Description

Technical Field

[0001] The utility model relates to the technical field of polyvinylpyrrolidone processing, and particularly relates to a stirrer for polyvinylpyrrolidone polymerization. Background Art

[0002] Crosslinked polyvinylpyrrolidone, a pharmaceutical excipient, is a water-insoluble synthetic crosslinked homopolymer of N-vinyl-2-pyrrolidone. The preparation method of crosslinked polyvinylpyrrolidone requires that under nitrogen protection, with sodium hydroxide solution as an initiator, N-vinylpyrrolidone undergoes a polymerization reaction, and a phase change occurs during the crosslinked polymerization reaction. Specifically, the liquid in the early stage of the crosslinked polymerization reaction is converted into powder in the later stage of the crosslinked polymerization reaction to generate a crude product of crosslinked homopolymer, and then the crosslinked polyvinylpyrrolidone is obtained through centrifugal dehydration, spray drying, and sieving.

[0003] During the crosslinked polymerization process, a stirrer is usually used to stir the reaction raw materials. However, most of the existing stirrers used in polyvinylpyrrolidone production have relatively single stirring structures and stirring directions, and all the raw materials are usually added to the stirrer at one time for reaction during stirring, resulting in insufficient mixing and slow efficiency.

[0004] In the utility model with the Chinese patent publication number CN220514127U, a stirrer for polyvinylpyrrolidone crosslinked polymerization is proposed. Through the arranged feeding rod, horizontal stirring assembly, and vertical stirring assembly, the raw materials are gradually and evenly dispersed into the stirring tank for mixing and stirring during the rotation of the feeding rod along with the stirring rod, while avoiding powder deposition, ensuring that the powder at the lower end can repeatedly participate in the mixing reaction, and thus ensuring the quality of the crosslinked polyvinylpyrrolidone product. However, after researching the prior art and the above patent, it is found that the use effect of the existing stirring device still needs to be improved. Therefore, the utility model hereby provides a stirrer for polyvinylpyrrolidone polymerization. Summary of the Utility Model
