AI Technical Summary
In existing iron separators, the cooling oil circulates outside the separator, resulting in poor heat dissipation of the internal coils. The heat is transferred to the medium channel, affecting the material state, which is especially harmful to heat-sensitive materials.
The design employs a balanced internal and external cooling system, where cooling oil enters the gaps between the inner and outer shells and is distributed through a separator. The cooling oil in the inner and outer gaps simultaneously acts on the coil, and combined with the inner cooling jacket and spray structure, it achieves all-round cooling of the coil.
This improves the cooling effect of the coil, reduces heat exchange between the coil and the material, and protects the condition of the heat-sensitive material.

Abstract
Description
Technical Field
[0001] This application relates to the field of iron separators, and more particularly to a balanced internal and external cooling iron separator. Background Technology
[0002] Magnetic separators are widely used in production lines of industries such as fine chemicals, lithium batteries, pigments, carbon black, and plastics. During operation, the internal coils of the magnetic separator generate a large amount of heat. Typically, cooling oil circulation is used to dissipate heat from the magnetic separator.
[0003] However, in a typical magnetic separator, the cooling oil circulates outside the separator, which prevents the coil inside the separator from being properly cooled. As a result, the heat emitted by the coil is easily transferred to the medium channel. When the material flowing through the medium channel is sensitive to temperature, it can have a significant impact on the material's condition. Utility Model Content
[0004] In order to improve the heat dissipation effect inside the iron separator and reduce the heat conducted into the medium channel of the iron separator, this application provides a balanced internal and external cooling iron separator.
[0005] The balanced internal and external cooling iron separator provided in this application adopts the following technical solution:
[0006] A balanced internal and external cooling iron separator includes a housing, a medium channel inside the housing, a coil surrounding the medium channel inside the housing, an external gap between the inner wall of the housing and the coil, an external gap between the medium channel and the coil, a cooling inlet at the upper end of one side of the housing, a cooling outlet at the lower end of the other side of the housing, and a separator for connecting to the cooling inlet inside the housing, one end of the separator communicating with the external gap and the other end communicating with the internal gap.
[0007] By adopting the above technical solution, the cooling oil enters the separator in the iron remover through the cooling inlet. Part of the cooling oil enters the outer gap, and the other part enters the inner gap. Thus, the cooling oil plays a cooling role on both sides of the coil at the same time. This balances the cooling effect on both sides of the coil, reduces the heat exchanged between the coil and the material, and thus provides good protection for heat-sensitive materials.
[0008] Optionally, the separator includes an oil reservoir connected to the cooling inlet and located above the coil. The oil reservoir is provided with an oil sprayer that sprays oil towards the upper side of the coil and the outer gap. The oil reservoir is also connected to an oil guide pipe that connects to the inner gap.
[0009] By adopting the above technical solution, external cooling oil enters the oil storage tank through the cooling inlet. Part of the cooling oil is sprayed onto the coil and the outer gap through the oil spraying component, while the other part of the cooling oil enters the inner gap through the oil guide pipe. In this way, the coil and the medium channel can be sufficiently isolated by cooling oil, reducing the heat exchange between the coil and the medium channel, thereby protecting the heat-sensitive materials.
[0010] Optionally, an inner cooling sleeve is provided on the medium channel. The inner cooling sleeve is located above the coil and seals the inner gap. The inner cooling sleeve is hollow inside and connected to the inner gap. The oil guide pipe is connected to the inside of the inner cooling sleeve.
[0011] By adopting the above technical solution, the cooling oil enters the inner cooling jacket through the oil guide pipe, fills the inner cooling jacket, and enters the inner gap through the inner cooling jacket, thereby quickly filling the inner gap and reducing the situation where the other side of the inner gap cannot contact the cooling oil due to only one side entering the inner gap.
[0012] Optionally, the inner cooling jacket has multiple through holes along its circumference, all of which are located above the coil.
[0013] By adopting the above technical solution, after the inner cooling jacket is filled with internal cooling oil, some of the coolant flows out through the through hole and is sprayed onto the top of the coil, thereby cooling the upper side of the coil and improving the cooling effect of the coil.
[0014] Optionally, the fuel injector includes a rotating pipe rotatably connected to the fuel tank, and the end of the rotating pipe away from the fuel tank is provided with multiple branch pipes.
[0015] By adopting the above technical solution, cooling oil is sprayed simultaneously onto the upper side of the coil and into the outer gap through the branch pipe, thereby improving the cooling effect of the coil.
[0016] Optionally, the rotating tube is provided with blades.
[0017] By adopting the above technical solution, during the flow of cooling oil, the cooling oil drives the blades, thereby causing the rotating tube to rotate. The branch pipe rotates with the rotating tube and sprays the cooling oil over a larger area, further improving the coil cooling effect.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] Cooling oil enters the separator in the iron remover through the cooling inlet. Part of the cooling oil enters the outer gap, and the other part enters the inner gap. Thus, the cooling oil cools both sides of the coil simultaneously, resulting in a balanced cooling effect on both sides of the coil. This reduces the heat exchange between the coil and the material, thereby providing good protection for heat-sensitive materials.
