Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat or radiation shielding structure provided on the outer surface of a high temperature container or the like.

A heat insulating member is installed on the outer surface of a high-temperature container or the like in order to maintain its internal temperature or to prevent the temperature of the external atmosphere from rising. These are also called heat-retaining equipment or shielding equipment depending on their main purpose, but they have in common that they function to block heat conduction.

If there is a radiation source inside the high-temperature container or the like, a shielding member for blocking radiation for another purpose is installed on the outer surface of the container.

If the high temperature container etc. is large and complex in shape and structure, it should not be manufactured as a single piece due to the difficulty of manufacturing and lathing, but instead a heat insulating part or shielding member in the shape of a substantially rectangular plate such as brick or tatami mats should be used. (hereinafter collectively referred to as shielding members) were arranged side by side and fixed with bolts. Further, the adjacent shielding members had a stepped structure so as to overlap each other.

However, a temperature difference occurs between the high temperature container and the shielding member, and a difference in heat elongation occurs between the two. The surface temperature of a high-temperature container varies or changes in various ways, and as a result, the size and direction of the difference in heat elongation are not constant. Heat dissipated and radiation leaked through the gaps, making it impossible to obtain sufficient shielding performance.

The present invention has been made in view of the above-mentioned circumstances, and provides a shielding structure that can completely shield heat or radiation without depending on the directionality of the difference in heat elongation, and is simple in structure, shape, and construction. With the goal.

The present invention will be explained below based on the illustrated embodiments, but is not limited to these embodiments.

In FIG. 1, substantially square heat insulating plates 1 are arranged side by side in the vertical and horizontal directions, forming a wedge-shaped groove 3 between them. As shown in the perspective view of FIG. 2, the heat insulating board 1 has steps 11 and 12 formed along each edge, and these steps 11 and 12 form grooves when arranged as shown in FIG. 3 to form a stepped groove 5 extending in the vertical and horizontal directions.

As shown in FIG. 5, the heat insulating board 1 is formed of an outer metal plate skin 14 and a heat insulating material 16 filled therein.

The above-mentioned stepped groove 5 is provided with an assembly type presser member 7.
is installed.

The holding member 7 is composed of a plurality of direct members 71 and a cross-shaped cross member 75, and the direct member 71 has a fitting protrusion 72 extending in the longitudinal direction and a mounting bolt through hole 73, as shown in the perspective view of FIG. It consists of a box-shaped metal jacket and a heat insulating material filled inside.

The cross member 75 has an arm 76 extending in a cross shape as shown in the perspective view of FIG.
a recess 77 that slidably receives the fitting protrusion 72 of the
and through holes 78 for mounting bolts are formed in the arms 76, respectively.

As shown in FIG. 5, the cross member 75 is composed of a metal plate outer cover 79 and a heat insulating material filled therein.

A mounting bolt 9 erected on the surface of the container 8 and arranged along the groove 3 is inserted into the through hole 7 of the linear member 71.
A shielding nut 4 to which a heat insulating gap is attached is screwed onto the tip of the mounting bolt 9 through the through hole 78 of the cross member 71 and the cross member 75, and directly presses and fixes the member 71 and the cross member 75 against the heat insulating plate 1. ing. Appropriate loosening prevention means, such as spring washers, are interposed between the shielding nut 4, the direct member 71, and the cross member 75.

In this embodiment having the above-described configuration, when the temperature of the container 8 rises, the distance between the mounting bolts 9 increases in accordance with the temperature distribution. Pressing member 7
The linear member 71 and the cross member 75 are restrained by the mounting bolts 9 passing through them and move together with them. Since the temperature of the container 8 and the temperature of the presser member 7 are different, a difference in heat elongation occurs between them, but the temperature of the presser member 7 is different.
The fitting protrusion 72 of the linear member 71 and the crossing member 75
It is absorbed by sliding with the recess 77.

Furthermore, the difference in thermal elongation between the heat insulating board 1 and the container 8 is
The surface of the container 8, including the mounting bolts 9,
It is always covered by the heat insulating plate 1, the holding member 7, and the shielding nut 4, so that it is not directly exposed to the outside air and heat radiation is blocked.

According to the present embodiment described above, the heat insulating plate 1 is not directly attached to the container 8, but is slidably fixed via the lattice-shaped holding member 7, which only needs to one-dimensionally absorb the substantial difference in heat elongation. Therefore, even if the heat elongation difference occurs in direction and varies, it is absorbed by the holding member 7, the heat insulating plate 1, and the shielding nut 4, and the container 8 is covered without any gaps, so that heat dissipation can be effectively prevented. .

Furthermore, since the holding member 7 is composed of two types of members, that is, a straight member 71 and a cross member 75, and is constructed by arranging the holding member 7 and a plurality of simple-shaped heat insulating plates 1, manufacturing, installation, and construction are easy. can be converted into

Although the above embodiments are about heat insulation or heat shielding structures, if a member with a radiation shielding function is used in place of these members, radiation emitted from the inside of a high temperature container etc. can be sufficiently shielded. Those involved will easily understand what is going on.
