a burning torch body 2;
the ignition assembly comprises an ignition needle 1 which is arranged in an ignition gun body 2;
the gas pipeline 3 is communicated with the inside of the ignition gun body 2 and is used for conveying gas to the ignition gun body 2;
and the compressed gas pipeline 4 is communicated with the inside of the ignition gun body 2 and is used for conveying high-pressure gas to the ignition gun body 2 so as to clean the ignition needle 1.
So arranged, the gas can be delivered into the ignition gun body 2 through the gas pipeline 3 when the ignition is performed. Before ignition or at other moments when the ignition needle 1 needs to be cleaned, high-pressure gas can be conveyed into the ignition gun body 2 through the compressed gas pipeline 4, dust attached to the ignition needle 1 is blown through the high-pressure gas, so that the cleaning of the ignition needle 1 is ensured, the influence of the dust on ignition equipment is reduced, and the normal use of the ignition equipment is ensured.
In one embodiment, the gas pipe 3 is provided with a compressed gas inlet;
the compressed gas pipeline 4 is connected with the compressed gas inlet so as to be communicated with the inside of the ignition gun body 2 through the gas pipeline 3;
a first solenoid valve 41 provided on the compressed gas pipe 4;
a second solenoid valve 31 is provided on the gas conduit 3 between the compressed gas inlet and the gas inlet end of the gas conduit 3.
So arranged, the compressed gas pipe 4 can share part of the pipe with the gas pipe 3, so that the structure of the burner ignition device is simpler. Further, in the solution provided in this embodiment, the on-off state of the compressed gas pipe 4 and the gas pipe 3 may be changed by controlling the opening and closing states of the first electromagnetic valve 41 and the second electromagnetic valve 31, so that the gas may be controlled to enter the inside of the ignition gun body 2 or the high-pressure gas (compressed gas) may be controlled to enter the inside of the ignition gun body 2 through the first electromagnetic valve 41 and the second electromagnetic valve 31.
In the ignition process, not only the fuel gas but also the oxygen gas is required. Based on the above, in the scheme provided by the application, the ignition gun body 2 comprises a straight pipe, a contracted pipe and a connecting block, wherein a gas pipeline is communicated with the contracted pipe through the connecting block, and the inner diameter of the straight pipe and/or the contracted pipe is larger than the inner diameter of the gas pipeline 3; the straight pipe and/or the contracted pipe are provided with a plurality of air inlets along the circumference of the pipe wall. So set up, when gas flows into the ignition rifle body 2 inside from gas pipeline 3 with higher speed in the ignition process, because the internal diameter of straight tube and/or shrink pipe is greater than gas pipeline 3 internal diameter, according to the hydrodynamics principle, the air in the inlet port outside can be inhaled into intraductally, provides the partial oxygen that gas burning needs.
In practical applications, the burner ignition apparatus further comprises: a gas supply device 6 connected to the gas pipe 3; the gas pipeline is provided with a gas pressure sensor for monitoring the gas pressure condition of the gas in the gas pipeline. So arranged, the gas supply means 6 can feed gas into the gas duct 3. In practical application, the gas supply device 6 comprises at least one gas cylinder, and if the number of the gas cylinders is one, after the gas in the gas cylinder is used up, a prompt device can prompt a relevant person to replace the gas cylinder in time; if the gas supply device includes a plurality of gas cylinders, after the gas in one gas cylinder is used up, the gas supply device 6 can be switched to provide the gas by using other gas cylinders, and further, the prompt device can prompt the relevant personnel to timely supplement or replace the empty gas cylinder in the non-working state.
Specifically, the gas supply device 6 may include two gas bottles and a three-way electromagnetic valve; the two gas bottles are connected with a gas pipeline 3 through a three-way electromagnetic valve. So that one of the two gas cylinders can be controlled by the three-way electromagnetic valve to supply gas for the gas pipeline 3; specifically, the gas cylinder for supplying gas can be selected by a three-way electromagnetic valve.
When the gas inside the gas cylinder is exhausted, the relevant personnel are timely prompted to replace or supplement the gas cylinder.
In one embodiment, the burner ignition device is provided with a gas pressure sensor on the gas conduit for monitoring the gas pressure conditions of the gas in the gas conduit. If the gas pressure sensor is not able to detect a change in the gas pressure during the gas supply by the gas supply device 6 (the change here means a change in the "detected pressure value after gas supply" compared with the "detected pressure value when gas is not supplied") or if the detected gas pressure is smaller than the preset value, it is considered that the gas supply device 6 is not normally supplying gas at this time and that the gas bottle is not supplied with gas at this time.
In the conventional ignition gun, when the ignition is performed, the ignition needle 1 is ignited by generating electric sparks with the ignition cylinder or with metal near the ignition needle 1, the distance between the ignition needle 1 and the metal (negative electrode) generating electric sparks needs to be manually adjusted, if the relative position adjustment is not good, ignition failure is easily caused, the user has great difficulty in replacing the ignition needle 1, and the ignition is affected when the adjustment is not in place.
