Description

Technical Field

[0001] This utility model belongs to the field of annealing furnace technology, and specifically relates to a zinc ash baffle assembly for the furnace nose of an annealing furnace. Background Technology

[0002] Annealing is a metal heat treatment process that can reduce residual stress in metals, stabilize dimensions, reduce deformation and cracking tendency, and eliminate structural defects. Generally, annealing furnaces are used to anneal metals. Before galvanizing, galvanized steel sheets need to be annealed in an annealing furnace. After annealing, the sheets are fed into a galvanizing bath containing molten zinc through a furnace nose. One end of the furnace nose is connected to the annealing furnace, and the other end extends into the galvanizing bath or zinc pot.

[0003] During the galvanizing process, the steam generated by the molten zinc enters the furnace nose. The zinc steam entering the furnace nose condenses into zinc particles, which adhere to the surface of the steel plate, resulting in an uneven surface after subsequent galvanizing.

[0004] To avoid the above-mentioned phenomena, a baffle is installed inside the furnace nose. After the steel plate is sent into the galvanizing tank containing molten zinc, the baffle closes the furnace nose to prevent the steam generated by the molten zinc from entering the furnace nose. However, existing furnace nose zinc ash baffle assemblies are mostly fixed or integrated structures, which are usually not disassembled, or disassembling the baffle usually requires entering the furnace, which is cumbersome and inconvenient, thus reducing the practicality of the furnace nose zinc ash baffle assembly. Utility Model Content

[0005] The present invention addresses the problem that baffles are installed inside the furnace nose to close the furnace nose after the steel plate is fed into the galvanizing tank containing molten zinc, thus preventing the steam generated by the molten zinc from entering the furnace nose. However, existing furnace nose zinc ash baffle assemblies are mostly fixed or integrated structures, which are usually not disassembled, or disassembly usually requires entering the furnace, which is cumbersome and inconvenient, thus reducing the practicality of the furnace nose zinc ash baffle assembly. This utility model proposes a furnace nose zinc ash baffle assembly for annealing furnaces to overcome the above-mentioned technical problems existing in the relevant technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The baffle body is slidably connected to the inner wall of the furnace nose body. A mounting seat is provided on one side of the furnace nose body.

[0008] Both the first sealing block and the furnace nose body are provided with sealing mechanisms, which are used to increase the sealing between the rotating shaft and the first sealing block, and between the furnace nose body and the rotating shaft.

[0009] A disassembly mechanism is fixedly installed at the right end of the rotating shaft. The disassembly mechanism facilitates the disassembly of the baffle body, thereby facilitating the replacement of the baffle body.

[0010] A drive mechanism is rotatably mounted on the mounting base. One end of the drive mechanism is rotatably connected to the lower end of the disassembly mechanism. The drive mechanism drives the baffle body to rotate through the disassembly mechanism, so that the baffle body changes angle to facilitate the discharge of the steel plate after annealing and to facilitate the sealing of the furnace nose body during the galvanizing of the steel plate.

[0011] Furthermore, the driving mechanism includes a rotating seat, which is fixedly connected to a mounting base. A cylinder is rotatably connected to the rotating seat, and a first connecting block is fixedly installed at the end of the cylinder away from the rotating seat.

[0012] Furthermore, the sealing mechanism includes a second sealing block, which is fixedly connected to the right side surface of the furnace nose body by bolts. The second sealing block is fixedly connected to the first sealing block. Two sealing flanges are slidably sleeved on the rotating shaft. The left side surfaces of the first and second sealing blocks are each provided with a sealing groove extending out of their right side surfaces. The left side surface of the furnace nose body is also provided with the sealing groove extending into it. The sealing flange on the left side is slidably connected to the sealing groove on the furnace nose body, and the sealing flange on the right side is slidably connected to the sealing groove on the second sealing block. The sealing flange on the left side is fixed to the left side surface of the furnace nose body by bolts, and the sealing flange on the right side is also fixed to the right side surface of the second sealing block by bolts. The sealing flanges are slidably sleeved on the outer surface of the rotating shaft.

[0013] Furthermore, the sealing mechanism also includes two connecting grooves, which are respectively formed on the furnace nose body and the first sealing block. The two connecting grooves are arranged in a mirror image and extend upward into the corresponding sealing groove. The nitrogen interface is fixedly connected to both the furnace nose body and the first sealing block. The two nitrogen interfaces communicate with the interior of the two connecting grooves. The second sealing block is fixedly connected to the nitrogen interface located on the right side.

