Description
Technical Field
The invention relates to the technical field of low-temperature liquid transportation, in particular to a magnetic force adjustable 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.

the inner magnet and the outer magnet are both provided with coils, the coils are connected with a power supply, and the coils are used for adjusting the magnetic force of the inner magnet and the magnetic force of the outer magnet.
In one possible design, the system further comprises a control device electrically connected to the power supply, the control device being configured to regulate the voltage of the power supply in response to a change in the speed of the cryogenic vessel.
The low-temperature container is characterized by further comprising an acceleration acquisition device, wherein the acceleration acquisition device is electrically connected with the control device, the acceleration acquisition device is used for acquiring the acceleration of the low-temperature container and transmitting the acceleration to the control device, and the control device is used for adjusting the voltage of the power supply according to the acceleration.
In one possible design, the control device is provided with a preset value, and when the acceleration is lower than the preset value, the control device controls the voltage to keep an initial voltage value, and when the acceleration exceeds the preset value, the control device increases the voltage of the power supply.
In one possible design, when the acceleration exceeds a preset value, the control device increases the voltage of the power supply according to the magnitude of the acceleration, and the larger the acceleration, the larger the voltage of the power supply, the smaller the acceleration, and the smaller the voltage of the power supply.
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 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 invention has at least the following beneficial effects:
when the inner tube is filled with low-temperature liquid, the gravity center is lower, when the inner neck tube is set to be long and the tube wall is thin, and the low-cold-quantity leakage structure is formed, the load on the upper part of the thin and long inner diameter tube can be increased by shaking during transportation, and the low-temperature container is easy to be 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. It should be noted that, the magnetic force is utilized to fix the inner cylinder relative to the direct solid support structure, so that the leakage of cold energy through the solid support structure can be avoided.
After the coil is electrified, the outer magnet piece and the inner magnet piece can be magnetized. This is because electrons move around atomic nuclei to form magnetic poles, and a large number of atoms in the magnet are distributed according to a certain rule to form two poles of the magnet, but vibration breaks the regular distribution of atoms, so that the magnetism of the magnet is weakened. In order to ensure that enough magnetic force exists between the inner magnet and the outer magnet all the time, the coils can be used for magnetizing the inner magnet and the outer magnet at intervals. According to different liquid qualities in the Dewar, the voltage of the power supply can be flexibly adjusted, and then the current of the coil is adjusted, so that the magnetic force adjustable function of the inner magnet piece and the outer magnet piece is finally realized, and the electric double-coil magnetic force adjustable device is suitable for transportation of low-temperature liquids with different qualities.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
In the description of the present specification, it should be understood that the terms "upper", "lower", and the like used in the embodiments of the present invention are described in terms of the angles shown in the drawings, and should not be construed as limiting the embodiments of the present invention.

