The magnetic separation mechanism of the magnetic separator is provided with three groups of rotating motors to drive the three groups of single roller mechanisms to rotate respectively, so that in the process of material falling, the magnetic separation effect on the material is achieved through the three groups of rotating permanent magnet rollers.
[0004] When the magnetic separator in the related art is working, the powder is directly poured into the shell, which easily causes the powder to accumulate and fall, resulting in insufficient contact between the powder and the permanent magnetic roller and poor magnetic separation effect. Utility Model Content
[0005] In order to improve the magnetic separation effect, the present application provides a magnetic separator.
[0006] The magnetic separator provided in this application adopts the following technical solution:
[0007] A magnetic separator comprises a box body with an electromagnetic roller installed, the box body is provided with a feed port and a discharge port, the feed port is located above the discharge port, the box body is also provided with a feed discharge mechanism located above the electromagnetic roller, the feed discharge mechanism comprises a feed discharge plate located below the feed port and a vibration component for vibrating the feed discharge plate, a plurality of feed discharge holes are formed on the feed discharge plate, and the feed discharge plate is inclinedly arranged in the box body from a side close to the feed port to a side away from the feed port.
[0008] By adopting the above technical solution, when the powder enters the box from the feed port, the powder first falls onto the discharge plate, and some fine powder passes through the discharge hole and falls vertically directly onto the electromagnetic roller. The vibration component reduces the blockage of the discharge hole, ensuring that the fine iron powder can be effectively adsorbed by the electromagnetic roller. The powder with large particles slides along the inclined surface of the discharge plate to the side away from the feed port, and finally falls on the electromagnetic roller, thereby enhancing the contact effect between the powder and the electromagnetic roller and improving the magnetic separation efficiency.
[0009] Optionally, the blanking plate includes a plurality of screening parts and connecting parts, and the connecting part is vertically fixed between two adjacent screening parts, so that the blanking plate is stepped.
[0010] By adopting the above technical solution, the stepped discharge plate increases the residence time of the powder in the box, so that the powder is evenly dispersed on the electromagnetic roller, reducing the situation where the magnetic separation effect is poor due to the accumulation of powder.
[0011] Optionally, the screening parts all have an inclined surface which gradually slopes downward from a direction close to the feed inlet to a direction away from the feed inlet.
[0012] By adopting the above technical solution, the inclined surface of the screening part helps the powder to flow along the length direction of the discharge plate and finally be adsorbed by the electromagnetic roller, so that materials of different particles can be effectively adsorbed by the electromagnetic roller, thereby improving the magnetic separation effect.
[0013] Optionally, a connecting rod is vertically fixed to the lower side of the connecting portion, and a guide plate is fixed to one end of the connecting rod away from the connecting portion.
[0014] By adopting the above technical solution, the powder falling from the discharge hole can be evenly dispersed under the guidance of the guide plate. When the discharge plate is vibrated, the guide plate vibrates accordingly, which has the effect of dispersing the material and enhancing the magnetic separation effect.
[0015] Optionally, the guide plate has an inclined surface that gradually slopes downward from close to the connecting rod to away from the connecting rod.
[0016] By adopting the above technical solution, the inclined surface of the guide plate helps the dispersed powder to fall quickly.

Fixed plates are fixed on the mounting plates, and the fixed plates extend in the direction away from the blanking plate. Fixed blocks are fixed in the box body, and the fixed blocks are located below the fixed plates, and a spring is fixedly installed between the fixed blocks and the fixed plates.
[0018] By adopting the above technical solution, when powder falls on the lower feeding plate, the lower feeding plate will shake under the action of the spring, thereby promoting the dispersion of the powder.
[0019] Optionally, the vibration assembly includes a vibration motor fixed on the box body, a turntable is fixed to the output end of the vibration motor, a rotating column is fixed to the side of the turntable away from the vibration motor, the rotating column is located on the side close to the edge of the turntable, a rotating rod is rotatably mounted on the rotating column, the rotating axis of the rotating rod is parallel to the axis of the turntable, a knocking rod is rotatably mounted on the end of the rotating rod away from the rotating column, a fixing ring is fixed to the side wall of the box body, the knocking rod vertically extends into the fixing ring, and the knocking rod is slidably connected to the fixing ring, and the end of the knocking rod away from the rotating rod can abut against the fixed plate.
