Description

Technical Field

[0001] This utility model belongs to the field of galvanizing line production technology, and specifically relates to a burner assembly used in the galvanizing line production process. Background Technology

[0002] In the galvanizing process, the galvanizing process is a crucial step in improving the corrosion resistance and surface quality of metal materials. This process typically involves continuous annealing, reduction, and hot-dip galvanizing of steel strips or plates. The annealing furnace or heating furnace, as the core equipment, requires a stable high-temperature environment provided by the combustion system to ensure the metal substrate reaches the required temperature and surface condition for the process. The burner body, as the core component of the combustion system, directly affects the furnace temperature uniformity, energy efficiency, pollutant emission levels, and the final quality of the galvanized product.

[0003] In existing technologies, the burner body's flaming end is typically rigidly connected to the nozzle via fixing bolts. Because the nozzle operates at high temperatures for extended periods, its structure is susceptible to damage from thermal stress, oxidation, or corrosion, leading to deterioration or even failure of the flaming effect. To ensure combustion stability, damaged nozzles need to be replaced. However, traditional bolt fixing methods are cumbersome and time-consuming—multiple fasteners must be disassembled one by one during the operation, and in high-temperature environments, threads are prone to seizing or bolts to break. This not only increases maintenance difficulty but may also further damage components due to improper disassembly, affecting production continuity and equipment reliability. Utility Model Content

[0004] To address the issue that multiple bolts need to be rotated when replacing the nozzle on the burner body, this invention proposes a burner assembly for use in the galvanizing line production process, thereby overcoming the aforementioned technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a burner assembly used in the production process of a galvanizing line, including a support assembly. The support end of the support assembly has a rotating groove, and the burner body is rotatably connected inside the rotating groove. The support end of the support assembly is provided with an angle adjustment assembly corresponding to the burner body. The flame-emitting end of the burner body is provided with a nozzle. A rotating snap-fit ​​assembly is provided between the burner body and the nozzle. A limit assembly is provided on the outside of the burner body and the nozzle.

[0007] The angle adjustment component is used to adjust the flame angle of the burner body, the rotary locking component is used to lock the nozzle to the flame end of the burner body, and the limiting component is used to limit the nozzle locked on the flame end.

[0008] Furthermore, the support assembly includes a mounting ring, and a plurality of support legs are fixedly mounted on the outer side of the mounting ring, and the rotating groove is provided on each of the plurality of support legs.

[0009] Furthermore, the angle adjustment component includes a rotating shaft, which is fixedly connected to the outside of the burner body. One end of the rotating shaft passes through the support leg and is fixedly connected to an adjustment disc. The outer surface of the adjustment disc is provided with several positioning holes. A moving groove is provided on one side of the support leg. A moving frame is movably connected inside the moving groove. A positioning rod is fixedly connected to the bottom end of the moving frame.

[0010] Furthermore, a guide rod is fixedly connected to the inner wall of the movable slot, the guide rod is movably connected to the movable frame, a drive screw is threadedly connected to one side of the support leg, the bottom end of the drive screw is rotatably connected to the movable frame, and a rotating handle is fixedly connected to one side of the adjusting plate.

[0011] Furthermore, the rotating snap-fit ​​assembly includes a fixing ring, which is fixedly installed on the flame-emitting end of the burner body. A sealing groove is provided on one side of the fixing ring, and a sealing ring is movably connected inside the sealing groove. A connecting ring is fixedly connected to one side of the sealing ring, and the nozzle is fixedly connected to one side of the connecting ring.

[0012] Furthermore, the inner wall of the sealing groove is provided with a snap-fit ​​groove, and a snap-fit ​​block is movably connected inside the snap-fit ​​groove. The snap-fit ​​block is fixedly connected to the sealing ring. The inner wall of the snap-fit ​​groove is provided with an insertion groove, which extends to the outside of the fixing ring.

[0013] Furthermore, the limiting component includes a limiting groove, which is opened on the outer surface of both the fixed ring and the connecting ring. A limiting plate is rotatably connected inside the limiting groove opened on the outer surface of the fixed ring, and a control rod is fixedly connected to the front of the limiting plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a burner to drive a rotating snap-fit ​​assembly, thereby releasing the nozzle from its snap-fit ​​limit. The nozzle can then be directly pulled out from the flame-emitting end of the burner body. Compared to traditional bolt-fixing methods, this snap-fit ​​design eliminates the need to individually disassemble and reassemble multiple fasteners, significantly simplifying the operation process. Furthermore, the rotating snap-fit ​​assembly is less prone to locking or failure due to thermal expansion or oxidation in high-temperature environments, avoiding the risk of thread engagement and improving disassembly efficiency and maintenance reliability, ensuring efficient and continuous equipment maintenance during galvanizing line production.

