[0044] Please refer to the attached document. Figures 1-5 This application provides a push-pull damper assembly 100, which is applied to a rotary furnace and is used to adjust the air volume of the passage.

[0045] Please refer to the attached document. Figures 1-5 In the embodiments of this application, the push-pull damper assembly 100 includes a rotary furnace shell 10, a damper 20, and a power component 30; the rotary furnace shell 10 is provided with a vent 10a and an air duct 10b; the vent 10a is opened on the outer side wall of the rotary furnace shell 10 and connects to the external environment; the air inlet ends of the vent 10a and the air duct 10b are arranged opposite to each other and are connected; the damper 20 is movably connected to the rotary furnace shell 10 and is located between the vent 10a and the air duct 10b; the power component 30 is provided with... On the side of the rotary furnace shell 10 facing the damper 20; the fixed end of the power component 30 is connected to the rotary furnace shell 10, and the telescopic end of the power component 30 is connected to the damper 20, driving the damper 20 to push and pull laterally. As the damper 20 is pushed and pulled laterally, the ventilation aperture of the channel between the air inlet 10a and the air inlet end of the air duct 10b is adjusted, thereby controlling the air volume of the channel and avoiding the inability to adjust the air volume in the air duct 10b, thus improving the performance of the push-pull damper assembly 100.

[0046] Please refer to the attached document. Figures 1-3 In the embodiments of this application, the rotary furnace shell 10 serves as a supporting component of the push-pull damper assembly 100, and the rotary furnace shell 10 supports the damper 20 and the power component 30. The rotary furnace shell 10 is provided with a vent 10a and an air duct 10b; the vent 10a is opened on the outer side wall of the rotary furnace shell 10 and connects to the external environment; the vent 10a and the air inlet end of the air duct 10b are arranged opposite to each other and are connected, so that the air from the external environment can flow through the vent 10a to the air inlet end of the air duct 10b, thereby facilitating the transfer of the air from the external environment to the air duct 10b.

[0047] Please refer to the attached document. Figures 1-2 4. In the embodiments of this application, the damper 20 is disposed on the inner side of the rotary furnace shell 10. The damper 20 is movably connected to the rotary furnace shell 10 and is located between the vent 10a and the air duct 10b, so as to adjust the position of the damper 20 relative to the rotary furnace shell 10, thereby facilitating the adjustment of the gap between the vent 10a and the damper 20.

[0048] Please refer to the attached document. Figures 1-25. In the embodiments of this application, the power component 30 is disposed on the side of the rotary furnace shell 10 facing the damper 20; the fixed end of the power component 30 is connected to the rotary furnace shell 10, and the telescopic end of the power component 30 is connected to the damper 20, and drives the damper 20 to be pushed and pulled laterally, so that the damper 20 can move automatically relative to the rotary furnace shell 10 under the action of the power component 30. As the damper 20 is pushed and pulled laterally, the ventilation aperture of the channel between the air inlet 10a and the air inlet end of the air duct 10b is adjusted, thereby controlling the air volume of the channel, avoiding the inability to adjust the air volume in the air duct 10b, and improving the use effect of the push-pull damper assembly 100.

[0049] Please refer to the attached document. Figures 1-2 5. The push-pull damper assembly 100 also includes a linear bearing 40, which is connected to the rotary furnace shell 10 to facilitate fixing the linear bearing 40 to the rotary furnace shell 10. The power component 30 includes a power telescopic component 31 and an extension rod 32; the fixed end of the power telescopic component 31 is connected to the rotary furnace shell 10 to facilitate fixing the power telescopic component 31 to the rotary furnace shell 10, and the telescopic end of the power telescopic component 31 is connected to the extension rod 32 and connected to the damper 20 via the extension rod 32 to extend the distance of the telescopic end of the power telescopic component 31, thereby facilitating the telescopic end of the power telescopic component 31 to drive the damper 20 to move relative to the rotary furnace shell 10 via the extension rod 32. The extension rod 32 is movably threaded through and guided by the linear bearing 40. The linear bearing 40 ensures the smooth movement of the extension rod 32 relative to the rotary furnace shell 10. The two ends of the extension rod 32 are respectively connected to the telescopic end of the power telescopic component 31 and the damper 20, so that the damper 20 can move relative to the rotary furnace shell 10. As the damper 20 moves, the ventilation aperture of the channel between the air inlet 10a and the air inlet end of the air duct 10b is adjusted, thereby controlling the air volume of the channel. This avoids the inability to adjust the air volume in the air duct 10b and improves the performance of the push-pull damper assembly 100.

