Abstract
The utility model discloses a new -type stretching strap support structure, stretching strap including two piece at least symmetrical arrangement, the stretching strap both ends are provided with respectively connects the face, and stretching strap one end is through connecting face and vessel shell fixed connection, and the stretching strap other end is through connecting face and inner container head fixed connection, the utility model discloses a stretching strap preparation is convenient, hold easy welding, the stretching strap is far away from cryogenic liquids's liquid level axial distance, it is long with the radial length of shell to connect the inner container, so heat leakage is very little, the container heat -insulating property is good, and the free amount of deflection of stretching strap is big, the unnecessary structure deteriorate can have been avoided, owing to cancelled the axial distance restriction of vessel shell reinforcing ring with the inner container head, can increase the intermediate layer spatial distance between container top shell and the inner container, further improve the heat -insulating property of container, very be fit for promoting.
Description
Technical field
The utility model is related to low temperature insulation container field, particularly a kind of new-type drawstring supporting structure.
Background technology
At present, vertical low temperature thermally insulated container is designed with double-decker, and inner pressurd vessel is used for storing cryogenic fluids, shell for
Inner pressurd vessel constitutes interlayer, while interlayer is evacuated, to form good adiabatic system.It is different by insulation pattern, can be divided into
High vacuum multiple layer heat insulation pressure vessel and vacuum-powders insulation pressure vessel.The interlayer of high vacuum multiple layer heat insulation pressure vessel is adiabatic
Medium is the aluminium foil and sheathing paper of multilayer, and the interlayer insulating medium of vacuum-powders insulation pressure vessel is pearlife.Large-scale is vertical
Formula low temperature insulation container, its inner pressurd vessel bottom are typically bearing at shell by support tube connection, and inner pressurd vessel top passes through drawstring
Connection is bearing at shell, conventional drawstring supporting structure, and drawstring makes trouble, and welding difficulty, drawstring heat transfer distances are short, leakage heat
Amount is big, and the tension that drawstring bears during inner pressurd vessel cold events is big, easily causes structure destruction.
The content of the invention
The utility model is intended at least to solve to a certain extent one of above-mentioned technical problem in correlation technique.For this purpose,
The utility model proposes a kind of new-type drawstring supporting structure.
The utility model solves the technical scheme adopted by its technical problem：
A kind of new-type drawstring supporting structure, including at least two drawstrings being arranged symmetrically, the drawstring two ends are respectively provided with
There is joint face, drawstring one end is fixedly connected with shell of tank by joint face, the drawstring other end is sealed with inner pressurd vessel by joint face
Head is fixedly connected.
Used as the improvement of above-mentioned technical proposal, the drawstring is flat bar shaped.
Used as the further improvement of above-mentioned technical proposal, one end that the drawstring is fixedly connected with inner pressurd vessel end socket has one
Determine the bending of angle.
Further, the drawstring is arranged around inner pressurd vessel even circumferential.
Further, the joint face is formed using compacting.
The beneficial effects of the utility model are：Drawstring is easy to make, easily welds, and drawstring is from the liquid level axial direction of cryogenic liquid
Distance is remote, and the radical length for connecting inner pressurd vessel and shell is long, so leaking heat very little, container heat-insulating property is good, and drawstring is certainly
It is big by amount of deflection, unnecessary structure destruction can be avoided, due to eliminating the axial direction of shell of tank stiffening ring and inner pressurd vessel end socket
Distance is limited, it is possible to increase the mezzanine space distance between container top shell and inner pressurd vessel, further improves the thermal insulation of container
Energy.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is further illustrated.
Fig. 1 is the front view of old-fashioned drawstring supporting structure；
Fig. 2 is the top view of old-fashioned drawstring supporting structure；
Fig. 3 is the front view of new-type drawstring supporting structure of the present utility model；
Fig. 4 is the top view of new-type drawstring supporting structure of the present utility model.
Specific embodiment
Referring to figs. 1 to Fig. 2, it is old-fashioned drawstring supporting structure, drawstring two ends twist 90, and are respectively welded at shell of tank
On stiffening ring, it is connected with inner pressurd vessel fixture in the middle part of drawstring, the drawstring supporting structure of this form, makes trouble, welding operation
Distance, space are little, and welding difficulty is big, and connection inner pressurd vessel is shorter with the radical length of shell, i.e., heat transfer distances are short, leaking heat
It is many, and due to the position limitation by shell of tank stiffening ring and inner pressurd vessel fixture, liquid level of the drawstring from cryogenic liquid
Axial distance is near, at the same time, mezzanine space also short, the connecing at the top of inner pressurd vessel of distance between container top shell and inner pressurd vessel
Pipe bending section is it is also possible to the depositional plane of insulating medium can be stretched out, these factors can all cause the poor insulation property of container.
With reference to Fig. 3 to Fig. 4, a kind of new-type drawstring supporting structure of the present utility model is arranged symmetrically including at least two
Drawstring 1, in the present embodiment, drawstring quantity is 8, it is preferred that the drawstring 1 is flat bar shaped, and lightweight, loading end width can
The pressure of surface loading is reduced, 1 two ends of drawstring are respectively arranged with joint face 11, and joint face 11 can be formed using compacting, technique letter
Single, 1 one end of drawstring is fixedly connected with 2 stiffening ring of shell of tank by joint face 11,1 other end of drawstring pass through joint face 11 with it is interior
3 end socket of container is fixedly connected, it is preferred that one end that drawstring 1 is fixedly connected with 3 end socket of inner pressurd vessel has the bending of certain angle,
Facilitate the welding of drawstring 1, and be conducive to its stress, band 1 is arranged around 3 even circumferential of inner pressurd vessel.
The utility model changes the installation site of drawstring supporting structure, easy to make with drawstring, easily welds, drawstring
Away from the liquid level axial distance of cryogenic liquid, the radical length for connecting inner pressurd vessel and shell is long, so leaking heat very little, container is exhausted
Good in thermal property, and the free amount of deflection of drawstring is big, can avoid unnecessary structure destruction, due to eliminating shell of tank stiffening ring
Limit with the axial distance of inner pressurd vessel end socket, it is possible to increase the mezzanine space distance between container top shell and inner pressurd vessel, enter one
Step improves the advantage of the heat-insulating property of container, is very suitable for promoting.
Above concrete structure and sized data are that preferred embodiment of the present utility model is illustrated, but this reality
The embodiment is not limited to new creation, those of ordinary skill in the art are in the premise without prejudice to the utility model spirit
A variety of equivalent variations or replacement can be also made down, the deformation or replacement of these equivalents are all contained in the application claim and are limited
In fixed scope.
