A water tank cooling fan 12 is provided on one side of the water tank 9. The utility model provides a positioning bracket inside the outer shell for fixedly connecting the inner tank. A stirring impeller is provided inside the inner tank. The stirring impeller consists of three parts: an impeller, a rotating shaft and a sealing ring, and cooperates with a water pump, a six-way pipe, a motor and an annular cooling pipe, so that the stirring impeller can realize cooling and stirring simultaneously, improves the mixing uniformity of raw materials, shortens the production cycle, reduces energy consumption, and avoids insufficient cooling of raw materials in the center of the stirring bin, resulting in uneven cooling inside.

[0024] Furthermore, the stirring impeller 5 includes an impeller 501, which is fixedly connected to a rotating shaft 502. A sealing ring 503 is provided on the outer side of the rotating shaft 502 near the inside of the inner tank 4. The sealing ring 503 is rotatably connected to the inner tank 4.

It also ensures that the cooling water can evenly and continuously cover the entire stirring area, thereby further improving the cooling effect.

[0029] Furthermore, the six-way pipe 10 includes a base 1001, a water inlet is provided at the bottom of the base 1001, the base 1001 is internally rotatably connected to a rotating block 1002, four water outlets are provided on the top of the rotating block 1002, the four water outlets are fixedly connected to the water inlet end of the lower cooling channel 508, a positioning plate 1003 is provided on the top of the rotating block 1002, a water pump is fixedly connected to one end of the six-way pipe, and the rotating block can rotate with the stirring impeller, ensuring that the cooling water can accurately enter the lower cooling channel, providing a stable and reliable water source for cooling the stirring impeller.

[0030] Furthermore, the water outlet pipe 510 includes a rotating base 512, and the rotating base 512 is slidably connected to one end of a water outlet branch pipe 513, and the other end of the water outlet branch pipe 513 is fixedly connected to the water tank 9 to ensure the stability of the cooling water circulation.

[0031] In this scheme, the working process is: first, the operator opens the top cover, adds the raw materials for producing PVC heat stabilizer into the inner tank, and then closes the top cover.

[0032] The motor starts and drives the rotating shaft of the stirring impeller to rotate through the output gear, thereby driving the upper impeller and the lower impeller to stir the raw materials.

[0033] At the same time, the water pump starts working, draws cooling water from the water tank and distributes it to the lower cooling channel of the mixing impeller through the six-way pipe.

[0034] After passing through the lower cooling channel, the cooling water enters the upper cooling channel of the upper impeller through the connecting pipe to further cool the raw materials.

[0035] After cooling, the water flows back to the water tank through the water outlet pipe inside the rotating shaft, realizing the recycling of cooling water.

[0036] The annular cooling pipe is fixed on the outside of the inner tank, with its water inlet end connected to the inclined water outlet end of the six-way pipe, and the water outlet end connected to the return water tank, forming an external cooling water circulation system, which helps to reduce the temperature of the inner tank.
