Description

TECHNICAL FIELD

[0001] The present application relates to a multifunctional inorganic sample processing workstation, and belongs to the technical field of environmental sample detection instruments. BACKGROUND

[0002] When determining inorganic elements of environmental samples such as water samples, soil samples, solid waste and particulate matter trapped during atmospheric sampling, the environmental samples need to be digested. The role of digestion is to destroy organic matter, dissolve particulate matter, and oxidize various valence state elements to be measured into single high valence state or convert them into inorganic compounds that are easy to decompose. After digestion, the acidity of the sample needs to be reduced through acid chasing to avoid the uncertainty of the subsequent sample analysis process caused by the acidity, so digestion and acid chasing are essential basic steps in sample analysis and are also the pretreatment process of sample analysis, which has an important influence on the results of sample analysis.

[0003] In the current digestion and acid chasing process, the sample placed on the digestion tank is added with acid liquid by a digestion instrument, and then digestion is performed. Acid gas is generated during the digestion process. On the one hand, the acid gas directly volatilizes into the air, has strong corrosion, pollutes the air and the laboratory environment, and threatens the health of the experimenters for a long time. On the other hand, due to the temperature difference, the acid gas is easily condensed into acid liquid on the inner wall of the digestion tank and flows back to the sample, which affects the analysis results of the sample. At present, there is no very effective acid chasing method. SUMMARY

[0056] The workflow of the embodiment is as follows: a. Press the corresponding button of the electric control system 6 to return each component to the initial position, return the extraction system 4 to the upper end of the module system 3, then place the digestion instrument 11 in the middle of the base system 2, then slide the locking devices 24 at both ends along the U-shaped groove 232 to the sidewalls of the digestion instrument 11, rotate the second locking pressure rod 247 to fix the locking devices 24 on the base working platform 23, then press the first locking pressure rod 245 to press the locking pressure pad 244 against the digestion instrument 11, so that the digestion instrument 11 is fixed on the base working platform 23, then pour different kinds of pickling filtrate into the plurality of filter bottles 53, connect the gas outlet pipe 57 with the external air extractor, then check the connection of the corresponding gas pipes of the digestion instrument to ensure the sealing of the whole system; b. Then place the sample to be detected on the digestion tank 12, pour acid solution into the digestion tank 12, and place the digestion tank 12 in the corresponding digestion hole 111 of the digestion instrument 11; c. Press the corresponding button of the electric control system 6 to start, and the external air extractor works according to the program setting logic to continuously extract the gas in the gas outlet pipe 57, the module motor 36 on the module 34 moves to drive the module sliding block 35 to quickly descend, so that the extraction system 4 quickly moves downward, and the extraction device 42 extends into the inner hole of the digestion tank 12 until it is above the liquid level of the acid solution in the digestion tank 12. The digestion instrument 11 generates heat during work to raise the temperature of the digestion tank 12, and the acid solution in the digestion tank 12 digests the sample to be detected after heating, and the acid solution generates acid gas after heating; d. The extraction force generated by the external air extractor causes the extraction device 42 to continuously extract the high-temperature acid gas in the digestion tank 12, and the taper of the extraction cone portion 4212 causes the acid gas generated after the acid solution volatilizes to gather as much as possible in the inner hole of the rod body 4211. The acid gas is extracted upward to the extraction gas pipe 424, and the acid gas generated by the plurality of extraction devices 42 enters the first gas gathering device 43 through the gas pipe. Since the temperature of the first gas gathering device 43 is room temperature, part of the acid gas is liquefied into acid solution, flows to the middle hole of the tank body outer shell 4311 through the tank body slope 4314, then flows away along the first gas gathering adapter 434, enters the first gas gathering gas pipe 436, and the acid gas that is not liquefied is extracted into the first gas gathering adapter 434 under the action of the extraction force of the external air extractor, and then enters the first gas gathering gas pipe 436; e. Since the installation height of the second gas gathering device 45 is lower than that of the first gas gathering device 43, the acid gas and acid solution flowing out of the plurality of first gas gathering devices 43 can smoothly flow into the second gas gathering device 45 to form a gathering form. In the second gas gathering device 45, more acid gas is liquefied, and part of the acid gas is in a gaseous state, then flows into the filter bottle 53 through the second gas gathering gas pipe 455.f. After the acidic gas and acid liquid flow from the second gas-gathering device 45 to the filter bottle 53, multiple filter bottles 53 filter the acidic gas and acid liquid. On the one hand, the acidic gas is liquefied, and on the other hand, the acid liquid and the filtered liquid in the filter bottle undergo a chemical reaction to reach a neutral state, ensuring that the gas drawn from the gas outlet pipe 57 is neutralized gas and will not pollute the environment. g. As the acid liquid in the digestion tank 12 continues to evaporate, the liquid level of the acid liquid in the digestion tank 12 continues to decrease. At this time, the module motor 36 on the module 34 moves, driving the module slider 35 to slowly descend. This causes the extraction device 42 to descend along with the acid liquid level, ensuring that the acid gas generated in the digestion vessel 12 can be extracted in a timely manner. This ensures that the acid gas generated in the digestion vessel 12 is removed before liquefaction, guaranteeing the purity of the acid liquid in the digestion vessel 12 and ensuring the reliability of the sample digestion. After digestion by the digester 11, the module motor 36 on the module 34 moves, driving the module slider 35 to rise rapidly, causing the extraction device 42 on the extraction system 4 to leave the digester 11 and return to its initial position, completing the entire process of the multifunctional inorganic sample processing workstation.

[0057] Specific implementation method two: such as Figure 27 As shown, the difference between this specific embodiment and specific embodiment one is that the digester 11 is a cuboid structure design, while the other structural principles and connection relationships are the same as in specific embodiment one.
