Description

Technical Field

[0001] This utility model relates to the field of igniter technology, specifically to an ignition device for an intermediate bread baker. Background Technology

[0002] In the continuous casting steel production process of the metallurgical industry, the tundish plays multiple core functions. The tundish not only stabilizes the steel flow, effectively reducing the scouring force of the steel flow on the primary billet shell in the crystallizer, but also stores molten steel, ensuring the uniformity of its temperature. Simultaneously, the tundish has the ability to separate floating non-metallic inclusions. In multi-strand continuous casting machines, it can also precisely distribute molten steel to each crystallizer, achieving a flow distribution function. Furthermore, in the critical process of changing ladles, the tundish ensures the continuity of multi-heat continuous casting operations, which is of great significance to the stability of the entire production process.

[0003] To ensure the tundish meets production requirements, a baking oven fueled by coal gas and compressed air is typically used for baking. Depending on the tundish's volume, the baking oven is usually equipped with 2-8 burners. The baking effect of the tundish directly affects the quality of the cast billet, production continuity, and safe operation; therefore, efficient and stable baking is crucial.

[0004] Currently, multiple burners are typically ignited simultaneously using electronic igniters. However, despite their high degree of automation, electronic igniters rely on arc generating devices and control circuits. Damage to circuits or capacitors requires repair time and is prone to aging, exhibiting instability during power outages or in humid environments. Therefore, it is necessary to have a handheld ignition device as a backup.

[0005] Currently, electronic igniters are commonly used in production to simultaneously ignite multiple burners. While this method offers the advantage of high automation, it also has significant drawbacks. Electronic igniters are highly dependent on the arc generating device and control circuitry. If the circuitry or capacitors fail, repairs are time-consuming, and the components are prone to aging. Their stability is also severely affected during power outages or in humid environments. Therefore, configuring a handheld ignition device as a backup is essential. However, existing handheld ignition devices are mostly independent units, requiring multiple operators to ignite the burners simultaneously due to the large number of burners. Inconsistent operator movements can easily lead to inconsistent ignition times for each burner, resulting in some gas leakage and seriously threatening the safety of the operators. Utility Model Content

[0006] To address the technical problem that existing handheld ignition devices are mostly independent and require multiple operators to ignite due to the large number of burners, which can easily lead to inconsistent ignition times for each burner due to differences in operator movements, resulting in partial gas leakage and seriously threatening the personal safety of operators, this utility model provides an ignition device for an intermediate batch baking oven.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ignition device for an intermediate bread baker includes a handle, the fixed side of which is connected to one side of a main rod, and a plurality of ignition rods are connected to the other side of the main rod. The plurality of ignition rods are spaced apart along the length of the main rod. One end of each ignition rod is connected to the main rod, and the other end extends away from the handle. The end of each ignition rod away from the handle is used to connect to an ignition element.

[0008] By adopting the above structural scheme, this application integrates multiple ignition rods into the same device. The distance between the ends of the ignition rods connected to the ignition element in the ignition device of this application is adaptively set according to the spacing of each burner. One person holds the handle and, after igniting the ignition element, simultaneously controls multiple ignition rods to align with multiple burners one by one and opens the gas valve, which can ensure that each burner can be ignited at the same time, avoiding inconsistent ignition time caused by multiple people operating separately and avoiding the risk of gas leakage.

[0009] In a preferred implementation of the ignition device for an intermediate bread baker, one end of each ignition rod connected to the main rod converges toward the midpoint of the main rod, while the other end of each ignition rod extends at an angle away from the midpoint of the main rod where it is connected to the main rod.

[0010] By adopting the above structural scheme, the length of the ignition rod can be shortened while maintaining the spacing between the ends of the ignition rods connected to the ignition components.

[0011] In a preferred embodiment of the ignition device for an intermediate bread baker, each ignition rod is connected to the same support rod, which is arranged parallel to the main rod and located between the two ends of the ignition rod.

[0012] By adopting the above structural design, the overall structural strength is enhanced, the structural stability is improved, and the shaking of the ignition rod is reduced.

[0013] In a preferred implementation of the ignition device for an intermediate bread baker, each ignition rod is connected to a clip at the end furthest from the handle, the clip being used to secure the ignition element.

[0014] With the above structural design, the clamping force of the clip can ensure that the ignition element does not fall off during the ignition process, avoiding ignition failure or safety hazards caused by the ignition element falling off. At the same time, the clip can quickly load and unload the ignition element, improving replacement efficiency.

[0015] In a preferred embodiment of the ignition device for an intermediate bread baker, the handle includes a gripping rod arranged parallel to the main rod. Both ends of the gripping rod are connected to a fixing rod, one end of which is fixedly connected to the gripping rod, and the other end of which is fixedly connected to the main rod.

