Description

Technical Field

[0001] This utility model relates to an oil-circulating cooled electromagnetic separator, belonging to the field of oil-cooled electromagnetic separator technology. Background Technology

[0002] An electromagnetic separator is an electromagnetic device used to remove ferrous parts from bulk, non-magnetic materials. It is typically installed at the head or middle of a belt conveyor. The strong magnetic force generated by energizing the conveyor belt attracts the ferrous parts mixed in with the material, which are then ejected by the unloading belt, achieving automatic removal. This also effectively prevents longitudinal tearing of the conveyor belt, protecting the normal operation of downstream crushers, grinders, and other equipment. Electromagnetic separators are widely used in industries such as power generation, mining, metallurgy, building materials, coal preparation, and chemicals. Based on the cooling method, they can be classified as dry-type electromagnetic separators, air-cooled electromagnetic separators, and oil-cooled electromagnetic separators.

[0003] Commonly used oil-cooled electromagnetic separators are small in size, have high magnetic field strength, and are widely used. However, due to the large amount of coil winding, especially in large electromagnetic separators, the coil diameter increases, the internal cooling effect of the coil is poor, and the coil is prone to burn-out.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing an oil-circulating cooled electromagnetic separator, which allows the cooling oil to flow out sequentially from the inside to the outside, prioritizing internal cooling, preventing localized overheating of the coil, and achieving a better cooling effect.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An oil-circulating cooling electromagnetic separator includes a crossbeam with pulleys at both ends and a separator body between the two pulleys. The separator body includes a cylindrical outer shell and a magnetic suction plate fastened to the lower end of the outer shell. An iron core is coaxially arranged in the middle of the outer shell, and three layers of annular coils are wound around the outside of the iron core. The three layers of coils are arranged at equal intervals in the radial direction.

[0008] The inner coil and the middle coil form a first inner cavity, the middle coil and the outer coil form a second inner cavity, and the outer coil and the inner wall of the outer shell form an outer cavity.

[0009] The upper end and lower end of the first inner cavity are respectively fastened with an upper inner retaining ring and a lower inner retaining ring, and the upper end and lower end of the second inner cavity are respectively fastened with an upper outer retaining ring and a lower outer retaining ring.

[0010] The upper inner retaining ring, the lower inner retaining ring, the upper outer retaining ring, and the lower outer retaining ring all include an annular horizontal plate and an annular vertical plate placed on the outer edge of the horizontal plate. Two annular sealing plates are provided on the side of the horizontal plate facing the coil.

[0011] The upper inner retaining ring horizontal plate is provided with a first water outlet hole, the lower inner retaining ring horizontal plate is provided with a fourth water outlet hole, the lower inner retaining ring vertical plate is provided with a fifth water outlet hole, the lower outer retaining ring horizontal plate is provided with a sixth water outlet hole, the upper outer retaining ring horizontal plate is provided with a second water outlet hole, and the upper outer retaining ring vertical plate is provided with a third water outlet hole.

[0012] The top wall of the outer casing has an upper water inlet located inside the upper inner retaining ring, and the lower end of the side wall of the outer casing has a lower water outlet.

[0013] Furthermore, the first and fourth water outlets are at a 180-degree angle relative to the iron core; the sixth and second water outlets are at a 180-degree angle relative to the iron core.

[0014] Furthermore, multiple annular baffles are provided at equal intervals along the axial direction inside the first inner cavity and the second inner cavity, and a seventh water outlet is provided on the annular baffles.

[0015] Furthermore, the seventh water outlet holes on the two adjacent annular baffles are staggered.

[0016] Furthermore, the inner and outer rings of the annular partition are respectively provided with annular side plates, which extend along the axis to both sides of the annular partition.

[0017] Furthermore, a water pump and a water cooler are provided on the top of the casing. The water pump inlet is connected to the lower outlet, and the water pump outlet is connected to the water cooler.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] Cooling oil enters the inner layer coil from the upper inlet, passing through the first outlet into the upper part of the first inner cavity. The oil then flows out through the fourth outlet on the horizontal plate of the lower inner ring and through the fifth outlet on the vertical plate to the inner side of the space sealed by the lower outer ring. Next, the oil enters the lower part of the second inner cavity through the sixth outlet on the horizontal plate of the lower outer ring, and then flows into the inner side of the space sealed by the upper outer ring through the second outlet on the horizontal plate of the upper outer ring, and through the third outlet on the vertical plate of the upper outer ring to the outer cavity. During the entire cooling oil circulation process, the oil flows sequentially through the first, second, and outer inner cavities, achieving a series connection between the three cavities. This ensures the cooling oil flows evenly across all parts, preventing localized overheating of the coil. Simultaneously, the cooling oil cools from the inside out, prioritizing internal cooling to prevent internal coil burn-out.

