[0002] Polyester polyols, organic substances, are usually formed by the condensation of organic dicarboxylic acids and polyols or by the polymerization of lactones and polyols. The dibasic acids include phthalic acid or phthalic anhydride or its esters, adipic acid, halogenated phthalic acid, etc. The polyols include ethylene glycol, propylene glycol, diethylene glycol, trimethylolpropane, pentaerythritol, etc. Different varieties of polyester polyols have different properties due to different types or preparation processes. The more important indicators for polyester polyols are hydroxyl value, acid value, moisture, viscosity, molecular weight, density and chromaticity. Characteristics and uses of polyester polyols: Polyester polyurethanes contain more polar groups such as ester groups and amino groups in their molecules, have strong cohesive strength and adhesion, and have high strength and wear resistance.

[0003] However, the temperature in the existing reactor is relatively unstable, which may lead to incomplete chemical reaction, and the stirring component does not have a component for reflux and repeatedly stirring the raw materials during the stirring process, which affects the uniformity of the raw material mixing and the reaction efficiency.

[0023] In this embodiment, a slope 11 is fixed on the highest point of the annular ramp 6, and the return pipe 10 is located between the annular ramp 6 and the end of the slope 11, and is located in the insulation chamber 5 with a top opening. The opening can receive the water flowing down from the slope 11 and the annular ramp 6 and flow it into the water tank 7.

[0024] In this embodiment, a water filling port 12 is fixedly provided on the top of the water tank 7 to facilitate water filling in the water tank 7 .

[0025] In this embodiment, a servo motor 13 is fixed to the outer top surface of the reactor 2, and a rotating shaft 14 extending into the control chamber 3 is fixedly provided on the servo motor 13. A driving gear 15 is fixedly connected to the end of the rotating shaft 14. Driven gears 16 are provided on both sides of the driving gear 15. The driven gear 16 is rotatably connected to a fixed block 17 fixed to the top wall of the control chamber 3. The driving gear 15 and the driven gear 16 are respectively fixedly connected with a first connecting rod 18 and a second connecting rod 19 extending into the processing chamber 4. The driving gear 15 can be meshed with the driven gears 16 on both sides when rotating, so that reflux and stirring are carried out simultaneously.

[0026] In this embodiment, a spiral blade 20 is fixed on the first connecting rod 18, and a reflux barrel 21 is fixedly connected to the top wall of the processing chamber 4 at the periphery of the spiral blade 20. An arc-shaped discharge plate 22 is provided on the top of the reflux barrel 21, and a plurality of stirring blades 23 are fixedly connected to the second connecting rod 19.
