Problems solved by technology

In addition, in the acid removal process, the end point of acid removal needs to be judged by human eyes, and acid mist is generated, which not only consumes manpower, but also causes certain damage to the laboratory technician's body.
[0003] The measurement process of the existing digestion and acid removal equipment is cumbersome and time-consuming, requiring the experimenter to add samples to the digestion bottle one by one, and due to the uncertainty of the operation of the experimenter, the number of samples added varies, which has a negative impact on the measurement results. certain impact, the accuracy of test results is not high
Moreover, during the test process, as the heating proceeds, the acid gas in the digestion bottle will evaporate into the air and be discharged into the atmosphere without treatment, causing strong acid pollution, which does not meet the national environmental protection standards

Embodiment 1

[0030] Embodiment one: if figure 1 , figure 2 , image 3 As shown, the invention includes a heating temperature control device and an acid gas treatment device. The heating temperature control device includes a heating device for heating the digestion bottle 15 and a temperature control device for temperature control of the heating device, that is, a temperature controller 14. The temperature of the heating device can be adjusted according to the specific conditions of the experiment. A plurality of digestion bottle installation cavities 2 are arranged on the square heating plate 1 of the heating device, and the bottom of the digestion bottle is vertically placed in the digestion bottle installation cavities. Moreover, the installation cavities of the digestion bottles are evenly arranged in rows and columns on the heating plate.

[0031] The acid gas treatment device is mainly a treatment pool filled with lye.

[0032] The invention also includes an automatic liquid addi...

Embodiment 2

[0045] Embodiment two: if Figure 7 As shown, for the automatic liquid adding device in Embodiment 1, the automatic liquid adding device in this embodiment includes a mechanical arm, and one end of the mechanical arm cooperates with the horizontal slide rail 13 of the acid removal instrument, and can move along the horizontal slide rail . The other end of the mechanical arm is a free end, and a concentrated acid input pipe is provided in the mechanical arm. The input end of the concentrated acid input pipe is connected with multiple concentrated acid bottles at the same time, and the concentrated acid in each concentrated acid bottle is different. A control valve is provided at the connection between the input end of the input pipe and each concentrated acid bottle. Realize that different kinds of concentrated acids are automatically added to the digestion bottle through the input pipe and the liquid feeding pipe at the same time. The amount of concentrated acid added to the ...

Abstract

The invention relates to a digestion acid dispelling instrument which comprises a heating temperature control device and an acid gas treatment device, wherein a plurality of digestion bottles are arranged on a heating plate of the heating temperature control device; the digestion acid dispelling instrument is characterized by further comprising an automatic liquid adding device, an acid gas absorption device and an end point determination device; the digestion bottles are evenly arranged on the heating plate in multiple rows and lines; the acid gas absorption device is arranged above the heating device and is connected with the acid gas treatment device. After the digestion acid dispelling instrument is used, the concentrated acid is automatically added, the end point is automatically controlled, the acid dispelling accuracy and the constant volume accuracy of digestion-acid dispelling can be guaranteed, and the measurement result is repetitive and reliable. The volatile acid gas is treated in a neutralizing way after being collected in a centralized way, so that the pollution caused by the acid gas is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical experiment instruments, in particular to a digestion and acid removal instrument used in the process of sample determination. Background technique [0002] For the determination of metals in solid samples, digestion and acid removal are two essential basic steps. The steps of digestion and acid removal occupy more than 90% of the workload in the whole test process, and these two steps are the main links that affect the accuracy of the test results. In addition, during the acid removal process, the end point of the acid removal needs to be judged by human eyes, and acid mist is generated, which not only consumes manpower, but also causes certain damage to the laboratory technician's body. [0003] The measurement process of the existing digestion and acid removal equipment is cumbersome and time-consuming, requiring the experimenter to add samples to the digestion bottle one by one, and due to th...
