Description

一种隧道窑
技术领域
本发明涉及砖瓦机械，尤其涉及一种砖坯烧制的环形的隧道窑。
背景技术
在隧道窑的湿坯进窑烘干时，由于排潮负压，误吸入大量空气，引起脱硫塔排出气体的氧含量超标。另外现有的隧道窑在焙烧的过程中产生大量的热量损耗，保火能力不强，从而造成了能源的损耗。
发明内容
本发明提供了一种隧道窑，本隧道窑预烘干段前进时可伸缩，能使得烟气达到较低含氧量的达标排放；本装置的保火能力显著增强，节能性显著提供。
本发明提供了下述技术方案：一种隧道窑，包括环轨1、与所述环轨1轨道连接的窑室2，所述隧道窑还包括第一闸门3、第二闸门4、第三闸门5、滑动窑室6，所述窑室2依次分段为湿坯烘干段8、干坯预热段9、焙烧段10、保温段11、冷却段12，所述滑动窑室6与所述环轨1轨道连接，所述滑动窑室6可与所述窑室2交错重叠，所述第三闸门5设于所述滑动窑室6的外端，所述第二闸门4设于所述窑室2靠近所述第三闸门5的一端，所述第二闸门4与所述第三闸门5之间的空间为湿坯预热排潮可伸缩段7，余热管道13一端与所述冷却段12连通，所述余热管道13的另一端与所述湿坯预热排潮可伸缩段7连通。
进一步，所述第一闸门3设于所述窑室2中部，所述第一闸门3的两侧分别为所述隔断湿坯烘干段8和所述干坯预热段9。
进一步，所述隧道窑含有内抽风管道14、外抽风管道15，所述内抽风管道14、外抽风管道15合并后送入所述湿坯烘干段8的支管道，所述湿坯烘干段8的所述支管道与排潮管道16连接，所述排潮管道16与地下环形密封通道17连接，所述地下环形密封通道17与脱硫塔18连接。
进一步，所述隧道窑的所述余热管道13通过风机与所述湿坯预热排潮可伸缩段7连接。
本发明的有益效果：本隧道窑包括窑室2、供窑室2旋转的内、外圆形轨道即本申请的环轨1、余热管道13、内抽风管道14、外抽风管道15，旋转式隧道窑的窑室2包括烘干，排潮，预热，焙烧，保温，冷却。本发明在旋转式隧道窑的主体上设计了三个闸门，第一闸门设置在湿坯烘干段8与干坯预热段9分隔处，保证了旋转式隧道窑完成预热、焙烧、保温、冷却的密封性能，不会把湿坯烘干段8的湿汽带入干坯预热段9，影响制品质量，而且保证了旋转式隧道窑需要的保火的功能，杜绝了无风机窑炉无法保火的缺陷。第二闸门4设置在窑室2的靠近第三闸门5的端部，第三闸门5设置在滑动窑室6最前面，确保湿坯预热段的密封，这二道门在焙烧过程中，旋转隧道窑进湿坯时，交替关闭。保证湿坯进窑烘干时，由于排潮负压力误吸入大量空气，引起氧含量超标。焙烧段的烟气通过管道，设置在旋转窑主体的两侧，分别送入烘干段，干燥制品，方便设置的中间闸门。干净的焙烧冷却段余热，用单独管道，加接力风机送往湿坯的预热段，生产的湿坯蒸汽通过风机，进行无公害排放。同时余热管道13循环利用热量达到节能的目的。
附图说明
图1是本发明所述一种隧道窑的结构示意图。
具体实施方式
以下结合附图与具体实施例对本发明作进一步描述。
图1中：环轨1、窑室2、第一闸门3、第二闸门4、第三闸门5、滑动窑室6、湿坯预热排潮可伸缩段7、湿坯烘干段8、干坯预热段9、焙烧段10、保温段11、冷却段12、余热管道13、内抽风管道14、外抽风管道15、排潮管道16、地下环形密封通道17、脱硫塔18。
一种隧道窑，包括环轨1、与所述环轨1轨道连接的窑室2，所述隧道窑还包括第一闸门3、第二闸门4、第三闸门5、滑动窑室6，所述窑室2按照工艺次序依次分段为湿坯烘干段8、干坯预热段9、焙烧段10、保温段11、冷却段12，与依次进行的湿坯烘干、干坯预热、焙烧、保温、冷却的工艺链相一致。
所述滑动窑室6与所述环轨1轨道连接，所述滑动窑室6可与所述窑室2交错重叠，环轨1含有内层轨道和外层轨道，内层轨道和外层轨道均为形如列出轨的双轨结构，内层轨道安装窑室2，外层轨道安装滑动窑室6，使得滑动窑室能与窑室2交错重叠。所述第三闸门5设于所述滑动窑室6的外端，所述第二闸门4设于所述窑室2靠近所述第三闸门5的一端，所述第二闸门4与所述第三闸门5之间的空间为湿坯预热排潮可伸缩段7，随着滑动窑室6的移动可以调节第二闸门4与所述第三闸门5之间的间距，从而实时的改变湿坯预热排潮可伸缩段7的空间大小。余热管道13一端与所述冷却段12连通，所述余热管道13的另一端与所述湿坯预热排潮可伸缩段7连通。
所述湿坯烘干段8位于所述第一闸门3、第二闸门4之间，所述第一闸门3的一侧依次为干坯预热段9、焙烧段10、保温段11、冷却段12，所述第一闸门3设于所述窑室2中部，所述第一闸门3的两侧分别为所述隔断湿坯烘干段8和所述干坯预热段9。第一闸门3起到隔热保火的作用，减少热量的散失。
所述隧道窑含有内抽风管道14、外抽风管道15，所述内抽风管道14、外抽风管道15合并后送入所述湿坯烘干段8的支管道，所述湿坯烘干段8的所述支管道与排潮管道16连接，所述排潮管道16与地下环形密封通道17连接，所述地下环形密封通道17与脱硫塔18连接。通过管道的层层连接最终于脱硫塔中排烟。
所述隧道窑的所述余热管道13通过风机与所述湿坯预热排潮可伸缩段7连接。提供了余热管道气流交换的效率，该余热管道13为利用余热的管道，将窑室2的末段，即冷却段12所冷却散发的热量再次利用，用于最初的湿坯的预热排潮，达到节省能源的目的。
其中与地下环形密封通道17相连接的脱硫塔内置有风机，因此给抽风带来一定的动力，使得管道内形成负压，便于窑室的排潮。排潮过程中第三闸门5为密封关闭状态，送坯过程中第三闸门5打开，滑动窑室6使置于环轨1中间码放的环形的湿坯被送至湿坯预热排潮可伸缩段7中，进入烧砖工艺链。待加工的砖坯固定码放不动，通过窑室内的运动实现砖坯的依次煅烧。在出货时，滑动窑室6不动，使窑室2运动，窑室2运动的同时湿坯预热排潮可伸缩段7空间缩小，那么在窑室2的另一端烧结完成的成品砖块呈现而出，通过该动作完成循环性的湿坯上料、产出成品。
