Abstract
The invention belongs to the field of processing for the vacuum interlayer of an insulated container, in particular to an adsorption device for the vacuum interlayer of a lower-temperature container. The adsorption device comprises a fixing plate I, two fixing plates II and an adsorbent, wherein each of the fixing plate I and the two fixing plates II is in an n-shaped structure and comprises a transverse plate and two vertical plates; the middles of the transverse plates of the two fixing plates II are vertically connected with the two ends of the transverse plate of the fixing plate I respectively; the two vertical plates of the fixing plate I are respectively connected with the inner wall of the vacuum interlayer; the adsorbent is positioned in the space formed by the fixing plate I, the two fixing plates II and the inner wall of the vacuum interlayer. The adsorption device has the beneficial effects that the contact area of the adsorbent and the vacuum interlayer is increased, the adsorbent is replaced after the vacuum lifetime of a tank is reached, and the transport security is improved. An adsorbent protecting cover is fixed on the inner wall of the rear seal head of an outer tank of the lower-temperature container in a welding manner to ensure that the adsorbent cannot fall.
Description
Technical field
The invention belongs to thermally insulated container vacuum sandwich process field, particularly relate to a kind of low-temperature (low temperature) vessel vacuum sandwich adsorbent equipment.
Background technique
Outer tank body sleeve structure in vacuum insulation vessel tank structure adopts, the vacuum sandwich formed between the interior outer tank be evacuated has heat insulation with the requirement reaching carrying liquefied gases Security.But after low-temperature (low temperature) vessel interlayer vacuum-pumping, jacket gas concentration sharply reduces, the H in tank body metal
2will vacuum sandwich be discharged into, the degree of vacuum between interior outer tank is declined, thus reduce insulation effect.
Prior art as shown in Figure 1, by after sorbent sheathing paper and woven wire cloth parcel, hang on one of Stainless Steel Wire, then by the other end spot welding of Stainless Steel Wire on outer tank rear head, in this technology, sorbent is wrapped in together, and the surface of contact of sorbent and vacuum sandwich is the outer surface of this parcel, and the sorbent at parcel center can not contact with vacuum sandwich, can not give full play to the adsorption function of sorbent, adsorption efficiency is low.And in this technology, the connection of adsorbent units and outer tank end socket is unreliable, in transportation process, is subject to vibration easily drops, be unfavorable for changing sorbent after tank body vacuum life arrives.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low-temperature (low temperature) vessel vacuum sandwich adsorbent equipment, increases the area of contact of sorbent and vacuum sandwich, is convenient to change sorbent after tank body vacuum life arrives, and improves Transport Safety.
The present invention for solving the problems of the technologies described above adopted technological scheme is:
There is provided a kind of low-temperature (low temperature) vessel vacuum sandwich adsorbent equipment, its special way is: comprise one piece of fixed plate one, two pieces of fixed plates two, sorbents; One piece of fixed plate one and two pieces of fixed plates two are " door " shape structure, and namely three includes one piece of transverse slat and two pieces of risers, is connected respectively in the middle part of the transverse slat of two pieces of fixed plates two with the transverse slat two ends of fixed plate one are vertical; Two pieces of risers of fixed plate one are connected with vacuum sandwich inwall respectively; Sorbent is positioned at the space that one piece of fixed plate, one, two pieces of fixed plates two and vacuum sandwich inwall are formed.
The hardness of fixed plate one and fixed plate two is 65.7 ~ 78.7 (HRB), and elongation after fracture is 22% ~ 30%.
Sorbent outer wrap has sheathing paper and woven wire cloth.
The invention has the beneficial effects as follows: the area of contact increasing sorbent and vacuum sandwich, be convenient to change sorbent after tank body vacuum life arrives, improve Transport Safety.Sorbent safety cover is fixed by welding on low temperature container external pot rear head inwall, ensures that sorbent can not drop.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Fig. 2 ~ Fig. 6, the present invention includes one piece of fixed plate one 7, two pieces of fixed plates 26, sorbents; One piece of fixed plate one and two pieces of fixed plates two are " door " shape structure, and namely three includes one piece of transverse slat and two pieces of risers, fix respectively in the middle part of the transverse slat of two pieces of fixed plates two with the transverse slat two ends vertical welding of fixed plate one; Two pieces of risers of fixed plate one are welded and fixed with vacuum sandwich inwall respectively; Sorbent is positioned at the space that one piece of fixed plate, one, two pieces of fixed plates two and vacuum sandwich inwall are formed.Fixed plate one adopts the sheet material of 2mm thickness to manufacture, the sheet material that fixed plate two adopts 0.5mm thick is manufactured, the hardness of fixed plate one and fixed plate two is 70 (HRB), elongation after fracture is 26%, fixed plate two does not weld with outer tank rear head, and the fan-shaped one end of fixed plate two can be opened flexibly with hand.After sorbent safety cover and end socket assembly welding complete, after sorbent woven wire cloth and sheathing paper being wrapped, put into sorbent safety cover by the fan-shaped one end of fixed plate two, and fan-shaped for fixed plate two one end is folded, ensure that sorbent parcel does not drop.Sorbent is divided into several parcel packagings of formed objects, to increase the area of contact of sorbent.
