The utility model relates to a closed type dosing device, which is provided with a diaphragm type dosing pump and a closed type medicine adding tank on the steel mounting base, and a filter is arranged on the pipeline between the dosing pump and the dosing tank. Dosing tank made sealed with a dosing tank, the inlet and outlet and connected to the atmosphere outside of the dosing room left in the top closed dosing tank, pump barrel into the medicine outlet and the medicine adding chamber connection, a water inlet; the bottom there is a connection with the dosing pump outlet is convenient; to observe the change of liquid level on the side of the dosing tank and a liquid level gauge is installed. The inlet and outlet of the pipeline and the medicine adding chamber is connected with the air, which is not affected by the volatile medicament in the pollution; end torque and power end of diaphragm metering pump dosing by diaphragm isolation, dosing pump is in normal working without leakage, ensure the dosing chamber can not harm caused by the leakage of pollution by drug agents the. The utility model has the advantages of good sealing effect and no leakage, and the indoor air quality of the dosing room has been remarkably improved, and the effect is obvious.
【技术实现步骤摘要】
本技术属于石油化工领域的加药装置,特别是一种密闭式加药装置。
技术介绍
目前加药装置的加药罐一般由敞口的加药罐和柱塞式计量加药泵组成。敞口的加药罐会挥发部分药剂到加药间的空气中,柱塞式计量加药泵一般会有或多或少的泄露;挥发和泄露的化学药剂会对加药间室内的环境造成污染,影响操作人员的身体健康。
技术实现思路
为了克服现有的加药装置挥发和泄露药剂对加药间室内的环境造成污染,影响操作人员身体健康的不足,本技术提供一种密闭式加药装置,使加药间内的药剂与室内空气完全隔离,达到减少室内空气污染改善室内工作环境的目的。本技术解决其技术问题所采用的技术方案是在钢制安装底座上安装有隔膜式计量加药泵和密闭式加药罐,隔膜式计量加药泵和密闭式加药罐的出液口间由加药泵进口管线连接,加药泵进口管线上有过滤器。加药罐制作成密闭式加药罐,在密闭式加药罐的顶部留有一个进排气口、底部有一个加药泵连接的加药罐出液口,以及一个进药口和一个进水口;进排气口通过管线与加药间室外大气连通,密闭式加药罐的呼吸空气中的有毒有害物质直接排到室外,保证了加药间内不受挥发药剂的污染;底部的加药罐出液口通过过滤器和管线与隔膜式计量加药泵连接,由于隔膜式计量加药泵的液力端和动力短由隔膜隔离的,在加药泵正常工作时是无泄漏的,保证了加药间内不受药剂泄漏造成污染的危害。本技术的有益效果是密闭效果好,无泄漏,加药间室内空气质量得到了显著改善,效果非常明显。附图说明结合附图和实施例,对对本技术进一步说明。图1是密闭式加药装置的结构原理图;图2是密闭式加药装置的一个实施例。图中(1)、(28)钢制安装底座;(2)、(15)加药泵 ...