[0016] This invention uses a drive screw to move the moving frame upwards. At this time, the positioning rod moves out of the positioning hole under the drive of the moving frame. Then, by rotating the handle, adjusting plate, and rotating shaft, the burner body is rotated to a suitable angle. The drive screw is then used again to push the moving frame, allowing the positioning rod to move into the corresponding positioning hole and position the burner body after angle adjustment. This design allows the burner body and the flame emitted by the nozzle to be adjusted according to actual conditions, thus ensuring the heating effect in the furnace.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a burner assembly used in the production process of a galvanizing line, including a support assembly 1. The support end of the support assembly 1 is provided with a rotating groove 2. The burner body 3 is rotatably connected inside the rotating groove 2. The support end of the support assembly 1 is provided with an angle adjustment assembly 4 corresponding to the burner body 3. The flame-emitting end of the burner body 3 is provided with a nozzle 5. A rotating snap-fit ​​assembly 6 is provided between the burner body 3 and the nozzle 5. A limit assembly 7 is provided on the outside of the burner body 3 and the nozzle 5.

[0031] The angle adjustment component 4 is used to adjust the flame angle of the burner body 3, the rotation snap-fit ​​component 6 is used to snap the nozzle 5 to the flame end of the burner body 3, and the limiting component 7 is used to limit the nozzle 5 snapped on the flame end.

[0032] When replacing the damaged nozzle 5, the limiting end of the limiting component 7 is rotated so that the limiting end no longer limits the rotating snap-fit ​​component 6. Then, the snap-fit ​​end of the rotating snap-fit ​​component 6 is rotated and pulled out through the nozzle 5, so that the nozzle 5 can be detached from the burner body 3.

[0033] The nozzle 5 drives the rotating snap-fit ​​assembly 6 to rotate, thereby releasing the snap-fit ​​limit on the nozzle 5. The nozzle 5 can then be directly pulled out, allowing it to move from the flame-emitting end of the burner body 3. Compared to traditional bolt fixing methods, this snap-fit ​​design eliminates the need to disassemble and reassemble multiple fasteners individually, significantly simplifying the operation process. Furthermore, the rotating snap-fit ​​assembly 6 is less prone to locking or failure due to thermal expansion or oxidation in high-temperature environments, avoiding the risk of thread engagement and improving disassembly efficiency and maintenance reliability, ensuring the high efficiency and continuity of equipment maintenance during galvanizing line production.

[0034] In one embodiment, the support component 1 includes a mounting ring 101, and a plurality of support legs 102 are fixedly mounted on the outer side of the mounting ring 101. The rotating groove 2 is provided on each of the plurality of support legs 102.

[0035] By installing the heating furnace inside the mounting ring 101, the mounting ring 101 can support the heating furnace. At the same time, since the rotating grooves 2 opened on the mounting ring 102 are all equipped with burner bodies 3, the heating furnace is heated more evenly when the burner bodies 3 are used to heat the heating furnace.

[0036] In one embodiment, the angle adjustment component 4 includes a rotating shaft 401, which is fixedly connected to the outside of the burner body 3. One end of the rotating shaft 401 passes through the support leg 102 and is fixedly connected to an adjustment disc 402. The outer surface of the adjustment disc 402 is provided with a plurality of positioning holes 403. A moving groove 404 is provided on one side of the support leg 102. A moving frame 405 is movably connected inside the moving groove 404. A positioning rod 406 is fixedly connected to the bottom end of the moving frame 405.

[0037] By moving the movable frame 405 upwards, the positioning rod 406 can move out of the positioning hole 403 under the drive of the movable frame 405. Then, the rotating shaft 401 is rotated by the adjusting plate 402. At this time, the burner body 3 can rotate inside the rotating groove 2 under the drive of the rotating shaft 401. When the burner body 3 rotates to a suitable angle, the movable frame 405 is moved again, so that the positioning rod 406 can move into the corresponding positioning hole 403. At this time, the positioning rod 406 can position the burner body 3 with the angle adjusted through the positioning hole 403. The above settings allow the flame emitted by the burner body 3 and the nozzle 5 to be adjusted according to the actual situation, thereby ensuring the heating effect when heating the furnace.

[0038] In one embodiment, for the aforementioned movable slot 404, a guide rod 407 is fixedly connected to the inner wall of the movable slot 404, the guide rod 407 is movably connected to the movable frame 405, a drive screw 408 is threadedly connected to one side of the support leg 102, the bottom end of the drive screw 408 is rotatably connected to the movable frame 405, and a rotating handle 409 is fixedly connected to one side of the adjusting disc 402.

