1) connecting a first inlet (101) of the cylinder (1) with an external material supply device A, a second inlet (102) of the cylinder (1) with an external material supply device B, and an outlet (103) of the cylinder (1) with an external reaction product storage device;
2) An external material A supply device conveys material A to the interior of the reactor through a first inlet (101); an external material B supply device conveys material B to the interior of the reactor through a second inlet (102); simultaneously, the stirring shaft (2) is rotated, and the radial baffle (201) and the stirring blades (202) on the stirring shaft (2) are driven to rotate by the stirring shaft;
When the material A and the material B are contacted with the fixed baffle plate (201) and the stirring blade (202), the material A and the material B are displaced by the force generated by the rotation of the fixed baffle plate (201) and the stirring blade (202); simultaneously, the material A and the material B are sheared by rotating the fixed baffle plate (201) and the stirring blade (202), so that the components of the material A and the material B slide mutually and the contact surface of the component parts is increased, thereby achieving the aim of mixing;
3) In the process that the external materials are continuously input into the cylinder (1) and stirred, the flow track of the mixed materials is changed through the groove group (104) on the inner wall of the cylinder (1), and the mixed materials are further mixed;
4) Under the action of the stirring shaft (2) and the groove group (104), the mixed materials are fully reacted in the cylinder (1) and then output from the outlet (103).
