As shown in fig. 7, the lower burner supporting device 3 of the present invention includes a lower plate 31 and an upper plate 32, wherein a plurality of adjusting sleeves 310 are disposed on the lower plate 31, a plurality of adjusting columns 320 are disposed under the upper plate 32, and the adjusting columns 320 are correspondingly installed in the adjusting sleeves 310. In the preferred embodiment, the upper plate 32 and the lower plate 31 are both circular plates, four sleeve adjusting sleeves 310 are disposed on the lower plate 31, correspondingly, four adjusting posts 320 are disposed under the upper plate 32, and then the four adjusting posts 320 are inserted into the four adjusting sleeves 310. Of course, the upper plate 32 and the lower plate 31 may also be rectangular or other shapes, the number of the adjusting columns 320 and the adjusting sleeves 310 may also be three or more, and in the specific implementation process, the adjusting sleeves 310 are provided with locking bolts 311 for locking the adjusting columns 320. When the upper plate 32 is leveled, the lock bolt 311 is tightened to prevent the upper plate 32 from being deviated on the surface, thereby keeping the lower opposing burner 4 horizontal and thus the nozzle of the lower opposing burner 4 horizontal.
The structure of the upper counter-flow burner 6 and the lower counter-flow burner 4 can adopt the structure of the existing burner, the flame is sprayed out from the nozzle of the burner, and the flame sprayed out from the nozzles of the upper counter-flow burner 6 and the lower counter-flow burner 4 forms counter-flow flame.
The flame test stand of the present invention can be used in the following manner, and a preferred embodiment thereof will be described with reference to fig. 1. The leveling platform 2 is first adjusted to adjust both adjusters 2 to the initial position to zero, i.e. the adjusters are zeroed as described above, i.e. the pointer 2112 on the first adjusting plate 210 is aligned with the zero scale of the second scale 215. Next, the locking nut 515 of the upper burner adjusting means 5 is loosened so that the movable member 52 can be adjusted up and down, and then the first adjusting member 511 is rotated to adjust the downward movement of the movable member 52 until the movable member is zeroed, at which time the upper surface of the fixed block 512 is exactly aligned with the zero scale of the first scale 521. The lower burner support 3 is then adjusted to adjust the distance of the upper plate 32 relative to the lower plate 31 until the nozzles of the lower opposed burners 4 contact the nozzles of the upper opposed burners 6, then the upper plate 32 is leveled and the locking bolts 311 are tightened, then the leveling platform 2 is fine-tuned to align the nozzles of the lower opposed burners 4 with the nozzles of the upper opposed burners 6. Finally, the movable member 52 is adjusted to move upward by the first adjusting member 511, the lower opposite burner 4 is driven to move upward, and the predetermined scale is adjusted with reference to the first scale 521, and then stopped, and the lock nut 515 is locked. After the adjustment of the steps, the distance between the nozzle of the upper opposite-direction burner 6 and the nozzle of the lower opposite-direction burner 4 is not increased, and the nozzle of the upper opposite-direction burner 6 and the nozzle of the lower opposite-direction burner 4 are aligned.
The above examples are only preferred embodiments of the present invention, it should be noted that: it will be apparent to those skilled in the art that various modifications and equivalents can be made without departing from the spirit of the invention, and it is intended that all such modifications and equivalents fall within the scope of the invention as defined in the claims.
