Specifically, the conveying mechanism 110 is a conveying belt in the prior art, the conveying belt is supported by two belt pulleys distributed along the first direction, and a magnetic material is arranged on the belt pulley near the side where the material falls, so as to adsorb the tiny particle ore raw material which is not adsorbed by the sorting device.
The sorting apparatus includes a conveyor belt 210 rotatably mounted to the frame 100 about a horizontal axis, the conveyor belt 210 being positioned above the conveyor mechanism 110, and one side of the conveyor belt 210 adjacent to the conveyor mechanism 110 being moved in a first direction. And the inner ring of the conveyor belt 210 is provided with a magnetic material (not shown) for adsorbing ore; the magnetic material adsorbs the raw materials such as ore in the material to the conveyor belt 210, and drops after moving along with the conveyor belt 210 to a predetermined distance away from the magnetic material.
At least one of the separating means 300 comprises a separator 310, a discharge plate 320, a screen plate 330 and a refining assembly.

The refining assembly is disposed on a side of the screen plate 330 far from the partition plate 310, and includes a plurality of refining plates 350 distributed along a third direction, where the refining plates 350 can move in a direction far from the conveyor belt 210 along the third direction in sequence from a side far from the conveyor belt 210 to a side near the conveyor belt 210 by a distance, and move reciprocally along the second direction while moving along the third direction; the refining plate 350 is always attached to the sieve plate 330 when moving; the side of the refining plate 350 remote from the conveyor belt 210 is provided with a guiding plate 360 for dispersing the material adsorbed on the screen plate 330 while moving with the refining plate 350.
The third direction is perpendicular to the surface of the conveyor belt 210 and the second direction is horizontal and perpendicular to the sides of the conveyor belt 210.
The frame 100 is provided with a first recovery tank 130, a second recovery tank 140, and a third recovery tank 150 which are sequentially arranged along a first direction and are not communicated with each other, and a fourth recovery tank 160.

Ore agglomeration of different particles is detrimental to screening of ore by the screen deck 330 due to the adsorption of magnetic material. Through the sequential movement of the refining plate 350 in the third direction, the ore gathered on one side of the screen plate 330 is spread, and the refining plate 350 moves in the third direction and moves reciprocally in the second direction, so that the ore is spread in the second direction through the guide plate 360, the ore spreading effect is further improved, and the ore is conveniently screened through the screen plate 330.

The inclined surfaces on both sides of the guide plate 360 guide the ore on the screen plate 330 to be primarily split in the second direction as the guide plate 350 moves in the third direction. As the refining plate 350 reciprocates in the second direction, the guide plate 360 deflects under the pushing of the ore and further distributes the ore superimposed on the screen plate 330 during the movement.