Based on this, the ignition needle 1 of the burner ignition apparatus provided in the embodiment of the present application includes:
a main needle 11, a sub-needle 12 and a positioning plate 13;
the locating plate 13 is arranged at one end far away from the gas pipeline 3, at least two containing holes are arranged on the locating plate 13, and the main needle and the auxiliary needle penetrate through the containing holes and extend towards the ignition end of the combustor ignition device.
The ignition end of the burner ignition device refers to an end where open flame occurs when the burner ignition device ignites. Specifically, the positioning plate 13 is used for fixing the main needle 11 and the auxiliary needle 12, so that the main needle 11 and the auxiliary needle 12 can be relatively fixed, the distance between the ignition end of the main needle 11 and the auxiliary needle 12 is not required to be manually adjusted, and the ignition effect is more stable.
Further, the positioning plate 13 may be provided with a plurality of accommodating holes, and in practical application, if the ignition effect is not good, the accommodating holes through which the main needle 11 and the sub-needle 12 pass may be replaced to adjust the relative distance between the main needle 11 and the sub-needle 12.
Specifically, the positioning plate 13 may be a ceramic positioning plate.
Further, the ignition assembly also comprises a fixed joint 15 and a high-pressure bag 8;
the fixed joint 15 is detachably connected with the ignition gun body; specifically, the fixed joint can be fixed with the ignition gun body in a detachable fixing mode such as threads, buckles and the like.
The side of the main needle 11, which is far away from the ignition end, is connected with a fixed joint 15 through an insulating layer coated on the surface of the main needle 11, and is connected with a high-voltage bag 8 through the fixed joint 15;
the side of the auxiliary needle 12 away from the ignition end is fixedly arranged on the fixed joint 15 and is electrically connected with the fixed joint 15. So as to achieve the effect of grounding.
In practical application, the ignition assembly is detachably arranged in the ignition gun body 2 as a whole, and when the ignition needle 1 needs to be replaced, only the fixing state of the fixing joint 15 and the ignition gun body 2 needs to be changed to replace the ignition assembly. For example: the fixed joint 15 can be provided with threads, the fixed joint 15 is screwed in the ignition gun body 2 through threads, when the ignition needle 1 is replaced, the ignition needle 1 is only required to be rotated, the fixed joint 15 is separated from the ignition gun body 2, the old ignition assembly can be detached, and then a new ignition assembly is screwed and fixed in the ignition gun body 2 through the fixed joint 15, so that the replacement of the ignition needle 1 is completed.
It should be noted that, in the ignition assembly, the high-voltage package 8 is detachably connected with the fixed connector 15 through the high-voltage ignition wire 7, and when the new ignition assembly is replaced, a part of the high-voltage package 8 may not be replaced, namely: the old high-pressure bag 8 of the ignition assembly is detached, and the new ignition assembly is combined by the old high-pressure bag 8 of the ignition assembly, the new ignition needle and the new fixing joint.
To sum up, the burner ignition apparatus provided by the present application includes: a main needle 11, an auxiliary needle 12, a positioning plate 13, a ceramic rod 14 and a fixed joint 15; the ignition gun comprises an ignition gun body 2, a gas pipeline 3, a gas pressure sensor 5, a first electromagnetic valve 41, a compressed gas pipeline 4, a second electromagnetic valve 31, a gas supply device 6, a high-pressure ignition wire 7, a high-pressure bag 8 and the like. The gas supply device 6 comprises at least one gas cylinder, wherein the positioning plate 13 is a ceramic plate; the ceramic rod 14 is an insulating layer wrapped on the surface of the main needle 11; the fixed joint 15 is a threaded joint. The ignition gun body 2 includes: a contracted pipe 21 and a straight pipe.
