[0030] This application provides a modular low-NOx burner. By incorporating a buffer assembly, the leaf spring absorbs most of the energy generated by bumps during deformation, thus providing buffer protection for the burner body. The ball bearings reduce friction between the leaf spring and the mounting plate. A reinforcement mechanism, consisting of a ring clamp, insert plate, positioning hole, insert block, and fasteners, effectively secures the flange, strengthening the connection between the connecting pipe and the burner body. The fasteners also effectively secure the ring clamp, ensuring that both ends of the ring clamp remain closed.
[0031] Example 1
[0032] The technical solution in this application embodiment effectively solves the problems of existing modular low-NOx burners, such as the lack of limiting on the outer side of the flange connection, which leads to loosening and affects stability during use; and the lack of a cushioning device at the bottom of existing modular low-NOx burners, making them susceptible to damage during transportation. The overall approach is as follows:
[0033] like Figures 1 to 5 In view of the problems existing in the prior art, this utility model provides a splicing low-NOx burner, including a mounting plate 1, a burner body 2 is arranged on the top of the mounting plate 1, a buffer assembly 6 is arranged between the burner body 2 and the mounting plate 1, a flange 4 is arranged on one side of the burner body 2, a connecting pipe 3 is connected to the burner body 2 through the flange 4, and a reinforcing mechanism 5 is sleeved on the outside of the flange 4.
[0034] By adopting the above technical solution, during use, the burner body 2 is connected to the connecting pipe 3 through the flange 4. At the same time, the reinforcement mechanism 5 is used to fix the flange 4 to strengthen the connection between the connecting pipe 3 and the burner body 2, and to prevent the connecting pipe 3 from separating from the burner body 2 due to the loosening of the flange 4. Meanwhile, the buffer assembly 6 can buffer and protect the burner body 2 to prevent the burner body 2 from being damaged during transportation and transfer.
[0035] Specifically, the buffer assembly 6 includes a connecting plate 60, which is welded to the bottom of the burner body 2. Slider 61 is fixedly connected to both sides of the connecting plate 60. Limiting grooves 62 corresponding to slider 61 are opened on both sides of the inside of the mounting plate 1. Leaf springs 63 are fixedly connected to the four corners of the bottom of the connecting plate 60. Ball bearings 64 are provided on both sides of the bottom of the leaf springs 63.
[0036] By adopting the above technical solution, the burner body 2 will be subjected to bumps during the transfer process. The force generated by the bumps will be absorbed by the leaf spring 63. The leaf spring 63 will absorb most of the energy generated by the bumps during the deformation process, thereby achieving buffer protection for the burner body 2. The ball bearing 64 can reduce the friction between the leaf spring 63 and the mounting plate 1.
[0037] Example 2
[0038] like Figures 1 to 5 The reinforcement mechanism 5 includes an annular clamp 51, which is sleeved on the outside of the flange 4. A plate 52 is fixedly connected to one end of the annular clamp 51. A positioning hole 53 is provided on one side of the plate 52. A corresponding insert block 54 is fixedly connected to the other end of the annular clamp 51. A fixing member 55 is inserted into one side of the insert block 54.
[0039] By adopting the above technical solution, the annular clamp 51 is sleeved on the outside of the flange 4, the insert plate 52 is inserted into the insert block 54, and the fastener 55 can fix the insert plate 52 through the positioning hole 53, thereby achieving the fixation of the annular clamp 51.
[0040] Specifically, the fixing component 55 includes a positioning rod 551, which is inserted into one side of the insert block 54. A limiting plate 552 is fixedly sleeved on the outside of the positioning rod 551, and a restoring spring 553 is arranged around the middle of the positioning rod 551. The two ends of the restoring spring 553 are fixedly connected to the limiting plate 552 and the inner wall of the insert block 54, respectively.
[0041] By adopting the above technical solution, the positioning rod 551 enters the positioning hole 53 under the action of the restoring spring 553, which can fix the insert plate 52.
[0042] Specifically, a magnetic block 554 is fixedly connected to one end of the positioning rod 551, and a magnetic plate 555 with opposite magnetism to the magnetic block 554 is fixedly connected to the inner side of the insertion block 54.
[0043] By adopting the above technical solution, the attraction between the magnetic block 554 and the magnetic plate 555 can enhance the fixing effect on the insert plate 52.
[0044] Working principle: During use, the burner body 2 is connected to the connecting pipe 3 via the flange 4. Simultaneously, the reinforcing mechanism 5 secures the flange 4 to strengthen the connection between the connecting pipe 3 and the burner body 2, preventing the connecting pipe 3 from separating from the burner body 2 due to loosening of the flange 4. Meanwhile, the buffer assembly 6 provides cushioning protection for the burner body 2, preventing damage during transportation and transfer. Specifically, the annular clamp 51 is fitted over the flange 4, and the insert plate 52 is inserted into the insert block 54. Simultaneously, the fixing component 55 can secure the insert plate 52 through the positioning hole 53. The ring clamp 51 is fixed in place. When the fixing part 55 is in use: the positioning rod 551 enters the positioning hole 53 under the force of the restoring spring 553, which can fix the insert plate 52. At the same time, the magnetic block 554 attracts the magnetic plate 555, which can enhance the fixing effect of the insert plate 52. During the transfer process, the burner body 2 will be bumped. The force generated by the bump will be absorbed by the leaf spring 63. The leaf spring 63 will absorb most of the energy generated by the bump during the deformation process, thereby achieving buffer protection for the burner body 2. The ball 64 can reduce the friction between the leaf spring 63 and the mounting plate 1.
[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
