Description

Technical Field

[0001] This utility model relates to the field of extraction and detection technology, and in particular to a rapid extraction and detection device for anthraquinone derivatives. Background Technology

[0002] Anthraquinone derivatives play a crucial role in numerous industries, including pharmaceuticals, chemicals, and printing and dyeing. Currently, the extraction and detection of anthraquinone derivatives are typically accomplished using specialized equipment. This equipment generally includes extraction tanks, solvent addition components, and other extraction units. Through the synergistic action of these components, the target substance can be rapidly extracted from samples containing anthraquinone derivatives. The extract flows into a filtration device where it undergoes preliminary filtration to remove impurities before being placed into the detection unit. Advanced detection methods such as spectroscopic and chromatographic modules are used for qualitative and quantitative analysis of the anthraquinone derivatives. Finally, the data processing and display module presents the detection results. The entire process is integrated and automated by an intelligent control system. However, because the filter installation structure in many devices is complex (e.g., fixed with bolts), disassembling and cleaning the filter often requires specialized tools and involves significant time and effort. Reinstallation after cleaning is cumbersome and time-consuming, hindering the convenience and efficiency of filter assembly and disassembly. Utility Model Content

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a rapid extraction and detection device for anthraquinone derivatives, including a workbench 1, on which an extraction tank 23 and a detection box 3 are arranged. A discharge pipe 4 is fixedly connected to the bottom of the extraction tank 23, and a filter box 5 is fixedly connected to the bottom of the discharge pipe 4. A discharge pipe 12 is fixedly connected to the bottom of the filter box 5, and an electric control valve 21 is installed on the discharge pipe 4. Several slots 18 are opened on the surface of the filter box 5, and filter screen frames 8 with progressively smaller pore sizes are inserted into the slots 18 from top to bottom. The filter screen frames 8 are fixedly connected to the filter box 5 by a locking assembly 11. The locking assembly 11 includes a fixing block 111, which is fixedly connected to the side wall of the filter box 5. A screw 112 is threadedly connected to the inside of the fixing block 111, and a locking block 113 is rotatably connected to the surface of the screw 112. The locking block 113 and the filter screen frames 8 are located outside the slots 18. The edges abut against each other. A knob 114 is fixedly connected to the end of the screw 112 away from the fixing block 111. The top of the extraction tank 23 is provided with a feed pipe 10 and a solvent delivery pipe 9. A motor 13 is fixedly connected to the top of the extraction tank 23. The output end of the motor 13 passes through the top of the extraction tank 23 and is fixedly connected to a vertical rod 14. A stirring rod 15 is fixedly connected to the vertical rod 14. A shell 2 is fixedly connected to the outside of the extraction tank 23. A heating wire 19 is provided inside the shell 2. The heating wire 19 is wound around the outside of the extraction tank 23. An ultrasonic generator 20 is fixedly connected to the bottom of the extraction tank 23. A flow regulating valve 22 is provided near the extraction tank 23 in the solvent delivery pipe 9. The other end of the solvent delivery pipe 9 is fixedly connected to the solvent storage tank. A square groove 6 is provided on the side of the filter box 5 where the slot 18 is opened. The bottom of the square groove 6 is connected to the slot 18. A sealing gasket 7 is provided on the inner side of the square groove 6.

[0017] In this embodiment, the filter frame 8 is fixed by a locking assembly 11 consisting of a fixing block 111, a screw 112, a locking block 113, and a knob 114. This allows for easy disassembly and cleaning of the filter frame 8 without the need for complex professional tools. Simply rotating the knob 114 to rotate the screw 112 easily releases the locking block 113 from the filter frame 8. This convenient operation effectively improves the ease of filter assembly and disassembly, facilitating the cleaning of impurities inside the filter frame 8 and preventing clogging of the pores that could affect the filtration effect, thereby improving overall work efficiency. Furthermore, by installing a motor 13 at the top of the extraction tank 23, which drives the upright rod 14 and stirring rod 15 to rotate, the sample containing anthraquinone derivatives can be thoroughly mixed with the solvent, accelerating the dissolution of the anthraquinone derivatives into the solvent. Simultaneously, a winding mechanism is installed on the outside of the extraction tank 23... The heating wire 19 creates a suitable temperature environment, and the bottom is equipped with an ultrasonic generator 20, which uses ultrasonic cavitation to promote the release of anthraquinone derivatives. The synergistic effect of multiple methods significantly improves the rapid extraction efficiency of anthraquinone derivatives. By setting a flow regulating valve 22 near the extraction tank 23 on the solvent delivery pipe 9, the flow rate of the solvent entering the extraction tank 23 can be precisely adjusted according to the specific extraction requirements, ensuring the accuracy of the solvent dosage and avoiding the impact of too much or too little solvent on the extraction efficiency and effect of anthraquinone derivatives. By setting a sealing gasket 7 on the inside of the square groove 6, when the filter frame 8 is inserted into the groove opening 18 and related operations are performed, the sealing gasket 7 can effectively fill the gaps and prevent the extract from leaking from the groove opening 18 during the filtration process. This ensures the normal operation of the filtration process and avoids environmental pollution and damage to other components of the device caused by leakage.

