円輪状の底板６とから形成されている。In FIG. 1, reference numeral 1 denotes a rotary storage tank, which is composed of an annular storage tank 2 and a rotary drive device 3 for rotating the storage tank 2 around its own axis. The rotary drive device 3 is a known device including a motor and a speed reducer. The storage tank 2 has a cylindrical large-diameter outer shell plate 4, a small-diameter inner shell plate 5 arranged coaxially inside the outer shell plate 4, and a gap between the outer shell plate 4 and the inner shell plate 5. And a circular ring-shaped bottom plate 6 fixed to the bottoms of these members 4 and 5 so as to close them.

要の構造物強度が得られる。As shown, both the outer shell plate 4 and the inner shell plate 5 are made of corrugated steel plates. Since the powder and granules are stored in the space S between the outer shell plate 4 and the inner shell plate 5, the powder and granules exert an internal pressure on the outer shell plate 4 and an external pressure on the inner shell plate 5. However, since both body plates 4 and 5 are made of corrugated steel plate, the section modulus is much larger than that of the conventional flat body plate made of steel plate, and the material strength is much larger due to the plastic working called corrugation. ing. Therefore, it is not necessary to fix the reinforcing ribs by welding as in the conventional case, the weight is significantly reduced, and the required structural strength is obtained.

る。Each body plate is generally formed by connecting a plurality of corrugated steel plates (referred to as body plate elements) which are curved in a partially cylindrical shape. The main body plates 4 and 5 also have no problem in using the method. The body plate elements may be connected to each other by welding as in the conventional case, or bolts may be used. When using bolts, the edges of adjacent body plate elements are overlapped by a certain size and holes are drilled to match the two, and then bolted, or the edges of adjacent body plate elements are butted. Alternatively, a separate connecting plate may be superposed on both elements, and holes corresponding to the connecting plate and both elements may be bored and bolted. For the body plate element, for example, in a storage tank having an outer body diameter of 23 m and an inner body diameter of 9 m, in the case of an outer body plate, the entire circumference is divided into 24 to 36 at intervals of 10 to 15 °. In the case of the body plate, the size of the entire circumference divided by 8 to 12 every 30 to 45 ° can be used.

The bottom plate 6 is curved so that the cross-sectional shape cut along a vertical plane including an arbitrary radius of the storage tank 2 has a substantially partially circular shape that bulges upward. By forming the bottom plate 6 in this way, the structure strength is improved. Thereby,
Unlike conventional products, it is not necessary to fix a large amount of reinforcing ribs on the bottom plate under welding, and a lighter weight and almost the same strength bottom plate can be completed with far fewer manufacturing steps.

The bottom plate elements may be connected to each other by welding as in the conventional case, or bolts may be used. When bolts are used, the edges of adjacent bottom plate elements are slightly overlapped with each other and holes corresponding to the two are drilled to be bolted, or the edges of adjacent bottom plate elements are butted against each other. The connecting plate of the body may be superposed on both elements, and holes may be drilled to match the connecting plate and both elements, respectively, and bolted. As the bottom plate element, for example, a fan-shaped element having a size in which the entire circumference is divided into 24 to 36 at intervals of 10 to 15 ° (so-called fan opening angle) can be used.

However, it is preferable to use bolt fasteners to improve workability, reduce manufacturing man-hours, and reduce manufacturing costs.
