[0002] In the field of materials science and engineering, strong magnetic materials play an important role in many applications due to their unique magnetic properties. However, due to the mutual attraction of strong magnetic materials, it is often a challenge to separate them for easy installation of equipment or subsequent processing. Existing methods, such as mechanical prying or manual separation, are not only inefficient, but may also cause damage to the strong magnetic materials and affect their performance. How to achieve lossless separation of strong magnetic materials is a difficult problem that needs to be solved. Utility Model Content

[0006] After adopting this technical scheme, the metal sheet is prepared into a hollow sealed metal capsule. The sealed metal capsule prepared from the metal sheet is thin and has a certain hardness, so it can easily enter between two strong magnetic materials. Then, by passing a medium into the metal capsule to expand the metal capsule, the two strong magnetic materials can be separated. The gap generated after the separation of the strong magnetic materials can be stuck in other separation equipment, thereby realizing the lossless separation of the strong magnetic materials and effectively improving the separation efficiency of the strong magnetic materials.

[0010] After adopting this technical solution, the thickness of the 304 stainless steel sheet is 0.3mm, which allows the composed metal capsule to easily enter between the two strong magnetic materials.

[0011] Preferably, the 304 stainless steel sheet is a rectangular structure, and the length of the 304 stainless steel sheet is 650 mm-750 mm, and the width of the 304 stainless steel sheet is 40 mm-150 mm.

[0012] Preferably, the length of the connecting pipe is 300 mm.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. This technical solution prepares the metal sheet into a hollow sealed metal capsule. The sealed metal capsule prepared by the metal sheet is thin and has a certain hardness, so it can easily enter between two strong magnetic materials.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] Example 1

[0024] like Figure 1 As shown, a metal capsule includes a sealed metal capsule composed of a metal sheet 1, an interface is provided on the sealed metal capsule, the interface is connected to a connecting pipe 2, and the connecting pipe 2 is connected to a joint 3.

[0025] In this embodiment, the metal sheet 1 is a stainless steel sheet.

[0026] In this embodiment, the stainless steel sheet is a 304 stainless steel sheet, and the thickness of the 304 stainless steel sheet is 0.3 mm.

[0027] In this embodiment, the length of the connecting pipe 2 is 300 mm.

[0028] In this embodiment, the connecting pipe 2 is a stainless steel pipe with a diameter of 3 mm.

[0029] In this embodiment, the 304 stainless steel sheet is a rectangular structure. The metal capsules in this embodiment have four sizes, as shown in Table 1:

[0030] Table 1

[0031]

[0032] The method for preparing the metal capsule comprises the following steps:

[0033] S1: Welding two metal sheets 1 into a sealed metal capsule (the specific welding method should be a method with a small thickness at the welding point, such as laser welding, etc., to minimize the gap between the two metal sheets 1 so that the metal capsule can be smoothly inserted between the strong magnetic materials);

[0034] S2: sealingly connecting the connecting pipe 2 to the sealing metal bag;

[0035] S3: Connect the connecting tube 2 and the connector 3 to obtain the metal capsule described in Example 1 or 2.

[0036] Example 2

[0037] This embodiment is basically the same as embodiment 1 except that: Figure 2 As shown, the end of the metal sheet 1 in this embodiment is a sloped structure.

[0038] Test 1:

[0039] In order to verify the pressure resistance of the metal capsule and ensure that it has sufficient pressure bearing capacity to separate strong magnetic materials, the metal capsule is subjected to a pressure test. The expected pressure value of this test is 35Mpa. The size of the test metal capsule is 724*99mm. The test process is as follows:

[0040] 1. Tooling preparation: Use 2 steel plates made of 45# steel and 60mm thick to process the milling grooves according to the product size, and then clamp them together; use 18 M30 bolts to reinforce them around.

[0041] 2. Preparation of pressurizing equipment: professional pneumatic pressurizing machine + pressure gauge with a water pressure of 60Mpa. Replace the joint with the same size as the pressurizing equipment to connect the test product.

[0042] 3. Testing

[0043] Open the pressure valve and pressurize at 5Mpa intervals of 5Mpa in the order of 5Mpa-10Mpa-15Mpa-20Mpa-25Mpa-30Mpa-35Mpa. No leakage or deformation was found at 35Mpa. Then further try to reach the maximum pressure of 50Mpa. Continue to pressurize at 5Mpa intervals until 50Mpa. No leakage, water leakage or damage. After holding the pressure for more than 15S, gradually reduce the pressure to 0Mpa, disassemble the tooling, take out the product, and the product expands slightly after the test, and the welds around are intact without damage.

[0044] The above-mentioned pressure resistance test was also carried out on metal bags with sizes of 724*99mm, 699*79mm, 699*49mm, and 699*51mm. The experimental results showed that they could withstand a pressure of 50Mpa. However, a pressure resistance test was carried out on a 304 stainless steel sheet with a thickness of 0.3mm, and the results showed that it could only withstand a pressure of 5Mpa.

[0045] Test 2

[0046] The metal bladder can be used repeatedly, so test 2 is a cyclic pressurization test:

[0047] The size of the metal bladder is 724*99mm. Put it into the test environment and pressurize it from 0 to 50MPA for 15 seconds at each 5MPA (using large-scale water pressure testing equipment and pressurized water injection). After reaching 50MPA and maintaining the pressure for more than 15S, gradually reduce the pressure to 0Mpa and then pressurize it 10 times. Experiments have shown that the metal bladder is intact and undamaged after 10 cycles of pressurization, and it can withstand 10 cycles of pressurization.

[0048] The above examples show that the metal capsule can withstand a pressure of 50 MPa and can be pressurized 10 times, thereby achieving lossless separation of strong magnetic materials.

[0049] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
