Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane processing, in particular to polyurethane potting glue processing equipment which is convenient for sampling. Background Art

[0002] A reactor is a closed container, mainly used to realize physical or chemical reactions. Through the structural design and parameter configuration of the container, it can realize the heating, evaporation, cooling and low-speed mixing functions required by the process. The production of polyurethane potting glue involves a series of chemical reactions, such as the polymerization of polyols and diisocyanates of oligomers such as polyesters, polyethers and polydiolefins. The reactor provides a closed environment that can accurately control the temperature, pressure, stirring speed and other conditions required for the reaction, ensuring that the reaction proceeds in the predetermined direction, thereby obtaining the desired polyurethane potting glue product.

[0003] In order to ensure the production quality of polyurethane potting glue, it is necessary to test samples at different stages, so as to monitor the progress of the reaction and the quality of the product in real time, ensure that the final product meets the preset standards and specifications, and help understand the changes in the physical and chemical properties of the polyurethane potting glue in the reactor. By analyzing the samples, key parameters such as the temperature, viscosity, and degree of curing of the reaction system can be obtained to determine whether the reaction is proceeding as expected. Since the reactor is a large-scale equipment, when sampling the reactor, the contents at the top are often easier to take than those at the bottom. If there is stratification, precipitation or other uneven phenomena during the reaction process, the top sampling method is more likely to cause data distortion, which may be manifested as a misjudgment of the reaction rate, underestimation or overestimation of the product purity, etc. In addition, if only sampling is taken from the top, the obtained sample may not fully reflect the overall situation of the material in the reactor. This may lead to deviations in the analysis of the reaction process and product quality. Utility Model Content

[0033] Among them, the sampling port 3 is connected with the kettle cover 2, and the outer surface of the sampling tube 5 is provided with a rotating handle 6, which is fixedly connected to the sampling tube 5. Sampling can be completed by pulling the rotating handle 6 to rotate the sampling tube 5. The operation is simple and the convenience of sampling is improved.
