Intensity.Use occasion according to adiabatic quilt is different, can be divided into: end socket adiabatic by 1, cylinder adiabatic by 2 with folder
Layer pipe insulation quilt.
For end socket adiabatic by 1 prefabricated, according to end socket adiabatic by 1 profile, first according to the end socket portion of inner pressurd vessel 4
External surface area calculate end socket adiabatic by 1 diameter, then, add end socket adiabatic adiabatic with cylinder by 2 by 1
Overlap, the thermal insulation of required end socket can be determined by the overall dimensions of 1.
In view of when carrying out the wrapping of adiabatic quilt, the end socket portion of described inner pressurd vessel 4 has the interlayer pipeline stretched out,
To this end, two semicircle adiabatic quilts can be prefabricated into adiabatic for end socket by 1, it is as shown in Figure 3, Figure 4 upper respectively

Wrapping work time, can according to the interlayer pipeline stretched out come to semicircular upper semi-circle adiabatic by 101, lower half circle exhausted
Heat is carried out corresponding cutting by 102.
In end socket thermal insulation by the prefabrication process of 1, insulating unit 10 can be cut into semicircle according to design size,
It is 1 heat-insulating block 9 with semicircle insulating unit 10 according to every 20 layers of radiation shield again, when i.e. radiation shield is 40 layers, altogether
Having 2 heat-insulating blocks 9, rule is combined into upper semi-circle heat-insulating block, lower half circle heat-insulating block according to this.Adiabatic at described upper semi-circle
Block, lower half circle heat-insulating block close cylindrical side circumferencial direction on connect the second frenulum 6 and circumference so that sewing mode is fixing
Accepting band 7, described second frenulum 6 arranges several, and is distributed ringwise in equidistant mode, adiabatic at upper semi-circle
Fix the first frenulum 5 of the some equidistant arrangements of connection on the straight flange end of block in sewing mode after, formed as shown in Figure 4

One frenulum 5 is banding glass fibre belt, and the second described frenulum the 6, the 3rd frenulum 12 is ring-type glass fibre belt, described circumference
Accepting band 7 is circumferential band glass fibre belt；Further, when sewing the second frenulum 6, circumference undertaking band 7, second it is
Accept with 7 overlapped bearings with circumference with 6, should carry out intersecting sewing, i.e. connect bearing first corresponding
Sew square box, then in square box, sew X-shaped, as in figure 2 it is shown, to ensure sewing intensity；Described circumference
Accept also should sew on the circumferencial direction of its place heat-insulating block 9 bearing with 7, with prevent the second frenulum 6,
Circumference is accepted band 7 and is pulled de-in wrapping process.By coordinating of the first frenulum 5 and the 3rd frenulum 12, Ke Yifang
Just upper semi-circle thermal insulation is adiabatic with lower half circle by 102 interconnections by 101, and the end socket of formation circle as shown in Figure 3 is exhausted
Heat is by 1, for wrapping up the end socket part of vacuum insulation deep cooling pressure vessel.
For cylinder adiabatic by 2 prefabricated, first cylinder external diameter and the adiabatic design by 2 of cylinder according to inner pressurd vessel 4 are thick
Degree, calculates that cylinder is adiabatic is wound around the length required for inner pressurd vessel 4 one weeks by 2, thus, cylinder adiabatic by 2 week
Just determined to length, then, according to the barrel lenght of inner pressurd vessel 4, calculated required cylinder adiabatic by 2
Width quantity.
Shell portion in view of inner pressurd vessel 4 is long, if the cylinder of processing monoblock is adiabatic by 2 cladding inner pressurd vessels 4
Shell portion, not only because being limited by radiation shield and interval insulant fabric width and difficulty of processing is big, and processing cost is high.
In order to improve the prefabricated efficiency that cylinder thermal insulation is by 2, save the processing cost that cylinder thermal insulation is by 2, can be adiabatic by cylinder
It is designed to be by 2 and is spliced by unit 8 by some prefabricated cylinder thermal insulation.Described cylinder is adiabatic by unit 8 such as
Shown in Fig. 6, cylinder adiabatic by unit 8 length direction on accept band 3 with the fixing circumference that connects of sewing mode, and
Cylinder is adiabatic is connected the first frenulum 5 and the second frenulum so that sewing mode is fixing respectively by the both sides on unit 8 width
6.Adjacent cylinder is adiabatic is formed by connecting cylinder thermal insulation by 2 by unit 8 by first frenulum the 5, second frenulum 6.?
