Detailed implementation manners

[0028] As Figure 1-8As shown in the figure, a wet permanent magnet drum magnetic separator for mining processing engineering that is easy to move includes a frame 1. On both the left and right sides of the frame 1, a set of first driving devices 2 are installed. In each set of the first driving devices 2, there are two first driving devices 2, and the two first driving devices 2 are arranged side by side front and back. At the top of each set of the first driving devices 2, a support frame 3 is connected. Between the two support frames 3, an installation frame 4 is rotatably installed. On both the left and right sides of the installation frame 4, a rotating shaft is connected, and the rotating shaft is rotatably installed on the support frame 3 through bearings. Inside the installation frame 4, a combined box body 6 is connected. On one of the support frames 3, a second driving device 5 for driving the installation frame 4 to rotate is installed. At the rear of the frame 1, a lifting device 7 is installed. At the front of the lifting device 7, a cylinder body 8 is rotatably installed. At the front of the cylinder body 8, a third driving device 9 for driving the cylinder body 8 to rotate is installed. Inside the cylinder body 8, a permanent magnet magnetic system 12 is installed. Specifically, the first driving device 2 is a hydraulic cylinder, and the second driving device 5 and the third driving device 9 are both motors.

[0029] A moving wheel set 1-1 is installed on the bottom surface of the frame 1, which is convenient for the movement and transfer of the magnetic separator.

[0030] As Figure 4-6 shown in the figure, the combined box body 6 includes a feeding box 6-1. At the lower left of the feeding box 6-1, a bottom flow box 6-2 is connected. Above the bottom flow box 6-2, a screening box 6-3 is connected. The bottom surface of the screening box 6-3 is set as an arc surface, and the arc surface matches the cylinder body 8, and the diameter of the arc surface is larger than the outer diameter of the cylinder body 8. Between the screening box 6-3 and the bottom flow box 6-2, a first temporary storage box 6-4 is connected. At the bottom of the first temporary storage box 6-4, a first discharge pipe 6-5 is connected. The first discharge pipe 6-5 passes through the bottom flow box 6-2 and extends downward. On the left side of the screening box 6-3, a second temporary storage box 6-6 is connected. At the bottom of the second temporary storage box 6-6, a second discharge pipe 6-7 is connected.

[0031] Specifically, a first feeding port 6-1-1 communicating with the bottom flow box 6-2 is opened at the bottom of the feeding box 6-1. A second feeding port 6-3-1 communicating with the bottom flow box 6-2 is opened on the left side of the screening box 6-3. An outlet 6-3-2 communicating with the first temporary storage box 6-4 is opened on the right side of the screening box 6-3. The height of the outlet 6-3-2 is higher than the height of the second feeding port 6-3-1.

[0032] A dispersing water pipe 10 is installed at the bottom of the underflow box 6-2, and a cleaning water pipe 11 is installed at the top of the second temporary storage box 6-6; the dispersing water pipe 10 and the cleaning water pipe 11 are connected to the external water pipe through a quick connector, and can be disconnected from the external water pipe when the combined box body 6 is turned over and cleaned; the water flow sprayed from the dispersing water pipe 10 can impact the slurry and disperse the agglomerated mineral particles. Only fully dispersed mineral particles can better contact with the magnetic field, thereby achieving effective sorting and improving the magnetic separation efficiency. The water flow of the dispersing water pipe 10 can also make the mineral particles more evenly distributed in the trough body, which can avoid excessive local particle concentration and uneven magnetic field action, thereby improving the stability and efficiency of the entire magnetic separation process; in another embodiment, a stirring paddle can be used instead of the dispersing water pipe to stir the slurry.

[0033] like Figure 7-8 As shown, the lifting device 7 includes a vertical rail 7-1, and the vertical rail 7-1 is connected to the rear side of the frame 1. A lead screw 7-2 is arranged in front of the vertical rail 7-1. The bottom end of the lead screw 7-2 is rotatably connected to the frame 1, and the top end of the lead screw 7-2 is rotatably connected to the mounting plate at the top of the vertical rail 7-1. A lifting seat 7-7 is threadedly connected to the lead screw 7-2, and a moving wheel 7-8 that moves along the vertical rail 7-1 is installed on the lifting seat 7-7. Wheel grooves are arranged on the left and right sides of the vertical rail 7-1, and the moving wheel 7-8 moves up and down in the wheel grooves. A U-shaped connecting frame 7-9 is connected in front of the lifting seat 7-7, and the cylinder is rotatably installed on the connecting frame 7-9. The third driving device 9 is installed on the front side of the connecting frame 7-9, and the output shaft of the third driving device 9 is connected to the cylinder 8. The top of the vertical track 7-1 is installed with a driving mechanism for driving the screw 7-2 to rotate; the driving mechanism includes a lifting motor 7-3, and the lifting motor 7-3 is installed on the top of the vertical track 7-1. The lifting motor 7-3 is connected to the screw 7-2 through a transmission assembly, and the transmission assembly includes a driving wheel 7-4 and a driven wheel 7-5. The driving wheel 7-4 is installed on the output shaft of the lifting motor 7-3, and the driven wheel 7-5 is installed on the top of the screw 7-2. The driving wheel 7-4 and the driven wheel 7-5 are connected through a synchronous belt 7-6.

[0034] The working process of the present invention is as follows:

[0035] Magnetic separation process: The mineral slurry enters the feed box 6-1. The mineral slurry enters the underflow box 6-2 through the first feed port 6-1-1. The mineral slurry enters the screening box 6-3 through the second feed port 6-3-1. The third driving device 9 drives the cylinder 8 to rotate. The mineral slurry comes into contact with the magnetic field area. The mineral particles are under the combined action of the magnetic field, gravity, and water flow in the screening box 6-3. Under the action of the magnetic field, the magnetic mineral particles are adsorbed onto the surface of the cylinder 8. The mineral slurry after magnetic separation enters the first temporary storage box 6-4 through the discharge port 6-3-2 and is discharged through the first discharge pipe 6-5 to form tailings. The magnetic mineral particles reach the left position as the cylinder 8 rotates. The cleaning water pipe 11 flushes the surface of the cylinder 8, causing the flushing water and the magnetic mineral particles to enter the second temporary storage box 6-6 and be discharged through the second discharge pipe 6-7 to form concentrate products.

[0036] Cleaning process of the combined box 6: First, the lifting motor 7-3 drives the driving wheel 7-4 to rotate. The rotation of the driving wheel 7-4 drives the driven wheel 7-5 to rotate through the synchronous belt 7-6. The rotation of the driven wheel 7-5 drives the lead screw 7-2 to rotate. The rotation of the lead screw 7-2 drives the lifting seat 7-7 to move upward, thereby driving the cylinder 8 to move upward. Then, the second driving device 5 drives the mounting frame 4 and the combined box 6 to rotate, making the opening of the combined box 6 face downward. Subsequently, the first driving device 2 drives the support frame 3 to rise, thereby driving the combined box 6 to rise, increasing the height of the combined box 6. The staff can use a water pipe to wash the inside of the combined box 6, and all corners inside the combined box 6 can be washed clean.

[0037] To reduce the wear of the cylinder 8, a filter screen can be installed on the feed box 6-1 to filter the mineral slurry, remove larger particulate matter, and reduce wear.

[0038] In another embodiment, a screw conveyor is installed on one side of the feed box 6-1 to convey the mineral slurry using the screw conveyor. A filter screen is installed on the feed hopper of the screw conveyor for filtering.

[0039] The embodiments described above are only descriptions of the preferred modes of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
