Description

A storage tank of cylinder type and the manufacturing method

The present invention relates to a cylindrical storage tank and a manufacturing method thereof, and more particularly, to a cylindrical storage tank and a manufacturing method thereof that is easy to install and repair.

A storage tank is a means for storing powdered raw materials such as oil and cement, and living and factory water, and a storage tank (water tank) for storing water for use as a factory water, in particular, can withstand considerable water pressure. It must be made.

However, currently used water storage tanks are usually difficult to manufacture because the fastening of a plurality of panels by fastening bolts, and the coupling part is weak and has a weak end to the hydraulic pressure. It also has a closed end where all bolts of the panel must be removed in order to replace the pad of the leaked part when a leak occurs.

Therefore, a technique to solve this problem is a LIPP type water storage tank manufacturing method developed in Germany. In this method, in forming a water storage tank, one connected metal plate is spirally rolled by a molding apparatus, and the edges of the metal plate are separated from each other. Combining to form a cylindrical body of a certain length, in order to use the cylindrical body as a water storage tank, it is necessary to combine the upper plate and the bottom plate of the same diameter on the top and bottom. However, since the top and bottom of the cylinder is inclined, it is not easy to combine the top plate and the bottom plate.

In addition, the LIPP type water storage tank as described above has a diameter of only 3 m in the cylindrical body that can be manufactured by the molding machine, so in order to produce a large water storage tank having a diameter of more than 3 m, the molding machine must be refitted according to its size. It has to be manufactured so that it has a very uneconomical disadvantage.

In particular, the LIPP type water storage tank works on the cylindrical body with the finishing work such as top plate and ladder installation completely completed. Inevitably, the increase in the manufacturing cost of the water storage tank has a closed end.

In addition, in the LIPP type water storage tank, the edges of the metal plates overlap each other in forming the metal plate into a spiral cylindrical body. It flows down through the gaps and eventually has a closed end that cannot easily find out which part is leaking.

As described above, the conventional LIPP type water storage tank is easy to manufacture and has strong advantages in water pressure, but has various disadvantages as described above.

Therefore, the manufacturing method of the present invention is also to form a cylindrical body by rolling the metal plate by a molding apparatus, but not formed by spirally rolling like a conventional LIPP type water tank, the top plate and a plurality of cylindrical units, which are provided with the necessary structures in advance, By combining the lower plate in order to form a storage tank, it is easy to combine the upper plate, cylindrical unit, and lower plate, and does not have to work high altitude, and it can be manufactured by freely adjusting the diameter of the cylindrical body, and identify the leak point when leaking. It is very easy to do.

In addition, the present invention storage tank produced by the above method is the upper plate having a vent pipe and the entrance and exit, the upper cylindrical unit to which the upper plate is mounted, the upper band for covering the coupling portion of the upper plate and the upper cylindrical unit And one or more intermediate cylindrical unit to which the upper cylindrical unit is mounted and coupled, a lower cylindrical unit to which the intermediate cylindrical unit is coupled and mounted, and a plurality of portions for covering the coupling portion of the upper cylindrical unit and the intermediate cylindrical unit and the lower cylindrical unit. Two intermediate bands, and a lower plate coupled to the bottom of the lower cylindrical unit.

FIG. 3 shows the upper cylindrical unit 20 separated from the cylindrical units forming the body of the storage tank 1 in the present invention, and all the cylindrical units 20 have the same structure.

That is, by cutting, bending, and rolling a metal plate of a predetermined width, the edges of both ends are cut out, and the edges of the both ends and the upper and lower ends are bent at right angles, thereby bending the bent parts 21, 22, and 23. A cylindrical body 20A to be provided, a holding pipe 25 formed at the inner center of the cylindrical body 20A, and supporting the upper plate 10, welded to the side surface of the holding pipe 25, It consists of a ladder 26 for workers to move up and down. When the storage tank 1 of the present invention stores a material requiring heat insulation, the outer circumferential surface of the cylindrical body 20A may be wrapped with a heat insulating material 24, and the heat insulating material 24 may be formed by a cylindrical body (B). It is coupled to the outer circumferential surface of 20A). The heat insulator 24 used flame retardant glass fiber.

