Description

Technical Field

[0001] This utility model relates to the field of annealing furnace technology, specifically to a gas combustion device for a galvanizing annealing furnace. Background Technology

[0002] The gas combustion device of a galvanizing annealing furnace is a key component of industrial heat treatment equipment, mainly used to provide a heat source for the annealing furnace.

[0003] The existing gas combustion device of the galvanizing annealing furnace delivers air and gas to the burner through air pipes and gas pipes. The gas pipes deliver gas to different burners through multiple sets of gas branch pipes. Since the multiple sets of gas branch pipes are installed independently on the gas pipe, the installation and disassembly of the gas branch pipes are very time-consuming and labor-intensive, resulting in low maintenance efficiency of the gas pipes and gas branch pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a gas combustion device for a galvanizing annealing furnace, so as to solve the problem mentioned in the background art that multiple sets of gas branch pipes are independently installed on the gas pipe, which makes the installation and disassembly of the gas branch pipes very time-consuming and laborious, resulting in low maintenance efficiency of the gas pipe and gas branch pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas combustion device for a galvanizing annealing furnace, comprising a gas main pipe, gas branch pipes fixedly installed on the surface of the gas main pipe, a flame burner fixedly installed on the surface of the gas branch pipes, an air branch pipe fixedly installed on the surface of the flame burner, an air main pipe fixedly installed at the end of the air branch pipe away from the flame burner, an installation mechanism provided on the surface of the gas main pipe, the installation mechanism including a connecting pipe fixedly connected to the surface of the gas main pipe, and a sealing ring fixedly connected to the surface of the connecting pipe. A branch pipe is inserted into the surface of a connecting pipe. A fixing block is fixedly connected to the surface of the main gas pipe. A double-acting screw is rotatably connected to the surface of the fixing block. A knob is fixedly connected to one end of the double-acting screw. A movable block is threadedly connected to the surface of the double-acting screw. An adjusting rod is rotatably connected to the surface of the movable block. A connecting rod is fixedly connected to the surface of the gas branch pipe. A connecting block is fixedly connected to the surface of the connecting rod. The end of the adjusting rod away from the movable block is rotatably connected to the connecting block. A guide rod is fixedly connected to the surface of the main gas pipe. The guide rod slides on the surface of the connecting rod.

[0006] Preferably, a first support block is fixedly connected to the surface of the gas main pipe, and a first support screw is threadedly connected to the surface of the first support block; a second support block is fixedly connected to the surface of the air main pipe, and a second support screw is threadedly connected to the surface of the second support block.

[0007] Preferably, multiple sets of connecting pipes and gas branch pipes are provided and correspond to each other. A insertion groove is opened on the surface of the connecting pipe, and the sealing ring is fixedly connected to the insertion groove of the connecting pipe. The gas branch pipe presses the sealing ring on the insertion groove of the connecting pipe.

[0008] Preferably, the movable block has a guide hole and a threaded hole on its surface. The movable block slides on the surface of the gas main pipe through the guide hole. The bidirectional lead screw is threadedly connected to the threaded hole of the movable block. The bidirectional lead screw drives the movable block to slide on the surface of the gas main pipe by rotation. There are two sets of movable blocks, and the sliding directions of the two sets of movable blocks are opposite.

[0009] Preferably, the connecting rod is fixedly connected between multiple sets of gas branch pipes, and a guide hole is provided on the surface of the connecting rod. The guide rod slides on the guide hole of the connecting rod. During the sliding process, the movable block pushes the gas main pipe and the guide rod to slide on one side of the connecting rod through the adjusting rod and the connecting block.

[0010] Preferably, the first support block is provided in multiple sets and is evenly distributed on the surface of the gas main pipe. The surface of the first support block is provided with threaded holes, and the first support screw is threadedly connected to the threaded holes of the first support block.

