Detailed Description
The present application will be described in further detail with reference to the accompanying drawings.
In the description of the present application, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application.
Example 1:
The burner, as shown in fig. 1, comprises a fire cover 200 and an ignition device 100, wherein the fire cover 200 comprises an inner fire cover 210 and an outer fire cover 220, the inner fire cover 210 is circular, the outer fire cover 220 is circular, the inner fire cover 210 is positioned in the outer fire cover 220, a plurality of fire holes 230 are formed in the inner fire cover 210 and the outer fire cover 220, and the ignition device 100 is arranged on the outer side of the outer fire cover 220 and is arranged on a liquid bearing disc 400.
The ignition device 100 comprises an ignition needle 110 and a needle protection piece 120, wherein the ignition needle 110 and the needle protection piece 120 are both arranged on a liquid bearing disc 400, the ignition needle 110 is connected with a pulser 300, the needle protection piece 120 is made of conductive high-temperature-resistant materials and is grounded, under the condition of promotion, the needle protection piece 120 is made of materials identical to those of a fire cover 200, and the grounding of the needle protection piece 120 is realized through a connecting ground wire.
The needle guard 120 is located between the burner fire cover 200 and the ignition needle 110, and the needle guard 120 may have a sheet-like or columnar structure, and in order to save costs, the sheet-like structure is exemplified in the present embodiment.
The minimum distance between the discharge head at the top of the ignition needle 110 and the fire hole 230 on the fire cover 200 is greater than the discharge distance, and the minimum distance between the discharge head at the top of the ignition needle 110 and the needle guard 120 is less than the discharge distance. The discharge distance is a distance that the ignition needle 110 can achieve discharge ignition after being electrified, and the distance is generally 4-6MM according to different voltages of the pulser 300, different fuel gases and different fuel gas output pressures.
In the case of a discharge distance of 4-6MM, the discharge distance is preferably set to be greater than 7MM, and the ignition effect of the ignition needle 110 is substantially or completely disabled at this distance, however, it is also possible to achieve ignition in a region where the discharge distance is greater than 6MM and less than or equal to 7MM, but the ignition efficiency is low, and thus the protection effect of the ignition needle 110 is weak in this region.
Referring to fig. 2, the needle guard 120 has a sheet structure, the width of the needle guard 120 is greater than the maximum distance between two fire holes 230 on the fire cover 200 on the same plane perpendicular to the ignition needle 110, the diameter of the ignition needle 110 is smaller than the width of the needle guard 120, wherein the width of the needle guard 120 is denoted by D1, the maximum distance between two fire holes 230 on the fire cover 200 on the same plane perpendicular to the ignition needle 110 is denoted by D2, and the diameter of the ignition needle 110 is denoted by D3.
Referring to fig. 3, the discharge head is lower than the lowest fire hole 230 on the fire cover 200, and the top of the needle guard 120 is higher than the lowest fire hole 230 on the fire cover 200, and it should be emphasized that the lowest fire hole 230 on the fire cover 200 refers to the lowest fire hole 230 on the fire cover 200 closest to the ignition needle 110, and in this embodiment, the top of the needle guard 120 is higher than the lowest fire hole 230 on the outer fire cover 220 because the ignition device 100 is outside the outer fire cover 220.
However, it should be noted that the distance between the discharge head and the liquid bearing disc 400 is also required to be greater than the discharge distance, and is generally required to be greater than 7MM, so that when the height of the discharge head is adjusted, if the distance is insufficient, the corresponding position of the liquid bearing disc 400 can be set in a sinking manner, for example, an integral concave ring structure is set, or a counter bore structure is set at the position of the ignition needle 110.
Example 2: as shown in fig. 4, the difference from embodiment 1 is that the position of the ignition device 100 is set between the inner fire cover 210 and the outer fire cover 220.
In this embodiment, since the fire hole 230 on the outer fire cover 220 is arranged outwards, the effect of the fire needle 110 is not easy to occur, and thus, in this embodiment, the effect of the outer fire cover 220 on the fire needle 110 is not considered, but only the effect of the inner fire cover 210 on the fire needle 110 is considered, and therefore, only the needle protection member 120 is required to be arranged between the fire needle 110 and the inner fire cover 210.
The relationship among the ignition needle 110, the needle guard 120, and the inner flame cover 210 is the same as the relationship among the ignition needle 110, the needle guard 120, and the outer flame cover 220 in embodiment 1.
In addition, if the fire hole 230 on the outer fire cover 220 is also inward in other embodiments, there may be two arrangements, one is to keep the minimum distance between the ignition needle 110 and the fire hole 230 on the outer fire cover 220 greater than the discharge distance, and the other is to form a double needle guard 120 structure by disposing the needle guard 120 between the ignition needle 110 and the outer fire cover 220. In addition, the needle guard 120 may be provided only between the ignition needle 110 and the outer flame cover 220, and the needle guard 120 may not be provided between the ignition needle 110 and the inner flame cover 210.
