The possible agglomerates in the steel slag are pre-processed by the rolling mechanism, which effectively ensures that the material can be evenly transported to the upper surface of the air distribution plate. The air distribution plate is inclined and under the action of vibration, it cooperates with the air flow ejected from the wind hood, which can make the steel slag quickly present fluidization and stratification effects, thereby effectively improving the separation efficiency of the steel slag. At the same time, it avoids the agglomeration of mineral particles generated when the steel slag is separated by a strong magnetic field, reduces the time consumed in the separation of the steel slag, and further improves the separation efficiency of the steel slag.

[0033] In the relevant technology, with the advancement of science and technology, the sorting particle size of steel slag has been refined from millimeter level to micron level, and the sorting mode has also expanded from wet to dry. Although wet magnetic separation performs well in terms of sorting efficiency, it also has certain limitations. In contrast, dry magnetic separation has significant advantages such as low investment cost, low operating cost, environmental protection and energy saving. In the magnetic separation of ore in some resource-rich but water-scarce areas, the advantages of dry magnetic separation are particularly prominent, which effectively makes up for the shortcomings of wet magnetic separation. Especially when dealing with materials containing hydration-active components (such as steel slag), dry magnetic separation is indispensable. Dry magnetic separation can not only avoid the adverse effects of hydration and cementation of hydration-active components on the sorting process, but also help to enrich and protect the hydration-active components from destruction. However, the RO phase in steel slag is a co-solvent of FeO, MgO, and MnO. Under a strong magnetic field environment, the RO phase will undergo magnetic agglomeration and electrostatic adsorption with other unnecessary mineral particles, thereby forming agglomerates. The existing dry magnetic separation equipment cannot properly separate the unnecessary mineral particles. In order to achieve a better separation effect, multiple magnetic separation operations are often required, which affects the separation efficiency of the steel slag.

[0034] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a steel slag magnetic separation device.

[0035] like Figures 1 to 5 As shown, a steel slag magnetic separation device provided by an embodiment of the present invention includes a magnetic separation device shell 1, an air distribution plate 2, a compressor 3, a pneumatic vibration mechanism 4, a rolling mechanism 5 and a chute 6, wherein the air distribution plate 2 is arranged inside the magnetic separation device shell 1 in an upward tilt along a first direction, and the end of the air distribution plate 2 away from the bottom of the magnetic separation device is in contact with the rolling mechanism 5, and a chute 6 is arranged below the end of the air distribution plate 2 close to the bottom of the magnetic separation device shell 1, and the air distribution plate 2 is slidably connected to the bottom of the magnetic separation device shell 1 along a second direction, and a pneumatic vibration mechanism 4 is arranged at the bottom of the magnetic separation device shell 1, and the pneumatic vibration mechanism 4 is connected to the air distribution plate 2. The air distribution plate 2 is connected, the pneumatic vibration mechanism 4 is used to drive the air distribution plate 2 to vibrate along the second direction, the compressor 3 is arranged below the housing 1 of the magnetic separation equipment, the air outlet pipe 31 of the compressor 3 is connected to the air inlet of the pneumatic vibration mechanism 4, the air outlet of the pneumatic vibration mechanism 4 is connected to the air distribution plate air inlet 27 on the lower surface of the air distribution plate 2, a plurality of wind hoods 21 are arranged on the upper surface of the air distribution plate 2, the wind hoods 21 are connected to the air distribution plate air inlet 27, the air intake pipe 32 of the compressor 3 is connected to the air intake port opened above the housing 1 of the magnetic separation equipment, and the first direction, the second direction and the vertical direction are perpendicular to each other.

