Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-4 The present invention provides the following technical solution:

[0032] A forced-air-supply external mixing burner includes:

[0033] Mounting base 1;

[0034] External burner connector 2 is fixedly connected to the lower end of mounting base 1;

[0035] Outer sleeve 5 is fixedly connected to the upper end of mounting base 1; first ventilation hole 6 is opened on the circumferential surface of outer sleeve 5;

[0036] Inner sleeve 7 is rotatably connected to the inner circumferential wall of outer sleeve 5, and a second ventilation hole 8 is provided on the circumferential surface of inner sleeve 7.

[0037] Disc 13 is fixedly connected to the upper end of outer casing 5; fire distribution mesh 14 is fixedly connected to the upper end of disc 13.

[0038] In a specific embodiment of this utility model, the mounting base 1 provides basic support for the overall structure and serves as a mounting platform for other components, ensuring the overall stability and reliability of the burner. The external burner connector 2 connects to an external burner, guiding fuel or air into the burner to ensure smooth combustion. The outer sleeve 5 is the main outer shell structure of the burner, housing and protecting internal components. It also introduces and distributes air through the first ventilation hole 6 on its circumferential surface, promoting improved combustion efficiency. The first ventilation hole 6 introduces external air into the burner, optimizing air supply during combustion, thereby improving combustion efficiency and reducing pollutant emissions. The inner sleeve 7 adjusts the position and angle of the second ventilation hole 8 through its rotation function, controlling airflow and direction for precise control of the combustion process. The second ventilation hole 8 further refines the air distribution and flow path, ensuring thorough mixing of air and fuel, improving combustion uniformity and stability. The disc 13 supports the flame distribution mesh 14 and also distributes gas, making the combustion process more uniform and preventing localized overheating or incomplete combustion. The flame distribution net 14 disperses the flame into multiple smaller flames through its mesh structure, increasing the combustion area, improving combustion efficiency, and effectively reducing flame temperature and the generation of harmful substances such as nitrogen oxides.

[0039] Please refer to the details. Figure 1-4 The mounting base 1 has a mounting groove 10 on its side end. A cylinder 11 is rotatably connected in the mounting groove 10. A second bevel gear 12 is fixedly connected to one side end of the cylinder 11. A first bevel gear 9 is fixedly connected to the lower end of the inner sleeve 7. The first bevel gear 9 and the second bevel gear 12 mesh with each other.

[0040] In this embodiment, the mounting slot 10 provides a specific space for accommodating and positioning the cylinder 11, allowing it to rotate freely within it. This design ensures that the cylinder 11 can rotate smoothly and precisely, thereby achieving effective control over related components. As a key component for manual or automatic operation, the cylinder 11 allows users to adjust the position or state of certain components inside the burner by rotation. Its design makes operation more convenient, helps improve combustion efficiency or change flame characteristics, and meets different usage needs. The second bevel gear 12, through meshing with the first bevel gear 9, realizes the conversion of force direction, transforming the rotational motion of the cylinder 11 into the rotational action of the inner sleeve 7. This mechanism provides users with a simple and effective way to adjust the position of the inner sleeve 7, thereby controlling the airflow pattern and optimizing the combustion process. The first bevel gear 9 and the second bevel gear 12 cooperate to transmit the rotational power of the cylinder 11 to the inner sleeve 7. This design enables effective mechanical transmission even in a compact space, ensuring that the inner sleeve 7 can be adjusted in angle or position as needed to achieve optimal combustion results.

[0041] Please refer to the details. Figure 1-4 The upper end of the disc 13 is connected to a side frame 15 by bolts and threads, and the side end of the side frame 15 is rotatably connected to a placement rack 16 by a rotating shaft.

[0042] In this embodiment, the disc 13 is connected to the side frame 15 via bolts. This design allows the side frame 15 to be securely mounted on the disc 13 while facilitating disassembly and adjustment. The bolted connection not only enhances structural stability but also provides flexible installation and maintenance options, allowing users to quickly replace or adjust the device according to their needs. The side frame 15 is rotatably connected to the placement rack 16 via a pivot, allowing the placement rack 16 to rotate freely or adjust its angle within a certain range. In this way, users can flexibly adjust the position of the placement rack 16 according to combustion requirements or operational convenience, thereby optimizing flame distribution or adapting to different working environments.