[0020] By adopting the above technical solution, the vibration motor drives the turntable to rotate, so that the knocking rod knocks on the fixed plate, thereby achieving a vibration effect on the discharge plate, reducing the material blocking the discharge hole, and promoting the powder to slide down along the inclined discharge plate, and finally the iron powder is adsorbed by the electromagnetic roller.
[0021] Optionally, the electromagnetic roller is rotatably installed in the box, the length direction of the electromagnetic roller is parallel to the length direction of the blanking plate, a mounting shaft is fixed at the center of the electromagnetic roller, a drive motor is fixed at one end of the mounting shaft away from the electromagnetic roller, and the drive motor is fixed on the side wall of the box.
[0022] By adopting the above technical solution, the driving motor drives the electromagnetic roller to rotate, so that each side of the electromagnetic roller can adsorb the iron powder in the powder, thereby improving the magnetic separation effect.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. When the powder enters the box from the feed inlet, it first falls onto the discharge plate, and some fine powder passes through the discharge hole and falls vertically directly onto the electromagnetic roller. The vibration component reduces the blockage of the discharge hole, ensuring that the fine iron powder can be effectively adsorbed by the electromagnetic roller. The large-particle powder slides along the inclined surface of the discharge plate to the side away from the feed inlet, and finally falls onto the electromagnetic roller, thereby enhancing the contact effect between the powder and the electromagnetic roller and improving the magnetic separation efficiency;
[0025] 2. The stepped discharge plate increases the residence time of the powder in the box, making the powder evenly dispersed on the electromagnetic roller, reducing the situation where the powder accumulation causes poor magnetic separation effect;

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.
[0033] The embodiment of the present application discloses a magnetic separator.
[0034] Reference Figure 1 and Figure 2 The magnetic separator includes a vertically arranged box body 1, a feed port 11 is provided at the upper end of the box body 1, a discharge port 12 is provided on a side wall of the box body 1 near the bottom, and the bottom wall of the box body 1 has an inclined surface which gradually tilts downward from away from the discharge port 12 to close to the discharge port 12, so that the powder after magnetic separation can automatically flow toward the discharge port 12. A feeding mechanism 2 and an electromagnetic roller 3 are also provided in the box body 1. The feeding mechanism 2 is located above the electromagnetic roller 3. The feeding mechanism 2 reduces the accumulation of powder at the feed port 11, so that the powder can be evenly dispersed in the box body 1, and then it is convenient to be adsorbed by the electromagnetic roller 3, thereby improving the magnetic separation effect.
[0035] The electromagnetic roller 3 is arranged horizontally, and the electromagnetic roller 3 is rotatably installed in the box body 1. A mounting shaft 31 is fixed at the axis center of the electromagnetic roller 3, and one end of the mounting shaft 31 passes through the side wall of the box body 1. A driving motor 32 is fixed to the outer wall of the box body 1. The output end of the driving motor 32 is fixedly connected to the mounting shaft 31. The driving motor 32 drives the electromagnetic roller 3 to rotate, further increasing the contact area between the electromagnetic roller 3 and the powder, and improving the magnetic separation effect. When it is necessary to clean the iron powder on the electromagnetic roller 3, the iron powder can be collected by cutting off the power to the electromagnetic roller 3.
[0036] The bottom of the box body 1 has an inclined surface which gradually slopes downward from away from the discharge port 12 to close to the discharge port 12 , so as to promote the powder material falling to the bottom of the box body 1 to automatically flow toward the discharge port 12 .
[0037] Reference Figure 2 and Figure 3 The unloading mechanism 2 includes an unloading plate 21 and a vibration assembly 22. The unloading plate 21 is tilted in the box body 1. The unloading plate 21 is tilted from the side close to the feed port 11 to the side away from the feed port 11. A plurality of unloading holes are opened on the unloading plate 21. Mounting plates 23 are fixed at both sides of the unloading plate 21. The mounting plates 23 are vertically arranged on both sides of the unloading plate 21, and the mounting plates 23 are parallel to the length direction of the unloading plate 21.
