Description

Technical Field

[0001] This utility model belongs to the field of ignition burner technology, specifically relating to an ignition burner for a high-temperature and high-pressure gasification furnace. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air in a specific manner for combustion. Burners are classified into several types according to their application fields, including industrial burners, combustion engines, civil burners, and special burners. The function of a burner is to atomize a sample through flame combustion: the atomized sample liquid enters the burner, and under the influence of flame temperature and flame atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation, producing a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules.

[0003] Most existing burners use ignition electrodes for ignition. Ignition electrodes are usually placed near the gas outlet where the fuel is injected. Once the gas is ignited, the ignition electrode is always in the flame. If the ignition electrode is in the flame or at a high temperature for a long time, its service life will be affected.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an ignition burner for a high-temperature and high-pressure gasification furnace.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an ignition burner for a high-temperature and high-pressure gasification furnace, which can solve the problem that the ignition electrode of the existing burner is in the flame or at a high temperature for a long time, which affects its service life.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] An ignition burner for a high-temperature and high-pressure gasification furnace includes: a support, a combustion hood, and an ignition device.

[0009] A gas supply pipe is installed on the support, and multiple first gas outlet holes are equally spaced on the front section of the support. The combustion hood is installed at the end of the gas supply pipe near the first gas outlet holes, and multiple second gas outlet holes are equally spaced on the combustion hood.

[0010] The ignition device is mounted on a support and includes a housing, a first slide rod, a second slide rod, and a pushing mechanism. The housing is fixed to the side wall of the support away from the combustion hood. Both the first and second slide rods slide on the support, with their ends near the housing located inside the housing, and their other ends fixed with an ignition electrode. A fixing head is fixed to the end of each of the first and second slide rods located inside the housing. A connecting member is fixed to the first slide rod inside the housing, and the second slide rod slides on the connecting member. A first spring is installed between the connecting member and the support, and a second spring is installed between the fixing head at the tail end of the second slide rod and the connecting member. The pushing mechanism is mounted and slides on the housing and is used to push the first and second slide rods towards the combustion hood.

[0011] In one embodiment of this invention, a limiting ring is fixed to one end of the gas supply pipe near the support of the combustion hood. The limiting ring is used to limit the installation position of the combustion hood.

[0012] In one embodiment of this utility model, a threaded head is fixed to one end of the gas supply pipe near the combustion hood, and a locking member is threadedly connected to the threaded head. By tightening the locking member onto the threaded head and simultaneously cooperating with the limiting ring, the combustion hood is installed onto the gas supply pipe.

[0013] In one embodiment of this invention, multiple pairs of limiting blocks are fixed on the outer wall of the first air outlet, and multiple pairs of limiting grooves adapted to the limiting blocks are chiseled on the combustion hood. By having the multiple pairs of limiting blocks respectively locked in the multiple pairs of limiting grooves, rotation is prevented when the combustion hood is installed on the gas supply pipe.

[0014] In one embodiment of this utility model, a groove is formed on the connector, and the second slide rod slides within the groove. The groove allows the second slide rod to slide within it, thereby achieving a sliding connection between the second slide rod and the connector.

[0015] In one embodiment of this utility model, a pair of limiting sliders are fixed on the inner wall of the slide groove, and a pair of limiting slide grooves adapted to the limiting sliders are chiseled on the outer wall of the end of the second slide rod near the connector. By having the pair of limiting sliders slide in a pair of threaded heads respectively, on the one hand, rotation is prevented during the sliding of the second slide rod, and on the other hand, when the limiting slider slides to the end of the limiting slide groove near the fixed head, the pair of ignition electrodes are just at the closest ignition position.

[0016] In one embodiment of this utility model, the first spring is sleeved on the first slide rod, and the second spring is sleeved on the second slide rod to prevent the first spring and the second spring from derailing after being compressed.

