In the prior art, the inner ring fire cover is usually designed as a split type to control the size of the fire hole or clean the fire hole. Although the split type fire cover is easy to adjust the size of the fire hole or clean the fire hole, the flame stability is poor, and the flame is easy to separate in the cold state or high pressure state. SUMMARY
[0003] The utility model wants to overcome the prior art's inner ring fire cover's defect that the size of the fire hole is difficult to adjust and the fire hole is inconvenient to clean, and provide an inner ring fire cover and a burner.
[0004] The utility model solves the above technical problem through the following technical scheme:
[0005] The utility model provides an inner ring fire cover, the inner ring fire cover includes the fire cover body, be equipped with a plurality of fire holes on the fire cover body, the inner ring fire cover still includes the adjusting part, be equipped with the placement slot with the adjusting part shape matching on the fire cover body, the adjusting part can be inserted in the placement slot and passes through the placement slot, to the first hole section and the second hole section with the fire hole is divided, the first hole section is located at the radial inner side of the adjusting part, the second hole section is located at the radial outer side of the adjusting part, the adjusting part with the extension direction of the fire hole is not parallel,
[0006] Be equipped with a plurality of the adjusting hole that passes through the adjusting part on the adjusting part, the both ends of the adjusting hole are communicated with the first hole section and the second hole section respectively, the adjusting part can rotate along the circumference of the inner ring fire cover, to change the coincidence area of the adjusting hole and the fire hole in the radial direction of the inner ring fire cover.
[0007] In the scheme, the inner ring fire cover adjusts the size of the fire hole through the adjusting part, the placement slot is equipped on the inner ring fire cover body, the adjusting part is inserted into the placement slot, because the extension direction of the adjusting part and the fire hole is not parallel, the adjusting part can pass through the fire hole to divide the fire hole into the first hole section and the second hole section, the fire hole is equipped on the adjusting part, and the both ends of the fire hole are communicated with the first hole section and the second hole section respectively, when the user needs to adjust the fire hole, the adjusting part can be rotated along the circumference of the inner ring fire cover, thereby changing the coincidence area of the adjusting hole and the fire hole in the radial direction of the inner ring fire cover, that is, adjusting the area of the adjusting hole in the fire hole, thereby adjusting the size of the fire hole. Moreover, when the adjusting part rotates, the dirt accumulated in the fire hole can also be disassembled, so that the dirt particles become smaller, and when the adjusting part is disassembled, the dirt is more likely to flow out, and the fire hole is more convenient to clean.
[0008] Preferably, the first hole section and the second hole section are not parallel in the extending direction.
[0009] In this solution, by setting the extending direction of the first hole section and the second hole section as not parallel, the gas collides with the inner wall surface of the fire hole for multiple times when passing through the fire hole, so as to slow down the flow speed of the gas in the fire hole, and the gas forms a vortex in the fire hole, preventing backfire.
[0010] Preferably, in the direction from the radial inner side of the inner ring fire cover to the radial outer side, the first hole section extends obliquely downward, and the second hole section extends obliquely upward.

[0014] Preferably, the adjusting hole and the fire hole correspond to each other in the circumferential direction of the adjusting member.
[0015] In this solution, by setting the adjusting hole and the fire hole to correspond to each other in the circumferential direction of the adjusting member, the size of the fire hole can be adjusted for multiple fire holes distributed in the circumferential direction of the inner ring fire cover. When the adjusting member rotates, the relative position of the multiple fire holes and the adjusting hole can be adjusted, so that the adjustment of the size of the fire hole is more convenient.
[0016] Preferably, the adjusting member is arranged around the inner ring fire cover in the circumferential direction.
[0017] In this solution, by arranging the adjusting member around the inner ring fire cover in the circumferential direction, the adjusting member is more convenient to rotate in the circumferential direction of the inner ring fire cover, and it is more convenient to adjust the size of the multiple fire holes distributed in the circumferential direction of the inner ring fire cover, and the user operation is more convenient.
[0018] Preferably, the adjusting member and the placing groove extend in the vertical direction.
[0019] In the scheme, by setting the adjusting member and the placing groove to extend along the vertical direction, it is more convenient for the user to put the adjusting member into the placing groove, and when the adjusting member is disassembled, the dirt in the fire hole can flow out along the vertical direction, and the vertically extending adjusting member and placing groove are also more convenient for production and manufacturing.
[0020] Preferably, the opening of the placing groove is arranged at the lower end of the fire cover body, and the adjusting member is inserted into the placing groove from the lower end of the fire cover body.
[0021] In the scheme, by arranging the opening of the placing groove at the lower end of the fire cover body, and inserting the adjusting member into the placing groove from the lower end of the fire cover body, the opening of the placing groove can be hidden, avoiding the opening of the placing groove exposed outside the inner ring fire cover, and also facilitating the dirt in the fire hole to flow out from the lower side of the inner ring fire cover during cleaning, and facilitating the installation and disassembly of the adjusting member.
[0022] Preferably, the adjusting member is further provided with a positioning member extending from the lower end of the adjusting member to the radial inner side of the adjusting member.
[0023] In the scheme, by arranging the positioning member on the adjusting member, the user can rotate the positioning member to drive the adjusting member to rotate, which is more convenient for the user to operate, and by observing the position of the positioning member, the rotation angle of the adjusting member can be determined more conveniently, and by extending the positioning member from the lower end of the adjusting member to the radial inner side of the adjusting member, it is more convenient for the user to rotate the positioning member along the circumference of the inner ring fire cover.
[0024] The utility model also provides a kind of combustor, and the combustor includes above-mentioned inner ring fire cover.
[0025] The utility model has the following positive progress effect:
[0026] The inner ring fire cover adjusts the size of the fire hole by setting the adjusting member, the inner ring fire cover body is provided with a placing groove, and the adjusting member is inserted into the placing groove. Since the extending direction of the adjusting member and the fire hole is not parallel, the adjusting member can penetrate the fire hole to divide the fire hole into a first hole section and a second hole section. The adjusting member is provided with a fire hole, and the two ends of the fire hole are communicated with the first hole section and the second hole section respectively.
