The left ends of the several No. 2 water inlet pipes 8 are connected to the No. 3 water inlet pipe 9. The No. 3 water inlet pipe 9 has an "L" shaped structure, and the inlet of the No. 3 water inlet pipe 9 is located at the lower left. The number of No. 2 water outlet pipes 10 is several, and they are respectively installed on the right side of the annular wall of the jacket 2. The left ends of the several No. 2 water outlet pipes 10 are connected to the No. 3 water outlet pipe 11. The No. 3 water outlet pipe 11 has an "L" shaped structure, and the outlet of the No. 3 water outlet pipe 11 is located at the upper right. Stirring mechanism 12, wherein the stirring mechanism 12 is disposed on the cover; the stirring mechanism 12 comprises: The stirring motor 12-1 is fixed to the cover by a bracket. The stirring motor 12-1 is connected to an external power source. The specific model of the stirring motor 12-1 is purchased and installed directly from the market according to the actual usage requirements. The rotating shaft 12-2 is connected to the output shaft of the stirring motor 12-1, and the rotating shaft 12-2 passes through the cover body; Two bottom rods 12-3 are provided, and each bottom rod 12-3 is fixedly connected to the bottom of the rotating shaft 12-2. The bottom rods 12-3 are fitted to the bottom of the inner wall of the reactor 1. There are two scraper rods 12-4, which are respectively connected to the outer end of the bottom rod 12-3. The scraper rods 12-4 are fitted to the inner ring wall of the reactor 1. Several stirring blades 12-5 are connected between the scraper rods 12-4 and the rotating shaft 12-2. The stirring blades 12-5 are inclined from high to low from the outside to the inside. The serpentine coil 13 is located inside the cover body, and the inlet and outlet of the serpentine coil 13 are inserted into the cover body. The serpentine coil 13 is connected to an external water source. Several downward heat dissipation fins 14 are inserted and fixed on the annular wall of the serpentine coil 13, and two adjacent heat dissipation fins 14 are respectively inclined outward relative to each other. Example 2:

[0019] Please see Figure 1-2 Based on Example 1, the diameter of the first water inlet pipe 6 is set to be smaller than the diameter of the first water outlet pipe 7, and the diameter of the second water inlet pipe 8 is set to be smaller than the diameter of the second water outlet pipe 10.

[0020] When using this utility model, feed is introduced through the feed inlet 3, and the reaction vessel 1 is heated to carry out the reaction; Start the stirring motor 12-1 to make the rotating shaft 12-2 rotate, which drives the bottom rod 12-3 and scraper 12-4 to rotate, stirring the inside of the reaction vessel 1.

The stirring blade 12-5 makes the reactants stir and heat evenly. When cooling is required, water is drawn from the No. 1 inlet pipe 6 and water is discharged from the No. 1 outlet pipe 7, so that an immersed basin-shaped water supply tank is formed at the bottom of the reactor 1, which solves the problem of insufficient cooling due to the large amount of heat released at the bottom during the polymerization process. Water is introduced in sections through No. 3 inlet pipe 9 and No. 2 inlet pipe 8, and water is discharged in sections through No. 2 outlet pipe 10 and No. 3 outlet pipe 11. This allows for uniform cooling inside the jacket 2, stabilizing the pressure in the upper, middle and lower parts of the jacket 2 at the same level, resulting in more uniform heat dissipation and solving the risk of explosive polymerization caused by uneven heat distribution inside the reactor during latex reaction. Introducing cold water into the serpentine coil 13 to cool the upper part of the reactor 1 is beneficial for the ring-shaped cooling of the temperature during the polymerization of gaseous monomers, making the gaseous monomer reaction more complete.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the bottom rod 12-3 and the scraper 12-4 and making them rotate close to the inner wall of the reactor 1, the material sticking is effectively avoided and the reaction uniformity is improved; 2. An immersion basin-shaped water supply tank is formed at the bottom of the reactor 1 by using the No. 1 water inlet pipe 6 and the No. 1 water outlet pipe 7 to enhance the bottom cooling capacity and solve the problem of concentrated heat release. 3. The jacket 2 is equipped with segmented water inlet and outlet through the No. 2 water inlet pipe 8, the No. 3 water inlet pipe 9, the No. 2 water outlet pipe 10, and the No. 3 water outlet pipe 11, so that the pressure inside the jacket 2 is stable and the heat dissipation is uniform, reducing the risk of explosive accumulation. 4. The serpentine coil 13 structure allows for the introduction of cold water to circulate and cool the upper part of the reactor 1, promoting the full reaction of gaseous monomers.