[0011] Preferably, multiple sets of the second support blocks are provided and evenly distributed on the surface of the air main pipe. Threaded holes are opened on the surface of the second support blocks, and the second support screw is threadedly connected to the threaded holes of the second support blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This combustion device involves rotating a knob on the surface of a fixed block. The knob drives a two-way lead screw to rotate, which in turn causes a movable block to slide on the surface of the gas main pipe. During this sliding motion, the movable block drives an adjusting rod to rotate. As the adjusting rod rotates, it pushes the gas main pipe and the connecting rod apart through the movable block and the connecting block, causing the guide rod to slide in the guide hole of the connecting rod. This changes the distance between the gas main pipe and the gas branch pipes, allowing the gas branch pipes to detach from the insertion slot of the connecting pipe. This enables the simultaneous disassembly of multiple sets of gas branch pipes on the gas main pipe. Similarly, multiple sets of gas branch pipes can be installed on the gas main pipe simultaneously. By simultaneously installing and disassembling multiple sets of gas branch pipes on the gas main pipe, the maintenance efficiency of the gas main pipe and gas branch pipes is improved.

[0014] 2. In this combustion device, when installing the gas main pipe and air main pipe, the first support screw is rotated on the surface of the first support block. When the first support screw contacts the mounting surface, it supports the gas main pipe through the first support block. The second support screw is rotated on the surface of the second support block. When the second support screw contacts the mounting surface, it supports the air main pipe through the second support block. No separate support device is required, making the installation of the gas main pipe and air main pipe simpler and more convenient. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] The gas combustion device for a galvanizing annealing furnace includes a main gas pipe 1, a gas branch pipe 11 fixedly installed on the surface of the main gas pipe 1, a flame burner 12 fixedly installed on the surface of the gas branch pipe 11, an air branch pipe 14 fixedly installed on the surface of the flame burner 12, and an air main pipe 13 fixedly installed at the end of the air branch pipe 14 away from the flame burner 12. Valves are installed on the main gas pipe 1, gas branch pipe 11, flame burner 12, and air main pipe 13 to control the output of gas and air. An installation mechanism is provided on the surface of the main gas pipe 1, including a connecting pipe 2 fixedly connected to the surface of the main gas pipe 1. A sealing ring 21 is fixedly connected to the surface of the connecting pipe 2. The gas branch pipe 11 is inserted into the surface of the connecting pipe 2. A fixing block 22 is fixedly connected to the surface of the main gas pipe 1, and a rotating connection is made on the surface of the fixing block 22. A bidirectional lead screw 23 is connected to the gas branch pipe 11. A knob 24 is fixedly connected to one end of the bidirectional lead screw 23. A movable block 26 is threadedly connected to the surface of the bidirectional lead screw 23. An adjusting rod 27 is rotatably connected to the surface of the movable block 26. A connecting rod 29 is fixedly connected to the surface of the connecting rod 29. A connecting block 28 is fixedly connected to the surface of the adjusting rod 27 away from the movable block 26. A guide rod 25 is fixedly connected to the surface of the gas main pipe 1. The guide rod 25 slides on the surface of the connecting rod 29. This installation mechanism can simultaneously install multiple sets of gas branch pipes 11 onto the flame burners 12, and can also simultaneously remove multiple sets of flame burners 12 from the gas branch pipes 11, thereby improving the maintenance efficiency of maintenance personnel for the gas main pipe 1 and the gas branch pipes 11. The interior of the gas branch pipes 11 needs to be regularly maintained and cleaned.

[0025] Furthermore, a first support block 3 is fixedly connected to the surface of the gas main pipe 1, and a first support screw 31 is threadedly connected to the surface of the first support block 3. A second support block 32 is fixedly connected to the surface of the air main pipe 13, and a second support screw 33 is threadedly connected to the surface of the second support block 32. The gas main pipe 1 and the air main pipe 13 require support devices during installation. The first support block 3, the first support screw 31, the second support block 32, and the second support screw 33 can adjust the support height of the gas main pipe 1 and the air main pipe 13, making the installation of the gas main pipe 1 and the air main pipe 13 simpler and more convenient.

[0026] Furthermore, multiple sets of connecting pipe 2 and gas branch pipe 11 are provided and correspond to each other. A insertion groove is opened on the surface of connecting pipe 2, and sealing ring 21 is fixedly connected to the insertion groove of connecting pipe 2. Gas branch pipe 11 presses the sealing ring 21 on the insertion groove of connecting pipe 2. Gas branch pipe 11 achieves a seal between gas branch pipe 11 and connecting pipe 2 by pressing sealing ring 21, so that gas main pipe 1 outputs gas to gas branch pipe 11 through connecting pipe 2.

