The speed-regulating motor reducer of the titanium reactor drives the outer magnetic steel body, and the strong magnetic force passes through the sealed cylinder made of stainless steel without contact. The strong magnetic force between the titanium reactor and the inner magnetic steel body sealed in the sealing cover interacts with each other. Attraction and mutual self-positioning act on the axial rotation and traction to carry out high-temperature and high-pressure stirring reactions. The titanium reactor can keep the reaction medium completely in a static sealing state under high temperature, high pressure, high vacuum, high speed, suspension, and convection, and can safely carry out harsh tasks such as flammable, explosive, highly toxic, hydrogen, and hydrofluoric acid. Efficient reaction of media.
