Preparation method and preparation equipment of nuclear-grade graphite
The invention relates to a preparation method of nuclear-grade graphite. The preparation method comprises the following steps: S1, mixing and kneading, S2, crushing, S3, isostatic pressing, S4, roasting, S5, dipping, S6, graphitizing and S7, purifying. Nuclear-grade graphite preparation equipment comprises a roasting furnace and a purification furnace, the roasting furnace comprises a sealed graphitization cavity, the front end and the rear end of the graphitization cavity are provided with a sealed feeding cavity and a sealed discharging cavity respectively, and the end of the feeding cavity and the end of the discharging cavity are each provided with an openable end sealing door; openable middle sealing doors are arranged between the graphitization cavity and the feeding cavity and between the graphitization cavity and the discharging cavity, backflow assemblies are arranged between the feeding cavity and the graphitization cavity and between the discharging cavity and the graphitization cavity, and each backflow assembly comprises a backflow pipe and a first sucking pump. The invention aims to solve or at least alleviate the defects in the prior art, and provides the nuclear-grade graphite preparation method and preparation equipment, purification is carried out in the graphite roasting and purification process, and the method is simple and easy to operate, and is very suitable for large-scale production.
本发明涉及一种核级石墨制备方法，制备方法包括以下步骤：S1、混捏，S2、粉碎，S3、等静压成型，S4、焙烧，S5、浸渍，S6、石墨化，S7、纯化。一种核级石墨制备设备，核级石墨制备设备包括焙烧炉和纯化炉，焙烧炉包括密封的石墨化腔，石墨化腔前后两端分别设置有密封的进料腔和出料腔，进料腔和出料腔端部均设置有可开启的端密封门，石墨化腔与进料腔和出料腔之间均设置有可开启的中密封门，进料腔和出料腔与石墨化腔之间均设置有回流组件，回流组件包括回流管和第一抽气泵。本发明的目的在于解决或至少减轻现有技术存在之缺失，提供一种核级石墨制备方法及制备设备，在石墨焙烧及纯化的过程中进行纯化，该方法简单易操作，非常适合大规模生产。
