Abstract

The utility model discloses a liquefied natural gas transportation tank body which comprises an outer tank (1), an inner tank (2) and a group of reinforcing rings (3), wherein the inner tank (2) is arranged in the outer tank (1); and the group of reinforcing rings (3) is arranged on the outer wall of the outer tank. The liquefied natural gas transportation tank body has the advantage that the reinforcing rings are arranged on the outer wall of the outer tank, so that the effective space in the outer tank is increased, the inner diameter of the inner tank is further increased and the cargo loading capacity of the liquefied natural gas transportation tank body is increased.

Description

A kind of LNG Liquefied natural gas transportation tank body

Technical field

The utility model relates to a kind of LNG Liquefied natural gas transportation tank body.

Background technique

At present; In the existing LNG Liquefied natural gas transportation tank body; Mainly be made up of outer jar, interior jar and one group of stiffening rib, one group of stiffening rib is installed on the inwall of outer jar, and its deficiency is that one group of stiffening rib is installed on the inwall of outer jar; Effective volume in the LNG Liquefied natural gas transportation tank body is reduced, and useful load just is limited.

Summary of the invention

The purpose of the utility model is exactly in the present existing LNG Liquefied natural gas transportation tank body; Mainly form by outer jar, interior jar and one group of stiffening rib; One group of stiffening rib is installed on the inwall of outer jar, and its deficiency is that one group of stiffening rib is installed on the inwall of outer jar, and the effective volume in the LNG Liquefied natural gas transportation tank body is reduced; The deficiency that useful load just is limited, and a kind of LNG Liquefied natural gas transportation tank body is provided.

The utility model comprises outer jar, interior jar and one group of stiffening ring, and interior jar is installed in outer jar, and one group of stiffening ring is installed on the outer tank wall.

It also has two groups of local stiffening ribs, and stiffening ring both sides local thickness reduces, and two groups of local stiffening ribs are installed in respectively on the outer wall of outer jar both sides, and is positioned at stiffening ring both sides local thickness and reduces the place.

Two groups of local stiffening ribs are one with outer jar.

The utility model has the advantages that: stiffening rib is installed on the outer tank wall, has increased the useful space in outer jar, and then increased interior jar of internal diameter, strengthened the Deadweight cargo capacity of LNG Liquefied natural gas transportation tank body.

Embodiment

Like Fig. 1, shown in Figure 2, the utility model comprises outer jar 1, interior jar 2 and one groups of stiffening rings 3, and interior jar 2 is installed in outer jar 1; Stiffening ring 3 thickness are L1 ㎜; With outer jar 1 external diameter by 2500 original ㎜ reduce to (mm of 2500-2 * L2), one group of stiffening ring 3 is installed on the outer tank wall, and stiffening ring 3 both sides regional area A thickness are decreased to L2mm (L2＜L1); Two groups of local stiffening ribs 4 are installed in respectively on the outer wall of outer jar 1 both sides, and are positioned at one group of stiffening ring, 3 both sides regional area A thickness and reduce the place.Interior jar 2 inside radius is enlarged (L1-L2) mm.

Two groups of local stiffening ribs 4 can be one with outer jar 1.

In the expandable principle of jar internal diameter: because one group of stiffening ring 3 is moved on the outer wall by former being installed on outer jar 1 the inwall, thereby increased the useful space in outer jar 1, and then jar internal diameter in can increasing, added the volume of imperial palace jar.

Because with moving on the outer wall on the inwall of one group of stiffening ring 3 by jar 1 outside former being installed in; The LNG Liquefied natural gas transportation tank body normal width 2500mm that has exceeded national regulation; Therefore must reduce by outer jar 1 external diameter,, then can not add the volume of imperial palace jar 2 if reduce the requirement that L1mm satisfies the LNG Liquefied natural gas transportation tank body normal width 2500mm of national regulation; If (L2＜L1) satisfies the requirement of the LNG Liquefied natural gas transportation tank body normal width 2500mm of national regulation to be reduced to L2mm; Then can strengthen the useful space in outer jar, thereby just can add inside radius (L1-L2) mm of imperial palace jar, strengthen the Deadweight cargo capacity of LNG Liquefied natural gas transportation tank body.

Because outer jar 1 outer radius only reduces (L1-L2) mm; And under the immovable situation of the thickness of one group of stiffening ring 3; The requirement that then can exceed the LNG Liquefied natural gas transportation tank body normal width 2500mm of national regulation; Thereby reduce thickness (L1-L2) mm at the local A place of one group of stiffening ring 3, just can reach the requirement of the LNG Liquefied natural gas transportation tank body normal width 2500mm of national regulation.

After reducing the thickness at local A place of one group of stiffening ring 3; Certainly will reduce the outer jar of 1 local external-pressure resistance at the local A place of one group of stiffening ring 3; So one group of local stiffening rib 4 will be installed, on outer jar of 1 part at the local A place of stiffening ring 3 with the outer jar 1 local external-pressure resistance at the local A place of improving one group of stiffening ring 3.

Claims

1. a LNG Liquefied natural gas transports tank body, and it comprises outer jar (1), interior jar of (2) and one group of stiffening ring (3), in jar (1), it is characterized in that one group of stiffening ring (3) is installed on the outer tank wall outside interior jar (2) are installed in.

2, a kind of LNG Liquefied natural gas transportation tank body according to claim 1; It is characterized in that it also has two groups of local stiffening ribs (4); Stiffening ring (3) both sides local thickness reduces; Two groups of local stiffening ribs (4) are installed in respectively on the outer wall of outer jar (1) both sides, and are positioned at the local A thickness in stiffening ring (3) both sides and reduce the place.

3, a kind of LNG Liquefied natural gas transportation tank body according to claim 2 is characterized in that two groups of local stiffening ribs (4) and outer jar (1) are one.
