Description

Technical Field

[0001] This utility model relates to the field of chemical analysis and detection technology, and in particular to an automatic titration analysis device for chemical analysis and detection. Background Technology

[0002] In addition to performing potentiometric titrations, including acid-base titrations, redox titrations, precipitation titrations, complexometric titrations, and non-aqueous titrations, automatic potentiometric titrators can also perform constant pH measurements. With optional accessories, they can perform photometric titrations, polarimetric titrations, volumetric Karl Fischer titrations of moisture, and surfactant titrations, among other titration analysis methods. When used in conjunction with a fully automated multi-sample converter, the automatic titrator not only efficiently enables automated measurement of large numbers of samples but also improves the repeatability and reliability of the analysis, while remaining simple to operate and saving time and effort. In practical chemical experiments, solutions are often added dropwise to test tubes for observation and analysis of chemical reactions. During these experiments, it is crucial to ensure accuracy and safety. Current fully automated titration analyzers lack auxiliary protective measures during dropwise addition, making spillage and other dangerous situations prone to occur. Furthermore, the test tubes are difficult to clean after use, easily retaining solvent droplets, which hinders the reuse of the analyzer. Therefore, we propose an automatic titration analyzer for chemical analysis and detection. Utility Model Content

This invention solves the problems of current fully automatic titration analyzers, which are inconvenient for auxiliary protective titration, prone to spillage and other dangerous situations, and difficult to clean after use, easily leaving solvent droplets and hindering the reuse of the analyzer.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0022] like Figure 1-3 As shown, this utility model is an automatic titration analysis device for chemical analysis and detection, including a housing 1. A support base 2 is provided in the middle of the housing 1, and the support base 2 can move horizontally on the housing 1. By adjusting the position of the support base 2, the detection tube 4 and reagent tube 8 are easier to place and remove. A detection component 3 is provided on one side of the upper end of the housing 1. The detection component 3 can be externally connected to a potentiometer, which can be used to analyze the titrant. A detection tube 4 is provided below the detection component 3, and the detection tube 4 is threadedly connected to the lower end of the detection component 3, thus making the detection tube 4 easier to place and remove. The support base 2 has a clearance groove 5 that matches the detection tube 4. Multiple equidistant placement slots 7 are provided on the side of the support base 2 away from the clearance groove 5. The reagent tube 8 is placed in the placement slot 7. The reagent tube 8 can be placed inside the placement slot 7. A sealing cap 9 is provided above the reagent tube 8. The sealing cap 9 is threadedly connected to the reagent tube 8. The opening and closing of the sealing cap 9 makes it easier for the reagent to enter the reagent tube 8. A pump body 10 matching the reagent tube 8 is provided at the upper end of the housing 1. A through hole 12 is provided in the middle of the sealing cap 9. The input end of the pump body 10 extends to the bottom of the reagent tube 8 through the through hole 12 via the first conduit 11. The output end of the pump body 10 extends to the bottom of the detection component 3 via the second conduit 13. A detection probe 6 is provided on the side of the detection component 3 away from the second conduit 13. When the pump body 10 is working, the pump body 10 extracts the reagent inside the reagent tube 8 through the first conduit 11. After the reagent is extracted, it is transmitted through the second conduit 13 so that the reagent can enter the detection tube 4.

[0023] A control panel 14 is provided on the side of the housing 1 away from the detection component 3. The working status of the titration analysis device can be controlled through the control panel 14.

[0024] The outer side of the sealing cover 9 is provided with anti-slip texture 15, which effectively increases the friction between the sealing cover 9 and the fingers, making it easier to rotate the sealing cover 9.

[0025] The reagent tube 8 is provided with a first scale 16 on the outside, which makes it easier to observe the volume of the reagent inside the reagent tube 8.

[0026] The detection tube 4 is provided with a second scale 17 on the outside, which makes it easier to observe the volume of the reagent inside the detection tube 4.

[0027] The support base 2 is provided with sliders 18 on both sides below, and the housing 1 is provided with a groove 19 that matches the sliders 18. The sliders 18 can slide inside the groove 19. Through the cooperation between the sliders 18 and the groove 19, the movement stability of the support base 2 is effectively improved.

[0028] The support base 2 is provided with grooves 20 on both sides, which makes it easier for the support base 2 to be pushed and pulled.

[0029] Specifically, in this invention, during titration analysis, the sample solution is placed inside the detection tube 4, which is fixedly installed at the lower end of the detection assembly 3. The required titration reagent is poured into the reagent tube 8, which is then sealed and placed inside the placement groove 7. The first conduit 11 is inserted into the reagent tube 8 through the through hole 12. The support 2 moves into the housing 1. When the pump 10 is working, it extracts the reagent inside the reagent tube 8 through the first conduit 11. After the reagent is extracted, it is transmitted through the second conduit 13, allowing the reagent to enter the detection tube 4. The detection assembly 3 can detect the reagent inside the detection tube 4 through the detection probe 6. The titrated solution can be analyzed by connecting an external potentiometer. Both the detection tube 4 and the reagent tube 8 can be disassembled, making it easier for staff to clean the detection tube 4 and reagent tube 8 after use.
