Abstract
Description
Technical Field
[0001] This utility model relates to the field of ignition connection tube technology, and in particular to a safety protection component for ignition connection tubes. Background Technology
[0002] In a burner, the ignition connection pipe is used to connect the igniter and the burner, transmitting ignition energy to ignite the fuel inside the burner. In a gas burner, if gas flows back through the ignition connection pipe, it may accumulate near the igniter or in other non-combustion areas. When the accumulated gas reaches a certain concentration, it can cause an explosion or fire when it encounters an open flame or electric spark. Therefore, a safety protection component for the ignition connection pipe is required.
[0003] When the industrial burner is started, a secure and tightly connected ignition connection tube is installed. One end is connected to the igniter, and the other end is connected to a specific ignition zone of the burner. When the electric igniter is working, the high voltage is transmitted to the ignition end through the conductive line inside the tube. The insulation layer prevents leakage. In the flame ignition mode, the tube guides the ignition source to the fuel injection zone.
[0004] In existing technologies, the internal pressure of some ignition connection pipes increases or decreases accordingly when the burner load suddenly increases or decreases during use. If the pressure change is too drastic, it will disrupt the pressure balance between the ignition connection pipe and the burner, causing combustion products or unburned fuel to flow back through the ignition connection pipe. This backflow of combustion products will contaminate the ignition connection pipe and reduce the performance of the igniter. Therefore, to address these shortcomings, an ignition connection pipe safety protection component is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a safety protection component for ignition connection pipes, which aims to improve the problem in the prior art where backflow occurs and affects the performance of some ignition connection pipes during use due to changes in gas pressure.

Detailed Implementation
[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an ignition connection tube safety protection assembly, including an ignition connection tube housing 1, which is used to connect an igniter and a burner. A protective cylinder 2 is fixedly connected to the bottom side of the ignition connection tube housing 1 by welding, thus providing support for the protective cylinder 2. A connecting ring 3 is fixedly connected to the inner wall of the protective cylinder 2, also by welding, thus providing support for the connecting ring 3. Positioning posts 4 are fixedly connected to all four sides of the bottom side of the connecting ring 3 by welding, thus providing support for the positioning posts 4. A spring 5 is sleeved on the outside of the positioning posts 4, allowing the spring 5 to be evenly stressed by restricting its movement. A disc 6 is fixedly connected to the bottom side of the positioning posts 4, providing support for the spring 5. The bottom end of the spring 5 is fixedly connected to the top side of the disc 6 by welding, allowing the spring 5 to be evenly stressed.
[0034] A sliding plate 7 is slidably connected to the outside of the positioning post 4. The positioning post 4 restricts the sliding plate 7, allowing it to slide stably and vertically. The top of a spring 5 is fixedly connected to the bottom of the sliding plate 7. As the sliding plate 7 slides, it compresses the spring 5, allowing it to store elastic potential energy and thus apply a force in the opposite direction to the sliding plate 7 for resetting. A sealing sleeve 8 is fixedly connected to the bottom of the connecting ring 3 to provide the resetting effect; it is also made of protective rubber. Anti-backflow discs 9 are fixedly connected to adjacent sides of the multiple sliding plates 7, driving the multiple sliding plates 7 to slide synchronously. The top of the anti-backflow disc 9 contacts the inside of the sealing sleeve 8, ensuring a tight fit and preventing flame backflow that could degrade performance. The top side of the anti-backflow disc 9 contacts the bottom side of the connecting ring 3, preventing flame from passing through the connecting ring 3.
[0035] A fixed cylinder 10 is fixedly connected to the top side of the ignition connection tube housing 1 by welding, thus providing support for the fixed cylinder 10. An igniter tube 11 is slidably connected inside the fixed cylinder 10 to introduce ignition-supporting material into the interior of the ignition connection tube housing 1. A sealing ring 12 is fixedly connected to the outside of the igniter tube 11 by welding, thus providing support for the sealing ring 12. A transmission assembly is slidably connected to the outside of the fixed cylinder 10, allowing it to slide stably due to the constraint of the fixed cylinder 10. The transmission assembly includes a sliding ring 14, the inner wall of which is slidably connected to the outside of the fixed cylinder 10, allowing it to slide vertically due to the constraint of the fixed cylinder 10. Limit openings 13, which are square, are provided on both the left and right sides of the fixed cylinder 10. Transmission blocks 15 are fixedly connected to the left and right sides of the inside of the sliding ring 14, driving the two transmission blocks 15 to slide synchronously. The transmission block 15 is externally slidably connected to the inside of the limiting opening 13. The limiting opening 13 restricts the transmission block 15 so that it can slide stably.
