[0002] Polymer particles are a material composed of polymer molecules, which have the characteristics of small particle size, good dispersibility and strong adjustability. They are functional materials. The finished polymer particles of the ultra-high pressure device are sent to the finished product silo after degassing. Sampling and analysis are required before packaging in the finished product silo. When sampling, on-site operators are required to take samples at the sampling port at the bottom of the finished product silo.
[0003] The finished polymer granule silo of the ultra-high pressure device is located at a high position, and the sampling port at the bottom of the finished product silo is set at the bottom of the finished product silo. Each time the on-site operator takes a sample, he needs to climb the stairs to the bottom of the finished product silo to take a sample, which increases the workload and physical exertion of the personnel. At the same time, the polymer granules are pneumatically transported from the degassing silo to the finished product silo, and the polymer granules are not mixed evenly. The sampling and analysis error at the bottom of the finished product silo is large, and the analysis data is inaccurate. Therefore, an automatic polymer granule sampling device that can uniformly and quantitatively sample polymer granules is needed.
[0004] In view of this, the utility model provides a polymer particle timing and quantitative automatic sampling system. Utility Model Content

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0022] Example: Figure 1-4 As shown, the device comprises a degassing silo 1 for storing degassing polymer particles, a conveying pipe 2 for conveying polymer particles is installed at the bottom of the degassing silo 1, a conveying component 21 for providing conveying power for polymer particles is installed at one end of the conveying pipe 2, a sampling line pipe 3 for sampling the conveyed polymer particles is installed inside the conveying pipe 2, and a sampling hole for sampling the outflow of polymer particles flowing in the sampling line pipe 3 is opened on the outer surface of the sampling line pipe 3, fixing components 4 are installed at both ends of the sampling line pipe 3, a limiting component 5 is installed inside the sampling line pipe 3, and a finished product silo 6 for receiving the conveyed polymer particles is installed at the other end of the conveying pipe 2;
[0023] The sampling line tube 3 is fixedly installed in the conveying pipeline 2 by the fixing component 4, so that when the conveying component 21 conveys the polymer particles in the degassing silo 1, the polymer particles pass through the conveying pipeline 2 and the sampling holes of the sampling line tube 3, so that the polymer particles can flow out of the sampling holes, and the limiting component 5 can limit the outflow amount of the polymer particles flowing out of the sampling holes. The polymer particles flow from the degassing silo 1 into the finished product silo 6 in the conveying pipeline 2. Under the control of the limiting component 5, the polymer particles can flow out of the sampling holes in the sampling line tube 3 evenly and quantitatively, which is convenient for collecting and detecting the polymer particles.
[0024] First, the specific structure of the conveying component 21 is disclosed. The conveying component 21 includes a conveying pneumatic pump 201. The air outlet at one end of the conveying pneumatic pump 201 is fixedly installed on the conveying pipeline 2 to provide conveying air force inside the conveying pipeline 2.
[0025] The conveying pneumatic pump 201 can provide compressed circulating air to the conveying pipeline 2, so that the polymer particles in the degassing silo 1 flow into the conveying pipeline 2 for conveyance.
[0026] According to the above disclosure of the specific structure of the fixing assembly 4, the fixing assembly 4 includes a fixing ring 401 fixedly installed at both ends of the sampling line tube 3, a sealing rubber pad is installed on the inner wall of the fixing ring 401, a mounting interface is opened on the outer surface of the conveying pipeline 2, a docking ring 402 is fixedly installed on the outer side of the mounting interface, and the fixing ring 401 and the docking ring 402 are fixedly connected by fixing bolts;
[0027] The fixing rings 401 fixedly installed at both ends of the sampling line tube 3 are connected to the docking ring 402 of the installation interface on the conveying pipeline 2, and then fixed by multiple fixing bolts, so that the sampling line tube 3 can be installed on the conveying pipeline 2 in a sealed manner.
[0028] According to the above disclosure of the specific structure of the limiting component 5, the limiting component 5 includes a discharge pipe 501 for receiving the polymer particles flowing out of the sampling hole, a mounting block 502 is fixedly installed on the outer surface of the discharge pipe 501, and a groove penetrating the discharge pipe 501 and the mounting block 502 is provided on the contact surface between the discharge pipe 501 and the mounting block 502, and a cylindrical limiting plate 503 is provided inside the groove for limiting the polymer particles flowing out of the discharge pipe 501, and a rotating rod 504 for adjusting the limiting plate 503 up and down is fixedly installed on the top of the limiting plate 503.
[0029] The top of the rotating rod 504 passes through the slot and extends to the outside of the mounting block 502. The limiting plate 503 is installed inside the discharge pipe 501 to limit the outflow of polymer particles flowing into the discharge pipe 501. The inner wall of the sampling line tube 3 is fixedly installed with a blocking block 7, which is arranged above the sampling hole of the sampling line tube 3 to block the circulating polymer particles from entering the sampling hole. A sampling bucket 8 is installed at one end of the discharge pipe 501 to collect the polymer particles to be sampled.
[0030] When sampling the polymer particles flowing in the conveying pipe 2, the polymer particles flowing in the conveying pipe 2 will pass through the sampling line tube 3 connected to the conveying pipe 2. The blocking block 7 above the sampling hole on the inner wall of the sampling line tube 3 can block the flowing polymer particles. The aperture of the sampling hole is calculated so that the aperture of the sampling hole can pass a fixed amount of polymer particles at a fixed time, so that the polymer particles enter the discharge pipe 501 connected to the sampling hole. When sampling is required, the rotating rod 504 is rotated to raise the limiting plate 503, so that the discharge pipe 501 is connected to the sampling barrel 8, and the polymer particles that flow out evenly and quantitatively are collected to facilitate subsequent testing. When sampling is not required, the rotating rod 504 is rotated in the opposite direction to lower the limiting plate 503 to block the discharge pipe 501, so as to achieve the effect of automatic quantitative and uniform sampling of polymer particles.
[0031] In summary, the working principle of this solution is as follows:
[0032] When sampling the polymer particles, after the degassing bin 1 is degassed, the polymer particles flow out from the bottom conveying pipe 2, and the conveying pneumatic pump 201 conveys air in the conveying pipe 2 to deliver the polymer particles from the conveying pipe 2 to the finished product bin 6. The sampling hole opened on the sampling line pipe 3 installed in the middle of the conveying pipe 2 can block the blocking block 7 and allow the circulating polymer particles to flow into the discharge pipe 501 in a quantitative and uniform manner from the sampling hole. The limiting plate 503 in the discharge pipe 501 is rotated by the rotating rod 504. The discharge pipe 501 is opened and closed by rotating and lifting. When sampling is required for polymer particle transportation, the rotating rod 504 is rotated to open the limiting plate 503, and the polymer particles in the discharge pipe 501 flow into the sampling barrel 8. A slight positive pressure is maintained in the sampling barrel 8 to prevent impurities from entering, thereby ensuring clean sampling and facilitating analysis and testing of the polymer particles, so that the obtained polymer particle samples are representative and the analysis results are accurate. When sampling and testing are not performed, the limiting plate 503 is closed to prevent the polymer particles from flowing and are normally transported to the finished product silo 6.
