Description

Technical Field

[0001] This invention belongs to the field of magnetic separation technology for minerals, specifically relating to a magnetic separator and magnetic separation method for removing titanium from zirconium ore. Background Technology

[0002] Currently, zircon sand is widely used in many fields. However, the zircon concentrate obtained after gravity separation enrichment of natural coastal sand deposits or continental sand deposits usually contains a large amount of titanium-bearing minerals such as ilmenite and rutile, as well as trace amounts of strongly magnetic iron impurities. Since the presence of titanium impurities will significantly reduce the purity, refractoriness and chemical stability of zircon concentrate, it must be purified before deep processing of zircon concentrate.

[0003] In industry, magnetic separation is the main method used to remove titanium from zirconium ore. However, existing magnetic separators mostly use a single magnetic roller or magnetic drum for single-pass separation. When the material moves at high speed, it will stack and agglomerate, which will cause some weakly magnetic or fine-grained titanium minerals to be wrapped by non-magnetic zirconium ore and unable to be removed. Summary of the Invention

The rotating roller is close to the feed inclined pipe, and the end of the feed inclined pipe away from the feed straight pipe is located above the conveyor belt.

[0009] Preferably, the secondary magnetic separation assembly includes a rotating straight plate and a third drive motor. The rotating straight plate is rotatably connected inside the magnetic separation box, and the third drive motor is installed on the outer periphery of the magnetic separation box.

[0011] Preferably, the receiving device includes a flat plate and an inclined plate.

A vertical plate is installed on the side of the inclined plate near the strong magnetic separator, and the vertical plate cooperates with the strong magnetic separator.

[0012] Preferably, the feeding device includes a second flat plate and a second inclined plate. The second flat plate is installed at the bottom of the magnetic separator, and the second inclined plate is installed on the side of the second flat plate near the second magnetic separator component. The second inclined plate cooperates with the second magnetic separator component.

[0013] Preferably, the magnetic separator is equipped with two linear mechanisms and a magnetic separation plate. Each of the two linear mechanisms includes a guide rail and a servo motor.

[0014] A magnetic separation method for removing titanium from zirconium ore, characterized by magnetic separation using a magnetic separator for removing titanium from zirconium ore, comprising the following steps: Step 1: The crushed zircon middlings ore is fed into the feed inlet above the magnetic separator. The zircon middlings ore enters the feed inclined pipe through the feed straight pipe and is diverted and falls onto the strong magnetic conveying component in the feed channel formed by multiple baffles. The zircon middlings ore flows through the weak magnetic plate, and the weak magnetic plate adsorbs the strong magnetic minerals and iron impurities in the zircon middlings ore, completing the initial magnetic separation. Step 2: After weak magnetic pre-selection, the zircon middlings ore is transferred to the receiving device on the strong magnetic conveying component, where the magnetic titanium minerals are adsorbed and conveyed. Non-magnetic or weakly magnetic materials enter the secondary magnetic separation component. Step 3: Non-magnetic or weakly magnetic materials falling from the strong magnetic conveying component enter the secondary magnetic separation component. The secondary magnetic separation component performs secondary adsorption and separation of titanium minerals entrained in the material. The material after secondary magnetic separation enters the re-magnetic separation component. The re-magnetic separation component performs further adsorption and fine selection of the material, further separating the remaining trace amounts of titanium minerals. Step 4: Discharge the magnetic titanium mineral above the receiving device through the corresponding discharge port of the magnetic separator, and discharge the non-magnetic ore above the feeding device through the corresponding discharge port of the magnetic separator.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Most existing magnetic separators use a single magnetic roller or magnetic drum for single separation, while the present invention has a primary magnetic separation device and a secondary magnetic separation device installed in the magnetic separation box. Through secondary magnetic separation, the zircon middlings ore can be effectively separated layer by layer, which improves the purity and recovery rate of zircon concentrate and effectively avoids the problems of entrainment and missed separation caused by single magnetic separation. (2) The feed channel is provided in the feed inclined tube, which consists of multiple baffles. It slows down and disperses the falling ore, so that the material enters the strong magnetic conveying component in a thin layer to avoid stacking and blockage. Then, combined with the weak magnetic plate above the strong magnetic conveying component, it can adsorb large particles of strong magnetic iron impurities and high magnetic minerals in advance, reducing the load of subsequent magnetic separation. (3) The secondary magnetic separation component adopts magnetic separation inclined plate one, magnetic separation inclined plate two and magnetic separation inclined plate three, and the length of the three increases step by step. The contact area and stroke of the material gradually increase during the falling process, so as to fully capture the fine titanium mineral particles. (4) The tilt angle of the rotating straight plate can be adjusted under the action of the drive motor, which not only makes it easy to adjust the material flow rate and throwing distance according to the flowability of the ore, but also adjusts the gap between the end of the magnetic separation inclined plate and the magnetic separation cylinder, thus enhancing the sorting adaptability. (5) A linear mechanism consisting of a servo motor, a ball screw and a slider is configured above the second plate to drive the magnetic separation plate to perform horizontal reciprocating sweeping along the surface of the second plate. This structure can perform deep secondary purification of zirconium concentrate deposited at the bottom layer, adsorb trace amounts of titanium minerals remaining during gravity sinking, and completely eliminate the sedimentation blind zone.

