Problems solved by technology

[0002] In the past ten years, in order to ensure the normal operation of high-temperature superconducting radio frequency coils, the technology of using liquid nitrogen vaporization to absorb heat to achieve cooling has developed rapidly. It is easy to use and has a large flow rate, but the liquid nitrogen pump is not compatible with the magnetic resonance system. The infusion tube cannot be used with the high-temperature superconducting radio frequency coil during the infus

Abstract

The invention discloses a liquid nitrogen filling device and a liquid nitrogen filling system. The liquid nitrogen filling device comprises a filler (1), a liquid nitrogen tank (2), a liquid feeding pipe (3), a liquid discharging pipe (4), an electromagnetic pump system (18), an air feeding device and a safety device, wherein the liquid discharging pipe (4) and the liquid feeding pipe (3) as well as the filler (1) are of a split type structure, and are in movable connection state, a filter device (6) is arranged at one end of the liquid feeding pipe (3), a rapid joint (7) is arranged at one end of the liquid discharging pipe (4), a high-temperature superconduction radio-frequency coil (8) is arranged at one end of the rapid joint (7), a control device is arranged at the other end of the high-temperature superconduction radio-frequency coil (8), an automatic air bleeding device (19) is arranged at one end of the control device, and the filler (1) is connected with the liquid nitrogen tank (2) by a sealing-fixing device. Due to the adoption of the structure, the high-temperature superconduction radio-frequency coil can be filled with liquid automatically, the safety of operators is ensured, the labor intensity of workers is alleviated, the purpose of long-time continuous work is realized, and liquid nitrogen filling device can be compatible with a magnetic resonance system.

Description

technical field [0001] The invention relates to a liquid nitrogen filling device, in particular to a liquid nitrogen filling device for a magnetic resonance imaging system. The invention also relates to a liquid nitrogen filling system. Background technique [0002] In the past ten years, in order to ensure the normal operation of high-temperature superconducting radio frequency coils, the technology of using liquid nitrogen vaporization to absorb heat to achieve cooling has developed rapidly. It is easy to use and has a large flow rate, but the liquid nitrogen pump is not compatible with the magnetic resonance system. The infusion tube cannot be used with the high-temperature superconducting radio frequency coil during the infusion process. The liquid nitrogen tank is pressurized by injecting air during the infusion process, causing a large amount of water vapor When it enters the liquid nitrogen tank, it will freeze and block the liquid nitrogen transmission. The infusion...
