Description

Technical Field

[0002] As we all know, the polyperfluoroethylene propylene (PFA) resin coagulation device is a device used to accelerate the polymerization reaction of PFA resin. PFA is a high-performance fluoroplastic with excellent chemical corrosion resistance, high temperature resistance and electrical insulation properties. It is widely used in chemical, electronic, semiconductor and other fields.

[0003] A new type of polyperfluoroethylene propylene resin condensation device is disclosed in the utility model patent with the patent authorization announcement number CN201132823Y, which belongs to the technical field of chemical equipment. An agitator consisting of an agitator rotor, an agitator stator and an agitator shaft is arranged on the barrel of the condensation device. The agitator stator is installed in the barrel, the agitator rotor is located between the agitator stators, and the agitator rotor is connected to the agitator shaft. A support is mounted on the agitator shaft, and a mechanical seal is arranged at each end of the support. The mechanical seal located outside the barrel is mounted on the agitator shaft and connected to the barrel, and the mechanical seal located inside the barrel is connected to the stator seat of the agitator. One end of the agitator shaft located outside the barrel is connected to a pulley of a power transmission device. The agitator form of the utility model has a large contact surface with the material, a good stirring effect, a more uniform mixing of the materials, and a lower final water content, thereby reducing the washing time of the next process, effectively increasing the output, and saving costs.

[0004] However, the existing fluoroethylene propylene resin coagulation device with high reaction rate also has certain shortcomings. First, the existing fluoroethylene propylene resin coagulation device with high reaction rate simply adopts the cooperation of servo motor, transmission belt and other structures to complete the driving of the driving shaft.
