Abstract

The invention relates to a low temperature vessel inner tank reinforcing device comprising intensive reinforcing rings and sparse reinforcing rings. The intensive reinforcing rings are arranged nearby the middle position inside a tank body, and the sparse reinforcing rings are arranged nearby the shell cover position inside the tank body. The low temperature vessel inner tank reinforcing device further comprises support reinforcing rings, the support reinforcing rings are arranged inside the tank body and are used to support supporting positions of an outer tank, the support reinforcing rings are arranged intensively in the supporting and connecting eight point supporting positions of an inner tank and the outer tank, and stiffness of the tank body in the position is improved. The low temperature vessel inner tank reinforcing device is strong in stability and simple in manufacturing technology.

Description

Low-temperature (low temperature) vessel inner canister stiffening device
Technical field
The invention belongs to tank body safety technique field, relate to a kind of low-temperature (low temperature) vessel inner canister stiffening device, relate in particular to a kind of low-temperature (low temperature) vessel inner canister stiffening device for cryogenic liquides such as conveying liquified natural gas.
Background technique
Inner canister inside at the low-temperature (low temperature) vessel of the cryogenic liquides such as conveying liquified natural gas is provided with a large amount of stiffening rings, bears external pressure when being used for the vacuum leak hunting of inner canister helium mass spectrum, keeps the stability of external pressure of tank body.At present when inner stiffening ring is set, mainly contain two problems: the firstth, when arranging, do not consider the support zone between tank body inner canister and the outer tank, for example 8 Support Positions are located, often relatively weaker, tank body is relatively poor in this place's rigidity, because the distortion of interior tank often causes 8 support place sedimentations, bring potential safety hazard for the transportation of cryogenic media; The secondth, present inside stiffening ring is arranged the equidistantly layouts that adopt more, and the mode of this inner canister internal placement stiffening ring is so that stiffening ring quantity is more, and the costs such as follow-up welding, non-destructive inspection are high.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technique, the invention provides the strong and simple low-temperature (low temperature) vessel inner canister of the manufacturing process stiffening device of a kind of stability.
Technical solution of the present invention is: the invention provides a kind of low-temperature (low temperature) vessel inner canister stiffening device, comprise the sparse stiffening ring that is arranged near the intensive stiffening ring in tank interior intermediate portion and is arranged near the position of tank interior end socket, its special way is: described low-temperature (low temperature) vessel inner canister stiffening device also comprises and is arranged on the support reinforcing circle that tank interior be used for to support support place of outer tank, this support reinforcing circle is located intensive layout in 8 Support Positions of inner canister and outer tank support and connection, improves the tank body rigidity of this position.
Above-mentioned support reinforcing circle is one or multi-channel.
When above-mentioned support reinforcing circle was multiple tracks, described multiple tracks support reinforcing circle was support place that equidistantly is arranged in for supporting outer tank.
When above-mentioned support reinforcing circle was multiple tracks, described multiple tracks support reinforcing circle was that non-equidistance is arranged in support place that is used for supporting outer tank.
The cross section of above-mentioned intensive stiffening ring, sparse stiffening ring and support reinforcing circle all is channel-section steel, angle steel or T bar.
Advantage of the present invention is:
The present invention adopts non-equidistance to arrange the principle of stiffening ring, and to its extension of carrying out, except needing the sparse stiffening ring in intensive stiffening ring and end socket place in the middle part of the tank body, support place in inner canister and outer tank also is provided with intensive stiffening ring, efficiently solve the tank body problem on deformation at inner canister and outer tank link position place, so that tank body resisting to lose stability under external pressure ability is strong, tank body circularity is controlled easily, promoted the Security and stability of tank body.Simultaneously, the various ways such as channel-section steel, angle steel, T bar can be adopted in the cross section of inner stiffening ring provided by the present invention, have further strengthened stiffening effect.

Fig. 1 is the schematic cross-section of low-temperature (low temperature) vessel inner canister stiffening device provided by the present invention;
Fig. 2 is the cut-away section structural representation of low-temperature (low temperature) vessel inner canister stiffening device provided by the present invention;
Wherein
The 1-inner canister; The 2-intermediate portion; The 3-end socket; 4-supports support place of outer tank; The 5-stiffening ring.
Embodiment
Referring to Fig. 1 and Fig. 2, the invention provides a kind of low-temperature (low temperature) vessel inner canister stiffening device except the intensive stiffening ring 5 that comprises the tank interior intermediate portion 2 that is arranged on inner canister 1 and the sparse stiffening ring 5 that is arranged on tank interior end socket 3 positions, also comprise being arranged on the support reinforcing circle 5 that tank interior is used for supporting support place 4 of outer tank.The present invention is more sparse near end socket 3 places, near tank body middle part comparatively dense, and is provided with separately support reinforcing circle 5 near support place, fully strengthened the global stability of tank body.
It is one or multi-channel that support reinforcing circle 5 can adopt, and when support reinforcing circle 5 was multiple tracks, multiple tracks support reinforcing circle 5 was equidistant or non-equidistance is arranged in for support place 4 of supporting outer tank.
It is the steel in channel-section steel, angle steel, T bar or other cross sections that the cross section of intensive stiffening ring 5, sparse stiffening ring 5 and support reinforcing circle 5 can be adopted.
