[0029] Embodiment: In the first step, the cap bolts of the four reaction chamber cover inlets are opened, the inlet caps are opened, and the reactants required for the reaction are poured in. After the equipment is completed, the reaction chamber cover inlet is closed, the drive motor is opened, and the equipment is started. The drive motor drives the first drive wheel to rotate. The first drive wheel and the second drive wheel are connected by a rotating belt. Under the transmission connection of the rotating belt, the second drive wheel starts to rotate, and the driving gear fixedly connected to the second drive wheel rotates under the rotation of the second drive wheel. The rotating belt movably sleeved on the driving gear starts to move. Under the driving action of the rotating belt, the driven gear rotates, and the driven gear is fixedly connected to the rotating main rod. The rotating main rod rotates under the drive of the driven gear. The rotating main rod is fixedly connected to the connecting plate. The rotating plate rotates under the action of the rotating main rod, and the primary agitator fixedly connected to the bottom of the connecting plate starts to rotate, and the reactants inside the reaction chamber are fully mixed horizontally. The first residue scraper and the second residue scraper scrape the inner wall of the reaction chamber to prevent the reactants from sticking to the inner wall, resulting in insufficient reaction of the reactants and reactant residues.

[0030] In the second step, in the previous step, the worker can adjust the temperature by filling the reaction chamber jacket with steam. The reaction chamber jacket is filled with steam through the steam inlet fixedly connected to the outer wall of the reaction chamber jacket. The steam reaction chamber jacket is composed of two layers of metal inside and outside. The two layers of metal form a hollow cavity for gas circulation. The filled steam circulates in the entire cavity to achieve the effect of heating or cooling the reaction chamber. When the reactants are difficult to mix, the worker can turn on the motor connected to the stirring rod active bevel gear. After turning it on, the stirring rod active bevel gear starts to rotate, and the stirring rod driven bevel gear meshing with the stirring rod active bevel gear The stirring rod fixedly connected with the driven bevel gear of the stirring rod starts to rotate, and four stirring device gear sets are fixedly connected to the stirring rod.

The product of the reaction completed in the reactor is discharged through the discharge port at the bottom of the reaction bin, and the waste gas generated in the reaction is discharged through the waste gas outlet. When the discharged waste gas is toxic, the worker can connect an external purification device to the waste gas outlet and discharge it after purification. When the flusulfuron original drug pharmaceutical equipment needs to be cleaned, the worker can repeat the above steps one and two, add clean water or special cleaning liquid to the reaction bin, stir the clean water or special cleaning liquid through the longitudinal stirring device and the transverse stirring device, drive the water flow in the reaction bin, and at the same time, the first residue scraper and the second residue scraper scrape the bin wall multiple times to ensure that there is no residue on the bin wall.

[0032] In the fourth step, after the cleaning action in the previous step is completed, the worker starts the motor connected to the rotating main rod bevel gear again to drive the stirring rod to move. The propulsion stirring paddle, paddle stirring paddle and turbine stirring paddle on the stirring rod rotate. At this time, the reactants in the reaction chamber, the three stirring paddles drive the airflow in the reaction chamber to rotate, and the reaction chamber is air-dried.
