Graphite surface layer anti-oxidation SiC uniform circulation coating equipment
The invention relates to the technical field of anti-oxidation graphite material coating processing machinery, in particular to graphite surface layer anti-oxidation SiC uniform circulation coating equipment which comprises a processing platform and a reaction kettle mounted on the processing platform, and a graphitization tank set, a coating platform and an air blowing mechanism are arranged in the reaction kettle. A proportioned Si and SiO2 powder mixture is contained in a containing cavity in the graphitization tank set, a plurality of air inlet channels communicated with the bottom of thecontaining cavity are formed in the periphery of the containing cavity, and a communicated exhaust pipeline is arranged on the upper portion of the containing cavity. Monomer silicon powder and silicon dioxide powder in the graphitization tank set react to form silicon oxide gas, the silicon oxide gas is conveyed to the coating platform through the air blowing mechanism to coat a graphite workpiece on the platform, a silicon carbide coating is formed, gas in the reaction kettle circularly flows in the whole reaction process, and the silicon carbide coating is formed. The technical problem thatan existing graphite workpiece is uneven in coating is solved.
本发明涉及抗氧化石墨材料涂层加工机械技术领域，具体为一种石墨表层抗氧化SiC均匀循环涂层设备，包括加工平台，安装于加工平台上的反应釜，反应釜内设置有石墨化罐组、涂层平台及鼓风机构，其中，石墨化罐组内部的容腔内盛装有配比好的Si与SiO2的粉末混合物，容腔的四周设置有若干连通容腔底部的进气通道，容腔的上部设置有连通的排气管道；通过利用石墨化罐组内的单质硅粉末与二氧化硅粉末通过反应形成氧化硅气体，并利用鼓风机构将氧化硅气体输送至涂层平台对平台上的石墨工件进行涂层，形成碳化硅涂层，整个反应过程中，反应釜内气体形成循环流动，解决了现有石墨工件涂层不均匀的技术问题。
