[0002] In the raw material processing process of ceramics, glass, chemicals, medicine and food, it is usually necessary to use an iron removal device to remove ferromagnetic substances in the raw materials to improve the purity of the raw materials. The magnetic field generated by the electromagnetic coil magnetizes the magnetic medium, making the magnetic medium have a strong magnetic field. When the slurry passes through the magnetic medium, the magnetic substances in the slurry will be adsorbed on the magnetic medium to achieve the purpose of removing ferromagnetic substances in the raw materials.

[0039] The present invention provides a magnetic separator, characterized in that it comprises:

[0040] A barrel 1, wherein the barrel is provided with a cover plate 18;

[0041] A magnetic medium frame 2, wherein the magnetic medium frame 2 can be adaptively placed in the barrel 1;

[0042] Magnetic medium 3, the magnetic medium 3 is mounted in series on the magnetic medium frame 2;

[0043] An upper magnetic pole 9, the upper magnetic pole 9 is disposed above the magnetic medium 3 and connected to the cover plate 18;

[0044] A driving system 4, wherein the driving system 4 is connected to the cover plate 18, and the driving system 4 drives the cover plate 18 to perform linear reciprocating motion, thereby driving the upper magnetic pole 9 to perform linear reciprocating motion;

[0045] A first air inlet pipe 5, which delivers compressed air to the bottom of the barrel 1;

[0046] A second air intake pipe 6 , which delivers compressed air from the upper part of the barrel 1 downwards.

[0047] In the present invention, during the cleaning operation, the driving system 4 drives the cover plate 18 to make a linear reciprocating motion, thereby driving the upper magnetic pole 9 to make a linear reciprocating motion. After the pressure on the magnetic medium 3 by the upper magnetic pole 9 disappears, the magnetic medium 3 is naturally fluffy due to its own elasticity, and at the same time, it also provides power for the separation of the magnetic substance and the magnetic medium 3, so that the magnetic substance is separated from the magnetic medium 3, and also provides space and power for clean water to enter the barrel 1, so that the clean water can clean the magnetic medium 3; at the same time, the first air inlet pipe 5 transports compressed air to the bottom of the barrel 1 At this time, the barrel 1 is filled with clean water, and the compressed air is discharged from the bottom to the top of the barrel 1 through the first air inlet pipe 5, passing through the magnetic medium 3 to separate a large number of small bubbles, and the magnetic material adsorbed on the surface of the magnetic medium 3 is separated from the magnetic medium 3 by the combined force of the small bubbles and the driving system 4, and the compressed air is finally discharged from the top of the barrel 1; then the first air inlet pipe 5 stops delivering compressed air, and the second air inlet pipe 6 is opened and delivers compressed air into the barrel 1, and the magnetic material is quickly discharged along with the sewage, thereby achieving high-quality and efficient cleaning effects.

[0048] It should be noted that the technical solution proposed in the present invention is applicable to both horizontal magnetic separators and vertical magnetic separators, and is not limited to the embodiments provided in the present invention.

[0049] Specifically, the driving system 4 includes a driving end 41 and a telescopic end 42 . The telescopic end 42 is connected to the cover plate 18 . The driving end 41 drives the telescopic end 42 to perform linear reciprocating motion, thereby driving the upper magnetic pole 9 to perform linear reciprocating motion.

[0050] When the driving system 4 is not working, the upper magnetic pole 9 is stationary, and this position is defined as the original position. When the telescopic end 42 is extended, the upper magnetic pole 9 is away from the original position. When the telescopic end 42 is retracted, the upper magnetic pole 9 is close to the original position to realize the linear reciprocating motion of the upper magnetic pole 9. When the upper magnetic pole 9 is in the original position, the magnetic medium 3 is in a compressed state. When the upper magnetic pole 9 is away from the original position, the magnetic medium 3 stretches and returns to its original state, thereby obtaining natural fluffiness, so that the magnetic material adsorbed on the magnetic medium falls off. In this way, during the cleaning operation, the barrel 1 is filled with clean water. Since the upper magnetic pole 9 continuously reciprocates up and down, the magnetic medium 3 is continuously stretched and compressed. The magnetic material is separated from the magnetic medium 3 under the action of the elastic restoring force of the magnetic medium 3 and the continuous collision of clean water, so as to achieve the purpose of separating the magnetic material from the magnetic medium 3, thereby improving the cleaning quality.

[0051] It should be noted that the driving system 4 can be a motor, a cylinder or a hydraulic cylinder, which is not limited here. Preferably, the hydraulic cylinder is used in this embodiment.

[0052] Specifically, the first air intake duct 5 includes an air intake main pipe 51 and an air intake branch pipe 52. The air intake main pipe 51 is connected to the top of the serial tube 21 of the magnetic medium rack 2 through a steam nozzle 7, and the air intake branch pipe 52 is connected to the bottom of the serial tube 21 through a steam nozzle 7.

