[0027] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figure 1 The present invention provides the following technical solution: a magnetic separation and impurity removal device for ore powder, comprising a tank 1 and a planar moving mechanism 2 disposed above the tank 1;

[0029] The planar moving mechanism 2 includes two sets of vertical linear guides, one set of which has two linear guides, and the other set of linear guides is provided on the two linear sliders. The sliders of the linear guides are provided with mounting seats.

[0030] Rotation mechanism 3, which is disposed on the planar moving mechanism 2, includes a vertically arranged shaft tube 301 and a driving member for driving the shaft tube 301 to rotate;

[0031] The shaft tube 301 passes through the mounting base and is rotatably connected to it. The top of the shaft tube 301 is provided with a rotary joint and can be connected to an air compressor through a pipe. The mounting base is fixedly provided with a driving component.

[0032] The cylindrical body 4 is provided in multiple forms and located at the same height. The cylindrical body 4 is movably connected to the shaft tube 301. The cylindrical body 4 is connected to the shaft tube 301 through a telescopic tube 401. In this embodiment, the tube 401 is a corrugated flexible hose.

[0033] An electromagnetic rod 5 is provided in each of the cylinders 4, and a telescopic component 410 is provided in each of the cylinders 4 along its axial direction. The electromagnetic rod 5 is connected to the telescopic component 410. The telescopic component 410 can drive the electromagnetic rod 5 to extend out of the cylinder 4 or retract into the cylinder 4.

[0034] Synchronous adjustment mechanism 6 is disposed on the shaft tube 301 and is connected in a driving connection to each of the cylinders 4;

[0035] When performing the impurity removal work, the powder is placed in the tank 1. The synchronous adjustment mechanism 6 drives the cylinder 4 to rotate to a downward tilted state. Then, the telescopic component 410 drives the electromagnetic rod 5 to move outward until it is inserted into the powder. Then, the rotating mechanism 3 drives the electromagnetic rod 5 to revolve around the shaft tube 301 to remove impurities from the powder in a certain area of ​​the tank 1. During the revolve of the electromagnetic rod 5, it can attract the magnetic substances in the powder. The planar moving mechanism 2 can also drive the electromagnetic rod 5 to move to different areas of the tank 1 to perform impurity removal work.

[0036] When a large amount of impurities are adsorbed on the electromagnetic rod 5, the cylinder 4 is rotated to a vertical position, then the magnetism of the electromagnetic rod 5 is turned off, and the impurities on the electromagnetic rod 5 are discharged through the tube 401 and the shaft tube 301 by the adsorption action of the air compressor.

[0037] To facilitate control of the synchronization adjustment mechanism 6, in a further embodiment, such as Figure 3As shown, the synchronous adjustment mechanism 6 includes a piston cylinder 601 fixedly sleeved on the shaft tube 301, a movable cylinder 602 movably sleeved on the shaft tube 301 and extending one end into the piston cylinder 601, and a transmission rod 603 rotatably connected to the movable cylinder 602 and the cylinder body 4. The shaft tube 301 is provided with a control valve 302 located below the piston cylinder 601. The interior of the piston cylinder 601 is connected to the interior of the shaft tube 301 through an air supply assembly 610.

[0038] When the control valve 302 is closed and the air supply assembly 610 is turned on, air can be input or discharged through the air compressor, which will drive the movable cylinder 602 to move linearly along the shaft tube 301, and then drive the movable cylinder 602 to rotate through the transmission rod 603, thereby changing the tilt angle of the cylinder 4.

[0039] To facilitate coordination with the tilting state of the cylinder 4, control the movable cylinder 602, and the air extraction and impurity removal operations, in a further embodiment, such as... Figure 3 , Figure 4 As shown, the bottom end of the movable cylinder 602 is connected to a piston block via a guide rod that penetrates into the piston cylinder 601. The gas supply assembly 610 includes a gas supply pipe 611 that penetrates the side wall of the shaft tube 301, communicates with the interior of the piston cylinder 601, and is located near its top. The gas supply pipe 611 is located below the piston block and is positioned between two guide rods. One end of the gas supply pipe 611 near the shaft tube 301 has a gradually narrowing air hole 612. A conical sealing block 613 is provided inside the air hole 612. The end of the sealing block 613 away from the shaft tube 301 is connected to the inner wall of the piston cylinder 601 via a first elastic element 614. A trigger element extending to the outside of the piston cylinder 601 is also connected to the sealing block 613.

