The equipment effectively separates magnetic minerals from non-magnetic minerals in the minerals through the action of a strong magnetic field, thereby improving the grade and recovery rate of the minerals.

DETAILED DESCRIPTION
[0016] In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0017] like Figures 1 to 3 As shown, this embodiment provides a feeding device for a wet high-intensity magnetic ore separator, including a bottom plate 9, on which a first fixed frame 6, a second fixed frame 7 and a third fixed frame 8 are sequentially arranged, a fixed assembly 1 is arranged on the top of the first fixed frame 6, a belt conveyor 3 is arranged on the second fixed frame 7, baffle mechanisms 4 are arranged on both sides of the belt conveyor 3, and a feeding assembly 3 is arranged on the third fixed frame 8.
[0018] The fixing assembly 1 includes a slide rail 11 arranged on the top surface of the first fixing frame 6, and a slider 12 is slidably arranged on the slide rail 11. A fixing seat 13 is connected to the slider 12 for placing a feeding pipe. One side of the slider 12 is connected to the piston rod of the first cylinder 14, and the first cylinder 14 drives the slider 12 to reciprocate along the slide rail 11.
[0019] When feeding ore, the feeding pipe is placed on the fixed seat 13, and the first cylinder 14 drives the fixed seat 13 to reciprocate along the slide rail 11, so that the ore is evenly scattered on the belt conveyor 3, ensuring uniform feeding.
[0020] As a preferred implementation of this embodiment, Figure 4 As shown, the fixing seat 13 is U-shaped, and a closure member 15 is hinged above the U-shaped opening end of the fixing seat 13. When the two closure members 15 are closed, they form a feeding pipe placement platform with the fixing seat 13. This can improve the placement stability of the feeding pipe.
[0021] Further, in order to facilitate the opening and closing of the closure, an unlocking mechanism is provided under the left and right closure members 15, and the unlocking mechanism includes a pressing member 21, which is slidably arranged in the fixing seat 13, a first damper 22 is connected between the bottom of the pressing member 21 and the fixing seat 13, a first spring 23 is sleeved on the outer surface of the first damper 22, a fixing clamp 24 is connected to the side of the pressing member 21 close to the outer side of the fixing seat 15, a sliding member 25 is slidably arranged in the fixing clamp 24, and a first spring 23 is connected between the fixing clamp 24 and the sliding member 25. Second damper 26, the second spring 27 is sleeved on the outer surface of the second damper 26, the other end of the sliding member 25 is slidably set in the slot 28, the slot 28 is opened on the outer side wall of the fixed seat 15, and the end of the slot 28 away from the sliding member 25 is also slidably set with an unlocking member 29; the upper part of the pressing member 21 on the same side as the fixed clamping member 24 is also connected to a connecting rod 210, and the other end of the connecting rod 210 is connected to a push rod 211, the push rod 211 is slidably set in the fixed seat 13, and the top of the push rod 211 is just below the closing member 15.
[0022] When it is necessary to open the closing piece 15, the unlocking pieces 29 on both sides of the fixing seat 13 are pressed, and the unlocking pieces 29 slide inward along the slots 28 to press against the sliding piece 25, and the second damper 26 and the second spring 27 are compressed. When the sliding piece 25 is completely free from the restriction of the slots 28, the pressing piece 21 moves upward under the resetting action of the first damper 22 and the first spring 23, and at the same time drives the connecting rod 210 and the push rod 211 connected thereto to move upward, and the push rod 211 will push open the closing piece 15 directly above, and the closing piece 15 opens, making it convenient to place the feeding pipe on the fixing seat 13. As the feeding pipe is put in, the pressing piece 21 is pressed down and moves downward, and the push rod 211 moves downward accordingly to release the pressure on the closing piece 15. The closing piece 15 begins to close under the resetting action of the hinge. When the sliding piece 25 moves downward to the position of the slot 28, under the resetting action of the second damper 26 and the second spring 27, the sliding piece 25 slides into the slot 28 again to engage. At this time, the closing piece 15 is completely closed, and the feeding pipe is firmly fixed between the closing piece 15 and the fixing seat 13.
[0023] The fixing seat 13, the sealing member 15 and the unlocking mechanism can be used to simply and conveniently stabilize the feeding pipeline, thereby improving the stability of the reciprocating motion of the feeding pipeline on the slide rail.
[0024] like Figure 1 Figure 2As shown, the baffle mechanism 4 includes a fixed baffle 41 and a sliding baffle 42. The fixed baffle 41 is arranged on the second fixed frame 7 on both sides of the belt conveyor 3. The sliding baffle 42 is slidably connected to the outside of the fixed baffle 41. The outside of the sliding baffle 42 is connected to a push plate 43. The bottom surface of the push plate 43 is connected to the piston rod of the second cylinder 44. The second cylinder 44 is installed on the side plate of the second fixed frame 7. When the second cylinder 44 is working, the extension of the piston rod drives the sliding baffle 42 to move upward along the fixed baffle 41 to increase the height of the baffle.
[0025] As a preferred implementation of this embodiment, Figure 1 Figure 2 Figure 5 As shown, the top of the sliding baffle 42 is rotatably connected to a rotating baffle 46 via a rotating shaft 45, one end of the rotating shaft 45 is connected to a driven wheel 47, the driven wheel 47 is connected to a driving wheel 49 via a transmission belt 48, one end of the driving wheel 49 is connected to the output end of a motor 410, the motor 410 is arranged on a mounting frame 411, and the mounting frame 411 is connected to the outer side of the sliding baffle 42. The driven wheel 47, the transmission belt 48, the driving wheel 49 and the motor 410 constitute a belt transmission mechanism, when the angle of the rotating baffle 46 is adjusted, the motor 410 is started, and the rotating shaft 45 is driven to rotate through the belt transmission mechanism, thereby driving the rotating baffle 46 to rotate to adjust the angle.
[0026] When the feeding pipeline feeds the belt conveyor, the slurry flow is generally large. If the baffle is too low, the ore is easy to overflow or splash. Therefore, by setting the sliding baffle and the rotating baffle, the height and angle of the baffle can be flexibly adjusted to better block the material and prevent it from overflowing or splashing. like Figure 1 Figure 2 As shown, the feeding assembly 5 includes an inclined transport plate 51, the starting end of the inclined transport plate 51 is closely connected to the belt conveyor 3, both sides of the inclined transport plate 51 are connected to the first baffle 52, a plurality of third dampers 53 are connected between the inclined transport plate 51 and the third fixing frame 8, and the outer surface of the third damper 53 is sleeved with a third spring 54. When the material enters the inclined transport plate 51, the third damper 53 and the third spring 54 cooperate to absorb the vibration generated by the inclined transport plate 51 during transportation, thereby reducing the vibration of the entire feeding device and extending its service life.
[0027] As a preferred implementation of this embodiment, the feeding assembly 5 also includes a rotating transport plate 55 rotatably connected to the inclined transport plate 51, a sliding member 56 is connected to the bottom of the rotating transport plate 55, the sliding member 56 is connected to the piston rod of the hydraulic cylinder 57, the hydraulic cylinder 57 is rotatably connected to the rotating seat 58, and the rotating seat 58 is installed on the third fixed bracket 8; the second baffle 59 is closely arranged on both sides of the rotating transport plate 55, one end of the second baffle 59 is connected to the first baffle 52, and the bottom surface is connected to the third fixed bracket 8. When feeding to the wet high-intensity magnetic separator, the rotating transport plate 55 is driven to rotate by retracting the piston rod of the hydraulic cylinder 57, and adjusted to a suitable feeding angle to achieve the best feeding effect.
