Description

Technical Field

[0001] The utility model relates to the technical field of cooling mechanisms, in particular to an AC demagnetization coil cooling mechanism. Background Art

[0002] The demagnetizer is used to eliminate or reduce the residual magnetism of magnetic materials to prevent these materials from having an adverse effect on subsequent processing or use. The demagnetizer consists of a frame and a demagnetization coil inside the frame. When in use, heat will be generated in the demagnetization coil.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-4An AC demagnetization coil cooling mechanism is shown, comprising a demagnetization coil outer frame 1, a cooling assembly 2 is arranged on the front side of the demagnetization coil outer frame 1, the cooling assembly 2 comprises a refrigerated dryer 201 arranged on the front side of the demagnetization coil outer frame 1, a delivery pipe 202 is arranged at the output end of the refrigerated dryer 201, a pneumatic triplet 203 is arranged at one end of the delivery pipe 202, an air inlet pipe 204 is arranged at one end of the pneumatic triplet 203 away from the delivery pipe 202, the air inlet pipe 204 is inserted and connected to the front side of the demagnetization coil outer frame 1, a fixing assembly for fixing the position of the pneumatic triplet 203 is arranged on the back side of the refrigerated dryer 201, and a heat dissipation hole 3 for exhausting gas is opened on the front side of the demagnetization coil outer frame 1.

[0020] It should be noted that the demagnetization coil outer frame 1 is a frame body, and a demagnetization coil is wound inside. When in use, the magnetic domains inside the workpiece are constantly rearranged and disturbed by the alternating magnetic field applied by the AC demagnetization coil, resulting in a reduction or disappearance of the macroscopic magnetic moment of the workpiece, ultimately achieving the purpose of demagnetization. The refrigerated dryer 201 is a HKS refrigerated dryer, which is used to compress, cool and dry the gas when in use; the pneumatic triplex 203 is an AC2000 pneumatic triplex, which removes impurities in the gas, such as dust, particles and moisture, through its internal filtering structure when in use, thereby removing moisture from the gas input into the demagnetization coil outer frame 1 to prevent moisture from entering the demagnetization coil outer frame 1. The heat dissipation holes 3 are used to discharge the gas inside the demagnetization coil outer frame 1 out of the demagnetization coil outer frame 1.

[0021] Furthermore, when it is necessary to cool the demagnetization coil inside the demagnetization coil outer frame 1, first open the refrigerated dryer 201, compress, cool and dry the gas through the refrigerated dryer 201, and then transport the gas to the inside of the pneumatic triplet 203 through the delivery pipe 202 at its output end, and filter the moisture in the gas through the pneumatic triplet 203, and finally transport the cooling gas with moisture removed to the inside of the demagnetization coil outer frame 1 through the air inlet pipe 204 on one side of the pneumatic triplet 203, and cool the demagnetization coil inside the demagnetization coil outer frame 1, and finally, the gas exchanged with heat by the demagnetization coil is discharged from the demagnetization coil outer frame 1 through the heat dissipation hole 3.

[0022] Specifically, the fixing assembly includes a connecting member 4 for limiting the moving direction of the pneumatic triplet 203 and a positioning member 5 for limiting the movement of the pneumatic triplet 203 .

[0023] Specifically, the connector 4 includes a positioning block 401 fixedly connected to the back of the refrigerated dryer 201, a fixing block 402 fixedly connected to the front of the pneumatic triplex 203, a limiting groove is provided on the back of the positioning block 401, and the fixing block 402 is inserted and connected inside the limiting groove.

[0024] It should be noted that the positioning block 401 can be fixed to the back of the refrigerated dryer 201 by welding or bolts, and the fixed block 402 can be fixed to the front of the pneumatic triplex 203 by welding or bolts. The limiting groove opened on the back of the positioning block 401 is adapted to the fixed block 402. When in use, the fixed block 402 is inserted into the limiting groove, and the moving direction of the fixed block 402 is limited by the limiting groove.

[0025] Specifically, the positioning member 5 includes a clamping hole 501 symmetrically opened on the inner walls on both sides of the limiting groove, the clamping blocks 502 are symmetrically inserted and connected on both sides of the fixed block 402, the clamping block 502 is clamped in the inside of the clamping hole 501, one side of the clamping block 502 is fixedly connected to a pushing block 503, one side of the pushing block 503 is fixedly connected to an elastic block 504, cavities 6 are symmetrically opened on both sides of the fixed block 402, the pushing block 503 is inserted and connected in the inside of the cavity 6, and the elastic block 504 is fixedly connected to the inner wall on one side of the cavity 6.

[0026] It should be noted that the push block 503 is adapted to the cavity 6, so that the push block 503 can slide inside the cavity 6 when in use. The elastic block 504 is made of rubber material, which has a deformable property. When in use, when the elastic block 504 is squeezed by the push block 503, it will be deformed, so that the push block 503 can continue to move toward one side of the elastic block 504. When the elastic block 504 loses the squeezing of the push block 503, the elastic block 504 will be deformed, driving the push block 503 to move toward the side away from the elastic block 504. The card block 502 is fixedly connected to one side of the push block 503, and the card block 502 is driven to move by the push block 503 when in use.

[0027] It should be noted that when the position of the pneumatic triplex 203 needs to be fixed, the block 502 is first pressed, and the block 502 drives the push block 503 to be squeezed toward one side of the elastic block 504. The elastic block 504 is squeezed and deformed, so that one side of the block 502 is flush with the outer wall of the fixed block 402, and then the fixed block 402 is inserted into the inner part of the limiting groove. When one side of the block 502 fits with the inner wall of one side of the limiting groove, the pressing of the block 502 is released, and the block 502 is blocked by the inner wall of the limiting groove and cannot move. When the block 502 is moved to align with the card hole 501, the elastic block 504 The deformation is restored, and the pushing block 503 is pushed toward one side of the blocking block 502. The blocking block 502 is driven by the pushing block 503 so that the blocking block 502 moves into the inside of the blocking hole 501. The restriction of the blocking block 502 makes the fixing block 402 unable to move further, so that the position of the pneumatic triplex 203 is fixed by the fixed block 402 that cannot move, avoiding the need to continuously tighten the bolts to fix the pneumatic triplex 203 when installing it. When the pneumatic triplex 203 needs to be disassembled, the blocking block 502 is directly moved out of the blocking hole 501, and the fixing block 402 is pulled out of the limiting groove.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
