近年来,北方重工集团有限公司矿山机械分公司了完成年产200万t链篦机升级改造的详细技术方案。该方案的升级改造主要体现在以下几个方面:为有效克服热膨胀对驱动部位受热后造成的轴向和径向跳动,采用了双边柔性传动方式,从而改善驱动部位在生产过程产生的振动;根据对热风量的计算,降低罩体高度;将铲料水冷梁由原来的钢管改为钢板焊接结构,取消铲料板支撑梁,实现了材料的节约;针对链篦机工作环境恶劣,增加下回程密封结构,大大降低了设备在实际生产过程中的粉尘排放,降低了污
In recent years, North Heavy Industries Group Co., Ltd. Mining Machinery Branch completed an annual output of 2 million t grate upgrading of the detailed technical solutions. The upgrade of the program is mainly reflected in the following aspects: In order to effectively overcome the thermal expansion of the driving parts after the heat caused by axial and radial run-out, the use of bilateral flexible transmission, thereby improving the driving part of the vibration generated in the production process; According to The calculation of hot air volume, reduce the height of the cover; the shovel water cooled beam from the original steel to steel welding structure, remove the shovel plate support beam, to achieve material savings; grate for the harsh working environment, increase the next back Sealed structure, greatly reducing the equipment in the actual production of dust emissions and reduce pollution
