废弃覆膜砂再生装置
本技术涉及铸造废料回收利用
,具体涉及一种废弃覆膜砂再生装置。
技术介绍
覆膜砂主要采用优质精选天然硅砂为原砂,热塑性酚醛树脂,乌洛托品及增强剂为原料,具有壳型不起层、热稳定性好、导热性好、流动性好、铸件表面平整以及高强度和耐高温的优点,广泛应用于铸造成型工艺中,目前覆膜砂使用完就成为废品扔掉,不环保,如何实现覆膜砂的再生回收成为本行业重点研究的课题。
技术实现思路
本技术提供了一种废弃覆膜砂再生装置,以解决现有技术存在的废弃覆膜砂无法回收利用和不环保的问题。本技术解决其技术问题所采用的技术方案是:一种废弃覆膜砂再生装置,由中频感应燃烧机构、前预热仓、后预热仓、风机、降温床、筛选机和除尘机构组成,中频感应燃烧机构由燃烧炉和中频加热感应器组成,燃烧炉内置不锈钢加热管,前预热仓和后预热仓均具有管壳式结构,前预热仓壳程出口与燃烧炉相通,燃烧炉的气体出口与前预热仓管程进口相连,风机出口与后预热仓的管程进口相连,后预热仓的管程出口与燃烧炉的气体进口相连,燃烧炉的物料出口与后预热仓的壳程进口相连,后预热仓的壳程出口与降温床相连,降温床与筛选机相连,筛选机与外部的混砂机相连,前预热仓的管程出口和降温床的气体出口分别与除尘机构相连。上述筛选机为滚筒筛选机。本技术装置的工作原理:废弃覆膜砂送至前预热仓中,在前预热仓中首先与燃烧炉送来的高温气体换热升温预热,然后废弃覆膜砂再进入燃烧炉中,燃烧炉通过中频加热感应器将不锈钢加热管加热至600℃以上,废弃覆膜砂在燃烧炉中通过后预热仓送来的热风吹起悬浮高温燃烧再生还原成合格的砂料,高温还原的砂料再进入后预热仓中与风机 ...
