轨Ⅳ13、封砂槽Ⅰ4、封砂槽Ⅱ6、封砂槽Ⅲ8和封砂槽Ⅳ10，所述的导轨Ⅳ13设置在导轨Ⅰ5、导轨Ⅱ7和导轨Ⅲ9的端头。
