[0015] Figure 1 It is a structural schematic diagram of the present invention.

[0016] In the figure: sealed warehouse 1, exhaust port 2, odor purifier 3, storage bin 4, down pipe 5, fan 6, exhaust pipe 7, air inlet pipe 8, heat exchange fin 9, pipe body 10, exhaust hole 11, heating element 12, screw conveyor 13, discharge port 14. DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1 A masterbatch odor removal device comprises a sealed warehouse 1, the sealed warehouse 1 is provided with an exhaust port 2, an odor purifier 3 connected to the exhaust port 2 is arranged outside the sealed warehouse 1, a plurality of storage bins 4 are arranged in the sealed warehouse 1, a masterbatch circulation device is installed in the storage bins 4, the masterbatch circulation device comprises a pipe body 10, a pneumatic circulation mechanism capable of circulating the masterbatch between the storage bins 4 and the pipe body 10, and a plurality of exhaust holes 11 are opened on the periphery of the pipe body 10.

[0019] When the device is working, the masterbatch in the storage bin 4 is driven to circulate between the storage bin 4 and the tube body 10 through the pneumatic circulation mechanism. When the masterbatch moves in the tube body 10, since the exhaust holes 11 are opened on the sides of the tube body 10, the odor of the masterbatch can be emitted outward through the exhaust holes 11. The device arranges multiple storage bins 4 in the sealed warehouse 1. The masterbatch in the multiple storage bins 4 moves in the tube body 10 at the same time, and emits the odor outward through the exhaust holes 11 of the tube body 10 at the same time. Since the work of emitting the odor is carried out inside the sealed warehouse 1, the odor is uniformly transmitted to the odor purifier 3 through the exhaust port 2 for purification, thereby improving the overall efficiency of odor removal.

[0020] The tube body 10 is arranged vertically, and the pneumatic circulation mechanism includes a fan 6. The exhaust end of the fan 6 is connected to the lower end of the tube body 10 through the exhaust pipe 7. The fan 6 can generate an airflow to push the masterbatch from the lower end of the tube body 10 to the upper end. The upper end of the tube body 10 is connected to the feed port of the storage bin 4, and the lower end of the tube body 10 is connected to the discharge port of the storage bin 4. The masterbatch enters the tube body 10 from the storage bin 4, and is pushed upward by the airflow generated by the fan 6. Finally, the masterbatch flows back to the storage bin 4. In the process of the airflow pushing the masterbatch, part of the airflow carries the odorous gas of the masterbatch and is discharged from the exhaust hole 11 of the tube body, and the pushed airflow is used to further improve the efficiency of odor emission.

[0021] In order to further promote the speed of odor dissipation, a plurality of heating elements 12 are arranged at intervals along the length direction of the tube body 10. The heating elements 12 can heat the internal environment of the tube body 10. The tube body 10 is heated by the heating elements 12, and the heat is used to promote the dissipation of the masterbatch odor.

[0022] As another heating method, a heating device is installed between the exhaust pipe 7 and the lower end of the pipe body 10 , and the heating device can heat the airflow in the exhaust pipe 7 .

[0023] In order to make the masterbatch enter the tube body 10 at a uniform speed and in a uniform amount, the odor removal device includes a screw conveyor 13, the feed port of the screw conveyor 13 is connected to the discharge port of the storage bin 4, and the discharge port 14 of the screw conveyor 13 is connected to the lower end of the tube body 10, and the masterbatch is pushed to the lower end of the tube body 10 by the screw conveyor 13. Of course, in order to avoid static pressure congestion of the masterbatch at the discharge port of the storage bin 4, an additional screw pushing mechanism can also be set at the discharge port of the storage bin 4, as long as the masterbatch in the storage bin 4 can be discharged outward uniformly.

[0024] The use of heating can promote the emission of the masterbatch odor, but the heating will cause the masterbatch to accumulate heat, which will affect the performance of the masterbatch. The feed inlet of the storage bin 4 is connected with a drop pipe 5, and the upper end of the tube body 10 is connected to the upper part of the drop pipe 5 through an inclined tube. The drop pipe 5 is penetrated by an air inlet pipe 8. At least the part of the air inlet pipe 8 located inside the drop pipe 5 is a heat-conducting pipe body. One end of the air inlet pipe 8 is connected to the air inlet end of the fan 6, and the other end of the air inlet pipe 8 is connected to the external environment of the sealed warehouse 1. The device sets a section of drop pipe 5 at the feed inlet of the storage bin 4. The masterbatch discharged by the tube body 10 falls in the drop pipe 5. The drop pipe 5 is penetrated by an air inlet pipe 8. At least the part of the air inlet pipe 8 located inside the drop pipe 5 is a heat-conducting pipe body. The airflow temperature of the external environment of the sealed warehouse 1 will be lower than the temperature of the internal environment. When the external low-temperature airflow passes through the position of the heat-conducting pipe body, it exchanges heat with the heat in the drop pipe 5, so as to achieve the cooling of the ambient airflow when the masterbatch falls, and avoid the problem of heat accumulation.

[0025] The air inlet pipe 8 is a heat-conducting pipe body and is provided with heat exchange fins 9 on the circumference of the part, and the heat exchange fins 9 are used to improve the heat exchange efficiency.