[0050] A magnetic separation method for removing titanium from zirconium ore includes the following steps: Step 1: The crushed zircon middlings ore is fed into the feed inlet above the magnetic separator 1. The zircon middlings ore enters the feed inclined pipe 7 through the feed straight pipe 6. It is then diverted and falls onto the strong magnetic conveying component in the feed channel formed by multiple baffles 28. The zircon middlings ore flows through the weak magnetic plate 8. The weak magnetic plate 8 adsorbs the strong magnetic minerals and iron impurities in the zircon middlings ore, completing the initial magnetic separation. Step 2: After weak magnetic pre-selection, the zircon middlings ore is transferred to the receiving device on the strong magnetic conveying component, where the magnetic titanium minerals are adsorbed and conveyed. Non-magnetic or weakly magnetic materials enter the secondary magnetic separation component. Step 3: Non-magnetic or weakly magnetic materials falling from the strong magnetic conveying component enter the secondary magnetic separation component. The secondary magnetic separation component performs secondary adsorption and separation of titanium minerals entrained in the material. The material after secondary magnetic separation enters the re-magnetic separation component. The re-magnetic separation component performs further adsorption and fine selection of the material, further separating the remaining trace amounts of titanium minerals. Step 4: Discharge the magnetic titanium mineral above the receiving device through the discharge port corresponding to the magnetic separator 1, and discharge the non-magnetic ore above the feeding device through the discharge port corresponding to the magnetic separator 1.

[0051] In this invention, step one includes: turning on drive motor 29, drive motor 30, drive motor 31 and servo motor 34, and feeding the crushed and qualified zirconium middlings ore into the feed inlet at the top of the magnetic separator 1. The zirconium middlings ore falls into the feed inclined pipe 7 through the feed straight pipe 6. The zirconium middlings ore is blocked, buffered and diverted by the feed channel formed by multiple baffles 28 inside the feed inclined pipe 7, so that the zirconium middlings ore can be dispersed into a material layer on the conveyor belt 11 of the strong magnetic conveying component. The zirconium middlings ore flows through the weak magnetic plate 8 on the conveyor belt 11. The weak magnetic plate 8 adsorbs the strong magnetic iron impurities and high magnetic minerals mixed in the zirconium middlings ore, preventing large particles of strong magnetic material from damaging the subsequent strong magnetic components, thus completing the first weak magnetic impurity removal magnetic separation.

[0052] In this invention, step two includes: when the zirconium middlings ore moves with the conveyor belt 11 to the area of ​​the strong magnetic separator roller 9, the magnetic titanium minerals adhere tightly to the surface of the conveyor belt 11 under the action of strong magnetic adsorption force, and pass around the lower part of the strong magnetic separator roller 9, cross the vertical plate 18 and fall onto the inclined plate 19 of the receiving device, and then slide down and collect on the surface of the flat plate 20. The zirconium middlings non-magnetic material or weakly magnetic material that is almost non-magnetic or has very weak magnetic properties detaches from the conveyor belt 11 at the end of the conveyor belt 11 due to gravity and inertia, falls over the vertical plate 18 and enters the secondary magnetic separation component below for deep separation.

