具体实施方式
下面结合附图对本发明的实施例做进一步描述：
如图1、图2、图3和图4所示，本发明所述的全新的隔焰烧成间歇式窑炉结构，包括窑体1，窑体1内衬为耐火材料5，该材料具有足够高的荷软温度和较好的热稳定性，能够满足该窑炉内衬选材的要求，窑体1外壳为型钢结构6外蒙钢板7，结构稳固，密封性好，窑体1内设有气氛室2，气氛室2由隔焰墙3围成侧壁，气氛室2由窑顶形成气氛室2的顶，窑体1顶部设有排烟孔10，排烟孔10处设有排烟风机，气氛室2底部设有窑车底座8，窑车底座8上装有窑车，要彻底做底部设有升降装置，窑体1上设有煅烧嘴15。将气氛室2与窑体1设计为一体，为保证密封，将原有的水平出车，改为上下出车，使每次烧制不需要重新的破坏并堆砌气氛室2，大大的提高了生产效率，且气氛室2设置于窑体1内，所以其容积不会仅限于窑车的齿轮，使窑车可携带更多原料并一次性烧成更多产品，再次提高了生产效率。
所述的全新的隔焰烧成间歇式窑炉结构，窑车底部设有氮气进气通道，排气通道、测压通道和测温通道，测温通道设有温度传感器13，进气通道设有线性调节阀16，测压通道内设有压力传感器12，排气通道上安装有电磁阀17，窑体1外设有控制装置14，压力传感器12和温度传感器13连接到控制装置14的信号接收端，控制装置14的信号输出端连接到线性调节阀16和电磁阀17的控制端，控制装置14通过压力传感器12的压力信号控制线性调节阀16和电磁阀17的开闭。因通气管路经受窑炉的高温,所以窑车预埋管路采用抗高温材料。进气管路安装流量计以便观察氮气流量，窑车下端管路与窑体1外管路采用金属软管联接，窑车进出运动时可实现快速拆接。每个密封氮化窑池设测压管路，外接压力传感器12，通过线性调节阀16自动调节进氮气流量，以维持密封氮化窑池内氮气压力稳定。控制装置14根据压力传感器12反馈的窑池内的压力变化，控制电磁阀17的开闭，具体控制方法为，当窑池内氮气压力过高时电磁阀17自动打开放散(+20Pa以上)；当用氮气置换氮化窑池内空气时，电动执行阀根据预先设定的置换程序自动反复打开排空。
所述的全新的隔焰烧成间歇式窑炉结构，为保证氮化窑池良好的密封性能，窑车的窑池材料采用重质凸凹槽异形砖，窑池侧墙设1个可拆砌的装卸料口，以方便装料及卸料。密封氮化窑池顶部用重质盖板密封。窑车耐火材料5用耐火胶泥砌筑。
所述的全新的隔焰烧成间歇式窑炉结构，隔焰墙3上设有排烟孔10，隔焰墙3与窑体1外壳之间设有侧壁烟道4，窑顶内部设有顶部烟道9，侧壁烟道4与顶部烟道9之间设有通孔11，排烟孔10与顶壁烟道连通。形成的烟尘经侧壁烟道4后汇集于顶部烟道，并由排烟风机抽出。
所述的全新的隔焰烧成间歇式窑炉结构，窑车上设有辅助加热系统，辅助加热系统为窑车提供辅助加热。
所述的全新的隔焰烧成间歇式窑炉结构，升降装置包括液压缸和提供液压的液压缸泵站，液压缸的活塞杆连接到窑车底座8，液压缸的腔室连接到液压缸泵站。液压缸在设备安装上采用倾斜放置法,有效地避免了安装引起的设备晃动。液压站为集成泵站，选用精磨专用液压油缸，它将平台所用的单向阀、溢流阀、电磁阀17集成为一体，在保证使用性能的前提下使其结构更加紧凑，有效地减少泄露；另外它配备的截止阀可使在意外停电的情况下仍能将窑车底座8落下来。
所述的全新的隔焰烧成间歇式窑炉结构，气氛室2内设有热电偶，热电偶位于煅烧嘴15对面，热电偶的信号输出端连接到控制装置14的信号接收端，控制装置14的信号输出端连接到煅烧嘴15的控制端。
