[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Please refer to Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a sampling and testing device for demulsifier raw material pipeline transportation, comprising: a sampling and testing component 2 installed on the demulsifier transportation pipeline 1, the sampling and testing component 2 including a sealing shell 201, a densitometer 2011 for demulsifier density detection installed on the sealing shell 201, a connecting pipe 202 installed at the bottom of the sealing shell 201, and the bottom of the sealing shell 201 being interconnected with the demulsifier transportation pipeline 1 through the connecting pipe 202.

[0028] By adopting the above technical solution, the sealing shell 201 is directly connected to the demulsifier delivery pipeline 1, and the connecting pipe 202 and control valve 2021 are used to realize the direct flow detection of demulsifier, avoiding the cumbersome and time-consuming traditional offline detection and significantly improving the detection efficiency. Furthermore, the design utilizes the pressing pad 20331 and pressing plate 2033 to drive the pressing rod 2032 to lower the sealing plate 2031, pushing the demulsifier back into the demulsifier delivery pipeline 1, thus avoiding sample waste. At the same time, the direct online detection method avoids interference from the external environment on the sample, improving the accuracy and reliability of the detection results. The device is easy to operate, has a compact structure, and the safety of the sealing plate 2031 is enhanced by the buffer component 204. Overall, it provides an efficient, accurate, and safe solution for real-time monitoring of the quality of demulsifier raw materials in chemical production.

[0029] To achieve flexible control of the flow between the demulsifier and the sealing shell 201 in the demulsifier delivery pipeline 1, in this embodiment: a control valve 2021 is installed on the connecting pipe 202 to control the flow between the demulsifier and the sealing shell 201 in the demulsifier delivery pipeline 1. By opening and closing the control valve 2021, the flow of the demulsifier can be precisely controlled according to the actual testing requirements, avoiding the inconvenience and sample waste caused by the inability to flexibly control the sample flow in traditional testing methods, and greatly improving the testing efficiency and accuracy.

[0030] To achieve the function of pushing the demulsifier inside the sealing shell 201 into the demulsifier delivery line 1, in this embodiment: a pressing component 203 for pushing the demulsifier inside the sealing shell 201 into the demulsifier delivery line 1 is also installed inside the sealing shell 201. The pressing component 203 includes a sealing plate 2031 slidably disposed inside the sealing shell 201. The center of the sealing plate 2031 is sealed and slidably connected to the detection head of the densitometer 2011. Pressing rods 2032 are fixedly connected to both sides of the top of the sealing plate 2031. The top of the pressing rods 2032 moves through the sealing shell 201 and extends to the outside of the sealing shell 201 where a pressing plate 2033 is fixedly connected. After the detection is completed, the pressing plate 2033 is pressed by the pressing pad 20331, which drives the pressing rods 2032 to move down, thereby pushing the sealing plate 2031 to push the demulsifier inside the sealing shell 201 back into the demulsifier delivery line 1, avoiding sample waste and making the operation simple and convenient.

[0031] To enhance the sealing performance between the sealing plate 2031 and the sealing shell 201 and prevent demulsifier leakage, in this embodiment: a sealing ring 20311 matching the sealing shell 201 is fitted on the sealing plate 2031; a sealing sleeve 20312 is installed at the center of the sealing plate 2031, corresponding to the position of the density meter 2011 detection head, to slide in a sealing manner with the density meter 2011 detection head. The cooperation between the sealing ring 20311 and the sealing sleeve 20312 ensures the sealing performance of the sealing plate 2031 when it slides inside the sealing shell 201, effectively preventing demulsifier leakage and improving the reliability and safety of the detection device.

[0032] To facilitate the operator in pressing the pressing plate 2033, in this embodiment, a pressing pad 20331 is fixedly connected to the top of the pressing plate 2033. The design of the pressing pad 20331 increases the contact area between the operator and the pressing plate 2033, making the pressing operation more effortless and comfortable, and improving the humanization of the detection device.

[0033] To buffer and protect the sealing plate 2031 and extend its service life, in this embodiment, a buffer assembly 204 for buffering and protecting the sealing plate 2031 is also installed on the top of the inner wall of the sealing shell 201 and at the position corresponding to the sealing plate 2031. The buffer assembly 204 includes a buffer spring 2042 fixedly connected to the top of the inner wall of the sealing shell 201, a buffer plate 2041 fixedly connected to the bottom of the buffer spring 2042, and a buffer pad 20421 fixedly connected to the bottom of the buffer plate 2041. When the sealing plate 2031 moves upward, the buffer assembly 204 can effectively buffer it, avoiding a violent collision between the sealing plate 2031 and the top of the inner wall of the sealing shell 201, thereby extending the service life of the sealing plate 2031 and improving the stability and reliability of the detection device.

[0034] The working principle of this utility model is as follows: The sealing shell 201 is connected to the demulsifier delivery pipeline 1 via the connecting pipe 202. During testing, the control valve 2021 on the connecting pipe 202 is opened, allowing the demulsifier inside the demulsifier delivery pipeline 1 to flow into the sealing shell 201 through the connecting pipe 202. This compresses the sealing plate 2031, causing it to move upwards. Under the buffering effect of the buffer assembly 204, the sealing plate 2031 is protected. At this time, the demulsifier is monitored in real time online using the densitometer 2011. After the test is completed, the pressing pad 20331 presses the pressing plate 2033, causing the pressing rod 2032 to move downwards. This pushes the sealing plate 2031 back into the demulsifier delivery pipeline 1. Then, the control valve 2021 is closed, completing the entire testing process.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
