Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically to an automatic ignition device for exhaust gas from float glass flues. Background Technology

[0002] In the float glass production process, the management of flue gas is crucial. Due to the demands of the production process, the furnace needs to continuously burn coal gas to maintain a high-temperature environment. However, in practice, the drop in flue gas temperature often leads to incomplete combustion, resulting in a high concentration of unburned coal gas in the exhaust gas. This is particularly pronounced during furnace changeovers, significantly increasing the risk of flue gas explosions. Traditionally, these problems have relied primarily on manual furnace changeover operations and monitoring. This method is not only inefficient but also difficult to control precisely, thus failing to effectively prevent safety accidents caused by excessive coal gas content.

[0003] Existing automatic ignition devices for flue gas, while possessing automatic ignition capabilities and capable of remotely burning CO gas in the flue, effectively reducing the risk to workers directly exposed to harmful gases and high-temperature environments, fail to adequately consider ease of installation and disassembly. This results in increased workload for workers and reduced maintenance and repair efficiency during actual use.

[0004] In addition, existing flue gas venting devices require manual ignition by staff during each flame change, which not only makes it difficult to precisely control the flame size and increases the danger of operation, but also raises the risk of safety accidents.

[0005] Furthermore, existing flue gas ignition devices cannot effectively extend into and seal the flue, thus failing to automatically collect real-time data to determine whether ignition is necessary. This not only reduces the device's response efficiency but also increases the risk of safety accidents.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In response to the problems in related technologies, this utility model proposes an automatic ignition device for flue gas from float glass production lines to overcome the aforementioned technical problems in existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] An automatic ignition device for flue gas from float glass production includes several sets of refractory bricks, each set of refractory bricks having a high-alumina tube on top. The high-alumina tube has a fixing mechanism on top for fixing it inside the pipe, and the fixing mechanism has a terminal block on top. The outer circumference of the fixing mechanism has several adjusting components to accommodate pipes of different specifications. An ignition needle is installed at the bottom of the refractory bricks and inside the high-alumina tube.

[0010] Furthermore, in order to improve the reliability of the device and enhance its adaptability to high-temperature environments, the fixing mechanism and the middle position of the wiring terminals are both designed with a hollow structure.

[0011] Furthermore, to achieve the fixing and adjustment functions of the fixing mechanism for the pipeline and significantly improve the stability and reliability of the device, the fixing mechanism includes a base plate set on the top of the high-alumina pipe. A drive assembly is set on the top of the base plate, and a driven component is fitted on one side of the drive assembly. The drive assembly includes a drive shaft set inside the base plate, and a drive gear is sleeved on the outer circumference of the drive shaft at the top of the base plate. A square head is set at both the top and bottom of the drive shaft, passing through a terminal block and the base plate. A hollow groove is formed on the outer circumference of the drive shaft inside the base plate. A clamping component is set on the outer circumference of the drive shaft at the bottom of the hollow groove. The clamping component includes a component set in the middle... The bottom of the slot has a pin and a fixing rod. The outer circumference of the pin is fitted with a pawl. The top of the pawl is fitted with a mounting plate. The top and bottom of the mounting plate are connected to the terminal block and the base plate, and a limit rod is provided. The fixing rod and the limit rod are connected by a tension spring. The outer circumference of the drive shaft is fitted with a ratchet that cooperates with the pawl. The driven part includes an adjusting gear that meshes with the drive gear on one side. The bottom of the adjusting gear is fitted with an annular slider. The adjusting gear has several adjusting grooves arranged in a circle. The adjusting grooves are fitted with movable rods. The bottom of the movable rod and inside the base plate is fitted with a T-shaped plate, and one end of the T-shaped plate is fitted with an adjusting component.

