Description

Technical Field

[0001] This utility model relates to the field of ignition device technology, specifically to a special ignition gun for coke oven riser pipes. Background Technology

[0002] Coke oven riser pipes are typically used for the emission and recovery of coke oven fuel gas. Ignition is used to ensure that the gas inside the riser pipe can be ignited smoothly and to maintain a certain temperature and pressure to ensure the normal operation of the coke oven.

[0003] For example, the national authorized patent announcement number CN218721659U discloses an ignition device for a coke oven riser pipe, belonging to the field of environmental protection equipment technology. The coke oven riser pipe includes a riser pipe body, and a riser pipe cover is installed at the top opening of the riser pipe body. A pull rod is provided on the riser pipe cover. The ignition device is characterized by including an ignition rod located directly above the riser pipe cover; the ignition rod is fixedly connected to the riser pipe body via a bracket; and the ignition rod is connected to a switch located on the outside of the riser pipe body via a cable. This invention can instantly ignite combustible gas after the riser pipe cover is opened, and can instantly ignite vented gas when the pressure in the gas collecting pipe suddenly increases and the riser pipe vents, avoiding environmental accidents. This invention has the advantages of simple structure and convenient operation.

[0004] However, the ceramic ignition needle used in the coke oven riser pipe ignition device mentioned above cannot separate the flame source from the ceramic ignition needle after igniting the gas discharged from the riser pipe. This causes the ceramic ignition needle to be constantly exposed to high temperatures. Although ceramic materials have a certain degree of high temperature resistance, their performance will deteriorate and their service life will be reduced when exposed to high temperatures for a long time. Utility Model Content

[0005] The purpose of this invention is to provide a special ignition gun for coke oven riser pipes, in order to solve the problem mentioned in the background art that the use of ceramic ignition needles to ignite the gas discharged from the riser pipe cannot separate the fire source from the ceramic ignition needle.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A special ignition gun for coke oven riser pipe includes: a riser pipe body, a docking plate fixedly installed at one end of the outer surface of the riser pipe body, a connecting plate rotatably installed inside the docking plate, a top cover fixedly installed at one end of the connecting plate, and an arc ignition shielding mechanism slidably installed inside the riser pipe body, with the arc ignition end of the arc ignition shielding mechanism installed on the outer surface of the riser pipe body.

[0008] Preferably, a first mounting plate is fixedly installed on the outer surface of the riser tube body, and a photoelectric sensor is fixedly installed on the upper surface of the first mounting plate. The photoelectric sensor is flush with the connecting plate. When the connecting plate drives the top cover to flip open from the upper surface of the riser tube body, the amount of light reflection will change, so that the photoelectric sensor can detect the change in light intensity and thus know the flipped state of the top cover.

[0009] Preferably, the signal transmitting end of the photoelectric sensor is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the arc ignition shielding mechanism. A support rod is fixedly installed on the outer surface of the riser body, and a first electric push rod is rotatably installed inside the support rod. The piston rod of the first electric push rod is rotatably installed at one end of the connecting plate.

[0010] Preferably, the photoelectric sensor detects that after the top cover flips, it sends a signal to the controller, which then controls the arc ignition shielding mechanism to perform arc ignition and ignite the combustible gas in the riser body.

[0011] Preferably, the arc ignition shielding mechanism includes a convex heat insulation cylinder, which is slidably installed inside the riser tube body and can shield the first arc conductive rod of the three sets of arc generators and the second arc conductive rod installed on the inner wall surface of the riser tube body. The arc generators are fixedly installed on the outer surface of the riser tube body.

[0012] Preferably, during the process of generating an electric arc, all three sets of electric arc generators are attracted by the second electric arc conductive rods at both ends, thereby guiding the generated electric arc into a ring shape from which combustible gas is discharged and ignited.

[0013] Preferably, a lifting plate is fixedly installed on the outer surface of the convex heat insulation cylinder. The lifting plate slides out from the sliding port, which is located on the outer surface of the riser tube body. The lower surface of the lifting plate is fixedly connected to the piston rod of the second electric push rod. The second electric push rod is fixedly installed on the upper surface of the second mounting plate, and the second mounting plate is fixedly installed on the outer surface of the riser tube body.

[0014] Preferably, the second electric push rod and the arc generator are both controlled by a controller, and the controller and the photoelectric sensor are model E3Z and E3JK, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the design of the riser body, top cover, connecting plate, first electric push rod, photoelectric sensor, and arc ignition shielding mechanism, when the combustible gas inside the riser body is ignited, the connecting plate at one end of the piston rod can be flipped within the docking plate by activating the first electric push rod. This allows the docking plate to cause the top cover to flip open from the upper surface of the riser body. During the flipping process of the connecting plate by the first electric push rod, the amount of light reflection changes, which allows the photoelectric sensor at the lower end of the connecting plate to detect the change in light intensity, thus determining the flipping state of the top cover. The photoelectric sensor can then send a signal to the controller, which will control the shielding end in the arc ignition shielding mechanism to slide down from the periphery of the arc ignition end, exposing the arc ignition end. This allows the arc ignition end to form a circular electric ring within the riser tube, enabling combustible gas to be discharged and ignited. After the circular electric ring is maintained for several seconds, the controller will close the arc ignition end and raise the cover end to protect the arc ignition end. This prevents the arc ignition end from being continuously exposed to high temperatures, significantly extending its service life. High temperatures cause cumulative damage to equipment, and continuous high temperatures can degrade the material properties of the arc ignition end, such as electrode corrosion and aging of insulation materials. This control method reduces the high-temperature exposure time, lowers the frequency of equipment maintenance and replacement, and saves equipment maintenance costs. The ignited combustible gas will be discharged from the center of the cover end.