[0014] Furthermore, the disassembly mechanism includes a connecting block, which is fixedly connected to the right end of the rotating shaft. An installation groove is provided inside the connecting block, and two positioning grooves are provided on the left side surface of the connecting block. A bidirectional threaded rod is rotatably connected between the inner walls of the two opposing sides of the positioning grooves, and the bidirectional threaded rod rotatably passes through the installation groove.

[0015] Furthermore, the disassembly mechanism also includes two positioning blocks, which are threaded onto the two opposite threads of the bidirectional threaded rod. The two threads of the bidirectional threaded rod are respectively located in the two positioning grooves. The two positioning blocks are slidably connected to the two positioning grooves, and a fixing block is slidably sleeved on the outer surface of the rotating shaft.

[0016] Furthermore, the disassembly mechanism also includes a sliding column, which is fixedly connected to the right side surface of the fixing block. The left side surface of the first connecting block is provided with a sliding groove extending out of its right side surface. The sliding groove is slidably connected to the sliding column. Limiting grooves are provided on the outer surfaces of the two adjacent positioning blocks. The limiting grooves are slidably connected to the fixing block.

[0017] Furthermore, the disassembly mechanism also includes a rotating rod, which is rotatably connected to the right side surface of the connecting block. The rotating rod rotates through the mounting groove, and a first bevel gear is fixedly sleeved on the outer surface of the bidirectional threaded rod. A second bevel gear is fixedly connected to one end of the rotating rod that passes through the mounting groove, and the first bevel gear and the second bevel gear mesh with each other.

[0018] This utility model has the following beneficial effects:

[0019] This utility model uses a rotating shaft to drive the baffle body to be disassembled from the furnace nose body through the first sealing block, thereby removing the baffle body from the furnace nose body, which facilitates the replacement of the baffle body. The replacement is convenient and quick, saves manpower, and increases the practicality of the zinc ash baffle assembly for the furnace nose of the annealing furnace.

[0020] This utility model completes the installation by sliding the sliding column on the fixed block into the sliding groove, and then rotating the rotating rod to drive the relative displacement of the two positioning blocks, clamping the fixed block in the two limiting grooves. The installation is convenient, quick, labor-saving and efficient, thereby increasing the practicality of the zinc ash baffle assembly for the annealing furnace nose.

[0021] This invention features a vertical baffle body that shields and seals the inside of the furnace nose, preventing ash and slag formed by zinc evaporation from entering the furnace and reducing the risk of furnace roller nodules. When the starting cylinder drives the baffle body to rotate to a horizontal position, the annealed steel plate can be discharged from the furnace nose for galvanizing.

[0022] This invention improves the quality of steel plate annealing by introducing nitrogen gas into the connecting groove through the nitrogen port, which then purges the nitrogen gas into the sealing groove, thereby creating positive pressure inside the sealing groove. This prevents external air from entering the furnace nose body through the sealing groove, thus preventing oxygen from seeping into the furnace nose body and causing coating oxidation.

[0023] 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

Detailed Implementation

[0034] 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.

[0035] 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.

[0036] Please see Figures 1-7 As shown, this utility model is a zinc ash baffle assembly for an annealing furnace nose, including a furnace nose body 1. A disassembly groove 2 is provided on the left side surface of the furnace nose body 1. A first sealing block 5 is slidably connected in the disassembly groove 2. A rotating shaft 3 is provided inside the furnace nose body 1. A baffle body 4 is fixedly sleeved on the outer surface of the rotating shaft 3. The baffle body 4 is slidably connected to the inner wall of the furnace nose body 1. A mounting seat 15 is provided on one side of the furnace nose body 1.

[0037] Both the first sealing block 5 and the furnace nose body 1 are provided with sealing mechanisms. The sealing mechanisms are used to increase the sealing between the rotating shaft 3 and the first sealing block 5, and between the furnace nose body 1 and the rotating shaft 3.

[0038] A disassembly mechanism is fixedly installed at the right end of the rotating shaft 3. The disassembly mechanism facilitates the disassembly of the baffle body 4, thereby facilitating the replacement of the baffle body 4.

[0039] A drive mechanism is rotatably mounted on the mounting base 15. One end of the drive mechanism is rotatably connected to the lower end of the disassembly mechanism. The drive mechanism drives the baffle body 4 to rotate through the disassembly mechanism, so that the angle of the baffle body 4 changes, so as to facilitate the discharge of the steel plate after annealing and to facilitate the sealing of the furnace nose body 1 during the galvanizing of the steel plate.

