Description

Technical Field

[0001] This utility model relates to the field of chromatography technology, specifically to a high-performance liquid chromatograph that facilitates the recovery of condensate. Background Technology

[0002] High-performance liquid chromatography (HPLC) is a commonly used analytical chemistry instrument widely applied in chemistry, biology, and medicine to separate and detect components in mixtures. During HPLC operation, the detector (such as an ultraviolet detector or a fluorescence detector) generates heat. To ensure detection accuracy, the detector typically requires cooling. During cooling, water vapor in the air condenses on the outer wall of the detector, forming condensate. If this condensate is not collected promptly, it will drip into the chromatograph or onto the lab bench, potentially causing short circuits, corrosion, and other damage to internal components. It can also contaminate the experimental environment, affecting the safety and accuracy of the experiment. In existing technologies, some high-performance liquid chromatographs (HPLC) have a simple water collection tray outside the detector to collect condensate. However, the collection area of ​​the tray is limited, condensate easily overflows from the edge, and cleaning the condensate inside the tray is inconvenient, requiring frequent disassembly of instrument components, which is cumbersome and affects experimental efficiency. Therefore, there is an urgent need for an HPLC system that facilitates condensate recovery to solve these problems. Utility Model Content

[0019] 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.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a high-performance liquid chromatograph for convenient recovery of condensate includes a detector 1. A condenser hood 2 is fixedly connected to one side of the outer wall of the detector 1. A flow guiding component for guiding condensate is provided on the bottom inner wall of the condenser hood 2. A threaded tube 5 is fixedly connected to the bottom of the condenser hood 2. The threaded tube 5 is connected to the flow guiding component. A collection component is provided at one end of the threaded tube 5 extending to the outside of the condenser hood 2. The condenser hood 2 is equipped with a scraping component inside to scrape off the condensate adhering to the outer wall of one side of the detector 1. The condenser hood 2 is equipped with a scraping component inside to scrape off the condensate adhering to the outer wall of one side of the detector 1. The condensate adhering to the inclined bottom inner wall of the condenser hood 2 cooperates with the radial guide channel 12. Combined with the active scraping action of the scraper 6, the collection efficiency of the condensate is greatly improved. The detachable design of the collection bottle 3 and the protective function of the limiting plate 4 ensure the safety of use and avoid damage to the instrument and environmental pollution caused by the condensate dripping. The practicality and reliability of the instrument are greatly improved.

[0021] Furthermore, the cross-section of the condenser hood 2 is a right-angled trapezoid, and the bottom inner wall of the condenser hood 2 is inclined. The design of the right-angled trapezoidal cross-section of the condenser hood 2 can adapt to the shape of the detector 1 to achieve tight installation and reserve movement space for the scraping component. The inclined bottom inner wall can guide the condensate to the flow guide component by gravity. The two work together to solve the problems of leakage and poor adaptability of traditional structures, improve the efficiency of condensate collection, and lay the foundation for convenient use of the collection component.

[0022] Furthermore, the collection assembly includes a collection bottle 3 threadedly connected to the outer circumference of the threaded tube 5. A limiting plate 4 is fixedly connected to the outer circumference of the threaded tube 5 to prevent the collection bottle 3 from being over-installed. The limiting plate 4 on the threaded tube 5 can prevent the collection bottle 3 from being over-installed and ensure the connection is sealed. At the same time, the threaded connection design between the collection bottle 3 and the threaded tube 5 allows for cleaning of condensate without frequent disassembly of instrument parts, making operation convenient and improving experimental efficiency.

[0023] Furthermore, the flow guiding assembly includes a first collection tank 11, a flow guiding tank 12, and a second collection tank 13 formed on the inner wall of the bottom of the condenser shroud 2. The first collection tank 11 is connected to the second collection tank 13 through the flow guiding tank 12. The cross-section of the first collection tank 11 is rectangular, and the cross-section of the second collection tank 13 is circular. The threaded pipe 5 is connected to the second collection tank 13. With the help of the flow guiding assembly that is radially distributed on the inner wall of the bottom, the condensate first flows into the first collection tank 11, and then is efficiently guided to the second collection tank 13 through the flow guiding tank 12. Finally, it is introduced into the collection bottle 3 through the threaded pipe 5 connected to the second collection tank 13.

