Adopting end face rare earth coupling driver, it has the characteristics of static sealing and no leakage. The main material for the kettle body is 1Cr18Ni9Ti stainless steel, which can be made according to different medium requirements304, 321316L、 2520Stainless steel, titanium (TA2), nickel, tantalum, zirconium, HastelloyMonelInner lining made of special materials such as polytetrafluoroethylene. The stirring bearing adopts corrosion-resistant stainless steel bearing, suitable for high-speed, hydrogenation catalysis, and low viscosity material stirring. The stirring blade adopts a push type stirring slurry. The heating method is generally dry electric heating, but electric heating, thermal oil heating or jacket heating can also be made according to user requirements. Equipped with a multifunctional temperature control and pressure control digital display control box. The heating control system adopts PID automatic temperature control instrument, and the temperature control is very precise. After tuning, the instrument can effectively suppress temperature overshoot.