[0027] Furthermore, the movable block 26 has guide holes and threaded holes on its surface. The movable block 26 slides on the surface of the gas main pipe 1 through the guide holes. The bidirectional lead screw 23 is threadedly connected to the threaded hole of the movable block 26. The bidirectional lead screw 23 drives the movable block 26 to slide on the surface of the gas main pipe 1 by rotation. There are two sets of movable blocks 26, and the sliding directions of the two sets of movable blocks 26 are opposite. After the bidirectional lead screw 23 has rotated, it will restrict the position of the movable block 26 on the surface of the gas main pipe 1. During the movement, the movable block 26 will drive the adjusting rod 27 to rotate synchronously.

[0028] Furthermore, the connecting rod 29 is fixedly connected between multiple sets of gas branch pipes 11, ensuring the stability between the multiple sets of gas branch pipes 11. A guide hole is opened on the surface of the connecting rod 29, and the guide rod 25 slides on the guide hole of the connecting rod 29. The gas main pipe 1 slides on one side of the connecting rod 29 through the guide rod 25. There are two sets of guide rods 25. Under the guidance of the connecting rod 29, the gas main pipe 1 and the guide rod 25 can slide horizontally, thereby realizing the separation and installation of the gas main pipe 1 and the gas branch pipes 11. During the sliding process, the movable block 26 pushes the gas main pipe 1 and the guide rod 25 to slide on one side of the connecting rod 29 through the adjusting rod 27 and the connecting block 28. During the sliding process, the guide rod 25 and the gas main pipe 1 change the horizontal distance between the gas main pipe 1 and the gas branch pipes 11.

[0029] Furthermore, multiple sets of first support blocks 3 are provided and evenly distributed on the surface of the gas main pipe 1. Threaded holes are opened on the surface of the first support blocks 3, and the first support screw 31 is threadedly connected to the threaded holes of the first support blocks 3. The first support screw 31 moves up and down on the first support blocks 3 by rotation. Two sets of first support screws 31 are provided on the first support blocks 3 and are symmetrically distributed. The first support screws 31 can provide stable and effective support for the gas main pipe 1 through the first support blocks 3.

[0030] Furthermore, multiple sets of second support blocks 32 are provided and evenly distributed on the surface of the air main pipe 13. Threaded holes are opened on the surface of the second support blocks 32, and the second support screws 33 are threadedly connected to the threaded holes of the second support blocks 32. The second support screws 33 move up and down on the second support blocks 32 by rotation. Two sets of second support screws 33 are provided on the second support blocks 32 and are symmetrically distributed. The second support screws 33 can provide stable and effective support for the air main pipe 13 through the second support blocks 32.

[0031] Working principle: When performing internal maintenance on the gas main pipe 1 and gas branch pipe 11, it is necessary to disconnect the connection between the gas main pipe 1 and gas branch pipe 11. Rotate the knob 24 on the surface of the fixed block 22. The knob 24 drives the double-acting screw 23 to rotate. The double-acting screw 23 drives the movable block 26 to slide on the surface of the gas main pipe 1 through rotation. During the sliding process, the movable block 26 drives the adjusting rod 27 to rotate. During the rotation of the adjusting rod 27, it pushes the gas main pipe 1 and the connecting rod 29 through the movable block 26 and the connecting block 28. The distance between the gas main pipe 1 and the gas branch pipe 11 is increased, allowing the guide rod 25 to slide on the guide hole of the connecting rod 29. This changes the distance between the gas main pipe 1 and the gas branch pipe 11, causing the gas branch pipe 11 to detach from the insertion slot of the connecting pipe 2. This allows multiple sets of gas branch pipes 11 to be disassembled on the gas main pipe 1 at the same time. Similarly, multiple sets of gas branch pipes 11 can be installed on the gas main pipe 1 at the same time. By simultaneously installing and disassembling multiple sets of gas branch pipes 11 on the gas main pipe 1, the maintenance efficiency of maintenance personnel for the gas main pipe 1 and the gas branch pipes 11 is improved.

[0032] When installing the gas main pipe 1 and the air main pipe 13, the first support screw 31 is rotated on the surface of the first support block 3. When the first support screw 31 contacts the mounting surface, it supports the gas main pipe 1 through the first support block 3. The second support screw 33 is rotated on the surface of the second support block 32. When the second support screw 33 contacts the mounting surface, it supports the air main pipe 13 through the second support block 32. No separate support device is needed, making the installation of the gas main pipe 1 and the air main pipe 13 simpler and more convenient.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