[0016] With the above-mentioned structural design, the burners of the baking oven are usually arranged horizontally at the bottom of the intermediate package. Therefore, when the ignition device of this application is used, the main rod is usually in a horizontal state. The holding rod is set parallel to the main rod so that when this application is used, the holding rod is also in a horizontal state, which is conducive to the staff to grasp the holding rod and pull it up, making it convenient to apply force.

[0017] In a preferred embodiment of the ignition device for an intermediate bread baker, the length of the holding rod is shorter than that of the main rod, the midpoint of the holding rod is opposite to the midpoint of the main rod, the fixed rod is perpendicularly connected to the main rod, and both ends of the holding rod are connected to reinforcing rods. One end of the reinforcing rod is fixedly connected to the holding rod, and the other end is connected to the end of the main rod.

[0018] By adopting the above structural scheme, the end of the reinforcing rod connects the gripping rod and the main rod to form a triangular support structure, thereby improving the load-bearing capacity of this application.

[0019] In a preferred embodiment of the ignition device for an intermediate bread baker, one of the two reinforcing rods is connected to an abutment rod, one end of which is perpendicularly connected to the reinforcing rod, and the other end is connected to the side wall of the main rod.

[0020] The burners of the baking oven are usually arranged horizontally at the bottom of the intermediate ladle. Therefore, the ignition device of this application is used horizontally. That is to say, when this application is in use, the main rod is in a horizontal state. However, for convenient transportation, it usually needs to be transported vertically. With the above structural solution, when transporting the ignition device of this application vertically, the operator can hold the holding rod with one hand on top and the reinforcing rod with the other hand on the bottom. In order to facilitate the operator's hand to exert force on the reinforcing rod, the hand is held on the part of the reinforcing rod below the abutment rod. The upper part of the hand can abut against the abutment rod, and the hand can lift upward with full force. Under the obstruction of the abutment rod, the hand will not slip upward, which helps to maintain the position.

[0021] As a preferred implementation of the ignition device for an intermediate bread baker, the handle also includes a second abutment rod, which is parallel to the fixed rod and located between the two fixed rods. One end of the second abutment rod is connected to the grip rod, and the other end is connected to the main rod.

[0022] With the above-described structural design, when the ignition device of this application is transported vertically, the operator can hold the grip rod with one hand on top and the reinforcing rod with the other hand on the bottom. In order to facilitate the operator's hand to exert force on the grip rod, the hand is placed on the lower part of the grip rod of the abutment rod two, and the upper part of the hand can abut against the abutment rod two. The hand can be lifted up with full force, and the hand will not slip up under the obstruction of the abutment rod two, which is conducive to maintaining the position.

[0023] As a preferred implementation of the ignition device for an intermediate bread baker, the side wall of the grip bar is provided with anti-slip texture.

[0024] With the above structural design, the anti-slip texture increases the surface friction of the grip bar. In the high-temperature and dusty environment of the metallurgical workshop, the anti-slip texture can effectively prevent slippage caused by the accumulation of dust and oil. Even in a humid environment or when hands are sweaty, workers can still hold the grip stably.

[0025] In a preferred embodiment of the ignition device for an intermediate bread baker, the surface of the ignition rod is coated with an anti-oxidation coating.

[0026] With the above structural design, the anti-oxidation coating can resist the erosion of high-temperature flames and oxidizing atmospheres, prevent the surface of the ignition rod from oxidizing and peeling, avoid the oxide scale falling off and affecting the contact between the ignition element and the burner, ensure the continuous and stable ignition process, maintain the shape of the ignition rod, and extend the service life of the ignition rod.

[0027] The beneficial effects of this utility model include: This application integrates multiple ignition rods into one unit, changing the traditional mode of requiring multiple operators for independent ignition devices. During manufacturing, the spacing between the ends of the ignition rods connected to the ignition element in this application's ignition device is adaptively set according to the spacing of each burner, so that the end of each ignition rod connected to the ignition element can be aligned with one burner. During operation, one person holds the handle, and after igniting the ignition element, simultaneously controls multiple ignition rods to align with multiple burners one by one, and opens the gas valve, thus ensuring that all burners are ignited at the same time, avoiding inconsistent ignition times caused by multiple people operating separately, and avoiding the risk of gas leakage.

