Description

An integrated ignition gun for a torpedo can baking device Technical Field

[0001] The utility model relates to the technical field of torpedo can baking, in particular to an integrated ignition gun used in a torpedo can baking device. Background Art

[0002] The torpedo jar baking devices used in various steel mills all rely on manual torch ignition, posing a safety hazard. Manual ignition is used because the burner typically extends a long distance into the torpedo jar during baking, reaching up to three meters. During the baking process, the internal temperature of the torpedo jar is extremely high, reaching a final baking temperature of 950°C. Conventional ignition devices are incapable of operating under these conditions.

[0003] Therefore, it is necessary to design a new ignition gun structure that can overcome the problem that conventional ignition devices cannot be used in the high-temperature environment after baking in the torpedo tank. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the utility model provides an integrated ignition gun for a torpedo tank baking device, which can automatically ignite, is safer and more reliable, overcomes the problem that conventional ignition devices cannot be used under extreme working conditions such as high temperature inside a torpedo tank, and is easy to use and easy to disassemble and assemble.

[0005] In order to achieve the above-mentioned purpose, the embodiments of the present invention adopt the following technical solutions:

[0006] An integrated ignition gun for a torpedo can baking device includes a T-shaped gas pipe with an ignition hole provided thereon. The integrated ignition gun also includes a ceramic partition, a ceramic sleeve, a pressure-guiding rod, and an ignition electrode, all of which are arranged on both sides of the T-shaped gas pipe. The ceramic sleeve is fixed to the T-shaped gas pipe via the ceramic partition, and the pressure-guiding rod is sleeved within the ceramic sleeve. One end of the pressure-guiding rod is connected to the ignition electrode, and the other end is arranged on one side of the ignition hole. After the ignition electrode receives an ignition voltage signal, a spark is generated between the end of the pressure-guiding rod and the ignition hole.

[0007] According to one aspect of the present invention, the T-shaped gas pipe includes a main pipe section and a secondary pipe section, which are vertically connected, and the ignition holes are provided at both ends of the secondary pipe section.

[0008] According to one aspect of the present invention, the ceramic partition includes a first partition and a second partition, and the ceramic casing includes a main casing section and a secondary casing section, which are vertically connected. The secondary casing section is connected to the secondary casing section through the first partition, and the main casing section is connected to the main casing section through the second partition.

[0009] According to one aspect of the present invention, the first partition plate and the second partition plate are both block-shaped.

[0010] According to one aspect of the present invention, the ignition electrode is connected to an ignition transformer.

[0011] According to one aspect of the present invention, the pressure-conducting rod is provided with an external thread, and the ignition electrode is threadedly connected to the pressure-conducting rod.

[0012] According to one aspect of the present invention, the ceramic partition plate and the ceramic sleeve are both made of corundum, and the ceramic sleeve and the pressure-guiding rod are both L-shaped.

[0013] According to one aspect of the present invention, the pressure-guiding rod is made of Cr28Ni48W5 and has a diameter of 6 mm, and the inner diameter of the ceramic sleeve is 6.3 mm.

[0014] According to one aspect of the present invention, the T-shaped gas pipe is made of a DN25 stainless steel pipe.

[0015] According to one aspect of the present invention, the diameter of the ignition holes is 4.5 mm, and the total number of the ignition holes is 96.

[0016] The advantages of this utility model include: ignition gas is delivered to the ignition hole via a T-shaped gas pipe, overflowing through the ignition hole to the end of the pressure rod. The ignition electrode receives the ignition voltage signal, generating a spark between the end of the pressure rod and the ignition hole, which ignites the gas in the ignition hole area. This device eliminates the need for manual torch ignition, achieving automatic ignition and increasing safety and reliability. By integrating the integrated ignition gun into the burner air line of the torpedo tank baking device and using a high-temperature-resistant hard pressure rod and a ceramic sleeve for isolation and protection, the device avoids direct contact with the high-temperature atmosphere within the torpedo tank. This overcomes the problem of conventional high-voltage ignition cables being unable to operate in environments exceeding 75°C for long periods of time, and overcomes the problem of conventional ignition devices being unable to operate under extreme operating conditions such as the high temperatures within the torpedo tank. By connecting the pressure rod to a sensor detection system, the pressure rod also serves as an ion flame detection sensor element. By utilizing the unidirectional conductivity principle of flame, the current signal generated by the pressure rod is detected in real time to confirm the flame status of the ignition gun. This device can thus detect the presence or absence of a flame in real time. The device has a simple overall structure, is easy to assemble and disassemble, and is convenient to use.
