Abstract
The invention discloses a magnetic separation superconducting magnet system which comprises a superconducting coil arranged in a heat shielding case, wherein the heat shielding case is arranged in a room temperature vacuum container. The magnetic separation superconducting magnet system is characterized in that the room temperature vacuum container is formed by sealing a non-magnetic material inner case, a magnetic material outer case and magnetic end plates at two ends. The magnetic separation superconducting magnet system has simpler structure, thereby having light weight and small size; moreover, the consumption is less, thus the cost is low; and because the structures of the outer case and the end plates are simpler, the processing difficulty is reduced, the processing workload is decreased, the working efficiency is improved, and the processing cost is lowered.
Description
Technical field
The present invention relates to a kind of superconducting magnet, is a kind of solenoid type superconducting magnet that is used for fields such as ore dressing or purification of water quality specifically.
Background technology
Superconducting magnet makes the service area of magnet have higher magnetic field intensity owing to adopt superconductivity wire, thereby has application widely, for example medical MRI imaging, mine ore dressing or purification of water quality.
In superconducting magnet, because superconducting coil need work under enough low low temperature environment, superconducting magnet is soaked by liquid cryogenic fluid usually and is cooled off or cool off superconducting coil with the cold of refrigeration machine in the mode of solid conduction.In order to reduce the low-temperature space loss of refrigeration capacity, the one or more heat shielding covers of the superconducting coil outer setting of superconducting magnet, and be installed in jointly in the room temperature vacuum tank of the sealing that constitutes by inner casing, shell and end plate, this room temperature vacuum tank adopts non-magnetic materials such as stainless steel or aluminium alloy usually.
In superconducting magnet, in order to realize the uniformity requirement of central magnetic field, with reduce magnetic field and escape pollution environment, and magnetic field escapes the energy loss that causes and causes the central task magnetic field intensity to weaken, in existing magnetic separator, also adding outside the room temperature vacuum tank that the non-magnetic material is made has magnetic conductivity shell and magnetic conductivity end plate, is the magnetic channel of design to be grown up in the solenoid profile.This outside the room temperature vacuum tank that the non-magnetic material is made the structure of extra again additional guide magnetic material end plate and shell, can significantly increase the volume and weight of superconducting magnet system.
Publication number is that the Chinese utility model patent document of CN201294130Y discloses " a kind of MRI superconducting magnet system ", it is a kind of medical MRI superconducting magnet system, the inner casing of its room temperature vacuum tank adopts the non-magnetic material, shell then adopts magnetic conductive material, and end plate adopts composite construction, annulus with housing contacts in the compound end plate is a magnetic conductor, and the annulus that contacts with inner casing is a non-magnetizer, can also add on the non-magnetizer that magnetic inductive block being set.This medical MRI superconducting magnet room temperature vacuum tank structure, though weight and volume can alleviate, yet this compound end plate that is made of magnetic conductor and non-magnetizer concentric ring because special composite construction, has therefore brought difficulty to processing.
Summary of the invention
In order to solve superconducting magnet structure complexity in the prior art, and adopt the big deficiency of compound end plate difficulty of processing, the superconducting magnet system of purpose of the present invention with regard to being to provide a kind of novel magnetic separation to use, this system configuration is simple, can satisfy magnet working area field uniformity and externally magnetic field escape few requirement.
The present invention adopts following technical scheme: a kind of magnetic separation superconducting magnet system, comprise the superconducting coil that places the heat shielding cover, the heat shielding cover is contained in the room temperature vacuum tank, and described room temperature vacuum tank is sealed to by the magnetic conductivity end plate at non-magnetic material inner, magnetic conductive material shell and two ends.
For by adjust magnetic field in the form at end plate place to adjust the uniformity of magnetic field in central task district, described magnetic conductivity end plate also is mounted with one or more magnetic conductivity additional end plates outward.The magnetic conductivity additional end plates can be fixed on the described magnetic conductivity end plate by bolt or screw, and this mounting means is convenient to adjust at any time as required magnetic conductivity additional end plates quantity.
Described magnetic conductive material can be high magnetic conductive material, for example electrical pure iron, steel alloy.
This superconducting magnet system of the present invention, its room temperature vacuum tank, except that inner casing adopts the non-magnetic material, shell and end plate all directly adopt magnetic conductive material, make the room temperature vacuum tank end plate and the shell of magnetic conductivity directly form the outer magnetic channel of solenoid, compare with the structure of extra additional guide magnetic shell and end plate outside non-magnetic room temperature vacuum tank, still adopt the superconducting magnet system of the compound end plate of non-magnetic material and magnetic conductive material formation to compare with medical MRI, realizing under same technique effect (reduce magnetic field and escape and improve the uniformity of magnetic field of the service area) prerequisite, its structure is simpler, thereby not only in light weight, volume is little; And since material usage few so the cost of material is low; Because shell and tip plate configurations are simple, have also reduced difficulty of processing, the labor content of minimizing has improved operating efficiency, has reduced processing cost.
