In the pharmaceutical industry, povidone K30 (PVP K30) is one of the new pharmaceutical excipients, mainly used as an adhesive for tablets and granules, a glidant for capsules, a detoxifying agent and lubricant for eye drops, a cosolvent for injections, a dispersant for liquid preparations, and a stabilizer for enzymes and heat-sensitive drugs.

[0003] After searching, the Chinese patent document announcement number: CN214288179U discloses a stirring device for cross-linking polymerization of cross-linked polyvinylpyrrolidone, including a stirring tank, a rotating motor is fixedly installed on the top of the stirring tank, and the output shaft of the rotating motor is fixedly connected to the top of the rotating rod. The stirring device for cross-linking polymerization of cross-linked polyvinylpyrrolidone drives the rotating rod to rotate by the rotating motor, that is, the stirring arc bar is driven by the stabilizing cone to stir the periphery of the rotating vertical cylinder, and the inner wall and bottom of the stirring tank are scraped by the stirring arc bar and the arc scraper synchronously, so that the material attached to the inner wall enters the stirring zone, and then the spiral propulsion blade is driven by the rotating rod to stir synchronously, and the spiral propulsion principle of the spiral propulsion blade is used to pass the bottom material of the stirring tank, and the rotating vertical cylinder is pushed to the top of the rotating vertical cylinder, and the stirring of the stirring blade is synchronously used to disperse the material to other spaces inside the stirring tank, so that the cross-linking polymerization of cross-linked polyvinylpyrrolidone is stirred more evenly and the reaction is more intense.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that the above patent mentions in the beneficial effects: "The stirring device for cross-linking polymerization of cross-linked polyvinylpyrrolidone, through the setting of the stirring tank, and the coordinated use of the rotating motor, the rotating rod, the stabilizing sleeve, the stirring blade, the feed valve pipe, the driving sleeve, the cross bar, the stabilizing cone, the driving collar plate, the fixing block, the driving scraper, the stirring arc strip, the spiral propulsion blade, the rotating vertical cylinder, the arc scraper and the discharge valve pipe, thereby playing a role in driving the rotating rod to rotate by the rotating motor, that is, driving the stirring arc strip to stir the periphery of the rotating vertical cylinder through the stabilizing cone, and synchronously scraping the inner wall and the bottom of the stirring tank through the stirring arc strip and the arc scraper, so that the material that fits the inner wall enters In the stirring zone, the spiral propulsion blade is driven by the rotating rod to stir synchronously. The spiral propulsion principle of the spiral propulsion blade is used to pass the bottom material of the stirring tank, and the rotating vertical cylinder is pushed to the top of the rotating vertical cylinder, and the stirring blade is used to stir synchronously to disperse the material to other spaces inside the stirring tank, so that the cross-linked polyvinylpyrrolidone cross-linking polymerization is stirred more evenly and the reaction is more intense. Although the above patent increases the reaction rate by stirring, in the specific operation process, the reaction product will be pushed to the bottom of the device, resulting in poor material discharge and the need to stop the machine for cleaning, which not only increases the production cost, but also delays the entire production line. Therefore, in view of the above shortcomings, a polyvinylpyrrolidone polymerization reaction equipment is proposed. Utility Model Content
