[0067] The working principle of this embodiment is:

[0068] First, when the reactants slide into the inner side of the feeding barrel 12 through the discharge port 22, the reactants will first slide into the inclined surface between the connection of the first conical plate 17 and the second conical plate 18. When the pressing plate 21 is controlled to drive the connecting rod 20 to move downward and drive the first conical plate 17 to drive the second conical plate 18 to move, the reactants located between the connection of the first conical plate 17 and the second conical plate 18 will be carried downward together (at the same time, the spring 19 is squeezed by force), and then slide out through the gap between the fixed sleeve 16 and the feeding barrel 12 where they are not connected and fall onto the upper end surface of the collecting and cleaning device 11 inside the reactor 1. At the same time, when the first conical plate 17 moves downward, it will also block the reactants inside the feeding barrel 12.

When the fixed plate 27 moves, it will drive the brush plate 28 to move on the inner side of the reactor 1. If solids (for example: 2-fluoro-5-[(4-oxo-3,4-dihydrophthalazin-1-yl)methyl]benzonitrile (compound of formula III) wet product is added with 5% sodium hydroxide (300 mol) for a controlled time and stirred evenly, an appropriate amount of activated carbon is added for decolorization and filtration, the filtrate is cooled to 50°C and extracted twice with an appropriate amount of ethyl acetate, an appropriate amount of acetic acid is added to the water layer, the pH value of the solution is adjusted to 4.0, stirring is continued for 1 hour, filtering, and the filter cake is washed with an appropriate amount of water to obtain an off-white solid) are attached to the inner side of the reactor 1, the brush plate 28 can be moved to brush off the solids that have not been attached while stirring to prevent attachment, and the stirring column 26 can be driven to move by the movement of the brush plate 28 and the rotation of the long column 25, so that the compound can be evenly and fully stirred to improve the synthesis quality;

[0070] Third, when the reaction needs to be cooled after being fully stirred, the second baffle 35 fixedly connected by the connecting column is driven by the moving push plate 5 to rotate and be offset from the first baffle 34, so that the reactants fall onto the heat dissipation aluminum plate 31 through the leak hole 33, and when the long column 25 rotates, the heat dissipation fan 32 is driven to rotate together, and the heat is transferred to the heat dissipation aluminum plate 31 through the contact between the reactants and the heat dissipation aluminum plate 31, and the heat dissipation fan 32 rotates to take away the heat on the heat dissipation aluminum plate 31 through the air flow and blown out from the air vents 36 to achieve cooling;

[0071] Fourthly, the push plate 5 is moved again to close the mutual displacement between the second baffle plate 35 and the first baffle plate 34. While stirring the reactants, the reactants that need to be cooled after stirring can also be cooled synchronously, thereby reducing time consumption and being more convenient to use.

[0072] The utility model provides a reactor device for pharmaceutical and chemical industry through improvement. By controlling the force to press the pressing plate 21, the connecting rod 20 is driven to move downward, the first conical plate 17 is driven to drive the second conical plate 18 to move, and the reactants are driven to move downward together. The outflow of the reactants can also be easily controlled. At the same time, the motor 23 is turned on to drive the short column 24 to drive the fixed plate 27 to move and the long column 25 to rotate. When the fixed plate 27 moves, the brush plate 28 can be driven to quickly brush the inner side of the reactor 1 to prevent solid adhesion during the reaction process. At the same time, the long column 25 is driven to rotate to drive the stirring column 26 to move, and the chemical can be evenly and fully cleaned. The reaction mixture is stirred to improve the synthesis quality. When cooling, the push plate 5 is moved to drive the second baffle 35 fixedly connected by the connecting column to rotate and be displaced with the first baffle 34. The reactant falls onto the heat dissipation aluminum plate 31 through the leak hole 33 and contacts the heat dissipation aluminum plate 31 to transfer heat. When the long column 25 rotates, the heat dissipation fan 32 is driven to rotate together to drive the air flow to take away the heat on the heat dissipation aluminum plate 31 to achieve cooling. At the same time, the push plate 5 is moved to close the mutual dislocation between the second baffle 35 and the first baffle 34. While stirring the reactant, the reactant that needs to be cooled after stirring can also be cooled synchronously, which is more convenient to use.
