The exhaust fan 17 is fixedly installed inside the bottom end of the housing 14. The connecting pipe 10 is fixedly installed on the top of the exhaust pipe 9.

[0027] The top and bottom ends of the cooling coil 13 pass through the interior of the top and bottom ends of the mounting frame 12, respectively.

[0028] Specifically, such as Figures 1-3 As shown, the exhaust gas generated inside the vessel body 3 can be directly discharged outward through the exhaust pipe 9 and the connecting pipe 10. Some of the exhaust gas, which carries heat, enters the interior of the cooling coil 13 and is cooled by the cold wall tubes of the cooling coil 13 arranged in a disc shape. At the same time, the blower 11 is turned on to blow air and dissipate heat from the cooling coil 13, thereby improving the cooling efficiency.

The top of the main stirring shaft 19 passes through the interior of the top of the top cover 4 and the top of the top seat 6. The tops of the two sets of auxiliary stirring shafts 18 pass through the interior of the top of the top cover 4 and are movably connected to the top of the interior of the top seat 6.

[0031] Specifically, such as Figures 1-3 As shown, during the mixing process of the internal materials, the main stirring shaft 19 can be driven to rotate by the drive motor 8 and the reducer 7. While the main stirring shaft 19 is rotating, the two auxiliary stirring shafts 18 can be driven to rotate by the gear 3 25, the two sets of gear 24, and the two sets of gear 1 23, thus achieving efficient mixing at multiple positions.

[0032] A fixing tube 26 is welded and fixed to the rear end of the top of the top cover 4, and a fixing ring 27 is welded and fixed to the top end of the outside of the fixing tube 26.

[0035] Working principle: During the use of this environmentally friendly low-temperature high-efficiency modified reactor for recycled plastics, the drive motor 8 can be started and the main stirring shaft 19 can be driven to rotate by the reducer 7 during the stirring and mixing of the internal materials. The rotation of the main stirring shaft 19 can be driven by the gear 3 25, two sets of gear 24 and two sets of gear 1 23 to drive the two sets of auxiliary stirring shafts 18 to rotate, so as to carry out multi-position high-efficiency stirring. At the same time, during the use of the reactor, an installation ring 21 and a viewing plate 22 are installed on the fixed pipe 26 at the rear end of the top of the top cover 4. The state of the internal materials of the reactor body 3 can be directly inspected from the outside of the reactor through the viewing plate 22.

[0036] Meanwhile, the exhaust gas generated inside the vessel body 3 can be directly discharged outward through the exhaust pipe 9 and the connecting pipe 10. Some of the exhaust gas, which carries heat, enters the interior of the cooling coil 13 and is cooled by the cold wall tubes of the disc-shaped cooling coil 13. At the same time, the blower 11 is turned on to blow air and dissipate heat from the cooling coil 13, thereby improving the cooling efficiency. After cooling, the exhaust gas enters the interior of the casing 14 and is then filtered by two sets of activated carbon filters 16 to remove harmful substances from the exhaust gas and render it harmless.
