Description
Technical Field
The utility model relates to the technical field of low-temperature liquid transportation, in particular to a magnetic force constrained low-temperature container.
Background
With the development of technology, cryogenic technology has an increasing number of application scenarios, and cryogenic containers for storing cryogenic liquids, also called dewars, are often used. The prior Dewar adopts a sandwich structure, the inner cylinder and the outer cylinder are vacuumized, and the inner cylinder is hung on the upper part of the outer cylinder through a neck pipe. The main modes of cold loss of the structure are conduction heat leakage and convection heat exchange at the neck pipe position.
Because the inner cylinder is hung on the outer cylinder through the neck pipe, when the inner cylinder is filled with low-temperature liquid, the gravity center of the inner cylinder is deviated, the root of the neck pipe can bear larger bending moment due to shaking in the transportation process, and the neck pipe has enough strength, so that the neck pipe cannot be too long and the pipe wall cannot be too thin. However, this may make the conduction leakage at the neck more significant, especially for 20K liquid hydrogen or 4K liquid helium, and more sensitive to the leakage at the neck.
There is a need for a cryogenic container that has sufficient structural strength to withstand road transport sloshing and that has less heat leakage.

In one possible design, the inner magnet piece is near the bottom of the inner barrel and the outer magnet piece is near the bottom of the outer barrel.
In one possible design, the outer cylinder is provided with a vacuum outlet for evacuating the sealed space.
In one possible design, a baffle is provided in the middle of the inner neck, and the baffle is used for reducing the cooling capacity loss of the inner cylinder.
In one possible design, the inner neck tube is perforated with a liquid filling tube for filling the inner tube with a cryogenic liquid.
In one possible design, the inner neck tube is perforated with a level gauge for measuring the level of cryogenic liquid in the inner tube.
In one possible design, the baffle is provided with a first through hole through which the filler pipe passes without contacting the baffle to prevent heat transfer.
In one possible design, the baffle is provided with a second through hole through which the gauge passes and is not in contact with the baffle to prevent heat transfer.
In one possible design, the poles of the opposite sides of the inner and outer magnet pieces are the same or are different.
In one possible design, the magnetic forces generated between each pair of the inner magnet pieces and the outer magnet pieces are the same.
Compared with the prior art, the utility model has at least the following beneficial effects:
when the inner tube is filled with low-temperature liquid, the gravity center is lower, and when the inner neck tube is arranged to be of a low-cold-quantity leakage structure with longer length and thinner tube wall, the load on the upper part of the thin and long inner diameter tube can be increased by shaking during transportation, so that the low-temperature container is easily damaged to cause cold quantity and low-temperature fluid leakage. Therefore, a plurality of inner magnet pieces are uniformly arranged outside the inner cylinder side wall, a plurality of outer magnet pieces are uniformly arranged inside the outer cylinder side wall, and each inner magnet piece is provided with one outer magnet piece opposite to the inner magnet piece. The inner magnet and the outer magnet generate attractive or repulsive magnetic force, so that the inner cylinder can be stabilized under the condition that the inner cylinder and the outer cylinder are not contacted, and shaking of the inner cylinder in transportation can be prevented.