[0053] In this invention, step three includes: the non-magnetic or weakly magnetic material thrown in step two falls into the secondary magnetic separation component, and the non-magnetic or weakly magnetic material flows sequentially through magnetic separation inclined plates 13, 14 and 3 with increasing lengths. The magnetic separation inclined plates 13, 14 and 3 adsorb the fine titanium minerals entrained in the material in a stepwise manner. The adsorbed residual titanium minerals remain on the surface of the inclined plates, and the unadsorbed material flows from the end of the magnetic separation inclined plate 3 to the outer periphery of the magnetic separation cylinder 16. The magnetic separator 16 further refines the material, firmly adsorbing the residual trace amounts of titanium minerals. The non-magnetic refined material, freed from titanium impurities, detaches from the magnetic separator 16 and slides down the inclined plate 22 onto the flat plate 2 at the bottom of the feeding device. At this time, the servo motor 34 drives the ball screw 26 to rotate, causing the slider 25 to reciprocate linearly along the guide rail 24. This causes the magnetic separator 27 above the flat plate 2 to reciprocate horizontally and adsorb the material on the surface of the flat plate 2, completing the final magnetic separation of the bottom layer.

[0054] In this invention, step four includes: opening cylinder two 32 and cylinder one 5, the magnetic titanium minerals collected on the receiving device plate one 20 are driven by multiple cylinder two 32 on the outer support plate 33 of the magnetic separator 1 to push the push plate one 21 horizontally along the surface of the plate one 20, pushing the enriched titanium ore to the corresponding discharge port, and sliding along the discharge ramp one 3 into the discharge box one 4 for centralized storage; the high-purity non-magnetic zirconium concentrate remaining on the feeding device plate two is driven by multiple cylinder one 5 installed on the opposite side to push the push plate two 23 forward, pushing the zirconium concentrate to the discharge port at the bottom, and sliding along the discharge ramp two 35 into the discharge box two 36 on the ground for finished product collection.

[0055] In this invention, after the machine is stopped, the opening and closing doors of the magnetic separator 1 at the corresponding positions of the weak magnetic plate 8, the magnetic separation inclined plate 13, the magnetic separation inclined plate 14, the magnetic separation inclined plate 15 and the collection plate 17 are opened to manually clean and remove the titanium minerals and iron impurities adsorbed and accumulated on the surfaces of the weak magnetic plate 8, the magnetic separation inclined plate 13, the magnetic separation inclined plate 14, the magnetic separation inclined plate 15 and the collection plate 17. The cleaning method adopts the existing magnetic separation cleaning method.

10. A magnetic separation method for removing titanium from zirconium ore, characterized in that, Magnetic separation using the zirconium ore titanium removal magnetic separator as described in claim 3 includes the following steps: Step 1: The crushed zircon middlings ore is fed into the feed inlet above the magnetic separator (1). The zircon middlings ore enters the feed inclined pipe (7) through the feed straight pipe (6). It is diverted and falls onto the strong magnetic conveying component in the feed channel formed by multiple baffles (28). The zircon middlings ore flows through the weak magnetic plate (8). The weak magnetic plate (8) adsorbs the strong magnetic minerals and iron impurities in the zircon middlings ore, thus completing the initial magnetic separation. Step 2: After weak magnetic pre-selection, the zircon middlings ore is transferred to the receiving device on the strong magnetic conveying component, where the magnetic titanium minerals are adsorbed and conveyed. Non-magnetic or weakly magnetic materials enter the secondary magnetic separation component. Step 3: Non-magnetic or weakly magnetic materials falling from the strong magnetic conveying component enter the secondary magnetic separation component. The secondary magnetic separation component performs secondary adsorption and separation of titanium minerals entrained in the material. The material after secondary magnetic separation enters the re-magnetic separation component. The re-magnetic separation component performs further adsorption and fine selection of the material, further separating the remaining trace amounts of titanium minerals. Step 4: Discharge the magnetic titanium mineral above the receiving device through the discharge port corresponding to the magnetic separator (1), and discharge the non-magnetic mineral above the feeding device through the discharge port corresponding to the magnetic separator (1).
