Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic separation, and particularly relates to a magnetic separation device for iron concentrate processing. Background Technique

[0002] Magnetic separation belongs to the beneficiation of iron ore. It utilizes the different magnetic permeabilities of various minerals to make them pass through a magnetic field. Due to the different reactions of different minerals to the magnetic field, minerals with high magnetic permeability are sucked up by the magnetic disk and then fall off after demagnetization. They are collected through the aggregate funnel, while minerals with low magnetic permeability are not sucked up and remain in the material or are taken out as tailings along with the rotating belt, thus achieving separation.

[0003] When the existing magnetic separation device for iron concentrate processing is in use, iron concentrate is prone to accumulate on the feeding plate and needs to be manually scraped by workers. In view of this, we propose a magnetic separation device for iron concentrate processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a magnetic separation device for iron concentrate processing to avoid the problem that iron concentrate is prone to accumulate on the feeding plate for the above-mentioned existing technical problems.

[0005] In view of this, the utility model provides a magnetic separation device for iron concentrate processing, including a magnetic separation frame. The outer wall of the magnetic separation frame is fixedly connected with a working motor. The output end of the working motor is fixedly connected with a magnetic separation roller rotatably connected to the top of the magnetic separation frame. One side of the magnetic separation roller is located at the top of the magnetic separation frame and is fixedly connected with a feeding frame. The outer wall of the feeding frame is rotatably connected with a discharging roller belt-connected to one end of the magnetic separation roller. The outer wall of the discharging roller is provided with a guiding groove. A guiding block is slidably connected to the outer wall of the guiding groove. The bottom end of the guiding block is rotatably connected with a connecting block. A limiting rod fixedly connected with the outer wall of the feeding frame penetrates through the inner wall of the connecting block. The bottom end of the connecting block is rotatably connected with a discharging plate. The bottom end of the discharging plate is attached to a feeding plate fixedly connected with the bottom end of the feeding frame. Both ends of the edge of the feeding plate are fixedly connected with switching columns;

[0006] A cleaning component, which is located at the top of the magnetic separation frame and is used to scrape off impurities attached to the outer wall of the magnetic separation roller.

[0007] Based on the above structure, the rotation of the discharging roller drives the rotation of the guiding groove. Furthermore, the rotation of the guiding groove drives the connecting block to slide along the outer wall of the limiting rod through the guiding block. The sliding of the connecting block drives the discharging plate to slide along the top of the feeding plate. When the connecting block slides to one end of the limiting rod, the discharging plate is driven to rotate in the reverse direction through the switching column, and the iron concentrate accumulated on the feeding plate is quickly scraped off.

[0008] Preferably, there are two sets of the guiding grooves, and the two sets of guiding grooves are connected end to end. The outer shape of the guiding groove is spiral. During operation, by arranging two sets of guiding grooves connected end to end, it is convenient to drive the connecting block to slide back and forth through the rotation of the guiding groove.

[0009] Preferably, the connecting block and the limiting rod form a sliding structure through the guiding groove and the guiding block, and the limiting rod is parallel to the magnetic separation frame. During operation, the rotation of the guiding groove drives the connecting block to slide along the outer wall of the limiting rod through the guiding block, and the sliding of the connecting block drives the discharge plate to slide along the top of the blanking plate, so as to quickly scrape the iron concentrate accumulated on the blanking plate.

[0010] Preferably, the blanking plate and the connecting block form a rotating structure through the switching column. During operation, when the connecting block slides to one end of the limiting rod, the discharge plate is driven to rotate in the reverse direction through the switching column.

[0011] Preferably, the cleaning assembly includes:

