Description

Technical Field

[0001] This utility model belongs to the technical field of microwave extraction equipment, specifically, it relates to a microwave extraction device for detecting pesticide and veterinary drug residues. Background Technology

[0002] Animal-derived foods refer to all edible animal tissues, as well as eggs and milk, including meat and its products, aquatic animal products, etc. In order to improve food safety, pesticide and veterinary drug residues need to be tested before processing. Microwave energy is rapidly converted into heat energy, which causes the temperature inside the cells to rise rapidly. When the pressure inside the cells exceeds the cells' tolerance, the cells will rupture, and the active ingredients will flow out from the cells and dissolve in the extraction medium at a lower temperature. After further filtration and separation, the extracted components can be obtained. Therefore, microwave extraction devices are widely used in the detection of pesticide and veterinary drug residues in animal-derived foods.

[0003] According to the publicly available announcement (CN222173155U), a microwave extraction device for pretreatment of pesticide and veterinary drug residues in animal-derived foods is disclosed. This device "includes a microwave chamber, with a microwave generator installed on the inner wall of the chamber, a placement mechanism inside the chamber, a beaker placed within the placement mechanism, a top cover inserted into the top of the beaker, an extraction mechanism on the top of the microwave chamber, and an auxiliary mechanism inside the beaker. The beneficial effects are: a mounting ring is installed on the outside of the connecting tube, and a stirring blade is fixedly connected to the outer wall of the mounting ring. The stirring blade stirs the solution in the beaker, making the solution in the beaker heat more evenly; the mounting ring is slidably connected to the outer wall of the connecting tube, and a power component drives the mounting ring to move the stirring blade up and down, further improving the uniformity of heating of the solution in the beaker; the connecting tube is slidably connected to the air inlet pipe, and an electric push rod drives a lifting plate to move the connecting tube, top cover, and stirring blade upwards, facilitating the removal and placement of the beaker."

[0004] When extracting a solution, the solution contains a large number of impurities to be detected. The above structure proposes to stir the solution in the beaker by stirring the stirring blade to make the solution in the beaker heat evenly. However, this can easily cause the solution to mix with the impurities to be detected. After extraction, the solution needs to be filtered to separate the impurities in the solution. Usually, filtration or static precipitation is used, which requires a lot of time for solid-liquid separation, thus affecting the extraction efficiency.

[0005] To address the aforementioned issues, this application proposes a microwave extraction device for detecting pesticide and veterinary drug residues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A microwave extraction device for detecting pesticide and veterinary drug residues includes a housing 1, a fixed housing 2 fixedly connected to the bottom of the housing 1, a drive motor 3 fixedly connected inside the fixed housing 2, a rotating shaft 4 fixedly connected to the output end of the drive motor 3, a rotating disk 5 fixedly connected to the end of the rotating shaft 4 away from the drive motor 3, an installation groove 9 formed on the inner side wall of the rotating disk 5, and a test tube 10 inserted into the inner side wall of the rotating disk 5. The outer side wall of the test tube 10 is adapted to the inner side wall of the installation groove 9. The fixed housing 2 provides limiting support for the drive motor 3, allowing the drive motor 3 to stably drive the rotating shaft 4 to rotate. The end of the rotating shaft 4 away from the drive motor 3 is fixedly connected to the center of the bottom of the rotating disk 5, thus enabling the rotating disk 5 to operate stably. The solution is inserted into the installation groove 9 inside the rotating disk 5 through the test tube 10. When the rotating disk 5 rotates, it drives the test tube 10 inside to rotate, thereby performing solid-liquid separation of the solution inside the test tube 10, reducing the particulate matter floating in the solution, and effectively improving the extraction efficiency of the solution.

