[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an online sampling device for sodium sulfonate generation, comprising a reaction vessel 1, a sampling cylinder 2 inside the reaction vessel 1, a sampling tube 3 inside the sampling cylinder 2, a sampling valve 4 fixedly connected to the outer wall of the sampling tube 3, a pump 6 on the outer wall of the sampling tube 3, a fixed seat 5 fixedly connected to the outer wall of the sampling valve 4, a fixed block 7 fixedly connected inside the fixed seat 5, a sliding rod 8 slidably connected inside the fixed block 7, a convex block 9 fixedly connected to the outer wall of the sliding rod 8, a connecting plate 10 slidably connected to the outer wall of the convex block 9, a support shaft 11 fixedly connected inside the connecting plate 10, both ends of the support shaft 11 being rotatably connected to the inside of the fixed block 7, a convex frame 12 slidably connected inside the support shaft 11, the outer wall of the convex frame 12 being slidably connected to the inside of the reaction vessel 1, a spring 13 fixedly connected to the outer wall of the convex frame 12, the outer wall of the spring 13 being fixedly connected to the inner wall of the reaction vessel 1, and a support assembly on the upper surface of the fixed seat 5.

[0026] Specifically, a cap is installed at the opening of the sampling cylinder 2 to open or close it. The sampling tube 3 is installed inside the reactor 1 through the sampling cylinder 2 to facilitate the extraction of sodium sulfonate from the reactor 1. The extraction pump 6 is connected to the sampling valve 4 through the sampling tube 3 to facilitate the extraction of sodium sulfonate into the sampling valve 4. The structure above the fixed seat 5 is supported by the fixed seat 5. Short rods are installed on the left outer wall of both the convex block 9 and the convex frame 12, and these short rods slide inside the connecting plate 10. They are used to move the convex block 9 and the convex frame 12 in opposite directions through the connecting plate 10 and the support shaft 11. Without external force driving the sliding rod 8, the spring force of the spring 13 pushes the convex frame 12 forward and slides inside the square plate of the reactor 1, thereby limiting the installation of the fixed seat 5.

[0027] Reference Figure 2 The support assembly includes a support plate 14, the lower surface of which is fixedly connected to the upper surface of the fixing seat 5, and the interior of the support plate 14 is disposed on the outer wall of the sampling tube 3.

[0028] Specifically, the support plate 14 is fixed by the fixing seat 5, and the sampling valve 4 has a groove inside that matches the outer wall of the sampling tube 3 to support the sampling tube 3.

[0029] Reference Figure 3 The outer wall of the convex block 9 is slidably connected to the inner wall of the fixed block 7, the outer wall of the fixed block 7 is slidably connected to the inside of the reactor 1, the middle outer wall of the convex frame 12 is slidably connected to the inside of the fixed block 7, and the lower surface of the fixed seat 5 is set on the upper surface of the reactor 1.

[0030] Specifically, the movement of the convex block 9 is restricted by the inner wall of the fixing block 7. The movement of the fixing block 7 is positioned by the groove provided on the square plate on the outer wall of the reactor 1, which matches the outer wall of the fixing block 7. The fixing seat 5 is in direct contact with the square plate on the outer wall of the reactor 1, which facilitates the installation of the fixing seat 5.

[0031] Reference Figure 4 and Figure 5The sampling valve 4 has a sampling canister 15 inside, and a concave gasket 16 and a sealing ring 17 are provided between the sampling canister 15 and the sampling valve 4. A hollow block 18 is fixedly connected to the outer wall of the sampling canister 15, and a U-shaped block 19 is slidably connected inside the hollow block 18. The upper surface of the U-shaped block 19 is fixedly connected to the lower surface of the sampling valve 4. Trapezoidal blocks 20 are slidably connected inside both the U-shaped block 19 and the hollow block 18. A sliding plate 21 is fixedly connected to the outer wall of the trapezoidal block 20. The outer wall of the sliding plate 21 is slidably connected to the inside of the hollow block 18. A telescopic rod 22 is fixedly connected to the outer wall of the sliding plate 21. A sliding plate 23 is fixedly connected to the outer wall of the telescopic rod 22. One end of a spring 24 is fixedly connected to the outer wall of the sliding plate 23. The other end of the spring 24 is fixedly connected to the outer wall of the sliding plate 21.

[0032] Specifically, an electronic valve is installed inside the sampling valve 4 to control the flow of material inside the valve. A sampling tank 15 is positioned below the sampling valve 4. Sodium sulfonate is collected under the combined action of the sampling valve 4 and gravity. A concave gasket 16 is installed at the opening of the sampling tank 15 to seal the connection between the tank and the sampling valve 4. A sealing ring 17 is also installed below the opening to seal the lower connection between the sampling tank 15 and the sampling valve 4, thus preventing accidental leakage of sodium sulfonate. A groove is provided inside the U-shaped block 19 to match the outer wall of the trapezoidal block 20. This allows the sliding plates 21 and 23 to move outward from the hollow block 18 under the elastic force of the telescopic rod 22. This allows the trapezoidal block 20 to slide into the U-shaped block 19 and engage, thus limiting the position of the hollow block 18 and allowing the sampling container 15 to be installed. The telescopic rod 22 connects the sliding plates 21 and 23 to prevent accidental slippage and also limits the range of movement of the sliding plates 21 and 23.

[0033] Working principle: When using this device, open the cap on the sampling cylinder 2, slide the sampling tube 3 through the sampling cylinder 2 into the interior of the reactor 1, place the fixing seat 5 on the square plate on the outer wall of the reactor 1, press the sliding rod 8 to make the convex block 9 slide forward, driving the connecting plate 10 and the support shaft 11 to rotate forward inside the fixing block 7, thereby driving the convex frame 12 to move backward, compressing the spring 13, causing the outer wall of the convex frame 12 to slide into the interior of the fixing block 7, and then slide the outer wall of the fixing block 7 into the square plate. Inside the plate, the fixing seat 5 is brought into contact with the square plate. Then the sliding rod 8 is released. Under the elastic force of the spring 13, the convex frame 12 is driven to slide forward. The outer wall of the convex frame 12 slides into the inside of the square plate, thereby quickly installing the fixing seat 5. By controlling the opening and closing of the sampling valve 4, the extraction pump 6 is started to extract sodium sulfonate from inside the reaction vessel 1 through the sampling tube 3. Finally, the sampling valve 4 is controlled to make the sodium sulfonate inside the sampling tube 3 flow to the sampling tank 15, thereby sampling the formation of sodium sulfonate online.

[0034] By pressing the sliding plate 21 and the sliding plate 23, the sliding plate 21 and the sliding plate 23 move towards the center of the hollow block 18, compressing the telescopic rod 22 and squeezing the spring 24. The sliding plate 21 and the sliding plate 23 drive the trapezoidal block 20 to slide out of the interior of the U-shaped block 19, no longer limiting it, so that the hollow block 18 can slide on the outer wall of the U-shaped block 19. This allows the sampling canister 15 and the hollow block 18 to be removed, making it easy to clean and replace the sampling canister 15 in a timely manner. During use, this device not only allows for the installation and disassembly of the entire sampling structure, but also enables the rapid disassembly of the sampling canister 15 for inspection or replacement.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