[0039] By rotating the drive screw 408, the movable frame 405 can move under the drive of the drive screw 408 and the guidance of the guide rod 407. Since the drive screw 408 is threadedly connected to the support leg 102, this arrangement ensures that when the movable frame 405 moves the positioning rod 406 into the positioning hole 403, the positioning rod 406 will not move out of the positioning hole 403 at will, thus ensuring the firmness of the positioning rod 406 in positioning the adjusting plate 402 through the positioning hole 403. The adjusting plate 402 can be rotated by rotating the handle 409, which makes it convenient to rotate the adjusting plate 402.

[0040] In one embodiment, the rotary snap-fit ​​assembly 6 includes a retaining ring 601, which is fixedly installed on the flame-spraying end of the burner body 3. A sealing groove 602 is provided on one side of the retaining ring 601, and a sealing ring 603 is movably connected inside the sealing groove 602. A connecting ring 604 is fixedly connected to one side of the sealing ring 603, and the nozzle 5 is fixedly connected to one side of the connecting ring 604.

[0041] When installing the nozzle 5, the sealing ring 603 is moved directly into the sealing groove 602, and the connecting ring 604 is brought into contact with the fixing ring 601. Under the sealing of the sealing ring 603 and the sealing groove 602, the sealing performance at the connection between the connecting ring 604 and the fixing ring 601 can be guaranteed. At the same time, the sealing ring 603 and the sealing groove 602 can also position the nozzle 5, so that the nozzle 5 can always be collinear with the axis of the burner body 3.

[0042] In one embodiment, for the sealing groove 602, the inner wall of the sealing groove 602 is provided with a snap-fit ​​groove 605, and a snap-fit ​​block 606 is movably connected inside the snap-fit ​​groove 605. The snap-fit ​​block 606 is fixedly connected to the sealing ring 603. The inner wall of the snap-fit ​​groove 605 is provided with an insertion groove 607, and the insertion groove 607 extends to the outside of the fixing ring 601.

[0043] When the sealing ring 603 is moved into the sealing groove 602, the snap-fit ​​block 606 is aligned with the insertion groove 607, so that the snap-fit ​​block 606 on the sealing ring 603 can move into the snap-fit ​​groove 605 through the insertion groove 607. After the sealing ring 603 is completely moved into the sealing groove 602, the connecting ring 604 is rotated by the nozzle 5, so that the snap-fit ​​block 606 can rotate into the snap-fit ​​groove 605 under the drive of the connecting ring 604. At this time, the snap-fit ​​groove 605 can limit the connecting ring 604 through the snap-fit ​​block 606, so that the connecting ring 604 and the fixed ring 601 will not separate arbitrarily.

[0044] In one embodiment, the limiting component 7 includes a limiting groove 701, which is provided on the outer surfaces of both the fixing ring 601 and the connecting ring 604. A limiting plate 702 is rotatably connected inside the limiting groove 701 provided on the outer surface of the fixing ring 601, and a control rod 703 is fixedly connected to the front side of the limiting plate 702.

[0045] When the snap-fit ​​block 606 rotates into the snap-fit ​​groove 605, the limiting groove 701 on the fixing ring 601 aligns with the limiting groove 701 on the connecting ring 604. At this time, the limiting plate 702 is rotated directly, so that the limiting plate 702 can rotate into the limiting groove 701 opened on the connecting ring 604 and limit the connecting ring 604, so that the connecting ring 604 in contact with the fixing ring 601 will not rotate arbitrarily.

[0046] Through the above technical solution, 1. The nozzle 5 drives the rotating snap-fit ​​assembly 6 to rotate, thereby releasing the snap-fit ​​limit on the nozzle 5. Then, the nozzle 5 can be directly pulled out to move it out from the flame-emitting end of the burner body 3. Compared with the traditional bolt fixing method, this snap-fit ​​setting does not require disassembling and assembling multiple fasteners one by one, which significantly simplifies the operation process. Meanwhile, the rotating snap-fit ​​assembly 6 is not prone to locking or failure due to thermal expansion or oxidation in high-temperature environments, which avoids the risk of thread engagement and improves disassembly efficiency and maintenance reliability, ensuring the efficiency and continuity of equipment maintenance during the galvanizing line production process; 2. The moving frame 405 is moved upward by the drive screw 408. At this time, the positioning rod 406 moves from the positioning hole 403 under the drive of the moving frame 405. Then, by rotating the handle 409, adjusting plate 402 and rotating shaft 401, the burner body 3 is rotated to a suitable angle. The drive screw 408 is driven again to push the moving frame 405, so that the positioning rod 406 can move into the corresponding positioning hole 403 and position the burner body 3 after the angle adjustment is completed; The above settings allow the flames emitted by the burner body 3 and the nozzle 5 to be adjusted according to the actual situation, so as to ensure the heating effect when heating the furnace.
