Description

Technical Field

[0001] The utility model belongs to the technical field of magnets, and particularly relates to a high-temperature corrosion-resistant neodymium magnet. Background Art

[0002] The existing neodymium iron boron magnet has poor surface corrosion resistance. When used for a long time, the surface of the neodymium iron boron magnet is corroded, and the surface of the neodymium magnet is damaged, affecting the service life of the neodymium iron boron magnet. Among them, the "corrosion-resistant magnet" disclosed in the application number "CN202320346645.5" is also an increasingly mature technology. A corrosion-resistant paint layer, a wear-resistant layer, an organosilicon insulating layer, a galvanized layer, and a body are arranged in sequence. The thickness of the organosilicon insulating layer is greater than that of the wear-resistant layer, the thickness of the wear-resistant layer is greater than that of the galvanized layer, and the thickness of the galvanized layer is greater than that of the corrosion-resistant paint layer. Through the above structure, the body can be effectively protected, and the service life of the magnet can be effectively extended. However, the device still has the following defects: when in use, there is a lack of a support structure inside the magnet, and when it is impacted, it is easy to damage the magnet structure and form fractures. At the same time, the too-thick protective layer affects the magnetic force, and the external high temperature affects the magnet during the use of the magnet. Summary of the Utility Model

At the same time, the too-thick protective layer affects the magnetic force, and the external high temperature affects the magnet during the use of the magnet.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: It includes a support frame and a magnet body. The support frame is composed of an outer support ring, an inner support ring, and I-shaped support columns. The inner support ring is arranged inside the inner circle of the magnet, the outer support ring is coated and arranged outside the magnet body, a high-temperature-resistant ceramic layer is arranged on the outer wall of the support frame, an anti-static steel layer is arranged on the outer wall of the high-temperature-resistant ceramic layer, and wear-resistant silicon carbide is arranged on the outer wall of the anti-static steel layer.

[0005] In an implementation scheme of the high-temperature corrosion-resistant neodymium magnet of the utility model, the outer support ring, the inner support ring, and the I-shaped support columns are all made of NdFeB magnetic steel material, and both ends of the I-shaped support columns are respectively fixedly installed at the top and bottom of the inner wall of the outer support ring and the top and bottom of the outside of the inner support ring.

[0006] In this scheme, the outer support ring and the inner support ring protect the outside and inside of the magnet. The space between the outer support ring and the inner support ring is supported by the I-shaped support columns, improving the overall strength of the support frame.

[0007] In an implementation scheme of the high-temperature corrosion-resistant neodymium magnet of the utility model, a stabilizing and strengthening plate is filled between adjacent I-shaped support columns.

[0008] In this solution, the structural stability between adjacent I-shaped support columns is improved by means of a stabilizing reinforcement plate.

[0010] In this solution, the space between the I-shaped support columns is supported by the corrugated cross bars. At the same time, when the outside is impacted, the corrugated cross bars cooperate with the stabilizing reinforcement plate to disperse the impact force and improve the impact resistance of the equipment.

[0011] In an embodiment of a high-temperature corrosion-resistant neodymium magnet of the present utility model, a galvanized anti-corrosion coating is provided on the outside of the wear-resistant silicon carbide.

[0012] In this solution, the outside of the wear-resistant silicon carbide is protected from corrosion by the galvanized anti-corrosion coating, and the support frame and the magnet body are protected by the wear-resistant silicon carbide.

[0013] In an embodiment of a high-temperature corrosion-resistant neodymium magnet of the present utility model, the thickness of the galvanized anti-corrosion coating layer is 7 to 10 millimeters.

[0014] In this solution, the rust resistance and corrosion resistance are improved by the galvanized anti-corrosion coating to protect the outside of the equipment.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1) By providing a galvanized anti-corrosion coating, the outside of the wear-resistant silicon carbide is protected from corrosion. The support frame and the magnet body are protected by the wear-resistant silicon carbide. At the same time, the wear of the high-temperature resistant ceramic layer is avoided. When exposed to high temperatures, the high-temperature resistant ceramic layer reduces the external heat conduction amount to protect the support frame and the magnet body and prevent the magnetic force from decreasing due to excessive temperature.

[0017] 2) The outer support ring and the inner support ring in the support frame protect the outside and inside of the magnet. The space between the outer support ring and the inner support ring is supported by the I-shaped support columns to improve the overall strength of the support frame. At the same time, the magnetic force of the equipment is improved through the support frame. The space between the I-shaped support columns is supported by the corrugated cross bars. When the outside is impacted, the corrugated cross bars cooperate with the stabilizing reinforcement plate to disperse the impact force and improve the impact resistance of the equipment.