[0012] Furthermore, to ensure stable and flexible fixing within pipes of different specifications and shapes, the adjustment assembly includes a mounting plate at one end of a T-shaped plate. Two sets of semi-circular movable blocks (I) are located on one side of the mounting plate, and two sets of semi-circular movable blocks (II) are located on one side of each set of semi-circular movable blocks (I). The principles of semi-circular movable blocks (I) and semi-circular movable blocks (II) are the same. T-shaped slide rails are provided on the outer circumference of each semi-circular movable block (I), and limit blocks are provided on the outer circumference of each T-shaped slide rail. A semi-circular groove that mates with the semi-circular movable block (I) is provided on one side of the mounting plate, and limit grooves that mate with the T-shaped slide rails are provided on the inner circumference of each semi-circular groove. An arc-shaped groove (I) that mates with the limit block is provided on the inner wall of each limit groove.

[0013] Furthermore, in order to achieve precise matching of various components and significantly improve the stability and operability of the entire device, a convex groove is provided on the top of the base plate to match the T-shaped plate; an arc-shaped groove is provided on the top of the base plate to match the limiting rod; and an annular slide rail is provided at the top of the base plate to match the annular slider.

[0014] Furthermore, in order to automatically determine whether the ignition device needs to be activated based on the real-time data collected, and to achieve more precise control, a set of refractory brick inner walls are equipped with thermocouple sensors and infrared gas sensors from top to bottom.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a simple structure and convenient operation. By incorporating a fixing mechanism, it can securely fix and seal the inner wall of float glass exhaust pipes of different specifications. With the synergistic action of thermocouple sensors and infrared gas sensors, the ignition needle is automatically ignited, thereby reducing the operational risks for workers. Furthermore, thanks to the adjusting components, it can be applied not only to circular pipes but also to square pipes, ensuring a more stable fixation and effectively preventing flue explosions, thus greatly improving the safety and reliability of the device.

[0017] 2. This utility model, through the setting of a fixing mechanism, allows workers to place the device into the float glass exhaust gas pipeline after assembly. By tightening the square head with a square wrench, the drive shaft rotates, driving the drive gear to rotate. The drive gear then drives the adjusting gear, causing the T-shaped plate to expand outward for a stable fixation. With the cooperation of the ratchet and pawl, the drive gear is locked, ensuring a secure fixation. When disassembly is required, simply move the limit rod to separate the pawl from the ratchet, allowing the device to be easily removed, thus achieving convenient disassembly.

[0018] 3. By setting an adjustment component, in cooperation with the fixing mechanism, when used for circular and square pipes, the T-shaped plate expands outward, pushing the semicircular movable block one and the semicircular movable block two to extend outward. The semicircular movable block one and the semicircular movable block two can automatically adjust their positions according to the shape of the inner wall of the circular or square pipe, thereby achieving the fastening effect on the pipe.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0033] According to an embodiment of the present invention, an automatic ignition device for flue gas from float glass is provided.

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-10 As shown, the automatic ignition device for float glass flue gas according to an embodiment of the present invention includes several sets of refractory bricks 1, each set of refractory bricks 1 having a high-alumina tube 3 on its top, a fixing mechanism 2 for fixing inside the pipe being provided on the top of the high-alumina tube 3, and a wiring terminal 4 being provided on the top of the fixing mechanism 2; several adjusting components 5 are provided on the outer circumference of the fixing mechanism 2 to accommodate pipes of different specifications; and an ignition needle 6 is provided at the bottom of the refractory bricks 1 and inside the high-alumina tube 3.

[0035] By utilizing the aforementioned technical solution of this utility model, the fixing mechanism 2 can be used to securely fix and seal the inner wall of float glass exhaust gas pipes of different specifications. With the synergistic action of the thermocouple sensor 9 and the infrared gas sensor 10, the ignition needle 6 is automatically ignited, thereby reducing the operational risks for workers. Furthermore, the adjusting component 5 can not only be used for circular pipes but also for securing square pipes, ensuring a more stable fixation effect and effectively preventing flue explosion accidents, thus greatly improving the safety and reliability of the device.