Concrete calculate needed for cylinder adiabatic quantity by unit 8 time, it shall be guaranteed that cylinder is adiabatic by excellent on the width of 2
First use formed cylinder body adiabatic by the width of unit 8, it is impossible to when rounding, last block cylinder thermal insulation is entered by unit 8
The corresponding cutting of row.
Being calculated by above, adiabatic length, width dimensions and the cylinder by 2 of cylinder is adiabatic by the requisite number of unit 8
Amount is determined, next only need to by the size of design carry out cylinder adiabatic by 2 prefabricated.
Carry out cylinder adiabatic by 2 prefabricated time, insulating unit 10 can be cut into rectangle according to design size, so
After the insulating unit 10 after cutting misplaced on length and width direction be respectively compounded to form staggered floor knot after 90-110mm
The heat-insulating block 9 of structure, i.e. 4 insulating units 10 are respectively arranged with 3 staggered floors, as shown in Figure 7 on length and width direction.
When prefabricated, can every 10 layers of radiation shield be 1 heat-insulating block 9, when i.e. radiation shield is 40 layers, have 4 thermal insulation
Block 9.After using the design of such structure, when carrying out wrapping up operation, the staggered floor at two ends will mutually in the longitudinal direction
Overlap joint, such that it is able to the heat-insulating block 9 caused due to wrapping error when being effectively prevented wrapping causes because not closing
" airbreak ", or intersection too much cause cylinder adiabatic by 2 local thickness and the number of plies problem such as too much；Meanwhile,
By adjacent heat-insulating block 9 mutual staggered floor overlap joint, thus heat-insulating block 9 can also be connected as in an orderly manner in the direction of the width
One entirety.Note: heat-insulating block 9 described herein is exhausted according to the cylinder formed as shown in Figure 6 after design size cutting
Heat is by unit 8.
After the insulating unit 10 for cylinder is combined into heat-insulating block 9, need on the length direction of heat-insulating block 9 with seam
The fixing circumference that connects of mode processed accepts band 3, and the both sides on heat-insulating block 9 width are fixed in sewing mode respectively
Connect the first frenulum 5 and the second frenulum 6, as shown in Figure 6.Wherein, first described frenulum the 5, second frenulum 6
It is respectively provided with some, and is distributed in equidistant mode；Described circumference accepts band 3 employing glass fibre belt, arranges some altogether
Bar, and arranged in parallel in equidistant mode, connection the is fixed in sewing mode in the one end accepted with 3 each article of circumference
One frenulum 5, the other end also connects the second frenulum 6 so that sewing mode is fixing；Band 3 and the first frenulum 5 is accepted in circumference
Between connect bearing, accept with 3 and second connection bearings between frenulum 6 in circumference, should hand over respectively
Fork sewing, with ensure sewing intensity, prevent wrap up operation time pull de-.When wrapping, it is only necessary to by the first frenulum
In 5 hollow ring putting in the second frenulum 6, and stretch into the length of the second frenulum 6 hollow ring by adjusting the first frenulum 5
Control the wrapping elasticity that cylinder thermal insulation is by 2, after cylinder thermal insulation is adjusted by the wrapping elasticity of 2, by first
Frenulum 5 and the second frenulum 6 mutually tie a knot tie-down just can, as shown in Figure 2.
When insulating unit 10 is carried out cutting according to design size, according to the difference of use occasion, can press from both sides being used for
The insulating unit 10 of layer pipeline is cut into rectangle, is then combined with each other according to the design number of plies by insulating unit 10, and
It is combined into web-like, forms interlayer pipeline insulation block, be used for wrapping up interlayer pipeline portions.On described interlayer pipeline insulation block
Need not sew the glass fibre belt for connecting, direct on-demand cutting wrapping up during wrapping.