In this embodiment, the frame 100 is provided with a limit bump 120, the transmission rod 372 is provided with a push rod 376 for abutting the limit bump 120, the push rod 376 abuts the limit bump 120 through an inclined plane, and the partition plate 310 is urged to be far away from the screen plate 330 through the transmission rod 372 during abutting; a return spring 311 is provided between the baffle 310 and the screen plate 330, and a damping cylinder (not shown) is provided, the return spring 311 urges the baffle 310 to approach the screen plate 330 when the push rod 376 is disengaged from the limit bump 120, and the damping cylinder slowly urges the baffle 310 to approach the screen plate 330. The spacing lugs 120 are located on the front side of the center of the magnetic material within the conveyor 210 in a first direction such that the screen 310 moves further away from the screen 330 as the mineral on the screen 330 tends to pass through the screen 330.
In this embodiment, one side of the discharging plate 320 in the second direction is hinged to the screen plate 330 and is connected to the screen plate 330 through a torsion spring, and the torsion spring makes the discharging plate 320 keep fit with the end of the screen plate 330, so as to seal the material distributing cavity. The stand 100 is further provided with a wedge block 170, and when the discharging plate 320 moves along with the sieve plate 330 to be abutted against an inclined plane on the wedge block 170, the discharging plate rotates under the pushing of the wedge block 170 to open a material distributing cavity, and ore in the material distributing cavity falls to the fourth recycling groove 160 along the discharging plate 320.
When the electromagnetic continuous concentrating machine is used, materials are conveyed by the conveying mechanism 110 to move along the first direction, the conveying belt 210 drives the separating device 300 to rotate above the conveying mechanism 110, magnetic materials in the conveying belt 210 adsorb ores in the materials to the lower side of the conveying belt 210, the ores are gathered on one side of the sieve plate 330 of the separating device 300 along with the movement of the lower side of the conveying belt 210, the ores are screened by the sieve plate 330, small-particle ores enter the separating cavity, and large-particle ores remain on the surface of the sieve plate 330. Until the ore moves over the third recovery tank 150 with the conveyor belt 210, the attraction of the magnetic material to the ore decays, the large-particle ore falls to the third recovery tank 150, and the small-particle ore falls to the fourth recovery tank 160 when the discharge plate 320 rotates to open the distribution chamber. Part of the material remaining on the conveyor 110 falls to the second recovery tank 140, and part of the remaining ore is adsorbed by the magnetic material on the pulley of the conveyor 110 and falls to the first recovery tank 130 when moving over the first recovery tank 130.
In the initial state, the plurality of dredging rods 341 and the plurality of refining plates 350 are all gathered on the side of the screen plate 330 close to the conveyor belt 210, most of the ores absorbed by the magnetic materials in the conveyor belt 210 are gathered on the arc plates 352 of the plurality of refining plates 350, and when the separator 300 moves along with the conveyor belt 210 to the point that the push rod 376 abuts against the limit bump 120, the push rod 376 cooperates with the limit bump 120 through an inclined plane, so that the partition plate 310 moves away from the screen plate 330 through the transmission rod 372. The separator 310 drives the dredging rod 341 furthest from the conveyor belt 210 to move away from the conveyor belt 210 in the third direction through the transmission rod 372, the transmission wheel 371 and the synchronization rod 374, and drives the refining plate 350 furthest from the conveyor belt 210 to move away from the conveyor belt 210 in the third direction through the transmission rod 372, the transmission wheel 371, the synchronization rod 374, the synchronization wheel 373 and the lifting rod 375. The dredging rods 341 farthest from the conveyor belt 210 and the adjacent dredging rods 341 are pulled away from each other by a preset distance to drive the adjacent dredging rods 341 to synchronously move, and so on until the plurality of dredging rods 341 move and are pulled away from each other by the preset distance, the refining plates 350 farthest from the conveyor belt 210 and the adjacent refining plates 350 are pulled away from each other by the preset distance to drive the adjacent refining plates 350 to synchronously move, and so on until the plurality of refining plates 350 move and are pulled away from each other by the preset distance. When the refining plates 350 are pulled apart along the third direction, the ore on the arc plates 352 moves between two adjacent straight plates 351 along the arc plates 352 under the adsorption of the magnetic material in the conveyor belt 210, and is adsorbed on the sieve plate 330 or enters the distributing cavity through the sieve plate 330. The ejector rods 355 on two sides of the refining plate 350 move along the third direction and reciprocate along the second direction under the pushing of the wave surface of the pushing protrusion 332, so that the guide plate 360 is driven to reciprocate along the second direction, the guide plate 360 reciprocates and twists under the pushing of the ore, the ore gathered on the sieve plate 330 can be allocated, and meanwhile, the ore with the dredging rods 341 ejected out of the sieve holes can be pulled out, so that the sieve plate 330 is blocked again.
Until the separating device 300 reaches the upper part of the third recovery tank 150, the pushing rod 376 is not abutted with the limiting bump 120 any more, the baffle plate 310 approaches to the sieve plate 330 for resetting, the plurality of refining plates 350 and the dredging rods 341 gather towards one side close to the conveyor belt 210 under the action of the lifting rod 375 and the synchronizing rod 374, and the two adjacent refining plates 350 approach to the large-particle ore between pushing and dropping. Preferably, to facilitate ore falling, the sides of the straight plates 351 of the refining plate 350 adjacent the conveyor belt 210 are beveled.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