[0036] Specifically, the controller is equipped with a human-machine interface (HMI) and a PLC (Programmable Logic Controller). The HMI is the interface between the operator and the automation system. Its main function is to display the real-time operating status and input control commands. The PLC is used to execute specific control tasks, such as switch and sensor signal acquisition and processing.

[0037] In one embodiment, the fixing mechanism 2 and the wiring terminal 4 are both hollowed out in the middle, which not only improves the reliability of the device, but also enhances its adaptability to high-temperature environments.

[0038] In one embodiment, the fixing mechanism 2 includes a base plate 201 disposed on the top of the high-alumina tube 3. A drive assembly 202 is disposed on the top of the base plate 201. A driven member 203 is disposed on one side of the drive assembly 202. The drive assembly 202 includes a drive shaft 2021 disposed inside the base plate 201. A drive gear 2022 is sleeved on the outer circumference of the drive shaft 2021 and located at the top of the base plate 201. A square head 2023 is provided at both the end and the bottom of the drive shaft 2021, passing through the terminal block 4 and the base plate 201; a hollow groove 2025 is provided on the outer circumference of the drive shaft 2021 and inside the base plate 201; a clamping member 2024 is provided on the outer circumference of the drive shaft 2021 and at the bottom of the hollow groove 2025, the clamping member 2024 includes a pin 202401 and a fixing rod 202402 provided at the bottom of the hollow groove 2025, and the outer circumference of the pin 202401 is sleeved with... There is a pawl 202403; a mounting plate 202404 is provided on the top of the pawl 202403, and a limit rod 202405 is provided through the terminal 4 and the base plate 201 at both the top and bottom of the mounting plate 202404; the fixing rod 202402 and the limit rod 202405 are connected by a tension spring 202406; a ratchet 202407 that cooperates with the pawl 202403 is sleeved on the outer circumference of the drive shaft 2021, and the driven part is a follower. 203 includes an adjusting gear 2031 meshing with one side of the drive gear 2022, and an annular slider 2032 at the bottom of the adjusting gear 2031. The adjusting gear 2031 has several circumferentially arranged adjusting grooves 2033 inside, and a movable rod 2034 is installed inside each adjusting groove 2033. A T-shaped plate 2035 is installed at the bottom end of the movable rod 2034, located inside the base plate 201, and an adjusting component 5 is installed at one end of the T-shaped plate 2035. This not only realizes the fixing and adjusting functions of the fixing mechanism 2 for the pipeline, but also significantly improves the stability and reliability of the device.

[0039] The working principle of the fixed mechanism 2 is as follows: First, the operator places the installed automatic ignition device into the float glass flue. Then, a square wrench is used to tighten the square head 2023, causing the drive shaft 2021 to rotate. Power is transmitted to the adjusting gear 2031 through gear meshing. When the adjusting gear 2031 rotates, the movable rod 2034 moves within the adjusting groove 2033, and drives the adjusting assembly 5 to perform corresponding adjustments via the T-plate 2035. Simultaneously, the tension spring 202406 connects the fixed rod 202402 and the limit rod 202405, ensuring that the pawl 202403 always remains in contact with the ratchet 202407. When the drive shaft 2021 rotates in a predetermined direction, the pawl 202403 can slide on the tooth surface of the ratchet 202407, allowing the drive shaft 2021 to rotate smoothly. If the drive shaft 2021 attempts to rotate in the opposite direction, the pawl 202403 will engage with the teeth of the ratchet 202407, preventing the drive shaft 2021 from rotating in the opposite direction, thus achieving a one-way locking function. Therefore, once the T-plate 2035 is fixed, it can be locked using the locking element 2024. For removal or maintenance, simply move the limit lever 202405 to disengage the pawl 202403 from the ratchet 202407, and the device can be easily removed.