2nd step, the wrapping of adiabatic quilt.The wrapping of thermal insulation quilt described here, refers to prefabricated end socket thermal insulation quilt
1, cylinder is adiabatic is wound around wrapping at the inner pressurd vessel 4 of vacuum insulation deep cooling pressure vessel and the outer surface of interlayer pipeline by 2,
Then, by adjusting and fastening first frenulum the 5, second frenulum 6 of correspondence, the 3rd frenulum 12 etc., end socket is adiabatic
By 1, cylinder thermal insulation is fixed on inner pressurd vessel 4 and interlayer pipeline by 2.When concrete wrapping operation, first complete cylinder
Adiabatic by 2 wrapping, then complete end socket adiabatic by 1 wrapping.Specifically:
It is to be spliced by unit 8 by a number of cylinder thermal insulation owing to cylinder is adiabatic by 2, therefore, is carrying out cylinder
Body adiabatic by 2 wrapping operation time,
First, will be located in cylinder thermal insulation to be adjusted by first frenulum the 5, second frenulum 6 on unit 8 length direction
And fasten；
Then, cylinder adiabatic by unit 8 width by adiabatic for adjacent two pieces of cylinders by unit 8 by being positioned at cylinder
Body thermal insulation is adjusted by the first frenulum 5 on unit 8 or the second mutual correspondence of frenulum 6 and fastens, and by wrapping
Order wraps up the other end successively from inner pressurd vessel 4 one end, it is ensured that cylinder is adiabatic will not be occurred position from each other by unit 8
Move.
When wrapping, two pieces of adjacent cylinder thermal insulation should be staggered mutually by the seam on unit 8 length direction, so may be used
So that after cylinder thermal insulation has been wrapped up by 2, thickness uniformity, outward appearance are regular everywhere, and the beneficially later stage is carried out very
The suit of the inside and outside container of empty adiabatic deep cooling pressure vessel and the heating evacuation work of interlayer.
After cylinder thermal insulation has been wrapped up by 2, the wrapping that end socket thermal insulation is by 1 can be carried out, specifically:
Carry out end socket adiabatic by 1 wrapping operation time,
First, by adiabatic for upper semi-circle by 101, lower half circle thermal insulation be wrapped in end socket portion by 102 outer surface on, and make
Adiabatic with cylinder by 2 overlap joints to determine relative position.
Then, according to stretching out the position of interlayer pipeline on end socket, end socket thermal insulation is carried out cutting by 1, by interlayer pipeline from
End socket thermal insulation passes on 1.End socket thermal insulation is divided into upper semi-circle by 1 adiabatic adiabatic by 102 liang by 101 and lower half circle
Part, is so conducive to the wrapping of interlayer pipeline, and when wrapping, it is also possible to by interlayer pipeline stretching on end socket
End socket thermal insulation is carried out cutting by 1 by out position, in order to interlayer pipeline is adiabatic by 1 through end socket.
It follows that the cylinder that will be close to end socket side is adiabatic, to be pressed in end socket by unit 8 adiabatic by below 1, and will be located in cylinder
Body adiabatic by the first frenulum 5 on unit 8 with to be positioned at end socket adiabatic by the corresponding connection of the second frenulum 6 on 1, pass through
Adjust and fasten first frenulum the 5, second frenulum 6, just can complete cylinder adiabatic adiabatic by the company between 1 by 2 and end socket
Connect.Be ring-type glass fibre belt owing to end socket is adiabatic by the second frenulum 6 on 1, therefore, close inner pressurd vessel 4 two ends end socket
The first frenulum 5 that the cylinder thermal insulation in portion is sewed in width both sides by unit 8 is banding glass fibre belt, to facilitate envelope
Head is adiabatic by the overlap joint between unit 8 and is adjusted elasticity by 1 and cylinder thermal insulation, improves the wrapping efficiency of adiabatic quilt.
In order to improve wrapping work efficiency further, it is ensured that wrapping quality, can by adiabatic for upper semi-circle by 101, lower half circle exhausted
Heat is arranged to by the sewing spacing of the second frenulum 6 on 102
Sewing spacing with 5 is corresponding.
Finally, until upper semi-circle adiabatic by 101, lower half circle is adiabatic bandaged by 2 with cylinder thermal insulation respectively by 102 after,
By adiabatic for upper semi-circle by 101, the adiabatic straight flange end by 102 of lower half circle mutual by the first frenulum the 5, the 3rd frenulum 12
Overlap joint, and the first frenulum the 5, the 3rd frenulum 12 is adjusted and fastens.So far, vacuum insulation deep cooling pressure vessel
Heat insulating construction be fully completed.