Example 3: as shown in fig. 5 and 6, the difference from embodiment 1 is that the needle protection member 120 includes a connecting member 121 and a deflector 122 disposed at the top of the connecting member 121 and extending in the direction of the ignition needle 110 at the end of the fire hole 230, wherein in this embodiment, the connecting member 121 and the deflector 122 are integrally bent.
It should be noted that, in the present embodiment, the width of the deflector 122 refers to the width perpendicular to the direction from the fire hole 230 to the ignition needle 110, and the width of the deflector 122 is greater than the maximum distance between two fire holes 230 on the same plane perpendicular to the ignition needle 110 on the fire cover 200, and the diameter of the ignition needle 110 is smaller than the width of the deflector 122.
In addition, the discharge head is lower than the lowest fire hole 230 of the fire cover 200, and one end of the deflector 122 facing the direction of the ignition needle 110 is higher than the ignition needle 110.
The cross section of the guide vane 122 in the width direction is linear, concave arc or convex arc, and referring to fig. 5, since the width direction of the connecting piece 121 in the embodiment is consistent with the width direction of the guide vane 122 and is integrally formed by bending, the cross section is linear.
In addition, the cross section of the flow deflector 122 perpendicular to the width direction may be in a linear or arc shape, and when the cross section is in a linear shape, the flow deflector 122 may be in a horizontal, oblique upward or oblique downward arrangement; when the cross section is arc-shaped, the flow deflector 122 may be disposed obliquely upward or obliquely downward.
By the above-described different structural arrangement, the upper surface or the lower surface of the deflector 122 is made to be a deflector surface for guiding the fuel gas injected from the fire hole 230 to the end of the ignition needle 110.
When the upper surface of the deflector 122 is a deflector surface, the end of the deflector 122 close to the fire cover 200 is lower than the lowest fire hole 230 of the fire cover 220.
When the lower surface of the deflector 122 is a deflector surface, the end of the deflector 122 close to the fire cover 200 is higher than the lowest fire hole 230 on the fire cover 200.
In the present embodiment, the guide vane 122 is an arc-shaped sheet structure with an inclined upward direction, and the upper surface is used as the guide surface, but it should be emphasized that the guide vane 122 disposed in an arc shape is not necessarily configured to be similar to the structure with one end higher and one end lower in the drawing, and only needs to ensure that the two ends and the highest point of the guide vane 122 meet the requirements under different conditions, that is, the highest point on the guide vane 122 can be at the middle position or any other position.
Example 4: as shown in fig. 7, the difference from embodiment 3 is that the deflector 122 is disposed obliquely downward in this embodiment, and the same integral bending arrangement as in embodiment 3 is still adopted in this embodiment, and the upper surface is still used as the deflector surface at this time.
Example 5: as shown in fig. 8 and 9, the difference from embodiment 3 is that the width direction of the connecting member 121 is perpendicular to the flow guiding sheet 122 in this embodiment, and the cross section of the flow guiding sheet 122 perpendicular to the extending direction is in a concave arc shape.
In addition, the connecting piece 121 and the guide vane 122 may not adopt an integral bending structure, and the connecting piece 121 is preferably arranged at a middle position below the guide vane 122, and the width of the connecting piece 121 is arranged in the same direction as the guide vane 122, so that the connecting piece 121 can also play a role in blocking.
In this embodiment, the upper surface is still used as the guide surface.
Example 6: as shown in fig. 10, the difference from embodiment 5 is that the lower surface is used as the guide surface in this embodiment, wherein the guide vane 122 is in the shape of an upwardly convex arc, and the end of the guide vane 122 connected to the needle guard 120 is higher than the lowest fire hole 230 of the fire cover 200, and at this time, unlike embodiments 3,4, and 5 described above, the fuel gas flows along the lower portion of the guide vane 122.
Example 7: as shown in fig. 11, the difference from embodiment 1 is that the needle protection member 120 has a cylindrical structure, which may be a cylindrical structure, an elliptic cylinder, a polygonal column, or the like, wherein when the polygonal column is adopted, the side surface of the polygonal column may be inclined to face the fire hole 230, so that the gas sprayed from the fire hole 230 may diffuse to both sides under the guidance of the side surface, and further the needle protection member 110 is protected, and in this embodiment, the cylindrical structure is exemplified.
Referring to fig. 12, the needle guard 120 is provided with a pilot hole 123 penetrating from the outer flame cover 220 side to the ignition needle 110 side, one end of the pilot hole 123 near the flame cover 200 is higher than the other end, and the height of the high end is higher than or equal to the position of the lowest flame hole 230 on the flame cover 200.