[0020] After the inner cooling jacket is filled with internal cooling oil, some of the coolant flows out through the through hole and is sprayed onto the top of the coil, thereby cooling the upper side of the coil and improving the cooling effect of the coil. Attached Figure Description

Detailed Implementation
[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] This application discloses a balanced internal and external cooling iron remover. (Refer to...) Figure 1 and Figure 2 A balanced internal and external cooling iron remover includes a shell 1, a medium channel 2 installed inside the shell 1, a magnetic medium 21 installed inside the medium channel 2, a connecting pipe fixed above the medium channel 2, and a slurry outlet 11, an upper water inlet and an upper iron discharge outlet connected to the connecting pipe, and a slurry inlet 12, a lower water inlet and a lower iron discharge outlet connected below the medium channel 2.
[0026] The housing 1 has a coil 3 installed inside, which surrounds the medium channel 2. There is an outer gap between the inner wall of the housing 1 and the coil 3. There is also an outer gap between the medium channel 2 and the coil 3. A cooling inlet 13 is provided at the upper end of one side of the housing 1, and a cooling outlet 14 is provided at the lower end of the other side of the housing 1. A separator 4 is provided inside the housing 1 for connecting the cooling inlet 13. One end of the separator 4 is connected to the outer gap, and the other end is connected to the inner gap.
[0027] The material enters the medium channel 2 through the inlet 12 and flows out from the outlet 11. At this time, the magnetic medium 21 generates magnetism under the action of the coil 3, and the magnetic substances in the material are adsorbed onto the magnetic medium 21. At this time, the cooling oil enters the separator 4 in the iron remover through the cooling inlet 13. Part of the cooling oil enters the outer gap and the other part enters the inner gap. Thus, the cooling oil plays a cooling role on both sides of the coil 3 at the same time, thereby balancing the cooling effect on both sides of the coil 3 and preventing heat exchange between the coil 3 and the material.
[0028] The separator 4 includes an oil tank 41 that is connected to the cooling inlet 13 and located above the coil 3. The oil tank 41 is fixedly connected to the housing 1. The oil tank 41 is provided with an oil spraying element 43, which sprays cooling oil onto the upper side of the coil 3 and into the outer gap. The oil tank 41 is also connected to an oil guide pipe 42, which connects to the inner gap.
[0029] External cooling oil enters the oil storage tank 41 through the cooling inlet 13. Part of the cooling oil is sprayed onto the coil 3 and the outer gap through the oil sprayer 43, while the other part of the cooling oil enters the inner gap through the oil guide pipe 42. Thus, the coil 3 and the medium channel 2 can be sufficiently isolated by cooling oil, preventing heat exchange between the coil 3 and the material in the medium channel 2.
[0030] An inner cooling sleeve 5 is provided on the upper ring of the medium channel 2. The inner cooling sleeve 5 is located above the coil 3 and blocks the upper end of the inner gap. The inner cooling sleeve 5 is hollow inside, and the lower end of the inner cooling sleeve 5 is open and connected to the inner gap. The oil guide pipe 42 is connected to the temporal part of the inner cooling sleeve 5, thereby connecting the inner gap.
[0031] By adopting the above technical solution, the cooling oil enters the inner cooling jacket 5 through the oil guide pipe 42, fills the inner cooling jacket 5, and enters the inner gap through the inner cooling jacket 5, thereby quickly filling the inner gap and reducing the situation where the other side of the inner gap cannot contact the cooling oil due to only one side entering the inner gap.
[0032] Multiple through holes 51 are provided along the circumference of the inner cooling jacket 5. All through holes 51 are located above the coil 3. After the inner cooling oil fills the inner cooling jacket 5, some of the coolant flows out through the through holes 51 and is sprayed onto the coil 3, thereby cooling the upper side of the coil 3 and realizing all-round cooling and heat dissipation of the coil 3.
[0033] The oil spraying component 43 includes a rotating pipe 431 rotatably connected to the oil reservoir 41. A blade 433 is installed inside the rotating pipe 431, and multiple branch pipes 432 are provided at the end of the rotating pipe 431 away from the oil reservoir 41. During the flow of cooling oil, the cooling oil drives the blades 433, causing the rotating pipe 431 to rotate. The branch pipes 432 rotate with the rotating pipe 431, and the cooling oil is simultaneously sprayed through the branch pipes 432 onto the upper side of the coil 3 and into the outer gap, thereby increasing the cooling oil spray range and improving the cooling effect of the coil 3.
[0034] The implementation principle of a balanced internal and external cooling iron remover in this application embodiment is as follows: Cooling oil enters the oil storage tank 41 through the cooling inlet 13. Part of the cooling oil is sprayed into the outer gap through the rotating pipe 431 and the branch pipe 432, and another part of the cooling oil enters the inner cooling jacket 5 through the oil guide pipe 42 and enters the inner gap to achieve internal and external cooling of the coil 3. At the same time, some cooling oil is sprayed onto the upper side of the coil 3 through the through hole 51 to achieve all-round cooling of the coil 3.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
