【技术实现步骤摘要】
一种注液针组
本技术涉及化学设备领域,具体涉及一种注液针组。
技术介绍
反应器是一种实现反应过程的设备,在化学领域经常采用试管用作于少量试剂的反应容器。而单个的试管反应器不能够满足自动化批量生产的要求,且试管反应器进液口与出液口均在上端同一个开口,自动排液需伸入一根抽液管至试管底部,采用泵来抽取,此种排液方式造成排液不彻底且抽液管内液体对试管内反应造成污染。基于上述情况,现研究一种注液针组,用于解决现有反应器不能适应自动化多模式生产及自动排液不彻底问题。
技术实现思路
本技术的目的是解决上述的不足,提供一种注液针组。为实现上述目的,本技术的技术解决方案是:一种注液针组,包括内针管、横向针管、三通接头、加长套管,所述三通接头内设有上下贯通的上细下粗的台阶孔,所述三通接头侧面设有与内部台阶孔下部直径较大孔腔相连的横向孔,所述三通接头横向孔连接有横向针管;所述内针管通过台阶孔内穿过三通接头并与台阶孔的上部直径较小的孔形成密封;所述加长套管内孔直径大于内针管的管体外径,所述加长套管套在内针管外部且上端连接在三通接头台阶孔的下端;所述内针管下端设有向外的喇叭状翻边,所述加长套管的下端与喇叭状翻边之间留有缝隙。进一步的,所述内针管及横向针管与三通接头之间采用紧固螺纹拧紧固定。进一步的,所述内针管及横向针管采用可弯曲的塑料管制成,所述三通接头、加长套管采用不锈钢材料制成。本技术的设计一种注液针组,其内针管与横向针管集成在一根管体内安装在反应瓶塞上,节约反应瓶塞上的空间;所述内针管与横向针管所形成的注液通道互不相通,能够同时加注不同液体且不会造成相互污染堵塞,提高反应质量及针组使 ...
