一种稀土熔盐电解炉
本技术涉及稀土生产设备领域,尤其涉及一种稀土熔盐电解炉。
技术介绍
电解是电流通过物质而引起化学变化的过程,化学变化是物质失去或获得电子的过程,电解过程是在电解池中进行的,电解池是由分别浸没在含有正、负离子的溶液中的阴、阳两个电极构成,电流流进负电极,溶液中带正电荷的正离子迁移到阴极,并与电子结合,变成中性的元素或分子;带负电荷的负离子迁移到另一电极,给出电子,变成中性元素或分子。目前,国内所采用的稀土金属生产以熔盐电解技术为主,但是通过电解方法析出的金属容易附着在极板的表面,需要定期取出极板进行清除,影响工作效率。本技术即是针对现有技术的不足而研究提出的。
技术实现思路
本技术的目的是克服上述现有技术的缺点,提供了一种自动清除附着在阴极金属表面金属的一种稀土熔盐电解炉。本技术可以通过以下技术方案来实现:本技术公开了一种稀土熔盐电解炉,包括炉体,所述炉体内部设有阳极柱和阴极柱,所述阳极柱外周侧固定有集气罩,所述集气罩上连接有穿过集气罩的集气管,所述集气罩内壁上设有排气孔,所述排气孔与集气罩上方的保护气管相连接,所述阴极柱外周侧设有内壁与阴极柱外壁配合的刮板,所述刮板上方固定连接有多个伸缩杆,所述炉体内部还设有抽液管,所述抽液管与抽液泵相连,所述抽液管的入口位于炉体内底部。通过保护气管往集气罩内排入惰性气体,降低了阳极柱表面的氧气浓度,降低了阳极柱的氧化速度,延长了电解炉的使用寿命,通过在阴极柱表面设置刮板,电解一段时间后,启动伸缩杆,推动 ...
