[0003] For example, the patent with publication number CN219073227U discloses a high-purity iron powder multi-stage screening magnetic separation device, including a main body and an anti-blocking component, a feed port is fixedly connected to the top of the main body, the anti-blocking component is installed on the right side of the feed port, and the anti-blocking component includes a motor, gear 1, gear 2, gear 3, transmission rod, baffle 1, magnetic separator, fine brush, collection box 1, screen 1 and exhaust fan 1. Compared with the existing common multi-stage screening magnetic separation device, the high-purity iron powder multi-stage screening magnetic separation device is put into the feed port, and the motor of the anti-blocking component is started to drive gear 1 and gear 2 to rotate, and the power is transmitted to gear 3 and the transmission rod, so that the baffle 1 drives the magnetic separator and the fine brush to rotate, and the exhaust fan 1 is started, so that the raw material is filtered through the screen and collected in the collection box 1, and a screen 1 is arranged above the exhaust fan, thereby achieving the effect of preventing large particles of raw materials from blocking the screen and improving the filtration efficiency.

[0004] When the existing high-purity iron powder multi-stage screening magnetic separation device is used, the staff pours the iron powder onto the screen, but the iron powder accumulates on the screen, resulting in uneven iron powder feeding. In view of this, we propose a high-purity iron powder multi-stage screening magnetic separation device. Utility Model Content

The sliding of the sliding block drives the spreading plate on the outer wall of the connecting plate to slide along the top of the screen, flattening the iron powder on the top of the screen to avoid iron powder accumulation and uneven iron powder feeding.

[0009] Preferably, the feeding frame has an inclined shape, and the screen is parallel to the bottom of the feeding frame, so that the iron powder can fall from the feeding port into the magnetic separation frame by its own gravity during operation.

[0028] The magnetic separation component is located inside the magnetic separation frame 1 and is used to perform magnetic separation operations on iron powder.

[0029] Based on the above structure, the sliding of the lifting plate 9 drives the two groups of inclined connecting grooves 11 to slide synchronously, and then the sliding of the connecting groove 11 drives the sliding block 13 at one end of the connecting column 12 to slide along the outer wall of the limiting groove 14 through the inclined surface. The sliding block 13 slides and drives the spreading plate 16 on the outer wall of the connecting plate 15 to slide along the top of the screen 6, so as to flatten the iron powder on the top of the screen 6 to avoid the accumulation of iron powder and cause uneven iron powder feeding.

[0030] In one embodiment, the outer shape of the feeding frame 2 is inclined, and the screen 6 is parallel to the bottom of the feeding frame 2 .

[0031] In this embodiment, the iron powder can fall into the magnetic separation frame 1 from the feeding port 3 by its own gravity.

[0032] In one embodiment, the connecting groove 11 is inclined in shape, and the sliding block 13 forms a sliding structure through the connecting groove 11 and the connecting column 12 and the limiting groove 14 .

[0035] In this embodiment, the sliding block 13 slides to drive the spreading plate 16 on the outer wall of the connecting plate 15 to slide along the top of the screen 6, spreading the iron powder on the top of the screen 6 to avoid accumulation of iron powder and uneven iron powder feeding.

[0036] In one embodiment, the magnetic separation assembly comprises:

[0037] A grading magnetic separation drum 17 is provided on the inner wall of the magnetic separation frame 1 below the loading port 3, one side of the grading magnetic separation drum 17 is located at one end of the magnetic separation frame 1 and is fixedly connected with a discharge chute 18, one side of the discharge chute 18 is located inside the magnetic separation frame 1 and a conveyor belt 19 is provided, and one end of the conveyor belt 19 is provided with a circulating magnetic separation drum 20.

[0038] In this embodiment, the magnetic force of the magnetic poles inside the grading magnetic separation drum 17 drives the iron powder to fit the outer wall of the grading magnetic separation drum 17, and the non-magnetic material falls onto the conveyor belt 19. When the iron powder is away from the magnetic poles, the magnetic force disappears, and the iron powder falls onto the remaining three groups of grading magnetic separation drums 17 in turn until the iron powder is discharged from the discharge chute 18. Then the non-magnetic material on the conveyor belt 19 will be doped with magnetic material, and the magnetic material in the non-magnetic material will be re-fitted with the outer wall of the grading magnetic separation drum 17 through the circulating magnetic separation drum 20, thereby realizing multi-stage screening and magnetic separation operations on the iron powder.

[0039] In one of the embodiments, four groups of grading magnetic separation rollers 17 are provided, and the four groups of grading magnetic separation rollers 17 are equidistantly and obliquely distributed along the inner wall of the magnetic separation frame 1 .

[0040] In this embodiment, four groups of graded magnetic separation drums 17 are provided to achieve multi-grade screening and magnetic separation of iron powder.

[0041] In one embodiment, the cross-section of the magnetic poles inside the circulating magnetic separation drum 20 and the grading magnetic separation drum 17 is fan-shaped.

[0042] In this embodiment, the magnetic force of the magnetic poles inside the grading magnetic separation drum 17 drives the iron powder to fit the outer wall of the grading magnetic separation drum 17, and the non-magnetic material falls onto the conveyor belt 19. When the iron powder is away from the magnetic poles, the magnetic force disappears, and the iron powder falls onto the remaining three groups of grading magnetic separation drums 17 in turn until the iron powder is discharged from the discharge chute 18, thereby realizing multi-stage cyclic magnetic separation operation of the iron powder.

[0043] When the high-purity iron powder multi-stage screening magnetic separation device of this embodiment is in use, first, the staff pours the iron powder onto the screen 6 in the feeding frame 2, and then the staff presses the handle 10, and the movement of the handle 10 drives the lifting plate 9 to overcome the elastic force of the spring 8 and slide vertically, and the sliding of the lifting plate 9 drives the two groups of inclined connecting grooves 11 to slide synchronously, and then the connecting groove 11 slides through the inclined surface to drive the sliding block 13 at one end of the connecting column 12 to slide along the outer wall of the limiting groove 14, and the sliding of the sliding block 13 drives the spreading plate 16 on the outer wall of the connecting plate 15 to slide along the top of the screen 6, so as to flatten the iron powder on the top of the screen 6 to avoid the accumulation of iron powder and cause uneven iron powder feeding.

[0044] Next, the vibrator 5 works to drive the iron powder to pass through the screen 6 and fall into the bottom of the feeding frame 2. Then, the iron powder falls into the grading magnetic separation drum 17 inside the magnetic separation frame 1 from the feeding port 3 due to its own gravity. The magnetic force of the magnetic poles inside the grading magnetic separation drum 17 drives the iron powder to fit the outer wall of the grading magnetic separation drum 17, and the non-magnetic material falls onto the conveyor belt 19. When the iron powder is away from the magnetic poles, the magnetic force disappears, and the iron powder falls into the remaining three groups of grading magnetic separation drums 17 in turn until the iron powder is discharged from the discharge chute 18.