[0053] A circular through hole is provided on the top of the serial tube 21 of the magnetic medium frame 2, and the steam nozzle 7 is plugged into the circular through hole. The air intake main pipe 51 is mounted on the steam nozzle 7. A plurality of circular through holes are distributed in annular patterns at intervals on the bottom of the serial tube 21, and the steam nozzle 7 is plugged into the circular through holes. The air intake branch pipe 52 is mounted on the steam nozzle 7. The compressed air enters the serial tube 21 from the air intake main pipe 51, and is then output from the air intake branch pipe 52 connected to the bottom of the serial tube 21. The air intake branch pipe 52 distributed in annular patterns at intervals on the bottom of the serial tube 21 ensures that the magnetic medium 3 can be radiated by compressed air in all directions, so that the magnetic medium 3 is thoroughly cleaned. Therefore, the iron removal effect will not be affected by the magnetic substances remaining on the magnetic medium 3 each time the iron is removed, thereby ensuring an excellent iron removal effect.

[0054] During the cleaning operation, clean water is poured into the barrel 1, and at the same time, the first air intake pipe 5 inputs compressed air into the barrel 1. The compressed air enters from the air intake main pipe 51, passes through the series pipe 21, and is output from the air intake branch pipe 52. The compressed air flows upward from the bottom of the barrel 1. When the compressed air passes through the magnetic medium 3, it is broken into a large number of small bubbles. A large number of small bubbles flow upward irregularly in the magnetic medium 3. At this time, the magnetic material adsorbed on the magnetic medium 3 is either wrapped or collided and taken away from the magnetic medium 3, thereby being dispersed into the flowing clean water.

[0055] The path of compressed air entering the first air intake passage is as follows: the compressed air enters from the air intake main pipe 51 , then enters the air intake branch pipe 52 through the series pipe 21 , and finally is output from the air gap 521 of the air intake branch pipe 52 .

[0056] Furthermore, the air intake branch pipe 52 is provided with an air gap 521, and the air intake branch pipe 52 is in a filled state when compressed air is input, and the air gap 521 is in an expanded state when compressed air is input; the air intake branch pipe 52 is in a contracted state when the compressed air input stops, and the air gap 521 is in a closed state when the compressed air input stops.

[0057] Furthermore, the air intake branch pipe 52 is an elastic hose. When the compressed air is stopped from being delivered to the air intake branch pipe 52, the air intake branch pipe 52 is in an elastic contraction state, and the air gap 521 is in a closed state. At this time, the second air intake pipe 6 delivers compressed air to the barrel 1, and the magnetic material is discharged wrapped in clean water. Since the air gap 521 of the air intake branch pipe 52 is in a closed state, sewage and magnetic material cannot enter the air intake branch pipe 52, so that the air intake branch pipe 52 is well protected and avoids frequent replacement of the air intake branch pipe 52. In addition, when replacing the air intake branch pipe 52, it is necessary to stop the machine for replacement, which will affect the production progress.

[0058] Specifically, the barrel 1 is provided with a main pipe 8 , the main pipe 8 is communicated with the serial pipe 21 , and the second air intake pipe 6 is communicated with the barrel 1 through the main pipe 8 .

[0059] Furthermore, the main pipe 8 passes through the top of the barrel 1, so that the cover plate 18 fixes the main pipe, and the main pipe 8 is mounted on the upper part of the series pipe 21, and a cavity is provided between the inner wall of the main pipe 8 and the series pipe 21. During the iron removal operation, the non-magnetic material enters the main pipe 8 from the cavity and is then output. The provision of the cavity can ensure the output of the non-magnetic material. Since the second air intake pipe 6 is connected to the main pipe 8, the compressed air passes through the second air intake pipe 6 and then is transported to the barrel 1 via the main pipe 8, and is discharged from the top to the bottom of the barrel 1.

[0060] During the cleaning operation, when the first air inlet pipe 5 is closed, the second air inlet pipe 6 is opened to deliver compressed air into the barrel 1. A large amount of compressed air enters the barrel 1, so that the sewage in the barrel 1 can be quickly discharged, further improving the cleaning effect of the magnetic medium 3 and ensuring that the iron removal effect is not affected.

[0061] Specifically, the upper end of the main pipe 8 is connected with a water inlet 812 , an air outlet 813 and a material outlet 814 , and the lower end of the main pipe 8 is connected with a material inlet 821 and a sewage outlet 822 .

[0062] In this embodiment, a bottom-in-top-out slurry feeding method is adopted, the slurry enters from the feed port 821 at the bottom end of the main pipe 8, and the slurry after iron removal is output from the discharge port 814 at the upper end of the main pipe 8; the exhaust port 813 is used to discharge the compressed air of the first air intake pipe 5, the water inlet 812 is used to transport clean water during cleaning operations, and the sewage outlet 822 is used to discharge sewage and magnetic substances after cleaning operations.

[0063] Furthermore, the main pipe 8 includes a first main pipe 81 and a second main pipe 82, the bottom of the first main pipe 81 is connected to the top of the series pipe 21, the top of the second main pipe 82 is connected to the center of the bottom of the magnetic medium frame 2, the bottom of the first main pipe 81 is narrowed, and the first main pipe 81 is connected to a plurality of first branch pipes 811.