[0036] Springs 16 are fixedly connected to both ends of the bottom side of the transmission assembly. The bottom ends of the two springs 16 are fixedly connected to the inner walls of the left and right ends of the fixed cylinder 10, respectively, and are fixed by welding to ensure that the springs 16 are evenly stressed. The bottom side of the transmission block 15 is fixedly connected to the top of the springs 16. During the sliding process, the transmission block 15 compresses the springs 16, allowing the springs 16 to store elastic potential energy, which then provides the transmission block 15 with a force in the opposite direction for resetting. A sealing ring 17 is fixedly connected inside the transmission assembly. The adjacent sides of the two transmission blocks 15 are fixedly connected to the left and right sides of the sealing ring 17, respectively, and the transmission blocks 15 drive the sealing ring 17 to slide synchronously. Diamond plates 18 are slidably connected to both ends of the fixed cylinder 10. The fixed cylinder 10 restricts the diamond plates 18 to remain stable. Two rhomboid plates 18 are slidably connected at their adjacent ends to the left and right ends of the igniter tube 11, respectively, thus fixing the igniter tube 11. The two rhomboid plates 18 are slidably connected at their distal ends to the left and right sides of the inner wall of the sliding ring 14, respectively, allowing the rhomboid plates 18 to slide horizontally by the sliding ring 14 against them. Square plates 19 are fixedly connected to the front and rear sides of the rhomboid plates 18, restricting their movement and preventing them from slipping. Cavities 20 are provided at both the left and right ends of the top of the fixing cylinder 10, providing space for the rhomboid plates 18 and the square plates 19 to move.
[0037] Working principle: The ignition source is directed through the ignition connecting tube housing 1 via the ignition tube 11. Simultaneously, the internal pressure pushes the anti-backflow disc 9 to slide, which in turn drives multiple sliding plates 7 to slide and compress the spring 5. This allows the spring 5 to store elastic potential energy, which is then used by the sliding plates 7 to give the anti-backflow disc 9 a reverse force to reset and press against the anti-backflow disc 9. When the ignition source is not being directed, there is no air pressure inside the ignition connecting tube housing 1. The force of the spring 5's reset is transmitted to the anti-backflow disc 9 through the sliding plates 7, allowing the anti-backflow disc 9 to fit against the sealing sleeve 8, preventing the flame from burning inside the ignition connecting tube housing 1, thus achieving the anti-backflow effect and preventing the performance of the ignition connecting tube housing 1 from deteriorating, thereby achieving a protective effect.
[0038] During the installation of the igniter tube 11, the sliding ring 14 is pushed downwards, which in turn drives the transmission block 15 to slide and compress the second spring 16. This allows the second spring 16 to store elastic potential energy, which in turn provides a force in the opposite direction to the sliding ring 14 via the transmission block 15 to reset it. As the sealing ring 17 slides, it slides until it no longer presses against the rhomboid plate 18. At this point, the igniter tube 11 can be pushed into the interior of the ignition connection tube housing 1, while simultaneously pressing against the two rhomboid plates 18 and sliding them to opposite sides. When the installation is complete, the tension on the sliding ring 14 is released. The reset force of the second spring 16 then pushes the sliding ring 14 back to its original position via the transmission block 15, pressing against the two rhomboid plates 18. This allows the two rhomboid plates 18 to slide into the interior of the igniter tube 11, thus quickly completing the installation and improving work efficiency. During the sliding of the transmission block 15, the sealing ring 17 is also reset and pressed against the sealing ring 12, achieving a sealing effect.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
