Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically relating to a sampling and testing device for a reaction vessel used in the production of migration-resistant and anti-aging plasticizers. Background Technology

[0002] In the production process of migration-resistant and anti-aging plasticizers, real-time monitoring of the material status inside the reactor is crucial. Product quality, especially its migration resistance and anti-aging properties, highly depends on the precise control of the reaction process. This requires regular and reliable sampling of representative samples from the reactor for testing. However, existing reactor sampling devices generally suffer from a series of technical bottlenecks, making it difficult to meet the actual needs of producing such high-requirement chemicals.

[0003] High risk of contamination and oxidation: Traditional sampling methods (such as manual valve sampling or using simple sampling tubes) are difficult to effectively isolate air during the sampling process. Oxygen and moisture can easily penetrate the sample or reaction system, causing plasticizers to undergo oxidation, hydrolysis, and other aging reactions at the moment of sampling or during the subsequent short storage period. This results in severely distorted test results, failing to accurately reflect the actual performance of the materials inside the reactor (especially key anti-aging indicators). Simultaneously, external impurities may be introduced, contaminating the sample and even the entire reaction system. Existing sampling devices, especially those with storage chambers or sampling valves, often struggle to thoroughly clean the sampling channel and storage space. High-viscosity or easily solidified plasticizer materials are prone to residue formation, creating stubborn dirt. These residues not only contaminate... The contamination of the next sample can cause cross-contamination between batches, affecting the representativeness of the test. Long-term accumulation may also clog the sampling pipeline and reduce the reliability of the device. Many sampling processes still require a lot of manual intervention, such as manually operating valves, disassembling sampling components, and cleaning. This is not only inefficient and labor-intensive, but also increases the risk of operational errors and personnel exposure to hazardous chemicals. Insufficient automation also makes it difficult to achieve safe and convenient sampling in closed or high-pressure environments. For heterogeneous reactions or high-viscosity materials, static sampling points may not be able to obtain a fully mixed and representative sample. Simple sampling methods cannot ensure that the sample can accurately reflect the true state of the material at a specific location in the reactor (such as near the dead corner of the stirring vessel or the bottom of the vessel). Utility Model Content

[0004] The purpose of this invention is to provide a sampling and testing device for a reaction vessel used in the production of migration-resistant and anti-aging plasticizers, in order to solve the problems raised in the background art.

[0005] A sampling and testing device for a reaction vessel used in the production of migration-resistant and anti-aging plasticizers, including:

[0006] Reactor body;

[0007] A sampling assembly is located in the main body of the reactor vessel. The sampling assembly includes a sealing cap, an injection hole, an injection valve head, a sampling plug, a storage tank, a lifting plate, a receiving tube, a return spring, a scraper, and a driving assembly. The sealing cap is embedded in the inner wall of the reactor vessel body. The injection hole is located on the outer wall of the protruding end of the sealing cap. The injection valve head is embedded in the top opening of the sealing cap. The sampling plug is slidably embedded in the inner wall opening of the sealing cap. The storage tank is located on the outer wall of the sampling plug. The lifting plate is sleeved on the outer wall of the sampling plug. The scraper is slidably embedded in the inner wall of the receiving tube. One end of the return spring is fixedly located on the outer wall of the scraper, and the other end is fixedly located on the inner wall of the receiving tube. The scraper and the storage tank are matched, and the storage tank and the injection hole are matched. The sampling plug has a hole at its center. The driving assembly is located inside the main body of the reactor vessel.

[0008] Furthermore, the drive assembly includes a drive motor, a driving gear, and a driven gear.

[0009] Furthermore, the driving gear is fixedly disposed at the center of the outer wall of the output end of the drive motor, and the driven gear is sleeved on the bottom outer wall of the sampling plug, and the driving gear and the driven gear are meshed and connected.

[0010] Furthermore, a sampling cylinder and a scraping cylinder are fixedly installed on the outer wall of the main body of the reactor.

[0011] Furthermore, the output end of the sampling cylinder is fixedly disposed on the outer wall of the lifting plate, and the output end of the scraping cylinder is fixedly disposed on the outer wall of the scraping blade.

[0012] Furthermore, the opening of the sampling plug is connected to the valve via a hose and is installed in an external protective gas supply device. A sampling tube is embedded in the bottom opening of the reactor body. A base is fixedly installed on the bottom of the outer wall of the reactor body. A sealing plug is embedded in the top of the outer wall of the reactor body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The sampling assembly achieves a highly automated sampling operation. Driven by a sampling cylinder, the lifting plate and sampling plug are precisely raised and lowered. Combined with the pressurization process inside the reactor, the target material is actively forced into the storage tank of the sampling plug. This effectively avoids the problems of low efficiency, complex operation, and susceptibility to human error associated with traditional manual sampling. Automated operation reduces labor intensity and improves sampling efficiency. The assembly possesses excellent sealing and isolation performance. The sealing cap fits tightly with the reactor body, the injection hole is sealed by the injection valve head, and the sampling plug slides within the sealing cap, collectively forming a reliable sealed environment. This design strictly isolates the sampling process from direct contact with the reactor body and external air, minimizing the intrusion of external contaminants into the reactor and effectively inhibiting... This system prevents the escape of volatile or harmful substances from the reactor, ensuring production and environmental safety. It is particularly suitable for the production of migration-resistant and anti-aging plasticizers with high purity requirements. The component integrates a highly efficient self-cleaning function after sampling. After the sampling plug descends into place, the drive motor drives the sampling plug to rotate through the meshing of the drive and driven gears. At the same time, the scraping cylinder pushes the scraping blade to extend against the resistance of the return spring, thoroughly scraping the inner wall of the storage tank. This design ensures that the material remaining on the inner wall of the storage tank after each sampling can be removed in a timely and effective manner and discharged through the sampling tube. This in-situ cleaning mechanism fundamentally solves the problem of residue contamination of subsequent samples, ensuring the independence and purity of each sampling, thereby significantly improving the accuracy and reliability of the test data.
