具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的侧吹熔炼炉1。如图1和图2所示，根据本申请实施例的侧吹熔炼炉1包括炉体10、隔墙20、驱动装置60和下烟道30，炉体10包括炉顶110和炉腔120。
隔墙20在第一位置与第二位置之间可上下移动地设置，位于该第一位置的隔墙20的至少一部分位于炉腔120内以便将炉腔120分隔为第一区域121和第二区域122，位于该第二位置的隔墙20的至少一部分位于炉腔120外。驱动装置60能够与隔墙20相连以便驱动隔墙20从该第一位置移动到该第二位置。下烟道30包括第一烟道310和第二烟道320，第一烟道310与第一区域121连通，第二烟道320与第二区域122连通。
其中，驱动装置60能够与隔墙20相连是指：当将隔墙20从该第一位置移动到该第二位置时，驱动装置60与隔墙20相连。换言之，在无需将隔墙20从该第一位置移动到该第二位置时，驱动装置60可以与隔墙20相连，驱动装置60也可以不与隔墙20相连。
在相关技术中，由于侧吹熔炼炉的隔墙位于炉腔内，因此当需要对隔墙进行检修、更换时，操作人员需要进入炉腔内。由此在对隔墙进行检修、更换时，需要先使侧吹熔炼炉停止运行，然后等待侧吹熔炼炉的炉腔冷却至预设温度。例如，侧吹熔炼炉的炉腔冷却至50摄氏度大概需要两周时间。只有当侧吹熔炼炉的炉腔冷却至预设温度后，操作人员才能进入到炉腔内对隔墙进行检修、更换，以便确保操作人员的人身安全。
由于根据本申请实施例的侧吹熔炼炉1的隔墙20能够在该第一位置与该第二位置之间可上下移动，因此在对隔墙20进行检修时，可以使侧吹熔炼炉1停止运行、且将隔墙20从该第一位置移动到该第二位置，以便使隔墙20的至少一部分移动到炉腔120外，这样操作人员可以在炉腔120外对隔墙20进行检修。也就是说，操作人员无需进入到炉腔120内对隔墙20进行检修，这样可以便于操作人员进行与检修相关的操作。
由此无需等炉腔120冷却至预设温度再对隔墙20进行检修，而且隔墙20的位于炉腔120外的部分可以快速冷却，从而只需等较短时间(大概两天)就可以对隔墙20进行检修。由此可以方便地、快速地对隔墙20进行检修。特别是在隔墙20的检修频率较高的情况下，本申请的技术方案更具优点。
根据本申请实施例的侧吹熔炼炉1通过设置在该第一位置与该第二位置之间可上下移动的隔墙20，从而可以方便地、快速地对隔墙20进行检修。而且，由于可以极大地减少对隔墙20进行检修所消耗的时间，因此可以增加侧吹熔炼炉1的运行时间，以便提高侧吹熔炼炉1的产量。
因此，根据本申请实施例的侧吹熔炼炉1具有便于检修隔墙20、隔墙20检修耗时短、 产量高等优点。
如图1和图2所示，在本申请的一些实施例中，侧吹熔炼炉1包括炉体10、隔墙20、驱动装置60和下烟道30。
炉体10包括炉顶110、炉墙130和炉腔120，炉墙130包括在第一水平方向上相对设置的第一炉墙131和第二炉墙132。炉腔120的第一区域121和第二区域122沿第二水平方向排列，该第二水平方向垂直于该第一水平方向。该第二水平方向如图1中的箭头A所示，该第一水平方向如图2中的箭头B所示。
炉体10的与第一区域121相对的部分上设有第一喷枪孔141，炉体10的与第二区域122相对的部分上设有第二喷枪孔142。具体地，炉墙130的与第一区域121相对的部分上设有第一喷枪孔141，炉墙130的与第二区域122相对的部分上设有第二喷枪孔142。炉体10上还可以设有加料口151、观察口152、渣排放口153和金属排放口154。由于这些结构都可以是已知的且与本申请的申请点无关，因此不再详细地描述。
隔墙20在该第一位置与该第二位置之间可上下移动地设置，位于该第一位置的隔墙20的至少一部分位于炉腔120内以便将炉腔120分隔为第一区域121和第二区域122，位于该第二位置的隔墙20的至少一部分位于炉腔120外。
可选地，位于该第二位置的隔墙20全部位于炉腔120外。由此不仅可以方便地、快速地对隔墙20进行检修，而且可以方便地、快速地对隔墙20进行更换。因此，根据本申请实施例的侧吹熔炼炉1还具有便于更换隔墙20、隔墙20更换耗时短、产量高等优点。
隔墙20可以是水冷隔墙。可选地，隔墙20可以是负压水冷隔墙，由此可以有效地延长隔墙20的使用寿命，同时可以避免水管破裂后出现熔体***现象，以便提高侧吹熔炼炉1的安全性。也就是说，对于负压水冷隔墙来说，冷却水套破损后，冷却水不会外溢泄露到高温熔池，从而可以避免重大安全事故发生。
如图1和图2所示，侧吹熔炼炉1进一步包括操作室40，操作室40设在炉顶110上。操作室40独立地限定出操作空间410，或者操作室40与炉顶110之间限定出操作空间410。位于该第二位置的隔墙20的至少一部分位于操作空间410内。通过设置操作室40，从而可以使操作人员在操作室40的操作空间410内进行检修，以便可以进一步确保操作人员的人身安全。
