Abstract
The utility model relates to a vacuum powder insulation presss from both sides cover shell body passageway of managing to find time, including inner container and shell body, be equipped with the powder supporting layer between inner container and shell body, still including setting up a set of reinforcing ring between powder supporting layer and shell body section of thick bamboo wall, form the annular passageway of managing to find time between reinforcing ring and the outer shells inner wall. For the adiabatic effect that improves the cryo equipment, reduce the resistance of evacuation, take to utilize cross -section that the interior reinforcing ring that presss from both sides the cover shell constitutes for the hoop passageway of circle body and increase the structure of axial water conservancy diversion, increased the evacuation aisle spare greatly, make jar whole evacuation of body intermediate layer more even, showing the time of having reduced double -layered set of evacuation, it is more even, tightly in fact to make in the intermediate layer vacuum powder load simultaneously. Not only shorten manufacturing cycle, improved product life simultaneously.
Description
Technical field
This utility model relates to a kind of vacuum-powders insulation chuck shell body evacuation passage, a kind of low temperature insulation container evacuates structure, suitable in the low-temperature (low temperature) vessel of vacuum-powders insulation form, it is particularly suited for the interlayer vacuum-pumping structural design of vertical, horizontal and portable medium-sized cryogenic tank container.
Background technology
Cryogenic tank container is that long storage periods liquid must take effective insulation, often it is designed to double-decker, thermal insulating layer is formed, to reduce the heat of importing content device due to conduction, convection current and radiation between inner pressurd vessel (storage cryogenic liquid) and shell body. And the heat insulating construction of interlayer directly affects cryogenic liquid vessel evaporation rate, thus govern the serviceability of cryogenic liquid vessel.
According to the applicant understood, the low-temperature storage tank of traditional vacuum powder isolation, adopts an evacuation tube to extract the air in chuck, when vacuum reaches more than 0.06MPa, start to be filled with vacuum powder in interlayer, utilize the negative pressure in interlayer to make vacuum powder flow to mezzanine space; On the other hand, by being filled with elevated pressures nitrogen (0.1-0.2MPa) with compacting vacuum powder, so the continuous filling of interlayer vacuum-pumping circulation, compacting vacuum powder being filled to tank body interlayer. But evacuation tube is positioned at equipment side along length of tank direction so that distance evacuation tube position farther out evacuates that effect is weak, being short of power of vacuum powder flowing, thus there is the vacuum powder skewness of portion, can reduce the effect of heat insulation of interlayer.
Utility model content
The purpose of this utility model is in that: for above-mentioned prior art Problems existing, it is proposed to the vacuum-powders insulation chuck shell body evacuation passage of a kind of low-temperature (low temperature) vessel suitable in vacuum-powders insulation form.
In order to reach object above, a kind of vacuum-powders insulation chuck shell body evacuation passage of the present utility model, including inner pressurd vessel and shell body; It is characterized in that: between inner pressurd vessel and shell body, be provided with powder supporting layer; Also include the one group of stiffening ring being arranged between powder supporting layer and shell body barrel; Annular evacuation passage is formed between described stiffening ring and shell body inwall.
The technical scheme that this utility model limits further as:
Further, between described powder supporting layer and stiffening ring, it is provided with powder sealing coat.
Further, described shell body inwall is additionally provided with reflecting layer.
Further, the superpressure safeguard and the powder that also include being arranged between shell body and supporting layer add ingress interface.
Further, between shell body and evacuation passage, it is provided with vacuum gauge and evacuates mouth.
Further, connected by conduit between described stiffening ring.
The beneficial effects of the utility model: for improving the insulation effect of cryogenic equipment, reduce the resistance of evacuation, take hoop passage that the cross section that the inner stiffener ring utilizing chuck shell forms is circle body and increase the structure of axial diversion, greatly increase evacuation passageway area, tank body interlayer entirety evacuation is made to be more uniformly distributed, significantly reduce the time of chuck evacuation, make in interlayer vacuum powder filling be more uniformly distributed, consolidation simultaneously. Not only shorten the manufacturing cycle, improve product service life simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is the structural representation of one embodiment of this utility model.
Detailed description of the invention
Embodiment one
A kind of vacuum-powders insulation chuck shell body evacuation passage of the present embodiment, basic structure as it is shown in figure 1, include reflecting layer 1, inner pressurd vessel 2, perlite powder supporting layer 3, safeguard/perlite adds entrance 4, outer container stiffening ring 5, powder sealing coat 6, shell body 7, perlite powder 8, safeguard/perlite adds entrance 9, vacuum gauge/evacuation mouth 10.
Increase reflecting layer 1 at shell body 7 inner surface, for stoping the hyperthermia radiation heat in the external world to enter inner canister through shell body, improve the effect of heat insulation of chuck.
Perlite powder supporting layer 3 coordinates outer container stiffening ring 5, forms ring section as evacuation passage between outer container and inner pressurd vessel, and arranges interface channel between annular stiffening ring 5, increases evacuation passage area. To increase the aisle spare of evacuation, improve evacuation efficiency.
Powder sealing coat 6, is made up of silk screen, alkali-free cloth and press strip, stops pearlite thermal insulation powder 8 to enter evacuation passage. And set up safeguard on described shell body 7, in case inner canister leakage causes the entrance of the blast of shell body hypertonia and perlite powder.
By the structure of the present embodiment, the part-structure that can directly utilize apparatus body increases the evacuation passage area of chuck, is integrally improved interlayer vacuum-pumping efficiency, makes vacuum powder filling more uniform, shortens the device fabrication cycle simultaneously. Suitable in the low-temperature (low temperature) vessel of vacuum-powders insulation form, it is particularly suited for the interlayer vacuum-pumping structural design of medium-sized cryogenic tank container.
In addition to the implementation, this utility model can also have other embodiments. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within the protection domain of this utility model requirement.