[0040] In the initial state, the control valve 302 is closed, the transmission rod 603 is away from the piston cylinder 601, the triggering component is in an inactive state, and there is a gap between the sealing block 613 and the air hole 612. After the control valve 302 is closed, the piston block can be driven to move upward by the air pumping of the air compressor, thereby driving the cylinder 4 to rotate and move closer to the shaft tube 301 through the movable cylinder 602 and the transmission rod 603.

[0041] When the cylinder 4 rotates to the vertical position, the transmission rod 603 presses against the piston cylinder 601 and makes the triggering component in the activated state. The sealing block 613 and the air hole 612 are in a sealed state. When the air compressor is pumping air, the sealing state is stronger under the cooperation of the sealing block 613 and the air hole 612. Therefore, the movable cylinder 602 cannot move. At this time, the control valve 302 is opened, but the impurities in the cylinder 4 can be discharged by pumping air.

[0042] After the impurities are discharged, the control valve 302 is closed. Through the air compressor's air delivery effect, as the air pressure increases, the sealing block 613 drives the trigger to overcome the force of the transmission rod 603 and move. The sealing block 613 separates from the air hole 612, and the movable cylinder 602 can move downward, thereby driving the cylinder 4 to rotate away from the shaft tube 301.

[0043] Specifically, the triggering element includes a push rod 615 that is fixedly connected to the blocking block 613 and passes through the side wall of the piston cylinder 601, and the push rod 615 can abut against the transmission rod 603;

[0044] In order to protect the trigger, in a further embodiment, the piston cylinder 601 is provided with a receiving hole 604 on its side wall, the push rod 615 is located in the receiving hole 604 and is fixedly connected to a push block 616, and the transmission rod 603 is provided with an abutment rod 605 that can enter the receiving hole 604 and push the push block 616.

[0045] In order to facilitate the cooperation between the transmission rod 603 and the trigger, in a further embodiment, a blocking cylinder 608 sleeved outside the receiving hole 604 is connected to the piston cylinder 601 through a second elastic member 620. The blocking cylinder 608 is movably connected to the movable cylinder 602 through multiple sets of movable first connecting rods 606 and second connecting rods 607.

[0046] When the movable cylinder 602 moves to near its highest point, the first connecting rod 606 and the second connecting rod 607 overcome the force of the second elastic element 620 and pull the blocking cylinder 608, so that the receiving hole 604 is exposed. When the movable cylinder 602 continues to move upward, the abutting rod 605 enters the receiving hole 604 and cooperates with the push block 616.

[0047] When the movable cylinder 602 moves downward, the blocking cylinder 608 can be reset in time;

[0048] Specifically, such as Figure 5 As shown, the second elastic member 620 includes a fixed cylinder 621 fixed to the piston cylinder 601 and located above the blocking cylinder 608, the top end of the blocking cylinder 608 extending into the fixed cylinder 621 and connected to it by a spring 622.

[0049] Specifically, such as Figure 2 As shown, the cylinder 4 is provided with a sliding seat 402, the electromagnetic rod 5 is connected to the sliding seat 402, the telescopic component 410 is connected to the sliding seat 402, the tube 401 is provided on the side of the sliding seat 402 near the shaft tube 301, and the sliding seat 402 is provided with a through hole 403.

[0050] In order to facilitate the removal of impurities from the electromagnetic rod 5, in a further embodiment, the sliding seat 402 is provided with a rotary drive 420, which is coaxially connected to the electromagnetic rod 5. Through centrifugal force, impurities on the electromagnetic rod 5 can be removed.

[0051] In order to facilitate the adsorption of more impurities, in a further embodiment, the electromagnetic rod 5 is provided with uniformly distributed adsorption grooves 501 on its side.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
