There are two cover plates 13, which are rotationally arranged on the upper part of the heating cavity of the inner liner 12 by means of threads and are in contact with the sealing ring on the upper part of the heating cavity of the inner liner 12 to achieve sealing and avoid the overflow of gas during the reaction process. The heating device 14 is composed of a constant temperature heater and a heating tube, which is arranged on the bottom wall of the pot body 11. The temperature sensing device 15 is a dry-burning prevention sensor, which is arranged on the bottom wall of the pot body 11. During the research and development of monodisperse polystyrene microspheres, the raw material solvents, monomer concentrations, initiators, etc. used for preparing monodisperse polystyrene microspheres are heated in the inner liner 12. The heating device 14 provides constant temperature heating conditions, and the temperature sensing device 15 prevents the solution in the inner liner 12 from dry-burning and reads the real-time temperature. This is the prior art and will not be elaborated here;

[0023] A stirring mechanism 2 is arranged on the pot body 11, and a rotating mechanism 3 is arranged on the stirring mechanism 2. By arranging the stirring mechanism 2 and the rotating mechanism 3 on the pot body 11, the stirring mechanism 2 can stir the raw materials in the two hole cavities of the inner liner 12, improve the reaction effect and reaction speed of the raw materials, and the rotating mechanism 3 can make the stirring mechanism 2 revolve in a circle, so that the stirring mechanism 2 corresponds to the two hole cavities of the inner liner 12 respectively, and at the same time, the stirring mechanism 2 can be staggered with the inner liner 12 for convenient operation;

[0024] The stirring mechanism 2 includes an equipment rack 21, which is detachably installed on the pot body 11. At the other end of the equipment rack 21, two mounting bolts 22 are threadedly assembled. Two threaded holes 23 are opened on the upper end surface of the pot body 11. One end of the mounting bolt 22 is threadedly and rotatably connected to the inner wall of the threaded hole 23. By providing the mounting bolt 22 and the threaded hole 23, the equipment rack 21 can be installed and disassembled, so that the stirring mechanism 2 is fixed on the pot body 11 or the stirring mechanism 2 is disassembled from the pot body 11, improving flexibility. One end of the equipment rack 21 is provided with a connecting frame 24. One end of the connecting frame 24 is fixedly installed with an electric push rod 25. The piston end of the electric push rod 25 is fixedly installed with an equipment sleeve 26. A number of uniformly distributed heat dissipation grooves 261 are opened on the upper end surface of the equipment sleeve 26. A first motor 27 is fixedly arranged on the inner wall of the equipment sleeve 26. The fixed end of the first motor 27 is fixedly installed with a fixing block 271, and the fixing block 271 is fixedly installed on the inner wall of the equipment sleeve 26. The driving output end of the first motor 27 is fixedly installed with a stirring shaft 28. Stirring blades 29 are fixedly installed on the stirring shaft 28. By turning on the first motor 27, the driving shaft of the first motor 27 rotates the stirring shaft 28, and the stirring shaft 28 rotates the stirring blades 29. The stirring blades 29 can stir the raw materials in the two cavities of the inner tank 12. By turning on the electric push rod 25, the piston end of the electric push rod 25 can make the stirring shaft 28 and the stirring blades 29 rise or fall, so that the stirring shaft 28 and the stirring blades 29 can enter or separate from the cavity of the inner tank 12.

[0025] The rotating mechanism 3 includes a rotating shaft 31, which is rotatably installed at one end of the equipment rack 21. One end of the rotating shaft 31 is fixedly connected to the end of the connecting frame 24 away from the electric push rod 25. By driving the rotating shaft 31 to rotate, the rotating shaft 31 can make the connecting frame 24 revolve circumferentially. The connecting frame 24 can make the stirring shaft 28 and the stirring blades 29 revolve circumferentially synchronously through the electric push rod 25, the equipment sleeve 26 and the first motor 27. One end of the equipment rack 21 is fixedly provided with a second motor 32. The driving output end of the second motor 32 is fixedly installed with a rotating rod 34.

[0027] Before the constant-temperature heating, the R & D personnel turn on the second motor 32. The drive shaft of the second motor 32 rotates the rotating rod 34. The rotating rod 34 rotates the rotating shaft 31 through two bevel gears 35. The rotating shaft 31 makes the connecting frame 24 revolve circumferentially. The connecting frame 24 makes the stirring shaft 28 and the stirring blades 29 revolve circumferentially synchronously through the electric push rod 25, the equipment sleeve 26 and the first motor 27, so that the stirring shaft 28 and the stirring blades 29 are vertically corresponding to one of the cavities in the inner tank 12.

[0028] Then turn on the electric push rod 25. The piston end of the electric push rod 25 lowers the stirring shaft 28 and the stirring blades 29, so that the stirring shaft 28 and the stirring blades 29 enter a cavity in the inner tank 12 and contact the raw materials. Then turn on the first motor 27. The drive shaft of the first motor 27 rotates the stirring blades 29 through the stirring shaft 28. The stirring blades 29 stir the raw materials in a cavity of the inner tank 12 to mix the raw materials evenly.
