A first fixing frame 5 is fixed to the top of the shell 1. A first pipe 6 is fixed through the middle of the first fixing frame 5. The outer side of the upper end of the rotating shaft 2 is rotatably connected to the inner side of the lower end of the first pipe 6 via a sealed bearing. A first channel 7 is formed at the upper end of the rotating shaft 2. A first connecting hole 8 is provided at the bottom of the inner side of the first channel 7. The end of the first connecting hole 8 is connected to the guide cavity 4. A second fixing frame 9 is fixed at the bottom of the housing 1. A second pipe 10 is fixed through the inside of the second fixing frame 9. The inner side of the upper end of the second pipe 10 is rotatably connected to the outer side of the lower end of the rotating shaft 2 through a sealed bearing. A second channel 11 is opened at the lower end of the rotating shaft 2. A second connecting hole 12 is opened at the top of the inner side of the second channel 11. The end of the second connecting hole 12 is connected to the guide cavity 4. A driving mechanism is provided on the rotating shaft 2.

[0024] The drive mechanism includes a motor 13. The motor 13 is fixed to the top of the housing 1. A first gear 14 is fixed to the output end of the top of the motor 13. A second gear 15 meshes with one side of the first gear 14. The inner side of the second gear 15 is fixedly connected to the outer side of the rotating shaft 2. By starting the motor 13, the rotating shaft 2 can be driven to rotate.

[0025] Both the stirring blade 3 and the guide cavity 4 are designed with a spiral structure, which increases the contact area of ​​the material, allowing the material to be heated evenly, improving the quality of material production, accelerating the heating speed of the material, and improving work efficiency.

[0026] The bottom of the housing 1 is provided with support legs, and the support legs are distributed at equal angles about the central axis of the housing 1. The support legs are designed to support the entire device. The top of the housing 1 is provided with an exhaust pipe, which is connected to an external exhaust gas treatment device.

[0029] Working principle: When using this plasticizer decolorizing kettle, firstly, the second pipe 10 is connected to the oil outlet of the heatable oil tank through the oil pump, and the end of the first pipe 6 is connected to the oil inlet of the heatable oil tank. Then, the oil pump is started, and the oil pump draws the heated heat transfer oil into the interior of the guide cavity 4 through the second pipe 10, the second channel 11, and the second connecting hole 12. Then, it flows back into the interior of the oil tank through the first channel 7 and the first pipe 6. Since the stirring blade 3 and the guide cavity 4 are both designed with a spiral structure, the contact area between the heat transfer oil and the material inside the shell 1 is increased, so that the material can be heated evenly. By starting the motor 13, the motor 13 drives the first gear 14, the second gear 15, the rotating shaft 2, the stirring blade 3, and the guide cavity 4 to rotate simultaneously. The stirring blade 3 plays a stirring role on the material inside the shell 1, and when the stirring blade 3 rotates, it can drive the internal heat transfer oil to rotate, which is beneficial for the heat transfer oil to heat the material.
