Description

[Detailed explanation of the invention] Conventionally, tankers transporting chemical liquids such as sulfuric acid and caustic soda have had a loading tank with a circular cross section and rubber, etc. glued to the inside surface, installed in the hold. Because the tanks are circular, a large hull volume is required, and the liquid loaded in the tanks moves with the rocking of the ship, resulting in poor stability. However, the weight of the tank increases and the piping work is labor-intensive, and the work of gluing corrosion-resistant rubber to the inside of the tank and adding mud also requires a lot of time and effort. Ta.

In order to eliminate the above-mentioned drawbacks, the present invention has been developed by installing a partition plate inside a tank with a square cross section to separate the inside of the tank, spraying FRP on the inner surface, and fixing reinforcing ribs on the outer circumferential surface. This tank is characterized by its light weight, good stability when loaded with liquid, no need for corrosion-resistant treatment, and easy installation of collection piping.

Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

The bottom plate 1 is tilted diagonally downward from both ends toward the center line, and the top plate 2 is tilted diagonally downward from the center line toward both ends, so that both ends of the bottom plate 1 and the top plate 2 are connected. side plate 3
, 3' are reduced in width, and a front plate 4 and a rear plate 5 are provided consecutively on the front and rear end surfaces, and a corrugated partition plate 6 is provided consecutively on the inner surface of both side plates 3, 3' near the front. A corrugated partition plate 6' is connected to the center of the corrugated partition plate 6 and the center of the inner surface of the back plate 5, and the inside is divided into a first tank chamber 7a, a second tank chamber 7-b, a third tank chamber 7-c, etc. Reinforcement ribs 8 are placed on the outer circumferential surface at appropriate intervals.
, 8' are fixed, a reservoir 9 is recessed in the bottom plate 1 of each tank chamber, and the inner surface is sprayed with FRP to constitute a loading tank 10.

In the figure, 11 is a ship, 12 is an inner bottom plate of a hold, 13 is a floor plate, and 14 is a wave frame.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The loading tank 10 of the present invention is installed in the hold of a ship 11 to load and transport chemical liquids such as sulfuric acid and caustic soda.
The rear both sides of tank chamber 7-31 are connected to the second tank chamber 7-b1 and the third
By dividing the tank chamber 7-c into the tank chamber 7-c, even if the ship body rocks, the liquid inside does not shift to one side, and the stability of the ship 11 during voyage can be improved.
The inner surface of each tank chamber is sprayed with FRP, so there is no need to spend time on corrosion-resistant spraying.If the inner surface of each tank chamber is lined with rubber, only sulfuric acid can be loaded, but in the case of FRP processing, There are no restrictions on the types of chemical liquids that can be loaded, and the capacity of the hold is fully utilized compared to circular tanks, and the tank is relatively light in weight. Piping is carried out using the circumferential side of the cargo tank, and a pump installed on the inner bottom plate of the hold enables efficient cargo handling work, eliminating the drawbacks of circular or container-type cargo tanks. This provides various remarkable effects as described above, such as being able to plan efficient transportation of chemical liquids.
