Description

一种可分段控温的回转炉窑 技术领域
本发明涉及一种炉窑，具体地说是一种可分段控温的回转炉窑。
背景技术
在建材、冶金、化工、环保等许多生产行业中，广泛使用回转圆筒设备对固体物料进行机械、物理或化学处理，这类设备被称为回转窑，其技术性能和运转情况，在很大程度上决定着企业的产品质量和生产成本。现有回转窑的结构如图8所示。
窑体由托轮支撑，驱动装置带动窑体围绕其轴线做回转运动。燃烧器位于窑体的一端，为窑体内温度场的建立提供所需的热量。物料从加料口加入窑体内，随着窑体的转动物料在窑体内一边被抛撒、翻滚，一边沿窑体轴线向出料端运动，同时物料在热作用下发生物理、化学或物料化学变化。由于燃烧器位于窑体的一端，当窑体较长时，窑体内长度方向各段的温度控制比较困难，很难同时兼顾设备生产率、窑体内温度分布及烧成气氛等因素，从而使得单位窑体断面积生产率较低，单位产成品能耗高。
为了解决这一问题，专利号为2017218534981的专利公开了一种摆动窑炉，该窑炉通过将燃烧器设置在窑体的侧壁上，虽然解决了控温不精准的问题，但是窑体只能够做摆动，而无法回转，在使用上受到很大的限制。
发明内容
针对上述问题，本发明提供了一种可分段控温的回转炉窑，该炉窑不仅能够实现分段控温，使窑体内温度场的控制更加精准，而且能够实现回转，与传统回转炉窑相比应用范围更加广泛。
本发明解决其技术问题所采取的技术方案是：
一种可分段控温的回转炉窑，包括窑体、窑头罩、窑尾罩和底座，所述的底座和窑体之间设置有驱动装置，还包括由供给段、连接段和转动段组成的第一燃料供给管，所述的供给段固定设置于所述窑体的外侧壁上，所述的转动段与所述窑体同轴布置，并通过旋转接头与燃料供给源相连，所述的供给段和转动段通过连接段相连通；
所述窑体的外侧壁上设置有多组燃烧组件，且所述燃烧组件的燃料进口分别通过支管与所述第一燃料供给管的供给段相连。
进一步地，所述的燃烧组件包括烧嘴，所述烧嘴的燃料进口通过支管与所述第一燃料供给管的供给段相连，所述烧嘴的空气进口与风机相连。
进一步地，设置于所述窑体侧壁上的烧嘴砖高出所述窑体的内侧壁。
进一步地，所述的支管上设置有阀门。
进一步地，所述的窑体上设置有轮带和从动齿圈，所述的轮带和从动齿圈上均设置有容许所述供给段通过的通孔。
进一步地，所述的转动段设置于所述窑体的进料端，且所述连接段的一端与所述的转动段相连，所述连接段的另一端穿过所述窑体的侧壁后与所述的供给段相连。
进一步地，所述的转动段设置于所述窑体的出料端。
进一步地，所述的连接段设置于所述的窑头罩内，且所述供给段的端部延伸至所述的窑头罩内与所述的连接段相连。
进一步地，所述的连接段沿径向布置。
进一步地，所述的窑体内设置有间隔布置的第一耐火砖和第二耐火砖，且所述的第一耐火砖和第二耐火砖共同形成了齿形结构。
本发明的有益效果是：
1.将多组燃烧组件设置在窑体的侧壁上并沿轴向分布，使窑体内温度场及气氛的控制更加方便简洁，控制精度得到了提高。
2、可以根据窑体内温度场控制的需要调整燃烧组件的数量、间距以及燃料的流量，从而以最小的能耗达到要求的温度场，兼顾设备的生产率、窑内温度分布及烧成气氛等的要求，提高了单位断面窑体生产率，降低了单位产成品的能耗。
3、该炉窑既可以实现摆动也可以实现回转运动，可以满足不同物料煅烧的工艺要求，与传统的回转炉窑相比，应用范围更加广泛。

