Abstract
The invention relates to an interlayer adsorbent box of a thermal insulating container. The interlayer adsorbent box comprises an adsorbent filling shell, wherein an opening device and an air guide pipe are arrange at the bottom of the adsorbent filling shell; a sealing device is connected to the lower end of the air guide pipe. The interlayer adsorbent box is kept sealed before a vacuum interlayer is put in, is opened after the vacuum interlayer is put in and begins to work again after reaching a work position; the effect of the adsorbent can be exerted to the greatest extent; the vacuum life of a cryogenic thermal insulation container is prolonged to the greatest extent; the adsorption efficiency is high; the cost is low and the stability is high.
Description
Technical field
The present invention relates to deep cooling vacuum-powders insulation vessel fabrication technical field, be specifically related to a kind of adsorbent box for heat insulation container interlayer.
Background technique
Deep cooling vacuum insulation vessel content device and outer container, inner container carries-196 DEG C of cryogenic liquids, forms Sealed sandwich between inner container and shell, and being evacuated to this interlayer is the key reaching insulation effect.But the sealing of this interlayer is not absolute, As time goes on, the gas of vacuum of bleeding gets more and more, and degree of vacuum is also just more and more lower, and insulation effect also just worse and worse.When low vacuum is to prescribed minimum, the vacuum life of meaning terminates.For asking longer vacuum life, wishing after sealed vacuum interlayer is formed, adopting the gas that adsorbent bleeds.Sorbent so should do not allowed before entering interlayer to start adsorbed gas, after it namely should be allowed to enter interlayer, start absorption.This just needs design sorbent box, and sorbent is box-packed to be entered should keep sealing before vacuum sandwich, load vacuum sandwich will open.Although prior art also devises sorbent box, but fail to solve to load and to keep sealing before vacuum sandwich, load the problem that vacuum sandwich opens, but just sorbent box is opened before loading vacuum sandwich, cause sorbent not to the moisture that the opportunity of this adsorbed gas has just adsorbed gas in advance and adsorbed in air, make sorbent lose major part effectively adsorptive power.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes a kind of adsorbent box for heat insulation container interlayer, this sorbent box absorption efficiency is high, cost is low, stability is strong.
Technological scheme of the present invention is: a kind of adsorbent box for heat insulation container interlayer, and comprise sorbent and fill shell, the bottom of filling shell at described sorbent is provided with an opening device and an air pipe, is connected with sealing device in the lower end of air pipe.
Shell filled by described sorbent is cuboid.
Shell filled by described sorbent is square body.
Shell filled by described sorbent is spheroid.
Described sorbent is filled shell and is made up of aluminum alloy material.
Described sorbent is filled shell and is made up of stainless steel material.
The present invention has the following advantages:
1) absorption efficiency of the present invention is high, stability is strong;
2) present device deadweight is little, cost is low;
3) the present invention can play the usefulness of sorbent to greatest extent, extends the vacuum life of deep cooling vacuum insulation vessel to greatest extent.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is cross-sectional view of the present invention.
In figure, 1. shell filled by sorbent; 2. air pipe; 3. support device; 4. inner container; 5. vacuum sandwich; 6. outer container; 7. opening device; 8. sealing device.
Embodiment
Further illustrate below in conjunction with accompanying drawing, and unrestricted scope involved in the present invention.
Shown in Figure 1, the present invention includes sorbent and fill the compositions such as shell 1, sealing device 8, air pipe 2, opening device 7, its working principle is:
In deep cooling vacuum-powders insulation container working process, before inner container 4 and outer container 6 are set with, the sorbent activated are filled to sorbent and fill shell 1, and sealing device 8, opening device 7 are sealed appropriate, after deep cooling vacuum vessel suit, interlayer vacuum-pumping, forms vacuum sandwich 5.Now, open sealing device 8, be filled with high purity inert gas, enter after sorbent filling shell 1 through air pipe 2, opening device 7 is opened, then stop being filled with high purity inert gas, and by appropriate for sealing device 8 sealing, prevent outside atmosphere from entering vacuum sandwich 5.Now sorbent is communicated with vacuum sandwich 5, and sorbent is started working.The shape that shell 1 filled by described sorbent can be cuboid, and also can be square body, also can be spheroid.Sorbent is filled shell 1 and can be made up of stainless steel material, now can weld sorbent and fill shell 1, make it to link together with the outer casing bottom of inner container 4, sorbent is filled shell 1 and is made up of aluminum alloy material, now can fill shell 1 at sorbent and weld together with the outer casing bottom of inner container 4.
In the present invention, the movement of deep cooling vacuum vessel, higher than the bottom of support device 3, is convenient to like this in the bottom of sealing device 8.
The present invention is succinct, efficient, practical, is a kind of cost adsorbent box for heat insulation container interlayer low, easy to use.
