Abstract
The utility model relates to a device for generating high strength non-uniform alternating magnetic field from a roller type rotary permanent magnet. A U-shaped magnet made of permanent magnetic material with high magnetic energy product is arranged in a nonmagnetic sleeve barrel, wherein the permanent magnetic material is mixed with rare earth material. The external side of the U-shaped permanent magnet is fixed with a pole head. The nonmagnetic sleeve barrel can horizontally and vertically rotate under the drive of a motor. The magnetic field created by the device can be used for the requirement of medical magnetic therapeutic equipment. At the same time, the utility model can also be popularized and used in the aspects of industrial magnetic separation technique and biologic magnetization in the field of farm subsidiary product.
Description
Technical field
This utility model relates to the device that is produced high strength, non-homogeneous alternating magnetic field by the roll-type rotating permanent magnet.It can provide a high strength, an alternating intense magnetic field heterogeneous in bigger spatial dimension, this device can be widely used in device for magnetotherapy in the medical treatment, simultaneously also can be in industry be applicable aspect the biology magnetization in magnetic separation technique and the agricultural avocation.
Technical background
Magnetic field is used for to people's existing history remote of curing the disease.Ancient Times in China is just relevant for the record of curing the disease with Magnetitum.Some external scientists of 20 beginnings of the century have just begun the mechanism research of curing the disease in magnetic field, though disputable aspect the mechanism of magnetic therapy, magnetic field is undisputable fact to the positive effect that the affected part has activating blood circulation to dissipate blood stasis, anti-inflammatory analgetic.Therefore, early 1980s, China once started a magnetic therapy climax, emerging in large numbers of a large amount of magnetic therapy curative effect statistical reports and paper, cause varied ground magnetic therapeutic device to be full of market, various places, after particularly the neodymium iron boron of high energy product (NdFeB) permanent magnet material was come out in nineteen eighty-three, magnetic field therapy is pushed to a new climax, but at that time because the monolithic volume of permanent magnet material is less, cost an arm and a leg, so most of magnetic therapy products all are limited to small-sized magnetic therapeutic device, therapeutic domain also usually is confined to the skin shallow-layer in affected part.Along with the development of permanent magnet material, magnetic energy product can be produced in enormous quantities above the neodymium iron boron of 40MGOe at present, and price also descends significantly, provides good basis for manufacturing and designing large-scale high field strength magnets.But because that magnetic field intensity decay in air is express, very low owing to the conventional permanent magnet magnetic field intensity simultaneously, so magnetic field can only permeate the top layer, so magnetotherapy effect is all not obvious.Chinese patent (application number: 88216746.4) " electronic magnetotherapy ", Chinese patent (application number: 86206534) " Magnetic rotator for medical freatment " and United States Patent (USP) (application number: 4537.181) " be used for non-surgery operation and eliminate the sedimentary magnetic device of calcium in the human body ", with the United States Patent (USP) is example, its magnetic field intensity only reaches 50 Gausses, only work at shallow-layer in magnetic field, all owing to magnetic field intensity is too low, thereby can not be used widely.Along with the development of permanent magnet material, after especially the high energy product permanent magnet material was come out in nineteen eighty-three, can produce the permanent magnet material that magnetic energy product surpasses 40MGOe at present, for producing, this utility model device provides good material base.
Summary of the invention
The purpose of this utility model is to manufacture and design by the roll-type rotating permanent magnet to produce high strength, the device of non-homogeneous alternating magnetic field, be mixed with the Nd-Fe-B permanent magnet of the high energy product of rare earth material by employing, use main pole special shape and structure, make device that non-homogeneous high-intensity magnetic field from hundreds of to Gausses up to ten thousand can be provided, having overcome traditional permanent magnetism can only provide the weakness of tens gauss magnetic fields, the magnetic field EFFECTIVE RANGE is reached about 1 meter, thereby used motor-driven to form a high strength simultaneously, non-homogeneous alternating magnetic field makes the magnetotherapy effect in magnetic field have one greatly to improve in the more traditional magnetic therapy of degree of depth range.Thereby greatly expanded the scope of application aspect the biology magnetization in the magnetic separation technique and agricultural avocation in treatment in medical treatment, rehabilitation and the industry.
This utility model is to produce high strength by the roll-type rotating permanent magnet, the device of non-homogeneous alternating magnetic field, it is by in an external diameter is 380～550 millimeters no magnetic urceolus (5), install the horseshoe type main pole (3) that a neodymium iron boron that is mixed with the high energy product of rare earth material is made, placing main pole (3) top to make by ferrocobalt under cartridge (4) effect, formed a high strength magnetic field heterogeneous, main pole (3) is by the both sides that place the yoke of being made by electrical pure iron (2), rotating shaft (8) is through in the middle of the yoke (2), rotating shaft (8) two ends cooperate with bearing and link to each other with motor, under motor-driven, form a high strength, alternating magnetic field heterogeneous.

The specific embodiment
Manufacturing is by the device of roll-type rotating permanent magnet generation high strength, non-homogeneous alternating magnetic field, and it is made up of rotating shaft (8), yoke (2), main pole (3), cartridge (4), urceolus (5), end cap (6), support (7), chassis (1).We are in 380 millimeters no magnetic urceolus of diameter, inner core is to make horseshoe type main pole (3) by the neodymium iron boron of the high energy product that is mixed with rare earth material (NdFeB), yoke (2) that electrical pure iron is made and rotating shaft (8) are formed, main pole (3) has interacted with the cartridge (4) that places the top to make of ferrocobalt and has gathered flux interaction, forms a high strength, magnetic field heterogeneous.Main pole (3) is by the both sides that are loaded on yoke (2), and rotating shaft (8) is through in the middle of the yoke (2), and rotating shaft (8) two ends cooperate with bearing and link to each other with motor, under motor-driven, form a high strength, alternating magnetic field heterogeneous.
This utility model provides for various different application purposes, can be mixed with the high energy product permanent magnet of different rare earth materials, use main pole special shape and structure, make magnet size reach 380～550 millimeters of diameters (comprising the rotating shaft elongate axis), make device that high-intensity magnetic field from hundreds of to Gausses up to ten thousand can be provided.The EFFECTIVE RANGE in magnetic field can reach about 1 meter, thereby has greatly expanded the scope of application aspect the biology magnetization in the magnetic separation technique and agricultural avocation in treatment in medical treatment, rehabilitation and the industry.
