Description
Technical field
The utility model is related to LNG storage device technical fields, are related specifically to a kind of novel-vertical storage of drawstring that sprains
Tank.
Background technology
LNG (liquefied natural gas, LiquefiedNatural Gas) is a kind of energy of clean and effective, is widely used in
In industrial production and daily life.LNG needs are stored in the environment of low temperature, transported and are supplied, therefore LNG storage device skills
Art becomes one of the key technology of LNG fuel areas.Vertical low temperature storage tank is one kind of LNG storage devices, mainly by inner pressurd vessel,
The components such as shell and its support construction form.Wherein, support construction is particularly critical, and the design of support construction is to device fabrication hardly possible
Easily, equipment stressing conditions quality all plays important function.Currently, the storage tank supporting structure on domestic market is different, it is different
Support construction has the different scope of application.Although the side wall support mechanism material cost suitable for minitype vertical type storage tank is relatively low,
Manufacturing cost is bigger, and thermal coefficient is higher, and assembling is complex, constrains the manufacturing cycle of entire product.
Such as the Chinese invention patent that publication No. is CN107339600A, a kind of vertical low temperature container, including liner are disclosed
And shell, it is equipped with end socket between the liner top outer and cover top portion inside and axially supports, outside the liner at the bottom
Steel pipe glass reinforced plastic support is equipped between on the outside of side and the outer casing bottom.Supporting mechanism in the vertical low temperature container is typical
Steel pipe+glass fibre reinforced plastic structure, manufacturing process is cumbersome, and thermal coefficient is higher, is not suitable for 20 cubic metres and small-sized Low Temperature Liquid below
Body vertical double container.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of novel-drawstring vertical storage tank that sprains, support constructions
Suitable for 20 cubic metres and following small-sized cryogenic liquid vertical double container, manufacturing process is simple, easy to assembly.
Technical solution adopted by the utility model to solve its technical problems is a kind of novel-drawstring vertical storage tank that sprains,
Including inner pressurd vessel and outer container, the two is coaxially vertically arranged, and outer support is equipped in outer container bottom.In addition, inner pressurd vessel and outer appearance
There are interlayer spaces between device, for thermal insulation material, inner support and pipeline to be arranged.In the present invention, inner support is using upper
Lower support structure, to sprain, lower support is drawstring, increases the flexibility of inner pressurd vessel, and reduce heat transfer area for upper support.
As further improvement of the utility model scheme, described sprain reverses 180 ° of steel plate, one end welding for stage casing
On the outside of interior container top, the other end is welded on outer container inside top, and more than one piece is uniformly distributed around inner pressurd vessel.This structure exists
It is welded to connect after inner pressurd vessel suit, the trepanning on outer container can be avoided, reduced manufacturing process, shorten the manufacturing cycle,
Interior outer container angle unmatched problem when suit is also avoided simultaneously.
As further improvement of the utility model scheme, the drawstring is steel casting, and one end is welded on inner pressurd vessel bottom
On portion's end socket, the other end is welded on the steel tank stiffening ring on the inside of outer container, is equally uniformly distributed more than one piece around inner pressurd vessel, is played
The effect of forming a connecting link.In addition, leptosomatic drawstring reduces the heat output of interior outer container, static evaporation rate is reduced, is extended
Basin is held time, while also solving liner in holding low-temperature liquid because shrinkage causes welding position stress is excessive to ask
Topic.
The utility model has the beneficial effects that novel-drawstring the vertical storage tank that sprains described in the utility model, uses
Lower support structure, relative to the other types storage tank on domestic market, structure novel reduces the transmission of cold, reduces system
Process is made, 20 cubic metres and small-sized cryogenic liquid vertical double storage tank below are suitable for.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is novel, it is not used to limit the utility model.
As shown in Figure 1, novel-drawstring the vertical storage tank that sprains described in the utility model, including inner pressurd vessel 2, outer container 4,
Channel steel stiffening ring 3 and outer support 6, outer support 6 are arranged in 4 bottom of outer container, are used to support entire vertical storage tank.Inner pressurd vessel 2 with
The coaxial vertical placement of outer container 4, there are interlayer spaces between the two, for thermal insulation material, inner support and pipeline to be arranged.Inner support
It is divided into upper and lower support construction, to sprain 1, lower support is drawstring 5 for upper support.Spraining, to be welded on the top of inner pressurd vessel 2 outer for 1 one end
Side, the other end are welded on 4 inside top of outer container, and six are uniformly distributed around inner pressurd vessel 2.One end of drawstring 5 is welded on content
On 2 bottom bulkhead of device, the other end is welded on the steel tank stiffening ring 3 of 4 bottom of outer container, is equally uniformly distributed around inner pressurd vessel 2
