Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1 and fig. 2. It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, changes of the ratio relationship, or adjustment of the sizes should still fall within the scope covered by the technical contents disclosed in the present invention without affecting the efficacy and the achievable purpose of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a vacuum container, which comprises an inner shell 2, an outer shell 1, and a radiation-reflecting layer 3 made of radiation-reflecting material and disposed between the outer shell 2 and the inner shell 1, wherein a spacing layer formed by winding a spacing bar 4 is further disposed between the outer shell 1 and the inner shell 2, a vacuum interlayer 100 is disposed between the inner shell and the outer shell, and a storage cavity 200 for storing a substance is disposed in the inner shell; the spacing strip 4 comprises a silk screen 41 and an adsorbing material 42, wherein the silk screen 41 is a sleeve-shaped structure formed by weaving silk pieces, and the adsorbing material 42 is filled in the silk screen. The utility model provides a spacer 4 for having adsorbing material 42, consequently this spacer 4 has the adsorption efficiency, need not to set up adsorbing material alone in addition again, promotes vacuum vessel's performance level.
The middle interlayer in the embodiment is positioned in the anti-radiation layer 3, or positioned between the inner shell 2 and the anti-radiation layer 3, and can be directly wound on the inner shell 2. Spacer layers may also be provided both in the radiation-reflecting layer 3 and between the inner envelope 2 and said radiation-reflecting layer 3.
The spacing bars 4 in the embodiment are spirally wound, and the anti-radiation layers are partially supported on the radial section of the vacuum container, so that the consumable materials of the spacing bars 4 are saved. In the embodiment, the spacing bars are spirally wound at equal intervals, and the winding intercept can be 1cm-10 m.
In this embodiment, the filament-like member is made of a material with low thermal conductivity and low outgassing rate, such as fiberglass filament and asbestos.