[0036] Specifically, the housing 1 of the magnetic separation equipment serves as the outer shell of the slag magnetic separation equipment, and plays the role of supporting and protecting the internal components. The housing 1 includes components such as an air distribution plate 2, a pneumatic vibration mechanism 4, and a rolling mechanism 5, and provides a closed space environment for the magnetic separation process of the material. The air distribution plate 2 is placed obliquely in the housing 1 of the magnetic separation equipment. The oblique setting is conducive to the movement of the slag in a specific direction under the action of vibration and airflow, that is, from the relatively high end of the air distribution plate 2 to the relatively low end. The end of the air distribution plate 2 away from the bottom of the housing 1 of the magnetic separation equipment contacts the rolling mechanism 5, that is, the relatively high end of the air distribution plate 2 contacts the rolling mechanism 5. When the slag enters the rolling mechanism 5 and is rolled, it is introduced to the upper side of the relatively high end of the air distribution plate 2. Thus, through the vibration of the air distribution plate 2 and the airflow of the hood 21, when the speed at which the slag material particles are suspended in the upward flowing gas is reached, the slag material particles present a fluid-like property, realize fluidization, and promote the slag to flow to the chute 6 at the other end, which is convenient for the discharge of the material after magnetic separation. The rolling mechanism 5 is arranged at the bottom of the magnetic separation equipment housing 1, and the upper end of the rolling mechanism 5 can be connected to the feed port 8. When the steel slag enters from the feed port 8, the steel slag is rolled by the rolling mechanism 5, so that the steel slag agglomerated due to moisture and other factors can be crushed to prevent the agglomeration of the steel slag from affecting the fluidization and magnetic separation efficiency, and ensure that the material can smoothly perform subsequent fluidization and magnetic separation operations on the air distribution plate 2. The air distribution plate 2 is inclined upward along the first direction to form an acute angle with the first direction. The first direction can be the length direction of the magnetic separation equipment housing 1, and the second direction can be the width direction of the magnetic separation equipment housing 2.

[0037] In addition, the air distribution plate 2 is slidably connected to the bottom of the magnetic separation equipment housing 1 to ensure that it can stably vibrate laterally under the action of the pneumatic vibration mechanism 4, thereby realizing the fluidization and separation operation of the steel slag. The compressor 3 is located below the magnetic separation equipment housing 1, providing airflow power for the magnetic separation equipment. The compressor 3 is connected to the air intake port above the magnetic separation equipment housing 1 through the suction pipe 32. During the operation of the equipment, the dust-containing gas generated by vibration and fluidization in the housing can be sucked in. After subsequent treatment, it can prevent dust from polluting the environment and avoid material loss. In addition, a filter element is provided in the suction pipe 32 to effectively filter out the inhaled dust and impurities. At the same time, the air outlet pipe 31 of the compressor 3 is connected to the air inlet of the pneumatic vibration mechanism 4, providing compressed gas for the pneumatic vibration mechanism 4 to drive it to work. The pneumatic vibration mechanism 4 uses the compressed gas provided by the compressor 3 to generate power to drive the air distribution plate 2 to vibrate horizontally (i.e., along the second direction). Through the vibration, the steel slag material on the air distribution plate 2 is caused to have gaps and loose layers, creating conditions for subsequent fluidization and magnetic separation. In addition, the air outlet of the pneumatic vibration mechanism 4 is connected to the air distribution plate air inlet 27 on the lower surface of the air distribution plate 2, so that part of the gas is transported to the air distribution plate 2, so that the gas The body is sprayed out through the wind hood 21 on the upper surface of the air distribution plate 2, thereby causing the steel slag located on the upper surface of the air distribution plate 2 to fluidize, wherein, the lower surface of the air distribution plate 2 is provided with an air distribution plate air inlet 27, and the upper surface of the air distribution plate 2 is provided with a wind hood 21 with multiple air outlets, and multiple air flow channels are provided inside the air distribution plate 2, one end of each air flow channel is connected to the air distribution plate air inlet 27, and the other end is respectively connected to each wind hood 21, so that the compressed air provided by the compressor 3 is distributed to each wind hood 21 through the air inlet, and thus blown out through the wind hood 21.

