Description

Technical Field

[0001] This utility model relates to the field of chemical testing of textiles, and more specifically, to a device for detecting the composition of azo dyes in textiles. Background Technology

[0002] Textiles are products made through processing and weaving. Although special processes enable textiles to retain excellent properties such as moisture absorption, antibacterial properties, and ease of dyeing, they also improve spinnability and wearing comfort. A search revealed an existing patent (publication number: CN222232337U) disclosing a device for detecting the composition of azo dyes in textiles, relating to the field of composition detection devices. The device includes a main body with a display screen on its top outer wall, a push-button switch on the side of the top outer wall away from the display screen, a partition on the inner wall, a cooling fan on the bottom inner wall, multiple sets of heat dissipation holes evenly distributed on the bottom outer wall, a spectrometer on the side of the bottom inner wall away from the cooling fan, two sets of elongated slide rails symmetrically distributed on the top inner wall, an infrared laser on the inner wall of each slide rail, and a glass layer on the top of the inner wall away from the infrared laser. This invention improves the safety performance of the device and makes it easier for users to operate.

[0003] In existing sample tubes, the solvent flow in the central region is obstructed after the sample accumulates, which easily forms an extraction blind zone, resulting in insufficient dye extraction from the central sample. At the same time, the aforementioned cited patent documents do not propose any solutions to address the above problems. Therefore, a device for detecting the composition of azo dyes in textiles is proposed to address the above-mentioned problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] As attached Figures 1 to 4 The device for detecting azo dye components in textiles shown includes a main housing 1, a sample tube 4 disposed inside the main housing 1, the sample tube 4 being tapered, and a circulation conduit 5 being connected through one side of the sample tube 4, the circulation conduit 5 extending to the upper and lower side walls of the sample tube 4.

[0020] Specifically, the sample tube 4 is designed in a conical shape to guide the condensed solvent to flow along the wall towards the center, achieving complete coverage of the sample with steam fumigation. Meanwhile, one end of the circulation conduit 5 extends to the upper side wall of the sample tube 4 to collect the evaporated solvent vapor inside the sample tube 4 and guide it to the condensation area; the other end extends to the lower side wall of the sample tube 4 to return the condensed liquid solvent to the sample tube 4, enabling solvent reuse. Example

[0021] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, a support mesh 6 is provided at the bottom of the sample tube 4, and a heating element 7 is provided inside the support mesh 6. The heating element 7 is made of graphene material. Furthermore, by providing the heating element 7, the solvent inside the sample tube 4 is heated, causing the solvent to evaporate and form vapor.

[0022] In a preferred embodiment, a connecting tube 8 is provided on one side of the sample tube 4, a peristaltic pump 9 is provided on one side of the connecting tube 8, and a filter 10 is provided on one side of the peristaltic pump 9; furthermore, by providing the filter 10, impurities such as residual textile fiber fragments in the extract can be filtered out, preventing impurities from entering the subsequent micro liquid chromatography column 12.

[0023] In a preferred embodiment, a quantitative injection valve 11 is provided at one end of the connecting tube 8, and a micro liquid chromatography column 12 is fixedly provided at the other end of the quantitative injection valve 11. Furthermore, by providing a micro liquid chromatography column 12, the chromatographic packing material filled inside can utilize the differences in adsorption force and solubility between different azo dyes and the packing material to make multiple azo dyes in the extract move along the chromatographic column at different speeds.

[0024] In a preferred embodiment, an ultraviolet detector 13 is fixedly disposed on one side of the micro liquid chromatography column 12, and a mounting base 14 is disposed on both sides of one end of the ultraviolet detector 13; furthermore, by disposing of the ultraviolet detector 13, changes in light signal intensity are converted into electrical signals by emitting ultraviolet light of a specific wavelength.