[0043] Please refer to the details. Figure 1-4 The side end of the placement rack 16 is fixedly connected to a first handle 17, and the other side end of the cylinder 11 is fixedly connected to a second handle 18.

[0044] In this embodiment: the first handle 17 is fixed to the side of the mounting rack 16, providing the user with an intuitive and convenient operating interface. By operating the first handle 17, the user can easily adjust the position or state of the mounting rack 16, facilitating equipment maintenance, inspection, or adjustment of combustion parameters. Its design takes ergonomics into account, making the operation process more comfortable and efficient. The second handle 18 is fixed to the other side of the cylinder 11, providing the user with a way to directly control the rotation of the cylinder 11. By rotating the second handle 18, the user can precisely adjust the angle or position of the inner sleeve 7, thereby achieving fine control of the airflow pattern to optimize combustion efficiency or change flame characteristics. This manual adjustment mechanism is simple and easy to use, while ensuring operational accuracy and immediate feedback.

[0045] Please refer to the details. Figure 1-4 A connecting plate 3 is sleeved and connected to the lower end of the mounting base 1, and a bracket 4 is fixedly connected to the lower end of the connecting plate 3.

[0046] In this embodiment: the connecting plate 3 is located at the lower end of the mounting base 1. Its main function is to provide an extended mounting platform, allowing the burner to be installed more securely in the required position. Furthermore, the connecting plate 3 can also be used to adjust the installation angle or position of the burner to adapt to different installation environments and needs. This ensures that the equipment is installed securely and correctly, avoiding operational problems or safety hazards caused by improper installation. The bracket 4 is fixed to the lower end of the connecting plate 3, providing additional support and stability for the entire burner system. The design of the bracket 4 takes into account the needs of different applications, effectively distributing the weight of the equipment, reducing pressure on the mounting point, and ensuring the equipment is in the optimal working posture. This design is particularly suitable for applications requiring long-term stable operation, helping to reduce the impact of vibration on the combustion process and improving the overall system reliability and safety.

[0047] Please refer to the details. Figure 1-4 The inner diameters of the external burner connector 2 and the inner sleeve 7 are equal.

[0048] In this embodiment, the inner diameters of the external burner connector 2 and the inner sleeve 7 are equal, primarily to ensure a smooth and unobstructed transition of gas or fuel as it enters the burner and flows towards the combustion zone. This design helps reduce turbulence and pressure loss, thereby improving combustion efficiency. Specifically, it achieves the following optimizations: by making their inner diameters identical, fluid disturbances caused by sudden changes in cross-section can be avoided, resulting in a more stable airflow, which is beneficial for uniform mixing of fuel and air and efficient combustion.

[0049] The working principle and usage process of this utility model are as follows: First, select a suitable installation location according to actual needs, and securely install the entire device using the bracket 4 and connecting plate 3, ensuring that the location is convenient for operation and maintenance. Connect the fuel source and air supply: correctly connect the external burner connector 2 to the fuel supply system, and ensure that the first ventilation hole 6 and the second ventilation hole 8 can smoothly introduce the required amount of air. By rotating the second handle 18, adjust the position of the cylinder 11, and then adjust the angle or position of the inner sleeve 7 to optimize the airflow pattern. If necessary, the position of the placement rack 16 can be adjusted using the first handle 17 to better control the flame distribution or perform maintenance checks. Turn on the fuel supply and distribute the fuel evenly through the flame distribution net 14. Dissipate the flame and simultaneously turn on the gas supply system, allowing air to enter the burner through the first ventilation hole 6 and the second ventilation hole 8 to ensure that the fuel and air are fully mixed. During combustion, continuously monitor the flame status and combustion efficiency. If necessary, the position of the inner sleeve 7 can be finely adjusted by adjusting the cylinder 11 to adjust the combustion parameters. Regularly check the working status of each component to ensure that no abnormalities occur. First, turn off the fuel source. After the flame is completely extinguished, continue to run the gas supply system for a period of time to help cool the equipment and remove residual fuel gas. Ensure that all energy supplies have been safely cut off. Regularly clean and maintain the equipment, especially cleaning the flame distribution mesh 14, checking the wear of the mounting base 1 and its related components, and replacing damaged parts in a timely manner.