[0038] In this embodiment, the air distribution plate 2 is tilted and can vibrate laterally under the drive of the pneumatic vibration mechanism 4, so that the steel slag material can be quickly loosened, layered and fluidized on the air distribution plate 2. The tilt angle is conducive to the orderly movement of the steel slag toward the chute 6 under the action of vibration and airflow, and the gaps between the materials are generated by vibration to prevent agglomeration and accumulation, which can improve the uniformity and smoothness of the materials entering the magnetic separation area, thereby improving the magnetic separation efficiency. Through the air path connection design of the compressor 3, the pneumatic vibration mechanism 4 and the air distribution plate 2, while providing sufficient power for the pneumatic vibration mechanism 4, it also ensures a stable airflow supply to the air distribution plate 2. After the gas output from the compressor 3 drives the air distribution plate 2 to vibrate through the pneumatic vibration mechanism 4, part of the gas enters the air distribution plate air inlet 27 of the air distribution plate 2, providing continuous power for the fluidization of the steel slag, so that the steel slag is always in a good fluidized state, which is conducive to the separation of magnetic and non-magnetic materials. One end of the air distribution plate 2 is in contact with the rolling mechanism 5, which can roll the slag when it enters. For wet or easily agglomerated slag materials, the rolling operation can effectively break up the agglomerates, avoid the problems of poor fluidization and poor magnetic separation caused by agglomeration, and ensure that the slag can be smoothly processed in the subsequent process. The suction pipe 32 of the compressor 3 is connected to the suction port above the housing 1 of the magnetic separation equipment, so as to timely absorb the dust generated by the vibration and fluidization of the slag inside the equipment. On the one hand, it prevents the dust from accumulating in the equipment and affecting the operation of the magnetic separation equipment and the slag processing effect. On the other hand, it prevents the dust from being discharged into the environment to cause pollution, protects the working environment and the health of the operators, and reduces material losses. The possible agglomerates in the steel slag are pre-processed by the rolling mechanism 5, which effectively ensures that the material can be evenly transported to the upper surface of the air distribution plate 2. The air distribution plate 2 is inclined and under the action of vibration, it cooperates with the air flow ejected from the wind hood 21, so that the steel slag can quickly present a fluidization and stratification effect, thereby effectively improving the separation efficiency of the steel slag, and at the same time avoiding the agglomeration of mineral particles generated when the steel slag is separated by a strong magnetic field, reducing the time consumed in the separation of the steel slag, and further improving the separation efficiency of the steel slag.

[0039] Alternatively, if Figure 1 and 4 As shown, the rolling mechanism 5 includes a fixed part 51 and a movable part 52, the lower end of the fixed part 51 is arranged on the bottom of the magnetic separation equipment housing 1, the fixed part 51 is in contact with one end of the air distribution plate 2 away from the bottom of the magnetic separation equipment housing 1, the upper end of the fixed part 51 is provided with a rolling groove, the movable part 52 is arranged in the rolling groove, the outer wall of the movable part 52 and the inner wall of the rolling groove constitute a rolling channel, the feed end of the rolling channel is used to communicate with the feed port 8, and the discharge end of the rolling channel is arranged above the air distribution plate 2.

[0040] Specifically, the rolling mechanism 5 includes a fixed part 51 and a moving part 52. The fixed part 51 is arranged at the bottom of the housing 1 of the magnetic separation device. The fixed part 51 is in close contact with the end of the air distribution plate 2 away from the bottom of the device, that is, in close contact with the relatively higher end of the inclined air distribution plate 2, so that the steel slag flowing out of the rolling mechanism 5 can accurately fall onto the air distribution plate 2. A rolling groove is arranged at the upper end of the fixed part 51. The opening of the rolling groove faces the vertical direction on one side and faces the direction where the air distribution plate 2 is located on the other side. Its shape and size match the moving block. After the moving part 52 is arranged in the rolling groove, there is a gap between the moving part 52 and the fixed part 51, thereby forming a rolling channel, so that the steel slag can be guided to be rolled in an orderly manner. For example, the inner wall of the rolling groove can have a certain inclination angle or special texture, which helps the material to move smoothly to the discharge end when being squeezed, and also increases the friction between the material and the moving part 52 and the inner wall of the rolling groove, thereby improving the rolling effect. The feed port 8 is connected to the feed end of the rolling channel, so that the material can smoothly enter the rolling mechanism 5. After the joint rolling action of the moving part 52 and the fixed part 51, the material is discharged from the discharge end of the rolling channel and accurately falls on the air distribution plate 2 located below.