[0022] Reference Figure 3 The rotating disk 5 has a rotating groove 6 on its top, and a cover plate 8 is attached to the top of the rotating disk 5. A sealing ring 7 is fixedly connected to the bottom of the cover plate 8. The outer side wall of the sealing ring 7 is adapted to the inner side wall of the rotating groove 6. The bottom of the cover plate 8 is attached to the top of the rotating disk 5, and the sealing ring 7 at the bottom of the cover plate 8 is inserted into the rotating groove 6 on the top of the rotating disk 5, so that the cover plate 8 seals the top of the rotating disk 5, thereby allowing the gas extracted by the solution to be collected through the rotating disk 5.

[0023] Reference Figure 2-3A heating ring 11 is fixedly connected to the bottom of the outer casing 1 of the device. A heating groove 12 is provided on the inner side wall of the heating ring 11. A heating wire 13 is provided inside the heating ring 11. By positioning the rotating disk 5 inside the heating ring 11 and installing the heating wire 13 in the heating groove 12 inside the heating ring 11, the heating wire 13 is microwave heated inside the heating groove 12, so that the heat is effectively conducted to the inside of the rotating disk 5. After the rotating disk 5 performs solid-liquid separation of the solution, it can extract the solution. When the rotating disk 5 rotates, it can effectively make the inside of the test tube 10 heat evenly and prevent uneven heating.

[0024] Reference Figure 2-3 An exhaust pipe 14 is fixedly connected to the top of the cover plate 8. A telescopic pipe 15 is connected to the top of the exhaust pipe 14. An inclined pipe 16 is connected to the end of the telescopic pipe 15 away from the exhaust pipe 14. The exhaust pipe 14 on the top of the cover plate 8 is connected to the interior of the cover plate 8, so that the gas extracted inside the rotating disk 5 is transported through the cover plate 8 to the interior of the exhaust pipe 14. The gas is transported through the exhaust pipe 14 and the telescopic pipe 15 to the interior of the condenser 17. The inclined pipe 16 is inclined so that when the gas is liquefied inside the inclined pipe 16, it can slide along the inclined pipe 16 to prevent the solution from flowing back.

[0025] Reference Figure 4 The inclined tube 16 is connected to a condenser tube 17 at the end away from the telescopic tube 15. A fixing frame 18 is fixedly connected to the outer wall of the condenser tube 17. A collection frame 19 is attached to the inner bottom of the equipment shell 1. The collection frame 19 is located directly below the condenser tube 17 and is connected to the condenser tube 17 through the inclined lower end of the inclined tube 16, so that the condenser tube 17 cools the incoming gas, thereby performing a liquefaction operation. The liquefied solution flows into the interior of the collection frame 19 for collection. The condenser tube 17 is limited and fixed by the fixing frame 18.

[0026] Reference Figure 1 The outer wall of the device housing 1 is provided with a display screen 20 and a control button 21. The bottom of the device housing 1 is fixedly connected to a support leg 22. The end of the support leg 22 away from the device housing 1 is fixedly connected to an anti-slip seat 23. The display screen 20 on the outer wall of the device housing 1 displays the temperature inside the device housing 1. The control button 21 can adjust the temperature of the heating wire 13. The support leg 22 and the anti-slip seat 23 at the bottom of the device housing 1 can support the device housing 1. The anti-slip seat 23 can prevent the device housing 1 from sliding.

[0027] Working principle: By extending and retracting the telescopic tube 15, the cover plate 8 is disengaged from the top of the rotating disk 5, allowing the solution to be placed inside the test tube 10. The test tube 10 is then inserted into the mounting groove 9. The rotating disk 5 is rotated by the drive motor 3, thereby separating the solid and liquid components of the solution inside the test tube 10 and reducing the content of particulate impurities in the solution. The solution inside the rotating disk 5 is microwave-extracted by the heating wire 13 inside the heating ring 11, allowing the solution inside the test tube 10 to be extracted. The extracted gas enters the exhaust pipe 14 through the cover plate 8 and is then transported to the inclined tube 16. Under the transport of the inclined tube 16, the gas is then transported to the condenser tube 17 for liquefaction. The liquefied solution is collected by the collection frame 19 at the bottom of the condenser tube 17.
