Description
Technical field
It the utility model is related to a kind of low-temperature (low temperature) vessel back support structure.Suitable for big volume low-temperature (low temperature) vessel.
Background technology
Vacuum and low temperature container is to be used to store and conveying liquified weather（LNG）, liquid oxygen, the gas cylinder of the cryogenic liquid such as liquid nitrogen,
It can be especially useful for the supply of the supply of automobile LNG fuel, residential area and the bottled fuel of industrial LNG, and electronics, section
Grind, the supply of chemical industry, the industry such as welding and the bottled fuel of industrial LNG.Generally, known low-temperature (low temperature) vessel is equipped with including liner
With the double-decker of outer courage, and vacuumized between liner and outer courage, pass through supporting structure between liner and the interior outside head of outer courage
Connection.Since the supporting structure will bear certain external force during transport and use, it requires that supporting structure has one
Fixed intensity；Further, since what is loaded in liner makes cryogenic liquid, to reduce evaporation loss caused by heat transfer, branch is also required
Support structure must possess small performance of conducting heat.
Chinese patent CN1963283A discloses a kind of inner container supporting structure of low-temperature (low temperature) vessel, is connected using extension interpolation type
Inside and outside end socket is connect, reduces heat transfer.But this structural support structure partial stress concentration, support reliability have much room for improvement.
Particularly with vehicle-mounted big volume low-temperature (low temperature) vessel, intensity cannot ensure.
Utility model content
The purpose of this utility model is to provide a kind of hot small, storing of leakage and stablizes, supports reliable low-temperature (low temperature) vessel back support
Structure.
The technical scheme in the invention for solving the above technical problem is：A kind of low-temperature (low temperature) vessel back support structure, should
Supporting structure includes outer barrel, interior rear head, outer rear head, support plate, small pipe cap, stiffening plate, the vehicle-mounted rear support lantern ring, vehicle-mounted
Rear supporting tube and reinforcing plate；
The interior rear head, small pipe cap, stiffening plate, vehicle-mounted rear supporting tube group postwelding form interior rear head component；The car
Carry rear supporting tube and small pipe cap（5）Group postwelding again with interior rear head, welding with reinforcement plate；The support plate, the vehicle-mounted rear support lantern ring,
Outer rear head, reinforcing plate group postwelding form outer rear head component；The support plate is using circular petal type structure；Petal is raised
Welded with outer rear head inner wall position.
The support plate is six flap-type, eight flap-type, ten flap-type or 12 flap-type.
Circumferencial direction is uniformly provided with delthyrium in the support plate card.
The delthyrium is six, eight, be or 12.
The position of the delthyrium is corresponding with the support plate petal depressed area.
Compared with prior art, the utility model has the advantage of：
Vehicle-mounted rear supporting tube uses pipe fitting, reduces cross-sectional area, effectively reduces heat conduction, and rear envelope in insertion
Head welding, under the action of stiffening plate, also enhances the radial support rigidity of vehicle-mounted rear supporting tube, small pipe cap can play support tube
To the effect of certain reinforcement, while the operating pressure in gas cylinder can be born.
Support plate has certain area, adds thermally conductive pathways, heat conduction is effectively reduced, in the effect of reinforcing plate
Under, also enhance the radial support rigidity of the vehicle-mounted rear support lantern ring.
For support plate using circular petal type structure, cylindrical Position Design is evenly distributed with and the pad of rear head welding, makes its weldering
It is reliable to connect rear uniform force；Remove position at the same time（Depressed area）It can not be contacted with end socket, can effectively reduce the face of heat transfer
Product.Support plate surrounding opens up delthyrium, substantially reduces the cross-sectional area of support plate, so as to reduce Lou heat, effectively reduces
Evaporation rate.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figs. 1-2, the low-temperature (low temperature) vessel back support structure in the present embodiment, the supporting structure by outer barrel 1, it is interior after
End socket 2, outer rear head 3, support plate 4, small pipe cap 5, stiffening plate 6, the vehicle-mounted rear support lantern ring 7, vehicle-mounted rear supporting tube 8 and reinforcing plate
9 compositions.
8 groups of interior rear head 2, small pipe cap 5, stiffening plate 6, vehicle-mounted rear supporting tube postweldings form interior rear head component.After vehicle-mounted
Support tube 8 is welded with interior rear head 2, stiffening plate 6 again with small 5 groups of postweldings of pipe cap, and vehicle-mounted rear supporting tube uses pipe fitting, reduces horizontal stroke
Sectional area, effectively reduces heat conduction, and rear head welding in insertion, under the action of stiffening plate 6, also enhances vehicle-mounted
The radial support rigidity of rear supporting tube, small pipe cap can play the role of support tube certain reinforcement, while can bear gas cylinder
Interior operating pressure.
9 groups of support plate 4, the vehicle-mounted rear support lantern ring 7, outer rear head 3, reinforcing plate postweldings form outer rear head component.Support
Disk has certain length, adds thermally conductive pathways, effectively reduces heat conduction, under the action of reinforcing plate 9, also enhances car
Carry the radial support rigidity of the rear support lantern ring.
Using circular petal type structure, cylindrical Position Design is evenly distributed with position at eight and is welded with rear head support plate, makes its weldering
It is reliable to connect rear uniform force；Removing position at the same time can not contact with end socket, can effectively reduce the area of heat transfer.Support plate four
Eight delthyriums of Zhou Kaishe, substantially reduce the cross-sectional area of support plate, so as to reduce Lou heat, effectively reduce evaporation rate.
In addition to the implementation, the utility model has further included other embodiment, all to use equivalents or equivalent
The technical solution that substitute mode is formed, should all fall within the protection domain of the utility model claims.