[0041] In this optional embodiment, the rolling mechanism 5 ensures that the steel slag can directly enter the subsequent fluidization and magnetic separation process after pretreatment, thereby achieving the continuity and efficiency of the material handling process inside the entire equipment, thereby improving the separation efficiency of the steel slag.

[0042] Alternatively, if Figures 6 to 8 As shown, a connecting rod 53 is provided on one side of the movable portion 52 close to the air distribution plate 2, and the connecting rod 53 extends outward along the second direction and passes through the magnetic separation equipment housing 1, and fixed rods 22 are symmetrically provided on both sides of the second direction at one end of the air distribution plate 2 close to the fixed portion 51, and the fixed rods 22 extend outward along the second direction, pass through the magnetic separation equipment housing 1, and are connected to the connecting rod 53.

[0043] In this optional embodiment, a connecting rod 53 is provided on one side of the movable part 52 close to the air distribution plate 2, and the connecting rod 53 extends horizontally from both ends to the outside of the magnetic separation equipment housing 1. Fixed rods 22 are symmetrically provided on both sides of one end of the air distribution plate 2 close to the fixed part 51, and the fixed rods 22 also extend to the outside of the magnetic separation equipment housing 1. One end of the fixed plate extending out of the outside of the magnetic separation equipment housing 1 is connected to one end of the connecting rod 53 extending out of the outer shell of the magnetic separation equipment on the corresponding side, thereby realizing the connection between the air distribution plate 2 and the movable part 52 of the rolling mechanism 5. When the air distribution plate 2 generates lateral vibration under the action of the pneumatic vibration mechanism 4, the vibration will be transmitted to the connecting rod 53 through the fixed rod 22, and then the movable part 52 will be driven to vibrate laterally together through the connecting rod 53, so that the lateral vibration of the movable part 52 can be used to roll the steel slag in the rolling trough, and the steel slag agglomerated due to factors such as moisture can be crushed to prevent the agglomeration of steel slag from affecting fluidization and magnetic separation, thereby improving the separation efficiency of the steel slag.

[0044] Alternatively, if Figures 6 to 8 As shown, the slag magnetic separation equipment also includes a connecting mechanism 28, which includes a pull rod 281, a fixing ring 282 and a nut 283. The fixing rod 22 extends out of the magnetic separation equipment housing 1 and is provided with a first through hole at one end thereof. One end of the pull rod 281 passes through the first through hole and is connected to the fixing rod 22 via the fixing ring 282. The connecting rod 53 extends out of the magnetic separation equipment housing 1 and is provided with a second through hole at one end thereof. The other end of the pull rod 281 is provided with a thread. The other end of the pull rod 281 passes through the second through hole and is threadedly connected to the nut 283.

[0045] In this optional embodiment, a first through hole is provided at one end of the fixed rod 22 extending out of the housing 1 of the magnetic separation device, and one end of the pull rod 281 passes through the first through hole and cooperates with the fixing ring 282, and is then connected to the fixed rod 22. The fixing ring 282 serves to limit the position of the pull rod 281 and enhance the stability of the connection, thereby preventing the pull rod 281 from unnecessary displacement or shaking during the operation of the device. A second through hole is provided at one end of the connecting rod 53 extending out of the housing 1 of the magnetic separation device, which is used to accommodate the other end of the pull rod 281. The other end of the pull rod 281 is provided with a thread, and the other end of the pull rod 281 passes through the second through hole and is threadedly connected with the nut 283. Tightening the nut 283 can further strengthen the connection between the pull rod 281, the connecting rod 53 and the fixed rod 22, making it a stable integral structure, thereby realizing a reliable mechanical connection between the fixed rod 22 and the connecting rod 53, and facilitating installation, disassembly and maintenance. When the air distribution plate 2 vibrates laterally, the link structure can drive the moving part 52 to vibrate laterally together, thereby rolling the steel slag in the rolling trough, thereby improving the separation efficiency of the steel slag.