具体实施方式
实施例一
如图1所示，一种可分段控温的回转炉窑包括窑体1，所述窑体1的左端设置有窑尾罩2，所述窑体1的右端设置有窑头罩3。所述窑体1的下方设置有底座4，且所述的底座4和所述的窑体1转动连接。
作为一种具体实施方式，本实施例中所述的窑体1上至少设置有两个轮带14，所述的底座4上位于每个轮带14的下方均对称设置有两个用于承托所述窑体1的托轮41，所述的轮带14压紧在所述的托轮41上。
所述的窑尾罩2上设置有进料口21，且所述进料口21通过导料管22与所述的窑体1相连通，所述的导料管穿过所述的窑尾罩2延伸至所述窑体1的内部。所述的窑头罩3的下端设置有出料口31。
如图4所示，所述的窑体1内设置有间隔布置的第一耐火砖11和第二耐火砖12，且所述的第一耐火砖11和第二耐火砖12共同形成了齿形结构。
所述的底座4和窑体1之间设置有用于驱动所述窑体1转动的驱动装置。如图1所示，所述的驱动装置包括电机53、减速机54、驱动齿轮51和从动齿圈52。所述电机53的输出轴与所述的减速机54的输入轴相连，所述减速机54的输出轴与所述的驱动齿轮51相连，与所述驱动齿轮51相啮合的从动齿圈52设置于所述的窑体1上。优选的，所述的驱动齿圈52设置于所述窑体1的中部。
如图1、图3和图6所示，所述窑体1上设置有第一燃料供给管7，所述的第一燃料供给管7包括供给段71、连接段72和转动段73。其中所述的供给段71固定设置于所述窑体1的外侧壁上，且所述的轮带14和从动齿圈52上均设置有容许所述供给段71穿过的通孔。所述的转动段73设置于所述的窑尾罩2内，并与所述窑体1同轴布置，所述的转动段73向左穿过所述的窑尾罩2延伸至所述窑尾罩2的外部。所述的连接段72设置于所述窑体1的内部，且位于所述导料管22的一侧，所述连接段72的一端与所述的转动段73的端部相连，所述连接段72的另一端穿过所述窑体1的侧壁后与所述供给段71的端部相连。优选的，所述的连接段72沿径向布置。
所述第一燃料供给管7的转动段73通过旋转接头9与燃料供给源8相连。在这里所述旋转接头9的结构为现有技术，在此不再赘述。
如图1所示，所述窑体1的外侧壁上沿轴向设置有多组燃烧组件6，作为一种具体实施方式，本实施例中所述窑体1的外侧壁上设置有四组燃烧组件6。所述燃烧组件6的燃料进口分别通过支管62与所述第一燃料供给管7的供给段71相连。所述燃烧组件6的喷口穿过所述窑体1的侧壁延伸至所述窑体1的内部。
在这里，所述的支管62可以为软管或硬管。
如图2和图5所示，所述的燃烧组件6包括固定设置于所述窑体1上的烧嘴61，所述烧嘴61的燃料进口通过支管62与所述第一燃料供给管7的供给段71相连，且所述的支管62上设置有用于控制燃料流量的阀门64。所述烧嘴61的空气进口与风机63相连。
在这里，所述的燃烧组件6也可以采用一体式燃烧机。但是作为一种最优的实施方式，本实施例中所述的燃烧组件6采用组合式结构，主要是因为在工作的过程中燃烧组件6会随着窑体1一起转动，因此燃烧组件6的体积越小越好。若采用一体式燃烧机，回转半径较大，需要根据燃烧机的尺寸对其他部件的尺寸做适应性的调整，例如增加底座4高度等，这样会增大整体设备的结构尺寸。
进一步地，为了避免工作时窑体1内物料堵塞烧嘴61，确保烧烧器的正常工作，如图5所示，设置于所述窑体1侧壁上的烧嘴砖13高出所述窑体1的内侧壁。在这里所述的烧嘴砖13及其安装结构属于现有技术，在传统炉窑中也有应用，在此不再赘述。

进一步地，由于工作时，所述窑体1内的温度进料端低于出料端，而当 所述的转动段73设置于所述的窑头罩3内时，若仍然将所述的连接段72设置于窑体1内，高温环境下存在安全隐患。为此，如图7所示，所述的连接段72设置于所述的窑头罩3内，且所述连接段72的一端与所述转动段73的端部相连，所述连接段72的另一端与所述供给段71的端部相连，所述供给段71的端部延伸至所述的窑头罩3内。优选的，所述的连接段72沿径向布置。其余结构同实施例一。
