[0031] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 An embodiment of this utility model provides a triple preheater with airflow-assisted heating, including a primary preheating chamber 1, a secondary preheating chamber 3 fixedly connected to the left side of the primary preheating chamber 1, a senior preheating chamber 4 fixedly connected to the left side of the secondary preheating chamber 3, an air inlet 5 fixedly connected to the top left front end of the primary preheating chamber 1, a preheating pipe 6 fixedly connected to the rear end of the air inlet 5, multiple heat-conducting plates 7 fixedly connected to the outer wall of the preheating pipe 6, an exhaust port 8 fixedly connected to the bottom right front end of the primary preheating chamber 1, an air guide pipe 9 fixedly connected to the front end of the air inlet 5, a fan 10 fixedly connected to the right end of the primary preheating chamber 1, a flow equalization plate 11 fixedly connected to the right side of the inner wall of the primary preheating chamber 1, and an auxiliary mechanism 2 provided at the rear side of the primary preheating chamber 1. The auxiliary mechanism 2 is used for disassembling and assembling the structure and improving the sealing performance.

[0032] Specifically, the primary preheating chamber 1 is connected to the intermediate preheating chamber 3 and the advanced preheating chamber 4, ensuring continuous heat transfer. The air inlet 5 is responsible for introducing external air into the chamber. The air inlet 5 is connected to the preheating pipe 6, which improves the preheating efficiency of the air through multiple heat-conducting fins 7. An exhaust port 8 is provided on the preheating chamber to discharge the used exhaust gas. In order to guide the airflow, there is a guide pipe 9 at the front end of the air inlet 5 to ensure that the air can enter the preheating chamber smoothly. A fan 10 is connected to the primary preheating chamber 1. The function of the fan 10 is to provide the necessary airflow to ensure the circulation of air in the preheating chamber. In order to make the air evenly distributed in the primary preheating chamber 1, a flow equalization plate 11 is fixedly connected to the right side of its inner wall. It helps to reduce dead zones in airflow and improve preheating efficiency. An auxiliary mechanism 2 is provided at the rear of the primary preheating chamber 1.

[0034] Specifically, the mounting bracket 201 is the foundation of the entire structure. It is integrated with the preheating pipe 6 to ensure the stability of the preheating pipe 6 during operation. The mounting groove 202 allows the mounting bracket 201 to slide flexibly, providing a flexible installation method. The sealing ring 203 prevents unnecessary heat loss during preheating and also prevents external dust and impurities from entering the interior. The sealing plate 204 applies pressure to the sealing ring 203 through the extrusion groove 205 to ensure a sealing effect. The sealing plate 204 connects to the mounting plate 206. These mounting plates 206 not only increase the stability of the structure but also provide additional mounting points for fixing the overall structure. The screws 207 strengthen the connection between the mounting plate 206 and the mounting plate 208, forming a stable multi-layer connection structure.

[0035] Please see the appendix Figure 1A controller 12 is fixedly connected to the top front side of the right end of the primary preheating chamber 1.

The buttons 14 provide the operator with a convenient control interface. The power button 15 allows users to easily turn the power on and off. To ensure the stability of the primary preheating chamber 1, multiple support feet 16 are fixedly connected to its bottom. The bottom of these support feet 16 is also additionally fixedly connected to foot pads 17, which not only increases the contact area with the ground but also effectively protects the ground from damage.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The left end of the advanced preheating chamber 4 is fixedly connected to an air outlet 18, and the left side of the air outlet 18 is fixedly connected to an enlarged diameter port 19. Multiple decorative strips 20 are provided on the front side of the advanced preheating chamber 4, and the multiple decorative strips 20 are arranged at equal intervals. A nameplate 21 is fixedly connected to the top of the front side of the primary preheating chamber 1, and a protective net 22 is fixedly connected to the right side of the fan 10.

[0038] Specifically, the air outlet 18 is located on the left side of the advanced preheating chamber 4 and is connected to an expansion port 19 to widen the airflow channel. The decorative strips 20 are arranged at equal intervals to enhance the aesthetics. A nameplate 21 is fixedly connected to the top front side of the primary preheating chamber 1. This nameplate 21 contains important identification information. There is a protective net 22 on the right side of the fan 10. The purpose of this protective net 22 is to prevent foreign objects from entering the fan 10 and to ensure the safe operation of the equipment.

[0039] Working principle: The system consists of three interconnected zones: a primary preheating chamber 1, an intermediate preheating chamber 3, and a high-level preheating chamber 4. Air inlets 5 connect to the three preheating chambers, allowing high-temperature exhaust gas to enter the preheating pipes 6 connected to the inlets 5. Multiple heat-conducting plates 7 are connected to the preheating pipes 6 to transfer heat from the exhaust gas. The exhaust gas is then discharged through the exhaust port 8 and enters the next stage through the air guide pipe 9 until it is discharged. A fan 10 is installed on the primary preheating chamber 1 to assist air intake. The air first enters the primary preheating chamber 1 and is evenly dispersed by the flow equalization plate 11. It then contacts the heat-conducting plates 7 for heating, then enters the hotter intermediate preheating chamber 3 for further heating, and finally enters the hottest high-level preheating chamber 4 for complete heating. This structure fully utilizes the exhaust gas, saves energy, improves heat conversion efficiency, reduces costs, and meets usage requirements.

[0040] By installing and connecting the mounting bracket 201 on the preheating pipe 6, the structure can be slidably installed on the internal mounting groove 202 of the preheating chamber. A sealing ring 203 is set on the rear side of the preheating chamber. The sealing ring 203 can be squeezed and sealed by mating with the extrusion groove 205 opened on the sealing plate 204. Since the mounting plate 206 is fixed on the sealing plate 204, the screws 207 on the mounting plate 206 are tightened with the threads of the mounting plate 208 on the preheating chamber to complete the sealing installation of the structure. This structure can improve the sealing performance of the equipment, ensure the normal operation of the equipment, and facilitate the disassembly and maintenance of the structure, thus meeting auxiliary needs.