[0046] Alternatively, if Figure 1 , 3 As shown in 7, a first support column 23 is provided on the bottom surface of one end of the air distribution plate 2 close to the rolling mechanism 5, and a second support column 24 is provided on the bottom surface of the end of the air distribution plate 2 away from the rolling mechanism 5, the height of the first support column 23 is greater than the height of the second support column 24, and the lower ends of the first support column 23 and the second support column 24 are respectively provided with grooves extending along the second direction, and the air distribution plate 2 is slidably connected to the first slider 16 and the second slider 16 provided at the bottom of the magnetic separation equipment housing 1 through the grooves at the lower ends of the first support column 23 and the second support column 24, respectively, wherein the axial direction of the groove is perpendicular to the length direction of the air distribution plate 2.

[0047] In this optional embodiment, the air distribution plate 2 is provided with a first support column 23 on the bottom surface of one end close to the rolling mechanism 5, and a second support column 24 on the bottom surface of one end away from the rolling mechanism 5, wherein the height of the first support column 23 is greater than the height of the second support column 24, so that the air distribution plate 2 can be provided in an inclined state, and the inclined air distribution plate 2 is conducive to the steel slag moving in a specific inclined direction on the air distribution plate 2 under the action of vibration and airflow. Grooves are provided at the lower ends of the first support column 23 and the second support column 24, respectively, and a first slider 16 and a second slider 16 are correspondingly provided at the bottom of the magnetic separation device housing 1, and the air distribution plate 2 is slidably connected with the slider 16 through these grooves, and the axial direction of the groove is perpendicular to the length direction of the air distribution plate 2, and the length direction of the air distribution plate 2 is along the first support column 23 pointing to the second support column 24, so that the air distribution plate 2 can achieve lateral vibration through the cooperation of the groove and the slider 16, that is, the air distribution plate 2 can smoothly perform lateral vibration when driven by the pneumatic vibration mechanism 4. For example, when the pneumatic vibration mechanism 4 is working, the air distribution plate 2 can rely on the cooperation between the groove and the slider 16 to move back and forth smoothly in the horizontal direction, thereby effectively loosening, stratifying and fluidizing the slag material. At the same time, the groove design perpendicular to the length direction of the air distribution plate 2 limits the unnecessary displacement of the air distribution plate 2 in other directions, further enhancing the stability and reliability of the equipment operation, and helping to improve the separation efficiency and quality of the slag material. Figure 6 As shown, the direction of the arrow X is the second direction.

[0048] Alternatively, if Figures 3 to 7As shown, the bottom surface of the air distribution plate 2 is provided with a first wear-resistant plate 25 and a second wear-resistant plate 26 at intervals along the second direction, the pneumatic vibration mechanism 4 includes a pneumatic vibration mechanism 4 shell, an eccentric cam 42, a fan 43 and a volute 44, the fan 43 and the volute 44 are arranged inside the shell of the pneumatic vibration mechanism 4, the air inlet of the volute 44 is connected to the air outlet of the compressor 3, the fan 43 is arranged at the air outlet of the volute 44, the air outlet of the volute 44 is connected to the air distribution plate air inlet 27 on the lower surface of the air distribution plate 2, the fan 43 is coaxially connected to the eccentric cam 42 through a connecting shaft extending out of the shell of the pneumatic vibration mechanism 4, the eccentric cam 42 is arranged between the first wear-resistant plate 25 and the second wear-resistant plate 26, and the eccentric cam 42 is constructed to drive the first wear-resistant plate 25 and the second wear-resistant plate 26 to reciprocate along the second direction when the fan 43 rotates.