[0064] The headquarters is provided with a plurality of the first branch pipes 811 in a ring shape, and the first main pipe 81 adopts a structure that is wide at the top and narrow at the bottom. When high-pressure clean water comes in, the clean water is reasonably dispersed, and the magnetic medium 3 is evenly rinsed, so that the magnetic medium 3 is thoroughly cleaned. Therefore, each time the iron is removed, the iron removal effect will not be affected by the magnetic material remaining on the magnetic medium 3, thereby ensuring an excellent iron removal effect.

[0065] During the iron removal operation, the slurry enters from the cavity of the first main pipe 81 and the first branch pipe 811 respectively, then converges at the main pipe 8, and finally is output from the discharge port 814. The provision of several first branch pipes 811 is conducive to speeding up the output of the slurry and achieving the purpose of improving work efficiency.

[0066] Specifically, the magnetic separator also includes:

[0067] A lower magnetic pole 10, wherein the lower magnetic pole 10 is arranged below the magnetic medium frame 2;

[0068] An electromagnetic coil 11, wherein the electromagnetic coil 11 is arranged around the barrel 1;

[0069] A shielding box 12, wherein the electromagnetic coil 11 is placed in the shielding box 12, the barrel 1 is arranged to pass through the shielding box 12, and an oil chamber 121 is arranged in the shielding box 12, and the oil chamber 121 is filled with insulating oil;

[0070] A frame 13, on which the shielding box 12 is placed;

[0071] A heat exchanger 14, wherein the heat exchanger 14 is mounted on the frame 13;

[0072] An oil pump 15, wherein the oil pump 15 is installed on the frame 13 and is located at one side of the heat exchanger 14;

[0073] The oil pump 15 , the shielding box 12 and the heat exchanger 14 are connected with oil pipes 16 .

[0074] Specifically, the heat generated by the electromagnetic coil 11 is conducted to the insulating oil in the shielding box 12, and the oil pump 15 extracts the high-temperature insulating oil from the shielding box 12 and transports it to the heat exchanger 14 for heat exchange, so that the temperature of the insulating oil drops, and then the cooled insulating oil is transported to the top of the coil through the oil pipe 16, and this cycle is continuously carried out to achieve effective cooling and ensure the continuous operation of the magnetic separator; preferably, the heat exchanger 14 used in this embodiment is a plate heat exchanger, which has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger 14, and the footprint is one-third of the tubular heat exchanger 14, and the heat recovery rate can be as high as 90% or more.

[0075] Working principle of iron removal operation: electromagnetic coil 11 is energized, upper magnetic pole 9 and lower magnetic pole 10 are magnetized, magnetic medium 3 generates high magnetic field gradient, slurry enters barrel 1 from feed port 821 at the lower end of main pipe 8, slurry passes through magnetic medium 3, magnetic material in slurry is adsorbed on magnetic medium 3, slurry after magnetic material is removed is output from discharge port 814 at the top end of main pipe 8, and magnetic separation is completed.

[0076] The working principle of the cleaning operation: the electromagnetic coil 11 stops being energized, the magnetic medium 3 does not generate a high magnetic field gradient, the magnetic material is not constrained by magnetic force, and clean water enters the barrel 1 from the water inlet 812 at the upper end of the main pipe 8. The drive system 4 drives the upper magnetic pole 9 to perform linear reciprocating motion, so that the mesh structure of the magnetic medium 3 becomes fluffy, and also provides power for the separation of the magnetic medium 3 from the magnetic material. The air intake main pipe 51 transports the compressed air to the bottom of the magnetic medium frame 2, and transports it to the bottom of the barrel 1 and the magnetic medium 3 through a plurality of air intake branches 52. Since the air intake branch 52 is provided with a plurality of air gaps 521, the compressed air is evenly distributed at the bottom of the barrel 1 and the magnetic medium 3. When the compressed air moves upward The compressed air is discharged from the exhaust port 813 at the top of the main pipe 8 after being converged by the first branch pipe 811 and the first main pipe 81; then the air intake main pipe 51 is closed to stop delivering compressed air, the second air intake pipe 6 is opened and compressed air is delivered into the barrel 1; since the air intake main pipe 51 is closed, the air intake branch pipe 52 undergoes elastic contraction, the air gap 521 is closed, and impurities do not enter the air intake branch pipe 52; the compressed air is transported from top to bottom and pushes the sewage to the sewage outlet 822 at the lower end of the main pipe 8 for discharge, thus completing the cleaning work.

[0077] Specifically, the shielding box 12 is also equipped with an oil pillow 17, and a liquid level sensor is arranged inside the oil pillow 17.

[0078] Since the insulating oil in the shielding box 12 expands upward after being heated, an oil pillow 17 is provided at a high position of the magnetic separator. A liquid level sensor is provided in the oil pillow 17. The liquid level sensor detects the height of the insulating oil in the shielding box 12 in real time, providing reliable protection for the operation of the magnet.

[0079] Preferably, a temperature sensor is disposed inside the electromagnetic coil 11 .

[0080] The electromagnetic coil 11 is provided with a temperature sensor inside to effectively prevent the temperature from being too high, thus providing reliable protection for the operation of the whole machine.