[0017] 2. Through the design of the arc generator, convex heat insulation cylinder, lifting plate, and second electric push rod, after the photoelectric sensor detects the flipping state of the top cover, it can send a signal to the controller. The controller will then control the second electric push rod to pull the piston rod and start the arc generator to generate an arc through the first arc conductive rod. The pulled piston rod will then pull down the lifting plate, causing the convex heat insulation cylinder to slide down within the riser tube body. This allows the convex heat insulation cylinder to detach from the enclosure of the first and second arc conductive rods of the arc generator, exposing it. The arc generated by the first arc conductive rod will be attracted by the second arc conductive rods at both ends, thus guiding the generated arc into a ring shape for the combustible gas to pass through. The ignited gas is discharged and then ignited. After a few seconds, the controller shuts off the arc generator and restarts the second electric push rod to push the piston rod. This allows the second electric push rod to push the sliding convex heat insulation cylinder back up, so that the raised convex heat insulation cylinder once again surrounds the first and second arc conductive rods. This prevents the first and second arc conductive rods from being continuously exposed to high temperatures, helps extend the service life of the arc generator's conductive rods, and reduces equipment wear. The ignited combustible gas is discharged from the center of the convex heat insulation cylinder. This achieves automatic arc generation to ignite combustible gas during the opening of the top cover, reducing the need for human intervention. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] like Figures 1-3 As shown, the coke oven riser pipe special ignition gun includes: a riser pipe body 1, a docking plate 101 fixedly installed at one end of the outer surface of the riser pipe body 1, a connecting plate 103 rotatably installed inside the docking plate 101, a top cover 102 fixedly installed at one end of the connecting plate 103, and an arc ignition shielding mechanism 2 slidably installed inside the riser pipe body 1, with the arc ignition end of the arc ignition shielding mechanism 2 installed on the outer surface of the riser pipe body 1.

[0027] A first mounting plate 108 is fixedly installed on the outer surface of the riser tube body 1. A photoelectric sensor 109 is fixedly installed on the upper surface of the first mounting plate 108. The photoelectric sensor 109 is flush with the connecting plate 103. When the connecting plate 103 drives the top cover 102 to flip open from the upper surface of the riser tube body 1, the amount of light reflection will change, so that the photoelectric sensor 109 can detect the change in light intensity and thus know the flipped state of the top cover 102.

[0028] The signal transmitting end of the photoelectric sensor 109 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the arc ignition shielding mechanism 2. A support rod 104 is fixedly installed on the outer surface of the riser body 1, and a first electric push rod 105 is rotatably installed inside the support rod 104. The piston rod of the first electric push rod 105 is rotatably installed at one end of the connecting plate 103.

[0029] When the photoelectric sensor 109 detects that the top cover 102 has flipped, it sends a signal to the controller, which then controls the arc ignition shielding mechanism 2 to perform arc ignition and ignite the combustible gas in the riser body 1.

[0030] Through the design of the riser body 1, top cover 102, connecting plate 103, first electric push rod 105, photoelectric sensor 109, and arc ignition shielding mechanism 2, when the combustible gas in the riser body 1 is ignited, the connecting plate 103 at one end of the piston rod can be flipped within the docking plate 101 by activating the first electric push rod 105. This allows the docking plate 101 to cause the top cover 102 to flip open from the upper surface of the riser body 1. During the flipping process of the connecting plate 103 by the first electric push rod 105, the amount of light reflection changes, which allows the photoelectric sensor 109 at the lower end of the connecting plate 103 to detect the change in light intensity, thereby determining the flipping state of the top cover 102. The photoelectric sensor 109 can then send a signal to the controller, which will then control the arc ignition shielding mechanism 2. The cover end slides down from the periphery of the arc ignition end to expose it, thus forming a circular electric ring within the riser tube body 1. This allows combustible gas to be discharged and ignited. After the circular electric ring is maintained for several seconds, the controller closes the arc ignition end and raises the cover end to protect it. This prevents the arc ignition end from being continuously exposed to high temperatures, significantly extending its service life. High temperatures cause cumulative damage to equipment, and continuous high temperatures can degrade the material properties of the arc ignition end, such as electrode corrosion and aging of insulation materials. This control method reduces the high-temperature exposure time, lowers the frequency of equipment maintenance and replacement, and saves on equipment maintenance costs. The ignited combustible gas is discharged from the center of the cover end.

