Description

[Detailed explanation of the idea] The present invention relates to a mounting device for a blower in a combustor.

The combustor is equipped with a blower or other blower for supplying combustion air.

Conventionally, this blower is attached to a combustor by tightening and fixing it with bolts and nuts B through rubber bushes A, as shown in FIG.

In such a case, it is necessary to insert a rubber bushing each time and then tighten it with a bolt nut (B), which causes the inconvenience that the vibration absorption state differs depending on the tightening condition.

The purpose of the present invention is to obtain a mounting device free of such inconveniences, by bending a piano wire or other spring wire material a into a U-shape and folding it in two, and then further folding the wire material a into two. It is curved in a direction perpendicular to the curved direction and has horizontal parts 1 and 2 in two upper and lower stages, and the upper horizontal parts 1 and 1 support the blower 3, and the lower horizontal part 2
is attached to the combustor body 4, and the horizontal part 1 of the blower 3
To attach the blower 3, hold the horizontal parts 1, 1 with the claws 6, 6 cut and raised from the support plate 5 provided on the blower 3, and attach the wire rod a.
The lower horizontal portion 2 is attached to the combustor main body 4 by fitting and locking the hook pieces 12, 12 with bent tips into the through holes 8, 8 provided in the support plate 5. Notch hole 9 provided in
Then, hold down the horizontal part 2 with the lower surface of the fixture 7 with one end locked, and attach the other end of the fixture 7 with the screw 10 to the mounting board 4.
It is characterized in that it is performed by tightening and fixing it to a.

In the illustrated example, an L-shaped support plate 5 is provided on one side of the blower 3, and the cut and raised pieces 6.6 are formed on the support plate 5.

The outlet 3a side of the blower 3 is connected to the combustor main body 4 via a tube 11 made of a flexible membrane such as rubber, as has been conventionally done.

In this case, vibrations emitted from the blower 3 are absorbed by the bent portion formed between the horizontal portions 1 and 2 of the spring wire a.

Therefore, the combustor main body 4 can be prevented from vibrating due to vibrations from the blower 3.

In this way, according to the present invention, a piano wire or other spring wire material a is bent into a U-shape and folded in two, and the wire material a that has been folded in two is further bent in a direction perpendicular to the curved direction to form upper and lower parts. It is formed to have horizontal parts 1 and 2 on the steps,
Since the upper horizontal part 1 supports the blower 3 and the lower horizontal part 2 is attached to the combustor main body 4, vibrations generated by the blower 3 can be absorbed between the horizontal parts 1 and 2.
This prevents the combustor main body 4 from resonating and emitting unpleasant noises.Moreover, the blower 3 can be attached to the horizontal portion 1 using claws 6, 6 cut and raised from the support plate 5 provided on the blower 3. A hook piece 12, 1 that grips the wire material 1 and has a bent tip of the wire material a.
2 is simply fitted and locked into the through holes 8, 8 provided in the support plate 5, and the lower horizontal part 2 is attached to the combustor main body 4.
Hold down the horizontal part 2 with the lower surface of the fixing metal fitting 7, which has one end locked in the notch hole 9 provided in the mounting board 4a, and tighten the other end of the fixing metal fitting 7 onto the mounting board 4a with the screw 10. Since it is fixed, it is easy to assemble and has a simple structure, resulting in low manufacturing costs.