可选地，位于该第二位置的隔墙20全部位于操作空间410内。由此不仅可以更加安全地对隔墙20进行检修，而且可以更加安全地对隔墙20进行更换。
如图1和图2所示，操作室40的至少一部分位于下烟道30内以便将下烟道30分隔为第一烟道310和第二烟道320。由此可以使侧吹熔炼炉1的结构更加紧凑。
如图2所示，可选地，操作室40沿该第一水平方向穿过下烟道30以便将下烟道30分 隔为第一烟道310和第二烟道320。也就是说，操作室40的一部分位于下烟道30内，操作室40具有在该第一水平方向上相对的第一端部和第二端部，操作室40的该第一端部和该第二端部位于下烟道30外。由此便于操作人员进入到操作空间410内。
如图1所示，第一烟道310和第二烟道320沿该第二水平方向排列，操作室40包括沿该第二水平方向相对设置的第一侧壁420和第二侧壁430。其中，第一侧壁420构造成第一烟道310的一个侧壁，第二侧壁430构造成第二烟道320的一个侧壁。由此可以简化侧吹熔炼炉1的结构，降低侧吹熔炼炉1的建造成本。
如图1所示，侧吹熔炼炉1进一步包括上烟道50，上烟道50与第一烟道310和第二烟道320中的每一者连通。由此第一区域121内的烟气可以通过第一烟道310进入到上烟道50内，第二区域122内的烟气可以通过第二烟道320进入到上烟道50内。
通过设置与第一烟道310和第二烟道320都连通的上烟道50，从而可以将第一区域121内的烟气和第二区域122内的烟气汇聚到上烟道50内，以便对烟气进行集中统一地处理。由此可以省掉一套烟气处理***，从而可以降低侧吹熔炼炉1的建造成本和运行成本。
可选地，如图1所示，上烟道50的下端部与第一烟道310和第二烟道320中的每一者的上端部相连。换言之，上烟道50的下端部与第一烟道310的上端部相连，上烟道50的下端部也与第二烟道320中的每一者的上端部相连。由此可以使侧吹熔炼炉1的结构更加合理。
第一烟道310的下端部可以与炉体10的炉墙130相连，第二烟道320的下端部也可以与炉体10的炉墙130相连。此外，第一烟道310和第二烟道320中的每一者的下端部可以设在炉顶110上。
如图1所示，上烟道50包括竖直段510、第一倾斜段520和第二倾斜段530，竖直段510的下端部与第一倾斜段520和第二倾斜段530中的每一者的上端部相连。例如，上烟道50的结构大体与三通管的结构相同，即上烟道50为三通型烟道。其中，第一倾斜段520的下端部与第一烟道310的上端部相连，第二倾斜段530的下端部与第二烟道320的上端部相连。由此可以使上烟道50和侧吹熔炼炉1的结构更加合理。
可选地，如图1所示，操作室40的顶部440构造成棱锥状，操作室40的顶部440包括沿该第二水平方向相对设置的第一斜顶壁441和第二斜顶壁442。其中，第一斜顶壁441构造成第一倾斜段520的一部分，第二斜顶壁442构造成第二倾斜段530的一部分。由此不仅可以简化侧吹熔炼炉1的结构，降低侧吹熔炼炉1的建造成本，而且可以利用第一斜顶壁441和第二斜顶壁442对烟气进行导流。
如图1所示，第一炉墙131具有第一容纳槽，第二炉墙132具有第二容纳槽，隔墙20具有在该第一水平方向上相对的第一端部210和第二端部220。其中，位于该第一位置的 隔墙20的第一端部210的至少一部分位于该第一容纳槽内，位于该第一位置的隔墙20的第二端部220的至少一部分位于该第二容纳槽内。由此可以进一步提高第一区域121和第二区域122各自的独立性，更加有效地实现同一侧吹熔炼炉1内不同气氛的控制，更加有利于实现一炉两用，以便降低设备投资、减少能源消耗、提高生产作业率。
可选地，该第一容纳槽的壁面与位于该第一位置的隔墙20的第一端部210的该至少一部分之间设有第一密封层，该第二容纳槽的壁面与位于该第一位置的隔墙20的第二端部220的该至少一部分之间设有第二密封层。由此可以进一步提高第一区域121和第二区域122各自的独立性，更加有效地实现同一侧吹熔炼炉1内不同气氛的控制，更加有利于实现一炉两用，以便降低设备投资、减少能源消耗、提高生产作业率。
例如，该第一密封层可以是石棉层，该第二密封层可以是石棉层。该第一密封层可以设在该第一容纳槽的壁面上，也可以设在隔墙20的第一端部210的该至少一部分上；该第二密封层可以设在该第二容纳槽的壁面上，也可以设在隔墙20的第二端部220的该至少一部分上。
如图1所示，驱动装置60设在操作空间410内，驱动装置60包括滑轮支架610、滑轮、绳索和驱动器。滑轮支架610设在操作室40内，该滑轮设在滑轮支架610上。该绳索绕过该滑轮，该绳索的第一端部210与隔墙20相连。该驱动器与该绳索的第二端部220相连以便通过该绳索驱动隔墙20在该第一位置与该第二位置之间移动。可选地，该驱动器为卷扬机或手提葫芦。由此可以方便地、快速地在该第一位置与该第二位置之间移动隔墙20。