[0028] To more clearly illustrate the technical solution of this utility model, the drawings used in the description will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Reference Figure 1 This embodiment proposes an ignition device for an intermediate bread baker, including a handle 1. The fixed side of the handle 1 is connected to one side of a main rod 2, and a plurality of ignition rods 3 are connected to the other side of the main rod 2. The plurality of ignition rods 3 are spaced apart along the length of the main rod 2. One end of each ignition rod 3 is connected to the main rod 2, and the other end extends away from the handle 1. Each ignition rod 3 has a clip 6 connected to the end away from the handle 1. The clip 6 is used to fix the ignition element 4. In this embodiment, the ignition element 4 can be asbestos cloth impregnated with kerosene. The surface of each ignition rod 3 is coated with an anti-oxidation coating, which can be an alumina coating. Each ignition rod 3 is connected to the same support rod 5. The support rod 5 is arranged parallel to the main rod 2 and is located between the two ends of the ignition rod 3, which strengthens the overall structural strength, enhances structural stability, reduces the shaking of the ignition rod 3, and improves ignition stability. One end of each ignition rod 3 that is connected to the main rod 2 converges towards the midpoint of the main rod 2, and the other end of each ignition rod 3 that is connected to the main rod 2 extends at an angle away from the midpoint of the main rod 2. This can both shorten the length of the ignition rod 3 and maintain the distance between the ends of each ignition rod 3 that are connected to the ignition element 4.

[0033] The burners of the baking oven are usually arranged horizontally at the bottom of the intermediate bun; therefore, the ignition device proposed in this embodiment is for horizontal use, meaning that the main rod 2 is in a horizontal state during use. However, for ease of transportation, vertical transport is usually required. Figure 1 This describes the state of the ignition device during vertical transport in this embodiment.

[0034] In this embodiment, the handle 1 includes a grip rod 11, and the side wall of the grip rod 11 is provided with anti-slip texture. The anti-slip texture can be... Figure 1The mesh pattern is shown. The grip rod 11 is shorter than the main rod 2, and is parallel to the main rod 2. The midpoint of the grip rod 11 is opposite to the midpoint of the main rod 2. Both ends of the grip rod 11 are connected to fixed rods 12, which are perpendicular to the main rod 2. One end of the fixed rod 12 is fixedly connected to the grip rod 11, and the other end is fixedly connected to the main rod 2. Both ends of the grip rod 11 are connected to reinforcing rods 13. One end of the reinforcing rod 13 is fixedly connected to the grip rod 11, and the other end is connected to the end of the main rod 2. One of the two reinforcing rods 13 is connected to an abutment rod 14. One end of the abutment rod 14 is perpendicularly connected to the reinforcing rod 13, and the other end is connected to the side wall of the main rod 2. The handle 1 also includes a second abutment rod 15, which is parallel to the fixed rod 12 and located between the two fixed rods 12. One end of the second abutment rod 15 is connected to the grip rod 11, and the other end is connected to the main rod 2.

[0035] Work process: First, based on the number and distribution spacing of the burners in the intermediate batch oven, the ignition device is designed and manufactured accordingly. Specifically, the number of ignition rods 3 is set according to the number of burners, and the distance between the ends of the ignition rods 3 connected to the ignition element 4 is adjusted according to the spacing of each burner, so that the end of each ignition rod 3 connected to the ignition element 4 can be aligned with the burner.

[0036] Asbestos cloth soaked in kerosene is used as the ignition element 4 and is fixed by the clip 6 at the end of the ignition rod 3. The clamping structure of the clip 6 ensures that the asbestos cloth does not fall off during the ignition process, and can be quickly installed and removed to meet the needs of multiple ignitions.

[0037] Check if the anti-oxidation coating on the surface of the ignition rod 3 is intact to ensure that it can withstand the high temperature flame of over 1000℃ inside the oven; at the same time, confirm that the anti-slip texture on the side wall of the handle 1 grip rod 11 is free of dust and oil accumulation to ensure grip stability.

[0038] With the main rod 2 in a horizontal position, one operator holds the handle rod 11 with one or both hands, while another operator uses a lighter or ignition gun to ignite the asbestos cloth at the end of each ignition rod 3, ensuring that all ignition elements 4 form a stable flame.

[0039] Hold the gripping rod 11 horizontally so that the main rod 2 is aligned with the horizontal arrangement of the burners at the bottom of the intermediate package. Move the entire device so that the ignition element 4 at the end of each ignition rod 3 is aligned with the corresponding burner.

[0040] After confirming that all ignition elements 4 are aligned with the burners, notify the operators in the central control room to open the gas valves. At this time, the burning asbestos cloth simultaneously ignites the gas emitted from each burner, achieving simultaneous ignition of multiple burners and avoiding the risk of gas spillage. An anti-oxidation coating prevents the ignition rod 3 from oxidizing and deforming at high temperatures.

[0041] When vertical transport devices are required, such as Figure 1 As shown, the operator holds the gripping rod 11 below the abutment rod 2 15 with one hand and the reinforcing rod 13 below the abutment rod 14 with the other hand. Both the abutment rod 14 and the abutment rod 2 15 can prevent the hand from sliding upwards, ensuring that the direction of force applied by the hand is stable when gripping.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
