Description

一种核级锆板或锆管专用的连续热处理炉 技术领域
本发明属于热处理设备领域，具体涉及一种核级锆板或锆管专用的连续热处理炉。
背景技术
众所周知，锆板和锆管是用于核电站的核心部件，因此，性能要求非常苛刻。
目前，在锆板或锆管所采用的热处理炉，基本上包括炉体、位于炉体内的用于传输锆板或锆管移动的炉辊组件、以及加热组件，其中炉体内部区域自炉体的进口向出口依次分布的进料区、加热区、及出料区，而且炉辊组件的所有炉辊同步转动，且在各个温区的转动速度都一样。
然而，为了满足锆板或锆管热处理要求，一般所采用的炉体加热区需要很长，这样势必造成炉体较长且占用面积很大，同时热处理炉的结构更复杂，且使用成本较高。
发明内容
本发明所要解决的技术问题是克服现有技术的不足，提供一种改进的核级锆板或锆管专用的连续热处理炉。
为解决以上技术问题，本发明采取如下技术方案：
一种核级锆板或锆管专用的连续热处理炉，其包括炉体、设置在炉体内的炉辊组件，其中炉体包括自炉体的进口向出口依次设置的进料区、加热区、出料区，炉辊组件包括分别对应设置在进料区、加热区、及出料区内的第一炉辊组、第二炉辊组和第三炉辊组；分别驱动第一炉辊组、第二炉辊组和第三炉辊组以传送锆板或锆管在炉体内移动的第一驱动件、第二驱动件和第三驱动件；以及分别向第一驱动件、第二驱动件和第三驱动件下达运动指令以控制各个炉辊组传送速度和传递方向的PLC控制系统，其中当锆板或锆管位于加热区时，第二驱动件驱动第二炉辊组传动锆板或锆管在加热区内进行来回移动，直接加热完成后第二炉辊组再将锆板或锆管传向第三炉辊组，并由第三炉辊组将加热完成锆板或锆管传出炉体。
优选地，PLC控制系统包括分别设置在进料区、加热区和出料区中用于监控锆板或锆管所处具体区间位置的监控单元；接收监控单元所反馈的信息向第一驱动件、第二驱动件和第三驱动件下达传送速度和传送方向指令的处理器。
优选地，监控单元包括分别对应设置在进料区、加热区和出料区的区间界点处的多个传感器。
根据本发明的一个具体实施和优选方面，传感器有六个，其中每两个传感器之间分别对应进料区、加热区和出料区，且位于每相邻两个温区的之间两个传感器之间隔开设置。当然，相邻两个温区也可以采用一个传感器，这样一来三个传感器也是可行的，但是，本申请这样设置的好处是，一旦位于相邻两个温区之间的一个传感器出现故障后，也不会造成驱动指令的混乱，确保锆板或锆管只能在加热区来回移动加热。
优选地，传感器并排设置在多根炉辊形成传送通道的相对侧边。
优选地，第一炉辊组、第二炉辊组、及第三炉辊组分别独立的传动。这样便于进出料、以及在加热区来回移动速度的掌握，更有利于物料的热处理。
具体的，当进料时，第一炉辊组和第二炉辊组传动度相等，第三炉辊组空转；当物料进入加热区后，由第二炉辊组改变传动方向，物料在加热区来回移动，第一炉辊组和第三炉辊组以相同的速度空转；当出料时，第二炉辊组和第三炉辊组传动度相等，第一炉辊组空转。这样一来，实现物料的快速进料和快速出料，而且当其中两组炉辊组处于运料状态时，另一组炉辊组依然处于空转状态，这样才能延长炉辊组在高温环境下使用寿命，降低变形概率。
因此，在三个炉辊组的传动下，实现核级锆板或锆管快速进出炉，在加热区慢速的来回摆动。
此外，加热区沿着自身长度方向划分为多个分区，监控单元还包括位于相邻分区的界点处的感应器，其中在多个感应器的监测下更准确的判断锆板或锆管的位置。因此，在多个感应器的辅助下，更能够准确地实现锆板或锆管在加热区平稳的来回移动。
优选地，第一炉辊组、第二炉辊组和第三炉辊组的结构相同，均包括多根并排且均匀间隔设置的炉辊。
进一步的，第一驱动件、第二驱动件和第三驱动件的结构相同，均包括驱动电机、用于将驱动电机与所对应位置的多根炉辊中全部或部分炉辊相传动连接的传动件。申请人在此解释一下部分炉辊传动连接，其可以选择相邻的几根炉辊，也可以选择相间隔的几根炉辊，但最终的结果是：必须保证锆板或锆管在加热区平稳的来回移动。