[0049] In this optional embodiment, the bottom surface of the air distribution plate 2 is provided with a first wear-resistant plate 25 and a second wear-resistant plate 26 at intervals along the axial direction of the groove, and its main function is to withstand the force generated by the pneumatic vibration mechanism 4, wherein the first wear-resistant plate 25 and the second wear-resistant plate 26 are provided between the first support column 23 and the second support column 24. A fan 43 and a volute 44 are provided in the shell of the pneumatic vibration mechanism 4. The airflow output by the compressor 3 enters from the air inlet of the volute 44, and after the flow-guiding effect of the volute 44, it is blown out from the air outlet, driving the fan 43 located at the air outlet to rotate. The fan 43 is coaxially connected to the eccentric cam 42 through a connecting shaft. When the fan 43 rotates, the eccentric cam 42 is driven to rotate accordingly through the connecting shaft. The eccentric cam 42 is located between the first wear-resistant plate 25 and the second wear-resistant plate 26. Its special shape and motion trajectory enable it to alternately push the first wear-resistant plate 25 and the second wear-resistant plate 26 during the rotation process, thereby driving the air distribution plate 2 to achieve lateral vibration. Through the lateral vibration, the slag material on the air distribution plate 2 can have gaps and loosen the layers, thereby improving the separation efficiency of the slag. At the same time, by adjusting the speed of the fan 43 or the air flow parameters of the volute 44, the rotation speed and strength of the eccentric cam 42 can be controlled, and then the vibration frequency and amplitude of the air distribution plate 2 can be adjusted to adapt to slag materials of different properties and states, and improve the flexibility and processing efficiency of slag separation.

[0050] Specifically, Figure 8As shown, the X direction is the second direction, that is, the width direction of the air distribution plate 2, and the C direction is the clockwise rotation direction of the eccentric cam 42, wherein the solid line is the current eccentric cam 42 abutting against the first wear-resistant plate 25 on the left. When the eccentric cam 42 rotates clockwise along the direction of C, it gradually approaches the second wear-resistant plate 26 and pushes the second wear-resistant plate 26 to move right along the direction of X. With the clockwise circular motion of the eccentric cam 42, the air distribution plate 2 connected to the first wear-resistant plate 25 and the second wear-resistant plate 26 is pushed respectively along the second direction.

[0051] Alternatively, if Figure 1 and 2 As shown, the steel slag magnetic separation equipment also includes a recovery mechanism 9, which includes a drum 91, a scraper 92, a fixed arc plate 93 and a magnetic block 94. The drum 91 is arranged between the air distribution plate 2 and the chute 6. The scraper 92 is connected to the shell of the magnetic separation equipment and abuts against the outer wall of the drum 91. A fixed arc plate 93 is arranged inside the drum 91. A magnetic block 94 is arranged on the side of the fixed arc plate 93 close to the inner wall of the drum 91. A hollow opening is opened on the chute 6, and the position of the hollow opening matches the position of the drum 91.

[0052] In this optional embodiment, the drum 91 is arranged between the air distribution plate 2 and the chute 6. When the steel slag material fluidized and vibrated and layered by the air distribution plate 2 moves to the vicinity of the drum 91 along the inclined air distribution plate 2, the steel slag can be further screened and separated by the drum 91. A fixed arc plate 93 is arranged inside the drum 91, and a plurality of magnetic blocks 94 are evenly arranged on the side of the fixed arc plate 93 close to the inner wall of the drum 91. The magnetic blocks 94 located between the drum 91 and the arc plate have strong magnetism. During the magnetic separation process, the magnetic steel slag particles will be attracted by the magnetic blocks 94 and attached to the outer wall of the drum 91, while the non-magnetic materials will continue to move to the chute 6 under the rotation of the drum 91 and the gravity of the materials themselves. And through the scraper 92 abutting against the outer wall of the drum 91, during the rotation of the drum 91, the scraper 92 can scrape and collect the steel slag adsorbed on the outer wall of the drum 91, so that the steel slag can be screened and separated efficiently by the drum 91. It should be noted that the drum 91 is powered by a motor, that is, a motor is provided at one end of the drum 91, and the shaft of the motor is connected to the shaft of the drum 91, so that the drum 91 is driven to rotate by the motor.