[0040] In one embodiment, the adjustment component 5 includes a mounting plate 501 disposed at one end of the T-shaped plate 2035. Two sets of semicircular movable blocks 502 are disposed on one side of the mounting plate 501, and two sets of semicircular movable blocks 508 are disposed on one side of each set of semicircular movable blocks 502. The semicircular movable blocks 502 and semicircular movable blocks 508 operate on the same principle. T-shaped slide rails 503 are disposed on the outer circumference of each semicircular movable block 502, and limit blocks 504 are disposed on the outer circumference of each T-shaped slide rail 503. A semicircular groove 505 is provided on one side of the mounting plate 501 to cooperate with the semicircular movable blocks 502. Limiting grooves 506 that cooperate with the T-shaped slide rails 503 are respectively provided on the inner circumference of the semicircular grooves 505. An arc-shaped groove 507 that cooperates with the limiting block 504 is provided on the inner wall of the limiting groove 506. This ensures a stable and flexible fixation within pipes of different sizes and shapes.

[0041] The specific working principle of the adjusting component 5 is as follows: When the fixing mechanism 2 is fixed, the driving T-shaped plate 2035 expands outward, causing the mounting plate 501 to expand together. At this time, the semi-circular movable block 502 slides in the semi-circular groove 505 inside the mounting plate 501, thereby automatically adjusting its position according to the inner wall shape of the circular or square pipe, ensuring that the device can stably adapt to the inner wall of pipes of different shapes and specifications.

[0042] In one embodiment, the base plate 201 has a convex groove 7 on its top that mates with the T-shaped plate 2035; an arcuate groove 8 on its top that mates with the limiting rod 202405; and an annular slide rail 11 on the top of the base plate 201 that mates with the annular slider 2032. This not only achieves precise matching of the various components but also significantly improves the stability and operability of the entire device.

[0043] In one embodiment, for refractory brick 1, a thermocouple sensor 9 and an infrared gas sensor 10 are arranged sequentially from top to bottom on the inner wall of a group of refractory bricks 1, which can automatically determine whether the ignition device needs to be activated based on the real-time collected data, thereby achieving more precise control.

[0044] It should be explained that the thermocouple sensor 9 is based on the Seebeck effect, which means that when two different metals or alloys are connected together, an electromotive force (voltage) will be generated if the temperatures at their ends are different.

[0045] The infrared gas sensor 10 detects gas concentration by utilizing the absorption characteristics of specific gases to infrared light. When infrared light passes through the gas, light of a specific wavelength is absorbed, and the gas concentration is determined by measuring the intensity of the absorbed light.

[0046] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0047] like Figures 1-10As shown, in practical applications, the controller is electrically connected to the thermocouple sensor 9 and the infrared gas sensor 10 in sequence. The operator first places the installed automatic ignition device into the float glass flue, and then uses a square wrench to tighten the square head 2023 (the specific working principle of the fixing mechanism 2 is as described above). When tightened to a certain extent, the drive shaft 2021 is locked by the action of the pawl 202403 and the ratchet 202407, thus achieving one-way locking of the automatic ignition device. Next, when the T-shaped plate 2035 expands outward (the specific working principle of the adjusting component 5 is as described above), the cooperating action of the semi-circular movable block one 502 and the semi-circular movable block two 508 allows the fixing mechanism 2 to better grip the inner wall of the pipe and adapt to inner walls of pipes of different shapes and specifications. After installation, the flue gas is detected by thermocouple sensor 9 and infrared gas sensor 10. The flue temperature and gas content data are automatically collected and fed back to the controller. The operator can input control commands through the human-machine interface of the controller to customize the minimum and maximum limits. If the value is higher than the set value, the ignition device will not be turned on during the flame change process. If the value is lower than the set value, the low voltage (400V) will be automatically boosted to a high voltage (10KV) during the flame change process, and an electric arc will be generated between the two needle poles to achieve ignition.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