Specifically, the main pin 11 is fixed inside the ceramic rod 14 and connected to the high-voltage ignition wire 7, and the sub pin 12 is fixedly connected to a screwed joint, which is fixed outside the ceramic rod 14. When the high-voltage package 8 works, high voltage generated by the high-voltage package 8 is transmitted to the main needle 11 through the high-voltage ignition wire 7, electric sparks are generated between the main needle 11 and the auxiliary needle 12 (the distance between the main needle 12 and the auxiliary needle 12 is about 3-5mm, and the auxiliary needle 12 is connected with the ignition gun body through a threaded joint and is equivalent to grounding). Because the auxiliary needle 12 is longer, in order to avoid the auxiliary needle 12 from deforming or vibrating to influence the ignition when the ignition is performed, the main needle 11 and the auxiliary needle 12 are fixed through a ceramic plate, the ceramic plate is made of insulating ceramic, is high-temperature resistant and insulating, and can effectively control the distance between the main needle 12 and the auxiliary needle 12 and avoid the auxiliary needle 12 from deforming and vibrating. The main needle 11, the auxiliary needle 12, the ceramic plate, the ceramic rod 14 and the threaded joint form a whole, the whole is fixed on the ignition gun body through threads, when the ignition needle 1 needs to be replaced, only the whole formed by the main needle 11, the auxiliary needle 12, the ceramic plate, the ceramic rod 14 and the threaded joint needs to be replaced, and the distance does not need to be manually adjusted when the ignition needle 1 is installed and replaced. Further, a plurality of air inlets are formed in the shrinkage tube 21 and the straight tube along the circumference of the tube wall, fuel gas flows into the shrinkage tube 21 and the straight tube from the fuel gas pipeline 3 at a high speed in the ignition process, and because the inner diameters of the shrinkage tube 21 and the straight tube are larger than the inner diameter of the fuel gas pipeline 3, air outside the air inlets can be sucked into the tube according to the fluid mechanics principle, so that partial oxygen required by fuel gas combustion is provided. Further, one end of the compressed gas pipeline 4 is connected with compressed gas supply equipment, and the other end is connected with the burning torch body 2 through the gas pipeline 3, and is used for conveying high-pressure gas to the burning torch body 2 so as to clean the ignition needle 1.
When the ignition is performed by the above-mentioned burner ignition device, the first electromagnetic valve 41 is controlled to be turned on for a certain period of time and then turned off (compressed gas enters the inside of the ignition gun through the gas pipeline 3 to clean dirt on the ignition needle 1), then the high-voltage package 8 starts to work, high voltage is delivered to the main ignition needle 1 through the high-voltage ignition wire 7, electric sparks are generated between the main ignition needle 1 and the auxiliary ignition needle 1, and meanwhile, the second electromagnetic valve 31 is turned on to perform ignition, and it is noted that in specific application, the occurrence sequence of generating electric sparks and delivering fuel gas is not sequential. Namely: the spark may be generated after the fuel gas is delivered, or the spark may be continuously generated after the fuel gas is delivered. The time interval between the two steps should remain within a preset time period. Specifically, the preset duration may be, but is not limited to, 3 seconds.
In this embodiment, taking "delivering fuel gas" and then "generating electric spark" as an example, the air pressure sensor detects a pressure signal (opening fuel gas, introducing ignition fuel gas into the fuel gas pipe and the ignition gun for ignition), if the pressure is normal, continuing to open the second electromagnetic valve 31 for ignition, if a flame signal is detected after 3s, then surface ignition is successful, if no flame signal is detected, closing the second electromagnetic valve 31 and the high-pressure bag 8, automatically restarting the system, if no ignition is successful for three consecutive times, considering that ignition fails, and after each ignition failure, the system can clean the inside of the ignition gun again by adopting compressed gas, thereby improving ignition success rate. If the pressure sensor can not detect the pressure after the fuel gas is opened, the three-way valve is operated to switch to another fuel gas cylinder to work, so that the fuel gas flame is ensured to be large enough to ignite the fuel oil, and the user is reminded of replacing the fuel gas cylinder on the interface of the user.

specifically, the preset time may be 1 second. Namely: after the gas pipeline starts to convey the gas pipeline for 1 second, a detection signal of the air pressure sensor is obtained.
When the detection signal is smaller than a preset value, a prompt message is sent to remind the gas bottle to be replaced; and/or controlling the gas supply device to switch the gas bottle for supplying gas.
The gas supply device can determine whether to supply gas into the gas pipeline based on the detection signal, and if the gas supply device does not supply gas into the gas pipeline, the gas bottle which is in gas supply in the gas supply device is empty, so that other gas bottles with gas can be replaced in time to supply gas. The air-conditioned gas bottle can be replaced or supplemented by a preset prompting device for prompting related personnel. Specifically, the prompting device can be, but is not limited to, an acoustic prompting device, a display screen and a buzzer.

S304, acquiring a pressure signal detected by the air pressure sensor.
S305, judging whether fuel gas exists in the fuel gas pipeline or not based on the pressure signal;
if no gas exists in the gas pipe, step S306 is executed, and if gas exists in the gas pipe, step S307 is executed.
S306, controlling the gas supply device to switch other gas cylinders to supply gas and reminding to replace the gas cylinders.
S307, judging whether ignition is successful.
Specifically, the manner of determining whether the ignition is successful is to determine whether a flame exists, specifically, whether a flame exists may be determined based on a preset device after 3 seconds of executing steps S302 and S303, and if a flame exists, the ignition is successful. If no flame is present, the ignition fails.
If the ignition is successful, step S306 is executed, if the gas exists in the gas pipeline, otherwise step S308 is executed.
S308, controlling the second electromagnetic valve to close and the high-voltage bag to stop working, and accumulating the closing times of the second electromagnetic valve.
S309, judging whether the closing frequency of the second electromagnetic valve is less than or equal to 3.