As shown in fig. 1 to 5, the embodiment of the invention provides a magnetic force adjustable low-temperature container, which comprises an outer cylinder 1 and an inner cylinder 2 arranged in the outer cylinder 1, wherein an outer neck pipe 5 is arranged at the top of the outer cylinder 1, an inner neck pipe 6 is arranged on the inner cylinder 2, the port of the outer neck pipe 5 is connected with the port of the inner neck pipe 6, so that a sealed space is formed between the outer cylinder 1 and the inner cylinder 2, a plurality of inner magnet pieces 4 are uniformly arranged outside the side wall of the inner cylinder 2, a plurality of outer magnet pieces 3 are uniformly arranged inside the side wall of the outer cylinder 1, and each inner magnet piece 4 is provided with one outer magnet piece 3 opposite to the outer magnet piece;
the inner magnet piece 4 and the outer magnet piece 3 are each provided with a coil 13, the coil 13 being connected to a power source, the coil 13 being used for adjusting the magnetic forces of the inner magnet piece 4 and the outer magnet piece 3.
When the inner cylinder 2 is filled with the low-temperature liquid 12, the gravity center is lower, and when the inner neck pipe 6 is of a low-cold-quantity leakage structure with a longer length and a thinner pipe wall, the load on the upper part of the thin and long inner diameter pipe 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 4 are uniformly arranged outside the side wall of the inner cylinder 2, a plurality of outer magnet pieces 3 are uniformly arranged inside the side wall of the outer cylinder 1, and each inner magnet piece 4 is provided with one outer magnet piece 3 opposite to the inner magnet piece. The inner magnet and the outer magnet generate attractive or repulsive magnetic force therebetween, so that the inner cylinder 2 can be secured without the inner cylinder 2 and the outer cylinder 1 contacting to prevent shaking thereof during transportation. It should be noted that, by fixing the inner cylinder 2 by magnetic force, the leakage of cold energy through the solid support structure can be avoided compared with the direct arrangement of the solid support structure.
The outer magnet piece 3 and the inner magnet piece 4 can be magnetized after the coil 13 is energized. This is because electrons move around atomic nuclei to form magnetic poles, and a large number of atoms in the magnet are distributed according to a certain rule to form two poles of the magnet, but vibration breaks the regular distribution of atoms, so that the magnetism of the magnet is weakened. In order to ensure that there is always sufficient magnetic force between the inner and outer magnets, the inner and outer magnets may be magnetized at intervals using the coil 13. According to the different quality of the liquid in the Dewar, the voltage of the power supply can be flexibly adjusted, and then the current of the coil 13 is adjusted, finally, the magnetic force adjustable function of the inner magnet piece and the outer magnet piece is realized, so that the device is suitable for transporting low-temperature liquid with different qualities.
It should be noted that the change in the mass of the cryogenic liquid may be caused by different volumes of the liquid in the inner cylinder 2, or may be caused by different types of cryogenic liquids, for example, when transporting liquid hydrogen, liquid helium or liquid nitrogen, the magnetic force is adjusted according to the type of cryogenic liquid.
In this embodiment the inner neck is provided with an overpressure discharge 11, where the overpressure discharge 11 is used for installing a safety valve to avoid an excessive internal pressure.
In some embodiments of the invention, the cryogenic container further comprises a control device electrically connected to the power supply, the control device being configured to regulate the voltage of the power supply in response to a change in the speed of the cryogenic container.
In this embodiment, the reason for shaking of the inner cylinder 2 during transportation of the cryogenic container is mainly from the change in speed, and the shaking of the inner cylinder 2 is not large when the transportation vehicle is operating stably and at a uniform speed. Thus, the greater the velocity change of the cryogenic vessel, the greater the support force that needs to be provided by the magnetic force. A control device is arranged, and the control device adjusts the voltage of the power supply according to the speed change of the low-temperature container, so as to adjust the current of the coil 13 to control the magnetic force of the inner magnet piece and the outer magnet piece. By the arrangement, energy sources can be saved, and the stability and reliability of the low-temperature container are improved.
In some embodiments of the present invention, the system further comprises an acceleration acquisition device, wherein the acceleration acquisition device is electrically connected with the control device, the acceleration acquisition device is used for acquiring the acceleration of the low-temperature container, transmitting the acceleration to the control device, and the control device is used for adjusting the voltage of the power supply according to the acceleration.
In this embodiment, the control device adjusts the voltage of the power supply by the acceleration acquired by the acceleration acquisition device. The control device is based on a PLC control system or a DCS control system.

In this embodiment, the acceleration acquisition device acquires acceleration, that is, a change in the speed of the cryogenic container. In order to save energy, when acceleration change is not obvious, controlling the voltage of the power supply to keep an initial voltage value, and providing stable supporting magnetic force; when the acceleration change is significant, the power supply voltage is controlled to be increased to increase the magnetic force support in order to protect the cryogenic container. So set up, when acceleration change is not big, take energy-conserving scheme, voltage is lower initial voltage value, when acceleration change is big, increase voltage in order to protect the cryogenic vessel, when acceleration reduces and resumes less steady state, continue to provide magnetic force with initial voltage value.
In some embodiments of the present invention, when the acceleration exceeds a preset value, the control device increases the voltage of the power supply according to the magnitude of the acceleration, and the larger the acceleration, the larger the voltage of the power supply, the smaller the acceleration, and the smaller the voltage of the power supply.

In this embodiment, the baffle 8 can shield the evaporated cold air in the inner cylinder 2, and the flow cross-sectional area of the cold air is smaller, so that the convection heat exchange between the cold air and the upper end of the baffle 8 with higher temperature is greatly limited, thereby reducing the loss of the cold energy of the inner cylinder 2.
In some embodiments of the invention, the inner neck 6 is perforated with a filling tube 9, the filling tube 9 being used to fill the inner barrel 2 with cryogenic liquid 12.
In some embodiments of the invention, the inner neck 6 is perforated with a level gauge 10, the level gauge 10 being used to measure the level of the cryogenic liquid 12 in the inner drum 2.