When carrying out wrapping up operation, typically require end socket adiabatic by 1, cylinder adiabatic by 2 " pine and do not collapse ", if envelope
Head adiabatic by 1, cylinder adiabatic by 2 wrapping tensions, it will when causing evacuating, the absorption gas on adiabator surface is very
Difficult effusion, causes evacuated time length and the undesirable consequence of insulation effect.If end socket adiabatic by 1, cylinder adiabatic by 2
Wrapped up pine, it will cause " airbreak " of container local and coming off of adiabator, thus affect insulation effect.One
As, end socket adiabatic by 1, the adiabatic layer density domination by 2 wrappings of cylinder be advisable at 23-28 layer/cm.
In view of inner pressurd vessel 4 generally GB150-1998, in order to avoid inner pressurd vessel 4 outer surface and end socket adiabatic by 1,
Cylinder is adiabatic to be close on 2 between the radiation shield of inner pressurd vessel 4 outer surface, because of direct contact, heat " short-circuit " occurs, permissible
End socket adiabatic by 1, cylinder adiabatic by 2 on the radiation shield being close to inner pressurd vessel 4 outer surface outside compound 3-5 interlayer
Barrier material is to form adiabatic sealing coat 11, as shown in Figure 8.End socket adiabatic by 1, cylinder adiabatic by 2 on be close to
Before the radiation shield of inner pressurd vessel 4 outer surface is compound with interval insulant, should first punch, i.e. at this radiation shield length and width
Stamp the hole of Φ 6mm-Φ 8mm on degree direction at interval of 100mm-500mm, during to facilitate evacuation, absorption is at adiabator
The gas on surface can escape from this aperture.
After the prefabricated wrapping of inner pressurd vessel 4 body completes, in addition it is also necessary to the Sandwich pipeline to vacuum insulation deep cooling pressure vessel
Sandwich pipeline thermal insulation is used to be wrapped up.Described Sandwich pipeline thermal insulation quilt prefabricated, wrapping substantially with above-mentioned end socket
Adiabatic by 1, cylinder adiabatic by 2 prefabricated, wrapping method is identical, its difference is that Sandwich pipeline thermal insulation is not had above
There is the glass fibre belt sewed for wrapping.When carrying out the prefabricated wrapping of Sandwich pipeline, it is from interlayer pipe according to pipeline specifications
The adiabatic adiabator certain by upper cutting in road is also wound around wrapping at Sandwich pipeline outer surface, then, uses the band separated
Shape glass fibre belt is wound around by outer surface in thermal insulation and tightens fixing.
When cylinder adiabatic by 2, end socket is adiabatic all wrapped up by 1 and Sandwich pipeline thermal insulation after, carry out outside entirety
Seeing and check, should ensure that adiabatic wrapping should be solid and reliable everywhere by without slack and undisciplined phenomenon, outward appearance is neat, without ledge.
Use this utility model, the prefabricated of corresponding adiabatic quilt, when prefabricated, adiabatic quilt can be carried out by design requirement
Compound, cutting and sewing can complete by means of special purpose machinery, by by means of mechanized operation, and can be significantly
Reduce labor workload, and farthest avoid the damage of the adiabator manually caused at manual compound tense
And pollution；It addition, also be there is neat appearance, thickness damage uniform, mechanical by the thermal insulation that machinery scale is prefabricated
Wound less and pollutes the plurality of advantages such as little.And, corresponding adiabatic by when prefabricated, can determine specially according to single container
System, when carrying out corresponding thermal insulation by size design, can preferentially select regular size according to the overall dimensions of container
Adiabator, it is impossible to when rounding, only need to be carried out cutting by last block thermal insulation by design size, be improve absolutely
The making of hot material and wrapping efficiency, reduce adiabator and risk damaged, that pollute occur.When wrapping, only need
Corresponding thermal insulation is wrapped in successively inner pressurd vessel and the outer surface of interlayer pipeline, and by fastening corresponding glass fibre belt,
Just can simply and efficiently complete the wrapping of adiabatic quilt, have simple to operate, wrapping efficiency is high, the wrapping used time is few