In addition, in order to use the present invention storage tank 1 as a water storage tank, a water supply pipe 20a must be formed in the upper cylindrical unit 20, and a drain pipe 50a must be formed in the lower cylindrical unit 50.

The bent portion formed in the cylindrical body is a very important configuration in the present invention to enable the operation by placing the upper cylindrical unit on the lower cylindrical unit, the lower cylindrical unit is formed because the bent portion is bent at a right angle to the upper and lower ends of the cylindrical body With the upper cylindrical unit on top, it is very convenient to weld and bolt the work.

The storage tank 1 of the present invention may combine the upper plate, each cylindrical unit and the lower plate by welding as shown in FIG. 2, but the upper plate 10 and each cylindrical unit 20, 40, 50, as shown in FIG. 5. ) And a seal (sealing material) at the edge of the lower plate 70 may be coupled by fastening with a bolt 90a and a nut 100a from the outside.

However, at this time, the coupling portions of the upper plate 10 and the cylindrical units 20, 40, 50 and the lower plate 70 are opened from the inside to increase the risk of water leakage. Units (20, 40, 50) at the inner edge of the coupling portion and the coupling portion of the cylindrical unit (50) and the lower plate (70), the L-assistance support (140) with the bolt (90b) and the nut (100b) By fastening, it can also be configured to prevent the coupling portion from opening due to water pressure.

The band 50a used in this case may be different from the band 50 used when the structure is welded to the cylindrical body as shown in FIG.

Or it is configured to be coupled by bolting.

The present invention describes a method of manufacturing a storage tank (1) for use in applications that do not require insulation, and when the storage tank for storing water is required, heat insulation is required, and at the same time, the cylindrical body is combined. It may further comprise the step of attaching the insulation 24 by the band in sequence.

That is, the cylindrical units (20, 40, 50) in which the heat insulating material is first formed after the cylindrical bodies are combined, the step of wrapping the heat insulating material on the cylindrical body and combining the bands in a band is repeated for each cylindrical unit is combined.

In other words, when the cylindrical body 20A of the upper cylindrical unit 20 and the cylindrical body 40A of the intermediate cylindrical unit 40 are joined by welding or bolting, the upper cylindrical body 20A and the intermediate cylinder are combined. It is to be sequentially coupled to the sieve 40A by a band. Of course, the insulation may be adhered or attached to the cylinder in advance before joining the band for convenience.

In addition, the holding pipe 25 formed in the inner center of the cylindrical body 20A to support the upper plate 10 is also coupled in order from the bottom of the upper plate 10 in the joining order, and thus to the lower plate 70. Are combined.

A ladder may be coupled to the connector 110 between the band and the band to form an external ladder 120.

As such, the present invention produces the storage tank by sequentially combining the upper plate, the cylindrical unit, and the lower plate on which all the structures are already installed. Therefore, the welding or bolting operation, the insulation material attaching, at the height of one cylindrical unit, that is, about 1.3 to 1.5 m, Since the band fastening work is performed, the workers can do all the work very comfortably, and thus, there is no need for high-working work, thereby reducing the production cost.

As such, the present invention combines the upper plate, the plurality of cylindrical units, and the lower plate, which are pre-equipped with all structures, to form a storage tank by sequentially combining the upper plate, the cylindrical unit, and the lower plate at a low height. Because it is formed, it is very easy for the worker to work, and it is possible to reduce the manufacturing cost significantly because it does not have to work high altitude, and the production capacity can be adjusted freely because only the diameter of the cylindrical body can be manufactured. Since each cylindrical unit is combined in a separate state, it is very easy to identify the leak point when leaking, and has an effect of reducing the construction period.