[0024] Furthermore, a baffle 7 is fixedly connected to one side of the outer wall of the condenser hood 2 to prevent condensate from flowing out from the end face. The guide groove 12 is radially distributed on the bottom inner wall of the condenser hood 2. The baffle 7 on one side of the outer wall can effectively prevent condensate from overflowing from the end face, ensuring that all condensate is collected in the condenser hood 2, thus avoiding the overflow problem caused by the limited collection range of the existing water receiving tray.

[0025] Furthermore, the scraping assembly includes a motor 8 fixedly connected to the outer wall of one side of the condenser shroud 2. A threaded screw 14 is fixedly connected to the output end of the motor 8. A threaded sleeve 15 is threadedly connected to the outer circumference of the threaded screw 14. A scraper 6 is fixedly connected to the outer wall of one side of the threaded sleeve 15. One side of the scraper 6 contacts the outer wall of one side of the detector 1. The scraping assembly inside the condenser shroud 2 drives the threaded screw 14 to rotate through the motor 8, causing the threaded sleeve 15 and the scraper 6 fixed thereto to slide along the outer wall of the detector 1. This can effectively scrape off the condensate adhering to the surface of the detector 1, solving the problem of difficult collection of condensate residue.

[0026] Furthermore, a through groove 9 is provided on the top outer wall of the condenser shroud 2. A slider 16 is slidably connected inside the through groove 9. The slider 16 is fixedly connected to the threaded sleeve 15. A slide plate 10 is fixedly connected to the other side of the slider 16. The slide plate 10 is slidably connected to the top outer wall of the condenser shroud 2. The cooperation of the through groove 9, the slider 16 and the slide plate 10 ensures the stability of the scraper 6 during the sliding process, and further improves the comprehensiveness of condensate collection.

[0027] Working principle: During operation, the detector 1 is first fully covered by the condenser hood 2, which has a right-angled trapezoidal cross-section and an inclined bottom inner wall. With the help of the baffle 7 on one side of the outer wall, the condensate can be effectively prevented from overflowing from the end face, ensuring that all the condensate is collected in the condenser hood 2, thus avoiding the overflow problem caused by the limited collection range of the existing water collection tray. Once condensate forms, the condensate flows into the first collection tank 11 first, then is efficiently guided to the second collection tank 13 via the guide tank 12, and finally introduced into the collection bottle 3 through the threaded tube 5 connected to the second collection tank 13. The limiting plate 4 on the threaded tube 5 can prevent the collection bottle 3 from being over-installed and ensure the connection is sealed. At the same time, the threaded connection design between the collection bottle 3 and the threaded tube 5 makes it possible to clean the condensate without frequently disassembling instrument parts, making the operation convenient and improving experimental efficiency. On the other hand, the scraping component inside the condenser hood 2 drives the threaded screw 14 to rotate via the motor 8, causing the threaded sleeve 15 and the scraper 6 fixed thereto to slide along the outer wall of the detector 1. This effectively scrapes off the condensate adhering to the surface of the detector 1, solving the problem of difficult collection of condensate residue. The cooperation of the through groove 9, the slider 16 and the slide plate 10 ensures the stability of the scraper 6 during the sliding process, further improving the comprehensiveness of condensate collection. In the overall structure of this chromatograph, the cooperation between the inclined bottom inner wall of the condenser hood 2 and the radial guide groove 12, combined with the active scraping action of the scraper 6, greatly improves the condensate collection efficiency. The detachable design of the collection bottle 3 and the protective function of the limiting plate 4 ensure safety in use and avoid instrument damage and environmental pollution caused by condensate dripping, significantly improving the practicality and reliability of the instrument.
