Description

高温退火环形炉密封砂的清理、筛选及填充装置
相关申请
本申请要求于2023年8月15日递交的申请号为202311028013.5的中国专利申请的优先权，并引用上述专利申请公开的内容作为本申请的一部分。
技术领域
本公开涉及环形炉砂体处理技术领域，尤其涉及一种高温退火环形炉密封砂的清理、筛选及填充装置。
背景技术
取向硅钢高温退火环形炉加热钢卷时，需在钢卷外面加上内罩(用于硅钢环形退火炉钢卷的保护，在超高温介质环境中工作)，而内罩和加热炉台车砌体(用于放置加热钢卷，周边设置有圆形沟槽，用于放置密封石英砂，每处圆形沟槽均放置一个内罩，对应一个钢卷工位)之间需用密封砂(用于内罩与台车砌体之间的缝隙密封，采用符合工作温度、化学成分和密封要求的材料)进行密封。在环形炉每次产出钢卷时，均需将原有密封砂进行表面清理，清理掉表面烧结部分及掉落的氧化铁粉，再填充新的密封砂或筛选过重复利用的密封砂，保持内罩与台车砌体之间的密封效果，进行下一个钢卷的加热循环。
目前密封砂的清理、筛选和填充主要是采用人工劳动操作，操作不便，效率较低，且环境温度较高，对操作人员职业健康安全造成隐患。
现有技术中有吸砂系统和筛分系统，通过硬质吸砂枪吸砂，密封砂流向是：硬质吸砂枪→吸料管→储料罐→振动筛体→输料筒→回填斗。在储料罐与吸风机之间依次安装有旋风除尘器和布袋除尘器，通过两个除尘器对吸入到所述吸风机中的空气进行净化，起到防护吸风机的效果，以保证设备正常工作，同时颗粒较小的密封砂通过两个除尘器也尽可能的清除。该技术方案仅是介绍系统流程和各部分的功能，没有具体的空间布置和设备，该技术有以下几个缺点：
一、无密封砂填充系统，不能实现自动填充密封砂，仍需人工填充。
二、吸砂管需要人工拉扯，不便于操作人员操作。
三、回填斗需要定期运走，不具备连续运行条件。
四、无法清除密封砂中的氧化铁粉。
五、不能形成吸砂、筛选、填充的闭式工作循环，人工劳动强度比较大。
由此，本发明人凭借多年从事相关行业的经验与实践，提出一种高温退火环形炉密封砂的清理、筛选及填充装置，以克服现有技术的缺陷。

吸砂系统2的具体结构如下：
如图1、图3、图5所示，吸砂系统2包括顺序连接的吸砂嘴21、吸砂软管22、旋风除尘器23、负压袋式气固分离器24和空压机25，吸砂嘴21、吸砂软管22构成吸砂部，旋风 除尘器23、负压袋式气固分离器24构成沉积部，密封砂通过安装在工作平台5上的旋风除尘器23完成一次沉积，再经负压袋式气固分离器24完成二次沉积，吸砂系统2实现了密封砂的机械式清理。吸砂软管22的入口通过末端吸砂管28连通吸砂嘴21，吸砂软管22架设于折叠臂13和悬挑旋转臂12上，末端吸砂管28架设于转臂14上，吸砂嘴21能随转臂14、折叠臂13和悬挑旋转臂12运动切换至各台车砌体位置；空压机25旋转使吸砂系统2内产生负压，吸砂嘴21在负压作用下吸收台车砌体处的密封砂，旋风除尘器23对通过吸砂嘴21和吸砂软管22的密封砂进行一次沉积，负压袋式气固分离器24对通过旋风除尘器23的密封砂进行二次沉积。

吸砂系统2是利用空压机25高速旋转使吸砂管路内产生较大的负压，从而带动吸砂嘴21处的密封砂进入吸砂软管22，密封砂被输送至旋风除尘器23内时，由于压力及流速的突然大幅度降低，绝大部分密封砂在旋风除尘器23内沉积；微小颗粒的密封砂在气流带动下，继续向负压袋式气固分离器24流动，并在此处进行沉积降落，可定期卸除袋式除尘器收集的 颗粒微小的密封砂。
