Embodiment 1
[0017] The agitator used for emulsion method polymerization to produce polyvinyl chloride paste resin polymerization kettle, agitator 15 includes agitator shaft 18, annular pipe type agitator paddle 17, agitator 15 is installed in polymerization kettle 1, agitator shaft 18 is hollow type, A ring-type stirring paddle 17 is installed on the stirring shaft 18. The inside of the stirrer 15 is fed with circulating cooling water. The stirrer 15 is provided with a cooling water inlet 12 and a cooling water outlet 11. Fluorine packing seal 10; the ratio of the diameter of the ring-type stirring paddle 17 of the agitator 15 to the diameter of the kettle body 2 is 0.48:1, and the clamp between the center line of the ring pipe of the ring-type stirring paddle 17 of the agitator 15 and the stirring shaft 18 The angle is 3°; the ring-type stirring paddle 17 and the stirring shaft 18 are connected by detachable countersunk screws 22; the lower part of the stirring shaft 18 and the ring-type ...
Embodiment 2
[0021] Embodiment 2 is basically the same as Embodiment 1, except that the ratio of the diameter of the ring-type stirring paddle 17 of the stirrer 15 to the diameter of the kettle body 2 is 0.45:1, and the center of the ring pipe of the ring-type stirring paddle 17 of the stirrer 15 is 0.45:1. The angle between the line and the central line of the stirring shaft 18 is 4°;
[0022] The kettle body 2 has a volume of 130 cubic meters, an aspect ratio of 2.6, a height of 30 meters, and a nominal diameter of 4.0 meters.