[0040] In one embodiment, the sealing mechanism includes a second sealing block 10, which is bolted to the right side surface of the furnace nose body 1. The second sealing block 10 is also bolted to the first sealing block 5. Two sealing flanges 7 are slidably fitted on the rotating shaft 3. The left side surfaces of the first sealing block 5 and the second sealing block 10 are each provided with a sealing groove 6 extending out of their right side surfaces. The left side surface of the furnace nose body 1 is also provided with the sealing groove 6 extending into it. The sealing flange 7 on the left side is slidably connected to the sealing groove 6 on the furnace nose body 1, and the sealing flange 7 on the right side is slidably connected to the sealing groove 6 on the second sealing block 10. The sealing flange 7 on the left side is bolted to the left side surface of the furnace nose body 1, and the sealing flange 7 on the right side is also bolted to the right side surface of the second sealing block 10. The sealing flange 7 is slidably fitted on the outer surface of the rotating shaft 3.

[0041] The sealing mechanism also includes two connecting grooves 14, which are respectively opened on the furnace nose body 1 and the first sealing block 5. The two connecting grooves 14 are arranged in a mirror image and extend upward into the corresponding sealing grooves 6. The nitrogen interface 13 is fixedly connected to both the furnace nose body 1 and the first sealing block 5. The two nitrogen interfaces 13 communicate with the interior of the two connecting grooves 14. The second sealing block 10 is fixedly connected to the nitrogen interface 13 located on the right side.

[0042] In addition, in specific applications, the second sealing block 10 has a sealing effect on the first sealing block 5, and the sealing flange 7 has a sealing effect on the sealing groove 6. When nitrogen is introduced into the connecting groove 14 through the nitrogen port 13, the nitrogen is blown into the sealing groove 6 through the connecting groove 14, thereby creating a positive pressure in the sealing groove 6. This prevents external air from entering the furnace nose body 1 through the sealing groove 6, and thus prevents oxygen from seeping into the furnace nose body 1 and causing the coating to oxidize, thereby improving the quality of steel plate annealing.

[0043] In one embodiment, the drive mechanism includes a rotating seat 16, which is fixedly connected to a mounting base 15. A cylinder 17 is rotatably connected to the rotating seat 16, and a first connecting block 18 is fixedly installed at one end of the cylinder 17 away from the rotating seat 16.

[0044] In one embodiment, the disassembly mechanism includes a connecting block 22, which is fixedly connected to the right end of the rotating shaft 3. An installation groove 9 is provided in the connecting block 22, and two positioning grooves 23 are provided on the left side surface of the connecting block 22. A bidirectional threaded rod 26 is rotatably connected between the inner walls of the two opposing sides of the two positioning grooves 23, and the bidirectional threaded rod 26 rotatably passes through the installation groove 9.

[0045] The disassembly mechanism also includes two positioning blocks 24, which are threaded onto the two opposite threads of the bidirectional threaded rod 26. The two threads of the bidirectional threaded rod 26 are respectively located in the two positioning grooves 23. The two positioning blocks 24 are slidably connected to the two positioning grooves 23. The outer surface of the rotating shaft 3 is slidably fitted with a fixing block 19.

[0046] The disassembly mechanism also includes a sliding column 20, which is fixedly connected to the right side surface of the fixing block 19. The left side surface of the first connecting block 18 is provided with a sliding groove 21 extending out of its right side surface. The sliding groove 21 is slidably connected to the sliding column 20. Limiting grooves 25 are provided on the outer surfaces of the two adjacent positioning blocks 24. The limiting grooves 25 are slidably connected to the fixing block 19.

[0047] The disassembly mechanism also includes a rotating rod 8, which is rotatably connected to the right side surface of the connecting block 22. The rotating rod 8 rotates through the mounting groove 9. A first bevel gear 11 is fixedly sleeved on the outer surface of the bidirectional threaded rod 26. A second bevel gear 12 is fixedly connected to one end of the rotating rod 8 that passes through the mounting groove 9. The first bevel gear 11 and the second bevel gear 12 are meshed together.