[0050] Please refer to the attached document. Figures 1-3 The rotary furnace shell 10 is connected to two guide rail arms 11, which are arranged opposite each other in the vertical direction to form a guide rail groove 11a. The damper 20 passes through the two guide rail arms 11 and is pushed and pulled laterally under the guidance of the guide rail groove 11a. This allows the damper 20 to move relative to the rotary furnace shell 10 under the guidance of the guide rail groove 11a, improving the smoothness of the lateral pushing and pulling of the damper 20 relative to the rotary furnace shell 10, ensuring the pushing and pulling direction of the damper 20, and preventing the damper 20 from deviating from the ventilation opening 10a.

[0051] Please refer to the attached document. Figures 1-3The rotary furnace shell 10 is provided with a shell part 12 and a cover part 13, which are connected to each other. The shell part 12 is provided with a vent 10a. The cover part 13 is provided with an air inlet end of an air duct 10b. The vent 10a and the air inlet end of the air duct 10b are arranged opposite to each other and connected. The power component 30 is located on the outside of the cover part 13, and the damper 20 is located on the inside of the cover part 13, so that the damper 20 is located between the vent 10a and the air inlet end of the air duct 10b. The power telescopic component 31 and the damper 20 are separated by the cover part 13. The extension rod 32 passes through the cover part 13 so that the power telescopic component 31 and the damper 20 can be connected through the extension rod 32, so that the power telescopic component 31 can drive the damper 20 to move through the extension rod 32. As the damper 20 moves, the ventilation aperture of the channel between the vent 10a and the air inlet of the duct 10b is adjusted, thereby controlling the air volume of the channel and avoiding the inability to adjust the air volume in the duct 10b, thus improving the performance of the push-pull damper assembly 100.

[0052] Please refer to the attached document. Figures 1-2 4. The damper 20 is provided with multiple through holes 20a, which are arranged at intervals. As the damper 20 is pushed or pulled, the through holes 20a connect the vent 10a and the duct 10b in different directions, and adjust the ventilation aperture of the channel between the air inlet of the vent 10a and the air inlet of the duct 10b. This allows for adjustment of the gap between the multiple through holes 20a and the vent 10a, thereby controlling the airflow of the channel. A larger gap between the multiple through holes 20a and the vent 10a results in a larger airflow, and a smaller gap results in a smaller airflow. Optionally, the through holes 20a can be square, irregularly shaped, or arc-shaped, while the vent 10a can be square, to ensure compatibility between the through holes 20a and the vent 10a.

[0053] Please refer to the attached document. Figures 1-3 The air inlet of the air duct 10b is annular and is arranged relative to the center of the vent 10a so that the air duct 10b can be adapted to the outer contour of the external air suction component, thereby facilitating the inner wall of the air duct 10b to accommodate part of the external air suction component.

[0054] Please refer to the attached document. Figures 1-3 The rotary furnace shell 10 is also connected to a filter plate 14, which is arranged relative to the vent 10a and filters some external objects so as to prevent external objects from entering the air duct 10b, thus ensuring the cleanliness of the air in the air duct 10b.

[0055] In another embodiment, a rotary oven includes a push-pull damper assembly 100, which is part of the rotary oven. The push-pull damper assembly 100 adjusts the air volume of the rotary oven. A rotary oven is a device that uses a variety of different energy sources to heat the combustion chamber and sends hot air into the furnace through a heat exchanger and a fan to bake the items inside the furnace.
