Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a convection type open combustor.

Structure of conventional example and its problems As shown in Fig. 1, this type of conventional combustor is provided with a guard 2 on the outer periphery of the outer cylinder 1 of the combustor, but no guard is provided on the top plate 3. There was a risk of getting burned if you touched this top plate 3 with your hands. Therefore, we considered installing a guard on the top plate 3 as well, but since this guard covers the top plate, which is the highest temperature in the combustor, it must be installed at a considerable distance from the top plate 3. First, the combustor as a whole becomes extremely large. As a result, the amount of packaging required increased, leading to problems such as increased transportation costs.

Purpose of the invention This invention was created in view of the above points.
The purpose is to eliminate the risk of burns on the top plate and at the same time reduce the packaging time.

Structure of the invention In order to achieve the above object, the invention makes the guard covering the outer cylinder and the upper part of the top plate movable downward,
The packaging time can be reduced by moving the guard downward during packaging.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to FIGS. 2 to 5. Reference numeral 4 denotes a combustor main body, which is composed of a tank section 4a and a combustion section (not shown) installed above the tank section 4a. . Reference numeral 5 designates an outer cylinder provided to surround the combustion section, and reference numeral 6 designates a top plate that covers the upper opening of the outer cylinder 5. Reference numeral 7 denotes a guard that covers the outer periphery of the outer cylinder 5 and the upper part of the top plate 6. This guard 7 has horizontal ring rods 8 and 9.
a, 9b, 9c are connected by several vertical bars 10, and the upper end of the vertical bar 10 is bent horizontally toward the center, and a ring bar 11 is attached to this horizontal vertical bar 10a.
is fixed to form a substantially cylindrical shape with a bottom. The distance 12 between the upper end of the guard 7 and the top plate 6 is a sufficient distance and is smaller than the distance 13 between the lower end of the guard 7 and the lower end of the outer cylinder 5. Further, both ends of the horizontal ring rod 9a are bent horizontally toward the outer cylinder 5 as shown in FIG. 5, and the ends are bent upward and inserted into the guard fitting 14. Also, bend the lower ends of several of the vertical bars 10 toward the outer cylinder, and after bending the ends downward, open the holes 1 in the outer cylinder 6.
It is inserted in 7. 15 is a guard stopper 15
It is fastened to the outer cylinder 6 with screws 16.

In the above configuration, when in use, the guard 7 is positioned at a certain distance from the top plate 6, as shown by the solid line in FIGS. 2 and 5, to prevent hands etc. from touching the top plate 6. At the same time, even if your hands or the like touch the guard 7, you will not get burned.

Next, when packaging, first loosen the screw 16, remove the guard stopper 15, and move the guard 7 downward. Then, insert the part that was inserted into the guard stopper 14 into the preliminary guard stopper 14a as shown by the imaginary line in FIG. Guard stopper 1
5 to the outer cylinder 6 with screws 16. This results in the fourth
As shown in the figure, the guard 7 moves downward, making the entire combustor more compact. In other words, the amount of packaging required is reduced.

6 and 7 show another embodiment, in which the guard is separated into an outer cylinder guard 19 and a top plate guard 22. The outer cylinder guard 19 is
It is constructed by connecting horizontal ring-shaped rods 20, 21a, 21b, and 21c with several vertical rods 22. Further, the top plate guard 22 is formed into a disk shape by fixing horizontal ring rods 22a and 22b to several horizontal rods 23 facing toward the center. Several of the horizontal rods 23 are bent downward from inside the inner diameter of the outer cylinder 5 to form mounting legs 23. This mounting leg 23 has a retaining portion 23a bent at its lower end, and
A stopper part 23b is formed above the stopper part 23b, and is fitted into a mounting hole 24 provided in the top plate 6 as shown by the solid line in FIG. Note that the mounting hole 24 is formed in a substantially L-shape so that the guard attachment/detachment hole 24a and the engagement hole 2
4b, and a detachment prevention part 24c is formed between them.

In this embodiment, at the time of packaging, the mounting legs 23 of the top plate guard 22 are first elastically deformed to pass through the detachment prevention part 24c of the mounting hole 24 and moved to the guard attachment/detachment hole 24a. As a result, the stopper portion 23b of the mounting leg 23 is released, and the mounting leg 23 is positioned below the top plate, that is, on the outer cylinder 5, as shown by the imaginary line in FIG.
The entire top plate guard 22 is lowered, and the entire combustor is made compact.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, it is possible to prevent burns caused by touching the top plate as well as burns caused by touching the guard on the top plate. The provision of the upper guard has great effects, such as solving the large-scale problem of packaging time and eliminating a large increase in transportation costs.
