specific Embodiment approach 1

[0011] Specific implementation mode 1: Combination Figure 1~2 Explain that the liquid oxygen container with multiple vacuum insulation layers and fiber-reinforced composite material layers of this embodiment includes an inner container 1, a container shell 3, two axial support members 5 and a spiral tube 6, and the inner container 1 passes Two axial support members 5 are installed in the container shell 3. A vacuum chamber 2 is formed between the inner container 1 and the container shell 3. Each axial support member 5 consists of a support shaft 12, a first support plate 13, and a support circle. The inner walls of the two ends of the container shell 3 are each fixed with a supporting shaft 12, the two supporting shafts 12 are arranged coaxially with the axis of the container shell 3, and each supporting shaft 12 is fixedly sleeved with a first supporting plate 13 , A support cylinder 14 is fixedly mounted on the outer wall at both ends of the inner liner 1, and the two support...

specific Embodiment approach 2

[0012] Embodiment 2: The metal lining layer 1-1 of this embodiment is made of aluminum alloy, and the ratio of the tensile yield strength to the elastic modulus of the aluminum alloy is F TY / E is at least 0.2%, and the elongation at break of the aluminum alloy is at least 11%. Such a design can meet the requirement of repeated use under low temperature conditions, and meet the requirement of repeated use for multiple times of aluminum alloy lining without being damaged due to low temperature becoming brittle. The other composition and connection relationship are the same as in the first embodiment. Specific implementation mode three: combination figure 2 Note that the thickness δ of the metal lining layer 1-1 in this embodiment is 0.5 mm to 8.0 mm. Such a design makes it easier to process thin aluminum alloy linings, thereby greatly reducing weight. The other composition and connection relationship are the same as those in the first or second embodiment. Specific embodime...

specific Embodiment approach 5

[0013] Embodiment 5: The liquid oxygen container in this embodiment further includes a normal temperature gas adsorbent 10, and the normal temperature gas adsorbent 10 is disposed on the inner wall of the container shell 3. Such a setting ensures that the outer layer of the vacuum chamber 2 is in a normal temperature environment during use, and small molecules are fully absorbed by the warm gas adsorbent, and the vacuum degree required in the vacuum chamber 2 is ensured. The other composition and connection relationship are the same as those in the first, second or fourth embodiment.

Abstract

The invention discloses a liquid oxygen container with a multi-layer vacuum thermal insulation layer and a fiber reinforced composite material layer, relates to a liquid oxygen container and solves the problems that the conventional liquid oxygen container is in a stainless steel structure and has the defects of high weight, low storage and transportation efficiency and high storage and transportation cost. A second supporting disc is fixedly sleeved on each supporting cylinder; a third supporting disc is fixedly sleeved on each second supporting disc; each third supporting disc is fixedly connected with the inner wall of a shell of the container in the circumferential direction; a liner consists of a metal liner layer, the fiber reinforced composite material layer and the multi-layer vacuum thermal insulation layer sequentially from interior to exterior; the fiber reinforced composite material layer is wound on the outer wall of the metal liner layer; and multi-layer vacuum thermal insulation layer is coated on the outer surface of the fiber reinforced composite material layer. The liquid oxygen container with the multi-layer vacuum thermal insulation layer and the fiber reinforced composite material layer is used for storing and transporting liquid oxygen.

Description

Technical field [0001] The invention relates to a container for storing and transporting liquid oxygen. Background technique [0002] As a high-efficiency oxidant, liquid oxygen is widely used in various fields of the national economy, such as steelmaking, medical oxygen stations, clean energy transportation, aerospace and other fields. Compared with the storage and transportation of high-pressure oxygen, the storage and transportation of low-temperature liquefied oxygen can effectively solve the problems of explosion and low storage and transportation efficiency, and realize safe and efficient storage and transportation. [0003] The container for storing and transporting cryogenic liquid oxygen needs to have an excellent thermal insulation layer structure. According to the different types of insulation, the insulation layer is divided into the following categories: single-layer or split-layer vacuum insulation, vacuum porous insulation and stacked insulation. For liquid oxygen c...
