[0017] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.

[0018] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the utility model provides a liquid separation device technical solution for analyzing dioxin-like pollutants in fish oil: including a housing 1, a top cover 2 is arranged on the top of the housing 1, an inner tank 11 is arranged inside the housing 1, a precipitation separation chamber is arranged inside the inner tank 11, a liquid separation chamber 14 is arranged between the inner tank 11 and the housing 1, a material pipe 22 is arranged on the top of the top cover 2, the material pipe 22 extends into the inner tank 11, a liquid discharge interface 12 is arranged on the outer wall of the housing 1, and a liquid discharge pipe 13 is installed on the liquid discharge interface 12.

[0019] Among them, the liquid discharge pipe 13 is arranged in a concave shape and is distributed obliquely downward, and the liquid discharge interface 12 is located below the inner tank 11. This design ensures that during the liquid discharge process, the liquid can flow out smoothly, and at the same time avoids liquid splashing, thereby reducing the risk of sample cross-contamination.

[0020] Among them, the precipitation separation chamber in the inner tank 11 is used for liquid precipitation separation, and after overflow, it enters the liquid separation chamber 14. The liquid separation chamber 14 is used for the liquid to stand and precipitate again. Through this design, the dioxin-like pollutants in the fish oil can be effectively separated, improving the efficiency and accuracy of liquid separation.

[0021] Among them, multiple groups of buckles 23 are arranged on the top edge of the housing 1, and a pressing hook 24 is arranged on each group of buckles 23. The pressing hook 24 is used to fix the top cover 2. A handle 21 is installed on the top of the top cover 2, and a sealing ring is arranged at the bottom of the top cover 2 for sealing the housing 1. This structural design makes the disassembly and assembly of the device simple and convenient, improving the operation convenience.

[0022] Among them, the housing 1, the inner tank 11, the top cover 2, the liquid discharge pipe 13, the material pipe 22, the buckles 23 and the pressing hooks 24 are all made of corrosion-resistant materials to ensure that the device maintains good performance during long-term use. In addition, the inner wall surfaces of the housing 1 and the inner tank 11 are specially treated to reduce the adhesion of the liquid on the surface, further improving the liquid separation efficiency.

[0023] In this embodiment, the fish oil sample to be detected is injected into the precipitation separation chamber in the inner tank 11 through the material pipe 22. Under appropriate conditions, such as temperature and standing time, the dioxin-like pollutants are effectively separated from other components in the fish oil. The separated liquid enters the liquid separation chamber 14 through overflow and further stands and precipitates.

[0024] In the liquid separation chamber 14, the dioxin-like pollutants will be further enriched in a specific liquid layer. At this time, by operating the liquid discharge pipe 13, the upper clean liquid can be discharged, while the liquid rich in dioxin-like pollutants remains in the liquid separation chamber 14. Since the liquid discharge pipe 13 is designed in a concave shape, the liquid will not splash during the discharge process, ensuring the purity of the sample.

[0025] The liquid separation device for analyzing dioxin - like pollutants in fish oil of the present utility model not only improves the accuracy and efficiency of detection, but also has a simple structure, convenient operation and is easy to maintain, which is especially suitable for the use requirements of modern food safety testing laboratories.
