Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-layer vertical tank capable of storing several kinds of contents in a small site.

[0002]

[Prior art]

 The conventional tank is formed as a single unit and is installed independently for each stored content. Therefore, when storing several types of contents, there was a problem that a large site was required to install multiple tanks.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention has been made to solve the above problems, and an object thereof is to provide a multi-layer vertical tank capable of storing several kinds of contents in a small site.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that the inside of a vertical cylindrical tank is partitioned into multiple layers by a downwardly swelling curved partition plate.

[0005]

[Action]

 According to the above configuration, since the vertical cylindrical tank is partitioned in multiple layers by the partition plate, it is possible to store several kinds of contents in a narrow site. In addition, since the partition plate is formed in a curved surface that bulges downward, the strength is high, and the contents can be independently held in each layer.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a foundation on which two tanks 3 and 4 of the same height are arranged side by side via support legs 2. On the other hand, the tank 3 on the right side consists of a normal vertical cylindrical tank, and a curved bottom portion 5, a cylindrical body portion 6 divided in the height direction, and a curved top portion 7 are welded together. It is formed by connecting. A vent 8 and a top manhole 9 are provided on the top 7 of the tank 3, and a ladder 10 is mounted inside. A side manhole 11 is provided on the lower side of the tank 3, and an inlet 12 and an outlet 13 for the contents are provided on the bottom 5.

The other (left) tank 4 is composed of a vertical cylindrical tank having a multi-layer structure, and the inside of the tank is divided into multi-layers by curved curved partition plates 19 and 20. In the illustrated example, three cylindrical tanks 14, 15, 16 are vertically formed by stacking so that the bottom portions 19, 20 of the upper tanks 15, 16 serve as partition plates. Specifically, the lower tank 14 has a curved bottom portion 17, a cylindrical cylindrical portion 18 divided into a plurality in the height direction, and a curved bottom portion 19 of the middle tank 15 in the height direction. It is formed by overlapping and connecting by welding. The tank 15 in the middle portion is formed by welding a bottom portion 19, a cylindrical portion 20 divided into a plurality in the height direction, and a curved bottom portion 21 of the upper tank 16 in the height direction and connecting them by welding. Has been done. The upper tank 16 is formed by connecting a bottom portion 21, a cylindrical portion 22 divided into a plurality in the height direction, and a curved top portion 23 in the height direction so as to be connected by welding.

The bottom 17 of the lower tank 14 is provided with an inlet 24 and an outlet 25 for the contents, a side manhole 26 on the side, a vent 27 on the upper side and the contents of the tank 15 in the middle. Each outlet 28 is provided. An inlet 29 and a side manhole 30 for the contents are provided on the lower side of the middle tank 15, and a vent 31 and an outlet 32 for the contents of the upper tank 16 are provided on the upper side. A vent 33 and a top manhole 34 are provided at the top 23 of the upper tank 16, and an inlet 35 and a side manhole 36 for contents are provided at the bottom.

Further, the left and right tanks 3 and 4 are provided with corridors 37a to 37d located below the manholes 26, 30, 34 and 36, respectively, and the corridors 37a to 37d on each floor are surrounded by a staircase 38a. Tied by ~ 38c. 39 is a stairway connecting the ground and the first corridor 37a.

According to the multi-layer vertical tank 4 having the above structure, however, since one vertical tank is vertically divided into three layers by the partition plates 19 and 20, three types of vertical tanks can be used in a narrow site. The contents can be stored in any combination. Further, since the partition plates 19 and 21 for partitioning the inside of the tank are formed by the curved bottom portions, the strength is high, the contents can be independently held in each layer, and the contents in the lower tank are empty. However, the weight of the contents can be sufficiently supported.

Further, as in the embodiment, the multilayer vertical tank 4 and the normal vertical cylindrical tank 3 are juxtaposed side by side, and both tanks 3 and 4 are connected by the corridors 37a to 37d. And excellent in earthquake resistance. For example, even if the center of gravity of the multi-layer vertical tank 4 becomes high due to the empty contents of the lower tank, it will not fall down due to an earthquake or the like.

It should be noted that the embodiment shows the case where the multilayer vertical tank 4 has a three-layer structure, but the number of layers is not limited. Further, although the embodiment shows the case where the multi-layer vertical tank 4 and the normal vertical tank 3 are combined, both may be a multi-layer vertical tank, and the number and arrangement of the vertical tanks arranged in parallel. Is optional.

[0014]

[Effect of device]

 In short, according to the present invention, since the vertical cylindrical tank is partitioned in multiple layers by the partition plate, several kinds of contents can be stored in a small site, and the partition plate has a curved surface bulging downward. Since it is formed, it has high strength and each layer can hold the contents independently.