[0018] Example 2: As Figure 2 - Figure 4 As shown, a connecting rod 16 is fixedly connected to the upright 14, and a scraper 17 is fixedly connected to the end of the connecting rod 16 away from the upright 14. The blade of the scraper 17 abuts against the inner wall of the extraction tank 23. A limiting rod 24 is fixedly connected to the locking block 113. A limiting groove 25 is opened on the filter screen frame 8 at the position corresponding to the limiting rod 24, and the limiting rod 24 is inserted into the limiting groove 25.

[0019] In this embodiment, the connecting rod 16 and scraper 17 are connected to the upright rod 14, and the blade of the scraper 17 abuts against the inner wall of the extraction tank 23. While the stirring rod 15 is stirring, the scraper 17 can rotate together to scrape off the material attached to the inner wall of the extraction tank 23 in time, avoiding the accumulation of material residue that will affect subsequent extraction. It also facilitates subsequent cleaning and maintenance of the extraction tank 23, ensuring a clean and tidy internal environment, which is conducive to continuous and stable extraction. By inserting the limiting rod 24 on the locking block 113 into the limiting groove 25, the locking block 113 can be kept stable when the filter frame 8 is fixed by the locking block 113. This prevents the device from vibrating and causing the locking block 113 to rotate around the screw 112, which would affect the fixing effect on the filter frame 8.

[0020] The working principle of this embodiment is as follows: During use, the sample containing anthraquinone derivatives is first added to the extraction tank 23 through the feed pipe 10 at the top of the extraction tank 23. Simultaneously, the solvent in the solvent storage tank is transported to the extraction tank 23 through the solvent delivery pipe 9 under pressure difference. The flow regulating valve 22 on the solvent delivery pipe 9 can precisely control the solvent flow according to preset requirements, ensuring that the amount of solvent entering the extraction tank 23 meets the extraction process requirements, thus preparing for subsequent extraction. Then, the motor 13 at the top of the extraction tank 23 is started. The motor 13 drives the output end of the upright rod 14 to rotate and fix it in place. The stirring rod 15 on rod 14 rotates accordingly, thoroughly stirring and mixing the sample and solvent in extraction vessel 23, allowing the anthraquinone derivative to come into contact with and dissolve in the solvent as much as possible. Simultaneously, the heating wire 19, enclosed by the outer shell 2, activates on the outside of extraction vessel 23, heating the material inside to a suitable temperature environment, accelerating the dissolution of the anthraquinone derivative in the solvent. Furthermore, the ultrasonic generator 20 at the bottom of extraction vessel 23 generates ultrasonic waves, creating cavitation in the solution within the vessel, further promoting the better release of the anthraquinone derivative from the sample and its dissolution in the solvent. The combined effects of stirring, heating, and ultrasound efficiently achieve rapid extraction of anthraquinone derivatives. After extraction, the electrically controlled valve 21 on the discharge pipe 4 is opened, allowing the extract containing anthraquinone derivatives to flow into the filter box 5. Filter frames 8 with progressively smaller pore sizes are inserted sequentially from top to bottom into the slot 18 of the filter box 5. These filter frames 8 are held stable by the locking assembly 11. As the extract passes through each filter frame 8, impurities of different particle sizes are intercepted by the corresponding filter frames, achieving preliminary filtration of the extract and resulting in a relatively pure extract after impurity removal. The extract is drawn and collected at the bottom of the filter box 5. During this process, the sealing gasket 7 inside the square groove 6 on the filter box 5 plays a sealing role, preventing the extract from leaking from the joint between the groove 18 and the filter screen frame 8, ensuring the smooth progress of the filtration process. After filtration, the extract flows out through the discharge pipe 12 at the bottom of the filter box 5 and is collected in a container and placed on the platform inside the detection box 3. The detection box 3 is equipped with corresponding detection instruments (such as a spectroscopic detection module, a chromatographic detection module, etc.) to perform qualitative and quantitative analysis on the anthraquinone derivatives in the extract placed inside, such as using the ultraviolet- spectral detection module. The types of anthraquinone derivatives are determined by analyzing characteristic absorption peaks and functional group characteristics using visible and infrared spectrometers. The content is accurately determined using liquid chromatography and other principles via a chromatographic detection module. Finally, the detection results are displayed visually by a data processing and display module for operators to view and record. After a period of filtration, the filter frame 8 may need cleaning due to impurities. Operators can remove the filter frame 8 by operating the locking assembly 11. Specifically, rotating the knob 114 rotates the screw 112, which in turn moves the connected locking block 113.Release the contact between the locking block 113 and the filter frame 8 at the outer edge of the slot 18. Simultaneously, pull the limiting rod 24 on the locking block 113 out of the limiting groove 25 on the filter frame 8. The filter frame 8 can then be pulled out of the slot 18 for cleaning. After cleaning, reverse the steps to reinstall the filter frame 8 back into the slot 18. Then rotate the knob 114 to re-lock the locking block 113 against the edge of the filter frame 8 and insert the limiting rod 24 into the limiting groove 25, thus securing the filter frame 8. This allows it to continue in the next round of filtration, ensuring the continuous and stable operation of the entire device and enabling rapid extraction and detection of anthraquinone derivatives. If cleaning of the extraction tank 23 is required later, water can be injected into the extraction tank 23 through the feed pipe 10. The stirring rod 15 and the scraper 17 will work together to clean the inside of the extraction tank 23. Afterward, open the electrically controlled valve 21 of the discharge pipe 4 to discharge the wastewater.
