Description

高炉受料罐装料装置 技术领域
本发明涉及一种高炉串罐无料钟炉顶装料设备，特别涉及一种受料罐料流分配装置，用于将进入无料钟装料系统中的物料在受料罐中进行分布。
 背景技术
为了解决进入高炉装料系统物料的偏析现象，在物料进入高炉串罐无料钟装料系统前都会采取对物料进行重新分配，确保进入装料系统料罐内物料的均匀性，避免物料偏析对高炉布料的影响，造成高炉炉内物料粒度分布不均，影响高炉上升煤气分布。
现有技术中，高炉炉顶串罐无料钟装料设备采用旋转料罐装置或固定分配器对料流进行二次分配。
旋转料罐装置，是在高炉受料罐上方与上料主皮带头轮罩出料口之间设置一旋转料罐，通过旋转料罐的旋转运动，将物料成环形分布在串罐无料钟受料罐中，由于上料批重较大旋转料罐直径较大，装料多，自重大，因此旋转料罐的旋转机构采用圆周方向设置滚轮和滚道作为旋转支撑，其驱动采用销齿传动。旋转料斗装置能够解决物料二次分配的问题，但是整个装置高度大，体积大，重量大，一方面增加了整个炉顶装料系统的高度，增加了炉顶装料设备的负载；另一方面该旋转料罐在运行时，圆周方向不易密封，造成粉尘泄漏，污染环境。
为了减少高炉炉顶串罐无料钟装料设备的高度，目前多采用固定分配器对料流进行二次分配。在串罐无料钟装料设备上部受料罐的顶部安装一固定分配器，其结构特点为：分配器进料口与上料主皮带头轮罩出料口连接，分配器设置4个出料口，间隔90°分布。进入分配器的物料被分成4股料流进入受料罐中，在受料罐中形成4个料堆，减轻了受料罐中的物料偏析现象。固定分配器安装在受料罐内，减少了串罐无料钟装料系统的高度，但是物料分配由原来的环形分配变成了4个料堆分配，其物料粒度二次分配效果减弱。
并且现有技术中，旋转料罐装置和固定分配器的结构都是整体式的，其安装和维修工作都较困难，同时旋转料罐装置和固定分配器与物料接触的料斗部分寿命较短，料斗损坏后需要整体更换旋转料罐装置或固定分配器，使用成本较高。
因此需要开发一种体积小、结构简单、物料分配均匀和便于拆装和维修的高炉装料装置。