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, this utility model provides an oil circulation cooling electromagnetic separator, including a crossbeam 1, with pulleys 2 at both ends of the crossbeam 1, and a separator body between the two pulleys 2. The separator body includes a cylindrical outer shell 4 and a magnetic suction plate 19 fastened to the lower end of the outer shell 4. An iron core 14 is coaxially arranged in the middle position inside the outer shell 4, and three layers of annular coils 13 are wound around the outside of the iron core 14. The three layers of coils 13 are arranged at equal intervals in the radial direction.

[0028] A first inner cavity 6 is formed between the inner coil 13 and the middle coil 13, a second inner cavity 7 is formed between the middle coil 13 and the outer coil 13, and an outer cavity 5 is formed between the outer coil 13 and the inner wall of the outer shell 4.

[0029] The upper end of the first inner cavity 6 is fitted with an upper inner retaining ring 8 and a lower inner retaining ring 10 respectively, and the upper end of the second inner cavity 7 is fitted with an upper outer retaining ring 9 and a lower outer retaining ring 11 respectively.

[0030] like Figure 3 The upper inner retaining ring 8, the lower inner retaining ring 10, the upper outer retaining ring 9 and the lower outer retaining ring 11 all include an annular horizontal plate a1 and an annular vertical plate a2 placed on the outer edge of the horizontal plate. Two annular sealing plates a3 are provided on the side of the horizontal plate a1 facing the coil 13.

[0031] The upper inner retaining ring 8 has a first water outlet hole 801 on the horizontal plate a1, the lower inner retaining ring 10 has a fourth water outlet hole 101 on the horizontal plate a1, the lower inner retaining ring 10 has a fifth water outlet hole 102 on the vertical plate a2, the lower outer retaining ring 11 has a sixth water outlet hole 111 on the horizontal plate a1, the upper outer retaining ring 9 has a second water outlet hole 901 on the horizontal plate a1, and the upper outer retaining ring 9 has a third water outlet hole 902 on the vertical plate a2.

[0032] The top wall of the outer casing 4 is provided with an upper water inlet 18 located inside the upper inner retaining ring 8, and the lower end of the side wall of the outer casing 4 is provided with a lower water outlet 17.

[0033] Cooling oil enters the inner side of the space sealed by the upper inner retaining ring 8 at the top of the inner coil 13 through the upper inlet 18, enters the upper end of the first inner cavity 6 through the first outlet 801, flows out from the fourth outlet 101 on the horizontal plate a1 of the lower inner retaining ring 10, and flows from the fifth outlet 102 on the vertical plate a2 of the lower inner retaining ring 10 to the inner side of the space sealed by the lower outer retaining ring 11. Then, oil enters the lower end of the second inner cavity 7 from the sixth outlet 111 on the horizontal plate a1 of the lower outer retaining ring 11, and enters the inner side of the space sealed by the upper outer retaining ring 9 from the second outlet 901 on the horizontal plate a1 of the upper outer retaining ring 9, and flows to the outer cavity 5 from the third outlet 902 on the vertical plate a2 of the upper outer retaining ring 9. During the entire circulation process of the cooling oil, the cooling oil flows through the first inner cavity 6, the second inner cavity 7 and the outer cavity 5 in sequence, realizing the three cavities in series. This allows the cooling oil to flow evenly through all parts, preventing local overheating of the coil. At the same time, the cooling oil cools from the inside out, allowing the inside of the coil to be cooled first, prioritizing the cooling of the inside, and preventing the problem of internal burn-out of the coil.

[0034] The first water outlet 801 and the fourth water outlet 101 are at a 180-degree angle relative to the iron core 14; the sixth water outlet 111 and the second water outlet 901 are at a 180-degree angle relative to the iron core 14. This relative arrangement of the water outlets allows the cooling oil to flow more evenly through each cavity, resulting in better cooling.

[0035] Multiple annular baffles 12 are provided at equal intervals along their axial direction inside the first inner cavity 6 and the second inner cavity 7. Each annular baffle 12 has a seventh water outlet 122. The annular baffles 12 serve to further equalize the flow of cooling oil.

[0036] The seventh water outlet 122 on the two adjacent annular baffles 12 are staggered.

[0037] Furthermore, such as Figure 4 The annular partition 12 has annular side plates 121 on its inner and outer rings, and the annular side plates 121 extend axially to both sides of the annular partition 12. The annular side plates 121 serve to support the coil 13 on one hand, and fix the two adjacent annular partitions 12 on the other hand.

[0038] The top of the outer casing 4 is equipped with a water pump 16 and a water cooler 15. The water inlet of the water pump 16 is connected to the lower outlet 17, and the water outlet of the water pump 16 is connected to the water cooler 15.
