Abstract
The utility model relates to an inner tank reinforcement device for a low-temperature container. The inner tank reinforcement device comprises a dense reinforcement ring close to the middle inside a tank body, a sparse reinforcement ring arranged close to an end socket inside the tank body, and supporting reinforcement rings arranged inside the tank body and used for supporting the supporting positions of an outer tank, wherein the supporting reinforcement rings are densely arranged at 8 supporting positions for supporting and connecting an inner tank and the outer tank, so that the rigidity of the tank body at the positions can be improved. The utility model provides the inner tank reinforcement device with high stability and simple manufacturing technology.
Description
Technical field
The utility model belongs to tank body safety technique field, relates to a kind of low-temperature (low temperature) vessel inner canister stiffening device, relates 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, do not consider the support zone between tank body inner canister and outer tank when arranging, for example 8 Support Positions are located, often weaker, tank body is relatively poor in this place's rigidity, due to the distortion of interior tank, often cause 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 makes stiffening ring quantity more, and the costs such as follow-up welding, non-destructive inspection are high.
The model utility content
In order to solve the above-mentioned technical problem that exists in background technique, the utility model provides a kind of stability the strong and simple low-temperature (low temperature) vessel inner canister of manufacturing process stiffening device.
Technical solution of the present utility model is: the utility model 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 the tank interior intermediate portion and is arranged near the position 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 improves the tank body rigidity of this position in the intensive layout in the place, 8 Support Positions of inner canister and outer tank support and connection.
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 is all channel-section steel, angle steel or T bar.
The utility model has the advantages that:
The utility model is to adopt 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 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, make tank body resisting to lose stability under external pressure ability strong, tank body circularity is easily controlled, 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 utility model, have further strengthened stiffening effect.

Fig. 2 is the cut-away section structural representation of low-temperature (low temperature) vessel inner canister stiffening device provided by the utility model;
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 utility model 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 has been arranged on the sparse stiffening ring 5 at tank interior end socket 3 positions, also comprises being arranged on the support reinforcing circle 5 that tank interior is used for supporting support place 4 of outer tank.The utility model 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.