[0054] In this optional embodiment, the open end of the air inlet housing 11 is connected to the air inlet at the upper end of the magnetic separation device housing 1. The connection through an open end ensures that the gas can smoothly enter the air inlet housing 11 from the inside of the device to avoid gas leakage. One side of the pull plate 12 is connected to one end of the magnetic rod 13. The magnetic rod 13 is used to adsorb magnetic impurities in the gas. When the dust-containing gas inside the magnetic separation device housing 1 flows near the magnetic rod 13, the magnetic impurities will be adsorbed by the magnetic rod 13, thereby achieving preliminary purification of the gas. The handle 15 set on the other side of the pull plate 12 facilitates the operator to operate the pull plate 12 and the magnetic rod 13. The magnetic rod through hole opened on the side of the air inlet housing 11 close to the magnetic separation device housing 1 provides an installation channel for the magnetic rod 13, so that the magnetic rod 13 can enter the interior of the air inlet housing 11 through the magnetic rod through hole. The size of the magnetic rod through hole can be set according to the number of magnetic rods 13 set on the pull plate 12. At the position corresponding to the magnetic rod through hole inside the air inlet shell 11, a semi-support ring 14 is provided, that is, a semi-support ring 14 is provided on the inner wall of the side away from the magnetic rod through hole, which is used to support the other end of the magnetic rod 13, ensure the stability of the magnetic rod 13 during operation, and prevent it from being displaced due to air flow impact or equipment vibration. The number of the semi-support rings 14 matches the number of magnetic rods 13. The pull plate 12 fits with the air inlet shell 11, ensuring that the gas can only pass through the space around the magnetic rod 13 when flowing through the area, improving the adsorption efficiency of the magnetic rod 13 on magnetic impurities, and preventing leakage. The air inlet through hole on the side of the air inlet shell 11 away from the magnetic separation equipment shell is connected to the suction pipe 32 of the compressor 3. Under the suction force of the compressor 3, the gas after flowing through the magnetic rod 13 is sucked into the suction pipe 32, thereby maintaining the air flow circulation and pressure balance inside the magnetic separation equipment, and ensuring the stable operation and good working environment of the entire magnetic separation equipment.

The third support leg 73 and the fourth support leg 74 are fixed at one end of the bottom of the magnetic separation device away from the chute 6, and together with the first support leg 71 and the second support leg 72, they constitute the bracket 7 at the bottom of the equipment. The stability and integrity of the bracket 7 are further enhanced by the crossbeam. The two ends of the first crossbeam 75 are respectively connected to the first support leg 71 and the second support leg 72 and are located below the chute 6, which not only strengthens the connection between the two support legs, but also prevents the chute 6 from being excessively deformed due to the weight of the material. The two ends of the second crossbeam 76 are respectively connected to the second supporting foot 72 and the third supporting foot 73, the two ends of the third crossbeam 77 are respectively connected to the third supporting foot 73 and the fourth supporting foot 74, and the two ends of the fourth crossbeam 78 are respectively connected to the fourth supporting foot 74 and the first supporting foot 71. They are intertwined to form a closed frame structure, which tightly connects the four supporting feet together, effectively dispersing the weight of the equipment and the various forces generated during operation, ensuring that the equipment can maintain a stable posture under different working conditions.

[0058] Furthermore, one end of the compressor support plate 79 is connected to the second crossbeam 76, and the other end is connected to the fourth crossbeam 78, providing a special installation platform for the compressor 3. The compressor 3 is set on the compressor support plate 79 so that it is in a relatively stable position to avoid being affected by the vibration or displacement of other parts of the equipment. At the same time, through the connection with the crossbeam of the bracket 7, the compressor support plate 79 can use the overall stability of the bracket 7 to ensure that the compressor 3 will not shake or deviate during operation, thereby ensuring that the compressor 3 can continuously and stably provide the required airflow power for the equipment and maintain the normal operation of the entire magnetic separation equipment.
