[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-4 This application will be described in detail with reference to the embodiments.

[0022] like Figure 1 As shown, a loosening device for a decarbonization machine includes a Roots blower 1, a heat exchanger 3, and a pressure air column 6. The heat exchanger 3 is equipped with a cold air pipe 2 and a hot air pipe 4. The cold air pipe 2 is connected to the air outlet of the Roots blower 1, and the hot air pipe 4 is connected to a connecting pipe device 5. The pressure air column 6 is arranged vertically in a linear fashion and is connected to the connecting pipe device 5. Horizontally arranged loosening rods 7 are vertically connected to the pressure air column 6. The loosening rods 7 are arranged parallel to each other. Vertically arranged support plates 8 are fixedly connected to the loosening rods 7. The support plates 8 are distributed in a linear array. The support plates 8 can improve the overall strength of the loosening rods 7 and prevent the loosening rods 7 from deforming.

[0023] like Figure 2 As shown, the connecting pipe device 5 includes a connecting main pipe 501, an air inlet pipe 502 on the connecting main pipe 501, the air inlet pipe 502 being connected to the hot air pipe 4, and evenly distributed gas supply branch pipes 503 on the connecting main pipe 501. A pressure chamber 601 is opened inside the pressure gas pipe column 6, and a pressurizing air hole 603 is provided at the upper end of the pressure chamber 601, which is connected to the gas supply branch pipe 503. A through hole 602 is opened at the lower end of the pressure chamber 601.

[0024] like Figure 3 , Figure 4As shown, the loosening bar 7 has an air blowing channel 701 that runs outward from one end along the same central axis. The air blowing channel 701 is connected to the through hole 602. There are two rows of evenly distributed linearly distributed air blowing holes 702 on the upper part of the air blowing channel 701. The openings of the air blowing holes 702 are set obliquely downward.

[0025] The working process of this utility model is as follows: The loosening rod 7 and the support plate 8 are set in the feeding structure of the pelletizing machine cylindrical process equipment. When the feeding structure of the pelletizing machine cylindrical process equipment is working, the mixed raw materials will pass through the loosening rod 7. The Roots blower 1 is started. The Roots blower 1 provides airflow to the heat exchanger 3 through the cold air pipe 2. After the airflow is heated by the heat exchanger 3, the high-temperature hot air enters the connecting main pipe 501 through the hot air pipe 4 and the air inlet pipe 502. The connecting main pipe 501 adds the high-temperature hot air into the pressure chamber 601 through the air supply branch pipe 503. Then, it enters the blowing channel 701 of the loosening rod 7 through the through hole 602. Finally, it is blown out obliquely downward from the blowing hole 702 to disperse the raw materials that have passed through the loosening rod 7. A high-temperature airflow is added to the raw materials to improve the air permeability of the raw material layer.

[0026] By appropriately adjusting the density of the loosening rod 7, the disturbance of the loosening rod 7 to the distribution of the mixed raw materials can be reduced.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