[0017] In one embodiment of this utility model, the pushing mechanism includes: a moving groove, a control plate, an L-shaped push plate, and a latching assembly. The moving groove is carved into the side wall of the housing. The control plate slides within the ignition electrode. The L-shaped push plate is fixed to one end of the control plate located inside the housing, and one end of the push plate is located on one side of a pair of fixing heads. The latching assembly is installed between the L-shaped push plate and the housing to lock the L-shaped push plate in place.

[0018] When ignition is required, the control board is pushed along the trajectory of the moving groove towards the combustion hood. The control board drives the L-shaped push plate to move. The L-shaped push plate pushes a pair of fixed heads, thereby pushing the first slide rod and the second slide rod towards the combustion hood, pushing a pair of ignition electrodes to one side of the combustion hood, and locking the L-shaped push plate with the snap-fit ​​assembly. Then, ignition can be performed through the pair of ignition electrodes.

[0019] In one embodiment of this utility model, the latching assembly includes: a pair of elastic sheets, a pair of latch heads, a pair of latch slots, and a reset module. The pair of elastic sheets are respectively fixed to the two side walls of the L-shaped push plate near the control plate. The pair of latch heads are respectively fixed to the outer ends of the pair of elastic sheets. The pair of latch slots are respectively carved into the outer shell and located at the end of the outer shell near the combustion hood. The reset module is installed on the outer wall of the outer shell and is used to push the latch heads out of the latch slots. When the L-shaped push plate moves the pair of latch heads to the latch slots, the elastic force of the pair of elastic sheets springs the latch heads into the latch slots, thereby locking the L-shaped push plate in place. When the L-shaped push plate needs to move back, the reset module pushes the latch heads out of the latch slots.

[0020] In one embodiment of this utility model, the reset module includes: an elastic pressure plate and a pair of pressure heads. The elastic pressure plate is fixed to the outer wall of the housing. The pair of pressure heads are fixed to one end of the elastic pressure plate near the slot, and the pair of pressure heads are respectively located on one side of the pair of slots. In use, the elastic pressure plate is pressed towards the housing, and the elastic pressure plate drives the pair of pressure heads to move into the pair of slots. When the pair of pressure heads move into the slots, they push the pair of locking heads out of the slots.

[0021] Compared with the prior art, the ignition burner of the high-temperature and high-pressure gasification furnace of this utility model, through relevant structural design, can retract the ignition electrode after ignition, reducing the situation where the ignition electrode is in the flame or at a high temperature for a long time, thereby effectively improving the service life of the ignition electrode.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] like Figures 1 to 5 As shown, an ignition burner for a high-temperature and high-pressure gasification furnace in one embodiment of the present invention includes: a support 1, a combustion hood 103, and an ignition device 2.

[0032] like Figures 1 to 5 As shown, a gas supply pipe 101 is installed on the support 1, and multiple first gas outlet holes 102 are equally spaced at the front end of the support 1. A combustion hood 103 is installed at one end of the gas supply pipe 101 near the first gas outlet holes 102, and multiple second gas outlet holes 104 are equally spaced on the combustion hood 103.

[0033] like Figures 1 to 5 As shown, the ignition device 2 is mounted on the support 1. The ignition device 2 includes: a housing 201, a first slide rod 202, a second slide rod 203, and a pushing mechanism. The housing 201 is fixed to the side wall of the support 1 away from the combustion hood 103. Both the first slide rod 202 and the second slide rod 203 slide on the support 1, and their ends near the housing 201 are both located inside the housing 201, while their other ends are fixed with an ignition electrode 204. A fixing head 211 is fixed to the end of the first slide rod 202 and the second slide rod 203 located inside the housing 201. A connecting member 205 is fixed to the first slide rod 202 inside the housing 201, and the second slide rod 203 slides on the connecting member 205. A first spring 209 is installed between the connecting member 205 and the support 1, and a second spring 210 is installed between the fixing head 211 at the tail end of the second slide rod 203 and the connecting member 205. The pushing mechanism is mounted and slidably mounted on the housing 201, and is used to push the first slide bar 202 and the second slide bar 203 toward the combustion hood 103.

