DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1 , the present invention provides the following technical solutions: a magnetic separation and impurity removal device for ore powder, comprising a tank body 1, a plane moving mechanism 2 arranged above the tank body 1;

[0029] The plane moving mechanism 2 includes two sets of vertical linear guide rails, one set of linear guide rails is provided with two, and another set of linear guide rails is provided on the two linear slide blocks, and a mounting seat is provided on the slide block of the linear guide rail;

[0030] A rotating mechanism 3, wherein the rotating mechanism 3 is arranged on the planar moving mechanism 2, and the rotating mechanism 3 comprises 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 seat and is rotatably connected thereto. A rotary joint is provided on the top of the shaft tube 301 and can be connected to the air compressor through a pipeline. A driving member is fixedly provided on the mounting seat.

[0032] Cylinder 4, wherein the cylinder 4 is provided in plurality and is located at the same height, the cylinder 4 is movably connected to the shaft tube 301, and the cylinder 4 is connected to the shaft tube 301 through a retractable tube 401. In this embodiment, the tube 401 is a corrugated hose;

[0033] The electromagnetic rod 5 is provided with a telescopic assembly 410 arranged along the axial direction of each cylinder 4, and the electromagnetic rod 5 is connected to the telescopic assembly 410; the telescopic assembly 410 can drive the electromagnetic rod 5 to extend out of the cylinder 4, or to be recovered into the cylinder 4;

[0034] A synchronous adjustment mechanism 6, which is arranged on the shaft tube 301 and is drivingly connected to each of the cylinders 4;

[0035] When performing impurity removal work, the powder is placed in the tank body 1, and the cylinder body 4 is driven to rotate to a downward tilted state through the synchronous adjustment mechanism 6, and then the electromagnetic rod 5 is driven to move outward through the telescopic component 410 until it is inserted into the powder, and then the electromagnetic rod 5 is driven by the rotating mechanism 3 to produce an orbital motion with the shaft tube 301 as the center to remove impurities from the powder in a certain area of ​​the tank body 1. During the orbital motion of the electromagnetic rod 5, the magnetic material in the powder can be adsorbed, and the electromagnetic rod 5 can also be driven by the plane moving mechanism 2 to move to different areas of the tank body 1 for impurity removal work;

[0036] When more impurities are adsorbed on the electromagnetic rod 5, the cylinder 4 is rotated to a vertical state, and then the magnetism of the electromagnetic rod 5 is turned off, and then the impurities on the electromagnetic rod 5 are discharged through the tube body 401 and the shaft tube 301 through the adsorption effect of the air compressor;

[0037] In order to facilitate the control of the synchronous adjustment mechanism 6, in a further embodiment, 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 with one end extending 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, and the interior of the piston cylinder 601 is communicated with the interior of the shaft tube 301 through a gas transmission component 610;

[0038] The control valve 302 is closed, and the air delivery assembly 610 is opened. Air can be input or discharged through the air compressor to drive the movable cylinder 602 to move linearly along the axial direction of the shaft tube 301, and then the movable cylinder 602 is driven to rotate through the transmission rod 603, thereby changing the inclination angle of the cylinder body 4;

[0039] In order to facilitate the coordinated tilting state of the cylinder 4, control the movable cylinder 602 and the air extraction and impurity removal work, in a further embodiment, as Figure 3 , Figure 4 As shown, the bottom end of the movable cylinder 602 is connected to a piston block through a guide rod penetrating into the piston cylinder 601, and the gas delivery assembly 610 includes a gas delivery pipe 611 penetrating through the side wall of the shaft tube 301 and communicating with the inside of the piston cylinder 601 and arranged near the top thereof, the gas delivery pipe 611 is located below the piston block, and the gas delivery pipe 611 is arranged between two guide rods, and an air hole 612 with a gradually decreasing opening is provided at one end of the gas delivery pipe 611 close to the shaft tube 301, and a conical blocking block 613 is arranged in the air hole 612, and an end of the blocking block 613 away from the shaft tube 301 is connected to the inner wall of the piston cylinder 601 through a first elastic member 614, and a trigger member extending to the outside of the piston cylinder 601 is also connected to the blocking block 613;

[0040] In the initial state, the control valve 302 is closed, and the transmission rod 603 is away from the piston cylinder 601. At this time, the trigger assembly is in an inactive state, and there is a distance between the blocking block 613 and the air hole 612. After the control valve 302 is closed, the air pump of the air compressor can drive the piston block to move upward, thereby driving the cylinder body 4 to rotate and approach the shaft tube 301 through the movable cylinder 602 and the transmission rod 603;

[0041] When the cylinder 4 rotates to a vertical state, the transmission rod 603 is close to the piston cylinder 601 and the trigger assembly is in an actuated state, and the blocking 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 blocking 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, and the air compressor is used to supply air. As the air pressure increases, the blocking block 613 drives the trigger member to overcome the force of the transmission rod 603 and generate movement, the blocking block 613 is separated from the air hole 612, and the movable cylinder 602 can move downward, thereby driving the cylinder body 4 to rotate in a direction away from the shaft tube 301;

[0043] Specifically, the trigger member includes a push rod 615 fixedly connected to the blocking block 613 and penetrating the side wall of the piston cylinder 601, and the push rod 615 can interfere with the transmission rod 603;

[0044] In order to protect the trigger, in a further embodiment, a receiving hole 604 is provided on the side wall of the piston cylinder 601, the push rod 615 is located in the receiving hole 604 and is fixedly connected with a push block 616, and the transmission rod 603 is provided with a resisting 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 member, in a further embodiment, the piston cylinder 601 is connected to a shielding cylinder 608 sleeved outside the accommodating hole 604 through a second elastic member 620, and the shielding cylinder 608 is movably connected to the movable cylinder 602 through multiple sets of first connecting rods 606 and second connecting rods 607 that are movably connected;

[0046] When the movable cylinder 602 moves to a point close to the highest point, the first connecting rod 606 and the second connecting rod 607 overcome the force of the second elastic member 620 to pull the shielding 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 pushing block 616.

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

[0048] Specifically, Figure 5 As shown, the second elastic member 620 includes a fixed cylinder 621 fixed on the piston cylinder 601 and located above the shielding cylinder 608, and the top end of the shielding cylinder 608 extends into the fixed cylinder 621 and is connected thereto through a spring 622;

[0049] Specifically, Figure 2 As shown, a sliding seat 402 is provided in the cylinder 4, the sliding seat 402 is connected with the electromagnetic rod 5, the telescopic assembly 410 is connected with the sliding seat 402, the tube body 401 is arranged on a side of the sliding seat 402 close to the shaft tube 301, and a through hole 403 is provided on the sliding seat 402;

[0050] In order to facilitate the discharge of impurities on the electromagnetic rod 5, in a further embodiment, a rotating driving member 420 is provided on the sliding seat 402, and the rotating driving member 420 is coaxially connected to the electromagnetic rod 5, and the impurities on the electromagnetic rod 5 can be forced to fall off by the centrifugal force;

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

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
