In normal installation, each pair of through holes is arranged on the bracket in an upper-lower mode. The through hole has the positioning function, and the aperture of the through hole is smaller than the shaft shoulder size of the ignition needle or the flame probe, so that the two needles cannot fall down under the action of gravity when being vertically placed.
6) And the spigot nuts are arranged to limit the maximum lifting height of the gas path pipe. That is, when the ignition needle or the flame probe needs to be disassembled, the maximum drawing range of the gas path pipe needs to be limited. The spigot nut is in threaded fit with the horizontal pipe section, so that the maximum lifting height can be adjusted, and the use flexibility of the invention is ensured.
7) The arrangement of the chamfer angle plays a role of avoiding the installation position of the flame probe on one hand, so that the flame probe and the gas path pipe are mutually avoided; on the other hand, the flame probe can be directly positioned on the gas spraying path of the horizontal pipe section, so that the flame probe can be used for detecting the flame of the long-term open flame and the flame of the main furnace end at the same time, and multiple purposes are achieved.

Detailed Description
The reliability of the electronic ignition depends on multiple factors, in addition to the performance factors of the ignition needle itself, on the gap between the ignition needle and "ground", the intensity of the arc, the location of the passage through which the premixed combustion gas flows, etc. Generally, the small ignition gap can lead to low discharge voltage, short arc pulling length, low arc intensity and high ignition difficulty; the concentrated location of the arc, if offset from the primary path through which the gas flows, can lead to difficulties in igniting the gas. The stability of the pilot flame combustion also depends on multiple factors, and is influenced by the magnitude of the pilot flame gas input power and the variation factor of the air-fuel ratio caused by different air distribution, and also depends on the flame separation degree of the pilot flame, the air pressure level in the hearth and the like. If the flame is severely lifted or the furnace pressure is too large or suddenly too small, the open flame is easy to extinguish. Of course, if the contact condition of the flame probe and the flame is not good, the igniter can start the flameout protection function, and the flameout of the open flame can be caused.
In view of the above, the invention provides a series of improved structures, and aims to ensure that the open flame of the stove keeps a normal and stable combustion state even under the airtight combustion working condition of the hearth and under the condition of high pressure of the hearth or frequent sudden lifting of the pressure of the hearth, and finally provide preconditions for ensuring the waste heat utilization efficiency and the idle combustion prevention function of the stove.
For ease of understanding, the specific structure and operation of the present invention will be further described herein with reference to FIGS. 1-6:
The specific structure of the invention is shown in fig. 1-4, and the main structure of the invention comprises an L-shaped tubular gas pipe 10, a straight rod-shaped ignition needle 20, a bent tubular flame probe 60, a bracket 40 and a positioning plate 50 which plays a role in positioning a spigot. Wherein:
The air passage pipe 10 is rectangular tubular as shown in fig. 1 and 3, and is composed of a vertical pipe section 12 and a horizontal pipe section 11. The horizontal tube section 11 serves as a nozzle section for the cooperation of the ignition needle 20 for the arrangement of the honeycomb panel 30. The honeycomb plate 30 is shown in fig. 2, which is a circular plate with a plurality of through holes arrayed or distributed around the plate. In actual operation, the ignition needle 20 extends into the horizontal pipe section 11 through the pressure relief breathing hole 13, so that an arc discharge gap can be formed by utilizing the gap between the ignition needle 20 and the pipe wall of the horizontal pipe section 11; on the other hand, the pressure relief breathing holes 13 and the auxiliary holes 14 shown in fig. 4-6 can be utilized to cooperatively realize the purposes of pressure relief of the pressure in the hearth and combustion maintenance of the fire scene environment in the gas path pipe 10. Of course, in actual operation, instead of simply dividing the air pipe 10 into the vertical pipe section 12 and the horizontal pipe section 11, as shown in fig. 3, the positioning plate 50 may be fixedly connected with an "L" shaped outer pipe body, and an inner pipe body is sleeved in the outer pipe body to form the vertical pipe section 12, which is, of course, a further optimized design of the air pipe 10, and may be modified as appropriate according to actual situations, and will not be described here again.
Further, the flame probe 60 itself presents a three-section curved shape as shown in fig. 3-6, including a horizontal pipe body, a 45 ° connecting pipe body and a vertical pipe body, and by means of the matching of the chamfer 11a at the horizontal pipe section 11, the flame probe 60 and the horizontal pipe section 11 can be ensured to be coaxial with each other, so that the purpose of simultaneously detecting the pilot flame and the main burner flame can be achieved by means of one flame probe 60.
On the one hand, the bracket 40 realizes the integral fixation of the ignition needle 20, the gas pipe 10 and the flame probe 60 by the through holes; on the other hand, the positioning plate 50 is used to match the ignition needle 20 and the flame probe 60, so as to ensure the accurate positioning of the installation positions of the ignition needle and the flame probe. By the above-described structure of the bracket 40, easy dismounting of the whole structure is also achieved. Once a certain part is damaged, the ignition needle 20 and the flame probe 60 can be randomly and conveniently dismounted and mounted on line by only pulling the gas path pipe 10 upwards, and the dismounting and mounting process is extremely convenient.
For a further understanding of the present invention, the following description of the specific disassembly and assembly operations of the present invention will be provided with reference to fig. 1 and 4-6:
The invention is in the normal working state, which is shown in figure 1, and the parts are matched compactly. When the ignition needle 20 or the flame probe 60 and even the air pipe 10 have a problem and need to be detected or replaced online, the air pipe 10 can be pulled out as shown in fig. 4, so that the positioning plate 50 is separated from the ignition needle 20 and the flame probe 60 first. Thereafter, the vertical pipe section 12 of the air pipe 10 is rotated as shown in fig. 5, so that the positioning plate 50 completely avoids the removal path of the ignition needle 20 and the flame probe 60. Finally, as shown in fig. 6, the ignition needle 20 or flame probe 60 may be pulled out in the upward direction for replacement. When the ignition needle 20 or the flame probe 60 needs to be disassembled, the maximum drawing range of the air pipe 10 is limited, and the maximum drawing range is realized by means of limit fit between the spigot nut 70 and the corresponding side wall of the bracket 40 as shown in fig. 6. The maximum pull-out range or the maximum lifting height can be adjusted due to the threaded engagement between the spigot nut 70 and the horizontal tube segment 11, so as to ensure the flexibility of use of the invention.
