Description

Technical Field

[0001] This utility model relates to the field of burners, specifically to an easy-to-install burner windbox fixing structure. Background Technology

[0002] In industrial production, the burner, as the core equipment for fuel combustion, needs to work with the bellows to supply air. The installation efficiency and connection stability of the bellows directly affect the equipment assembly progress and operational safety. As industrial production demands increasing equipment assembly efficiency and ease of maintenance, the limitations of traditional fixed structures in terms of installation time and operational complexity are becoming increasingly apparent. Therefore, a fixed structure that can achieve rapid docking, simplify operation, and ensure a stable connection is needed to meet the demands of modern production for efficient assembly and stable operation.

[0003] Traditional burner windbox fixing structures rely on bolt assemblies or welding for connection. During installation, each bolt must be tightened individually or welding work must be performed. This not only requires multiple people or specialized tools, but also necessitates repeated calibration of the docking positions, resulting in long assembly times and severely impacting the equipment installation progress. On the other hand, bolted connections are prone to loosening under long-term vibration, while welded connections are difficult to disassemble and maintain. Furthermore, traditional windboxes often use a straight-through air duct design, which can lead to uneven airflow distribution and incomplete fuel combustion, reducing combustion efficiency and potentially causing safety hazards due to loose connections. This fails to meet the requirements of industrial production for high efficiency, stability, and ease of maintenance. Therefore, we propose an easy-to-install burner windbox fixing structure.

[0019] Compared with the prior art, this utility model provides an easy-to-install burner bellows fixing structure, which has the following advantages:

[0020] 1. This easy-to-install burner air box fixing structure achieves efficient docking through a quick connection mechanism: after the air box docking block and the burner docking groove are coaxially sleeved to complete the initial positioning, the fixing plate is pulled to slide along the square holes of limit block one and limit block two. The sliding block is locked into the locking groove of the fixing plate under the action of the spring. There is no need for cumbersome bolt tightening steps. One person can quickly complete the installation, which greatly shortens the assembly time.

[0021] 2. The easy-to-install burner airbox fixing structure ensures stability through a dual structure: after the quick connection mechanism achieves initial fixation through the rigid engagement of the sliding block and the snap-fit ​​groove, the connection stabilizing mechanism can be further strengthened. Turning the handle drives the screw to push the sliding seat, and through the linkage of the turntable and the connecting rod, the three sliding seats are tightened synchronously. The rubber block fits tightly against the connection between the burner and the airbox, which can not only eliminate assembly gaps, but also buffer vibration and adapt to the stable operation requirements under different working conditions.

[0022] 3. The easy-to-install burner air box fixing structure features a spiral air duct design inside the air box that guides the airflow to form a vortex, making the air and fuel mix more evenly and thus improving combustion efficiency. The straight-through air duct of traditional air boxes can easily lead to uneven airflow distribution, affecting the combustion effect. Attached Figure Description

[0038] Furthermore, the connecting and stabilizing mechanism includes a screw 3, a handle 4, and a support base 5.

It provides the installation foundation and support for the screw rod 3, ensuring the stable rotation and lifting of the screw rod 3. It is an important structure for supporting and connecting the stabilizing mechanism and transmitting force.

[0048] Fixed block 6: Fixed block 6 is a guide component of sliding seat 7. There are three of them, which are fixed in a circle at equal intervals on the plane facing the wind box 2 at the input end of burner 1. The plane has sliding grooves, and sliding seat 7 slides in its sliding grooves. It provides a moving track and limit for sliding seat 7, ensuring that sliding seat 7 moves smoothly. It is a guide support structure for connecting and stabilizing mechanism.

[0049] Sliding seat 7: The sliding seat 7 is a stable actuator. It is slidably connected in the sliding groove of the fixed block 6. The bottom surface has a hinge block 2 connected to the connecting rod 13. The plane facing the input end of the burner 1 is equipped with a rubber block 8. Under the drive, it slides along the fixed block 6. The rubber block 8 fits against the connection between the burner and the air box to achieve tightening and fixation. It is a structure that directly acts on the connection part.

[0050] Rubber block 8: Rubber block 8 is a buffer fastening component, fixed on the plane of the sliding seat 7 facing the input end of the burner 1. It is an elastic block structure. When the sliding seat 7 is tightened, the rubber block 8 fits tightly against the connection between the burner and the air box, which can both enhance the friction and strengthen the connection, and buffer vibration to avoid hard contact damage to the components.

[0051] Limiting block 1 9: Limiting block 1 9 is a positioning component of the quick connection mechanism. It is symmetrically fixed on the outer wall of the wind box 2.

Under the action of spring 16, part of it is engaged in the snap-fit ​​slot of fixing plate 10 to achieve quick locking. It is the locking actuator of quick connection mechanism.