[0031] like Figures 4-5As shown, the arc ignition shielding mechanism 2 includes a convex heat insulation cylinder 204. The convex heat insulation cylinder 204 is slidably installed inside the riser body 1 and can shield the first arc conductive rod 202 of the three sets of arc generators 201 and the second arc conductive rod 203 installed on the inner wall surface of the riser body 1. The arc generators 201 are fixedly installed on the outer surface of the riser body 1.

[0032] During the process of generating an electric arc, the three sets of electric arc generators 201 are all attracted by the second electric arc conductive rods 203 at both ends, so that the generated electric arc is guided into a ring shape for the combustible gas to be discharged from and ignited.

[0033] A lifting plate 205 is fixedly installed on the outer surface of the convex heat insulation cylinder 204. The lifting plate 205 slides out from the sliding port 107, which is located on the outer surface of the riser body 1. The lower surface of the lifting plate 205 is fixedly connected to the piston rod of the second electric push rod 206. The second electric push rod 206 is fixedly installed on the upper surface of the second mounting plate 106, which is also fixedly installed on the outer surface of the riser body 1.

[0034] The second electric push rod 206 and the arc generator 201 are both controlled by the controller, and the controller and the photoelectric sensor 109 are model E3Z and E3JK, respectively.

[0035] Through the design of the arc generator 201, the convex heat insulation cylinder 204, the lifting plate 205, and the second electric push rod 206, after the photoelectric sensor 109 detects the flipped state of the top cover 102, it can send a signal to the controller. The controller will then control the second electric push rod 206 to pull the piston rod and start the arc generator 201 to generate an arc through the first arc conductive rod 202. The pulled piston rod will then pull down the lifting plate 205, causing the convex heat insulation cylinder 204 to slide down inside the riser body 1. This allows the convex heat insulation cylinder 204 to detach from the enclosure of the first arc conductive rod 202 and the second arc conductive rod 203 of the arc generator 201, exposing it. The arc generated by the first arc conductive rod 202 will be attracted by the second arc conductive rods 203 at both ends, thus guiding the generated arc into a circular shape. The annular ring allows combustible gas to be discharged and ignited. After the circular ring is maintained for several seconds, the controller shuts off the arc generator 201 and restarts the second electric push rod 206 to push the piston rod. This allows the second electric push rod 206 to push the sliding convex heat insulation cylinder 204 back up, so that the raised convex heat insulation cylinder 204 once again surrounds the first arc conductive rod 202 and the second arc conductive rod 203. This prevents the first arc conductive rod 202 and the second arc conductive rod 203 from being continuously exposed to high temperatures, which helps to extend the service life of the conductive rods of the arc generator 201 and reduce equipment wear. The ignited combustible gas is discharged from the center of the convex heat insulation cylinder 204. This achieves automatic generation of an arc to ignite the combustible gas during the opening of the top cover 102, reducing the need for human intervention.

[0036] Based on the above technical solution, the working steps of this solution are summarized as follows: When the heatable gas inside the riser body 1 is ignited, the connecting plate 103 at one end of the piston rod can be flipped within the docking plate 101 by activating the first electric push rod 105. This allows the docking plate 101 to cause the top cover 102 to flip open from the upper surface of the riser body 1. During the flipping process of the connecting plate 103 by the first electric push rod 105, the amount of light reflection will change, allowing the photoelectric sensor 109 at the lower end of the connecting plate 103 to detect the change in light intensity, thereby determining the flipping state of the top cover 102. The photoelectric sensor 109 can then send a signal to the controller, which will control the second electric push rod 206 to pull the piston rod and activate the arc generator 201 to generate an arc through the first arc conductive rod 202. The pulled piston rod will then pull down the lifting plate 205, causing the convex heat insulation cylinder 204 to slide down inside the riser body 1, thereby allowing the convex heat insulation cylinder 204 to detach from the arc generator 201. The first arc-conducting rod 202 and the second arc-conducting rod 203 of the 01 are exposed to the environment. The arc generated by the first arc-conducting rod 202 is attracted by the second arc-conducting rods 203 at both ends, so that the generated arc is guided into a ring shape for the combustible gas to be discharged and ignited. After the circular ring is maintained for a few seconds, the controller will shut off the arc generator 201 and restart the second electric push rod 206 to push the piston rod. This allows the second electric push rod 206 to push the sliding convex heat insulation cylinder 204 up again, so that the raised convex heat insulation cylinder 204 once again surrounds the first arc-conducting rod 202 and the second arc-conducting rod 203. This prevents the first arc-conducting rod 202 and the second arc-conducting rod 203 from being exposed to high temperature. The ignited combustible gas will be discharged from the center of the convex heat insulation cylinder 204. This achieves automatic generation of an arc to ignite the combustible gas during the opening of the top cover 102, reducing the need for human intervention.

[0037] In summary, after the coke oven riser pipe igniter ignites the combustible gas, it can automatically enclose the first arc conductive rod 202 and the second arc conductive rod 203 that generate the electric arc within the convex heat insulation cylinder 204, separating them from the fire source. This prevents the first arc conductive rod 202 and the second arc conductive rod 203 from being continuously exposed to high temperatures, helps extend the service life of the conductive rods of the arc generator 201, and reduces equipment wear and tear.
