Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a space adjusting spacer and a space adjusting spacer group using the same.
More specifically, the present invention relates to a spacer that can adjust the mounting interval and the mounting position of all members in various industrial fields, and in particular, a spacer for spacer adjustment that is suitable for adjusting the height of a coil incorporated in a fluidized bed reactor. And a spacer group for spacing adjustment using the same.

2. Description of the Related Art FIG. 3 shows a fluidized bed type reaction device,
Is a cooling or heating coil. The coil C is hung from a support beam B horizontally laid in the tank via a mounting member 10. However, in this support structure, a height difference occurs in the level surface of the lower surface of the coil C between the coil C close to the wall surface of the container and the coil C far from the wall surface, that is, the coil C at the center of the container due to the deflection of the support beam B and the like. Therefore, in order to adjust the level surface of the coil lower surface, which is an important factor for obtaining uniform heat transfer performance, it is necessary to have a height adjustment mechanism for each coil. It was an important factor to ensure the uniformity of performance.

In addition to the above, in various industrial fields, even if the mounting intervals and mounting positions of parts are accurately adjusted, and even if they are tightened with bolts or the like, the adjusted size does not change and the mounting position or the like can be held for a long period of time. Moreover, it is desired in many situations that the adjustment operation can be easily performed.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a space adjusting spacer and a space adjusting spacer group in which the space and position can be easily adjusted and with high accuracy.

[0005]

According to a first aspect of the present invention, there is provided a space adjusting spacer comprising a pair of semi-circular rings which are bisected through the center of a circular ring having a hole for inserting a bolt or the like in the center. The two semi-circular rings can be engaged with each other by the convex engagement portion and the concave engagement portion formed at both ends of each semi-circular ring. For adjusting the gap spacer group according to claim 2 is a spacer according to claim 1, characterized by comprising a plurality of sets of thicknesses different.

According to the first aspect of the present invention, since the spacer shape is a semicircular ring, each spacer can be taken in and out by slightly loosening it without completely removing the bolt for tightening. Therefore, since it is easy to increase or decrease the number of spacers, it is possible to easily adjust the spacing or the mounting position. Also, once bonded two semicircular ring convex form engaging portion and the concave engaging portion, without falling or deviation during tightening by fastening bolts, or when loosening the fastening bolts Easy adjustment work. Moreover, artificial detachment can be done easily. According to the invention of claim 2 , by appropriately selecting and combining spacers having different thicknesses, a desired space can be obtained, so that the space adjustment becomes easier and the adjustment accuracy can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. 1A is a plan view of a spacer according to an embodiment of the present invention in a separated state, FIG. 1B is a plan view of a combined state, and FIG. 2 is used for adjusting a height of a coil. It is a front view which shows a spacer.

As shown in FIG. 1, the spacer 1 of this embodiment is composed of two semi-circular rings 2 and 3 which are bisected through the center of a circular ring. (A) figure is a state of being divided into two, and (B) figure is a state of being connected. (B) As shown in the figure, the spacer 1 has a circular shape as a whole,
A bolt insertion hole 4 is formed concentrically with the center thereof. The bolt insertion hole 4 also becomes half holes 5 and 6 when the spacer 1 is divided into two. A convex engagement portion 7 and a concave engagement portion 8 are formed at both ends of each semicircular ring 2, 3. The convex engagement portion 7 and the concave engagement portion 8 are fitted to the concave engagement portion 8 and the convex engagement portion 7 of the counterpart semicircular rings 3 and 2, so that the semicircular rings 2 and 3 are joined together. Combined with each other. Further, the insertion / removal can be easily performed by approaching / separating in the direction perpendicular to the paper surface.

In FIG. 2, B is a support beam and C is a part of a coil. Reference numeral 10 is a fitting for suspending the coil C on the support beam B. The mounting bracket 10 has a bolt 11 and two nuts 12 and 13, and the bolt 11 is passed through a hole of a mounting member 14 on the coil C side and a hole formed in the support beam B. And
A spacer group 1S in which an appropriate number of spaces 1 are combined is inserted between the top surface of the mounting member 14 and the lower surface of the support beam B, and a nut 12, which constitutes a so-called double nut,
The bolt 11 is fastened by 13. When each of the spacers 1 constituting the above-mentioned spacer group 1S is manufactured, for example, in three types having thicknesses of 2, 3, 5 mm, it is possible to sufficiently adjust the coil height accuracy tolerance of about +10 mm. The thickness of the spacer 1 described above is an example, and a thinner one or a thicker one may be arbitrarily selected according to the purpose of use. Furthermore, the types of thickness are not limited to three types, and may be two types or four or more types.

According to this embodiment, the semicircular rings 2, 3
Since the spacers 1 are used, the spacers 1 can be taken in and out by simply loosening the bolts 11 without completely removing the tightening bolts 11, and the number of spacers 1 can be easily increased or decreased, so that the spacing or the mounting position can be easily adjusted. . In short, since the worker only adjusts the number of spacers 1 by tightening and loosening the upper double nuts 12 and 13, work efficiency is very good. Further, when the two semicircular rings 2 and 3 are coupled to each other by the convex engagement portion 7 and the concave engagement portion 8, the fastening bolt 11
The adjustment work can be easily performed without misalignment when tightened with or without dropping when the fastening bolt 11 is loosened.
Moreover, artificially the removal can be done easily. Therefore, when assembling the coil of the fluidized bed type reactor as shown in FIG. 3, in order to match the level of the lower surface of each coil C, each fitting 1
The height of the entire coil C can be adjusted easily and accurately by adjusting the number of the spacers 1 of 0. Therefore, it is possible to improve the coil assembling accuracy in a fluidized bed reactor characterized by a structure in which a cooling and heating coil is mainly incorporated in the pressure vessel, and obtain more uniform heat transfer performance.

[0011]

According to the first aspect of the present invention, since the semicircular ring is used, the spacer can be taken in and out by simply loosening it without completely removing the bolt for tightening. Therefore, since it is easy to increase or decrease the number of spacers, it is possible to easily adjust the spacing or the mounting position. Also, once bonded two semicircular ring convex form engaging portion and the concave engaging portion, without falling or deviation during tightening by fastening bolts, or when loosening the fastening bolts Easy adjustment work. Moreover, artificially the removal can be done easily. According to the invention of claim 2 , by appropriately selecting and combining the spacers having different thicknesses, the desired spacing can be obtained, so that the spacing can be adjusted more easily and the adjustment accuracy can be improved.
