摘要
随着石油化工装置规模的大型化,原、燃料煤卸煤、储存及输送的需求也越来越多,破碎机的处理量也越来越大。工艺专业选用的破碎机有:可逆锤击式细碎机、四齿辊粒式破碎机、环锤式碎煤机等。目前结构专业的破碎机支承方式有3种:破碎机基础与主结构脱开的独立框架式基础;破碎机直接支承在结构梁板上的形式;在破碎机支承结构与梁、板之间减振阻尼的形式。通过实际工程项目,采用YJKS中的楼板及设备振动程序、Bentley公司的STAAD.Pro软件,建模计算分析结构设计中支承破碎机的3种方式,提出更合理、适用的支承方案。
With the increase in capacity of petrochemical plant in recent years,there are more and more coal unloading,storage and conveying systems for raw coal and fuel coal,and the processing capacity of crusher is increasing.The crushers selected by the process discipline include reversible hammer type crusher,four teeth roll type crusher,ring hammer type crusher,etc.At present,there are 3 methods for supporting the crusher,i.e.the independent frame foundation that separates the crusher foundation from the main structure,the crusher directly supported by beam-slab structure,and the design of damping between crusher supporting structure and beam-slab structure.These 3 methods for supporting the crusher have their own application scopes and advantages and disadvantages.Relevant specifications and design manuals have different requirements for the three supporting methods.A more reasonable and applicable supporting scheme is to be put forward by modeling,calculating and analyzing the 3 supporting methods using the floor and equipment vibrating program of YJKS and the STAAD.Pro software of Bentley based on actual engineering projects.
