在原子荧光仪测试过程中，需要大量的稀盐酸溶液作为载液。现有技术中，是利用供液蠕动泵，通过泵管将稀盐酸溶液导入载液槽，再经过进样针的吸取，通过进样管进入原子荧光仪中。上述载液的供液蠕动泵同时用于还原剂供液，在仪器运行时，供液蠕动泵的泵速主要由还原剂供液速度决定，这就导致了载液供液过快，大量载液被迫溢流排出，形成载液浪费。载液浪费是原子荧光分析中的一个重要问题。配置载液所需的优级纯浓盐酸属于管制酸，大量浪费不仅容易污染环境，也不利采购。In the test process of the atomic fluorescence spectrometer, a large amount of dilute hydrochloric acid solution is required as the carrier liquid. In the prior art, the liquid supply peristaltic pump is used to introduce the dilute hydrochloric acid solution into the liquid-carrying tank through the pump tube, and then through the suction of the sampling needle, it enters the atomic fluorescence instrument through the sampling tube. The liquid supply peristaltic pump for the carrier liquid is also used for the reducing agent liquid supply. When the instrument is running, the pumping speed of the liquid supply peristaltic pump is mainly determined by the reducing agent liquid supply speed. The liquid is forced to overflow and discharge, forming a waste of carrier liquid. Carrier waste is an important issue in atomic fluorescence analysis. The high-grade pure concentrated hydrochloric acid required to configure the carrier liquid is a controlled acid, and a large amount of waste not only easily pollutes the environment, but also is not conducive to procurement.

下面是依据本实用新型的一个实施例。Below is an embodiment according to the utility model.
如图1、图2所示，本实用新型所述的自动补液装置包括：供液槽1、供液管阀门2、供液管3、载液槽4、漂浮球5、连接杆6、补液活塞7、进样针8、进样管9、排液管阀门10、排液管11。供液槽1内装有用做载液的溶液，供液槽1通过供液管3与载液槽4底部的补液孔12相连，补液活塞7控制补液孔12的开启和关闭，供液管3上设置有供液管阀门2，载液槽4内设置有可漂浮于载液液面上的漂浮球5，漂浮球5通过连接杆6与补液活塞7相连。As shown in Figure 1 and Figure 2, the automatic liquid replenishment device described in the utility model includes: liquid supply tank 1, liquid supply pipe valve 2, liquid supply pipe 3, liquid carrying tank 4, floating ball 5, connecting rod 6, liquid replenishment Piston 7, sampling needle 8, sampling tube 9, drain tube valve 10, drain tube 11. The liquid supply tank 1 is equipped with a solution used as a carrier liquid. The liquid supply tank 1 is connected to the liquid replenishment hole 12 at the bottom of the liquid carrier tank 4 through the liquid supply pipe 3. The liquid replenishment piston 7 controls the opening and closing of the liquid replenishment hole 12. The upper liquid supply pipe 3 A liquid supply pipe valve 2 is provided, and a floating ball 5 that can float on the surface of the liquid carrier liquid is provided in the carrier liquid tank 4 , and the floating ball 5 is connected with the liquid replenishment piston 7 through a connecting rod 6 .
当漂浮球5随着载液液面上升时，带动连接杆转动，使补液活塞7向下移动直至将补液孔12关闭，当漂浮球5随着载液液面下降时，带动连接杆转动，使补液活塞7向上移动从而将补液孔12打开。When the floating ball 5 rises with the carrier liquid level, it drives the connecting rod to rotate, so that the liquid replenishment piston 7 moves downward until the liquid replenishment hole 12 is closed. When the floating ball 5 descends with the carrier liquid level, it drives the connecting rod to rotate, The liquid replenishment piston 7 is moved upward to open the liquid replenishment hole 12 .
进样针8从载液槽4的上方插入载液槽4，进样针8的针头在载液液面以下时，可以将载液吸入进样管9，然后进入分析仪器进行检测。所述分析仪器可以是需要载液的各种分析仪器，例如原子荧光仪等。The sampling needle 8 is inserted into the carrier liquid tank 4 from the top of the carrier liquid tank 4. When the needle of the sampling needle 8 is below the carrier liquid level, the carrier liquid can be sucked into the sampling tube 9, and then enters the analysis instrument for detection. The analytical instrument can be various analytical instruments that require a carrier liquid, such as an atomic fluorescence instrument and the like.
载液槽4的底部设置有排液管11，用于将载液槽4内的残余载液排出，排液管11与载液槽4的底部的排液孔13相连，排液管11上设置有排液管阀门10。The bottom of the liquid carrier tank 4 is provided with a liquid discharge pipe 11, which is used to discharge the residual carrier liquid in the liquid carrier tank 4.

在一个实施例中，所述自动补液系统用于原子荧光仪分析中的载液补给。当原子荧光仪进行测试样品的工作时，关闭排液管阀门10并开启供液管阀门2。载液从供液槽1依靠重力通过供液管3流入载液槽4进行自动补液，进样针8吸取载液槽中的载液通过进样管9进入原子荧光仪。当载液补给过多时，浮力使漂浮球5上升，漂浮球带动连接杆6转动，使补液活塞7关闭补液孔12，补液过程自动停止。当载液不足时，漂浮球5受重力作用下降，带动连接杆6转动，使补液活塞7打开补液孔12，补液自动进行。In one embodiment, the automatic liquid replenishment system is used for carrier liquid replenishment in atomic fluorescence analysis. When the atomic fluorescence instrument is working to test the sample, close the valve 10 of the liquid discharge pipe and open the valve 2 of the liquid supply pipe. The carrier liquid flows from the liquid supply tank 1 to the carrier liquid tank 4 by gravity through the liquid supply pipe 3 for automatic liquid replenishment, and the injection needle 8 absorbs the carrier liquid in the liquid carrier tank and enters the atomic fluorescence instrument through the sampling tube 9 . When the carrier liquid is supplied too much, the buoyancy will cause the floating ball 5 to rise, and the floating ball will drive the connecting rod 6 to rotate, so that the liquid replenishing piston 7 will close the liquid replenishing hole 12, and the liquid replenishing process will stop automatically. When the carrier liquid is insufficient, the floating ball 5 descends under the action of gravity, which drives the connecting rod 6 to rotate, so that the liquid replenishment piston 7 opens the liquid replenishment hole 12, and the liquid replenishment is carried out automatically.
当原子荧光仪停止工作后需要清洗载液槽4时，关闭供液管阀门2并开启排液管阀门10。载液槽中残余载液从排液管11排出，载液排净后可用去离子水或蒸馏水清洗载液槽4。When the liquid carrier tank 4 needs to be cleaned after the atomic fluorescence instrument stops working, the liquid supply pipe valve 2 is closed and the liquid discharge pipe valve 10 is opened. The residual carrier liquid in the carrier liquid tank is discharged from the liquid discharge pipe 11, and the carrier liquid tank 4 can be cleaned with deionized water or distilled water after the carrier liquid is drained.