[0025] In a preferred embodiment, a micro motor 15 is provided on one side of the fixed base 14, and a lead screw 16 is connected to one side of the micro motor 15 via an output shaft. A slider 17 is externally threaded to the lead screw 16, and an infrared laser calibrator 18 is provided at the front end of the slider 17. A guide rod 19 is provided on one side of the slider 17. Furthermore, by providing the infrared laser calibrator 18, infrared lasers are emitted during the movement of the slider 17 to detect and correct the ultraviolet light emission path and receiving path of the ultraviolet detector 13, thereby avoiding detection signal distortion caused by optical path offset.

[0026] In a preferred embodiment, a sample inlet 2 is provided on one side of the upper end of the main housing 1 via a hinge, and a display screen 3 is provided on one side of the sample inlet 2; furthermore, by providing a display screen 3, it is convenient for operators to preset detection parameters such as extraction temperature and sample injection volume.

[0027] The working process of this utility model is as follows: First, open the sample inlet 2, which is hinged at the top of the main housing 1. Place the textile sample, cut to a suitable particle size, into the internal conical sample tube 4. The sample is laid flat on the support mesh 6 at the bottom of the sample tube 4. Close the sample inlet 2 to ensure the device is sealed and prevent solvent evaporation or vapor leakage during subsequent extraction. The graphene heating element 7 inside the support mesh 6 at the bottom of the sample tube 4 is activated. The heat released by the heating element 7 is transferred to the extraction solvent in the sample tube 4. The solvent evaporates upon heating, forming solvent vapor. The solvent vapor flows along the circulation conduit 5 that runs through and connects to the sample tube 4. When the vapor rises to the top of the circulation conduit 5, it exchanges heat with the low-temperature environment inside the device and condenses into liquid solvent. The condensed liquid solvent flows along the circulation conduit 5. The solvent flows downwards along the inner wall of the ring tube 5 and eventually exits from the tube port extending to the lower side wall of the sample tube 4. Because the sample tube 4 is conical, the solvent drips evenly along the conical wall onto the sample surface, dissolving the azo dye on the sample surface. Simultaneously, a small amount of uncondensed solvent vapor diffuses upwards from the perforation at the bottom of the cone of the sample tube 4, fumigates the deeper layers of the sample, and the extract containing the dissolved azo dye passes through the support mesh 6 under gravity, collecting at the bottom of the sample tube 4. Additionally, the peristaltic pump 9 on one side of the connecting tube 8 pumps the collected extract into the filter 10. The filter 10 removes impurities such as textile fiber debris from the extract, preventing clogging of subsequent detection components and ensuring sample purity. The filtered, clarified extract continues to be delivered to the quantitative injection valve 11 through the connecting tube 8. The quantitative injection valve 11 injects a preset amount to avoid deviations in detection results due to variations in injection volume. The quantified extract is then fed into a micro-liquid chromatography column 12 fixed at one end of the quantitative injection valve 11. When the extract flows within the micro-liquid chromatography column 12, it moves along the column at different speeds and eventually flows out of the column outlet in sequence, achieving the separation of different azo dye components. When the separated single azo dye component flows into the UV detector 13 fixed on one side of the micro-liquid chromatography column 12, the UV light emitted by the UV detector 13 passes through the dye solution, and some of the light is absorbed by the azo groups. The electrical signal intensity is positively correlated with the concentration of the azo dye, thereby achieving quantitative analysis of the dye. Finally, during the UV detection process, the micro motor 15 on the fixed base 14 is started, driving the lead screw 16 to rotate through the output shaft. The slider 17, connected to the external thread of the lead screw 16, moves smoothly along the axial direction of the lead screw 16 under the limiting action of the guide rod 19. The infrared laser calibrator 18 at the front end of the slider 17 moves with the slider 17 and emits infrared laser to the optical path system of the ultraviolet detector 13 to avoid detection errors caused by optical path deviation. The ultraviolet detector 13 calculates the type and content of azo dye by combining the peak time and peak area of ​​chromatographic separation. The final detection result is displayed intuitively on the display screen 3 on the main housing 1, completing the entire detection process.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