[0048] In addition, in specific applications, the mounting base 15 is fixed to the zinc pot or galvanizing tank by bolts. The extension and retraction of the cylinder 17 drives the first connecting block 18 to move. Because the cylinder 17 is rotatably connected to the rotating base 16, and the first connecting block 18 is slidably sleeved on the sliding column 20, the movement of the first connecting block 18 will push the fixed block 19 to rotate around the rotating shaft 3, thereby driving the baffle body 4 fixed on the rotating shaft 3 to rotate. In the initial state, the baffle body 4 is in a vertical state. At this time, the baffle body 4 shields and seals the inside of the furnace nose body 1 to prevent the ash slag formed by zinc evaporation from entering the furnace and reduce the risk of furnace roller nodule formation. When the cylinder 17 drives the baffle body 4 to rotate to a horizontal state, the annealed steel plate can be discharged from the furnace nose body 1 for galvanizing.

[0049] Furthermore, in specific applications, when replacing the baffle body 4, it is necessary to first unscrew the bolts fixing the sealing flange 7 to disassemble the sealing flange 7, thereby sliding the sealing flange 7 off the rotating shaft 3. Then, unscrew the bolts fixing the second sealing block 10 to disassemble the second sealing block 10. Then, rotate the rod 8, which drives the second bevel gear 12 fixed thereon to rotate. The second bevel gear 12 synchronously drives the first bevel gear 11 meshing with it to rotate, so that the second bevel gear 12 synchronously drives the bidirectional threaded rod 26 to rotate. The rotation of the bidirectional threaded rod 26 synchronously drives the two positioning blocks 24 to move relative to each other or in opposite directions. When the two positioning blocks 24 move away from each other, they simultaneously drive the two limiting grooves 25 to slide until they do not contact the fixed block 19. At this time, the fixed block 19 can be pushed backward so that the fixed block 19 drives the second sealing block 10 to move backward, thereby driving the second sealing block 10 to slide out of the sliding groove 21. At this time, the sliding column 20 is disengaged from the first connecting block 18. Then, the rotating shaft 3 can be pulled out to drive the baffle body 4 to be disassembled from the furnace nose body 1 through the first sealing block 5. This makes it easier to replace the baffle body 4, which is convenient and quick, saves manpower, and increases the practicality of the zinc ash baffle assembly of the annealing furnace nose.

[0050] During installation, the two sealing flanges 7 are fitted onto the outer surface of the rotating shaft 3. Then, the second sealing block 10 is fixed to the furnace nose body 1 with bolts. The two sealing flanges 7 are respectively fixed on the furnace nose body 1 and the second sealing block 10. Then, the fixing block 19 is slid, and the right side surface of the fixing block 19 contacts the left inner wall of the connecting block 22. During this process, the sliding column 20 on the fixing block 19 is also slid into the sliding groove 21. Then, rotating the rotating rod 8 will drive the two positioning blocks 24 to move relative to each other, clamping the fixing block 19 in the two limiting grooves 25, thus completing the installation. The installation is convenient, quick, labor-saving, and efficient, thereby increasing the practicality of the zinc ash baffle assembly of the annealing furnace nose.

[0051] Through the above technical solution, 1. The baffle body 4 is disassembled from the furnace nose body 1 by rotating the shaft 3 and passing through the first sealing block 5, thereby removing the baffle body 4 from the furnace nose body 1, which facilitates the replacement of the baffle body 4. The replacement is convenient and quick, saves manpower, and increases the practicality of the zinc ash baffle assembly of the annealing furnace nose.

[0052] The installation can be completed by sliding the sliding post 20 on the fixed block 19 into the sliding groove 21, and then rotating the rotating rod 8 to drive the two positioning blocks 24 to move relative to each other, clamping the fixed block 19 in the two limiting grooves 25. The installation is convenient, quick and labor-saving, and efficient, thereby increasing the practicality of the zinc ash baffle assembly of the annealing furnace nose.

[0053] When the baffle body 4 is in a vertical position, it shields and seals the inside of the furnace nose body 1, preventing the ash slag formed by zinc evaporation from entering the furnace and reducing the risk of furnace roller nodules. When the starting cylinder 17 drives the baffle body 4 to rotate to a horizontal position, the annealed steel plate can be discharged from the furnace nose body 1 for galvanizing.

[0054] When nitrogen is introduced into the connecting groove 14 through the nitrogen port 13, the nitrogen is blown into the sealing groove 6 through the connecting groove 14, thereby creating a positive pressure in the sealing groove 6. This prevents external air from entering the furnace nose body 1 through the sealing groove 6, and thus prevents oxygen from seeping into the furnace nose body 1 and causing the coating to oxidize, thereby improving the quality of steel plate annealing.
