The present invention relates to a F. R. P hot water tank in which a boiler and a regenerative electric water heater tank are formed of synthetic resin F. R. P to facilitate pressure treatment, life extension, and use.

Conventionally, hot water tanks for boilers are usually made of metal, which is somewhat improved due to rust, and has been used in stainless steel materials such as stainless steel pipes for water heaters. In the case of debris and impurities and the hot water tank of the water heater was repeatedly heated, there was a defect that the rust occurs. Despite these defects, there was an expensive end point and an uneconomic problem that could not be used for a long time.

The present invention has been made in order to achieve the desired purpose as a result of various studies and experiments over a long period of time to solve and supplement the conventional drawbacks as described in detail by the accompanying drawings as follows.

In the water heater equipped with the cold / hot water pipes (11), (12), the temperature controller (13), and the heater (14), and covered with a fin (16), and the tub and the disconnection lamp (15), the inner case (4) The semi-curved curved portions 6, 6 ', which form the upper opening 7 and the wastewater outlet 8, are formed at the upper and lower ends, and the middle portion is bent the corrugated portion 5, and the outer surface is joined with a heat insulating layer 2. The upper and lower flanges 9 and 10 are supported by being connected as the bands 3 and 3 'so as to be supported by the outer case 1.

The effect of this paper is explained as follows.

When used, it is used together with a normal boiler hot water tank. Indirect heating as a heater 14 not only extends the life span 3-4 times as compared with the conventional direct heating type, but also has no pollution and uses no hot water inside the fuel. When pressure is generated, the safety valve operates to eliminate the risk when pressure is exceeded. However, when pressure is generated, creases (5) are formed at the upper and lower ends of the inner case (4). The upper and lower ends constitute semicircular upper and lower curved portions 6 and 6 'so as to be ideally opposed to the generation of pressure and endure.

In addition, the urethane foam suspended insulation layer (2) is reinforced by forming joint bands (3) and (3 ') at the upper and lower ends to provide firm adhesion. The lower wastewater outlet (8) completely discharges residual wastewater when cleaning. The upper and lower connection support flanges 9 and 10 serve to support the weight of the water to be effectively transmitted to the outer case 1 when the water is filled in the inner case 4.

The outer case (1) and the inner case (4) are molded as FR P material made of glass fiber, organic fiber, etc. as a reinforcing material, and generally, the part where the corrosive liquid contacts is increased to 80-100% of resin content, thereby increasing acid and alkali. Corrosion resistance against oil, lead, solvents, etc. It is very light in weight, but it is easy to transport, install and attach because of its high strength-to-weight ratio, and it is light and strong for manufacturing large equipment, rank, pipe pollution prevention, chemical equipment and other industrial equipment, especially vinyl chloride, As it is a thermosetting resin other than thermoplastic resins such as polyethylene, it does not soften or deform at high temperatures, and does not crack or crack at low temperatures, and thus has excellent heat resistance. It is small enough and has good thermal insulation, so it does not need to keep warm or cold. In addition, since it does not use metal, there is no metal ion dissolution in the contents, no quality change occurs, and it is semi-transparent so that the liquid level (water level) can be seen from the outside. In addition, various molding methods such as hand lay-up and filament winding molding are developed according to the shape and use of sexual products, and even large equipments or complex moldings are molded at once and are difficult to transport by field construction. It is also possible to manufacture, so it is easy to mold regardless of small, medium and large size of FR P hot water tank.

This proposal is effective to extend the lifespan 3-4 times compared to the conventional hot water tank.

Claims (1)

As shown in the figure, in the water heater equipped with the cold and hot water pipes 11, 12, the temperature controller 13, and the heater 14, and covered with a fin 16, the tub and the disconnection lamp 15 are installed. In the upper and lower ends of the inner case 4, the semi-curved curved portions 6 and 6 'forming the upper opening 7 and the wastewater outlet 8 are formed, and the interruption portion is formed to bend the corrugated portion 5 so as to insulate the insulating layer on the outer surface. An FR P hot water tank in which (2) is formed as a joint band (3) and (3 '), and the upper and lower flanges (9) and (10) are supported to be supported by the outer case (1).