由于以上技术方案的实施，本发明与现有技术相比具有如下优点：
本发明通过锆板或锆管在热处理炉的加热区来回移动，从而能够缩短整个炉体的长度，简化热处理炉的结构，同时也降低了使用成本；然后在满足锆板或锆管传递的前提下，每个炉辊组的独立驱动，进而降低能耗。

如图1所示，本实施例涉及的核级锆板或锆管专用的连续热处理炉，其包括炉体1、设置在炉体1内的炉辊组件2。
炉体1包括自炉体1的进口向出口依次设置的进料区1a、加热区1b、出料区1c。
炉辊组件2包括分别对应设置在进料区1a、加热区1b、及出料区1c内的第一炉辊组2a、第二炉辊组2b和第三炉辊组2c；分别驱动第一炉辊组2a、第二炉辊组2b和第三炉辊组2c以传送锆板或锆管在炉体内移动的第一驱动件(图中未显示，但不难想到)、第二驱动件(图中未显示，但不难想到)和第三驱动件(图中未显示，但不难想到)；以及分别向第一驱动件、第二驱动件和第三驱动件下达运动指令以控制各个炉辊组传送速度和传递方向的PLC控制系统2d， 其中当锆板或锆管位于加热区时，第二驱动件驱动第二炉辊组2b传动锆板或锆管在加热区内进行来回移动，直接加热完成后第二炉辊组2b再将锆板或锆管传向第三炉辊组2c，并由第三炉辊组2c将加热完成锆板或锆管传出炉体1。
具体的，PLC控制系统2d包括分别设置在进料区1a、加热区1b和出料区1c中用于监控锆板或锆管所处具体区间位置的监控单元d1；接收监控单元d1所反馈的信息向第一驱动件、第二驱动件和第三驱动件下达传送速度和传送方向指令的处理器。
监控单元d1包括分别对应设置在进料区1a、加热区1b和出料区1c的区间界点处的多个传感器d10。
本例中，传感器d10有六个，其中每两个传感器d10之间分别对应进料区1a、加热区1b和出料区1c，且位于每相邻两个温区的之间两个传感器之间隔开设置。当然，相邻两个温区也可以采用一个传感器d1，这样一来四个传感器也是可行的，但是，本申请这样设置的好处是，一旦位于相邻两个温区之间的一个传感器出现故障后，也不会造成驱动指令的混乱，确保锆板或锆管只能在加热区来回移动加热。
传感器d10并排设置在多根炉辊形成传送通道的相对侧边。
本例中，第一炉辊组2a、第二炉辊组2b、及第三炉辊组2c分别独立的传动。这样便于进出料、以及在加热区来回移动速度的掌握，更有利于物料的热处理。
具体的，当进料时，第一炉辊组2a和第二炉辊组2b传动度相等，第三炉辊组2c空转；当物料进入加热区后，由第二炉辊组2b改变传动方向，物料在加热区来回移动，第一炉辊组2a和第三炉辊组2c以相同的速度空转；当出料时，第二炉辊组2b和第三炉辊组2c传动度相等，第一炉辊组2a空转。这样一来，实现物料的快速进料和快速出料，而且当其中两组炉辊组处于运料状态时，另一组炉辊组依然处于空转状态，这样才能延长炉辊组在高温环境下使用寿命，降低变形概率。
因此，在三个炉辊组的传动下，实现核级锆板或锆管快速进出炉，同时也使得核级锆板或锆管在加热区慢速的来回摆动。
此外，加热区1b沿着自身长度方向划分为两个分区b1，监控单元d1还包 括位于相邻分区的界点处的感应器d11，其中在感应器d11的监测下更准确的判断锆板或锆管的位置。因此，在感应器d11的辅助下，更能够准确地实现锆板或锆管在加热区平稳的来回移动。
本例中，两个分区b1的界点处设有两个感应器d11，该两个感应器d11分布在两个分区b1交界处炉辊的相对两侧。
然后，第一炉辊组1a、第二炉辊组1b和第三炉辊组1c的结构相同，均包括多根并排且均匀间隔设置的炉辊。
第一驱动件、第二驱动件和第三驱动件的结构相同，均包括驱动电机、用于将驱动电机与所对应位置的多根炉辊中全部或部分炉辊相传动连接的传动件。申请人在此解释一下部分炉辊传动连接，其可以选择相邻的几根炉辊，也可以选择相间隔的几根炉辊，但最终的结果是：必须保证锆板或锆管在加热区平稳的来回移动。
