[0002] An air preheater is a heat exchanger arranged in the tail flue of a boiler. It mainly heats the air before entering the boiler by using the waste heat of flue gas, so as to improve the heat exchange performance of the boiler and reduce energy consumption. It plays a crucial role in the boiler system. By recovering the waste heat of flue gas, improving the combustion efficiency, and strengthening the radiation heat transfer in the furnace, etc., it significantly improves the overall performance and economic benefits of the boiler.

[0003] At present, for some transmission structures of air preheaters in the market, the motors are often fixed in relatively concealed or inaccessible positions. This makes it necessary for maintenance personnel to disassemble a large number of other components when daily maintenance or fault troubleshooting of the motor is required, increasing the complexity and time cost of maintenance. This design is difficult to achieve the quick disassembly and assembly of the motor, making it very inconvenient for users. And some transmission structures are designed compactly, but the operation space left for maintenance personnel is limited, resulting in difficulties in operation or safety hazards easily occurring during the maintenance process. Therefore, a transmission structure for an air preheater is proposed to solve the above problems. Content of the Utility Model

[0026] Please refer to Figures 1-3 , a transmission structure for an air preheater, including a support mechanism and a mounting mechanism, and the mounting mechanism is arranged on the support mechanism.

[0027] In this embodiment, the support mechanism includes a top frame 1. The top frame 1 serves as the main support part of the entire transmission structure, bearing all other components and ensuring the stability and safety of the entire structure. A rotating shaft 2 is rotatably connected in the middle of the top frame 1. The rotating shaft 2 is a key component for transmitting power and rotational motion. It connects the driven gear 4 above and the heat exchange component 11 below, realizing the transmission of power from the driving motor to the heat exchange component. An installation plate 3 is fixedly installed on the top of the top frame 1. The installation plate 3 provides an installation base for the driven gear 4, ensuring that the driven gear can be stably sleeved on the rotating shaft 2. A driven gear 4 is sleeved on the surface of the rotating shaft 2 above the installation plate 3. The driven gear 4 transmits the rotational power of the driving motor to the rotating shaft, and then drives the heat exchange component to work. Baffles 5 are fixedly installed at both the front and rear ends of the top of the top frame 1. The baffles 5 mainly play a protective role, preventing external objects or personnel from accidentally contacting the transmission components, and at the same time preventing the fixing plate 7 from detaching from the slide rail 6, improving the safety of the equipment.

[0028] In this embodiment, a pair of slide rails 6 are arranged on the right side of the top of the top frame 1. The slide rails 6 provide a sliding track for the fixing plate 7, enabling the fixing plate to slide freely along the slide rails, thus facilitating the disassembly, assembly, and maintenance of the driving motor. The fixing plate 7 is slidably connected to the surface of the slide rails 6. The fixing plate 7 serves as a support platform for the driving motor 9 and can move on the slide rails to adjust the position of the driving motor. A support rod 8 is fixedly installed on the top of the fixing plate 7. The support rod 8 provides a stable support for the driving motor 9, ensuring the stability of the motor during operation. The driving motor 9 is fixedly installed on the top of the support rod 8. The driving motor 9 is the power source of the entire transmission structure. Through its rotational motion, it drives the driving gear 10 to rotate, and then drives the driven gear 4 and the rotating shaft 2 to rotate, realizing the transmission of power. The driving gear 10 is sleeved on the surface of the support rod 8.

[0029] In this embodiment, a heat exchange component 11 is fixedly connected to the surface of the rotating shaft 2 below the top frame 1. A limit plate 12 is fixedly installed on the top of the rotating shaft 2. The limit plate 12 plays a limiting role, preventing the driven gear 4 from detaching during rotation and ensuring the stability and reliability of the transmission.

[0030] In this embodiment, fixing blocks 13 are fixedly installed at one ends of the pair of baffles 5 on the right side close to the installation plate 3. Fixing holes are provided on the surfaces of the fixing blocks 13 and the front and rear outer walls of the fixing plate 7. A fixing bolt is inserted through the fixing holes on the surface of the fixing block 13. The fixing blocks 13 and the fixing bolts are used to lock the fixing plate 7 in a specific position to prevent it from sliding in the non-maintenance state.

[0031] In this embodiment, support columns 14 are fixedly installed at both left and right bottom ends of the top frame 1. The support columns 14 provide support for the entire structure, enhancing the stability and load-bearing capacity of the structure. A chute 15 is formed inside the right support column 14. The chute 15 provides an installation space for the electric telescopic rod 16 and the support plate 18, enabling the electric telescopic rod to drive the support plate 18 to move up and down. The opening of the chute 15 on the right support column 14 is provided on its right outer wall.

[0032] In this embodiment, an electric telescopic rod 16 is fixedly installed at the bottom of the inner wall of the chute 15. The electric telescopic rod 16 drives the support plate 18 to move up and down through telescopic movement, thereby adjusting the height positions of the fixing plate 7 and the driving motor 9 slid onto the support plate 18, facilitating disassembly, assembly, and maintenance by maintenance personnel. Guide rails 17 are fixedly installed at both front and rear ends of the inner wall of the chute 15. The guide rails 17 provide a sliding track for the support plate 18, ensuring the stability and accuracy of the support plate 18 during the up and down movement.

[0033] In this embodiment, a support plate 18 is slidably connected to the middle of the guide rail 17. The support plate 18 serves as a lifting platform for the fixing plate 7 and the driving motor 9, and realizes the lifting function through the drive of the electric telescopic rod. The bottom of the support plate 18 is fixedly connected to the electric telescopic rod 16.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
