Description

一种自屏蔽加速器及利用该加速器的PET塑料瓶生产线
本申请要求2015年09月11日提交中国专利局、申请号为201510576112.6、发明名称为“一种自屏蔽加速器及利用该加速器的PET塑料瓶生产线”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及了一种自屏蔽加速器及利用该加速器的PET塑料瓶生产线，属于加速器辐照设备技术领域。
背景技术
PET饮料瓶无菌灌装的关键技术之一是灭菌处理，它是无菌灌装成败的关键所在。灭菌范围包括包装材料(PET瓶和盖)。传统的灭菌处理方法一般为化学方法，利用强氧化剂的氧化能力与细菌酶蛋白质的分子结构，干扰细菌酶系统的代谢，使其失去活性。目前常用的药剂为双氧水、过氧乙酸、二氧化氯溶液和消毒液等。使用化学方法灭菌存在几大缺点：
1、化学药剂会对容器和包材以及设备产生一定量的残留污染，必须采取严格的措施控制残留，以保障最终产品的安全性；
2、使用化学药剂伴随着大量的水的消耗，还有环境的影响，另外还需要有化学药品站的配套。
而辐射灭菌是利用电磁辐射产生的电磁波杀死大多数物质上的微生物的一种有效方法。在辐照过程中，电子束、X射线或γ射线，作用于微生物，直接或间接破坏微生物的核糖核酸、蛋白质和酶，从而杀死微生物，起到消毒灭菌的作用。辐照灭菌是一种无污染、无残留的灭菌方式，是一种绿色环保技术。尤其是电子束灭菌，电子束由电子加速器产生，本身不含有放射源，相对钴60更安全，从灭菌剂量上来说，电子加速器提供的剂量更准确，也是今后辐照灭菌的发展方向。
鉴于辐射灭菌法的这些优点，可以很好的解决采用化学灭菌法的诸多问题。因此利用辐射灭菌法替代化学灭菌法的想法也被许多PET瓶灌装生产线企业所重视并在不断探索这种替代方法的可行性。而以前受限于电子 加速器制造技术水平，加速器本体都比较庞大而且需要有建筑屏蔽，要应用在生产线上几乎是不可能的。而随着这几年电子加速器制造技术突飞猛进的发展，低能电子加速器逐渐趋向自屏蔽和小型化设计使辐射加工的在线化(可以安装在生产流水线上)成为可能。
目前，市场上还未有相关产品，为了进一步推进节能环保工作，灌装线生产企业迫切的想要开发出使用电子束技术进行PET瓶灭菌技术的生产线。
发明内容
本发明所要解决的技术问题是提供一种自屏蔽加速器及利用该加速器的PET塑料瓶生产线，采用了全卧式自屏蔽结构，并能与灌装生产线实现无缝对接，使辐射加工的在线化成为可能。
为了解决上述技术问题，本发明所采用的技术方案是：
一种自屏蔽加速器，包括加速器组件、高频电极板、整流倍压组件、螺线管变压器组件、冷却系统组件和屏蔽钢筒，还包括与所述屏蔽钢筒相连接的钢筒底座，所述加速器组件水平固定在所述钢筒底座上，所述整流倍压组件通过支撑板固定在所述钢筒底座上，所述高频电极板和螺线管变压器组件通过多根水平设置的支撑柱连接在所述钢筒底座，所述冷却系统组件固定在所述屏蔽钢筒上。

优选地，所述屏蔽钢筒的其中一个底脚上还设置有电动开合组件。

一种利用前述自屏蔽加速器的PET塑料瓶生产线，包括灌装生产线，所述灌装生产线与自屏蔽加速器之间设置有扫描盒，所述扫描盒与灌装生产线的辐照腔之间采用台阶面进行无缝连接。
本发明的有益效果是：
1.本发明提出了一种嵌入式自屏蔽结构理念，实现设备与整个灌装生产线的无缝对接，本发明自屏蔽加速器的扫描盒是直接与生产线上的开口面对接的，这样可以确保辐射剂量不会泄漏，保证了产品的安全性。
2.本发明提出了一种全卧式结构，其把加速管及束流引出部分整合到整流倍压组件内，由原来分开的加速管钢筒和高压电源钢筒整合为一个加速器钢筒，同时对此钢筒的屏蔽也做了增强处理，不仅大大节省了空间，还兼顾了辐射防护要求。
3.本发明提出了一种新的卧式安装结构，其设置了四根支撑柱，这四根支撑柱固定在钢筒底座上，而高频电极板、螺线管变压器等原固定在加速器主钢筒上的部件现分别依靠这四根支撑柱固定，其优点是结构更简单、维修方便，这种方式所有的关键部件都集中固定钢筒底座上了，维修时只要打开主钢筒就能检查和维护这些关键部件。
4.本发明采用的屏蔽结构分两部分，一部分为束流扫描系统部分，其与灌装生产线相连，确保设备与生产线的无缝对接；另一部分为加速器主体屏蔽部分，屏蔽体采用全钢结构，并且这两部分可通过钢筒电动开合机构实现主钢筒及屏蔽体的电动开合，具有体积小、屏蔽效果好、操作简单等优点，同时也大大增加了安装维护的便捷性。
5.本发明优化了自动化控制系统，采用了一键式操作模式，优化了设备的整体操作性，操作简单、安全可靠、自动化程度高，大大降低了对操作员的要求。