[0012] A water spraying pipe. A water spraying pipe is fixedly connected to the top of the magnetic separation frame above the blanking frame. Above the water spraying pipe, a cleaning frame is fixedly connected to the top of the fixedly connected magnetic separation frame. An adjusting bolt is arranged on the outer wall of the cleaning frame, a connecting slider is threadedly connected to the outer wall of the adjusting bolt, a fitting plate is fixedly connected to the outer wall of the connecting slider, and a cleaning brush that fits the outer wall of the magnetic separation drum is fixedly connected to the bottom end of the fitting plate. A feeding port connected to the inner wall of the magnetic separation frame is fixedly connected to one end of the magnetic separation frame away from the blanking frame, and a slag discharge port extending to the inner wall of the magnetic separation frame is fixedly connected to the bottom end of the magnetic separation frame. During operation, the staff pours the iron-containing solution into the magnetic separation frame from the feeding port, and the non-magnetic substances in the iron-containing solution are discharged from the slag discharge port. At the same time, the magnetic poles inside the magnetic separation drum drive the magnetic substances in the iron-containing solution to adhere to the magnetic separation drum through their own magnetic force. Then, the working motor drives the magnetic substances on the outer wall of the magnetic separation drum to rotate. When the magnetic substances are far away from the magnetic poles inside the magnetic separation drum, the staff sprays water onto the outer wall of the magnetic separation drum through the water spraying pipe, so that the magnetic substances fall into the blanking plate, realizing the magnetic separation operation of the iron concentrate. When the magnetic separation drum is working, some magnetic substances will adhere to the top of the magnetic separation drum. The staff rotates the adjusting bolt, and the rotation of the adjusting bolt drives the connecting slider to slide along the outer wall of the cleaning frame through the thread, and the sliding of the connecting slider drives the cleaning brush on the outer wall of the fitting plate to fit the outer wall of the magnetic separation drum, and the magnetic substances attached to the top of the magnetic separation drum are scraped off through the relative rotation of the magnetic separation drum and the cleaning brush.

[0013] Preferably, there are two sets of the adjusting bolts, and the fitting plate is parallel to the magnetic separation drum. During operation, the rotation of the adjusting bolt drives the connecting slider to slide along the outer wall of the cleaning frame through the thread, and the sliding of the connecting slider drives the cleaning brush on the outer wall of the fitting plate to fit the outer wall of the magnetic separation drum.

[0014] Preferably, the connection surface between the cleaning brush and the magnetic separation roller is arc-shaped. During operation, it is beneficial for the cleaning brush to closely fit the magnetic separation roller, improving the cleaning efficiency of the magnetic separation roller.

[0029] Based on the above structure, the rotation of the discharging roller 5 drives the rotation of the guiding groove 6. Furthermore, the rotation of the guiding groove 6 drives the connecting block 8 to slide along the outer wall of the limiting rod 9 through the guiding block 7. The sliding of the connecting block 8 drives the discharging plate 10 to slide along the top of the feeding plate 11. When the connecting block 8 slides to one end of the limiting rod 9, the discharging plate 10 is driven to rotate in the reverse direction through the switching column 12, so as to quickly scrape off the iron concentrate accumulated on the feeding plate 11.

[0030] In one embodiment, there are two sets of guiding grooves 6, and the two sets of guiding grooves 6 are connected end to end. The shape of the guiding groove 6 is spiral.

The non-magnetic substances in the iron-containing solution are discharged from the slag discharge port 20. At the same time, the magnetic poles inside the magnetic separation roller 3 drive the magnetic substances in the iron-containing solution to adhere to the magnetic separation roller 3 through their own magnetic force. Then, the working motor 2 works to drive the magnetic substances on the outer wall of the magnetic separation roller 3 to rotate.

When the magnetic separation roller 3 is working, some magnetic substances will adhere to the top end of the magnetic separation roller 3. The staff rotates the adjusting bolt 15. The rotation of the adjusting bolt 15 drives the connecting slider 16 to slide along the outer wall of the cleaning frame 14 through the thread.

Then, the working motor 2 operates to drive the magnetic substances on the outer wall of the magnetic separation drum 3 to rotate. When the magnetic substances are far away from the magnetic poles inside the magnetic separation drum 3, the staff sprays water onto the outer wall of the magnetic separation drum 3 through the water spray pipe 13, facilitating the magnetic substances to fall into the blanking plate 11, realizing the magnetic separation operation of the iron concentrate.

[0044] Meanwhile, the rotation of the magnetic separation drum 3 drives the discharge roller 5 to rotate through the belt. The rotation of the discharge roller 5 drives the guide groove 6 to rotate. Furthermore, the rotation of the guide groove 6 drives the connecting block 8 to slide along the outer wall of the limiting rod 9 through the guide block 7.