[0038] Reference Figure 2 and Figure 4 A fixing plate 24 is fixed to the upper edge of each mounting plate 23, the fixing plate 24 is perpendicular to the mounting plate 23, and the fixing plate 24 extends in a direction away from the blanking plate 21, a fixing block 13 is fixed on the inner side wall of the box body 1, the fixing block 13 is arranged along the length direction of the blanking plate 21, and the fixing block 13 is located below the fixing plate 24, and two springs 25 are fixedly installed between each fixing plate 24 and the fixing block 13, the two springs 25 are distributed at intervals, one end of the spring 25 is fixedly abutted against the fixing plate 24, and the other end is fixedly abutted against the fixing block 13, so that the blanking plate 21 can shake in the box body 1.
[0039] The unloading plate 21 includes a plurality of staggered and fixed screening parts 211 and connecting parts 212. Two adjacent screening parts 211 are fixedly connected by the connecting parts 212. The connecting parts 212 are vertically arranged, so that the unloading plate 21 is stepped and gradually tilted downward in the direction away from the feed port 11. Each screening part 211 has an inclined surface that gradually tilts downward from the direction close to the feed port 11 to the direction away from the feed port 11, thereby promoting the downward flow of powder.
[0040] When the powder is added from the feed port 11, it first falls onto the discharge plate 21, and the fine powder can slide vertically from the discharge hole, so that the fine iron powder is adsorbed by the electromagnetic roller 3, and the powder with larger particles continues to flow on the discharge plate 21, and finally falls to the electromagnetic roller 3. The discharge plate 21 can realize the rapid dispersion of the powder and reduce the situation where the magnetic separation effect is poor due to the accumulation of powder.
[0041] A connecting rod 2121 is vertically fixed to the lower end of each connecting portion 212, and a guide plate 2122 is fixed to the lower end of the connecting rod 2121. The connecting rod 2121 is fixed to the middle section of the guide plate 2122, and the guide plate 2122 is gradually inclined downward from the direction close to the connecting rod 2121 to the direction away from the connecting rod 2121.
[0042] Reference Figure 3The vibration assembly 22 includes a vibration motor 221 fixed to the outer wall of the box body 1, the output end of the vibration motor 221 extends into the box body 1 and a turntable 222 is coaxially fixed to the output end of the vibration motor 221, the turntable 222 is located in the box body 1, a rotating column 223 is vertically fixed to the side of the turntable 222 away from the vibration motor 221, the rotating column 223 is located on the side close to the edge of the turntable 222, a rotating rod 224 is rotatably installed on the rotating column 223, the rotating axis of the rotating rod 224 is parallel to the axis of the turntable 222, and the rotating rod 224 is away from the rotating column 223 A knocking rod 225 is rotatably installed on one end, and a fixing ring 14 is fixed on the side wall of the box body 1 close to the mounting plate 23. The knocking rod 225 vertically extends into the fixing ring 14, so that the knocking rod 225 can slide up and down in the fixing ring 14, and the end of the knocking rod 225 away from the rotating rod 224 can abut against the fixing plate 24. In the process of the vibration motor 221 driving the turntable 222 to rotate, the rotating rod 224 is driven to rotate, thereby realizing the up and down sliding of the knocking rod 225 in the fixing ring 14, realizing the knocking vibration of the fixing plate 24, and then realizing the vibration unloading of the unloading plate 21.
[0043] The implementation principle of a magnetic separator in an embodiment of the present application is as follows: when the powder containing iron powder enters the box body 1 from the feed port 11, some fine powder passes through the discharge plate 21 and falls vertically directly onto the electromagnetic roller 3, and the vibration component 22 vibrates the discharge plate 21 to reduce the blockage of the discharge hole. During the vibration of the discharge plate 21, the accumulated powder disperses in the direction away from the feed port 11 to reduce the accumulation of powder. After the powder slides to the side away from the feed port 11, it finally falls on the electromagnetic roller 3. After the electromagnetic roller 3 is energized, it generates magnetism and rotates under the drive of the drive motor 32, ensuring that the side of the electromagnetic roller 3 can evenly absorb the iron powder, thereby enhancing the contact effect between the powder and the electromagnetic roller 3 and improving the magnetic separation efficiency. When the iron powder on the electromagnetic roller 3 needs to be collected, the iron powder can be collected by turning off the power to the electromagnetic roller 3.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