[0034] In use, the end of the gas supply pipe 101 is connected to a gas delivery pipeline. The gas flows out through the first outlet 102 at the top of the gas supply pipe 101, and then flows out through the second outlet 104 on the combustion hood 103. During ignition, the first slide rod 202 and the second slide rod 203 are pushed towards the combustion hood 103 by a pushing mechanism. When the pushing mechanism moves, it first contacts the fixed head 211 at the end of the second slide rod 203, pushing the second slide rod 203 to move. When the second slide rod 203 moves, the first slide rod 202 is moved simultaneously by the force of the second spring 210 and the connecting piece 205. At this time, the first spring 209 and the second spring 210 are compressed at the same time.

[0035] Furthermore, as the second slide bar 203 moves, it moves the ignition electrode 204 on it closer to the ignition electrode 204 on the first slide bar 202. When the ends of both the first slide bar 202 and the second slide bar 203 have moved to one side of the combustion hood 103, the pair of ignition electrodes 204 approach each other to an ignitionable position, and then ignition is achieved through an electric spark between the pair of ignition electrodes 204. After ignition, the first spring 209 and the second spring 210 push the first slide bar 202 and the second slide bar 203 back. The elastic force of the first spring 209 moves the first slide bar 202 while simultaneously moving the pair of ignition electrodes 204 away from each other.

[0036] like Figures 1 to 5 As shown, a limiting ring 105 is fixed to the end of the gas supply pipe 101 near the support 1 of the combustion hood 103. The limiting ring 105 is used to limit the installation position of the combustion hood 103. A threaded head 108 is fixed to the end of the gas supply pipe 101 near the combustion hood 103, and a locking member 109 is threaded onto the threaded head 108. By tightening the locking member 109 onto the threaded head 108, and in conjunction with the limiting ring 105, the combustion hood 103 is installed onto the gas supply pipe 101.

[0037] like Figures 1 to 5 As shown, multiple pairs of limiting blocks 106 are fixed on the outer wall of the first air outlet 102, and multiple pairs of limiting grooves 107 adapted to the limiting blocks 106 are carved on the combustion hood 103. By having the multiple pairs of limiting blocks 106 respectively engaged in the multiple pairs of limiting grooves 107, rotation of the combustion hood 103 is prevented when it is installed on the gas supply pipe 101. A sliding groove 206 is carved on the connecting member 205, and the second sliding rod 203 slides within the sliding groove 206. The sliding groove 206 allows the second sliding rod 203 to slide within it, thereby achieving a sliding connection between the second sliding rod 203 and the connecting member 205.

[0038] like Figures 1 to 5 As shown, a pair of limiting sliders 207 are fixed on the inner wall of the slide groove 206. A pair of limiting grooves 208, matching the limiting sliders 207, are carved on the outer wall of the second slide rod 203 near the connector 205. The pair of limiting sliders 207 slide within a pair of threaded heads 108, preventing rotation of the second slide rod 203 during sliding. Furthermore, when the limiting sliders 207 slide to the end of the limiting groove 208 near the fixed head 211, the pair of ignition electrodes 204 are positioned at the closest possible ignition point. A first spring 209 is sleeved on the first slide rod 202, and a second spring 210 is sleeved on the second slide rod 203, preventing the first spring 209 and the second spring 210 from derailing after compression.

[0039] like Figures 1 to 5As shown, the pushing mechanism includes: a moving groove 214, a control plate 213, an L-shaped push plate 212, and a latching assembly. The moving groove 214 is carved into the side wall of the housing 201. The control plate 213 slides within the ignition electrode 204. The L-shaped push plate 212 is fixed to one end of the control plate 213 located within the housing 201, and one end of the push plate 212 is located on one side of a pair of fixing heads 211. The latching assembly is installed between the L-shaped push plate 212 and the housing 201 to lock the L-shaped push plate 212 in place.

