Water circulation chamber；Described agitating device includes being vertically arranged at the shaft at kettle center and distribution is arranged at outside the shaft
Auger leaf on surface, is evenly arranged with multiple through holes, during described shaft is on the blade of the auger leaf
Heat exchanger tube is provided with hollow structure and hollow inner chamber, the bottom of the shaft is arranged with driven gear, the frequency conversion drive
The driving gear being meshed with driven gear is arranged with the output shaft of motor.
Described water circulation chamber and heat exchanger tube can steam-out (SO) service and cooling water supply pipeline.
Preferably, the heat exchanger tube is disc type heat exchanger tube.
Preferably, the top of the kettle is provided with thermometer.
Preferably, the kettle is rustless steel kettle.
Operation principle of the present utility model is：
1st, NVP is sent into by kettle by NVP charging apertures, softened water is sent into by kettle by softened water charging aperture；
2nd, the variable frequency drive motors of agitating device are opened, agitating device work is stirred mixing；
3rd, steam heating is input into by water circulation chamber and heat exchange pipeline, temperature is risen to into 70 DEG C within the time of regulation；
4th, quantitative initiator, ammonia and hydrogen peroxide are added by adjuvant charging aperture；
5th, slowly it is warmed up to 82 DEG C, at this moment reaction starts and gradually violent；
6th, stop input steam, and observe the temperature change of thermometer；
7th, when temperature rises to 92 DEG C, cooling water is input into by water circulation chamber and heat exchanger tube, is cooled down, at this moment temperature meeting
Continuously rise to 95 DEG C to 98 DEG C；
8th, when temperature is down to 88～90 DEG C, input cooling water is stopped；
9th, maintain temperature to 90～95 DEG C, can be input into when temperature is low steam heating, and several times add initiator, ammonia,
Hydrogen peroxide drop is residual, and detects residual list, until qualified, that is, be polymerized and complete.
Raw material dosage is precisely controlled in production process；The rotation of auger leaf can be by polymeric material constantly from kettle
The bottom of body is transported to top, and during transport, polymeric material constantly drops from through hole again, and formation one is comprehensive
Three-dimensional stirring, makes stirring evenly；Using setting heat exchanger tube and the inner and outer wall in kettle in hollow shaft
Between water circulation chamber is set avoids heating and cool down the single of position, heating is cooled down evenly.
The beneficial effects of the utility model are：
1st, PVP polymeric kettles of the present utility model, can be used for the production of PVP and its series of products, optimization of process conditions, equipment
It is perfect, make easy to operate, and the product that different size is provided is required according to different user, can be controlled according to the requirement of client
The single residual content of product, can successfully produce the series of products such as qualified K17, K25, K30,60 and K90, meet different clients
Needs, production efficiency is high, and product quality gets a promotion, and index reaches the requirement of middle USA and Europe date pharmacopeia, and polymerization water is solidifying
Bear water, saved the operating cost of water purification machine, it is easy to operate, reduce the labor intensity of workman；
2nd, the stirring of omnibearing stereo formula, makes stirring evenly, the PVP better quality produced；
3rd, adopt to be arranged in hollow shaft and arrange between heat exchanger tube and the inner and outer wall in polymeric kettle water circulation chamber
Avoid heating and cool down the single of position, heating is cooled down evenly, the PVP better quality produced.