[0055] Link 13: Link 13 is a linkage component. Its two ends are respectively hinged to the hinge block one of the turntable 14 and the hinge block two of the sliding seat 7. It is a rod-shaped structure. When one sliding seat 7 moves, the turntable 14 is driven to rotate through the link 13, thereby causing the other two sliding seats 7 to move synchronously, realizing the linkage of the three sliding seats 7. It is a transmission component that connects and stabilizes the mechanism.

[0056] Turntable 14: Turntable 14 is the core component of the linkage. It is roughly triangular in shape and is coaxially rotatably connected to the input end of burner 1. There are hinge blocks at the three corners connected to the connecting rod 13. It rotates under the drive of the connecting rod 13, converting the movement of one sliding seat 7 into the synchronous movement of the other two sliding seats 7, realizing the coordinated action of the three sliding seats 7. It is the linkage hub connecting the stabilizing mechanism.

[0057] Air duct 15: Air duct 15 is an airflow guiding structure, which is spirally opened on the inner arc surface of the air box 2. It can guide the airflow in the air box 2 to form a vortex, making the air and fuel mix more evenly, improving combustion efficiency, and solving the problem of uneven airflow distribution in traditional straight-through air ducts.

[0058] Spring 16: Spring 16 is an elastic reset component. One end is fixed to the inner wall of the rectangular groove of the sliding block 12, and the other end is connected to the inner wall of the fixing plate on the limit block 11. It provides elastic force to the sliding block 12 so that it can be locked into the snap-fit ​​groove of the fixing plate 10 when there is no external force, thus achieving automatic locking. It is the power source for locking the quick connection mechanism.

[0059] Connecting block 17: Connecting block 17 is a positioning component, fixed on the end face of the air outlet of the air box 2, and coaxially sleeved with the connecting groove of the input end of the burner 1. It plays a preliminary positioning role during installation, ensuring that the air box 2 and the burner 1 are accurately connected, providing a basis for the operation of the subsequent quick connection mechanism. It is a key structure for installation and positioning.

[0060] Working principle: During installation, firstly, the connecting block 17 of the air box 2 is coaxially sleeved with the connecting groove of the input end of the burner 1 to complete the initial positioning and ensure that the two axes are aligned, laying the foundation for subsequent connection. At this time, the position of the limiting block 9 on the outer wall of the air box 2 corresponds to the position of the limiting block 11 on the outer wall of the burner 1, and their square sliding holes 1 and 2 are connected. Pull the handle of the fixing plate 10 so that the fixing plate 10 slides into the square sliding hole 2 of the limiting block 11 along the square sliding hole 1 of the limiting block 19. During the process, the fixing plate 10 squeezes the sliding block 12, forcing the sliding block 12 to compress the spring 16 and move towards the inside of the connecting hole of the limiting block 11. When the snap-fit ​​groove of the fixing plate 10 corresponds to the position of the sliding block 12, the spring 16 returns to its original position and pushes the sliding block 12 into the snap-fit ​​groove, realizing the quick locking of the burner 1 and the air box 2. No bolt tightening is required, and installation can be completed by a single person, greatly improving assembly efficiency.

[0061] To further enhance the connection stability, rotating the handle 4 drives the screw 3 to move downward along the threaded hole of the support seat 5. The bottom end of the screw 3 pushes the sliding seat 7 connected to it to slide along the sliding groove of the fixed block 6 towards the connection between the burner 1 and the air box 2. The sliding seat 7 drives the triangular turntable 14 to rotate through the connecting rod 13. The turntable 14 pulls the other two sliding seats 7 along the corresponding sliding groove of the fixed block 6 through the other two connecting rods 13, so that the three sliding seats 7 tighten towards the connection at the same time. The rubber block 8 on the sliding seat 7 fits tightly against the intersection of the burner 1 and the air box 2 as it slides, using the elasticity of the rubber to eliminate the assembly gap, enhance the friction, and at the same time buffer the vibration during equipment operation, prevent the connection from loosening, and ensure long-term stable operation.

[0062] During combustion, the spiral air grooves 15 on the inner arc surface of the air box 2 guide the airflow to form a vortex, allowing the air to rotate fully inside the air box 2 before entering the burner 1 and mixing evenly with the fuel. This solves the problem of uneven airflow distribution in traditional straight-through air ducts and improves combustion efficiency. If disassembly and maintenance are required, pull the handle of the fixing plate 10 in the opposite direction to disengage the locking groove from the sliding block 12, thereby releasing the lock of the quick-connect mechanism. Rotate the handle 4 in the opposite direction, and the screw 3 will drive the sliding seat 7 to reset. Through the linkage of the turntable 14 and the connecting rod 13, the three sliding seats 7 will be released, realizing the convenient separation of the burner 1 from the air box 2 and meeting the requirements for convenient maintenance.

[0063] Throughout the process, the quick-connect mechanism achieves efficient docking, the connection and stabilization mechanism enhances the fixing effect through the linkage of multiple components, and the air duct 15 optimizes the combustion conditions. The three work together to ensure that the device has both convenient installation, stable operation and high combustion efficiency.