[0040] When ignition is required, the control plate 213 is pushed along the trajectory of the moving groove 214 toward the combustion hood 103. The control plate 213 drives the L-shaped push plate 212 to move. The L-shaped push plate 212 pushes a pair of fixed heads 211, thereby pushing the first slide rod 202 and the second slide rod 203 toward the combustion hood 103, pushing a pair of ignition electrodes 204 to one side of the combustion hood 103, and locking the L-shaped push plate 212 with the snap-fit ​​assembly. Then, ignition is performed through the pair of ignition electrodes 204.

[0041] like Figures 1 to 5 As shown, the latching assembly includes: a pair of elastic sheets 215, a pair of latch heads 216, a pair of latch slots 217, and a reset module. The pair of elastic sheets 215 are respectively fixed to the two side walls of the L-shaped push plate 212 near the control plate 213. The pair of latch heads 216 are respectively fixed to the outer ends of the pair of elastic sheets 215. The pair of latch slots 217 are respectively carved into the housing 201 and located at the end of the housing 201 near the combustion hood 103. The reset module is installed on the outer wall of the housing 201 and is used to push the latch heads 216 out of the latch slots 217. When the L-shaped push plate 212 moves a pair of locking heads 216 to the slot 217, the elastic force of a pair of elastic sheets 215 pushes the locking heads 216 into the slot 217, thereby locking the L-shaped push plate 212 in place. When the L-shaped push plate 212 needs to be moved back, the locking heads 216 can be pushed out of the slot 217 by the reset module.

[0042] like Figures 1 to 5 As shown, the reset module includes an elastic pressure plate 218 and a pair of pressure heads 219. The elastic pressure plate 218 is fixed to the outer wall of the housing 201. The pair of pressure heads 219 are fixed to one end of the elastic pressure plate 218 near the slot 217, and are respectively located on one side of the slot 217. In use, the elastic pressure plate 218 is pressed towards the housing 201, and the elastic pressure plate 218 drives the pair of pressure heads 219 to move into the slot 217. When the pair of pressure heads 219 move into the slot 217, they push the pair of locking heads 216 out of the slot 217.

[0043] Working principle: During use, the tail end of the gas supply pipe 101 is connected to the gas delivery pipeline. The gas flows out through the first gas outlet 102 at the top of the gas supply pipe 101, and then flows out through the second gas outlet 104 on the combustion hood 103. During ignition, the control plate 213 is pushed towards the combustion hood 103 along the trajectory of the moving groove 214. The control plate 213 drives the L-shaped push plate 212 to move. The L-shaped push plate 212 pushes a pair of fixed heads 211, thereby pushing the first slide rod 202 and the second slide rod 203 towards the combustion hood 103. When the L-shaped push plate 212 moves, it first contacts the fixed head 211 at the tail end of the second slide rod 203, pushing the second slide rod 203 to move. When the second slide rod 203 moves, the force of the second spring 210 and the connecting piece 205 simultaneously drives the first slide rod 202 to move. At this time, the first spring 209 and the second spring 210 are compressed at the same time.

[0044] Additionally, as the second slide bar 203 moves, it drives the ignition electrode 204 on it to move closer to the ignition electrode 204 on the first slide bar 202. When the ends of the first slide bar 202 and the second slide bar 203 have both moved to one side of the combustion hood 103, the pair of ignition electrodes 204 move closer to each other to the ignition position. Then, they are locked in the slot 217 by the locking head 216, thereby locking the L-shaped push plate 212. Then, ignition can be achieved by the electric spark between the pair of ignition electrodes 204. After ignition, the elastic pressure plate 218 is pressed towards the outer casing 201. The elastic pressure plate 218 drives a pair of pressure heads 219 to move into a pair of slots 217. When the pair of pressure heads 219 move into the slots 217, they push a pair of slot heads 216 out of the slots 217. Then, through the action of the first spring 209 and the second spring 210, the first slide rod 202 and the second slide rod 203 are pushed back. The elastic force of the first spring 209 drives the first slide rod 202 to move while moving the pair of ignition electrodes 204 away.
