Magnet temperature control device of nuclear magnetic resonance equipment

Abstract

The invention discloses a magnet temperature control device for nuclear magnetic resonance equipment, relates to the technical field of the nuclear magnetic resonance equipment, and solves the problems that an existing temperature control device adopts hot air blowing heating, the hot air is mostly directional incoming air, only single-side blowing heating can be performed on the magnet, and blowing dead angles exist. The magnet temperature control device of the nuclear magnetic resonance equipment comprises a motor, an arc-shaped clamping plate, adsorption strip plates and a stress push plate, the motor comprises a sector gear, the middle of the top end of an arc-shaped shell is provided with the motor in a supporting mode, and a rotating shaft of the motor is sleeved with a sector gear;the arc-shaped shell comprises a transverse support positioning shaft; and two transverse support positioning shafts are symmetrically supported and welded at the root positions of the left side and the right side of the inner space of the arc-shaped shell. The front and rear groups of adsorption strip plates can intermittently slide back and forth oppositely in a reciprocating manner to adsorb and clean deposited dust swept from the inner wall of the bottom of the arc-shaped shell, so that the trouble of manual cleaning is saved.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance equipment, in particular to a magnet temperature control device for nuclear magnetic resonance equipment. Background technique [0002] Nuclear Magnetic Resonance refers to a physical process in which the atomic nucleus with a non-zero magnetic moment is under the vertical action of the main magnetic field and the radio frequency field, and the spin energy level undergoes Zeeman splitting, and the nucleus absorbs radio frequency energy. It has other detection methods such as non-destructive testing and rich testing information. Incomparable many advantages. The magnetic field strength of the permanent magnet magnetic field will change as the ambient temperature changes, thus affecting the detection of nuclear magnetic resonance signals. The application range of nuclear magnetic resonance technology is very wide, covering many fields such as biology, medicine, chemistry, food, p...

AI Technical Summary

Problems solved by technology

[0004] Existing temperature control devices generally use hot air to blow and heat, and most of the hot air is directional wind, which can only be blown and heated on one side of the magnet. The heating of the magnet is not uniform enough, and the temperature difference is large. In addition, the wind blowing and circulating heating will increase the amount of dust accumulation inside the magnet and the housing. Manual cleaning is required on a regular basis. The operation is cumbersome and inconvenient, time-consuming and laborious.
