Design Transformation Of Chain Bucket Continuous Ship Unloader

There are two chain bucket continuous ship unloaders in Ore Terminal Phase II of the Tangshan Caofeidian Shiye Port CO.,LTD.The unloading efficiency of these devices can be achieved 3800t/h.These chain bucket continuous ship unloaders are the first batch of domestic independent design productions which applied to large specialized wharf.Even though many key parts of the chain bucket ship unloader had carried on the reform and innovation on the basis of the experience and lessons in absorbing foreign related enterprises,but when the equipment put into normal production there is still a lot of new problems inevitably.So many feasible reconstruction designs are carried out to resolve the parts that failure rate is relatively high.Thus the reliability and unloading efficiency of the chain bucket continuous ship unloader is enhanced.Firstly,this paper expound Chain bucket continuous ship unloader's key components of the structure and function in detail include the Cart walking mechanism,the Output belt conveyor,the Boom belt conveyor and so on.Then made the deeply study of the Chain bucket continuous ship unloader's Characteristic organization and principles of unloading.Secondly,In the process of operation,this paper made an analysis for malfunction form and malfunction reason of the frequent malfunction parts,rotary feeder,(Bucket Elevator,abbreviated name BE)excavation section,blanking recovery device.Combined with the actual conditions of the site,put forward a practical transformation program,and made a specific analysis for the transformation effect and benefit.After the transformation,the chain bucket continuous ship unloader is able to meet the needs of the scene.The failure rate and maintenance time and maintenance cost is reduced.Thus the unloading efficiency of the chain bucket continuous ship unloader and the company's competitiveness is enhancedThere is a systematic management maintenance and reconstruction design of key components for 3800t/h chain bucket continuous ship unloader.And it also provides valuable experience of domestic chain bucket continuous ship unloader for the application of Large-scale Specialized Ore Terminal.
